Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

User equipment having multiple subscriber identity modules with improved suspend / resume operation

The present application relates to devices and components including apparatus, systems, and methods for concatenating in the packet data convergence protocol sublayer or the service data adaptation sublayer in wireless networks.

Communication devices and methods for concatenating service data units

A user equipment (UE) is configured to enter a radio resource control (RRC) CONNECTED state on a first network using a first subscriber identification module (SIM) and an RRC INACTIVE or RRC IDLE state on a second network using a second SIM, transmit, to the first network, a request for a scheduling gap (SG) configuration, wherein, during a duration of the SG, the first network avoids scheduling resources for the UE, receive, from the first network, an indication of the SG configuration to be used, during the duration of the SG, tune away from the first network to perform operations on the second network and after the duration of the SG, tune back to the first network, wherein the RRC CONNECTED state is maintained on the first network during the duration of the SG.

Multi-SIM scheduling gaps

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

Methods, systems, apparatuses, and computer programs for enhancing UE handover. In one aspect, the method can include obtaining a request for a handover event from a UE, wherein the request includes at least (i) a request for access to a primary cell group and (ii) data indicating capabilities of the UE, determining, based on the UE capabilities, that the UE is capable of maintaining communication with a secondary cell group of a base station during handover of the UE to the primary cell group of the first base station, generating based on the determined UE capability, a handover command that instructs the UE to maintain communication with the secondary cell group of the base station during handover of the UE to the primary cell group, encoding the generated handover command for transmission to the UE, and transmitting the generated handover command to the UE.

Handover without secondary cell group (SCG) change

A method performed by a user equipment (UE) is described. The method includes establishing a connection to a network that includes discontinuous reception (DRX) cycles, each DRX cycle including a scheduled OnDuration and a wake up signal (WUS) opportunity corresponding to each of the scheduled OnDurations, when a WUS is received in the WUS opportunity for one of the scheduled OnDurations, configuring the UE to utilize an active mode of processing during the one of the scheduled OnDurations and when a WUS is not received in the WUS opportunity for one of the scheduled OnDurations, configuring the UE to utilize a sleep mode of inactivity during the one of the scheduled OnDurations.

Wake-up signaling during a discontinuous reception cycle

The present application relates to devices and components including apparatuses, systems, and methods to provide technologies for synchronization signaling during handovers.

Technologies for synchronization signaling during handovers

A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network, generating an identifier corresponding to the first credential, and generates a multi-access edge computing (MEC) authorization parameter. The UE then transmits an application registration request message to a server associated with an edge data network, the application registration request message including an indication of the first credential, the identifier corresponding to the first credential and the first authorization parameter. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

User equipment authentication and authorization procedure for edge data network

Provided is a method for a user equipment (UE). The UE generates a first information for the UE for transmission to a network device. The first information is associated with a small data transmission (SDT) procedure in an inactive state of the UE. The UE obtains a first configuration information from the network device. The first configuration information is determined with reference to the first information. The UE determines whether to perform the SDT procedure in the inactive state according to the first configuration information. The UE, in response to determining to perform the SDT procedure in the inactive state, performs the SDT procedure in the inactive state according to the first configuration information.

Power saving for SDT procedure

A user equipment (UE) is configured to receive physical uplink control channel (PUCCH) configuration information associated with PUCCH resource allocation for negative acknowledgement (NACK)-only based hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback for multicast broadcast service (MBS), receive a signal from a base station and transmit HARQ-ACK feedback to the base station in response to the signal.

Radio (NR) multicast broadcast service (MBS)

A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

Radio link control cumulative mode for new radio

A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

Reporting framework for dynamic UE capabilities

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

Techniques discussed herein can facilitate inactive state transmissions for a Base Station (BS) via a 4-step or 2-step inactive state RACH process. One example aspect is a BS including communication circuitry and one or more processors communicatively coupled to the communication circuitry and configured to cause the BS to transmit a radio link quality threshold and an uplink data size for a Radio Resource Control (RRC) inactive data transmission. Receive a Random Access Channel (RACH) preamble in response to the radio link quality threshold and the uplink data size being satisfied. Receive the RRC inactive data transmission, and transmit a RACH message in response to receiving the RRC inactive data transmission.

Systems and methods for providing random access channel (RACH) signaling to user equipment (UE) during inactive direct transmissions

A user equipment (UE) includes a first subscriber identification module (SIM) and a second SIM. The UE is configured to establish a first cellular network connection based on, at least, the first SIM and a second cellular network connection based on, at least, the second SIM. The UE sends, by the first SIM, a first registration request to the network, wherein the first registration request comprises an identification indicating the multi-SIM device is a type of multi-SIM device, receives, by the first SIM, a first registration accept message indicating the first registration request has been accepted, wherein the first registration accept message comprises a first temporary identification for the first SIM and sends, by the second SIM, an access network message comprising one of the first temporary identification or a further temporary identification based on, at least, the first temporary identification.
