Embodiment Construction

[0041]Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. The detailed description disclosed below with reference to the accompanying drawings is not intended to indicate the only embodiments of the invention but rather explains exemplary embodiments of the invention. In the following detailed description of the invention, details are included to facilitate a comprehensive understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without these details. For example, although the following descriptions are made in detail on the assumption that the wireless mobile communication system includes the 3GPP LTE system, they are applicable to other mobile communication systems than the features inherent to the 3GPP LTE.

Abstract

The invention relates to a dual mode mobile terminal in a MIMO wireless communication system and a control method thereof and discloses a dual mode terminal and a control method thereof. The terminal comprises a first antenna, a second antenna, a first communication module and a second communication. If the first communication module receives a command for measuring the signal quality of a second base from a LTE base, RI (rank indicator) as 1 is reported to the LTE base. Based on a layer 1 choice and report PMI, the first communication module only uses the first antenna to receive a BLER signal equal to or more than 0.1 from the LTE base. Therefore, the dual module terminal of the invention can efficiently measure the CDMA signal quality by keeping receiving the LTE signal without clearance measurement and can receive the BLER under the condition of a level similar to the normal situation in the process of measuring the CDMA signal quality.

Description

[0001] Cross References to Related Applications [0002] Pursuant to Section 35 of U.S.C. 119(a), this application claims the benefit and priority of the earlier filing date of U.S. Provisional Application 61 / 157,908, filed March 6, 2009, the contents of which are hereby incorporated by reference in their entirety . technical field [0003] The present invention relates to a mobile terminal, in particular to a dual-mode mobile terminal and a control method thereof. Although the invention is suitable for a wide range of applicability, it is particularly suitable for receiving LTE signals in the course of measuring the quality of CDMA signals. Background technique [0004] Generally, a dual-mode mobile terminal is a mobile terminal capable of supporting two different wireless communications in a communication system. Dual-mode mobile terminals are mainly used in areas where different kinds of communication networks exist simultaneously. As a representative example of a dual...
