Abstract
Apparatus, and associated method, for facilitating reverse link scheduling in a CDMA 2000 communication system (FIG. 1, 10) that provides for high data rate communication services, such as 1xEV-DV communication services. Power control bits (FIG. 1, 46) used to perform power control on the reverse link are punctured with rate grant control bits and HARQ indications. A power control bit puncturer (FIG. 1, 48) punctures the power control bits with the rate grant control bits and HARQ indications. Physical layer signaling is thereby provided without the need to define additional control channels operations.
Claims20
In a radio communication system having a first communication station operable at least to send power control commands upon at least a power control channel to at least a second communication station, the power control commands used at the second communication station to control an operational parameter associated with a power level at which data subsequently to be communicated therefrom is sent, an improvement of apparatus for facilitating control of selected operation of the second communication station, said apparatus comprising:
- a power control command puncturer adapted to receive indications of an other-than-power control command, said power control command puncturer for puncturing the power control commands sent upon the at least the power control subchannel with the other-than-power-control command.
In a method of communicating in a radio communication system having a first communication station operable at least to send power control commands upon at least a power control channel to at least a second communication station, the power control commands used at the second communication station to control an operational parameter associated with a power level at which data subsequently to be communicated therefrom is sent, an improvement of a method for facilitating control of selected operation of the second communication station, said method comprising:
- obtaining indications of an other-than-power-control command associated with the selected operation;
- and
- puncturing the power control commands sent upon the at least the power control channel with the other-than-power-control command.
