Abstract
A method of transmitting and receiving signals in a wireless local area network (WLAN) system and a device for the same are provided. More particularly, there are provided a method and a device for the same in which a station operating in an orthogonal frequency division multiplexing (OFDM) mode transmits and receives signals through two aggregated channels.
Claims15
A method for transmitting, by a first station (STA), a signal to a second STA in a wireless local area network (WLAN), the method comprising:
- generating a first modulation symbol value for a first aggregated channel and a second modulation symbol value for a second aggregated channel, wherein the first modulation symbol value is modulated based on each pair of bits included in first input encoded bits of a first space-time stream, wherein the second modulation symbol value is modulated based on each pair of bits included in second input encoded bits of a second space-time stream, wherein the first modulation symbol value is a conjugate value of the second modulation symbol value, wherein the first aggregated channel and the second aggregated channel are included in aggregated channels;
- and
- transmitting the signal including the first modulation symbol value and the second modulation symbol value to the second STA through the aggregated channels.
A method for receiving, by a first station (STA), a signal from a second STA in a wireless local area network (WLAN) system, the method comprising:
- receiving the signal through aggregated channels comprising a first aggregated channel and a second aggregated channel;
- and
- decoding the signal based on a first modulation symbol value and a second modulation symbol value,
- wherein the first modulation symbol value is generated for the first aggregated channel,
- wherein the first modulation symbol value is generated for the second aggregated channel,
- wherein the first modulation symbol value is modulated based on each pair of bits included in first input encoded bits of a first space-time stream,
- wherein the second modulation symbol value is modulated based on each pair of bits included in second input encoded bits of a second space-time stream,
- wherein the first modulation symbol value is a conjugate value of the second modulation symbol value, and
- wherein the signal includes the first modulation symbol value and the second modulation symbol value.
A station device for transmitting a signal in a wireless local area network (WLAN) system, the station device comprising:
- a transceiver having at least one radio frequency (RF) chain and configured to transmit and receive signals to and from another station device;
- and
- a processor connected to the transceiver to process signals transmitted and received to and from the another station device,
- wherein the processor is configured to:
- generate a first modulation symbol value and a conjugated value for a first aggregated channel and a second modulation symbol value for a second aggregated channel, wherein the first modulation symbol value is modulated based on each pair of bits included in first input encoded bits of a first space-time stream, wherein the second modulation symbol value is modulated based on each pair of bits included in second input encoded bits of a second space-time stream, wherein the first modulation symbol value is a conjugate value of the second modulation symbol value, wherein the first aggregated channel and the second aggregated channel are included in aggregated channels;
- and
- transmit the signal including the first modulation symbol value and the second modulation symbol value to the second STA through the aggregated channels.
