Abstract

The invention discloses an estimation method for the user capacity of a multi-service large-scale MIMO system under a given service speed rate. The user capacity refers to the user number capable of being supported by the system, and the equivalent spectral bandwidth of each user is acquired according to the antenna number of a base station, the user number in the system, the channel state information of all the users in the system, the transmission speed rate of each user, the antenna number of each user, emitting power, noise power and the like so as to find out the relationship between the user capacity and spectral bandwidth of the system. The user capacity can be regulated through the antenna number of the base station, the antenna number of each user, the emitting power and the like, and this is good for an operator to perform frequency optimization to improve the spectral efficiency. The estimation method for the user capacity of the multi-service large-scale MIMO system solves the problems of unfair resource distribution and resource waste of the prior art due to being based on the maximum throughput capacity.

Description

technical field [0001] The invention relates to a method for estimating user capacity of a multi-service massive MIMO system under a given service rate condition, and belongs to the technical field of communication. Background technique [0002] The multi-service large-scale multiple transmitting antenna and multiple receiving antenna technology (Multiple-Input Multiple-Output, hereinafter referred to as: MIMO) system refers to a multi-user MIMO (MU-MIMO, Multi-user MIMO) system with enough base station antennas. The multi-user MIMO system refers to a base station sending information to multiple users at the same time in the same time slot and the same frequency band. Its biggest advantage is to improve spectrum utilization. Massive MIMO systems can carry more users. Capacity generally has the following three definitions: 1), rate, that is, the rate that the system bandwidth can provide; 2), throughput, that is, the sum of the transmission rates of all users in the system; ...
