For the purpose that makes the embodiment of the invention, technical scheme, and advantage clearer, below the technical scheme that the embodiment of the invention provides is elaborated with reference to accompanying drawing.
See also Fig. 1, the resource allocation methods flow chart for the embodiment of the invention provides comprises:
Step 101: the base station obtains the resource requirement statistic of relay station, and wherein, described resource requirement statistic can comprise: at least one in forward channel resource requirement statistic and the reverse channel resources demand statistic;
In actual applications, described resource requirement statistic can be added up by the base station, and the resource requirement statistic that then described base station obtains relay station specifically comprises:
The stock number that base station periodicity or acyclic statistics relay station need, wherein, the stock number that the base station can adopt following several method statistics relay station to need:
One, this relay station average discharge in periodicity or the acyclic statistics Preset Time calculates (estimation) and goes out resource requirement statistic (at least one in forward channel resource requirement statistic and the reverse channel resources demand statistic).Such as, can preestablish the average discharge of base station in 60 minutes statistics relay stations 30 minutes, and according to described average discharge computational resource requirements statistic.
Two, when estimation forward channel resource requirement statistic, can also pass through the data congestion amount of this relay station by accounting base-station, then,, calculate (estimation) forward channel resource requirement statistic according to described data congestion amount to end side.
Three, when estimation reverse channel resources demand statistic, can also from the reverse channel resources demand information of terminal, obtain the reverse channel resources demand of terminal, then, the reverse channel resources demand of each terminal that statistics gets access to obtains reverse channel resources demand statistic.Wherein, the reverse channel resources demand information is to send to relay station by terminal, and send to the base station by relay station, therefore, in actual applications, the base station is when statistics reverse channel resources demand statistic, and the reverse channel resources demand statistics of obtaining in the reverse channel resources demand information with same relay station transmission obtains the reverse channel resources demand statistic of this relay station together.
Perhaps, described resource requirement statistic can be added up by relay station, then further comprises before the base station obtains the resource requirement statistic of relay station:
Relay station periodically or its stock number that needs of acyclic statistics and is sent to described base station with the resource requirement statistic, and wherein, relay station can adopt following several method to add up it needs stock number:
One, this relay station average discharge in periodicity or the acyclic statistics Preset Time estimates resource requirement statistic (at least one in forward channel resource requirement statistic and the reverse channel resources demand statistic).
Two, when estimation reverse channel resources demand statistic, can also add up the reverse channel resources demand of each terminal, calculate (estimation) reverse channel resources demand statistic, wherein, the reverse channel resources demand of each terminal can obtain from terminal sends to the reverse resource requirement information of base station by relay station.
Three, when estimation forward channel resource requirement statistic, can add up the data congestion amount of current relay station,, calculate (estimation) forward channel resource statistics amount according to described data congestion amount to the terminal direction.
Step 102: the base station is described relay station Resources allocation according to described resource requirement statistic;
In actual applications, step 102 specifically comprises: according to described resource requirement statistic, determine to distribute to the resource quantity and the resource location of described relay station, and described resource quantity and position are sent to relay station.So far finished process into the relay station Resources allocation.
In the technical scheme that the embodiment of the invention provides, owing to being that relay station is current, the resource requirement statistic serves required total resources for terminal in its coverage provides, therefore, the technical scheme that the embodiment of the invention provides is according to the resource requirement statistic, give relay station with the total resources primary distribution of the current needs of relay station, reduce the Signalling exchange quantity between base station and relay station, saved Internet resources.
