Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may switch from a first group of search space sets for monitoring a physical downlink control channel (PDCCH) to an empty group of search space sets. The UE may refrain from monitoring the PDCCH based at least in part on switching to the empty group. In some aspects, the UE may switch from a first group of PDCCH search space sets to at least one dormant group of PDCCH search space sets identified in configuration information. The UE may also process one or more PDCCH search space sets of the at least one dormant group of PDCCH search space sets based at least in part on the received configuration information. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to various apparatus, methods, and computer-readable media for providing or utilizing initial acquisition parameters for reduced-capability wireless user equipment (UEs). In one example, a wireless base station may transmit a plurality of synchronization signal blocks (SSBs), with at least one of those SSBs being designated for a set of reduced-capability UEs. The base station may further transmit a plurality of control resource sets with at least one of those control resource sets being designated for the set of reduced-capability UEs. In another example, the base station may transmit a shared SSB/control resource set configured for compatibility with both legacy UEs and reduced-capability UEs. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a beam management configuration that indicates a set of resources to be used by the UE for transmitting a plurality of reference signals, including at least one sounding reference signal (SRS) and at least one demodulation reference signal (DMRS), to be used for beam refinement during an uplink beam management occasion; and transmit, to the base station, the at least one SRS and the at least one DMRS based at least in part on the beam management configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform respective measurements of one or more demodulation reference signals (DMRSs). Each of the one or more DMRSs may be associated with a repetition of a downlink transmission. Each of the one or more DMRSs may be transmitted on a narrow beam that is located within a wide beam associated with a transmission configuration indication indicated in a grant for the downlink transmission. The UE may transmit an indication of one or more of the respective measurements. 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, based at least in part on the UE being a reduced-capability UE, control information on a reduced capability control resource set (CORESET) at least partially in a reduced capability region of a CORESET region, wherein the reduced capability CORESET is associated with a reduced configuration relative to a CORESET for a non-reduced-capability UE; and communicate in accordance with the control information. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communicating a serving cell dormancy indication field and acknowledgement. In some implementations, a wireless communication device (e.g., user equipment), may detect a physical downlink control channel (PDCCH) with a secondary cell (Scell) dormancy indication field. The user equipment can change states from an initial state to another state (e.g., a dormancy-like state to a non-dormancy like state) based on detecting Scell indicator field in the PDCCH. The user equipment may also transmit a hybrid-ARQ acknowledgment (HARQ-ACK) in response to the detecting the PDCCH with the Scell dormancy indication field. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for carrier group based multiple-input multiple-output (MIMO) layers and antenna adaptation. A method that may be performed by a user equipment (UE) includes receiving a configuration of one or more groups of component carriers (CCs) and, for each group of CCs, one or more sets of configured maximum number of MIMO layers. Each set includes a configured maximum number of MIMO layers associated with each CC in the group. The UE receives an indication of at least one of the one or more sets and determines the configured maximum number of MIMO layers associated with each CC in the corresponding group of CCs based on the indication.
