Method and device for scheduling resources for mobile terminals in wireless relay network

Abstract

A resource scheduling method and device for a mobile terminal belonging to a relay station in the wireless multi-hop relay network. The mobile terminal detects the signal quality of the downlink signal from the network equipment. If the signal quality meets the predetermined condition, the mobile terminal sends a first notification message to the network equipment. According to the total quantity of the free wireless resource controlled by the network equipment, and the total quantity of the free wireless resource controlled by the relay station, the network equipment allocates the resource for the mobile terminal. If the signal quality doesn't meet the predetermined condition, the mobile terminal sends a second notification message to the network equipment. According to the wireless resource controlled by the relay station, the network equipment notifies the relay station to allocate the resource for the mobile terminal with the use of wireless resource controlled by the relay station.

Description

technical field [0001] The present invention relates to a wireless relay network, in particular to a method and a device for scheduling resources for a mobile terminal under the jurisdiction of a relay station in the wireless relay network. Background technique [0002] In IEEE802.16j, two types of relays are defined: transparent relays and opaque relays. [0003] Transparent relay can only be used to improve the throughput of the mobile terminal at the edge of the cell and increase the capacity of the system, it does not expand the coverage of the cell. Therefore, in the wireless relay network, the mobile terminals governed by the transparent relay must be within the coverage of the base station. The mobile terminal under the control of the transparent relay obtains control information directly from the base station, wherein the control information includes information such as a preamble symbol and a mapping table. [0004] Usually, a centralized resource scheduling mecha...

Problems solved by technology

However, in the existing opaque relay network scheduling mechanism, this downlink channel cannot be used to transmit downlink control information, and at the same time, the base station resources cannot be used to transmit on the channel between the relay station 20' and the mobile terminal 10' data information, which leads to when the load between the relay station 20' and the base station 30' is unbalanced, for example, the relay station 20' is heavily loaded, while the base station 30' is lightly loaded, and the relay station 20' cannot utilize the resources of the base station 30' To bear the load, so that the wireless resources of the entire wireless system cannot be used reasonably
