Embodiment 1

[0029] Embodiment one, see figure 1 Detailed description, figure 1 It is a schematic flow chart of the method of Embodiment 1 of the present invention,

[0030] Step 101: Determine that the information of the ICIC has changed.

[0031] In this embodiment, the change of ICIC information includes the change of the state and the change of some parameters and configuration information in the open state, including the change from the open state to the closed state, or the change from the closed state to the open state, or Some parameters and configuration information have changed in the enabled state. For example, when the cell edge throughput is low, the interference level is high, or the PRB resources available to the scheduler are abundant, the ICIC algorithm is turned on; in the opposite case, the algorithm is turned off. Regardless of the change, the terminal needs to be notified in time to instruct the terminal to report the corresponding reference signal received power ac...

Embodiment 2

[0036] Embodiment two, see figure 2 Detailed description, figure 2 It is a schematic flow chart of the method of Embodiment 2 of the present invention.

[0037] Step 201: The state of the ICIC on the network side changes from the off state to the on state.

[0038] In this embodiment, when the state of the ICIC changes, the terminal needs to be notified in time, so as to instruct the terminal to perform corresponding measurement report according to the state of the ICIC.

[0039] Step 202: Update the measurement configuration message.

[0040] In this embodiment, when the state of the ICIC on the network side changes from the off state to the on state, the updated measurement configuration message includes the newly added reference signal received power measurement event ID corresponding to the ICIC, measurement object information and report configuration.

[0041] In this embodiment, there are two ways to add measurement event ID, measurement object information, and repo...

Embodiment 3

[0056] Embodiment three, refer to image 3 Detailed description, image 3 It is a schematic flow chart of the method in Embodiment 3 of the present invention.

[0057] Step 301: The state of the ICIC on the network side changes from the off state to the on state.

[0058] In this embodiment, the state of the ICIC needs to be notified to the terminal in time, so as to instruct the terminal to perform corresponding measurement reports according to the state of the ICIC.

[0059] Step 302: Update the measurement configuration message.

[0060] In this embodiment, when the state of the ICIC on the network side changes from the off state to the on state, the updated measurement configuration message includes the newly added reference signal received power reporting threshold judgment criterion corresponding to the ICIC in the report configuration, and the report configuration is the same as that for mobile It is associated with the measurement event ID of the performance measure...

Abstract

The embodiment of the invention discloses an information sending method and a device. The method comprises the following step: sending information to a terminal when ICIC information is changed, and the information comprises parameters indicating the terminal to upgrade the ICIC information. The embodiment of the invention also provides a corresponding device. When the method and the device provided by the embodiment of the invention are used, when the ICIC information is changed, information is sent to the terminal, the terminal can obtain the ICIC information in time for thus doing corresponding measurement to be reported to the leadership, and the system performance and the accuracy of the ICIC algorithm are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending information. Background technique [0002] The Long Term Evolution (LTE) is an evolution standard developed by the 3rd Generation Partnership Project (3GPP) organization based on the Universal Mobile Telecommunications System (UMTS) network. In the LTE system, the cell edge users are close to neighboring cells, and are easily interfered by uplink and downlink interference from neighboring cell users and base stations. Therefore, adjacent cells are at the cell edge, and if they use the same frequency band, it will cause relatively large inter-cell interference. [0003] The LTE system uses Inter Cell Interference Coordination (ICIC) technology to reduce shared channel interference. This technology restricts the Physical Resource Block (PRB) used by cell edge users, so that the In adjacent areas, terminals belonging to adjacent cells do not occupy...
