Description
Technical field
The present invention relates to mobile communication technology field, particularly relate to a kind of resource allocation methods and device.
Background technology
Long Term Evolution (Long Term Evolution, LTE) system, as the wireless access system of next generation mobile communication network, has the advantage of large bandwidth, two-forty, low time delay, can be user and brings splendid mobile Internet to experience.
For improving the availability of frequency spectrum, LTE system adopts identical networking usually, but LTE system identical networking can cause minizone to there is interference, has a strong impact on the service quality of Cell Edge User (being namely in the user of cell edge).At present, general employing Inter-Cell Interference Coordination (Intet Cell Interference Cacellation, ICIC) technology suppresses presence of intercell interference, its basic thought by managing radio resources (comprising power resource and frequency domain resource), presence of intercell interference is controlled, and is a kind ofly to consider the Resourse Distribute in multiple community and the multiple cell radio resource management scenarios of carrying out.
In existing ICIC technology, first whether base station reports A3 event to come distinguishing cell edge customer and Cell Center User (being namely in the user of center of housing estate) by user terminal, concrete, base station pre-sets the parameter value (as bias) of A3 event, when user terminal judges that the difference of the signal quality value of its adjacent cell and the signal quality value of its main Serving cell is greater than default bias, report A3 event, the user terminal (abbreviation edge user terminal) that base station then will report the user terminal of A3 event to be defined as Cell Edge User, by the user terminal (central user terminal) not reporting the user terminal of A3 event to be defined as Cell Center User, then frequency domain resource is divided into two parts, distributes to central user terminal and edge user terminal respectively, simultaneously, user terminal distributes lower transmitting power, and is that edge user terminal distributes higher transmitting power.Especially, different base stations is that the frequency domain resource that its edge user terminal distributes is often different, thus makes to adopt the frequency domain resource of higher transmitting power mutually to stagger between neighbor cell, reduces presence of intercell interference.
Although above-mentioned ICIC technology can solve the problem of presence of intercell interference, but still there is following defect:
Base station, except covering outdoor road, also needs in covering chamber, for indoor user provides service.Because the loss of wireless signal is comparatively large, particularly outdoor signal penetrates body of wall when entering indoor, and the loss of wireless signal is larger, if thus LTE network will realize good in-door covering, then need higher transmitting power.But when adopting above-mentioned ICIC technology, because building blocks, the user terminal (abbreviation indoor user terminal) of indoor user generally can only receive the wireless signal of a community, i.e. main serving cell signal, and adjacent cell signal is general very weak, that is the difference of the signal quality value of adjacent cell and the signal quality value of main Serving cell can not exceed default bias, thus indoor user terminal can't report A3 event, therefore indoor user terminal will be defined as central user terminal by base station, lower transmitting power is distributed to indoor user terminal, thus cause the resource of distributing for indoor user terminal cannot meet its demand.

First, the embodiment of the present invention provides a kind of resource allocation methods, and the realization flow figure of the method as shown in Figure 1, mainly comprises the steps:
Step 11, determines the user terminal reporting A3 event in community;
In this step, when user terminal meets the entry condition of A3 event, then report A3 event;
The entry condition of A3 event is:
Mn+Ofn+Ocn-Hys＞Ms+Ofs+Ocs+Off
Wherein, Mn is the signal strength values of the adjacent cell that user terminal detects, Ofn is the frequency offset amount of adjacent cell, Ocn is the particular offset of adjacent cell, Hys is amount of hysteresis, and Ms is the signal strength values of the main Serving cell that user terminal detects, Ofs is the frequency offset amount of main Serving cell, Ocs is the particular offset of main Serving cell, and Off is A3 event offset amount; Wherein, parameter Ofn, Ocn, Hys, Ofs, Ocs and Off are all that base station pre-sets and sends to user terminal.
Step 12, according to the information reporting the user terminal to send up of A3 event determined, determines the parameter value of the signal strength signal intensity of the user terminal characterizing A3 event;
Step 13, according to the parameter value determined, does not report in the user terminal of A3 event from community, determines the user terminal meeting the indoor user terminal judgment condition pre-set;
In the embodiment of the present invention, when the parameter value of the signal strength signal intensity for characterizing the user terminal reporting A3 event determined is different, then indoor user terminal judgment condition also can be different.
Such as, when the parameter value determined is average descending circuit loss value, this indoor user terminal judgment condition specifically comprises: the descending path loss estimated value of user terminal be greater than average descending circuit loss value, the first bias pre-set and the amount of hysteresis Hys that pre-sets this three's and value; Wherein, the descending path loss estimated value of user terminal obtains according to its power headroom reporting (PHR) reported.
