Embodiment 2

Referring to Fig. 2, a kind of method of dispatch request is present embodiments provided, including：

201：Present terminal equipment receives the first information that network side equipment is sent, and the first information is used to notify that first is common Resource is enjoyed, first shared resource is used for terminal device and sends SR, is that network side equipment configures for multiple terminal devices, and should Multiple terminal devices include present terminal equipment；

202：In above-mentioned first shared resource SR is sent to network side equipment；

203：It is that above-mentioned multiple terminal devices distribute the second shared resource for upstream data in network side equipment, or After distributing the private resource for upstream data for present terminal equipment, sent in second shared resource or private resource Row data are to network side equipment.

Above-mentioned terminal device is the equipment of user side, is included but is not limited to：UE, the embodiment of the present invention do not do specific limit to this It is fixed.

The present embodiment gets the resource by network side equipment in the resource for having the SR time-divisions to match somebody with somebody upstream data, terminal device For subsequently sending upstream data, the waste of upstream data resource is largely avoid, improves the utilization of upstream data resource The transmission success rate of rate and upstream data.

Below eNB with network side equipment, exemplified by terminal device is UE, illustrate respectively under different application scenarios how How upstream data is sent to the resource of terminal device allocation schedule request and the resource of upstream data, and terminal device.Should Whether whether different application scenarios refer to network side equipment to the shared resource allocation identification for dispatch request and to eventually End equipment distribution index number.Wherein, eNB can be replaced by the miscellaneous equipment with identical function, and UE can also be by with phase The miscellaneous equipment of congenerous is replaced, and implementation process is identical, do not do excessive explanation herein.

Embodiment 3

Referring to Fig. 3, a kind of method of dispatch request is present embodiments provided, had both been asked applied to eNB without to for dispatching The shared resource allocation identification asked, also the not no scene to UE distribution index number, is specifically included：

301：ENB is a the first shared resource for being used for dispatch request of multiple UE configurations, and it is more to this to send the first information Individual UE, the first information are used to notify UE first shared resources.

Wherein, eNB can be according to the QoS of each UE business established（Quality of Service, service quality） It is required that, at least one of the factor such as the strategy of quantity and eNB of service feature, UE position or channel quality and SR resources, Determine which UE shares a SR resources.The business that UE is established includes but is not limited to：WWW（World Wide Web, Wan Wei Net）Business, FTP（File Transfer Protocol, FTP）Business, SMS（Short Messaging Service, short message service）Business etc., the embodiment of the present invention is not specifically limited to this.In addition, the business in UE was carried out Cheng Zhong, eNB can also be adjusted, and such as decrease or increase shared SR UE quantity, and special SR resources are such as distributed for UE Rather than using shared SR resources etc., preferably to ensure UE QoS and/or preferably utilize SR resources.

Specifically, eNB can pass through RRC（Radio Resource Control, radio resource control）Message, MAC（Media Access Control, medium access control）Message or physical layer message, the first information is sent to the plurality of UE, to notify the plurality of UE first shared resources, the first information includes but is not limited to：Resource, sequence, cycle etc., this hair Bright embodiment is not specifically limited to this.

302：After each UE in above-mentioned multiple UE receives the RRC information, MAC message or physical layer message, extraction is simultaneously The first information is stored, in case subsequently initiating dispatch request according to the first information.

303：Any one UE in above-mentioned multiple UE is sent out when meeting default trigger condition in first shared resource SR is sent to eNB.

Wherein, the trigger condition refers to the trigger condition of dispatch request, can as needed pre-set, such as be provided with Upstream data initiates SR when sending, and initiates SR when either having the data of higher priority to reach or have sent SR before, but UL Grant are not received in a period of time（Uplink authorization）, SR etc. is initiated after overtime, the embodiment of the present invention is not done to this to be had Body limits.

In the present embodiment, further, eNB can also be that the multiple UE for sharing the resource distribute different timer values （SR-Prohibit Timer values）, and notified by RRC information, MAC message or physical layer message to UE.When UE is first at this After sending SR in shared resource, the timer can be started, before the timer expiry, if expired without SR new trigger condition Foot, then do not retransmit SR, if SR new trigger condition meets, then sends SR again；After timer expiry, if SR works as Preceding trigger condition is still met, then continues to send SR；The timer is restarted when UE sends SR again.By being somebody's turn to do to be shared Multiple UE of resource configure different timers and can avoid no longer conflicting when sending SR again after conflicting, so as to reduce continuous punching Prominent probability.

Wherein, trigger condition current SR refers to the default trigger condition described in 203 steps, SR new triggering bar Part refers to default other conditions different from the current trigger-condition.

304：ENB receives the SR in first shared resource, because the resource is that multiple UE share, therefore eNB The SR received may be that a UE in the plurality of UE is sent, it is also possible to the SR that at least two UE are sent simultaneously.

305：It is above-mentioned first shared resource allocation identification not have due to eNB, does not also give UE allocation identification call numbers, because This, after eNB receives SR, can not judge that the SR is one or multiple UE and sent, and be sent by which UE, so ENB distributes the private resource for upstream data according to C-RNTI at least one UE in above-mentioned multiple UE.

Specifically, eNB can give each UE individually to send a PDCCH order, and be entered respectively with respective UE C-RNTI Row, which adds, to be covered, in order to the PDCCH orders that each UE is received with the C-RNTI solutions of oneself, so as to obtain the use that eNB is oneself distribution In the information of the private resource of upstream data.

Wherein, eNB is when at least one UE in above-mentioned multiple UE distributes the private resource for upstream data, can be with NDI is set（New Data Indicator, new data instruction）For new data transmission, that is, it is arranged to use C-RNTI with last The NDI values set during scheduling are different.The NDI is located in PDCCH orders, and UE determines it is the new upper line number of transmission according to the instruction According to, or the upstream data of bust this is retransmitted.In this step, it is instruction that NDI is arranged to new data transmission by eNB It is to make with the last time that UE, which utilizes this to be used to the private resource of upstream data transmit new upstream data to eNB, NDI specific value, NDI values when being dispatched with C-RNTI are different.For example, eNB distributes the shared resource for upstream data to UE1 and UE2, if ENB is last to dispatch NDI=0 set during UE1, then sets NDI=1 during this scheduling UE1, represent new data transmission；If eNB NDI=1 set during last time scheduling UE2, then NDI=0 is set during this scheduling UE2, represents new data transmission.In addition, eNB bases In needs, it is also possible to send the re-transmission of data, the NDI values and upper one in now PDCCH orders before dispatching some or some UE NDI values during secondary scheduling UE are identical.

306：Any one UE in above-mentioned multiple UE monitors the PDCCH orders from eNB after SR is sent, if prison The PDCCH orders for being added with the C-RNTI for distributing to oneself and being covered have been heard, then have shown that eNB is assigned with for upstream data to oneself Private resource, therefore, the UE carry out transmitting uplink data on the private resource.If new data transmission, then meeting SR Cancellation condition after cancel SR.

307：ENB receives the upstream data on the private resource, special to this if successfully solving the upstream data The UE feeding back ACKs message corresponding to resource, if not solving the upstream data, fed back to UE corresponding to the private resource NACK message, it can subsequently require that the UE retransmits or abandoned the upstream data as needed.

The present embodiment gets the resource by network side equipment in the resource for having the SR time-divisions to match somebody with somebody upstream data, terminal device Upstream data is sent using the resource afterwards, compared with prior art, the occupancy to PUSCH resources is reduced, largely avoid The waste of row data resource, improve the utilization rate of upstream data resource and the transmission success rate of upstream data.Pass through distribution The private resource of upstream data, can avoid conflict generation, and avoid due to conflict terminal device keep out of the way after retransmit band The time delay come.By being sent out again to share after the different timer of the multiple terminal devices of SR resources configuration can avoid conflict No longer conflict when sending SR, so as to reduce the probability of consecutive collision.During with traditional SR flows by reducing SR cycle to reduce Prolong and compare, the occupancy to SR resources can be greatly reduced, improve the number of users of receiving.Using the side of dispatch request shared resource Formula, code word interval can be increased, the interference between SR resources be reduced, so as to improve SR decoding performance.

Embodiment 4

Referring to Fig. 4, a kind of method of dispatch request is present embodiments provided, being total to for dispatch request is given applied to eNB Resource allocation is enjoyed to identify, but the not scene to UE distribution index number, specifically include：

401：ENB is a first shared resource of multiple UE configurations, and first shared resource is used for UE and sends SR, and to be somebody's turn to do First shared resource distributes a SR-RNTI（Scheduling Request Cell Radio Network Temporary Identifier, dispatch request Radio Network Temporary Identifier）.

Wherein, how eNB specifically determines which UE shares a SR resources, identical with the description in embodiment 3.

402：The first information is sent to the plurality of UE by eNB, to notify above-mentioned first shared resource, is wrapped in the first information Include the SR-RNTI of above-mentioned distribution.

Wherein, eNB specifically how by the first information be sent in the plurality of UE, and the first information except SR-RNTI with Outer content is identical with the description in embodiment 3.

403：After each UE in above-mentioned multiple UE receives the first information, the first information is stored, in case follow-up root Dispatch request is initiated according to the first information.

404：Any one UE in above-mentioned multiple UE is sent out when meeting default trigger condition in first shared resource SR is sent to eNB.

In the present embodiment, further, eNB can also be that the multiple UE for sharing the resource distribute different timer values （SR-Prohibit Timer values）, and notified by RRC information, MAC message or physical layer message to UE.UE can be according to this Timer and SR trigger condition decide whether to continue to send SR, or cancel SR, specifically with the description in embodiment 3.It is logical Cross and no longer conflict to share multiple UE of the resource and configuring when different timers can avoid and send SR again after conflicting, so as to Reduce the probability of consecutive collision.

405：ENB receives the SR in first shared resource, because the resource is that multiple UE share, therefore eNB The SR received may be that a UE in the plurality of UE is sent, it is also possible to the SR that at least two UE are sent simultaneously.

406：Because eNB is not UE allocation identification call numbers, therefore, after eNB receives SR, it is which that can not judge the SR What individual UE was sent, may determine that it is the SR from shared resource according to SR-RNTI, so eNB is above-mentioned more according to C-RNTI At least one UE in individual UE distributes the private resource for upstream data, or is distributed according to SR-RNTI for above-mentioned multiple UE For the second shared resource of upstream data, wherein, the order includes specific running time-frequency resource, MCS（Modulation and Coding Scheme, modulation coding mode）, TB（Transport Block, transmission block）Size etc., power can also be included and believed Breath.

When eNB distributes the private resource for upstream data, specifically, each UE can be given individually to send one PDCCH orders, and carried out plus covered respectively with respective UE C-RNTI, received in order to each UE with the C-RNTI solutions of oneself PDCCH orders, so as to obtain the information for the private resource for upstream data that eNB is oneself distribution.Wherein, eNB distribution is used When the private resource of upstream data, it is new data transmission that can set NDI, that is, is arranged to dispatch using C-RNTI with the last time When the NDI values that set it is different.

When eNB distributes the second shared resource for upstream data, only need to send one adds what is covered with SR-RNTI PDCCH orders, after each UE receives the PDCCH orders, the SR-RNTI stored with oneself solves the PDCCH orders, so as to To the information for the second shared resource for upstream data that eNB is distribution.Wherein, can be with when eNB distributes the second shared resource The value for setting NDI is default value, indicates new data transmission, is such as arranged to 0 or 1 and represents new data transmission.

407：Any one UE in above-mentioned multiple UE monitors the PDCCH orders from eNB, judges to supervise after SR is sent Whether the PDCCH orders heard are to add what is covered with the C-RNTI for distributing to oneself, if it is, performing 408；Otherwise, perform 410。

408：Now show that eNB is assigned with the private resource for upstream data to current UE, therefore, the UE is special at this Transmitted over resources upstream data is to eNB.Wherein, current UE refers to that any one current PDCCH that listens in above-mentioned multiple UE is ordered The UE of order, specifically, NDIs of the UE in the PDCCH orders carry out new data transmission, and current UE is no longer in this TTI Whether monitoring receives the PDCCH orders covered being added with SR-RNTI from eNB.If new data transmission, then meeting taking for SR Cancel SR after the condition that disappears.

409：ENB receives the upstream data from the private resource, special to this if successfully solving the upstream data UE feeding back ACKs message corresponding to resource, if not solving the upstream data, feed back NACK to UE corresponding to the private resource Message, it can subsequently require that the UE is retransmitted or abandoned the upstream data as needed, flow terminates.

410：Whether the PDCCH orders that current UE judges to listen to are added with SR-RNTI is covered, if it is, showing eNB The second shared resource for upstream data is assigned with to current UE, therefore, the UE sends up in second shared resource Data carry the C-RNTI of oneself to eNB in the upstream data.Specifically, UE adds what is covered according to this with SR-RNTI NDI in PDCCH orders carries out new data transmission.Wherein, UE can record the value of the NDI, can not also record the NDI's Value.If new data transmission, then cancel SR after SR cancellation condition is met；Or if new data transmission, and The ACK that eNB is returned is received after sending data, then cancels SR after SR cancellation condition is met.

Further, this step can also be replaced by following steps：

Current UE judges whether to receive eNB for current UE in current TTI（Transmission Time Interval, Transmission Time Interval）The NACK message that the upstream data sent before returns, if it is, sent before showing current UE Upstream data fails, and therefore, the PDCCH orders that being added with SR-RNTI from eNB cover is not listening in current TTI, i.e., current First the re-transmission of the upstream data of failure is sent before carrying out as needed, from next TTI without new data transmission in TTI The PDCCH orders whether monitoring receives being added with SR-RNTI from eNB and cover are started or continued to, if it is, in eNB distribution Upstream data is sent in the shared resource of upstream data to eNB, carries out new data transmission.

411：ENB receives the upstream data from second shared resource, if successfully solving the upstream data, passes through PHICH feeding back ACK message, if not solving the upstream data, NACK message is fed back by PHICH, subsequently can basis The requirement UE is needed to retransmit or abandon the upstream data, flow terminates.

Further, after 411, can also comprise the following steps：

When eNB judges to have multiple UE in the second shared resource while sends upstream data, or, when eNB does not exist When upstream data is successfully solved in the second shared resource, then it is assumed that clash, eNB can redistribute portion and be used for upper line number According to private resource to current UE, current UE is used to retransmit above-mentioned upstream data to eNB on private resource of upstream data at this. If eNB receives eNB's to current UE, current UE without distribution upstream data private resource after conflict by PHICH After NACK message, SR can be then resend with random back for a period of time, to ask ascending resource again, or configured After timer SR-ProhibitTimer time-out, SR is resend, to ask ascending resource again.Wherein, the back off time It can be that random or network side configures, can be the value of UE oneself configurations or UE 0 to configuration Between random selection, the embodiment of the present invention is not specifically limited to this.Further, UE SR number of transmission can also be set Threshold value, after the number that UE sends SR reaches the threshold value, then SR is not retransmited, random access procedure can be triggered.

In the present embodiment, for any UE, if listening to the PDCCH orders that being added with SR-RNTI from eNB cover, The PDCCH orders that being added with SR-RNTI from eNB cover no longer are monitored since next TTI, after sending SR again again Begin listening for.

In the present embodiment, UE begins listening for the time for the PDCCH orders that being added with SR-RNTI from eNB cover and UE is sent SR time has a minimum interval, is generally all 4 TTI, i.e. UE after 4 TTI, is just opened after it have sent SR Begin to monitor the PDCCH orders for SR-RNTI being added and being covered, the specific value embodiment of the present invention at the interval is not specifically limited.For Monitored with C-RNTI plus the PDCCH orders covered, UE, because being that the resource is special, will not be produced with other UE at any time Raw conflict.

In the present embodiment, any one UE, can be as in the associative operation that some TTI is monitored and sent after SR is sent Shown in table 1.

Table 1

Wherein, when UE, which listens to, adds the PDCCH orders covered with C-RNTI, if UE is transmitted across data before, no matter ENB feedbacks are ACK, or NACK, then UE carries out the transmission of new data all in accordance with C-RNTI, and no longer monitors and use in this TTI SR-RNTI adds the PDCCH orders covered.When UE, which does not listen to, adds the PDCCH orders covered with C-RNTI, if UE is sent before Data are crossed, then when the data before eNB feeding back ACKs show are sent successfully, this TTI monitors SR-RNTI and adds the PDCCH covered to order Order, listen to when adding the PDCCH orders covered with SR-RNTI, according to SR-RNTI progress new data transmissions；NACK tables are fed back in eNB When data before bright send failure, it can be chosen any one kind of them in following two operations：1）The up of failure is sent before retransmitting Data, this TTI, which is no longer monitored and started or continued to monitoring SR-RNTI from next TTI, adds the PDCCH orders covered；2）This TTI Monitor and add the PDCCH orders covered with SR-RNTI, listen to when adding the PDCCH orders covered with SR-RNTI, carried out according to SR-RNTI New data transmission, the data of failure are sent before abandoning.

The present embodiment gets the resource by network side equipment in the resource for having the SR time-divisions to match somebody with somebody upstream data, terminal device Upstream data is sent using the resource afterwards, compared with prior art, the occupancy to PUSCH resources is reduced, largely avoid The waste of row data resource, improve the utilization rate of upstream data resource and the transmission success rate of upstream data.

When the private resource of distribution upstream data, the generation of conflict can be avoided, and is avoided because conflict terminal is set It is standby keep out of the way after retransmit the time delay brought.By distributing shared resource that SR-RNTI can distribute upstream data to terminal device, with Traditional SR flows are compared by reducing SR cycle to reduce time delay, can greatly reduce the occupancy to SR resources, are improved and are held The number of users received.By the way of dispatch request shared resource, code word interval can be increased, reduce the interference between SR resources, So as to improve SR decoding performance.By that can be avoided to share the different timer of the multiple terminal devices of SR resources configuration No longer conflict when sending SR after conflict again, so as to reduce the probability of consecutive collision.

During the upstream data failure sent before terminal device, it is not listening to use SR- from eNB in current TTI RNTI adds the PDCCH orders covered, can cause terminal device preferentially carry out before data re-transmission, avoid new due to directly carrying out Data transfer and before causing data loss.The terminal for the PDCCH orders covered is added to set with SR-RNTI for any listen to It is standby, the PDCCH orders for being added with SR-RNTI and being covered no longer are monitored since next TTI, restart to supervise after sending SR again Listen, avoid and be assigned with the shared resource of upstream data after receiving other UE SR at other moment due to eNB, and cause at this Data are sent in the shared resource of upstream data so as to be clashed with other UE.

Embodiment 5

Referring to Fig. 5, a kind of method of dispatch request is present embodiments provided, being total to for dispatch request is given applied to eNB Resource allocation mark is enjoyed, and the scene of call number is assigned with to UE, is specifically included：

501：ENB is a first shared resource of multiple UE configurations, and first shared resource is used for UE and sends SR, and to be somebody's turn to do Each UE in multiple UE distributes a call number, can also be that first shared resource distributes a SR-RNTI optionally.

ENB is used to identify specific UE to the call number that UE is distributed, and each UE call number is unique.For example, have 2 Individual UE shares a resource, then call number can be 0,1, and the embodiment of the present invention is not specifically limited to this.

502：ENB sends the first information to the plurality of UE, to notify above-mentioned first shared resources of the plurality of UE, first letter Breath includes each UE call number, if being assigned with SR-RNTI, also includes the SR-RNTI of above-mentioned distribution.

Wherein, eNB specifically how the first information is sent in the plurality of UE, and the first information except SR-RNTI and Content beyond each UE call number is identical with the description in embodiment 3.

Further, in the present embodiment, eNB can also notify that this is first shared by UE when sending the first information to UE The form of resource, specifically, UE can be notified by PUCCH Format parameters, such as utilize PUCCH Format1a notices UE Share 2 UE and share the resource, 1a carries 1bit effective information, can identify 2 UE；Or utilize PUCCH Format1b Notice UE shares 4 UE and shares the resource, and 1b carries 2bit effective information, can identify 4 UE.Alternatively, it is also possible to basis Need to extend new PUCCH Format to identify the shared resource of more UE numbers, the embodiment of the present invention is not done this specifically Limit.

503：After each UE in above-mentioned multiple UE receives the first information, the first information is stored, in case follow-up root Dispatch request is initiated according to the first information.

504：Any one UE in above-mentioned multiple UE is sent out when meeting default trigger condition in first shared resource SR is sent to eNB, and carries the call number that eNB is oneself distribution wherein.

505：ENB receives the SR in first shared resource, because the resource is that multiple UE share, therefore eNB The SR received may be that a UE in the plurality of UE is sent, it is also possible to the SR that at least two UE are sent simultaneously.

506：ENB judges that the SR that receives is that a UE is sent, or multiple UE are sent, if a UE is sent , perform 507；Otherwise, 508 are performed.

507：If the SR that eNB is received is the SR that a UE in above-mentioned multiple UE is sent, i.e., no conflict occurred, then The SR that specifically which UE is sent can be determined according to the call number carried in the SR, and distributed for the UE for upstream data Private resource, specifically, the C-RNTI of the UE can be used to add the PDCCH orders covered to notify UE, then perform 509.

508：If the SR that eNB is received is at least two UE in above-mentioned multiple UE while the SR sent, that is, show have Conflict occur, then specifically which UE can not be solved and have sent SR by eNB, therefore, according to C-RNTI be above-mentioned multiple UE in extremely A few UE distributes the private resource for upstream data, or in the case where being assigned with SR-RNTI, is according to SR-RNTI Above-mentioned multiple UE distribute the second shared resource for upstream data, wherein, the order includes specific running time-frequency resource, MCS, TB sizes etc., power information can also be included, then perform 509.

When eNB distributes the private resource for upstream data, specifically, each UE can be given individually to send one PDCCH orders, and carried out plus covered respectively with respective UE C-RNTI, received in order to each UE with the C-RNTI solutions of oneself PDCCH orders.Wherein, it is new data transmission that eNB can set NDI in PDCCH orders, that is, is arranged to use C- with last The NDI values that RNTI is set when dispatching are different.In addition, eNB is based on needing, it is also possible to sends data before dispatching some or some UE Re-transmission, NDI values in now PDCCH orders with it is last dispatch the UE when NDI values it is identical.

When eNB distributes the second shared resource for upstream data, only need to send one adds what is covered with SR-RNTI PDCCH orders, after each UE receives the PDCCH orders, the SR-RNTI stored with oneself solves the PDCCH orders.Wherein, eNB can To set NDI value to indicate new data transmission as default value in PDCCH orders, such as it is arranged to 0 or 1 and represents new data biography It is defeated.

509：Any one UE in above-mentioned multiple UE monitors the PDCCH orders from eNB, judges to supervise after SR is sent Whether the PDCCH orders heard are to add what is covered with the C-RNTI for distributing to oneself, if it is, performing 510；Otherwise, perform 512。

510：Now show that eNB is assigned with the private resource for upstream data to current UE, therefore, the UE is special at this Transmitted over resources upstream data is to eNB.Wherein, current UE refers to that any one current PDCCH that listens in above-mentioned multiple UE is ordered The UE of order, specifically, NDIs of the UE in the PDCCH orders carry out new data transmission, and current UE is no longer in this TTI Whether monitoring receives the PDCCH orders covered being added with SR-RNTI from eNB.If new data transmission, then meeting taking for SR Cancel SR after the condition that disappears.

511：ENB receives the upstream data from the private resource, special to this if successfully solving the upstream data UE feeding back ACKs message corresponding to resource, if not solving the upstream data, feed back NACK to UE corresponding to the private resource Message, it can subsequently require that the UE is retransmitted or abandoned the upstream data as needed, flow terminates.

512：Whether the PDCCH orders that current UE judges to listen to are added with SR-RNTI is covered, if it is, showing eNB The second shared resource for upstream data is assigned with to current UE, therefore, the UE sends up in second shared resource Data carry the C-RNTI of oneself to eNB in the upstream data.Specifically, UE adds what is covered according to this with SR-RNTI NDI in PDCCH orders carries out new data transmission.Wherein, UE can record the value of the NDI, can not also record the NDI's Value.If new data transmission, then cancel SR after SR cancellation condition is met；Or if new data transmission, and The ACK that eNB is returned is received after sending data, then cancels SR after SR cancellation condition is met.

Further, this step can also be replaced by following steps：

Current UE judges whether to receive what eNB returned for the upstream data that current UE has been sent before current TTI NACK message, if it is, the upstream data failure sent before showing current UE, therefore, is not listening to come from current TTI ENB's adds the PDCCH orders covered with SR-RNTI, i.e., first carries out it as needed without new data transmission in current TTI Whether the re-transmission of the preceding upstream data for sending failure, next TTI start or continue to monitor to receive to use SR-RNTI from eNB Add the PDCCH orders covered, if it is, sending upstream data in the second shared resource of eNB distribution to eNB, newly counted According to transmission.

513：ENB receives the upstream data from second shared resource, if successfully solving the upstream data, passes through PHICH feeding back ACK message, if not solving the upstream data, NACK message is fed back by PHICH, subsequently can basis The requirement UE is needed to retransmit or abandon the upstream data, flow terminates.

Further, in the present embodiment after 513, can also comprise the following steps：

When eNB judges to have multiple UE in the second shared resource while sends upstream data, or, when eNB does not exist When upstream data is successfully solved in the second shared resource, then it is assumed that clash, eNB can redistribute portion and be used for upper line number According to private resource to current UE, current UE is used to retransmit above-mentioned upstream data to eNB on private resource of upstream data at this. Wherein, eNB can set NDI to retransmit when redistributing the private resource for upstream data.If eNB is after conflict Upstream data private resource is not distributed to current UE, then, can be with after current UE receives eNB NACK message by PHICH Random back for a period of time, then resends SR, to ask ascending resource again, or is being configured with timer SR- After ProhibitTimer time-out, SR is resend, to ask ascending resource again.Wherein, the back off time can be random Or network side configuration, can be UE oneself configurations or UE random between 0 to configuration value Selection, the embodiment of the present invention are not specifically limited to this.Further, UE can also be set to send the threshold value of SR number, work as UE After transmission SR number reaches the threshold value, then SR is not retransmited, random access procedure can be triggered.

In the present embodiment, UE begins listening for the time for the PDCCH orders that being added with SR-RNTI from eNB cover and UE is sent SR time has a minimum interval, is all generally 4 TTI, the specific value embodiment of the present invention at the interval, which is not done, to be had Body limits.For adding the PDCCH orders covered with C-RNTI, UE is monitored at any time because be the resource be it is special, will not Produce and conflict with other UE.

In the present embodiment, any one UE, can be as in the associative operation that some TTI is monitored and sent after SR is sent Shown in above-mentioned table 1, detailed process is with the explanation in embodiment 4, and here is omitted.

When the private resource of distribution upstream data, the generation of conflict can be avoided, and is avoided because conflict terminal is set It is standby keep out of the way after retransmit the time delay brought.By distributing shared resource that SR-RNTI can distribute upstream data to terminal device, with Traditional SR flows are compared by reducing SR cycle to reduce time delay, can greatly reduce the occupancy to SR resources, are improved and are held The number of users received.

It can directly determine which UE the SR comes from when receiving a SR by the call number of distribution terminal equipment, carry The high efficiency of dispatch request.By the way of dispatch request shared resource, code word interval can be increased, reduced between SR resources Interference, so as to improve SR decoding performance.By configuring different timers to share the multiple terminal devices of the SR resources It can avoid no longer conflicting when sending SR again after conflicting, so as to reduce the probability of consecutive collision.

During the upstream data failure sent before terminal device, it is not listening to use SR- from eNB in current TTI RNTI adds the PDCCH orders covered, can cause terminal device preferentially carry out before data re-transmission, avoid new due to directly carrying out Data transfer and before causing data loss.The terminal for the PDCCH orders covered is added to set with SR-RNTI for any listen to It is standby, no longer monitor to add the PDCCH orders covered with SR-RNTI since next TTI, restart after sending SR again Monitor, avoid the shared resource due to receiving the up shared data being assigned with after other UE SR at other moment in eNB, And cause to send data in the shared resource of the upstream data so as to clash with other UE.

In the method that above-described embodiment provides, UE sends SR and transmission upstream data can be in same TTI, can also This is not specifically limited in same TTI, the embodiment of the present invention.When UE can not send SR and up in same TTI During data, the eNB for receiving upstream data may determine that the UE in the TTI certainly without transmission SR.

In the method that above-described embodiment provides, if eNB is in the multiple UE for sharing the SR resources are given after receiving SR During the private resource of at least one distribution upstream data, it can be determined according to default rule to which of the plurality of UE UE points Private resource with upstream data.Specifically, it can be determined that whether there is UE not to be transmitted across SR, if so, then for not being transmitted across SR UE, the private resource that can not distribute upstream data are not dispatched, or, new biography or the tune of re-transmission are carried out as needed Degree.For example, if some UE upstream data can not be sent with SR in same TTI, when eNB receives the UE in some TTI Upstream data, and when receiving the SR in SR shared resources, wherein, sharing multiple UE of the SR resources includes sending The UE of row data, then eNB can determine that the UE does not send SR in the TTI, therefore, can not give the UE distribute it is up Whether the private resource of data, further, the upstream data for the UE that can also judge to receive correctly solve, if it is, Feeding back ACK, at this point it is possible to which dispatching the UE carries out new biography；Otherwise, NACK is fed back, is retransmitted at this point it is possible to dispatch the UE.

In the method that above-described embodiment provides, if to add the PDCCH orders covered to be assigned with by SR-RNTI up by eNB After second shared resource of data is to UE, after UE sends upstream data using second shared resource, if eNB is not solved successfully Go out the upstream data, then feed back NACK to UE, and it is up to share at least one UE distribution in multiple UE of the SR resources The private resource of data.Specifically, the TB size phases of the private resource of the upstream data and the second shared resource distributed before Together, other parameters such as MCS can be different.If eNB was also used other up before above-mentioned second shared resource is distributed Data private resource is scheduled to current UE, then during this sub-distribution upstream data private resource, can use following two sides Any of formula sets NDI.

First way, in the private resource of this sub-distribution upstream data, by NDI values therein be arranged to before NDI value is identical when distributing the second shared resource, represents to retransmit.The second way, in the special of this sub-distribution upstream data During resource, NDI values therein are arranged to the value phase with NDI when last time distributes the private resource of upstream data before Together.The first TTI is designated as at the time of the private resource that upstream data will be distributed before, upstream data will be distributed after the first TTI Shared resource at the time of be designated as the 2nd TTI, the is designated as at the time of the private resource that upstream data will be distributed after the 2nd TTI Three TTI, then eNB set NDI and UE understand NDI detailed process as shown in table 2 and table 3.Wherein, table 2 corresponding above-mentioned first Kind mode, the corresponding above-mentioned second way of table 3, moreover, between can having the time between the first TTI, the 2nd TTI and the 3rd TTI Every the numerical value embodiment of the present invention at the interval is not specifically limited to this.Wherein, the 3rd TTI is the above-mentioned up number of sub-distribution According to private resource at the time of.

Wherein, eNB is assigned with the second shared resource of upstream data at the 2nd TTI moment, and wherein NDI value is as needed 0 or 1 is could be arranged to, represents new data transmission.After having UE to send data in second shared resource, eNB is due to solving data Failure, the private resource of upstream data is assigned with the 3rd TTI moment, wherein NDI value is arranged to and the 2nd TTI moment again The value of NDI during the shared resource of distribution upstream data is identical, represents and retransmits.If for example, the 2nd TTI moment NDI=0th, sets Put the 3rd TTI moment NDI=0th；If the 2nd TTI moment NDI=1st, the 3rd TTI moment NDI=1st is set.

UE for sending SR, data failure is transmitted using above-mentioned second shared resource, is distributed when receiving for the 3rd TTI moment Private resource when, can by the NDI values compared with the NDI values for the private resource that the first TTI moment distributed before, with determine Do new data transmission or retransmit, if result of the comparison is identical, retransmitted, if result of the comparison is different, Then carry out new data transmission.

For no transmission SR and without the UE using above-mentioned second shared resource transmission data, when receiving three TTI Carve distribution private resource when, can by the NDI values compared with the NDI values for the private resource that the first TTI moment distributed before, To determine to do new data transmission or retransmit, if result of the comparison is identical, retransmitted, if result of the comparison Difference, then carry out new data transmission.

Table 3

Wherein, eNB is assigned with the second shared resource at the 2nd TTI moment, and wherein NDI value could be arranged to as needed 0 or 1, represent new data transmission.After having UE to send data in second shared resource, eNB is due to solving data failure, the 3rd The TTI moment is assigned with the private resource of upstream data again, and wherein NDI value is arranged to distribute line number with the first TTI moment According to private resource when NDI value it is identical, represent retransmit.If for example, the first TTI moment NDI=0th, sets the 3rd TTI Moment NDI=0；If the first TTI moment NDI=1st, the 3rd TTI moment NDI=1st is set.

UE for sending SR, data failure is transmitted using above-mentioned second shared resource, is distributed when receiving for the 3rd TTI moment Private resource when, can by the NDI values compared with the NDI values for the private resource that the first TTI moment distributed before, with determine Do new data transmission or retransmit, in the implementation shown in table 3, result of the comparison is certainly identical, then carries out weight Pass.

For no transmission SR and without the UE using above-mentioned second shared resource transmission data, when receiving three TTI Carve distribution private resource when, can by the NDI values compared with the NDI values for the private resource that the first TTI moment distributed before, To determine to do new data transmission or retransmit, in the implementation shown in table 3, result of the comparison is certainly to be identical, then Retransmitted.

If in the re-transmission order that UE is received, TB sizes are different from transmitted size of data, and UE can not be retransmitted, this If when eNB detect DTX, it is considered that UE do not retransmit data, and then no longer dispatch the re-transmission of the UE.Or eNB exists After detecting DTX, then one or many re-transmissions are dispatched, until reaching default maximum times or thinking that UE does not retransmit data and is Only.

In above two implementation, when UE receives eNB SR-RNTI and adds the PDCCH orders covered, this can be stored NDI in PDCCH orders, the NDI in the PDCCH orders can not also be stored, regardless of whether storage, UE carries out new according to NDI Data transfer or the handling process of re-transmission are identical.
