COMMUNICATION DEVICE, COMMUNICATION METHOD, COMPUTER PROGRAM, AND COMMUNICATION SYSTEM

摘要

Appropriate communication operation is performed by employing space division multiple access in which wireless resources on a space axis are shared by a plurality of users. Frame exchange is performed between an access point and terminals whereby the access point estimates delay times of the terminals and notifies the terminals of information on the delay times and the terminals perform uplink frame transmission to the access point taking a difference among the delay times into consideration. Interference among users may be reduced in the access point and throughput of a system which performs the space division multiple access is improved.
