FIELD: broadband wireless access communication system, in particular, method for controlling inactive mode and active mode in communication system for broadband wireless access with orthogonal frequency division of channels.
SUBSTANCE: a communication system for broadband wireless access is claimed, having inactive mode, where no data is present which is subject to transmission or receipt by client station at/from base station, and active mode, where data is present, which is subject to transmission or receipt by client station at/from base station, while client station sets next inactive mode after inactive interval between starting time of inactive mode and starting time of active mode reaches given value of maximal window. Client station receives information exchange indication flow, denoting absence of data, subject to transmission from base station after starting time of active mode; transfers message with request of inactive mode to base station; receives a message of response to a message with inactive mode request from base station; and then functions in next inactive mode.
EFFECT: increased efficiency of inactive interval setup.
