Description

Technical Field

[0002] In the related art, when a terminal is in a Radio Resource Control IDLE (RRC-IDLE) state or a Radio Resource Control inactive state (RRC-INACTIVE), it is necessary to periodically monitor paging messages, and after receiving a Paging message, it is necessary to enter a Radio Resource Control CONNECTED (RRC-CONNECTED) state for normal communication. The Paging message is carried in a physical downlink shared channel (PDSCH), and needs to be scheduled by downlink control information (DCI) scrambled by a paging radio network temporary identity (P-RNTI). For a terminal, its paging occasion (PO) occurs periodically, and multiple terminals may use the same set of periodic PO resources, that is, paging messages of multiple terminals may appear in one PO.

[0003] However, when there are multiple terminals corresponding to one PO, when the terminal receives the DCI indicating that there is paging information, it needs to fully demodulate the PDSCH to determine whether there is paging information for the terminal. There is a situation where the terminal finds that there is no paging information for the terminal after demodulating the PDSCH, which will waste the energy of the terminal and affect the battery life.

[0078] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0079] The paging method provided in the embodiment of the present disclosure can be applied to Figure 1 In the wireless communication system shown in FIG. Figure 1 As shown, the wireless communication system includes a terminal and a network device. The terminal is connected to the network device through wireless resources and performs data transmission and reception.

[0080] Understandably, Figure 1 The wireless communication system shown is only for schematic illustration. The wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices. Figure 1 The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0081] It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access / collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to the capacity, rate, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called new radio network (New Radio, NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as a network.

[0082] Furthermore, the network equipment involved in the present disclosure may also be referred to as a wireless access network device. The wireless access network device may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in ​​an NR system, or it may also be a component or part of a device constituting a base station. When it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited.

[0083] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a PDA, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0084] In the related technology, the terminal can be in RRC-IDLE state, RRC-INACTIVE state or RRC-CONNECTED state. The terminal in RRC-IDLE state or RRC-INACTIVE state needs to periodically monitor the paging message, and enter the RRC-CONNECTED state for normal communication after receiving the Paging message. The Paging message is carried in the PDSCH and needs to be scheduled by the DCI encrypted by the P-RNTI. For a terminal, its PO appears periodically, and multiple terminals may use the same set of periodic PO resources, that is, paging messages of multiple terminals may appear in one PO.

[0085] The process of the terminal monitoring the Paging message is as follows: the terminal monitors whether there is a DCI encrypted with P-RNTI in the PO. If a DCI encrypted with P-RNTI is detected in the PO, and the Short Messages Indicator information field in the DCI shows that the DCI schedules the PDSCH containing the paging message. The terminal receives and demodulates the PDSCH according to the instructions of the DCI. If no DCI encrypted with P-RNTI is detected, or there is such a DCI, but the Short Messages Indicator information field in the DCI shows that there is no paging message, the terminal does not need to receive and demodulate the PDSCH. The PDSCH contains a paging record table, which contains all the terminal identifiers (IDs) paged on the PO. The terminal ID used for paging in the NR system is generally 5G-S-TMSI, which is 48 bits in length. If the terminal finds its own ID in the paging record table, it means that the terminal has been paged and needs to switch to the RRC connected state for normal communication. If the paging record table does not contain its own ID, it means that the terminal has not been paged and can continue to remain in the RRC idle state or the RRC inactive state.

[0086] In the above paging process, it is common for multiple terminals to correspond to one PO. When there are multiple terminals corresponding to one PO, each terminal is not clear whether there are other terminals on the PO corresponding to this terminal. When the terminal receives the DCI indicating that there is paging information, it is not clear whether the paging information in the PDSCH is for this terminal. It is necessary to fully demodulate the PDSCH before determining whether there is its own paging information. Therefore, there is a situation where the terminal finds that there is no paging information for this terminal after demodulating the PDSCH. This situation will waste the energy of the terminal and affect the battery life.

[0087] In the NR system, DCI 1-0 can be used to schedule paging information. When DCI 1-0 is used to schedule paging information, some bits in the information field of DCI will be in a reserved state, where the bits in the reserved state can be understood as retaining these bits, but not for any purpose. For example: when the Short Messages Indicator information field in DCI 1-0 indicates "no short message, but there is paging information", the 8 bits of the Short Messages information field will be in a reserved state. On the licensed spectrum, the last information field in DCI 1-0 is 6 bits that are always in a reserved state, or on the unlicensed spectrum, the last information field in DCI 1-0 is 8 bits that are always in a reserved state. Regardless of whether there is a short message, bits 3-8 of the 8 bits in the Short Messages information field in the current protocol version are reserved.

[0088] In view of this, an embodiment of the present disclosure provides a paging message method, in which bits in the DCI that are at least partially in a reserved state are used to indicate whether there is a paging message for one or more terminal groups, so that the terminal can determine whether there is a paging message based on the received DCI, and then when the DCI indicates that there is no paging message, the paging message is not received and the paging message is not demodulated, thereby saving energy for the terminal.

[0089] Figure 2 is a flow chart of a paging method according to an exemplary embodiment. Figure 2 As shown, the paging method is used in a network device and includes the following steps.

[0090] In step S11, DCI is determined, where the DCI includes one or more bits, and each of the one or more bits indicates whether a paging message exists for a terminal group or not.

[0091] Among them, the embodiment of the present disclosure can determine at least part of the bits in the DCI that are in a reserved state as one or more bits indicating whether there is a paging message for the terminal group.

[0092] In step S12, DCI is sent.

[0093] In the embodiment of the present disclosure, a bit in the DCI is used to indicate whether a paging message exists for a terminal group, so that the terminal can determine whether a paging message exists based on the received DCI. When the DCI indicates that no paging message exists, the terminal does not receive the paging message or demodulate the paging message, thereby saving energy.

[0094] Figure 3is a flow chart of a paging method according to an exemplary embodiment. Figure 3 As shown, the paging method is used in a terminal and includes the following steps.

[0095] In step S21, DCI is acquired, where the DCI includes one or more bits, and each of the one or more bits indicates whether a paging message exists for a terminal group or not.

[0096] In step S22, the terminal group to which the terminal belongs is determined, and based on the terminal group to which the terminal belongs and the bit indicating the terminal group to which the terminal belongs, it is determined whether to receive a paging message or not.

[0097] In the disclosed embodiment, the terminal determines the terminal group to which the terminal belongs, and when it is determined that the bit corresponding to the terminal group to which the terminal belongs indicates that there is no paging message for the terminal group, it is determined that there is no need to receive and demodulate the PDSCH containing the paging message. When it is determined that the bit corresponding to the terminal group to which the terminal belongs indicates that there is a paging message for the terminal group, it is determined that there is a need to receive and demodulate the PDSCH containing the paging message.

[0098] It is understandable that, since the reserved bit indicates the terminal group, and the paging message may be for the paging message of other terminals in the same terminal group, there is a situation where the terminal determines that there is no paging message for the terminal after demodulating the PDSCH containing the paging message. However, compared with receiving and demodulating all PDSCH containing paging messages indicated by DCI, the power consumption of the terminal can still be reduced to a certain extent, achieving the effect of energy saving.

[0099] The paging method involved in the above embodiment will be described below in combination with practical applications.

[0100] In one implementation of the embodiment of the present disclosure, the DCI used to indicate whether a paging message exists in the terminal group may be a DCI used to schedule a paging message.

[0101] In the embodiment of the present disclosure, N bits in the reserved state in the DCI of the scheduled paging message can be used to indicate whether a paging message exists or not for the terminal group, wherein the value of N is a positive integer less than or equal to the number of bits in the reserved state.

[0102] In the embodiment of the present disclosure, there is a one-to-one correspondence between the N bits used to indicate whether there is a paging message for one or more terminal groups and the terminal groups, that is, each bit in the N bits corresponds to a terminal group.

[0103] The N bits involved in the embodiment of the present disclosure indicate N terminal groups. The number of terminal groups, or the number of reserved bits in the DCI for indicating whether there is a paging message, can be determined in the following manner:

[0104] In method 1, it is determined based on the reserved bits of the last information field of the DCI in the authorized spectrum. For example, on the authorized spectrum, if the number of reserved bits of the last information field of the DCI for scheduling paging messages is 6, then N=6 can be determined, and the 6 bits reserved in the last information field of DCI 1-0 are directly used.

[0105] In method 2, it is determined based on the reserved bits of the last information field of DCI in the unlicensed spectrum. For example, in the unlicensed spectrum, the number of reserved bits of the last information field of DCI for scheduling paging messages is 8, then N=8 can be determined, and the 8 bits reserved in the last information field of DCI 1-0 are directly used.

[0106] In mode 3, it is determined based on the reserved bits in the Short Messages information field in the DCI. For example, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but paging information", there are reserved bits in DCI 1-0, and N=8 is determined, and 8 bits of the Short Messages information field are used.

[0107] In mode 4, it is determined based on the reserved bits of the Short Messages information field in the DCI in the authorized spectrum and the reserved bits of the last information field of the DCI. For example, on the authorized spectrum, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but there is paging information", N = 6 + 8 = 14, and the 6 bits reserved in the last information field in DCI 1-0 and the 8 bits of the Short Messages information field are used. When the Short Messages Indicator information field in the paging DCI 1-0 indicates "there is a short message and there is paging information", N = 6, and the 6 bits reserved in the last information field in DCI1-0 are directly used.

[0108] In mode 5, it is determined based on the reserved bits of the Short Messages information field in the DCI in the unlicensed spectrum and the reserved bits of the last information field of the DCI. For example, in the unlicensed spectrum, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but there is paging information", N = 8 + 8 = 16, and the 8 bits reserved in the last information field in DCI 1-0 and the 8 bits in the Short Messages information field are used. When the Short Messages Indicator information field in the paging DCI 1-0 indicates "there is a short message and there is paging information", N = 8, and the 8 bits reserved in the last information field in DCI1-0 are directly used.

[0109] In method 6, the number of bits is determined based on the last specified number of bits in the Short Messages field in the DCI. For example, N = 6, and the 3rd to 8th bits (a total of 6 bits) of the 8 bits in the Short Messages field in the paging DCI 1-0 are directly used.

[0110] In method 7, it is determined based on the last specified number of bits in the Short Messages information field in the DCI in the authorized spectrum and the reserved bits in the last information field of the DCI. For example, in the authorized spectrum, N=6+6=12, and the last 6-bit information field reserved in the paging DCI 1-0 and the 3rd to 8th bits of the 8-bit Short Messages information field are directly used.

[0111] In mode 8, the last specified number of bits in the Short Messages field of the DCI in the unlicensed spectrum and the reserved bits in the last information field of the DCI are used. For example, in the unlicensed spectrum, N=8+6=14, and the 8 bits reserved in the last information field of the paging DCI 1-0 and the 3rd to 8th bits of the 8 bits in the Short Messages information field are directly used.

[0112] It is understood that, in the embodiments of the present disclosure, the values ​​of N involved in the above methods and the use of the reserved bits in the DCI are only exemplary and not limiting. For example, N can also take other values, for example, N=5, directly using 5 bits of the 6 bits (or 8 bits) reserved in the last information field in the paging DCI 1-0.

[0113] The embodiment of the present disclosure can indicate whether a terminal group has a paging message based on the bit value of each bit. For example, if a bit includes a first value and a second value, the first value is used to indicate that a terminal group has a paging message, and the second value is used to indicate that a terminal group does not have a paging message.

[0114] In one example, a bit value of 1 (or 0) indicates that there is a paging message for a terminal in a terminal group to which one or more terminal IDs belong. A bit value of 0 (or 1) indicates that there is no paging message for a terminal in a terminal group to which one or more terminal IDs belong. When the Short Messages information field in the DCI of the scheduling paging information received by the terminal indicates that there is a paging message, the terminal determines whether it needs to receive and demodulate the PDSCH containing the paging message based on the 1-bit value corresponding to the terminal group to which the terminal ID belongs. If the bit value is 0, it means that there is no paging message for the terminal in the PDSCH, and the terminal does not need to receive and demodulate the PDSCH. If the bit value is 1, the terminal determines that it needs to receive and demodulate the PDSCH.

[0115] In the embodiment of the present disclosure, the terminal group can be represented by a terminal identifier. In other words, the terminal group can be understood as a set of terminal identifier sets, or a set representing a terminal identifier set. In the related art, a terminal identifier usually requires 48 bits to indicate, so in the embodiment of the present disclosure, a terminal identifier set can be represented by a numerical range.

[0116] In one implementation of the embodiment of the present disclosure, when a terminal identification set (terminal group) is represented by a numerical range, the numerical range representing the terminal identification set (terminal group) may be determined by one of the following implementations.

[0117] In one implementation, the bit value range representing the terminal identifier is divided into N groups of value ranges, and each group of value ranges corresponds to a terminal group. For example, the bit representing the terminal identifier is 48 bits, and the total value range of the bit value range representing the terminal identifier is 0 to 2^48-1. If N=6, the value range of 0 to 2^48-1 can be divided into 6 complementary but non-overlapping value ranges, for example, the value range of 0 to 2^48-1 can be divided into

[0118] When the terminal determines the terminal group to which the terminal belongs, the terminal group corresponding to the value range corresponding to the terminal identifier of the terminal can be determined as the terminal group to which the terminal belongs in the N groups of value ranges divided based on the bit value range representing the terminal identifier. For example, if the terminal identifier is 1, then the terminal group to which the terminal belongs can be determined as The terminal group to which the value range corresponds.

[0119] In one implementation, the range of values ​​after the bit value representing the terminal identifier is modulo a specified value is divided into N groups of value ranges, and each group of value ranges corresponds to a terminal group. In an example, assuming N=8, the range of values ​​after the bit value representing the terminal identifier is modulo a specified value is divided into 8 groups of value ranges, and the corresponding value ranges are 0-127, 128-255, 256-383, 384-511, 512-639, 640-767, 768-895, 896-1023. Among them, the specified value for modulo can be 1024.

[0120] When determining the terminal group to which it belongs, the terminal will determine the terminal group corresponding to the corresponding numerical range modulo the terminal identifier of the terminal in the N groups of numerical ranges divided based on the numerical range after the bit value representing the terminal identifier is modulo the specified numerical value as the terminal group to which the terminal belongs. For example, under the above-mentioned terminal grouping method, the terminal can take the bit value corresponding to the terminal identifier of the terminal modulo 1024, and determine its corresponding numerical range and corresponding ID based on the result of the modulo. For example, if the result of taking the bit value corresponding to the terminal identifier of the terminal modulo 1024 is 1002, then the terminal corresponds to the terminal group corresponding to the last bit of the 8 bits indicating whether there is a paging message.

[0121] In one implementation, the terminal identifier is mapped to N terminal groups in the disclosed embodiment. For example, in the disclosed embodiment, a hash algorithm may be used to map the terminal identifier to 1 to N values, each of which corresponds to one bit in the N bits, that is, each value corresponds to a terminal group.

[0122] When the terminal determines the terminal group to which the terminal belongs, the terminal group after the terminal identifier of the terminal is mapped is determined as the terminal group to which the terminal belongs. For example, the terminal uses a certain hash algorithm to map the terminal identifier of the terminal to a certain value m from 1 to N, then the terminal group to which the terminal belongs can be understood as the terminal group corresponding to the mth bit among the N bits.

[0123] It is understandable that in the implementation method of determining the terminal grouping method involved in the above examples of the present disclosure, the terminal identification set corresponding to the terminal identification is evenly divided for explanation, but the embodiment of the present disclosure is not limited to the evenly divided grouping method, and uneven grouping is also possible. For example, in the method of grouping after taking the modulus of the above terminal identification bit, the value range after taking the modulus of the bit value representing the terminal identification with respect to the specified value can also be divided into 8 groups of value ranges, namely 0-127, 128-190, 191-220, 221-511, 512-639, 640-767, 768-895, 896-1023.

[0124] It is understandable that the grouping method of the terminal group is not specifically limited in the embodiments of the present disclosure. However, the network device and the terminal need to determine the grouping method of the terminal group. The grouping method of the terminal group determined in the embodiments of the present disclosure may adopt one or more of the following embodiments:

[0125] In one implementation, the embodiment of the present disclosure may determine the grouping method of the terminal groups based on the protocol, for example, directly agreeing on a fixed grouping method of the terminal groups in the protocol.

[0126] In another implementation manner, the disclosed embodiment may configure the grouping mode of the terminal group through signaling, for example, through RRC signaling or non-access stratum (NAS) signaling.

[0127] In the embodiment of the present disclosure, when configuring the grouping mode of the terminal group through signaling, the network device needs to send the determined grouping mode to the terminal so that the terminal can determine the grouping mode determined by the network device. For example, in one example, after the network device determines the grouping mode, it can send an indication signaling for indicating the grouping mode of the numerical range to the terminal. For example, a numerical value for indicating the critical point of dividing each group of numerical ranges in N groups of numerical ranges is sent to the terminal.

[0128] Among them, in the embodiment of the present disclosure, when determining the grouping method of the terminal group, it can be determined based on whether the number of reserved bits used to indicate whether there is a paging message for the terminal group will change. For example, when the grouping method is determined and the N value is fixed, such as the above-mentioned N value methods 1 / 2 / 3 / 6 / 7 / 8, since the value of N is fixed under different scheduling situations, a grouping method for determining the terminal group based on the protocol can be adopted, and a fixed grouping method for determining the terminal group is agreed by the protocol. Or a set of grouping parameters are configured through signaling, and the grouping parameters are used to indicate a fixed grouping method for determining the terminal group, which can also be understood as the grouping parameters determining a grouping method for the fixed N value.

[0129] For another example, when the grouping method is determined but the N value changes, for example, in the above-mentioned N value methods 4 / 5, since the N value changes under different scheduling situations, different grouping methods need to be determined for different N values. For example, a grouping method based on a protocol to determine the terminal group is adopted, and different grouping methods are determined by a grouping method fixed by a protocol agreement for determining the terminal groups corresponding to different N values, or multiple sets of grouping parameters are configured through signaling, and each set of grouping parameters is used to indicate a grouping method of a terminal group corresponding to a value of N.

[0130] In the disclosed embodiment, when the grouping mode of the terminal group is configured by signaling, it can be understood that the grouping mode of the terminal group is configured by the network device such as the wireless access network device and / or the core network device. Among them, when the network device configures the grouping mode of the terminal group by signaling, the terminal group can be divided based on the terminals existing in the PO, and different terminals can be divided into different terminal groups, and different terminal groups can be indicated by different bits, so that the terminal can accurately determine whether there is a paging message belonging to the terminal, avoiding the situation where the PDSCH corresponding to the terminal group is demodulated and it is found that there is no paging message corresponding to the terminal.

[0131] In an example, a grouping method of dividing the range of values ​​after the bit value representing the terminal identifier is modulo a specified value into N groups of value ranges is used as an example for explanation. Assume that the network device determines that there are 4 terminals (terminal 1, terminal 2, terminal 3 and terminal 4) in the PO, and the results of the terminal identifiers of the 4 terminals after modulo 1024 are 188, 203, 237, and 696 respectively. If the method of equal fixed division is used, terminal 1, terminal 2, and terminal 3 all correspond to the second bit of the 8 bits in the reserved state. When terminal 1, terminal 2, and terminal 3 receive the second bit of the DCI indicating "there is a paging message" in the scheduling paging message on the PO, terminal 1, terminal 2, and terminal 3 determine that they need to receive and demodulate PDSCH. However, the paging message on the PDSCH may be a paging message for one of the terminals (for example, terminal 1). At this time, terminal 2 and terminal 3 do not need to receive and demodulate PDSCH, which wastes the energy of terminal 2 and terminal 3. If the grouping mode of the terminal group is configured by signaling through a base station or core network or other network equipment, the network equipment can classify terminal 1, terminal 2, terminal 3 and terminal 4 into different terminal groups according to the known terminal conditions. For example, the grouping mode is 0-127, 128-190, 191-220, 221-511, 512-639, 640-767, 768-895, 896-1023. In this way, terminal 1, terminal 2, terminal 3 and terminal 4 are classified into different terminal groups. When the corresponding bit is 1, it can accurately indicate that there is a corresponding paging message.

[0132] It is understandable that, in the disclosed embodiment, only a base station or a core network or other network device can determine the terminal to be paged in a terminal group. The terminal cannot determine whether only the terminal is paged or other terminals are paged in the terminal group to which it belongs. Therefore, in the case where a terminal group includes a terminal and the bit in the reserved state indicates the presence of a paging message, the terminal still needs to receive and demodulate the PDSCH to determine whether there is a PDSCH of the terminal.

[0133] The paging method provided in the embodiment of the present disclosure utilizes the reserved bit in the DCI of the scheduled paging message to notify the terminal to a certain extent whether there is a paging message corresponding to the terminal in the DCI of the scheduled paging message. If the DCI shows that there is no paging message corresponding to the terminal, the terminal does not need to demodulate the PDSCH, which can play a role in energy saving.

[0134] It is understandable that the paging method provided in the embodiment of the present disclosure can be applied to the process of interaction between the terminal and the network device. For the process of interaction between the terminal and the network device to implement paging in the unlicensed frequency band or the licensed frequency band, please refer to the relevant description of the above embodiment, which will not be repeated here.

[0135] Based on the same concept, an embodiment of the present disclosure also provides a paging device.

[0136] It is understandable that the user paging device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0137] Figure 4 FIG. 1 is a block diagram of a paging device according to an exemplary embodiment. Figure 4 The paging device 100 is applied to a network device, and the paging device 100 includes a processing unit 101 and a sending unit 102 .

[0138] The processing unit 101 is configured to determine DCI, where the DCI includes one or more bits, each of which indicates whether a paging message exists for a terminal group or not. The sending unit 102 is configured to send the DCI.

[0139] In one implementation, the processing unit 101 determines at least some of the bits in the DCI that are in a reserved state as one or more bits indicating whether there is a paging message for the terminal group.

[0140] In one implementation, the DCI is a DCI for scheduling a paging message.

[0141] In another implementation, a first value of each of the one or more bits is used to indicate that a paging message exists for a terminal group, and a second value of each of the one or more bits is used to indicate that a paging message does not exist for a terminal group.

[0142] In another embodiment, the terminal group is determined in at least one of the following ways:

[0143] Divide the bit value range representing the terminal identifier into N groups of value ranges, each of which corresponds to a terminal group. Divide the value range of the bit value representing the terminal identifier modulo a specified value into N groups of value ranges, each of which corresponds to a terminal group. Map the terminal identifier to N terminal groups. Where N is a positive integer.

[0144] In yet another embodiment, N is determined based on one or more bits indicating a terminal group and is less than or equal to the number of bits in a reserved state in the DCI.

[0145] In another implementation manner, N is determined in the following manner:

[0146] In method 1, it is determined based on the reserved bits of the last information field of the DCI in the authorized spectrum. For example, on the authorized spectrum, if the number of reserved bits of the last information field of the DCI for scheduling paging messages is 6, then N=6 can be determined, and the 6 bits reserved in the last information field of DCI 1-0 are directly used.

[0147] In method 2, it is determined based on the reserved bits of the last information field of DCI in the unlicensed spectrum. For example, in the unlicensed spectrum, the number of reserved bits of the last information field of DCI for scheduling paging messages is 8, then N=8 can be determined, and the 8 bits reserved in the last information field of DCI 1-0 are directly used.

[0148] In mode 3, it is determined based on the reserved bits in the Short Messages information field in the DCI. For example, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but paging information", there are reserved bits in DCI 1-0, and N=8 is determined, and 8 bits of the Short Messages information field are used.

[0149] In mode 4, it is determined based on the reserved bits of the Short Messages information field in the DCI in the authorized spectrum and the reserved bits of the last information field of the DCI. For example, on the authorized spectrum, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but there is paging information", N = 6 + 8 = 14, and the 6 bits reserved in the last information field in DCI 1-0 and the 8 bits of the Short Messages information field are used. When the Short Messages Indicator information field in the paging DCI 1-0 indicates "there is a short message and there is paging information", N = 6, and the 6 bits reserved in the last information field in DCI1-0 are directly used.

[0150] In mode 5, it is determined based on the reserved bits of the Short Messages information field in the DCI in the unlicensed spectrum and the reserved bits of the last information field of the DCI. For example, in the unlicensed spectrum, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but there is paging information", N = 8 + 8 = 16, and the 8 bits reserved in the last information field in DCI 1-0 and the 8 bits in the Short Messages information field are used. When the Short Messages Indicator information field in the paging DCI 1-0 indicates "there is a short message and there is paging information", N = 8, and the 8 bits reserved in the last information field in DCI1-0 are directly used.

[0151] In method 6, the number of bits is determined based on the last specified number of bits in the Short Messages field in the DCI. For example, N = 6, and the 3rd to 8th bits (a total of 6 bits) of the 8 bits in the Short Messages field in the paging DCI 1-0 are directly used.

[0152] In method 7, it is determined based on the last specified number of bits in the Short Messages information field in the DCI in the authorized spectrum and the reserved bits in the last information field of the DCI. For example, in the authorized spectrum, N=6+6=12, and the last 6-bit information field reserved in the paging DCI 1-0 and the 3rd to 8th bits of the 8-bit Short Messages information field are directly used.

[0153] In mode 8, the last specified number of bits in the Short Messages field of the DCI in the unlicensed spectrum and the reserved bits in the last information field of the DCI are used. For example, in the unlicensed spectrum, N=8+6=14, and the 8 bits reserved in the last information field of the paging DCI 1-0 and the 3rd to 8th bits of the 8 bits in the Short Messages information field are directly used.

[0154] In yet another implementation, the processing unit 101 is further configured to: determine a grouping method of the terminal group.

[0155] In another embodiment, the processing unit 101 determines the grouping method of the terminal group by one or a combination of the following methods:

[0156] The grouping method of the terminal group is determined based on the protocol. The grouping method of the terminal group is configured based on the radio resource control signaling or the non-access layer signaling.

[0157] In yet another implementation, the sending unit 102 is further configured to: if the grouping mode of the terminal group is configured based on the radio resource control signaling or the non-access layer signaling, send the grouping mode to the terminal.

[0158] Figure 5 FIG. 1 is a block diagram of a paging device according to an exemplary embodiment. Figure 5 The paging device 200 is applied to a terminal, and includes a receiving unit 201 and a processing unit 202 .

[0159] The receiving unit 201 is configured to obtain DCI, wherein the DCI includes one or more bits, each of which indicates that a paging message exists or does not exist for a terminal group. The processing unit is configured to determine the terminal group to which the terminal belongs, and determine whether to receive the paging message or not to receive the paging message based on the terminal group to which the terminal belongs.

[0160] In one implementation, the one or more bits indicating whether a paging message exists for the terminal group are at least part of the bits in a reserved state.

[0161] In one implementation, the DCI is a DCI for scheduling a paging message.

[0162] In another implementation, a first value of each of the one or more bits is used to indicate that a paging message exists for a terminal group, and a second value of each of the one or more bits is used to indicate that a paging message does not exist for a terminal group.

[0163] In another implementation manner, the processing unit 202 determines the terminal group to which the terminal belongs by using one or a combination of the following methods, including:

[0164] In the N groups of numerical ranges divided based on the bit value range representing the terminal identifier, the terminal group corresponding to the numerical range corresponding to the terminal identifier of the terminal is determined as the terminal group to which the terminal belongs. In the N groups of numerical ranges divided based on the numerical range after taking the modulus of the specified numerical value after taking the modulus of the bit value representing the terminal identifier, the terminal group corresponding to the numerical range corresponding to the terminal identifier of the terminal is determined as the terminal group to which the terminal belongs. The terminal group after the terminal identifier of the terminal is mapped is determined as the terminal group to which the terminal belongs. Wherein, N is a positive integer.

[0165] In yet another embodiment, N is determined based on one or more bits indicating a terminal group and is less than or equal to the number of bits in a reserved state in the DCI.

[0166] In another embodiment, N is determined by one or more of the following methods:

[0167] In method 1, it is determined based on the reserved bits of the last information field of the DCI in the authorized spectrum. For example, on the authorized spectrum, if the number of reserved bits of the last information field of the DCI for scheduling paging messages is 6, then N=6 can be determined, and the 6 bits reserved in the last information field of DCI 1-0 are directly used.

[0168] In method 2, it is determined based on the reserved bits of the last information field of DCI in the unlicensed spectrum. For example, in the unlicensed spectrum, the number of reserved bits of the last information field of DCI for scheduling paging messages is 8, then N=8 can be determined, and the 8 bits reserved in the last information field of DCI 1-0 are directly used.

[0169] In mode 3, it is determined based on the reserved bits in the Short Messages information field in the DCI. For example, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but paging information", there are reserved bits in DCI 1-0, and N=8 is determined, and 8 bits of the Short Messages information field are used.

[0170] In mode 4, it is determined based on the reserved bits of the Short Messages information field in the DCI in the authorized spectrum and the reserved bits of the last information field of the DCI. For example, on the authorized spectrum, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but there is paging information", N = 6 + 8 = 14, and the 6 bits reserved in the last information field in DCI 1-0 and the 8 bits of the Short Messages information field are used. When the Short Messages Indicator information field in the paging DCI 1-0 indicates "there is a short message and there is paging information", N = 6, and the 6 bits reserved in the last information field in DCI1-0 are directly used.

[0171] In mode 5, it is determined based on the reserved bits of the Short Messages information field in the DCI in the unlicensed spectrum and the reserved bits of the last information field of the DCI. For example, in the unlicensed spectrum, when the Short Messages Indicator information field in the paging DCI 1-0 indicates "no short message, but there is paging information", N = 8 + 8 = 16, and the 8 bits reserved in the last information field in DCI 1-0 and the 8 bits in the Short Messages information field are used. When the Short Messages Indicator information field in the paging DCI 1-0 indicates "there is a short message and there is paging information", N = 8, and the 8 bits reserved in the last information field in DCI1-0 are directly used.

[0172] In method 6, the number of bits is determined based on the last specified number of bits in the Short Messages field in the DCI. For example, N = 6, and the 3rd to 8th bits (a total of 6 bits) of the 8 bits in the Short Messages field in the paging DCI 1-0 are directly used.

[0173] In method 7, it is determined based on the last specified number of bits in the Short Messages information field in the DCI in the authorized spectrum and the reserved bits in the last information field of the DCI. For example, in the authorized spectrum, N=6+6=12, and the last 6-bit information field reserved in the paging DCI 1-0 and the 3rd to 8th bits of the 8-bit Short Messages information field are directly used.

[0174] In mode 8, the last specified number of bits in the Short Messages field of the DCI in the unlicensed spectrum and the reserved bits in the last information field of the DCI are used. For example, in the unlicensed spectrum, N=8+6=14, and the 8 bits reserved in the last information field of the paging DCI 1-0 and the 3rd to 8th bits of the 8 bits in the Short Messages information field are directly used.

[0175] In yet another implementation, the processing unit 202 is further configured to: determine a grouping method of the terminal group.

[0176] In another implementation manner, the processing unit 202 determines the grouping method of the terminal groups by using one or a combination of the following methods:

[0177] Determine the grouping mode of the terminal group based on the protocol. Obtain radio resource control signaling or non-access layer signaling, and determine the grouping mode of the terminal group based on the radio resource control signaling or the non-access layer signaling.
