The invention provides a mechanism for reducing residual frequency differences in distributed MIMO using a slave trigger, and increasing synchronization precision between APs. The communication device, which constitutes a wireless network by cooperating with another communication device, has a transmission unit for transmitting a frame for synchronization to the other communication device to cooperate with the other communication device. The transmission unit includes: a setting unit that sets a value exceeding 4 as a repetition number for an EHT Long Training Field (EHT-LTF) in a preset position of an EHT Signal Field (EHT-SIG-A) of a frame for synchronization; and a generation unit that generates a frame for synchronization, the frame including EHT-LTFs whose quantity is the set repetition number. The transmission unit transmits the generated frame to the other communication device.
A master access point (AP) which constitutes a wireless network by cooperating with a slave AP, the master AP comprising:
A method for controlling a master access point (AP) which constitutes a wireless network by cooperating with a slave AP, the method comprising:
A non-transitory computer-readable storage medium storing a computer program that is read and executed by a processor in a master access point (AP) that constitutes a wireless network by cooperating with a slave AP, wherein the program causes the master AP to execute:
A slave access point (AP) which performs a wireless communication by cooperating with a master AP, the slave AP comprising:
A method for controlling a slave access point (AP) which constitutes a wireless network by cooperating with a master AP, the method comprising:
A non-transitory computer-readable storage medium storing a computer program that is read and executed by a processor in a slave access point (AP) that constitutes a wireless network by cooperating with a master AP, wherein the program causes the slave AP to execute:
