Embodiment
Fig. 1 is the flow chart of uplink resource allocating method embodiment one of the present invention, as shown in Figure 1, the described method that the present embodiment provides is particularly useful in LTE system, the main thought of the method is: base station is by carrying out periodic statistics to the RB resource using information of user terminal each in its coverage cell, to obtain the up GBR traffic satisfaction rate statistical value of community in this cycle, this statistics comprises the RB resource that priority uses higher than the business of GBR traffic; The satisfaction rate statistical value in an above cycle is reference, determine (the Transmission Time Interval of current transmission time interval in this cycle, hereinafter referred to as TTI) in the Non-GBR business in community of being used in can be divided to use RB number of resources, and as limit, while in current TTI, have the user terminal of GBR traffic and Non-GBR business to dispatch.Whole RB resource carried out the division for GBR traffic and Non-GBR business based on up GBR traffic satisfaction rate statistical value, thus can the RB Resourse Distribute of described two kinds of business be carried out to certain user terminal simultaneously.What deserves to be explained is, the user terminal described in the present embodiment refers in particular to the user terminal simultaneously with GBR traffic and Non-GBR business.But for only having the terminal of Non-GBR business, dispatched owing to having the terminal of GBR traffic prior to only having the terminal of Non-GBR business, when scheduling only has the terminal of Non-GBR business, the GBR traffic of this TTI community has been dispatched complete, the speed of GBR traffic is also guaranteed, now, the remaining RB resource in community is used by Non-GBR business totally, Bu Shou community Non-GBR can the restriction of RB number of resources; Or after there is in community the terminal scheduling of GBR traffic, community Non-GBR business can be updated to community residue RB number of resources by RB number of resources, use for the Non-GBR business in community.
The described method that the present embodiment provides comprises:
Step 101, use information according to each user terminal uploads RB resource, periodically obtain the satisfaction rate statistical value of GBR traffic in community, user's satisfaction rate statistics of described GBR traffic comprises the ratio of the RB total number resource of RB number of resources sum that the GBR traffic of described each user terminal and priority uses higher than the business of described GBR traffic and PUSCH;
In LTE system, by enhanced base station (evolved Node B, hereinafter referred to as eNB), unified resource allocation scheduling is carried out, to realize resource-sharing to the uplink of different user terminals.In LTE system, because GBR traffic has higher dispatching priority than Non-GBR business, therefore, when carrying out Resourse Distribute to user terminal, its GBR traffic Resources allocation is preferably.In the present embodiment, eNB carries out periodic statistics to the satisfaction rate of cell uplink GBR traffic, the satisfaction rate statistical value in an above cycle is as the constraint of next cycle RB Resourse Distribute, but what deserves to be explained is, when system initial launch, eNB can carry out the distribution of up RB resource according to prior art, or can carry out the distribution of up RB resource according to the method that the present embodiment provides according to the satisfaction rate preset.
Particularly, due to the up GBR traffic of LTE system and Non-GBR business row shared channel (Physical Uplink Shared Channel physically, hereinafter referred to as PUSCH) upper transmission, so the satisfaction rate statistical value of GBR traffic in the present embodiment comprises: the ratio of the RB number of resources sum that in this cycle, the GBR traffic of each user terminal and priority use higher than the business of GBR traffic and the RB total number resource of PUSCH.
In addition, what deserves to be explained is why add up the satisfaction rate of up GBR traffic, and using the satisfaction rate of this GBR traffic as the prerequisite of Resourse Distribute, be because the priority of GBR traffic is higher than Non-GBR business, and the guaranteed rate of GBR traffic must be met.
Step 102, satisfaction rate statistical value according to the RB number of resources of the PUSCH of the current TTI of current period and the described GBR traffic in last cycle, determine the assignable resource RB number of Non-GBR business in current TTI, it is positive integer that described current period comprises N number of described TTI, N;
In LTE system, be that minimum time unit is dispatched to the dispatching distribution of RB resource with TTI, base station eNB is responsible for carrying out unified scheduling and management to RB resource, so it can know the RB number of resources of the PUSCH of current TTI, based on the satisfaction rate statistical value in a upper cycle adding up acquisition in this RB number of resources and step 101, the assignable resource RB number of Non-GBR business in community in the current TTI that can obtain current period, wherein, it is positive integer that described current period comprises N number of described TTI, N.
The RB number of resources needed for GBR traffic of active user's terminal and the RB number of resources needed for Non-GBR business in step 103, acquisition current TTI;
After base station eNB receives the resource bid request of multiple user terminal in community in current TTI, eNB can be followed successively by the GBR traffic of each user terminal according to the dispatching priority of each user terminal order and Non-GBR business carries out resource allocation scheduling.Due to similar to the scheduling of each user terminal, only explain for active user's terminal in the present embodiment, this current user terminal is the pending active user's terminal determined according to described dispatching priority.
Particularly, eNB needs to obtain the RB number of resources needed for GBR traffic of active user's terminal and the RB number of resources needed for Non-GBR business in current TTI, specifically, can according to the modulation coding mode of the channel quality of active user's terminal, selection (Modulation and Coding Scheme, hereinafter referred to as MCS) exponent number, the guaranteed rate of GBR and Buffer Status Report (Buffer Status Report, hereinafter referred to as the BSR) message of active user's terminal to report determines GBR traffic and the RB number of resources needed for Non-GBR business.
The RB number of resources that the GBR traffic that step 104, RB number of resources needed for the GBR traffic of described active user's terminal are defined as described active user's terminal is distributed;
Step 105, RB number of resources needed for the Non-GBR business of Non-GBR business assignable RB number of resources and described active user's terminal in described current TTI are defined as the RB number of resources of the Non-GBR traffic assignments of described active user's terminal;
Step 106, by the GBR traffic RB resource distributing to described active user's terminal of quantification and Non-GBR business RB resource, by CCE resource authorization give described active user's terminal.
In the present embodiment, when eNB knows the RB number of resources needed for active user's terminal GBR traffic and the RB number of resources needed for Non-GBR business in current TTI, and in current TTI in community after the assignable resource RB number of Non-GBR business, can the RB number of resources needed for active user's terminal GBR traffic be that the GBR traffic of active user's terminal carries out RB Resourse Distribute, RB number of resources simultaneously needed for Non-GBR business assignable resource RB number in community in current TTI and active user terminal Non-GBR business is that the Non-GBR business of described active user's terminal carries out RB Resourse Distribute, and then the RB resource of will distribute, this current user terminal is given by CCE resource authorization.
What deserves to be explained is, because the priority of GBR traffic is higher than Non-GBR business, and the guaranteed rate of GBR traffic must be met, therefore, the RB number of resources that the GBR traffic that RB number of resources in the present embodiment needed for active user's terminal GBR traffic is defined as described active user's terminal is distributed, the GBR traffic be as active user's terminal distributes the number of resources of the RB needed for its reality.In addition, the assignable RB number of resources of Non-GBR business is removed in RB number of resources due to the PUSCH of current TTI, remaining RB resource is namely for the scheduling of GBR traffic in community, therefore, if active user's terminal GBR traffic need RB number of resources more than GBR traffic in current TTI community can RB total number resource, the demand of active user's terminal GBR traffic so now can be met by taking the assignable RB number of resources of Non-GBR business, that is, now can reduce the assignable RB number of resources of Non-GBR business in current TTI community, the demand of GBR traffic is met by the assignable RB number of resources of adjustment Non-GBR business.
In the present embodiment, the satisfaction rate statistical value of up GBR traffic is obtained according to the use information of user terminal uploads RB resource each in community, thus obtain the assignable RB number of resources of current TTI Zhong Gai community Non-GBR business based on this satisfaction rate statistics, and then get the GBR traffic of each user terminal and Non-GBR business respectively needed for RB number of resources after, determine that actual is each user terminal distribution Non-GBR business RB resource according to Non-GBR business assignable RB number of resources in current TTI Zhong Gai community, in conjunction with the RB number of resources that the GBR traffic of this user needs, by the GBR traffic of same user terminal determined and the RB resource of Non-GBR traffic assignments, by this user terminal of CCE resource authorization.By the RB resource of PUSCH being carried out the division for GBR traffic and Non-GBR business, and determine based on the satisfaction rate statistics of up GBR traffic the RB total number resource that Non-GBR business can be distributed in current TTI, when coming to dispatch the terminal simultaneously having GBR traffic and Non-GBR business in current TTI as restriction, the RB number of resources that its Non-GBR business is distributed, ensure that enough RB resources that has of the GBR traffic of the family terminal of its follow-up scheduling can be used, guarantee the service quality of the GBR traffic of all users, simultaneously for having GBR traffic and Non-GBR service-user terminal simultaneously, only need once to eat dishes without rice or wine to authorize, improve the dispatching efficiency of resource, save CCE resource.
Fig. 2 is the flow chart of uplink resource allocating method embodiment two of the present invention, and as shown in Figure 2, the method comprises:
Step 201, use information according to the RB resource of each user terminal uploads, periodically obtain the satisfaction rate statistical value of GBR traffic in community, the satisfaction rate statistical value of described GBR traffic comprises the ratio of the RB total number resource of RB number of resources sum that the GBR traffic of described each user terminal and priority uses higher than the business of described GBR traffic and PUSCH;
Step 202, with the RB number of resources of the PUSCH of described current TTI, be multiplied by the satisfaction rate statistical value of described GBR traffic, obtain the RB number of resources that in current TTI, GBR traffic needs, with the RB number of resources of the PUSCH of described current TTI, deduct the RB number of resources that described GBR traffic needs, obtain the assignable resource RB number of Non-GBR business in current TTI;
Particularly, in the present embodiment, due to the service quality QoS grade according to business in LTE system, main is GBR traffic and Non-GBR business by delineation of activities, therefore, ideally, base station can to obtain in current TTI the assignable resource RB number of Non-GBR business in community by following mode:
With the RB number of resources of the PUSCH of described current TTI, be multiplied by the satisfaction rate statistical value of described GBR traffic, obtain the RB number of resources that in current TTI, GBR traffic needs;
With the RB number of resources of the PUSCH of described current TTI, deduct the RB number of resources that described GBR traffic needs, obtain the assignable resource RB number of Non-GBR business in current TTI.
Therefore, in the present embodiment, the RB number of resources that the GBR traffic of all user terminals in current period current TTI in community needs to use and the Non-GBR business operable RB number of resources upper limit can be determined according to the satisfaction rate statistics of up GBR traffic, and on this basis resource allocation scheduling be carried out to each user terminal in current TTI.
The channel quality that step 203, basis are corresponding with described active user's terminal, determines the MCS exponent number corresponding with described active user's terminal;
Step 204, according to the guaranteed rate of the GBR traffic of the MCS exponent number determined, described active user's terminal and the BSR information of described active user's terminal to report, obtain the RB number of resources needed for GBR traffic of described active user's terminal, described BSR message comprises the data to be transferred amount information of described GBR traffic;
Step 205, according to described MCS exponent number and described BSR message, obtain the RB number of resources needed for Non-GBR business of described active user's terminal, in described BSR message, also comprise the data to be transferred amount information of described Non-GBR business;
Particularly, know all user terminals in current TTI Non-GBR business can RB number of resources after, base station eNB need obtain the RB number of resources needed for the actual application of the user terminal of current scheduling.Wherein, eNB is according to the channel quality of described active user's terminal, the MCS exponent number that selected described active user's terminal is corresponding, according to the guaranteed rate of the GBR traffic of the MCS exponent number determined, described active user's terminal and the BSR information carrying the data to be transferred amount information of GBR traffic of described active user's terminal to report, the RB number of resources needed for GBR traffic of described active user's terminal can be obtained; According to the MCS exponent number determined and the above-mentioned BSR information of data to be transferred amount information carrying Non-GBR business, obtain the RB number of resources needed for Non-GBR business of described active user's terminal, this part is prior art, repeats no more.
The RB number of resources of RB number of resources needed for the GBR traffic of described active user's terminal that step 206, the GBR traffic being defined as described active user's terminal are distributed;
Step 207, judge in described current TTI, whether Non-GBR business assignable RB number of resources is more than or equal to the RB number of resources needed for Non-GBR business of described active user's terminal, if be more than or equal to, then perform step 208; Otherwise, if be less than, then perform step 209;
Step 208, be defined as the RB number of resources of RB number of resources needed for the Non-GBR business of described active user's terminal of the Non-GBR traffic assignments of described active user's terminal;
Step 209, the RB number of resources being defined as the Non-GBR traffic assignments of described active user's terminal are the assignable RB number of resources of Non-GBR business in described current TTI;
Step 210, with described Non-GBR business assignable RB number of resources be the difference of RB number of resources of Non-GBR traffic assignments of described active user's terminal, upgrade the assignable RB number of resources of Non-GBR business in described current TTI;
Step 211, by the GBR traffic RB resource distributing to described active user's terminal of quantification and Non-GBR business RB resource, by CCE resource authorization give described active user's terminal.
When after the RB number of resources needed for the GBR traffic reality that eNB has known active user's terminal and the RB number of resources needed for Non-GBR business reality, need with the actual assignable RB number of resources in the community determined for certificate, the final RB resource being this current user terminal and determining to distribute.
Particularly, because the priority of GBR traffic is higher than Non-GBR business, and the guaranteed rate of GBR traffic must be met, the RB number of resources of RB number of resources needed for the GBR traffic of described active user's terminal that the GBR traffic being therefore defined as described active user's terminal is distributed.
In actual applications, by reasonably selecting the measurement period of the satisfaction rate of up GBR traffic, the RB number of resources that in the current TTI obtained based on the satisfaction rate statistical value of up GBR traffic, GBR traffic needs the change of the statistical property of business in community between adjacent periods can be made little, so can ensure the demand of the GBR traffic of all user terminals.But, if the RB number of resources that active user's terminal GBR traffic needs is greater than the RB number of resources of GBR traffic needs in current TTI, now illustrate that the RB number of resources for GBR traffic in current TTI community is not enough to the actual demand meeting active user's terminal, then can by adjustment current TTI community in Non-GBR business can RB number of resources, even if it is less than the RB number of resources calculated according to the satisfaction rate statistical value of up GBR traffic, thus certain RB resource is shifted out for GBR traffic.
When carrying out RB Resourse Distribute to the Non-GBR business of active user's terminal, first base station eNB will judge in current TTI, whether the assignable RB number of resources of Non-GBR business is more than or equal to the RB number of resources needed for Non-GBR business of active user's terminal, if be more than or equal to, be then defined as the RB number of resources of RB number of resources needed for the Non-GBR business of described active user's terminal of the Non-GBR traffic assignments of described active user's terminal; If be less than, then the RB number of resources being defined as the Non-GBR traffic assignments of described active user's terminal is the assignable RB number of resources of Non-GBR business in described current TTI.Because Non-GBR business is without the need to carrying out meeting of guaranteed rate, therefore, when Non-GBR business assignable RB number of resources is less than this current user terminal actual needs, the Non-GBR business that these assignable RB number of resources all distribute to this current user terminal is used.Afterwards, upgrade the assignable RB number of resources of described Non-GBR business, namely the RB number of resources that the Non-GBR business deducting described active user's terminal is distributed, using the assignable RB number of resources after upgrading as the foundation of the Non-GBR business RB Resourse Distribute of the pending user terminal of the next one.What deserves to be explained is, if community current residual RB number of resources is less than the RB number of resources needed for active user's terminal, Ze Jiang community residue RB resource all distributes to this terminal, and these RB resource priority are for sending the data of GBR traffic.Finally, base station eNB, by the GBR traffic RB resource distributing to described active user's terminal of quantification and Non-GBR business RB resource, gives described active user's terminal by CCE resource authorization.
In the present embodiment, the Non-GBR business operable RB number of resources upper limit of all user terminals in current period current TTI in community is determined according to the satisfaction rate statistical value of up GBR traffic, and on this basis resource allocation scheduling is carried out to each user terminal in current TTI, because satisfaction rate statistics is what to obtain based on the GBR traffic of having met consumers' demand, the QoS requirement of the GBR traffic of user terminal therefore effectively can be ensured; Simultaneously for the GBR traffic of user terminal and Non-GBR business carry out the allocation schedule of RB resource, decrease scheduling times, improve dispatching efficiency, saved CCE resource.
