Problems solved by technology

However, there is currently no method for negotiating between the RN and the DeNB to determine the working mode of the RN, so as to ensure that when the RN accesses the DeNB, the working mode of the RN is consistent with the working mode of the RN recorded on the DeNB

Embodiment 1

[0070] In this embodiment, the RN only supports the time-division half-duplex mode, and the working mode of the RN has been pre-configured to be time-division half-duplex mode manually, such as image 3 As shown, the process of negotiating and determining the working mode of the RN specifically includes the following process:

[0071] Step 301, the RN starts to access the DeNB, sends an RRC Connection Request (RRCConnection Request) signaling to the DeNB, and carries its pre-configured time-division half-duplex mode in the RRC Connection Request signaling;

[0072] Step 302, the DeNB receives the RRC Connection Request sent by the RN, and returns the RRC Connection Setup (RRC Connection Setup) signaling to the RN;

[0073] Step 303, the RN receives the RRC Connection Setup sent by the DeNB, and returns the RRCRRC connection setup completion (Connection Setup Complete) signaling to the DeNB;

[0074] Step 304, the DeNB receives the RRC Connection Setup Complete sent by the RN,...

Embodiment 2

[0076] In this embodiment, RN only supports time-division half-duplex mode, and its working mode has been pre-configured in RN to be time-division half-duplex mode manually, such as Figure 4 As shown, the process of negotiating and determining the working mode of the RN specifically includes the following process:

[0077] Step 401, the RN starts to access the DeNB, sends an RRC Connection Request to the DeNB, and carries its pre-configured time-division half-duplex mode in the RRC Connection Request signaling;

[0078] Step 402, the DeNB receives the RRC Connection Request sent by the RN, determines that the working mode of the RN is the pre-configured time-division half-duplex mode, returns the RRC ConnectionSetup to the RN, and carries the recorded RN in the RRC Connection Setup signaling Time-division half-duplex mode, explicitly inform the RN that it has accepted the RN pre-configured working mode;

[0079] Step 403, the RN receives the RRC Connection Setup sent by the ...

Embodiment 3

[0082] In this embodiment, the RN supports the time-division half-duplex mode and the full-duplex mode at the same time, and its working mode has been pre-configured in the RN to be full-duplex in a manual manner, such as Figure 5 As shown, the process of negotiating and determining the working mode of the RN specifically includes the following process:

[0083]Step 501, the RN starts to access the DeNB, sends RRC Connection Request signaling to the DeNB, and carries its pre-configured full-duplex mode in the RRC Connection Request signaling, and also carries the pre-configured frequency parameters for the Uu interface;

[0084] Step 502, the DeNB receives the RRC Connection Request sent by the RN, judges that it does not support the pre-configured frequency parameters for the Uu interface or does not allow the pre-configured frequency parameters for the Uu interface, and then sends a time-division half-duplex message to the RN. The RRC Connection Setup signaling in the worki...

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...
