Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an association between first-stage downlink control information (DCI) and second-stage DCI. The UE may recover the second-stage DCI based at least in part on the indication of the association. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (e.g., a sidelink user equipment (UE), such as a first UE) may receive sidelink communications from a second UE via a sidelink channel. The receiving device may transmit a feedback message to the second UE via a sidelink feedback channel using a first resource configuration, the feedback message based at least in part on the sidelink communications. The receiving device may identify a second resource configuration of the sidelink feedback channel associated with sidelink communications via the sidelink feedback channel. The receiving device may perform the sidelink communications with the second UE via the sidelink feedback channel using the second resource configuration of the sidelink feedback channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a collision between one or more of a first-stage downlink control information (DCI) or a second-stage DCI, of a two-stage DCI, and a symbol in which a physical downlink control channel (PDCCH) is not monitored by the UE. The UE may perform a collision handling for the two-stage DCI based at least in part on the collision, wherein the collision handling is based at least in part on one of: a prioritization of the two-stage DCI, a fallback to a single-stage DCI, or a shift of the first-stage DCI. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for independent scheduling by a first transmission and reception point (TRP) and a second TRP for a user equipment (UE) operable in a multiple TRP (mTRP) mode. A semi-static time division duplexing (TDD) pattern may indicate a set of downlink symbols, a set of uplink symbols and a set of flexible symbols. A portion of the flexible symbols may be dedicated for communications with the first TRP, and the second TRP may not use the portion of the flexible symbols dedicated for communications with the first TRP. The first UE may operate in the mTRP mode in the semi-static downlink symbols or uplink symbols and operate in a single TRP mode in the portion of the flexible symbols dedicated for communications with the first TRP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sidelink synchronization signal block (S-SSB) with a high priority listen-before-talk (LBT) parameter. The UE may communicate with an other UE based at least in part on the S-SSB with the high priority LBT parameter. 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 first downlink control information (DCI) having a first transmission configuration indicator (TCI) field that indicates a pair of TCI states to be used after a first time. The UE may receive second DCI having a second TCI field that indicates a selected one or more TCI states, of the pair of TCI states, to be used for a physical downlink shared channel (PDSCH). Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described in which one or more UEs may communicate with one or more base stations or transmission reception points (TRPs) based on scheduling information provided to the one or more UEs that schedule multiple transport blocks (TBs) for transmission. The multiple TBs may be divided into separate TB groups and different open loop power control parameters may be applied to the separate TB groups. Different open loop power control parameters may be identified based on a parameter set indication field that is included in scheduling information that schedules the multiple TBs. The parameter set indication field may indicate different open loop power control parameter sets with normal or power boosted parameters for different groups of TBs. In cases where multiple TRPs are used for communications, transmissions to different TRPs may have different power parameters based on the TB group and TRP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, first reservation information that indicates a transmit beam that is reserved for communications from the second UE. The first UE may select a receive beam that is paired with the transmit beam. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reader device may transmit a delta message that indicates a frequency difference between a data tone frequency for the reader device and a helper tone frequency. The reader device may transmit a data tone signal at the data tone frequency and a helper tone signal at the helper tone frequency. The helper tone signal may be a waveform that is shared among multiple reader devices. Numerous other aspects are described.
