Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication identifying a physical downlink control channel (PDCCH) monitoring location associated with receiving a next downlink control information (DCI) communication. The user equipment may monitor in the PDCCH monitoring location based at least in part on the indication. The indication may be valid at least until the PDCCH monitoring location, irrespective of an amount of time between receiving the indication and monitoring in the PDCCH monitoring location. 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 transmit, to a base station via an uplink control channel, a negative acknowledgement (NACK) when a downlink shared channel transmission is not successfully received at the UE. The UE may receive, from the base station and based at least in part on the NACK, one or more channel state information reference signals (CSI-RSs) at one or more semi-persistent CSI measurement occasions. The UE may transmit, to the base station, one or more CSI reports at one or more semi-persistent CSI reporting occasions corresponding to the one or more semi-persistent CSI measurement occasions, wherein the one or more CSI reports include one or more channel measurements based at least in part on the one or more CSI-RSs. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling from a base station indicating a configuration for layer one (L1) measuring and reporting of downlink reference signals received from a non-serving cell. The UE may receive a set of downlink signals (e.g., a set of synchronization signal blocks (SSBs) or a set of channel state information reference signals (CSI-RSs)) from a base station associated with the non-serving cell. In response to receiving the downlink reference signals, the UE may determine channel information including of a set of channel metrics based on measuring the downlink reference signals. The UE may then transmit an L1 report to the base station of the serving cell indicating the channel information.

Abstract: Aspects relate to mechanisms for wireless communication devices to utilize transmission configuration indication (TCI) field invalidation after PDSCH beam setting. A user equipment (UE) detecting a beam failure on a connected beam. The UE transmits a beam failure recovery request. The beam failure recovery request includes an indication of a candidate beam. The UE receives a first message including a beam failure recovery response and a second message including downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH). The UE applies the candidate beam to the PDSCH when the second message is received at least a predetermined number of symbols after receiving the first message.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a sensor included within the UE, information associated with a base station. For instance, the UE may receive, via a camera included within the UE, an image of the base station. In some cases, the information associated with the base station may also include environment information identifying an antenna of the base station. The UE may then perform, based on the received information, a beam management procedure to track a UE beam corresponding to a base station beam, and communicate with the base station based on the beam management procedure.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), data from one or more beam pairs of a plurality of beams at least partially concurrently; determining, by the UE, one or more signal parameters for the one or more beam pairs; determining, by the UE, one or more joint quasi co-located (QCL) indicators for the one or more beam pairs and one or more non-joint QCL indicators for the one or more beam pairs; and transmitting, by the UE, a measurement report including the one or more joint QCL indicators and the one or more non-joint QCL indicators. In another aspect, a method of wireless communication includes determining a particular beam or beams for transmitting second data based on the measurement report; and transmitting the second data using the particular beam or beams. Other aspects and features are also claimed and described.

Abstract: Aspects presented herein provide for improved measurement and management of interference for different subbands and different Tx beams for communication with the UEs. A UE may be configured to receive scheduling for communication with a base station in a first beam direction using a first subband. The UE may be configured to measure interference of a second subband for a second beam direction. The UE may be further configured to report the measured interference to the base station. A base station may be configured to schedule communication with the UE in the first beam direction using the first subband. The base station may be further configured to receive the report of interference measured by the UE on the second subband in the second beam direction.

Abstract: Apparatuses and methods for wireless communication are provided. In an aspect, a user equipment (UE) receives a DCI from a base station, the DCI including an update to a periodically-occurring scheduling, where an absolute time for the update to take effect is specified in an RRC configuration of the DCI. The UE applies the update to the periodically-occurring scheduling for communications of the UE beginning at and following the absolute time. In another aspect, the UE receives at least one downlink communication that updates a plurality of SPS or CG parameters. The UE determines an action time for the update to take effect for each parameter, where the action time is a function of a type of each parameter. The UE applies the update to each parameter for communications of the UE beginning at and following a respective action time.
