Abstract

The invention relates to the technical field of wireless communication and discloses a method for generating information of an R-PUCCH (Relay Link Physical Uplink Control Channel). The method comprises the following steps of: selecting an orthogonal sequence from an orthogonal sequence matrix; and generating information carried on the R-PUCCH according to the determined orthogonal sequence. The invention also discloses communication equipment. In the technical scheme provided by the embodiment of the invention, the corresponding orthogonal sequence is determined according to the orthogonal sequence matrix, and the information is carried on the R-PUCCH according to the orthogonal sequence, so that the information has orthogonality to ensure that the performance of a relay system is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for generating information of a relay link physical uplink control channel (Relay link Physical Uplink Control Channel, R-PUCCH). Background technique [0002] With the development of wireless communication services, communication systems need to support wireless communication at low cost and provide better coverage or system throughput. The relay technology can extend the coverage feedback of the cell or improve the capacity of the cell, so the relay technology has attracted more and more attention. [0003] In the existing Long Term Evolution (LTE) system, when the user equipment (UserEquipment, UE) feeds back information on the Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH), it uses an orthogonal sequence in the time domain to introduce Orthogonality, dividing multiple sub-channels. [0004] After the re...
