Abstract: Wireless communication devices, systems, and methods related to handling wake-up behavior for power saving, including during discontinuous reception (DRX) operation are provided. For example, a method of wireless communication includes transmitting, by a base station (BS) to a user equipment (UE), a default wake-up configuration associated with a discontinuous reception (DRX) operation; determining, by the BS, whether to transmit a wake-up signal (WUS) to the UE during a WUS occasion based on a traffic load; and transmitting, by the BS, a physical downlink control channel (PDCCH) signal during a duration associated with the WUS occasion.

Abstract: A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability performs at least a part of initial access based on an initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE switches, after the initial access, to an active downlink BWP and an active uplink BWP that are dedicated for the UEs having the first capability to perform random access, paging, system acquisition, measurement and data communication procedures.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a coordinate switch indication that indicates that the UE is to calculate a first value of a new ephemeris coordinate of a plurality of coordinates. The UE may calculate the first value of the new ephemeris coordinate based on one or more other ephemeris coordinates of the plurality of ephemeris coordinates and may generate ephemeris information, associated with a non-terrestrial communication device, based on the calculation of the first value of the new ephemeris coordinate. The UE may communicate with the non-terrestrial communication device based on the ephemeris information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE associated with a sidelink connection with the first UE, assistance information indicating at least part of a first discontinuous reception (DRX) configuration for a radio access link between the first UE and a base station. The UE may receive at least part of a sidelink DRX configuration for the sidelink connection, wherein an on duration of the sidelink DRX configuration is not aligned with an on duration of the first DRX configuration. The UE may transmit information indicating at least part of the sidelink DRX configuration. The UE may receive, from the base station, a second DRX configuration for the radio access link. The UE may communicate in accordance with the sidelink DRX configuration or the second DRX configuration. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive first downlink control information (DCI) indicating a first redundancy version (RV) index value associated with a hybrid automatic repeat request (HARD) process. The mobile station may transmit, based at least in part on receiving the DCI indicating the first RV index value, data using a second RV index value, the second RV index value being different from the first RV index value. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, downlink control information (DCI) that includes a request for a dropped hybrid automatic repeat request (HARQ) codebook, wherein the DCI indicates a codebook identifier (ID) associated with the dropped HARQ codebook. The UE may transmit, to the network node, the dropped HARQ codebook based at least in part on the codebook ID associated with the dropped HARQ codebook, as indicated in the DCI. Numerous other aspects are described.
