    Abstract: Certain aspects of the present disclosure provide methods and apparatus for detecting ongoing transmissions and assessing channel state, based on midpacket detection. One example method generally includes receiving signals on a primary channel; detecting, based on the received signals, occurrence or non-occurrence of a first ongoing packet transmission on a primary channel; and generating at least one of a busy signal or an idle signal based on the detection. In this manner, collisions may be avoided.

    Abstract: 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.
