Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to a method, apparatus, communication device and storage medium for group paging. Background Art

[0002] Paging is an important function of wireless communication. The function of paging is to notify the terminal being paged to respond to the network according to the needs of the network. The base station and the terminal will agree on a paging time (PO, Paging Occasion). The base station will send a paging message at the paging time, and the terminal will receive the paging message at the corresponding paging time.

[0003] In the related art, a group paging method is used to page a terminal. The network can page all terminals in a group by sending a paging message, without sending a paging message to each terminal separately. After receiving the group paging message, the terminal determines whether it belongs to the paged group. If it does, it responds to the group paging message. If it does not, it ignores the group paging message. Summary of the invention

[0088] Please refer to Figure 1 , which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on mobile communication technology, and the wireless communication system may include: a plurality of user equipments 110 and a plurality of base stations 120 .

[0089] Among them, the user equipment 110 can be a device that provides voice and / or data connectivity to the user.

[0094] Here, the above-mentioned user equipment can be considered as the terminal equipment of the following embodiments.

[0095] In some embodiments, the wireless communication system may further include a network management device 130 .

[0096] Several base stations 120 are respectively connected to a network management device 130. The network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0097] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

[0098] In order to better understand the technical solution described in any embodiment of the present disclosure, first, the scenario of the group paging terminal in the related art is described:

[0099] In one embodiment, if paging groups are not performed, all terminals will be awakened at the paging time. In one embodiment, since the probability of terminals being paged in the corresponding time period at the paging time is different, terminals with low paging probabilities will also be woken up by mistake, resulting in unnecessary power consumption. Therefore, it is necessary to paging groups the terminals and page the terminals in the paging grouping manner.

[0100] In one embodiment, the paging group information may be carried in the paging downlink control information (DCI) or in the paging early indication (PEI). Regardless of the grouping method used, the terminal and the network (including the base station and the core network) need to reach an agreement on the group in which the terminal is located before the paging message can be sent to the terminal normally.

[0101] In one embodiment, the terminal and the core network predetermine a paging probability Pnas, and the base station broadcasts information including the relationship between the probability and the paging group, so that the terminal can determine the paging group in which the terminal is located according to the received information.

[0102] In one embodiment, when the core network device sends a paging message to the base station, the core network will notify the base station of the paging probability of the terminal to facilitate the base station to determine the paging group of the terminal. In one embodiment, if the core network does not notify the base station of the paging probability of the terminal, the terminal will select a predetermined paging group.

[0103] In one embodiment, a paging probability Pnas is pre-negotiated between the terminal and the core network, and the base station broadcasts the relationship between Pnas and the group, so that the terminal can determine the group to be paged. When the paging message arrives at the base station from the core network, the core network will also notify the base station of the Pnas of the terminal, which is used by the base station to determine the group of the terminal. In this way, the three network elements of the terminal, the base station, and the core network reach a consensus on the group confirmation.

[0104] In one embodiment, see Figure 2 , is a DCI format for indicating PEI of a sub-paging group, showing how PEI indicates group information. Here, PEI can be associated with multiple POs, and Nsg bits are required for each PO to indicate the paging group information.

[0105] However, some terminals may only support the capability of PEI without indicating paging packets, but not support the capability of PEI with indicating sub-paging packets. Therefore, it is necessary to consider how to design the case of not supporting indicating sub-paging packets and the behavior of the terminal.

[0106] like Figure 3 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station, and the method includes:

[0107] Step 31: Sending a paging advance indication PEI;

[0108] The PEI includes at least one of the following: a first type of PEI and a second type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group; the second type of PEI is a PEI that indicates a sub-paging group.

[0109] Here, the terminal can be but is not limited to a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU, RoadSide Unit), a smart home terminal, an industrial sensor device and / or a medical device, etc.

[0110] In an application scenario, the terminal may be a terminal that supports the second type of PEI, where the terminal supports the second type of PEI and can identify the second type of PEI after receiving the PEI and / or can perform a paging operation based on the second type of PEI. In an application scenario, the terminal may be a terminal that does not support the second type of PEI, where the terminal does not support the second type of PEI and cannot identify the second type of PEI after receiving the PEI and / or cannot perform a paging operation based on the second type of PEI. In some application scenarios, among the terminals accessed in the network, some terminals are terminals that support the second type of PEI, and some terminals are terminals that do not support the second type of PEI. This is not limited here. Here, it should be noted that in response to the terminal supporting the second type of PEI, the terminal also supports the first type of PEI. Here, whether the terminal supports the first type of PEI scenario is similar to the above scenario. It should be noted that the terminal may not support both the first type of PEI and the second type of PEI.

[0111] The base station involved in the present disclosure may be an access device for a terminal to access a network. Here, the base station may be various types of base stations, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations. Here, the base station may configure different types of PEIs according to the capability information of the PEIs supported by the terminal.

[0112] In one embodiment, group paging may be as follows: terminals are divided into different groups; the network pages all terminals in a group by sending a group paging message, without sending a paging message to each terminal separately; after receiving the group paging message, the terminal determines whether it belongs to the paged group; if it belongs to the paged group, it responds to the group paging message; if it does not belong to the paged group, it ignores the group paging message.

[0113] In one embodiment, there may be multiple groups for group paging. Here, different groups may be configured with different paging resources. The terminal may belong to one of the multiple groups. In response to the determination of the paging group to which the terminal belongs, the terminal may monitor the paging message on the paging resource indicated by the paging group. Here, which group the terminal belongs to may be determined by the base station or by a core network device in the core network. It should be noted that the predetermined group may also be divided into multiple sub-paging groups. Of course, the group here may refer to the sub-paging group, which is not limited here.

[0114] In one embodiment, there may be multiple sub-paging groups for group paging. The terminals included in the sub-paging group may be determined based on the probability of the terminal being paged and the paging level to which the terminal belongs. In one embodiment, the terminal may determine the sub-paging group to which the terminal belongs based on the paging probability of the terminal being paged. In one embodiment, in response to the paging probability of the terminal being paged being less than a probability threshold, it is determined that the terminal belongs to the first sub-paging group; or, in response to the paging probability of the terminal being paged being greater than a probability threshold, it is determined that the terminal belongs to the second sub-paging group. Here, the paging resources configured for the first sub-paging group and the second sub-paging group may be different. It should be noted that the paging resources configured for the first group and the second group may also be the same.

[0115] In the embodiment of the present disclosure, the base station can send two different types of PEI. Here, the PEI is used for the terminal to perform a paging operation. Here, the PEI indicating the sub-paging packet can be a PEI carrying the sub-paging packet information.

[0116] It should be noted that the terminal can report the capability information of the PEI supported by the terminal; the base station can determine what type of PEI to send to the terminal based on the capability information. For example, if the capability information indicates that the terminal only supports the first type of PEI, the base station can send the first type of PEI. Alternatively, if the capability information indicates that the terminal supports the first type of PEI and the second type of PEI, the base station can send the second type of PEI or the base station sends the first type of PEI. Alternatively, the capability information indicates that the terminal supports the first type of PEI and the second type of PEI, and the base station sends the first type of PEI and the second type of PEI. Here, after receiving the first type of PEI and / or the second type of PEI, the terminal can determine which type of PEI to use based on the terminal policy and / or the terminal capability. For example, the terminal preferentially uses the second type of PEI based on the terminal policy. This is not limited here.

[0117] In one embodiment, a base station receives capability information reported by a terminal, wherein the capability information indicates that the terminal supports a first type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes a first type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group. After receiving the first type of PEI, the terminal performs a paging operation based on the first type of PEI. Here, performing a paging operation may be determining whether a paging message sent by the base station needs to be responded to.

[0118] In one embodiment, the base station receives capability information reported by the terminal, wherein the capability information indicates that the terminal supports the second type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes the second type of PEI; the second type of PEI is a PEI indicating a sub-paging group. After receiving the second type of PEI, the terminal performs a paging operation based on the second type of PEI. Here, performing a paging operation may be determining whether a paging message sent by the base station needs to be responded to.

[0119] In one embodiment, a base station receives capability information reported by a terminal, wherein the capability information indicates that the terminal supports a second type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes a first type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group. After receiving the first type of PEI, the terminal performs a paging operation based on the first type of PEI. Here, performing a paging operation may be determining whether a paging message sent by a base station needs to be responded to. Here, it should be noted that in response to the terminal supporting the second type of PEI, the terminal may monitor the first type of PEI.

[0120] In one embodiment, the base station receives capability information reported by the terminal, wherein the capability information indicates that the terminal supports the second type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes a first type of PEI and a second type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group; the second type of PEI is a PEI that indicates a sub-paging group. After receiving the first type of PEI and the second type of PEI, the terminal performs a paging operation based on the first type of PEI or the second type of PEI. Here, performing a paging operation may be determining whether a paging message sent by a base station needs to be responded to. It should be noted that after receiving two different types of PEIs, the terminal may determine which type of PEI to use to perform a paging operation based on a terminal policy, a predetermined protocol provision, or a default configuration, which is not limited here.

[0121] Here, the indication of the sub-paging packet may be information that carries the sub-paging packet. It should be noted that the type of PEI involved in this article may be distinguished and indicated by an explicit indication or an implicit indication. Here, the indication by explicit indication may be that the PEI is directly indicated by the set dedicated information field. For example, the information field contains 1 bit, and when the information field is taken as "0", it indicates that the PEI is a first type of PEI; when the information field is taken as "1", it indicates that the PEI is a second type of PEI. Here, the indication by implicit indication may be that a dedicated information field is not set, but that different types of paging radio network temporary identifiers P-RNTI, public search spaces, control resource sets Coreset, and the format of the DCI for issuing PEI are used for PEI. For example, if the PEI is scrambled by the first P-RNTI, it indicates that the PEI is a first type of PEI; if the PEI is scrambled by the second P-RNTI, it indicates that the PEI is a second type of PEI. In one embodiment, the first type of PEI and the second type of PEI may not reuse the carrying mode, for example, the first type of PEI and the second type of PEI may be carried through different DCIs, the first type of PEI is carried through the first DCI, and the second type of PEI is carried through the second DCI.

[0122] In one embodiment, the first type of PEI and the second type of PEI may multiplex the bearer mode. For example, the first type of PEI and the second type of PEI may be carried by the same DCI. In one embodiment, the first type of PEI and the second type of PEI may not multiplex the bearer mode, for example, the first type of PEI and the second type of PEI may be carried by different DCIs, the first type of PEI is carried by the first DCI, and the second type of PEI is carried by the second DCI.

[0123] In an embodiment of the present disclosure, a paging advance indication PEI is sent; wherein the PEI includes at least one of the following: a first type of PEI and a second type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging packet; the second type of PEI is a PEI that indicates a sub-paging packet. Here, since the base station can send both the first type of PEI and the second type of PEI, regardless of whether the terminal receiving the PEI can identify the PEI indicating the sub-paging packet, the terminal can receive the PEI that the terminal can identify. Compared with the method in which the base station only sends the second type of PEI, the present disclosure can send two different types of PEI to adapt to the capabilities of the terminal, thereby improving network compatibility.

[0124] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0125] In one embodiment, the first type of PEI and the second type of PEI are not multiplexed. Here, the first type of PEI and the second type of PEI may be carried by different DCIs. For example, the first type of PEI is carried by the first DCI, and the second type of PEI is carried by the second DCI.

[0126] In one embodiment, the paging radio network temporary identifier P-RNTI of the first type of PEI and the second type of PEI are different;

[0127] and / or,

[0128] The common search space of the first type of PEI and the second type of PEI is different;

[0129] and / or,

[0130] The control resource set Coreset of the first type of PEI and the second type of PEI is different;

[0131] and / or,

[0132] The formats of downlink control information DCI of the first type PEI and the second type PEI are different.

[0133] In one embodiment, the first type of PEI is encrypted with the first P-RNTI, and the second type of PEI is encrypted with the second P-RNTI. After receiving the PEI, the terminal can determine whether the PEI is the first type of PEI or the second type of PEI according to the P-RNTI used for encryption. For example, if the P-RNTI is the first P-RNTI, the PEI is the first type of PEI. For another example, if the P-RNTI is the second P-RNTI, the PEI is the second type of PEI.

[0134] In one embodiment, the public search space of the first type of PEI is the first public search space, and the public search space of the second type of PEI is the second public search space, and the terminal can obtain the first type of PEI and the second type of PEI in different public search spaces.

[0135] In one embodiment, the control resource set of the first type of PEI is the first control resource set, and the control resource set of the second type is the second control resource set, then the terminal can determine the first type of PEI and the second type of PEI based on different control resource sets. For example, if the control resource set is the first control resource set, then the PEI is the first type of PEI. For another example, if the control resource set is the second control resource set, then the PEI is the second type of PEI.

[0136] In one embodiment, the format of the DCI carrying the first type of PEI is the first DCI format, and the format of the DCI carrying the second type of PEI is the second DCI format. After receiving the DCI carrying the PEI, the terminal determines the first type of PEI and the second type of PEI according to the format of the DCI. Here, the formats of different DCIs can be determined according to whether the DCI carries or does not carry a predetermined information field. In one embodiment, if the DCI carries a predetermined information field, the format of the DCI is determined to be the first DCI format; or, if the DCI does not carry the predetermined information field, the format of the DCI is determined to be the second DCI format.

[0137] In one embodiment, the first type of PEI and the second type of PEI are multiplexed. Here, the first type of PEI and the second type of PEI can be carried by the same DCI. For example, the first type of PEI and the second type of PEI are carried by the first DCI.

[0138] In one embodiment, the DCI includes a predetermined information field; wherein the predetermined information field includes a first subfield and / or a second subfield; the first subfield indicates information of a first type of PEI; and the second subfield indicates information of a second type of PEI.

[0139] In one embodiment, the predetermined information domain includes a first subdomain and a second subdomain. After receiving the DCI, the terminal can determine that the received PEI includes a first type of PEI and a second type of PEI according to the predetermined information domain. The terminal can select a PEI from the first type of PEI and the second type of PEI to perform a paging operation. It should be noted that after receiving two different types of PEIs, the terminal can determine which type of PEI to use to perform a paging operation according to the terminal policy, the predetermined protocol, or the default configuration, which is not limited here. In one embodiment, the predetermined information domain includes the first subdomain and does not include the second subdomain. After receiving the DCI, the terminal can determine that the received PEI does not indicate sub-paging group information according to the predetermined information domain, that is, the received PEI is a first type of PEI. The terminal can perform a paging operation based on the first type of PEI.

[0140] In one embodiment, the predetermined information domain includes the second subdomain and does not include the first subdomain. After receiving the DCI, the terminal can determine the received PEI indication sub-paging group information according to the predetermined information domain, that is, the received PEI is a second type of PEI. The terminal can perform a paging operation based on the second type of PEI. In one embodiment, a terminal supporting the second type of PEI can perform a paging operation based on the second type of PEI.

[0141] In one embodiment, the DCI includes a predetermined information field, wherein a value of the predetermined information field is used to indicate that the PEI carried by the DCI is a first type of PEI, or that the PEI carried by the DCI is a second type of PEI.

[0142] In one embodiment, the value of the predetermined information field is a first value, and the PEI carried by the DCI is a first type of PEI. After receiving the DCI whose predetermined information field value is the first value, the terminal determines that the received PEI is a first type of PEI. The terminal can perform a paging operation based on the first type of PEI. Here, the first value can be a value range.

[0143] In one embodiment, the value of the predetermined information field is a second value, and the PEI carried by the DCI is a second type of PEI. After receiving the DCI whose predetermined information field value is the second value, the terminal determines that the received PEI is a second type of PEI. The terminal can perform a paging operation based on the second type of PEI. Here, the second value can be a value range.

[0144] In one embodiment, the predetermined information field may also use additional reserved bits to indicate the first type of PEI. That is, on the basis of the predetermined information field indicating the first type of PEI, additional bits are reserved for use as the predetermined information field. For example, 3 bits are reserved, and when the value is "000", it is used to indicate that the first type of PEI information is carried.

[0145] like Figure 4 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station, and the method includes:

[0146] Step 41: Send a system message, wherein the system message is used to at least indicate that the PEI is a first type of PEI or a second type of PEI.

[0147] In one embodiment, the base station sends a system message, wherein the system message indicates that the PEI is a first type of PEI. After receiving the system message, the terminal determines that the PEI sent by the base station is a first type of PEI according to the indication of the system message. The base station sends the PEI to the terminal. After receiving the PEI, the terminal determines that the PEI is a first type of PEI. Both the terminal supporting the second type of PEI and the terminal not supporting the second type of PEI can perform paging operations based on the first type of PEI.

[0148] In one embodiment, the base station sends a system message, wherein the system message indicates that the PEI is a second type of PEI. After receiving the system message, the terminal determines that the PEI sent by the base station is a second type of PEI according to the indication of the system message. The base station sends the PEI to the terminal. After receiving the PEI, the terminal determines that the PEI is a second type of PEI. A terminal supporting the second type of PEI can perform a paging operation based on the second type of PEI. As an embodiment, it can be considered that a terminal supporting the second type of PEI can monitor the first type of PEI.

[0149] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0150] like Figure 5 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station, and the method includes:

[0151] Step 51: receiving capability information of supporting the first type of PEI sent by the terminal;

[0152] and / or,

[0153] The receiving terminal sends capability information indicating whether it supports the second type of PEI.

[0154] In one embodiment, the base station receives capability information of supporting the first type of PEI sent by the terminal; and the base station sends the first type of PEI to the terminal.

[0155] In one embodiment, the base station receives capability information of supporting the second type of PEI sent by the terminal; the base station sends the second type of PEI to the terminal. In one embodiment, the base station receives capability information of supporting the second type of PEI sent by the terminal; the base station sends the first type of PEI and the second type of PEI to the terminal. It should be noted that after receiving two different types of PEI, the terminal may determine which type of PEI to use to perform the paging operation according to the terminal policy, the predetermined protocol, or the default configuration, which is not limited here.

[0156] In one embodiment, after receiving the capability information of supporting the first type of PEI sent by the terminal, the base station receives the capability information of supporting the second type of PEI sent by the terminal. The base station sends the second type of PEI to the terminal. In one embodiment, after receiving the capability information of supporting the first type of PEI sent by the terminal, the base station receives the capability information of supporting the second type of PEI sent by the terminal. The base station sends the first type of PEI and the second type of PEI to the terminal. It should be noted that after the terminal receives two different types of PEI, the type of PEI used to perform the paging operation can be determined according to the terminal policy, or it can be specified by a predetermined protocol, or it can be a default configuration, which is not limited here. In one embodiment, a terminal that does not support the second type of PEI can also monitor the second type of PEI, that is, ignore the value of the specific sub-paging group, that is, any sub-paging group can wake itself up.

[0157] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0158] like Figure 6 As shown, this embodiment provides a method for group paging, wherein the method is executed by a terminal, and the method includes:

[0159] Step 61, receiving PEI;

[0160] The PEI includes at least one of the following: a first type of PEI and a second type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group; the second type of PEI is a PEI that indicates a sub-paging group.

[0161] Here, the terminal may be, but is not limited to, a mobile phone, a wearable device, a vehicle terminal, a roadside unit (RSU, RoadSide Unit), a smart home terminal, an industrial sensor device and / or a medical device, etc. In an application scenario, the terminal may be a terminal that supports the second type of PEI, and here, the terminal supports the second type of PEI, which may be that after receiving the PEI, the terminal can identify the second type of PEI and / or can perform a paging operation based on the second type of PEI. In an application scenario, the terminal may be a terminal that does not support the second type of PEI, and here, the terminal does not support the second type of PEI, which may be that after receiving the PEI, the second type of PEI cannot be identified and / or cannot perform a paging operation based on the second type of PEI. In some application scenarios, among the terminals accessed in the network, some terminals are terminals that support the second type of PEI, and some terminals are terminals that do not support the second type of PEI. This is not limited here. Here, it should be noted that in response to the terminal supporting the second type of PEI, the terminal also supports the first type of PEI. Here, whether the terminal supports the first type of PEI scenario is similar to the above scenario. It should be noted that the terminal may not support both the first type of PEI and the second type of PEI.

[0162] The base station involved in the present disclosure may be an access device for a terminal to access a network. Here, the base station may be various types of base stations, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations. Here, the base station may configure different types of PEIs according to the capability information of the PEIs supported by the terminal.

[0163] In one embodiment, group paging may be as follows: terminals are divided into different groups; the network pages all terminals in a group by sending a group paging message, without sending a paging message to each terminal separately; after receiving the group paging message, the terminal determines whether it belongs to the paged group; if it belongs to the paged group, it responds to the group paging message; if it does not belong to the paged group, it ignores the group paging message.

[0164] In one embodiment, there may be multiple groups for group paging. Here, different groups may be configured with different paging resources. The terminal may belong to one of the multiple groups. In response to the determination of the paging group to which the terminal belongs, the terminal may monitor the paging message on the paging resource indicated by the paging group. Here, which group the terminal belongs to may be determined by the base station or by a core network device in the core network. It should be noted that the predetermined group may also be divided into multiple sub-paging groups. Of course, the group here may refer to the sub-paging group, which is not limited here.

[0165] In one embodiment, there may be multiple sub-paging groups for group paging. The terminals included in the sub-paging group may be determined based on the probability of the terminal being paged and the paging level to which the terminal belongs. In one embodiment, the terminal may determine the sub-paging group to which the terminal belongs based on the paging probability of the terminal being paged. In one embodiment, in response to the paging probability of the terminal being paged being less than a probability threshold, it is determined that the terminal belongs to the first sub-paging group; or, in response to the paging probability of the terminal being paged being greater than a probability threshold, it is determined that the terminal belongs to the second sub-paging group. Here, the paging resources configured for the first sub-paging group and the second sub-paging group may be different. It should be noted that the paging resources configured for the first group and the second group may also be the same.

[0166] In the embodiment of the present disclosure, the terminal can receive two different types of PEIs sent by the base station. Here, the PEI is used by the terminal to perform a paging operation. Here, the PEI indicating the sub-paging packet can be a PEI carrying sub-paging packet information.

[0167] It should be noted that the terminal can report the capability information of the PEI supported by the terminal; the base station can determine what type of PEI to send to the terminal based on the capability information. For example, if the capability information indicates that the terminal only supports the first type of PEI, the base station can send the first type of PEI. Alternatively, if the capability information indicates that the terminal supports the first type of PEI and the second type of PEI, the base station can send the second type of PEI or the base station sends the first type of PEI. Alternatively, the capability information indicates that the terminal supports the first type of PEI and the second type of PEI, and the base station sends the first type of PEI and the second type of PEI. Here, after receiving the first type of PEI and / or the second type of PEI, the terminal can determine which type of PEI to use based on the terminal policy and / or the terminal capability. For example, the terminal preferentially uses the second type of PEI based on the terminal policy. This is not limited here.

[0168] In one embodiment, the terminal reports capability information, wherein the capability information indicates that the terminal supports a first type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes a first type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group. After receiving the first type of PEI, the terminal performs a paging operation based on the first type of PEI. Here, performing a paging operation may be determining whether a paging message sent by the base station needs to be responded to.

[0169] In one embodiment, the terminal reports capability information, wherein the capability information indicates that the terminal supports the second type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes the second type of PEI; the second type of PEI is a PEI indicating a sub-paging group. After receiving the second type of PEI, the terminal performs a paging operation based on the second type of PEI. Here, performing a paging operation may be determining whether a paging message sent by the base station needs to be responded to.

[0170] In one embodiment, the terminal reports capability information, wherein the capability information indicates that the terminal supports the second type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes a first type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group. After receiving the first type of PEI, the terminal performs a paging operation based on the first type of PEI. Here, performing a paging operation may be determining whether a paging message sent by a base station needs to be responded to. Here, it should be noted that in response to the terminal supporting the second type of PEI, the terminal can monitor the first type of PEI.

[0171] In one embodiment, the terminal reports capability information, wherein the capability information indicates that the terminal supports the second type of PEI. The base station sends a paging advance indication PEI according to the capability information; wherein the PEI includes a first type of PEI and a second type of PEI; the first type of PEI is a PEI that does not indicate a sub-paging group; the second type of PEI is a PEI that indicates a sub-paging group. After receiving the first type of PEI and the second type of PEI, the terminal performs a paging operation based on the first type of PEI or the second type of PEI. Here, performing a paging operation may be determining whether a paging message sent by a base station needs to be responded to. It should be noted that after receiving two different types of PEIs, the terminal may determine which type of PEI to use to perform a paging operation based on a terminal policy, a predetermined protocol provision, or a default configuration, which is not limited here.

[0172] Here, the indication of the sub-paging packet may be information that carries the sub-paging packet. It should be noted that the type of PEI involved in this article may be distinguished and indicated by an explicit indication or an implicit indication. Here, the indication by explicit indication may be that the PEI is directly indicated by the set dedicated information field. For example, the information field contains 1 bit, and when the information field is taken as "0", it indicates that the PEI is a first type of PEI; when the information field is taken as "1", it indicates that the PEI is a second type of PEI. Here, the indication by implicit indication may be that a dedicated information field is not set, but that different types of paging radio network temporary identifiers P-RNTI, public search spaces, control resource sets Coreset, and the format of the DCI for issuing PEI are used for PEI. For example, if the PEI is scrambled by the first P-RNTI, it indicates that the PEI is a first type of PEI; if the PEI is scrambled by the second P-RNTI, it indicates that the PEI is a second type of PEI. In one embodiment, the first type of PEI and the second type of PEI may not reuse the carrying mode, for example, the first type of PEI and the second type of PEI may be carried through different DCIs, the first type of PEI is carried through the first DCI, and the second type of PEI is carried through the second DCI.

[0173] In one embodiment, the first type of PEI and the second type of PEI may multiplex the bearer mode. For example, the first type of PEI and the second type of PEI may be carried by the same DCI.

[0181] and / or,

[0182] The formats of downlink control information DCI of the first type PEI and the second type PEI are different.

[0183] In one embodiment, the first type of PEI is encrypted with the first P-RNTI, and the second type of PEI is encrypted with the second P-RNTI. After receiving the PEI, the terminal can determine whether the PEI is the first type of PEI or the second type of PEI according to the P-RNTI used for encryption. For example, if the P-RNTI is the first P-RNTI, the PEI is the first type of PEI. For another example, if the P-RNTI is the second P-RNTI, the PEI is the second type of PEI.

[0184] In one embodiment, the public search space of the first type of PEI is the first public search space, and the public search space of the second type of PEI is the second public search space, and the terminal can obtain the first type of PEI and the second type of PEI in different public search spaces.

[0185] In one embodiment, the control resource set of the first type of PEI is the first control resource set, and the control resource set of the second type is the second control resource set, then the terminal can determine the first type of PEI and the second type of PEI based on different control resource sets. For example, if the control resource set is the first control resource set, then the PEI is the first type of PEI. For another example, if the control resource set is the second control resource set, then the PEI is the second type of PEI.

[0186] In one embodiment, the format of the DCI carrying the first type of PEI is the first DCI format, and the format of the DCI carrying the second type of PEI is the second DCI format. After receiving the DCI carrying the PEI, the terminal determines the first type of PEI and the second type of PEI according to the format of the DCI. Here, the formats of different DCIs can be determined according to whether the DCI carries or does not carry a predetermined information field. In one embodiment, if the DCI carries a predetermined information field, the format of the DCI is determined to be the first DCI format; or, if the DCI does not carry the predetermined information field, the format of the DCI is determined to be the second DCI format.

[0220] In one embodiment, after the terminal reports the capability information of supporting the first type of PEI, the terminal reports the capability information of supporting the second type of PEI. The base station sends the second type of PEI to the terminal. In one embodiment, after the terminal reports the capability information of supporting the first type of PEI, the terminal reports the capability information of supporting the second type of PEI. The base station sends the first type of PEI and the second type of PEI to the terminal. It should be noted that after the terminal receives two different types of PEI, the type of PEI used to perform the paging operation can be determined according to the terminal policy, or it can be a predetermined protocol provision, or it can be a default configuration, which is not limited here. In one embodiment, a terminal that does not support the second type of PEI can also monitor the second type of PEI, that is, ignore the value of the specific sub-paging group, that is, any sub-paging group can wake itself up.

[0221] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0222] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

[0223] Example 1:

[0224] This embodiment provides a group paging method, wherein:

[0225] A scenario on the base station side may be: the base station configures a first type of PEI for the terminal.

[0226] In one embodiment, the first type of PEI and the second type of PEI are not reused; here, the situation of non-reuse may be:

[0227] The first type of PEI may be scrambled using a different PRNTI than the second type of PEI;

[0228] The first type of PEI may use a different common search space than the second type of PEI;

[0229] The first type of PEI may use a different Coreset than the second type of PEI;

[0230] A PEI of the first type may use a different format for the DCI than a PEI of the second type;

[0231] In one embodiment:

[0232] The DCI does not carry the predetermined information, that is, the carried information is empty, indicating that the DCI carries the first type of PEI; in one embodiment, the predetermined information is an information field indicating a sub-paging packet, and not carrying the information means indicating that the DCI indicates the first type of PEI.

[0233] The DCI carries an information bit, and if the bit takes a predetermined value, such as 1, it indicates that the DCI carries the first type of PEI. For ease of understanding, it can be considered that the DCI does not carry an information field indicating a sub-paging packet, that is, only one bit is used, and the value is a predetermined value, indicating that the DCI carries the first type of PEI.

[0234] It should be noted that the base station can configure the first type of PEI and the second type of PEI respectively, indicating the support of the two types of PEI respectively. The base station can also only configure the second type of PEI to implicitly indicate that both PEIs are supported. The base station can also support neither, that is, no PEI of any type is configured.

[0235] In one embodiment, the first type of PEI and the second type of PEI are multiplexed;

[0236] In one embodiment, the first type of PEI and the second type of PEI use the same DCI bearer; that is, there is no need to define different parameters for different types, such as PRNTI, etc.;

[0237] In one embodiment, DCI may carry two types of PEI wake-up information at the same time.

[0238] For example:

[0239] The DCI carries a reserved bit or code point for carrying information of the first type of PEI;

[0240] As an embodiment, a bit or code point value is reserved for the first type of PEI:

[0241] The reserved bit is 0: indicating not to wake up the terminal supporting PEI capability;

[0242] The reserved bit is 1: indicates to wake up the terminal supporting PEI capability;

[0243] The value of this code point is "xxx": indicating not to wake up the terminal supporting PEI capability;

[0244] The code point value is "yyy": indicating waking up a terminal that supports the PEI capability.

[0245] In one embodiment, an identifier is used in the DCI format to indicate whether the PEI is a first type PEI or a second type PEI (the two types cannot coexist in this manner).

[0246] In one embodiment, the system message specifies in advance the type of the PEI format, whether it is the first type of PEI or the second type of PEI.

[0247] In one embodiment, the DCI format does not carry any second type PEI information, that is, the bit of the second type PEI reserved for indicating the sub-paging packet does not exist, and the PEI is regarded as a first type PEI.

[0248] It should be noted that if the base station broadcasts two types of PEI, the base station may support both types of PEI. If the base station broadcasts the second type of PEI, the base station may also support both types of PEI. Of course, if the base station only broadcasts one type, the base station may also only support the corresponding type of PEI.

[0249] In one embodiment, the scenario on the terminal side may be:

[0250] In one embodiment, the terminal reports the capability of supporting the first type of PEI or the capability of supporting the second type of PEI. Here, the terminal may report whether the capability of supporting the second type of PEI is supported after reporting the capability of supporting the first type of PEI. Therefore, the reporting of the first type of PEI depends on the reporting of the second type.

[0251] In one embodiment, the terminal reports the capability of supporting the second type of PEI, which is assumed to be the capability of supporting the first type of PEI. At this time, the base station implicitly determines that the terminal is a terminal capable of supporting two types of PEI.

[0252] In one embodiment, the base station only broadcasts the first type of PEI, and the first type of PEI can be used by the terminal that reports the capability of supporting the second type of PEI or the terminal that reports the capability of supporting the first type of PEI.

[0253] In one embodiment, a terminal supporting the second type of PEI may be considered as a higher-level terminal, which can also support the first type of PEI at the same time.

[0254] In one embodiment, if the base station only broadcasts the second type of PEI:

[0255] In one embodiment, only terminals that have reported the capability to support the second type of PEI can be used;

[0256] In one embodiment, terminals that report the capability of supporting only the first type of PEI may also be used;

[0257] Here, the DCI contains the information of the awakened subgroup. For a terminal that does not support subgroups, any subgroup information can wake up the terminal.
