[0141] The paging parameters are defined in the System Information Block Type 2 (SIB2). The network broadcasts these parameters periodically so that all terminals in the coverage area can receive them. Some of these parameters include the paging cycle, paging frame, paging subframe, paging group ID, and paging DRX. According to the configuration parameters broadcast by the system, the terminal detects the paging physical downlink control channel (PDCCH) on only one PO in a paging cycle. The terminal determines a paging frame (PF) in a paging cycle and determines a PO corresponding to this PF. According to the terminal's identifier UE ID, the system radio frame number (SFN) of the detected PF satisfies: (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N),

[0142] The index of the detected PO, Index(i_s), satisfies: i_s=floor(UE_ID / N)mod Ns,

[0143] Among them, PF offset: radio frame offset configured in system information; T: paging cycle; N: number of PFs in the paging cycle; UE ID: equal to 5G-S-TMSI mod 1024; Ns represents the number of POs in a PF, which can be 1, 2, and 4.

[0144] For paging information transmission, the paging information of a group of terminals is mapped to the same Point of View (PO). On this PO, the group of terminals monitors the PDCCH and the physical downlink shared channel (PDSCH) that carries the paging information. Whenever the base station sends paging information to at least one terminal in the group, the group will attempt to receive the PDSCH, which wastes energy. To save power, 3GPP introduced Paging Advance Indication (PEI). Specifically, the group of terminals mapped to the same PO is further divided into G paging subgroups. A PEI contains a bitmap indicating whether to wake up all POs of one or two PFs for the paging subgroup. The timing relationship between the PEI and the associated PF / PO is determined by system configuration parameters. The corresponding bit in the PEI is set to 1 only when the base station needs to send a paging message to at least one terminal in a paging subgroup. For a terminal, if its paging subgroup indication bit is not set, the terminal will no longer monitor the paging PDCCH and its scheduled PDSCH after receiving the PEI, thereby saving energy for the terminal.

[0145] To further reduce terminal power consumption, 3GPP is currently discussing a mechanism based on a low-power wake-up receiver (LP-WUR). In the power-saving state, the terminal can put the main radio (MR) into ultra-deep sleep and enable the LP-WUR to listen for a wake-up signal (LP-WUS) that supports low-power reception. When the LP-WUR detects the LP-WUS for this terminal, the terminal turns on the MR and performs normal transmission. This method greatly reduces the power consumption of the MR, and the power consumption of the LP-WUR is very low, thereby achieving greater power savings.

[0146] Based on LP-WUS, for idle terminals, after detecting the LP-WUS wakeup message, it takes a relatively long time (X ms) to wake up the mobile address reader (MR) and an additional time (Y) to complete the MR's time-frequency synchronization. The terminal can then detect the PDCCH and its scheduled PDSCH at the corresponding system-broadcasted paging location (PO) configured by the system. The latency of the terminal receiving the paging message depends on the wakeup delay (X), the synchronization time (Y), and the relative position of the LP-WUS and PO.

[0147] In related technologies, the paging cycle is generally configured to be relatively long, such as 1.28s, so as to provide a greater power saving effect for the terminal. The terminal only detects one PO in one paging cycle. The LP-WUS cycle can be set to be relatively short, so that it is possible to support a smaller waiting delay. However, there is a contradiction between the above two mechanisms. For example, even if the LP-WUS cycle of the terminal is set to be very short, it indicates that after the terminal wakes up and synchronizes, the terminal has to wait for a time of Z ms before it detects the timing position of the PO. The average value of the above delay Z is approximately equal to half of the paging cycle. In order to solve the above problem, the concept of dynamic PF / PO can be introduced. Based on the LP-WUS indication, dynamic PF / PO is allocated at the timing after the MR wakes up and synchronizes, which can maximize the reduction of the delay in the terminal receiving paging information, but this method requires additional paging resources.

[0148] Therefore, the present disclosure proposes a paging method and device, a communication system, a communication device, and a storage medium, which determine whether paging information needs to be detected based on the LP-WUS indication, reduce the paging delay without increasing the paging resource overhead, and achieve the effect of terminal power saving.

[0149] The method proposed in the present disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance and subsequent communication technologies (such as 6G, etc.).

[0169] FIG2 is a schematic diagram of an interaction of a paging method provided by an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a paging method, which can be executed by a communication system, such as the communication system 100 shown in FIG1 . The communication system includes network devices and terminals. The interaction method may include the following steps:

[0170] Step 2101: The network device broadcasts paging configuration information.

[0171] In some embodiments, the paging configuration information includes a paging cycle, for example, the paging cycle T=1.28s.

[0172] In some embodiments, the paging configuration information is used to determine a paging set, which includes N paging frames PF within a paging cycle, each PF including N s Optionally, in some embodiments, the N PFs or N*N s A PO can be called a "PF / PO configured by the system broadcast".

[0173] In some embodiments, the network device may broadcast the paging configuration information in different ways, such as using wireless resources, which is not limited in this disclosure.

[0174] In some embodiments, the bearer of the paging configuration information may be the system broadcast block SIB1, or may be SIBn, which is not limited in the present disclosure.

[0175] In some embodiments, through the paging configuration information broadcast by the network device, the terminal and the network device can determine a PO from the PF / PO configured by the system broadcast according to relevant technologies. The PO can be the traditional PO described in this disclosure or the target PO described in this disclosure. It can be understood that the target PO has a lower latency than the traditional PO.

[0176] In some embodiments, step 2101 is optional and may be omitted or replaced in different embodiments. Any method that can determine a PO with lower latency from the PF / PO configured by the system broadcast without requiring the network to configure additional paging resources falls within the scope of this disclosure.

[0177] Step 2102: The network device sends a first low power consumption wake-up signal LP-WUS to the terminal.

[0178] In some embodiments, the first low power consumption wake-up signal LP-WUS includes wake-up information for instructing the terminal to wake up the main receiver MR.

[0179] In some embodiments, the first low power consumption wake-up signal LP-WUS can wake up the main receiver of the terminal when the main receiver is in a sleep state, so as to achieve the purpose of power saving.

[0180] In some embodiments, for one LP-WUS period T lpwus, which may include multiple LP-WUSs, for example, M. Each LP-WUS can be used to indicate the awakening of one or more terminal groups. For example, if a network device sends an LP-WUS to at least one terminal in a terminal group, all terminals in the terminal group will be awakened. The terminal group can be a terminal group corresponding to a PO or a subgroup of a terminal group corresponding to a PO, and this disclosure is not limited to this.

[0181] In some embodiments, the first LP-WUS may be any one of M LP-WUSs. For example, the first LP-WUS may be an LP-WUS associated with the terminal or the terminal group or subgroup to which the terminal belongs. In other words, if the network device sends the first LP-WUS to at least one terminal in the terminal group or subgroup to which the terminal belongs, all terminals in the terminal group or subgroup are awakened.

[0182] In some embodiments, the first LP-WUS may include multiple indication bits, and indication bits at different positions may correspond to different terminals. For example, the bit position of the wake-up information instructing the terminal to wake up its MR in the first LP-WUS may be used to determine the target PO.

[0183] Step 2103: The network device and the terminal each determine a first delay based on the first LP-WUS.

[0184] In some embodiments, the first delay includes at least one of the following: the time required for the terminal to wake up the MR; the time required for the terminal to complete time and frequency synchronization with the MR; the time between the paging advance indication information PEI configured by the system broadcast and the PF / PO associated with the PEI; and the preparation time for the terminal to monitor the paging message.

[0185] Among them, the time required for the terminal to wake up MR may be the time required for the terminal to wake up MR after detecting the wake-up information of LP-WUS, and the time required for the terminal to complete time and frequency synchronization of MR may refer to the time required for the terminal to complete time and frequency synchronization of MR after waking up MR. Then the terminal can detect the PDCCH on the corresponding PO and its scheduled PDSCH, thereby receiving the paging message carried on the PDSCH.

[0186] Optionally, the duration between the paging advance indication information PEI configured by the system broadcast in the first delay and the PF / PO associated with the PEI means that, when PEI is applied, each PEI configured by the system broadcast can be associated with one or two PF / POs, that is, the delay between the position of each PEI and the position of its associated PF / PO.

[0187] The preparation time length of the terminal for monitoring the paging message may refer to other processing delays, which is not limited in the present disclosure.

[0188] In some embodiments, the first delay is used to determine a target PO. In other words, the target PO may be a PO that satisfies the first delay in the paging cycle, and may have a shorter waiting delay than a conventional PO.

[0189] Step 2104: The network device and the terminal respectively determine a first timing.

[0190] In some embodiments, the first timing is associated with a first LP-WUS.

[0191] In some embodiments, the first timing is any one of the following: the end time point of the last symbol of the channel of the first LP-WUS; the end time point of the last time slot of the first LP-WUS; the end time point of the last subframe of the first LP-WUS; and the end time point of the last wireless frame of the first LP-WUS.

[0192] In some embodiments, the first timing is the end time point of the last symbol of the channel of the second LP-WUS, and the second LP-WUS is the last LP-WUS of the LP-WUS period in which the first LP-WUS is located; the end time point of the last time slot of the second LP-WUS; the end time point of the last subframe of the second LP-WUS; the end time point of the last radio frame of the second LP-WUS; and the end time point of the LP-WUS period in which the first LP-WUS is located.

[0193] In some embodiments, the name of the first timing is not limited and can be "start time", "first time", etc.

[0194] In the embodiment of the present disclosure, the manner in which the terminal determines the first timing is the same as the manner in which the network device determines the first timing, and thus will not be described in detail again.

[0195] Step 2105: The network device and the terminal respectively determine the target PO.

[0196] In some embodiments, the network device determines a PO that meets a preset condition in a paging cycle as a target PO.

[0197] In some embodiments, the target PO is a PO used by the network device to send a paging message to the terminal.

[0198] In some embodiments, the target PO is one of the POs configured by system messages (i.e., the "PO configured by system broadcast" or "paging set" described above). In some embodiments, the preset condition may be that the interval between the second timing associated with the target PO and the first timing is greater than or equal to the first delay. In other words, the target PO may be a PO that meets the first delay, or a PO after the first delay.

[0199] The following describes the process of determining the target PO in detail through an example.

[0200] Example 1:

[0201] In some embodiments, the target PO is the first PO after the first time delay.

[0202] In some embodiments, the second timing includes any one of the following: the starting time point of the first symbol of the first PO; the starting time point of the first time slot of the first PO; the starting time point of the first subframe of the first PO; the starting time point of the first wireless frame of the first PO.

[0203] In some embodiments, the target PO is a PO in the first PF after the first time delay.

[0204] In some embodiments, the second timing is a start time point of the first PF.

[0205] In some embodiments, determining the target PO from the first PF may be determining the target PO according to the number of POs included in the first PF and the identifier of the terminal.

[0206] For example, the target PO in the first PF is calculated according to i_s=floor(UE_ID / N) mod Ns.

[0207] In some embodiments, determining the target PO from the first PF may be determining the first PO of the first PF as the target PO.

[0208] For example, the target PO index in the first PF is i_s=0.

[0209] In some embodiments, determining the target PO from the first PF may be determining the target PO from the first PF according to a bit position in the first LP-WUS of wake-up information instructing the terminal to wake up the MR.

[0210] In some embodiments, determining the target PO according to the bit position in the first LP-WUS of the wake-up information indicating the terminal to wake up the MR includes: determining the PO where the bit position is located in the first PF according to the bit position in the first LP-WUS of the wake-up information indicating the terminal to wake up the MR, and the number of multiple paging subgroups included in each PO in the paging cycle; and determining the PO as the target PO.

[0211] For example, assuming that each PO is divided into G paging subgroups, the PO index of the k-th bitmap of the LP-WUS information can be For example, a PO is divided into 4 subgroups, and a PF has 4 POs. If the 5th bit of the first LP-WUP indicates that a certain terminal wakes up the MR, it can be determined that the index of the target PO corresponding to the terminal is 1, that is, the second PO.

[0212] In some embodiments, determining a PO that meets a preset condition in a paging cycle as a target PO includes: determining a second PO as the target PO, the second PO being one of the first n POs after the first time delay, Among them, T lpwus is the LP-WUS cycle, T is the paging cycle, N is the number of PFs included in the paging cycle, N s The number of POs included in each PF.

[0213] In some embodiments, the second timing can be any one of the following: the starting time point of the first symbol of the first PO among the first n POs; the starting time point of the first time slot of the first PO among the first n POs; the starting time point of the first subframe of the first PO among the first n POs; the starting time point of the first wireless frame of the first PO among the first n POs.

[0214] In some embodiments, the second PO may be the first PO among the first n POs.

[0215] In some embodiments, the second PO may be a PO determined from the first n POs according to n and the identification of the terminal.

[0216] For example, for a LP-WUS, its associated PO is the first n POs in the PO set configured by the system broadcast that meet the delay D, where n is greater than or equal to 1. For example, For a terminal detecting the LP-WUS, the index of a PO detected within the n POs may be UE_ID mod n.

[0217] In some embodiments, the second PO may be a PO determined from the first n POs according to the bit position of the wake-up information instructing the terminal to wake up the MR in the first LP-WUS and the number of paging subgroups included in each PO in the paging cycle.

[0218] For example, assuming that each PO is divided into G paging subgroups, the PO index of the k-th bitmap of the LP-WUS information can be

[0219] In some embodiments, determining the PO that meets the preset conditions in the paging cycle as the target PO may be determining the target PO from the first m PFs after the first time delay. Among them, T lpwusis the LP-WUS cycle, T is the paging cycle, and N is the number of PFs included in the paging cycle.

[0220] In some embodiments, the second timing may be a start time point of the first PF among the first m PFs.

[0221] In some embodiments, determining the target PO from the first m PFs after the first delay may be determining a second PF, where the second PF is the first PF among the first m PFs after the first delay, or the second PF is a PF determined from the first m PFs based on m and the terminal identifier, and the target PO is determined from the second PF based on the number of POs included in the second PF, the number of PFs included in the paging cycle, and the terminal identifier.

[0222] For example, the second PF is calculated according to UE_ID mod m, and the target PO is calculated according to i_s=floor(UE_ID / N) mod Ns.

[0223] In some embodiments, determining the target PO from the first m PFs after the first delay can be based on the bit position of the wake-up information indicating the terminal to wake up MR in the first LP-WUS, and the number of multiple paging subgroups included in each PO in the paging cycle, and determining the PO where the bit position is located in the first m PFs as the target PO.

[0224] For example, assuming that each PO is divided into G paging subgroups, the PO index of the k-th bitmap of the LP-WUS information can be

[0225] Example 2:

[0226] In some embodiments, determining the PO that meets the preset conditions in the paging cycle as the target PO can be to determine the target PO from the first PF group, wherein the first LP-WUS is associated with the first PF group, the first PF group is the first PF group after the first delay, the paging cycle includes N / P PF groups, and each PF group includes P PFs.

[0227] In some embodiments, the second timing may be a start time point of the first PF in the first PF group.

[0228] In some embodiments, determining the target PO from the first PF group may be determining a third PF, where the third PF is the first PF in the first PF group, or the third PF is a PF determined in the first PF group based on the P and the terminal identifier; determining the target PO from the third PF based on the number of POs included in the third PF, the number of PFs included in the paging cycle, and the terminal identifier.

[0229] For example, the third PF is calculated according to UE_ID mod P, and the target PO is calculated according to i_s=floor(UE_ID / N) mod Ns; or the third PF is calculated according to mod(UE_ID, P), and the target PO is calculated according to Calculate target PO.

[0230] In some embodiments, determining the target PO from the first PF group may be determining the target PO from P PFs in the first PF group according to P, the number of POs included in each PF, and the identifier of the terminal.

[0231] For example, the target PO may be calculated according to UE_ID mod (P*Ns).

[0232] Example 3:

[0233] In some embodiments, the target PO may be determined from Q PFs after the first delay, where the LP-WUS cycle in which the first LP-WUS is located includes M LP-WUSs, and the M LP-WUSs are associated with Q PFs in the paging set, where Q = N·T lpwus / T, where T lpwus is the LP-WUS cycle, T is the paging cycle; or, the target PO is determined from the first group of PFs after the first time delay, wherein the paging cycle includes N / Q PF groups, and each PF group includes Q PFs.

[0234] In some embodiments, the second timing may be a start time point of the first PF among the Q PFs after the first time delay.

[0235] In some embodiments, determining the target PO from the Q PFs after the first delay may be determining the target PO from the Q PFs after the first delay based on at least one of the index, Q, M, and Ns of the first LP-WUS in the LP-WUS cycle.

[0236] For example, the index of the first LP-WUS in the LP-WUS cycle is m, m=0, 1, ... M-1, and the index of the target PO is Or m mod(Q*Ns).

[0237] In some embodiments, determining the target PO from the Q PFs after the first delay can be determining the fourth PF from the Q PFs after the first delay based on the index, Q, and M of the first LP-WUS in the LP-WUS cycle, and determining the target PO from the fourth PF based on the terminal's identifier, N, and Ns.

[0238] For example, the index of the fourth PF is Or m mod Q, the index of the target PO is i_s=floor(UE_ID / N) mod Ns.

[0239] In the above embodiment, the PO associated with any one of the M LP-WUSs is a PO in the Q PFs, multiple POs in the same PF are associated with different LP-WUSs, and terminals configured with the same LP-WUS are associated with the same PO in the Q PFs.

[0240] In some embodiments, determining the target PO from the Q PFs after the first delay can be determining the fifth PF from the Q PFs after the first delay based on the index, Q, and M of the first LP-WUS in the LP-WUS cycle, and determining the target PO from the fifth PF based on the terminal's identifier, N, and Ns.

[0241] For example, the index of the first LP-WUS in the LP-WUS cycle is m, and the index of the fifth PF is Or m mod Q, the index of the target PO is i_s=floor(UE_ID / N) mod Ns.

[0242] In some embodiments, determining the target PO from the Q PFs after the first delay can be based on the bit position in the first LP-WUS of the wake-up information indicating that the terminal wakes up the MR, and the number of multiple paging subgroups included in each PO in the paging cycle, to determine the target PO from the Q PFs after the first delay.

[0243] For example, assuming that each PO is divided into G paging subgroups, the k-th bit of the LP-WUS information is mapped to the PO index of its associated PF can be

[0244] In the above embodiment, the POs associated with any one of the M LP-WUSs are multiple POs of one of the Q PFs, and terminals configured with the same LP-WUS are associated with the same PF of the Q PFs.

[0245] In some embodiments, determining the target PO from the Q PFs after the first delay can be determining the index of the starting PO in the Q PFs based on the index, Q, M, and Ns of the first LP-WUS in the LP-WUS cycle; and determining the target PO based on the index, Q, and Ns of the starting PO.

[0246] For example, for one LP-WUS, its associated PO is n POs of Q PFs, the index of the first LP-WUS in the LP-WUS cycle is m, and the index of the starting PO of the n POs in the Q PFs is Or k=m mod(Q*Ns), the index of n POs is mod(k+i,Q·N s )i=0,1,…n-1.

[0247] In some embodiments, determining the target PO from the Q PFs after the first delay can be determining the target PO from the Q PFs based on the bit position in the first LP-WUS of the wake-up information indicating that the terminal wakes up the MR, and the number of multiple paging subgroups included in each PO in the paging cycle.

[0248] For example, assuming that each PO is divided into G paging subgroups, the k-th bit of the LP-WUS information is mapped to the PO index in its associated Q PFs can be

[0249] In the above embodiment, the PO associated with any one of the M LP-WUS is x POs in the Q PFs, 1≤x≤Q·N s .

[0250] In some embodiments, determining the target PO from the Q PFs after the first delay can be determining the index of the starting PF in the Q PFs based on the index, Q, and M of the first LP-WUS in the LP-WUS cycle; and determining the index of y PFs in the Q PFs based on the index, Q of the starting PF; and determining the target PO from the y PFs based on the terminal's identifier, N, and Ns.

[0251] For example, the index of the first LP-WUS in the LP-WUS cycle is m, and the index of the starting PF is Or k=m mod Q, the index of y PFs is mod(k+i,Q)i=0,1,…y-1, and the index of the target PO is i_s=floor(UE_ID / N)mod Ns.

[0252] In some embodiments, determining the target PO from the Q PFs after the first delay can be determining the target PO from the Q PFs based on the bit position in the first LP-WUS of the wake-up information indicating that the terminal wakes up the MR, and the number of multiple paging subgroups included in each PO in the paging cycle.

[0253] For example, assuming that each PO is divided into G paging subgroups, the k-th bit of the LP-WUS information is mapped to the PO index in its associated Q PFs can be

[0254] In the above embodiment, the PF associated with any one of the M LP-WUSs is y PFs among the Q PFs, where 1≤y≤Q.

[0255] Example 4:

[0256] In some embodiments, determining the target PO may include determining a PO in a first PF group after a first time delay as the target PO, wherein M LP-WUSs are associated with the first PF group, the first PF group is the first PF group after the first time delay, the paging cycle includes N / P PF groups, and each PF group includes P PFs.

[0257] For example, within the PF / PO set configured by the system broadcast, PFs in a paging cycle are equally divided into N / P groups, with each group containing P adjacent PFs. For example, a PEI indicates the paging subgroup information for P PFs. The M LP-WUSs in an LP-WUS cycle can be associated with the first group of PFs that meets the delay D.

[0258] In some embodiments, the second timing is a start time point of the first PF in the first PF group.

[0259] In some embodiments, determining the target PO from the first PF group after the first delay can be determining the sixth PF in the first PF group based on Q and the terminal identifier, and determining the target PO from the sixth PF based on Ns, N, and the terminal identifier.

[0260] For example, the index of the sixth PF is UE_ID mod P, and the index of the target PO is i_s=floor(UE_ID / N) mod Ns.

[0261] In some embodiments, determining the target PO from the first PF group after the first delay can be determining the seventh PF in the first PF group based on the modulus of P and the terminal identifier, and determining the target PO from the seventh PF based on Ns, P, and the terminal identifier.

[0262] For example, the index of the seventh PF is mod(UE_ID,P), and the index of the target PO is

[0263] In some embodiments, determining the target PO from the first PF group after the first time delay may be determining the target PO from the PFs in the first PF group according to P, Ns, and the identifier of the terminal.

[0264] For example, the index of the target PO among all POs of P PFs is UE_ID mod (P*Ns).

[0265] In some embodiments, determining the target PO from the first PF group after the first delay can be determining the starting PF of P PFs based on P, the number of LP-WUS included in the LP-WUS cycle, and determining the target PO from the starting PF based on Ns, N, and the terminal identifier.

[0266] For example, the index of the starting PF is Or m mod P, then the index of the target PO is i_s=floor(UE_ID / N) mod Ns.

[0267] In some embodiments, determining the target PO from the first PF group after the first delay can be determining the target PO from P PFs based on the bit position in the first LP-WUS of the wake-up information indicating that the terminal wakes up the MR, and the number of multiple paging subgroups included in each PO in the paging cycle.

[0268] For example, assuming that each PO is divided into G paging subgroups, the k-th bit of the LP-WUS information is mapped to the PO index of its associated PF can be

[0269] Example 5:

[0270] In some embodiments, the target PO may be determined from a first short cycle, where the paging cycle includes K short cycles, each short cycle includes W PFs, where W=N / K, and the first LP-WUS is associated with a PF or PO in the first short cycle, where the first short cycle is the first short cycle after the first delay.

[0271] For example, a short paging cycle is introduced into the PF / PO set configured by the system broadcast. A PF / PO of a short paging cycle that satisfies the delay D is associated with an LP-WUS. The paging cycle is T, and the number of PFs in a paging cycle is N. The paging cycle T can be divided into K short paging cycles T / K, and each short paging cycle T / K includes (P=N) / K PFs. Each PF still includes Ns POs according to the system broadcast configuration. When PEI is configured, the PEI in each paging cycle T is also divided into K short paging cycles T / K accordingly. The association relationship between PEI and PF / PO remains unchanged. Define the PF / PO mapped to each UE ID in the short paging cycle. Accordingly, the number of PF / POs of the terminal within time T increases to K. For a terminal that detects an LP-WUS, its associated PF / PO is the most recent PF / PO that satisfies the delay D and is allocated to this terminal according to the above short paging cycle.

[0272] In some embodiments, the second timing can be any one of the following: the starting time point of the first symbol of the first PO, the first PO is the first PO after the first delay; the starting time point of the first time slot of the first PO; the starting time point of the first subframe of the first PO; the starting time point of the first wireless frame of the first PO; the starting time point of the first PF, the first PF is the first PF after the first delay; the starting time point of the first symbol of the PEI associated with the first PF; the starting time point of the first time slot of the PEI associated with the first PF; the starting time point of the first subframe of the PEI associated with the first PF; the starting time point of the first wireless frame of the PEI associated with the first PF; the starting time point of the short paging cycle where the first PO is located; the starting time point of the short paging cycle where the first PF is located.

[0273] In some embodiments, determining the target PO from the first short cycle can be based on the identification of W and the terminal, determining the index of the eighth PF in the first short cycle, the eighth PF is the PF associated with the first LP-WUS in the first short cycle, and determining the target PO from the eighth PF.

[0274] For example, the index of the eighth PF is UE_ID mod P, and the index of the target PO is i_s=floor(UE_ID / N) mod Ns; or the index of the eighth PF is mod(UE_ID, P), and the index of the target PO is

[0275] In some embodiments, determining the target PO from the first short cycle may be determining the target PO in the first short cycle according to W, the terminal identifier, and Ns. For example, the index of the target PO is UE_ID mod (P*Ns).

[0276] In the above embodiments, the target PO is determined by different methods, so that the network device can send a paging message to the terminal through the determined target PO, thereby reducing the paging delay without increasing paging resources and achieving the purpose of power saving.

[0277] In the embodiment of the present disclosure, the way in which the terminal determines the target PO is the same as the way in which the network device determines the target PO, which will not be repeated here.

[0278] In step 2106, the network device and the terminal respectively determine the traditional PO.

[0279] In some embodiments, the terminal receives paging configuration information broadcast by the network device and determines the traditional PO according to the paging configuration information.

[0280] In some embodiments, the network device determines the PF where the traditional PO is located based on the terminal's identifier, N, paging cycle, and radio frame offset, and then determines the PF where the traditional PO is located based on the terminal's identifier, N, and Ns Identify traditional PO.

[0281] For example, according to the terminal identifier UEID, the system radio frame number (SFN) of the PF where the traditional PO is located satisfies:

[0282] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0283] The index of traditional PO (i_s) satisfies: i_s = floor (UE_ID / N) mod Ns,

[0284] PF offset: radio frame offset configured in system information;

[0285] T: paging cycle;

[0286] N: the number of PFs in the paging cycle;

[0287] UE ID: equal to 5G-S-TMSI mod 1024

[0288] Ns represents the number of POs in a PF, which can be 1, 2 or 4.

[0289] In some embodiments, the traditional PO is determined to serve as an optional solution for the embodiment of the method, that is, the paging message can be sent on the target PO or on the traditional PO.

[0290] For example, the terminal described in the present disclosure can be a terminal using LP-WUS or a terminal not using LP-WUS. For the terminal not using LP-WUS, the network device needs to send a paging message to the terminal not using LP-WUS on a traditional PO; for the terminal using LP-WUS, the network device can send a paging message to the terminal on a target PO. Optionally, if the network device fails to send a paging message to the terminal through the target PO (for example, the terminal does not respond to the paging), the network device can send a paging message to the terminal on a traditional PO. This disclosure does not limit this.

[0291] In the embodiment of the present disclosure, the way in which the terminal determines the traditional PO is the same as the way in which the network device determines the traditional PO, which will not be repeated here.

[0292] In some embodiments, step 2106 is an optional step and may be omitted or replaced in different embodiments.

[0293] Step 2107: The network device sends a paging message to the terminal on the target PO.

[0294] In some embodiments, the network device sends a paging message to the target PO of the terminal via the target PO.

[0295] In the embodiment of the present disclosure, "the network device sends a paging message to the terminal" may mean that the network device sends a PDSCH carrying the paging message scheduled by the PDCCH to the terminal. Correspondingly, the terminal receives the PDSCH carrying the paging message scheduled by the PDCCH.

[0296] In some embodiments, the type of paging message is not limited.

[0297] In step 2108, the network device sends a paging message to the terminal on the traditional PO.

[0298] In some embodiments, the network device determines a traditional PO based on the broadcast paging configuration information, and sends a paging message to the terminal through the traditional PO, which can be used as an optional solution of this method.

[0299] In some embodiments, step 2108 is optional and may be omitted or replaced in different embodiments. For example, step 2108 may be performed when step 2107 fails (e.g., the terminal does not respond to the paging message sent by the network device at the target PO, in other words, the terminal fails to receive the paging message at the target PO).

[0300] The paging method involved in the embodiment of the present disclosure may include at least one of steps 2101 to 2108. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and so on, but the present invention is not limited thereto.

[0301] In some embodiments, step 2101, step 2102, step 2103, and step 2104 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0367] Figures 6A and 6B are schematic diagrams of determining a target PO according to an embodiment of the present disclosure. Figure 6A shows a process for directly determining a target PO based on LP-WUS, and Figure 6B shows a process for determining a target PO based on LP-WUS and paging advance indication information (PEI). The method for determining a target PO includes the following five embodiments:

[0368] Example 1:

[0369] A PF / PO associated with an LP-WUS can be one of the most recent system-broadcasted PF / POs that meets the delay D, thereby reducing the paging delay. Meeting the delay D can mean that the interval from timing A to timing B is greater than or equal to D. The definition of timing B depends on the specific LP-WUS-associated PF / PO method, and timing A can be defined as one of the following:

[0370] End time point of LP-WUS;

[0371] The end time of the last time slot of LP-WUS;

[0372] The end time of the last subframe of LP-WUS;

[0373] The end time of the last radio frame of LP-WUS;

[0374] The end time point of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0375] The end time point of the last time slot of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0376] The end time point of the last subframe of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0377] The end time point of the last radio frame of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0378] The end time point of the LP-WUS cycle in which the LP-WUS is located.

[0379] Method 1: For an LP-WUS, its associated PO is the first PO in the PF / PO set configured by the system broadcast that meets the delay D. Assuming a PF includes multiple POs, these POs can be associated with different LP-WUSs. Terminals configured with the same LP-WUS are associated with the same PO in the PF / PO set configured by the system broadcast.

[0380] Timing B can be defined as one of the following:

[0381] The starting time of the first PO that meets the delay D;

[0382] The starting time of the first PO that meets the delay D;

[0383] The starting time of the first PO subframe that meets the delay D;

[0384] The start time of the first PO radio frame that meets the delay D;

[0385] The second method: For an LP-WUS, the associated PF is the first PF in the PF set configured by the system broadcast that meets the delay D. Terminals configured with the same LP-WUS are associated with the same PF in the PF / PO set configured by the system broadcast.

[0386] Timing B can refer to one of the following definitions:

[0387] The starting time of the first PF that meets the delay D;

[0388] The start time of the first PF that meets the delay D;

[0389] The starting time of the first subframe of the PF that meets the delay D;

[0390] The starting time point of the first radio frame of the PF that meets the delay D.

[0391] The method of determining PO can be any of the following:

[0392] For a terminal detecting the LP-WUS, the PO index detected by the terminal in this associated PF is still i_s=floor(UE_ID / N)mod Ns;

[0393] Alternatively, for a terminal detecting the LP-WUS, the PO index i_s detected by the terminal in this associated PF is = 0;

[0394] Alternatively, for a terminal detecting the LP-WUS, the PO index detected by the terminal within the associated PF may be determined based on the position of the wake-up information bit of the terminal in the wake-up information carried by the LP-WUS. For example, assuming that each PO is divided into G paging subgroups, the PO index mapped to the kth bit of the LP-WUS information may be

[0395] The third method: For a LP-WUS, its associated PO is the first n POs in the PO set configured by the system broadcast that meet the delay D, where n is greater than or equal to 1. For example, For a terminal detecting the LP-WUS, it detects one PO among the n POs.

[0396] Timing B can be defined as one of the following:

[0397] The starting time of the first PO among the first n POs that meet the delay D;

[0398] The starting time of the first PO among the first n POs that meet the delay D;

[0399] The starting time of the subframe of the first PO among the first n POs that meet the delay D;

[0400] The starting time point of the wireless frame of the first PO among the first n POs that meet the delay D.

[0401] The method of determining PO can be any of the following:

[0402] For a terminal detecting the LP-WUS, the index of the detected PO in the n POs may be UE_ID mod n;

[0403] Alternatively, for a terminal detecting the LP-WUS, the PO index detected by the terminal within the n POs may be determined based on the position of the wake-up information bit of the terminal in the wake-up information carried by the LP-WUS. For example, assuming that each PO is divided into G paging subgroups, the PO index mapped to the kth bit of the LP-WUS information may be

[0404] The fourth method: For a LP-WUS, its associated PF is the first n PFs in the PF set configured by the system broadcast that meet the delay D, where For example, n = 2. For a terminal detecting the LP-WUS, it detects a PO of a PF within the n PFs.

[0405] Timing B can be defined as one of the following:

[0406] The starting time of the first PF among the first n PFs that meet the delay D;

[0407] The starting time of the first PF's starting time slot among the first n PFs that meet the delay D;

[0408] The starting time of the subframe of the first PF among the first n PFs that meet the delay D;

[0409] The starting time point of the radio frame of the first PF among the first n PFs that meet the delay D.

[0410] The method of determining PO can be any of the following:

[0411] For example, for a terminal detecting the LP-WUS, the index of the detected PF in the above n PFs may be UE_ID mod n, and the detected PO index in this PF is still i_s=floor(UE_ID / N) mod Ns;

[0412] Alternatively, for a terminal detecting the LP-WUS, the PO index of the terminal within the n PFs may be determined based on the position of the wake-up information bit of the terminal in the wake-up information carried by the LP-WUS. For example, assuming that each PO is divided into G paging subgroups, the PO index mapped to the kth bit of the LP-WUS information may be

[0413] Example 2:

[0414] Within the PF / PO set configured by the system broadcast, PFs in a paging cycle are equally divided into N / P groups, each containing P adjacent PFs. For example, a PEI indicates the paging subgroup information for P PFs. The PF / PO associated with an LP-WUS may be the first group of PFs that meets delay D. Meeting delay D may mean that the interval from timer A to timer B is greater than or equal to D.

[0415] Timing A can be defined as one of the following:

[0416] End time point of LP-WUS;

[0417] The end time of the last time slot of LP-WUS;

[0418] The end time of the last subframe of LP-WUS;

[0419] The end time of the last radio frame of LP-WUS;

[0420] The end time point of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0421] The end time point of the last time slot of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0422] The end time point of the last subframe of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0423] The end time point of the last radio frame of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0424] The end time point of the LP-WUS cycle in which the LP-WUS is located.

[0425] Timing B can be any of the following:

[0426] The starting time of the first PF among P PFs;

[0427] The starting time of the first time slot of the first PF among the P PFs;

[0428] The starting time point of the first subframe of the first PF among the P PFs;

[0429] The starting time point of the first radio frame of the first PF among the P PFs.

[0430] The delay D may include the above-mentioned wake-up delay X, synchronization time Y, the delay from the PEI configured by the system broadcast to the associated PF / PO, and other processing delays. Accordingly, after receiving the wake-up information from the LP-WUS, the terminal may first detect the PEI to further determine whether it is necessary to detect the paging information. When the PEI indicates all the paging subgroups of the terminal, the terminal further detects the paging information. Alternatively, the delay D may include the above-mentioned wake-up delay X, synchronization time Y, and other processing delays. Accordingly, after receiving the wake-up information from the LP-WUS, the terminal may further detect the paging information directly at the corresponding PO.

[0431] The method of determining PO can be any of the following:

[0432] For a terminal detecting the above LP-WUS, the following method can also be used to determine its associated PF / PO. For a terminal detecting the above LP-WUS, the index of the detected PF in the P PFs can be UE_ID mod P, and the index of the detected PO in this PF is still i_s = floor (UE_ID / N) mod Ns;

[0433] Alternatively, for a terminal detecting the above LP-WUS, the index of the detected PF in the P PFs may be mod(UE_ID, P), and the detected PO index in this PF may be

[0434] Alternatively, for a terminal detecting the above-mentioned LP-WUS, the index of the detected PO in all POs of the P PFs may be UE_ID mod (P*Ns).

[0435] Example 3:

[0436] The M LP-WUSs in one LP-WUS cycle can be associated with the P neighboring PFs in the PF / PO set configured by the system broadcast. For example, P = N·T lpwus / T. P is the number of PFs in the time period corresponding to the LP-WUS cycle on the above PF / PO set. The P PFs can be the first P PFs in the PF set configured by system broadcast that meet the delay D. Alternatively, within the PF / PO set configured by system broadcast, the PFs in a paging cycle are equally divided into T / T lpwus Each group includes P adjacent PFs. The P PFs may be the first group of PFs in the PF set configured by the system broadcast that meets the delay D. For example, the PF grouping may be based on a radio frame with an SFN of 0 as the starting point of a group of PFs. The M LP-WUSs within an LP-WUS cycle may be evenly associated with the P PFs.

[0437] The above-mentioned satisfaction of the delay D may mean that the interval from timing A to timing B is greater than or equal to D. Timing A can be defined as one of the following:

[0438] The end time point of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

[0439] The end time point of the last time slot of the last LP-WUS in the LP-WUS cycle in which the LP-WUS is located;

When the PEI indicates all the paging subgroups of the terminal, the terminal further detects the paging information. Alternatively, the delay D may include the above-mentioned wake-up delay X, synchronization time Y, and other processing delays.

Each PF still includes Ns POs according to the system broadcast configuration. When PEI is configured, the PEI in each paging cycle T is also divided into K short paging cycles T / K accordingly. The association relationship between PEI and PF / PO remains unchanged. Define the PF / PO mapped by each UE ID in the short paging cycle. Accordingly, the number of PF / POs of the terminal within time T increases to K.
