Method and apparatus of transmitting paging frame and wakeup frame

摘要

This document discloses a method and an apparatus for transmitting a paging frame and wakeup frame. The An AP comprises a transceiver receiving a paging frame from an STA; and a processor generating a wakeup frame for informing of existence of buffered data to be transmitted to the STA in response to the paging frame, where the paging frame includes a PLCP (Physical Layer Convergence Protocol) header and the PCLP header includes a waiting time field indicating a waiting time during which an STA is operated in the active mode to receive the wakeup frame; and the wakeup frame includes a PLCP header and the PLCP header includes a wakeup indication indicating the wakeup frame and a wakeup STA identification having information specifying the STA. Therefore, an STA can reduce power consumption wasted in the active mode.

1. A method for associating with an access point in a wireless local area network, the method comprising:
transmitting, by a station, a request frame to an access point (AP), the request frame including a physical layer header without a data field; determining, by the station, whether a response frame in response to the request frame is received from the AP before a waiting time expires; and if the response frame is received, transmitting, by the station to the AP, an association request frame to request an association with the AP, wherein the physical layer header includes a short training field, a long training field and a signal field, the signal field including frame type information and a cyclic redundancy check (CRC) for the signal field, and wherein the frame type information indicates the request frame includes no data field.
