For example, the UE receives a first indication indicating a same quasi co-location (QCL) mapping for multiple receive beams corresponding to a group of transmit and receive beam pairs from a network entity. Transmit and receive beam pairs are different from each other and grouping of the transmit and receive beam pairs is based on a distance between the UE and the network entity. The UE selects one of the multiple receive beams corresponding to the group of transmit and receive beam pairs, based on the distance between the UE and the network entity. ## Claims ### Claim 1 An apparatus for wireless communications by a user equipment (UE), comprising: a memory comprising instructions;
