SRS-ResourceSet.usage = antennaSwitching UE performs antenna switching in various way depending on RRC parameter setting in SRS-ResourceSet as described in 38.214 6.2.1.2. Customers may choose to purchase a GNSS antenna from SRS, or a third party, or use an existing GNSS antenna at their facility. Reference Signal for who ? The Mobile Radio Unit is a CBTC component used to provide an interface from VOBC to the ZC and the ATS. Initialize UE-specific and channel configuration structures (ue and chs) for 3 MHz bandwidth and two antennas using the default SRS configuration. Assuming channel reciprocity holds, as should be the case for TDD operation, this feature enables gNB, or 5G NR base station, to estimate CSI on secondary downlink "only" cells. The four main reference signals are the demodulation reference signal (DMRS), phase-tracking reference signal (PTRS), sounding reference signal (SRS) and channel-state information reference signal (CSI-RS). When configuring an SRS for such UL channel sounding purpose, then the "usage" parameter in the SRS resource set configuration is set to "AntennaSwitching." This name may sound confusing if full channel sounding is used (and hence no antenna switching is performed) because even in this case the usage parameter is set for "AntennaSwitching." The BGSX24MU16 RF CMOS switch is specifically designed for cellular applications (LTE, 5G) and can be applied up to 4 antennas. When a SRS is added, a representative button is added at the top of the SRS parameter group. antenna array is typically used, where the distance d between the individual antennas is the same and d ≤ λ/2.
