Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and device.

Background

The base station may send a paging message to a User Equipment (UE), where the paging message may be used to notify the UE to receive a paging request, update system information, or notify the UE to receive an earthquake and tsunami warning system or a commercial mobile alert service. For energy saving, paging Reception of the UE follows the principle of Discontinuous Reception (DRX). In the New Radio (NR), the UE is under the coverage of different beams (beam), and when the beam direction of the UE is unknown, the base station may transmit a paging message to the UE in a beam scanning (beam sweep) manner, that is, the base station transmits the paging message in all beam directions of the UE, in order to ensure that the UE can receive the paging message.

The conventional configuration method may be: in the same DRX cycle, the base station needs to page multiple UEs, and each UE has only one Paging Occasion (PO) in the DRX cycle. The length of each PO is a period of beam sweep, wherein the PO takes a time slot as a unit, and the DRX period is set to be integral multiple of the beam sweep period. POs are in units of slots, which results in that the length of a PO may not be an integer number of subframes and the location of different POs within different frames is irregular. Because the time information in the communication System is broadcasted in the System Frame Number (SFN), the UE can know that the paging message of the UE is at the kth PO, but still cannot know that the kth PO is located in the several subframes of the several frames, so that the UE cannot accurately identify the position of the PO.

Disclosure of Invention

The technical problem to be solved by the embodiments of the present application is to provide a communication method and device, which can facilitate a second device to accurately identify a PO location.

In a first aspect, an embodiment of the present application provides a communication method, including: the first device obtains a first number of time units contained in a PO and a second number of frames contained in a Paging Frame (PF), obtains information of the PO according to the first number and the second number, and sends a Paging message to the second device at the PO indicated by the information of the PO.

In this technical solution, the first device may obtain information of the POs according to the first number of the time units included in the PO and the second number of the frames included in the PF, and then send the paging message to the second device at the PO indicated by the information of the PO, and then the second device may obtain information of the PO according to the first number of the time units included in the PO and the second number of the frames included in the PF, and then receive the paging message at the PO indicated by the information of the PO. In contrast to conventional communication methods, the PO is in units of slots, which results in that the length of the PO may not be an integer number of subframes, and the positions of different POs in different frames are irregular. Since the time information in the communication system is broadcasted in the SFN, the second device may know that the paging message of the second device is at the kth PO, but still may not know that the kth PO is located in the several subframes of the several frames, so that the UE may not accurately identify the location of the PO. However, the embodiments of the present application introduce the concept of PFs, where one DRX cycle may include at least one PF, one PF may include at least one PO, and the second number of frames included in the PF and the first number of time units included in the PO are dynamically expandable, the first device may obtain information of the POs according to the first number and the second number, and the information of the PO may include time information for sending a paging message of the second device, for example, the information of the PO may be used to indicate that a paging message is transmitted in a several time units of a several frames in the DRX cycle, and the second device may receive the paging message at the PO indicated by the information of the PO, which may facilitate the second device to accurately identify the position of the PO in the DRX cycle, and improve the accuracy of receiving the paging message.

In one design, the PF may include two or more consecutive frames. For example, each PF within a DRX cycle may include 2 consecutive frames, 3 consecutive frames, or 5 consecutive frames, etc.

In this design, if the PF includes two or more consecutive frames, the length of each PF may be increased, the first number of time units included in each PO located in the PF may be increased, and the first device may send the paging message in the plurality of beam directions of the second device, so as to ensure that the second device can accurately receive the paging message, and improve reliability of transmission of the paging message. For example, in order to ensure that the second device can receive the paging message when the second device is under coverage of different beams in the NR scenario and the beam direction of the second device is unknown, the first device may send the paging message to the second device in a beam sweep manner, that is, the first device sends the paging message to all beam directions of the second device in a PO including at least two time units.

In one design, after obtaining the second number of frames included in the PF, the first device may determine a start frame included in the PF, and determine the start frame and at least one frame after the start frame as the PF, where the number of the start frame and at least one frame after the start frame is the same as the second number.

In the design scheme, the first device may determine the start frame included in the PF by using the configuration method of the PF in the LTE system, and determine the start frame and at least one frame after the start frame as the PF. For example, the first device obtains that the second number of frames included in the PF is 2, and based on the configuration method of the PF in the LTE system, it may be determined that the start frame included in the PF is located in the first frame in the DRX cycle in this application, and then the first device may determine the first frame and the second frame in the DRX cycle as the PF.

In one design, the first device may determine that the PO is located in the PF from first to nth time cells, from 10 × k × m/2-n +1 to 10 × k × m/2 time cells, from 10 × k × m/2+1 to 10 k × m/2+ n time cells, or from 10 k × m-n +1 to 10 × k × m time cells, where n is the first number, m is the second number, and k is a positive integer.

In this design, when the time unit is a subframe, k is 1; and when the time unit is a time slot, k is a third number of time slots contained in each preconfigured subframe. For example, if k is 1, m is 2, and n is 2, and four POs are included in the PF, a first PO may be located in the first and second subframes of the PF, a second PO may be located in the ninth and tenth subframes of the PF, a third PO may be located in the eleventh and twelfth subframes of the PF, and a fourth PO may be located in the nineteenth and tenth subframes of the PF. Compared with the uniform distribution of the POs in the PF, in the present application, the interval between the first PO and the second PO is longer, and the interval between the third PO and the fourth PO is longer, which may facilitate the first device to configure the special subframe in the time unit other than the PO in the PF.

In one design, the first device may determine that the PO is located in the PF from the first to the nth time cells, from the 10 × k × m/4+1 to the 10 × k × m/4+ n time cells, from the 10 × k × m/2+1 to the 10 k × m/2+ n time cells, or from the 10 k m 3/4+1 to the 10 × k m 3/4+ n time cells, where m is the second number, n is the first number, and k is a positive integer.

In this design, when the time unit is a subframe, k is 1; and when the time unit is a time slot, k is a third number of time slots contained in each preconfigured subframe.

In the technical scheme, the second number of frames contained in the PF does not need to be configured independently, so that the overhead can be saved. For example, if the first number of slots included in the PO is 10, and one subframe includes four slots in the NR, the first device may determine that the third number is 4, divide the first number by the third number, obtain a quotient of 2.5, and round up to 3, and determine that the PF includes three frames, that is, the second number of frames included in the PF is 3.

In this technical solution, the second device may obtain information of the PO according to the first number of time units included in the PO and the second number of frames included in the PF, and further receive the paging message at the PO indicated by the information of the PO. In contrast to conventional communication methods, the PO is in units of slots, which results in that the length of the PO may not be an integer number of subframes, and the positions of different POs in different frames are irregular. Since the time information in the communication system is broadcasted in the SFN, the second device may know that the paging message of the second device is at the kth PO, but still may not know that the kth PO is located in the several subframes of the several frames, so that the UE may not accurately identify the location of the PO.

In order to better understand a communication method, apparatus, and system disclosed in the embodiments of the present application, a network architecture to which the embodiments of the present application are applicable is first described below. Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 1, the communication system may include a first device 101 and at least one second device 102. The first device and the second device may establish data communication, the first device may send the first number of time units included in the PO to the second device through the data communication, the first device may obtain information of the PO according to the first number of time units included in the PO and the second number of frames included in the PF, and send a paging message to the second device at the PO indicated by the information of the PO, the second device may receive the first number of time units included in the PO from the first device, obtain information of the PO according to the first number of time units included in the PO and the second number of frames included in the PF, and receive the paging message at the PO indicated by the information of the PO.

It should be noted that, in the specific embodiment of the present application, the second device is described by taking a UE in a general sense as an example.

Before describing specific embodiments of the present application, some brief descriptions will be made on the DRX, PF, PO and other concepts that may be involved in the present application. The paging reception of the second devices follows the DRX principle, i.e. the cell sends the DRX cycle of the cell to all second devices within the cell, and each second device can set the DRX of the second device based on its own power and paging system. In the same DRX cycle, the first device needs to send paging messages to different second devices at different POs, and only one PO of the first device sends paging messages to one second device in the DRX cycle. Wherein, one DRX period can comprise at least one PF, the PF is one frame or a plurality of continuous frames used for transmitting paging messages, and the number of frames contained in the PF is configurable. A PF may include at least one PO, the PO being a time unit for transmitting paging messages, the number of time units included in the PO being configurable. It should be noted that PO refers to a time period, for example, a time period included in the first frame in the PF, or a time period between the 41 th slot and the 48 th slot in the PF. The cell mentioned in the present invention may be a cell corresponding to a base station, and the cell may belong to a macro base station, or may belong to a base station corresponding to a small cell (small cell), where the small cell may include a city cell (Metro cell), a Micro cell (Micro cell), a Pico cell (Pico cell), a Femto cell (Femto cell), and the like, and these small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing a scenario of a high-rate data transmission service.

The first device may obtain information of the PF according to the number of frames included in the PF. The information of the PF may include time information of the PF including, but not limited to, a start time, a frame number, a slot number, an end time, a duration, and the like. The frame number may be a frame number of each frame included in the PF, or the frame number may be a frame number of the start frame included in the PF and a frame number of the end frame included in the PF.

The first device may obtain information of the PO according to the number of frames included in the PF and the number of time units included in the PO. The information of the PO may include time information of the PO including, but not limited to, a start time, a subframe number, a slot number, an end time, a duration, and the like. The subframe number may be a subframe number of each subframe included in the PO, or the subframe number may be a subframe number of a starting subframe included in the PO and a subframe number of an ending subframe included in the PO. The timeslot number may be the timeslot number of each timeslot included in the PO, or the timeslot number may be the timeslot number of the start timeslot included in the PO and the timeslot number of the end timeslot included in the PO.

A time unit may include a subframe or a slot. Wherein, one frame may include 10 subframes, and in the LTE system, one subframe may include 2 slots; in NR, one subframe may include 2 slots, 4 slots, 6 slots, 8 slots, or the like.

Based on the schematic architecture of the communication system shown in fig. 1, please refer to fig. 2, and fig. 2 is a communication method provided in the embodiment of the present application, which includes, but is not limited to, the following steps:

step S201: and the base station sends the first number of the subframes contained in the PO and the second number of the frames contained in the PF to the UE through high-layer signaling or broadcast messages.

Wherein the first number and the second number are base station independently configurable.

Step S202: and the base station obtains the information of the PF according to the second quantity.

The base station may determine a start frame included in the PF, and determine the start frame and at least one frame after the start frame as the PF, where the number of the start frame and the at least one frame after the start frame is the same as the second number. For example, the second number is 3, the frame number of the initial frame included in the PF is 0, and if the information of the PF includes the frame number of the included frame, the base station may determine that the frame number is 0, 1, 2; if the information of the PF includes the frame number of the included start frame and the frame number of the end frame, the base station may determine that the frame number is 0, 2. It should be noted that, in the embodiment of the present application, the second number of frames included in the PF may be one, or may be multiple, and is not particularly limited by the embodiment of the present application, and when the second number of frames included in the PF is multiple, the frames included in the PF are consecutive frames, for example, two consecutive frames or more than two consecutive frames.

Specifically, the base station may determine the starting frame of the frame included in the PF based on the relevant parameter of the UE, and for example, the base station may calculate the starting frame of the frame included in the PF by the following formula:

SFNmodT＝(TdivN)*(UE_IDmodN)

where, SFN represents a frame Number of the start frame, T represents a DRX cycle, N ═ min (T, nB), nB may be 4T, 2T, T, T/2, T/4, T/8, T/16, or T/32, UE _ ID ═ IMSI mod 1024, and IMSI represents an International Mobile Subscriber identity Number (IMSI) of the UE.

Taking the structure diagram of the PF shown in fig. 8A as an example, when T is 16 frames, nB is T/4, and m is 2, the base station may determine that N is 4 and T div is 4 based on the above formula. If UE _ IDmodN is 0, the base station may determine that (TdivN) × (UE _ IDmodN) ═ 0, and the frame number of the start frame of the frame included in the PF is 0, that is, the start frame is located in the first frame in the DRX cycle, and then the base station may determine that the PF used for transmitting the paging message of the UE is located in the first frame and the second frame in the DRX cycle. If UE _ ID mod N is 1, the base station may determine that (TdivN) × (UE _ IDmodN) ═ 4, and the frame number of the start frame of the frame included in the PF is 4, that is, the start frame is located in the fifth frame in the DRX cycle, and then the base station may determine that the PF used for transmitting the paging message of the UE is located in the fifth frame and the sixth frame in the DRX cycle. If UE _ IDmodN is 2, the base station may determine that (TdivN) × (UE _ IDmodN) ═ 8, and the frame number of the start frame of the frame included in the PF is 8, that is, the start frame is located in the ninth frame in the DRX cycle, and then the base station may determine that the PF used for transmitting the paging message of the UE is located in the ninth frame and the tenth frame in the DRX cycle. If UE _ IDmodN is 3, the base station may determine that (TdivN) × (UE _ IDmodN) ═ 12, and the frame number of the start frame of the frame included in the PF is 12, that is, the start frame is located in the thirteenth frame in the DRX cycle, and then the base station may determine that the PF used for transmitting the paging message of the UE is located in the thirteenth frame and the fourteenth frame in the DRX cycle.

In one design, the DRX cycle includes a number of frames equal to or greater than a product of the second number and a number of PFs included in the DRX cycle. Taking fig. 8A as an example, T is 16 frames, that is, the number of frames included in the DRX is 16, and if the second number is 2, the number of PFs included in the DRX cycle needs to be less than or equal to 8.

Step S203: the base station obtains information of POs in the PF indicated by the information of the PF according to the first number, wherein the POs are continuously and non-uniformly distributed.

Specifically, the PO may be continuously or discontinuously distributed in the PF, and the PO may be uniformly or non-uniformly distributed in the PF. In order to facilitate setting of the special subframe in the PF, the base station may configure the POs in a continuous and non-uniformly distributed manner. The PO may be located in the PF from the first to the nth subframes, from the 10 × k × m/2-n +1 to the 10 × k × m/2 subframes, from the 10 × k × m/2+1 to the 10 × k × m/2+ n subframes, or from the 10 × k × m-n +1 to the 10 × k × m subframes, where n is the first number, m is the second number, and k is 1. Taking the schematic structure of the PO shown in fig. 8B as an example, if m is 2 and n is 2, the information of the PO includes the subframe number of the subframe included in the PO, where the subframe number is 0 and 1, the base station may determine that the PO is located in the first subframe and the second subframe in the PF. If the subframe number is 8, 9, the base station may determine that POs are located in the ninth subframe and the tenth subframe in the PF. If the subframe number is 10, 11, the base station may determine that the PO is located in the eleventh subframe or the twelfth subframe in the PF. If the subframe number is 18, 19, the base station may determine that the PO is located in the nineteenth subframe or the twenty subframes in the PF. It should be noted that the PO information includes, but is not limited to, the subframe number of the subframe included in the PO, and may also be the subframe number of the starting subframe and the subframe number of the ending subframe included in the PO. It should be noted that, in the embodiment of the present application, the first number of the subframes included in the PO may be one, or may be multiple, and is not specifically limited by the embodiment of the present application.

In one embodiment, the product of the first quantity and the predetermined first value is smaller than or equal to the product of the second quantity and the predetermined second value. For example, a frame may include 10 subframes, a PF may include 4 POs at most, and the preset first value may be 4 and the preset second value may be 10, i.e., 4 × n ≦ 10 × m.

In one design, when the calculated PF includes one PO, the first device may obtain a PO id of the second device, and when the PO id of the second device is the first id, the first device may determine that the PO is located in the 10 × k × m-n +1 to 10 × k × m subframes in the calculated PF. Wherein k is 1.

In one design, when the calculated PF includes two POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located in the first to nth subframes in the calculated PF; when the PO identifier of the second device is the second identifier, the first device may determine that the PO is located in the 10 × k × m-n +1 to 10 × k × m subframes in the calculated PF. Wherein k is 1.

In one design, when the calculated PF includes four POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located in the 10 × k × m/2+1 to 10 × k × m/2+ n subframes of the calculated PF; when the PO identifier of the second device is the second identifier, the first device may determine that the PO is located in the 10 × k × m/2-n +1 to 10 × k × m/2 subframes in the calculated PF; when the PO identifier of the second device is the third identifier, the first device may determine that the PO is located in the first to nth subframes in the calculated PF; when the PO identifier of the second device is the fourth identifier, the first device may determine that the PO is located in the 10 × k × m-n +1 to 10 × k × m subframes in the calculated PF. Wherein k is 1.

Specifically, the base station may determine the PO identifier based on the relevant parameters of the UE, and for example, the base station may calculate the PO identifier according to the following formula:

i_s＝floor(UE_ID/N)mod Ns

where i _ s represents a PO identity of the UE, UE _ ID is IMSI mod 1024, IMSI represents IMSI of the UE, N is min (T, nB), T represents a DRX cycle, nB may be 4T, 2T, T, T/2, T/4, T/8, T/16, or T/32, Ns is max (1, nB/T), and Ns may represent the number of POs included in one PF.

For example, the corresponding relationship between the PO id and the PO information can be as shown in table one:

watch 1

When the PF includes a PO and the PO is identified as 0, the information of the PO may include a duration, for example, 10 × m-n +1 to 10 × m subframes in the PF. When the PF includes two POs, and the PO is identified as 0, the information of the PO may include a duration, for example, first to nth subframes in the PF; when the PO is denoted by 1, the information of the PO may be the 10 th m-n +1 to 10 th m subframes in the PF. When the PF includes four POs and the PO is identified as 0, the information of the POs may include a duration, for example, 10 × m/2+1 to 10 × m/2+ n subframes in the PF; when the PO id is 1, the information of the PO may be the 10 th m/2-n +1 to 10 th m/2 subframes in the PF; when the PO identifier is 2, the information of the PO may be first to nth subframes in the PF; when the PO is identified as 3, the information of the PO may be the 10 th m-n +1 to 10 th m subframes in the PF.

It should be noted that, the correspondence between the PO identifier and the PO information in the embodiment of the present application includes, but is not limited to, the above manner, for example, when the PF includes four POs and the PO identifier is 0, the PO information may include a duration, for example, 10 × m-n +1 to 10 × m subframes in the PF; when the PO identifier is 1, the information of the PO may be first to nth subframes in the PF; when PO is identified as 2, the information of PO may be the 10 th m/2-n +1 to 10 th m/2 subframes in PF; when PO is denoted by 3, the information of PO may be the 10 th m/2+1 to 10 th m/2+ n subframes in PF.

Step S204: and the UE obtains the information of the PF according to the second quantity.

Before the UE receives the paging message, it needs to acquire information of the PO, and then receives the paging message at the PO indicated by the information of the PO. It should be noted that, in the embodiment of the present application, an implementation manner of the UE acquiring the information of the PF is the same as an implementation manner of the base station acquiring the information of the PF, and then step S204 may specifically refer to the description of step S202, which is not described again in the embodiment of the present application.

Step S205: and the UE obtains the information of the PO in the PF indicated by the information of the PF according to the first number.

It should be noted that, in the embodiment of the present application, an implementation manner of acquiring PO information by the UE is the same as an implementation manner of acquiring PO information by the base station, and reference may be specifically made to the description of step S203 in step S205, which is not described again in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the execution order of step S204 and step S205 in fig. 2 is not limited, and after the UE receives the first number of subframes included in the PO and the second number of frames included in the PF from the base station, step S204 and step S205 may be executed, for example, step S204 and step S205 may be executed before or after step S202, before or after step S203, or before or after step S206.

Step S206: the base station transmits the paging message to the UE at the PO indicated by the PO information, wherein the POs are continuously non-uniformly distributed.

After obtaining the information of the PO, the base station may send a paging message to the UE at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the nineteenth subframe and the twentieth subframe in the PF, the base station may send a paging message to the UE in the nineteenth subframe and the twentieth subframe in the DRX cycle.

By the embodiment of the application, the base station can send the paging message to the UE in at least one beam direction of the UE so as to ensure that the UE can accurately receive the paging message and improve the transmission reliability of the paging message.

In one design, after obtaining the information of the PO, the UE may receive the paging message at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the nineteenth subframe and the twentieth subframe in the PF, the UE may receive the paging message in the nineteenth subframe and the twentieth subframe in the DRX cycle.

In the method illustrated in fig. 2, the base station sends, to the UE, the first number of subframes included in the PO and the second number of frames included in the PF through a high layer signaling or a broadcast message, and the base station obtains information of the PO according to the first number and the second number, and sends, to the UE, a paging message at the PO indicated by the information of the PO, so that the UE can obtain the information of the PO according to the first number and the second number, and receive, at the PO indicated by the information of the PO, the paging message, which can facilitate the second device to accurately identify the location of the PO.

Based on the schematic architecture of the communication system shown in fig. 1, please refer to fig. 3, and fig. 3 is a communication method provided in the embodiment of the present application, which includes, but is not limited to, the following steps:

step S301: the base station transmits the first number of slots included in the PO and the second number of frames included in the PF to the UE through a higher layer signaling or a broadcast message.

Step S302: and the base station obtains the information of the PF according to the second quantity.

It should be noted that step S302 may specifically refer to the description of step S202, and the embodiments of the present application are not described again.

Step S303: the base station obtains information of the POs in the PF indicated by the information of the PF according to the first number.

Specifically, the PO may be continuously or discontinuously distributed in the PF, and the PO may be uniformly or non-uniformly distributed in the PF. In order to facilitate setting of the special subframe in the PF, the base station may configure the POs in a continuous and non-uniformly distributed manner. PO may be located in the PF from the first to nth slots, from 10 × k × m/2-n +1 to 10 × k × m/2 slots, from 10 × k × m/2+1 to 10 × k × m/2+ n slots, or from 10 × k × m-n +1 to 10 × k × m + 2, where n is a first number, m is a second number, and k is used to represent a third number of slots contained in each subframe, e.g., k is 2 when a subframe includes two slots; when one subframe includes 4 slots, k is 4; when one subframe includes 6 slots, k is 6; when one subframe includes 8 slots, k is 8. Taking the schematic structure of the PO shown in fig. 8C as an example, if m is 1, k is 2, and n is 2, the information of the PO includes the timeslot number of the timeslot included in the PO, where the timeslot number is 0 and 1, the base station may determine that the PO is located in the first timeslot and the second timeslot in the PF. If the slot number is 8, 9, the base station may determine that the PO is located in the ninth slot and the tenth slot of the PF. If the slot number is 10, 11, the base station may determine that the PO is located in the eleventh slot or the twelfth slot in the PF. If the slot number is 18, 19, the base station may determine that the PO is located in the nineteenth slot or the twentieth slot in the PF. It should be noted that the information of the PO includes, but is not limited to, the slot number of the slot included in the PO, and may also be the slot number of the starting slot and the slot number of the ending slot included in the PO, and so on. It should be noted that, in the embodiment of the present application, the first number of timeslots included in the PO may be one, or may be multiple, and is not specifically limited by the embodiment of the present application.

In one embodiment, the product of the first quantity and the predetermined first value is smaller than or equal to the product of the second quantity and the predetermined second value. For example, a frame may include 10 subframes, a subframe may include k slots, and a PF may include 4 POs at most, and the preset first value may be 4, and the preset second value may be 10 × k, that is, 4 × n ≦ 10 × k × m.

In one design, when the calculated PF includes a PO, the first device may obtain a PO id of the second device, and when the PO id of the second device is the first id, the first device may determine that the PO is located in the 10 × k × m-n +1 to 10 × k × m slots in the calculated PF. Where k is the third number of slots contained in each subframe.

In one design, when the calculated PF includes two POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located in the first to nth slots in the calculated PF; when the PO identifier of the second device is the second identifier, the first device may determine that the PO is located in the 10 × k × m-n +1 to 10 × k × m slots in the calculated PF. Where k is the third number of slots contained in each subframe.

In one design, when the calculated PF includes four POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located in 10 × k × m/2+1 to 10 × k × m/2+ n slots in the calculated PF; when the PO identifier of the second device is the second identifier, the first device may determine that the PO is located in the 10 × k × m/2-n +1 to 10 × k × m/2 time slots in the calculated PF; when the PO identifier of the second device is the third identifier, the first device may determine that the PO is located in the first to nth slots in the calculated PF; when the PO id of the second device is the fourth id, the first device may determine that the PO is located in the 10 × k × m-n +1 to 10 × k × m slots in the calculated PF. Where k is the third number of slots contained in each subframe.

i_s＝floor(UE_ID/N)mod Ns

For example, the corresponding relationship between the PO id and the PO information can be as shown in table two:

watch two

When the PF includes a PO and the PO is identified as 0, the information of the PO may include a duration, for example, 10 × k × m-n +1 to 10 × k × m slots in the PF. When the PF includes two POs, and the PO is identified as 0, the information of the POs may include a duration, for example, first to nth slots in the PF; when PO is denoted by 1, the information of PO may be the 10 × k × m-n +1 to 10 × k × m slots in PF. When the PF contains four POs, and the POs is identified as 0, the information of the POs may include a duration, for example, 10 × k × m/2+1 to 10 × k × m/2+ n slots in the PF; when PO is denoted by 1, the information of PO may be the 10 × k × m/2-n +1 to 10 × k × m/2 time slots in PF; when the PO id is 2, the information of the PO may be the first to nth slots in the PF; when PO is denoted by 3, the information of PO may be the 10 × k × m-n +1 to 10 × k × m slots in PF.

It should be noted that, the correspondence between the PO identifier and the PO information in the embodiment of the present application includes, but is not limited to, the above manner, for example, when the PF includes four POs and the PO identifier is 0, the PO information may include a duration, for example, 10 × k × m-n +1 to 10 × k × m slots in the PF; when the PO identifier is 1, the information of the PO may be the first to nth slots in the PF; when PO is identified as 2, the information of PO may be the 10 × k × m/2-n +1 to 10 × k × m/2 time slots in PF; when PO is denoted by 3, the information of PO may be the 10 × k × m/2+1 to 10 × k × m/2+ n time slots in PF.

Step S304: and the UE obtains the information of the PF according to the second quantity.

Before the UE receives the paging message, it needs to acquire information of the PO, and then receives the paging message at the PO indicated by the information of the PO. It should be noted that, in the embodiment of the present application, an implementation manner of the UE acquiring the information of the PF is the same as an implementation manner of the base station acquiring the information of the PF, and then step S304 may specifically refer to the description of step S202, which is not described again in the embodiment of the present application.

Step S305: and the UE obtains the information of the PO in the PF indicated by the information of the PF according to the first number.

It should be noted that, in the embodiment of the present application, an implementation manner of acquiring PO information by the UE is the same as an implementation manner of acquiring PO information by the base station, and reference may be specifically made to the description of step S303 in step S305, which is not described again in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the execution order of step S304 and step S305 in fig. 3 is not limited, and after the UE receives the first number of timeslots included in the PO and the second number of frames included in the PF from the base station, step S304 and step S305 may be executed, for example, step S304 and step S305 may be executed before or after step S302, before or after step S303, or before or after step S306.

Step S306: the base station transmits the paging message to the UE at the PO indicated by the PO information, wherein the POs are continuously non-uniformly distributed.

After obtaining the information of the PO, the base station may send a paging message to the UE at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the nineteenth slot and the twentieth slot in the PF, the base station may send a paging message to the UE in the nineteenth slot and the twentieth slot in the DRX cycle.

In one design, after obtaining the information of the PO, the UE may receive the paging message at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the nineteenth slot and the twentieth slot in the PF, the UE may receive the paging message in the nineteenth slot and the twentieth slot in the DRX cycle.

In the method illustrated in fig. 3, the base station sends the first number of timeslots included in the PO and the second number of frames included in the PF to the UE through a high layer signaling or a broadcast message, and the base station obtains information of the PO according to the first number and the second number and sends a paging message to the UE at the PO indicated by the information of the PO, so that the UE can obtain the information of the PO according to the first number and the second number and receive the paging message at the PO indicated by the information of the PO, which can facilitate the second device to accurately identify the location of the PO.

Based on the schematic architecture of the communication system shown in fig. 1, please refer to fig. 4, and fig. 4 is a communication method provided in the embodiment of the present application, which includes, but is not limited to, the following steps:

Step S402: and the base station obtains the information of the PF according to the second quantity.

It should be noted that step S402 may specifically refer to the description of step S202, and the embodiment of the present application is not described again.

Step S403: the base station obtains information of the POs in the PF indicated by the information of the PF according to the first number.

Specifically, the PO may be continuously or discontinuously distributed in the PF, and the PO may be uniformly or non-uniformly distributed in the PF. Regardless of the special subframe setting, the base station may configure the POs in a continuous and evenly distributed manner. The PO may be located in the PF from the first to the nth subframes, from the 10 × k × m/4+1 to the 10 × k × m/4+ n subframes, from the 10 × k × m/2+1 to the 10 × k × m/2+ n subframes, or from the 10 × k × m 3/4+1 to the 10 × k m 3/4+ n subframes, where n is the first number, m is the second number, and k is 1. Taking the schematic structure of the PO shown in fig. 8D as an example, if m is 2 and n is 2, the information of the PO includes the subframe number of the subframe included in the PO, where the subframe number is 0 and 1, the base station may determine that the PO is located in the first subframe and the second subframe in the PF. If the subframe number is 5, 6, the base station may determine that POs are located in the sixth subframe and the seventh subframe in the PF. If the subframe number is 10, 11, the base station may determine that the PO is located in the eleventh subframe or the twelfth subframe in the PF. If the subframe number is 15, 16, the base station may determine that the PO is located in the sixteenth subframe or the seventeenth subframe in the PF. It should be noted that the PO information includes, but is not limited to, the subframe number of the subframe included in the PO, and may also be the subframe number of the starting subframe and the subframe number of the ending subframe included in the PO. It should be noted that, in the embodiment of the present application, the first number of the subframes included in the PO may be one, or may be multiple, and is not specifically limited by the embodiment of the present application.

Wherein k is 1.

i_s＝floor(10*m div Ns)*(floor(UE_ID/N)mod Ns)

where i _ s represents a PO ID of the UE, m represents a second number, Ns ═ max (1, nB/T), Ns may represent the number of POs included in one PF, UE _ ID ═ IMSI mod 1024, IMSI represents an IMSI of the UE, N ═ min (T, nB), T represents a DRX cycle, and nB may be 4T, 2T, T, T/2, T/4, T/8, T/16, or T/32.

For example, the corresponding relationship between the PO id and the PO information can be as shown in table three:

When the PF includes one PO and the PO identifier is 0, the information of the PO may include a duration, for example, first to nth subframes in the PF. When the PF includes two POs, and the PO is identified as 0, the information of the PO may include a duration, for example, first to nth subframes in the PF; when the PO id is 1, the information of the PO may be the 10 th m/2+1 to 10 th m/2+ n subframes in the PF. When the PF includes four POs, and the PO is identified as 0, the information of the POs may include a duration, for example, first to nth subframes in the PF; when the PO is identified as 1, the information of the PO may be the 10 th m/4+1 to 10 th m/4+ n subframes in the PF; when PO is identified as 2, the information of PO may be the 10 th m/2+1 to 10 th m/2+ n subframes in PF; when the PO is denoted by 3, the information of the PO may be the 10 × m 3/4+1 to 10 × m 3/4+ n subframes in the PF.

It should be noted that, the correspondence between the PO identifier and the PO information in the embodiment of the present application includes, but is not limited to, the above manner, for example, when the PF includes four POs and the PO identifier is 0, the PO information may include a duration, for example, 10 × m 3/4+1 to 10 × m 3/4+ n subframes in the PF; when the PO is identified as 1, the information of the PO may be the 10 th m/2+1 to 10 th m/2+ n subframes in the PF; when the PO is identified as 2, the information of the PO may be the 10 th m/4+1 to 10 th m/4+ n subframes in the PF; when the PO id is 3, information of the PO may be first to nth subframes in the PF.

Step S404: and the UE obtains the information of the PF according to the second quantity.

Before the UE receives the paging message, it needs to acquire information of the PO, and then receives the paging message at the PO indicated by the information of the PO. It should be noted that, in the embodiment of the present application, an implementation manner of the UE acquiring the information of the PF is the same as an implementation manner of the base station acquiring the information of the PF, and then step S405 may specifically refer to the description of step S202, which is not described again in this embodiment of the present application.

Step S405: and the UE obtains the information of the PO in the PF indicated by the information of the PF according to the first number.

It should be noted that, in the embodiment of the present application, an implementation manner of acquiring PO information by the UE is the same as an implementation manner of acquiring PO information by the base station, and reference may be specifically made to the description of step S403 in step S406, which is not described again in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the execution order of steps S404 and S405 in fig. 4 is not limited, and after the UE receives the first number of subframes included in the PO and the second number of frames included in the PF from the base station, step S404 and step S405 may be executed, for example, step S404 and step S405 may be executed before or after step S402, before or after step S403, or before or after step S406.

Step S406: the base station sends the paging message to the UE at the PO indicated by the PO information, and the POs are continuously and uniformly distributed.

After obtaining the information of the PO, the base station may send a paging message to the UE at the PO indicated by the information of the PO. For example, if the PF is the first frame and the second frame in the DRX cycle, and the PO information is the first subframe and the second subframe in the PF, the base station may send the paging message to the UE in the first subframe and the second subframe in the DRX cycle.

In one design, after obtaining the information of the PO, the UE may receive the paging message at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in DRX cycle, and PO information is the first subframe and the second subframe in PF, the UE may receive the paging message in the first subframe and the second subframe in DRX cycle.

In the method illustrated in fig. 4, the base station sends, to the UE, the first number of subframes included in the PO and the second number of frames included in the PF through a high layer signaling or a broadcast message, and the base station obtains information of the PO according to the first number and the second number, and sends, to the UE, a paging message at the PO indicated by the information of the PO, so that the UE can obtain the information of the PO according to the first number and the second number, and receive, at the PO indicated by the information of the PO, the paging message, which can facilitate the second device to accurately identify the location of the PO.

Based on the schematic architecture of the communication system shown in fig. 1, please refer to fig. 5, and fig. 5 is a communication method provided in the embodiment of the present application, which includes, but is not limited to, the following steps:

Specifically, the PO may be continuously or discontinuously distributed in the PF, and the PO may be uniformly or non-uniformly distributed in the PF. Regardless of the special subframe setting, the base station may configure the POs in a continuous and evenly distributed manner. The PO may be located in the PF from the first to the nth slots, from 10 x k x m/4+1 to 10 x k x m/4+ n slots, from 10 x k x m/2+1 to 10 x k m/2+ n slots, or from 10 x k x m 3/4+1 to 10 k x m 3/4+ n slots, where n is the first number, m is the second number, and k is the third number of slots contained in each subframe. Taking the schematic structure of the PO shown in fig. 8E as an example, if m is 1, k is 2, and n is 2, the information of the PO includes the timeslot number of the timeslot included in the PO, where the timeslot number is 0 and 1, the base station may determine that the PO is located in the first timeslot and the second timeslot in the PF. If the slot number is 5, 6, the base station may determine that the PO is located in the sixth slot and the seventh slot in the PF. If the slot number is 10, 11, the base station may determine that the PO is located in the eleventh slot or the twelfth slot in the PF. If the slot number is 15, 16, the base station may determine that the PO is located in the sixteenth slot or the seventeenth slot in the PF. It should be noted that the information of the PO includes, but is not limited to, the slot number of the slot included in the PO, and may also be the slot number of the starting slot and the slot number of the ending slot included in the PO, and so on. It should be noted that, in the embodiment of the present application, the first number of timeslots included in the PO may be one, or may be multiple, and is not specifically limited by the embodiment of the present application.

i_s＝floor(10*m div Ns)*(floor(UE_ID/N)mod Ns)

For example, the corresponding relationship between the PO id and the PO information can be as shown in table four:

When the PF includes a PO and the PO identifier is 0, the information of the PO may include a duration, for example, the first to nth slots in the PF. When the PF includes two POs, and the PO is identified as 0, the information of the POs may include a duration, for example, first to nth slots in the PF; when PO is denoted by 1, the information of PO may be the 10 × k × m/2+1 to 10 × k × m/2+ n time slots in PF. When the PF includes four POs, and the PO is identified as 0, the information of the POs may include a duration, for example, first to nth slots in the PF; when PO is denoted by 1, the information of PO may be the 10 × k × m/4+1 to 10 × k × m/4+ n slots in PF; when PO is identified as 2, the information of PO may be the 10 × k × m/2+1 to 10 × k × m/2+ n slots in PF; when the PO is identified as 3, the information of the PO may be the 10 × k × m 3/4+1 to 10 × k × m 3/4+ n slots in the PF.

Step S504: and the UE obtains the information of the PF according to the second quantity.

Before the UE receives the paging message, it needs to acquire information of the PO, and then receives the paging message at the PO indicated by the information of the PO. It should be noted that, in the embodiment of the present application, an implementation manner of the UE acquiring the information of the PF is the same as an implementation manner of the base station acquiring the information of the PF, and then step S505 may specifically refer to the description of step S202, which is not described again in the embodiment of the present application.

Step S505: and the UE obtains the information of the PO in the PF indicated by the information of the PF according to the first number.

It should be noted that, in the embodiment of the present application, an implementation manner of acquiring PO information by the UE is the same as an implementation manner of acquiring PO information by the base station, and reference may be specifically made to the description of step S503 in step S506, which is not described again in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the execution order of step S504 and step S505 in fig. 5 is not limited, and after the UE receives the first number of timeslots included in the PO and the second number of frames included in the PF from the base station, step S504 and step S505 may be executed, for example, step S504 and step S505 may be executed before or after step S502, before or after step S503, or before or after step S506.

Step S506: the base station sends the paging message to the UE at the PO indicated by the PO information, and the POs are continuously and uniformly distributed.

After obtaining the information of the PO, the base station may send a paging message to the UE at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in DRX cycle, and PO information is the first slot and the second slot in PF, the base station may send the paging message to the UE in the first slot and the second slot in DRX cycle.

In one design, after obtaining the information of the PO, the UE may receive the paging message at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in DRX cycle, and PO information is the first slot and the second slot in PF, the UE may receive the paging message in the first slot and the second slot in DRX cycle.

In the method illustrated in fig. 5, the base station sends the first number of timeslots included in the PO and the second number of frames included in the PF to the UE through a high layer signaling or a broadcast message, and the base station obtains information of the PO according to the first number and the second number and sends a paging message to the UE at the PO indicated by the information of the PO, so that the UE can obtain the information of the PO according to the first number and the second number and receive the paging message at the PO indicated by the information of the PO, which can facilitate the second device to accurately identify the location of the PO.

Referring to fig. 6 based on the schematic architecture diagram of the communication system shown in fig. 1, fig. 6 is a communication method provided in the embodiment of the present application, where the method includes, but is not limited to, the following steps:

Wherein the first number is base station independently configured.

Step S602: the base station determines the first number as a second number of frames contained by the PF.

Specifically, in the embodiment of the present application, the POs are discontinuously distributed in the PF, and a configuration manner of the PO in each frame included in the PF is the same as a configuration manner of the PO in the LTE system. Wherein, the PO in the LTE system includes one subframe, the base station may determine that the PO includes one subframe in each frame included in the PF, that is, the second number of frames included in the PF is the same as the number of subframes included in the PO, and the base station may determine the first number as the second number of frames included in the PF.

Step S603: and the base station obtains the information of the PF according to the second quantity.

It should be noted that step S603 may specifically refer to the description of step S202, and the embodiments of the present application are not described again.

Step S604: the base station obtains information of the POs in the PF indicated by the information of the PF according to the first number.

The PO may be located at the 10 × ks +1 subframe, the 10 × ks +5 subframe, the 10 × ks +6 subframe, or the 10 × ks +10 subframe in the PF. Where s is 0, 1, 2 … m-1, m is the second number and k is 1. Taking the schematic structure of the PO shown in fig. 8F as an example, if m is 2 and n is 2, the information of the PO includes the subframe number of the subframe included in the PO, where the subframe number is 0 and 10, the base station may determine that the PO is located in the first subframe and the eleventh subframe in the PF. If the subframe number is 4, 14, the base station may determine that POs are located in the fifth and fifteenth subframes in the PF. If the subframe number is 5, 15, the base station may determine that the PO is located in the sixth subframe or the sixteenth subframe in the PF. If the subframe number is 9, 19, the base station may determine that the PO is located in the tenth subframe or the twenty subframes in the PF. It should be noted that the PO information includes, but is not limited to, the subframe number of the subframe included in the PO, and may also be the subframe number of the starting subframe and the subframe number of the ending subframe included in the PO. It should be noted that, in the embodiment of the present application, the first number of the subframes included in the PO may be one, or may be multiple, and is not specifically limited by the embodiment of the present application.

Wherein k is 1.

In one design, when the calculated PF includes four POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located in the 10 × ks +1 th subframe in the calculated PF; when the PO identifier of the second device is the second identifier, the first device may determine that the PO is located in the 10 × k × s +5 th sub-frames in the calculated PF; when the PO identifier of the second device is the third identifier, the first device may determine that the PO is located in the 10 × k × s +6 th sub-frames in the calculated PF; when the PO identity of the second device is the fourth identity, the first device may determine that the PO is located in the 10 × k × s +10 subframes of the calculated PF. Wherein k is 1.

i_s＝floor(UE_ID/N)mod Ns

For example, the corresponding relationship between the PO id and the PO information can be as shown in table five:

watch five

Ns	PO when i_s＝0	PO when i_s＝1	PO when i_s＝2	PO when i_s＝3
					1	10 th +10 th sub-frame	N/A	N/A	N/A
2	Sub-frame of 10 s +5	10 th +10 th sub-frame	N/A	N/A
					4	Sub-frame of 10 s +1	Sub-frame of 10 s +5	Sub-frame of 10 s +6	10 th +10 th sub-frame

When the PF includes one PO and the PO is identified as 0, the information of the PO may include a duration, for example, 10 × s +10 subframes in the PF. When the PF contains two POs, and the PO is identified as 0, the information of the PO may include a duration, for example, 10 × s +5 subframes in the PF; when the PO flag is 1, the information of the PO may be the 10 th × s +10 subframes in the PF. When the PF contains four POs, and the PO is identified as 0, the information of the POs may include a duration, for example, 10 × s +1 th subframe in the PF; when the PO identifier is 1, the information of the PO may be the 10 th × s +5 th subframe in the PF; when PO is identified as 2, the information of PO may be the 10 th × s +6 th subframe in PF; when PO is identified as 3, the information of PO may be the 10 th × s +10 subframes in PF.

It should be noted that, the correspondence between the PO identifier and the PO information in the embodiment of the present application includes, but is not limited to, the above manner, for example, when the PF includes four POs and the PO identifier is 0, the PO information may include a duration, for example, 10 × s +10 subframes in the PF; when the PO identifier is 1, the information of the PO may be the 10 th × s +1 th subframe in the PF; when PO is identified as 2, the information of PO may be the 10 th × s +5 th subframe in PF; when PO is identified as 3, the information of PO may be the 10 th × s +6 th subframe in PF.

Step S605: the UE determines the first number as a second number of frames contained by the PF.

It should be noted that, in this embodiment of the present application, an implementation manner in which the UE obtains the second quantity is the same as an implementation manner in which the base station obtains the second quantity, and then step S606 may specifically refer to the description of step S602, which is not described again in this embodiment of the present application.

Step S606: and the UE obtains the information of the PF according to the second quantity.

Before the UE receives the paging message, it needs to acquire information of the PO, and then receives the paging message at the PO indicated by the information of the PO. It should be noted that, in the embodiment of the present application, an implementation manner of the UE acquiring the information of the PF is the same as an implementation manner of the base station acquiring the information of the PF, and then step S607 may specifically refer to the description of step S202, which is not described again in the embodiment of the present application.

Step S607: and the UE obtains the information of the PO in the PF indicated by the information of the PF according to the first number.

It should be noted that, in the embodiment of the present application, an implementation manner of acquiring PO information by the UE is the same as an implementation manner of acquiring PO information by the base station, and step S608 may specifically refer to the description of step S604, which is not described again in the embodiment of the present application.

It should be noted that the embodiment of the present application does not limit the execution sequence of steps S605-S607 in fig. 6, and the UE may execute steps S605-S607 after receiving the first number of subframes included in the PO from the base station, for example, steps S605-S607 may be executed before or after step S602, before or after step S603, before or after step S604, or before or after step S608.

Step S608: the base station transmits a paging message to the UE at the PO indicated by the PO information.

After obtaining the information of the PO, the base station may send a paging message to the UE at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the tenth subframe and the twentieth subframe in the PF, the base station may send a paging message to the UE in the tenth subframe and the twentieth subframe in the DRX cycle.

In one design, after obtaining the information of the PO, the UE may receive the paging message at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the tenth subframe and the twentieth subframe in the PF, the UE may receive the paging message in the tenth subframe and the twentieth subframe in the DRX cycle.

In the method illustrated in fig. 6, the base station sends the first number of subframes included in the PO to the UE through a high layer signaling or a broadcast message, the base station determines the first number as the second number of frames included in the PF, the base station obtains information of the PO according to the first number and the second number, and sends a paging message to the UE at the PO indicated by the information of the PO, so that the UE can determine the first number as the second number of frames included in the PF, obtain information of the PO according to the first number and the second number, and receive the paging message at the PO indicated by the information of the PO, which can facilitate the second device to accurately identify the location of the PO.

Referring to fig. 7 based on the schematic architecture diagram of the communication system shown in fig. 1, fig. 7 is a communication method provided in the embodiment of the present application, which includes, but is not limited to, the following steps:

step S701: the base station transmits the first number of slots included in the PO to the UE through higher layer signaling or a broadcast message.

Wherein the first number is base station independently configured.

Step S702: the base station determines a third number of time slots contained in each subframe configured in advance.

In the LTE system, one subframe may include 2 slots; in NR, one subframe may include 2 slots, 4 slots, 6 slots, or 8 slots. Based on this, the base station may determine a third number of slots included in each subframe configured in advance.

Step S703: and the base station divides the first quantity by the third quantity and rounds the obtained quotient upwards to obtain a second quantity.

Specifically, in the embodiment of the present application, the POs are discontinuously distributed in the PF, and a configuration manner of the PO in each frame included in the PF is the same as a configuration manner of the PO in the LTE system. Wherein, the PO includes one subframe in the LTE system, the base station may determine that the number of slots included in each frame included in the PO in the PF is less than or equal to the third number. Based on this, the base station may divide the first number by the third number and round the resulting quotient up to obtain the second number. Illustratively, the first number of slots included in the PO is 10, and each pre-configured subframe includes 4 slots, the base station may determine that

I.e. the PF contains 3 frames.

Step S704: and the base station obtains the information of the PF according to the second quantity.

It should be noted that step S704 may specifically refer to the description of step S202, and the embodiments of the present application are not described again.

Step S705: the base station obtains information of the POs in the PF indicated by the information of the PF according to the first number.

Specifically, the base station may configure the POs in a non-continuous and non-uniformly distributed manner. The PO may be located in the PF at the 10 × ks +1 time slot, the 10 × ks +5 time slots, the 10 × ks +6 time slots, or the 10 × ks +10 time slots. Where s is 0, 1, 2 … m-1, m is the second number and k is the third number of slots contained in each subframe. Taking the schematic structure of the PO shown in fig. 8G as an example, if m is 1, k is 2, and n is 2, the information of the PO includes the timeslot number of the timeslot included in the PO, where the timeslot number is 0 and 10, the base station may determine that the PO is located in the first timeslot and the eleventh timeslot in the PF. If the slot number is 4, 14, the base station may determine that the PO is located in the fifth and fifteenth slots of the PF. If the slot number is 5, 15, the base station may determine that the PO is located in the sixth slot or the sixteenth slot in the PF. If the slot number is 9, 19, the base station may determine that the PO is located in the tenth slot or the twentieth slot in the PF. It should be noted that the information of the PO includes, but is not limited to, the slot number of the slot included in the PO, and may also be the slot number of the starting slot and the slot number of the ending slot included in the PO, and so on. It should be noted that, in the embodiment of the present application, the first number of timeslots included in the PO may be one, or may be multiple, and is not specifically limited by the embodiment of the present application.

In one design, when the calculated PF includes one PO, the first device may obtain a PO identification of the second device, and when the PO identification of the second device is the first identification, the first device may determine that the PO is located at 10 × ks +10 time slots in the calculated PF. Where k is the third number of slots contained in each subframe.

In one design, when the calculated PF includes two POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located at 10 × ks +5 time slots in the calculated PF; when the PO identity of the second device is the second identity, the first device may determine that the PO is located in the 10 × k × s +10 time slots of the calculated PF. Where k is the third number of slots contained in each subframe.

In one design, when the calculated PF includes four POs, the first device may obtain a PO identifier of the second device, and when the PO identifier of the second device is the first identifier, the first device may determine that the PO is located at 10 × ks +1 time slot in the calculated PF; when the PO identifier of the second device is the second identifier, the first device may determine that the PO is located in the 10 × k × s +5 th time slot in the calculated PF; when the PO identifier of the second device is the third identifier, the first device may determine that the PO is located in the 10 × k × s +6 th time slot in the calculated PF; when the PO identity of the second device is the fourth identity, the first device may determine that the PO is located in the 10 × k × s +10 time slots of the calculated PF. Where k is the third number of slots contained in each subframe.

i_s＝floor(UE_ID/N)mod Ns

For example, the corresponding relationship between the PO id and the PO information can be as shown in table six:

watch six

When the PF includes a PO and the PO is identified as 0, the information of the PO may include a duration, for example, 10 × k × s +10 time slots in the PF. When the PF contains two POs, and the PO is identified as 0, the information of the PO may include a duration, for example, 10 × k × s +5 time slots in the PF; when PO is identified as 1, the information of PO may be the 10 × ks +10 time slots in PF. When the PF contains four POs, and the PO is identified as 0, the information of the POs may include a duration, for example, 10 × k × s +1 time slot in the PF; when PO is identified as 1, the information of PO may be the 10 × ks +5 time slots in PF; when PO is identified as 2, the information of PO may be the 10 × ks +6 time slots in PF; when PO is identified as 3, the information of PO may be the 10 × ks +10 time slots in PF.

It should be noted that, the correspondence between the PO identifier and the PO information in the embodiment of the present application includes, but is not limited to, the above manner, for example, when the PF includes four POs and the PO identifier is 0, the PO information may include a duration, for example, 10 × ks +10 time slots in the PF; when PO is identified as 1, the information of PO may be the 10 × ks +1 time slot in PF; when PO is identified as 2, the information of PO may be the 10 × ks +5 time slots in PF; when PO is identified as 3, the information of PO may be the 10 × k × s +6 time slots in PF.

Step S706: the UE determines a third number of slots included in each of the pre-configured subframes.

Step S707: and the UE divides the first quantity by the third quantity and rounds the obtained quotient upwards to obtain a second quantity.

It should be noted that, in this embodiment of the present application, an implementation manner in which the UE obtains the second quantity is the same as an implementation manner in which the base station obtains the second quantity, and then step S708 may specifically refer to the description of step S703, which is not described again in this embodiment of the present application.

Step S708: and the UE obtains the information of the PF according to the second quantity.

Before the UE receives the paging message, it needs to acquire information of the PO, and then receives the paging message at the PO indicated by the information of the PO. It should be noted that, in the embodiment of the present application, an implementation manner of the UE acquiring the information of the PF is the same as an implementation manner of the base station acquiring the information of the PF, and then step S709 may specifically refer to the description of step S202, which is not described again in the embodiment of the present application.

Step S709: and the UE obtains the information of the PO in the PF indicated by the information of the PF according to the first number.

It should be noted that, in the embodiment of the present application, an implementation manner of acquiring PO information by the UE is the same as an implementation manner of acquiring PO information by the base station, and reference may be specifically made to the description of step S705 in step S710, which is not described again in the embodiment of the present application.

It should be noted that the embodiment of the present application does not limit the execution order of steps S706-S709 in fig. 7, and the UE may execute steps S706-S709 after receiving the first number of timeslots included in the PO from the base station, for example, steps S706-S709 may be executed before or after any step of steps S702-S705, and may also be executed before or after step S710.

Step S710: the base station transmits a paging message to the UE at the PO indicated by the PO information.

After obtaining the information of the PO, the base station may send a paging message to the UE at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the tenth slot and the twentieth slot in the PF, the base station may transmit a paging message to the UE in the tenth slot and the twentieth slot in the DRX cycle.

In one design, after obtaining the information of the PO, the UE may receive the paging message at the PO indicated by the information of the PO. For example, PF is the first frame and the second frame in the DRX cycle, and PO information is the tenth slot and the twentieth slot in the PF, the UE may receive the paging message in the tenth slot and the twentieth slot in the DRX cycle.

In the method illustrated in fig. 7, the base station sends the first number of timeslots included in the PO to the UE through a high layer signaling or a broadcast message, the base station obtains the second number according to the first number, obtains information of the PO according to the first number and the second number, and sends a paging message to the UE at the PO indicated by the information of the PO, so that the UE can obtain the second number according to the first number, obtain information of the PO according to the first number and the second number, and receive the paging message at the PO indicated by the information of the PO, which can facilitate the second device to accurately identify the location of the PO.
