Problems solved by technology

However, in actual communication applications, it may happen that the UE is not scheduled and fails to detect the PDCCH belonging to the UE, which makes it difficult to measure the BLER of the PDCCH (including the BLER of the PCFICH), so it is easy to misjudgment in practical applications; In addition, in the existing LTE communication system, as the received signal quality of the pilot signal changes, the transmitter tries its best to

Abstract

The embodiment of the invention discloses a wireless link quality monitoring method and device and a wireless transmitting-receiving unit. The method comprises the steps of receiving a wireless frame signal through a downlink wireless link, obtaining the period according to the presetting, and obtaining the signal to noise ratio of a pilot signal in the wireless frame signal and/or the block error rate of a service channel; according to the obtained signal to noise ratio and/or the block error rate of the service channel, combining the block error rate of a physical downlink control channel, and judging whether the downlink wireless link is synchronous or is out of synchronization. According to the embodiment of the method, the accuracy and reliability of wireless link quality monitoring can be improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a wireless link quality monitoring method and device, and a wireless transmitting and receiving unit. Background technique [0002] The Long Term Evolution (Long Term Evolution, hereinafter referred to as: LTE) communication system is the evolution of the third generation mobile communication system (The 3rd Generation Telecommunication, hereinafter referred to as: 3G). Different from the circuit switching mode adopted by the previous cellular system, the LTE communication system only supports packet switching services, which can provide higher service transmission rates. The uplink and downlink peak data rates provided within the 20MHz bandwidth are 100Mbit / s and 50Mbit / s, to provide users with richer services. [0003] The LTE communication system may simultaneously use Frequency Division Duplex (Frequency Division Duplex, hereinafter referred to as: FDD) and Time Division ...
