As shown in fig. 1, the method comprises the steps of:
In the embodiment of the invention, the carrier selection process can be used as user equipment to divide the service data to be transmitted into a plurality of parts according to a certain method, and the parts are distributed to a plurality of carriers so as to participate in resource distribution and data transmission on the plurality of carriers in parallel; when the scheduling is performed for multiple rounds, the carrier selection process is performed once in each round of scheduling.

In the embodiment of the present invention, the carrier selection, performed by the network side for the current user equipment to be scheduled according to the specified scheduling policy, includes: in the current scheduling process, if the current scheduling is the first scheduling, the network side selects the carrier for the current user equipment to be scheduled based on the scheduling strategy for ensuring the service QoS requirement (namely ensuring the service QoS requirement of each user equipment in the system); if the scheduling of the current round is not the first round, checking frequency band resources on each carrier in the system, the meeting condition of service QoS requirements and the remaining service data volume to be transmitted of the user equipment; if the frequency band resources on all carriers in the system are completely allocated (namely, no available resources remain on all carriers in the system) and/or the amount of the remaining service data to be transmitted is empty (namely, all the service data to be transmitted of the user equipment to be scheduled in the system are allocated with transmission resources), determining that the shared channel resource allocation process of the current subframe is finished, namely, terminating the scheduling process of the current subframe in advance; otherwise, if the service QoS requirements of all the user equipment to be scheduled in the system are met, selecting the carrier for the current user equipment to be scheduled based on a scheduling strategy for increasing the transmission rate (i.e. increasing the transmission rate as much as possible); and if the service QoS requirements of all the user equipment to be scheduled in the system are not completely met, carrying out carrier selection for the current user equipment to be scheduled based on a scheduling strategy (namely, the service QoS requirements of all the user equipment in the system are ensured) for ensuring the service QoS requirements.
In the embodiment of the present invention, the carrier selection, performed by the network side for the current user equipment to be scheduled according to the specified scheduling policy, includes: when the current scheduling is the first scheduling, the carrier selected by the network side for the user equipment to be currently scheduled is the main carrier corresponding to the user equipment.
Specifically, since the channel quality of the ue on the primary carrier is the best, in the first round of carrier selection process, each ue can choose to participate in resource allocation on the primary carrier, that is, the network side allocates all the service data to be transmitted of each ue to the primary carrier of the ue for scheduling.
In the embodiment of the present invention, when the current round of scheduling is the first round of scheduling, the network side performs carrier selection for the current user equipment to be scheduled based on the scheduling policy for guaranteeing the QoS requirement of the service, which specifically includes:
step 1, a carrier selected by a network side for each user equipment to be scheduled at present is a main carrier corresponding to each user equipment; specifically, each user equipment selects to participate in resource allocation on the primary carrier, that is, the network side allocates all the service data to be transmitted of each user equipment to the primary carrier of the user equipment for scheduling.
Step 2, after distributing the service data to be transmitted of the user equipment to the selected carriers, the network side respectively calculates the PRB number PRB required by all the service data to be transmitted on the carriers selected for each user equipmentcThat is, according to the service allocation condition in step 1, each carrier calculates the number of PRBs needed to satisfy all the transmission requirementsc(ii) a Where subscript c denotes a carrier.
In the embodiment of the invention, the network side calculates the PRB number PRB of the carrier ccFurther comprising: for the service DATA to be transmitted distributed on the carrier c, the network side obtains the DATA volume DATA required to be transmitted and meeting the QoS requirement of each service according to the QoS parameters of each service contained in the user equipmentQoS(i) (ii) a The network side is set according to the userReporting wideband CQI (Channel Quality Indicator) information and DATA (DATA for each service)QoS(i) Obtaining the PRB number required by meeting the QoS requirement of each serviceQoS(i) (ii) a The network side according to PRB of all user equipmentQoS(i) Calculating PRB number PRB of carrier cc。
Specifically, for the ue allocated to the carrier c, the network side obtains the DATA amount DATA needed to be transmitted to satisfy the QoS requirement of each service according to the QoS parameters of each service included in the ue, such as GBR (guaranteed Bit Rate), PBR (prioritized Bit Rate), and the likeQoS(i) (ii) a Then, the network side reports the wideband CQI information and the DATA of each service according to the user equipmentQoS(i) Obtaining the PRB number required by meeting the QoS requirement of each serviceQoS(i) I.e. PRB of each service of all user equipments in the systemQoS(i) Taken together are the PRBc。
Step 3, when PRB existsc>PRBc_totalWhen the carrier is used, the network side traverses the service data to be transmitted of the user equipment on the carriers, tries to distribute all or part of the service data to be transmitted of the user equipment to other carriers until PRB is metc<=PRBc_totalOr the service data to be transmitted of all the user equipment on the carriers are traversed; wherein PRBc_totalIs the total number of available PRBs for each carrier.
Specifically, assume that the total number of available PRBs for each carrier is PRBsc_totalWhen PRB existsc>PRBc_totalWhen the carriers are used, it is indicated that the carriers are overloaded and cannot meet the service QoS requirements of all the user equipment, and all or part of service data to be transmitted of part of the user equipment needs to be distributed to other carriers; by traversing the traffic of all user equipments on these carriers, it is attempted to allocate them to other carriers until the PRB is fulfilledc<=PRBc_totalOr all the services on the carriers complete traversal; when no PRB existsc>PRBc_totalAnd (3) no operation is required.
In the embodiment of the present invention, a network side attempts to allocate all or part of service data to be transmitted of a user equipment to other carriers, including: sequencing the carriers selectable by the service at the network side, wherein the carriers selectable by the service meet PRB (physical resource block) in the activated carriers of the user equipment to which the service belongsc<PRBc_totalThe carrier wave of (2); the network side sequentially executes the following operations on the carriers selectable by each service according to the ordered sequence: calculating the PRB number required by meeting the QoS requirement of the service when the service is transmitted on the current carrierQoSIf the total number of PRBs occupied by the existing user equipment on the currently traversed carrier c1 is PRBsc1，PRBc1+PRBQoS<=PRBc1_totalThen, the allocation is successfully attempted, the service is allocated to the currently traversed carrier c1, and the total number of occupied PRBs on the carrier c1 is updatedc1=PRBc1+PRBQoSUpdating the total number of occupied PRBs (PRBs) on the original carrier c0 of the servicec0=PRBc0-PRBQoS(ii) a If PRBc1+PRBQoS>PRBc1_totalIf the carrier wave can not be allocated to the current carrier wave, continuously traversing the next service optional carrier wave; if the carrier capable of accommodating the service is not found after traversing all the service selectable carriers, the service fails to be allocated to other carriers, and the service still remains in the original carrier to participate in scheduling.
In the process of allocating each service attempt to other carriers, the process of ordering the service-selectable carriers includes: sorting the carriers selectable by the service according to a certain criterion; such as: sequencing based on the residual resource amount of each carrier or the channel quality of the user equipment on each carrier; when calculating the number of PRBs required for meeting the QoS requirement when the service is transmitted on the current carrier, the method in step 2 can be used to calculate the number of PRBs required for meeting the QoS requirement when the service is transmitted on the current carrierQoS。

When carrier selection is performed on user equipment to be currently scheduled based on data carrying capacity, appropriate carriers are sequentially selected for each user equipment to participate in scheduling by traversing the user equipment to be currently scheduled (namely the user equipment with non-empty data volume to be currently transmitted); and when each user equipment selects the carrier, the selection can be performed according to the data carrying capacity on each candidate carrier.
The network side selects the carrier for the current user equipment to be scheduled based on the data carrying capacity, and the method comprises the following steps: a network side determines a candidate carrier set of current user equipment; excluding the carriers with the residual PRB number of 0 from the carrier set configured for the user equipment, wherein the residual carriers are candidate carrier sets; for each candidate carrier in the determined candidate carrier set, calculating the data quantity which can be transmitted by the remaining resources of each candidate carrier according to the current remaining available PRB number of each candidate carrier and the broadband CQI information of the user equipment on each candidate carrier, and comparing the data quantity which can be transmitted by the remaining resources of each candidate carrier with the service data quantity to be transmitted of the current user equipment; if the data volume which can be transmitted by the residual resources of a plurality of candidate carriers is larger than or equal to the service data volume to be transmitted of the current user equipment, the network side selects the carrier with the highest broadband CQI information from the candidate carriers; otherwise (that is, the data amount which can be transmitted by the remaining resources of all the candidate carriers is less than the service data amount to be transmitted of the current user equipment), the network side selects the carrier with the largest data amount which can be transmitted by the remaining resources from all the candidate carriers.
It should be noted that the above description of the method is based on the user equipment performing carrier selection, that is, the user equipment is used as the granularity to select carriers, and the user equipment only selects one carrier each time the carrier is selected; the method is also suitable for selecting the carriers by taking the service as the granularity, namely different services of the same user equipment can select different carriers, and on the basis, a user can select a plurality of carriers each time the carriers are selected.
In the second mode, when carrier selection is performed on the user equipment to be currently scheduled based on the channel quality, appropriate carriers are sequentially selected for each user equipment to participate in scheduling by traversing the user equipment to be currently scheduled (namely the user equipment with the current data volume to be transmitted being non-empty); and when each user equipment selects a carrier, the selection can be performed according to the channel quality on each candidate carrier.
The network side selects the carrier for the current user equipment to be scheduled based on the channel quality, and the method comprises the following steps: a network side determines a candidate carrier set of current user equipment; excluding the carriers with the residual PRB number of 0 from the carrier set configured for the user equipment, wherein the residual carriers are candidate carrier sets; and the network side compares the broadband CQI value of the user equipment on each candidate carrier in the determined candidate carrier set, and selects the candidate carrier with the maximum broadband CQI value.

The network side selects the carrier for the current user equipment to be scheduled based on the residual resource amount, and the method comprises the following steps: a network side determines a candidate carrier set of current user equipment; excluding the carriers with the residual PRB number of 0 from the carrier set configured for the user equipment, wherein the residual carriers are candidate carrier sets; and the network side compares the residual available PRB number on each candidate carrier for each candidate carrier in the determined candidate carrier set, and selects the candidate carrier with the maximum residual available PRB number.
In the embodiment of the present invention, the performing, by the network side, shared channel resource allocation in parallel according to the to-be-transmitted service data allocated to each selected carrier respectively includes: in the scheduling process of the current round, when the scheduling policy based on the requirement of ensuring the QoS selects the carrier for the user equipment to be scheduled currently, the network side executes the resource allocation of the shared channel by adopting the following mode: for a certain carrier, determining user equipment to be scheduled on the carrier, wherein the user equipment to be scheduled selects the user equipment of the carrier in the carrier selection process; sequencing user equipment to be scheduled on the carrier wave to obtain a user queue to be scheduled; when the user equipment to be scheduled is sequenced, the user equipment which does not meet the requirement of the service QoS is arranged in front of a user queue to be scheduled as much as possible, and the user equipment which meets the requirement of the service QoS is arranged behind the user queue to be scheduled; and allocating shared channel resources to the user equipment in the user queue to be scheduled in sequence according to the criterion of meeting the service QoS requirement of the user equipment as much as possible, wherein the PRB resources allocated to the user equipment are not less than the number of PRBs required by meeting the service QoS requirement as much as possible.
When sequencing the user equipment to be scheduled on the carrier, the related sequencing method includes, but is not limited to: adopting a PF (Proportional-Fair) method or other sequencing methods, wherein the adopted sequencing method needs to make user equipment which does not meet the service QoS requirement be arranged in front of a user queue to be scheduled as much as possible, and make the user equipment which meets the service QoS requirement be arranged behind the user queue to be scheduled.
In the embodiment of the present invention, the performing, by the network side, shared channel resource allocation in parallel according to the to-be-transmitted service data allocated to each selected carrier respectively includes: in the scheduling process of the current round, when the scheduling strategy based on the improved transmission rate selects the carrier for the user equipment to be scheduled, the network side executes the resource allocation of the shared channel in the following way: for a certain carrier, determining user equipment to be scheduled on the carrier, wherein the user equipment to be scheduled selects the user equipment of the carrier in the carrier selection process; sequencing the user equipment to be scheduled on the carrier (the corresponding sequencing rule can adopt a method based on channel quality, such as sequencing according to broadband CQI information reported by the user equipment), so as to obtain a user queue to be scheduled; when the user equipment to be scheduled is sequenced, the user equipment with good channel quality is arranged in front of a user queue to be scheduled as much as possible, and the user equipment with poor channel quality is arranged behind the user queue to be scheduled; and allocating shared channel resources to the user equipment in the user queue to be scheduled in sequence according to the criterion of transmitting all the cache data of the user equipment as much as possible.

Aiming at the characteristics of a multi-carrier system, idle resources can be fully utilized to transmit data through multi-round scheduling; and the strategy of each round of scheduling can be dynamically changed according to the real-time scheduling condition, so that the scheduling is more flexible, the QoS performance of the service is better ensured, and the user rate and the system capacity are improved. In each round of scheduling process, firstly, carrier selection is carried out, and the service data to be transmitted is reasonably distributed to each carrier, so that the same user equipment can participate in scheduling on a plurality of carriers at the same time, the allocation of resources required by the user equipment is favorably completed as soon as possible, the scheduling round is reduced, and the processing time of the scheduling process is shortened; in each round of scheduling process, each carrier wave adopts a distributed parallel scheduling mode, and the processing time of one round of scheduling is shortened.
