Delay Management in Shared Baseband Deployments

摘要

A method of controlling radio link delay in a multi-standard wireless system having a first Radio Equipment Controller (REC) operating with a first radio standard interface and a second REC operating with a second radio standard interface is disclosed. A time delay between the first REC and a Radio Equipment (RE) and a time delay between the second REC and the RE is determined. When radio signal data from the first and second REC are received, they are stored into a memory. The stored radio signal data is then marked in accordance with the calculated time delay. The marked radio signal data from each REC is then multiplexed into a single radio signal timed according to a reference timing clock signal for transmission to the RE.
