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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a wakeup signal search space (WUS-SS) set for a physical downlink shared channel (PDCCH) wakeup signal (WUS). The UE may detect the PDCCH WUS in the WUS-SS set based at least in part on monitoring the WUS-SS set. Numerous other aspects are provided.

Abstract: Methods implemented by a processor in a wireless device for detecting the presence in a network of a jammer or non-benign entity that targets physical layer channels in a communication network are disclosed. Various embodiments may determine a first signal measurement quantity based on a first physical layer communication, determine a second signal measurement quantity based on a second physical layer communication, determine a difference between the first signal measurement quantity and the second signal measurement quantity, determine whether the difference between the first signal measurement quantity and the second signal measurement quantity satisfies a threshold, determine whether a jammer or non-benign entity is present in the network in response to determining that the difference between the first signal measurement quantity and the second signal measurement quantity satisfies the threshold, and perform a mitigation operation in response to determining that a jammer or non-benign entity is present in the network.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a scheduling offset threshold corresponding to a cross-slot grant. The UE may monitor a control channel in a first slot for the cross-slot grant, the control channel having a first numerology that is different than a second numerology of a shared channel and determine a beginning slot defined in the second numerology based on interpreting the scheduling offset threshold as being defined in the first numerology or the second numerology. The UE may then enter a low power state, or communicating a data transmission, during the beginning slot based on whether the cross-slot grant is detected

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a baseline physical downlink control channel (PDCCH) monitoring capability of the UE and an enhanced PDCCH monitoring capability of the UE, where the enhanced PDCCH monitoring capability facilitates monitoring by the UE of more PDCCH monitoring opportunities per slot than the baseline PDCCH monitoring capability. The UE may report, to a base station, the enhanced PDCCH monitoring capability and also the baseline PDCCH monitoring capability. The UE may receive, based on the UE reporting the enhanced PDCCH monitoring capability, at least one control resource set configuration that includes an indication that a corresponding control resource set is configured for enhanced PDCCH monitoring. The UE may monitor the corresponding control resource set in accordance with the enhanced PDCCH monitoring capability of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a user equipment (UE) may receive a configuration message from a base station. The configuration message may configure the UE based on one or more identifiers associated with a group of UEs. The UE may determine at least one identifier based on receiving the configuration message, and may monitor a signal based on the at least one identifier. In some cases, the signal may indicate whether the UE should skip an upcoming duration associated with a discontinuous reception. The UE may then communicate with the base station, based on monitoring the signal.
