Problems solved by technology

[0009] On the other hand, if the application of TDM eICIC for cross-frequency measurement requires measurement restrictions, the UE may need to configure many measurement restrictions, which will lead to high complexity for the UE
Another problem is that for cross-frequency scenarios, when RSRQ measurements have measurement gaps, the resulting measurement opportunities and TDM ICIC constraints may be too few, which will cause greater impact
Even if the RSRQ measurement meets the appropriate measurement constraints, the UE's RSRQ measurement results may still fluctuate greatly due to too few measurement samples

Embodiment Construction

[0019] The following descriptions are preferred embodiments for implementing the present invention, and some embodiments are illustrated by the accompanying drawings.

[0020] figure 1 It is a schematic diagram of a UE measurement method for interference coordination in the wireless communication system 100 according to an embodiment of the present invention. The wireless network 100 includes a macro base station MeNB101 , a micro base station PeNB102 and a user equipment UE103 . MeNB 101 provides coverage of macro cell 111 , while PeNB 102 provides coverage of micro cell 112 and its cell region extension (Cell Region Extension, CRE) 113 . exist figure 1 In the example shown, both the micro cell 112 and the micro cell CRE 113 are located within the macro cell 111, thus causing a macro-micro inter-interference interference scenario.

[0021]In general, an interference-causing device (such as an interferer) may use ABS or suppressed subframes to perform ICIC to protect an i...

Abstract

A method of UE RSRQ measurement precaution for interference coordination is provided. The UE receives radio signals of a neighbor cell under measurement. The neighbor cell applies a TDM silencing pattern for inter-cell interference coordination (TDM ICIC). The UE determines a measurement pattern that includes multiple subframes. The UE performs RSRQ measurements of the cell over multiple subframes and obtains multiple RSRQ measurement samples. The UE derives RSRQ measurement result by estimating the multiple RSRQ samples and applying a weighted average. RSRQ samples estimated to be more applicable are taken into account to more extent (e.g., applied with more weight), and/or RSRQ samples estimated to be less applicable are taken into account to less extent (e.g., applied with less weight, or discarded with zero weight). With UE precaution, a more predictable RSRQ measurement result is produced.

Description

[0001] cross reference [0002] This application claims the priority of U.S. Provisional Application No. 61 / 441,744, filed on February 11, 2011, entitled "User Equipment Reference Signal Reception Quality Measurement and Early Warning Method" based on 35 U.S.C. §119, and this application is regarded as refer to. technical field [0003] The present invention relates to wireless network communication, and in particular to enhancing Inter-cell Interface Coordination (ICIC) User Equipment (UE) Reference Signal Received Quality (RSRQ) measurement. Background technique [0004] In the eighth / ninth version of the Long Term Evolution (LTE) standard of the third generation partnership project (3rd Generation Partnership Project, 3GPP), the ICIC is introduced. The basic idea of ​​the ICIC is to implement inter-cell interference control through a radio resource management (Radio Resource Management, RRM) method. ICIC is essentially a multi-cell RRM function, which needs to consider...
