Embodiment 1

[0214] Figure 9 According to the preferred embodiment of the present invention, the base station notifies the UE of the CSI-RS resource configuration and DRS resource configuration combination information and corresponding ID information of all its TPs through RRC signaling; notifies the UE of the TP corresponding to a certain ID through L1 signaling (CSI -RS resource) is on / off flowchart. like Figure 9 As shown, the process may include the following steps:

[0215] Step S902: the base station notifies the UE of the CSI-RS resource configuration information and the DRS resource configuration information of all TPs in the form of a set, and uses an ID to identify the set. The RRC signaling may include but not limited to the following:

[0216]

[0217] Step S904: When a certain TP is closed, the base station explicitly informs the UE of the closed ID, and the notification can be carried by physical layer signaling (DCI) or RRC signaling.

[0218] Step S906: the disable...

[0223] Figure 10 According to the preferred embodiment of the present invention, the base station notifies the UE of the CSI-RS resource configuration and DRS resource configuration combination information and corresponding ID information of all TPs through RRC signaling; and the TP (CSI-RS resource) corresponding to the ID is turned on / Close the flowchart. like Figure 10 As shown, the process may include the following steps:

[0224] Step S1002: The base station notifies the UE of the CSI-RS resource configuration information and the DRS resource configuration information of all TPs in a set form, and uses an ID to identify the set; at the same time, it indicates whether a certain ID is in the ON or OFF state. The RRC signaling may include but not limited to the following:

[0225]

[0226]

[0227] Step S1004: The disabled TP stops sending CSI-RS, and starts sending only DRS.

[0228] After receiving the ON / OFF information, the UE side performs CSI-RS resource-b...

Embodiment 3

[0232] Figure 11 According to a preferred embodiment of the present invention, the base station notifies the UE of the CSI-RS resource configuration and / or DRS resource configuration and corresponding ID information sent by the TP in the ON state through RRC signaling; and the DRS resource configuration sent by the TP in the OFF state and the flow chart of the corresponding ID information. like Figure 11 As shown, the process may include the following processing steps:

[0233] Step S1102: The base station notifies the UE of the CSI-RS resource configuration information and / or DRS resource configuration information (depending on whether the TP in the ON state sends DRS) of all TPs in the ON state, and uses IDs to identify them; the base station sends all The DRS resource configuration information under the TP in the OFF state is notified to the UE, and is identified by an ID. The RRC signaling may include but not limited to the following:

Abstract

The invention discloses an information sending method, an information processing method and an apparatus. The information sending method comprises the following steps of sending multiple sets of first resource configuration information and first identification information respectively configured for each set of first resource configuration information; and sending multiple sets of second resource configuration information and second identification information respectively configured for each set of second resource configuration information. The second identification information is used for indicating that a UE adopts second resource configuration information corresponding to the second identification information for second measurement. Therefore, a base station sends DRS resource configuration information down to user equipment and the user equipment performs DRS-based RRM measurement according to the DRS resource configuration information.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending and processing information. Background technique [0002] The small cell (SmallCell) technology uses low-power wireless access nodes, which can be used to expand the coverage of the macro cell (MacroCell), offload the growing data traffic of the macro cell, and improve the efficiency of wireless spectrum resource usage. The Advanced Long Term Evolution (LTE-Advanced) system uses the SmallCell technology to increase network capacity. [0003] The SmallCell deployment scenario of the Long Term Evolution (LTE) network can be composed of two layers: a macro cell and a small cell. The LTE system is an interference-limited system, and complex interference relationships exist between macro cells and small cells and between small cells. Each cell serves the terminals in the cell through dynamic scheduling. In addition, as the user equipment (UE) moves...
