RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18034055 titled 'RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION SYSTEM
Simplified Explanation
- The present invention is related to a wireless LAN communication system. - The invention aims to improve frequency efficiency in the system. - It proposes configuring a different primary channel for uplink frame transmission and downlink frame transmission. - The system supports frame transmission and reception using a broadband frequency. - The system includes various types of terminal apparatuses, such as power-saving terminals, legacy terminals, and low-spec terminals. - The ratio of terminal apparatuses using the entire bandwidth may not be high during a transition stage. - Concentration of radio frames around the primary channel can result in idle radio channels that decrease frequency efficiency.
Original Abstract Submitted
According to an aspect of the present invention, in a wireless LAN communication system, a primary channel to be used for uplink frame transmission is configured to be different from a primary channel to be used for downlink frame transmission, so that the frequency efficiency can be improved. In a wireless LAN communication system capable of frame transmission and/or reception using a broadband frequency such as a 320 MHz bandwidth, terminal apparatuses connected to an access point apparatus include terminals that perform power saving operations, legacy terminals, and low-spec terminals, and it is conceivable that a ratio of terminal apparatuses that perform frame transmission and/or reception using the entire bandwidth is not so high particularly in a transition stage. In this case, radio frames are concentrated particularly around the primary channel in the entire band, and a radio channel that cannot be used for frame transmission and/or reception and becomes idle is generated, resulting in decrease in frequency efficiency.
