Embodiment Construction

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0063] The PUCCH (Physical uplink control channel, physical uplink control channel) of 5G (5th-Generation, fifth-generation mobile communication technology) NR (New Radio, new air interface) carries the uplink control information from the user equipment to the 5G base station gNB. Among them, 3GPP The protocol defines five PUCCH formats, which are shown in Table 1 below:

Abstract

According to the PUCCH processing method and device provided by the invention, the method comprises steps of acquiring and transmitting the PUCCH frequency domain data and the AGC factor of the current time slot according to an OFDM symbol sequence or an RB sequence; when a user of PUCCH format2 / 3 / 4 exists in the OFDM of the PUCCH, extracting a DMRS of format2 / 3 / 4; extracting the frequency domaindata of format0 / 1 and the DMRS of format1 from the RB of the PUCCH; estimating according to the DMRS of format2 / 3 / 4; according to a channel estimation result, performing channel equalization on format2 / 3 / 4 according to the RB of the PUCCH; and carrying out RB-level processing is carried out on the format0 / 1 according to the frequency domain data of the format0 / 1 and the DMRS of the format1, so that PUCCH processing processes of five PUCCH formats can be supported at the same time, the processing delay is reduced, and transmission processing is facilitated.

Description

technical field [0001] The present invention relates to the technical field of data communication, and more specifically, to a PUCCH processing method and device. Background technique [0002] The PUCCH (Physical uplink control channel) of 5G NR carries the uplink control information from the user equipment to the 5G base station gNB. Five PUCCH formats are defined in the 3GPP protocol. [0003] At present, the receiving process of PUCCH needs to go through steps such as digital front end, channel estimation, AGC factor compensation, channel equalization, and signal demodulation. PUCCH users in five formats are scheduled. The position of the starting RB for user scheduling is different, and the starting OFDM symbol is different, which will cause the distribution of PUCCH pilot symbols in a time slot to become very complicated. Among them, the PUCCH uses the pilot signal to estimate the transmission characteristics of the channel. For the PUCCH formats format 2, format 3 an...
