Abstract

The embodiment of the invention provides a method and base station for determining non-detection of down link control information. The method comprises that: a receiving terminal sends data through a physical uplink shared channel (PUSCH), and the data is demodulated, so a demodulation result is obtained; and if the signal quality threshold value of the demodulation result is smaller than a preset lowest threshold value, the terminal is determined that the down link control information is not detected. The base station comprises a processing module and a determining module. The scheme provided by the embodiment of the invention can effectively detect the non-detection of DCI0 at UE side, so caused by non-detection are avoided, and the spectral efficiency of the base station is improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method for determining missed detection of downlink control information and a base station. Background technique [0002] Long Term Evolution (abbreviated as: LTE) is a broadband wireless technology standard proposed by the 3rd Generation Partnership Project (abbreviated as: 3GPP), which is a high data rate, low delay and A mobile communication system standard based on full packet. In LTE, downlink control information (Downlink Control Information, DCI for short) is control signaling used by a base station (NodeB) to schedule user equipment (User Equipment, UE for short), DCI0 (DCI numbered 0 ) represents the control signaling for the NodeB to schedule the UE to perform uplink data transmission. When the NodeB receives the UE's resource scheduling request or the UE has excess data that has not been sent, the NodeB instructs the UE to perform data transmi...
