Abstract

The invention provides a sequence-based signal processing method and device. The method comprises the following steps: determining a sequence used for sending signals by using a PUCCH (Physical UplinkControl Channel), wherein the sequence is a sequence {fn} including N elements, fn means elements in the sequence {fn}, and the determined sequence is a sequence that satisfies a preset condition; and then respectively mapping N elements in the sequence {fn} to N sub-carriers, and generating a first signal and sending the first signal. By means of the determined sequence, the low cross-correlation between sequences can be kept when the PUCCH is used for sending the signals, and meanwhile, a lower PAPR value and a lower CM value are kept, so that the communication application environment utilizing the PUCCH to send the signals is met.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a sequence-based signal processing method and device. Background technique [0002] In a long term evolution (LTE) system, a physical uplink control channel (PUCCH) occupies 13 or 14 orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols in a subframe Or discrete Fourier transform spread spectrum orthogonal frequency division multiple access (discrete fourier transform spread OFDM, DFT-s-OFDM) symbols to transmit uplink control information (uplink control information, UCI). Wherein, the PCUUH format 1a / 1b (PUCCH format 1a / 1b) is used to transmit 1-bit or 2-bit response information, and the PUCCH format 1a / 1b is sent in a sequence modulation manner. Generally, in an LTE system, in order to avoid PUCCH interference between two adjacent cells, it is necessary to consider that the selected sequences between adjacen...
