Method and apparatus for transceiving data in a MIMO system

摘要

The present invention relates to a method and apparatus for transceiving data. A method in which a transmitting terminal transmits data to a receiving terminal in a MIMO system according to one embodiment of the present invention comprises the following steps: generating a data field containing the data; generating a signal field containing information on the data field; generating a data frame containing the data field and the signal field; and transmitting the data frame to the receiving terminal. According to the present invention, an end of the frame being transmitted is accurately notified to the receiving terminal in a communication system in which the frame is transmitted using MIMO, thereby decoding the frame in a more efficient manner at the receiving terminal.

1. A method for wireless local area network using Multi-User Multiple Input Multiple Output (MU-MIMO) transmission, the method comprising,
generating a common signal field for all users including transmission duration information that indicates a duration of a Physical layer Protocol Data Unit (PPDU); generating a user dedicated Very High Throughout Signal-B (VHT SIG-B) field including length information indicating a length of a Physical layer Service Data Unit (PSDU) and information about a Modulation and Coding Scheme (MCS); generating VHT data including a service field and the PSDU; and transmitting the PPDU including the common signal field, the VHT SIG-B field and the VHT data over an operating channel, wherein the service field includes scrambler information and a cyclic redundancy check (CRC), the CRC being calculated over the VHT SIG-B field.
