SERVICE DATA TRANSMISSION METHOD AND SYSTEM |
摘要 |
<p>A data transmission method and system are disclosed. The method comprises: a sending station sends a radio frame and notifies group transmission time interval information; a group station receives the radio frame and acquires group transmission time interval information of a group to which the group station belongs; and the group station competes for a sending opportunity within the group transmission time interval of the group to which the group station belongs. In accordance with the scheme provided in embodiments of the disclosure, a sending station allocates specific group transmission time intervals (subsections) to stations of different groups, and in the case of a large number of users stations, user stations in different groups compete for channels within different time intervals, thereby avoiding the simultaneous or approximately simultaneous competition among a large number of users, reducing the probability of collisions and improving the utilization efficiency of wireless resources.</p> |
