Description

Terminal-to-terminal service (Device to Device, D2D) communication technology is a kind of technology of end-to-end direct communication, it is with traditional maximum difference of cellular telecommunication art, communication between terminal and terminal no longer needs the transfer of base station directly to can be carried out communicating, base station can carry out configuration, scheduling, coordination of resource etc., assist directly being communicated between terminal.
Currently, long term evolution (Long Term Evolution is used in the D2D communication technology, LTE) technology, LTE technology uses orthogonal frequency-time multiple access (orthogonal frequency divided multiple access, OFDMA) technology, the information of user is carried on mutually orthogonal different carrier waves in such a way that the orthogonality between frequency is as differentiation user, can effectively antagonize frequency selective fading by OFDMA technology.In addition, since the frequency that intra-cell users use is mutually orthogonal, all interference are all from other cells, Signal to Interference plus Noise Ratio (the Signal to Interference plus Noise Ratio of Cell Center User can also be greatly improved in this way, SINR), so as to providing higher data rate and better service quality.And for the user of cell edge, due to the user that neighboring community occupies same carrier resource it is interfered it is bigger, in addition itself apart from base station farther out, its SINR is relatively just smaller, although leading to the situation that the handling capacity of entire cell is higher but Cell Edge User service quality is poor, handling capacity is lower, therefore, the intra-cell interference very little in D2D system, and the main interference of system performance is influenced from inter-cell interference.
In order to solve the problems, such as D2D system in cell edge serious interference, in the prior art, when carrying out scheduling of resource to terminal, using interference coordination/avoid technology, for example, partial frequency multiplexing
(Fractional Frequency Reuse, FFR) Inter-Cell Interference Coordination algorithm, part-time are multiplexed (Fractional Time Reuse, FTR) Inter-Cell Interference Coordination algorithm.The basic thought of interference coordination/avoid technology is the interference between the terminal of cell edge to be reduced, to promote the performance of cell entirety for the orthogonal time resource of the terminal distribution of cell edge or orthogonal frequency resource.
However, the resource initial position of each cell is to be pre-configured, and when the load imbalance of minizone, the utilization rate that will lead to resource using resource regulating method in the prior art is not high since FFR or FTR are coordinating semi-static interference algorithms.

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is described.
Fig. 1 is the application scenarios schematic diagram that resource regulating method provided in an embodiment of the present invention is based on, referring to Fig.1, cell 1 (Cell1) and cell 2 (Cell2) neighboring community each other, cell 1 is covered by base station 1, cell 2 is covered by base station 2, terminal U1 and terminal U6 belong to cell 1, terminal U2, terminal U3, terminal U4 and terminal U5 belong to cell 2, terminal U1, terminal U2, terminal U3, terminal U4, terminal U5 and terminal U6 are all made of D2D communication mode, when base station 1 in cell 1 terminal U1 and terminal U6 carry out scheduling of resource when, the number of users to be dispatched of cell 2 can be first obtained from base station 2, the resource that cell 2 uses is estimated according to the number of users to be dispatched, that is, determine cell 2 in next tune according to the number of users to be dispatched Spend resource to be used in the period, by cell 1 terminal U1 and terminal U6 be dispatched to the resource not used by cell 2.
In the embodiment of the present invention, user is equal with the meaning of terminal, and number of users to be dispatched can be understood as to dispatch terminal number.
It should be noted that above-mentioned application scenarios are by way of example only rather than limitation of the invention, in the embodiment of the present invention, current area can have a neighboring community, can also there is multiple neighboring communities, it is above-mentioned it is multiple be at least two.If there are multiple neighboring communities in current area, base station can estimate the resource that one of neighboring community uses, by the terminal scheduling in current area to the resource not used by a neighboring community when carrying out scheduling of resource for the terminal of current area；Alternatively, the resource that wherein each neighboring community uses can be estimated, by the terminal scheduling in current area to the resource not used by any one neighboring community.
Wherein, the resource mentioned in the embodiment of the present invention is transfer resource, is specifically as follows time resource perhaps frequency resource or time resource and frequency resource.
Fig. 2 is scheduling of resource schematic diagram when not using Inter-Cell Interference Coordination technology, referring to Fig. 2, if two minizones do not interfere with coordination, resource between terminal may be mutually conflicting, the resource of terminal U1 is distributed in the base station 1 that coverage cell 1 is shown in left figure, and the base of coverage cell 2 is shown in right figure
It stands 2 resources for distributing to terminal U2, terminal U3, terminal U4 and terminal U5.When terminal U1 carries out the transmission of D2D data in cell 1 in the form of broadcast, since terminal U2, terminal U3, terminal U4 and the terminal U5 in cell 2 may carry out the transmission of data on the same resource, therefore interference can be generated to the data that terminal U1 is sent, there are stronger interference when terminal U6 being caused to receive the data of terminal U1, so that the receptivity of cell-edge terminals declines, resource regulating method through the embodiment of the present invention can effectively improve the receptivity of cell-edge terminals.
Fig. 3 is the resource regulating method flow chart that the embodiment of the present invention one provides, and this method is used for using multiple terminals of D2D communication mode to carry out scheduling of resource in current area, and the executing subject of this method is the base station of covering current area, this method comprises:
Step 301, base station obtains the number of users to be dispatched of the neighboring community of current area in next dispatching cycle.
Wherein, number of users to be dispatched in the interaction of the interface (The interface between eNodeBs, X2) between evolved base station next dispatching cycle can be passed through between neighboring community.
, can be when neighboring community be met certain condition in the embodiment of the present invention, then the number of users to be dispatched of the neighboring community of current area in next dispatching cycle is obtained, otherwise without obtaining.Specifically, it is in advance each cell setting dispatching priority, such as, it is each cell setting dispatching priority according to the classification of cell, either according to mark (Cell ID) configuration scheduling priority of each cell, when carrying out scheduling of resource to current area, judge whether the dispatching priority of the neighboring community of current area is higher than the dispatching priority of current area, when the dispatching priority for the neighboring community that judging result is current area is higher than the dispatching priority of current area, obtain the number of users to be dispatched of the neighboring community of current area in next dispatching cycle, so as to the subsequent resource that can be estimated the neighboring community and use, the resource used according to the neighboring community carries out scheduling of resource to the terminal of current area.
Such as, using the scheduling of certain a kind of cell (such as Cell A) as a benchmark, the base station of other cells is when dispatching the user of this cell, it may estimate that the resource service condition of such cell, specifically, neighboring community, the dispatching priority for presetting Cell A are higher than the dispatching priority of Cell B each other by Cell A, Cell B and Cell C, and the dispatching priority of Cell B is higher than the dispatching priority of Cell C.Referring to Fig. 4 institute
A kind of scheduling of resource schematic diagram shown, when the base station for covering Cell A carries out scheduling of resource to the terminal of Cell A, due to the dispatching priority highest of Cell A, there is no need to obtain the number of users to be dispatched of neighboring community, the user of the cell is scheduled according to normal sequence；When the base station for covering Cell B carries out scheduling of resource to the terminal of Cell B, the resource service condition of Cell A can be estimated, by terminal scheduling to the resource not used by Cell A according to the number of users to be dispatched of the Cell A of X2 interaction；When the base station for covering Cell C carries out scheduling of resource to the terminal of Cell C, it can be according to the number of users to be dispatched of the Cell A of X2 interaction, estimate the resource service condition of Cell A, and, according to the number of users to be dispatched of the Cell B of X2 interaction, the resource service condition of Cell B is estimated, thus by terminal scheduling to the resource not used by Cell A and Cell B.
Step 302, according to the number of users to be dispatched of neighboring community, the resource that neighboring community uses is estimated.In the embodiment of the present invention, the resource that neighboring community uses can be estimated directly according to the number of users to be dispatched of neighboring community；Or, judge whether the number of users to be dispatched of neighboring community is less than the number of users to be dispatched of current area, when judging result is neighboring community wait dispatch number of users less than current area when dispatching number of users, further according to the number of users to be dispatched of neighboring community, the resource that neighboring community uses is estimated.
Such as, will the least cell of number of users be dispatched as benchmark cell, the base station of other cells may estimate that the resource service condition of benchmark cell, thus by the terminal scheduling of this cell to the resource not used by benchmark cell when the terminal to this cell carries out scheduling of resource.Specifically, the neighboring community each other Cell A, Cell B and Cell C, the number of users to be dispatched of Cell B is less than the number of users to be dispatched of Cell C, the number of users to be dispatched of Cell C is less than the number of users to be dispatched of Cell A, since the number of users to be dispatched of Cell B is minimum, therefore using Cell B as benchmark cell, using the scheduling of Cell B as a benchmark.Another scheduling of resource schematic diagram referring to Figure 5, when the base station for covering Cell B carries out scheduling of resource to the terminal of Cell B, since the number of users to be dispatched of Cell B is minimum, therefore it is scheduled when dispatching the terminal of Cell B according to normal dispatching sequence, the dispatch situation without considering other cells；When the base station for covering Cell C carries out scheduling of resource to the terminal of Cell C, the resource service condition of Cell B can be estimated, by terminal scheduling to the resource not used by Cell B according to the number of users to be dispatched of the Cell B of X2 interaction；It, can root when the base station for covering Cell A carries out scheduling of resource to the terminal of Cell A
According to the number of users to be dispatched of the Cell B of X2 interaction, the resource service condition of Cell B is estimated, and, according to the number of users to be dispatched of the Cell C of X2 interaction, the resource service condition of Cell C is estimated, thus by terminal scheduling to the resource not used by Cell B and Cell C.
Normally, when base station carries out scheduling of resource to terminal in cell, it is all made of FFR or FTR coordinating semi-static interference algorithm.Fig. 6 is the scheduling of resource schematic diagram using FFR coordinating semi-static interference algorithm, in FFR scheme, entire frequency domain resource is divided into main resource part (Major part) and secondary resource part (Minor part) two parts, Major part between neighboring community is orthogonal, user in each cell is according to Reference Signal Received Power (Reference Signal Receiving Power, RSRP) be preferentially assigned to Major part from low to high, it is then dispensed for Minor part, edge customer is preferentially assigned to Major part in this way, the user of center of housing estate is assigned to Minor part, so that between neighboring community The resource of edge customer be it is mutually orthogonal, can achieve reduce inter-cell interference purpose.Cell A distributes resource since lowest band, resource allocation is carried out from low to high according to the size of RSRP, Cell B uses similar allocation plan with Cell C, only resource initial position is respectively 1/3 frequency band, 2/3 frequency band, when resource allocation is to highest frequency band, then since lowest band from low to high distribute.Fig. 7 is the scheduling of resource schematic diagram using FTR coordinating semi-static interference algorithm, and FTR scheme is similar with FFR, and difference is resource allocation since minimum time resource.
Since the resource initial position of each cell is pre-configuration, and preset resource regulating method is used, therefore in acquisition neighboring community after dispatching number of users, so that it may according to the number of users to be dispatched of neighboring community, estimate the resource that neighboring community uses.
Step 303, come when next dispatching cycle temporarily, according to the resource that the neighboring community estimated uses, by each of multiple terminals terminal scheduling to the resource not used by neighboring community.
Wherein, the resource of cell includes main resource part and secondary resource part, the main resource part of current area and the main resource partial orthogonality of neighboring community, the secondary resource part of current area and the secondary resource part fractional reuse of neighboring community.
In the embodiment of the present invention, the RSRP of each of multiple terminals terminal is first obtained, then the sequence according to RSRP from low to high, by the main resource of the part terminal scheduling in multiple terminals to current area
Part, by the secondary resource part of remaining terminal scheduling in multiple terminals to current area, wherein when by the secondary resource part of remaining terminal scheduling to current area, according to the resource that the neighboring community estimated uses, by remaining terminal scheduling to the resource not used by neighboring community.
Wherein, step 302 can be equal to following statement: according to the number of users to be dispatched of neighboring community, in the transfer resource of the neighboring community, determine dispatch the neighboring community wait dispatch the first transfer resource required for number of users.Correspondingly, step 303 can be equal to following statement: temporarily, according to the first determining transfer resource, the resource of the first transfer resource will to be not belonging in the transfer resource of each of multiple terminals terminal scheduling to current area when next dispatching cycle.
