The resource allocation method provided by the invention comprises the following steps of: determining user equipment UE to be allocated with the dedicated scheduling request D-SR resource; determining a D-SR resource allocation priority queue consisting of the UE according to a preset priority order; and allocating the preset D-SR resource to the UE in the D-SR resource allocation priority queue according to the priority order.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of resource allocation methods and device.
Background technology
Long Term Evolution (LTE) system is a communication system based on scheduling; If there are data to need to send in the transmission buffer memory of subscriber equipment (UE); UE needs to send a buffer status report (BSR for earlier evolved base station (eNB) so; Buffer status report), notify the data message that needs transmission in the current transmission buffer memory of eNB UE.ENB comes for UE distributes corresponding Uplink Shared Channel (UL-SCH) resource according to the data volume that the UE needs send after receiving the BSR that UE sends, and notice UE sends data on the UL-SCH resource of distributing.
UE sends BSR to eNB also need use the UL-SCH resource; If UE has BSR to report, but do not have UL-SCH resource this moment, will send dispatch request (SR to eNB so for self distribution; Scheduling Request), request eNB distributes the UL-SCH resource for the BSR that needs to send.
The mode that UE sends SR has two kinds: a kind of for sending SR through specific schedule request resource (D-SR resource); Another kind of for to send SR through random access procedure.
When UE and eNB are in synchronous regime, the D-SR resource is not necessarily arranged, when UE and eNB are in asynchronous regime, necessarily there is not the D-SR resource.So-called D-SR resource, the resource that promptly is used for sending D-SR.
The basic principle that UE sends SR is: as long as there is the D-SR resource, just do not send SR through random access procedure.
UE sends the time restriction of SR: receive eNB be UE being used to of distributing send the UL-SCH resource of data before, can on the resource that can send SR, repeat to send SR.
In the LTE system, the D-SR resource is carried by Physical Uplink Control Channel (PUCCH) by the configuration of Radio Resource control (RRC) layer, i.e. the up specific schedule request SR of UE transmission transmits on PUCCH, adopts the form 1/1a/1b (being format1/1a/1b) of PUCCH.
For PUCCH format1/1a/1b; Symbol and length are that 12 cyclically shifted sequences multiplies each other and carries out frequency domain expansion; Formation length is 12 symbol sebolic addressing; Be that 4 orthogonal sequence multiplies each other and carries out the time domain expansion with this symbol sebolic addressing and length then, and be mapped on 12 * 4 time-frequency positions of corresponding Physical Resource Block on the time slot (PRB, physical resource block) (having 3 symbols to be used to transmit SR).
Yet, also do not provide the technical scheme how network side gives the D-SR resource allocation UE in the prior art, so UE can't obtain the D-SR resource, that is to say that network side also can't be embodied as UE and distribute the D-SR resource.

D-SR resource allocation unit 113 is used for according to priority orders, gives the UE 12 among the D-SR priority of resource allocation formation Q with pre-configured D-SR resource allocation.
Said priority orders is:
The order from small to large of priority (priority) property value of the pairing label of radio bearer (RB) (Label characteristics) of UE 12 request D-SR resources; Perhaps,
Packet loss budget (PDB, packet delay budget) the property value order from small to large of the pairing label of radio bearer (Label characteristics) of UE 12 request D-SR resources; Perhaps,
The time order and function order that the radio bearer of UE12 request D-SR resource is set up.
Preferably; Said D-SR resource allocation unit 113; According to the time order and function order of SR all uplink conventional subframe in the cycle, and priority orders, the UE 12 among the D-SR priority of resource allocation formation Q given with the D-SR resource allocation in each uplink conventional subframe successively.
Particularly; D-SR resource allocation unit 113, according to the SR cycle, to a SR in the cycle all uplink conventional subframe according to the ordering of the sequencing of time; And from high to low according to the priority of UE in the formation of SR priority of resource allocation; Be followed successively by UE and distribute the D-SR resource in the uplink conventional subframe, the D-SR resource of a uplink conventional subframe uses up, and then continues to distribute the D-SR resource of next uplink conventional subframe; The D-SR resource of all UE in formation Q distributes, till perhaps the D-SR resource of interior all uplink conventional subframe of SR cycle has distributed.The pairing time of D-SR resource that UE obtained that priority is high more is forward more.
Preferably, said queued units 112 comprises:
First queued units 21 is used for confirming the D-SR priority of resource allocation formation that is made up of said UE 12 according to the priority orders that is provided with in advance.

Wherein, satisfy the UE of preset distributive condition, for example: the UE that is in synchronous regime; Perhaps, be in synchronous regime, and be in the UE of non-long DRX state.
Preferably, said definite unit 111, when system loading during less than preset threshold value, the UE 12 that will be in synchronous regime confirms as the UE 12 of D-SR resource to be allocated; Perhaps,, will be in synchronous regime, and the UE 12 that is in non-long DRX state confirms as the UE 12 of D-SR resource to be allocated when system loading during greater than preset threshold value.
D-SR resource allocation unit 113; When the UE that is assigned to the D-SR resource gets into desynchronizing state or long DRX state, discharge the D-SR resource of this UE, and by preset priority orders; From formation QW, get the highest UE of priority, give this UE this D-SR resource allocation.
The base station needed configuration D-SR resource earlier before distributing the D-SR resource for UE, promptly confirm the D-SR stock number, provided the concrete scheme explanation of how to dispose the D-SR resource in the embodiment of the invention below.
System can reserve the specific schedule request resource of a part of PUCCH resource as the sub-district, i.e. D-SR resource, and this resource size can be given each UE through broadcast broadcast announcement in the sub-district.The embodiment of the invention is to the D-SR resource; Provided a kind of semi-static allocation plan; The D-SR stock number of sub-district is confirmed in realization from the PUCCH resource of reserving, confirm that just the interior PUCCH channel of each uplink conventional subframe in each SR cycle can carry the D-SR of what UE.
Because the D-SR resource belongs to cell-level D-SR resource, so configuration D-SR resource in the embodiment of the invention, in fact be exactly the D-SR stock number of confirming the sub-district.
In the embodiment of the invention, the equipping rules of cell-level D-SR resource is to guarantee that the D-SR resource satisfies under the situation of UE demand in the sub-district, reduces taking the PUCCH resource as far as possible.
The configuration of cell-level D-SR resource is mainly considered to be in the configuration information, SR cycle, sub-district of up link (the UL)/up link (DL) of sub-district the quantity of the UE of synchronous regime further to it is also conceivable that the activation degree that each UE is professional.
Wherein, the professional activation degree of UE can be distinguished through the DRX state, to being in the UE of long DRX state, can think that the activation degree is not high, can not be thought of as this UE configuration D-SR resource.
That is to say, preferably, be in the UE of synchronous non-long DRX state in the embodiment of the invention in the main consideration sub-district, do not consider to be in the UE of desynchronizing state and long DRX state.
In the embodiment of the invention, semi-static configuration mode is adopted in the configuration of sub-district D-SR resource, and semi-static layoutprocedure comprises pre-configured process and dynamic adjustment process.Pre-configured process is mainly accomplished the initial configuration of sub-district D-SR resource; Dynamic adjustment process promptly according to the system loading situation, is adjusted the size or the cycle of sub-district D-SR resource, to improve the utilance of PUCCH resource.
Provide the detailed introduction of pre-configured process and dynamic adjustment process below.
The pre-configured process of cell-level D-SR resource comprises:
Step 1: the quantity usernum_per_PRB that confirms the UE that a PRB can carry according to the cyclic shift interval deltashift of the selected cyclically shifted sequences of RRC:
usernum_per_PRB＝cycshiftseq_len/deltashift*oth_num
Wherein,
Cycshiftseq_len is the length of cyclically shifted sequences, for PUCCH channel, cycshiftseq_len=12.
Deltashift is the cyclic shift interval of cyclically shifted sequences, the value of deltashift can for: 1,2 or 3, generally speaking; Deltashift=2 if the quantity of UE is many, can be provided with deltashift=1; That is to say that the quantity of UE is many more, the value of deltashift is more little.
Oth_num is the number of orthogonal sequence, for PUCCH (1) channel, i.e. and the PUCCH channel of form 1, oth_num=3.
Same PRB goes up the different UEs of carrying, and distinguishes through different cyclic shift value.
Step 2:, confirm that a length is the number M of the uplink conventional subframe in the radio frames of 10 milliseconds (ms) (radio frame) according to the configuration information of UL/DL.
At present in the LTE system just like the configuration of several kinds of UL/DL shown in the following table one:
Table one
Wherein 0 to 9 representes subframe numbers, and D represents descending time slot, and S represents special time slot, and U represents ascending time slot.
Step 3: statistical system is in preset time period T; Be in synchronous regime in all uplink conventional subframe, set up radio bearer (RB); And be in the quantity of the UE of non-long DRX state; And all uplink conventional subframe in the time period T are averaged, obtain the par UE_NUM_AVG that each uplink conventional subframe is in the UE of synchronous non-long DRX state.
Step 4:, select a suitable SR cycle PERIOD the cycle from preset a plurality of SR according to the number M of uplink conventional subframe in the radio frame who confirms in UE_NUM_AVG and the step 2.
The SR cycle of supporting at present is divided into five kinds of 5ms, 10ms, 20ms, 40ms, 80ms.What is called is selected a suitable SR cycle PERIOD from preset a plurality of SR the cycle, promptly the cycle, confirm the SR cycle PERIOD of a SR cycle as current employing from preset a plurality of SR according to system loading.For example: if the uplink conventional subframe number that system loading is very heavy and each raido frame is interior seldom, then can select the relatively long SR cycle for use, otherwise can select relatively than the short SR cycle.
Said system loading, the number of the UE that can insert for current system.For example, the number of the UE that inserts when system surpasses predefined threshold value, and the uplink conventional subframe number in each radio frames can be selected the SR cycle PERIOD of 40ms as current employing when being less than certain value.
Certainly, according to actual needs, can preset the different threshold value, and confirm the different SR cycles to system loading.
Step 5: the conventional number of sub-frames NUM in the definite SR cycle; And this three partial content of average UE_NUM_AVG of the quantity of the UE that supports of the quantity usernum_per_PRB of the UE that can support according to NUM, each PRB, each uplink conventional subframe needs; Calculate the D-SR resource that disposes for UE in each subframe; Each uplink conventional subframe of promptly confirming each SR cycle in the current PUCCH channel resource can be carried the SR of what UE of this sub-district, if use N
PUCCH (1), SRThe quantity of representing the UE that each uplink conventional subframe in each SR cycle in the current PUCCH channel resource can be carried, then:
Wherein, ceil representes to round.
Certainly, can be known by following formula, not adopt the usernum_per_PRB parameter, also be can be in the hope of N and directly adopt UE_NUM_AVG and these two parameters of NUM
PUCCH (1), SR.
N
PUCCH (1), SRValue be the value of D-SR stock number of each uplink conventional subframe in each SR cycle.
The dynamic adjustment process of D-SR resource comprises:
Because the cell-level parameter is transmitted through broadcast; Therefore unsuitable frequent variations can adopt periodically or the adjustment strategy of set time section, that is to say; The dynamic adjustment process of D-SR resource can be according to predetermined period; Cycle carries out, and also can be according to the Preset Time section, when this time period arrives, regularly carries out.Specifically scheme is for example:
Steps A: the execution cycle of dynamic adjustment is set in advance, for example every at a distance from some days the dynamic D-SR resource in time period T of adjustment (T can be unit with the some hrs).
Step B: the D-SR resource (D-SR of first resource) of distributing in the last time period T of statistics; And last satisfy distributive condition but do not obtain the needed D-SR resource of UE (second portion D-SR resource) of D-SR resource, and calculate the average of the D-SR of first resource and second portion D-SR resource.
Wherein, The so-called last time satisfies distributive condition but does not obtain the size of the needed D-SR resource of UE of D-SR resource, promptly in the assigning process of last once D-SR resource, because cell-specific D-SR is resource-constrained; The UE that might not allly be in synchronous and non-long DRX state can both be assigned to the D-SR resource; Have a part of UE and do not obtain the D-SR resource, therefore current in the process of adjustment D-SR resource, need consider the size of the D-SR resource that this a part of UE need obtain.
Step C: the average of utilizing step B to obtain, confirm the size or the SR cycle of the D-SR resource in the current slot T.
For example: if the twice of the size of the D-SR resource of configuration in the current slot T that the average of step B statistics is step C to be confirmed then can be adjusted into the SR cycle twice in current definite SR cycle; Perhaps, keep the last SR cycle of confirming constant, just the SR resource of each uplink conventional subframe of last time configuration is adjusted into the twice of SR resource of each uplink conventional subframe of current configuration, can more effectively use the PUCCH resource like this.
To sum up, definite method of a kind of D-SR resource of providing of the embodiment of the invention comprises step: the number average value UE_NUM_AVG that confirms to be in each uplink conventional subframe in the Preset Time section T UE of synchronous regime.And,, confirm the uplink conventional subframe number NUM in each SR cycle according to the configuration information of up link or down link.Utilize UE_NUM_AVG and NUM, confirm the quantitative value of the UE that PUCCH can carry in each uplink conventional subframe, with the value of this value as the D-SR stock number in each uplink conventional subframe in each SR cycle.
Preferably, definite method of this D-SR resource also comprises: the quantity usernum_per_PRB that confirms the UE that each PRB can carry.
Preferably, utilize usernum_per_PRB, NUM and UE_NUM_AVG, confirm the value of the D-SR stock number in each uplink conventional subframe in each SR cycle.
