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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The method generally includes receiving, from a network entity, signaling indicating a transmission configuration indictor (TCI) state, determining a default quasi-co location (QCL) parameter based on the TCI state for communication via a first cell of a cross-carrier scheduling protocol, and communicating with the network entity based on the default QCL parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information identifying one or more control channel monitoring span capabilities. The UE may receive, from the base station, information identifying a plurality of control channel monitoring occasions. The UE may generate a bitmap based at least in part on the plurality of control channel monitoring occasions. The UE may determine, in accordance with the bitmap and based at least in part on the information identifying the one or more control channel monitoring span capabilities, a span pattern indicating one or more locations of one or more spans in a slot. 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, from a base station (BS), information identifying a core resource set (CORESET) for one or more shared radio frequency spectrum channels. The CORESET may be configured into a plurality of resource blocks based at least in part on a resource block granularity associated with the one or more shared radio frequency spectrum channels. The UE may communicate with the BS using the CORESET. Numerous other aspects are provided.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive an indication of a bandwidth part (BWP) switch for a secondary cell and to transition between an active state and a dormant state for the secondary cell based on the indication of the BWP switch.

Abstract: Certain aspects of the present disclosure provide techniques for reference signal monitoring and transmission for remote interference management. In some cases, an aggressor base station decides to monitor for reference signals (RSs) transmitted from at least one victim BS, for example, regardless of an amount of interference from at least one remote BS detected by the first base station and participating in a remote interference mitigation (RIM) process based on the monitored RS. In some cases, a first BS transmits reference signals (RSs) as part of a remote interference mitigation (RIM) process, in response to a determination that it is an aggressor BS whose downlink transmissions possibly interfere with reception of uplink transmissions by at least one remote BS, a victim BS whose reception of uplink transmissions are possibly interfered with by downlink transmissions from the at least one remote BS, or both an aggressor BS and a victim BS.
