Abstract
Apparatus, and an associated method, for facilitating operation of a radio communication system that provides for multi rate data communications, such as a CDMA 2000 system that provides for 1×EV-DV communication services. A supplemental pilot, or control, signal generator embodied at a mobile station generates a supplemental pilot, or control, signal that is sent on a newly defined supplemental pilot, or control, channel. As the data rates of data communicated upon a reverse supplemental channel changes, corresponding changes are made to the power level of the reverse supplemental pilot, or control, signal.
Claims18
A method comprising:
- receiving a pilot signal on a reverse pilot channel and a supplemental pilot signal on a reverse supplemental pilot channel;
- receiving data on a reverse data channel, wherein a power level of the received supplemental pilot signal varies based on variations in a data rate on the reverse data channel;
- and
- demodulating the reverse data channel in a coherent manner based on the pilot signal and the supplemental pilot signal.
An apparatus comprising:
- a receiver circuit configured to receive a reverse pilot channel including a pilot signal, a reverse supplemental pilot channel including a supplemental pilot signal, and data on a reverse data channel including modulated data, wherein a power level of the supplemental pilot signal is adjusted based on variations in a data rate on the reverse data channel;
- and
- a demodulator configured to demodulate the data on the reverse data channel in a coherent manner based on the pilot signal and the supplemental pilot signal.
