Abstract
A mobile station in a wireless communication network is disclosed. The mobile station includes a transceiver coupled to a processor configured to perform measurements of signals of one or more cells of a wireless communication system during a first set of subframes, to cause the transceiver to transmit a measurement report including at least the measurements of signals of the one or more cells, and to indicate that the measurements of the one or more cells were performed during the first set of subframes.
Claims8
A mobile station configured to be connected to a serving base station comprising:
- a processor;
- a transceiver coupled to the processor,
- the processor configured to determine a first almost blank (AB) subframe pattern including a first set of AB subframes during which a neighboring base station is only allowed to transmit a restricted set of information;
- the processor configured to determine a second AB subframe pattern including a second set of AB subframes during which a second neighboring base station is only allowed to transmit a second restricted set of information;
- the processor configured to switch from performing measurements of signals of the serving base station using the first AB subframe pattern including the first set of AB subframes to performing measurements of signals of the serving base station using the second AB subframe pattern including the second set of AB subframes, if a signal level of the second neighboring base station is higher than a signal level of the neighboring base station;
- the processor configured to cause the transceiver to transmit a measurement report including at least the measurements of signals of the serving base station;
- and
- the processor configured to indicate that the measurements of signals of the serving base station were performed using at least one of the first AB subframe pattern including the first set of AB subframes and the second AB subframe pattern including the second set of AB subframes.
A method in a mobile station connected to a serving base station, the method comprising:
- determining a first almost blank (AB) subframe pattern including a first set of AB subframes during which a neighboring base station is only allowed to transmit a restricted set of information;
- determining a second AB subframe pattern including a second set of AB subframes during which a second neighboring base station is only allowed to transmit a second restricted set of information;
- switching from performing measurements of signals of the serving base station using the first AB subframe pattern including the first set of AB subframes to performing measurements of signals of the serving base station using the second AB subframe pattern including the second set of AB subframes, if a signal level of the second neighboring base station is higher than a signal level of the neighboring base station;
- transmitting a measurement report including at least the measurements of signals of the serving base station;
- and
- indicating that the measurements of the signals of the serving base station were performed using at least one of the first AB subframe pattern including the first set of AB subframes and the second AB subframe pattern including the second set of AB subframes.
