Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first downlink control information (DCI) repetition, for scheduling a physical downlink shared channel (PDSCH), wherein the first DCI repetition is associated with a first physical downlink control channel (PDCCH) candidate. The UE may receive a second DCI repetition associated with a second PDCCH candidate that is linked to the first PDCCH candidate for DCI repetition. The UE may transmit a feedback associated with a first symbol of a physical uplink control channel (PUCCH) based at least in part on determining a processing time and an additional processing time, wherein determining the additional processing time comprises determining the additional processing time based at least in part on a parameter associated with at least one of the first PDCCH candidate or the second PDCCH candidate. Numerous other aspects are described.

Abstract: The apparatus is configured to transmit and/or receive GDMRS that may be scrambled based on a same scrambling identifier (ID) and shared for a plurality of UEs or channels. The apparatus, in some configurations, is further configured to multiplex, in time, data for the plurality of UEs or channels into different segments within each symbol in a set of symbols. The apparatus is further configured to transmit and/or receive the multiplexed data for the plurality of UEs or channels. In some configurations, the apparatus is further configured to demodulate the received data based on the GDMRS, and extract at least one segment for a UE or a plurality of channels associated with the apparatus within the demodulated data for subsequent decoding at the apparatus. In some configurations the extraction is based on a SLIV transmitted and/or received by the apparatus.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive group common downlink control information (GC-DCI) including an indication of a periodic communication cancellation resource pattern. The UE may selectively cancel a scheduled periodic communication occasion based at least in part on a determination of whether a resource associated with the scheduled periodic communication occasion overlaps with the periodic communication cancellation resource pattern. Numerous other aspects are described.

Abstract: Aspects of a multi-stage multi-PDSCH grant are provided which allow a UE to obtain data in a downlink data burst with more scheduling flexibility than single-stage multi-PDSCH grants. A base station provides the UE in a downlink control channel a first portion of downlink control information which indicates a plurality of downlink data transmissions. The UE monitors the downlink control channel for the first portion of downlink control information. Afterwards, the base station sends to the UE a second portion of the downlink control information including parameters for one of the downlink data transmissions. The base station may also send the UE a third portion of the downlink control information including additional parameters for the downlink data transmission. After the UE obtains the portions, the UE decodes the one of the downlink data transmissions indicated at least in part by the first and second portion of the downlink control information.

Abstract: A configuration for a single transport block spanning over multiple slots and having a noncontiguous time domain allocation. The apparatus configures DCI that schedules a plurality of PDSCH symbols or a plurality of PUSCH symbols with a single transport block that spans more than one slot and at least one gap between two adjacent PDSCH symbols or PUSCH symbols. Each of the plurality of PDSCH symbols or PUSCH symbols are contiguous and have a respective SLIV. The apparatus transmits the DCI to at least one UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may detect that an antenna of a second wireless communication device is to perform a channel sensing procedure on a channel during a time occasion. The first wireless communication device may transmit, during the time occasion in one or more directions other than a direction of the antenna of the second wireless communication device, a signal that satisfies an energy detection threshold. Numerous other aspects are described.
