Embodiment 1

[0157] The embodiment of the present invention provides a method for small cells to regularly report measurement results. It is assumed that within the coverage of the macro cell, there is a cluster1, and there is a CCU and N small cells in the cluster1. Taking small cell 1 as an example, The process flow of the method includes the following steps:

[0158] Step 1, small cell 1 measures the reception quality (RSRP / RSRQ) of all UE uplink signals in the cell;

[0159] Step 2, small cell 1 compares the measured signal quality of all UEs with a given threshold, and UEs smaller than the threshold are UEs1 to be tested in this small cell1, assuming that UEs1={UEid1, UEid2};

[0160] Step 3, the small cell 1 sends the UEs1 under test information for determining the reference signal (sounding and / or DMRS) sequence and the corresponding time-frequency resource information to the CCU;

[0161] Step 4, small cell 1 receives information from UEs to be tested in all other small cells unde...

Embodiment 2

[0168] The difference between this embodiment and Embodiment 1 lies in steps 6 and 7:

[0169] Step 6: small cell 1 receives the absolute time signaling T1 from the CCU;

[0170] Step 7: Small cell 1 obtains the reporting time T of the measurement report according to the absolute time signaling T1: T=T1;

[0171] In this embodiment, small cells and CCUs under the same cluster are synchronized.

Embodiment 3

[0173] The difference between this embodiment and Embodiment 1 lies in steps 6 and 7:

[0174] Step 6, small cell 1 receives a configuration time period P1 and a subframe offset parameter Suboffset from the CCU;

[0175] Step 7, small cell 1 determines the reporting time of the measurement report, including the system radio frame number SFN and subframe number subframe, SFN and subframe need to meet the following conditions:

[0176] SFN mod T = FLOOR(Suboffset / 10);

[0177] subframe = suboffset mod 10;

[0178] Among them: T=P1 / 10;

Abstract

The invention discloses a measurement report reporting method. The method comprises the step that a first communication node receives first signaling from a second communication node, and obtains the reporting time of a measurement report according to the first signaling, and sends the measurement report to the second communication node at the reporting time. The invention also discloses a measurement report reporting system and a communication node. With the measurement report reporting method, communication node and measurement report reporting system of the invention adopted, problems of vacant resource consumption, inaccurate measurement results and long judgment delay when measurement results are reported in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a measurement report reporting method, communication node and system. Background technique [0002] The Long Term Evolution (LTE for short) project is the evolution of the third generation of mobile communication technology (Third Generation, referred to as 3G), but it is not the fourth generation of mobile communication technology (Fourth Generation, referred to as 4G) that is commonly misunderstood by people. ), but a transition between 3G and 4G technology, it improves and enhances the air access technology of 3G, it adopts Orthogonal Frequency Division Multiplexing (OFDM) technology and multiple input multiple output (Multiple Inputs and Multiple Outputs, MIMO for short) technology, that is, multi-antenna technology is the only standard for wireless network evolution. Long Term Evolution-Advanced (LTE-Advanced, LTE-A for short) is a subsequent evolutio...
