Abstract: Some aspects relate to apparatuses and methods for selecting a receiving beam based on hybrid channel based beamforming and codebook based beamforming. A user equipment (UE) can determine, based on a first measurement related to signal to noise ratio (SNR) and predetermined threshold values, whether the UE is in a low SNR state. If the UE is in a low SRN state, the UE can derive an estimated channel covariance matrix RCH for channels at a set of antenna elements of the UE based on channel based beamforming (CHBF). Afterwards, a set of test beams {0, . . . Ntest−1} is selected based on the channel covariance matrix RCH, and a set of codebook measurement beams is further selected based on the set of test beams. A receiving beam is selected based on a set of measurements performed on the set of codebook measurement beams at the measurement opportunity for codebook based beamforming (CBBF).

Abstract: Techniques described herein include solutions for utilizing dual port synchronization signal block (SSB) transmissions for multiple receive (Rx) beam selection. In some aspects, a base station transmits a first SSB with a first polarization on a first antenna port, and transmits a second SSB with a second polarization on a second antenna port. The first and second SSBs may be transmitted, for example, using a first transmission reception point (TRP). A user equipment (UE) receives the first and second SSBs, and identifies one or more optimal Rx beams for multiple-input multiple-output (MIMO) communication based on the first and second SSBs.

Abstract: Apparatuses, systems, and methods for beam failure recovery based on a unified TCI framework. A UE may receive, from a base station, a configuration for a BFR procedure for a CCG. The CCG may include at least two CCs and the UE may periodically receive, from the base station, at least a first BFD RS and a first CBD RS in a first CC included in the CCG. The UE may detect, based on the first BFD RS, a beam failure in at least the first CC and send, to the base station, a BFRQ. The BFRQ may include a candidate beam selected based on at least the first CBD RS and may be sent via a PRACH or MAC CE. The UE may receive, from the base station, a BFR response and apply the candidate beam to the first CC and at least one additional CC of the CCG.

Abstract: An electronic device may receive, from a radio node, a measurement configuration associated with a wireless communication system. In response, the electronic device may perform measurements using narrow beam patterns based at least in part on a network configuration, where the narrow beam patterns are narrower than a wide beam pattern of the electronic device. Furthermore, performing the measurements using the narrow beams pattern may include performing a beam-pattern search up to the network configuration. Then, the electronic device may perform an SCell activation procedure of an SCell with the radio node. Note that the SCell activation procedure may include reporting, to the radio node, CSI of a narrow beam pattern of the SCell that is to be activated, where the narrow beam pattern is narrower than the wide beam pattern of the electronic device, and the narrow beam pattern is based at least in part on the measurements.

Abstract: A user equipment (UE) device may communicate with a wireless base station (BS). Each antenna in a phased antenna array on the UE may receive a reference signal transmitted by the BS during the beam training interval. Transceiver circuitry may measure wireless performance metric data from the reference signal. While receiving the reference signal, control circuitry may selectively activate different individual antennas, may selectively activate different subsets of antennas, or may concurrently activate all of the antennas in the array. The control circuitry may identify, based on the wireless performance metric data, a first set of the antennas in the array to that are being blocked by an external object and a second set of antennas array that are not blocked. After the beam training interval, the transceiver may use the second set of antennas to convey wireless data with the BS while the first set of antennas are disabled.
