First Claim
1. A method for sample synchronization comprising:
- receiving a return link (RL) timestamp from a radio frequency front end (RFFE);
receiving a system time second from a navigation and timing system;
generating a forward link (FL) timestamp based on the RL timestamp and the system time second; and
including the FL timestamp and the system time second in a time data.

Abstract
An apparatus and method for sample synchronization comprising receiving a return link (RL) timestamp from a radio frequency front end (RFFE); receiving a system time second from a navigation and timing system; generating a forward link (FL) timestamp based on the RL timestamp and the system time second; and including the FL timestamp and the system time second in a time data. In one aspect, the apparatus and method is used for RF control comprising storing gain information and gating control information in a memory; and performing one or more of the following: sending a first desired timestamp and the gain information to a radio frequency front end (RFFE); sending a second desired timestamp and a txEnable command to a transmit gating control; or sending a third desired timestamp and a rxEnable command to a receive gating control.
