Embodiment 1

[0099] Embodiment 1. This embodiment mainly describes the network topology diagram of the layered network, such as image 3 As shown, the network elements of the access network included in the layered network are the macro base station (Macro), the relay (Relay), the user (MUE) belonging to the macro base station, and the user (RUE) belonging to the relay. image 3 The RUE in the dashed line is the marginal RUE.

Embodiment 2

[0100] Embodiment 2, resource allocation scheme on the Uu subframe.

[0101] In this embodiment, the resource allocation process is briefly described by taking Type0 resource allocation (refer to the 3GPP TS36.213 protocol for details) as an example.

[0102] In the Uu subframe, some resources in the system bandwidth occupied by different Macro base stations may be the same, partly or completely different. Such as Figure 4 Part of the resources in the system bandwidth occupied by the macro base station 1 and the macro base station 2 are different. The Relay can occupy all the resources of the system bandwidth for resource allocation. Preferably, for the edge RUE in the Relay, the Relay tries to allocate resources different from those occupied by the Macro base station. Such as Figure 4 Among them, the edge RUE of relay 1 belonging to macro base station 1 occupies different resources from macro base station 1; the edge RUE of relay 2 belonging to macro base station 2 occu...

Embodiment 3

[0103] Embodiment 3, the resource allocation scheme on the Un subframe.

[0104] Take Type0 resource allocation as an example to briefly describe the resource allocation process, such as Figure 5 Shown:

[0105] The Macro station schedules special users such as the MUE and the Relay, and the MUE and the Relay station share all available resources in the system bandwidth, and ensure the performance of the Relay station by adjusting the priority.

[0106] The processing flow of the above method can be realized by a software program, and the software program can be stored in a storage medium, and when the stored software program is invoked, the steps of the above method are executed.

[0107] Based on the same inventive concept, an embodiment of the present invention also provides a macro base station, the macro base station is applied in hierarchical networking, see Figure 6 As shown, the macro base station includes:

[0108] A judging module 61, configured to judge the typ...

Abstract

The invention discloses a resource distribution method and device in layered networking. The method includes the steps that when downlink resources are distributed, the type of the current subframe is judged by a macro base station; if the subframe is a Un subframe, the macro base station determines the priority which belongs to a relay and MUE of the macro base station, the resources are distributed to the relay and the MUE of the macro base station according to the determined priority, and a first CQI correction result is obtained by correcting CQIs reported by the MUE and the relay on the Un subframe respectively through the macro base station; if the subframe is a Uu subframe, the priority of the MUE which belongs to the macro base station is determined through the macro base station according to a second CQI correction result, the resources are distributed for all MUE according to the determined priority, and a second CQI correction result is obtained by correcting CQIs reported by the MUE on the Uu subframe respectively through the macro base station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method and equipment in layered networking. Background technique [0002] In the Long Term Evolution (LTE) system, wired connections are used between base stations and between base stations and the core network, which brings greater deployment difficulty and higher network deployment to operators. cost. In order to solve the above problems, the third generation partnership project (The3 rd Generation Partnership, 3GPP) introduced the wireless relay technology (Relay) in the long-term evolution enhancement (LTE-Advanced, LTE-A), and the relay connects to its home macro base station through wireless, forming a Relay / macro (Macro) base station split Layer networking to improve throughput performance, especially edge throughput performance. With the introduction of trunking, there are three air links: [0003] 1. The interface between the rel...
