Abstract
A means of power control on the reverse link of a CDMA network is disclosed. Specifically, the forward link from the base station to the subscriber unit is used to direct the subscriber unit to modify the output power radiated. The forward link consists of the forward packet data channel and the forward channel control channel. The forward packet data channel carriers the informational data to the subscriber unit, and the forward packet control channel includes carries of a power control setting. The forward channel is bi-phase modulated with the forward packet data channel transmitted in-phase and the forward packet control channel transmitted in quadrature.
Claims1
A method of communicating forward packet data and forward packet data control information over a forward link in a packet-switched CDMA network, comprising the steps of:
- carrying the packet data on the in-phase component of a quadrature-carrier signal;
- and
- carrying the packet data control information on the quadrature component of said quadrature-carrier signal.
