DEDICATED SINGLE STREAM PILOTS FOR UPLINK MULTI-USER MIMO |
| 摘要 |
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus allocates dedicated sets of pilot tones within symbols to a plurality of stations to enable per station phase drift tracking from symbol to symbol. Each station of the plurality of stations is allocated a dedicated set of pilot tones for transmitting dedicated single stream pilots to enable the apparatus to perform per station phase drift tracking from symbol to symbol. The apparatus transmits a frame to the plurality of stations. The frame includes information indicating the allocated and dedicated sets of pilot tones used for transmitting dedicated single stream pilots to enable per station phase drift tracking from symbol to symbol. |

1. A method of operating an access point, comprising:
allocating dedicated sets of pilot tones within symbols to a plurality of stations to enable per station phase drift tracking from symbol to symbol, wherein each station of the plurality of stations is allocated a dedicated set of pilot tones for transmitting dedicated single stream pilots to enable per station phase drift tracking from symbol to symbol, wherein phase drift tracking is different from channel estimation; and transmitting a frame to the plurality of stations, wherein the frame includes information indicating the allocated and dedicated sets of pilot tones used for transmitting dedicated single stream pilots to enable per station phase drift tracking from symbol to symbol, wherein phase drift tracking is different from channel estimation. |
