Abstract

Disclosed are a method and device for testing demodulation performance of a PUSCH channel. The method includes: triggering PUSCH service data used for testing, and sending the PUSCH service data via the PUSCH channel to be tested; acquiring HARQ feedback generated after the PUSCH channel to be tested has performed HARQ processing on the PUSCH service data on the base station side; acquiring a TA adjusted value generated when the PUSCH channel to be tested performs an adjustment on the time bias of the PUSCH channel to be tested on the base station side; and adjusting the sending of the PUSCH service data according to the HARQ feedback and the TA adjusted value, and testing in a circular manner. The technical solution provided by the present invention solves the problem in the prior art that there is a lack of means for channel performance integration testing, thus achieving the effect of comprehensively and effectively evaluating PUSCH channel performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) channel demodulation performance testing method and device. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) system, there are certain requirements on the demodulation performance of the channel, and the quality of the channel demodulation performance directly affects the performance of the LTE system. Currently, there are various channel performance testing methods and devices. For example, vector signal generators and receiver testers can meet various channel models and mobile scenarios for channel performance testing. 3GPP TS 36.141 (3rd Generation Partnership Project Technical Specification Group; Radio Access Network; Evolved Universal Terrestrial RadioAccess; Base Station conformance testing, 3rd Generation Partnership Project Technical Specification Group; Wireless ...
