Method of handing-off a remote unit based on overhead information start times

A method of handing-off a remote unit from a first base station to a second base station, the method comprising:

• synchronizing overhead information between the first base station and the second base station to determine an overhead information start time;
• communicating by the remote unit with the first base station;
• determining a need to hand-off the remote unit to the second base station;
• determining a transition time, the transition time being the time it takes the remote unit to transition from the first base station to the second base station;
• and
• handing-off the remote unit to the second base station based upon the overhead information start time and the transition time.

A method of handing-off a remote unit from a first base station to a second base station having a primary channel and a secondary channel, the method comprising:

• transmitting a primary channel overhead information start time of the primary channel at a first time;
• transmitting a secondary channel overhead information start time of the secondary channel at a second time;
• communicating by the remote unit with the first base station;
• determining a need to hand-off the remote unit to the second base station;
• determining a transition time, the transition time being the time it takes the remote unit to transition from the primary channel to the secondary channel;
• handing-off the remote unit to the second base station based upon the primary channel overhead information start time and the transition time;
• and
• transitioning the remote unit from the primary channel in the second base station to a secondary channel in the second base station based on overhead information transmitted by the primary channel.

A method of handing-off a remote unit from a first base station to a second base station, the method comprising:

• time-aligning overhead information transmitted from a first base station and a second base station, the time-aligning providing an overhead information start time;
• communicating by the remote unit with the first base station;
• determining a transition time, the transition time being the time it takes the remote unit to transition from the first base station to the second base station;
• and
• handing-off the remote unit to the second base station based upon the overhead information start time and the transition time.
