Abstract
A method is described for providing extended wireless coverage. The method includes transmitting, by a station (STA), at least a first frame including one or more short training fields (STFs) and a legacy STF, each of the one or more STFs carrying a sequence of symbols that is orthogonal to a sequence of symbols carried by the legacy STF.
Claims21
A method for wireless communication, the method comprising:
- transmitting, by a wireless transmission device, a frame including a legacy short training field (STF), one or more STFs, a legacy channel estimation field, and one or more channel estimation fields, each of the one or more STFs being orthogonal to the legacy STF based on cross-correlation between the legacy STF and the one or more STFs, the legacy STF and the one or more STFs being used for at least one of automatic gain control and synchronization, wherein a number of the one or more STFs and a number of the one or more channel estimation fields are dynamically configured according to changing transmission conditions, the changing transmission conditions including at least one of signal amplitude, path loss, and channel attenuation, and wherein the legacy STF is directed to a first communication protocol and the one or more STFs are directed to a second communication protocol in order to allow for communication under either protocol or allow for functionality using different protocols.
A method for wireless communication, the method comprising:
- receiving, by a wireless receiving device, a frame including a legacy short training field (STF), one or more STFS, a legacy channel estimation field, and one or more channel estimation fields, each of the one or more STFs being orthogonal to the legacy STF based on cross-correlation between the legacy STF and the one or more STFs, the legacy STF and the one or more STFS being used for at least one of automatic gain control and synchronization, wherein a number of the one or more STFs and a number of the one or more channel estimation fields are dynamically configured according to changing transmission conditions, the changing transmission conditions including at least one of signal amplitude, path loss, and channel attenuation, and wherein the legacy STF is directed to a first communication protocol and the one or more STFs are directed to a second communication protocol in order to allow for communication under either protocol or allow for functionality using different protocols.
A device comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- transmit a frame including a legacy short training field (STF), one or more STFs, a legacy channel estimation field, and one or more channel estimation fields, each of the one or more STFs being orthogonal to the legacy STF based on cross-correlation between the legacy STF and the one or more STFs, the legacy STF and the one or more STFs being used for at least one of automatic gain control and synchronization, wherein a number of the one or more STFs and a number of the one or more channel estimation fields are dynamically configured according to changing transmission conditions, the changing transmission conditions including at least one of signal amplitude, path loss, and channel attenuation, and wherein the legacy STF is directed to a first communication protocol and the one or more STFs are directed to a second communication protocol in order to allow for communication under either protocol or allow for functionality using different protocols.
