Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive one or more downlink control information (DCI) transmissions including a plurality of transmit power control (TPC) commands. The plurality of TPC commands may relate to an uplink channel transmit power for a plurality of uplink beam-pairs. The wireless communication device may determine the uplink channel transmit power for the plurality of uplink beam-pairs based at least in part on the plurality of TPC commands. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a first sub-band and a second sub-band of a system bandwidth for communication with a user equipment (UE). The base station may determine a spatial quasi co-location (QCL) relationship between the first sub-band and the second sub-band and may transmit signaling to the UE that indicates the determined spatial QCL relationship. Upon receiving the signaling, the UE may derive, based on the indicated spatial QCL relationship, spatial parameters (e.g., beam width, pointing angle, etc.) for communication with the base station via the second sub-band. The spatial parameters may be derived based on spatial parameters used for reception of a downlink transmission from the base station via the first sub-band. Subsequently, the UE may communicate with the base station via the second sub-band using the derived spatial parameters.

Abstract: The present disclosure, for example, relates to one or more techniques for scaling the bandwidth of a carrier. Available sub-channels of an unlicensed radio frequency spectrum band may be determined, and the available sub-channels may be included in the carrier. The available sub-channels may be adjacent or non-adjacent sub-channels. The bandwidth of the carrier may be determined according to which sub-channels are included in the carrier. In this way, the bandwidth of the carrier may be scaled according to the available sub-channels in the unlicensed radio frequency spectrum band.

Abstract: A base station may transmit a quasi-collocation (QCL) relationship indication to a user equipment (UE) that indicates different QCL groups (e.g., QCL relationships corresponding to different port groups). The QCL relationship indication may include a tuple of transmission configuration indication (TCI)-states, TCI-states configured with TCI-state-sets, or multiple TCI-states indicated via an extended media access control (MAC) control element (CE). The QCL relationship indication may indicate a QCL relationship between one or more port groups of a first reference signal set and a plurality of port groups associated with a target reference signal. For example, the QCL relationship indication may indicate two QCL groups, where each QCL group includes a QCL relationship between a reference signal resource and a port group associated with a target reference signal. Using QCL group information, the UE may perform channel estimation for demodulating target reference signals, using the QCL antenna port group.

Abstract: Methods, systems, and devices for wireless communication are described that support overriding a beam monitoring pattern for control channel transmissions based on channel conditions between a user equipment and a base station. A base station may select a beam monitoring pattern for transmitting control channel transmissions, which may include a pattern in which two or more beams are used for control channel transmissions. In the event that a first beam of the beams used in the beam monitoring pattern meets certain metrics, the use of one or more additional beams according to the beam monitoring pattern may be overridden and transmissions continued using the first beam. The metrics for continuing use of the first beam may include channel quality metrics, a number of consecutive successful transmissions using the first beam, one or more other metrics, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a remaining minimum system information control resource set (RMSI CORESET) monitoring configuration based at least in part on information received by the UE in a first frame; and monitor, during a second frame and based at least in part on the RMSI CORESET monitoring configuration, for an RMSI CORESET based at least in part on a synchronization signal block (SSB), associated with the RMSI CORESET, that is received in the first frame. Numerous other aspects are provided.

Abstract: Transmission configuration indication (TCI) states may be used to indicate beam switching for data beams and/or control beams. A total set of TCI states may be divided into subsets of TCI states. TCI states conveyed via downlink control information (DCI) may thus act as beam switching indications depending on which subset a conveyed TCI state resides. A base station may transmit an indication that such DCI based control beam switching is enabled. Based on whether TCI state (e.g., included in DCI) belongs to a first subset of TCI states or a second subset of TCI states, a wireless device (e.g., that receives the DCI) may trigger a beam switching operation. Beam switching operations may include data beam switching or both data beam switching and control beam switching. The UE may then receive a downlink control channel and a downlink data channel based on the triggered beam switching operation.

Abstract: Methods, systems, and devices for wireless communication are described. Uplink resources may be allocated for transmissions of beam recovery messages. For example, a user equipment (UE) communicating in a system that supports beamformed transmissions may receive a configuration for resources from a base station, where the resources may be used for beam recovery signaling. The UE may identify a beam failure on one or more active beams used to communicate with the base station, and the UE may transmit a beam recovery message to the base station. In such cases, the beam recovery message may be transmitted according to the configuration received from the base station such that the beam recovery message is transmitted using the beam recovery resources. In some cases, the configuration may be received at the UE via radio resource control (RRC) signaling or via a system information broadcast from the base station.

Abstract: Systems and methods herein increase the throughput and decreases the collisions of transmitted resource element group (REG) bundles. Prior to transmitting a PDCCH comprising REG bundles, one or more processors perform a multi-component interleaver process that diversifies and randomizes the sequence of the REG bundles while also supporting CORESETs having different symbol lengths. In embodiments, the multi-component interleaver diversifies a virtual sequence of REG bundles using a block interleaver and then uses a randomizer interleaver to randomize the output sequence of the block interleaver. The diversified and randomized output sequence of REG bundles may be the physical channel sequenced of the REG bundles. The physical channel sequence of REG bundles is diversified and randomized such that the physical sequence increases throughput and decreases the collisions of transmitted REG bundles. Other aspects are claimed and described.
