Abstract: Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The UE may measure the reference signal received power (RSRP) of each of a plurality of downlink beams during a beam sweep and modify an automatic gain control (AGC) state of the UE based on the difference in RSRP between a current downlink beam and an expected downlink beam expected to be selected by the base station for subsequent unicast downlink transmissions to the UE. In some examples, the expected downlink beam may have a highest RSRP among all of the measured RSRPs of the different downlink beams Other aspects, features, and embodiments are also claimed and described.

Abstract: A method for communication beam transition in a communication system includes sending beam information on a first communication beam, receiving a beam switch command on the first communication beam, the beam switch command requesting a transition from the first communication beam to a second communication beam, simultaneously sending and receiving information on the first communication beam and the second communication beam, and ceasing sending and receiving information on the first communication beam when transition to the second communication beam is completed.

Abstract: Certain aspects of the present disclosure provide techniques for beam management using adaptive learning. Certain aspects provide a method that can be performed by a node, such as user equipment (UE) or a base station (BS). The node determines one or more beams to utilize for a beam management procedure using adaptive learning. The node performs the beam management procedure using the determined one or more beams. In some aspects, the node uses an adaptive reinforcement learning algorithm to select beams for measurement in beam discovery procedure. The node may adaptive the beam management algorithm based on feedback associated with the beam selection, such as based on a throughput achieved using a beam pairing determined during the beam management procedure.

Abstract: Technology herein selectively adjusts the frequency with which beam scanning is performed. Systems and methods herein determine present conditions of the UE and determine whether adjusting the current frequency of beam scanning is desired. Based at least on the present conditions, the current frequency may be reduced, increased, or maintained in order to balance the use of processing resources with the instability of channels.

Abstract: Systems and methods herein remedy thermal constraints experienced by wireless communication systems operating in the millimeter wave spectrum. User equipment (UE) having a plurality of antenna subarrays controlled by respective RFICs monitor temperature gradients of respective sectors of the UE. Upon the thermal gradient of a sector reaching a temperature threshold, the UE performs thermal management steps to prevent hardware of a respective sector from damage due to overshoot.

Abstract: A method, an apparatus, and a computer-readable medium may be described in the present disclosure. The apparatus may be a user equipment. The apparatus may determine whether a number of unsuccessful repetitions associated with performance of a first type of scanning exceeds a repetition threshold. The apparatus may perform a second type of beam scanning based on the determination that the number of unsuccessful repetitions exceeded the repetition threshold.

Abstract: Various aspects described herein relate to cancelling interference in wireless communications. Energy level detection of a received signal can be performed to determine an allocation size and position corresponding to an interfering device in the received signal. An interference demodulation reference signal (DM-RS) and cyclic shift of the interfering device in the received signal can be determined. It can be determined whether to apply successive interference cancellation on the received signal, based at least in part on the allocation size and position and the DM-RS and cyclic shift, to cancel interference from the interfering device.
