Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a secondary cell (SCell) is to be activated for the UE or switched from a dormant state to an active state, where the SCell is in a discontinuous reception (DRX) group. The UE may set a DRX state for the SCell based at least in part on determining a DRX state of other SCells in the DRX group or determining that there are no existing SCells in the DRX group. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated power savings configurations for access link and sidelink(s). A wireless node may receive information from a user equipment (UE) over a sidelink. In some aspects, the wireless node forwards the information to a base station (BS) over an access link and receives, from the BS, a first power savings configuration for the access link and a second power savings configuration for the sidelink. In some aspects, the wireless node receives, from a BS, a first power savings configuration for an access link and determines a second power savings configuration for the sidelink based on the information and the first power savings configuration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly to techniques for enhancing packet data convergence protocol (PDCP) duplication, for example, by allowing a user equipment (UE) to autonomously activate/deactivate (uplink (UL)) PDCP duplication. A method that may be performed by a UE includes detecting one or more events related to channel conditions and activating PDCP duplication at the UE in response to the detection. In some cases, the UE may provide a network entity an indication of the PDCP duplication activation/deactivation. In response to the indication, the network entity may, for example, activate/deactivate downlink (DL) PDCP duplication.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for configuring DRX parameters for groups of serving cells operating in different frequency bands. An example method generally includes receiving first discontinuous reception (DRX) configuration parameters for communications with a first group of cells and second DRX configuration parameters for communications with a second group of cells, wherein the first DRX configuration parameters and the second DRX configuration parameters share common starting time parameters; monitoring for communications by cells operating in first frequency resources based on the first DRX configuration parameters; and monitoring for communications by cells operating in second frequency resources based on the second DRX configuration parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may group and selectively multiplex a plurality of random access channel responses (RARs) and radio resource control (RRC) messages in a message B (msgB) communication, together with supplementary scheduling information for other RARs to be mapped to a different msgB communication. The BS may transmit the msgB communication to one or more user equipments. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.

Abstract: Various techniques are proposed to enhance or expand the capabilities or usage of buffer status request (BSR) and scheduling request (SR) in new radio (NR) applications. In an implementation, techniques are proposed to extend the SR in long term evolution (LTE) baseline with additional information to help a base station (e.g., gNB) schedule faster and more efficiently. Moreover, a new BSR triggering condition is proposed to report new data based on particular events instead of being time-based. Modifications being proposed to both BSR and SR can be customized for different numerologies/transmission time intervals (TTIs). Modifications being proposed to SR can also be used to indicate a user equipment (UE) new beam selection after recovering from a beam failure.

Abstract: In an access network, a base station may aggregate data packets for a user equipment (UE) into transport blocks and configure a control channel to allow the UE to sleep between control channel monitoring occasions to save power. Such data aggregation, however, may be subject to changes in traffic load and/or link quality that may result in a too low data rate or too frequent monitoring. A base station that receives data to transmit to the UE and aggregates the data according to configured control configuration parameters of the UE may determine that a link quality or a traffic load for the UE has changed. The base station may reconfigure the control channel configuration parameters of the UE based on at least one of the link quality or the traffic load in order to obtain a data rate that satisfy the traffic load for the UE.

Abstract: Certain aspects of the present disclosure provide techniques for a random backoff procedure in a wireless communication network such as a new radio (NR) network. A method for wireless communications that can be performed by a user equipment (UE) is provided. The method includes sending a random access preamble to a base station (BS) during a random access procedure. The method includes receiving a random access response from the BS including a backoff indicator. The method includes determining whether to send a contention-free random access (CFRA) preamble to the BS during the backoff period based, at least in part, on a type of the random access procedure.
