Abstract
Techniques for selecting the number of sounding reference signal (SRS) resources to be used by a user equipment (UE) operating in a wireless communications system are provided. The UE determines a degree of partial beam correspondence of the UE and compares the degree to a threshold amount of partial beam correspondence support of the UE. In response to the comparison, UE selects a number of sounding reference signal (SRS) resources to request from a network node and sends a SRS resource request message to the network node to request the selected number of SRS resources.
