Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform path-loss estimation to support uplink transmit power control. The UE may perform path-loss estimations on path-loss reference signals configured by a base station. In some cases, the base station may update (e.g., activate, deactivate, or both) particular path-loss reference signals using a medium access control (MAC) control element (CE). The UE may determine which path-loss reference signal or signals to use for path-loss estimation based on one or more techniques. For example, the UE may filter path-loss measurements over a time duration or may use a single, unfiltered path-loss measurement for path-loss estimation. Additionally or alternatively, the UE may receive deactivated path-loss reference signals (e.g., for a set amount of time or for any amount of time) or may refrain from receiving deactivated path-loss reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a beam failure recovery period, that a configured control resource set at least partially overlaps with a beam failure recovery control resource set. The UE may configure, based at least in part on the at least partial overlap, a receive beam to receive the beam failure recovery control resource set. The UE may receive a control signal over the beam failure recovery control resource set during the beam failure recovery period.

Abstract: Aspects described herein relate to transmitting a set of downlink reference signals corresponding to a set of uplink beams, receiving, from a user equipment (UE) and based on measuring at least one of the set of downlink reference signals, an indication to use a separate uplink beam that is different from a downlink beam for transmitting uplink communications, configuring, based on the indication, the UE with the downlink beam and the separate uplink beam, and receiving, from the UE, uplink communications based on the separate uplink beam.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for using different configurations for downlink or uplink transmissions associated with different transmission configuration indication (TCI) states (e.g., transmitted on different beams). In one example, a base station may use different configurations for downlink transmissions to a user equipment (UE), and the base station may indicate the different configurations to the UE. For instance, the base station may transmit downlink control information (DCI) indicating a baseline configuration and other configurations as a delta of the baseline configuration. In another example, a base station may dynamically indicate a timing advance to a UE (e.g., in DCI or flow control feedback) for an uplink transmission from the UE associated with a TCI state, and the UE may use the dynamically indicated timing advance for uplink transmissions associated with the TCI state.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for training a beam for multiple component carriers (CCs) for concurrent communications in a wireless communications system associated with limited user equipment (UE) capabilities. The beam training may improve a receive or transmit beam for two or more CCs as a group that share an RF chain. The UE may receive, via a first receive beam, a first reference signal on a group of CCs over a first symbol. The UE may also receive, via a second receive beam, a second reference signal on the group of CCs over a second symbol. The UE may select a receive beam for a subsequent communication based on determining a value of a parameter for each of the first and the second receive beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, information identifying a secondary cell group including a plurality of secondary cells. The user equipment may perform, after detecting a beam failure with a secondary cell of the secondary cell group, a beam failure recovery action associated with the secondary cell group. 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 identify one or more candidate beams available for communication between the UE and a BS to replace another beam that is configured for communicating between the UE and the BS. The UE may transmit, based at least in part on identifying the one or more candidate beams, a communication that includes a new beam information (NBI) field and/or contents of the NBI field. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a first base station using a first antenna array of a set of antenna arrays of the UE. The UE may receive, from the base station, an indication that the UE is to use a second antenna array of the set of antenna arrays to transmit a random access signal. The UE may transmit, to the first base station or a second base station, the random access signal using the second antenna array based on the received indication. The UE may transmit the random access signal to the first base station as part of determining an updated timing advance (TA) value for the second antenna array. The UE may transmit the random access signal to the second base station as a part of initial access or handover.

Abstract: Aspects of the disclosure relate to mechanisms for mapping a physical downlink control channel (PDCCH) across multiple transmission configuration indication (TCI) states. In some examples, the PDCCH may then be encoded using a common mother polar code for each of a first set of control channel elements (CCEs) mapped to a first TCI state and a remaining set of CCEs mapped to a second TCI state. First and second portions of the encoded PDCCH may then be transmitted, such that the first portion includes the first set of CCEs, and the second portion includes the remaining set of CCEs.
