SRS for Beam Management
SRS for Uplink Beam Management
SRS resource set used for uplink beam sweeping, beam determination, and beam failure recovery.
Technical Explanation
Configured with usage 'beamManagement', multiple SRS resources are transmitted across different spatial transmit filters (analog beams). The gNodeB measures the received signal power (SRS-RSRP) on each beam to select the optimal uplink beam pair for PUSCH and PUCCH.
Key Functions
- Performs uplink analog and digital beam sweeping
- Measures SRS-RSRP to select optimal uplink transmit beams
- Enables beam failure recovery and beam alignment in FR2
