FIG. 4 is a schematic diagram of a method for distinguishing a paging message according to the embodiment of the present application in the scenario of FIG. 3. The method for distinguishing a paging message according to an embodiment of the present application is described below with reference to FIGS. 3 and 4 by way of example.

As shown in FIG. 3, it is assumed that PF n corresponds to 4 POs. Specifically, PF n corresponds to 4 POs, as shown in FIG. 3, with the number i_s = 0, the number i_s = 1, and the number i_s. = 2 PO, numbered i_s = 3 PO. Suppose PF n + 1 corresponds to 4 POs. Specifically, PF n + 1 corresponds to 4 POs, as shown in FIG. 3, i_s = 0 'PO, i_s = 1' PO, and i_s. = 2 'PO, numbered i_s = 3' PO. Among them, O1, O2, O3, and O4 shown in FIG. 3 are time offsets of the start time of the configured 4 POs relative to the start time of the PF n.

Further, it is assumed that the paging frame corresponding to UE1 is PF n and the paging frame corresponding to UE2 is PF n + 1.

As shown in FIG. 3, it is assumed that UE1 corresponding to PF n with i_s = 2 has no paging message in this paging cycle, but UE2 corresponding to PF n + 1 with i_s = 0 has a paging message. Send. Since the PO corresponding to PF n with i_s = 2 and the PO corresponding to PF n + 1 with i_s = 0 'overlap in time, the network that UE1 may receive at this time was originally in the corresponding PF n + 1 and The DCI of the scheduling paging message sent in the PO with the number i_s = 0 ', UE1 mistakenly thought that it had sent its paging message, and then received the scheduled paging message PDSCH, but eventually could not paging the paging list in the PDSCH Find the paging message corresponding to UE1 in this way, which leads to waste of power consumption of UE1 receiving the paging message.

In the embodiment of the present application, the paging-radio network temporary identifier (P-RNTI) is scrambled through the scheduling information in different time segments using different paging-radio network temporary identifiers, thereby making the terminal The device can distinguish the scheduling information of paging messages that overlap in time but correspond to two different PFs respectively, and then receive the paging messages correctly.

For example, as shown in FIG. 4, in the embodiment of the present application, the PO corresponding to PF n is i_s = 0, and the PO corresponding to i_s = 1 is P-RNTI 1. The number corresponding to PF n is i_s = 2, i_s = 3. The PO uses P-RNTI2. Similarly, the PO corresponding to PF n + 1 is i_s = 0 'and the PO corresponding to i_s = 1' is P-RNTI1, and the PO corresponding to PF n + 1 is i_s = 2 'and the PO corresponding to i_s = 3' is adopted P-RNTI 2. Further, assuming that PF n corresponds to UE1 and PF n + 1 corresponds to UE2, UE1 may use P-RNTI 2 to descramble the scheduling information of the paging message of UE1 on the PO numbered i_s = 2 and i_s = 3, UE2 may use P-RNTI1 to descramble the scheduling information of the paging message of UE2 on the POs with the numbers i_s = 0 'and i_s = 1'. It can be found that, based on the above technical solutions, even if the PO corresponding to PF n with i_s = 2 and the PO corresponding to PF n + 1 with i_s = 0 'overlap or partially overlap, the number corresponding to PF n with i_s = 3 The PO with PF n corresponding to the number i_s = 1 'overlaps or partially overlaps.
