Abstract

The invention relates to a pilot frequency distribution method and device, computer equipment and a computer readable storage medium. The pilot frequency distribution method comprises: dividing all users of a target cell into a first type of users and a second type of users; determining a target user distance factor value according to the distance value between the target user and the central basestation, the first type pilot multiplexing degree, the second type pilot multiplexing degree, the cell radius and the path loss index; determining a first type of cost function; determining a secondtype of cost function; determining categories of all users in the target cell; obtaining the number of the first type of users and the number of the second type of users; obtaining a first type of spectral efficiency and a second type of spectral efficiency; determining the spectral efficiency of the target cell user; and determining the orthogonal pilot frequency number of the target cell. According to the pilot frequency distribution method and device, the computer equipment and the computer readable storage medium provided by the invention, the number of orthogonal pilot frequencies required by the system can be effectively reduced, and the spectral efficiency of the central base station can be kept not to be reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, and particularly relates to a pilot distribution method and device, computer equipment, and a computer-readable storage medium. Background technique [0002] In the wireless communication of the MIMO system, to accurately obtain channel state information, it is necessary to use a pilot frequency allocation method to estimate channel parameters. Pilot allocation generally requires that the pilots between users are orthogonal to each other, but because the channel coherence time is very short, the number of orthogonal pilots that the system can use is very limited, which results in the lack of mutually orthogonal pilot training sequences in the system. The number is far from meeting the requirements of the system to accurately obtain channel state information. [0003] Based on this, using non-orthogonal pilot sequences between different cells can effectively reduce the number of orth...
