  • Patent number: 12040937
    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a user equipment (UE) detects a beam failure of a first beam for a first component carrier (CC) based on a link quality associated with the first beam for the first CC. The first CC and a second CC are within a same group of CCs. The UE initiates one or more beam failure recovery operations associated with any CC within the same group of CCs as the first and second CCs based on a determination of a beam failure of a second beam for the second CC. The determination is based on the detection of the beam failure for the first CC and based on the first CC and the second CC being within the same group of CCs.

  • Patent number: 12022476
    Abstract: This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.

    Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may transmit, to a second UE, first control information indicating a first transmission configuration indicator (TCI) state for use in sidelink communications between the first UE and the second UE. The first UE may receive, from the second UE, second control information indicating a second TCI state for use in sidelink communications between the first UE and the second UE, where a first application time of the first TCI state conflicts with a second application time of the second TCI state. The first UE may select, in accordance with one or more rules for resolving sidelink TCI state conflicts, one of the first TCI state or the second TCI state as a selected TCI state. Accordingly, the first UE may communicate with the second UE in accordance with the selected TCI state.
