- pre-synchronization the steps that the terminal uses the SSB to perform time/frequency synchronization and AGC adjustment may be collectively referred to as pre-synchronization.
- each SSB in one SSB period usually corresponds to different beam transmission directions.
- the SSBs used by the terminal for pre-synchronization should correspond to the same beam transmission direction. Therefore, one or more SSBs used by the terminal for pre-synchronization are usually located in different SSB periods.
- the period for sending SSBs, the time interval between adjacent SSBs, and the resource locations of SSBs may be pre-specified in a protocol or configured to the terminal by a network-side device through a system message.

- UE2 does not need to use SSB1 for pre-synchronization, but when the paging indication is only sent near SSB1, UE2 also needs to receive SSB1 in order to receive the paging indication, and after being instructed to have paging, it still needs to maintain a certain working state until PO1. This can be compared to the circled part in row 3 in Figure 1f and row 7 in Figure 1f.
- the paging indication is only sent near SSB2 since UE1 cannot know whether there is a paging in advance, in order to ensure that the paging can be correctly received in the case of paging, it needs to receive SSB1 and maintain the working state until it receives the paging after SSB2. instruct. If no paging is instructed, it can be seen from the comparison of the circled part in the sixth row in Fig. 1f and the second row in Fig. 1f that more energy is wasted.

- the value of R can be configured to the terminal by the access network device, or can be pre-specified by the protocol, and is not limited.
- the terminal can know which R POs the paging indication corresponds to, and which R POs corresponding to the paging indication include the PO of the terminal, and then according to the paging indication corresponding R POs.
- PO and the sorting rule of the indication information in the first field determine which indication information corresponds to your PO, and then determine whether there is paging in your PO according to the indication information corresponding to your PO, and if there is no paging In case of emergency, stop work as soon as possible to save energy consumption.
- the terminal can determine that the paging indication corresponding to PO2 located in SSB1 also indicates PO1 and PO3, and then according to the time domain position relationship of PO3, PO2 and PO1 and the sorting rule corresponding to the indication information, determine the indication corresponding to PO2
- the information is the second indication information in the first field.
- the M bits included in the indication information corresponding to the paging occasions may be fixed or dynamically adjusted.
- the M bits included in the indication information corresponding to the paging occasions may be fixed or dynamically adjusted.
- all bits in the fixed-length paging indication are occupied as much as possible, that is, all bits are filled with available information.
- Example 1 If there are other fields indicating valid information except the first field in the paging indication, then If the field indicating valid information in the paging indication is only the first field, the value of M is
- A is the length of the paging indication
- B is the length of the fields in the paging indication indicating valid information except the first field, such as the above-mentioned second field, third field, fourth field and fifth field. total length.
- the number of bits of padding in the paging instruction can be made as small as possible, the number of bits of valid information can be made as large as possible, and the number M of further groupings at paging occasions can be made as large as possible, thereby reducing the paging falsehood of the terminal.
- the alarm probability increases the probability that the terminal is successfully paged.
- the indication information corresponding to each paging occasion includes: bits; the indication information corresponding to each paging occasion in the remaining paging occasions among the R paging occasions includes: bits.
- A is the length of the paging indication
- B is the length of the fields in the paging indication indicating valid information except the first field, such as the above-mentioned second field, third field, fourth field and fifth field. total length. It should be noted that, if the field indicating valid information in the paging indication is only the first field, the value of B in the formula shown in Example 2 is 0.
- the indication information corresponding to each paging occasion may be some indication information at the front, some indication information at the back, or some indication information on the preset position in the first field, which is not limited. For example, taking 10 bits to indicate 4 POs as an example, according to the method shown in Example 2, it can be obtained that the number of bits included in the 4 indication information corresponding to the 4 POs is ⁇ 3, 3, 2, 2 ⁇ , or ⁇ 2 , 2, 3, 3 ⁇ .
- Example 2 Through the method shown in Example 2, the existence of padding bits can be completely avoided, the number of bits of valid information is as large as possible, and the number M of further paging occasions is as large as possible, thereby reducing the paging false alarm probability of the terminal and improving the success rate of the terminal.
- the probability of paging is the probability of paging.
- the terminal device can assume that there is a quasi-co-location relationship between the paging indication and the synchronization signal block SSB closest to the paging indication.
- the QCL relationship between the paging indication and the SSB can be equivalently described as a QCL relationship between the CORESET associated with the search space where the paging indication is located and the associated (or closest) SSB.
- the QCL relationship actually represents what beam receiving parameters the terminal uses to receive signals.
- the terminal can use the same receiving beam to receive the two signals. For example, if there is a QCL relationship between the paging indication and the synchronization signal block SSB closest to the paging indication, the terminal can receive the paging indication using the same receive beam as the SSB. If there is a QCL relationship between the paging indication and the SSB associated with the paging indication, the terminal may receive the paging indication using the same receive beam as the SSB associated with the paging indication.
- the indication information corresponding to the paging occasion received by the terminal may be inconsistent, so that the terminal cannot achieve the purpose of energy saving through the paging indication.
- a terminal with poor coverage needs to receive SSB1 and SSB2 for pre-synchronization. If the contents indicated by the paging indications near SSB1 and SSB2 are consistent, the terminal receives the paging indication near SSB1 and obtains an indication that it will not be paged. , you can enter the sleep state to save energy. If the contents indicated by the paging indications near SSB1 and SSB2 are inconsistent, the terminal has to receive the paging indications near SSB2 for insurance purposes, and thus the energy saving gain cannot be obtained.
