METHOD FOR TRANSMITTING CONTROL INFORMATION AND APPARATUS FOR THE SAME |
摘要 |
Methods and devices for transmitting or receiving data in a wireless local area network are provided. The method in one embodiment includes transmitting, by a transmitter, a first long training field (LTF) to a receiver; transmitting, by the transmitter, a very high throughput (VHT)-SIG-A field to the receiver; transmitting, by a transmitter, a second LTF for multiple input multiple output (MIMO) channel estimation to the receiver; transmitting, by the transmitter, a VHT-SIG-B field to the receiver; and transmitting, by the transmitter, a data field to the receiver, wherein the first LTF, the VHT-SIG-A field, the second LTF, the VHT-SIG-B field and the data field are sequentially transmitted, and wherein the second LTF and the data field are mapped to at least one spatial stream based on a mapping matrix but the first LTF and the VHT SIG-A field are not mapped to the at least one spatial stream. |

1. A method for transmitting data in a wireless local area network, the method comprising:
transmitting, by a transmitter, a very high throughput (VHT)-SIG-A field in first subcarriers over first orthogonal frequency division multiplexing (OFDM) symbols to a receiver; transmitting, by the transmitter, a VHT-SIG-B field in second subcarriers over a single second OFDM symbols to the receiver; and transmitting, by the transmitter, a data field in third subcarriers to the receiver, wherein the VHT-SIG-A field, the VHT-SIG-B field and the data field are sequentially transmitted, wherein a number of the second subcarriers is greater than a number of the first subcarriers, and wherein
the VHT-SIG-B field is applied by a single column vector and the mapping matrix,the data field is applied by the mapping matrix, andthe VHT-SIG-A field is not applied by any of the single column vector and the mapping matrix. |
