Problems solved by technology

Due to the nature of the narrowband, POs may be repeated hundreds of times, resulting in a conflict between the SI-window and the timing of POs repeatedly sent by paging
[0007] Aiming at the problem of conflicting PO timing between SI-window and paging in related technologies, no effective solution has been proposed yet

Embodiment 1

[0049] In this embodiment, a method for determining a message window is provided, figure 2 is a flowchart of an optional method for determining a message window according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0050] Step S202, the base station configures the offset value of the SI-window, and / or configures the offset value and / or length of the PO-window according to the positional relationship between the system message window SI-window and the paging message window PO-window , where the PO-window is composed of POs that repeatedly send paging messages between two paging occasion POs that initially transmit paging messages;

[0051] Step S204, the base station sends the offset value of the SI-window, and / or the offset value and / or length of the PO-window to the user equipment UE.

[0052] Optionally, the above steps may be applied in a communication scenario, but are not limited to. Especially in ...

Embodiment 2

[0071] In this embodiment, a method for determining a message window is provided, image 3 is a flow chart of another optional method for determining a message window according to an embodiment of the present invention, such as image 3 As shown, the process includes the following steps:

[0072] Step S302, the UE receives the offset value of the system message window SI-window sent by the base station, and / or the offset value of the paging message window PO-window, wherein, the offset value of the SI-window, and / or, the configured The offset value of the PO-window is configured by the base station according to the positional relationship between the SI-window and the PO-window. The PO-window consists of the PO that repeatedly sends the paging message between the two paging timing POs that initially transmit the paging message. composition;

[0073] In step S304, the UE determines the position of the SI-window and / or the PO-window according to the offset value of the SI-wind...

Embodiment approach 1

[0093] This optional implementation manner provides a method for configuring an SI-window offset value. The method comprises the steps of:

[0094] In the LTE system, multiple SIBs with the same period are mapped to the same SI for unified scheduling. SIB1 carries the scheduling information of all SIs, and the starting radio frame position for the nth SI (SI-n) is:

[0095] SFN mod T=Floor(x / 10)

[0096] Wherein, SFN is the starting radio frame position, T is the transmission period, x=(n-1)*w, w is the size of the SI window, and Floor points to the rounded down.

[0097] Configuring an offset value for the SI-window can avoid conflicts between the SI-window and the PO that is sent repeatedly in the paging message. The method for configuring the SI-window offset value for the SI-window may be to configure the same SI-window offset value for all SIs; or to configure different or not completely identical SI-window offset values ​​for each SI. In addition, the configured SI-w...

Abstract

The invention provides a method, device and system for determining a message window. Wherein, the method includes: the base station configures the offset value of the SI-window according to the positional relationship between the system message window SI-window and the paging message window PO-window, and / or configures the offset value of the PO-window and / or length, where PO-window is composed of POs that repeatedly send paging messages between two paging occasions POs that initially transmit paging messages; the base station uses the offset value of SI-window, and / or, the PO-window The offset value and / or length are sent to the user equipment UE. The present invention solves the problem of conflicts between SI-window and PO timings that are repeatedly sent by paging, thereby avoiding conflicts between SI-window and PO timings that are repeatedly sent by paging.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system for determining a message window. Background technique [0002] The rapid development of mobile Internet, Internet of Things, and other business applications has become the main driving force for the development of the fifth generation mobile communication technology (5G). They urgently require 5G to have an access rate comparable to optical fiber, a connection capability of hundreds of billions of devices, a perfect real-time experience, and wireless broadband access anytime, anywhere. In addition, important indicators such as energy efficiency, spectrum efficiency, and peak rate also need to be considered comprehensively in the design of 5G systems. In 2013, China established the IMT-2020 (5G) promotion group to promote the development of 5G technology. According to the overall international situation, it is expected that 5G vision, key capabilit...
