Embodiment Construction

[0050] The embodiment of the present application provides a sequence-based signal processing method, related equipment, and communication system. By determining the sequence used to satisfy 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, claims, and drawings of the present application are used to distinguish different objects, rather than to describe a specific order. Furthermore, the terms "comprising" and "having" are not exclusive. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, and may also include unlisted steps or units.

[0052] At present, in the LTE system, 4G system, 4.5G system and 5G system, the PUCCH can b...

Abstract

The present invention provides a signal processing method and device based on a sequence. A sequence used for meeting PUCCH (Physical uplink control channel) sending signals is determined, the sequence is a sequence {fn} comprising N elements, the fn shows the elements in the sequence {fn}, the determined sequence {fn} is a sequence meeting a preset condition, the N elements in the sequence {fn} are respectively mapped on N carriers to generate first signals for transmission. The determined sequence is determined to maintain the low cross correlation between the sequences when the PUCCH sending signals are used and maintain a low PAPR (Peak to Average Power Ratio) value and a CM (Cubic Metric) value so as to meet the communication application environment of employing the PUCCH sending signals.

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...
