Abstract: A UE may identify, during a first DRX ON period immediately preceding an existing DRX OFF period, that a first condition is met. The UE may transmit, to a network node, and the network node may receive, from the UE, a request to extend the first DRX ON period based on the first condition being met. The network node may transmit, to the UE, and the UE may receive, from the network node, an indication of approval of the request to extend the first DRX ON period. The UE and the network node may delay a beginning of the existing DRX OFF period by a first time period based on the approval of the request to extend the first DRX ON period.

Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may transmit a sidelink request to reserve a subset of data resources to a second UE, and may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The second UE may transmit a positive sidelink response if it is available for a data transmission. A third UE may transmit a negative sidelink response if it objects to the data transmission. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the subset of the data resources to the second UE.

Abstract: Aspects relate to configuration of a Layer 1 (L1) measurement report. A radio access network (RAN) node (e.g., a base station) can transmit at least one report setting, each associated with a selected information type, to a wireless communication device (e.g., a UE). The selected information type may be selected from a first information type and a second information type. When a report setting is associated with the first information type, the wireless communication device can transmit the L1 measurement report including both beam measurements and beam identifiers corresponding to the beam measurements for the report setting. When the report setting is associated with the second information type, the wireless communication device can exclude the beam identifiers from the L1 measurement report including the beam measurements for the report setting. Other aspects, features, and examples are also claimed and described.

Abstract: A UE receives control signaling that indicates that the UE is scheduled to transmit one or more uplink control channel messages on a first component carrier that overlap in a time domain with one or more uplink shared channel messages scheduled for transmission on a second component carrier. The UE resolves a first overlap of uplink control channels having a same priority level, if present, and resolves, after resolving the first overlap, a second overlap of an uplink control channel and at least one uplink shared channel having the same priority level, if present. The UE resolves two or more channels having a different priority level after resolving the first overlap and the second overlap. The UE transmits one or more uplink transmissions including at least one of the one or more uplink control channel messages and the one or more uplink shared channel messages.
