Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, an indication of a demodulation reference signal bundling configuration to be used by the UE for demodulating a grant. The UE may bundle a plurality of demodulation reference signals received across a plurality of slots according to the demodulation reference signal bundling configuration. The UE may perform channel estimation based at least in part on the bundled demodulation reference signals. The UE may demodulate the grant based at least in part on the channel estimation.

Abstract: A reduced-capability user equipment (UE) uses frequency hopping to improve downlink (DL) coverage. Specifically, the UE may receive a physical downlink shared channel (PDSCH) using frequency hopping among a plurality of narrow hands in a wide bandwidth part. A bandwidth of narrow band is not larger than a maximum wireless communication bandwidth of the UE.

Abstract: Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) aggregation across monitoring occasions. A method that may be performed by a user equipment (UE) includes determining a policy for monitoring one or more physical downlink control channels (PDCCHs), wherein the policy allows for mapping control channel elements (CCEs) of a single PDCCH candidate across multiple PDCCH monitoring occasions; and monitoring for signals from a network entity via the one or more PDCCHs according to the determined policy.

Abstract: Methods, computer programs products, and apparatuses for RS availability indication are provided. An example method at a UE may include receiving, from a base station, a PEI comprising a first availability indication for a first set of RS resources in one or more RS occasions. The example method may further include receiving, from the base station, a paging PDCCH comprising a second availability indication for a second set of RS resources in the one or more RS occasions. The example method may further include receiving, from the base station, at least one of the first set of RS resources or the second set of RS resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a plurality of physical downlink control channel (PDCCH) communications in a same PDCCH monitoring occasion in a first cell, and may transmit a plurality of physical downlink shared channel (PDSCH) communications in at least one of the first cell or a second cell. Each of the PDCCH communications schedules a respective PDSCH communication of the plurality of PDSCH communications. A PDCCH communication, of the plurality of PDCCH communications, includes an indication of a counter downlink assignment index that is based at least in part on a combination of a starting symbol and a cell in which an associated PDSCH communication is to be transmitted, a cell index of the cell in which the associated PDSCH communication is to be transmitted, and the PDCCH monitoring occasion. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to configuring a search space set for the communication of downlink control information (DCI) are provided. A first wireless communication device communicates, with a second wireless communication device, a search space (SS) configuration, wherein the SS configuration includes a first search space for uplink scheduling and a second search space for downlink scheduling, the second search space being different than the first search space. The first wireless communication device communicates, with the second wireless communication device, a scheduling grant in one of the first search space or the second search space based on the SS configuration and further communicates data based on the scheduling grant.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives an uplink (UL) cancellation indication (ULCI) from a network entity cancelling resources assigned to the UE for UL transmission and indicating the UE to measure cross-link interference (CLI) from one or more other UEs within the cancelled resources. The UE measures the CLI from the one or more other UEs based on the ULCI. The UE sends a CLI measurement report based on the measured CLI to the network entity.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, an indication of a plurality of transmission schedules for at least one of a plurality of PUSCHs or a plurality of PDSCHs, the indication including a time gap prior to a transmission of each of the plurality of PUSCHs or each of the plurality of PDSCHs. The apparatus may also receive, from the base station, DCI identifying at least one transmission schedule for at least one PUSCH of the plurality of PUSCHs or at least one PDSCH of the plurality of PDSCHs. Further, the apparatus may transmit, to the base station, the at least one PUSCH or receive, from the base station, the at least one PDSCH based on the at least one transmission schedule in the received DCI.
