This disclosure relates to techniques for performing wireless communications including authentication between user equipment and edge computing servers. One or more edge enabler client(s) operating at a user equipment may authenticate with one or more edge computing server(s). The authentication may use generic bootstrapping architecture, among various possibilities.

Authentication between wireless devices and edge servers

To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Handling high data rates in protocol stack when using high frequency spectrum

Aspects are presented herein of apparatuses, systems, and methods for secondary cell group (SCG) addition. A wireless device may establish communication with a first base station that is comprised in a master cell group (MCG) and a second base station that is comprised in the SCG. The wireless device may maintain timing advance (TA) parameters for performing uplink communication with the second base station. The wireless device may perform a plurality of signal quality measurements after receiving an indication to deactivate the SCG. The wireless device may determine whether to reuse the TA parameters for communicating with the second base station after receiving an indication. The determination may be based on comparing one or more signal quality measurements of the second base station to one or more signal quality thresholds.

Uplink timing synchronization maintenance in secondary cell group

A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises one or more processors configured to process a service configuration signal received from a base station associated therewith. In some aspects, the service configuration signal comprises an indication of one or more service configurations associated with a data transmission that are allowed to be transmitted by the UE during an INACTIVE state of the UE. The one or more processors is further configured to determine the one or more service configurations associated with the data transmission that are allowed to be transmitted by the UE during the INACTIVE state of the UE, based on processing the service configuration signal.

Access control of user equipments for inactive direct transmissions

This disclosure relates to techniques for supporting multiple Quality of Service flows for a service data flow in a wireless communication system. The service data flow may include multiple categories of data with different Quality of Service parameters. Separate Quality of Service flows may be established for each of the categories of data with different Quality of Service parameters. A cellular network and a wireless device communicating data for the service data flow may apply packet detection rules or packet filters to determine on which Quality of Service Flow to communicate data packets of the service data flow, and may communicate the data packets accordingly.

Quality of service framework enhancements for 5G service

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform closed-loop transmission power control in a multi-base station environment with out-of-order scheduling. The network may configure a series of transmission power control commands to indicate to the UE transmission power for one or more transmissions to different base stations. The UE may receive the transmission power control commands, consider information including timing and/or resources associated with the transmission power control commands, and determine transmission power for the transmissions.

System and method for closed-loop uplink power control

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform URLLC scheme selection. The UE may connect to at least one base station. The UE may determine scheduling of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) are within a threshold duration. Based on the PDCCH and the PDSCH being scheduled within the threshold duration, select one or more transmission control indicator (TCI) states for receiving the PDSCH irrespective of TCI state(s) indicated in the PDCCH. The UE may receive the PDSCH using the selected one or more TCI states.

Ultra-reliable low latency communication (URLLC) scheme selection

A device may wirelessly transmit a physical RACH, and a first message on a physical uplink shared channel (PUSCH), in a first step of a 2-step random access channel (RACH) procedure. The device may receive a second message on a physical downlink shared channel in response to successful detection of the first message, in a second step of the 2-step RACH procedure. When detection of the first message is unsuccessful, the device may be instructed to fall back to a 4-step RACH procedure. The device may be configured with one or more first message transmit opportunities (PO), one of which may include one or more PUSCH resource units (PRUs). Some of the communication parameters of the device may be configured to be common for each PO, while other communication parameters may be configured per PRU. Respective new Radio Network Temporary ID values may be defined for the first message and second message.

Framework for two-step random access channel procedure in wireless communications

This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.

Radio resource control connection procedures for remote wireless devices

When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Mechanisms for radio link failure (RLF) reporting to network

A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index, of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

Resolution of mismatch in calculation of random access radio network temporary identifier

Apparatuses, systems, and methods for a wireless device to perform 2-step random access procedures. The disclosure identifies techniques for transmitting and receiving downlink connection configuration information, such as a radio resource control message, in a 2-step random access procedure.
