Abstract: An electronic device having multiple antenna groups for data communication may determine a temperature of a first antenna group and determine a power gain of a second antenna group. The electronic device may communicate using the second antenna group in response to determining that the temperature of the first antenna group exceeds a temperature threshold and the power gain of the second antenna group exceeds a gain threshold. In some embodiments, the electronic device may receive communication link preferences, determine an antenna group that is disposed outside of thermal hotspots of the electronic device, and determine a beam that enables the communication link preferences via the antenna group. The electronic device may then transmit or receive data via the antenna group by forming the beam.

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: A user equipment (UE) is configured to determine a probability metric for a likelihood of a beam failure event at the UE, implement a beam management power saving scheme based on the probability metric and process a portion of network scheduled beam recovery resources within a time window. A UE may also be configured to generate a radio link monitoring (RLM) block error rate (BLER) metric associated with a beam, determine that the RLM BLER metric is below a threshold value and disable beam failure detection (BFD) and candidate beam detection (CBD) procedures at the UE in response to determining that the RLM BLER metric is below the threshold value.

Abstract: Methods and devices for allocating power among a plurality of circuits in a communication device, including determining a power budget for allocating to the plurality of circuits from a power supply information; receiving an activity status from a first circuit of the plurality of circuits; determining a first power value based on the activity status; deriving a second power value based on the first power value and the power budget; and allocating power to one or more remaining circuits of the plurality of circuits based on the second power value.
