Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information indicating a capability of the UE to support a rate splitting multiple input multiple output (MIMO) communication. The UE may receive, based at least in part on the capability information, configuration information associated with the rate splitting MIMO communication. The UE may identify, based at least in part on the configuration information, at least one of a downlink control information (DCI) format, a DCI size, one or more DCI fields, or one or more DCI field sizes associated with a DCI communication associated with the rate splitting MIMO communication. The UE may monitor the DCI communication and decoding the rate splitting MIMO communication based at least in part on the configuration information and the DCI communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a secondary user equipment (UE), a first grant to conditionally transmit one or more data messages over a first set of resources upon completion of a detection procedure. The detection procedure may include monitoring a second set of resources for over-the-air (OTA) signals transmitted by a primary UE pursuant to a second grant, where the first set of resources at least partially overlaps the second set of resources. The UE may monitor for the OTA signals from the primary UE, determine that one or more conditions for transmission of the one or more data messages have been satisfied, and transmit the one or more data messages over the first set of resources.

Abstract: Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is to monitor physical downlink control channel (PDCCH) candidates in overlapping PDCCH monitoring occasions in multiple control resource sets (CORESETs) having different quasi co-location type properties on active downlink bandwidth parts of one or more cells, where the UE is configured with multiple downlink control information based multiple transmission/reception point operation. The UE may determine a set of prioritized CORESETs, each of the set of prioritized CORESETs being included in a respective CORESET group of a set of CORESET groups, and monitor one or more PDCCH candidates in the determined set of prioritized CORESETs. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first user equipment (UE) may include monitoring, during an offset before a discontinuous reception on (DRX ON) period, for a sequence in resource elements transmitted by a second UE, receiving, based on the monitoring for the sequence in resource elements, a wake-up signal (WUS) from the second UE, entering a DRX ON mode in response to receiving the wake-up signal, and receiving, from the second UE, a transport block via a physical sidelink shared channel (PSSCH).

Abstract: A method of wireless communication by a sidelink user equipment (UE) includes selecting a sidelink wakeup signal (WUS) resource from a dedicated sidelink WUS resource pool. The sidelink WUS resource pool differs from a sidelink data transmission resource pool. The method also includes transmitting, to a receiver, a WUS on the selected sidelink WUS resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a threshold quantity of downlink control information (DCI) messages the UE is capable of processing in a time duration for each component carrier (CC) that is associated with multiple control resource set (CORSET) pool index (e.g., CORESETPoolIndex) values. The UE may receive a first control message (e.g., a radio resource control (RRC) configuration message) indicating a configuration that enables the UE to process the threshold quantity of DCI messages. The UE may receive a second control message indicating that a CC is configured with the multiple of CORESETPoolIndex values. The UE may receive one or more DCI messages associated with the CC based on the threshold quantity of DCI messages and the CC being configured with the multiple CORESETPoolIndex values.

Abstract: Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.

Abstract: Certain aspects of the present disclosure provide techniques for detecting a potential collision between a scheduled uplink transmission and a synchronization signal block (SSB) and transmitting the scheduled uplink transmission. For example, in cases of inter-cell multi-transmission and reception points (multi-TRP), a user equipment (UE) may not be capable of simultaneously transmitting and receiving on the multiple serving cells. A first serving cell may indicate to the UE of SSB indices that are actually transmitted for a second serving cell. If there is a slot collision between one of the SSB to be transmitted and a scheduled uplink transmission, the UE may not be able to handle such collision. The present disclosure provides techniques for detecting a potential collision between a scheduled uplink transmission and one of the SSBs and transmitting the scheduled uplink transmission when one or more conditions are met.
