Description

Information processing method, device and communication system Technical Field

[0001] The embodiments of the present application relate to the field of wireless communication technology. Background Art

[0002] A large number of NR (New Radio) base stations have been deployed in the 3rd Generation Partnership Project (3GPP) standardized mobile communication technology networks. NR base stations require large bandwidths (e.g., 100 MHz), a large number of ports (e.g., 64T / 64R), and shorter time intervals (e.g., 1 ms). NR base stations consume significantly more energy than LTE base stations for functions such as baseband processing and digital front-ends.

[0003] According to operator statistics, the average energy consumption of an NR base station is more than three times that of an LTE base station. Nearly half of the cost of deploying 5G networks by operators is electricity expenses. More importantly, even in periods of no business, the energy consumption of NR base stations is still very high. This is because even when there is no business, NR base stations still need to send public signals, such as Synchronization Signal Block (SSB), System Information Block (SIB, such as SIB1), System Information (SI) and paging, which greatly reduces the energy efficiency of NR base stations. Network energy saving (NES) is an issue that needs to be addressed urgently.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] The inventors discovered that multiple user equipment may coexist in a single cell. For example, UEs that do not support NES technology (referred to as non-NES UEs) and UEs that support NES technology (referred to as NES UEs) may coexist. Non-NES UEs can use traditional paging configuration information and / or methods to determine paging frames (PFs) and / or paging occasions (POs), while NES UEs can use NES-specific paging configuration information and / or methods to determine PFs and / or POs.

[0007] Non-NES UEs and NES UEs may have different PFs and / or POs, but it is currently unclear how to determine the paging frame and / or paging time of the NES UE.

[0008] In order to solve at least one of the above problems or other similar problems, embodiments of the present application provide an information processing method, apparatus, and communication system.

[0009] According to one aspect of an embodiment of the present application, there is provided an information processing apparatus configured in a terminal device, the apparatus comprising:

[0013] A sending unit, which sends first paging configuration information and second paging configuration information to the terminal device.

[0014] According to another aspect of an embodiment of the present application, there is provided an information processing method, applied to a terminal device, the method comprising:

[0019] According to another aspect of an embodiment of the present application, a terminal device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to execute the computer program to implement the above-mentioned information processing method on the terminal device side.

[0020] According to another aspect of an embodiment of the present application, a network device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to execute the computer program to implement the above-mentioned information processing method on the network device side.

[0021] According to another aspect of an embodiment of the present application, a communication system is provided, including:

[0023] A terminal device receives the first paging configuration information and the second paging configuration information, and determines a paging frame and / or a paging time according to the first paging configuration information.

[0024] One of the beneficial effects of the embodiments of the present application is that a terminal device receives first and second paging configuration information sent by a network device, and determines a paging frame and / or paging time based on the first paging configuration information. Thus, when multiple terminal devices coexist, the terminal device can determine the corresponding paging frame and / or paging time based on the corresponding paging configuration information.

[0068] For ease of description, the following description uses a base station as an example of an access network device. In the following description, "if ...", "under ...", and "when ..." can be used interchangeably without causing confusion.

[0069] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0070] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation taking a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101, a terminal device 102, and a terminal device 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0071] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101, the terminal device 102, and the terminal device 103. For example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC), and related communications of terminal devices with reduced capabilities, etc.

[0072] Among them, terminal devices 102 and 103 can be in the RRC_IDLE state, the RRC_INACTIVE state, or the RRC_CONNECTED state. Terminal devices 102 and 103 can also communicate with network device 101. For example, taking terminal device 102 as an example, terminal device 102 can send data to network device 101 or retransmit data. Network device 101 can send a paging message to terminal device 102 or send data to terminal device 102, and terminal device 102 receives data sent by network device 101. In addition, different terminal devices can also communicate with each other. For example, terminal device 102 and terminal device 103 can exchange data.

[0073] It is worth noting that FIG1 shows that terminal device 102 and terminal device 103 are both within the coverage range of network device 101, but the present application is not limited thereto. Terminal device 102 and terminal device 103 may both be outside the coverage range of network device 101, or one of terminal device 102 and terminal device 103 may be within the coverage range of network device 101 and the other may be outside the coverage range of network device 101.

[0074] FIG2 illustrates a deployment scenario of an NES cell according to an embodiment of the present application. As shown in FIG2 , for example, an NES cell is co-deployed with a cell providing coverage, where the cell providing coverage may also be referred to as an anchor cell, and the NES cell may provide network capacity. For another example, an NES cell and a neighboring cell of the NES cell are co-deployed, and the NES cell and the neighboring cell of the NES cell may have completely overlapping coverage areas, partially overlapping coverage areas, or non-overlapping coverage areas. In FIG2 , communication can be performed between the NES cell and the anchor cell, between the NES cell and the neighboring cells of the NES cell, and between the anchor cell and the neighboring cells of the NES cell, for example, via an X2 interface or an F1 interface.

[0075] It is worth noting that FIG2 shows a terminal device in the NES cell, but the present application is not limited to this. The NES cell may also have more than one terminal device (UE). In addition, FIG2 shows that the terminal device is within the coverage of the NES cell, but the present application is not limited to this. The terminal device may also be outside the coverage of the NES cell. In addition, in FIG2, the anchor cell may also be co-deployed with one or more NES cells. An NES cell may have one or more neighboring cells, or may have no neighboring cells.

[0076] Figure 3 illustrates another deployment scenario for an NES cell according to an embodiment of the present application. As shown in Figure 3 , the NES cell is deployed standalone. It is worth noting that while Figure 3 illustrates a single terminal device in the NES cell, the present application is not limited to this. An NES cell may also contain more than one terminal device (UE). Furthermore, Figure 3 illustrates a terminal device within the coverage area of ​​the NES cell, but the present application is not limited to this. A terminal device may also be outside the coverage area of ​​the NES cell.

[0077] Figure 4 is a schematic diagram of the time domain location of existing paging frames and / or paging moments. In a single cell, there are only non-NES UEs, which include, for example, legacy UEs and UEs in Release 19 or subsequent versions that do not support NES technology (such as paging-related technology). The network device only sends paging configuration information for non-NES UEs. For example, the paging configuration information configures a paging cycle (paging DRX cycle) T of 16 radio frames for the non-NES UE, the number of paging frames (paging frames) in a paging cycle (N=T / 4=4), and the number of paging occasions (paging occasions) in a paging frame (Ns=2).

[0078] Assuming that the offset used to determine the paging frame is PF_offset = 0, as shown in Figure 4, there are a total of 4 paging frames in the 16 radio frames of a paging cycle; there is one paging frame in every 4 radio frames, and the first radio frame in every 4 radio frames is a paging frame; each paging frame includes 2 paging moments. As shown in Figure 4, if a paging cycle includes 8 paging moments, the network device needs to send a paging message every 3 radio frames. This frequent waking up to send paging messages at these paging moments will reduce the sleep time of the network device, thereby consuming the network device's power.

[0079] One of the work objectives of 3GPP Release 19 is shown in Table 1 below, namely, to specify the adaptation of common signal or channel transmission, including the adjustment of paging occasions, including limiting the paging occasions in the time domain.

[0080] Table 1

[0081] In a single cell, non-NES UEs and NES UEs may coexist. Non-NES UEs can use traditional paging frame (PF) and paging occasion (PO) calculation methods to determine PF and PO, while NES UEs can use their own specific methods to determine PF and PO.

[0082] Non-NES UEs and NES UEs may have different PFs and / or POs, but it is currently unclear how to determine the paging frame and / or paging time of the NES UE.

[0083] To address at least one of the above problems, embodiments of the present application provide an information processing method, apparatus, and communication system.

[0084] Embodiments of the first aspect

[0085] An embodiment of the present application provides an information processing method, which is described from the perspective of a terminal device.

[0086] FIG5 is a schematic diagram of an information processing method according to an embodiment of the present application, which is applied to a terminal device. As shown in FIG5 , the method includes:

[0087] 501, the terminal device receives first paging configuration information and second paging configuration information sent by the network device; and

[0088] 502. The terminal device determines a paging frame and / or a paging time according to the first paging configuration information.

[0089] It is worth noting that FIG5 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG5 above.

[0090] According to the above embodiment, the terminal device receives the first paging configuration information and the second paging configuration information sent by the network device, and determines the paging frame and / or paging time based on the first paging configuration information. Therefore, when multiple terminal devices coexist, the terminal device can determine the corresponding paging frame and / or paging time based on the corresponding paging configuration information. The method is simple and easy to implement.

[0091] For example, in an NES cell of a network device, non-NES UEs and NES UEs may exist at the same time. Taking an NES UE as an example, the NES UE may receive first paging configuration information and second paging configuration information sent by the network device, where the first paging configuration information is, for example, NES-related paging configuration information (or, also referred to as NES paging configuration information, paging configuration information for NES UEs, or paging configuration information related to NES UEs, or similar names), and the second paging configuration information is, for example, non-NES-related paging configuration information (or, also referred to as non-NES paging configuration information, paging configuration information for non-NES UEs, or paging configuration information related to non-NES UEs, or similar names). The NES UE may ignore, skip, or discard the received non-NES paging configuration information, and determine the paging frame and / or paging time based on the received NES paging configuration information.

[0092] In addition, taking a non-NES UE as an example, the non-NES UE can receive NES paging configuration information and non-NES paging configuration information sent by a network device. The non-NES UE can ignore, skip, or discard the received NES paging configuration information, and determine the paging frame and / or paging time based on the received non-NES paging configuration information.

[0093] Therefore, in the NES cell of the network device, when non-NES UE and NES UE exist at the same time, the non-NES UE and NES UE can each be provided with corresponding paging configurations, thereby, the non-NES UE and NES UE can each determine the paging frame and / or paging time according to the corresponding paging configurations.

[0094] In some embodiments, the terminal device may be a non-NES UE, and accordingly, the first paging configuration information may be non-NES paging configuration information, and the second paging configuration information may be NES paging configuration information. The present application is not limited thereto, and the terminal device may also be an NES UE, and accordingly, the first paging configuration information may be NES paging configuration information, and the second paging configuration information may be non-NES paging configuration information.

[0095] In some embodiments, the terminal device may receive a paging message sent by the network device. For example, the terminal device determines a paging frame and / or a paging time based on the received paging configuration information, and receives a corresponding paging message at the determined paging frame and / or paging time.

[0096] In some embodiments, the paging message may be a Paging message, which is used to find a terminal device in the RRC_IDLE state and the RRC_INACTIVE state to receive data of the called terminal; or the paging message may be a short message, which may be used to notify UEs in the RRC_IDLE state, the RRC_INACTIVE state, and the RRC_CONNECTED state about system information modifications and / or ETWS (Earthquake and Tsunami Warning System) / CMAS (Commercial Mobile Alert System) indications. Both the Paging message and the Short Message are addressed through the P-RNTI (Paging-Radio Network Temporary Identifier) ​​on the PDCCH, but the Paging message is sent on the PCCH, while the Short Message is sent directly through the PDCCH channel.

[0097] In some embodiments, a terminal device in the RRC_IDLE state monitors the PDCCH channel addressed to the P-RNTI to receive core network-initiated paging (CN paging for short), while a terminal device in the RRC_INACTIVE state monitors the PDCCH channel addressed to the P-RNTI to receive RAN-initiated paging (RAN paging for short) and CN paging. In addition, the terminal device monitors the PDCCH channel addressed to the P-RNTI to receive Short Messages. The terminal device does not need to monitor the paging channel continuously; it only needs to monitor the paging channel at one paging moment in a paging cycle.

[0098] In some embodiments, a terminal device in the RRC_CONNECTED state monitors the PDCCH channel addressed to the P-RNTI at least once at any paging time in each modification period to receive a Short Message indicating system information modification and / or ETWS, if the terminal device is provided with a common search space for monitoring paging on the active bandwidth part (active BWP).

[0099] In the following, the method of the embodiment of the present application is exemplarily described by taking the terminal device as an NES UE, the first paging configuration information as NES paging configuration information, and the second paging configuration information as non-NES paging configuration information as an example.

[0100] In order to save energy on network devices, it is desirable that paging frames and / or paging occasions be concentrated in time or limited to a time window (or time range) as much as possible. In this way, network devices do not need to wake up frequently due to sending paging messages and can sleep between adjacent paging occasions to save power.

[0101] In some embodiments, for non-NES UEs in a cell, the PFs and / or POs of the non-NES UEs may be configured by the network device to be more sparse, for example, by increasing the interval between adjacent PFs and / or adjacent POs in the time domain. For example, at least one of increasing the paging DRX cycle (T), reducing the number of paging frames within a paging cycle, or reducing the number of paging moments within a paging frame may be employed.

[0102] In some embodiments, the second paging configuration information may include at least one paging parameter. For example, the second paging configuration information may include at least one of the following: a paging cycle, a radio frame offset, the number of paging frames in a paging cycle, or the number of paging moments in a paging frame. The present application is not limited thereto, and the second paging configuration may also include other content. Compared with the case where there are only non-NES UEs in the cell, the paging cycle of the second paging configuration information may be larger, and / or the number of paging frames in a paging cycle may be smaller, and / or the number of paging moments in a paging frame may be smaller, and so on.

[0103] In some embodiments, the non-NES UE may determine the paging frame and / or the paging time according to the second paging configuration information in various ways.

[0104] For example, a non-NES UE may determine a corresponding paging frame according to the UE identifier, the paging cycle, the radio frame offset, and the number of paging frames in a paging cycle.

[0105] For example, the system frame number (SFN) of the PF can be determined by the following formula:

[0106] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0107] Wherein, T is the DRX cycle (DRX cycle) of the non-NES UE, that is, the paging cycle, N is the total number of paging frames in T, PF_offset is the radio frame offset used to determine PF, and UE_ID is the identifier of the UE.

[0108] For another example, a non-NES UE may determine the paging time according to the UE identifier and the number of paging times in a paging frame.

[0109] For example, the index indicating the PO can be determined by the following formula:

[0110] i_s=floor(UE_ID / N)mod Ns

[0111] Wherein, i_s is the index indicating the PO, UE_ID is the identifier of the UE, N is the total number of paging frames in the paging cycle, and Ns is the number of paging occasions of a PF.

[0112] Among them, UE_ID can be in the following form: if the UE works in eDRX mode, UE_ID is 5G-S-TMSI mod 4096; otherwise, UE_ID is 5G-S-TMSI mod 1024, wherein the value of 5G-S-TMSI (5G-S-Temporary Mobile Subscription Identifier) ​​can refer to the relevant technology and will not be explained here. This application is not limited to this, and UE_ID may also be in other forms.

[0113] After determining the system frame number and paging time index of the paging frame, the non-NES UE can receive the paging message in the symbol or time slot corresponding to the index in the radio frame corresponding to the system frame number. The correspondence between the paging time index and the symbol or time slot can be found in related art and will not be further explained here.

[0114] For NES UEs in a cell, the PF and / or PO of the NES UE can be set at a time domain position with a preset offset relative to the PF and / or PO of non-NES UEs. This allows the PF and / or PO of non-NES and NES UEs to be as close together as possible or confined to a time window. This reduces the need for network devices to frequently send paging messages and allows them to sleep between adjacent paging occasions to save power.

[0115] The following is an exemplary description of the first paging configuration information of the NES UE.

[0116] In some embodiments, the number of the first paging configuration information may be one or more than one.

[0117] In some embodiments, a first paging configuration information may correspond to a type of network energy conservation level. For example, a NES cell of a network device may correspond to multiple network energy conservation levels (e.g., high, medium, low, etc.). Different first paging configuration information is configured for different network energy conservation levels, thereby enabling more flexible and dynamic implementation of different levels of network energy conservation.

[0118] In some embodiments, a first paging configuration information may correspond to a group of terminal devices or a set of terminal devices. For example, NES UEs may be divided into multiple groups or multiple sets (NES UE groups or NES UE sets may also be referred to as paging groups or paging sets). Different first paging configuration information is configured for different groups or sets. Thus, even when there are a large number of NES UEs, sufficient paging resources can be allocated to the NES UEs, ensuring that the NES UEs can reliably receive paging messages.

[0119] Take the first paging configuration information as an example:

[0120] In some embodiments, the first paging configuration information may include at least one or a group of paging parameters. For example, the first paging configuration information may be used to configure a paging frame offset and / or a paging time offset.

[0121] In some embodiments, the paging frame offset may include a first offset (NES_PF_offset1), wherein the paging frame may be determined according to the first offset and the initial offset (PF_offset).

[0122] The initial offset (PF_offset) may be a radio frame offset used to determine a paging frame. For example, the initial offset may be a radio frame offset used to determine a paging frame for a non-NES UE in the same NES cell as the NES UE.

[0123] The first offset may be a radio frame superimposed offset used to determine a paging frame of an NES UE (also referred to as an NES paging-related paging frame). For example, the first offset may be a radio frame offset superimposed on an initial offset.

[0124] In some embodiments, the system frame number of the paging frame of the NES UE is determined by:

[0125] (SFN+PF_offset+NES_PF_offset1)mod T=(T div N)*(UE_ID mod N)

[0126] Among them, SFN is the system frame number of the paging frame of the NES UE, PF_offset is the initial offset, NES_PF_offset1 is the first offset, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0127] In some embodiments, the first paging configuration information may further include at least one of a paging cycle T, an initial offset PF_offset, and a number N of paging frames in a paging cycle. The paging cycle T, the initial offset PF_offset, and the number N of paging frames in a paging cycle in the first paging configuration information may be the same as or different from the paging cycle T, the initial offset PF_offset, and the number N of paging frames in a paging cycle in the second paging configuration information.

[0128] However, the present application is not limited thereto, and the first paging configuration information may not include the paging cycle T, the initial offset PF_offset, and the number of paging frames in a paging cycle N. In this case, the NES UE and the non-NES UE may share at least one of the paging cycle T, the initial offset PF_offset, and the number of paging frames in a paging cycle N in the second paging configuration information.

[0129] In some embodiments, the first offset may be network configured or predefined, and the value of the first offset may be 0, a positive integer, or a negative integer.

[0130] For example, if the paging cycle T, initial offset PF_offset, and number of paging frames N in a paging cycle of a non-NES UE are the same as those of an NES UE, then for the non-NES UE and NES UE with the same value of UE_ID mod N:

[0131] When the first offset is 0, the paging frames of the non-NES UE and the NES UE have the same system frame number. This allows paging messages for both the non-NES UE and the NES UE to be sent in a single radio frame, concentrating paging frames in time and allowing network devices to sleep longer, thus avoiding frequent wake-ups and further saving network energy.

[0132] When the value of the first offset is not 0, the system frame numbers of the paging frames of the non-NES UE and the NES UE are different. For example, when the value of the first offset is 1, the paging frame of the NES UE is a radio frame adjacent to the paging frame of the non-NES UE in the time domain. As a result, the paging messages of the non-NES UE and the NES UE can be sent in two adjacent radio frames, which can concentrate the paging frames within a certain time range, extend the sleep time of the network equipment, avoid frequent waking up of the network equipment, and thus further save network energy consumption. In addition, sending the paging messages of the non-NES UE and the NES UE respectively in two radio frames facilitates the non-NES UE and the NES UE to reliably receive the corresponding paging messages.

[0133] In some embodiments, the sum of the first offset and the initial offset is less than T divided by N.

[0134] In some embodiments, the paging frame offset may include a second offset (NES_PF_offset2), wherein the paging frame may be determined according to the second offset.

[0135] The second offset may be a radio frame offset used to determine a paging frame of an NES UE (also referred to as an NES paging-related paging frame).

[0136] In some embodiments, the system frame number of the paging frame of the NES UE is determined by:

[0137] (SFN+NES_PF_offset2)mod T=(T div N)*(UE_ID mod N)

[0138] Among them, SFN is the system frame number of the paging frame of the NES UE, NES_PF_offset2 is the second offset, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0139] In some embodiments, the second offset may be different from the initial offset, thereby enabling the paging frame of the NES UE to be set in a radio frame different from the paging frame of the non-NES UE. The present application is not limited thereto, and the second offset may also be the same as the initial offset, thereby enabling the paging frame of the NES UE and the paging frame of the non-NES UE to be set in the same radio frame.

[0140] In some embodiments, the second offset may be network configured or predefined, and the value of the second offset may be 0, a positive integer, or a negative integer.

[0141] In some embodiments, the difference between the second offset and the initial offset may be 0, a positive integer, or a negative integer. For example, the difference between the second offset and the initial offset may be 1.

[0142] In some embodiments, the value of the second offset is less than T divided by N.

[0143] In some embodiments, when the paging frame offset (e.g., the first offset and / or the second offset) is not configured, the system frame number of the paging frame of the NES UE can be determined in a manner similar to or the same as that of the non-NES UE:

[0144] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0145] Among them, SFN is the system frame number of the paging frame, PF_offset is the initial offset, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0146] In some embodiments, the paging time of the NES UE may be determined based on the paging time offset and the index of the paging time.

[0147] In some embodiments, the paging time of the NES UE may be the sum of the time slot number or symbol number corresponding to the index and the paging time offset. That is, the time domain position of the paging time of the NES UE may be: the time domain position of the paging time indicated by the paging time index plus the time domain position of the paging time offset.

[0148] The index of the paging time of the NES UE may be determined in a manner similar to or identical to that of the non-NES UE. For example, the index of the paging time of the NES UE may be determined in the following manner:

[0149] i_s=floor(UE_ID / N)mod Ns

[0150] Among them, i_s is the index of the paging time, UE_ID is the terminal equipment identifier, N is the number of paging frames in the paging cycle, and Ns is the number of paging times in a paging frame.

[0151] In some implementations, the first paging configuration information may further include at least one of the number N of paging frames in a paging cycle or the number Ns of paging moments in a paging frame. The number N of paging frames in a paging cycle or the number Ns of paging moments in a paging frame in the first paging configuration information may be the same as or different from the number N of paging frames in a paging cycle or the number Ns of paging moments in a paging frame in the second paging configuration information.

[0152] However, the present application is not limited thereto, and the first paging configuration information may not include the number N of paging frames in a paging cycle and the number Ns of paging moments in a paging frame. In this case, the NES UE and the non-NES UE may share the number N of paging frames in a paging cycle and the number Ns of paging moments in a paging frame in the second paging configuration information.

[0153] For example, if the number of paging frames (N) and the number of paging moments (Ns) in a paging cycle of a non-NES UE are the same as the number of paging frames (N) and the number of paging moments (Ns) in a paging frame of an NES UE, then for a non-NES UE and an NES UE with the same value of UE_ID mod N, the paging moment index of the non-NES UE is the same as the paging moment index of the NES UE, and the symbol number or time slot number of the paging moment of the NES UE is equal to the symbol number or time slot number corresponding to the paging moment index of the non-NES UE + the paging moment offset. In some embodiments, the paging moment offset can be network-configured or predefined, and the value of the paging moment offset can be 0, a positive integer, or a negative integer. For example, when the paging moment offset is 1, the paging moment of the NES UE is located in a symbol or time slot adjacent to the paging moment of the non-NES UE in the time domain.

[0154] In some embodiments, when the paging time offset is not configured, the paging time may be determined based on the paging time index. For example, the time domain position of the paging time of the NES UE is the symbol or time slot corresponding to the index.

[0155] In some embodiments, the system frame number of the paging frame of the NES UE may be the same as or different from the system frame number of the paging frame of the non-NES UE; the index of the paging time of the NES UE may be the same as or different from the index of the paging time of the non-NES UE.

[0156] The following is an exemplary description of the time domain positions of the paging frames and paging moments of non-NES UE and NES UE.

[0157] FIG6 is a schematic diagram of the time domain positions of the paging frames and paging times of the non-NES UE and the NES UE according to an embodiment of the present application.

[0158] For example, the second paging configuration information configures a paging cycle of 16 radio frames for the non-NES UE, where N=T / 8=2, Ns=2, and PF_offset=0.

[0159] As shown in FIG6 , among the 16 radio frames in a paging cycle, the first and ninth radio frames (eg, radio frames with SFN=0 and SFN=8) are paging frames for non-NES UEs, and each paging frame includes two paging times.

[0160] In the first paging configuration information of the NES UE, if NES_PF_offset1=1 or NES_PF_offset2=1 is used and NES_PO_offset is not configured or indicated, the PF and / or PO are as follows:

[0161] As shown in FIG6 , among the 16 radio frames in a paging cycle, there are two paging frames for NES UEs, namely, the second and tenth radio frames (e.g., radio frames with SFN=1 and SFN=9) are paging frames for NES UEs; each paging frame includes two paging moments.

[0162] As shown in Figure 6, network devices can send paging messages every six radio frames. Compared to the time domain positions shown in Figure 4, the number of POs within a paging cycle remains unchanged, but the interval between paging messages sent by network devices has increased from three radio frames to six. This allows network devices to sleep longer, avoid frequent wake-ups, and further save network energy.

[0163] FIG7 is another schematic diagram of the time domain positions of the paging frames and paging moments of the non-NES UE and the NES UE according to an embodiment of the present application.

[0164] For example, the second paging configuration information configures a paging cycle of 16 radio frames for the non-NES UE, where N=T / 8=2, Ns=2, and PF_offset=0.

[0165] In the first paging configuration information of the NES UE, NES_PF_offset1 or NES_PF_offset2 is not configured or indicated, and NES_PO_offset is configured. Then, PF and / or PO are as follows:

[0166] As shown in Figure 7, of the 16 radio frames in a paging cycle, two paging frames are shared by both non-NES UEs and NES UEs. These frames are the first and ninth (e.g., radio frames with SFN = 0 and SFN = 8) paging frames for both non-NES and NES UEs. Each paging frame includes four paging times. Of these four paging times, two are for non-NES UEs, and the remaining two are for NES UEs.

[0167] As shown in Figure 7, network devices can send paging messages every seven radio frames. Compared to the time domain positions shown in Figure 4, the number of POs within a paging cycle remains unchanged, but the interval between paging messages sent by network devices has increased from three radio frames to seven. This allows network devices to sleep longer, avoid frequent wake-ups, and further save network energy.

[0168] Take the case where there is more than one first paging configuration information as an example:

[0169] NES UEs may be divided into more than one group or configured / indicated with more than one first paging configuration information. An NES UE may determine its PF and / or PO using its corresponding / related paging configuration parameters.

[0170] The following describes an exemplary method for determining a PF and / or a PO by an NES UE, taking the i-th first paging configuration information as the first paging configuration information corresponding to / related to the NES UE as an example. The i-th first paging configuration information may be the i-th first paging configuration information configured or activated for the NES UE.

[0171] In some embodiments, the i-th first paging configuration information may be used to configure paging frame offset_i and / or paging time offset_i, where 1≤i≤K, and K is the number of first paging configuration information.

[0172] It should be noted that i here represents the i-th, and its value range is 1≤i≤K. If the index or identifier of the first paging configuration information starts from 1, then i=index or identifier; if the index or identifier of the first paging configuration information starts from 0, then i-1=index or identifier.

[0173] In some embodiments, the paging frame offset_i may include a first offset_i (NES_PF_offset1_i), wherein the paging frame may be determined according to the first offset_i and the initial offset (PF_offset).

[0174] The first offset_i is similar to the aforementioned first offset and may be a radio frame superimposed offset used to determine the paging frame of the NES UE (also known as the NES paging-related paging frame). For example, the first offset_i may be a radio frame offset superimposed on the initial offset.

[0175] In some embodiments, the system frame number of the paging frame of the NES UE is determined by:

[0176] (SFN+PF_offset+NES_PF_offset1_i)mod T=(T div N)*(UE_ID mod N)

[0177] Among them, SFN is the system frame number of the paging frame, PF_offset is the initial offset, NES_PF_offset1_i is the first offset_i, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0178] In some embodiments, the first offset_i (NES_PF_offset1_i) may be directly configured in the i-th first paging configuration information.

[0179] However, the present application is not limited thereto. For example, in some embodiments, the difference between firstOffset_i and firstOffset_i-1 may be fixed. For example, the difference between firstOffset_i and firstOffset_i-1 may be X, where 2≤i≤K. Thus, by configuring the difference X in the first paging configuration information, the firstOffset_i of the i-th first paging configuration information can be determined.

[0180] In some embodiments, the first offset_i may be X, where i=1.

[0181] In this case, the first offset_i=i*X. The system frame number of the paging frame of the NES UE is determined by:

[0182] (SFN+PF_offset+i*X)mod T=(T div N)*(UE_ID mod N)

[0183] Among them, SFN is the system frame number of the paging frame, PF_offset is the initial offset, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0184] In some embodiments, the number K of first paging configuration information may be network configured or predefined, or may be derived based on the number of paging configurations, for example, configured via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or an anchor cell (or a neighboring cell of an NES cell).

[0185] In some embodiments, the first offset_i may be network-configured or predefined, for example, via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or anchor cell (or a neighboring cell of the NES cell). The value of the first offset_i may be 0, a positive integer, or a negative integer.

[0186] In some embodiments, X may be network-configured or predefined. For example, it may be configured via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or anchor cell (or a neighboring cell of the NES cell). The value of X may be 0, a positive integer, or a negative integer. For example, X=1.

[0187] In some embodiments, the paging frame offset_i may include a second offset_i (NES_PF_offset2_i), wherein the paging frame may be determined according to the second offset_i.

[0188] In some embodiments, the system frame number of the paging frame of the NES UE is determined by:

[0189] (SFN+NES_PF_offset2_i)mod T=(T div N)*(UE_ID mod N)

[0190] Among them, SFN is the system frame number of the paging frame, NES_PF_offset2_i is the second offset_i, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0191] In some embodiments, the second offset_i may be the same as or different from the aforementioned initial offset.

[0192] In some embodiments, the second offset_i (NES_PF_offset2_i) may be directly configured in the i-th first paging configuration information.

[0193] However, the present application is not limited thereto. For example, in some embodiments, the difference between secondOffset_i and secondOffset_i-1 may be fixed. For example, the difference between secondOffset_i and secondOffset_i-1 may be Y, where 2≤i≤K. Thus, by configuring the difference Y in the first paging configuration information, the secondOffset_i of the i-th first paging configuration information can be determined.

[0194] In some embodiments, the second offset_i may be Y, where i=1.

[0195] In this case, the second offset_i=i*Y. The system frame number of the paging frame of the NES UE is determined by:

[0196] (SFN+i*Y)mod T=(T div N)*(UE_ID mod N)

[0197] Among them, SFN is the system frame number of the paging frame, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0198] In some embodiments, the second offset_i may be network-configured or predefined, for example, via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or anchor cell (or a neighboring cell of the NES cell). The value of the second offset_i may be 0, a positive integer, or a negative integer.

[0199] In some embodiments, Y may be network-configured or predefined. For example, it may be configured via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or anchor cell (or a neighboring cell of the NES cell). The value of Y may be 0, a positive integer, or a negative integer. For example, Y = 1.

[0200] In some embodiments, when the paging frame offset_i is not configured, the system frame number of the paging frame of the NES UE can be determined in a similar or identical manner to that of the non-NES UE:

[0201] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0202] Among them, SFN is the system frame number of the paging frame, PF_offset is the initial offset, T is the paging cycle, N is the number of paging frames in the paging cycle, and UE_ID is the terminal equipment identifier.

[0203] In some embodiments, the paging time of the NES UE may be determined based on the paging time offset_i and the index of the paging time.

[0204] In some embodiments, the paging time of the NES UE may be the sum of the time slot number or symbol number corresponding to the index and the paging time offset_i. That is, the time domain position of the paging time of the NES UE may be the time domain position of the paging time indicated by the paging time index plus the time domain position of the paging time offset_i.

[0205] The index of the paging time of the NES UE may be determined in a manner similar to or identical to that of the non-NES UE. For example, the index of the paging time of the NES UE may be determined in the following manner:

[0206] i_s=floor(UE_ID / N)mod Ns

[0207] Among them, i_s is the index of the paging time, UE_ID is the terminal equipment identifier, N is the number of paging frames in the paging cycle, and Ns is the number of paging times in a paging frame.

[0208] In some embodiments, the paging time offset_i may be directly configured in the i-th first paging configuration information.

[0209] However, the present application is not limited thereto. For example, in some embodiments, the difference between paging time offset_i and paging time offset_i-1 may be fixed. For example, the difference between paging time offset_i and paging time offset_i-1 may be Z, where 2≤i≤K. Thus, by configuring the difference Z in the first paging configuration information, the paging time offset_i of the i-th first paging configuration information can be determined.

[0210] In some embodiments, paging time offset_i may be Z, where i = 1. In this case, paging time offset_i = i*Z.

[0211] In some embodiments, paging time offset_i may be network-configured or predefined, for example, via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or anchor cell (or a neighboring cell of an NES cell). The value of paging time offset_i may be 0, a positive integer, or a negative integer.

[0212] In some embodiments, Z may be network-configured or predefined. For example, it may be configured via SIB1 or other SIBs or RRC messages (e.g., RRC reconfiguration or RRC release messages) of an NES cell or anchor cell (or a neighboring cell of an NES cell). The value of Z may be 0, a positive integer, or a negative integer. For example, Z = 1.

[0213] The following is an exemplary description of the time domain positions of the paging frames and paging moments of non-NES UE and NES UE.

[0214] FIG8 is another schematic diagram of the time domain positions of the paging frames and paging moments of the non-NES UE and the NES UE according to an embodiment of the present application.

[0215] For example, if there are three groups of NES UEs, the network device configures three first paging configurations, i.e., K = 3. Furthermore, each group of NES UEs is configured with one first paging configuration. N can be configured as T / 16 to ensure that the total number of POs within T remains unchanged (i.e., the total amount of paging resources in the cell remains unchanged). The paging DRX cycle is 16 radio frames, Ns = 2, and PF_offset = 0.

[0216] The first offsets in adjacent first paging configuration information differ by 1, and the first offset_1 in the first first paging configuration information is 1.

[0217] As shown in FIG8 , in the 16 radio frames of a paging cycle, the first radio frame (eg, the radio frame with SFN=0) is a paging frame for non-NES UEs, and each paging frame includes two paging times.

[0218] The second radio frame (for example, a radio frame with SFN=1) is a paging frame for the first group of NES UEs, and each paging frame includes two paging times; the third radio frame (for example, a radio frame with SFN=2) is a paging frame for the second group of NES UEs, and each paging frame includes two paging times; the fourth radio frame (for example, a radio frame with SFN=3) is a paging frame for the third group of NES UEs, and each paging frame includes two paging times.

[0219] As shown in Figure 8, within a paging cycle, a network device can send paging messages in four consecutive radio frames and remain in sleep mode during the remaining 12 radio frames. Compared to the time domain positions shown in Figure 4, the number of POs within a paging cycle remains unchanged, but the interval between paging messages sent by the network device has increased from three radio frames to 12. This allows the network device to sleep longer, avoid frequent wake-ups, and further save network energy.

[0220] FIG9 is another schematic diagram of the time domain positions of the paging frames and paging moments of the non-NES UE and the NES UE according to an embodiment of the present application.

[0221] The paging time offsets in adjacent first paging configuration information differ by 1, and the paging time offset_1 in the first first paging configuration information is 1.

[0222] As shown in FIG9 , in the 16 radio frames of a paging cycle, the first radio frame is the paging frame for non-NES UE, the first group of NES UE, the second group of NES UE, and the third group of NES UE.

[0223] The paging frame includes 2 groups of 8 paging times. In one group of paging times, the paging times of non-NES UEs, the paging times of the first group of NES UEs, the paging times of the second group of NES UEs, and the paging times of the third group of NES UEs are arranged in chronological order.

[0224] As shown in Figure 9, within a paging cycle, a network device can send a paging message in one radio frame and remain in sleep mode for the remaining 15 radio frames. Compared to the time domain positions shown in Figure 4, the number of POs within a paging cycle remains unchanged, but the interval between paging messages sent by the network device has increased from three radio frames to 15. This allows the network device to sleep longer, avoid frequent wake-ups, and further save network energy.

[0225] In some embodiments, when there are multiple first paging configuration information, the terminal device can determine the first paging configuration information related / corresponding thereto in various ways.

[0226] For example, the terminal device may determine the corresponding first paging configuration information according to the terminal device identifier, and thus may determine the paging frame and / or paging time according to the corresponding first paging configuration information.

The present application is not limited to this, and the corresponding first paging configuration information can also be determined according to the terminal device identifier in other ways.

[0228] If the UE operates in eDRX mode, the UE_ID is 5G-S-TMSI mod 4096; otherwise, the UE_ID is 5G-S-TMSI mod 1024. If the UE does not yet have a 5G-S-TMSI, the UE_ID may be set to 0.

For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced.

[0231] For another example, the terminal device may determine the corresponding first paging configuration information based on the identifier or index of the terminal device group or terminal device set to which the terminal device is located, thereby determining the paging frame and / or paging time based on the corresponding first paging configuration information.

[0232] The identifier or index may be configured by a network device, for example, by a core network or an access network, or may be predefined.

Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG11 above.

[0235] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0236] According to the above embodiment, the terminal device receives the first paging configuration information and the second paging configuration information sent by the network device, and determines the paging frame and / or paging time based on the first paging configuration information.
