Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0166] In some embodiments, for non-connected discontinuous reception (DRX) scenarios, a power saving signal (PEI, paging early indication) is usually configured in front of a paging occasion (PO, paging occasion), and if the UE does not detect the power saving signal, it needs to skip the paging downlink control information (DCI, download control information), otherwise it needs to monitor the paging DCI. In order to facilitate the terminal to receive the PEI signal, an offset parameter will be configured to the terminal.

[0167] In some embodiments, regardless of the power saving signal, the modem of the terminal needs to detect the power saving signal at this time. However, it is desirable to introduce a separate transceiver (low power wake-up receiver) to receive the power saving signal, and the modem part or main radio part of the terminal can only be awakened after the separate transceiver is awakened, otherwise the modem part will always be in a dormant state.

[0168] In some embodiments, two paging grouping methods are defined for non-connected state:

[0169] In some embodiments, based on UE-ID grouping, UE-ID modulo determines the random way of grouping, that is, the terminal, base station, and core network three network elements reach agreement on grouping consistency according to the ID of the terminal.

[0170] Exemplarily, a group is obtained according to the UE-ID modulo method, and the formula is:

[0171] If the UE is not configured with a CN-assigned subgroup ID, or if the UE configured with a CN-assigned subgroup ID is in a cell that only supports UE-ID-based subgroup, the subgroup ID of the UE is determined by the following formula:

[0172] SubgroupID = (floor(UE_ID / (N*Ns)) mod subgroupsNumForUEID) + (subgroupsNumperPO-SubgroupsNumForUeID),

[0173] Wherein:

[0174] N: total number of paging frames in T, T is the DRX cycle of the RRC_IDLE state of the wireless resource idle state specified in clause 7.1;

[0175] Ns: the number of paging times in a paging frame (PF);

[0176] UE_ID: 5G-S-TMSI mod X, where X is 32768 if eDRX is applied; otherwise, X is 8192;

[0177] subgroupsNumForUEID: the number of subgroups for UE-ID based sub-grouping in a PO, which is broadcast in system information;

[0178] Wherein: the UE-ID mod way is a random selection or random allocation way (randomization). That is, the UE-ID mod is performed in all paging group resources. It can be seen that N is the paging frame density in the time domain, and Ns is the paging density in a paging frame in the time domain.

[0179] In some embodiments, the network configures the terminal paging grouping manner based on the CN grouping, and agrees to be performed by the core network as a unified node. It can be seen that at this time, it is different from the allocation probability manner in LTE, but a subgroup ID is directly allocated in NR. At this time, the network will be based on the implementation of allocation when allocating the subgroup ID, such as according to the terminal attribute, or the statistical paging probability, etc. Therefore, we can consider that there are two paging grouping manners, one is based on network allocation, and the other is the UE-ID random manner.

[0180] In some embodiments, the terminal decides its belonging group according to its own support capability and the support capability of the network; the group can be a network allocated group ID, or a group ID obtained by the UE-ID mod way. The terminal will listen to the bit position carried in the corresponding PEI based on this; the PEI is a DCI carrier, which carries the wake-up indication bit of the corresponding group. If it is "1", it is wake-up, otherwise it is sleep.

[0181] In some embodiments, both PEI paging grouping schemes are available in the LP-WUS. At this time, the base station will configure the respective grouping numbers for the core network (CN-Based) grouping scheme and the terminal identifier (UE-ID based) grouping scheme.

[0182] In some embodiments, after the LP-WUS enters, the CN-Based grouping scheme and the UE-ID based grouping scheme are also agreed. At this time, the base station needs to configure the grouping resources for LP-WUS monitoring. However, whether there is a mapping relationship between the grouping resources for LP-WUS monitoring and the grouping resources for the existing PEI, and how to reduce false alarms, are problems that need to be considered.

[0183] FIG. 2a is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 2a, the embodiment of the present disclosure relates to a communication method for a communication system 100, and the method comprises:

[0184] Step S2101: The terminal sends first information to the network device.

[0185] In some embodiments, the network device receives the first information sent by the terminal.

[0186] In some embodiments, the first information is used to indicate that the terminal supports determining the first type of paging group based on the first mode and / or the second mode.

[0187] In some embodiments, the first information is used to indicate that the terminal does not support determining the first type of paging group based on the first mode and / or the second mode.

[0188] In some embodiments, the first information is used to indicate that the terminal supports the first type of power saving signal and supports determining the first type of paging group based on the second mode.

[0189] In some embodiments, if the terminal supports the first type of power saving signal, the terminal supports determining the first type of paging group based on the second mode.

[0190] In some embodiments, the first mode is a core network CN-based grouping mode.

[0191] In some embodiments, the second mode is a terminal identifier UE-ID-based grouping mode.

[0192] In some embodiments, the first type of paging group is a group for monitoring the first type of power saving signal.

[0193] In some embodiments, the first type of power saving signal is a low-power wake-up signal LP-WUS.

[0194] In some embodiments, the terminal supports monitoring of the first type of power saving signal, and the terminal supports paging grouping based on the first type of power saving signal.

[0195] In some embodiments, the network device can specify an x number of groups in the packet for grouping based on the first manner; and / or the network device can specify a y number of groups in the packet for grouping based on the second manner.

[0196] Step S2102: The network device sends second information to the terminal.

[0197] In some embodiments, the terminal receives the second information sent by the network device.

[0198] In some embodiments, the second information is used to indicate that the first type of power saving signal is used by the terminal in a released connection.

[0199] Step S2103: The network device determines a paging group.

[0200] In some embodiments, the first type of paging group is determined based on the first manner, and the first manner is a core network (CN) based grouping manner.

[0201] In some embodiments, the first type of paging group is determined based on the second manner, and the second manner is a terminal identifier (UE-ID) based grouping manner.

[0202] In some embodiments, if the terminal is allocated the first type of paging group based on the first manner, the terminal performs listening of the first type of power saving signal based on the first type of paging group based on the first manner.

[0203] In some embodiments, if the terminal is not allocated the first type of paging group based on the first manner and supports performing paging grouping based on the second manner, the terminal performs listening of the first type of power saving signal based on the first type of paging group based on the second manner.

[0204] In some embodiments, if the terminal cannot obtain the group identifier, the terminal does not use the first type of paging group.

[0205] Step S2104: The network device determines a resource.

[0206] In some embodiments, the network device determines the first resource.

[0207] In some embodiments, the first resource is a resource associated with the first type of paging group determined based on the first manner.

[0208] In some embodiments, the network device determines the second resource.

[0209] In some embodiments, the second resource is a resource associated with the first type of paging group determined based on the second manner.

[0210] It should be noted that the determined resource can be used for resource allocation in step S2106.

[0211] Exemplarily, the allocated resource can be the determined resource or part of the determined resource.

[0212] Step S2105: The network device determines the number of paging packets.

[0213] In some embodiments, if the first type of power saving signal is configured, the number of the first type of paging packets is the same as the number of the second type of packets.

[0214] In some embodiments, the number of the first type of paging packets determined based on the first manner is the same as the number of the second paging packets determined based on the first manner.

[0215] In some embodiments, the number of the first type of paging packets determined based on the second manner is the same as the number of the second paging packets determined based on the second manner.

[0216] In some embodiments, the sum of the number of the first type of paging packets determined based on the first manner and the number of the first type of paging packets determined based on the second manner is the same as the sum of the number of the second type of paging packets determined based on the first manner and the number of the second paging packets determined based on the second manner.

[0217] In some embodiments, the second type of paging packet is a packet for monitoring a second type of power saving signal.

[0218] In some embodiments, the second type of power saving signal is a paging early indication (PEI).

[0219] In some embodiments, if the first type of power saving signal is configured, the packet number of the first type of paging packet determined based on the second manner is determined based on a network configuration value or a protocol agreement value and a first number; the first number is the number of paging packets determined based on the second manner for the first type of power saving signal configured by the network; and the second manner is a grouping manner based on a terminal identifier (UE-ID).

[0220] Exemplarily, if the base station configures an LP-WUS, the packet number of the LP-WUS UE ID is calculated as follows:

[0221] SubgroupID = (floor(UE_ID / (N*Ns*total Number for UE-ID based PEI M)) mod subgroupsNumForUEID) + (subgroupsNumperPO-SubgroupsNumforUEID), or SubgroupID = ((floor(UE_ID / (N*Ns)) mod subgroupsNumForUEID) mod M) + (subgroupsNumperPO-SubgroupsNumforUEID),

[0222] wherein subgroupsNumForUEID is the number of groups of UE iD for LP-WUS configured by the network;

[0223] subgroupsNumPerPO is the total number of groups for LP-WUS configured by the network;

[0224] N: total number of paging frames in T, T is the Discontinuous Reception (DRX) cycle in RRC_IDLE state specified in clause 7.1

[0225] Ns: number of paging times of PF;

[0226] M: i.e. the value agreed upon by the protocol or configured by the network;

[0227] In some embodiments, M can be total Number for UE-ID based PEI, i.e. the number of groups of UE iD for PEI configured by the network;

[0228] In some embodiments, if for users supporting PEI, total Number for UE-ID based PEI is the number of groups of UE iD for PEI configured by the network;

[0229] In some embodiments, if for users not supporting PEI, M = 1;

[0230] In this way, for terminals supporting both LP-WUS and PEI, the SubgroupID calculated using the formula is different for the two types of signals. This can reduce the false wake-up rate of paging.

[0231] In some embodiments, if the second type of power saving signal is configured, the packet number of the second type of paging packet determined based on the second manner is determined based on a network configured value or a protocol agreed value, and a second number; the second number is a network configured number of paging packets determined based on the second manner for the second type of power saving signal; and the second manner is a grouping manner based on a terminal identifier (UE-ID).

[0232] For example, if the base station configures PEI, for a user who supports both PEI and LP-WUS, the grouping number of the PEI UE-ID is calculated as follows:

[0233] SubgroupID = (floor(UE_ID / (N*Ns*M’)) mod subgroupsNumForUEID) + (subgroupsNumperPO-SubgroupsNumforUEID), or SubgroupID = ((floor(UE_ID / (N*Ns*M’)) mod subgroupsNumForUEID) mod M’) + (subgroupsNumperPO-SubgroupsNumforUEID),

[0234] wherein subgroupsNumForUEID is a network configured number of grouping numbers of UE-ID for PEI;

[0235] subgroupsNumPerPO is a network configured total number of grouping numbers for PEI;

[0236] N: total number of paging frames in T, T is a DRX cycle in RRC_IDLE state specified in clause 7.1

[0237] Ns: number of paging times of PF;

[0238] M’: a protocol agreed value or a network configured value;

[0239] In some embodiments, M’ can be total Number for UE-ID based LP-WUS, i.e., a network configured number of grouping numbers of UE-ID for LP-WUS;

[0240] In some embodiments, for a user who supports both PEI and LP-WUS, M’ can be total Number for UE-ID based LP-WUS, i.e., a network configured number of grouping numbers of UE-ID for LP-WUS;

[0241] In some embodiments, for a user who does not support PEI, M’ = 1;

[0242] Thus, for the terminal supporting both the LP-WUS and the PEI, the SubgroupID calculated by the formula is different for the two types of signals. Thus, the false wake-up rate of paging can be reduced.

[0243] In some embodiments, for the terminal supporting both the first type of power saving signal and the second type of power saving signal, different subgroup numbers (SubgroupID) are used.

[0244] Step S2106: The network device performs an operation.

[0245] In some embodiments, the operation can be an operation of allocating resources and / or an operation of establishing a mapping relationship.

[0246] In some embodiments, the network device allocates resources for the terminal to perform listening based on the first type of paging group and / or the second type of paging group.

[0247] In some embodiments, there is a mapping relationship between the resources associated with the first type of paging group and the resources associated with the second type of paging group.

[0248] In some embodiments, the network device establishes a mapping relationship between the first type of paging group and the second type of paging group.

[0249] In some embodiments, the network device establishes a mapping relationship between the resources associated with the first type of paging group and the resources associated with the second type of paging group.

[0250] In some embodiments, based on the protocol rule information, the network device establishes a mapping relationship between the first type of paging group and the second type of paging group.

[0251] In some embodiments, the terminal determines that there is no mapping relationship between the first type of paging group and the second type of paging group, and performs paging listening after being woken up by the first type of power saving signal.

[0252] In some embodiments, the terminal determines that there is no mapping relationship between the first type of paging group and the second type of paging group, and the terminal supporting the second type of paging group does not use the first type of power saving signal to perform listening.

[0253] In some embodiments, the network device sends third information to the terminal, and the third information is used to indicate the mapping relationship.

[0254] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0255] In some embodiments, the term "sending" can be mutually replaced with the terms "transmitting", "reporting", "transferring", and the like.

[0332] Step S5101: The terminal sends first information to the network device.

[0333] In some embodiments, the first information is used to indicate one of the following: the terminal supports determining the first type of paging group based on a first manner and / or a second manner; the terminal does not support determining the first type of paging group based on the first manner and / or the second manner; the first manner is a core network (CN) based grouping manner, and the second manner is a terminal identifier (UE-ID) based grouping manner; there is a mapping relationship between the first type of paging group and a second type of paging group; the first type of paging group is a group for a first type of power saving signal monitoring, and the second type of paging group is a group for a second type of power saving signal monitoring.

[0334] In some embodiments, the above method can include the methods of the above network device side and terminal side embodiments, which are not described here.

[0335] In order to better understand the embodiments of the present disclosure, the following is further illustrated through some exemplary embodiments:

[0336] In some embodiments, a paging group manner for protecting a low-power power saving signal (type 1 power saving signal (i.e., first type of power saving signal), distinguished from an existing type 2 power saving signal (i.e., second type of power saving signal)) is provided.

[0337] In some embodiments, the type 1 power saving signal is an LP-WUS, and the type 2 power saving signal includes a PEI (paging early indication) used by the terminal in an unconnected state.

[0338] In some embodiments, the UE reports a support capability of listening to the type 1 power saving signal in the UE-ID based grouping manner to the base station.

[0339] In some embodiments, the UE reports a support capability of supporting the type 1 power saving signal and supporting the UE-ID based grouping manner to the base station.

[0340] In some embodiments, the support capability of the terminal supporting the type 1 power saving signal necessarily supports a mechanism of grouping paging according to the LP-WUS.

[0341] In some embodiments, the support capability of the terminal supporting the type 1 power saving signal necessarily supports a mechanism of UE-ID based grouping paging.

[0342] In some embodiments, for a terminal, if the terminal is assigned a core network grouping based on LP-WUS, the terminal performs LP-WUS monitoring according to the grouping ID assigned by the core network (corresponding to the first mode); otherwise, if there is no core network grouping based on LP-WUS, the terminal needs to make a further decision. At this time, if UE id based grouping is supported (corresponding to the second mode), and the base station also supports UE id based grouping, the terminal performs LP-WUS grouping according to the UE id modulo.

[0343] In some embodiments, if the terminal cannot find a sub-group ID in the LP-WUS configuration of the cell, the terminal does not use LP-WUS grouping.

[0344] In some embodiments, the base station configures the time-frequency domain resources corresponding to the LP-WUS grouping.

[0345] In some embodiments, the base station can specify some of the LP-WUS groupings for the UE-ID based LP-WUS grouping mode; the rest are used for the CN-ID based LP-WUS grouping mode.

[0346] In some embodiments, the base station can specify some of the LP-WUS groupings for the CN-ID based LP-WUS grouping mode; the rest are used for the UE-ID based LP-WUS grouping.

[0347] In some embodiments, the base station or the protocol establishes a mapping relationship between the LP-WUS grouping and the PEI grouping.

[0348] In some embodiments, the base station or the protocol establishes a one-to-one mapping relationship between the LP-WUS grouping and the PEI grouping.

[0349] In some embodiments, there can be a LP-WUS grouping without a PEI grouping and a mapping relationship between them.

[0350] At this time, after being woken up by the LP-WUS, the terminal will directly monitor the PO;

[0351] In some embodiments, there can be a PEI grouping without a LP-WUS grouping and a mapping relationship between them.

[0352] At this time, the user of the PEI grouping will not use LP-WUS.

[0353] In some embodiments, if the base station configures LP-WUS, the total number of groupings and the number of groupings in the PEI grouping are the same (Embodiment 1, please refer to FIG. 6a).

[0354] In some embodiments, the number of groups of CN-based grouping manner and the number of groups of UE ID in the PEI group are consistent if the base station configures LP-WUS.

[0355] In some embodiments, the number of groups of CN-based grouping manner and the number of groups of UE ID in the PEI group are consistent if the base station configures LP-WUS.

[0356] In some embodiments, the sum of the number of groups of LP-WUS CN-based grouping manner and the number of groups of UE ID is consistent with the sum of the number of groups of PEI CN-based grouping manner and the number of groups of UE ID if the base station configures LP-WUS.

[0357] In some embodiments, for users supporting both LP-WUS and PEI, the SubgroupID used is different for the two types of signals.

[0358] In some embodiments, the number of groups of LP-WUS UE ID is calculated as follows if the base station configures LP-WUS:

[0359] SubgroupID = (floor(UE_ID / (N*Ns*M)) mod subgroupsNumForUEID) + (subgroupsNumperPO-SubgroupsNumforUEID), or SubgroupID = ((floor(UE_ID / (N*Ns)) mod subgroupsNumForUEID) mod M) + (subgroupsNumperPO-SubgroupsNumforUEID),

[0360] wherein subgroupsNumForUEID is the number of groups of UE ID for LP-WUS configured by the network;

[0361] subgroupsNumPerPO is the total number of groups for LP-WUS configured by the network;

[0362] N: total number of paging frames in T, T is the DRX cycle of RRC_IDLE state specified in clause 7.1;

[0363] Ns: number of paging times of PF;

[0364] M: i.e. the protocol agreed value or the value configured by the network;

[0365] In some embodiments, M can be the total number of UE-ID based PEI groups configured by the network for PEI;

[0366] In some embodiments, if for the user supporting PEI, the total number of UE-ID based PEI is the number of UE-ID groups configured by the network for PEI;

[0367] In some embodiments, if for the user not supporting PEI, M = 1;

[0368] At this point, for the user supporting both LP-WUS and PEI, the SubgroupID calculated by the formula is not the same for the two types of signals. Then the false wake-up rate of paging can be reduced.

[0369] In some embodiments, if the base station configures PEI, for the user supporting both PEI and LP-WUS, the number of PEI UE-ID groups is calculated as follows:

[0370] SubgroupID = (floor(UE_ID / (N*Ns*M’)) mod subgroupsNumForUEID) + (subgroupsNumperPO-SubgroupsNumforUEID), or SubgroupID = ((floor(UE_ID / (N*Ns*M’)) mod subgroupsNumForUEID) mod M’) + (subgroupsNumperPO-SubgroupsNumforUEID),

[0371] Wherein, subgroupsNumForUEID is the number of UE-ID groups configured by the network for PEI;

[0372] subgroupsNumPerPO is the total number of groups configured by the network for PEI;

[0373] N: total number of paging frames in T, T is the DRX cycle of RRC_IDLE state specified in clause 7.1;

[0374] Ns: the number of paging times of PF;

[0375] M’: the value agreed upon by the protocol or configured by the network;

[0376] In some embodiments, M' can be the total number for UE-ID based LP-WUS, i.e., the number of groups of UE IDs configured by the network for LP-WUS;

[0377] In some embodiments, for users supporting both PEI and LP-WUS, M' can be the total number for UE-ID based LP-WUS, i.e., the number of groups of UE IDs configured by the network for LP-WUS;

[0378] In some embodiments, for users not supporting PEI of LP-WUS, M' = 1.

[0379] In this way, for terminals supporting both LP-WUS and PEI, the SubgroupID calculated by the formula is different for the two types of signals, and the false wake-up rate of paging can be reduced.

[0380] In some embodiments, the base station can indicate whether the LP-WUS signal of the cell is only for users released locally (corresponding to the third information), at this time, the indication bit can be multiplexed with the lastUsedCellOnly indication bit of PEI, or can be a different lastUsedCellOnly indication bit.
