[0069] In some embodiments, a core network device may be a single device comprising one or more network elements, or may be a plurality of devices or a group of devices, each comprising all or part of one or more network elements. A network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0071] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1 , or a part of the main body thereof, but are not limited thereto.

[0072] The entities shown in Figure 1 are examples. The communication system may include all or part of the entities in Figure 1, and may also include other entities outside of Figure 1. The number and form of the entities are arbitrary. The connection relationship between the entities is an example.

[0074] In the disclosed embodiment, for an RRC-IDLE user equipment 101 with the LP WUS monitoring function enabled, if the user equipment 101 monitors the LP WUS corresponding to the user equipment 101, the host will be awakened. After waking up, the host will perform a paging process, that is, monitor the PO corresponding to the user equipment 101.

[0075] In the embodiment of the present disclosure, the user equipment 101 can obtain the time domain position of a paging occasion (PO), and it is necessary to solve how to obtain or determine the LP WUS resource corresponding to the PO in this scenario.

[0076] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for a communication system 100, the method comprising:

[0077] In step S2101 , the network device 102 sends configuration information to the user equipment 101 .

[0078] In some embodiments, the user device 101 receives configuration information sent by the network device 102 .

[0079] In some embodiments, the configuration information is used to indicate the correspondence between LP WUS resources and paging occasions PO.

[0080] That is, network device 102 informs user equipment 101 of the correspondence between LP WUS resources and paging occasions (POs) through configuration information. User equipment 101 can obtain the time-frequency location of the PO, for example, the PO index. After obtaining the PO index, user equipment 101 can determine the LP WUS resource based on this correspondence and monitor the LP WUS based on the LP WUS resource. This allows user equipment 101 to monitor the LP WUS at the appropriate time-frequency location, allowing for timely wakeup and ensuring a short communication establishment delay. It will be appreciated that the manner in which user equipment 101 determines the PO index can be found in the description of the following embodiments.

[0081] In some embodiments, the LP WUS resource may include at least one of the following:

[0082] Time domain resources of LP WUS;

[0083] Frequency domain resources of LP WUS;

[0084] LP WUS's code domain resources.

[0085] Optionally, taking the time domain resource of the LP WUS as an example, the time domain resource of the LP WUS may be a sending opportunity of the LP WUS.

[0086] Optionally, taking the frequency domain resources of the LP WUS as an example, the frequency domain resources of the LP WUS may be the transmission frequency domain resources of the LP WUS.

[0087] Optionally, taking the code domain resource of the LP WUS as an example, the code domain resource of the LP WUS may be an orthogonal code sequence for sending the LP WUS.

[0088] In some embodiments, the PO is used to transmit paging downlink control information (Paging DCI), which is DCI scrambled by the Paging Radio Network Temporary Identity (P-RNTI). The Paging DCI is used to schedule the Physical Downlink Shared Channel (PDSCH) that carries the paging message.

[0089] In some embodiments, the correspondence between LP WUS resources and POs may be that one LP WUS resource corresponds to at least one PO, or at least one LP WUS resource corresponds to one PO.

[0090] That is, one LP WUS resource may correspond to one or more POs, or multiple LP WUS resources may correspond to one PO.

[0091] For example, one LP WUS resource corresponds to K POs, K≥1; or one PO corresponds to S LP WUS resources, S≥1. Here, the values ​​of K and S can be adjusted as needed, and this disclosure does not limit this.

[0092] It can be understood that the correspondence between LP WUS resources and PO can be understood as being able to determine the LP WUS resources according to the time-frequency position of the PO, that is, determining the time domain resources and / or frequency domain resources and / or code domain resources of the LP WUS.

[0093] The following takes the LP WUS resource as the time domain resource of the LP WUS as an example to illustrate the corresponding relationship between the LP WUS resource and the PO.

[0094] In some embodiments, LP WUS resources include LP WUS transmission opportunities, and the LP WUS transmission opportunities are periodic. For example, for a user device 101, its corresponding LP WUS transmission opportunity may occur periodically. Taking the LP WUS transmission period t as an example, the LP transmission opportunity of the user device 101 may occur once every interval of t. For another example, for multiple user devices 101, an LP WUS transmission period t' may include LP WUS transmission opportunities corresponding to multiple user devices 101, that is, t' includes multiple LP WUS transmission opportunities; alternatively, the LP WUS transmission opportunities of each user device 101 repeat at a corresponding period. It will be understood that the LP WUS transmission period corresponding to the user device 101 may be configured by the network device 102. For example, the network device 102 may configure the LP WUS transmission period (LP WUS cycle).

[0095] In some embodiments, each LP WUS transmission period includes M LP WUS transmission opportunities, where M≥1; the M LP WUS transmission opportunities may correspond to different user equipments 101 , respectively.

[0096] For example, for the same user equipment 101, its corresponding LP WUS transmission opportunity may occur only once in an LP WUS transmission cycle. The M LP WUS transmission opportunities included in the LP WUS transmission cycle correspond one-to-one to the M user equipment groups, or in other words, each LP WUS transmission opportunity may correspond to a group of user equipment 101.

[0097] In some embodiments, each LP WUS transmission opportunity corresponds to K POs in a paging cycle.

[0098] It can be understood that the K POs may be part of the POs in a paging cycle, that is, the total number of POs included in a paging cycle may be greater than K.

[0099] Optionally, when the network device 102 configures one LP WUS sending opportunity to correspond to K POs, M*K=N*N s , where N is the number of PFs in a paging cycle, N s The number of POs in a PF, N*N s Indicates the total number of POs in a paging cycle. The value of M*K is equal to the total number of POs in a paging cycle, or in other words, M and / or K are factors of the total number of POs in a paging cycle.

[0100] A paging frame PF may include multiple POs.

[0101] In one example, when each LP WUS transmission opportunity corresponds to K POs in a paging cycle, the PO index (index) of the PO corresponding to the first LP WUS transmission opportunity among M LP WUS transmission opportunities includes: mK to (m+1)*K-1. The meaning of "~" indicates that the PO index satisfies the range from index mK to index (m+1)*K-1, or in other words, mK ≤ PO index ≤ (m+1)*K-1. It will be understood that the meaning of "~" in the following embodiments can refer to the description herein, that is, the value includes the upper limit, the lower limit, and the portion between the upper limit and the lower limit.

[0102] The PO indexes of all POs in one paging cycle meet the set order, the indexes of the M LP WUS transmission opportunities are 0 to (M-1), the index of the first LP WUS transmission opportunity is m, and 0≤m≤(M-1).

[0103] For example, the PO index may be set in an ascending order, such as the PO index in a paging cycle includes: PO 0 to PO (N*N s -1).

[0104] In another example, when each LP WUS transmission opportunity corresponds to K POs in one paging cycle, among the M LP WUS transmission opportunities, the PF index of the paging frame PF corresponding to the first LP WUS transmission opportunity includes:

[0105] in, is the PF index of the first PF, is the PF index of the second PF, that is PF index corresponding to the first LP WUS sending opportunity

[0106] The PO index of the PO corresponding to the first LP WUS sending opportunity includes: the PO index mK-N in the first PF s * PO index in the second PF That is, the PO index in the first PF The PO index corresponding to the first LP WUS sending opportunity ≤ the PO index in the second PF

[0107] Among them, the PF indexes of all paging frames PF in a paging cycle meet the set order, and each PF includes N s PO, the index of the first LP WUS sending opportunity is m, 0≤m≤(M-1); is the PO index in the first PF, PO index in the second PF.

[0108] For example, the PF index can be set in order from low to high, such as the PF index in a paging cycle includes: PF0 to PF (N-1). The POs contained in each PF are numbered in sequence, such as the PO index in each PF can be PO0-PO (N s -1).

[0109] In some embodiments, when each LP WUS transmission opportunity corresponds to K POs in a paging cycle, the time interval between the LP WUS transmission opportunity and the second PO is greater than or equal to the first duration, wherein the second PO is the earliest PO in the time domain among the K POs corresponding to the LP WUS transmission opportunity.

[0110] Optionally, among the K POs corresponding to an LP WUS sending opportunity, the PO indexes are arranged in ascending order, and the second PO may be the earliest PO in the time domain among the K POs, that is, the earliest PO in the time domain among the K POs.

[0111] Optionally, the time interval between the LP WUS sending opportunity and the second PO is greater than or equal to the first duration T1. The first duration T1 can be used to meet the transition time of the user equipment 101 from the sleep state to the working state, so as to monitor the associated PO in time.

[0112] In one example, the first duration is configured by the network device 102 or defined by a protocol.

[0113] In some embodiments, every S LP WUS transmission opportunities correspond to one PO in one paging cycle.

[0114] It is understandable that the number of POs in a paging cycle may be greater than one.

[0115] Optionally, when the network device 102 configures S LP WUS sending opportunities to correspond to one PO, Among them, N is the number of PFs in a paging cycle, N s The number of POs in a PF, N*N s Indicates the total number of POs in a paging cycle. The value of is equal to the total number of POs in a paging cycle, or in other words, M is a multiple of the total number of POs in a paging cycle.

[0116] In one example, when every S LP WUS transmission opportunities corresponds to one PO in one paging cycle, among the M LP WUS transmission opportunities, the PO index of the PO corresponding to the first LP WUS transmission opportunity is: The PO indexes of all POs in one paging cycle meet the set order, the indexes of the M LP WUS transmission opportunities are 0 to (M-1), the index of the first LP WUS transmission opportunity is m, and 0≤m≤(M-1).

[0117] For example, the PO index may be set in an ascending order, such as the PO index in a paging cycle includes: PO 0 to PO (N*N s -1).

[0118] In another example, when every S LP WUS transmission opportunities corresponds to one PO in one paging cycle, among the M LP WUS transmission opportunities, the PF index corresponding to the first LP WUS transmission opportunity is: The PO index of the PO corresponding to the first LP WUS sending opportunity is: Among them, the PF indexes of all paging frames PF in a paging cycle meet the set order, and each PF includes N s The index of the first LP WUS sending opportunity is m, 0≤m≤(M-1).

[0119] It can be understood that, in this example, the PO index corresponding to the first LP WUS transmission opportunity corresponds to the PO in the PF of the PF index corresponding to the first LP WUS transmission opportunity.

[0120] In this example, the PF index can be set in order from low to high, such as the PF index in a paging cycle includes: PF 0 to PF (N-1). The POs contained in each PF are numbered in sequence, such as the PO index in each PF can be PO 0-PO (N s -1).

[0121] In some embodiments, when every S LP WUS sending opportunities correspond to one PO in a paging cycle, the time interval between the second LP WUS sending opportunity and the corresponding PO is greater than or equal to the second duration; the second LP WUS sending opportunity is the last LP WUS sending opportunity in the time domain among the S LP WUS sending opportunities corresponding to the PO.

[0122] Optionally, among the S LP WUS transmission opportunities, the indexes of the LP WUS transmission opportunities may be arranged in ascending order, and the second LP WUS transmission opportunity is the last LP WUS transmission opportunity in the time domain among the S LP WUS transmission opportunities.

[0123] Optionally, the time interval between the second LP WUS sending opportunity and the PO is greater than or equal to a second duration T2, and the second duration T2 can be used to meet the transition time of the user equipment 101 from the sleep state to the working state, so as to monitor the associated PO in time.

[0124] Optionally, the second duration T2 may be equal to or different from the first duration T1.

[0125] In one example, the second duration is configured by the network device 102 or defined by a protocol.

[0126] Step S2102 : The network device 102 sends an LP WUS to the user equipment 101 .

[0127] In some embodiments, before the user equipment 101 receives the LP WUS, the host may be in a sleep state to save energy, and a separate low-power receiver may be used to listen for the LP WUS.

[0128] In some embodiments, the user equipment 101 may be a device in a Radio Resource Control (RRC) idle state (IDLE) or an RRC inactive state (INACTIVE).

[0129] In some embodiments, when the network device 102 needs to wake up the user equipment 101 , it may send an LP WUS indicating the user equipment 101 is awakened.

[0130] In some embodiments, the LP WUS includes indication information;

[0131] The indication information is used to indicate whether the user equipment 101 needs to wake up to monitor the PO corresponding to the LP WUS resource.

[0132] Optionally, the network device 102 carries the indication information when sending the LP WUS.

[0133] In some embodiments, the indication information includes a first information field, and the first information field is used to indicate whether the user equipment 101 or the user equipment group associated with the PO corresponding to the LP WUS needs to be awakened.

[0134] Optionally, a user equipment group (UE subgrouping) may include multiple user equipments 101 .

[0135] Optionally, the user equipment 101 associated with the PO may be one or more.

[0136] Optionally, network device 102 may configure PO resources for user equipment 101. For a user equipment 101, its corresponding PO occurs periodically. For multiple user equipment 101, these multiple user equipment 101 may use the same set of periodic PO resources. From the perspective of network device 102, one or more POs may be configured in a paging cycle, where each PO is associated with a group of UEs.

[0137] Optionally, the first information field may occupy at least one bit.

[0138] In the first example, the first information field includes K bits, wherein the K bits correspond one-to-one to K POs corresponding to the LP WUS sending opportunities, and each bit is used to indicate whether the user equipment 101 associated with the corresponding PO needs to be awakened.

[0139] This example is applicable to the scenario where one LP WUS sending opportunity corresponds to K POs.

[0140] In this example, each bit corresponds to a PO, and whether the user equipment 101 associated with the PO needs to be awakened is determined according to the value of the bit, that is, whether the user equipment 101 needs to be switched from a sleep state to a working state.

[0141] For example, when the bit is 1, it indicates that the user equipment 101 associated with the PO corresponding to the bit needs to be awakened; when the bit is 0, it indicates that the user equipment 101 associated with the PO corresponding to the bit does not need to be awakened.

[0142] In this example, when K=4, that is, one LP WUS sending opportunity corresponds to four POs, the first information field may include four bits, each bit being used to indicate whether to wake up the user equipment 101 associated with the PO and monitor the PO.

[0143] In the second example, the first information field includes K*L bits, where each of the K POs corresponding to the LP WUS sending opportunity corresponds to L bits, and each bit is used to indicate whether the user equipment group associated with the corresponding PO needs to be awakened, and L is the number of user equipment groups associated with each PO.

[0144] This example is applicable to the scenario where one LP WUS sending opportunity corresponds to K POs.

[0145] In this example, each PO is associated with L user equipment groups, where L≥1. The K*L bits serve as UE subgrouping indication, and are used to indicate whether the related user equipment group needs to be woken up.

[0146] For example, when K=4 and L=8, that is, one LP WUS sending opportunity corresponds to 4 POs, and each PO is associated with 8 user equipment groups, then the first information field may include 4×8=32 bits, where each bit is used to indicate whether to wake up the user equipment group associated with the PO to monitor the corresponding PO.

[0147] It can be understood that when a user equipment group needs to be awakened, it indicates that all user equipments 101 in the user equipment group are awakened.

[0148] In the third example, the first information field includes K bits; wherein the K bits correspond one-to-one to K POs, and each bit is used to indicate whether a plurality of user equipment groups associated with the corresponding PO need to be awakened.

[0149] This example is applicable to the scenario where one LP WUS sending opportunity corresponds to K POs.

[0150] In this example, each PO is associated with multiple user equipment groups, and the wake-up indication is performed in units of PO (per PO).

[0151] For example, when the value of the 1 bit corresponding to the PO is 1, it indicates that the user equipment 101 of all user equipment groups associated with the PO needs to be awakened; when the value of the 1 bit corresponding to the PO is 0, it indicates that the user equipment 101 of all user equipment groups associated with the PO does not need to be awakened.

[0152] For another example, if K is 4, that is, one LP WUS transmission opportunity corresponds to four POs, then the first information field may include four bits. Each PO is associated with eight user equipment groups. When the value of one bit corresponding to the PO is 1, all eight user equipment groups corresponding to the bit need to be awakened.

[0153] In the fourth example, the first information field includes one bit;

[0154] One bit corresponds to K POs, and one bit is used to indicate whether a plurality of user equipment groups associated with the K POs need to be awakened.

[0155] This example is applicable to the scenario where one LP WUS sending opportunity corresponds to K POs.

[0156] In this example, each PO may be associated with at least one user equipment group, and K POs are combined for indication.

[0157] For example, the K POs correspond to the same bit. When the bit value is 1, it indicates that all user equipment groups associated with the K POs need to be awakened; when the bit value is 0, it indicates that all user equipment groups associated with the K POs do not need to be awakened.

[0158] Step S2103 : The user equipment 101 monitors the LP WUS sent by the network equipment 102 according to the configuration information.

[0159] In some embodiments, the user equipment 101 determines the LP WUS resources according to the configuration information.

[0160] In some embodiments, the user equipment 101 may learn the time domain location of the PO. For example, the user equipment 101 may determine the time domain location of the PO corresponding to itself based on the system frame number (SFN) of the paging frame (PF) in which the PO is located and the index of the PO in the PF.

[0161] In some embodiments, the user equipment 101 determines the SFN of the PF in the following manner: (SFN+PF_offset) mod T=(T div N)*(UE_ID mod N);

[0162] Where PF_offset is the time domain offset of the PF frame, in frames. T is the paging cycle of user equipment 101, in frames. N is the number of PFs in a paging cycle. UE ID is the identifier of user equipment 101. mod is the remainder operation, and div is the integer division operation.

[0163] In some embodiments, the user equipment 101 determines the PO index of the PO in the PF in the following manner: i_s=floor(UE_ID / N)mod N s ;

[0164] Among them, i_s represents the PO index, N is the number of PFs in a paging cycle, N s is the number of POs in a PF. UE ID is the identifier of the user equipment 101. Floor is a round-down operation.

[0165] The parameters other than the UE ID mentioned above may be configured by the network device 102 through a broadcast message, so the user equipment 101 may calculate and determine the corresponding PF or PO according to its own UE ID.

[0166] In some embodiments, after learning the time domain position of the PO, the user equipment 101 may determine the LP WUS resources corresponding to the PO, such as the LP WUS time domain resources, according to the corresponding relationship of the configuration information.

[0167] In some embodiments, the user equipment 101 may monitor the LP WUS at a suitable time-frequency position according to the LP WUS resources.

[0168] Step S2104 : The user equipment 101 switches from the sleep state to the working state, and monitors the PO associated with the user equipment 101 .

[0169] In some embodiments, step S2104 is performed when the LP WUS instructs the user equipment 101 to wake up.

[0170] In some embodiments, according to the indication information carried by the LP WUS in step S2103 , the user equipment 101 may determine whether it needs to wake up when receiving the LP WUS.

[0171] In one example, when each LP WUS sending opportunity corresponds to K POs, the user equipment 101 monitors the LP WUS according to the corresponding relationship. If the LP WUS corresponding to itself is received in the LP WUS sending opportunity indexed as m in the aforementioned embodiment, and the LP WUS indicates wake-up, all user equipment 101 associated with the K POs corresponding to the LP WUS sending opportunity will be woken up.

[0172] In another example, the LP WUS is sent at any LP WUS sending opportunity among the S LP WUS sending opportunities corresponding to the PO, and the LP WUS indicates whether all or part of the associated user equipments 101 need to wake up.

[0173] This example applies to a scenario where every S LP WUS transmission opportunities corresponds to one PO. User equipment 101 begins monitoring the LP WUS at a first time domain location. When a corresponding LP WUS is received at any of the S LP WUS transmission opportunities, and the LP WUS indicates wakeup, all or some user equipment 101 associated with the PO corresponding to the LP WUS transmission opportunity are woken up.

[0174] Optionally, when an LP WUS is sent at any one of the S LP WUS sending opportunities and the LP WUS indicates wake-up, all user equipments 101 corresponding to the PO corresponding to the S LP WUS sending opportunities will be woken up.

[0175] Optionally, when an LP WUS is sent at any one of the S LP WUS sending opportunities and the LP WUS indicates wake-up, some user equipments 101 corresponding to the PO corresponding to the S LP WUS sending opportunities may also be woken up.

[0176] The UE IDs of all user equipment 101 corresponding to the PO satisfy the following conditions: The identifiers of some user equipment 101 that need to be awakened may meet the following conditions:

[0177] For example, in at least one user equipment 101 associated with the LP WUS transmission opportunity with index s, the user equipment identifier UE ID of the user equipment 101 to be awakened satisfies:

[0178] Among them, 0≤s≤(S-1).

[0179] In some embodiments, when the user device 101 needs to be awakened, the host can perform the awakening, such as switching from a sleep state to a working state. After waking up, the user device 101 can monitor the PO associated with itself.

[0180] It can be understood that the user equipment 101 in RRC-IDLE or RRC-INACTIVE needs to periodically monitor the paging messages transmitted in the PO, and after receiving the paging message, it can enter the RRC connected state (CONNECTED) and communicate normally with the network device 102.

[0181] For example, the operation of the user equipment 101 monitoring the paging message includes: the user equipment 101 monitoring whether there is a DCI scrambled by using the P-RNTI in the PO associated with itself.

[0182] If the user equipment 101 monitors the DCI scrambled by the P-RNTI in the PO, and the setting information field in the DCI indicates that the DCI schedules the PDSCH carrying the paging message, the user equipment 101 receives and demodulates the PDSCH according to the instruction of the DCI. The setting information field may be a Short Messages Indicator information field.

[0183] If the user equipment 101 does not hear the DCI scrambled by the P-RNTI in the PO, or hears the DCI scrambled by the P-RNTI but the setting information field in the DCI indicates no paging message, the user equipment 101 may not receive and demodulate the PDSCH.

[0184] In some embodiments, the user equipment 101 may also monitor system information or system short messages after waking up. The system short messages are messages directly carried in the paging DCI and do not need to be carried by scheduling PDSCH.

[0185] Step S2105 : The user equipment 101 switches from the working state to the sleeping state.

[0186] In some embodiments, when the total number of times the user equipment 101 monitors PO in different paging cycles is greater than or equal to a threshold and no paging message corresponding to the user equipment 101 is monitored, step S2105 is executed.

[0187] In some embodiments, the threshold is configured by the network device or defined by the protocol.

[0188] In some embodiments, in combination with the description of the above embodiments, the correspondence between LP WUS resources and POs is: a correspondence between an index of an LP WUS transmission opportunity within an LP WUS transmission cycle and an index of a PO within a paging cycle.

[0189] In one example, in a scenario where an LP WUS transmission opportunity corresponds to K POs in a paging cycle, the time interval between the LP WUS transmission opportunity and the second PO is greater than or equal to the first duration T1, and the second PO is the earliest PO in the time domain among the K POs corresponding to the LP WUS transmission opportunity.

[0190] In this example, after the user equipment 101 is awakened by the LP WUS, it can monitor paging on the first PO associated with the UE after the first time length T1 from the LP WUS sending opportunity, but is not limited to this. The user equipment 101 can also continue to monitor paging on the PO corresponding to the UE in multiple subsequent paging cycles.

[0191] When the total number of times the user equipment 101 monitors PO is greater than or equal to the threshold and no corresponding paging message is monitored, the user equipment 101 may enter the sleep state again to achieve energy saving.

[0192] It can be understood that, combined with the description of the foregoing embodiments, for a user device 101, it corresponds to only one PO in one paging cycle, and when monitoring multiple POs, it needs to be implemented in multiple paging cycles. Therefore, the number of monitoring times is used to indicate whether the user device 101 has adjusted the monitored paging cycle.

[0193] In some embodiments, the order of steps S2102 and S2103 is for illustration only. For example, when the network device 102 sends the LP WUS after the first time domain position, step S2103 may be executed before step S2102, that is, the user equipment 101 monitors the LP WUS in advance.

[0194] In some embodiments, steps S2102, S2104 and S2105 are optional.

[0195] In some embodiments, the method includes steps S2101 and S2103.

[0196] In some embodiments, the method includes steps S2101 , S2102 and S2103 .

[0197] In some embodiments, the method includes steps S2101 , S2102 , S2103 , and S2104 .

[0198] In some embodiments, the method includes steps S2101 to S2105.

[0199] In the disclosed embodiment, network device 102 sends configuration information to user device 101 to inform it of the correspondence between LP WUS resources and POs. After receiving the configuration information, user device 101 can determine the LP WUS resource to monitor based on the time domain location of its corresponding PO and the correspondence indicated in the configuration information. This allows user device 101 to monitor the LP WUS in a timely manner at a reasonable location, allowing it to wake up in a timely manner even in an energy-saving state.

[0200] FIG3 is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the embodiment of the present disclosure relates to a communication method for a user device 101, the method comprising:

[0201] In step S3101 , the user equipment 101 receives configuration information sent by the network equipment 102 .

The PO indexes of all POs within a paging cycle satisfy a set order. The indexes of the M LP WUS transmission opportunities range from 0 to (M-1), and the index of the first LP WUS transmission opportunity is m, where 0≤m≤(M-1).

[0213] In another example, among the M LP WUS transmission opportunities, the PF index of the paging frame PF corresponding to the first LP WUS transmission opportunity includes:

[0214] in, is the PF index of the first PF, PF index of the second PF;

[0215] The PO index of the PO corresponding to the first LP WUS sending opportunity includes: the PO index in the first PF PO index in the second PF

[0217] In some embodiments, when each LP WUS transmission opportunity corresponds to K POs in a paging cycle, the time interval between the LP WUS transmission opportunity and the second PO is greater than or equal to the first duration, wherein the second PO is the earliest PO in the time domain among the K POs corresponding to the LP WUS transmission opportunity.

[0218] In one example, the first duration is configured by the network device 102 or defined by a protocol.

[0219] In some embodiments, every S LP WUS transmission opportunities correspond to one PO in one paging cycle.

[0220] In one example, among M LP WUS transmission opportunities, the PO index of the PO corresponding to the first LP WUS transmission opportunity is: The PO indexes of all POs in one paging cycle satisfy a set order, the indexes of the M LP WUS transmission opportunities are 0 to (M-1), the index of the first LP WUS transmission opportunity is m, and 0≤m≤(M-1).

[0221] In another example, among the M LP WUS transmission opportunities, the PF index corresponding to the first LP WUS transmission opportunity is:

[0223] It can be understood that, in this example, the PO index corresponding to the first LP WUS transmission opportunity corresponds to the PO in the PF of the PF index corresponding to the first LP WUS transmission opportunity.

[0224] In some embodiments, when every S LP WUS sending opportunities correspond to one PO in a paging cycle, the time interval between the second LP WUS sending opportunity and the corresponding PO is greater than or equal to the second duration; the second LP WUS sending opportunity is the last LP WUS sending opportunity in the time domain among the S LP WUS sending opportunities corresponding to the PO.

[0225] In one example, the second duration is configured by the network device 102 or defined by a protocol.

[0226] Step S3102 : The user equipment 101 monitors the LP WUS sent by the network device 102 according to the configuration information.

[0227] In some embodiments, the implementation of step S3102 can refer to the relevant implementations of steps S2102 to S2103, and will not be repeated here.

[0228] In some embodiments, the LP WUS includes indication information;

[0229] The indication information is used to indicate whether the user equipment 101 needs to wake up to monitor the PO corresponding to the LP WUS resource.

[0230] In some embodiments, the indication information includes a first information field, and the first information field is used to indicate whether the user equipment 101 or the user equipment group associated with the PO needs to be awakened.

[0231] In the first example, the first information field includes K bits, wherein the K bits correspond one-to-one to K POs corresponding to the LP WUS sending opportunities, and each bit is used to indicate whether the user equipment 101 associated with the corresponding PO needs to be awakened.

[0232] In the second example, the first information field includes K*L bits, where each of the K POs corresponding to the LP WUS sending opportunity corresponds to L bits, and each bit is used to indicate whether the user equipment group associated with the corresponding PO needs to be awakened, and L is the number of user equipment groups associated with each PO.

[0236] Step S3103 : The user equipment 101 switches from the sleep state to the working state, and monitors the PO associated with the user equipment.

[0237] In some embodiments, the implementation of step S3103 can refer to the relevant implementation of step S2104 and will not be repeated here.

[0238] In some embodiments, when the LP WUS instructs the user equipment to wake up, step S3103 is performed again.

[0239] In an example, the LP WUS is sent at any LP WUS sending opportunity among the S LP WUS sending opportunities corresponding to the PO, and the LP WUS indicates whether all or part of the associated user equipments 101 need to wake up.

[0273] In another example, among the M LP WUS transmission opportunities, the PF index corresponding to the first LP WUS transmission opportunity is:

[0274] The PO index of the PO corresponding to the first LP WUS sending opportunity is: Among them, the PF indexes of all paging frames PF in a paging cycle meet the set order, and each PF includes N s POs, the index of the first LP WUS sending opportunity is m, 0≤m≤(M-1).

[0275] It can be understood that, in this example, the PO index corresponding to the first LP WUS transmission opportunity corresponds to the PO in the PF of the PF index corresponding to the first LP WUS transmission opportunity.

[0276] In some embodiments, when every S LP WUS sending opportunities correspond to one PO in a paging cycle, the time interval between the second LP WUS sending opportunity and the corresponding PO is greater than or equal to the second duration; the second LP WUS sending opportunity is the last LP WUS sending opportunity in the time domain among the S LP WUS sending opportunities corresponding to the PO.

[0277] In one example, the second duration is configured by the network device 102 or defined by a protocol.

[0278] Step S4102 : The network device 102 sends an LP WUS to the user equipment 101 .

[0279] In some embodiments, the implementation of step S4102 can refer to the relevant implementations of steps S2102 to S2103 and S3102, and will not be repeated here.

[0280] In some embodiments, the network device 102 sends the LP WUS according to the LP WUS resource.

[0281] In some embodiments, the LP WUS includes indication information;

[0282] The indication information is used to indicate whether the user equipment 101 needs to wake up to monitor the PO corresponding to the LP WUS resource.

[0283] In some embodiments, the indication information includes a first information field, and the first information field is used to indicate whether the user equipment 101 or the user equipment group associated with the PO needs to be awakened.

[0284] In the first example, the first information field includes K bits, wherein the K bits correspond one-to-one to K POs corresponding to the LP WUS sending opportunities, and each bit is used to indicate whether the user equipment 101 associated with the corresponding PO needs to be awakened.

[0285] In the second example, the first information field includes K*L bits, where each of the K POs corresponding to the LP WUS sending opportunity corresponds to L bits, and each bit is used to indicate whether the user equipment group associated with the corresponding PO needs to be awakened, and L is the number of user equipment groups associated with each PO.

[0286] In the third example, the first information field includes K bits; wherein the K bits correspond one-to-one to K POs, and each bit is used to indicate whether a plurality of user equipment groups associated with the corresponding PO need to be awakened.

[0287] In the fourth example, the first information field includes one bit;

[0288] One bit corresponds to K POs, and one bit is used to indicate whether multiple user equipment groups associated with the K POs need to be awakened.

[0289] In some embodiments, the LP WUS instructs the user equipment to wake up.

[0290] When the LP WUS instructs the user equipment to wake up, the user equipment 101 may execute step S3103 .

[0291] In an example, the LP WUS is sent at any LP WUS sending opportunity among the S LP WUS sending opportunities corresponding to the PO, and the LP WUS indicates whether all or part of the associated user equipments 101 need to wake up.

[0292] Among the at least one user equipment 101 associated with the LP WUS sending opportunity with index s, the user equipment identifier UE ID of the user equipment 101 to be awakened satisfies:

[0293] Among them, 0≤s≤(S-1).

[0294] In some embodiments, the implementation of the method can also refer to the relevant implementation of steps S2105 and S3104, which will not be repeated here.

[0295] In the disclosed embodiment, network device 102 sends configuration information to user device 101 to inform it of the correspondence between LP WUS resources and POs. After receiving the configuration information, user device 101 can determine the LP WUS resource to monitor based on the time domain location of its corresponding PO and the correspondence indicated in the configuration information. This allows user device 101 to monitor the LP WUS in a timely manner at a reasonable location, allowing it to wake up in a timely manner even in an energy-saving state.

[0296] To facilitate understanding of the embodiments of the present disclosure, some specific examples are listed below:

[0297] In the disclosed embodiment, the base station configures an LP WUS cycle T, and configures M LP WUS transmission opportunities in one LP WUS cycle T. Each LP WUS transmission opportunity corresponds to one or more POs in a paging cycle. In this way, the UE can determine which one or more corresponding POs may have a paging DCI transmitted based on whether an LP WUS signal is transmitted at the LP WUS transmission opportunity. From the UE's perspective, the UE has already learned the index of the PO corresponding to it, and can thus determine the LP WUS timing it should monitor based on the correspondence between the LP WUS and the PO.

[0298] In some embodiments, the LP WUS period corresponds to the LP WUS sending period in the aforementioned embodiments.

[0299] Example 1:

[0300] The relationship between the network configuration LP-WUS resource and the PO it indicates;

[0301] The LP-WUS resource is the time domain, frequency domain or code domain resource sent by it;

[0302] The terminal obtains the LP-WUS indication information by reading the LP-WUS resource, and uses it to determine whether to monitor the associated PO in the future.

[0303] In some embodiments, the association relationship between the LP-WUS resource and the PO indicated by it corresponds to the corresponding relationship in the aforementioned embodiments.

[0304] Example 2:

[0305] Based on Example 1, the base station configures one LP-WUS resource corresponding to K POs, where K>=1;

[0306] for example:

[0307] The base station configures an LP WUS cycle T, and M (M>=1) LP WUS transmission opportunities are configured in one LP WUS cycle T. Each LP WUS transmission opportunity corresponds to K POs in one paging cycle, where K>=1.

[0308] Further:

[0309] The value of M*K is equal to the total number of POs in a paging cycle, that is, M*K=N*Ns, where N is the number of PFs in a paging cycle and Ns is the number of POs in a PF. In other words, M and / or K are factors of the total number of POs in a paging cycle.

[0310] The LP WUS sending timing index corresponds to numbers 0 to M-1. The corresponding relationship between the LP WUS sending timing index and the PF and / or PO index is as follows:

[0311] (1) If all POs in a paging cycle are numbered sequentially as PO 0 to PO N*Ns-1, then the K PO indices corresponding to the LP WUS transmission occasion m (0<=m<=M-1) are: mK~(m+1)*K-1;

[0312] (2) If all PFs in a paging cycle are numbered sequentially as PF 0 to PF N-1, and the POs contained in each PF are numbered sequentially as PO 0 to PO Ns-1, then

[0313] The PF index corresponding to the LP WUS sending opportunity m (0<=m<=M=1) is:

[0314] The PO index corresponding to the LP WUS sending time m is: PF index PO index mK-N in s * index PO index in

[0315] In this example, if the LP WUS sent at LP WUS sending timing m indicates wakeup, it will wake up the terminals corresponding to the K POs. After waking up, the terminals will monitor the POs and may also monitor system information.

[0316] Example 3:

[0317] Based on Example 1, the LP WUS may also carry indication information, such as a K-bit indication, for indicating whether the UE of each PO in the K POs corresponding to the LP WUS sending opportunity needs to be awakened.

[0318] for example:

[0319] The wakeup indicated by LP-WUS is for a specific PO. The network configuration sets the corresponding relationship between the establishment bit and the PO. For example, if there are 4 POs, there can be 4 bits, each used to wake up the corresponding PO monitoring.

[0320] Example 4:

[0321] Based on Example 1, the LP WUS may also carry indication information, such as a K*Lbit UE subgrouping indication, to indicate whether the L UE groups contained in each of the K POs corresponding to the LP WUS sending opportunity need to be awakened.

[0322] for example:

[0323] The LP-WUS wakeup instruction is for a specific group of a specific PO. The network configuration sets the corresponding bit to the specific group of a specific PO. For example, if there are 4 POs, each with 8 groups, there can be 4*8=32 bits, which are used to wake up the monitoring of the 8 groups on each PO.

[0324] Example 5:

[0325] Based on Example 1, if one LP-WUS resource corresponds to K POs, and all groups of K POs (K is greater than or equal to 1) need to be awakened, the following method can be used:

[0326] Mode 1: per PO indication, in which case the LP WUS carries K indication information; each indication information is used to indicate that all grouped users on the PO need to be woken up;

[0327] In this approach, each PO is divided into UE subgroups. For example, all UEs corresponding to each PO are divided into 8 UE subgroups. However, the UE subgroup division is not reflected in the LP WUS indication. For example, the LP WUS carries 4 bits, corresponding to a total of 4 POs. Each bit corresponds to all 8 subgroups of a PO.

[0328] Mode 2: K POs are combined to indicate that, in this case, the LP WUS carries one indication message to indicate that all the groups of the K POs associated with it need to be awakened.

[0329] Example 6:

[0330] Based on Example 1, the base station configures S LP-WUS resources corresponding to one PO; for example:

[0331] The base station configures an LP WUS cycle T, and M (M>1) LP WUS transmission opportunities are configured in one LP WUS cycle T. Each S LP WUS transmission opportunities corresponds to one PO in one paging cycle.

[0332] In this example, The value is equal to the total number of POs in a paging cycle, that is, M = S*N*Ns, where N is the number of PFs in a paging cycle and Ns is the number of POs in a PF. In other words, M is a multiple of the total number of POs in a paging cycle;

[0333] In this example, there are two cases:

[0334] In case 1, when an LP WUS is transmitted at any one of the S LP WUS transmission opportunities and the LP WUS indicates wake-up, all UEs corresponding to one PO corresponding to the S LP WUS transmission opportunities will be woken up.

[0335] Case 2: When an LP WUS is sent at any one of the S LP WUS sending opportunities and the LP WUS indicates wake-up, some UEs corresponding to the PO corresponding to the S LP WUS sending opportunities will be woken up. For example, the UE IDs of all UEs corresponding to the PO satisfy: The sth (0<=s<=S-1) LP WUS sending opportunity corresponds to waking up the UE ID in the PO and meets the condition UE.

[0336] In this example, the correspondence between the LP WUS sending opportunity index (numbered 0 to M-1) and the PF and / or PO index is as follows:

[0337] (1) If all POs in a paging cycle are numbered sequentially as PO 0 to PO N*Ns-1, then the PO index corresponding to LP WUS transmission occasion m (0<=m<=M-1) is:

[0338] (2) If all PFs in a paging cycle are numbered sequentially as PF 0 to PO N-1, and the POs contained in each PF are numbered sequentially as PO 0 to PO Ns-1, then

[0339] The PF index corresponding to the LP WUS sending opportunity m (0<=m<=M=1) is:

[0340] The PO index corresponding to the LP WUS sending time m is:

[0341] Example 7:

[0342] Based on Example 2, the time interval between the sending timing of the LP WUS and the most preceding PO in the time domain among the one or more POs associated with it is greater than or equal to T1. The value of T1 is defined by base station configuration or protocol.

[0343] Example 8:

[0344] Based on Example 6, the time interval between the last LP WUS transmission opportunity among the S LP WUS transmission opportunities and its associated PO is greater than or equal to T1. The value of T1 is configured by the base station or defined by a protocol.

[0345] Example 9:

[0346] In the above solution, the correspondence between the LP WUS resources and the PO is a correspondence between the index of the LP WUS resources in one LP WUS monitoring cycle and the index of the PO in one paging cycle.

[0347] After the UE is awakened by the LP WUS, the UE is not limited to monitoring the paging at the first PO corresponding to the UE after the interval T1, but may continue to monitor the paging at the PO corresponding to the UE in multiple subsequent paging cycles.

[0348] The maximum number of POs that a UE can monitor may be configured by the base station or defined by the protocol. If a UE does not hear a paging DCI or a paging message corresponding to itself within the maximum number of POs after being awakened by the LP WUS, the UE will go to sleep.

[0349] It can be understood that for a UE, it only corresponds to one PO in one paging cycle, so the multiple POs corresponding to the UE are in multiple paging cycles.
