[0064] Figure 4 Trigger implementation diagram for BS overload indicator (OI) report, such as Figure 4 As shown, its specific implementation steps are as follows:

[0065] Step 401: the BS determines an area division threshold;

[0066] Step 402: The BS stratifies the network according to the area division threshold;

[0067] Step 403: The BS determines the triggering thresholds of the overload indicator reports of different layers in the network;

[0068] Step 404: The BS determines the triggering threshold of the network overload indicator report;

[0069] Step 405: If the overload indicators in all network layers exceed the trigger threshold, go to step 406, otherwise go to step 408;

[0070] Step 406: BS sets the overload indicator group indication field;

[0071] Step 407, the BS sets the user terminal distinguishing field;

[0072] Step 408, the BS overload indicator is triggered and the field adjustment is completed;

Abstract

The invention discloses a report method for indicating the overloading of relay network, which includes: a base station or a relay station divides network into a plurality of layers according to one or a plurality of predetermined divided thresholds; the overloading report trigger thresholds are arranged at every layer by the base station; the base station or the relay station makes use of respective overloading indicator to make sure whether a plurality of layers are provided with the user terminals of the overloading report trigger thresholds with the strongest interference signals larger than the corresponding layers. And if yes, the base station or the relay station triggers the overloading indicator to report. With the method of the invention used, the network can be further refined to ensure the overloading indicator to report only the layers which exceed the trigger thresholds. Therefore, the system overhead which is brought by the overloading indicator report is reduced and the efficiency of the overloading indicator is improved.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a relay network overload indication reporting method. Background technique [0002] In the next-generation broadband wireless communication network, especially in the relay network with a relay station (RelayStation, RS), since the RS itself has the characteristics of both a user terminal (UserTerminal, UT) and a base station (Base Station, BS), Therefore, effectively reducing the inter-cell interference in the relay network according to the characteristics of the RS itself is a key factor to effectively improve the inter-cell user terminal (UT) throughput and the average UT throughput, and how to effectively use the relay station is also an important issue at present. serious challenges facing the research institute. [0003] At present, in IEEE 802.16j, IMT-Advanced, and WINNER, solutions such as interference randomization, interference coordination, and interfer...
