Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
The present embodiment provides a kind of distribution method of resource, and the method is applicable to the wireless communication system of bandwidth resources symmetry, such as CDMA, WCDMA or FDD LTE.First base station obtains ascending resource needed for terminal traffic and required downlink resource, if required ascending resource is greater than required downlink resource, then base station adjusts part resource as ascending resource from downlink resource; If or required downlink resource is greater than required ascending resource, then base station adjusts part resource as downlink resource from ascending resource, thus reaches according to the different object of carrying out distributing of the bandwidth resources of required uplink and downlink.Further, base station sends the resource information after adjustment to terminal, carries out the transmission of business to make terminal according to the resource after adjustment.
The present embodiment with the base station in FDD LTE for executive agent is illustrated.
As shown in Figure 1, be the schematic flow sheet of the distribution method of the resource according to the present embodiment.
Step 101, obtains ascending resource needed for terminal traffic and required downlink resource, one larger in required ascending resource and required resource be resource to be increased, less one be resource to be reduced.
Alternatively, above-mentioned ascending resource can be uplink bandwidth resource, and above-mentioned downlink resource can be downlink bandwidth resource.
In the present embodiment, base station can by adding up the ascending resource and required downlink resource that obtain needed for terminal traffic, ascending resource needed for the terminal traffic added up and required downlink resource can be add up the ascending resource needed for the terminal traffic in preset time period and required downlink resource, such as, add up the uplink bandwidth resource needed for terminal traffic in month and required downlink bandwidth resource, and it is larger to compare which demand.Certainly, in actual applications, base station also can obtain ascending resource needed for terminal traffic and required downlink resource by the statistics of other entity.
Step 102, adjusts part resource to resource to be increased from resource to be reduced.
Particularly, if when the ascending resource needed for terminal traffic is greater than downlink resource, then resource to be increased is ascending resource, and resource to be reduced is downlink resource; If when the downlink resource needed for terminal traffic is greater than ascending resource, resource to be increased is downlink resource, and resource to be reduced is ascending resource.Preferably, the ratio of ascending resource needed for added up terminal traffic and required downlink resource part resource can be adjusted to resource to be increased from resource to be reduced.Such as, if the ascending resource needed for terminal traffic is greater than downlink resource, then the ascending resource needed for the terminal traffic of statistics and the ratio of required downlink resource adjust out part resource as ascending resource from downlink resource; If the downlink resource needed for terminal traffic is greater than ascending resource, then the ascending resource needed for the terminal traffic of statistics and the ratio of required downlink resource adjust part resource as downlink resource from upstream bandwidth.
Can imagine, when the ascending resource needed for pending business equals required downlink resource, owing to there is not the problem of the upstream or downstream wasting of resources, so also just need not current resource be adjusted.
Step 103, to terminal down distributing resource configuration messages, this resource distribution message described comprises the information of the ascending resource after adjustment and downlink resource, carries out the transmission of business to make described terminal according to the ascending resource after described adjustment and downlink resource resource distribution message.
Base station, according to the ascending resource after adjustment and downlink resource resource, generates corresponding resource distribution message, and issues to terminal.Terminal obtains the ascending resource after adjustment and downlink resource according to resource distribution message, and carries out the transmission of business according to the ascending resource after adjustment and downlink resource.
According to the distribution method of the resource of the present embodiment, first the ascending resource needed for terminal traffic and downlink resource are added up, when required ascending resource is greater than downlink resource, part resource is adjusted as ascending resource from downlink resource, or when required downlink resource is greater than ascending resource, part resource is adjusted as downlink resource from ascending resource, and resource information after adjustment is sent to terminal, terminal carries out the transmission of business according to the resource information after this adjustment, thus solve the problem of ascending resource or the downlink resource waste caused because of required ascending resource and downlink resource imbalance in existing wireless communication system.
Embodiment two
The present embodiment provides a kind of distribution method of resource based on embodiment one.
Step 201, obtains ascending resource needed for terminal traffic and required downlink resource, one larger in described required ascending resource and required downlink resource be resource to be increased, less one be resource to be reduced.
Alternatively, above-mentioned ascending resource can be uplink bandwidth resource, and downlink resource can be downlink bandwidth resource.
The particular content of this step is consistent with step 101, does not repeat them here.
Step 202, the ratio of the ascending resource needed for terminal traffic and required downlink resource adjusts part resource to described resource to be increased from resource to be reduced.
Before adjustment, resource to be reduced and resource to be increased are S, when the ratio of required resource to be reduced and required resource to be increased be P:Q and as P < Q time, from resource to be reduced, adjust [(Q-P)/(Q+P)] × S to resource to be increased.
Such as, uplink bandwidth resource is 5M, downlink bandwidth resource is 5M, when the ratio of required uplink bandwidth resource and required downlink bandwidth resource is 2:3, can from adjusting 1M bandwidth resources uplink bandwidth resource to downlink bandwidth resource, like this, the ratio of the uplink bandwidth resource after adjustment and the downlink bandwidth resource after adjusting is just 2:3.
Wherein, from resource to be reduced, adjust fractional bandwidth resource specifically comprise to resource to be increased:
Partial-band resource be adjusted to resource to be increased from resource to be reduced; Or
Partial time slot resource be adjusted to resource to be increased from resource to be reduced.
Frequency band is exactly the frequency range allowing the highest frequency of the signal transmitted and allow the low-limit frequency of signal that transmits between this, and it can be made up of multiple frequency spectrum.Preferably, the band resource being in edge in bandwidth to be reduced is distributed to resource to be increased.This be due to, in existing wireless communication system, all determine by center frequency point and bandwidth the frequency band that receipts/machine of sending out receives or sends, if give bandwidth resources to be increased by the intermediate frequency band Resourse Distribute in bandwidth to be reduced, then original bandwidth resources to be reduced can be cut into 2 sections, now just need a corresponding 2 receipts/machine, band resource submarginal in bandwidth to be reduced is distributed to resource to be increased and then can avoid occurring such problem.It is pointed out that and by 1 spectrum allocation may in bandwidth submarginal in bandwidth resources to be reduced to resource to be increased, also can distribute 2 frequency spectrums, specifically can sets itself according to actual needs.
When base station determines that needed for terminal traffic, ascending resource is greater than required downlink resource, originally the part downstream bands resource be used as in downlink resource is adjusted as ascending resource, this part downstream bands resource is called time ascending resource, using upstream band resource originally as main upstream band resource.As shown in Figure 2 A, for the band resource of the close both sides of the edge in downstream bands resource being used as the schematic diagram of upstream band.
In like manner, when base station judges that needed for pending business, downlink bandwidth resource is greater than required uplink bandwidth resource, part upstream band resource downlink bandwidth resource will be adjusted from uplink bandwidth resource, this part downlink frequency resource band is called time downlink bandwidth resource, and downlink bandwidth is originally main downlink bandwidth.As shown in Figure 2 B, for the band resource of the close both sides of the edge in upstream band being adjusted the schematic diagram as downstream bands.
Time interval resource is the performance of the actual acquisition frequency resource of physical layer.First by the frequency range that whole bandwidth partition is different, the user in same frequency range reallocates different time interval resources, and the time interval resource of each CU is exactly a channel.
When base station judges that required uplink bandwidth resource is greater than required downlink bandwidth resource, to originally be used as the part descending time slot resource of downlink bandwidth resource as ascending time slot resource, this part descending time slot resource is called time uplink bandwidth resource, using uplink bandwidth resource originally as main uplink bandwidth resource.As shown in Figure 3A, for using the schematic diagram of the part descending time slot resource in downlink bandwidth as ascending time slot resource.
In like manner, when base station determines that required downlink resource is greater than required uplink bandwidth resource, to originally be used as the part ascending time slot resource of uplink bandwidth resource as descending time slot bandwidth resources, this part ascending time slot resource is called time downlink bandwidth resource, and downlink bandwidth resource is originally called main downlink bandwidth resource.As shown in Figure 3 B, for using the schematic diagram of the part ascending time slot resource in uplink bandwidth resource as descending time slot resource.
Step 203, to terminal down distributing resource configuration messages, described resource distribution message comprises the information of the ascending resource after adjustment and downlink resource, carries out the transmission of business to make terminal according to the ascending resource after adjustment and downlink resource.
The mode of base station notification terminal resource distribution message can be sent by broadcast, and resource distribution message specifically can comprise: the bandwidth of subband, the center frequency point of this subband of the bandwidth of the main band of upstream or downstream, the center frequency point of this main band, corresponding upstream or downstream.
Required uplink bandwidth resource is greater than to the situation of required downlink bandwidth resource, base station at the PDCCH(physical downlink control channel of downstream bands, Physical Downlink Control Channel) on the resource distribution message distributing to terminal is sent to terminal.Terminal, after receiving resource distribution message, only sends up control signal to base station on Your Majesty's uplink bandwidth.Base station sends resource distribution message by downstream bands, uplink scheduling information comprises: RB(Resource Block, wireless resource block) number, RB position, MCS(Modulation and Coding Scheme, modulation and coded system) exponent number, upstream band information, terminal, according to this uplink scheduling information, the frequency band of specifying, the RB position of specifying, MCS exponent number carries out transfer of data.
Required downlink bandwidth resource is greater than to the situation of required uplink bandwidth resource, base station sends resource distribution message to terminal on main downlink bandwidth, base station only issues uplink scheduling information on main downlink bandwidth, uplink scheduling information comprises: RB(wireless resource block, Resource Block) number, RB position, MCS(wireless resource block, Resource Block) exponent number, upstream band information.Base station scheduling data service, control signal can issue by the PDDCH on main downlink bandwidth, also can issue by the PDDCH on secondary downlink bandwidth.
According to the distribution method of the resource of the present embodiment, when required ascending resource is greater than downlink resource, partial-band resource is adjusted as ascending resource from downlink resource, or when required downlink resource is greater than ascending resource, from upstream bandwidth, adjust partial-band resource as downlink resource, thus solve the problem of ascending resource or the downlink resource waste caused because of required ascending resource and downlink resource imbalance in existing wireless communication system.
