Problems solved by technology
[0012] However, when the distribution of user equipment is uneven, the time-frequency resources allocated to user equipment in the sparse area of user equipment will be higher than the average So that it will be far greater than the amount of time-frequency resources required by the user equipment itself, resulting in a waste of time-frequency resources; and the time-frequency resources allocated to user equipment in densely populated areas will be lower than the average So that it will be far less than the amount of time-frequency resources required by the user equipment itself, reducing the service quality of this part of the user equipment
[0013] In order to avoid the uneven allocation of time-frequency resources, it is urgent to provide a beam allocation method and device for millimeter wave communication systems.

Embodiment Construction
[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.
[0034] like figure 2 As shown, an embodiment of the present invention provides a beam allocation method for a millimeter wave communication system, including:
[0035]S1, if it is determined that the sum of the number of user equipments served by the first beam and the second beam generated by the base station is less than the first preset number of user equipments, combine the first beam and the second beam into one beam, and serving the user equipment corresponding to the first beam and the second beam through the combined beam, where the first beam and the second beam are two adjacent beams;
[0036] S2, if it is determined that the number of user equipments served by the third beam gener...

The invention provides a beam distribution method and device of the millimeter wave communication system.Decomposition and improve the time -frequency resources assigned by user equipment in the area; because there are both beam decomposition and the merger of beams, the total number of beams will not change much.The time -frequency resources will not change much, ensuring that the time -frequency resources allocated by each user device are closer to the average, thereby increasing the fairness of resource distribution.
Description
technical field [0001] The present invention relates to the field of communication technologies, and more particularly, to a beam allocation method and device of a millimeter wave communication system. Background technique [0002] With the development of economy and society, people's demand for communication speed is showing an exponential growth trend. Millimeter wave is regarded as the key technology of next-generation wireless communication system (5G) due to its abundant spectrum resources. The wavelength of the millimeter-wave band is short, and according to the antenna theory, the antenna size is also small, and a large number of antennas can be integrated in a small area, which is convenient for compensating for the high transmission loss of the millimeter-wave band through beamforming technology. [0003] Consider a millimeter-wave communication system that includes a base station and a cell covered by the base station. The cells covered by the base station 10 are...
