Abstract

The invention discloses a resource reusing method comprising the step that a base station or a relay station reuses resources in a relay zone or an access zone to transmit data to a plurality of low-level relay stations and / or a plurality of user terminals. By the characteristic that a space is reasonably divided and used, the method solves the problem of time-frequency resource utilization ratio reduction after a relay is introduced into a system, meanwhile, the coverage area of the relay station is ensured, and resources can be simply reused.

Description

technical field

[0001] The present invention relates to a method for reusing resources, in particular to when there is an RS (Relay Station relay station) in an OFDM (Orthogonal Frequency Division Multiplexing) system, Relay zone (relay zone) and Access zone (access zone) ) time-frequency resource reuse method. Background technique

[0002] The research goal of B3G / 4G is to gather access systems such as cellular, fixed wireless access, nomadic, and wireless area networks, combined with an all-IP network, to provide users with wireless transmission with a peak rate of 100Mbps and 1Gbps respectively in high-speed and low-speed mobile environments capabilities, and realize the seamless connection of cellular systems, regional wireless networks, broadcasting, and TV satellite communications, enabling human beings to realize "anyone can communicate with anyone else in any way at any time and anywhere". The Relay (relay) technology can be applied as an effective measure, and the ...

Examples

Embodiment Construction

[0020] In order to solve the disadvantages of the traditional technical solutions, the present invention further illustrates a resource reuse method in the present invention through the following specific examples. The specific implementation is described in detail below, but not as a limitation of the present invention.

[0021] Using the resource reuse method of the present invention, for resource reuse in the Relay zone, while the BS or RS sends data to a certain subordinate RS within its jurisdiction through the resources on the Relay zone, it also needs to send data to other RS ​​within the jurisdiction of the BS or RS. RS sends data, then the BS or RS reuses resources on the Relayzone to send data to these RSs;

[0022] For resource reuse in the Access zone, when the BS or RS sends data to a certain UT within its jurisdiction through the resources on the Access zone, it also needs to send data to other UTs within the jurisdiction of the BS or RS, then the BS or RS Reusin...
