Problems solved by technology

[0003] A SDMA (Spatial Division Multiplex Access, Space Division Multiple Access) method under a super cell in the prior art, by measuring the mutual interference between the master user and the slave user, only when the master user and the slave user When the mutual interference is less than a certain threshold value, SDMA can be performed. The matching rate between the master tuner user and the slave tuner user meeting this condition is not high, so the probability that the user can perform SDMA is low.
Moreover, in the existing SDMA method, the master user and the slave user must occupy exactly the same time-frequency resources, which limits the flexibility of resource allocation.

Abstract

The invention provides a space division multiple access method under a super cell. The method comprises the following steps: acquiring a sub-cell unit CP activation set of a terminal; dividing terminals with the CP number of 1 in the CP activation set into empty groups; grouping the terminals of which the CP number in the CP activation set is greater than 1 into frequency groups; controlling the terminals in the empty packets to be scheduled by the CPs to which the terminals belong, and scheduling the terminals in the frequency packets. The invention further provides a space division multiple access device under the super cell, electronic equipment and a computer readable medium.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of the Internet, and in particular, to a method and device for spatial division multiple access under a super cell, electronic equipment, and a computer-readable medium. Background technique [0002] With the continuous evolution of communication technologies, 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 and lower transmission times. latency and better quality of service. 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 a cell ID (Cell ID), time domain ...
