Embodiment Construction

[0050] The embodiments of the application provide a sequence-based signal processing method, related equipment, and communication system. By determining the sequence that satisfies the PUCCH transmission signal, the low cross-correlation between the sequences can be maintained when the PUCCH is used to transmit the signal. Lower PAPR value and CM value, so as to meet the communication application environment using PUCCH to send signals.

[0051] The terms "first" and "second" in the embodiments of the present application, claims, and drawings are used to distinguish different objects, rather than to describe a specific sequence. In addition, the terms "including" and "having" are not exclusive. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, and may also include unlisted steps or units.

[0052] Currently, in LTE systems, 4G systems, 4.5G systems, and 5G systems, PUCCH can be used to tr...

Abstract

The present invention provides a sequence-based signal processing method and device, and the method comprises the steps: determining a sequence that meets the requirement of a PUCCH for transmitting asignal, wherein the sequence is a sequence {fn} of N elements, and fn is an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition; mapping N elementsin the sequence {fn} onto N subcarriers, generating a first signal and transmitting the first signal. Through the sequence determined above, the method can maintain low cross-correlation between sequences while transmitting signals using the PUCCH, maintains a lower PAPR value and CM value, thereby meeting the requirement of a communication application environment in which signals are transmittedusing the PUCCH.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular, to a sequence-based signal processing method and device. Background technique [0002] In the long term evolution (LTE) system, the physical uplink control channel (PUCCH) occupies 13 or 14 orthogonal frequency division multiplexing (OFDM) symbols in a subframe Or orthogonal frequency division multiple access (discrete fourier transform spread OFDM, DFT-s-OFDM) symbols for discrete Fourier transform spread spectrum transmission of uplink control information (UCI). Among them, PCUUH format 1a / 1b (PUCCH format 1a / 1b) is used to transmit 1-bit or 2-bit response information, and sequence modulation is used to transmit PUCCH format 1a / 1b. Generally, in an LTE system, in order to avoid PUCCH interference between two adjacent cells, it is necessary to consider that the selected sequence between adjacent cells has low cross-correlation. In order to improve the coverage of the PU...
