Abstract
A method for performing reference signal measurements on a plurality of cells may include obtaining a plurality of channel quality metrics for the plurality of cells, assigning a plurality of cell measurement priority rankings to the plurality of cells based on the plurality of channel quality metrics, based on the plurality of cell measurement priority rankings, selecting one or more target cells from the plurality of cells to measure during one or more reference signal periods to obtain a plurality of reference signal measurements, and reporting the plurality of reference signal measurements to a communication network.
Claims22
A mobile communication device comprising an RF transceiver and a baseband processing circuit adapted to interact with the RF transceiver to transmit and receive radio signals on a communication network, the baseband processing circuit configured to:
- obtain a plurality of channel quality metrics for a plurality of cells;
- identify one or more cells of the plurality of cells as detectable based on the plurality of channel quality metrics;
- identify one or more cells of the plurality of cells as undetectable based on the plurality of channel quality metrics;
- assign a plurality of cell measurement priority rankings to the plurality of cells based on the plurality of channel quality metrics;
- wherein one or more of the detectable cells having one or more higher respective channel quality metrics is assigned a lower cell measurement priority ranking than a detectable cell having a lower respective channel quality metric;
- based on the plurality of cell measurement priority rankings, select one or more target cells of the plurality of cells to measure during one or more reference signal periods to obtain a plurality of reference signal measurements;
- and
- report the plurality of reference signal measurements to a communication network.
A mobile communication device comprising:
- an RF transceiver and a baseband processing circuit adapted to interact with the RF transceiver to transmit and receive radio signals on a communication network, the baseband processing circuit configured to:
- identify a plurality of reference signal time periods allocated for cell measurement;
- identify one or more cells of the plurality of cells as undetectable based on the plurality of channel quality metrics;
- obtain a plurality of channel quality metrics for a plurality of cells;
- for each of the plurality of reference signal time periods, select one or more target cells from the plurality of cells to measure and exclude one or more remaining cells of the plurality of cells from measurement based on the plurality of channel quality metrics;
- wherein the one or more remaining cells have the highest respective channel quality metrics but is assigned a lower cell measurement priority ranking than a detectable cell having a lower respective channel quality metric;
- and
- report a plurality of reference signal measurements obtained during the plurality of reference signal time periods to a communication network.
