Wireless communication system and wireless communication method

摘要

The present invention relates to a radio communications system and a radio communications method, and an object of the invention is to readily reduce the occurrence of collisions of contention channels. In order to achieve the object, radio resources are assigned in different orders between one radio communication and another one radio communication.

主权项

1. A radio communications system comprising:
a plurality of radio communications devices, wherein said plurality of radio communications devices are configured to perform a plurality of radio communications by using a plurality of radio resources between said plurality of radio communications devices, said plurality of radio resources correspond to a plurality of subcarriers that are assigned in different orders between one of said plurality of radio communications and another one of said plurality of radio communications, such that the plurality of radio communication devices are classified into different user groups having different priorities assigned to the plurality of subcarriers in a way that none of the user groups have a same priority assigned to a same subcarrier and radio communication devices of different user groups communicate with a same base station, and said priority is a priority in assigning a subcarrier to the radio communications.
