Problems solved by technology

[0007] On the other hand, when testing wireless communication systems such as LTE, the conventional implementation method is to build another test platform during debugging and measurement, which requires different platforms for testing different data flow directions, increasing The workload and complexity of testing
Moreover, in order to realize continuous testing and debugging of a large amount of data, the size of the external memory must be increased, which increases the difficulty of implementation

Abstract

The embodiment of the invention provides an adapter for user equipment and adapting method. One of the adapter comprises a radio-frequency circuit, a base band circuit and a storage. The adapter is configured between the radio-frequency circuit and the base band circuit. The adapter comprises a control unit and an execution unit. The control unit answers to one and many external signals for generating coresponding control signal. An execuation unti is configured to answering different control signals from control units, and data can be transmitted between two or three of the base band circuit, the storager and the radio-frequence, thereby realizing data of different data flow directions can be tested on the same platform, thereby substantially minimizing test work load and reducing complexity.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / 638,022, filed April 25, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the invention relate generally to wireless communications. More specifically, embodiments of the present invention relate to adapters in user equipment and adaptation methods thereof. Background technique [0004] LTE is a next-generation wireless communication system. According to the LTE protocol, the bandwidth of the LTE system varies from 1.4Mhz to 20Mhz, which corresponds to the varied input sampling rate as shown in Table 1. Therefore, receivers are required to process data at different sampling rates. [0005] Table 1: LTE bandwidth and sampling rate [0006] LTE bandwidth (Hz) Sampling rate (samples / second) 1.4M 1.92M 3M 3.84M 5M 7.68M 10M 15.36M ...
