PREFERENCE SIGNALING FOR A MULTI-SUBSCRIPTION WIRELESS DEVICE
20230050907 · 2023-02-16 ·

Methods, systems, and devices for wireless communications are described. A user equipment (UE) associated with a first subscription and a second subscription may establish a connection with a base station, the first subscription in a connected state. The UE may use the first subscription to perform a communication activity with the base station while the first subscription is in the connected state. Upon completion of the communication activity, the UE may transmit UE assistance information (UAI) to the base station indicating a preference of the UE to switch the first subscription to an inactive state in response to a release message from the base station.

Activation/deactivation of direct link in dual/multi-connectivity with UE relays

A configuration utilising L1/L2 signaling to activate or deactivate a direct link in dual or multi-connectivity with relaying devices. The apparatus communicates with a base station using a direct link and using a relay link. The relay link comprises a side link between a first UE and a second UE and a second direct link between the second UE and the base station. The apparatus transmits or receives a request to deactivate the direct link based on a determination by at least one of the base station, the first UE, or the second UE that the direct link between the first UE and the base station is to be deactivated. The request to deactivate the direct link comprises L1 or L2 signaling. The apparatus receives a deactivation command to deactivate the direct link.

User equipment and method for small data transmission

A user equipment (UE) and a method for small data transmission (SDT) are provided. The method includes receiving a Radio Resource Control (RRC) release message from a Base Station (BS), the RRC release message indicating an SDT configuration including a Configured Grant (CG) configuration and a timer; initiating a transmission on an Uplink (UL) resource while the UE is in an RRC_INACTIVE state, the UL resource being either configured by the CG configuration or scheduled by a UL grant from the BS; starting or restarting the timer after initiating the transmission; and monitoring a Physical Downlink Control Channel (PDCCH) addressed to a specific Radio Network Temporary Identifier (RNTI) on a specific search space while the timer is running.

Methods for handling periodic radio access network notification area (RNA) update configuration upon reject

According to an aspect, a user equipment, UE, in a suspended state in a Radio Access Network, RAN, in response to expiration of a first timer, transmits an RRCResumeRequest message. The UE receives a reject message in response to the RRCResumeRequest message. In response to the reject message, the UE starts a second timer and subsequently transmits a further RRCResumeRequest message. The further RRCResumeRequest message is received by the network during a period bounded approximately by the lesser of a duration of the second timer and a period of the periodic UE event and the greater of the duration of the second timer and the period of the periodic UE event.
