Problems solved by technology

Among the five formats, the proportion of symbols occupied by DMRS in PUCCH formats 1 to 4 is larger, that is, the overhead of DMRS is larger. In some scenarios, for example, the data volume of Uplink Control Information (UCI) is relatively large. Or, in the scenario where the uplink coverage is limited, the high overhead of DMRS will lead to a decrease in the uplink communication efficiency of the communication system

Abstract

The invention relates to a method and device for determining uplink transmission resources of a demodulation reference signal and a computer readable storage medium, and belongs to the technical fieldof communication. The method comprises the following steps: determining symbols occupied by a physical uplink control channel PUCCH in N continuous time slots, wherein N is a positive integer; in thesymbols occupied by the PUCCH, determining a second symbol set of symbols occupied by a demodulation reference signal DRMS, wherein the number of symbols in the second symbol set is smaller than thenumber of symbols in the first symbol set, and the first symbol set is determined according to the format of the PUCCH, the number of symbols occupied by the PUCCH and the distribution mode of the symbols occupied by the DMRS corresponding to the format of the PUCCH. The method can improve the uplink communication efficiency.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for determining uplink transmission resources for demodulation reference signals. Background technique [0002] A demodulation reference signal (Demodulation Reference Signal, DMRS) is used for demodulation of uplink and downlink data, and a DMRS in a physical uplink control channel (Physical Uplink Control Channel, PUCCH) is mainly used for demodulation of uplink data. [0003] In the new radio interface (New Radio, NR) technology, there are five formats of PUCCH. Among the five formats, the proportion of symbols occupied by DMRS in PUCCH formats 1 to 4 is relatively large, that is, the overhead of DMRS is relatively large. In some scenarios, for example, the data volume of Uplink Control Information (UCI) is relatively large. Or, in a scenario where the uplink coverage is limited, the high overhead of the DMRS will lead to a decrease i...
