Abstract

Disclosed are an antenna allocation method and device. The method comprises: obtaining location information of a terminal; according to the location information, determining a reference number of antennae within a transmitting end, the antennae being used for sending data to the terminal; determining whether a transmission performance difference value is less than a preset transmission performance threshold value; when the transmission performance difference value is not less than the preset transmission performance threshold value, increasing the reference number, and returning to execute the step of determining whether the transmission performance difference value is less than the preset transmission performance threshold value, until the transmission performance difference value is less than the preset transmission performance threshold value; when the transmission performance difference value is less than the preset transmission performance threshold value, determining the increased reference number to be a target number; in the transmitting end, allocating the target number of antennae to the terminal. The present antenna allocation method reduces channel estimation workload when precoding, and, by decreasing the number of antennae allocated to a terminal, also reduces operational complexity when precoding, thereby improving system performance.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an antenna distribution method and device. Background technique [0002] With the rapid development of communication technology, users' increasing data rate requirements and scarce spectrum resources have become a huge challenge for wireless communication. The next-generation mobile communication system needs to achieve higher spectrum utilization, so as to provide a higher data rate service for a large number of users. In the next generation of cellular wireless communication technology, increasing the number of antennas on the base station side is widely recognized by the industry, especially when the number of antennas is large, there are many antenna characteristics that can be used, for example: the correlation between the channels formed by different users and the base station Smaller, small-scale fading and thermal noise can be averaged out and so on. Un...
