First the application scenes to the present invention are described：
PD2DSCH subframes can be included in D2DSS subframes, can not also be included in D2DSS subframes, and the transmission cycle of PD2DSCH subframes and D2DSS subframes is not also restricted, and a point situation citing below is illustrated：
First, PD2DSCH subframes are integrally incorporated in D2DSS subframes：
The first situation：Refer to Fig. 1, with D2DSS transmission cycle (i.e. per the interval time transmitted twice) for 40ms, exemplified by the transmission cycle for the use of 4 D2DSS subframes being a PD2DSCH, in PD2DSCH transmission cycle 160ms, 4 D2DSS subframes can be transmitted, the continuous D2DSS subframes of two of which can be used to transmit PD2DSCH content, then in the two D2DSS subframes, also comprising PD2DSCH subframes.For example, in D2DSS subframes, two symbols are taken respectively by SD2DSS and PD2DSS, in the D2DSS subframes comprising PD2DSCH subframes, except the outer symbol for being taken and taken by D2D protection interval GAP by SD2DSS and PD2DSS, other symbols all by PD2DSCH takes.In such a scenario, in one PD2DSCH transmission cycle, in the symbol of D2DSS subframes for not including PD2DSCH subframes, 5 symbols are only occupied by SD2DSS, PD2DSS and GAP, remaining running time-frequency resource is all not used, then 9 symbols are there remains in normal cyclic prefix CP D2DSS subframes is not used.
Second of situation：Refer to Fig. 2, or with D2DSS transmission cycle (i.e. per the interval time transmitted twice) for 40ms, exemplified by the transmission cycle for the use of 4 D2DSS subframes being a PD2DSCH, but the PD2DSCH of a part is sent in each D2DSS subframes, for example, SD2DSS and PD2DSS takes 2 symbols respectively in each D2DSS subframes, and PD2DSCH takes 3 symbols, then 6 symbols there remains in normal cyclic prefix CP D2DSS subframes and be not used.
In both above situation, PD2DSCH subframes are all integrally incorporated in D2DSS subframes, included in each PD2DSCH subframes and PD2DSCH is included in D2DSS, each D2DSS subframes.
2nd, PD2DSCH subframes are partially contained in D2DSS subframes.
The third situation：Refer to Fig. 3, using the transmission cycle of D2DSS subframes as 40ms, exemplified by the transmission cycles of PD2DSCH subframes is 10ms, in equally spaced 4 subframes positioned at 40ms of PD2DSCH subframes, one of PD2DSCH subframes are included in D2DSS subframes, other PD2DSCH subframes individualisms.In such a scenario, in the 4 PD2DSCH subframes sent in 40ms, have in three PD2DSCH subframes and only include PD2DSCH, not comprising D2DSS, so wherein also thering is remaining symbol to be not used.
3rd, PD2DSCH subframes are not included in D2DSS subframes.
4th kind of situation：Refer to Fig. 4, using the transmission cycle of D2DSS subframes as 40ms, the transmission cycle of PD2DSCH subframes is exemplified by 10ms, PD2DSCH subframes are not located in D2DSS subframes, PD2DSCH is not included in each D2DSS subframes, do not include D2DSS subframes in each PD2DSCH subframes yet, so, there is remaining symbol to be not used in each subframe.
Example from above describes the application scenes of the embodiment of the present invention, it is appreciated that, D2DSS transmission cycle in the example above, PD2DSCH transmission cycle is all some specific examples, does not constitute limitation of the invention, for example, D2DSS transmission cycle can also be 80ms, and 160ms, D2DSS transmission cycle can also be 20ms, 10ms etc., is not construed as limiting herein.
And D2DSS subframes or PD2DSCH subframes can be normal cyclic prefix CP subframe or extended cyclic prefix CP subframe.Extended cyclic prefix CP and normal cyclic prefix CP is not With simply in 1ms subframe, the number difference of symbol, CP length difference, and the position where reference signal are different.The position of D2DSS or PD2DSCH occupancy symbol can also provide there are a variety of situations, are not construed as limiting herein according to actual conditions or agreement in each subframe, and citing below is illustrated：
It is illustrated in figure 5 the example of position one that D2DSS and PD2DSCH in extended cyclic prefix CP subframe takes symbol, wherein, PD2DSS takes the symbol 1 of the 1st and the 2nd time slot, SD2DSS takes the symbol 2 of the 1st and the 2nd time slot, PD2DSCH takes the symbol 0 of the 2nd time slot, symbol 3 and symbol 4.
It is illustrated in figure 6 the example of position one that D2DSS and PD2DSCH in normal cyclic prefix CP subframe takes symbol, wherein, PD2DSS takes the symbol 2 of the 1st and the 2nd time slot, SD2DSS takes the symbol 3 of the 1st and the 2nd time slot, PD2DSCH takes the symbol 1 of the 2nd time slot, symbol 4 and symbol 5.
It is illustrated in figure 7 another example of position that D2DSS and PD2DSCH in extended cyclic prefix CP subframe takes symbol, wherein, PD2DSS takes the symbol 1 of the 1st and the 2nd time slot, SD2DSS takes the symbol 3 of the 1st and the 2nd time slot, PD2DSCH takes the symbol 0 of the 2nd time slot, symbol 2 and symbol 4.
It is illustrated in figure 8 another example of position that D2DSS and PD2DSCH in normal cyclic prefix CP subframe takes symbol, wherein, PD2DSS takes the symbol 2 of the 1st and the 2nd time slot, SD2DSS takes the symbol 4 of the 1st and the 2nd time slot, PD2DSCH takes the symbol 1 of the 2nd time slot, symbol 3 and symbol 5.
It is appreciated that, the known sequence inherently generated due to D2DSS by reference signal, so it does not need demodulated reference signal, and the transmission of PD2DSCH the insides is information, it is that needs are to be determined for receiver, when PD2DSCH subframes are located in D2DSS subframes, PD2DSCH can regard the D2DSS in subframe as demodulated reference signal, but when in the PD2DSCH subframes of individualism, in the subframe for not including D2DSS namely, need to load single demodulated reference signal to be demodulated PD2DSCH, that is, in the PD2DSCH subframes for not including D2DSS, demodulated reference signal dedicated for demodulation PD2DSCH also takes up partial symbols.And include in D2DSS PD2DSCH subframes, PD2DSCH can also use special demodulated reference signal using synchronizing signal as demodulated reference signal, be not construed as limiting herein.
It is illustrated in figure 9 in the normal cyclic prefix CP PD2DSCH subframes for not including D2DSS PD2DSCH and DMRS takes an example of character position, wherein, PD2DSCH takes the symbol 4 and symbol 5 of the 2nd time slot, and DMRS takes the symbol 3 of the 2nd time slot.Now the bandwidth of occupancy of the DMRS here on the symbol of place is at least otherwise less than the bandwidth of PD2DSCH channel occupancies.
PD2DSCH and DMRS takes an example of character position in the PD2DSCH subframes not include D2DSS extended cyclic prefix CP as shown in Figure 10, wherein, PD2DSCH takes the symbol 3 and symbol 4 of the 2nd time slot, and DMRS takes the symbol 2 of the 2nd time slot.
It is understood that above-mentioned is only some examples that PD2DSCH or D2DSS take character position in PD2DSCH subframes or D2DSS subframes, according to the actual requirements or agreement regulation, there can also be more modes taken to character position, be not construed as limiting herein.
For example only for master sync signal in synchronizing signal and from the position in synchronizing signal, can just there are more kinds of modes, and the position of wherein master sync signal and the symbol taken from synchronizing signal can be exchanged, and master sync signal is identical with the interval from synchronizing signal in former and later two time slots：
When the synchronizing signal subframe is extended cyclic prefix CP synchronizing signal subframe, symbol 1 and symbol 2 in the master sync signal and described former and later two time slots for taking the synchronizing signal subframe from synchronizing signal；
Or, when the synchronizing signal subframe is extended cyclic prefix CP synchronizing signal subframe, symbol 1 and symbol 3 in the master sync signal and described former and later two time slots for taking the synchronizing signal subframe from synchronizing signal；
Or, when the synchronizing signal subframe is extended cyclic prefix CP synchronizing signal subframe, symbol 0 and symbol 1 in the master sync signal and the previous time slot for taking the synchronizing signal subframe from synchronizing signal, and take the symbol 3 and symbol 4 in the latter time slot；
Or, when the synchronizing signal subframe is normal cyclic prefix CP synchronizing signal subframe, symbol 2 and symbol 3 in the master sync signal and described former and later two time slots for taking the synchronizing signal subframe from synchronizing signal；
Or, when the synchronizing signal subframe is normal cyclic prefix CP synchronizing signal subframe, symbol 2 and symbol 4 in the master sync signal and described former and later two time slots for taking the synchronizing signal subframe from synchronizing signal；
Or, when the synchronizing signal subframe is normal cyclic prefix CP synchronizing signal subframe, in the master sync signal and the previous time slot for taking the synchronizing signal subframe from synchronizing signal Symbol 0 and symbol 1, and take symbol 4 and symbol 5 in the latter time slot；
And synchronization control channel can take 3 or 4 symbols different from the synchronizing signal position in synchronizing signal subframe.
Except above-mentioned example, there can also be more occupancy modes to symbol in synchronizing signal subframe and/or synchronization control channel subframe, be not construed as limiting herein.
Signaling method in the embodiment of the present invention is described below.
It can be seen that in the case of symbol is occupied from above-mentioned PD2DSCH subframes or D2DSS subframes, there are many symbols to be not used in PD2DSCH subframes or D2DSS subframes, waste so is caused to the running time-frequency resource of subframe, therefore, it is possible to use the running time-frequency resource of this part.
Referring to signaling method one embodiment in Figure 11, the embodiment of the present invention includes：
1101st, transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe, and the synchronizing signal subframe includes synchronizing signal, and the synchronization control channel subframe includes synchronization control channel；
Transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe (D2DSS subframes) and/or synchronization control channel subframe (PD2DSCH subframes).
It is appreciated that, the transmitting end equipment is the emitter of data, but the not necessarily emitter of synchronisation source (i.e. D2DSS or PD2DSCH), if the transmitting end equipment is synchronisation source emitter, the D2DSS or PD2DSCH that character position is then taken in D2DSS subframes and/or PD2DSCH subframes can be launched by the transmitting end equipment oneself, if the transmitting end equipment is not synchronisation source emitter, the D2DSS or PD2DSCH of character position are then taken in D2DSS subframes and/or PD2DSCH subframes to be launched by others are the emitters of synchronisation source, it is not construed as limiting herein.
1102nd, the transmitting end equipment loads data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource；
Transmitting end equipment is determined in synchronizing signal subframe and/or synchronization control channel subframe after unappropriated resource, and data are loaded in unappropriated resource in the synchronizing signal subframe and/or synchronization control channel subframe.
It is appreciated that, unappropriated resource can be used for D2D links in synchronizing signal subframe and/or synchronization control channel subframe, cellular link can also be used for, it is then corresponding, the data loaded in unappropriated resource can be the data of D2D links, can also be the data of cellular link, herein not It is construed as limiting.
1103rd, the data of loading are sent to receiving device by the transmitting end equipment.
The transmitting end equipment is loaded after data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource, and the data loaded in the synchronizing signal subframe and/or synchronization control channel subframe are sent into receiving device.
Transmitting end equipment first determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe in the embodiment of the present invention, in the synchronizing signal subframe and/or synchronization control channel subframe data are loaded in unappropriated resource, the data being carried in synchronizing signal subframe and/or synchronization control channel subframe are sent to receiving device by transmitting end equipment again, so, unappropriated resource in D2D synchronizing signal subframe is effectively make use of, utilization rate of the system to resource is improved.
The data transfer neutralization used separately below unappropriated resource in D2D links is used to be described in the data transfer of cellular link：
First, the data transfer for D2D links.
If Figure 12 is that unappropriated resource uses an application scenarios in D2D links, wherein base station equipment may have, it can also be not present, but can at least (provided in Figure 12 be an emitter schematic diagram) have D2D transmitting end equipment and several D2D receiving device, transmitting end equipment and receiving device are D2D terminal, as shown in Figure 12, D2DUE1 is transmitting end equipment, and D2DUE2 and D2DUE3 are receiving device.
It is appreciated that, the data being carried in unappropriated resource need demodulated reference signal and could demodulated, and be contemplated that when loading demodulated reference signal, transmitting end equipment in the embodiment of the present invention must be the emitter of data, but the not necessarily emitter of synchronisation source, whether the transmitting end equipment is the emitter of synchronisation source also to the demodulated reference signals of the data of loading by certain influence, in addition, the bandwidth of the data of loading is likely larger than synchronizing signal or the bandwidth of synchronization control channel, synchronizing signal or the bandwidth of synchronization control channel may also be less than, the demodulated reference signal of its data to loading also has a certain impact, divide a variety of situations that the signaling method in the embodiment of the present invention is specifically described below：
1st, transmitting end equipment is the emitter of data, is also the emitter of synchronisation source.
1.1st, the bandwidth of the data of loading is in synchronizing signal or the bandwidth of synchronization control channel：
In this case, because transmitting end equipment is also the emitter of synchronisation source, therefore, the data being carried in untapped resource can use the synchronizing signal that transmitting end equipment is sent as demodulated reference signal, i.e., When there is synchronizing signal in synchronizing signal subframe and/or synchronization control channel subframe, transmitting end equipment need not individually load the demodulated reference signal for the data demodulation for being exclusively used in loading in unappropriated resource, as shown in any of Fig. 5 to Fig. 8, there is synchronizing signal in synchronizing signal subframe and/or synchronization control channel subframe, it is not necessary to load the demodulated reference signal dedicated for demodulating data；As shown in fig. 9 or 10, not comprising in having a synchronization control channel subframe of synchronizing signal, transmitting end equipment is accomplished by individually loading a demodulated reference signal for synchronization control channel originally, because transmitting end equipment is also the emitter of synchronisation source, therefore, can also using the demodulated reference signal demodulated for synchronization control channel as the data of loading demodulated reference signal, also without individually loading is exclusively used in the demodulated reference signal of the data demodulation of loading in unappropriated resource, exemplified by shown in Figure 13, for an example schematic of the bandwidth in synchronizing signal or the bandwidth of synchronization control channel of the data of loading.
1.2, the bandwidth of the data of loading beyond synchronizing signal or synchronization control channel bandwidth：
Referring to another embodiment of signaling method in Figure 14, the embodiment of the present invention includes：
1401st, transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe；
Exemplified by shown in Figure 15, exceed synchronizing signal or one example schematic diagram of bandwidth of synchronization control channel for the bandwidth of the data of loading, in this case, in synchronizing signal subframe and/or synchronization control channel subframe, prepare the bandwidth of data of loading beyond synchronizing signal or the bandwidth of synchronization control channel, therefore, when determining unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe, the part outside the bandwidth of synchronizing signal or synchronization control channel is also unappropriated resource.
1402nd, the transmitting end equipment is in the synchronizing signal subframe and/or synchronization control channel subframe, on the position outside the bandwidth of the synchronizing signal or synchronization control channel, loads the 5th reference signal.
And due to there is no demodulated reference signal outside synchronizing signal in D2D synchronizing signal subframe and/or synchronization control channel subframe or the bandwidth of synchronization control channel, therefore, in order to be able to which the data of the loading to after are demodulated, transmitting end equipment is in the synchronizing signal subframe and/or synchronization control channel subframe, on position outside the synchronizing signal or the bandwidth of synchronization control channel, the 5th reference signal is loaded.DMRS5 is an example of the 5th reference signal loaded in as shown in figure 15.
In actual applications, in the following manner can be included by loading the 5th reference signal specific method：
1st, the transmitting end equipment is in the synchronizing signal subframe and/or synchronization control channel subframe, generates the demodulation reference sequence in the bandwidth of data, by the demodulation reference sequence in the bandwidth of the data with synchronizing signal Or the part of the bandwidth overlay of control channel is deleted, and the remaining part of demodulation reference sequence is put and generates the 5th reference signal on a corresponding position；
2nd, the transmitting end equipment is in the synchronizing signal subframe and/or synchronization control channel subframe in the bandwidth of data, and the nonoverlapping position of bandwidth with synchronizing signal or synchronization control channel generates the 5th reference signal.
Both the above mode, which can choose any one kind of them, generates the 5th reference signal, it is to be understood that also has others to generate the mode of the 5th reference signal, is not construed as limiting herein.
1403rd, the transmitting end equipment loads data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource；
Now, unappropriated resource includes subframe, symbol or the bandwidth not taken by the synchronizing signal and synchronization control channel, GAP and demodulated reference signal in synchronizing signal subframe and/or synchronization control channel subframe.As shown in figure 15, the bandwidth of the data of loading is beyond synchronizing signal or the bandwidth of synchronization control channel.
1404th, the data of loading are sent to receiving device by the transmitting end equipment.
The transmitting end equipment is loaded after data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource, and the data loaded in the synchronizing signal subframe and/or synchronization control channel subframe are sent into receiving device.
In the embodiment of the present invention, when the bandwidth of the data of loading exceeds the bandwidth of synchronizing signal or synchronization control channel, transmitting end equipment is in the synchronizing signal subframe and/or synchronization control channel subframe, on position outside the synchronizing signal or the bandwidth of synchronization control channel, load the 5th reference signal, so just data can be also loaded outside synchronizing signal or the bandwidth of synchronization control channel, greatly make use of the running time-frequency resource in synchronizing signal subframe and/or synchronization control channel subframe.
In above example, as shown in figure 15, when the bandwidth of data is beyond synchronizing signal or the bandwidth of synchronization control channel, the position relationship of the bandwidth and synchronizing signal of data or the bandwidth of synchronization control channel may have two kinds of situations, a kind of is that synchronizing signal or the bandwidth of synchronization control channel are included in centre by the bandwidth of data, one end of one end of another bandwidth for being data and synchronizing signal or the bandwidth of synchronization control channel is to it, and the other end has the bandwidth of partial data in the outside of synchronizing signal or the bandwidth of synchronization control channel.In actual applications, it should preferential：When the band of data is wider than the bandwidth of synchronizing signal or synchronization control channel, the bandwidth of the data is not across synchronizing signal or the bandwidth of synchronization control channel；When the bandwidth of data is less than the bandwidth of synchronizing signal or synchronous control signal, the bandwidth of the data the synchronizing signal or the bandwidth of synchronization control channel it It is interior.
2nd, transmitting end equipment is the emitter of data, but is not necessarily the emitter of synchronisation source.
In this case, transmitting end equipment can be the emitter of synchronisation source, may not be the emitter of synchronisation source, and the reference signal that the data of loading are all individually loaded using transmitting terminal data is divided into two ways as demodulated reference signal：Time-division or superposition.
2.1st, demodulated reference signal is loaded by the way of the time-division：
Referring to another embodiment of signaling method in Figure 16, the embodiment of the present invention includes：
1601st, transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe, and the synchronizing signal subframe includes synchronizing signal, and the synchronization control channel subframe includes synchronization control channel；
Transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe (D2DSS subframes) and/or synchronization control channel subframe (PD2DSCH subframes).
1602nd, when not including synchronization control channel in the synchronizing signal subframe, the transmitting end equipment is not taken and with loading the first reference signal on the symbol of the synchronizing signal diverse location in the synchronizing signal subframe by synchronizing signal；
For example shown in Figure 17, for an example schematic of the first reference signal is loaded by the way of the time-division in the synchronizing signal subframe for not including synchronization control channel, the transmitting end equipment is not taken and with loading the first reference signal DMRS1 on the symbol of the synchronizing signal diverse location in the synchronizing signal subframe by synchronizing signal.
First reference signal is carried on the symbol with synchronizing signal diverse location, the interference to synchronizing signal can be prevented.
1603rd, when not including synchronizing signal in the synchronization control channel subframe, the transmitting end equipment is not in synchronized control channel occupancy and with loading the second reference signal on the symbol of the synchronization control channel diverse location in the synchronization control channel subframe；
For example shown in Figure 18, for an example schematic of the second reference signal is loaded by the way of the time-division in the synchronization control channel subframe for not including synchronizing signal, the transmitting end equipment is not taken and with loading the second reference signal DMRS2 on the symbol of the synchronizing signal diverse location in the synchronizing signal subframe by synchronizing signal.
It is understood that in such case, when the transmitting end equipment is synchronisation source emitter, loading Second reference signal can be simultaneously as the demodulated reference signal of synchronization control channel, when the transmitting end equipment is not synchronisation source emitter, the partial symbols of the synchronization control channel subframe are also dedicated to demodulate shared by the demodulated reference signal of the synchronization control channel.
1604th, when in the synchronizing signal subframe or synchronization control channel subframe both include synchronizing signal, when also including synchronization control channel, the transmitting end equipment is in the synchronizing signal subframe or synchronization control channel subframe, do not taken by synchronizing signal and synchronization control channel, and with loading the 3rd reference signal on the symbol of the synchronizing signal and synchronization control channel diverse location.
For example shown in Figure 19, both to include synchronizing signal, also an example schematic of the 3rd reference signal is loaded in synchronizing signal subframe or synchronization control channel subframe including synchronization control channel by the way of the time-division, the transmitting end equipment is in the synchronizing signal subframe, do not taken by synchronizing signal and synchronization control channel, and with loading the 3rd reference signal DMRS3 on the symbol of the synchronizing signal and synchronization control channel diverse location.
It is understood that the different situations for the subframe that step 1602 is sent to step 1604 according to transmitting end equipment, can choose at least one step therein, not necessarily perform all steps, do not limit herein.
It should be noted that when the band of data is wider than the bandwidth of synchronizing signal or synchronization control channel, the first reference signal of loading, the second reference signal or the 3rd reference signal are identical with the bandwidth of data.
Wherein, the first reference signal, the second reference signal or the 3rd reference signal are generated by the sequence uniquely determined respectively, and its corresponding sequence generating method includes：
In the bandwidth of the data generate, or, in the bandwidth where synchronizing signal or synchronization control channel formation sequence Part I, and in remaining bandwidth formation sequence Part II.
1605th, the transmitting end equipment loads data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource；
Transmitting end equipment is determined in synchronizing signal subframe and/or synchronization control channel subframe after unappropriated resource, and data are loaded in unappropriated resource in the synchronizing signal subframe and/or synchronization control channel subframe.
Now unappropriated resource includes subframe, symbol or the bandwidth not taken by synchronizing signal, synchronization control channel, GAP, the first reference signal, the second reference signal and the 3rd reference signal in synchronizing signal subframe and/or synchronization control channel subframe.
1606th, the data of loading are sent to receiving device by the transmitting end equipment.
The transmitting end equipment is loaded after data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource, and the data loaded in the synchronizing signal subframe and/or synchronization control channel subframe are sent into receiving device.
The embodiment of the present invention loads the first reference signal, the second reference signal or the 3rd reference signal using the method for time-division in synchronizing signal subframe and/or synchronization control channel subframe, it is ensured that the data of loading can be demodulated smoothly.
2.1st, demodulated reference signal is loaded by the way of superposition：
Referring to another embodiment of signaling method in Figure 20, the embodiment of the present invention includes：

For example shown in Figure 21, an example schematic of the 4th reference signal of loading is superimposed on the symbol that synchronizing signal takes for transmitting end equipment, in the synchronizing signal subframe and/or synchronization control channel subframe of synchronizing signal is included, the transmitting end equipment is on the symbol that synchronizing signal takes, the 4th reference signal DMRS4 of superposition loading.
It is appreciated that, not comprising in having a synchronization control channel subframe of synchronizing signal, if the transmitting end equipment is synchronisation source emitter, then the transmitting end equipment can load the 4th reference signal not being in synchronized control on channel occupancy and symbol with the synchronization control channel diverse location, if the transmitting end equipment is not synchronisation source emitter, then the transmitting end equipment can be in the synchronization control channel subframe, on the symbol that the demodulated reference signal of synchronization control channel takes, superposition the 4th reference signal of loading.
It should be noted that when the band of data is wider than the bandwidth of synchronizing signal or synchronization control channel, the bandwidth of the 4th reference signal of loading is identical with the bandwidth of data.
In actual applications, the part signal in synchronizing signal subframe, such as SD2DSS will carry out back-off when transmission, therefore just can will be used for the transmitting of demodulated reference signal in the power of rollback.That is, will can be launched on the symbol where being superimposed upon synchronizing signal in demodulated reference signal.I.e. demodulated reference signal is superimposed upon on the same symbol in synchronizing signal subframe using different power from synchronizing signal and sent out Send.Wherein demodulated reference signal is used for realizing the demodulation of D2D data, and synchronizing signal is used for the synchronization of D2D receivers.
2003rd, the transmitting end equipment loads data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource；
Transmitting end equipment is determined in synchronizing signal subframe and/or synchronization control channel subframe after unappropriated resource, and data are loaded in unappropriated resource in the synchronizing signal subframe and/or synchronization control channel subframe.

2004th, the data of loading are sent to receiving device by the transmitting end equipment.
The transmitting end equipment is loaded after data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource, and the data loaded in the synchronizing signal subframe and/or synchronization control channel subframe are sent into receiving device.
In the embodiment of the present invention, 4th reference signal is superimposed upon to the demodulated reference signal in synchronizing signal as data, save the position of symbol in synchronizing signal subframe and/or synchronization control channel subframe, add can load be data time-domain resource, improve the utilization rate to resource.
In actual applications, except being used alone in above-mentioned various situations to demodulated reference signal and the load mode of data, before loading data, sending ending equipment can also first judge whether each synchronisation source quality inspection is defined co-sited (QCL), select different modes to be demodulated the loading of reference signal and data further according to judged result.So-called QCL refers to：Signal from multiple independent emitters, the corresponding parameter of channel (the corresponding maximum delay extension of such as channel that they are undergone, peak frequency extension or maximum doppler frequency value etc.) difference is smaller from the point of view of receiver, can approx be counted as coming from the signal of same website.The method that emitter judges is that before transmitting data, the D2DSS of all synchronisation sources in reception group is estimated and analyzed to their channel, and the channel if all of synchronisation source is approximately uniform, then it is considered that meeting QCL condition.QCL can also be obtained in addition to it can be obtained by launching machine testing by way of network signal is notified.Network can be by obtaining UE channel information on cellular link, or reports by UE the channel information of each synchronisation source oneself detected, so that it is determined that whether each synchronisation source in current group is QCL.
Referring to another embodiment of signaling method in Figure 22, the embodiment of the present invention includes：
2201st, transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe, and the synchronizing signal subframe includes synchronizing signal, and the synchronization control channel subframe includes synchronization control channel；
2202nd, the transmitting end equipment judges the co-sited QCL that whether is defined between each synchronisation source in discovery group；
The transmitting end equipment judges the co-sited QCL that whether is defined between each synchronisation source in discovery group, the QCL is used to represent that the signal that multiple transmitting end equipments are sent in the discovery group can be approximately the signal for coming from same website, and the synchronisation source includes the transmitting end equipment and receiving device in the discovery group；
2203rd, when it is determined that in the discovery group between each synchronisation source be QCL when, do not load demodulated reference signal in the synchronizing signal subframe or synchronization control channel subframe, or the 5th reference signal is loaded on the position outside the synchronizing signal or the bandwidth of synchronization control channel.
It is understood that when it is determined that between each synchronisation source being QCL in discovery group, can also determine which kind of mode to perform the operation of subsequent load demodulated reference signal using according to various situations.
For example, the bandwidth of synchronizing signal or the bandwidth of synchronization control channel and data to be loaded in synchronizing signal subframe or synchronization control channel subframe can be compared, when the bandwidth of the data with loading is in synchronizing signal or the bandwidth of synchronization control channel, can no longer in the synchronizing signal subframe or synchronization control channel subframe loading be exclusively used in demodulation loading data demodulated reference signal, because when having synchronizing signal in the synchronizing signal subframe or synchronization control channel subframe, can be using demodulated reference signal of the synchronizing signal as the data of loading, when there is no synchronizing signal, certain demodulated reference signal having for demodulating synchronization control channel, can using the demodulated reference signal of the demodulation synchronization control channel as the data of loading demodulated reference signal.And when the bandwidth of data to be loaded is beyond synchronizing signal or the bandwidth of synchronization control channel, the data loaded outside synchronizing signal or the bandwidth of synchronization control channel just can not be used as demodulated reference signal by the use of the demodulated reference signal of synchronizing signal or synchronization control channel, now, it is necessary to which loading is exclusively used in the demodulated reference signal of the data of demodulation loading outside synchronizing signal or the bandwidth of synchronization control channel.

It is understood that when it is determined that between each synchronisation source being not QCL in discovery group, can also determine which kind of mode to perform the operation of subsequent load demodulated reference signal using according to various situations.
For example, if desired more data are loaded, data are loaded using more time-domain resources, demodulated reference signal is loaded in synchronizing signal subframe or synchronization control channel subframe in the mode that can choose superposition, can so save partial symbols resource to load data：The 4th reference signal of superposition loading on the symbol that synchronizing signal takes in the synchronizing signal subframe and/or synchronization control channel subframe；If it is desired to ensure that demodulated reference signal is noiseless from each other, ensureing the accuracy of demodulation, demodulated reference signal can be loaded on unappropriated symbol by the way of the time-division：Do not taken in the synchronizing signal subframe for not including synchronization control channel by synchronizing signal and load the first reference signal on the symbol with the synchronizing signal diverse location, it is not in synchronized control in the synchronization control channel subframe for not including synchronizing signal on channel occupancy and symbol with the synchronization control channel diverse location and loads the second reference signal, in synchronizing signal subframe or synchronization control channel subframe both including synchronizing signal or including synchronization control channel, do not taken and by synchronizing signal and synchronization control channel with loading the 3rd reference signal on the symbol of the synchronizing signal and synchronization control channel diverse location.

If Figure 24 is that unappropriated resource uses an application scenarios in cellular link, wherein, unappropriated resource transmission cellular data in the synchronizing signal subframe and/or synchronization control channel subframe is used between base station and cellular terminal, and occupied resource in the synchronizing signal subframe and/or synchronization control channel subframe is used between cellular terminal and cellular terminal, send the synchronizing signal and/or synchronization control channel in D2D links, for example shown in Figure 24, between cellular terminal UE4 and base station equipment cellular link data are sent using unappropriated resource, and the synchronizing signal and/or synchronization control channel in occupied resource transmission D2D links are used between cellular terminal UE1 and UE2 and UE3.
In this application scenarios, the up scene and descending scene of data can be divided into again.
1st, in the descending scene of data：
Base station loads data in unappropriated resource and re-sends to cellular terminal, and base station is the sending ending equipment in the embodiment of the present invention, and cellular terminal is the receiving device in the embodiment of the present invention.
In this scene, base station loads data and the specific steps of demodulated reference signal in synchronizing signal subframe or synchronization control channel subframe in unappropriated resource, base station can be regard as transmitting end equipment, refering to transmitting end equipment loading data in previous embodiments and the specific steps of demodulated reference signal, with it is above-mentioned in the scene of D2D links it is similar, do not repeat herein.
2nd, in the up scene of data：
Cellular terminal loads data in unappropriated resource and re-sends to base station, and cellular terminal is the sending ending equipment in the embodiment of the present invention, and base station is the receiving device in the embodiment of the present invention.
It is with data and the difference of demodulated reference signal described in the scene in above-mentioned D2D links, cellular terminal does not know whether the subframe of oneself data to be sent is synchronizing signal subframe or synchronization control channel subframe, and base station is known, need first to receive a configured information of base station transmission to determine whether the subframe currently launched is synchronizing signal subframe or synchronization control channel subframe, when the first configured information for receiving base station transmission, when to indicate the subframe that the cellular terminal currently launches be synchronizing signal subframe and/or synchronization control channel subframe, the step of performing unappropriated resource in follow-up determination D2D synchronizing signal subframe and/or synchronization control channel subframe again, subsequent step is similar with the detailed process in D2D links, illustrated below by taking several embodiments as an example：
Referring to another embodiment of signaling method in Figure 25, the embodiment of the present invention includes：
2501st, transmitting end equipment receives the first configured information that receiving device is sent, first configured information For indicating whether the subframe that the transmitting end equipment is currently launched is synchronizing signal subframe and/or synchronization control channel subframe；
In the present embodiment, the transmitting end equipment is cellular terminal, and the receiving device is base station.First configured information can be the information that explicit signaling is indicated or incidentally in the information of specific reference signals.First configured information will at least include two states, i.e., when transmission：Instruction is synchronizing signal subframe and/or synchronization control channel subframe；Instruction is not synchronizing signal subframe and/or synchronization control channel subframe.
2502nd, when it is synchronizing signal subframe and/or synchronization control channel subframe that first configured information, which indicates the subframe currently launched, transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe, the synchronizing signal subframe includes synchronizing signal, and the synchronization control channel subframe includes synchronization control channel；
2503rd, the transmitting end equipment loads data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource；
Transmitting end equipment is determined in synchronizing signal subframe and/or synchronization control channel subframe after unappropriated resource, and data are loaded in unappropriated resource in the synchronizing signal subframe and/or synchronization control channel subframe.
2504th, the data of loading are sent to receiving device by the transmitting end equipment.
The transmitting end equipment is loaded after data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource, and the data loaded in the synchronizing signal subframe and/or synchronization control channel subframe are sent into receiving device.
It is appreciated that, transmitting end equipment can only send the symbol for being loaded with data, and demodulate the data demodulated signal symbol to receiving device, complete synchronizing signal subframe and/or synchronization control channel subframe can also be sent to receiving device, be not construed as limiting herein.
In the embodiment of the present invention, when sending ending equipment is cellular terminal, need first to receive the first configured information that base station is sent, when it is synchronizing signal subframe and/or synchronization control channel subframe that first configured information, which determines the subframe currently launched, the step of just performing unappropriated resource in the determination synchronizing signal subframe and/or synchronization control channel subframe in the embodiment of the present invention, so that unappropriated resource can be used for the data for transmitting cellular link in synchronizing signal subframe and/or synchronization control channel subframe, the use scope of unappropriated resource has been widened.
Again by taking the embodiment in the data for loading D2D links shown in Figure 16 as an example, loading reference signal it It is preceding, it is necessary to first receive the first configured information, detailed process, which can change, to be as follows：
1st, transmitting end equipment receives the first configured information that receiving device is sent, and first configured information is used to indicate whether the subframe that the transmitting end equipment is currently launched is synchronizing signal subframe and/or synchronization control channel subframe；
In the present embodiment, the transmitting end equipment is cellular terminal, and the receiving device is base station.First configured information can be the information that explicit signaling is indicated or incidentally in the information of specific reference signals.First configured information will at least include two states, i.e., when transmission：Instruction is synchronizing signal subframe and/or synchronization control channel subframe；Instruction is not synchronizing signal subframe and/or synchronization control channel subframe.
2nd, when it is synchronizing signal subframe and/or synchronization control channel subframe that first configured information, which indicates the subframe currently launched, transmitting end equipment determines unappropriated resource in D2D synchronizing signal subframe and/or synchronization control channel subframe, the synchronizing signal subframe includes synchronizing signal, and the synchronization control channel subframe includes synchronization control channel；
3rd, when not including synchronization control channel in the synchronizing signal subframe, the transmitting end equipment is not taken and with loading the first reference signal on the symbol of the synchronizing signal diverse location in the synchronizing signal subframe by synchronizing signal；
For example shown in Figure 17, for an example schematic of the first reference signal is loaded by the way of the time-division in the synchronizing signal subframe for not including synchronization control channel, the transmitting end equipment is not taken and with loading the first reference signal DMRS1 on the symbol of the synchronizing signal diverse location in the synchronizing signal subframe by synchronizing signal.
First reference signal is carried on the symbol with synchronizing signal diverse location, the interference to synchronizing signal can be prevented.
4th, when not including synchronizing signal in the synchronization control channel subframe, the transmitting end equipment is not in synchronized control channel occupancy and with loading the second reference signal on the symbol of the synchronization control channel diverse location in the synchronization control channel subframe；
For example shown in Figure 18, for an example schematic of the second reference signal is loaded by the way of the time-division in the synchronization control channel subframe for not including synchronizing signal, the transmitting end equipment is not taken and with loading the second reference signal DMRS2 on the symbol of the synchronizing signal diverse location in the synchronizing signal subframe by synchronizing signal.
It is understood that in such case, when the transmitting end equipment is synchronisation source emitter, loading Second reference signal can be simultaneously as the demodulated reference signal of synchronization control channel, when the transmitting end equipment is not synchronisation source emitter, the partial symbols of the synchronization control channel subframe are also dedicated to demodulate shared by the demodulated reference signal of the synchronization control channel.
5th, when in the synchronizing signal subframe or synchronization control channel subframe both include synchronizing signal, when also including synchronization control channel, the transmitting end equipment is in the synchronizing signal subframe or synchronization control channel subframe, do not taken by synchronizing signal and synchronization control channel, and with loading the 3rd reference signal on the symbol of the synchronizing signal and synchronization control channel diverse location.
For example shown in Figure 19, both to include synchronizing signal, also an example schematic of the 3rd reference signal is loaded in synchronizing signal subframe or synchronization control channel subframe including synchronization control channel by the way of the time-division, the transmitting end equipment is in the synchronizing signal subframe, do not taken by synchronizing signal and synchronization control channel, and with loading the 3rd reference signal DMRS3 on the symbol of the synchronizing signal and synchronization control channel diverse location.
It is understood that the different situations for the subframe that step 3 is sent to step 5 according to transmitting end equipment, can choose at least one step therein, not necessarily perform all steps, do not limit herein.
It should be noted that when the band of data is wider than the bandwidth of synchronizing signal or synchronization control channel, the first reference signal of loading, the second reference signal or the 3rd reference signal are identical with the bandwidth of data.
Wherein, the first reference signal, the second reference signal or the 3rd reference signal are generated by the sequence uniquely determined respectively, and its corresponding sequence generating method includes：
In the bandwidth of the data generate, or, in the bandwidth where synchronizing signal or synchronization control channel formation sequence Part I, and in remaining bandwidth formation sequence Part II.
6th, the transmitting end equipment loads data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource；
Transmitting end equipment is determined in synchronizing signal subframe and/or synchronization control channel subframe after unappropriated resource, and data are loaded in unappropriated resource in the synchronizing signal subframe and/or synchronization control channel subframe.
Now unappropriated resource includes subframe, symbol or the bandwidth not taken by synchronizing signal, synchronization control channel, GAP, the first reference signal, the second reference signal and the 3rd reference signal in synchronizing signal subframe and/or synchronization control channel subframe.
7th, the data of loading are sent to receiving device by the transmitting end equipment.
The transmitting end equipment is loaded after data in the synchronizing signal subframe and/or synchronization control channel subframe in unappropriated resource, and the data loaded in the synchronizing signal subframe and/or synchronization control channel subframe are sent into receiving device.

First, the data that the receiving device is received are the data of cellular link.
In this application scenarios, the up scene and descending scene of data can be divided into again.
1st, in the descending scene of data：
Base station loads data in unappropriated resource and re-sends to cellular terminal, and base station is the sending ending equipment in the embodiment of the present invention, and cellular terminal is the receiving device in the embodiment of the present invention.
In this scene, it is with the difference of the parsing data in the scene of above-mentioned D2D links, cellular terminal does not know whether the subframe that oneself is received is synchronizing signal subframe or synchronization control channel subframe, need first to receive the second configured information that base station is sent, second configured information is used to indicate whether the currently received subframe of cellular link terminal is synchronizing signal subframe or synchronization control channel subframe, when cellular link terminal according to second configured information to determine currently received subframe be synchronizing signal subframe or synchronous control signal subframe when, the step of performing the data being carried in synchronizing signal subframe and/or synchronization control channel subframe of receipt of subsequent transmitting end equipment transmission again, it is appreciated that, receipt of subsequent data and parsing the step of with received in embodiments above be D2D links data detailed process it is similar, illustrated below by taking one embodiment as an example：
Referring to another embodiment of signal acceptance method in Figure 32, the embodiment of the present invention includes：
3201st, the second configured information that receiving device receiving end/sending end equipment is sent, second configured information is used to indicate whether the currently received subframe of the receiving device is synchronizing signal subframe and/or synchronization control channel subframe；
In the present embodiment, the receiving device is cellular link UE, and the sending ending equipment is base station.
3202nd, when it is synchronizing signal and/or synchronization control channel subframe subframe that second configured information, which indicates currently received subframe, receiving device receives the data being carried in synchronizing signal subframe and/or synchronization control channel subframe that transmitting end equipment is sent, the synchronizing signal subframe is D2D synchronizing signal subframe, and the synchronization control channel subframe is D2D synchronization control channel subframe；

In the embodiment of the present invention, when receiving device is cellular link terminal, when sending ending equipment is base station, the second configured information that receiving device elder generation receiving end/sending end equipment is sent, when it is synchronizing signal and/or synchronization control channel subframe subframe that second configured information, which indicates currently received subframe, subsequent step is just performed again, so that unappropriated resource can be used for the data for transmitting cellular link in synchronizing signal subframe and/or synchronization control channel subframe, the use scope of unappropriated resource has been widened.
It is appreciated that, when receiving device is cellular link terminal, as long as the step of in each embodiment of the data of above-mentioned reception D2D links plus the second configured information of step 3201 receiving end/sending end equipment transmission, can apply in this scene, not repeat herein.
2nd, in the up scene of data：
Cellular terminal loads data in unappropriated resource and re-sends to base station, and cellular terminal is the sending ending equipment in the embodiment of the present invention, and base station is the receiving device in the embodiment of the present invention.
In such case, base station parses the specific steps for being carried in synchronizing signal subframe and/or the data in synchronization control channel subframe, with base station can be regard as receiving device, the specific steps of the data in synchronizing signal subframe and/or synchronization control channel subframe are carried in refering to reception end plug red packet parsing in each embodiment for the data for above receiving D2D links, it is similar with the scene of the data of above-mentioned reception D2D links, do not repeat herein.
It should be noted that in the various embodiments described above, during the data during receiving device parses the synchronizing signal subframe and/or synchronization control channel subframe, it is also desirable to carry out rate-matched to the synchronizing signal subframe and/or synchronization control channel subframe.
Relevant indicated speed matching, including two methods.Method 1：Whether the emitter or receiver of cellular link are indicated using signaling explicitly or implicitly will do rate-matched.The position of rate-matched is determined in D2DSS subframes by the used resource of demodulated reference signal in the used resource of D2D links and cellular link.Method 2：For the receiver of cellular link, especially downlink receiver (this has such case when TDD descending sub frames are used for D2D), the method realized based on UE can be used.A kind of method is detected and decoded respectively with the transmission without D2DSS by the transmission for having D2DSS including UE, sees that the corresponding decoding result of any hypothesis is correct.Demodulated reference signal of another method on the 2nd symbol in D2DSS subframes de-spread after energy measuring because not having demodulated reference signal on the 2nd time slot, after de-spreading, relatively low energy is certainly existed by the demodulated reference signal on first time slot.If this assumes to set up, illustrate that currently used is D2DSS subframes, it is necessary to do the rate-matched of receiving side.
In addition, by constraint at present to D2D system designs, for a UE, on a carrier wave, sending and receiving can not do full duplex.I.e. for D2D UE, transmitting D2D signals must be TDM with receiving D2D signals.Similarly, to and for a synchronisation source UE, when there is a situation where multi-hop transmission (such as under the covering scene of part), the PD2DSCH signals from other synchronisation sources should be received by having some D2D synchronisation source, and oneself is sent again as the PD2DSCH signals of next-hop synchronisation source.
A kind of mode is：Using different D2DSS subframes when making the different synchronisation sources send PD2DSCH, specifically, the first synchronization control channel and the second synchronization control channel can be included in synchronization control channel, first synchronization control channel has the loading of the first transmitting end equipment, and the second synchronization control channel is by the second transmitting end equipment Loading, first synchronization control channel and the second synchronization control channel can take different synchronizing signal subframes.
It is understood that the synchronization control channel that can also have more transmitting end equipments to send, takes different synchronizing signal subframes respectively.
As shown in figure 33, an example schematic of different synchronizing signal subframes is used during for different synchronisation source transmission synchronization control channels, the synchronization control channel that first transmitting end equipment UE1 is sent takes the first two synchronizing signal subframe, the synchronization control channel that second sending ending equipment UE2 is sent takes the 3rd and the 4th synchronizing signal subframe, and the synchronization control channel that the 3rd sending ending equipment UE3 is sent takes the 5th and the 6th synchronizing signal subframe.So synchronisation source UE1 is when PD2DSCH is sent, it is not necessary to receive the 2nd in these subframes, 3 UE PD2DSCH, but can the 2nd, 3 UE send and are received on the position of PD2DSCH subframes.So as to solve the problem of half-duplex is limited.
I.e. in PD2DSCH transmission cycle, the PD2DSCH that a synchronisation source UE is actually sent only uses some of subframes, and different synchronisation source UE uses the different subframes in whole cycle when sending PD2DSCH.Also, transmission can take multiple continuous or discrete subframes every time.
The position for the PD2DSCH that each synchronisation source is sent can be by signaling UE or UE according to some gain of parameter by base station.Which specific synchronisation source UE uses which D2DSS subframe, then can be associated by multiple D2DSS sub-frame divisions in the PD2DSCH cycles into several parts by some parameters.Such as, synchronisation source UE can be obtained according to synchronisation source ID.As shown in Figure 33, if it can at most send out 3 different PD2DSCH in the PD2DSCH cycles, then all or part of in different synchronisation source ID can be used to obtain.Any 2 bit therein in synchronisation source ID binary codings is such as taken to indicate；Or by the individual position of its Synchronization Source, the value mould 3 of ten or hundred or whole Synchronization Source is obtained.Here 3 refer to the maximum quantity that can be indicated in the PD2DSCH cycles.Another to indicate different synchronisation source UE using the step number that the method for the different subframes within the PD2DSCH cycles is synchronisation source, the PD2DSCH of such as synchronisation source of different hop counts is placed on the diverse location in the PD2DSCH cycles.That is the first transmitting end equipment is different from the synchronisation source hop count that the second transmitting end equipment is presently in.
Another way is：First synchronization control channel takes symbols different in same synchronizing signal subframe from the second synchronization control channel, and synchronisation sources different in other words uses the different OFDM symbols in same D2DSS subframes when sending PD2DSCH.
Used when sending PD2DSCH as shown in figure 34 for different synchronisation sources in same D2DSS subframes Different symbols an example schematic, first transmitting end equipment UE1 PD2DSCH can use the 0 of the 1st time slot, Isosorbide-5-Nitrae, the symbol of 5 this four positions；And second transmitting end equipment UE2 PD2DSCH is then using the 0 of the 2nd time slot, Isosorbide-5-Nitrae, the symbol of 5 this four positions.Which specific synchronisation source UE uses which partial symbols, and symbol can be divided into several parts, then associated by some parameters.Such as, synchronisation source UE can be obtained according to synchronisation source ID.
Certainly the symbol in D2DSS subframes and subframe can also be divided into multiple subsets simultaneously, the PD2DSCH from different synchronisation source UE is associated with the corresponding symbol in corresponding subframe.
Because the emitter transmitting D2DSS of synchronisation source, while synchronisation source also necessarily PD2DSCH emitter.And different synchronisation sources can be independent synchronisation source or the timing reference for receiving other synchronisation sources, D2DSS is then launched still further below.The hop count of the corresponding synchronisation source of independent synchronisation source is the first jump, using the first synchronisation source to be then the second jump with reference to the synchronisation source launched.There is an example schematic of different current sync source hop counts for different D2D synchronisation sources as shown in figure 35.
Current sync source hop count residing for different synchronisation sources can be indicated by D2DSS sequences, or be indicated by the signaling being carried in PD2DSCH.Meanwhile, the PD2DSCH launched from different synchronisation sources position is distinguished for the ease of D2D receivers, the emitter with different current sync sources hop count is to that there should be the position in different time domains.Such as, hop count can be set to 0 in place for 0 PD2DSCH, and hop count can have a deviation post 1 relative to position 0 for 1 PD2DSCH, and hop count can have a deviation post 2 relative to position 0 for 2 PD2DSCH.Therefore when D2D UE receiver is detecting PD2DSCH, D2DSS can be first passed through to determine the current hop count residing for detected D2DSS, then corresponding PD2DSCH position is determined by corresponding deviation post in time.So as to further reduce the detection time of PD2DSCH receivers.
