Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for dynamically updating transmission configuration information (TCI) state and spatial relation information. For example, downlink control information (DCI) or media access control control element (MAC-CE) is used to update a large number of TCI states. As such, high efficiency, such as in terms of low overhead or usage of memory, is achieved with an increase of the upper limit of configured trigger state numbers. The DCI or MAC-CE is used to dynamically update the content in the large number of TCI states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.

Abstract: Embodiments include methods that may be performed by a processor of a mobile device and a processor of a base station for managing beam failure recovery (BFR). The processor of the mobile device may determine whether a beam failure of a communication link with a base station has occurred, determine whether contention free random access (CFRA) resources have been configured in response to determining that a beam failure has occurred, and initiate contention based random access (CBRA) in response to determining that CFRA resources have not been configured. The processor of the base station may receive from the mobile device a message initiating CBRA, determine whether a downlink beam or quasi-colocation (QCL) assumption a downlink resource of a physical random access channel (PRACH) is different from any active downlink beam or QCL assumption, and perform CBRA with the mobile device.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for updating beam information across a plurality of component carriers (CCs) via downlink control information (DCI). An exemplary method, performed by a user equipment (UE), generally includes receiving, from a network entity, a downlink control information (DCI) for an update for at least of a beam or path loss (PL) reference signal (RS) activation and applying the update across at least one of a group of component carriers (CCs) or bandwidth parts (BWPs) within the group of CCs.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a configuration for a measurement resource. In a first aspect, a method of wireless communication includes receiving a medium access control-control element (MAC-CE) or downlink control information (DCI) that indicates a configuration for a channel measurement resource (CMR) time restriction, an interference measurement resource (IMR) time restriction, or a combination thereof. The method also includes transmitting a report based on the configuration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

Abstract: Apparatus, methods, and computer program products for PHY priority for wireless communications are provided. An example apparatus may multiplex a first uplink control information transmission based on a first uplink resource and a second uplink control information transmission based on a second uplink resource that overlaps in time with the first uplink resource, at least one of the first uplink resource and the second uplink resource being for full-duplex communication. The example apparatus may determine, based on applying a multiplexing rule on the full-duplex communication, whether to use the first uplink resource associated with a first beam or the second uplink resource associated with a second beam. The example apparatus may transmit a multiplexed uplink control information transmission using a determined uplink resource based on the multiplexing rule.

Abstract: In a first aspect, a method of wireless communication includes receiving, by a user equipment (UE) from a first network entity, a multiple component carrier (CC) signaling message including multiple CC scheduling information. The method also includes receiving, by the UE from, a downlink control information transmission indicating a downlink control information indication for multiple CCs, and determining a first downlink control information parameter for a first CC and a second downlink control information parameter for a second CC based on the downlink control information indication and the multiple CC scheduling information. The method further includes receiving, from the first network entity, a first downlink transmission for the first CC based on the first downlink control information parameter, and receiving, from a second network entity, a second downlink transmission for the second CC based on the second downlink control information parameter. In other aspects, uplink transmissions may be sent.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive one or more messages scheduling a first uplink transmission over a first physical uplink control channel (PUCCH) resource on a first component carrier and a second uplink transmission over a second PUCCH resource on a second component carrier and, if the first PUCCH resource and the second PUCCH resource overlap in time, the UE 115 may transmit the first uplink transmission and the second uplink transmission using spatial relation information in accordance with a spatial relation configuration that is dedicated for selecting spatial relation information for simultaneous PUCCH transmissions on different component carriers. A network entity may configure the UE with spatial relation information for the overlapping PUCCH resources and the UE may select spatial relation information to use for the simultaneous uplink transmissions in accordance with the spatial relation configuration.
