Embodiment Construction

[0075] 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.

[0076] 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.

[0077] Currently, in LTE systems, 4G systems, 4.5G systems, and 5G systems, PUCCH can be used to tr...

Abstract

The present application provides a sequence-based signal processing method, communication device and communication system. The sequence used to transmit the signal satisfying the PUCCH is determined,The sequence is a sequence {fn}comprising 12 elements, fn refers to the elements in the sequence, and the determined sequence {fn} is a sequence satisfying a preset condition. Then, the 12 elements inthe sequence are respectively mapped to 12 sub-carriers to generate a first signal and transmit the first signal. With the sequence determined above, it is possible to maintain low cross-correlationbetween sequences while maintaining low PAPR and CM values when signals are transmitted using the PUCCH, thereby satisfying a communication application environment in which signals are transmitted using 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, communication equipment and communication system. 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 to transmit uplink control information (Uplink Control Information, UCI). Among them, 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 transmitted 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 sequence between adjacent cells has low cross-correlation. In order to...
