Abstract
A system and method for user equipment (UE) measurement timing in a relay cell are provided. A method for controller operations includes broadcasting a first pattern of time intervals to communications devices served by a controller, and for a communication device served by the controller, determining a second pattern for the communications device, where the second pattern is based on the first pattern, and transmitting the second pattern to the communications device.
Claims20
A method for controller operations, the method comprising:
- broadcasting a first plurality of subframes to a plurality of communications devices served by a controller in accordance with a first pattern of measurement gaps, the first pattern of measurement gaps specifying a first plurality of time intervals during which none of the first plurality of subframes are transmitted;
- determining a second pattern of measurement gaps specifying a second plurality of time intervals during which none of a second plurality of subframes are to be transmitted, wherein the second pattern of measurement gaps is determined in accordance with the first pattern of measurement gaps such that at least some of the second plurality of time intervals overlap with some of the first plurality time intervals;
- and
- communicating the second pattern of measurement gaps to a first one of the plurality of communications devices.
