Long wireless local area network (WLAN) packets with midambles

摘要

A preamble, a plurality of data segments of a data payload of a single data unit, and one or more midambles, each included between respective data segments, are generated. Data to be included in the data segments is processed, including at least one of: encoding all data payload bits of all segments as a whole, encoding data payload bits on a per segment basis, scrambling all data payload bits of all segments as a whole, scrambling data payload bits on a per segment basis, adding padding bits to only a last data segment, or adding padding bits to each data segment separately. The single data unit, including the preamble, the plurality of data segments and the one or more midambles, is caused to be transmitted. A network interface of a communication device may perform the generation and the data processing, and may cause the transmission of the single data unit.

主权项

1. A method for delivering a single data unit between a transmitter and a receiver over a communication channel, the method comprising:
generating a preamble of the single data unit; generating a plurality of data segments of a data payload of the single data unit; generating one or more midambles of the single data unit, each of the one or more midambles to be transmitted between respective data segments of the plurality of data segments; processing data to be included in the plurality of data segments of the data payload, including at least one of:
(i) encoding, as a whole, all data payload content bits included in the plurality of data segments, between which the one or more midambles are to be transmitted, and generating a set of tail bits to be transmitted after the last data segment,(ii) scrambling, as a whole, all data payload content bits included in the plurality of data segments, or(iii) padding, to correspond to an integer number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, by adding padding bits in a last data segment, from the plurality of data segments, to be transmitted, and not padding any of the other data segments; and causing the single data unit including the preamble, the plurality of data segments of the data payload, and the one or more midambles to be transmitted via at least one antenna over the communication channel.
