Abstract

The invention provides a PUCCH frequency hopping implementation method and device, and user equipment. The method comprises the following steps: determining a base sequence number adopted on a symbolin a time slot according to the time slot number, a symbol index, and the symbol length of a PUCCH format 0 or a PUCCH format 1 or the uplink symbol length in the time slot; and performing frequency hopping between the time slots or frequency hopping in the time slots and between the time slots according to the determined base sequence number. According to the invention, the base sequence frequency hopping of the PUCCH format 0 or the PUCCH format 1 can be realized in the NR.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a PUCCH frequency hopping implementation method, device and user equipment. Background technique [0002] The frame structure diagram of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) NR (New Radio, new air interface) system is as follows figure 1 As shown, in a radio frame with a length of 10 ms in the time domain, each radio frame is divided into 10 subframes with the same size and a length of 1 ms. Due to the difference in subcarrier intervals, each subframe can include multiple time slots. Each time slot consists of a certain number of symbols, and the number of symbols is determined by a CP (Cyclic Prefix, cyclic prefix) type. [0003] PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) is an uplink physical channel in the NR system, which carries uplink control information. The original intention o...
