Abstract
A method of providing information for cell measurement is provided. In the method, a first cell obtains a first pattern information indicating a subframe for performing measurement with respect a second cell. The first cell configures a subframe for performing measurement, which is different from that for performing measurement with respect the second cell. The first cell transmits a second pattern information on the subframe configured by the first cell to a user equipment (UE).
Claims24
A method of providing information for cell measurement, the method comprising:
- configuring a subframe for performing a first measurement with respect to a first cell, wherein a first position performing the first measurement is different from a second position performing a second measurement with respect to a second cell;
- and
- transmitting, from the first cell to a user equipment (UE), first pattern information indicating the first position and second pattern information indicating the second position,
- wherein the first and second pattern information indicate the first position and the second position as a bit ‘1’, respectively,
- wherein the first and second pattern information indicate at least one subframe per a radio frame, used for performing the measurements, and
- wherein a first subframe corresponding to the first pattern information is included in non-ABS (Almost Blank Subframe) subframes of the first cell, and a second subframe corresponding to the second pattern information is included in ABS subframes of the first cell.

A method of performing measurements in a UE placed within a coverage of a serving cell and a coverage of a neighboring cell, the method comprising:
- transceiving signals;
- and
- performing measurements on the serving cell and the neighboring cell on different positions in a subframe according to first pattern information and second pattern information, respectively,
- wherein the first pattern information and the second pattern information indicate the different positions for the measurements as a bit ‘1’, respectively,
- wherein the first pattern information and the second pattern information indicate at least one subframe per a radio frame, used for performing the measurements, and
- wherein a first subframe corresponding to the first pattern information is included in non-ABS (Almost Blank Subframe) subframes of the first cell, and a second subframe corresponding to the second pattern information is included in ABS subframes of the first cell.
3 more elements
A base station comprising:
- a transceiver to transceive signals;
- and
- a controller configured to:
- configure a subframe for performing a first measurement with respect to the base station, wherein a first position performing the first measurement is different from a second position performing a second measurement with respect to a neighboring cell;
- and
- transmit first pattern information indicating the first position and second pattern information indicating the second position,
- wherein the first and second pattern information indicate the first position and the second position as a bit ‘1’, respectively,
- wherein the first and second pattern information indicate at least one subframe per a radio frame, used for performing the measurements, and
- wherein a first subframe corresponding to the first pattern information is included in non-ABS (Almost Blank Subframe) subframes of the first cell, and a second subframe corresponding to the second pattern information is included in ABS subframes of the first cell.
6 more elements
A terminal comprising:
- a transceiver to transceive signals;
- and
- a controller configured to:
- perform a first measurement with respect to a serving cell and a second measurement with respect to a neighboring cell on different positions in a subframe according to first pattern information and second pattern information, respectively, when the terminal is located within a coverage of the serving cell and a coverage of the neighboring cell,
- wherein the first pattern information and the second pattern information indicate the different positions for the measurements as a bit ‘1’, respectively,
- wherein the first pattern information and the second pattern information indicate at least one subframe per radio frame, used for performing the measurements, and
- wherein a first subframe corresponding to the first pattern information is included in non-ABS (Almost Blank Subframe) subframes of the first cell, and a second subframe corresponding to the second pattern information is included in ABS subframes of the first cell.
