Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: global system for mobile communications (GSM) systems, code Division Multiple Access (CDMA) systems, wideband Code Division Multiple Access (WCDMA) systems, general Packet Radio Service (GPRS), long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD), universal mobile telecommunications system (universal mobile telecommunications system, UMTS), worldwide Interoperability for Microwave Access (WiMAX) communication systems, future fifth generation (5 g) or new radio NR systems, etc.

By way of example and not limitation, the technical solution of the embodiment of the present application may be applied to an internet of things (IoT) system, a Machine Type Communication (MTC) system, or a machine to machine (M2M) system.

The IoT is an important component of future information technology development, and is mainly technically characterized in that articles are connected with a network through a communication technology, so that an intelligent network with man-machine interconnection and object interconnection is realized.

In the embodiment of the present application, the IOT technology may achieve massive connection, deep coverage, and power saving for the terminal through, for example, a Narrowband (NB) technology. For example, the NB includes only one Resource Block (RB), i.e., the bandwidth of the NB is only 180kHz. The communication method according to the embodiment of the application can effectively solve the problem of congestion of the IOT technology mass terminals when the mass terminals access the network through the NB.

The narrow definition of MTC is machine-to-machine communication, and the broad definition is networked applications and services with machine terminal intelligent interaction as the core. The MTC is an informatization solution scheme provided for a client by taking various communication modes as access means based on an intelligent machine terminal, and is used for meeting informatization requirements of the client on monitoring, command scheduling, data acquisition, measurement and the like.

IoT and MTC may be applied to industry applications, home applications, personal applications, and the like. Industrial applications such as traffic monitoring, alarm systems, rescue at sea, vending machines, driving payments, etc. Household applications such as automatic meter reading, temperature control, etc. Personal applications such as life detection, remote diagnostics, etc.

IoT and MTC are different from conventional LTE communication, which do not pursue data transmission rate, multiple frequency bands, multiple antennas, full duplex transmission, but pursue longer battery time of a terminal device, and lower cost of the terminal device, i.e. require the terminal to be able to achieve low power consumption (low cost)), and in addition, considering application scenarios of IoT and MTC terminals, such as water meters, electric meters, etc., the signal coverage strength of the terminal cannot meet the signal reception requirement, so the MTC is enhanced, so that the base station and the terminal can support extended coverage (coverage enhancement), and at present, the main method for achieving extended coverage is to repeatedly send uplink or downlink signals for multiple times, and achieve the purpose of improving the success rate of data reception by multiple times of reception and combination. In addition, in the application scenario of MTC or IoT, data transmission is characterized by small data volume and uncertain data arrival time. For example, the network side calls the terminal to report data, or the network side issues a control command to the terminal. In the prior art, in order to transmit data, a wireless connection between a base station and a terminal needs to be established, and establishing the wireless connection needs a certain signaling overhead, if only to transmit smaller data, a connection establishment procedure in the prior art is used, so that the utilization efficiency of wireless resources is reduced, a large amount of resources are used for the connection establishment procedure, and a small amount of resources are used for data transmission.

According to the scheme provided by the application, the power consumption of the terminal equipment can be effectively reduced, so that the requirement for reducing the power consumption of the terminal equipment in an MTC or IoT application scene can be met.

In addition, multiple cells can simultaneously work at the same frequency on a carrier in an LTE system or a 5G system, and under some special scenes, the concepts of the carrier and the cells can also be considered to be equivalent.

Access network device 102 may communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it is understood that access network device 102 may communicate with any number of terminal devices similar to terminal device 116 or terminal device 122.

End devices

116 and 122 may be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system 100.

As shown in fig. 1, terminal device 116 is in communication with

antennas

112 and 114, where

antennas

112 and 114 transmit information to terminal device 116 over a forward link (also called a downlink) 118 and receive information from terminal device 116 over a reverse link (also called an uplink) 120. In addition, terminal device 122 is in communication with

antennas

104 and 106, where

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

In a Frequency Division Duplex (FDD) system, forward link 118 may utilize a different frequency band than reverse link 120, and forward link 124 may employ a different frequency band than reverse link 126, for example.

As another example, in Time Division Duplex (TDD) systems and full duplex (full duplex) systems, forward link 118 and reverse link 120 may utilize a common frequency band and forward link 124 and reverse link 126 may utilize a common frequency band.

Each antenna (or group of antennas consisting of multiple antennas) and/or area designed for communication is referred to as a sector of the access network device 102. For example, antenna groups may be designed to communicate to terminal devices in a sector of the areas covered by access network device 102. The access network device may transmit signals to all terminal devices in its corresponding sector through single-antenna or multi-antenna transmit diversity. During communication by access network device 102 over

forward links

118 and 124 with

terminal devices

116 and 122, respectively, the transmitting antennas of access network device 102 may also utilize beamforming to improve signal-to-noise ratio of

forward links

118 and 124. Furthermore, mobile devices in neighboring cells may experience less interference when access network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area than if the access network device transmitted signals to all of its terminal devices through single or multiple antenna transmit diversity.

At a given time, access network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

Moreover, the communication system 100 may be a PLMN network, a device-to-device (D2D) network, a machine-to-machine (M2M) network, an IoT network, or other networks, and fig. 1 is a simplified schematic diagram for example only, and other access network devices may be included in the network, which is not shown in fig. 1.

In the embodiment of the present application, data or information may be carried by time-frequency resources, where the time-frequency resources may include resources in a time domain and resources in a frequency domain. In the time domain, the time-frequency resource may include one or more time units.

One time unit may be one symbol, or one Mini-slot (Mini-slot), or one slot (slot), or one subframe (subframe), where the duration of one subframe in the time domain may be 1 millisecond (ms), one slot may be composed of 7 or 14 symbols, and one Mini-slot may include at least one symbol (e.g., 2 symbols or 4 symbols or 7 symbols, or any number of symbols less than or equal to 14 symbols).

The scheme provided by the application can be applied to the paging process of the terminal equipment.

In mobile communication, it is possible to implement connection between a terminal device indicating an idle state (idle) and a network side through paging, or to instruct the terminal device indicating the idle state to perform other processing (e.g., system message for updating a cell) according to an instruction of the network side.

Specifically, the terminal device may include two states, i.e., an idle state and a connected state (connected).

A network device (e.g., a core network device or an access network device) may page for idle and connected terminal devices.

The paging process may be triggered by the core network device, that is, the terminal device is notified to receive the paging request.

Alternatively, the paging procedure may be triggered by the access network device to notify the terminal device to update system information, or notify the terminal device to receive an Earthquake and Tsunami Warning System (ETWS) message or a Commercial Mobile Alert System (CMAS) message, etc.

If the paging message received by the terminal device carries a user identity (UE ID) list, the terminal device needs to compare the UE ID in the UE ID list with the UE ID of the terminal device itself to determine whether the paging message calls the terminal device, that is, if the UE ID of the terminal device itself is in the UE ID list, the paging message is identified to call the terminal device; and if the UE ID of the terminal equipment is not in the UE ID list, identifying that the paging message does not call the terminal equipment.

In addition, a paging identification (paging ID) may be included in the paging message.

Wherein, if the paging ID is, for example, a system architecture evolution temporary mobile subscriber identity (S-TMSI), it indicates that the paging is a normal service call.

Or, if the paging ID is, for example, an International Mobile Subscriber Identity (IMSI), it identifies that the paging is an abnormal call for error recovery on the network side, and, for example, in this case, the terminal device may perform an attach (attach) procedure again.

By way of example and not limitation, the channel carrying the paging message may be a Paging Control Channel (PCCH), where the PCCH is a logical channel. The data block of the PCCH may be carried by a Paging Channel (PCH), which is a transport channel. The PCH is carried on a Physical Downlink Shared Channel (PDSCH). Because the PDSCH may also carry downlink data, before receiving a paging message, the terminal device may monitor a Physical Downlink Control Channel (PDCCH), and determine whether a paging cycle (specifically, a PDSCH of the paging cycle) includes a paging message sent to the terminal device according to whether the PDCCH carries a paging mobile network temporary identifier (P-RNTI) of the terminal device, that is, if the PDCCH carries the P-RNTI, it indicates that the paging cycle includes the paging message sent to the terminal device; and if the PDCCH does not carry the P-RNTI, the paging cycle does not comprise the paging message sent to the terminal equipment.

In this application, in order to reduce power consumption of the terminal device, a Discontinuous Reception (DRX) technique may be used, that is, in the DRX mode, the terminal device may periodically enter a sleep mode in some time periods, and does not monitor a subframe carrying a Physical Downlink Control Channel (PDCCH), and when monitoring is required, wakes up from the sleep mode, so that the UE can achieve the purpose of saving power.

In this case, the terminal device may monitor the PDCCH scrambled by the P-RNTI only in a Paging Occasion (PO) on a corresponding paging radio frame (PF) within one DRX cycle, and further determine whether the PDSCH indicated by the PDCCH carries a paging message. For example, if the P-RNTI is carried in the PDCCH, the data on the PDSCH is received according to the parameter of the PDSCH indicated on the PDCCH, and then the paging message is obtained; if the terminal equipment does not resolve the P-RNTI on the PDCCH, the PDSCH does not need to be received, and the terminal equipment can enter the sleep mode according to the DRX period.

That is, through the above mechanism, in one DRX cycle, the terminal device may receive the PDCCH only at the time position where the PO occurs, and then receive the PDCCH according to whether the PDCCH carries the P-RNTI, so as to achieve the purpose of reducing the power consumption of the terminal device.

In the present application, the terminal device and the network device (e.g., access network device or core network device) may determine the PO of the terminal device based on the following method.

For example, the terminal device may first determine a frame number, i.e., PF, of a radio frame carried by a PDCCH to be monitored. The PO on the PF is then determined.

By way of example and not limitation, PF may be determined in the present application based on the following equation 1:

SFN mod T = (T/S) × (K mod S) formula 1

That is, the radio frames indicated by the SFN satisfying equation 1 may be all used as the PF.

Where SFN is system frame number, as an example and not by way of limitation, SFN may take a value range of [0, 1023].

T represents a DRX parameter, which may be broadcast by the network device in a system message, e.g., SIB2, by way of example and not limitation, and may include, but is not limited to, 32, 64, 128, 256, or the like, where the unit of T may be a radio frame.

And, the value of S may be the minimum value of T and nB, nB may be a parameter broadcasted by the network device in a system message, for example, SIB2, and the value of nB may include, but is not limited to, 4T, 2T, T, T/2, T/4, T/8, T/16, or T/32, where the unit of S and nB may be a radio frame.

And K is the equipment identifier of the terminal equipment, or K is a numerical value corresponding to the equipment identifier of the terminal equipment.

For example, K = Q mod 1024, where Q may be the IMSI of the terminal device.

In this application, the PO may be a subframe number of the PDCCH that the terminal device needs to monitor on the PF.

That is, the terminal device and the network device may calculate the position D of the PO of the terminal device on the PF, and then may determine the PO according to the corresponding relationship between the D and the PO.

By way of example, and not limitation, D may be determined in the present application based on equation 2 below.

D = floor (K/S) mod nS equation 2

Wherein nS may be the maximum of 1 and nB/T. For example, the value of nS may include, but is not limited to, 1, 2, or 4, as explained above for nB in equation 1.

That is, in the present application, the value range of D may include, but is not limited to, 0, 1, 2, or 3.

Table 1 below shows an example of the correspondence relationship between D and PO in the present application.

TABLE 1

nS	Value of PO when D =0	Value of PO when D =1	Value of PO when D =2	Value of PO when D =4
					1	0	Unusable (N/A)	N/A	N/A
2	0	5	N/A	N/A
					4	0	1	5	6

In order to reduce the power consumption of the terminal device, a wake-up mechanism may be introduced, i.e. the terminal device may detect a wake-up signal (WUS) before the PO determined as described above, detect a paging message at the PO if a WUS is detected, and sleep at the PO if a WUS is not detected.

In this case, if there is a terminal apparatus (denoted as terminal apparatus # b) within the PO which does not need to be paged, the terminal apparatus # b wakes up within the PO due to the detection of the WUS, resulting in an increase in power consumption of the terminal apparatus # b

In this regard, in the present application, a plurality of terminal devices in the same PO may be divided into a plurality of (e.g., U) terminal device groups, and, as shown in fig. 2, each terminal device group may correspond to one WUS, or each terminal device group may correspond to one time-frequency resource carrying the WUS, where a mapping relationship between each terminal device group and each WUS may be specified by a communication system or a communication protocol, or a mapping relationship between each terminal device group and each WUS may be configured by a network device.

Therefore, one terminal device can determine the terminal device group to which the terminal device belongs and detect the WUS on the time-frequency resource corresponding to the terminal device group.

The process of determining the terminal device group will be described in detail below with reference to fig. 2 and 3.

Fig. 2 shows a schematic flow of an example of a method 200 for wake-up signal transmission between a network device # a (e.g., an access network device) and a terminal device # a.

As shown in fig. 2, at S210, the terminal apparatus # a may acquire paging feature information of the terminal apparatus # a, which is hereinafter referred to for ease of understanding as: paging feature information # a.

Wherein the paging feature information # a may be used to determine or indicate the paging feature of the terminal device # a.

By way of example and not limitation, the paging characteristic information may include, but is not limited to, at least one of the following information, or the paging characteristic may include, but is not limited to, at least one of the following characteristics.

A. Paging frequency

In particular, the paging frequency may be used to measure how often the terminal device is paged.

For example, the paging frequency may be characterized in terms of the number of times the terminal device is paged within a specified time (e.g., a PO or multiple consecutive POs).

B. Probability of paging

Specifically, the paging probability may be used to measure the likelihood that a terminal device is paged within a specified time (e.g., a PO or multiple consecutive POs).

C. Service arrival rate

For example, the traffic arrival rate may be understood as the frequency of traffic arrival, and specifically, the frequency of traffic arrival may be characterized according to the number of times that the terminal device receives downlink data at a specified time (e.g., a PO or a plurality of consecutive POs).

As another example, the service arrival rate may be understood as a probability of service arrival, and specifically, the probability of service arrival may be used to measure a probability that the terminal device receives downlink data at a specified time (e.g., one PO or multiple continuous POs).

As an example and not by way of limitation, in the present application, the paging feature information # a may be determined according to a function of the terminal device # a, for example, in the present application, the terminal device # a may be a terminal device in MTC or IoT, for example, a smart water meter or a smart electricity meter, and because the function of the terminal device is simple and the service access time is fixed, a manufacturer or an operator may determine the paging feature information according to experiment or historical data, and may issue the paging feature information to the terminal device when the terminal device leaves a factory or enters a network.

It should be understood that the above-listed method and procedure for the terminal apparatus # a to determine the paging feature information # a are only exemplary, the present application is not limited thereto, and other methods and procedures for the terminal apparatus # a to determine the paging feature information # a fall within the protection scope of the present application.

In S250, the terminal apparatus # a can specify a terminal apparatus group to which the terminal apparatus belongs from among a plurality of terminal apparatus groups based on the paging feature information # a, and this terminal apparatus group # a is denoted as terminal apparatus group # a.

By way of example and not limitation, terminal device group # a may be determined in at least one of the following ways in the present application.

Mode 1

In this application, each of the plurality of terminal device groups may correspond to one index value.

The terminal apparatus # a may acquire a function # a, which may be used to indicate a functional relationship between a numerical value and an index value. That is, the value may be an argument of the function # a, and the index value may be a dependent variable of the function # a.

Thus, the terminal apparatus # a may bring a numerical value (for example, a probability value or a percentage) corresponding to the paging feature information # a as an argument into the function # a, and calculate a result (denoted as an index # a) as an index of the terminal apparatus group # a, or the terminal apparatus # a may take a terminal apparatus group corresponding to the index # a as the terminal apparatus group # a.

By way of example and not limitation, the function # a may include the following functions:

Y＝F mod V

where Y denotes an index of the terminal device group # a, V is a preset constant, and F is a value determined according to the paging feature information # a, and for example, when the paging feature information # a is a probability (e.g., a traffic arrival rate or a paging probability), F may be a probability value indicated by the paging feature information # a.

By way of example and not limitation, the value of V may be predefined by the communication system or communication protocol, or the value of V may be determined by the network device # a and issued to the terminal device # a.

Also, the rule (or expression) of the function # a may be previously specified by the communication system or the communication protocol, or the rule of the function # a may be determined by the network device # a and issued to the terminal device # a.

Mode 2

In the present application, each of the plurality of terminal device groups may correspond to a range of values.

For example, the value ranges (or boundaries) of any two terminal device groups may be different. Alternatively, the value ranges of any two terminal device groups may have no overlapping portions.

Thus, the terminal apparatus # a can determine a value range (denoted as a value range # a) in which a value (for example, a frequency value or a probability value) corresponding to the paging feature information # a is located.

The terminal apparatus # a may determine the terminal apparatus group corresponding to the numerical range # a as the terminal apparatus group # a.

Also, the numerical range corresponding to each terminal device group may be predefined by the communication system or the communication protocol, or the numerical range corresponding to each terminal device group may be determined by the network device # a and issued to the terminal device # a.

That is, in the present application, different terminal devices may have different paging characteristics (e.g., traffic arrival rate, frequency paged or probability paged, etc.).

Also, in the present application. The paging features may be classified into R classes, which may correspond to R groups of terminal devices.

For example, when R =2, the 2 terminal device groups may include a terminal device group with a high value corresponding to the paging feature (for example, the traffic frequently arrives such that the traffic arrival rate is higher than a preset threshold), for example, the index of the terminal device group may be "0", and the 2 terminal device groups may include a terminal device group with a low value corresponding to the paging feature (for example, the traffic occasionally arrives such that the traffic arrival rate is lower than the preset threshold), for example, the index of the terminal device group may be "1".

For another example, when R =2, the 2 terminal device groups may include a terminal device group with a high value corresponding to the paging feature (for example, the terminal device is frequently paged so that the paging probability is higher than the preset threshold), for example, the index of the terminal device group may be "0", and the 2 terminal device groups may include a terminal device group with a low value corresponding to the paging feature (for example, the terminal device is occasionally paged so that the paging probability is lower than the preset threshold), for example, the index of the terminal device group may be "1".

The classification criteria and thresholds of the paging features may be specified by a protocol. Or the classification standard and the threshold of the paging feature may be agreed when the terminal device subscribes to an operator, or the classification standard and the threshold of the paging feature may be fixed when a chip of the terminal device leaves a factory.

In S270, the terminal device # a determines a WUS (denoted as WUS # a) corresponding to the terminal device group # a according to a preset corresponding relationship (denoted as mapping relationship # a), or, the terminal device # a determines a time-frequency resource (denoted as time-frequency resource # a) for carrying the WUS corresponding to the terminal device group # a according to the preset corresponding relationship. Also, the terminal apparatus # a may detect the WUS # a, or the terminal apparatus # a may detect whether the time-frequency resource # a carries the WUS. By way of example and not limitation, the mapping relationship # a may be prescribed by the communication system or the communication protocol, or the mapping relationship # a may be determined by the network device # a and issued to the terminal device # a.

Accordingly, the network device # a can also determine the terminal device group # a, and further, when there is a terminal device requiring paging in the terminal device group # a, WUS can be transmitted to the terminal devices in the terminal device group # a including the terminal device # a on the time-frequency resource # a.

By way of example and not limitation, in the present application, the network device may determine the terminal device group # a based on any one of the following manners.

Mode 3

Optionally, the network device # a may obtain the paging feature information # a, or a value corresponding to the paging feature information # a, and the network device # a may determine the terminal device group # a according to the feature information # a or the value corresponding to the paging feature information # a, where the determining process may be similar to the process of determining the terminal device group # a according to the feature information # a by the terminal device # a described in the above S250, and here, detailed description thereof is omitted to avoid redundant description.

Alternatively, at S210, the terminal apparatus # a may transmit the paging feature information # a, or a value corresponding to the paging feature information # a, to the network apparatus # a.

For example, the terminal apparatus # a may carry the paging feature information # a through a message such as a registration request or an attach request, or a value corresponding to the paging feature information # a during a registration or attach (attach) process.

And, the message may carry the terminal device identifier of the terminal device # a, for example, IMSI.

Mode 4

Alternatively, at S260, the terminal apparatus # a may transmit the index # a to the network apparatus # a.

For example, the terminal apparatus # a may carry the index # a in a registration or attach procedure through a message such as a registration request or an attach request.

Thus, the network device # a can determine the terminal device group corresponding to the index # a as the terminal device group # a.

Mode 5

For example, when the terminal apparatus # a needs to be paged, the core network apparatus may provide the paging feature information # a or the index # a to the network apparatus # a (e.g., access network apparatus), and thus, the network apparatus # a may determine the terminal apparatus group # a according to the paging feature information # a or the index # a.

It should be understood that the above-listed method and procedure for the network device # a to acquire the paging feature information # a are only exemplary, and the present application is not limited thereto, for example, the network device # a may acquire the paging feature information # a from the manufacturer of the terminal device # a or a network operator.

Fig. 3 shows a schematic flow of an example of a method 200 for wake-up signaling between a network device # B (e.g., an access network device) and a terminal device # B.

As shown in fig. 3, at S310, the terminal apparatus # B may acquire at least two kinds of packet information.

By way of example and not limitation, in the present application, the grouping information may include, but is not limited to, at least two of the following information:

1. paging feature information of the terminal apparatus # B

The function and specific example of the paging feature information are similar to the paging feature information described in the method 200, and here, detailed description thereof is omitted to avoid redundancy.

2. Device identification information of the terminal device # B

Wherein the device identification information of the terminal device # B can be used to indicate the terminal device # B,

for example, the device identification information may be configured in the terminal device when the terminal device is shipped from the factory.

Alternatively, the device identification information may be assigned to the terminal device by an operator when the user signs up.

Alternatively, the device identification information may be assigned to the terminal device by the network device when the terminal device accesses the network.

As an example and not by way of limitation, in the present application, at least one of the following information may be used as the device identification information:

an Internet Protocol (IP) address, an IP port, a Media Access Control (MAC) address, a mobile phone number, an International Mobile Subscriber Identity (IMSI), an International Mobile Equipment Identity (IMEI), a Radio Network Temporary Identity (RNTI), and the like.

Alternatively, the device identification information (denoted as UE ID) may be determined from the above information.

For example, UE ID = IMSI mod 1024 when P-RNTI is monitored on PDCCH. .

UE ID = IMSI mod 4096 when P-RNTI is monitored on NPDCCH.

UE ID = IMSI mod 16384 when P-RNTI is monitored on MPDCCH or NPDCCH, paging is supported by the terminal device on a non-anchor carrier (non-anchor carrier), and the system information provides a paging configuration on the non-anchor carrier (non-anchor carrier).

For another example, UE _ ID = IMSI mode D, D being a preset integer.

3. Coverage information of the terminal device # B

The coverage information may be used to indicate a coverage of the terminal device, and specifically, the coverage may be understood as a range where a signal transmitted by the terminal device can reach, or the coverage may be understood as a range where the terminal device can receive a signal, that is, the terminal device can communicate with a communication device, for example, an access network device, in its coverage.

4. Time interval information of the terminal apparatus # B

The time interval information may be used to indicate a time interval between a transmission time of the WUS corresponding to the terminal device (or a time corresponding to a time-frequency resource carried by the WUS of the terminal device) and a PO of the terminal device.

5. DRX cycle information of the terminal apparatus # B

Wherein the DRX cycle information may be used to indicate a cycle of DRX or eDRX of the terminal device.

In S350, the terminal apparatus # B may determine a terminal apparatus group to which the terminal apparatus belongs from among a plurality of terminal apparatus groups based on the at least two types of grouping information, and may refer to the terminal apparatus group # B.

Hereinafter, for convenience of understanding and explanation, a process of determining a terminal device group based on the group information #1 and the group information #2 of the at least two types of group information will be described as an example, and the group information #1 of the terminal device # B will be referred to as group information #1_B, the group information #2 of the terminal device # B will be referred to as group information # 2_B.

By way of example and not limitation, at least one of the following ways may be employed in the present application to determine terminal device group # B, and in particular, to determine the index of terminal device group # B.

Mode A

Terminal apparatus # B can determine index #1 from packet information # 1_B.

Assuming that the value of index #1 is m and the value corresponding to packet information #1_B is K, this m can be expressed as a function of K (denoted as function # 1).

That is, the function # B may be used to indicate a functional relationship between a numerical value and an index value. That is, the value may be an argument of the function # B, and the index value may be a dependent variable of the function #1.

Thus, the terminal apparatus # B can bring the numerical value corresponding to the packet information #1_B as an argument into the function # a, and calculate the result as the index #1.

By way of example and not limitation, the function #1 may include the following functions:

m＝K mod C

where m denotes that the index #1,C is a preset constant, and K is a numerical value determined according to the grouping information #1_B, for example, when the grouping information #1_B is device identification information, the K may be a device identification, for example, IMSI, of the terminal device # B.

By way of example and not limitation, the value of C may be predefined by the communication system or communication protocol, or the value of C may be determined by the network device # B and issued to the terminal device # B.

Also, the rule (or expression) of the function #1 may be prescribed by the communication system or the communication protocol, or the rule of the function #1 may be determined by the network device # B and issued to the terminal device # B.

Also, terminal apparatus # B can determine index #2 from packet information # 2_B.

If the value of index #2 is n and the value corresponding to packet information #2_B is H, then m can be expressed as a function of H (denoted as function # 2).

That is, the function #2 may be used to indicate a functional relationship between a numerical value and an index value. That is, the value may be an argument of the function #2, and the index value may be a dependent variable of the function #2.

Thus, the terminal apparatus # B can bring the numerical value corresponding to this packet information #2_B as an argument to the function #2 and calculate the result as the index #2.

By way of example and not limitation, this function #2 may include the following functions:

n＝H mod D

where n denotes that the index #2,D is a preset constant, and H is a value determined according to the packet information #2_B, for example, when the packet information #2_B is paging feature information (e.g., paging frequency information, paging probability information, or service arrival rate information), H may be a frequency value or a probability value corresponding to the paging feature information.

By way of example and not limitation, the value of D may be predefined by the communication system or communication protocol, or the value of D may be determined by the network device # B and issued to the terminal device # B.

Also, the rule (or expression) of the function #2 may be prescribed by the communication system or the communication protocol, or the rule of the function #2 may be determined by the network device # B and issued to the terminal device # B.

By way of example and not limitation, for example, the following condition can be satisfied by configuring the rule of function #1 and the constant C: m is more than or equal to 0 and less than or equal to M-1.

For example, the rule of function #2 and constant D may be configured such that the value range of n satisfies the following condition: 0. n is not less than N and not more than N-1.

Specifically, in the present application, the number L of the plurality of terminal device groups (i.e., terminal devices within the same PO as terminal device # B) may be P + M + N, or L may be M + N.

Where M can be understood as the total number of terminal device groups in the communication system corresponding to the grouping information #1.

That is, the group of M terminal devices can be divided according to the values of all possible grouping information #1 of the terminal devices in the communication system.

By way of example and not limitation, M may be an integer greater than or equal to 1.

And, the value of M may be specified by a communication system or a communication protocol.

Alternatively, the value of M may be configurable by the network device.

In addition, N can be understood as the total number of terminal device groups corresponding to the grouping information #2 in the communication system.

That is, the group of N terminal devices can be divided according to the values of all possible grouping information #2 of the terminal devices in the communication system.

By way of example and not limitation, N may be an integer greater than or equal to 1.

And, the value of N may be specified by a communication system or a communication protocol.

Alternatively, the value of N may be configurable by the network device.

P may represent the number of reserved terminal device groups in the plurality of terminal device groups.

By way of example and not limitation, the reserved group of terminal devices may include all terminal devices within a defined PO, where the defined PO may be a PO that all terminal devices within the PO need to wake up.

By way of example and not limitation, P may be an integer greater than or equal to 0.

For example, the value of P may be 0, that is, the reserved terminal device group may not be included in the plurality of terminal device groups, in this case, the number L of the plurality of terminal device groups may also be represented as M + N.

Assuming that the value of the index of the terminal device group # B is Y, this Y can be expressed as a function of n and m (note, function # 3).

That is, the function #3 may be used to indicate a functional relationship between a numerical value and an index value. That is, the value may be an argument of the function #3, and the index value may be a dependent variable of the function # 3.

Thus, the terminal apparatus # B can bring the value corresponding to n and the value corresponding to m as arguments into the function #3, and calculate the result Y as an index of the terminal apparatus group # B.

By way of example and not limitation, the function #3 may include any of the following functions:

Mode B

In the present application, the weighting value of the index corresponding to each piece of packet information #2 may be determined according to the possible values of each piece of packet information #2.

For example, assume that 8 terminal devices exist in the same PO, and 3 indexes can be determined according to possible values of the grouping information #2 of the 8 terminal devices, for example, 2 indexes determined by the terminal devices according to the grouping information #2 are set as an index # a, 4 indexes determined by the terminal devices according to the grouping information #2 are set as an index # b, and 2 indexes determined by the terminal devices according to the grouping information #2 are set as an index # c.

f (K) may represent a value of K, or a function of K, which is a numerical value determined according to the grouping information #1_B, for example, when the grouping information #1_B is device identification information, the K may be a device identification of the terminal device # B, for example, IMSI or UE ID.

By way of example, the function rule corresponding to f (K) may be specified by a communication system or a communication protocol, or the function rule corresponding to f (K) may be configured by a network device.

By way of example and not limitation, the rule (or expression) of the function #4 may be prescribed by the communication system or the communication protocol, or the rule of the function #4 may be determined by the network device # B and issued to the terminal device # B.

Mode C

In the present application, an index list corresponding to each piece of packet information #2 (or, an index determined based on the piece of packet information # 2) may be determined according to a possible value of each piece of packet information #2.

For example, it is assumed that there are 8 terminal devices in the same PO, and 3 indexes can be determined according to possible values of group information #2 of the 8 terminal devices, for example, it is assumed that there are 2 indexes determined by the terminal devices according to the group information #2 thereof as an index # a, there are 4 indexes determined by the terminal devices according to the group information #2 thereof as an index # b, and there are 2 indexes determined by the terminal devices according to the group information #2 thereof as an index # c. The index list of index # a may include 2 indexes, the index list of index # b may include 4 indexes, and the index list of index # c may include 2 indexes.

Also, the terminal apparatus # B can specify the index list (denoted as index list # a) corresponding to the index #2.

By way of example and not limitation, this P may represent a function of f (K) (denoted as function # 5).

By way of example and not limitation, this function #5 may include the following functions:

where f (K) may represent a value of K, or f (K) represents a function of K, where K is a numerical value determined according to the grouping information #1_B, for example, when the grouping information #1_B is device identification information, the K may be a device identification of the terminal device # B, for example, IMSI or UE ID.

By way of example and not limitation, the rule (or expression) of the function #5 may be prescribed by the communication system or communication protocol, or the rule of the function #5 may be determined by the network device # B and issued to the terminal device # B.

In S370, the terminal device # B determines a WUS (write, WUS # B) corresponding to the terminal device group # B according to a preset corresponding relationship (write, mapping # B), or, the terminal device # B determines a time-frequency resource (write, time-frequency resource # B) for carrying the WUS corresponding to the terminal device group # B according to the preset corresponding relationship. Also, the terminal apparatus # B may detect the WUS # B, or the terminal apparatus # B may detect whether the time-frequency resource # B carries the WUS. By way of example and not limitation, the mapping relationship # B may be prescribed by a communication system or a communication protocol, or the mapping relationship # B may be determined by the network device # B and issued to the terminal device # B.

Accordingly, the network device # B can also determine the terminal device group # B, and further, when there is a terminal device that needs to be paged in the terminal device group # B, WUS can be transmitted to the terminal devices in the terminal device group # B including the terminal device # B on the time-frequency resource # B.

For example, at S310, the terminal apparatus # B can transmit each packet information (for example, packet information #1_B and packet information # 2_B) to the network apparatus # B.

For example, the terminal device # B may carry each packet information through a message such as a registration request or an attach request, or a value corresponding to each packet information in a registration or attach (attach) process.

For another example, in S360, the terminal apparatus # B transmits to the network apparatus # B an index determined based on each piece of packet information, that is, an index of the terminal apparatus group # B.

For example, the terminal device # B may carry the index of the terminal device group # B through a message, such as a registration request or an attach request, during a registration or attach procedure.

For another example, when paging of the terminal apparatus # B is required, the core network apparatus may provide the network apparatus # B (e.g., access network apparatus) with the packet information of the terminal apparatus # B, and thus the network apparatus # B may determine the terminal apparatus group # B from the packet information of the terminal apparatus # B.

It should be understood that the above-listed method and procedure for the network device # B to acquire the packet information of the terminal device # B are only exemplary, and the present application is not limited thereto, for example, the network device # B may acquire the packet information of the terminal device # B from the manufacturer of the terminal device # B or a network operator.
