Abstract

The invention provides a coordination enhanced transmission method for beam communication, relating to the technical field of wireless communication. The method is as follows: a station distributes frequency bandwidth resources required by UE (User Equipment) in a non-beam overlapping area to the UE in the non-beam overlapping area by employing OFDM (Orthogonal Frequency Division Multiplexing) according to transmission requirements of the UE in the non-beam overlapping area, and distributes the rest system frequency bandwidth resources to the UE in a beam edge overlapping area; a sending end modulates data to distributed frequency bandwidths for data transmission; a receiving end carries out data demodulation on the corresponding frequency bandwidths; and thus, the data transmission is finished. According to the coordination enhanced transmission method, under a single-beam service multiple-UE service mode, the problems of low service efficiency and resource waste of the single-beam service single-UE service mode are avoided. With multi-beam coordination, while the communication requirements of the UE in the non-beam overlapping area are guaranteed, the performance of the UE in the beam overlapping area is improved; a multi-beam coordinated service is carried out in the single station, so the coordination among the beams is easy and the implementation is simple.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a cooperative enhanced transmission method in beam communication. Background technique [0002] The research scenario of the present invention is a single-site (BS or AP) beam communication scenario, where a single site is a base station (BS) (BaseStation) or a wireless access point AP (Wireless Access Point). ability to communicate. [0003] 5G is a new generation of mobile communication system developed for the needs of mobile communication after 2020. According to the development law of mobile communication, 5G will have ultra-high spectrum utilization and energy efficiency, and it will be an order of magnitude or higher than 4G mobile communication in terms of transmission rate and resource utilization. Its wireless coverage performance, transmission delay, system Security and user experience will also be significantly improved. Massive-MIMO (Multiple-Input ...
