Low duty cycle half-duplex mode operation with communication device
First Claim
Patent Images
1. A method of operating a communication device comprising:
- communicating only on overhead channels;
communicating only in a half-duplex mode, wherein the communication device does not simultaneously send and receive messages; and
free running a timing reference, comprising a time tracking loop, obtained during reception to allow a timing reference value to drift during transmission.

18. A communication device comprising:
-
a receive chain and a transmit chain configured to; communicate only on overhead channels; communicate only in a half-duplex mode, wherein the communication device does not simultaneously send and receive messages; and receive and transmit low duty cycle (LDC) messages; and a half-duplex controller coupled to the receive chain and the transmit chain to free run a timing reference, comprising a time tracking loop, 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)
