[0076] In the first embodiment, the space division multiple access method under the super cell includes the following steps:

[0077] Step S11, obtaining the CP activation set of each unscheduled user;

[0078] Specifically, for each unscheduled user under the super cell, the base station obtains all CPs corresponding to the unscheduled user. The signal values ​​of the unscheduled user received on all CPs corresponding to the unscheduled user are different. Among all the CPs corresponding to the unscheduled user, some CPs have high performance in communicating with the unscheduled user, while Some CPs have low performance in communicating with the unscheduled user, and the CP with high performance in communicating with the unscheduled user is determined as the active CP of the unscheduled user; otherwise, it is determined as the inactive CP of the unscheduled user. The determined set of activated CPs of the unscheduled user is used as an activated set of CPs of the unschedule...

Abstract

The invention discloses a super-cell SDMA (Spatial Division Multiple Access) method, and the method comprises the steps: firstly obtaining a CP excitation set of each user which is not dispatched; secondly determining the users with no intersection between the CP excitation sets of the users which are not dispatched as the SDMA users; and finally distributing the same time frequency resource or different time frequency resources to the SDMA users. The invention also discloses a super-cell SDMA base station. The method provided by the invention improves the SDMA probability and resource distribution flexibility.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a space division multiple access method and a base station thereof under a super cell. Background technique [0002] With the continuous evolution of communication technology, the LTE (Long Term Evolution, Long Term Evolution) system has been extensively studied and gradually applied to commercial networks. The LTE system is based on core technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple Output) to provide users with higher data transmission rates, lower transmission delays and more Excellent service quality. A super cell (Super-Cell) is a type of cell in the LTE system, and each super cell is composed of multiple CPs (Cell-Portions, sub-cell units). Each CP shares the resources of the super cell, including the cell ID (CellID), time domain resources, frequency domain resources, etc., and multiple CPs can jointly process...
