Embodiment
Basic thought of the present invention is: the broadband tenability of the user terminal of supporting according to relay system is carried out the setting of main polymerization carrier wave, so that the compatible all user terminals of main polymerization carrier wave energy, and the corresponding relation of pairing main polymerization carrier wave and auxilliary polymerization carrier wave when all types of user terminals being set inserting, system can carry out the selection of main polymerization carrier wave and auxilliary polymerization carrier wave according to current user terminal access situation.And can be the mode that user terminal is determined resource allocation, and notify this user terminal according to the broadband tenability of active user's terminal.The present invention can realize the distribution of main polymerization carrier wave and auxilliary polymerization carrier wave neatly, and usage factor of system resource is higher.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the flow chart of definite method of carrier aggregation in the junction network of the present invention, and as shown in Figure 1, definite method of carrier aggregation may further comprise the steps in the junction network of the present invention:
Step 101: the bandwidth ability of all user terminals of supporting need in the cordless communication network to be determined in the base station.
The bandwidth ability of all user terminals of supporting need in the cordless communication network (relay system) to be determined in the base station, and the bandwidth ability of user terminal is determining main polymerization carrier wave to need the amount of bandwidth and the quantity of backward compatibility when forming.That is to say, main polymerization carrier wave need be determined the current type of user terminal of not supporting the polymerization carrier wave, these do not support the bandwidth of carrier wave that user terminal is supported of polymerization carrier wave and frequency etc., with when determining main polymerization carrier wave, with the component carrier of the carrier wave in the original system as main polymerization carrier wave, and the channel characteristics in the maintenance primary carrier, thereby realize user terminal backward compatibility in the original system (may be a plurality of systems).
Step 102: the carrier resource polymerization of base station selected complete backward compatibility forms main polymerization carrier wave.
The carrier resource polymerization of base station selected complete backward compatibility forms main polymerization carrier wave, when selecting carrier resource to form main polymerization carrier wave, fully take into account the bandwidth ability of user terminals all in the cordless communication network.The new carrier wave that main polymerization carrier wave forms will help reducing the complexity of base station resource scheduling as a unified scheduling of new main carrier.In order to improve spectrum efficiency, the different bandwidth capabilities of user terminal is divided into groups in advance, when selecting resource to form main polymerization carrier wave, select different carrier resources to form main polymerization carrier set, each subclass in the set is corresponding to the grouping of different bandwidth capabilities.For example, when the user terminal bandwidth ability below the existence in the cordless communication network, 3MHz, 5MHz, 10MHz, 20MHz, 50MHz, 100MHz, bandwidth ability is carried out following grouping, promptly, { 3MHz, 5MHz, 10MHz}, { 20MHz, 50MHz, two groups of 100MHz}, corresponding when forming main polymerization carrier wave, each group forms at least one main polymerization carrier wave, for three kinds of carrier waves of backward compatibility, can select the least common multiple of all carrier waves of backward compatibility in each group, for first group, the carrier wave that can select 30MHz is as main polymerization carrier wave, and for second group, the carrier wave that can select 100MHz is as main polymerization carrier wave.Need to prove, selected main polymerization carrier wave, as long as the carrier wave in the compatible original system, the bandwidth of promptly main polymerization carrier wave contains all existing carrier waves and gets final product, and not necessarily must select the least common multiple of all bandwidth in aforementioned group for use.During the base station scheduling carrier resource, can also can dispatch each group respectively to the unified scheduling of all groups in the main polymerization carrier wave.
The resource of main polymerization carrier wave can be a static configuration, for example, the bandwidth ability of supporting according to all user terminals in the relay system, main polymerization carrier wave when determining the different user terminals type respectively and auxilliary polymerization carrier wave, like this, after reporting of user bandwidth tenability, can determine that according to the type of user terminal of group under it and current access current needs are distributed to or the main polymerization carrier wave of user terminal and auxilliary polymerization carrier wave.Certainly, the resource of main polymerization carrier wave also can be a Dynamic Selection, can form new bandwidth ability grouping again according to the current state of affairs of wireless communication system, the current bandwidth ability distribution situation of user terminal, and form new main polymerization carrier wave set.The selection of main polymerization carrier wave, the incomplete bandwidth ability of all user terminal of backward compatibility, the user terminal that a backward compatibility is being served just can meet the demands.
And in the selection of auxilliary polymerization carrier wave, also can be according to the demand of backward compatibility, according to the set different group of aforementioned main polymerization carrier wave, with the group of auxilliary polymerization allocation of carriers to main polymerization carrier wave place.Dispatch all auxilliary polymerization carrier waves in the group when scheduling of resource jointly the base station, to reduce the complexity of scheduling.

The base station is provided with the threshold value that main and auxiliary polymerization carrier resource distributes, and is used for the link-quality according to base station or relay station, reasonably distributes main and auxiliary polymerization carrier resource between base station and relay station.The setting of threshold value is determined according to system's characteristics and empirical value.
Step 104: the base station sends to relay station with allocation threshold.
Step 105: user terminal measurement channel quality information, and reporting base station or relay station.
User terminal measurement channel quality information, and reporting base station or relay station, this is that therefore, the result that user terminal will be measured will report and be its serving base station or relay station because active user's terminal may be inserted by base station or relay station.
Step 106: base station or relay station contrast measurement result and allocation threshold, and determine the up link and the main and auxiliary carrier resource method of salary distribution of down link according to the bandwidth ability of user terminal.
Base station or relay station are with measurement result and allocation threshold contrast, and determine up link and the main and auxiliary carrier resource allocative decision of down link according to the bandwidth ability of user terminal, mainly be the distribution condition of determining main and auxiliary polymerization carrier resource, that is, all be distributed on the relay station; Main polymerization carrier resource on the relay station, auxilliary polymerization carrier resource is on the base station; Main polymerization carrier resource on the base station, auxilliary polymerization carrier resource is on relay station, simultaneously according to the amount of bandwidth of the main and auxiliary polymerization carrier wave of bandwidth ability reasonable distribution of user terminal.
Step 107: base station or relay station are determined main and auxiliary polymerization carrier resource according to Resource Allocation Formula.
Step 108: base station or relay station by uplink grant with main and auxiliary polymerization carrier resource allocative decision informing user terminal.
Determine the bandwidth ability of user terminal in the cordless communication network by base station or relay station, the base station in Radio Resource, select the carrier resource of different bandwidth ability carry out polymerization form new have bigger bandwidth ability and with the existing wireless communications network system in the new main carrier set of bandwidth ability backward compatibility of user terminal, be called main polymerization carrier wave.Main polymerization carrier wave is used for carrying the control information of crucial control signaling and important physical process.Except other carrier resources of main polymerization carrier wave can carry out the carrier wave that polymerization forms all user terminal bandwidth ability of incomplete backward compatibility at the dissimilar user terminal in the cordless communication network, be called auxilliary polymerization carrier wave.Auxilliary polymerization carrier wave is used to carry relevant data message etc.Base station and relay station are according to the measurement result of relay station and user terminal, base station and relay station on select main polymerization carrier resource and auxilliary polymerization carrier resource to relay station and relay station to the two-way link between the user terminal for base station in up link and the down link, improved radio communication quality as much as possible.
