In order to facilitate understanding of the embodiments of the present application, the following problems are first described.
< paging >
When the terminal is in an idle/inactive state, the network cannot know the specific cell in which the terminal is located, and only can grasp the general range in which the terminal is located. Therefore, when there is a service arrival or other reason that the terminal needs to enter the connected state, it is necessary to notify the terminal through a paging mechanism and trigger the terminal to enter the connected state through a random access channel (Random Access Channel, RACH).
The principle of the paging mechanism is that the paging message transmitted by the upper layer is borne by a physical downlink shared channel (Physical downlink shared channel, PDSCH) indicated by a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and the terminal monitors the PDCCH on specific time-frequency resources (such as PF and PO) and receives the paging message sent to the terminal. Therefore, to receive the paging message, the terminal first needs to calculate the POs and PF where paging may occur, then starts to monitor the PDCCH on the corresponding subframe, and if the paging RNTI (P-RNTI) is found, obtains the paging message from the corresponding PDSCH according to the Resource Block (RB) allocation and modulation coding format indicated by the PDCCH. The terminal determines whether the paging message is addressed to itself according to the terminal identification (e.g., UE ID) carried in the paging message. The PF and the PO are calculated by the terminal according to configuration information of the network.
< SSB Transmission characteristics >
The synchronization signal blocks (Synchronization Signal Block, SSB) can be carried on a specific beam after beamforming for transmission, and a group of synchronization signal blocks form a group of SSB burst sets and are sent in a beam scanning manner in the time domain, so that full cell coverage of the synchronization signal is realized.
All SSBs in a set of SSB bursts are constrained to be within one system field, each SSB being given a certain and unique index, i.e. SSB index, within one SSB burst set. When a terminal detects a certain SSB, the timing sequence of the SSB in the system field can be determined by identifying SSB index in the SSB. The locations available for transmitting the synchronization signal blocks within a time slot are also limited, the protocol convention: 1. the first two symbols at the starting position of the time slot are reserved for the control channel and are not used for synchronous signal block transmission; 2. the last two symbols at the end position of the time slot are reserved as uplink control channel resources for standby and are not used for synchronous signal block transmission; 3. and a certain symbol interval is reserved between two continuous synchronous signal blocks and is used for supporting flexible uplink and downlink transmission conversion of the system.
< SSB Transmission period >
The SSB burst set is periodically transmitted, and the period parameters of the SSB periodic transmission are mainly divided into two cases: in the first case, when searching a cell, the terminal does not obtain the period configuration of the SSB, and the protocol agrees that the terminal can assume that the SSB transmission period is 20ms at this time; in the second case, for a terminal that is not initially accessed, the period of SSB may be reconfigured by SIB1, and various periods of 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc. may be supported.

The SSB may be an SSB in an existing mechanism, i.e. satisfying SSB transmission characteristics in an existing mechanism, or may be an SSB for network power saving. In particular, if the SSB is a network energy-saving SSB, the SSB may be different from the SSB of the existing mechanism in location or may be different in structure, which is not limited.

At this time, the terminal may determine the paging configuration according to the received first information and/or SSB.
According to the configuration determining method, the terminal can determine the paging configuration according to the received first information and/or SSB.

step 2: at time t1, the terminal calculates the positions of PF and PO according to the following formula:
PF：(SFN+PF_offset)mod T＝CSFN
PO：i_s＝floor(CUE_ID2/N)mod N S
step 3: when the terminals such as UE1, UE2 and the like have data to arrive, the network initiates paging under the PF and PO positions;
Step 4: and all idle/inactive state UE performs paging monitoring at the PF and PO positions.

step 1: the terminal recalculates its PF and PO locations based on this SSB location in the following manner:
PF position: assuming that the SSB transmission period is 20ms, SFNs transmitting SSBs are #1, #3, #5, #7, #9, etc., PFs corresponding to UEs in all idle/active states may be on SFNs #1, #3, #5 (where the period of the PF is 1 time of the period of the SSB), or SFNs #1, #5, #9 (where the period of the PF is 2 times of the period of the SSB); that is, the SFN of the PF is selected from the SFNs of the SSB, and the period of the PF is an integer multiple of the period of the SSB
-PO position: after the PF position is determined:
-the UE calculates PO location according to the configuration: for example, calculating PDCCH monitoring time through a tagSearchspace and a controlResourceSet indicated by PDCCH-ConfigCommon in SIB1, and further determining a PO position according to the number of SSB in SSB Burst and first PDCCH-MonitoringOccasionofPO;
-when the PO location number is greater than 1, e.g. the Ns value configured in PCCH-Config is 2, then the UE listens to the first PO by default;

step 2: at a certain time, the terminal receives second indication information and effective time t2 of paging configuration (as indicated by third indication information) through SIB1 or MIB, wherein the second indication information indicates configuration parameters M1, M2 and N S Assuming m1=m2=onesixteentht, i.e. m1=m2=2, the first 2 PFs are active, N S =2, 2 POs in each PF, as shown in fig. 3B;
step 3: at time t2, the terminal calculates the positions of PF and PO according to the following formula:
PF：(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod M1)
PO：i_s＝floor(UE_ID/M2)mod N S
for example, the UE_ID may be equal to 5G-S-TMSI mod 1024 or 0 (e.g., when the terminal does not have 5G-S-TMSI mod 1024)
Step 4: when the terminals such as UE1, UE2 and the like have data to arrive, the network initiates paging under the PF and PO positions;
