Problems solved by technology
[0003] Due to the discontinuous transmission of the unlicensed spectrum, it is necessary to design the discovery reference signal (DRS, Discover Reference Signal) to take on the functions of cell identification, synchronization and RRM measurement. Correspondingly, it is also necessary to determine the physical downlink control channel (PDCCH, Physical Downlink Control Channel ) at the monitoring time within the DRS transmission duration, the existing methods for determining the PDCCH monitoring time are generally based on the continuously transmitted licensed spectrum, which is not applicable to the situation of unlicensed spectrum, which will lead to inflexible and insufficient monitoring time of PDCCH precise

The invention relates to a method and a device for determining the monitoring moment of a physical downlink control channel, and the method comprises the steps: receiving a synchronization signal block SSB in an unlicensed spectrum; and determining the monitoring moment of a physical downlink control channel (PDCCH) according to the index of the SSB. The device comprises: a synchronization signalblock receiving unit for receiving a synchronization signal block SSB in an unlicensed spectrum; and a monitoring moment determining unit, used for determining the monitoring moment of a physical downlink control channel PDCCH according to the index of the SSB. By determining the monitoring moment of the PDCCH according to the index of the SSB in the unlicensed spectrum, the monitoring moment of the PDCCH in the unlicensed spectrum can be flexibly determined by adopting the method and the device for determining the monitoring moment of the physical downlink control channel in the embodiment ofthe invention.
Description
technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a method and device for determining a monitoring time of a physical downlink control channel. Background technique [0002] The 3rd Generation Partnership Project (3GPP, The 3rd Generation Partnership Project) standards organization will study how to deploy new radio communication (NR, New Radio) networks on unlicensed spectrum, so as to achieve fair and effective use of unlicensed spectrum and improve NR system for data transfer rate purposes. There are three ways for NR to use the unlicensed spectrum, one is: the NR cell of the unlicensed spectrum is the main cell; the other is: the user equipment (UE, User Equipment) accesses the cell through the long-term evolution (LTE, Long Term Evolution) The NR cell of unlicensed spectrum, the last one is the NR cell of UE accessing the unlicensed spectrum through the NR cell, the latter two methods of licensed spectrum...
