Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the present invention, and not It is whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making wound The every other embodiment obtained on the premise of working by the property made, should all belong to the scope of protection of the invention.

Technical scheme, can apply to various wireless communication systems, for example：Wideband code division is more Location (WCDMA, Wideband Code Division Multiple Access Wireless), high-speed packet Access (High-Speed Packet Access, HSPA), based on Wireless Fidelity (Wireless Fidelity, WIFI), bluetooth (Bluetooth), and worldwide interoperability for microwave accesses (Worldwide Interoperability For Microwave Access, WiMAX), WLAN authentication and privacy infrastructure (Wireless LAN Authentication and Privacy Infrastructure, WAPI), Long Term Evolution (LTE, long Term evolution) network, future network, such as 5G etc. systems and other by terminal with wireless parties The communication system that formula is interconnected.

Base station in the embodiment of the present invention, is the access entity in wireless communication system, can be GSM Or in the base station (BTS, Base Transceiver Station) in CDMA, or WCDMA Base station (NodeB), can also be evolved base station (eNB or e-NodeB, the evolved in LTE Node B), the base station in future network 5G, the present invention do not limit, but for convenience of description, it is following Embodiment is mainly illustrated by taking eNB as an example.

It should also be understood that in the embodiment of the present application, UE can be but not limited to mobile station (Mobile Station, abbreviation MS), mobile terminal (Mobile Terminal), mobile phone (Mobile Telephone), mobile phone (handset) and portable equipment (portable equipment) etc., the user Equipment can be with Jing wireless access networks (RAN, Radio Access Network) and one or more core nets Communicated, for example, computer etc., user equipment can also be portable, pocket, hand-held, Built-in computer or vehicle-mounted mobile device.

Fig. 1 is the indicative flowchart of the method 100 of distribution time-domain resource according to embodiments of the present invention. Method 100 is applied in device-to-device D2D communications, is used including m on a D2D communication link Family equipment UE, m are the integer more than or equal to 2.As shown in figure 1, method 100 is included in following Hold.

110th, base station obtains the offset information of Modulation, and offset information includes sending the control of D2D links Information SCI take time-domain resource and send data take time-domain resource between the first amount of bias, with And the second amount of bias between the time-domain resource that adjacent SCI or data take is sent, the second amount of bias is big In the first amount of bias, Modulation includes n kind emission modes, the every kind of transmitting mould in n kind emission modes Formula is used for the time-domain resource for indicating to send that SCI and data are taken respectively, and n is the integer more than 1.

It is understood that data here include D2D data.

Base station can adopt various methods to obtain the offset information of Modulation.For example, base station can basis Business demand, the communication environment of current area and the predetermined strategy that D2D communicates determines the inclined of Modulation Confidence ceases.Or, the offset information of various Modulations that can prestore in a base station, when needing for D2D During the user equipment allocation time-domain resource of communication link, communication of the base station according to business demand and current area Environment therefrom selects a kind of offset information of Modulation.

For another example, can in a base station a kind of pre-configured Modulation offset information (i.e. the first amount of bias and Second amount of bias), when the user equipment allocation time-domain resource for D2D communication links is needed, base station can So that the pre-configured offset information is obtained from memorizer.Equally, it is also possible in UE it is pre-configured this when The offset information of domain model.The Modulation can be defined by standard, or by network management Member's definition.Now as Modulation offset information has been pre-configured to be in UE sides, therefore base station can be with The offset information of Modulation is not sent to UE.

120th, base station determines the corresponding emission modes of a UE in m UE, corresponding an of UE Emission mode is the one kind in n kind emission modes.

130th, base station sends the first emission mode configured information to a UE, and the first emission mode is indicated Information is used to indicate the corresponding emission modes of a UE.

The method of the distribution time-domain resource of the embodiment of the present invention, it is true by the offset information for obtaining Modulation The fixed Modulation for adopting, and send for indicating to send out to a user equipment on D2D communication links The emission mode configured information of emission mode, can be each user equipment point on multi-hop D2D communication links With time-domain resource.

For example, emission mode configured information can include the mark of emission mode, and UE can be according to transmitting The mark of pattern determines corresponding emission mode from n kind emission modes.Wherein, the mark of emission mode Can be numbering or code of emission mode etc..

Alternatively, a UE is the source UE on D2D communication links.Wherein, source UE refers to D2D The first jump UE (the first sender for jumping) on communication link.

Example, in the embodiment of the present invention, by the way of the instruction of emission mode can be to be indicated using chain type. Under this mode, base station only sends emission mode configured information to the source UE on D2D communication links.Source UE can determine next-hop after determining corresponding emission mode according to the emission mode configured information for receiving The corresponding emission modes of UE, and the next-hop UE emission mode is notified, by that analogy, D2D communications Often jump UE on link determines the corresponding emission mode of next-hop UE, and notifies down hop UE.Show Example, each UE that jumps determines the corresponding emission mode of next-hop UE, can be carried out according to default rule It is determined that, such as, the emission mode index number of next-hop UE is：(the emission mode index of current UE Numbering+1) mod editor-in-chief's count.The corresponding emission modes of UE of the adjacent hop on D2D communication links It is different.

Alternatively, the instruction of emission mode can be with by the way of star-like instruction.Under this mode, side Method 100 can also include：

Base station determines each the 2nd UE at least one the 2nd UE in m UE outside a UE Corresponding emission mode, each corresponding emission mode of the 2nd UE are the one kind in n kind emission modes；

Base station sends the second emission mode configured information to each the 2nd UE at least one the 2nd UE, Second sending mode configured information is used to indicate the corresponding emission modes of the 2nd UE.

That is, in the embodiment of the present invention, UE sends transmitting mould to each UE in m UE Formula configured information, to notify the corresponding emission modes of each UE.

Example, the corresponding emission modes of UE of the adjacent hop on D2D communication links are different.

Alternatively, the instruction of emission mode can also adopt what star-like instruction above and chain type instruction combined Mode, will not be described here.

It should be noted that the corresponding emission modes of each UE on a D2D communication link can not be sent out Raw conflict, or the time-domain resource that the corresponding emission modes of the adjacent UE on a D2D link take is not Can clash.For example, upper hop UE in the double bounce UE of arbitrary neighborhood send that data take when Domain resource and next-hop UE send at least interval data between the time-domain resource that SCI and/or feedback take and exist The handling duration needed during transmission and reception.

Alternatively, step 110 includes：Base station determines the offset information of Modulation.

If the offset information of Modulation is determined by base station, base station needs to inform what UE was adopted Modulation.

Correspondingly, method 100 also includes：Base station sends the first amount of bias and the second biasing to m UE Amount.UE can determine the Modulation of employing according to the first amount of bias and the second amount of bias.

The embodiment of the present invention is not construed as limiting to the method that base station sends the first amount of bias and the second amount of bias.The One for example, and base station can send first amount of bias and second amount of bias to m UE by broadcast, or Base station can also send first amount of bias and second biasing to m UE by radio resource control signaling Amount.

In the embodiment of the present invention, base station is by sending the first amount of bias and the second amount of bias to UE so that UE can determine the Modulation of employing.

It should be understood that the emission mode of the UE in front and back on D2D links has stronger coupled relation. Under a certain Modulation, after the emission mode of previous dive UE determines, the emission mode of latter jump UE Correspondingly can decide naturally.

Alternatively, every kind of emission mode is additionally operable to indicate the time-domain resource that send feedback information takes.

For example, feedback information can be confirmation (Acknowledgement, abbreviation ACK), negativity Confirm (Negative ACKnowledgement, abbreviation NACK), channel condition information (Channel State Information, abbreviation CSI) etc., the embodiment of the present invention is not limited to this.Wherein, feed back Information can be used to determine whether to retransmit, and then improve the reliability of data transfer.

Middle UE on multi-hop D2D communication links can be with upper hop UE send feedback information.Should Understand, UE send feedback informations can share time-domain resource with SCI is sent.For example, a UE can With simultaneously to two UE difference send feedback informations and SCI.

For example, upper hop UE in the double bounce UE of arbitrary neighborhood send time-domain resource that data take with Between the time-domain resource that next-hop UE send feedback information takes, at least interval data is being transmitted and was being received The handling duration needed in journey.So ensure that next-hop UE has time enough processing data bag.

Alternatively, the time domain that the next-hop UE send feedback information in the double bounce UE of arbitrary neighborhood takes Resource and upper hop UE send again The handling duration needed during defeated and reception.

So ensure that upper hop UE had before new SCI and data are sent time enough according to The feedback information of next-hop UE performs corresponding operation.For example, upper hop UE is true according to feedback information It is fixed whether to need down hop UE to resend data, or upper hop UE is carried out according to feedback information Resource allocation of data transfer etc..

It should be understood that D2D communications can be using FDD (Frequency Division Duplex, letter Claim FDD), it would however also be possible to employ time division duplex (Time Division Duplex, abbreviation TDD).FDD Under pattern, the available subframe of D2D communications is all of subframe under upstream band, and under tdd mode, D2D leads to The available subframe of letter is sub-frame of uplink.It should also be understood that in tdd mode, two adjacent up sons Between frame may be spaced several descending sub frames, descending sub frame not the embodiment of the present invention consider scope it It is interior.The subframe of the embodiment of the present invention refers to the available subframe of D2D communications.

Alternatively, when D2D communications are using FDD, the first amount of bias is 1 subframe.Second biasing Measure as 9 subframes.

It should be understood that the first amount of bias can also be the subframe of other quantity, such as 2 subframes, or 3 Subframe.It should also be understood that the first amount of bias is less, then in D2D communications during the transmission end to end of data Prolong less, efficiency of transmission is higher.Second amount of bias can also be the subframe of other quantity, and such as 8 sub Frame, or 10 subframes, or 11 subframes.

Alternatively, when D2D communications are using TDD, the first amount of bias is 1 sub-frame of uplink.Second Amount of bias is 5 sub-frame of uplink.It should be understood that the first amount of bias can also be the sub-frame of uplink of other quantity, Such as 2 sub-frame of uplink, or 3 sub-frame of uplink.Similarly, the first amount of bias is less, then D2D In communication, the propagation delay time end to end of data is less, and efficiency of transmission is higher.Second amount of bias can also be The sub-frame of uplink of other quantity, such as 6 sub-frame of uplink, or 7 sub-frame of uplink.

Fig. 2 is the indicative flowchart of the method 200 of distribution time-domain resource according to embodiments of the present invention. Method 200 is corresponding with method 100, succinct in order to describe, and here suitably omits corresponding description, is saved Description in method 100 is partly referred to slightly.Method 200 is applied to multi-hop device-to-device D2D and leads to In letter, on a D2D communication link, include m user equipment (UE), method 200 is by m UE In arbitrary UE perform, m is the integer more than or equal to 2.As shown in Fig. 2 method 200 includes Following content.

210th, UE obtains the first amount of bias and the second amount of bias, and the first amount of bias is to send what SCI took Amount of bias between the time-domain resource that time-domain resource and transmission data take, the second amount of bias are adjacent to send SCI or data take two time-domain resources between amount of bias, the second amount of bias more than first bias Amount.
