The embodiment of the present invention one provides a kind of shared channel resources distribution method based on multicarrier system, and the method can be distributed for the resource of up link, also can distribute for the resource of down link.In the shared channel resources distribution method that the embodiment of the present invention proposes, according to the QoS of survice requirement of each subscriber equipment in preferential guarantee system, secondly the scheduling process of each subframe is divided into N wheel by the thought of promoting transmission rate as far as possible, front M(M<=N) wheel scheduling is used for ensureing QoS of survice requirement, the scheduling of rear N-M wheel is for promoting transmission rate; And take turns in scheduling process every, each carrier wave adopts the mode of distributed scheduling, carries out respectively shared channel resources distribution.As shown in Figure 1, the method comprises the following steps:

Step 101, network side is that current subscriber equipment to be scheduled carries out carrier wave selection (be current subscriber equipment to be scheduled and select one or more suitable carrier waves) according to specifying scheduling strategy; Wherein, this appointment scheduling strategy is specially the requirement of preferential guarantee QoS of survice, secondly promoting transmission rate.

Step 102, network side is assigned to the business datum to be transmitted of subscriber equipment on the carrier wave of selection.

Step 103, network side is on the carrier wave of each selection, distribute the shared channel resources assigning process in the mode completion system (being multicarrier system) of i.e. network side employing distributed scheduling on all carrier waves according to the business datum difference executed in parallel shared channel resources to be transmitted of the carrier wave of distributing to each selection.

In the embodiment of the present invention, carrier wave selection course can be used as subscriber equipment, and business datum to be transmitted is some part according to being divided into someway, is assigned on some carrier waves, and the resource participating on some carrier waves so that parallel is distributed and transfer of data; In the time that many wheels are carried out in scheduling, every wheel all can be carried out primary carrier selection course in scheduling.As shown in Figure 2, be the flow chart of distributed many wheel scheduling schemes, n represents the carrier number in system.

In the embodiment of the present invention, network side according to specify scheduling strategy be current subscriber equipment to be scheduled carry out carrier wave select comprise: network side is in epicycle scheduling process, if epicycle is scheduling to first round scheduling, based on ensureing that the scheduling strategy that QoS of survice requires (QoS of survice that ensures each subscriber equipment in system requires) carries out carrier wave selection for current subscriber equipment to be scheduled; If epicycle scheduling is not first round scheduling, the residue that meets situation, the subscriber equipment business datum the amount to be transmitted band resource on each carrier wave in system, QoS of survice being required checks; If the band resource in system on all carrier waves is assigned (being all there is no remaining available resource on all carrier waves in system) and/or remains business datum amount to be transmitted for empty (being that the business datum whole to be transmitted for the treatment of scheduling user's set in system has all been distributed transfer resource), the shared channel resources assigning process of determining current subframe finishes, i.e. the scheduling process of the current subframe of premature termination; Otherwise if the QoS of survice of the scheduling user's set that needs requires all to have met in system, the scheduling strategy based on promoting transmission rate (as far as possible promoting transmission rate) carries out carrier wave selection for current subscriber equipment to be scheduled; If the QoS of survice of the scheduling user's set that needs requires all not meet in system, based on ensureing that the scheduling strategy that QoS of survice requires (QoS of survice that ensures each subscriber equipment in system requires) carries out carrier wave selection for current subscriber equipment to be scheduled.

In the embodiment of the present invention, network side is that current subscriber equipment to be scheduled carries out carrier wave and selects to comprise according to specifying scheduling strategy: when epicycle is scheduling to when scheduling first round, network side is that the carrier wave that current subscriber equipment to be scheduled is selected is the main carrier that subscriber equipment is corresponding.

Concrete, because the channel quality of subscriber equipment on main carrier is best, the carrier wave selection course of therefore dispatching in the first round, each subscriber equipment can be chosen in and on main carrier, participate in resource and distribute, and network side is all assigned to the business datum to be transmitted of each subscriber equipment on the main carrier of this subscriber equipment and dispatches.

In the embodiment of the present invention, when epicycle is scheduling to when scheduling first round, network side, based on ensureing that the scheduling strategy that QoS of survice requires is that current subscriber equipment to be scheduled carries out carrier wave selection, specifically comprises:

Step 1, network side are that the carrier wave that current each subscriber equipment to be scheduled is selected is the main carrier that each subscriber equipment is corresponding; Concrete, each subscriber equipment is chosen in and on main carrier, participates in resource and distribute, and network side is all assigned to the business datum to be transmitted of each subscriber equipment on the main carrier of subscriber equipment and dispatches.

Step 2, on the carrier wave that the business datum to be transmitted of subscriber equipment is assigned to selection after, network side is being on the carrier wave selected of each subscriber equipment, calculates respectively to meet the needed PRB of whole business datums to be transmitted and count PRB _c, according to the traffic assignments situation of step 1, each carrier wave calculates respectively and meets the needed PRB of whole transmission demands and count PRB _c; Wherein, subscript c represents carrier wave.

In the embodiment of the present invention, the PRB that network side calculates carrier wave c counts PRB _cprocess, further comprise: for the business datum to be transmitted being assigned on carrier wave c, the qos parameter of each business that network side comprises according to subscriber equipment, is met the data volume DATA of the required transmission of each QoS of survice requirement _qoS(i); Network side is according to the broadband CQI(Channel Quality Indicator of user equipment to report, channel quality instruction) DATA of information and each business _qoS(i), be met the needed PRB of each QoS of survice requirement and count PRB _qoS(i); Network side is according to the PRB of all subscriber equipmenies _qoS(i) PRB that calculates carrier wave c counts PRB _c.

Concrete, for the subscriber equipment being assigned on this carrier wave c, the qos parameter of each business that network side comprises according to subscriber equipment, as GBR(Guarantee Bit Rate, ensure bit rate), PBR(Prioritised Bit Rate, preferential bit rate) etc., be met the data volume DATA of the required transmission of each QoS of survice requirement _qoS(i); Afterwards, network side is according to the broadband CQI information of user equipment to report and the DATA of each business _qoS(i), be met the needed PRB of each QoS of survice requirement and count PRB _qoS(i), by the PRB of each business of all subscriber equipmenies in system _qoS(i) adding up is exactly PRB _c.

Step 3, when there being PRB _c>pRB _{c_total}carrier wave time, network side travels through the business datum to be transmitted of subscriber equipment on these carrier waves, attempt the business datum all or part of to be transmitted of subscriber equipment is assigned on other carrier wave, until meet PRB _c<=pRB _{c_total}, or on these carrier waves, the business datum to be transmitted of all subscriber equipmenies completes traversal; Wherein, PRB _{c_total}for the available PRB sum of each carrier wave.

Concrete, suppose that the available PRB of each carrier wave adds up to PRB _{c_total}, when there being PRB _c>pRB _{c_total}carrier wave time, illustrate that on these carrier waves, load is overweight, cannot meet the QoS of survice requirement of all subscriber equipmenies, the business datum all or part of to be transmitted of certain customers' equipment need to be assigned on other carrier wave; By traveling through the business of all subscriber equipmenies on these carrier waves, attempt being assigned on other carrier wave, until meet PRB _c<=pRB _{c_total}, or all business on these carrier waves all complete traversal; When there not being PRB _c>pRB _{c_total}carrier wave time, without any operation.

In the embodiment of the present invention, network side attempts the business datum all or part of to be transmitted of subscriber equipment to be assigned on other carrier wave, comprise: network side sorts to the optional carrier wave of business, the optional carrier wave of this business is to meet PRB in the carrier wave having activated of this business home subscriber equipment _c<pRB _{c_total}carrier wave; Network side is carried out following operation successively according to the order sequencing on the optional carrier wave of each business: when calculating this business and transmitting on current carrier wave, meet the needed PRB of QoS of survice requirement and count PRB _qoSif the PRB of the upper existing subscriber's hold facility of the current carrier wave c1 traversing adds up to PRB _c1, PRB _c1+pRB _qoS<=pRB _{c1_total}, attempt being allocated successfully, this traffic assignments is upper to the current carrier wave c1 traversing, and upgrade the occupied PRB sum PRB on carrier wave c1 _c1=pRB _c1+pRB _qoS, upgrade the occupied PRB sum PRB on the primary carrier c0 of this business _c0=pRB _c0-pRB _qoS; If PRB _c1+pRB _qoS>pRB _{c1_total}, can not be assigned on current carrier wave, continue the optional carrier wave of the next business of traversal; Still do not find the carrier wave that can hold this business if traveled through the optional carrier wave of all business, this business attempts being assigned to other carrier wave failure, is still retained in primary carrier and participates in dispatching.
