The communication equipment may also include other equipment in the communication system, such as network controllers, mobile management entities and other network entities, which are not limited to the embodiments of the present application.

[0052] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0053] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0054] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0055] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0056] Exemplarily, paging includes a physical downlink control channel (PDCCH) scrambled by a paging-radio network temporary identifier (P-RNTI) and a physical downlink shared channel (PDSCH) scheduled by the PDCCH. The paging message is transmitted in the PDSCH, and the short message is 8 bits in the PDCCH.

[0057] For UEs in RRC IDLE or RRC INACTIVE states, since there is no other data communication between the UE and the network, in order to save power on the terminal, the UE can monitor the paging channel discontinuously, that is, adopt the paging discontinuous reception (DRX) mechanism. Under the paging DRX mechanism, the UE only needs to monitor paging during one paging occasion (Paging Occasion, PO) in each DRX (cycle). PO includes a series of PDCCH monitoring opportunities, which can be composed of multiple time slots. In addition, a paging frame (Paging Frame, PF) is a radio frame (for example, fixed 10ms), which can contain multiple POs or the starting positions of multiple POs.

[0058] The paging DRX cycle is determined by the common cycle in the system broadcast and the dedicated cycle configured in the high-level signaling (such as the non-access stratum (NAS) signaling). The UE can take the minimum cycle of the two as the paging cycle. On the network side, a paging DRX cycle can have multiple POs, and the position where the UE monitors the PO is related to the ID of the UE. For example, the PF and PO of a UE in a paging DRX cycle are determined as follows:

[0059] The SFN (System Frame Number) of the PF can be determined by the following formula:

[0060] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0061] The index (i_s) of a PO in a PF is determined by the following formula:

[0062] i_s=floor(UE_ID / N)mod Ns

[0063] The parameters in the above formula are explained as follows:

[0064] T: The DRX cycle of the UE receiving paging. The network will broadcast a default DRX cycle. If the RRC / higher layer configures a UE-specific DRX cycle for the UE, the minimum of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC / higher layer will be used as the DRX cycle of the UE. If the RRC / higher layer does not configure a UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network will be used as the DRX cycle of the UE.

[0065] N: the number of PFs included in a DRX cycle.

[0066] Ns: The number of POs contained in a PF.

[0067] PF_offset: A time domain offset used to determine PF.

[0068] UE_ID: UE identifier, for example 5G-S-TMSI mod 1024.

[0069] In addition, mod represents the modulo operation, div represents the integer division operation, and floor() represents rounding down.

[0070] In a project to further enhance end-use energy efficiency, a goal could include:

[0071] Specify enhancements for idle / inactive-mode UE power saving, considering system performance aspects. For example [RAN2, RAN1].

[0072] Study and specify paging enhancement(s) to reduce unnecessary UE paging receptions, subject to no impact to legacy UEs. For example [RAN2, RAN1].

[0073] NOTE: RAN1 to check and update, if needed, evaluation methodology in RAN1#100 meeting.

[0074] Specify means to provide potential TRS / CSI-RS occasion(s)available in connected mode to idle / inactive-mode UEs,minimizing system overhead impact. Such as [RAN1].

[0075] NOTE: Always-on TRS / CSI-RS transmission by gNodeB is not required.

[0076] That is, by designing an enhanced paging mechanism, unnecessary UE paging reception is reduced.

[0077] The reception of PO includes blind detection of PDCCH and the corresponding PDSCH. The network indicates the time-frequency resource location of the corresponding PDSCH through PDCCH, where the time slot where the PDSCH is located is determined by the time slot offset k0 of the PDSCH relative to the PDCCH. For example, the value range of k0 can be 0 to 32 time slots.

[0078] For non-connected UEs, the UE also needs to use the synchronization signal (SS) burst to perform synchronization operations before blindly detecting PDCCH. PDCCH has low requirements for synchronization accuracy, and the UE may need fewer SSbursts to complete PDCCH synchronization. However, PDSCH has high requirements for synchronization accuracy. For UEs with good channel quality, such as those with high signal to interference noise ratio (SINR), fewer SSbursts may be needed to complete PDSCH synchronization; for UEs with poor channel quality, such as those with low SINR, more SS bursts may be needed to complete PDSCH synchronization. The SS burst period is configured by the network. For example, the SS burst period can include 5ms, 10ms, 20ms, 40ms, 80ms and 160ms. If the SS burst period is greater than the time interval between PDSCH and PDCCH, the UE needs to complete the synchronization for PDSCH before blindly detecting PDCCH. In other words, a UE in deep sleep state needs to wake up and start synchronization operations multiple SS burst periods before PO. If the UE detects the PDCCH on its corresponding PO, the UE continues to receive the PDSCH based on the PDCCH indication. If the UE does not detect the PDCCH on its corresponding PO, the UE stops receiving the PDSCH and returns to the deep sleep state.

[0079] For the second case, since the UE does not need to receive PDSCH, it is not necessary for the UE to wake up and start synchronization multiple SS burst cycles before PO. How to reduce unnecessary synchronization time of the UE and save UE power consumption is a problem that needs to be solved.

[0080] Figure 2 is a schematic flow chart of a paging method 200 according to an embodiment of the present application. The method may optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0081] S210. The terminal device receives a time domain resource allocation indication.

[0082] S220. The terminal device determines the time domain resource allocation information corresponding to the paging message based on the time domain resource allocation indication, the first information and the terminal type.

[0083] Exemplarily, the terminal device may receive the first information semi-statically configured by the network device. If the terminal device receives the time domain resource allocation indication dynamically sent by the network device, the time domain resource allocation information corresponding to the paging message may be determined based on the time domain resource allocation indication, the configured first information and the terminal type.

[0084] Optionally, the first information includes at least one of the following:

[0085] Time domain resource allocation list;

[0086] Relative offset of time domain resources.

[0087] Exemplarily, a plurality of terminal types may be divided, and different time domain resource allocation information may be determined based on different terminal types.

[0088] Optionally, the terminal type is a first-category terminal or a second-category terminal.

[0089] Exemplarily, the terminal type may also include more than two types. In addition, the first type of terminal and / or the second type of terminal may also be further subdivided into multiple subtypes.

[0090] Optionally, the terminal type is determined based on at least one of the following:

[0091] Whether cross-carrier scheduling is supported;

[0092] The power saving requirements of the terminal equipment.

[0093] Optionally, the terminal type is determined based on at least one of the following:

[0094] Terminal devices that support cross-carrier scheduling are classified as first-category terminals, and terminal devices that do not support cross-carrier scheduling are classified as second-category terminals;

[0095] Power-saving terminals are first-class terminals, and non-power-saving terminals are second-class terminals;

[0096] The power-saving terminals that support cross-carrier scheduling are the first type of terminals, otherwise they are the second type of terminals.

[0097] Optionally, in the case where the terminal type is determined based on whether cross-carrier scheduling is supported, the terminal device may inform the network device whether it supports cross-time slot scheduling through a capability report.

[0098] Optionally, in the case where the terminal type is determined based on the power saving requirement, a terminal device with a power saving requirement may be called a power saving terminal, and a terminal device without a power saving requirement may be called a non-power saving terminal. In this case, the paging method may further include:

[0099] During the initial attachment process, the terminal device reports to the Access and Mobility Management Function (AMF) whether the terminal device is a power-saving terminal.

[0100] Optionally, when the terminal type is determined based on the power saving requirement, the reporting method includes at least one of the following:

[0101] Reporting whether the terminal device is a power-saving terminal based on whether the registration request message carries a power-saving terminal indication field;

[0102] Report whether the terminal device is a power-saving terminal based on the value of the power-saving terminal indication field carried in the registration request message.

[0103] For example, if the registration request message carries a power-saving terminal indication field, reporting the registration request information may indicate that the terminal device is a power-saving terminal. If the registration request message does not carry a power-saving terminal indication field, reporting the registration request information may indicate that the terminal device is a non-power-saving terminal.

[0104] For another example, if the value of the power-saving terminal indication field carried in the registration request message is the first value, reporting the registration request information can indicate that the terminal device is a power-saving terminal. If the value of the power-saving terminal indication field carried in the registration request message is the second value, reporting the registration request information can indicate that the terminal device is a non-power-saving terminal. The first value and the second value are different.

[0105] Optionally, in the case where the terminal type is determined based on whether cross-carrier scheduling is supported and power saving requirements, if the power saving terminal supporting cross-carrier scheduling is a first type of terminal, the second type of terminal may include a power saving terminal that does not support cross-carrier scheduling, a non-power saving terminal that supports cross-carrier scheduling, and a non-power saving terminal that does not support cross-carrier scheduling. Optionally, the terminal device may inform the network whether the terminal device supports cross-time slot scheduling through a capability report.

[0106] In an embodiment of the present application, a terminal device may be configured in a variety of ways so that the terminal device can determine the time domain resource allocation information corresponding to the paging message based on its own terminal type. For example, in method one, different PDSCH time domain resource allocation lists may be configured for different types of terminals. For another example, in method two, the time domain resource relative offset may be configured so that the terminal can calculate different time domain resource offsets. In addition, in an embodiment of the present application, for the sake of simplicity, the PDCCH used to indicate paging may be referred to as PDCCH, and the PDSCH corresponding to the paging message may be referred to as PDSCH.

[0107] Optionally, in mode 1, different terminal types correspond to different physical downlink shared channel PDSCH time domain resource allocation lists. For example, the first type of terminal and the second type of terminal correspond to different PDSCH time domain resource allocation lists.

[0108] Optionally, in method 1, the paging method further includes: the terminal device receives a first PDSCH time domain resource allocation list configured by the network device for the first type of terminals.

[0109] Optionally, in method 1, the paging method further includes: the terminal device receives a second PDSCH time domain resource allocation list configured by the network device for the second type of terminals.

[0110] Exemplarily, the network device may send the time domain resource allocation list by broadcasting. If the terminal device does not receive the second PDSCH time domain resource allocation list, it means that the network device does not have the second PDSCH time domain resource allocation list configured for the second type of terminal, and the terminal device may use the default PDSCH time domain resource allocation list.

[0111] Optionally, in method one, the terminal device determines the time domain resource allocation information corresponding to the paging message based on the time domain resource allocation indication, the first information and the terminal type, including: the terminal device determines the PDSCH time domain resource allocation information corresponding to the paging message based on the time domain resource allocation indication, the PDSCH time domain resource allocation list and the terminal type.

[0112] Optionally, the terminal device determines, based on the time domain resource allocation indication, the PDSCH time domain resource allocation list and the terminal type, PDSCH time domain resource allocation information corresponding to the paging message, including at least one of the following:

[0113] When the terminal device is a first type of terminal, determine the PDSCH time domain resource allocation information corresponding to the paging message according to the time domain resource allocation indication in the physical downlink control channel PDCCH used to indicate paging and the first PDSCH time domain resource allocation list, wherein the PDSCH time domain resource allocation information includes the first time domain resource offset;

[0114] When the terminal device is a second type of terminal and there is a second PDSCH time domain resource allocation list configured by the network device, the PDSCH time domain resource allocation information corresponding to the paging message is determined according to the time domain resource allocation indication in the PDCCH and the second PDSCH time domain resource allocation list;

[0115] When the terminal device is a second type of terminal and there is no second PDSCH time domain resource allocation list configured by the network device, determine the PDSCH time domain resource allocation information corresponding to the paging message according to the time domain resource allocation indication in the PDCCH and the default PDSCH time domain resource allocation list, and the PDSCH time domain resource allocation information includes the second time domain resource offset;

[0116] The first time domain resource offset and / or the second time domain resource offset is a time slot offset of the PDSCH relative to the PDCCH.

[0117] For example, if UE1 is a power saving terminal, after UE1 receives the PDCCH indicating paging, the time domain resource offset K0_1 of UE1 can be determined based on the time domain resource allocation indication in the PDCCH and the first PDSCH time domain resource allocation list.

[0118] For another example, if UE2 is a non-power-saving terminal, after UE1 receives the PDCCH for indicating paging, if there is a second PDSCH time domain resource allocation list configured by the network device, the time domain resource offset K0_2 of UE2 can be determined based on the time domain resource allocation indication in the PDCCH and the second PDSCH time domain resource allocation list. If there is no second PDSCH time domain resource allocation list, the time domain resource offset K0_2 of UE2 can be determined based on the default PDSCH time domain resource allocation list. Among them, K0_2 can be less than K0_1.

[0119] Optionally, in the second mode, the paging method further includes: the terminal device receives a relative offset of time domain resources configured by the network device for the first type of terminal. Based on the relative offset of time domain resources, the time domain resource offset can be calculated.

[0120] Optionally, the time domain resource relative offset is a PDSCH time domain resource relative offset, and the unit of the PDSCH time domain resource relative offset is a synchronization signal and physical broadcast channel (Physical Broadcast Channel, PBCH) block (Synchronization Signal and PBCH Block, SSB) period or the number of synchronization signal bursts SS bursts.

[0121] Optionally, in the second mode, the terminal device determines the time domain resource allocation information corresponding to the paging message based on the time domain resource allocation indication, the first information and the terminal type, including:

[0122] The terminal device determines the PDSCH time domain resource allocation information corresponding to the paging message based on the time domain resource allocation indication, the PDSCH time domain resource relative offset, the PDSCH time domain resource allocation list, and the terminal type.

[0123] Optionally, the terminal device determines, based on the time domain resource allocation indication, the PDSCH time domain resource relative offset, the PDSCH time domain resource allocation list, and the terminal type, the PDSCH time domain resource allocation information corresponding to the paging message, including at least one of the following:

[0124] In the case where the terminal device is a first type of terminal, if the unit of the PDSCH time domain resource relative offset is an SS burst period, the relative time offset of the PDSCH relative to the PDCCH is determined based on the SS burst period and the PDSCH time domain resource relative offset, and the PDSCH time domain resource allocation information is determined based on the relative time offset, the time domain resource allocation indication and the PDSCH time domain resource allocation list, and the PDSCH time domain resource allocation information includes a first time domain resource offset;

[0125] In the case where the terminal device is a first type of terminal, if the unit of the PDSCH time domain resource relative offset is the number of SS bursts that appear, the terminal device determines the time interval between the moment of receiving the PDCCH and the end moment of the Nth complete SS burst, and based on the time interval, the time domain resource allocation indication and the PDSCH time domain resource allocation list, determines the PDSCH time domain resource allocation information, and the PDSCH time domain resource allocation information includes the first time domain resource offset;

[0126] In the case that the terminal device is a second type of terminal, the terminal device determines the PDSCH time domain resource allocation information based on the time domain resource allocation indication and the PDSCH time domain resource allocation list, and the PDSCH time domain resource allocation information includes a second time domain resource offset.

[0127] For example, for the first type of terminal, if the unit of the PDSCH time domain resource relative offset is SS burst period, for example, the network configures N SSB periods (SSB_period), the UE determines the time offset of the paging PDSCH relative to the paging PDCCH, that is, the first time domain resource offset k0_1=N*SSB_period+k0. Wherein, k0 is the time domain resource offset obtained based on the PDSCH time domain resource allocation list.

[0128] For another example, for the first type of terminal, if the unit of the relative offset of the PDSCH time domain resource is the number of SS bursts, for example, the network configures N SSBs, the UE determines the time interval k0_offset based on N, and then determines the time offset of the paging PDSCH relative to the paging PDCCH, that is, the first time domain resource offset k0_1=k0_offset+k0. Among them, k0 is the time domain resource offset obtained based on the PDSCH time domain resource allocation list.

[0129] For another example, for the second type of terminals, the time offset of the paging PDSCH relative to the paging PDCCH, that is, the second time domain resource offset k0_2=k0, wherein k0 is the time domain resource offset obtained based on the PDSCH time domain resource allocation list.

[0130] Optionally, the paging method further includes:

[0131] The terminal device receives a PDCCH scrambled by a Paging-Radio Network Temporary Identifier (P-RNTI), and the PDCCH scrambled by the P-RNTI is used to indicate paging.

[0132] Optionally, the PDCCH also includes at least one of the following:

[0133] A frequency domain resource allocation indication, where the frequency domain resource allocation indication is used to indicate a frequency domain resource position of a PDSCH corresponding to a received paging message;

[0134] A time domain resource allocation indication, where the time domain resource allocation indication is used to indicate a time domain resource position of a PDSCH corresponding to a received paging message;

[0135] Modulation and Coding Scheme (MCS).

[0136] Optionally, the PDCCH is used to indicate multiple PDSCHs.

[0137] Optionally, the PDCCH is used to indicate a PDSCH for the first category of terminals and a PDSCH for the second category of terminals.

[0138] Exemplarily, the PDCCH is used to indicate two PDSCHs, wherein one PDSCH is for the first type of terminals, and the other PDSCH is for the second type of terminals.

[0139] Exemplarily, if the terminal types include more than 2 types, for example, there are 4 terminal types, the PDCCH may be used to indicate 4 PDSCHs corresponding to the 4 terminal types respectively.

[0140] Optionally, the characteristics of the multiple PDSCHs indicated by the PDCCH include at least one of the following:

[0141] The multiple PDSCHs correspond to the same frequency domain resource position;

[0142] The multiple PDSCHs correspond to the same time domain resource size and different time domain resource positions;

[0143] The multiple PDSCHs correspond to the same MCS or transport block size (Transport Block Size, TBS).

[0144] Optionally, the PDCCH includes a first PDCCH and / or a second PDCCH, the first PDCCH is used to indicate a PDSCH for a first category of terminals, and the second PDCCH is used to indicate a PDSCH for a second category of terminals.

[0145] Optionally, the P-RNTI corresponding to the first PDCCH is different from the P-RNTI corresponding to the second PDCCH, or the first PDCCH and the second PDCCH are PDCCHs that monitor paging in different paging search spaces.

[0146] Exemplarily, if more terminal types are included, more PDCCHs for indicating paging may also be included, respectively indicating PDSCHs for different terminal types. Different PDCCHs have different P-RNTIs, or monitor the paging PDCCHs in different paging search spaces.

[0147] Optionally, the paging method further includes: when the terminal device is a first type terminal, after receiving the PDCCH for indicating paging, the terminal device continues to perform channel measurement and synchronization using the SS burst within a first duration, wherein the first duration includes the time interval between the moment when the PDCCH is received and the moment when the PDSCH is started to be received. In addition, channel measurement and synchronization can also be continued using a Channel State Information Reference Signal (CSI-RS) or a Tracking Reference Signal (TRS) within the first duration.

[0148] In the embodiment of the present application, based on different terminal types, the time domain resource allocation information corresponding to the paging message of the terminal device is determined, which is conducive to achieving terminal energy saving. For example, for a terminal with energy saving requirements, a newly configured time domain resource allocation list and / or a relative offset of time domain resources is used to determine the time domain resource allocation information corresponding to the paging message of the terminal device, and the time domain resource offset in the time domain resource allocation information can be increased, so that the terminal continues to perform channel measurement and synchronization in the SS burst from the time of receiving PDCCH to receiving PDSCH, and the reception performance of PDSCH can be guaranteed. Therefore, the terminal device does not need to wake up in multiple SS burst cycles before PO to start channel detection and synchronization, and the reception performance of PDSCH can be guaranteed. For example, the terminal device can wake up in an SS burst cycle before PO to start synchronization. After the terminal receives PDCCH, the terminal can know whether to continue to receive PDSCH. If the terminal determines to continue to receive PDSCH, the terminal uses the method of this solution to determine the time domain resource offset, and can continue to perform channel measurement and synchronization from the SS burst in the time from receiving PDCCH to starting to receive PDSCH, which can achieve terminal energy saving and ensure PDSCH reception performance.

[0184] The descriptions in the network device execution method 300 of this embodiment that are similar to those in the above-mentioned method 200 have similar meanings. Please refer to the relevant descriptions about network devices such as base stations in the method 200. For the sake of brevity, they will not be repeated here.

[0185] In an application scenario, for a terminal in a non-connected state, the paging method of an embodiment of the present application may be a paging method based on UE grouping, which may mainly include: the network uses different k0 scheduling paging (paging) PDSCH for the first type of terminal and the second type of terminal.

[0186] Optionally, the first type of terminal is a power saving terminal, and the second type of terminal is a non-power saving terminal. For the first type of terminal, the terminal can use a longer time domain resource offset, so that the PDCCH used to indicate paging and the PDSCH indicated by it are not in the same time slot. Therefore, the paging method also belongs to a paging method for cross-time slot scheduling.

[0187] Optionally, the first category of terminals and the second category of terminals use different PDSCH time domain resource allocation lists.

[0188] Optionally, the network configures 1 PDSCH time domain resource allocation list for the first type of terminals.

[0189] Optionally, the terminal determines the PDSCH time domain resource allocation information corresponding to the paging message according to the time domain resource allocation indication in the PDCCH scrambled by the P-RNTI, in combination with the PDSCH time domain resource allocation list and the terminal type corresponding to itself.

[0190] Optionally, the network configures one PDSCH time domain resource relative offset for the first type of terminal, and the unit of the PDSCH time domain resource relative offset is the number of SSB periods or SS burst occurrences.

[0191] Optionally, the terminal determines the PDSCH time domain resource allocation information corresponding to the paging message according to the time domain resource allocation indication in the PDCCH scrambled by the P-RNTI, in combination with the PDSCH time domain resource allocation list, and the terminal type corresponding to itself.

[0192] Optionally, the UE determines its terminal type based on whether it supports cross-carrier scheduling and / or its power saving requirements.

[0193] The following are a few specific examples.

[0194] Example 1

[0195] The network configures a PDSCH time domain resource allocation list for the first type of terminal, and the first type of terminal and the second type of terminal use different PDSCH time domain resource allocation lists. The terminal determines the PDSCH time domain resource allocation information corresponding to the paging message, including the time domain resource offset k0, etc., according to the time domain resource allocation indication in the PDCCH scrambled by the P-RNTI and the PDSCH time domain resource allocation list used by itself. Optionally, the first type of terminal is a power-saving terminal, and the second type of terminal is a non-power-saving terminal. This example may include the following steps:

[0196] Step 1: The UE determines its terminal type, which includes a first-category terminal or a second-category terminal. The division of the first-category terminal and the second-category terminal may include:

[0197] Method 1: According to the power saving requirements of the terminals, power saving terminals are classified as first-category terminals and non-power saving terminals are classified as second-category terminals.

[0198] During the initial UE attachment process, the UE tells the AMF whether it is a power saving terminal or a non-power saving terminal. For example, a 1-bit power saving UE indication field is defined in the REGISTRATION REQUEST message. For example, the REGISTRATION REQUEST message may include the following implementations:

[0199] Option 1: Indicate whether the UE is a power-saving terminal according to whether the REGISTRATION REQUEST message carries the Power saving UE indication field. For example, if the Power saving UE indication field is carried, the UE is indicated as a power-saving terminal; otherwise, the UE is indicated as a non-power-saving terminal. For another example, if the Powersaving UE indication field is carried, the UE is indicated as a non-power-saving terminal; otherwise, the UE is indicated as a power-saving terminal.

[0200] Option 2: Indicate whether the UE is a power-saving terminal according to the value of the Power saving UE indication field in the REGISTRATION REQUEST message. For example, if the Power saving UE indication field is 0, it indicates that the UE is a power-saving terminal, and if it is 1, it indicates that the UE is a non-power-saving terminal. For another example, if the Power saving UE indication field is 1, it indicates that the UE is a power-saving terminal, and if it is 0, it indicates that the UE is a non-power-saving terminal.

[0201] For example, considering backward compatibility, the R15 / R16 terminal may not carry the Power saving UE indication field in the REGISTRATION REQUEST message sent, and this case can also be regarded as a non-power saving terminal.

[0202] Mode 2: According to the terminal capabilities, terminals that support cross-time slot scheduling are classified as first-category terminals, and terminals that do not have this capability are classified as second-category terminals.

[0203] The UE can inform the network whether it supports cross-slot scheduling through capability reporting.

[0204] Mode 3: Based on the terminal capability and the power saving requirement of the terminal, the power saving terminals supporting cross-carrier scheduling are classified as the first type of terminals, and otherwise as the second type of terminals.

[0205] Step 2: The UE receives a network system message and configures a first PDSCH time domain resource allocation list. Optionally, the network may also configure a second PDSCH time domain resource allocation list. The UE determines its corresponding PDSCH time domain resource allocation list according to the configuration information.

[0206] For the first type of terminals, the first PDSCH time domain resource allocation list configured is used;

[0207] For the second type of terminals, if the network configures a second PDSCH time domain resource allocation list, the UE uses the configured second PDSCH time domain resource allocation list; if the network does not configure the second PDSCH time domain resource allocation list, the UE uses the default PDSCH time domain resource allocation list defined by the protocol.

[0208] Step 3: For a PO, when the network is to map paging to at least one UE on the PO, the network may send a PDCCH for indicating paging by:

[0209] Method 1: The network sends a PDCCH for indicating paging. This PDCCH can indicate two PDSCHs at the same time. The two PDSCHs are PDSCHs corresponding to the paging message. One of the two PDSCHs is for the first type of terminal, see Figure 4 PDSCH1; another PDSCH for the second type of terminal, see Figure 4 PDSCH2.

[0210] The two PDSCHs have the following characteristics:

[0211] The two PDSCHs correspond to the same frequency domain resource position;

[0212] The two PDSCHs correspond to the same time domain resource size and different time domain resource positions, that is, different k0 values;

[0213] The two PDSCHs correspond to the same MCS or TBS.

[0214] The above indication of two PDSCHs through PDCCH is only an example and not a limitation. It should be understood that if more terminal types are set, more PDSCHs can also be indicated through PDCCH, so as to respectively indicate PDSCHs for different terminal types through PDCCH.

[0215] In addition, the PDCCH used to indicate paging may include:

[0216] 1 frequency domain resource allocation indication;

[0217] 1 time domain resource allocation indication;

[0218] 1 MCS.

[0219] Mode 2: The network sends PDCCHs for indicating paging to the first type of terminals and the second type of terminals respectively. For this mode, the first type of terminals and the second type of terminals use different P-RNTIs, or monitor the paging PDCCH in different paging search spaces.

[0220] Step 4: The UE determines the time-frequency resource location for receiving the PDSCH (which may be referred to as paging PDSCH) corresponding to the paging message according to the indication in the received PDCCH.

[0221] For example, the frequency domain resource position is determined according to the frequency domain resource indication in the received PDCCH.

[0222] For another example, the time domain resource position is determined according to the time domain resource indication in the PDCCH in combination with the PDSCH time domain resource allocation list used by the UE, as follows:

[0223] If the UE is a first type of terminal, the PDSCH time domain resource allocation information, including k0_1, etc., is determined according to the time domain resource indication in the PDCCH and in combination with the first PDSCH time domain resource allocation list.

[0224] If the UE is a second-category terminal, the PDSCH time domain resource allocation information, including k0_2, etc., is determined according to the time domain resource indication in the PDCCH and in combination with the PDSCH time domain resource allocation list used by the second-category terminal.

[0225] Step 5: For the first type of terminal, after receiving the PDCCH indicating paging, the SS burst before receiving the PDSCH corresponding to the paging message can be used to continue channel measurement and synchronization to ensure the reception performance of the PDSCH. Figure 4The time K0_1 before the first type of terminal receives the PDCCH indicating paging and the PDSCH corresponding to the paging message is longer than K0_2 of the second type of terminal, which can meet the needs of channel measurement and synchronization. Therefore, the first type of terminal does not need to wake up multiple SS bursts before receiving the PDCCH to perform channel measurement and synchronization, achieving terminal energy saving.

[0226] Example 2

[0227] The network configures a PDSCH time domain resource relative offset for the first type of terminal, and the unit of the PDSCH time domain resource relative offset is the number of SSB cycles or SS bursts. The terminal determines the PDSCH time domain resource allocation information corresponding to the paging message according to the time domain resource allocation indication in the PDCCH scrambled by P-RNTI combined with the PDSCH time domain resource allocation list and the terminal type corresponding to itself. The first type of terminal is a power-saving terminal, and the second type of terminal is a non-power-saving terminal.

[0228] This example may include the following steps:

[0229] Step 1: The UE determines its own terminal type, which includes a first-category terminal or a second-category terminal. The division method of the first-category terminal and the second-category terminal can refer to the relevant description of Example 1.

[0230] Step 2: The UE receives a network system message and configures PDSCH time domain resource allocation related parameters, including: configuring a PDSCH time domain resource relative offset, which is used by the first type of terminal to determine an offset k0 corresponding to the PDSCH time domain resource corresponding to the paging message. The unit of the PDSCH time domain resource offset can be an SS burst period, such as several SS burst periods, or the number of SS bursts.

[0231] Optionally, the network configures a PDSCH time domain resource allocation list. The UE determines its corresponding PDSCH time domain resource allocation list based on whether the configuration information exists. If the network configures the PDSCH time domain resource allocation list, the UE uses the configured PDSCH time domain resource allocation list. If the network does not configure the PDSCH time domain resource allocation list, the UE uses the default PDSCH time domain resource allocation list defined by the protocol.

[0232] Step 3. For a PO, when the network wants to page at least one UE mapped to the PO, the network sends a PDCCH indicating paging. The 1 PDCCH can simultaneously indicate 2 PDSCHs, one of which is for the first type of terminal and the other is for the second type of terminal.

[0233] The two PDSCHs have the following characteristics:

[0234] The two PDSCHs correspond to the same frequency domain resource position;

[0235] The two PDSCHs correspond to the same time domain resource size and different time domain resource positions;

[0236] The two PDSCHs correspond to the same MCS or TBS.

[0237] In addition, the PDCCH used to indicate paging may include:

[0238] 1 frequency domain resource allocation indication;

[0239] 1 time domain resource allocation indication;

[0240] 1 MCS.

[0241] Step 4: The UE determines the time-frequency resource location for receiving the PDSCH corresponding to the paging message according to the indication in the received PDCCH.

[0242] For example, the frequency domain resource position is determined according to the frequency domain resource indication in the received PDCCH.

[0243] For another example, the time domain resource position determines a k0 according to the time domain resource indication in the PDCCH and the PDSCH time domain resource allocation list used by the UE, and the method is as follows:

[0244] (1) For Category 1 terminals:

[0245] See also Figure 5 If the unit of the relative offset of the first PDSCH time domain resource is SS burst period, such as N SSB periods, then the time offset of the Paging PDSCH relative to the paging PDCCH is determined to be k0_1=N*SSB_period+k0.

[0246] See also Figure 6 If the unit of the first PDSCH time domain resource relative offset is the number of SS bursts, such as N SSBs, the UE first determines k0_offset as the time interval between the moment of receiving the PDCCH for indicating paging and the moment of the end of the Nth complete SS burst, then the time offset k0_1=k0_offset+k0 of the PDSCH corresponding to the paging message received by the UE relative to the PDCCH for indicating paging is received.

[0247] (2) For the second type of terminals, it is determined that the time offset of the PDSCH corresponding to the paging message relative to the PDCCH used to indicate the paging message is k0_2=k0.

[0248] Step 5: For the first type of terminal, after receiving the PDCCH indicating paging, the SS burst in the period before the PDSCH corresponding to the paging message is received can be used to continue channel measurement and synchronization to ensure the reception performance of the PDSCH.

[0249] The paging method of the embodiment of the present application is a paging method based on UE grouping, and different k0 values ​​are used to indicate PDSCH reception for non-power-saving terminals and power-saving terminals. For the first type of terminal, the terminal can use a longer k0_1, so that the PDCCH and the PDSCH indicated by it are not in the same time slot. Therefore, the paging method of the embodiment of the present application belongs to a paging method for cross-time slot scheduling.

[0250] Using this method, for UEs with power saving requirements, they only need to wake up in a few SS burst cycles before PO to complete the synchronization for PDCCH. If the UE receives PDCCH on its corresponding PO, the UE can continue to perform channel measurement and synchronization using the SS burst during this period before PDSCH reception after receiving PDCCH to ensure the reception performance of PDSCH. If the UE does not receive PDCCH on its corresponding PO, the UE can immediately return to sleep. Therefore, this method can reduce unnecessary synchronization time of the UE and save UE power consumption.
