[0111] 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),

[0112] The index of the detected PO, Index(i_s), satisfies: i_s=floor(UE_ID / N)mod Ns,

[0113] 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.

[0114] 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.

[0115] 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.

[0116] Based on LP-WUS, for idle terminals, after detecting the wake-up information from LP-WUS, it takes a relatively long time (X ms) for the terminal to wake up the MR, and an additional time (Y) is required to complete the time-frequency synchronization of the MR. The terminal can then further detect the PEI PDCCH to further determine whether there may be paging information sent to it. When the PEI indicates the paging subgroup of the terminal, the terminal detects the PDCCH on the corresponding PO and its scheduled PDSCH. The delay in the terminal receiving the paging information depends on the wake-up delay (X), the synchronization time (Y), and the relative position of the LP-WUS and the PO.

[0117] 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.

[0118] Therefore, the present disclosure proposes a paging method and device, a communication system, a communication device, and a storage medium, which determine whether it is necessary to wake up the MR and detect the PEI based on the LP-WUS indication, reduce the paging delay without increasing the paging resource overhead, and achieve the terminal power saving effect.

[0119] 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.).

[0138] FIG2 is a schematic diagram of an interaction of a paging method proposed in an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a paging method that 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:

[0139] Step 2101: The network device broadcasts paging configuration information.

[0140] In some embodiments, the paging configuration information includes a paging cycle, for example, the paging cycle T=1.28s.

[0141] In some embodiments, the paging configuration information is used to determine a paging set and a PEI set. The paging set includes N paging frames PF within a paging cycle. Each PF includes N s A PO, a PEI set includes multiple PEIs, and each PEI is associated with one or two PFs.

[0142] 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.

[0143] 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.

[0144] Step 2102: The network device sends a first low power consumption wake-up signal LP-WUS to the terminal.

[0145] 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.

[0146] 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.

[0147] In some embodiments, for one LP-WUS period T lpwus , which may include multiple LP-WUSs, for example, M. Each LP-WUS may 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 may 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 thereto.

[0148] 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.

[0149] 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 PEI.

[0150] In some embodiments, the network device sending the first low power consumption wake-up signal LP-WUS to the terminal includes: sending the first LP-WUS to at least one terminal in the terminal group to which the terminal belongs according to a preset grouping rule.

[0151] For example, the first LP-WUS information may include one or more bits, each bit associated with multiple terminals, indicating that at least one of the multiple terminals should be woken up. A terminal may detect the wakeup information based on only one bit of the first LP-WUS information. For a terminal detecting the first LP-WUS, the terminal may detect the PEI associated with the first LP-WUS only when the first LP-WUS includes wakeup indication information corresponding to the terminal.

[0152] In some embodiments, the preset grouping rule may be: the terminal group is a group of terminals corresponding to the PO associated with the terminal, and one bit of the first LP-WUS indicates the wake-up information of all terminals in a terminal group in the group.

[0153] For example, all terminals associated with a PO configured by the system broadcast are mapped to the same bit of an LP-WUS. A single bit of the LP-WUS indicates wake-up information for all terminals associated with one or more POs configured by the system broadcast. The LP-WUS does not indicate paging subgroup information. For example, if a PO is associated with 64 terminals, then the terminal group here is 64 terminals. After the network sends the LP-WUS, all 64 terminals are awakened.

[0154] In some embodiments, the preset grouping rule may be: the terminal group is a subgroup in a group of terminals corresponding to the PO associated with the terminal, one bit of the first LP-WUS indicates the wake-up information of all terminals in the subgroup, and the subgroup is the same as the paging subgroup divided by PEI.

[0155] For example, all terminals associated with a paging subgroup of a PO configured by the system broadcast are mapped to the same bit of an LP-WUS. One bit of the LP-WUS only indicates the wake-up information of all terminals associated with a paging subgroup of the above-mentioned PO. According to the grouping of the LP-WUS, a subgroup of users is awakened, and this subgroup receives PEI. The grouping method of the LP-WUS is consistent with the grouping method of the PEI. For example, assuming that a PO is associated with 64 terminals, the PEI divides it into 8 groups, each with 8 terminals. The terminal group here is the subgroup to which the terminal belongs. After the network sends the LP-WUS, the 8 terminals in the subgroup to which the terminal belongs are awakened.

[0156] In some embodiments, the preset grouping rule may be: the terminal group is a subgroup in a group of terminals corresponding to the PO associated with the terminal, one bit of the first LP-WUS indicates the wake-up information of all terminals in the subgroup, and the subgroup is different from the paging subgroup divided by PEI.

[0157] For example, all terminals associated with a PO configured by system broadcast are mapped to multiple bits of an LP-WUS. All terminals associated with a paging subgroup of a PO configured by system broadcast are mapped to multiple bits. The multiple bits of LP-WUS only indicate the wake-up information of all terminals associated with the above-mentioned PO. According to the grouping of LP-WUS and the grouping of PEI, the intersection users are awakened and receive PEI. The grouping method of LP-WUS is different from that of PEI. For example, assuming that a PO is associated with 64 terminals, PEI divides them into 8 groups, each with 8 terminals (8 rows, 8 terminals per row), and LP-WUS divides the 64 terminals into 4 groups from another dimension, each with 16 terminals (4 columns, 16 terminals per column). The terminal group here is the intersection of the subgroups to which the terminal belongs. After the network sends LP-WUS, the two terminals of the subgroup to which the terminal belongs are awakened.

[0158] Step 2103: The network device and the terminal each determine a first delay based on the first LP-WUS.

[0159] In some embodiments, the first delay may be 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; and the preparation time for the terminal to monitor paging messages.

[0160] 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.

[0161] 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.

[0162] In some embodiments, the first time delay is used to determine the target PEI. In other words, the target PEI may be a PEI that satisfies the first time delay in the paging cycle.

[0163] Step 2104: The network device and the terminal respectively determine the target PEI.

[0164] In some embodiments, the network device determines a PEI in the PEI set that meets a preset condition as a target PEI.

[0165] In some embodiments, the target PEI is used by the network device to instruct the terminal to detect the PDCCH on the corresponding PO and the PDSCH scheduled thereby, so as to receive the paging message sent by the network device.

[0166] The process of determining the target PEI is described in detail below by taking an example.

[0167] Example 1:

[0168] In some embodiments, the target PEI may be the first PEI after the first time delay.

[0169] In this case, the first timing can be 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; the end time point of the last wireless frame of the first LP-WUS.

[0170] 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.

[0171] In this case, the second timing can be any one of the following: the starting time point of the first symbol of the first PEI; the starting time point of the first time slot of the first PEI; the starting time point of the first subframe of the first PEI; the starting time point of the first wireless frame of the first PEI.

[0172] Example 2:

[0173] In some embodiments, for one LP-WUS among M LP-WUSs in one LP-WUS cycle, the target PEI may be one of the P PEIs after the first delay.

[0174] In this case, the first timing can be any one of the following: the first timing is the end time point of the last symbol of the channel of the second LP-WUS, 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 wireless frame of the second LP-WUS; the end time point of the LP-WUS period in which the first LP-WUS is located.

[0175] In some embodiments, the first timing may be any one of the following: the end time point of the last symbol of the channel of the third LP-WUS, where the third LP-WUS is the last LP-WUS of the c LP-WUS cycles in which the first LP-WUS is located, c is the number of LP-WUS cycles, and c≥1; the end time point of the last time slot of the third LP-WUS; the end time point of the last subframe of the third LP-WUS; the end time point of the last wireless frame of the third LP-WUS; or the end time point of c LP-WUS cycles.

[0176] In some embodiments, the P PEIs after the first time delay may be the first P PEIs after the first time delay, where is the number of POs associated with a PEI, T lpwus is the LP-WUS period, and T is the paging period.

[0177] In the above embodiment, load balancing can be achieved better than in Example 1.

[0178] In some embodiments, the P PEIs after the first time delay may be a first group of PEIs after the first time delay, and all PEIs in the PEI set are equally divided into T / (cT lpwus ) groups of PEIs, each group of PEIs including P PEIs, and determining a first group of PEIs after a first time delay.

[0179] Determining the target PEI from the P PEIs may be performed based on an index of the first LP-WUS in the LP-WUS period, P, and determining the target PEI from the P PEIs. For example, denoting the index of the first LP-WUS in the LP-WUS period as m, where m=0, 1, ..., M-1, the index of the PEI to which the first LP-WUS can be mapped in the P PEIs may be mod(m, P).

[0180] Determining the target PEI from the P PEIs may be based on the index of the first LP-WUS in the LP-WUS period, P, and the number of LP-WUSs in the LP-WUS period, and determining the target PEI from the P PEIs. For example, let the index of the first LP-WUS in the LP-WUS period be m, where m=0, 1, ...M-1. The index of the PEI to which the first LP-WUS can be mapped in the P PEIs may be or

[0181] In the above embodiment, the second timing can be any one of the following: the starting time point of the first symbol of the first PEI of P PEIs; the starting time point of the first time slot of the first PEI of P PEIs; the starting time point of the first subframe of the first PEI of P PEIs; the starting time point of the first wireless frame of the first PEI of P PEIs.

[0182] Step 2105: The network device and the terminal respectively determine the indication bit of the terminal on the target PEI.

[0183] In some embodiments, the indication bit is used to instruct the terminal to monitor paging messages on the PO associated with the target PEI.

[0184] In some embodiments, the PO associated with the target PEI is one of the PO sets configured by the system message (ie, the above-mentioned "PO configured by the system broadcast" or "paging set").

[0185] The following specifically describes the process of determining the indication bit of the terminal on the target PEI by taking an example.

[0186] Example 1:

[0187] For a terminal detecting a first LP-WUS, the paging subgroup indicator bit detected by the terminal in the PEI associated with the first LP-WUS can be calculated based on its UE ID. This method eliminates the need to restrict the position of the wakeup bit in the first LP-WUS. The paging subgroup indicator bit in the target PEI can be determined using one of the following methods:

[0188] In some embodiments, the multiple bits of the target PEI are divided into Segment, each segment bits, according to the terminal's identification, Determine the indication bit of the terminal on the target PEI.

[0189] For example, the paging subgroup indication bit of the PEI associated with the first LP-WUS of the terminal may be: in i POThe index of the PO in the PF corresponding to a PEI, i_s is the index of the PO in the PF, i_s = 0, 1, ..., N S -1,i SG is the terminal's paging subgroup index,

[0190] For example, the paging subgroup indication bit detected by the terminal in the first LP-WUS associated PEI may be:

[0191] For example, the paging subgroup indication bit detected by the terminal in the first LP-WUS associated PEI may be:

[0192] Example 2:

[0193] For a terminal detecting the first LP-WUS, the paging subgroup indication bit detected by the terminal in the PEI associated with the first LP-WUS may be calculated according to the position of the wake-up bit of the terminal in the first LP-WUS.

[0194] In some embodiments, the multiple bits of the target PEI are divided into Segment, each segment bits, and determining the indication bit of the terminal on the target PEI according to the index of the first LP-WUS in the LP-WUS cycle and the bit position in the first LP-WUS of the wake-up information indicating the terminal to wake up the MR, wherein the LP-WUS cycle in which the first LP-WUS is located includes M LP-WUSs.

[0195] For example, the index of a LP-WUS in a LP-WUS cycle is m, where m=0, 1, ...M-1, i SG is the terminal's paging subgroup index, Further introducing the parameter m′, m′ can be equal to m, or For example, This can be used in a case where M LP-WUSs in one LP-WUS cycle are associated with P adjacent PEIs.

[0196] For example, assuming that a LP-WUS only indicates the wake-up information of a system broadcast configuration PO, and LP-WUS does not indicate the information of the paging subgroup, LP-WUS can be mapped to the subgroup indication bit in PEI

[0197] For example, assuming that an LP-WUS only indicates the wake-up information of each PO of a PF configured by a system broadcast, and the LP-WUS does not indicate the information of the paging subgroup, the PO bit k of the wake-up information of the LP-WUS can be mapped to the subgroup indication bit in the PEI or, Where k = 0, 1, ..., N s -1.

[0198] For example, assuming that LP-WUS indicates the wake-up information of each PO of n PFs, and LP-WUS does not indicate the information of the paging subgroup, then the PO bit k of the wake-up information of this LP-WUS is mapped to the subgroup indication bit in PEI or, in, k=0,1,…,nN s -1.

[0199] For example, assuming that an LP-WUS only indicates the wake-up information of each paging subgroup of a system broadcast configuration PO, the PO bit k of the wake-up information of the LP-WUS can be mapped to the subgroup indication bit in the PEI in,

[0200] For example, assuming that an LP-WUS only indicates the wake-up information of the paging subgroup of each PO of the PF configured by the system broadcast, the PO bit k of the wake-up information of the LP-WUS can be mapped to the subgroup indication bit in the PEI or, in,

[0201] For example, assuming that the LP-WUS indicates the wake-up information of the paging subgroup of each PO of n PFs, the PO bit k of the wake-up information of the first LP-WUS is mapped to the subgroup indication bit or, in,

[0202] Example 3:

[0203] In some embodiments, the target PEI that meets the preset condition may be determined in a first short period.

[0204] The paging cycle includes K short cycles, each short cycle includes W PFs, W=N / K, multiple PEIs in the PEI set are divided into K groups, K groups of PEIs are associated with K short cycles in turn, the first LP-WUS is associated with the PEI, PF or PO in the first short cycle, and the first short cycle is the first short cycle after the first delay.

[0205] In this case, the second timing can be any one of the following: the starting time point of the first symbol of the PEI allocated in the first short cycle; the starting time point of the first time slot of the PEI allocated in the first short cycle; the starting time point of the first subframe of the PEI allocated in the first short cycle according to the short paging cycle; the starting time point of the first wireless frame of the PEI allocated in the first short cycle.

[0206] For example, for a terminal detecting LP-WUS, the following method can be used to determine the PF / PO mapped in the short paging cycle according to its UEID. The PF index associated with the UEID in the short paging cycle can be UE_ID mod P, and the PO index detected in this PF is still i_s=floor(UE_ID / N)mod Ns. Alternatively, the index in the PF associated with the UEID in the short paging cycle can be mod(UE_ID,P), and the PO index detected in this PF can be Alternatively, the index of the PO associated with the UEID in the short paging cycle may be UE_ID mod (P*Ns).

[0207] In the embodiment of the present disclosure, the terminal determines the target PEI in the same manner as the network device determines the target PEI, which will not be described in detail here.

[0208] Step 2106: The network device sends the target PEI to the terminal.

[0209] In some embodiments, when the target PEI indicates the paging subgroup of the terminal, the terminal detects the PDCCH on the corresponding PO and the PDSCH scheduled thereby.

[0210] In some embodiments, the terminal determines whether its corresponding bit is set by decoding the PDSCH carrying the PEI, and thus determines whether it monitors the paging message, and then monitors on the PF / PO associated with the PEI.

[0211] The paging method according to the embodiments of the present disclosure may include at least one of steps 2101 to 2106. 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 disclosure is not limited thereto. Steps 2101+2102 and steps 2101+2102+2103+2104+2105+2106 may be implemented as independent embodiments, but the present disclosure is not limited thereto.
