Abstract
Methods and devices of the invention relate to sending information over a wireless communications channel using an adaptive frame structure (AFS) having unequal error protection. Unequal error protection relates to a first data region of the frame being modulated with a first modulation and coding scheme (MCS) and a second data region of the frame being modulated with a different MCS typically with a higher modulation order. The first data region, modulated with a lower order MCS, may include critical data such as error checking and header/router information while the second region may include data payload for loss tolerant applications such as voice over Internet protocol (VoIP).
Claims19
A method for sending information over a wireless communications channel, the method comprising:
- generating a frame structure for transmission over the wireless communications channel, the frame structure having a first data region modulated with a first modulation and coding scheme (MCS) and a second data region modulated with a second MCS different than the first MCS, the second MCS selected based, at least in part, on an a type of application program relating to data in the second data region.
A method of receiving information in a wireless network, the method comprising:
- demodulating and decoding a received physical layer frame having a first region modulated with a first modulation and coding scheme (MCS) and a second region modulated with a second MCS different than the first MCS;
- and
- determining if any critical errors are present in the first region and if so, requesting the frame to be retransmitted.
A device to generate and send radio frames in a wireless network, the device comprising:
- a frame generator circuit to generate and digitally modulate a frame for transmission, the frame having a first region modulated with a first modulation and coding scheme (MCS) and a second region modulated with a second MCS different than the first MCS.
A device to generate and send radio frames in a wireless network, the device comprising:
- a frame generator circuit to generate and digitally modulate a frame for transmission, the frame having a first critical error protection region for data in which, if an uncorrectable error occurs upon the frame reception, the frame must be retransmitted and a second error protection region to carry data for loss tolerant data applications in which, if uncorrectable errors occur upon frame reception, retransmission of the frame is not required.
