Inventor recognizes for D2D broadcast communication, can build the pattern of transmission resources set that UE uses based on walsh matrix.If about fix in D2D broadcast communication, (base station assigns) transfer resource that UE takies is 8 subframes, then can utilize 8 rank walsh matrix W as shown in Figure 1
8,1with its complementary matrix W
8,2determine the pattern of transmission resources of D2D broadcast communication.Wherein complementary matrix W
8,2for-1 is multiplied by walsh matrix W
8,1.
In FIG, walsh matrix W can be made
8,1with its complementary matrix W
8,2in their the first row of removing outside certain a line in element correspond respectively to UE for the operable transfer resource of D2D broadcast communication, i.e. 8 subframes.The corresponding subframe that the UE carrying out D2D broadcast communication can use the unit in this row usually to determine in 8 subframes receives grouping or sends grouping.Such as, element+1 in certain row vector of matrix can the indicating positions subframe corresponding with the element in this row vector for sending grouping, the element-1 in certain row vector of matrix can the grouping that sends for receiving other equipment of the indicating positions subframe corresponding with the element in this row vector.But, based on such mechanism, if each element indicates a subframe, transmission or the reception of 8 subframes can only be indicated at most, and the situation that operable transfer resource is the subframe beyond 8 cannot be tackled, the particularly situation of such as 12,20 subframes.Therefore be necessary that a kind of more flexible and effective scheme of design is suitable for transmission or the reception of more subframes.
Especially, because the rank M of walsh matrix is 2
kk=1,2,3 ... then when the UE number of subframes N carried out shared by D2D broadcast communication is not equal to the rank of walsh matrix, particularly when number of subframes N is not the integer multiple of M, such as N=12 or N=20, how effectively to distribute the transfer resource of such as subframe, be this area faced by further challenge.Embodiments of the present invention may be used for solving above-mentioned challenge.
Fig. 2 diagram is according to the flow chart of the communication means 200 of an embodiment of the invention.The method starts from step S200.
In step S210, N number of subframe is unevenly divided into M subframe group.Wherein N is not the integer multiple of M.Such as, the number N of carrying out the subframe of D2D communication in the base station assigns of radio honeycomb communication system to UE is 12, if utilize 8 rank walsh matrix W as shown in Figure 1
8,1with its complementary matrix W

8,1with its complementary matrix W
8,2in each row vector except their the first row in each element can correspond to a subframe group in 8 subframe groups.
In step S230, the row vector based on extended matrix determines the subframe for sending grouping sent in the subframe group of grouping.Such as, the value of the element in the row vector of extended matrix can represent numbering in subframe group of relative subframe for sending grouping and relative position.
In step S240, use the determined relative subframe for sending grouping to send grouping.Such as, in the sight of D2D broadcast communication, send grouping utilizing in the subframe specified by fundamental matrix and extended matrix, and in other subframes, receive the grouping that other UE send.
Method shown in Fig. 2 terminates in step S250.
It should be noted that, in description herein, the element+1 of walsh matrix has relative meaning with-1 with the transmission of subframe group and the corresponding relation that receives attribute, namely also can define subframe group corresponding to element-1 value in matrix is subframe group for sending grouping, and the subframe group of element+1 value correspondence in matrix is the subframe group for receiving grouping.
Also should be noted that, also the matrix outside walsh matrix can be used to build fundamental matrix, first value (such as " AA ") of the element in row vector wherein represents that subframe group corresponding to the position of this element is the subframe group for sending grouping, and second value (such as " BB ") of the element in the row vector of described fundamental matrix represents that subframe group corresponding to the position of this element is the subframe group for receiving grouping.
When realizing, fundamental matrix and extended matrix can be pre-selected and build and can be obtained by the executive agent of said method 200 (such as, D2D broadcasts UE).
Below by specific embodiment, the implementation method of communication means of the present invention and the construction method of fundamental matrix and extended matrix are described.

The number 12 of broadcasting the subframe of UE owing to distributing to D2D is not the integer multiple of 8, and 12 all subframes being allocated for a transmission VoIP grouping can only be unevenly divided into 8 subframe groups, and subframe group is made up of the subframe of different number.Fig. 3 illustrates a kind of possible division in this situation.In figure 3, a subframe is illustrated as 1ms, compatible mutually to communicate with the D2D in traditional cellular communications network or LTE communication.
As shown in Figure 3, for 4 subframe groups, each subframe group is only made up of (relative subframe numbers is 0) a subframe; For rear 4 subframe groups, each subframe group is made up of (relative subframe numbers is 0 and 1) two subframes.
Fundamental matrix can based on 8 rank walsh matrix W as shown in Figure 1
8,1with its complementary matrix W
8,2build.Similarly, because the first behavior+1 or-1 of these two matrixes, the transmission in can not effectively indicating D2D to communicate and reception subframe, so foreclose the first row.By 8 rank walsh matrix W
8,1matrix after removing the first row is designated as the first matrix H 1, by complementary matrix W
8,2matrix after removing the first row is designated as the second matrix H 2.Like this, based on the value of the element in the first matrix H 1 or the second matrix H 2, subscriber equipment can determine the subframe group sending and receive.Such as, being worth for the element of+1 is corresponding to the subframe group for sending, being worth for the element of-1 is correspondingly corresponding to the subframe group for receiving.Wherein D2D broadcasts UE and only in a subframe in the subframe group sent, sends grouping, and other subframes in this subframe group receive grouping.
Extended matrix is for determining the relative subframe for sending grouping in the subframe group for sending.The extended matrix of example one can build by carrying out as illustrated in figs. 4 a-4d.

Extended matrix E, E shown in Fig. 4 A-4D ', E " in, the smallest hamming distance in extended matrix between any two row is set to 2.
For example, D2D broadcasts UE and can select 8 rank Walsh complementary matrix W
8,2in the 6th row determine send VoIP grouping subframe group.As shown in the dotted line frame in Fig. 5, the row vector of selection is [-1+1-1+1+1-1+1-1].This means subframe group 2,4,5,7 for sending subframe group, subframe group 1,3, and 6,8 for receiving subframe group, and UE sends in transmission subframe group 2,4,5,7.
D2D broadcasts UE and the extended matrix E shown in Fig. 4 A then can be selected to select the relative subframe for dividing into groups in subframe group.As shown in the dotted line frame in Fig. 6, the row vector of selection is [0001].This means that UE is in the subframe group 2,4,5 for sending, the respective relative subframe 0,0,0 in 7, carries out transmission VoIP and divides into groups on 1.This just corresponds to the pattern of transmission resources that transmission VoIP shown in figure 3 divides into groups.

8,1with complementary matrix W
8,2and build extended matrix E, E ' and E " characteristic, the constructed possible pattern of transmission resources for 12 subframes has following characteristic:
1.D2D broadcast UE sends such as VoIP and divides into groups 4 times.The experiment of link level simulation shows, a VoIP grouping is carried out 4 transmission and just can be met the requirement that receiver reference sensitivity Signal to Interference plus Noise Ratio (SINR:SignaltoInterferenceandNoiseRatio) is-107dBm.Therefore, the fundamental matrix built according to illustrative examples one of the present invention and extended matrix can meet such requirement.
2., for any two the broadcast UE using different transmission mode, a broadcasting user equipment UE 1 at least can receive sending for 2 times of grouping from another broadcasting user equipment UE 2, and vice versa.Which solves half-duplex restricted problem:
(1) if UE1 and UE2 adopts walsh matrix W
8,1with its complementary matrix W
8,2in different row build pattern of transmission resources, then UE1 at least can receive 2 transmission from UE2, and vice versa, and this is determined by the characteristic of walsh matrix; And
(2) if UE1 and UE2 adopts walsh matrix W
8,1with its complementary matrix W
8,2in identical row and extended matrix E, E ' and E " in different row build pattern of transmission resources; then UE1 at least can receive 2 transmission from UE2; and vice versa, this be by any two row in extended matrix between smallest hamming distance be 2 characteristic determine.

8,1with its complementary matrix W
8,2in pattern of transmission resources corresponding to the 2nd, 3,4,6,7 and 8 row have 12.

In above example one and example two, the repeatedly transmission of VoIP grouping carries out at random in time domain, which reduces leakage problem in the band of receiving terminal.And the pattern of transmission resources of technical scheme of the present invention can realize randomization effect in time domain.
Once at walsh matrix W
8,1with its complementary matrix W
8,2, and extended matrix E, E ' and E " in have selected concrete row vector, then pattern of transmission resources is just determined.The determination of pattern of transmission resources makes to receive UE and can conveniently receive grouping/merge.If the pattern of transmission resources determined sends before sending packets, or send together with grouping in pattern of transmission resources information included in the head of encapsulating packets, then embodiments of the present invention can reduce signaling consumption effectively.Such as, add up to 33 for what build based on 8 rank walsh matrixs for the available transmission resources transmission mode in the pattern of transmission resources set of 12 subframes, can represent to multiplex 6 bits.Add up to 149 for what build based on 8 rank walsh matrixs for the available transmission resources transmission mode in the pattern of transmission resources set of 20 subframes, can represent to multiplex 8 bits.
