Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] see figure 1 , an embodiment of the present invention provides a method for identifying SAIC capabilities, including:

[0024] 101: Use alpha-QPSK (Quadrature Phase Shift Keying, Alpha Quadrature Phase Shift Keying) modulation and GMSK (Gaussian Minimum Shift Keying, Gaussian Minimum Shift Keying) modulation to eliminate non-single antenna interference and Non-SAIC types of waiting test terminal.

[0025] 102: According to the corresponding downlink quality of the terminal under test under alpha-QPSK modulation and GMSK modulation, identify whether the terminal under test has a single-antenna interference cancellation SAIC capability.

[0026] In the embodiment of the present invention, by using alpha-QPSK modulation and GMSK ...

Abstract

The invention discloses single antenna interference cancellation (SAIC) capability recognizing method and device which belong to the field of wireless communication. The method comprises the following steps of: respectively testing Non-SAIC type terminals to be tested by using alpha-QPSK (Quadrature Phase Shift Keying) modulation and GMSK (Guassian Minimum Shift Keying) modulation; recognizing whether the terminals to be tested have SAIC capability or not according to the corresponding downlink quality of the terminals to be tested under the alpha-QPSK modulation and GMSK modulation; reporting the corresponding downlink quality information to an SAIC capability recognizing device under the alpha-QPSK modulation and the GMSK modulation by the terminals to be tested so that the SAIC capability recognizing device is used for obtaining the corresponding downlink quality under the alpha-QPSK modulation and the GMSK modulation according to the downlink quality information and recognizing whether the terminals to be tested have the SAIC capability or not. The device comprises a test module and a recognizing module. By the scheme, the invention can recognize a silence SAIC terminal with the SAIC capability and improve the accuracy of SAIC capability recognition.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a single-antenna interference elimination capability identification method and device. Background technique [0002] Currently, there are two types of terminals, one is a SAIC (Single Antenna Interference Cancellation, single-antenna interference cancellation) terminal, and the other is a Non-SAIC (non-single-antenna interference cancellation) terminal. [0003] In the current communication system, the network side equipment determines whether the terminal has SAIC capability according to the terminal type reported by the terminal. When the reported terminal type is SAIC, the network side recognizes the terminal as having SAIC capability. When the reported terminal type is Non - In the case of SAIC, the network side identifies the terminal as not having the SAIC capability. [0004] However, a large part of non-SAIC type terminals have SAIC capability, that is, single-anten...
