Abstract
Certain aspects of the present disclosure relate to a method for generating a frame structure that can be used with multiple transmission schemes, such as a Single Carrier (SC) transmission scheme and an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme.
Claims43
A method for wireless communications, comprising:
- generating a preamble and a data payload;
- and
- transmitting a frame comprising the preamble and the data payload, wherein the preamble is transmitted according to a single carrier (SC) transmission scheme at a first chip rate and the data payload is transmitted according to an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme at a second chip rate different from the first chip rate.
An apparatus for wireless communications, comprising:
- a generator configured to generate a preamble and a data payload;
- and
- a transmitter configured to transmit a frame comprising the preamble and the data payload, wherein the preamble is transmitted according to a single carrier (SC) transmission scheme at a first chip rate and the data payload is transmitted according to an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme at a second chip rate different from the first chip rate.
An apparatus for wireless communications, comprising:
- means for generating a preamble and a data payload;
- and
- means for transmitting a frame comprising the preamble and the data payload, wherein the preamble is transmitted according to a single carrier (SC) transmission scheme at a first chip rate and the data payload is transmitted according to an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme at a second chip rate different from the first chip rate.
A computer-program product for wireless communications, comprising a computer-readable medium comprising instructions executable to:
- generate a preamble and a data payload;
- and
- transmit a frame comprising the preamble and the data payload, wherein the preamble is transmitted according to a single carrier (SC) transmission scheme at a first chip rate and the data payload is transmitted according to an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme at a second chip rate different from the first chip rate.
A wireless node, comprising:
- at least one antenna;
- a generator configured to generate a preamble and a data payload;
- and
- a transmitter configured to transmit via the at least one antenna a frame comprising the preamble and the data payload, wherein the preamble is transmitted according to a single carrier (SC) transmission scheme at a first chip rate and the data payload is transmitted according to an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme at a second chip rate different from the first chip rate.
