Embodiment 1

[0095] Figure 7 It is a schematic diagram of the scheduling equipment scheduling the users of the three cells of the base station in the base station. As shown in the figure, the scheduling equipment is in the base station, and the base station includes 3 sectors, and centralized scheduling is performed in the base station.

[0096] Assumption: LTE-TDD (Time Division Duplex, Time Division Duplex) system with 10MHz bandwidth is divided into 50 basic scheduling units in frequency, named as PRB (physical resource block, physical resource block), and centralized downlink scheduling is considered. Then it can be implemented as follows.

[0097] 1) The scheduling device obtains the user information and resource information of the three cells to which it belongs through the data interface inside the base station. During implementation, it is also possible to directly read the information dynamic databases of the three cells to obtain the information.

[0098] Among them, the user ...

Embodiment 2

[0117] Figure 8 It is a schematic diagram for the scheduling device to schedule users in three cells belonging to different base stations in the base station. As shown in the figure, the scheduling device is in NodeB2, Cell 1 belongs to NodeB1, Cell 2 belongs to NodeB2, and Cell 3 belongs to NodeB3 .

[0118] Assumption: LTE-TDD system with 10MHz bandwidth is divided into 50 basic scheduling units in frequency, and centralized downlink scheduling is considered.

[0119] 1) The scheduling device obtains the user information and resource information of the cell 2 to which it belongs through the data interface inside the base station. And through the X2 interface, the user information and resource information of the cell 1 of the base station 1 and the cell 3 of the base station 3 are obtained.

[0120] Among them, the user information mainly includes: the user IDs to be scheduled in cells 1-3, the user's scheduling weight P, the user's home cell ID, and the user's expected co...

Abstract

The invention discloses a method for scheduling users in a plurality of communities and wireless access network equipment thereof; the method comprises the following steps that: schedulable resource information and information of users to be schedules in various communities are obtained; the resources used by the users to be scheduled in the communities are determined according to the resource information and the user information; the resources used by the users to be scheduled in the communities are notified to the corresponding communities; and the communities distribute the resources used by the users to be scheduled in the communities according to the notice. The invention realizes the centralized scheduling of the resources of various communities, can be used to assist in multi-pointtransmission, can effectively complete the coordinated scheduling of the communities, prevent resource impact and conflict, and improve the success rate of scheduling.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for scheduling users in multiple cells and wireless access network equipment. Background technique [0002] After the LTE (Long Term Evolution, long-term evolution) system adopts OFDM (Orthogonal Frequency Division Multiplex, Orthogonal Frequency Division Multiplex) technology, users are distinguished by orthogonal subcarriers, basically there is no interference between users in the cell, and the cell Interference becomes the main factor affecting the system capacity. Especially cell edge users are subject to strong interference from neighboring cells, resulting in poor spectrum efficiency and performance. In order to improve the performance of edge users, in the LTE system, ICIC (Inter-Cell Interference Coordinate, inter-cell interference coordination) technology is adopted to reduce inter-cell interference through static partial frequency reuse or semi-static inter...
