    Abstract: Methods, systems, and devices for wireless communications are described. Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support methods for selection of antenna arrays and beamforming feedback. In some cases, a user equipment (UE) may monitor for an antenna blockage condition at the UE and may select a set of antenna arrays for the UE for communications between the UE and a network entity based at least in part on whether the antenna blockage condition is detected, the set of antenna arrays selected from a multiple predetermined sets of antenna arrays of the UE. Additionally, the UE may transmit, to the network entity, a message indicative of whether the antenna blockage condition is detected and may communicate with the network entity using the set of antenna arrays in accordance with whether the antenna blockage condition is detected.

  • Patent number: 12183989
    Abstract: A beamforming apparatus (10) performs beamforming via a plurality of antenna elements (12) by using per-branch sign reversal circuits (16) that approximate the per-branch phase values associated with a particular beam direction or shape by selectively reversing or not reversing the polarities of the individual branch signals (18). Eliminating continuous-valued or high-resolution phasing control from the branch circuits (14) that are fed into or from the respective antenna elements (12) simplifies the branch circuitry, thereby reducing the physical space needed for the branch circuits (14) and reducing loss and noise within the branch circuits (14). Further, operating the plurality of antenna elements (12) as two or more groups (24) and controlling the differential phase between the groups (24) advantageously reduces the errors arising from the approximation of the per-branch phase values.

  • Patent number: 12177853
    Abstract: Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal (200), a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS), whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an “SRS Transmission Execution Rule” and the reception status of trigger information.
