Title:
無線ローカルエリアネットワークにおいてシグナリングを送受信するための方法および装置
Document Type and Number:
Japanese Patent JP6837978
Kind Code:
B2
Abstract:
Embodiments of the present invention provide a method and an apparatus for sending and receiving signaling in a wireless local area network, so as to resolve a problem that there is no orthogonal frequency division multiple access (OFDMA)-based design solution for common signaling in a wireless local area network (WLAN) at present. The method includes: generating, by an access point (AP), signaling, where the signaling includes an AP identifier (ID) field, a bandwidth (BW) field, a guard interval (GI) field, a cyclic redundancy check (CRC) field, and a tail (Tail) field, the AP ID field is used to indicate an ID of the AP, the BW field is used to indicate bandwidth required for data transmission subsequent to the signaling, the GI is used to indicate a length of a cyclic prefix (CP) required for data transmission subsequent to the signaling, the CRC field is used to guard a field before the CRC field in the signaling, and the Tail field is used to empty an encoder and a decoder, where the CRC field and the Tail field are the last two fields of the signaling; and sending, by the AP, the signaling. The present invention is applicable to the communications field.
