FIELD: wireless communication.
SUBSTANCE: communication method carried out by an access point comprises steps of: competing for communication medium access for a first transmission capability (TXOP) covering a first duration; transmitting a first channel reservation message which reserves communication medium for a first TXOP; transmitting, during the first TXOP, scheduling the access terminal, providing uplink resources of access terminal for second TXOP, covering second duration; competing for communication medium access for a second TXOP; transmitting a second channel reservation message reserving a communication medium for a second TXOP; and receiving the uplink signaling from the access terminal through the provided uplink resources during the second TXOP.
EFFECT: technical result consists in improvement of robustness of signaling in a competition-based environment.
