Abstract
A method for controlling a plurality of service units in a telecommunications system with a multi-carrier transmission scheme is provided. Specifically, in one embodiment, the method includes broadcasting control signals for the service units over a plurality of control channels distributed in a number of subbands of a frequency bandwidth. The method further includes identifying the service unit to use the control signal with an identifier.
Claims17
A method for controlling a plurality of service units in a telecommunication system with a multi-carrier transmission scheme, comprising the steps of:
- assigning an identifier to each service unit;
- assigning each service unit to a subband of a transmission channel of a narrow band transmission scheme, wherein each subband includes a control channel for receiving and transmitting control signals;
- broadcasting control signals for the service units over the control channels in a number of subbands;
- and
- identifying the service unit to use the control signal with the identifier.
A service unit for use with a communication system that transmits signals with a multi-carrier transmission scheme wherein a transmission channel is divided into a number of subbands each subband including a number of payload channels and a control channel, the service unit comprising:
- a modem that is tunable to receive telephony and control signals on a subband of a transmission channel;
- a controller circuit coupled to the modem to receive control signals over the control channel and to determine which control signals to use to control the operation of the modem;
- and
- interface circuits coupled to the controller for providing signals to a channel unit.
