Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus can receive SSB grouping information associated with one or more SSB groups, each of the one or more SSB groups including one or more TRPs. The apparatus can also receive at least one of TCI information or QCL information, each of the TCI information and the QCL information indicating an SSB of the one or more SSB groups that is associated with a downlink Tx beam for downlink data or an uplink Rx beam for uplink data. Additionally, the apparatus can communicate the downlink data from or the uplink data to TRPs in a same SSB group or TRPs in different SSB groups based on at least one of the SSB grouping information, the TCI information, or the QCL information.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example, the BS and UE each determine at least one timing value associated with an effective receive time for the PDCCH based upon a reference symbol of the PDSCH.

Abstract: Certain aspects of the present disclosure provide techniques for communication of downlink control information (DCI) piggybacked on a physical downlink shared channel (PDSCH) configured using semi persistent scheduling (SPS). A method that may be performed by a user equipment (UE) includes receiving a message having a configuration for semi persistent scheduling (SPS) of data channels, receiving an indication associated with at least one first downlink control information (DCI) for transmission in at least one of the data channels, and monitoring for the data channels in accordance with the configuration for SPS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a monitoring window for monitoring a search space set for a physical downlink control channel (PDCCH) wakeup signal (WUS), where the monitoring window is a portion of a configured monitoring window for the search space set. The UE may monitor the WUS search space set within the monitoring window for the PDCCH WUS. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for making multi-transmission configuration indicator (TCI) state data scheduling more reliable. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a first signal indicative of a plurality of demodulation reference signal (DMRS) ports. The method may also include receiving, from the BS, a second signal indicative of a first spatial state of a physical channel and a second spatial state of the physical channel. The method may also include communicating data over the second subset and not the first subset, based on which of the plurality of DMRS ports are part of the first subset and which of the plurality of DMRS ports are part of the second subset.

Abstract: This disclosure provides systems, methods, and apparatuses for a beam-based channel access countdown procedure. In one aspect, a channel sensing beam may be permitted to include one or more transmit beams and, thus, may differ from a transmit beam that is to be used for a transmission. As such, defining a manner in which a channel access countdown procedure is performed is desirable. Some aspects described herein provide techniques and apparatus for a beam-based channel access countdown procedure. In some aspects, the systems, methods, and apparatuses described herein provide a beam-based channel access countdown procedure that allows a single channel sensing beam, including multiple transmit beams, to be utilized in association with determining channel availability for the multiple transmit beams, thereby improving performance of beam-based directional transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP. Numerous other aspects are provided.
