Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to another UE, a sidelink channel state information reference signal (S-CSI-RS) and an indication associated with triggering a non-codebook based precoded S-CSI-RS. The UE may receive, from the other UE, the non-codebook based precoded S-CSI-RS. The UE may transmit, to the other UE, a non-codebook based channel state information (CSI) report medium access control (MAC) control element (MAC-CE) that includes an indication of one or more selected precoding beams based at least in part on the non-codebook based precoded S-CSI-RS. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide improved techniques for monitoring a downlink control channel. For example, a method includes switching, at a first time period, to monitoring a downlink control channel according to a second group of search space sets in an unlicensed spectrum. The method further includes switching, after the first time period, to monitoring the downlink control channel according to a first group of search space sets in the unlicensed spectrum based on at least one of: i) expiration of a timer started based on the switching to monitoring the downlink control channel according to the second group of search space sets; or (ii) end of a channel occupancy time (COT), of a serving cell, during which the UE monitors the downlink control channel according to the second group of search space sets.

Abstract: Aspects of the disclosure relate to a wireless communication device selecting an uplink (UL) power level for an initial message in a random access procedure. For example, the wireless communication device may receive, via a transceiver, an indication that indicates an UL power level calculation technique to use for a random access procedure. The wireless communication device may further determine an UL power level for an initial message in the random access procedure using the UL power level calculation technique. The wireless communication device may further transmit, via the transceiver, the initial message for the random access procedure using the UL power level. Other aspects, embodiments, and features are also claimed and described.

Abstract: In an aspect, a parent node sends a conditional grant for UL transmission to an IAB MT of IAB node. A triggering event for the conditional grant is based at least in part on a communication status of IAB DU of the IAB node (e.g., whether IAB DU is receiving or transmitting data, depending on IAB node duplex capability). In another aspect, IAB DU of IAB node sends a conditional grant for DL transmission to child node. A triggering event for the conditional grant is based at least in part on a communication status of IAB MT of the IAB node (e.g., whether IAB MT is receiving or transmitting data, depending on IAB node duplex capability).

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive a multi-opportunity grant from a network entity, the multi- opportunity grant indicating multiple listen-before-talk (LBT) opportunities for scheduling a transmission between the first UE and a second UE; perform a LBT procedure for one or more slots of a plurality of slots indicated by the multiple LBT opportunities; select a first slot of the plurality of slots corresponding to an earliest available LBT based on performing the LBT procedure; and communicate a transmission to the second UE during the transmission time interval (TTI) of the first slot.
