Description
Technical field
The present invention relates to the communications field, in particular to the processing method and the relay station of a kind of cooperation multiple-input and multiple-output (Collaborative Multiple Input Multiple Output abbreviates Co-MIMO as).
Background technology
In follow-on broadband wireless communication network, solving presence of intercell interference in the cordless communication network becomes a key factor that improves user terminal (User Terminal abbreviates UT as) throughput and average user terminal throughput in the sub-district.Having relay station (Relay Station, abbreviate RS as) junction network in, the presence of intercell interference that effectively solves between base station, relay station and the user terminal thereof of base station (Base Station abbreviates BS as), relay station and affiliated user terminal thereof and adjacent sub-district will face the challenge equally.
In junction network, because relay station can be used as special user's terminal of institute's slave base stations, simultaneously, relay station self again can be the same with relay station, after slave base stations obtains running time-frequency resource, allow the access of user terminal, forming one is the junction network of the base station covering at center with the relay station.Therefore, solve the interference problem between base station and relay station, relay station and other relay stations, most important for the throughput and the average user terminal throughput that improve cell edge and relay station edge customer terminal.
At present, in IEEE 802.16j, IMT-Advanced, WINNER, all propose to adopt methods such as interference randomization, interference coordination, interference eliminated to solve the problem of presence of intercell interference.But,, must measure efficiently and accurately the interference in the system in order to reach this purpose.In order to address this problem, all kinds of different technology are at third generation partner program (3rd Generation Partnership Project, abbreviate 3GPP as), discussed widely in the standardization bodies such as Institute of Electrical and Electronics (Institute of Electrical and Electronics Engineers abbreviates IEEE as) 802.16e.Typical example be on user terminal, comprise power control, flexibly frequency reuse, grand diversity, have presence of intercell interference randomization of interference eliminated or the like.These technology can be used to improve multiple-input and multiple-output (Multiple Input Multiple Output, abbreviate MIMO as) performance, and then effectively improve peak data rate, average cell throughout, Cell Edge User throughput, but, be cost normally with average sector throughput loss or the receiver complexity that increases.
Collaboration MIMO (Collaborative Multiple Input Multiple Output, abbreviate Co-MIMO as) be the key technology of effective solution peak data rate of 3GPP Long Term Evolution (Long Term Evolution abbreviates LTE as) proposition, average cell throughout, Cell Edge User throughput.Its thought is to unite MIMO between a plurality of cooperative base station on identical Radio Resource (Collaborative BS abbreviates CBS as) and a plurality of user terminal to send and receive.Similar techniques is also proposed by a lot of companies among the IEEE802.16m, for example, the base station collaboration that Mitsubishi (Mitsubishi) proposes, the Co-MIMO that Alcatel Shanghai Bell (Alcatel Shanghai Bell) proposes, the network MIMO that Alcatel-Lucent (Alcatel Lucent) proposes and Korea S's electronics and Academy of Telecom Research (Electronics and Telecommunications Research Institute, ETRI) Co-MIMO of Ti Chuing etc.The advantage of Co-MIMO is that the interference of minizone and noise signal can be converted to effective signal by the minizone cooperation way uses, particularly for the user of cell edge, and throughput gain even can reach 100%.
