Fig. 1 shows a frame structure diagram of a 3GPP NR system, and as can be seen from fig. 1, in a radio frame with a time domain length of 10ms, each radio frame is divided into 10 subframes with the same size and length of 1ms, and each subframe may include a plurality of slots at different subcarrier intervals. Each slot is formed of a certain number of symbols, and the number of symbols is determined by a Cyclic Prefix (CP) type.
The NR system supports multi-beam synchronization signal, secondary synchronization signal, and physical broadcast channel transmission. Fig. 2 shows a schematic diagram of the structure of a synchronization signal block (SSB, SS/PBCH block), and as can be seen from fig. 2, the SSB is formed of 4OFDM symbols and is located at a position of 5ms in relation to the subcarrier spacing (SCS) and the number of beams L.
Fig. 3 shows a schematic diagram of the receiving positions of SSBs under different SCS, and as can be seen from fig. 3, there are 5 cases of the receiving positions (or receiving time) of SSBs in each time slot under different SCS, specifically:
case A-15kHz subcarrier spacing: the first time domain symbol of the candidate SS/PBCH block is located at {2,8} +14 × n, where n is 0,1 when the carrier frequency is equal to or less than 3 GHz; when the carrier frequency is less than or equal to 6GHz, n is 0,1,2 and 3.
Case B-30kHz subcarrier spacing: the first time domain symbol of the candidate SS/PBCH block is located at {4,8,16,20} +28 × n, where n is 0 when the carrier frequency is equal to or less than 3 GHz; when the carrier frequency is less than or equal to 6GHz, n is 0, 1.

In the NR system, there are three multiplexing modes of the SSB and the Control-Resource Set (core Set), one of which is a Time Division Multiplexing (TDM) mode, that is, the SSB receiving time is different from the PDCCH monitoring time, and the UE monitors the search space in two consecutive time slots. Therefore, the specific way for the UE to determine the monitoring time of the PDCCH is as follows: for SSB index i, if

for the length of the search space, μ e{0,1,2,3} is SCS based on PDCCH, both O and M are related parameters, tables 1 and 2 are lists of specific monitoring time instants of PDCCH, and the specific monitoring time instants under different related parameters are shown in tables 1 and 2:

The monitoring time of the PDCCH shown in tables 1 and 2 is actually monitored on the basis of a continuous authorized spectrum, and the 3GPP standard organization will study how to deploy the NR network on the unlicensed spectrum, so as to achieve the purpose of fairly and effectively utilizing the unlicensed spectrum and improving the data transmission rate of the NR system. NR has three ways to use unlicensed spectrum, one is: an NR cell of the unlicensed spectrum is used as a main cell; the other is as follows: the UE accesses the NR cell of the unlicensed spectrum through the LTE cell, the last is the NR cell of the unlicensed spectrum through the NR cell, and the licensed spectrum and the unlicensed spectrum in the last two modes can be used in combination in a mode similar to carrier aggregation, that is, one terminal and the gNB may simultaneously operate on the licensed spectrum and the unlicensed spectrum.
Due to the discontinuous transmission of the unlicensed spectrum, if the existing calculation mode of the PDCCH monitoring time is continuously applied to the scene of the unlicensed spectrum, the time for monitoring the PDCCH is not accurate enough and is not flexible enough.
In order to solve the above problem, this embodiment discloses an application example of a method for determining a monitoring time of a physical downlink control channel, in this example, in a state of an unlicensed spectrum, after receiving an SSB, according to an index of the SSB, a time corresponding to a first downlink symbol after an SSB index end symbol is used as a time for monitoring a PDCCH.
