The second communicating node device is configured, such as UE or the second communicating node device receive matching for high-rise (higher layers)
It sets, UE is also referred to as configured by high-level signaling.
It is proposed in the research of LTE-A version 10 (LTE-A Release 10): in uplink communication, it should using non-pre-
The SRS of coding, it may be assumed that the proprietary SRS of antenna, and precoding is then carried out to the reference for demodulation signal DMRS of PUSCH.First
Communication node can estimate the original CSI of uplink by receiving non-precoded SRS, and not have passed through the DMRS of precoding then not
The first communication node can be made to estimate the original CSI of uplink.At this point, when UE sends non-precoded SRS using multiple antennas, often
The resource of SRS required for a UE can all increase, and also result in decline in system with the UE quantity of concurrent multiplexing.UE can lead to
High-level signaling (also referred to as triggering by trigger type 0) or Downlink Control Information are crossed (also referred to as by trigger type
1 triggering) both triggering modes send SRS, and it is period SRS based on high-level signaling triggering, based on Downlink Control Information triggering
