Abstract

A measurement method, a sending method, a measurement apparatus, and a sending system for interference coordination are disclosed. The measurement method includes: obtaining measurement configuration information, and obtaining measurement resource information for restrictive measurement; performing measurement according to the measurement configuration information and the measurement resource information for restrictive measurement, and obtaining a measurement result; and reporting the measurement result. Therefore, the interfered UE can perform measurement accurately and report the measurement result as a basis of handover.

Claims

1. A method for measurement of interference coordination, comprising:

receiving, by a user equipment in an aggressor cell from a base station of the aggressor cell, measurement configuration information and measurement resource information for restrictive measurement, wherein the measurement resource information for restrictive measurement indicates a radio resource management (RRM) measurement of a neighboring victim cell to be performed during a time subset of restricted time resources used for Inter-Cell Interference Coordination (ICIC);

performing, by the user equipment, corresponding unrestrictive measurement according to the measurement configuration information, and obtaining an interference value representative of an interference level;

performing, by the user equipment, the RRM measurement of the neighboring victim cell during the time subset if the interference value is greater than an interference threshold; and

transmitting, by the user equipment, an RRM measurement result to the base station of the aggressor cell, wherein the RRM measurement result is obtained from the RRM measurement.

2. The method according to claim 1, wherein the measurement resource information for restrictive measurement comprises subframe configuration information applied to enhanced Inter-Cell Interference Coordination (eICIC) used in Time Division Multiplex (TDM).

3. The method according to claim 1, wherein receiving the measurement configuration information comprises:

obtaining configuration information of unrestrictive measurement and a measurement type indication; and

wherein the measurement type indication indicates to perform the RRM measurement by using a measurement indication of using specific resource corresponding to measurement resource information for restrictive measurement, and indicates to perform the RRM measurement by using a measurement indication of performing unrestrictive measurement.

4. The method according to claim 1, wherein receiving the measurement configuration information comprises:

obtaining configuration information for unrestrictive measurement and indication of starting and stopping measurement; and

wherein the indication of starting and stopping measurement indicates to start and stop restrictive measurement, or indicates to start and stop unrestrictive measurement.

5. An apparatus in an aggressor cell for interference coordination, comprising:

a receiver, configured to receive measurement configuration information and measurement resource information for restrictive measurement from a base station of the aggressor cell, wherein the measurement resource information for restrictive measurement indicates a radio resource management (RRM) measurement of a neighboring victim cell to be performed during a time subset of restricted time resources used for Inter-Cell Interference Coordination (ICIC);

7. The apparatus according to claim 5, wherein the receive measurement configuration information comprises:

obtain configuration information of unrestrictive measurement and a measurement type indication; and

wherein the measurement type indication indicates to perform the RRM measurement by using a measurement indication of using specific resource corresponding to measurement resource information for restrictive measurement, and indicates to perform the RRM measurement by using a measurement indication of performing unrestrictive measurement.

8. The apparatus according to claim 5, wherein the receive measurement configuration information comprises:

obtain configuration information for unrestrictive measurement and indication of starting and stopping measurement; and

wherein the indication of starting and stopping measurement indicates to start and stop restrictive measurement, or indicates to start and stop unrestrictive measurement.
