18. A communication device comprising:
-
a receive chain and a transmit chain operating in a half-duplex mode to receive and transmit low duty cycle (LDC) messages using only overhead channels; and
a half-duplex controller coupled to the receive chain and the transmit chain to substantially free run a timing reference obtained during reception to allow a timing reference value to drift during transmission. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

34. A tangible storage medium including a computer program for operating a communication device in a half-duplex mode using only overhead channels, the program comprising executable instructions that cause a computer to:
-
substantially free run a timing reference obtained during reception to allow a timing reference value to drift during transmission; and
substantially freeze a power estimate obtained during said reception for use as a transmit power value during said transmission. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
