example 1

[0055] The following uses a specific OAM system as an example to illustrate, assuming that the initial uplink and downlink configuration mode of the DeNB cell in the OAM system is 1, the initial configuration mode of the Un subframe is 0, the subframe reconfiguration period T is 1s, and the DeNB downlink is allocated to the The maximum value T of the following node buffer max-eNodeB 3000000bytes, the maximum value of RN downlink buffer T max-relay is 250990bytes, and the buffer critical ratio α is 75%.

[0056] 1. The DeNB obtains the subframe configuration mode through the Operation Administration and Maintenance (OAM) system. The initial uplink and downlink configuration mode of the DeNB cell is 1, the initial configuration mode of the Un subframe is 0, and the subframe reconfiguration period T is 1s.

[0057] 2. The RN starts up, accesses the network through the normal UE attachment process, and obtains the initial configuration mode of the Un subframe as 0.

Abstract

The invention relates to a method and system for reconfiguring a relay subframe, and belongs to the technical field of wireless communication. The present invention predicts the traffic volume of the eNodeB and the Relay in the next subframe adjustment period according to the change of the eNodeB and the Relay traffic in the previous N subframe adjustment period, and judges whether the traffic of the DeNB and the Relay in the next subframe adjustment period is predicted. It is necessary to add Un subframes or reduce Un subframes, and reconfigure the RN subframes according to the results. When subframes need to be added, the number of subframes selected in the Un subframe configuration method corresponding to the DeNB cell uplink and downlink configuration method is increased. When the subframe configuration method needs to be reduced, the subframe configuration method with the reduced number of subframes is selected from the Un subframe configuration method corresponding to the uplink and downlink configuration method of the DeNB cell, so as to realize the configuration of subframes according to the traffic volume The method is adjusted to avoid the problem of data congestion caused by unreasonable subframe configuration. The invention is simple and easy to implement, easy to implement in engineering, and improves the performance of the relay node.

Description

technical field [0001] The invention relates to a method and system for reconfiguring a relay subframe, and belongs to the technical field of wireless communication. Background technique [0002] As an emerging technology, relay technology has attracted more and more attention, and is regarded as the key technology of B3G / 4G. In wireless communication systems, in order to increase coverage or provide hotspot services, the use of relay technology has become a important technical means. Such as figure 1 As shown, a relay node (RN, Relay Node) is wirelessly connected to its home eNodeB cell. After the RN is introduced, the backhaul link between the RN and its home eNodeB (Donor, DeNB) becomes the Un interface. In a Type1 trunk, the Un interface and the Uu interface use the same carrier resources. To avoid interference between the Un interface and the Uu interface, the two links work in a time-division manner. The 3GPP standard provides 19 Un subframe allocation methods confi...
