Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) to provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier. The UE may monitor control channel occasions, to receive wireless communications from a base station. For example, the UE may receive downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The DCI messages may include an indication of a timing offset for HARQ feedback for the multiple PDSCH. In some examples, the UE may be configured to receive multiple DCI messages and order the DCI messages based on component carrier indices or a PDCCH occasion, or both. The UE may then determine a slot to transmit HARQ feedback for the multiple PDSCH based on an indication in a latest DCI message identified according to the ordering.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine to configure a user equipment (UE) to operate in a transmission/reception point (TRP) mode, wherein the TRP mode is a single-TRP mode or a multi-TRP mode. The BS may configure the UE to operate in the TRP mode based at least in part on a bandwidth part (BWP) switch or a trigger to switch between the multi-TRP mode and the single-TRP mode within a BWP. Numerous other aspects are provided.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that indicates a transmission parameter associated with a random access response (RAR) type; transmit a random access message associated with the RAR type; use the transmission parameter to obtain a physical downlink control channel (PDCCH) communication that schedules a physical downlink shared channel (PDSCH) communication that includes a RAR in a medium access control protocol data unit of the PDSCH communication; and obtain or refraining from obtaining the PDSCH communication based at least in part on whether the PDCCH communication is successfully obtained using the transmission parameter. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message to a base station, the UE capability message including an indication of a UE type, the UE type associated with at least one of a reduced bandwidth, or a reduced number of antennas, or a combination thereof, for the UE. The UE may monitor, based at least in part on a control resource set that is based at least in part on the UE type, a control channel for a downlink grant for downlink resources. The UE may receive, based at least in part on the monitoring, a grant identifying the downlink resources for communicating with the base station. The UE may communicate with the base station using the identified downlink resources.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved RAR decoding performance and resource utilization efficiency in a RACH procedure. A PDCCH with common search space encodes a DCI with configuration information that schedules separate PDSCHs for different UEs/UE groups. When sending a RAR message, the PDCCH includes a DCI with a configuration field to signal multiple DMRS resources with corresponding PDSCH. Each sub-field of the configuration field may include one or multiple bits. When one bit per sub-field, the bit is a flag that when asserted leads the UE to blind decode the PDSCH associated with that DMRS resource. When multiple bits, it includes a flag field as well as one or more bits that include least significant bits of a UE identifier (or group identifier). The UE locates its identifier (or group identifier), and limits decoding to that PDSCH with corresponding DMRS resource.
