Abstract
A system and method for a hybrid 1× evolution data only (1×EV-DO) forward link are provided. The data channels of a 1×EV-DO forward link are transmitted using Orthogonal Frequency Division Multiplexing (OFDM), while pilot and Medium Access Control (MAC) channels are transmitted using Code Division Multiple Access (CDMA). The pilot and MAC channels can use CDMA in one time slot and OFDM in another time slot.
Claims24
A method for transmitting a forward link from a base station to a mobile station, the method comprising the acts of:
- transmitting control channels using Code Division Multiple Access (CDMA);
- and
- transmitting data channels using Orthogonal Frequency Division Multiplexing (OFDM).
A computer-readable medium encoded with a computer program for transmitting a forward link from a base station to a mobile station, the computer program comprising instructions for:
- transmitting control channels using Code Division Multiple Access (CDMA);
- and
- transmitting data channels using Orthogonal Frequency Division Multiplexing (OFDM).
A base station processor, comprising:
- logic for controlling transmission of control channels using Code Division Multiple Access (CDMA);
- and
- logic for controlling transmission of data channels using Orthogonal Frequency Division Multiplexing (OFDM).
A wireless communication device, comprising:
- a transmitter which transmits controls channels and data channels;
- and
- a processor including logic for controlling transmission of the control channels and the data channels, wherein the control channels are transmitted using Code Division Multiple Access (CDMA) and the data channels are transmitted using Orthogonal Frequency Division Multiplexing (OFDM).
