Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

In existing a solution, base station individually indicates that launch terminal sends scheduling point by a plurality of signaling Match or data, available bit number is more, and efficiency does not protrude.In existing another solution, base station passes through one Signaling, the signaling can be Downlink Control Information (Downlink Control Information, DCI), such as DCI0 can be with Support to indicate two pieces of frequency domain resources simultaneously, but since this two pieces of resources generation is in a time quantum, thus between have phase Guan Xing will remove the case where two pieces of resources are linked to be one piece and overlapping.

In the embodiment of the present invention, base station needs the money by signaling instruction terminal transmission simultaneously dispatching distribution and data Source sends dispatching distribution and data by the bit field of Downlink Control Information or high-level signaling instruction terminal, but this two pieces Data are due to the transmission that is staggered on the time, so the resource occupied is completely independent, so the frequency domain that SA and data occupy respectively Resource can be partly or entirely overlapped.The bit number of SA compares less, and the frequency domain resource quantity of occupancy can fix；And data The stock number of distribution is variable.

If the adaptive-bandwidth of data resource, common method is using embedded scheme.Such as: the bandwidth of data is base The integral multiple of this granularity can use embedded (nested) scheme, that is, dispatch when scheduling bandwidth is greater than basic granularity When band is wider than basic granularity, the frequency domain resource of multiple basic granularities can be regarded while dispatched as, and existing single carrier is special Property to need the entire scheduling bandwidth of a terminal device be continuous, that is, use embedded scheme, need multiple basic grains What the frequency domain resource of degree was connected with, when the time is upper repeatedly to be sent, it is desirable that once it is adjacent a moment, it needs in others Moment is also adjacent, and relative positional relationship is constant.And the problem of D2D distinctive band internal leakage: if pattern (pattern) A It is at a time adjacent with the frequency resource of pattern B, consider the problems of band internal leakage, needs or preferably subsequent time is not It is adjacent, play the role of interference randomization.By the above two o'clock it can be concluded that, the frequency domain resource that embedded scheme communicates D2D Distribution there are conflicting demand, can not detail of design, or greatly increase the complexity of configurations.

Referring to Fig. 2, being a kind of flow chart of resource allocation method provided in an embodiment of the present invention.This method includes following Step:

Step S101, base station send the first scheduling information to user equipment (UE), and first scheduling information is used to indicate institute State the initial position of the dispatching distribution SA band occupancy of UE；First scheduling information is also used to indicate that the data of the UE occupy The initial position of frequency band；

When UE carries out D2D communication, the operating mode of UE is configurable, for example, UE can work in the mode one or mould of D2D Formula two.In the present embodiment, in the mode one of D2D, i.e. eNB or relay node scheduling UE are used for transmission directly for base station configuration UE work The resource for connecting the data and control information of letter, the scene covered applied to the network coverage or subnetwork.

In the present embodiment, the width SA corresponding with other UE in base station range that SA band occupancy is arranged occupies frequency The width of band is equal；The width of the width of data band occupancy data band occupancy corresponding with other UE in base station range Spend it is equal, in this way, the initial position for the frequency band that the scheduling information that base station is sent to UE only needs to indicate that SA and data are occupied respectively , base station can also explicitly indicate that UE sends dispatching distribution and data by less bit number, save the signaling of base station Expense.The scheduling information of base station can be Downlink Control Information or high-level signaling.Since UE transmission dispatching distribution and data do not exist Occur simultaneously on time, the frequency band that SA and data occupy respectively can be partly or entirely overlapped.

As it can be seen that a kind of resource allocation method provided according to embodiments of the present invention, by making dispatching distribution band occupancy The width of width dispatching distribution band occupancy corresponding with other user equipmenies in base station range it is equal, and make The width of the width of data band occupancy data band occupancy corresponding with other user equipmenies in base station range is equal, The scheduling information of base station need to only indicate the dispatching distribution of user equipment and the initial position of data difference band occupancy, can define And efficiently scheduling user's set sends dispatching distribution and data, saves the signaling overheads of base station.

Referring to Fig. 3, for the flow chart of another resource allocation method provided in an embodiment of the present invention.This method include with Lower step:

Step S201, base station send the first scheduling information to user equipment (UE), and first scheduling information is used to indicate institute State the initial position of the dispatching distribution SA band occupancy of UE；First scheduling information is also used to indicate that the data of the UE occupy The initial position of frequency band；

Step S201 is identical as the step S101 of previous embodiment, and details are not described herein.

Step S202, the base station send pattern instruction message to the UE, and the pattern instruction message is used to indicate institute It states UE and transmits the pattern used when the SA or data, the pattern includes the information of the number of retransmissions of the SA or data；

In the present embodiment, when frequency resource quantity is identical, the size of transmission block (Tranport Block, TB) but may Difference may cause if the number of transmissions in time domain is identical and carry out received UE when receiving different size of TB data Receptivity is different；In addition, when terminal carries out the transmitting of D2D data, if carrying out transmission power control, the hair of the UE emitted Penetrating power can change over time, it is possible to even if the UE for allowing to carry out transmitting sends equally long transmission block, carry out received Receptivity of the UE when receiving transmission block is also different.Therefore, in order to enable carrying out the UE that received UE is emitted when reception There is comparable receptivity when the transport block size difference of transmitting and/or when the UE emitted does transmission power control, It can increase that length is longer and/or the number of retransmissions of the lesser transmission block of transmission power, adjust final code rate, therefore, base station root The number of retransmissions of data is determined according to parameter preset.

The parameter preset may include: the number of retransmissions mapping of signal-to-noise ratio, the bit number of the transmission block or the data Any one of table or any combination.

The pattern that base station uses when can be by sending pattern instruction message, instruction UE transmission SA or data to UE, the figure Sample includes the information of the number of retransmissions of SA or data, wherein number of retransmissions is the time resource unit for transmitting SA or data occupancy Quantity, specifically, pattern instruction message can serve to indicate that the serial number of pattern.The resource distribution mode that base station is indicated to UE can be with It is pattern, which is that the two-dimentional resource sequence of finite length comprising one or more time-frequency domains and/or frequency domain have limit for length The one dimensional resource sequence of the finite length of the one dimensional resource sequence and/or time domain of degree, the pattern that instruction UE is used when base station, into The UEUE of row transmitting is according to the two-dimentional resource sequence of the finite length of time-frequency domain or the one dimensional resource sequence of the finite length of frequency domain Or the length of the one dimensional resource sequence of the finite length of time domain can determine the number of retransmissions of SA or data, base station is no longer needed to by aobvious The UEUE that the field signals shown are emitted, i.e. base station are implicitly notified of the number of retransmissions of the UEUE data emitted.

It is of course also possible to the number of retransmissions of SA or data directly be indicated in scheduling information, for example, passing through the field of display Indicate the number of retransmissions of SA or data.

As it can be seen that a kind of resource allocation method provided according to embodiments of the present invention, by making dispatching distribution band occupancy The width of width dispatching distribution band occupancy corresponding with other user equipmenies in base station range it is equal, and make The width of the width of data band occupancy data band occupancy corresponding with other user equipmenies in base station range is equal, The scheduling information of base station need to only indicate the dispatching distribution of user equipment and the initial position of data difference band occupancy, can define And efficiently scheduling user's set sends dispatching distribution and data, saves the signaling overheads of base station；And it is sent out by instruction The UE user equipment penetrated sends the number of retransmissions of dispatching distribution or data, and D2D can be made, which to carry out received user equipment, to be connect When receiving the transport block size difference of the user equipment transmitting emitted and/or when the user equipment that be emitted is emitted When power control, there is comparable receptivity.

Referring to Fig. 4, being the flow chart of another resource allocation method provided in an embodiment of the present invention.This method include with Lower step:

Step S301, base station indicate the scheduling point of user equipment (UE) by the bit field or high-level signaling of Downlink Control Information Match and/or the resource distribution mode of data.

The resource distribution mode of base station instruction UE refers to that the currently employed resource distribution mode of instruction UE, a UE can divide When flexibly use different resource distribution modes, i.e. the different cycles in two periods in the period of SA or SA can be distinguished Using two periods in the period of the first resource method of salary distribution and the Secondary resource method of salary distribution or data or the difference week of data The first resource method of salary distribution and the Secondary resource method of salary distribution can be respectively adopted in phase.

The frequency domain granularity that the resource distribution mode can be SA and/or data occupy, refers to shared by the frequency domain of primary distribution RB quantity.Such as: in the resource pool of the first granularity resource method of salary distribution, UE carries out the frequency domain distributed when the direct-connected communication of terminal money Source is all 4RB, in the resource pool of the second granularity resource method of salary distribution, the frequency domain resource of distribution when UE carries out terminal direct-connected communication It is all 6RB.

The time domain granularity that the resource distribution mode can be SA and/or data occupy.Such as: the first granularity resource distribution side In the resource pool of formula, the time-domain resource that UE distribute when the direct-connected communication of terminal is all 4 time quantums (subframe), second In the resource pool of the granularity resource method of salary distribution, the time-domain resource of distribution when UE carries out terminal direct-connected communication is all 6 time lists First (subframe).

The resource distribution mode is also possible to the two-dimentional resource of time domain and frequency domain, such as: the first granularity resource method of salary distribution Resource pool in, UE carries out the time domain distributed when the direct-connected communication of UE and frequency domain resource is all (4RB, 4 subframe), second Spend in the resource pool of resource distribution mode, the time domain and frequency domain resource of distribution when UE carries out UE direct-connected communication be all (6RB, 6 subframe)。

As a specific implementation manner, which can be resource pattern, and system intialization has multiple moneys Source pattern, base station and UE know altogether.Each resource pattern is the one dimensional resource sequence of frequency domain, that is, may include multiple frequency domain resource lists First (Resource Block, RB)；The either one dimensional resource sequence of time domain, that is, may include multiple time domain time quantums；Or Each resource pattern is the two-dimentional resource sequence of one or more time-frequency domains, that is, may include multiple time domain time quantums and every Frequency resource element (Resource Block, RB) on a time quantum includes multiple frequency resource elements and each The corresponding time quantum of frequency resource element.By taking two-dimentional resource pattern as an example: being the sequence of a two-dimensional coordinate pair, (frequency domain Index, time domain index), such as: as shown in Figure 5 a, { (3,5), (2,7), (1,8), (4,9) } are that there are four videos for a tool The time-frequency two-dimensional pattern (pattern as shown in figure bend) of two-dimentional resource, this pattern can make UE uniquely find time-frequency two Each resource points (unit) of dimension are sent or are received data.Again by taking one-dimensional time-domain resource pattern as an example: being one one-dimensional The sequence of coordinate, (time domain index), such as: as shown in Figure 5 b, { (1), (3), (4), (6), (7), (8) }, which are one, has six The one-dimensional time domain pattern (as shown in the thick line in figure) of a time-domain resource unit (time quantum), this pattern can make UE unique The each resource points (unit) for finding time domain sent or received data.Another advice method can be (1), (0), (1) (1), (0), (1), (1), (1) } if 1 represent transmitting, 0 represent receive, UE can uniquely confirm oneself transmission and Receiving time unit.

In the present embodiment, base station can classify according to the frequency domain resource granularity that resource pool includes, and can be classified as One granularity resource pond and the second granularity resource pond etc.；It can also be classified according to the quantity for the time-domain resource that resource pool includes, It can be classified as the first granularity resource pond and the second granularity resource pond etc.；It can also be according to time domain, frequency domain, the one-dimensional money of time-frequency domain Source or two-dimentional resource are classified.Here " first " and " second " only indicates that the size of granularity or quantity are different, not Limitation is specifically divided into several classes.

It should be noted that not occurring simultaneously in time due to sending SA and data, so SA and data can be used Different resource distribution modes also can be used in same resource distribution mode.

Step S302, the base station send the first scheduling information to the UE, and first scheduling information is used to indicate institute State the time domain and/or frequency resource element that the SA of UE is occupied under corresponding resource distribution mode；And/or the first scheduling letter Breath is also used to indicate the time domain and/or frequency resource element that the data of the UE occupy under corresponding resource distribution mode.

Specifically, which includes start position information, and initial position message is used to indicate SA in corresponding resource The initial position of band occupancy under the method for salary distribution；Initial position message may be used to indicate that data in corresponding resource distribution mode The initial position of the frequency band of lower occupancy.Due to SA and the frequency bandwidth of data, that is, frequency domain resource granularity passed through it is corresponding Resource distribution mode instruction, therefore, base station only need the initial position of instruction SA or data difference band occupancy, and base station passes through less Bit number can also explicitly indicate that UE sends dispatching distribution and data, save the signaling overheads of base station.

Optionally, the present embodiment may also include step S303, with dotted line Connection Step S302 in figure.

Step S303, the base station indicate the number of the UE by the bit field or high-level signaling of the Downlink Control Information It is poor according to the time domain time quantum quantity relative to dispatching distribution.

Since the resource allocation of dispatching distribution and data is base station while being indicated, and there are many possible resources point for terminal With mode, therefore, base station also indicates time difference of the data relative to dispatching distribution, in this way, UE can according to dispatching distribution when Between unit number (index) determine the time quantums (number) of subsequent data, tune is sent using the frequency domain resource that base station indicates respectively Degree distribution and data.Such as: if dispatching distribution occurs in n-th of time quantum, and time domain time quantum quantity difference is 4, then counts According to generation in (n+4) a time quantum.

In the present embodiment, base station indicates the data of UE relative to tune by the bit field or high-level signaling of Downlink Control Information The time domain time quantum quantity for spending distribution is poor, for example, by indicating that information indicates that the time domain time quantum quantity is poor.

It optionally, can also the time domain time quantum quantity be poor by pattern implicit instruction.The pattern be comprising one or The two-dimentional resource sequence of the finite length of multiple time-frequency domains or the one dimensional resource sequence of frequency domain/time domain finite length, base station Without the field signals UE by display, need to only indicate the resource pattern used, UE according to the two-dimentional resource sequence of time-frequency domain or The length of the one dimensional resource sequence of time domain can determine the time quantum quantity of data, i.e. base station is implicitly notified of the UE emitted The time quantum quantity of data.

As it can be seen that a kind of resource allocation method provided according to embodiments of the present invention, base station is by configuring at least two resources The method of salary distribution allows UE flexibly using different resource distribution modes；From system perspective, so that different resource allocations Corresponding time domain, frequency domain resource can be allocated to different UE, more flexible distribution resource, and the signaling for saving base station is opened Pin, improves the efficiency of system.

Referring to Fig. 6, being the flow chart of another resource allocation method provided in an embodiment of the present invention.This method include with Lower step:

Step S401, base station send configuration information to user equipment (UE), and the configuration information is used to indicate at least two moneys The time-frequency location in source pond, wherein at least one first resource pond correspond to the first resource method of salary distribution, at least one Secondary resource pond The corresponding Secondary resource method of salary distribution.

In the present embodiment, resource allocation is carried out according to the configuration of resource pool.Firstly, base station needs to notify UE about resource pool Configuration information, that is, indicate the time-frequency location of each resource pool.Wherein, base station can notify in all base station service ranges UE。

The resource pool can be the resource pool or user's direct connection communication D2D mode of user's direct connection communication D2D mode one The resource pool of two resource pool, attention mode one and mode two orthogonal (not being overlapped) or can be partially or completely overlapped.

The frequency domain granularity that the resource distribution mode can be SA and/or data occupy, refers to shared by the frequency domain of primary distribution RB quantity.Such as: in the resource pool of the first granularity resource method of salary distribution, terminal carries out the frequency domain distributed when the direct-connected communication of terminal Resource is all 4RB, in the resource pool of the second granularity resource method of salary distribution, the frequency domain of distribution when terminal carries out terminal direct-connected communication Resource is all 6RB.

The time domain granularity that the resource distribution mode can be SA and/or data occupy.Such as: the first granularity resource distribution side In the resource pool of formula, the time-domain resource that terminal distribute when the direct-connected communication of terminal is all 4 time quantums (subframe), the In the resource pool of the two granularity resource methods of salary distribution, when the time-domain resource of distribution when terminal carries out terminal direct-connected communication is all 6 Between unit (subframe).

The resource distribution mode is also possible to the two-dimentional resource of time domain and frequency domain, such as: the first granularity resource method of salary distribution Resource pool in, terminal carries out the time domain distributed when the direct-connected communication of terminal and frequency domain resource is all (4RB, 4 subframe), the In the resource pool of the two granularity resource methods of salary distribution, the time domain and frequency domain resource of distribution when terminal carries out terminal direct-connected communication are all (6RB, 6 subframe).

As a specific implementation manner, which can be pattern, and system intialization has multiple patterns, base It stands and terminal is known altogether.Each pattern is the one dimensional resource sequence of frequency domain, that is, may include multiple frequency resource element (Resource Block, RB)；The either one dimensional resource sequence of time domain, that is, may include multiple time domain time quantums；Or each pattern is The two-dimentional resource sequence of one or more time-frequency domains may include the frequency on multiple time domain time quantums and each time quantum Domain resource unit (Resource Block, RB) is corresponding comprising multiple frequency resource elements and each frequency resource element Time quantum.By taking two-dimentional pattern as an example: it is the sequence of a two-dimensional coordinate pair, (frequency domain index, time domain index), such as: As shown in Figure 5 a, { (3,5), (2,7), (1,8), (4,9) } are that there are four the time-frequency two-dimensional patterns of video two dimension resource for a tool (pattern as shown in figure bend), the terminal that this pattern can make uniquely find each resource points (unit) of time-frequency two-dimensional Sent or received data.Again by taking one-dimensional time domain pattern as an example: being the sequence of an one-dimensional coordinate, (time domain index), example Such as: as shown in Figure 5 b, { (1), (3), (4), (6), (7), (8) } are that there are six time-domain resource unit (time quantums) for a tool One-dimensional time domain pattern (as shown in the thick line in figure), this pattern can make terminal uniquely find each resource points of time domain (unit) is sent or is received data.Another advice method can be (1), (0), (1) (1), (0), (1), (1), (1) } it represents and receives if 1 represents transmitting, 0, what terminal can uniquely confirm oneself sends and receives time quantum.

In the present embodiment, base station can classify according to the frequency domain resource granularity that resource pool includes, and can be classified as One granularity resource pond and the second granularity resource pond etc.；It can also be classified according to the quantity for the time-domain resource that resource pool includes, It can be classified as the first granularity resource pond and the second granularity resource pond etc.；It can also be according to time domain, frequency domain, the one-dimensional money of time-frequency domain Source or two-dimentional resource are classified.Here " first " and " second " only indicates that the size of granularity or quantity are different, not Limitation is specifically divided into several classes.Therefore, varigrained resource pool corresponds to a kind of resource distribution mode.

Step S402, the base station send resource pool instruction message to the UE, and the resource pool instruction message is for referring to Show and distributes at least one described first resource pond or at least one second money that the UE sends dispatching distribution SA and/or data Source pond.

After the configuration information of resource pool is sent to UE by base station, instruction is also needed to distribute to resource pool used in UE, according to The information such as the data package size of SA and data that UE to be sent distribute varigrained resource pool, that is, use different resources The method of salary distribution.It should be noted that not occurring simultaneously in time due to sending SA and data, so SA and data can be used Different resource distribution modes also can be used in same resource distribution mode.Specifically, base station can be by the first granularity resource Pond and the second granularity resource pond are respectively configured to some terminals, and some terminals are provided using the time domain in the first granularity resource pond, frequency domain Source is scheduled distribution and the transmission of data, other terminals then use the time domain in the second granularity resource pond, frequency domain resource to carry out The transmission of dispatching distribution and data.

Step S403, the base station send the first scheduling information to the UE, and first scheduling information is used to indicate institute State at least one described first resource pond or time domain and/or frequency domain money at least one Secondary resource pond that the SA of UE is occupied Source；And/or first scheduling information be also used to indicate the UE data occupy at least one described first resource pond or Time domain and/or frequency domain resource at least one Secondary resource pond.

Since the resource pool of a granularity contains multiple time domains and/or frequency resource element, multiple adopt can be distributed to It is used with the UE of same resource distribution mode, so base station also needs to send scheduling information to UE, some money that instruction SA is occupied The specific time domain and/or frequency resource element in source pond are also used to the specific time domain of some resource pool of designation date occupancy And/or frequency resource element.

Specifically, which includes start position information, and initial position message is used to indicate SA and occupies some granularity Resource pool in frequency band initial position；Initial position message may be used to indicate that the resource pool for some granularity that data occupy In frequency band initial position.The frequency bandwidth for sending SA or data using the UE of the resource pool of same granularity is equal, therefore, base The initial position for the frequency band stood in the resource pool of some granularity for only needing instruction SA or data to occupy respectively, base station passes through less Bit number can also explicitly indicate that UE sends dispatching distribution and data, save the signaling overheads of base station.

As it can be seen that a kind of resource allocation method provided according to embodiments of the present invention, base station is by configuring at least two times Upper nonoverlapping D2D communication resource pond allows terminal flexibly using different resource distribution modes；From system perspective, The time domain of different resource pools, frequency domain resource is allowed to be allocated to different terminals, more flexible distribution resource saves The signaling overheads of base station improves the efficiency of system.

Referring to Fig. 7, being a kind of flow chart of user's direct connection communication means provided in an embodiment of the present invention, this method includes Following steps:

Step S501, the first user equipment (UE) receive the first scheduling message that base station is sent, and first scheduling information is used In the initial position for the dispatching distribution SA band occupancy for indicating the UE；First scheduling information is also used to indicate the UE's The initial position of data band occupancy；Wherein, other UE in the width Yu the base station range of the SA band occupancy The width of corresponding SA band occupancy is equal；The width and other UE in the base station range of the data band occupancy The width of corresponding data band occupancy is equal.

When UE carries out D2D communication, the operating mode of UE is configurable, for example, UE can work in the mode one or mould of D2D Formula two.In the present embodiment, UE receives the configuration of base station, works in the mode one of D2D, i.e. eNB or relay node scheduling UE are used In the resource of the data and control information of transmission direct communication, the scene covered applied to the network coverage or subnetwork.

In the present embodiment, the width SA corresponding with other UE in base station range of base station setting SA band occupancy is accounted for It is equal with the width of frequency band；The width of data band occupancy data band occupancy corresponding with other UE in base station range Width it is equal, in this way, the starting for the frequency band that the scheduling information that base station is sent to UE only needs to indicate that SA and data are occupied respectively Position, base station can also explicitly indicate that UE sends dispatching distribution and data by less bit number, save base station Signaling overheads.The scheduling information of base station can be Downlink Control Information or high-level signaling.Since UE sends dispatching distribution and data Do not occur simultaneously in time, the frequency band that SA and data occupy respectively can be partly or entirely overlapped.UE receives the scheduling message.

Step S502, the first UE according to first scheduling information, the initial position of the SA band occupancy to 2nd UE sends the SA, and the initial position of the frequency band in data occupancy sends the data to the 2nd UE.

UE is according to the initial position, can be accurately to the progress of D2D communication on the frequency band that SA and data are occupied respectively Received UE sends SA and data.

As it can be seen that a kind of user's direct connection communication means provided according to embodiments of the present invention, the tune sent by receiving base station Information is spent, since the width of base station setting dispatching distribution band occupancy is corresponding with other user equipmenies in base station range The width of dispatching distribution band occupancy is equal and the width and base station range of data band occupancy in other users set The width of standby corresponding data band occupancy is equal, which need to only indicate the dispatching distribution and data difference of user equipment The initial position of band occupancy, can make that base station defines and efficiently scheduling user's set sends dispatching distribution and data, save The signaling overheads of base station, user equipment also can be according to the startings for the frequency band and respective band occupancy that SA and data occupy respectively Position accurately sends SA and data.

Referring to Fig. 8, for the flow chart of another user's direct connection communication means provided in an embodiment of the present invention, this method packet Include following steps:

Step S601, the first user equipment (UE) receive the first scheduling message that base station is sent, and first scheduling information is used In the initial position for the dispatching distribution SA band occupancy for indicating the UE；First scheduling information is also used to indicate the UE's The initial position of data band occupancy；Wherein, other UE in the width Yu the base station range of the SA band occupancy The width of corresponding SA band occupancy is equal；The width and other UE in the base station range of the data band occupancy The width of corresponding data band occupancy is equal.

Step S602, the first UE according to first scheduling information, the initial position of the SA band occupancy to 2nd UE sends the SA, and the initial position of the frequency band in data occupancy sends the data to the 2nd UE.

Step S601 and S602 are identical as the step S501 and S502 of previous embodiment respectively, and details are not described herein.

Step S603, the first UE according to first scheduling information SA indicated or the number of retransmissions of data, The SA or data are retransmitted to the 2nd UE, wherein the time money that the number of retransmissions is the transmission SA or data occupy Source unit quantity.

Step S603 is also possible to the first UE and receives the pattern instruction message that the base station is sent, the pattern instruction Message is used to indicate the first UE and transmits the pattern used when the SA or data, and the pattern includes the SA or data The information of number of retransmissions, wherein the time resource element number that the number of retransmissions is the transmission SA or data occupy.

Step S604, the first UE retransmit the SA or number according to the information of the number of retransmissions, the 2nd UE of Xiang Suoshu According to.

In the present embodiment, when frequency resource quantity is identical, the size of transmission block (Tranport Block, TB) but may Difference may cause if the number of transmissions in time domain is identical and carry out received UE when receiving different size of TB data Receptivity is different；In addition, when terminal carries out the transmitting of D2D data, if carrying out transmission power control, the hair of the UE emitted Penetrating power can change over time, it is possible to even if the UE for allowing to carry out transmitting sends equally long transmission block, carry out received Receptivity of the UE when receiving transmission block is also different.Therefore, in order to enable carrying out the UE that received UE is emitted when reception There is comparable receptivity when the transport block size difference of transmitting and/or when the UE emitted does transmission power control, It can increase that length is longer and/or the number of retransmissions of the lesser transmission block of transmission power, adjust final code rate, therefore, base station root The number of retransmissions of data is determined according to parameter preset.The parameter preset may include: signal-to-noise ratio, the transmission block bit number or Any one of number of retransmissions mapping table of the data or any combination.

The pattern that base station uses when can be by sending pattern instruction message, instruction UE transmission SA or data to UE, the figure Sample includes the information of the number of retransmissions of SA or data, wherein number of retransmissions is the time resource unit for transmitting SA or data occupancy Quantity, specifically, pattern instruction message can serve to indicate that the serial number of pattern.The resource distribution mode that base station is indicated to UE can be with It is pattern, which is that the two-dimentional resource sequence of finite length comprising one or more time-frequency domains and/or frequency domain have limit for length The one dimensional resource sequence of the finite length of the one dimensional resource sequence and/or time domain of degree, the pattern that instruction UE is used when base station, UE According to the limited of the one dimensional resource sequence of the finite length of the two-dimentional resource sequence of the finite length of time-frequency domain or frequency domain or time domain The length of the one dimensional resource sequence of length can determine the number of retransmissions of SA or data, and base station no longer needs to the field signals by display UE, i.e. base station are implicitly notified of the number of retransmissions of UE data.

The UE emitted retransmits the SA or data to received UE is carried out according to the information of number of retransmissions.

The frequency domain granularity that the resource distribution mode can be SA and/or data occupy, refers to shared by the frequency domain of primary distribution RB quantity.Such as: in the resource pool of the first granularity resource method of salary distribution, UE carries out the frequency domain resource distributed when the direct-connected communication of UE It is all 4RB, in the resource pool of the second granularity resource method of salary distribution, the frequency domain resource of distribution when UE carries out UE direct-connected communication is all 6RB。

The time domain granularity that the resource distribution mode can be SA and/or data occupy.Such as: the first granularity resource distribution side In the resource pool of formula, the time-domain resource that UE distribute when the direct-connected communication of UE is all 4 time quantums (subframe), second It spends in the resource pool of resource distribution mode, the time-domain resource of distribution when UE carries out UE direct-connected communication is all 6 time quantums (subframe)。

UE receives the resource distribution mode of base station instruction.

Step S702, the first UE receive the first scheduling information that the base station is sent, and first scheduling information is used In the time domain and/or frequency resource element that indicate that the SA of the UE is occupied under corresponding resource distribution mode；And/or described One scheduling information is also used to indicate the time domain and/or frequency domain resource that the data of the UE occupy under corresponding resource distribution mode Unit.

Step S703, time domain and/or the frequency domain money that the first UE is occupied under the corresponding resource distribution mode of the SA The SA is sent to the 2nd UE on source；And/or the first UE occupied under the corresponding resource distribution mode of the data when The data are sent to the 2nd UE on domain and/or frequency domain resource.

Specifically, which includes start position information, and initial position message is used to indicate SA in corresponding resource The initial position of band occupancy under the method for salary distribution；Initial position message may be used to indicate that data in corresponding resource distribution mode The initial position of the frequency band of lower occupancy.Due to SA and the frequency bandwidth of data, that is, frequency domain resource granularity passed through it is corresponding Resource distribution mode instruction, therefore, base station only need the initial position of instruction SA or data difference band occupancy, and base station passes through less Bit number can also explicitly indicate that UE sends dispatching distribution and data, save the signaling overheads of base station.UE can in SA or The initial position of the frequency band occupied under the corresponding resource distribution mode of data accurately sends SA or data to another UE.

As further refinement, UE can also receive bit field or height of the base station by the Downlink Control Information Layer signaling indicates that the UE data are poor relative to the time domain time quantum quantity of dispatching distribution, then single according to the time domain time First quantity is poor, successively sends the dispatching distribution and data to the 2nd UE of UE.

In the present embodiment, UE receives the data of the UE of bit field or high-level signaling instruction of the base station by Downlink Control Information Time domain time quantum quantity relative to dispatching distribution is poor, for example, by indicating that information indicates that the time domain time quantum quantity is poor.

It optionally, can also the time domain time quantum quantity be poor by pattern implicit instruction.The pattern be comprising one or The two-dimentional resource sequence of the finite length of multiple time-frequency domains or the one dimensional resource sequence of frequency domain/time domain finite length, base station Without the UE that is emitted of field signals by showing, need to only indicate the resource pattern used, the UE emitted according to when The length of the one dimensional resource sequence of the two-dimentional resource sequence or time domain of frequency domain can determine the time quantum quantity of data, i.e. base station is hidden Formula is notified of the time quantum quantity of the UE data emitted.
