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 based on a number of transmit chains per channel,
- wherein the number of transmit chains per channel is a half of a total number NTX of transmit chains,
- wherein the training field transmitted via first aggregated channel is generated based on a mapping matrix for the number of transmit chains per channel and one or more training basic sequences for space-time stream number 1 to NTX/2 and the training field transmitted via second aggregated channel is generated based on the mapping matrix for the number of transmit chains per channel and one or more training basic sequences for space-time stream number NTX/2+1 to NTX;
- and
- transmitting the signal comprising the training field to the second STA via 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 based on a number of transmit chains per channel,
- wherein the number of transmit chains per channel is a half of a total number NTX of transmit chains,
- wherein the training field transmitted via first aggregated channel is generated based on a mapping matrix for the number of transmit chains per channel and one or more training basic sequences for space-time stream number 1 to NTX/2 and the training field transmitted via second aggregated channel is generated based on the mapping matrix for the number of transmit chains per channel and one or more training basic sequences for space-time stream number NTX/2+1 to NTX;
- and
- transmit the signal comprising the training field to a different communication device via aggregated channels.
A communication device for receiving 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:
- receive the signal comprising a training field from a different communication device via aggregated channels,
- wherein the training field is generated based on a number of transmit chains per channel,
- wherein the number of transmit chains per channel is a half of a total number NTX of transmit chains,
- wherein the training field transmitted via first aggregated channel is generated based on a mapping matrix for the number of transmit chains per channel and one or more training basic sequences for space-time stream number 1 to NTX/2 and the training field transmitted via second aggregated channel is generated based on the mapping matrix for the number of transmit chains per channel and one or more training basic sequences for space-time stream number NTX/2+1 to NTX;
- and
- perform training operation based on the training field.
