Specific implementation mode
An embodiment of the present invention provides a kind of resource collision information transferring method and devices, with to avoid no generation resource
The case where node release resource of collision, to reduce the frequency of node gravity treatment resource, improve the performance of system.
Resource described in the embodiment of the present invention is illustrated by taking time slot as an example, single for the minimum of TDM, i.e. resource
Position is with regard to an entire time interval resource, for FDM, i.e., multiple one time interval resource of node frequency division multiplexing, in this case, resource
Least unit just not instead of time slot, time frequency block.
The embodiment of the present invention carries out following optimization process mainly for the prior art.The detection that base station collaboration mode is collided:
Node persistently does bottom measurement, when detecting strong jamming time slot, report collision information (strong jamming occur when
Gap, can be by reporting the currently time slot difference realization with place time slot), and incidentally previous frame or the preceding multiframe node in this message
(come if previous frame node does not decode, can only send capable and experienced in the node ID that time slot where the strong jamming is correctly decoded
Instruction is disturbed, strong jamming instruction can not also be sent to base station).Management station reports information to determine the section to collide according to strong jamming
Point ID sends downstream message to the node that may be collided and (when specific implementation, directly forwards corresponding information, such as
There is extra information in fruit base station, can also be determined according to corresponding information and indicate slightly remote node to discharge).Receive this message
Node, restart to monitor, select time interval resource.It should be noted that only being sent again to the node ID being reported here
Gap information is selected, is not to send strong jamming instruction to occupying all nodes of the time slot.
I.e. in this case, the collision of time slot is in accordance with bottom measurement detected, and between node not
It needs to interact any Overhead (characteristic of program itself).
Compared with self-organization network mode, it may occur however that the node of collision all discharges time interval resource, here only part
Node discharges time interval resource.In general, the continuity for increasing business improves the reliability of system.
It should be noted that:In the embodiment of the present invention, node does bottom measurement to detect strong jamming, may be used with lower section
Formula:It can be judged by SINR and the ratio of reception general power.For example it is more than certain thresholding to receive general power, but SINR is small
In certain thresholding, it is possible to determine that strong jamming has occurred;It can also be judged by the value of jamming power, for example according to SINR and connect
General power is received, signal power is determined, further determines that jamming power, if jamming power is higher than some thresholding, it is possible to determine that
Strong jamming has occurred.The specific value of above-mentioned each thresholding can be decided according to the actual requirements.

This information so that the node of resource collision, which occurs, can identify this information, and then the node of resource collision only really occurs
The case where needing to discharge resource and carry out resource gravity treatment, avoiding the node release resource not collided, to reduce
The frequency of node gravity treatment resource, improves the performance of whole system.
Preferably, detecting whether any resource collides in the following way:
For any resource, by signal and interference and noise ratio SINR, and general power is received, judge whether the resource is sent out
Resource collision is given birth to;Alternatively, judging whether the resource has occurred resource collision by jamming power.
Preferably, determining the identification information of the node to collide in the collision resource, specifically include:
Resource identical with the resource number to collide in particular frame before determining present frame, and determine at this

The illustration of a specific embodiment is given below:Base station additional time slots collision molange.
For example, there are three node, respectively node A, node B, node C, these three node spaces are multiplexed identical resource,
Such as time slot X (base station is not aware that these information).
Node D detects strong jamming in time slot X, while in next frame, (100ms or 1s depend on system maintenance to node D
Period) to base station report this information, and the section that the time slot X instructions comprising collision and previous frame listen in the information
The mark of point A.
