Claims17
A method for transmitting a signal by a first station (STA) to a second STA based on a channel aggregation transmission in a wireless local access network (WLAN) system, the method comprising:
- generating a training field for aggregated channels in which a first channel and a second channel are aggregated,
- wherein a number of transmit chains for the first channel and a number of transmit chains for the second channel are a half of a total number NTX of transmit chains,
- wherein the training field transmitted via the first channel is generated based on a first mapping matrix, wherein the first mapping matrix includes training basic sequences for the transmit chains for the first channel, wherein the transmit chains for the first channel is related to space-time stream number 1 to NTX/2,
- wherein the training field transmitted via the second channel is generated based on a second mapping matrix, wherein the second mapping matrix includes training basic sequences for the transmit chains for the second channel, wherein the transmit chains for the second channel is related to space-time stream number NTX/2+1 to NTX;
- and
- transmitting the signal comprising the training field to the second STA via the aggregated channels.
A communication device for transmitting a signal based on a channel aggregation transmission in a wireless local access network (WLAN) system, the communication device comprising:
- a memory;
- and
- a processor operably coupled to the memory and configured to:
- generate a training field for aggregated channels in which a first channel and a second channel are aggregated,
- wherein a number of transmit chains for the first channel and a number of transmit chains for the second channel are a half of a total number NTX of transmit chains,
- wherein the training field transmitted via the first channel is generated based on a first mapping matrix, wherein the first mapping matrix includes training basic sequences for the transmit chains for the first channel, wherein the transmit chains for the first channel is related to space-time stream number 1 to NTX/2, and
- wherein the training field transmitted via the second channel is generated based on a second mapping matrix, wherein the second mapping matrix includes training basic sequences for the transmit chains for the second channel, wherein the transmit chains for the second channel is related to space-time stream number NTX/2+1 to NTX;
- and
- transmit the signal comprising the training field to a different communication device via the aggregated channels.
