Abstract

The invention relates to a wireless communication technology and discloses a method for generating information of a relay link physical uplink control channel, which comprises the following steps: determining an orthogonal sequence corresponding to a sequence index according to the sequence index; and generating the information carried by the relay link physical uplink control channel (R-PUCCH) according to the determined orthogonal sequence. The invention further discloses a communication device, which comprises a determining unit and a generating unit, wherein the determining unit is used for determining the orthogonal sequence corresponding to the sequence index according to the sequence index; and the generating unit is used for generating the information carried by the R-PUCCH according to the orthogonal sequence determined by the determining unit. According to the scheme of the invention, the corresponding orthogonal sequence is determined according to the sequence index, and the information carried by the R-PUCCH is generated according to the orthogonal sequence, thereby enabling the information to have orthogonality and improving the performances of a relay system.

Description

Technical field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for generating relay link physical uplink control channel (Relay link Physical Uplink Control Channel, R-PUCCH) information. 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 increase 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 user equipment (User Equipment, UE) feeds back information on the Physical Uplink Control Channel (PUCCH), it uses orthogonal sequences in the time domain to introduce Orthogonality, divided into multiple sub-channels.

[0004] After the introduction of the relay technology in the LTE...
