In embodiment, RB is the sub-frame resources of downlink.
Wherein, search space is the parameter of user class, there is periodicity, simultaneously scans for space and also corresponds to different levels of repetition
And polymerization grade.Each the corresponding search space UE to be dispatched can be identical, can not also be identical.
In the embodiment of the present invention, resource scheduling device obtains the resource allocation information of downlink resource, and resource allocation information is used
In determining whether downlink resource is occupied；If being determined in downlink resource according to resource allocation information with the presence or absence of empty resource downlink
There is empty resource in resource, then according to determine to meet in empty resource the first preset condition to scheduling user's set UE points
With narrowband Physical Downlink Control Channel NPDCCH resource；Wherein, empty resource indicates unappropriated and continuous radio bearer
RB；First preset condition includes the downlink control there are transmitting uplink data demand and for carrying the transmission of dispatching uplink data
RB quantity needed for information DCI is less than or equal to the position RB of the RB quantity of empty resource and empty resource instruction wait dispatch
Within UE current search space.In this way, being that there are the UE to be dispatched of transmitting uplink data demand distribution according to empty resource
NPDCCH resource, it is possible to reduce the fragment of resource, and then resource utilization is improved, reduce the wasting of resources.
In specific implementation, step 401 is realized by following manner：Initialize uplink and downlink resource and scheduling parameter.According to cell
Configuration information, including broadcast and common signal channel configuration information, calculate current area fixed resource service condition, which are fixed
It is mapped in uplink time/frequency source list and down time-frequency the Resources list.It is then possible to it needs to be determined that downlink resource resource
When distributing information, the occupancy situation of downlink resource is determined according to down time-frequency the Resources list.
When entering current dispatching cycle, first obtain unappropriated RB resource, and combine be currently received respectively wait adjust
The resource requirement of UE is spent, distributes uplink and downlink resource for respectively UE to be dispatched.Specifically, can estimate before scheduling each wait dispatch
UE is used to send the scheduling resource quantity of DCI and is somebody's turn to do the search space information of the NPDCCH resource of UE to be dispatched.Due to it is each to
Dispatching the corresponding search space UE may be different, thus for this when dispatching the NPDCCH resource of UE scheduling transmission DCI, need
RB resource is judged whether within the search space of the UE to be dispatched, if the RB resource cannot function as not in search space
Send the NPDCCH resource of DCI；If in search space, it is contemplated that being provided the RB resource as the NPDCCH for sending DCI
Source.
In a kind of optional embodiment, determine in the downlink resource with the presence or absence of empty resource, including following implemented
Mode：According to the resource allocation information, at least one set of unappropriated continuous RB is determined from the downlink resource；For every
The unappropriated continuous RB of group, executes：Exist if the quantity of the unappropriated continuous RB of the group is less than default RB amount threshold and is greater than
The minimum of RB quantity needed for the UE respectively to be dispatched of transmitting uplink data demand is used to carry the DCI of dispatching uplink data transmission
Value, it is determined that the unappropriated continuous RB of the group is empty resource.If the quantity of the unappropriated continuous RB of the group is greater than default RB number
Threshold value is measured, there are the UE respectively to be dispatched of transmitting uplink data demand to be used for alternatively, the quantity of the unappropriated continuous RB of the group is greater than
The minimum value of RB quantity needed for carrying the DCI of dispatching uplink data transmission, it is determined that the unappropriated continuous RB of the group is not empty
Hole resource.In this way, each group of cavity resource determined can meet at least one UE to be dispatched needed for RB quantity.
For example, there are the UE respectively to be dispatched of transmitting uplink data demand 4, and each UE to be dispatched is adjusted for carrying
Spend transmitting uplink data DCI needed for RB quantity be respectively：UE1Need 4 RB, UE2Need 4 RB, UE38 RB are needed,
UE4Need 16 RB, it is seen then that the minimum of RB quantity needed for respectively UE to be dispatched is used to carry the DCI of dispatching uplink data transmission
Value is 4.
For example default RB amount threshold is 10, the quantity of first group of unappropriated continuous RB is 3, and second group is vacant
The quantity of continuous RB be 8, it is seen then that the quantity 3 of first group of unappropriated continuous RB is less than default RB amount threshold 10, but small
In the minimum value 4 respectively wait RB quantity needed for dispatching UE, therefore, first group of unappropriated continuous RB is not empty resource；Second
The quantity 8 of the unappropriated continuous RB of group is less than default RB amount threshold 10, and be greater than respectively wait RB quantity needed for dispatching UE most
Small value 4, therefore, second group of unappropriated continuous RB is empty resource.
Further, in above-mentioned steps 402, the empty resource determined may have multiple UE to can be used as UE to be dispatched,
In order to reasonably distribute resource, so that empty resource is maximumlly utilized, a kind of optional embodiment presented below：It is described
First preset condition further includes：The UE to be dispatched is that there are be used to carry dispatching uplink number in the UE of transmitting uplink data demand
The smallest UE of RB number differences of RB quantity needed for DCI according to transmission and the empty resource.
That is, after determining empty resource, it is multiple if it exists to meet there are transmitting uplink data demand and use
The RB quantity needed for the Downlink Control Information DCI of carrying dispatching uplink data transmission is less than or equal to the RB of the empty resource
The UE of condition of the position RB of quantity and the empty resource instruction within the current search space the UE to be dispatched, this
The RB number of RB quantity needed for Downlink Control Information DCI in multiple UE for carrying the transmission of dispatching uplink data and empty resource
The difference minimum UE of amount is UE to be dispatched, in this way, empty resource allocation gives the downlink transmitted for carrying dispatching uplink data
The smallest UE to be dispatched of RB number differences of RB quantity needed for controlling information DCI and empty resource, so that empty resource to the greatest extent may be used
Occupied, the unappropriated RB of appearance as few as possible of energy, and then resource utilization can be maximumlly improved, avoid resource unrestrained
Take.
Further, after step 402, further include：If it is determined that there is no empty resources in the downlink resource, then from
For there are the UE to be dispatched of downlink data transmission demand to distribute NPDCCH resource and NPDSCH resource in the downlink resource.
In the embodiment of the present invention, after searching empty resource, further include：Update the resource allocation of the downlink resource
Information, resource allocation information after being updated；Resource allocation information indicates all occupied, Yi Jiwei of downlink resource after update
Occupied resource.If it is determined that resource allocation information meets the second preset condition after the update, then terminate current scheduling；It is described
Second preset condition includes that the downlink resource total amount of the downlink resource distribution reaches default total amount threshold value, or, described current
The quantity that the UE to be dispatched of resource has been distributed in dispatching cycle reaches preset quantity threshold value.In this way, each scheduling week can be made
Resource carries out reasonable distribution in phase, improves resource utilization.
It can be setting scheduling each dispatching cycle threshold value in specific implementation.On the one hand, there are upstream data biographies for setting
The UE to be dispatched of defeated demand and there are the total quantitys of the UE to be dispatched of downlink data transmission demand, i.e. preset quantity threshold value.It is another
Aspect, setting downlink resource distribute total amount, i.e., default total amount threshold value.Scheduling threshold value can be configured according to actual needs.
In conjunction with above-described embodiment, at the current scheduling moment, according to resource unappropriated in current system, wait dispatch UE needed for
RB quantity it is as follows to be scheduled sequence in conjunction with the search result of empty resource：
Firstly, searching downlink metric space whether there is empty resource, and if it exists, it is preferential to carry out uplink scheduling process, from
UE to be dispatched is extracted in upstream request list, is assigned to this wait dispatch NPDCCH needed for UE for the cavity this section of RB is resource matched, it is excellent
It selects NPDCCH to take cavity position, while considering that uplink NPDSCH resource meets be adapted to scheduling relationship.If it does not exist, preferentially
Descending scheduling process is carried out, NPDCCH resource and NPDSCH resource are dispatched, scheduled NPDCCH and NPDSCH meet (n+5+
k0) sequential relationship.Later, record dispatching sequence and by the resource updates of distribution to resource allocation information at this time, while record is worked as
The uplink and downlink sum of preceding distribution and the downlink resource total amount distributed.If the downlink resource total amount of downlink resource distribution reaches default
Total amount threshold value terminates alternatively, the quantity in the UE to be dispatched of current scheduling period distribution resource reaches preset quantity threshold value
Current dispatching cycle.In this way, uplink scheduling can be allocated to reasonable arrangement uplink and downlink dispatching sequence, the interval resource of descending scheduling
DCI, and then improve the efficiency of more UE scheduling, reduce the blind operation for searching resource of UE.
