Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure associated with a component carrier (CC) of a plurality of CCs that are aggregated. The UE may identify, based at least in part on detecting the beam failure, a CC group in which the CC and one or more other CCs, of the plurality of CCs, are included. The UE may transmit, to the BS, a beam failure recovery request (BFRQ) communication associated with the CC group. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit an indication to a base station to configure a control channel of a downlink beam in accordance with a full duplex failure detection control resource set (CORESET), wherein the full duplex failure detection CORESET is used based at least in part on the UE being associated with a full duplex communication link that includes the downlink beam and an uplink beam; and monitor a reference signal on the control channel of the downlink beam based at least in part on the full duplex failure detection CORESET in order to detect a beam failure on the downlink beam while transmitting the uplink beam, wherein monitoring the reference signal is based at least in part on a threshold that is based on one or more uplink transmission parameters. Numerous other aspects are provided.

Abstract: Various aspects and features described herein relate to methods for beam failure recovery in a SCell with assistance from a PCell. In an aspect, an apparatus (e.g., a UE) may detect an SCell beam failure, and send a scheduling request in response to detection of the SCell beam failure to a base station via a PCell. The UE may receive a first message including one of an uplink grant or a trigger for an UL report from the base station via the PCell. The UE may send a second message via the PCell indicating the SCell beam failure and a preferred candidate beam associated with the SCell. The UE may receive CORESET TCI state activation from the base station via the PCell, and determine, based on the CORESET TCI state activation signal, a control channel associated with the preferred candidate beam.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a user equipment (UE) communicates with a base station on different uplink (UL) and downlink (DL) beam paths. In the example, the UE may indicate to the base station a preferred beam path to use. The UE may indicate the preferred beam path in response to an explicit request from the base station or without an explicit request. The use of different UL/DL beam paths allow beam paths which avoid interference from a user of the UE to be used.

Abstract: An apparatus, method, and a computer-readable medium for wireless communication are disclosed. The method including identifying one or more potential times for beam switching within a payload of a symbol. The method also includes determining whether to switch a transmit beam early, a switching configuration, and a switching time based on the one or more potential times for beam switching. The method further includes switching the Tx beam early using the switching configuration and the switching time if deciding to switch the Tx beam early.

Abstract: The present disclosure relates to transmitting and receiving improved monitoring reports. A base station can configure a user equipment (UE) to monitor a channel/signal on multiple beams. The base station can transmit the multiple beams to the UE, which are at different time periods in a monitoring window. The UE can then monitor the multiple beams within the monitoring window and determine a monitoring report. The UE can then transmit the monitoring report to the base station, wherein the monitoring report indicates a subset of multiple beams as being more or less suitable for communication. The base station can also indicate that it will stop transmitting one or more beams and then stop transmitting the beams. If the UE does not send the report, the base station can continue to transmit the multiple beams.

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.

Abstract: An apparatus may determine a beam configuration for a data transmission that includes at least one code block in a first resource block. In certain aspects, the at least one code block may include a first set of bits and a second set of bits. In certain aspects, the beam configuration may include a first beam in a first beam direction that may be used to communicate the first set of bits of the at least one code block in a first set of symbols of the first resource block and a second beam in a second beam direction that is used to communicate the second set of bits of the at least one code block in the second set of symbols of the first resource block. The apparatus may transmit signaling that indicates the beam configuration for the data transmission in the first resource block to a UE.

Abstract: The present disclosure provides techniques that may be applied, for example, for determining phase tracking reference signal (PT-RS) patterns/configurations. As described herein, PT-RS may be mapped to a symbol based, at least in part, on one or more symbols in which a PT-RS is expected to be punctured due to a collision with at least one of time or frequency resources allocated to another signal or to another wireless device, a MCS, and/or an expected PT-RS density.
