A method and system for association in a relay network are disclosed; a neighbor Base Station (BS) receives a ranging request from an associated neighbor station and the ranging request is received by the associated neighbor station from an MS; the neighbor BS sends a ranging response to the MS in response to the ranging request; the associated neighbor station is an RS. Association Level 1 is implemented. Another method and system for association in a relay system are disclosed; a neighbor BS receives a ranging report from an associated neighbor station after the associated neighbor station receives a CDMA code from an MS; the neighbor BS sends the ranging report to the MS or to a serving BS by which the ranging report is sent to the MS; the associated neighbor station is an RS. Association Level 2 is implemented.

Method and system for association in relay network

A method for supporting MS ranging is provided in an embodiment of the present invention. The method includes: determining the public frame that is to be used for allocating the dedicated initial ranging transmission opportunity information; and notifying the MS of information about the determined public frame to potential target RSs. A BS and an RS are provided in embodiments of the present invention. This invention helps determine a public frame that is to be used for allocating the dedicated initial ranging transmission opportunity information for an MS in an MR radio telecommunication system, when the potential target BSs of the MS include RSs.

Method, base station and relay station for supporting mobile station ranging

The present invention provides a bandwidth method and a relay station (RS). After receiving the bandwidth request message sent by subordinate network entity, RS judges whether it has available bandwidth; if it has available bandwidth, sending a bandwidth request message to superordinate network entity based on the available bandwidth; otherwise, requesting bandwidth from superordinate network entity using CDMA ranging codes.

Bandwidth request method and relay station

A method for implementing a random access of a new access node and a system thereof are provided, which belong to a wireless communication field, and enable the new access node within the coverage of relay stations to implement the random access. In the application, when the new access node is located within the coverage of the relay stations, each of the relay stations notifies an access request sent from the new access node to a synchronization station via a report message, and the synchronization station compares the access request forwarded by each of the relay stations and the access request received by itself from the same new access node, selects a station with the best signal quality of the received access request, and implements the access of the new access node in accordance with the types of selected station and the synchronization station itself.
