    Abstract: In one aspect, performing, by a wireless communication device, a non-coherent encoding operation on first data to generate a first transmission, wherein the non-coherent encoding operation encodes data independent of channel state information (CSI); and transmitting, by the wireless communication device, the first transmission, wherein the first transmission is non-coherently encoded. In another aspect, receiving, by a wireless communication device, a first transmission, wherein the first transmission is non-coherently encoded independent of channel state information (CSI); and performing, by the wireless communication device, a non-coherent decoding operation on the first transmission to decode the first transmission. Other aspects and features are also claimed and described.

    Abstract: In one aspect, a method for wireless communication includes transmitting a first message indicating a precoding matrix identifier configured to identify a particular precoding matrix for precoding by another wireless communication device for at least one future transmission; and receiving a second message indicating information about whether the particular precoding matrix was or will be used for the at least one future transmission. In another aspect, a method for wireless communication includes receiving a first message indicating a precoding matrix identifier configured to identify a particular precoding matrix for precoding by the wireless communication device for at least one future transmission; and transmitting a second message indicating information about whether the particular precoding matrix was or will be used for precoding for the at least one future transmission. Other aspects and features are also claimed and described.

    Abstract: In some aspects, a UE may select a first type of antenna for communication with a base station based at least in part on a beam management procedure that uses an RSRP parameter determined using a downlink reference signal associated with a single antenna port; measure a CSI-RS resource for CSF, associated with multiple antenna ports, using a second type of antenna and after selecting the first type of antenna; compare a first spectral efficiency parameter associated with communicating using the first type of antenna and a second spectral efficiency parameter determined based at least in part on measuring the CSI-RS resource for CSF using the second type of antenna; and select one of the first type of antenna or the second type of antenna for subsequent communication with the base station based at least in part on comparing the first spectral efficiency parameter and the second spectral efficiency parameter.

    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: 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.
