Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that that the first UE is scheduled to transmit a control signal and a synchronization signal associated with a synchronization signal block. The first UE may transmit, to a second UE during a first set of symbols within a time period, the control signal associated with a sidelink communication. In some examples, the first UE may transmit, to the second UE during a symbol subsequent to the first set of symbols, the synchronization signal associated with the synchronization signal block, and may communicate with the second UE according to the transmitted control signal and the transmitted synchronization signal.

Abstract: Aspects relate to transmission of physical uplink control channel (PUCCH) information. A user equipment may receive a first physical downlink control channel (PDCCH) candidate carried by a control resource set that also carries a second PDCCH candidate, where these PDCCH candidates are associated with different aggregation levels. The user equipment may identify a PUCCH resource for transmission of information (e.g., an ACK or a NACK) that is associated with a physical downlink shared channel (PDSCH) transmission scheduled by the first PDCCH candidate. For example, the user equipment may identify the PUCCH resource based on a control channel element (CCE) index that corresponds to a starting CCE of the first PDCCH candidate and the second PDCCH candidate.

Abstract: Certain aspects of the present disclosure provide techniques for indicating actual transport block size (TBS) on shaping encoding. For example, in shaping encoding, instead of using a compensated rate code (e.g., by padding or truncating) for a fixed number of output bits that is often different from the TBS scheduled, the present disclosure supports using multiple actual TBS for a given nominal TBS to improve efficiency of the shaping encoder. A transmitter (e.g., a network entity or use equipment (UE)) may encode a payload size of bits with a shaping encoder to obtain a transport block (TB), which has an actual TBS. The actual TBS is selected from a set of TBSs based on a nominal TBS. The transmitter then transmits to a receiver, an indication of the actual TBS. The indication enables the receiver to decode the corresponding encoded bits. The transmitter then transmits the TB to the receiver.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a base station (BS), an indicator indicating a set of start times associated with a transmission opportunity, performing a listen-before-talk (LBT) procedure for the transmission opportunity, and transmitting, to a second UE, a communication starting at a selected start time of the set of start times based on the LBT procedure being successful.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a carrier associated with a primary cell (PCell), the carrier configured with a first control resource set (CORESET) pool index value and a second CORESET pool index value. The UE may receive an indication of a set of candidate beams available for a beam failure recovery (BFR) procedure, the set of candidate beams comprising a first subset of candidate beams associated with the first CORESET pool index value and a second subset of candidate beams associated with the second CORESET pool index value. The UE may detect a beam failure on the carrier on an active beam of the primary cell that is associated with the first CORESET pool index value or the second CORESET pool index value. The UE may select a new candidate beam from the set of candidate beams.
