Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technology, and more particularly to a method, an apparatus and a readable storage medium for determining an initial paging frame corresponding to a PEI. [Background technology]

[0002] In wireless communication technology, for example, in 5th Generation Mobile Communication Technology (5G), when user equipment is in the RRC idle state (Radio Resource Control IDLE, RRC-IDLE) or the RRC inactive state (RRC-INACTIVE), periodic monitoring paging messages are required. After monitoring the paging messages, the UE enters the RRC connected state and can communicate normally with the network side. The paging messages are carried on the Physical Downlink Shared Channel (PDSCH) and can be scheduled by the Downlink Control Information (DCI).

[0003] For a UE, the corresponding paging occasion (PO) appears periodically, and the radio frame in which the paging occasion (PO) exists is called a paging frame (PF). A network device sends a paging early indication (PEI) to the UE to save energy consumption when the UE is in RRC idle state. The usage of the PEI is as follows: 1. The UE receives a PEI indication corresponding to this UE, and if this PEI indicates that the UE should wake up, the UE needs to wake up and monitor the paging message before the next paging occasion.

[0004] 2. The UE receives a PEI indication corresponding to this UE, and if this PEI does not indicate that the UE should be woken up, the UE does not need to wake up in the next paging cycle, i.e., the UE does not need to monitor the next paging occasion.

[0005] 3. If the UE does not receive a PEI indication corresponding to this UE, the UE does not need to wake up in the next paging cycle, i.e., the UE does not need to monitor the next paging occasion.

[0006] One PEI can correspond to one or multiple POs (the number of POs corresponding to one PEI can be determined by the high-level configuration parameter POnumPerPEI). These POs may be on one paging frame (PF) or may span multiple PFs (the maximum is two PFs).

[0007] How to position the first paging frame (also called the first PF) corresponding to the PEI is a technical problem to be solved. Summary of the Invention [Problem to be solved by the invention]

[0059] In a possible embodiment, the terminal device or the network device can determine the first paging frame corresponding to the PEI based on the number of POs corresponding to the PEI and the number of POs in one paging frame.

[0060] In an embodiment of the present disclosure, a network device, a user equipment, determines the first paging frame corresponding to a PEI based on the PO corresponding to each PEI and the number of POs in one paging frame, providing a premise for determining the location of the PEI, so that the location of the PEI can be accurately determined, allowing the user equipment to accurately receive the PEI DCI, and improving communication efficiency.

[0061] An embodiment of the present disclosure provides a method for determining an initial paging frame corresponding to a PEI, and the method is performed by a user equipment 102 or a network device 101. Figure 3 is a flowchart of a method for determining an initial paging frame corresponding to a PEI according to an exemplary embodiment. As shown in Figure 3, the method includes the following steps: Step S301: determine an initial paging frame corresponding to a paging early indication (PEI) based on one or more paging occasions (PO) corresponding to the PEI and the number of POs in one paging frame PF;

[0062] In a possible embodiment, determining the initial paging frame refers to determining the SFN of the initial paging frame.

[0064] In a possible embodiment, the terminal device and the network device can determine the first paging frame corresponding to the PEI based on the number of POs corresponding to the PEI and the number of POs in one paging frame.

[0065] In the embodiments of the present disclosure, a paging early indication (PEI) can correspond to one or more paging occasions (POs), and the PEI can correspond to one or more paging frames. Therefore, a network device and / or user equipment can determine the first paging frame corresponding to the PEI based on the PO corresponding to the PEI and the number of POs in one paging frame, which provides a premise for determining the location of the PEI, allowing the location of the PEI to be accurately determined, allowing the user equipment to accurately receive the PEI DCI, and improving communication efficiency.

[0066] An embodiment of the present disclosure provides a method for determining an initial paging frame corresponding to a PEI, and the method is performed by a user equipment 102 or a network device 101. Figure 4 is a flowchart of a method for determining an initial paging frame corresponding to a PEI according to an exemplary embodiment. As shown in Figure 4, the method includes the following steps: Step S401: The number of POs corresponding to the PEI is equal to the number N of POs in one paging frame. s In response to: determining that the paging frame in which a paging occasion (PO) monitored by the user equipment exists is the first paging frame corresponding to the PEI;

[0067] In a possible example, taking FIG. 5 as an example, the SFN cycles from 0 to 1024. T=128, that is, the value of the paging cycle of the user equipment is 128, or the paging cycle of the user equipment is understood to be 128 system radio frames. One paging cycle includes, for example, 16 paging frames PF. In one PF, Ns It can contain N POs. s = 2, that is, the number of paging occasions in one paging frame is 2, or one paging frame is understood to include two paging occasions. POnumPerPEI = 2, that is, the number of POs corresponding to a PEI, POnumPerPEI, is 2. After the UE receives a PEI indication, if the PEI indicates that the UE should be woken up, the UE needs to monitor the PO corresponding to the PEI and corresponding to this UE. Since POnumPerPEI≦Ns holds, the UE can determine the first paging frame corresponding to the PEI, that is, the paging frame in which the PO monitored for this UE exists. That is, In the related art, different paging frames in one paging cycle correspond to different UEs.

[0068] In a possible embodiment, the network device determining the initial paging frame refers to the network device determining the SFN of the initial paging frame.

[0069] In an embodiment of the present disclosure, the network device or user equipment may determine whether the number of one or more paging occasions (PO) corresponding to the paging early indication (PEI) is N. s If it is equal to or less than, it is determined that the system frame number (SFN) of the first paging frame in one or more paging frames corresponding to the PEI is the paging frame in which the paging occasion monitored by the user equipment exists, thereby accurately determining the location of the PEI, allowing the user equipment to accurately receive the PEI DCI, and improving communication efficiency.

As shown in Figure 6, the method includes the following steps: Step S601: The number of POs corresponding to the PEI is equal to the number N of POs in one paging frame. s In response to the PEI being greater, calculating a second value based on the following formula:

[0072] Taking Figure 5 as an example, in a possible example, the SFN is cyclically rotated by 1024, T=128, and the value of the paging cycle of the user equipment is 128, that is, the paging cycle of the user equipment is 128 system radio frames. Based on the SFN determination formula of the PF, the UE determines that the SFNs to which the PF corresponds are 8, 136, 264, 392, 520, 648, 776, and 904 (SFN is cyclically rotated by 1024).

[0073] The network device configures one paging cycle to contain 16 paging frames. s = 2, that is, the number of POs in one paging frame is 2, or one paging frame contains two paging occasions. POnumPerPEI = 4, that is, the number of POs corresponding to PEI, POnumPerPEI, is 4. Since POnumPerPEI = 4, the condition POnumPerPEI > N sThe UE may determine that the relative PO index (counting from 0) i of one or more POs corresponding to the UE-monitored PEI of the PO monitored by the UE based on Equation (1). po Calculate
