Embodiment
Realize that for solving the D2D resource is distributed and the problem of transfer of data in cellular network, the embodiment of the invention provides a kind of method that the D2D resource is distributed that realizes in cellular network, the flow process of the inventive method as shown in Figure 1, channel and signaling that Fig. 2 uses when being each step in the execution graph 1, concrete execution in step is as follows:
Step S11: the base station receives the data transfer request that first user equipment (User Equipment, UE) sends.
Before carrying out above-mentioned steps, built vertical device-to-device (Device to Device Communication, D2D) connection of communicating by letter between a UE and the 2nd UE.When needing the transmission of data between a UE and the 2nd UE, at first send data transfer request by the data transfer direction base station, the data transfer request that receive data transmission side in base station sends.In actual applications, both can be with a UE as transmission side data, the 2nd UE is the data receiver, certainly, and also can be with the 2nd UE as transmission side data, a UE is as the data receiver.In the following description with a UE as transmission side data, the 2nd UE describes for example as the data receiver.
Concrete, above-mentioned base station receives the data transfer request that a UE sends, specifically comprise: the base station receives a UE by the buffer status report control signal that Physical Uplink Shared Channel sends, and wherein, carries request of data information in the buffer status report control signal.
According to LTE (Long Term Evolution, Long Term Evolution) regulation of agreement, (eNodB) initiates buffer status report (Buffer Status Report to the one UE to the base station, BSR) control signal, this signaling can be gone physically and be sent in the shared channel (Physical Uplink Shared Channel, PUSCH).When not having ascending resource PUSCH to send the BSR control signal, the one UE at first sends dispatch request (Scheduling Request to the base station, SR) control signal, this signaling can be passed through Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) send, the base station is that a UE distributes a small amount of ascending resource after receiving the SR control signal, namely distributes a small amount of PUSCH to send the BSR control signal.
Step S12: be that transfer of data between a UE and the 2nd UE is distributed Radio Resource according to the data transfer request that receives.
In the LTE system, the base station divides timing usually to consider the channel quality of each Radio Link carrying out resource.
Concrete, above-mentioned base station is that transfer of data between a UE and the 2nd UE is distributed Radio Resource according to the data transfer request that receives, and comprising: base station monitoring receives a UE and the 2nd UE by the channel quality indication (CQI) information of channel between the two of Physical Uplink Control Channel transmission; Judge Radio Resource channel quality between a UE and the 2nd UE according to the channel quality indication (CQI) information that receives, and be a UE and the 2nd UE distributing radio resource according to the Radio Resource channel quality of judging.
Realize that in cellular network D2D carries out resource and divides timing, the base station can by a UE and the 2nd UE periodically or the channel quality indication (CQI) information (Channel Quality Indicator, CQI) that reports to the base station of aperiodicity know channel conditions between the two.Because a UE set up the D2D connection with the 2nd UE, thus a UE and the 2nd UE can be regularly to the base station report and the opposite end between the channel quality indication (CQI) information of channel.This CQI can send by PUCCH.Here a UE/ the 2nd UE possesses the ability that the uplink pilot signal (Sounding Reference Signal, SRS) of sending according to the 2nd UE/ the one UE is carried out channel estimating.LTE of the prior art base station possesses this ability, and the LTE subscriber equipment does not possess this ability.
Step S13: the allocation of radio resources result is sent to a UE and/or the 2nd UE.
Concrete, above-mentioned the allocation of radio resources result is sent to a UE and/or the 2nd UE, following several mode can be arranged:
The first: the base station is by Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) the first allocation of radio resources signaling that will carry a UE identification information sends to a UE, and the second allocation of radio resources signaling that will carry the 2nd UE identification information sends to the 2nd UE.
Because in the LTE system, the base station is when sending signaling to subscriber equipment, the Radio Network Temporary Identifier (C-RNTI) of this subscriber equipment is carried in the capital, so the signaling that subscriber equipment can blind Detecting in the various signalings that the base station that receives sends carries the C-RNTI of oneself.
The first allocation of radio resources signaling that the C-RNTI of a UE will be carried in the base station sends to respectively a UE and the 2nd UE with the second allocation of radio resources signaling of carrying the C-RNTI of the 2nd UE, then, the signaling that the one UE and the 2nd UE only need blind Detecting to carry the C-RNTI of self gets final product, wherein, C-RNTI is as identification information.The method does not increase the number of times of UE blind Detecting.
The second: the base station sends to a UE by the 3rd allocation of radio resources signaling that Physical Downlink Control Channel will carry a UE identification information and wireless resource scheduling sign.
The C-RNTI of a UE will be carried in the base station and the 3rd allocation of radio resources signaling of Downlink Control Information (Downlink Control Information, DCI) form sends to a UE, and wherein, the DCI form identifies as wireless resource scheduling.Then a UE and the 2nd UE simultaneously blind Detecting carry the 3rd allocation of radio resources signaling of C-RNTI and the DCI form of a UE, namely can obtain the Radio Resource of base station assigns.
The signaling that contains a UE identification information that can the blind Detecting base station sends of the 2nd UE here, the 2nd UE obtains a UE identification information setting up with a UE when D2D is connected.Mistake may appear in this case, because the base station can send to a lot of signaling of a UE, what the 2nd UE might send to the base station the one UE is not to regard the allocation of radio resources signaling for the signaling of Resources allocation, for example, the BSR control signal of the request scheduling resource of UE transmission is replied in the base station in step S11, in order to send the BSR control signal for a UE Resources allocation, rather than in order to be used for to the 2nd UE the transmission of data for a UE.For fear of the generation of above-mentioned mistake, can utilize Flag forformat0/format1A differentiation field identification in the DCI form to identify signaling that the base station sends and whether come for the 2nd UE the transmission of data for D2D connection distributing radio resource.
The third: the base station sends to the 2nd UE by the 4th allocation of radio resources signaling that Physical Downlink Control Channel will carry the 2nd UE identification information and wireless resource scheduling sign.
The C-RNTI of the 2nd UE will be carried in the base station and the 4th allocation of radio resources signaling of Downlink Control Information (Downlink Control Information, DCI) form sends to the 2nd UE, and wherein the DCI form identifies as wireless resource scheduling.Then a UE and the 2nd UE simultaneously blind Detecting carry the 4th allocation of radio resources signaling of C-RNTI and the DCI form of the 2nd UE, namely can obtain the Radio Resource of base station assigns.
The signaling that contains the 2nd UE identification information that can the blind Detecting base station sends of a UE here, a UE obtains the 2nd UE identification information setting up with the 2nd UE when D2D is connected.The reason of carrying the wireless resource scheduling sign in the 4th allocation of radio resources signaling is the same with the second situation, repeats no more.
Above-mentioned dual mode can not increase signaling consumption, but needs to increase the blind Detecting number of times of UE.In actual conditions, UE only need to detect DCI Format corresponding in the signaling, and therefore, the blind Detecting number of times that UE need to increase can't be very large.
Channel and the signaling used in the first kind of way only are shown among Fig. 2, and the channel that uses in the second way and the third mode and the situation of signaling are not shown.
More excellent, after the above-mentioned steps S13, also comprise:
Step S14: the base station receives the 2nd UE and receives a UE and use the data receiver result who returns after the data of radio resource transfer of base station assigns, according to the data receiver result who receives determine whether be between a UE and the 2nd UE again the transmission of data keep the Radio Resource of distribution.
When the 2nd UE when receiving the data of UE transmission, might receive successfully, also might take defeat, therefore the 2nd UE need to be to base station return data reception result.
Concrete, above-mentioned base station receives the 2nd UE and receives a UE and use the data receiver result who returns after the data of radio resource transfer of base station assigns, and specifically comprise: the base station receives the data receiver feedback signaling that carries successfully ACK/ failure nack message that the 2nd UE sends by the time-frequency of setting in the Physical Uplink Control Channel; Perhaps the base station receives the data receiver feedback signaling that carries successfully ACK/ failure nack message that the 2nd UE sends by the guard band between Frequency Division Duplexing (FDD) in the Physical Uplink Control Channel and the time division duplex.
The 2nd UE can carry ACK/NACK information in sending to the data receiver feedback signaling of base station, when carry in the data receiver feedback signaling be NACK the time, the base station can between the first UE and the 2nd UE again the transmission of data keep the previous Radio Resource that distributes; When carry in the data receiver feedback signaling be ACK the time, the previous Radio Resource that distributes just need not have been reserved for their in the base station.
The embodiment of the invention provides a kind of method that realizes the D2D transfer of data in cellular network, flow process as shown in Figure 3, channel and the signaling used when Figure 2 shows that each step in the execution graph 3, execution in step is as follows:
Step S21: a UE sends data transfer request to the base station.
Before carrying out above-mentioned steps, built vertical D2D is connected between a UE and the 2nd UE.
Concrete, an above-mentioned UE sends data transfer request to the base station, specifically comprises: a UE sends the buffer status report control signal by Physical Uplink Shared Channel to the base station.
According to the regulation of LTE agreement, a UE initiates the BSR control signal to the base station, and this signaling can send in PUSCH.When not having ascending resource PUSCH to send the BSR control signal, the one UE at first sends the SR control signal to the base station, this signaling can send by PUCCH, and the base station is after receiving the SR control signal, be that a UE distributes a small amount of ascending resource, namely distribute a small amount of PUSCH to send the BSR control signal.
Step S22: a UE and the 2nd UE receive the allocation of radio resources result that the base station is returned, and wherein, the data transfer request that the base station basis receives is that the transfer of data between a UE and the 2nd UE is distributed Radio Resource.
Concrete, an above-mentioned UE and the 2nd UE receive the allocation of radio resources result that the base station is returned, and for three kinds of send modes of base station among the step S13, a UE and the 2nd UE receive also three kinds of modes, specifically comprises:
The first: a UE blind Detecting is carried the first allocation of radio resources signaling of self identification information, and the 2nd UE blind Detecting carries the second allocation of radio resources signaling of self identification information.
The signaling that the one UE and the 2nd UE only need blind Detecting to have self C-RNTI gets final product.The method does not increase the number of times of UE blind Detecting, can the increase signaling consumption but compare with traditional LTE Resource Allocation in Networks mode.
The second: a UE blind Detecting is carried the 4th allocation of radio resources signaling of the 2nd UE identification information and wireless resource scheduling sign; Wherein, a UE obtains the opposite end identification information with the 2nd UE when setting up the D2D connection.
The one UE and the 2nd UE simultaneously blind Detecting carry the 4th allocation of radio resources signaling of C-RNTI and the DCI form of the 2nd UE, both can obtain the Radio Resource of base station assigns.
The third: the 2nd UE blind Detecting is carried the 3rd allocation of radio resources signaling of a UE identification information and wireless resource scheduling sign.
The one UE and the 2nd UE simultaneously blind Detecting carry the 3rd allocation of radio resources signaling of C-RNTI and the DCI form of a UE, both can obtain the Radio Resource of base station assigns.
Step S23: a UE uses the Radio Resource of base station assigns to the 2nd UE the transmission of data, and the 2nd UE uses the Radio Resource of base station assigns to receive the data of UE transmission.
Concrete, an above-mentioned UE uses the Radio Resource of base station assigns to the 2nd UE the transmission of data, the 2nd UE uses the Radio Resource of base station assigns to receive the data of UE transmission, specifically comprise: a UE by Physical Uplink Shared Channel according to the Radio Resource of base station assigns to the 2nd UE the transmission of data, the 2nd UE receives the data of UE transmission according to the Radio Resource of base station assigns by Physical Uplink Shared Channel.
Because in D2D, a UE and the 2nd UE do not have the difference of up-downgoing when carrying out transfer of data.Adopt PUSCH here and do not adopt Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) to carry out transfer of data, main consideration reduces subscriber equipment implementation complexity and protocol modification degree as far as possible.Because subscriber equipment can't send the down public guide frequency signal, otherwise can interfere with each other with the Common Pilot Channel of base station, therefore select to adopt PUSCH to carry out transfer of data.
Here the 2nd UE has the ability of demodulation uplink pilot signal and data, and the base station in the LTE system of prior art possesses this ability, and subscriber equipment does not possess this ability.
Concrete, after the above-mentioned steps S23, also comprise:
Step S24: the 2nd UE is to a UE and base station return data reception result.
When the 2nd UE receives the data of UE transmission, might receive successfully, also might take defeat, therefore the 2nd UE need to be to a UE and base station return data reception result.In existing LTE system, the signaling of upstream data being carried out the ACK/NACK feedback sends by physical mixed ARQ indicating channel (Physical Hybrid ARQ Indicator Channel, PHICH).Consider that PHICH can't be well multiplexing with PUSCH, therefore adopt PUCCH to send.The ACK/NACK feedback that PUCCH can the bearing downlink data in the LTE system, but its time-frequency position is relevant with the time-frequency position of carrying out the PDCCH that the resource distribution indicates for downlink data.On the other hand, to distribute the PDCCH of indication be that previous or a plurality of subframes in actual data transfer are sent by the base station for the D2D transfer of data is carried out resource, therefore may carry PUCCH that D2D connects ACK/NACK information and clash the phase mutual interference with the time-frequency position of the PUCCH that carries the ACK/NACK information that normal cellular is connected.
In order to solve the above problems, the concrete following dual mode that can adopt solves:
The first, the 2nd UE sends the data receiver feedback signaling that carries successfully ACK/ failure nack message by the time-frequency of setting in the Physical Uplink Control Channel to the base station.
Here, the base station can specially for D2D reserves the time-frequency position that the transmission of data receives feedback signaling, when the 2nd UE need to carry the data receiver feedback signaling of ACK/NACK information to a UE and base station transmission, directly send by the time-frequency position of reserving to get final product.
The second, the 2nd UE send the data receiver feedback signaling that carries successfully ACK/ failure nack message to the base station by the guard band between Frequency Division Duplexing (FDD) in the Physical Uplink Control Channel and the time division duplex.
Utilize the carrier aggregation technology in the LTE-A system, transmit the data of D2D at expansion carrier wave (Extension Carrier), and transmit the data of normal cellular network at other carrier waves.The collision problem that PUCCH between D2D connection and the normal cellular network connection like this, just can not occur.It is as shown in Figure 4, a kind of that to adopt the scene of the method be to utilize the guard band between time division duplex (Time Division Duplex, TDD) and the Frequency Division Duplexing (FDD) (Frequency Division Duplex, FDD) to carry out the D2D transfer of data.Owing to only have PDCCH to use downlink resource in the process of realization D2D resource distribution and transfer of data among the present invention, and PDCCH transmits in the carrier aggregation system, does not transmit at the expansion carrier wave at general T DD carrier wave.Therefore, only take ascending resource in expansion carrier wave carrying D2D connection.Utilize protection bandwidth between TDD and the FDD upstream frequency as the expansion carrier wave of transmission D2D connection data, can take full advantage of this idling-resource, and can not produce TDD and the common carrier wave of FDD and disturb.
More excellent, after the above-mentioned steps S24, also comprise:
Step S25: a UE determines whether again to the 2nd UE equipment transmission data according to the data receiver result who receives.
Concrete, an above-mentioned UE determines whether again that according to the data receiver result who receives to the 2nd UE equipment transmission data, comprising: a UE receives the data receiver feedback signaling that carries successfully ACK/ failure nack message that the 2nd UE sends by the time-frequency of setting among the PUCCH; Perhaps receive the data receiver feedback signaling that carries successfully ACK/ failure nack message that the 2nd UE sends by the guard band between Frequency Division Duplexing (FDD) among the PUCCH and the time division duplex.
The 2nd UE can carry ACK/NACK information in sending to the data receiver feedback signaling of base station, when carry in the data receiver feedback signaling be NACK the time, the one UE can use the base station be between a UE and the 2nd UE again the transmission of data keep the previous Radio Resource that distributes, to the 2nd UE the transmission of data; When carry in the data receiver feedback signaling be ACK the time, a UE need not use the base station be between a UE and the 2nd UE again the transmission of data keep the previous Radio Resource that distributes, to the 2nd UE the transmission of data.
The below illustrates the above-mentioned detailed process that realizes the distribution of D2D resource and transfer of data in cellular network with a specific embodiment, and as shown in Figure 5, execution in step is as follows:
Step S31: a UE sends the SR control signal by PUCCH to the base station.
After the one UE and the 2nd UE have set up D2D and have been connected, the one UE is as transmission side data, and the 2nd UE is as the data receiver, and a UE will be to the 2nd UE the transmission of data, and the base station is not when having ascending resource to supply with a UE to send signaling, and a UE at first sends the SR control signal to the base station.
Step S32: after the base station receives the SR control signal, be that a UE distributes PUSCH to send the BSR control signal.
Step S33: a UE sends the BSR control signal by the PUSCH of base station assigns.
Step S34: after the base station received the BSR control signal that a UE sends, the CQI of channel was the transfer of data distribution Radio Resource between a UE and the 2nd UE between the two that sends by PUCCH according to a UE and the 2nd UE.
After having set up the D2D connection between a UE and the 2nd UE, a UE and the 2nd UE can periodicity or the acyclic CQI that sends channel between the two to the base station.
Step S35: the base station will carry the C-RNTI of a UE by PDCCH and the 3rd allocation of radio resources signaling of DCI form sends to a UE.
The second situation in three kinds of situations here only mentioning in the above-mentioned steps S13 describes as example.
Step S36: a UE and the 2nd UE blind Detecting contain the 3rd allocation of radio resources signaling of oneself C-RNTI and DCI form.
Step S37: a UE uses the Radio Resource of base station assigns to the 2nd UE the transmission of data, and the 2nd UE uses the Radio Resource of base station assigns to receive the data of UE transmission.
Step S38: the 2nd UE is that the data receiver feedback signaling of ACK/NACK information is carried to base station and UE transmission in the time-frequency position of the special PUCCH that reserves of D2D by the base station, what send as the 2nd UE is when carrying the data receiver feedback signaling of NACK, execution in step S39; What send as the 2nd UE is when carrying the data receiver feedback signaling of ACK, execution in step S40.
Step S39: the base station is the Radio Resource that distributes before the transmission of data keeps again between a UE and the 2nd UE.
