Abstract

The invention discloses a method of negotiating and determining an operating mode of a RN (Role Network). The method mainly comprises the steps that the RN reports a preconfigured operating mode of the RN to a DeNB (donor eNB); and the DeNB determines the operating mode of the RN according to the operating mode reported by the RN and the information of equipment capacity of the DeNB and informs the RN of the determined operating mode. The invention also disclose a system of negotiating and determining the operating mode of the RN; the system not only can ensure the operating mode of the RN and the operating mode of the RN recorded on the DeNB to be consistent when the RN is connected into the DeNB but also can avoid an unnecessary interactive negation flow, thereby effectively improving the negotiation efficiency and saving resources; meanwhile, by adopting the system, the preconfigured operating mode inappropriate for the DeNB can be modified; and the system is simple, flexible and reliable.

Description

technical field

[0001] The invention relates to wireless relay technology in the field of wireless communication, in particular to a method and system for negotiating and determining an RN working mode. Background technique

[0002] The Long Term Evolution (LTE, Long Term Evolution) system of the third generation mobile communication is developed by the Third Generation Partnership Project (3GPP, Third Generation Partnership Projects) based on Orthogonal Frequency Division Multiple Access (OFDMA, Orthogonal Frequency Division Multiple Access) technology. New wireless communication system. Compared with the existing wireless communication technology, LTE has the advantages of large data transmission bandwidth, high spectrum efficiency, and good anti-interference to wireless signal multipath interference, and is the main technology of the next generation communication system. The LTE system consists of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Un...
