Abstract
A method and apparatus for transmitting a neighbor cell measurement command in a wireless communication system are disclosed. The method for transmitting a measurement command of a neighbor cell by a serving cell in a wireless communication system includes: confirming user equipment (UE) capability information related to cell range extension (CRE); and transmitting a measurement command including a list of cells to be measured to the UE, wherein, if the UE has CRE-related capability, the measurement command includes neighbor-cell reference signal (RS) information.
Claims12
A method for transmitting, by a serving cell, a measurement command of a neighbor cell in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE) by the serving cell, measurement information including information indicating the neighbor cell and a subframe pattern for measuring the neighbor cell;
- and
- transmitting, to the UE by the serving cell, cell specific reference signal (CRS) assistance information related to an aggressor cell of the neighbor cell,
- wherein the CRS assistance information includes information indicating the aggressor cell, a number of antenna ports of the aggressor cell for transmitting a CRS and a multimedia broadcast multicast service single frequency network (MBSFN) configuration of the aggressor cell, and
- wherein the CRS assistance information is used for mitigating CRS interference of the aggressor cell on one or more subframes indicated by the subframe pattern.
A serving cell apparatus for transmitting a measurement command of a neighbor cell in a wireless communication system, the apparatus comprising:
- a transmission (Tx) module;
- and
- a processor configured to control the Tx module to:
- transmit measurement information including information indicating the neighbor cell and a subframe pattern for measuring the neighbor cell to a user equipment (UE), and
- transmit cell specific reference signal (CRS) assistance information related to an aggressor cell of the neighbor cell to the UE,
- wherein the CRS assistance information includes information indicating the aggressor cell, a number of antenna ports of the aggressor cell for transmitting a CRS and a multimedia broadcast multicast service single frequency network (MBSFN) configuration of the aggressor cell, and
- wherein the CRS assistance information is used for mitigating CRS interference of the aggressor cell on one or more subframes indicated by the subframe pattern.
A method for measuring a neighbor cell by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, by the UE, measurement information including information indicating the neighbor cell and a subframe pattern for measuring the neighbor cell;
- receiving, by the UE, cell specific reference signal (CRS) assistance information related to an aggressor cell of the neighbor cell,
- wherein the CRS assistance information includes information indicating the aggressor cell, a number of antenna ports of the aggressor cell for transmitting a CRS and a multimedia broadcast multicast service single frequency network (MBSFN) configuration of the aggressor cell;
- and
- performing, by the UE, a measurement by of the neighbor cell by mitigating CRS interference of the aggressor cell on one or more subframes indicated by the subframe pattern.
A user equipment (UE) apparatus for use in a wireless communication system comprising:
- a reception (Rx) module;
- a transmission (Tx) module;
- and
- a processor configured to:
- control the Rx module to receive measurement information including information indicating the neighbor cell and a subframe pattern for measuring the neighbor cell,
- control the Rx module to receive cell specific reference signal (CRS) assistance information related to an aggressor cell of the neighbor cell,
- wherein the CRS assistance information includes information indicating the aggressor cell, a number of antenna ports of the aggressor cell for transmitting a CRS and a multimedia broadcast multicast service single frequency network (MBSFN) configuration of the aggressor cell, and
- control the Rx module and the Tx module to perform a measurement of the neighbor cell by mitigating CRS interference of the aggressor cell on the one or more subframes indicated by the subframe pattern.
