Aspects of the present disclosure provide mechanisms for fast hyper frame number (HFN) resynchronization of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs). A wireless communication device (e.g., a PDCP entity at a wireless communication device) can calculate a current PDCP count of a current PDCP PDU of a plurality of PDCP PDUs received from a radio link control (RLC) sublayer based on a PDCP sequence number (SN) of the current PDCP PDU and an HFN of a first missing PDCP PDU after a successfully received PDCP PDU. The PDCP count may be calculated using the HFN of the first missing PDCP PDU in response to a gap between the PDCP count of the first missing PDCP PDU and the actual PDCP count of the current PDCP PDU being greater than a PDCP window size.

Hyper frame number (HFN) resynchronization of packet data convergence protocol (PDCP) protocol data units

Aspects presented herein may improve a UE's performance by optimizing the CDRX toggling at the UE. In one aspect, a UE transmits, to a base station, a first UE assistance information request, where the first UE assistance information request include s at least one of an updated CDRX cycle or an updated inactivity timer period, and the updated CDRX cycle is different from an initial CDRX cycle and/or the updated inactivity timer period is different from an initial inactivity timer period. The UE adjusts the initial CDRX cycle to the updated CDRX cycle based on the first UE assistance information request. The UE transmits, to the base station after the initial CDRX cycle is adjusted, a second UE assistance information request, where the second UE assistance information request includes at least one of the initial CDRX cycle or the initial inactivity timer period.

User equipment optimization for connected mode discontinuous reception toggling

A wireless communication device is described. The wireless communication device includes a memory and a processor in electronic communication with the memory. The processor is configured to determine a packet data convergence protocol (PDCP) packet count corresponding to a last radio link control (RLC) packet received in-sequence. The processor is also configured to detect a missing PDCP packet based on a comparison of the PDCP packet count and a sequence number of a last PDCP packet received in-sequence.

Layered missing packet detection

This disclosure provides systems, methods and apparatuses for enabling collision mitigation for a user equipment (UE) operating in a dual active mode. In some aspects, the UE may generate a communication for a first subscription in a first time window associated with a first priority for a time domain division pattern with a second subscription. The UE may transmit, using the first subscription, the communication in a second time window associated with a second priority for the time domain division pattern. For example, the second time window associated with the second priority may be a time window in which traffic for the first subscription is prioritized. In some aspects, the UE may select modified periodic intervals for transmissions of a communication to mitigate collisions associated with the time domain division pattern. For example, a transmission time of the periodic communication may be varied (or randomized) over time.

Collision mitigation for a dual subscriber identity module (SIM) dual active (DSDA) user equipment

A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Active (DSDA) mode or a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); determining a recommendation to change the DDS from the first SIM to a second SIM at a modem; informing a user of the recommendation to change the DDS; changing the DDS in response to, at least in part, the recommendation and an input from the user; updating a first state variable to indicate a state of the DDS; and routing internet data to the second SIM.

Management of default data subscription (DDS) in multi-subscriber identity module devices

This disclosure provides systems, methods and apparatuses for a high priority route selection descriptor (RSD) selection timer. A protocol data unit (PDU) session may be established for an application associated with a user equipment (UE). If the PDU session is associated with a lower RSD priority than the highest RSD priority for the application, the UE may initiate an RSD selection timer. After expiration of the RSD selection timer, the UE may try to establish another PDU session for the application with the highest RSD priority for the application. If another PDU session with the highest RSD priority is accepted, the UE may release the initial PDU session with the lower RSD priority and establish a new PDU session with the highest RSD priority. Such implementations may increase data rates, quality of service, and reliability for the application, decrease latency of the application, or decrease power consumption of the UE.

High priority route selection descriptor (RSD) selection timer

A UE may transmit to a base station, and the base station may receive from the UE, via an RRC message, an IDC interference indication. The IDC interference indication may be associated with at least one victim reception or at least one aggressor transmission. The IDC interference indication may include at least one of a first frequency range associated with the at least one victim reception, information associated with the at least one aggressor transmission, a first requested BWP associated with the at least one victim reception, or a second requested BWP associated with the at least one aggressor transmission. The base station may identify at least one interference mitigation measure based on the IDC interference indication. The UE and the base station may communicate based on the at least one interference mitigation measure.

Next level enhancements for 5G NR to improve UE performance

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first edge application server (EAS) discovery message from an application client that is external to the UE. The UE may transmit a second EAS discovery message to an edge enabler server (EES) based at least in part on the first EAS discovery message. The UE may receive, from the EES, an EAS response message. The EAS response message may indicate a failure of a discovery request associated with the application client or the EAS response message may indicate an EAS associated with the application client. The UE may transmit an indication of the failure of the discovery request or an indication of the EAS to the application client. Numerous other aspects are described.

Application client and edge application server discovery with service authorization and location service

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for identifying edge application servers (EASs) to support one or more services of an application client (AC) running on a user equipment (UE). An AC of a UE may send a request for an edge enabler client (EEC) of the UE to identify one or more EASs for one or more services of the AC. The EEC may receive the request and may perform an EAS discovery procedure to identify the one or more EASs. The EEC may then send a response to the AC including identifiers of the one or more EASs (e.g., if the EAS discovery procedure indicated that these EASs are available). Once the AC receives the response, the AC may connect to each EAS of the EASs indicated by the EEC to support a corresponding service of the AC.

Server availability checking for edge computing services

Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a user equipment (UE) to predict a gain state for an initial acquisition procedure. For example, the UE may use a machine learning (ML) model to predict an initial gain state which is likely to result in a successful initial acquisition procedure (e.g., without adjusting the gain state and reattempting the initial acquisition procedure). The UE may input UE history data or crowdsourced data (e.g., from a local network or a cloud-based server) into the ML model to generate a predicted gain state which may be more likely to result in a successful initial acquisition (e.g., without reattempting the initial acquisition procedure). The UE may use the initial gain state generated by the ML model to attempt an initial acquisition procedure with a network entity.

Efficient initial acquisition with gain state prediction using machine learning

This disclosure provides systems, methods, apparatus, and computer programs encoded on a computer storage media for providing user equipment mobility history information to a remote computing platform. In one aspect, a user equipment may store user equipment mobility history information in memory within the user equipment. The user equipment may determine whether a radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, to an inter-radio access technology cell, or to an out of service. The user equipment may transmit the user equipment mobility history information to the remote computing platform in response to determining that the user equipment radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, an inter-radio access technology cell, or an out of service state.

User equipment (UE) mobility history information management

A method includes monitoring, at an upper layer of the UE, PDU activity for one or more PDU sessions that are associated with one or more DNNs. The method includes determining that each of the one or more PDU sessions has a period of inactivity based on at least one of an expiration of an activity check timer, accumulated inactivity cycles, or a dormancy indication associated with each of the one or more PDU sessions. The method includes indicating, to a lower layer of the UE, to provide UE assistance information to a base station for a RRC connection release between the UE and the base station.

Extending UE fast dormancy at upper layers

This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Modifying transmit powers of uplink signals associated with different radio access technologies (RATs)

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, by a first subscription of the UE, a connection to a first network entity using two transmit (Tx) chains of the UE. The UE may receive, by a second subscription of the UE, a paging message from a second network entity. The UE may receive, by the first subscription from the second subscription, a request for the first subscription to enter a mode that supports one Tx chain. The UE, by the first subscription, may reduce the two Tx chains to the one Tx chain for the first subscription. The UE may perform, by the second subscription to the second network entity, the connection setup based at least in part on the first subscription reducing the two Tx chains to the one Tx chain. Numerous other aspects are described.

Performing a connection setup based at least in part on a paging message

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.
