Method, device and system for determining remote access units

Abstract

The embodiment of the invention relates to a method, a device and a system for determining remote access units, wherein the method for determining remote access units comprises the following steps: acquiring maximum throughput which can be provided for a mobile terminal by a remote access unit of a source cell, the maximum throughput which can be provided for the mobile terminal by the remote access unit of a target cell, as well as the maximum throughput which can be provided for the mobile terminal by the combination of the remote access units of the source cell and the target cell respectively; and determining the remote access unit which provides service for the cell switching of the mobile terminal according to switching protection threshold and the acquired maximum throughput which can be provided for the mobile terminal. Based on the principle of the maximum throughput, the method, the device and the system for determining remote access units can enable the mobile terminal to have the maximum throughput while the mobile terminal is switched between adjacent DAS cells, and enable the mobile terminal to be smoothly switched between the adjacent cells by setting the reasonable switching protection threshold.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method, device and system for determining a remote access unit. Background technique [0002] With the rapid development of communication technology, traditional multiple access communication methods such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), and Code Division Multiple Access (CDMA) can no longer meet the high demands of future mobile communications. Requirements for spectral efficiency; for these multiple access methods, if you want to obtain higher spectral efficiency, the only way is to increase the transmit power of the system transmitter. The interference will increase, which in turn reduces the spectral efficiency of the system. In order to improve the spectral efficiency of the system under the same transmission power, a technology called Multiple Input Multiple Output (MIMO) has been d...
