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: 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: Aspects presented herein may enable a UE to provide HARQ feedback for multiple groups of CBs based on their associated CBG and TBG. In one aspect, a UE receives an RRC configuration for a HARQ transmission, the RRC configuration including a CBG configuration and a TBG configuration. The UE determines, based on the CBG configuration, a number of CBs for each of a plurality of CBGs for HARQ feedback. The UE determines, based on the TBG configuration, a number of TBs for each of a plurality of TBGs for the HARQ feedback. The UE transmits, to a base station, the HARQ feedback, where the HARQ feedback is based on the number of CBs for each of the plurality of CBGs and the number of TBs for each of the plurality of TBGs.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a control node may receive, from a movable relay node, a capability message indicating a set of operational parameters for the movable relay node. The control node may determine a location for the movable relay node based on the capability message and may transmit, to the movable relay node, a location message indicating the determined location. The movable relay node may change locations or reconfigure one or more relay devices (e.g., reconfigurable intelligent surfaces) of the movable relay node based on the location message. Accordingly, the control node may use the movable relay node to relay messages between the control node and a second node, which may increase the likelihood of successful communications between the control node and the second node.
