Embodiment Construction

[0027] The basic idea of ​​cooperative relay technology is to allow multiple single-antenna users (ie nodes) to share antennas to form a virtual multi-antenna cooperative transmission, so that single-antenna users can also obtain space diversity, so as to expand network coverage, The purpose of improving transmission rate and extending battery life. This technology can be used in the traditional cellular network relay station to further improve the system performance of the cellular network.

[0028] At present, the performance of different cooperative relay protocols has its own advantages in actual use, and the cellular network using a single cooperative relay protocol cannot obtain the maximum performance gain. For this reason, the embodiment of the present invention provides a kind of processing method of cooperative relay protocol, such as figure 1 shown, including the following steps:

[0029] Step s101 , for a specific performance parameter, respectively acquire the p...

Abstract

The invention discloses a method and equipment for resource allocation. The method comprises the following steps: for specific performance parameters, respectively obtaining performance indexes which can be realized under different cooperative relay protocols and resource allocation conditions used for realizing the performance indexes; comparing the performance indexes which can be realized by different cooperative relay protocols and selecting the cooperative relay protocol for realizing the optimal performance index; and carrying out resource allocation according to the resource allocatingcondition used for realizing the optimal performance index. By using the embodiment of the invention, for the specific performance parameters, the performance indexes which can be realized by adoptingdifferent cooperative relay protocols are respectively obtained, and then the cooperative relay protocol for realizing the optimal performance index and the resource allocation condition for realizing the optimal performance index are selected. The invention ensures that a cellular network of a traditional relay station can obtain greatest performance gain of multiple cooperative relay technologies without upgrading hardware.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method and equipment. Background technique [0002] With the increasing demand for wireless broadband services, future wireless communication systems must meet various high-speed applications. Currently 4G (4 th Generation, the fourth generation of digital communication) The carrier frequency (>5GHz) used by the system will be much higher than the carrier frequency (<2.2GHz) of the current system, because a higher rate means less transmission energy per bit, so it will be This leads to more serious signal fading, making it impossible for the 4G system to obtain the same coverage performance as the current system. An effective method to solve the coverage problem in the prior art is to set a RS (Relay station, relay station), and use the relay station to assist communication. Using relays as an inexpensive technology effectively enhan...
