Description

Method, terminal, computer readable medium and system for reporting RSRP
Technical Field
The present invention relates to the field of communications, and in particular, to a method, a terminal, a computer-readable medium, and a system for reporting RSRP.
Background
A fifth Generation (5-Generation, 5G) communication system introduces Beam scanning (Beam scanning) and Beam Management (Beam Management) because it employs a massive Multiple-Input Multiple-output (MIMO) technology. For downlink, a base station (gNB) sends reference signals of different beams, and a User Equipment (UE) receives the corresponding beams, completes power measurement and feeds back power measurement values corresponding to the different received beams to the gNB according to reporting information configured by the gNB.
The existing product scheme supports UE to report power measurement values based on beam groups, and the specific scheme is as follows: and the gNB configures the relevant information of the reported power measurement values for the UE and indicates the number of the beam groups which need to be reported by the UE and the number of the power measurement values corresponding to the beams contained in each group of beam groups. When reporting the Power measurement value of the beam, the UE needs to report the gNB transmit beam ID in each beam group and a Reference Signal Receiving Power (RSRP) measurement value corresponding to a receive beam forming a beam pair with the transmit beam ID, and the RSRP measurement values are arranged in the descending order.
In order to reduce the bit overhead of reporting the RSRP measurement value, a differential reporting scheme is further introduced, and UE reports the reference RSRP measurement value corresponding to each group of beams, the difference value between the RSRP measurement value corresponding to other beams in the group and the reference RSRP measurement value, and gNB sending beam ID.
Although the existing differential reporting scheme can reduce the bit overhead of reporting the RSRP measurement value, the dynamic range of the differential value of the RSRP (i.e. the difference between the RSRP measurement value of other beams and the reference RSRP measurement value) is large, so that still more bit overhead is required.
