Problems solved by technology

[0005] Although the existing differential reporting scheme can reduce the bit overhead of reporting the RSRP measurement value, due to the large dynamic range of the RSRP differential value (that is, the difference between the RSRP measurement value of other beams and the reference RSRP measurement value), it still needs to be compared. bit overhead

Embodiment Construction

[0085] The existing products introduce a differential reporting scheme, although it can reduce the bit overhead of reporting the RSRP measurement value, but because the dynamic range of the RSRP differential value (that is, the difference between the RSRP measurement value of other beams and the reference RSRP measurement value) is large, so More bit overhead is still required.

[0086] The embodiments of the present invention can effectively reduce the number of bits for differential quantization without affecting system performance through differential operations on adjacent RSRP values, thereby reducing bit overhead for reporting RSRP measurement values ​​and improving system efficiency.

[0087] In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0088] In an embodiment of the present ...

Abstract

The invention relates to a method for reporting RSRP (Reference Signal Receiving Power), a terminal, a computer readable medium and a system for reporting RSRP (Reference Signal Receiving Power). Themethod includes the following steps that: a differential quantization function configured by a base station for a terminal by using RRC (Radio Resource Control ) signaling is received; differential operation is performed on adjacent RSRP measurement values based on the differential quantization function; and an operation result is reported to the base station. According to the method provided by the technical schemes of the invention, differential operation is performed on the adjacent RSRP measurement values, and therefore, the number of bits of differential quantization can be effectively reduced with system performance not affected, the bit overhead of reporting the RSRP measurement values can be reduced, and system efficiency can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for reporting RSRP, a terminal, a computer-readable medium and a system. Background technique [0002] The fifth-generation (5-Generation, 5G) communication system introduces beam scanning (Beam Sweeping) and beam management (Beam Management) due to the adoption of large-scale multiple-input multiple-output (MIMO) technology. For the downlink, the base station (gNB) sends reference signals of different beams, the user equipment (User Equipment, UE) receives the corresponding beams, completes the power measurement and according to the reporting information configured by the gNB, feeds back the power measurement values ​​corresponding to the different receiving beams to the gNB . [0003] The existing product solution supports the UE to report the power measurement value based on the beam group. The specific solution is as follows: the gNB configures the relevant informa...
