An information transmission method and a network device, the network device including a transceiver, a processor, and a non-transitory storage medium storing a computer program for execution by the processor. The computer program includes instructions to receive a first frame through the receiver, where an extended schedule element of the first frame has a field indicating communication between network devices is supported, and where the extended schedule element further has a source association identifier and a destination association identifier, and control the transceiver to transmit information to a first network device when both the first network device and the network device support communication between network devices, where a value of the source association identifier and a value of the destination association identifier are each 0.

Information transmission method and network device

Embodiments of this application provide an information transmission method and a network device. The method may include: listening, by a second network device, to a first frame sent by a first network device, where the first frame is used to indicate whether the first network device supports communication between network devices; and if both the first network device and the second network device support the communication between the network devices, transmitting, by the second network device, information with the first network device.

Embodiments of the present application provide a spatial reuse method. The method includes: receiving, by a first node in BSSa measurement request sent by a second node in BSSwhere one or more first service periods SPare allocated in the BSSone or more second service periods SPare allocated in the BSSand the measurement request is used to request to measure the one or more second service periods SPreceiving, by the first node in the BSSa measurement report of the second node in the BSSwhere the measurement report is a report of measuring the one or more first service periods SPand determining, by the first node in the BSSbased on the received measurement report, whether to allow spatial reuse of the one or more first service periods SPand the one or more second service periods SP
