Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may map a code block to resources, of a physical shared channel, that are allocated for data-modulated demodulation reference signals (DMRSs) in which each of the resources carries both at least a portion of a DMRS sequence and data. The wireless communication device may transmit a communication, via the physical shared channel, that includes the code block that is mapped to the resources that are allocated for the data-modulated DMRSs. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to configuring the structures of synchronization signal blocks (SSBs) and SSB burst sets in scenarios where two or more different types of SSB burst sets may be utilized in a wireless communication system (e.g., SSB burst sets including SSBs having different subcarrier spacing (SCS)). The SSB burst sets may be configured to include different components in an SSB (e.g., one or more of primary and second synchronization signals and a physical broadcast channel), include resource allocation information, include a physical-layer cell identity (PCID) configuration for a first SSB burst set that may be used to determine a PCID for a second SSB burst set, and enable quasi co-locating SSBs in a first SSB burst set with a second SSB burst set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive scheduling information that schedules a shared channel that is associated with a first beamforming configuration; determine that a gap between the shared channel and a resource associated with a second beamforming configuration fails to satisfy a threshold, wherein the UE is configured to monitor the resource associated with the second beamforming configuration; and modify at least one of the gap to satisfy the threshold or the second beamforming configuration to match the first beamforming configuration based at least in part on determining that the gap fails to satisfy the threshold. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive synchronization signal block (SSB) information that indicates, for each respective SSB of one or more SSBs, a quantity of how many beams are associated with the respective SSB. The UE may monitor SSBs, determine one or more beams that provide an SSB based at least in part on the SSB information, and direct one or more reception beams toward the one or more beams. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information reference signal (CSI-RS) for multiple beam transmissions. In an example, a first CSI-RS triggering state of one or more CSI-RS triggering states indicates a CSI-RS resource set and associated transmission configuration indication (TCI) states. The CSI-RS resource set includes a plurality of CSI-RS resources. Each CSI-RS resource of the plurality of CSI-RS resources is associated with one or more corresponding TCI states as indicated by the first CSI-RS triggering state. A first CSI-RS resource of the plurality of CSI-RS resources is associated with a first plurality of TCI states as indicated by the first CSI-RS triggering state.

Abstract: A UE configured to report resources, such as beams, to a base station may be unaware of the context or purpose for which the UE is reporting such resources. As different resources may provide different performance and/or quality when used in different contexts, the resources reported by the UE may provide lower quality and/or performance in one context relative to some other unreported resources. In order to improve resource reporting by the UE, the UE may be informed of an operational mode and/or a criteria based upon which the UE may select resources to report. The UE may report such selected resources to the base station in a group-based beam report. The base station may then configure communication with the UE based on the reported resources.

Abstract: A wireless communication system utilizes a synchronization signal block (SSB) structure to enable beam switching at higher sub carrier spacing (SCS) or uplink transmissions within an SSB. The SSB structure has a first SCS for an SSB transmission and a second SCS for a data transmission. The SSB structure is based on the first SCS and the second SCS, with the SSB structure including at least one gap between SSB symbols or between SSBs. The wireless communication system transmits or receives an SSB based on the SSB structure. A base station may transmit a downlink signal during the gap, for example, where the second SCS is much greater than the first SCS. A user equipment may transmit an uplink signal such as an acknowledgment during the at least one gap. The user equipment or the base station may perform analog beam switching during the at least one gap between SSBs.

Abstract: A configuration is disclosed to enable a UE to determine and/or prepare Rx beams prior to downlink reception in multi-TRP operation. The apparatus sends, to a first TRP, a report indicating a plurality of threshold scheduled offsets. Each threshold scheduled offset associated with a different number of TCI states. The apparatus receives, from the first TRP, DCI including a TCI and a time-offset. The TCI comprising at least one TCI state. Each TCI state indicating a Tx beam for a TRP of a set of TRPs. The set of TRPs including the first TRP. The apparatus determines at least one Rx beam based on at least one of the received TCI, the time-offset, or one or more of the plurality of threshold scheduled offsets. The apparatus receives, based on the received time-offset, a PDSCH from each TRP of the set of TRPs through the determined at least one Rx beam.

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.
