Problems solved by technology

For the far-point terminal located at the edge of the cell, due to the limited spectrum resources of the far-point terminal, if the priority is only adjusted by the instantaneous rate and the long-term average rate, and the wireless resources are allocated accordingly, the data transmission rate of the far-point terminal It is still very lo

Embodiment 1

[0027] In order to solve the problems of less opportunities for far-point terminals to call wireless resources, poor signal quality, and poor system fairness in a carrier aggregation communication system, an embodiment of the present invention provides a wireless resource scheduling method, which can be applied to such as figure 1 As shown in the communication system, such as figure 2 As shown, the method includes:

[0028] 201: Determine available carrier information of the terminal.

[0029] Wherein, the available carrier information includes available carrier quantity and available carrier frequency.

[0030] As a specific embodiment, the base station sends a pilot signal to the terminal, the terminal processes the received pilot signal, and feeds back location information to the base station, and the base station determines the available carrier of the terminal according to the preset rules according to the location information fed back by the terminal information, incl...

Embodiment 2

[0049] Further, as a figure 2 As a refinement and extension of the method shown, this embodiment also provides a method for wireless resource scheduling, such as image 3 As shown, the method includes:

[0050] 301: Determine available carrier information of the terminal.

[0051] 302: Determine the value of a parameter factor corresponding to each service parameter according to the value of the service parameter of the current service and a preset mapping relationship table.

[0052] The preset mapping relationship table includes the corresponding relationship between the value of the service parameter and the value of the parameter factor. Table 2 to Table 4 are a specific implementation of the preset mapping relationship table. The preset mapping relationship table gives An example of the corresponding relationship between the value of the business parameter and the value of the parameter factor is shown as follows:

[0053] Table 2 Correspondence between service bearer...

Embodiment 3

[0074] The embodiment of the present invention also provides an apparatus 40 for wireless resource scheduling, which is used to execute the method described above, such as Figure 4 As shown, the device 40 includes:

Abstract

The invention discloses a wireless resource scheduling method and apparatus, and relates to the technical field of communication. The problems of poor signal quality and poor system fairness of a remote terminal can be solved. The wireless resource scheduling method disclosed by the invention comprises the following steps: determining available carrier information of a terminal, wherein the available information comprises an available carrier number and available carrier frequency; calculating a weight factor according to the available carrier information and a business parameter of current business, wherein the business parameter comprises at least one of a business bearer type, a time delay and a packet loss rate; calculating the corresponding priority of the terminal when transmitting data on each available carrier according to the weight factor, the instant transmission rate of the terminal when transmitting data on each available carrier and the average transmission rate of the terminal when transmitting data on each available carrier; and determining the available carriers with priorities meeting preset requirements as carriers for data transmission. The wireless resource scheduling method and apparatus disclosed by the invention is suitable for application in communication systems with carrier aggregation functions.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for scheduling wireless resources. Background technique [0002] A carrier aggregation (Carrier Aggregation, CA) technology is an important technology in Long Term Evolution Advanced (LTE-Advanced). Carrier aggregation means that user data can be simultaneously transmitted on multiple component carriers (Component Carriers, CCs), which is equivalent to increasing the user's transmission bandwidth. [0003] But at the same time, the carrier aggregation technology also brings many new radio resource management problems to the LTE-Advanced system. Since there are multiple component carriers in the system, and the channel characteristics of each component carrier are different, after a user selects a component carrier, uneven load of the component carriers will occur. Especially in the case of a heavy cell load, this phenomenon is more serious and...
