Abstract
A method for wireless communication at a UE and related apparatus are provided. In the method, the UE receives, from a network entity, a resource configuration including a set of communication resources for one or more CSI-RSs and one or more SRSs; and communicates with the network entity on the one or more CSI-RSs and on the one or more SRSs. A set of SRS beam weights used for communicating on the one or more SRSs is based on at least one CSI-RS of the one or more CSI-RSs, or a set of CSI-RS beam weights used for communicating on the one or more CSI-RSs is based on at least one SRS of the one or more SRSs prior to the one or more CSI-RSs in a resource sequence.
Claims29
An apparatus for wireless communication at a user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
- receive, from a network entity, a resource configuration including a set of communication resources for one or more channel state information-reference signals (CSI-RSs) and one or more sounding reference signals (SRSs);
- transmit, to the network entity in response to the resource configuration, an adequacy indication that indicates whether the set of communication resources meets a condition for performing a beam refinement process;
- and
- communicate, with the network entity in response to the adequacy indication indicating the set of communication resources meeting the condition, on the one or more CSI-RSs and on the one or more SRSs, wherein at least one of:
- a set of SRS beam weights used for communicating on the one or more SRSs is based on at least one CSI-RS of the one or more CSI-RSs, or
- a set of CSI-RS beam weights used for communicating on the one or more CSI-RSs is based on at least one SRS of the one or more SRSs prior to the one or more CSI-RSs in a resource sequence.
