Abstract
The invention provides a TDD system resource allocation method. After receiving a resource allocation order sent by Node B, a UE allocates or releases the current channel resource according to the order or simultaneously releases current resources and reallocates the channel resource; then the UE sends the resource allocation feedback information to the Node B; whether resource allocation successes or fails is reported to the Node B according to the feedback information; if the Node B does not receive resource allocation feedback information when resource allocation fails or exceeds setting time, the Node B sends the resource allocation order to UE again. The invention also provides a UE and a Node B applying the above resource allocation method. When the resource allocation method, the UEand the Node B provided by the invention are used, under the condition that resource allocation order has transmission errors, the Node B can be informed of that channel resource is not released or allocated in time so as to send the resource allocation order again, thus ensuring that resource allocation can be accurately finished.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of time division duplex (TDD) system resource allocation method and subscriber equipment and base station.
Background technology
At present, the TDD system is used widely in mobile communication.With TD SDMA (TD-SCDMA) is example, comprise two kinds of scheduling of resource modes of dynamic dispatching mode and semi-continuous scheduling mode in the TD-SCDMA standard, in these two kinds of scheduling of resource modes, base station (Node B) all adopts the up absolute grant channel of enhancing (E-AGCH) is subscriber equipment (UE) collocating uplink Radio Resource by the resource distribution order.The resource distribution order comprises: be that UE distributes ascending wireless resource, or indication UE discharges current ascending wireless resource, or indicate UE to discharge current ascending wireless resource simultaneously and distribute ascending wireless resource once more for UE.After UE receives the resource distribution order, resource is configured, specifically comprises: carry out resource allocation or carry out current resource and discharge or carry out current resource simultaneously and discharge and resource sub-distribution again according to this order.For UE distributes ascending wireless resource is that Node B specifies the enhancing physics up channel (E-PUCH) that allows this UE to use by E-AGCH.Wherein, in the dynamic dispatching mode, for UE distributes the ascending wireless resource of finite duration, when arriving the stipulated time, the ascending wireless resource that is distributed discharges automatically, and Node B distributes new ascending wireless resource for UE again; In the semi-continuous scheduling mode, Node B is that UE can use this ascending wireless resource after UE distributed ascending wireless resource, sends the configuration order that the indication ascending wireless resource discharges up to Node B to UE, UE promptly discharges this ascending wireless resource, no longer uses it and sends upward signal.In existing TD-SCDMA standard, the release of the ascending wireless resource that distributes for the semi-continuous scheduling mode, Node B still sends the configuration order that indexed resource discharges by E-AGCH.In the present TD-SCDMA standard, only there is command procedure, can expects,, the resource distribution command procedure of other type also can occur along with the continuous evolution of technology to the resource release of semi-continuous scheduling.
In existing TD-SCDMA standard, the half-persistence scheduling resources configuration is an one-way process, that is: Node B sends the half-persistence scheduling resources configuration order by E-AGCH to UE, and UE receives the configuration that semi-continuous scheduling E-PUCH resource is carried out in this order back.But, do not have the execution result of any mechanism in the existing TD-SCDMA standard to the configuration of Node B feedback resources, therefore, if UE does not receive that the resource distribution order of E-AGCH or the E-AGCH resource distribution order that UE receives are wrong, UE can't carry out the configuration operation of semi-continuous scheduling E-PUCH resource, and it is unsuccessful to Node B report resource distribution not have any mechanism this moment, when the resource distribution order indicates current resource to discharge, this just causes Node B to think that the E-PUCH resource of UE discharges, thereby these resources are distributed to other UE once more to be used, but former UE but still ceaselessly utilizes these resources to send upward signal, be that resource allocation status on UE and the Node B is inconsistent, thereby cause this part resource to be regained, and can cause serious interference other UE even other sub-district by Node B; When resource distribution order indexed resource divides timing, this just causes Node B to think that the E-PUCH resource of UE has become the distribution of work, but UE but can't use these E-PUCH resources to carry out up transmission, thereby causes the wasting of resources.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
In embodiments of the present invention, UE configurating channel resource and send the resource distribution feedback message after receiving the resource distribution order that Node B sends to Node B, report resource distribution success or failure by this message to Node B, when Node B does not still receive the resource distribution feedback message in the resource distribution failure or above setting-up time, send the resource distribution order to UE again.
Resource distribution order described in the embodiment of the invention comprises: be that UE distributes ascending wireless resource, or indication UE discharges current ascending wireless resource, or indicate UE to discharge current ascending wireless resource simultaneously and distribute ascending wireless resource once more for UE.After UE receives the resource distribution order, resource is configured, specifically comprises: carry out resource allocation, or carry out current resource release, or carry out current resource release and resource sub-distribution more simultaneously according to this order.Comprise the first distribution of ascending wireless resource and heavily distribute two kinds of situations for UE distributes ascending wireless resource.
For Node B can accurately be followed the tracks of the implementation status of resource distribution order, in embodiments of the present invention, UE feeds back its execution result to Node B after receiving the resource distribution order.The flow process of embodiment of the invention resource allocation method specifically may further comprise the steps as shown in Figure 1:
Step 101:Node B sends the resource distribution order by E-AGCH to UE.
Step 102:UE is after the resource distribution order of receiving Node B, and the configurating channel resource also sends the resource distribution feedback message to NodeB, by this resource distribution feedback message to Node B report resource distribution success or failure.For example, UE disposes the E-PUCH of semi-continuous scheduling mode and sends the resource distribution feedback message to Node B after the resource distribution order of receiving Node B.
Behind the resource distribution feedback message that step 103:Node B reception UE sends, judge resource distribution success or failure according to the resource distribution feedback message, if resource distribution failure or Node B ultrasonic are crossed setting-up time and still do not received the resource distribution feedback message, then Node B sends the resource distribution order by E-AGCH to UE again.
Further,, can after Node B sends the resource distribution order by E-AGCH, start a timer, for example, this timer is called T_order for the time is calculated and is provided with.According to the selected setting-up time length of the needs of communication system, adopt this setting-up time that timer is set, because timer starts after Node B sends the resource distribution order immediately, so if this timer expiry is not still received the resource distribution feedback that UE sends, then Node B judges the failure of resource distribution command procedure, again send the resource distribution order by E-AGCH to UE, and, restart timer the timer zero clearing.Node B judges the resource distribution success after receiving the resource distribution feedback message that UE sends, the timeing closing device, and will have the timing zero clearing now.
According to above-mentioned resource allocation method, can carry above-mentioned resource distribution feedback message by uplink physical channel.On the basis of existing TD-SCDMA standard, make improvements according to above-mentioned resource allocation method, the uplink physical channel that can be used for carrying the resource distribution feedback message in the above-mentioned steps 102 has following three kinds of selections: selection 1, E-PUCH; Or select 2, high-speed shared information channel (HS-SICH); Or select 3, enhanced uplink random access channel (E-RUCCH).Respectively the resource allocation method that adopts above-mentioned three kinds of channel bearing resource distribution feedback messages is described in detail below.
Channel is selected 1, is adopted E-PUCH to send the resource distribution feedback message.
UE uses E-PUCH to send the resource distribution feedback message two kinds of implementations: mode 1 is to adopt the E-PUCH of semi-continuous scheduling to send the resource distribution feedback message; Mode 2 is to adopt the E-PUCH of dynamic dispatching to send the resource distribution feedback message.Below respectively this dual mode is elaborated.
Mode 1
During employing mode 1, Node B sends the resource distribution order by the E-AGCH of semi-continuous scheduling, that is, this resource distribution order is carried on the E-AGCH subframe; After UE receives the resource distribution order, adopt the E-PUCH of semi-continuous scheduling to send the resource distribution feedback message earlier, this E-PUCH adopts the E-PUCH subframe of the next semi-continuous scheduling after the above-mentioned E-AGCH subframe, that is bearing resource configuration feedback message on the next available semi-continuous scheduling E-PUCH subframe of the E-AGCH of above-mentioned bearing resource configuration order subframe; UE disposes all semi-continuous scheduling E-PUCH resources subsequently after sending the resource distribution feedback message to Node B.
Below introduce the resource distribution order of mode 1 with a specific embodiment, referring to table 1, the subframe order of semi-continuous scheduling mode is as shown in table 1, the subframe of receiving E-AGCH is designated as subframe N, and with subframe N is benchmark mark subframe N-2 respectively, subframe N-1, subframe+1, subframe N+2, subframe N+3...... once is example with semi-continuous scheduling E-PUCH resource every 5 sub-frame allocation, suppose at subframe N-2 carrying E-PUCH, after this E-PUCH sends, UE receives the resource distribution order of E-AGCH at subframe N, so UE just the E-PUCH subframe of the next semi-continuous scheduling after the E-AGCH subframe send the resource distribution message feedback, promptly send the E-PUCH of resource distribution feedback message in subframe N+3 carrying.UE can use whole E-PUCH resources when sending the resource distribution feedback message on subframe N+3, also can be with certain selection principle selected part E-PUCH resource.Can adopt selection principle arbitrarily according to the actual conditions of communication system, only introduce a preferable example in the present embodiment: the spreading factor of fixedly choosing minimum time slot, the lowest number of the semi-continuous E-PUCH resource of original distribution is 8 (SF8) code word bearing resource configuration feedback message, all the other code words in the configuration E-PUCH subframe.

| … | Subframe N-2 | Subframe N-1 | Subframe N | Subframe N+1 | Subframe N+2 | Subframe N+3 | … |
| ?SPS ?E-PUCH | ?E-AGCH | ?SPS ?E-PUCH |
UE can carry by the schedule information (SI) that E-PUCH upward sends to configuration successful or failure that Node B reports by the resource distribution feedback message, there is multiple expression mode in concrete SI information field, can from the multiple expression mode of SI information field, select two kinds arbitrarily, be appointed as expression resource distribution success or failure respectively.In the present embodiment only with following example as an illustration: table 2 is depicted as the information field form of SI, referring to table 2, comprise the highest priority logical channel identify label (HLID) that length is the uplink transmission power surplus (UPH) of this sub-district of 5bits and the path loss difference (SNPL) between the adjacent sub-district, the length UE that is 5bits, buffer data total amount (TEBS) that length is 5bits, length is 4bits highest priority logical channel buffer area data volume (HLBS) and length are 4bits among the SI.Below enumerating 2 represents the preferred embodiments of resource distribution success or failure in actual the setting, still can adopt the expression mode of other SI information field with the SI information field.In example 1, represent that with TEBS=0 this SI message represents the resource distribution feedback message, and in the value state of HLBS＞0, select a value state arbitrarily as the first value state, be used for representing configuration successful, and select a value state different arbitrarily as the second value state with the first value state, be used for representing configuration failure, for example TEBS=0 among the SI and HLBS=5 represent the resource distribution success, and TEBS=0 and HLBS=6 represent the resource distribution failure.In example 2, be 0 expression configuration successful with SI full detail territory, be 1 expression configuration failure with SI full detail territory, also can be that the 0 or 1 represented meaning is exchanged with SI full detail territory, that is, be 1 expression configuration successful with SI full detail territory, be 0 expression configuration failure with SI full detail territory.
The information field form shfft of table 2 SI
| ????SNPL ????(5bits) | ????UPH ????(5bits) | ????TEBS ????(5bits) | ????HLBS ????(4bits) | ????HLID ????(4bits) |
Mode 2
When adopting aforesaid way 2, when Node B passes through E-AGCH down distributing resource configuration order, out of Memory territory by this E-AGCH is the E-PUCH that UE distributes the dynamic dispatching that is used for sending the resource distribution feedback message, UE obtains the E-PUCH that Node B distributes when receiving the resource distribution order, UE configuration semi-continuous scheduling E-PUCH subsequently, the E-PUCH of the dynamic dispatching that distributes by Node B sends the resource distribution feedback message then, to Node B report resource distribution success or failure.
Identical with described in the aforesaid way 1, in mode 2, configuration successful that UE reports to Node B or failure also can be gone up the SI that sends by E-PUCH and be carried, and represent configuration successful or failure by the special value state that SI is set.
Channel is selected 2, is adopted HS-SICH to send the resource distribution feedback message.
If UE sends the resource distribution feedback message by HS-SICH to Node B, then directly utilizing affirmation on the HS-SICH or non-affirmation (ACK/NACK) territory to feed back gets final product, confirm (ACK) expression resource distribution success, non-affirmation (NACK) expression resource distribution failure.
In existing TD-SCDMA standard, the timing relationship that does not have E-AGCH and HS-SICH, so, if adopt HS-SICH to send the resource distribution feedback message to Node B, need to increase the timing relationship of E-AGCH and HS-SICH, promptly be defined on the subframe of subframe setting number afterwards of E-AGCH of bearing resource configuration order and carry HS-SICH.For example, above-mentioned setting number is M, is unit with the subframe, M subframe carrying E-AGCH after the subframe of carrying E-AGCH.With M=3 is example, and the subframe order of E-AGCH and HS-SICH timing relationship is as shown in table 3.
The subframe sequence list of table 3 E-AGCH and HS-SICH timing relationship
| … | Subframe N | Subframe N+1 | Subframe N+2 | Subframe N+3 | Subframe N+4 | Subframe N+5 | … |
| ?E-AGCH | ?HS-SICH |
Perhaps, do not adopt E-AGCH and HS-SICH that timing relationship is set, with HS-SICH timing relationship is set but adopt high speed downlink packet to insert High-Speed Shared Control Channel (HS-SCCH), concrete method to set up is with above-mentioned between E-AGCH and HS-SICH timing relationship to be set identical, and, in order to prevent that the HS-SICH that sends the resource distribution feedback message from clashing, need Node B to guarantee not send simultaneously in the same subframe HS-SCCH and E-AGCH.
Channel is selected 3, is adopted E-RUCCH to send the resource distribution feedback message.
UE by E-RUCCH when Node B sends the resource distribution feedback message, directly utilize the SI on the E-RUCCH to represent this feedback message, the implication in specifying information territory definition identical with described in the above-mentioned employing E-PUCH transmission resource distribution feedback message do not repeat them here.
Adopt above-mentioned resource allocation method, need improve UE and Node B, the composition structure of UE and Node B respectively as shown in Figures 2 and 3 in the embodiment of the invention.
Referring to Fig. 2, the composition structure of UE comprises at least in the embodiment of the invention: receiver module 201, sending module 202 and control module 203.
Referring to Fig. 3, the composition structure of Node B comprises at least in the embodiment of the invention: receiver module 301, sending module 302 and control module 303 further, can also comprise timer 304.
Sending module 302 sends the resource distribution order according to the resource distribution control command of control module 303 to UE.Receiver module 301 receives the resource distribution feedback message that UE sends, and sends it to control module 303.Control module 303 sends the resource distribution control command to sending module 302, controls it and sends the resource distribution order to UE; Control module 303 receives the resource distribution feedback message that UE sends from receiver module 301, judge resource distribution success or failure according to the resource distribution feedback message, if the resource distribution failure sends the resource distribution control command to sending module 302 again, control it and send the resource distribution order to UE.
Further, can also comprise timer 304 among the Node B.Control module 303 is sending enabled instruction to timer 304 when sending module 302 sends the resource distribution control command, timer 304 picks up counting, and timer 304 sends overtime notice to control module 303 when surpassing setting-up time.After control module 303 is received the overtime notice of timer 304 transmissions, send the resource distribution control commands to sending module 302 again, control it and send the resource distribution order to UE.Control module 303 sends out codes to timer 304 after receiving the resource distribution feedback message that UE sends from receiver module 301, and timer 304 cuts out and will have the timing zero clearing now.
By above embodiment as seen, UE configurating channel resource and send the resource distribution feedback message after receiving the resource distribution order that Node B sends to Node B, report resource distribution success or failure by this message to Node B, when Node B does not still receive the resource distribution feedback message in the resource distribution failure or above setting-up time, send the resource distribution order to UE again.Because UE reports Node B with the implementation status of resource distribution, therefore under the situation of resource distribution command transfer mistake, Node B can know in time that channel resource is not configured, thereby resend the resource distribution order, therefore can finish resource distribution accurately, avoided Node B and UE to go up the inconsistent situation of resource allocation status, and then avoid Node B will be as yet the channel resource that disposes of success distribute to the uplink interference that other UE uses and therefore produces once more, also make Node B can be become the resource allocation of the distribution of work to other UE.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
