Abstract: This disclosure provides systems, methods, and apparatuses for the identification of a channel state information reference signal (CSI-RS) resource. In some aspects, a network entity transmits configuration information indicating a plurality of CSI-RS resources. The network entity selectively transmits the CSI-RS on a selected CSI-RS resource based on a channel access operation and the configuration information. The network entity then selectively receives a CSI report based on the CSI-RS. Signaling or techniques for when no CSI-RS is detected (such as when the network entity fails a channel access operation for all available CSI-RS resources) are also provided. Additionally, approaches for rate matching shared channels around CSI-RS resources or managing CSI interference (CSI-IM) are disclosed, as well as CSI reporting approaches for scenarios when the user equipment (UE) fails to transmit CSI feedback due to a failed channel access operation, including triggered or re-triggered CSI reports.

Abstract: This disclosure provides systems, methods, and apparatuses for adjusting an encoding timing or a decoding timing in a manner that minimizes disruption of ongoing uplink or downlink traffic. Some aspects more specifically relate to decoupling adjustment of the encoding timing and adjustment the decoding timing to enable independent adjustment of the encoding timing or the decoding timing. In some aspects, a user equipment (UE) may perform adjustment of the encoding timing, relative to an active time indicated by a discontinuous reception (DRX) configuration, at a time at which uplink traffic is absent. Additionally, or alternatively, the UE may perform adjustment of the decoding timing, relative to an active time indicated by a DRX configuration, at a time at which downlink traffic is absent. Accordingly, upon receiving a DRX configuration, the UE may wait until a period in which uplink traffic or downlink traffic is absent to perform a timing adjustment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may set a target delay value for a dejitter buffer of the UE based at least in part on jitter delays of silence descriptor (SID) packets that are received by the UE. The UE may receive, after the SID packets, media packets into the dejitter buffer. The UE may release the media packets from the dejitter buffer based at least in part on the target delay 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 a configuration that indicates a number of bits to be used in an indication of at least one of a listen-before-talk (LBT) category or a channel access priority class to be used for uplink communications. The UE may receive the indication of at least one of the LBT category or the channel access priority class to be used for a transmission starting point associated with one or more uplink communications, wherein the indication includes the number of bits indicated in the configuration. The UE may perform an LBT procedure for an uplink communication, of the one or more uplink communications, transmitted at the transmission starting point, according to the LBT category or the channel access priority class. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a voice call. The UE may receive a configuration for a discontinuous reception (DRX) cycle indicating at least an ON duration and a DRX cycle duration. The UE may receive a configuration for a scheduling request (SR) indicating an SR period duration for transmitting an SR. The UE may detect that the SR period duration is greater than the DRX cycle duration. The UE may generate, based at least in part on the SR period duration being greater than the DRX cycle duration, a voice data packet to be available for transmission within a threshold time of a start of the ON duration. The UE may transmit the voice data packet on a resource identified by a grant received from the network. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and apparatuses for the identification of a channel state information reference signal (CSI-RS) resource. In some aspects, a UE that receives the CSI-RS may determine CSI feedback based at least in part on the CSI-RS after detecting the CSI-RS resource that includes the CSI-RS. Signaling or techniques for when no CSI-RS is detected (such as when the base station fails a channel access operation for all available CSI-RS resources) are also provided. Furthermore, approaches for rate matching for a shared channel around CSI-RS resources or for CSI interference management (CSI-IM) resources are provided, as well as CSI reporting approaches for cases when the UE fails to transmit CSI feedback due to a failed channel access operation, such as a triggered or re-triggered CSI report.

Abstract: This disclosure provides systems, methods and apparatuses for listen-before-talk (LBT) failure-based channel congestion measurement and recovery triggering. In one aspect, a user equipment (UE) may determine an LBT metric based on a result of attempting to perform an uplink transmission in connection with an LBT procedure. For example, the UE may determine an absolute quantity of LBT failures, a ratio of unsuccessful uplink transmissions to total uplink transmission attempts, an absolute quantity of LBT successes, or another type of LBT metric. The UE may trigger a recovery action, such as a radio link failure (RLF) recovery action or a bandwidth part switch, based on determining that the LBT metric satisfies a threshold.

Abstract: Aspects described herein relate to receiving multiple synchronization signal blocks (SSBs) from a target cell over a measurement time window. A repeating beam index for one or more of the multiple SSBs can be identified based at least in part on a determination of a repeat parameter indicating a number of beams in a SSB pattern for the target cell. A beam set of the one or more of the multiple SSBs determined to have the same repeating beam index can be associated. One or more parameters of the one or more of the multiple SSBs of the beam set can be measured and reported.
