Switching Between Remote Radio Heads

An apparatus comprising at least one processor;

• and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
• to select a dominant path from a plurality of paths based at least in part on measurements of the plurality of paths, where a path describes a communication route from a mobile device to an access point via a remote radio head;
• to select a plurality of non-dominant serving paths from the plurality of paths based at least in part on the measurements;
• to determine a timing window based at least in part on the dominant path;
• to determine a timing advance for the mobile device based at least in part on the timing window;
• and
• to send the timing advance to the mobile device.

A computer readable medium tangibly encoded with a computer program executable by a processor to perform actions comprising:

• selecting a dominant path from a plurality of paths based at least in part on measurements of the plurality of paths, where a path describes a communication route from a mobile device to an access point via a remote radio head;
• selecting a plurality of non-dominant serving paths from the plurality of paths based at least in part on the measurements;
• determining a timing window based at least in part on the dominant path;
• determining a timing advance for the mobile device based at least in part on the timing window;
• and
• sending the timing advance to the mobile device.

An apparatus comprising:

• means for selecting a dominant path from a plurality of paths based at least in part on measurements of the plurality of paths, where a path describes a communication route from a mobile device to an access point via a remote radio head;
• means for selecting a plurality of non-dominant serving paths from the plurality of paths based at least in part on the measurements;
• means for determining a timing window based at least in part on the dominant path;
• means for determining a timing advance for the mobile device based at least in part on the timing window;
• and
• means for sending the timing advance to the mobile device.
