Abstract: Aspects presented herein may enable a wireless device to use periodic reserved resources to serve aperiodic traffic over sidelink. In one aspect, a wireless device reserves a set of periodic resources for sidelink transmission, where the reserved set of periodic resources include reserved resources for SCI and reserved resources for data. The wireless device transmits SCI without a data transmission in a periodic resource for the period. In another aspect, a first wireless device receives a reservation from a second wireless device for a set of periodic resources for sidelink transmission. The first wireless device receives, from the second wireless device, SCI in a period of the periodic resources, the SCI including an indication that the SCI is not associated with a data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some techniques and apparatuses described herein provide resolution of ambiguity with regard to determination of an open loop power control value (e.g., a P0 value) for a user equipment that is configured with at least two downlink control information formats, of which one is configured with a sounding reference signal resource indicator (SRI) field and another is not configured with an SRI field. Numerous other aspects are provided.

Abstract: A method for wireless communications performed by a user equipment (UE) includes receiving a low priority (LP) grant for scheduling an LP uplink transmission in a slot. The LP uplink transmission may overlap a set of high priority (HP) uplink transmissions in the slot. The method also includes determining an uplink shared channel preparation time as a function of a subcarrier spacing (SCS) configuration and a UE processing time capability based on the LP uplink transmission overlapping the set of HP uplink transmissions. The method further includes determining a time period until an expected transmission time for each respective HP uplink transmission of the set of HP uplink transmissions scheduled based on a corresponding HP grant, the time period being a function of the uplink shared channel preparation time and a time duration corresponding to a reported UE capability. The method also includes canceling the LP uplink transmission before a symbol of the LP uplink transmission overlaps an earliest HP uplink transmission of the set of HP uplink transmissions.

Abstract: Aspects relate to a scheduling entity allocating a group of scheduled entities with resources that define an uplink channel, transmitting an uplink cancellation indication (ULCI) to the group of scheduled entities identifying at least some resource blocks and OFDM symbols in the allocated resources that are canceled for use as the uplink channel, obtaining a processing time of a scheduled entity, where the scheduled entity may use the processing time to process a command from the scheduling entity, the processing time is based on a reference subcarrier spacing (SCS) that may be less than or equal to a downlink SCS of a downlink channel carrying the ULCI, and waiting at least the processing time before utilizing the at least some resource blocks and OFDM symbols for a purpose other than the uplink channel. A scheduled entity receives the ULCI and may process the ULCI after expiry of the processing time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information for a plurality of carriers, wherein a set of first carriers of the plurality of carriers are single transmit receive point (single-TRP) carriers and a set of second carriers of the plurality of carriers are multi-TRP carriers; determine, for the plurality of carriers, a distribution that satisfies a per-span capability of the UE, wherein the distribution is of at least one of a plurality of non-overlapped control channel elements or a plurality of blind decodes, wherein the distribution is based at least in part on which carriers, of the plurality of carriers, are single-TRP carriers or multi-TRP carriers; and receive communications on the plurality of carriers in accordance with the distribution. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may generate a set of orthogonal sequences that the UE may use to convey a payload of a number of bits based on a product of an orthogonal matrix and a cell-specific sequence. The UE or the base station, or both, may select a subset of the set of orthogonal sequences based on the number of bits in the payload, and the UE may construct a codebook including the subset of orthogonal sequences. The UE may select an orthogonal sequence from the constructed codebook based on the bits in the payload. The UE may transmit the payload including the number of bits to the base station using the selected orthogonal sequence.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for scheduling and triggering aperiodic channel state information (A-CSI) reporting on a physical uplink control channel (PUCCH) using a downlink grant. An example method generally includes receiving, from a network entity, a downlink grant including a trigger to transmit an aperiodic channel state information (A-CSI) report on a physical uplink control channel (PUCCH), generating the A-CSI report, and transmitting the A-CSI report on the PUCCH using timing and resources indicated in the downlink grant.
