Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of distribution method and device of channel resource.
Background technology
Downlink user both can have been dispatched at some descending sub frame in base station also can dispatching uplink user, the ascending-descending subframes of take configuration 1 is example, in a radio frames, base station can be at descending sub frame 0, 1, 4, 5, 6, 9 dispatching downlink users, but can only be at descending sub frame 1, 4, 6, 9 dispatching uplink users, that is to say that base station is at descending sub frame 0, 5 can only dispatching downlink user, in subframe 1, 4, 6, 9 both can dispatching downlink user also can dispatching uplink user, in these subframes, descending sub frame n dispatches PDSCH (the Physical Downlink Shared CHannel of this subframe, Physical Downlink Shared Channel), PUSCH (the Physical Uplink Shared CHannel of descending sub frame n scheduling n+k subframe, Physical Uplink Shared Channel), as shown in Figure 1.
Wherein, k value is determined by following table:
Obviously, for these subframes, PDCCH (the Physical Downlink Control Channel of scheduling PDSCH and scheduling PUSCH, Physical Downlink Control Channel) resource is shared for up-downgoing, because PDCCH is limited, thereby need between dispatching downlink user and dispatching uplink user's PDCCH resource, carry out reasonable distribution.
Prior art scheme thought is as follows:
The spendable PDCCH number of resources of the descending maximum of initialization is (with CCE (Control Channel Element, control channel unit) characterize), be designated as N_CCE_dl_max, in historical a period of time T, be recorded as to be scheduled descending with UE (User Equipment, number of success and the frequency of failure while subscriber equipment) distributing PDCCH resource, and then obtain descending PDCCH resource distribution mortality; Number of success and the frequency of failure while being recorded as uplink UE distribution PDCCH resource to be scheduled, and then obtain up PDCCH resource and distribute mortality, by more descending PDCCH resource, distribute mortality and up PDCCH resource to distribute the relation between mortality, judgement is that descending PDCCH resource is more limited or up PDCCH resource is more limited, if judge that descending PDCCH resource is more limited, upgrade N_CCE_dl_max: N_CCE_dl_max is increased to a step-length (CCE number); If judge that up PDCCH resource is more limited, upgrade N_CCE_dl_max: N_CCE_dl_max is reduced to a step-length.
Prior art has following defect: 1, N_CCE_dl_max initial value is more difficult determines, does not now have the historical information can be for reference, before N_CCE_dl_max upgrades first during this period of time in, described in the 2nd, problem may be more serious; 2, historical statistics information can not the up-downgoing of Accurate Prediction current scheduling subframe the real demand of scheduling, easily cause occurring that the descending PDCCH(PDSCH of being limited to still has residue) can not dispatch more users and the situation of the up PDCCH of the existence wasting of resources; 3, according to historical statistics information, N_CCE_dl_max is adjusted and lags behind all the time variation.
Therefore, the unreasonable distribution of prior art to PDCCH resource, has reduced the utilance of channel resource.

Otherwise, according to all treating the PDCCH total resources that dispatching downlink UE is required and all treating the proportionate relationship between the required PDCCH total resources of dispatching uplink UE, and whole available PDCCH resources, determine respectively to distribute to and all treat the PDCCH total resources of dispatching downlink UE and distribute to the PDCCH total resources of all treating dispatching uplink UE.
9. device as claimed in claim 7, is characterized in that, described in estimate resource allocation unit, specifically for:
According to described, distribute to the PDCCH total resources of all treating dispatching downlink UE, and the priority query of descending UE to be scheduled, for descending UE to be scheduled distributes PDCCH resource;
And, according to described, distribute to the PDCCH total resources of all treating dispatching uplink UE, and the priority query of uplink UE to be scheduled, for uplink UE to be scheduled is distributed PDCCH resource.
10. device as claimed in claim 6, is characterized in that, this device also comprises:
Surplus resources is determined first module, for judging whether PDCCH resource also has residue;
Surplus resources is determined second unit, when determining that when surplus resources first module determines that PDCCH resource remains in addition, judges whether PDSCH resource and/or PUSCH resource have residue;
Surplus resources allocation units, while only having PDSCH resources left for determining that when surplus resources second unit is definite, are that the to be scheduled descending UE of unallocated channel resource distributes PDCCH and PDSCH;
When surplus resources, determining second unit and determine while only having PUSCH resources left, is that the uplink UE to be scheduled of unallocated channel resource is distributed PDCCH and PUSCH;
When surplus resources determines that second unit determines that PDSCH resource and PUSCH resource all have residue, the size of the PDCCH resource that more current descending UE to be scheduled and uplink UE are required, is the less UE allocation of channel resources of required PDCCH resource.
