Abstract: Certain aspects of the present disclosure provide techniques for ultra-reliable low latency communications (URLLC) indications with multi-physical downlink shared channel (PDSCH) and/or multi-physical uplink shared channel (PUSCH) grants. A method that may be performed by a user equipment (UE) includes receiving, from a network entity, downlink control information (DCI) scheduling a plurality of transmissions of a first priority, wherein the DCI comprises at least one field indicating one or more parameters to apply when at least one previously scheduled transmission of a second priority collides with: one or more of the plurality of transmissions of the first priority, or one or more transmissions acknowledging the one or more of the plurality of transmissions of the first priority; and applying the one or more parameters to process the plurality of the transmissions of the first priority.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify, for an initial slot of a periodic interval, a number of symbols included in the initial slot and a length of cyclic prefixes used for the symbols included in the initial slot based on a subcarrier spacing that is configured for wireless communication. The length of a first set of cyclic prefixes may be based on a length of a cyclic prefix calculated for an initial symbol of the initial slot at the configured subcarrier spacing. The wireless device may perform communications based on the determined number of symbols and length of cyclic prefixes included in the initial slot. Performing communications may include allocating resources based on a length of the cyclic prefixes used for the symbols included in the initial slot.

Abstract: Methods, systems, and devices for wireless communications are described. An energy harvesting device, such as a user equipment (UE) or a radio frequency identification (RFID) tag, may receive, from an energy transfer device such as a network node, an energy harvesting signal providing power for the energy harvesting device. The energy harvesting device may transmit, based on the energy harvesting signal, a control message indicating one or more parameters for a square waveform for energy harvesting, a requested duty cycle for the square waveform, or both. The energy harvesting device may receive the square waveform in response to the control message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support physical sidelink shared channel (PSSCH) resource allocation operations. A transmit (TX) user equipment (UE) transmit a physical sidelink control channel (PSCCH) that indicates an allocated PSSCH resource portion. In a first aspect, the portion includes two non-contiguous subchannels. In a second aspect, the PSCCH indicates a layer or a node of a layer of a resource allocation layer structure. In a third aspect, the PSCCH indicates a subchannel group size for an allocated resource, using a bitmask or a value that corresponds to a subchannel and a group size combination. In a fourth aspect, the TX UE determines the portion based multiple values of subchannel and length combinations, the multiple values determined by disabling one or more combinations of a total number of subchannel and length combination for contiguous allocation, or for contiguous and non-contiguous allocation.
