System and method for uplink timing synchronization
First Claim
Patent Images
1. A method of uplink timing reference signal transmission in a user equipment comprising:
- receiving an uplink timing reference signal transmission instruction message;
determining a time interval to send a timing reference signal transmission in accordance with the uplink timing reference signal transmission instruction message;
evaluating if uplink data is to be sent in the time interval; and
if there is data to be sent, sending the data in the time interval, including sending a demodulation reference symbol in the time interval, wherein the timing reference signal transmission is not sent in the time interval, else sending the timing reference signal transmission in the time interval.
