Find number of sub-frames M in D2D resource area, in instruction D2D resource area, can be used for the number of sub-frames of D2D Signal transmissions.Can be support limited value, network side selects one of them to configure, and indicates manipulative indexing to subscriber equipment.Such as: to D2D communication, maximum support 8: { 1,2,4,8,16,32,64,128}, supposes to be configured to 16 (160ms), then indicate call number 4 to UE.Subscriber equipment, according to the index of instruction, determines D2D number of sub-frames in the resource area that D2D communicates.Here just give an example, the concrete D2D number of sub-frames supported can also more probable values, as 3,5,6,7,9,10,20,100 ... }.

The radio frames position that in D2D resource area, D2D subframe is corresponding, the position of instruction D2D subframe place radio frames.The position of radio frames can be indicated with the index of the sequencing of D2D subframe place radio frames in the corresponding cycle, such as, in assumption period, find subframe containing 3, respectively in 3 radio frames, then press frame number from small to large, the index of 3 radio frames is respectively 0,1,2.If be configured with 2 in some frames to find subframe, then corresponding frame index issues 2 times, repeatedly in a similar manner.Fig. 8 is a kind of 3 and finds that subframe is contained in the example in 2 radio frames, then in signaling, corresponding frame index is 0,1,1, and subframe numbers is respectively 3,3,8.

In another kind of configuration D2D resource area, the mode of the radio frames position that D2D subframe is corresponding is obtained by the formulae discovery of agreement, such as, suppose that the resource pool cycle is N, discovery number of sub-frames is M, the first radio frames position containing finding subframe is obtained according to (NmodM), assumption period original position is L, then the first radio frames position containing discovery subframe is (L+ (NmodM)).Position for step-length, is determined with (N/M) successively in the position of discovery radio frames below ,/represent the business getting division.

The configuration of D2D subframe position in D2D resource area, a kind of mode is configured by subframe numbers, is 3,3,8 as sub-frame configuration in Fig. 8 is respectively.

The another kind of configuration mode of subframe position is indicated by the bitmap of 10 bits, and corresponding 10 subframe position, " 1 " is expressed as discovery subframe, and " 0 " is not then.When such frame includes multiple D2D subframe, do not need to repeat to indicate frame index.Such as, 0001000000 represents that in radio frames, subframe 3 is configured to find subframe, and again such as, 0000000110 represents that in radio frames, subframe 7 and subframe 8 are configured to find subframe.

Equally, the configuration of subframe position also can be determined by agreement formulae discovery, similar with the configuration of radio frames, such as, suppose that the resource pool cycle is N, discovery number of sub-frames is M, determining containing being found in the radio frames of subframe, determine the position of discovery subframe according to (SFNmodNu), wherein Nu is the number of sub frames after removing descending sub frame in radio frames.

Can also be obtained the position of D2D resource group by agreement formulae discovery, such as determine according to formula (SFNmodNp)=offset, wherein SFN is radio frame number, and Np is D2D resource group interval, and offset is the resource group deviant of configuration.If formula represents that radio frame number equals the deviant configured to the value after the delivery of D2D resource group interval, then corresponding radio frames is the initial radio frames of D2D resource group, and a continuous K radio frames is D2D resource group, and K is the radio frames that D2D resource group comprises.Here K is not more than D2D resource group interval Np.Such as, supposing resource group deviant to be configured to 0, D2D communication resource group interval, to be configured to the radio frames that 10, D2D communication resource group comprises be 3.Subscriber equipment is according to formula (SFNmod10)=0, and the radio frames meeting formula is D2D communication resource group start frame, and continuous 3 radio frames form a D2D communication resource group.

In addition, above-mentioned formula can also calculate by the call number of radio frames in the D2D resource area cycle, and such formula becomes (SfIndexmodNp)=offset, and wherein SfIndex is the call number of radio frames within the D2D resource area cycle.An example as shown in Figure 9, suppose that the cycle finding resource area is 320ms, find that radio frame number (SFN) skew that the frequency domain resource bandwidth of resource area is Resource Block 0 ~ 49, discovery resource area original position is corresponding is 0, resource group deviant is configured to 0, find that resource group interval is configured to 10 radio frames, find that the radio frames that resource group comprises is 3, instruction finds that 10 of subframe position long bit bitmaps are 0000000010.

For the parameter configuration of D2D resource area, can also be realized by the mode of D2D resource area allocation list, allocation list comprises the fixed configurations not of the same race of D2D resource area parameter, the corresponding call number of each fixed configurations, and the call number described in network side only needs to indicate is to subscriber equipment.Subscriber equipment finds corresponding concrete configuration parameter according to described call number from described D2D resource area allocation list.An example is as shown in table 2.Find in the example of table 2 that resource area allocation list comprises 8 kinds of configuration parameters, correspondence 0 ~ 7 totally 8 call numbers respectively, suppose that the configuration parameter of network side determination call number 7 correspondence is the configuration parameter finding resource area, then call number 7 is handed down to subscriber equipment by configuration signal by network side.After subscriber equipment receives call number 7, by finding that the corresponding configuration parameter of resource area allocation list determination call number 7 is the corresponding configuration parameter finding resource area.
