Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and including disjoint segments of resource blocks (RBs). The downlink control information may be located at least partially within a first segment of the disjoint segments and a second segment of the disjoint segments may be exclusive of the downlink control information. The downlink control information may include a grant of a set of resources for a downlink shared channel that overlaps with the CORESET. The UE may determine a rate matching operation for the wideband DMRS for a downlink shared channel for portions of the set of resources that overlap with the second segment of the disjoint segments, and receive the downlink shared channel on the set of resources according to the determined rate matching operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a base station by performing an initial access procedure within an initial access bandwidth that contains control channel resources. The UE may receive a configuration of a downlink bandwidth part (BWP) following the initial access procedure, and may determine that the downlink BWP fully contains the initial access bandwidth. In some cases, the UE may make the determination based on an indication sent from the base station. For instance, the indication may be provided as part of one or more control channel configurations transmitted to the UE. Based on determining that the downlink BWP fully contains the initial access bandwidth, the UE may monitor for control information in the downlink BWP using control channel resources in the downlink BWP that correspond to control channel resources used in the initial access bandwidth.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a wireless device may include determining a rate matching configuration for a first channel (e.g., an uplink channel) associated with a second channel (e.g., a downlink channel). A wireless device may determine rate matching resources of an uplink channel based on the rate matching configuration. The wireless device may determine rate matching resources of a downlink channel based on the rate matching configuration. The wireless device may transmit a first message on the uplink channel or the downlink channel, respectively, where the transmitted channel includes the rate matching resources. The wireless device may receive a reference signal on one or more resources of the downlink channel or the uplink channel, respectively, where the one or more resources of the respective channel correspond to the rate matching resources on the transmitted channel.

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 user equipment (UE) may receive an indication of a configuration for a control resource set (CORESET) of a shared radio frequency spectrum carrier. The UE may identify a bitmap included in the configuration. Each bit in the bitmap may be associated with a respective control resource block group. The UE may identify, based at least in part on a value for each bit in the bitmap, one or more control resource block groups that are included in the CORESET. The UE may monitor for downlink communications in the one or more control resource block groups. Numerous other aspects are provided.

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.
