Wireless terminal device

Abstract

The present invention provides access points, wireless terminal devices, and communication systems that suppress delays in wirelessly transmitted traffic. [Solution] In a communication system, an access point AP includes a first radio signal processing unit and a first management unit. The first management unit uses the first radio signal processing unit to establish a first link with a first radio terminal device STA1 and a second link with a second radio terminal device STA2, sets a service period SP in a first cycle, provides the first radio terminal device with an opportunity to transmit data and sets a transmission suppression period QI within the service period to suppress or prohibit data transmission by the second radio terminal device, and sets a transmission suppression period RP outside the service period to suppress or prohibit data transmission by the first radio terminal device.

Claims

[Claim 1] A wireless communication terminal that communicates with an access point in accordance with the IEEE 802.11 standard, A wireless signal processing unit that establishes a link with the aforementioned access point, The system includes a management unit that acquires the communication parameters to be used by the wireless communication terminal, The aforementioned management department, The access point receives, as communication parameters, a first access parameter used for a first wireless communication terminal that does not perform communication based on trigger frames received during the Target Wake Time (TWT) service period, a second access parameter used for a second wireless communication terminal that performs communication based on trigger frames received during the TWT service period, information on the TWT service period for which communication using TWT is performed, and information indicating a predetermined period length for which the second access parameter should be used. In the TWT service period, if, based on the transmission of data based on the trigger frame, other data is to be transmitted within the predetermined period length after the transmission of said data, the second access parameter is used to transmit the data. Based on the fact that no data based on the trigger frame was transmitted during the TWT service period, the data is transmitted using the first access parameter. Wireless terminal device.
