Problems solved by technology

For a multi-base station wireless network, the characteristic of this proportional fairness algorithm for a single base station is that each base station selects a transmission user locally according to the historical service rate for all users, and has no information interaction with other base stations, so it is difficult to apply to a multi-base station network environment, its poor performance

Embodiment Construction

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0021] now refer to figure 2 , which shows the flow of steps in the method for scheduling a multi-base station multi-user network according to an embodiment of the present invention. The network system works in the mode of time division multiple access, that is, the information transmission between the base station and the user adopts the mode of time division multiplexing. For example, opportunistic time division multiple access, that is, the service time of each base station is divided into time slots of equal length, and each time s...

Abstract

The invention discloses a dispatching method of a multi-base-station and multi-user network, comprising the following steps of: (1) selecting a target user by each base station to carry out data transmission in a current time slot network according to the service probability of service users, and calculating the gradient component at each correspond user; (b) updating the service property of service users of the next time slot base station according to the gradient component; and (c) repeating the step (a) and the step (b) so as to execute the task scheduling of multiple base station servicesand multiple users in the network. The invention can realize the overall proportional fair scheduling and provide the service assurance for users on the throughput and the fairness.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a task scheduling method for data transmission under a network architecture in which multiple base stations serve multiple users at the same time. Background technique [0002] Under the network architecture where multiple base stations and multiple users transmit simultaneously, the structure is as follows figure 1 As shown, the information transmission between the base station and the user adopts the method of time division multiplexing, which can ensure that one base station can provide services for multiple user terminals. Due to the fading characteristics of the wireless channel, each base station has a certain probability to transmit information with its neighboring users in the mobile network. In order to make full use of the characteristics of wireless fading channels, the commonly used greedy scheduling strategy allows each base station to select the us...
