Abstract(in English) | The Multi-User Multiple Input Multiple Output (MU-MIMO) transmission technology has been standardized in the Wireless Local Area Network (WLAN) of IEEE802.11ac standard. MU-MIMO is will achieve very-high-speed transmission link rate. Moreover, this technology can transmit differential data to multiple users (terminals) concurrently by using Space Division Multiple Access (SDMA). However, if MU-MIMO is used in WLAN, there are some issues. One of issues is delay of data generation time, because data of multi user are not generated concurrently. Second of issues is delay of channel estimation time. These delay time are overheads in transmission procedure, and transmission efficiency will be degraded. In order to resolve these issues, channel estimation processing is immediately performed when initial data was generated. The synchronous random access scheme is proposed in order to decrease overhead time. In this paper, band occupancy rate was evaluated of conventional and proposed scheme, and examined the scope of the proposed scheme. |
