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

[0120] In some embodiments, for non-connected discontinuous reception (DRX) scenarios, a power saving signal (e.g., early paging indication (PEI)) is usually configured in front of a paging occasion (PO), and if the UE does not detect the power saving signal, the UE needs to skip the paging downlink control information (DCI), otherwise the UE needs to monitor the paging DCI. In order to facilitate the terminal to receive the PEI signal, an offset parameter is configured for the terminal.

[0121] 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 low power wake-up receiver (also known as a separate transceiver) 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.

[0122] In some embodiments, two paging grouping methods are defined for non-connected state:

[0123] In some embodiments, based on UE-ID grouping, the UE-ID modulo determines the random grouping method, that is, the terminal, base station, and core network three network elements reach a consensus on grouping according to the ID of the terminal.

[0124] For example, a group is obtained according to the UE-ID modulo method, and the formula is:

[0125] 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:

[0126] SubgroupID = (floor(UE_ID / (N*Ns)) mod

[0127] subgroupsNumForUEID) + (subgroupsNumperPO - SubgroupsNumForUeID),

[0128] Wherein:

[0129] N: total number of paging frames in T, T is the DRX cycle of RRC_IDLE state in the wireless resource idle state specified in clause 7.1;

[0130] Ns: number of paging times in a paging frame (PF);

[0131] UE_ID: 5G-S-TMSI mod X, where X is 32768 if eDRX is applied; otherwise, X is 8192;

[0132] subgroupsNumForUEID: number of subgroups for UE-ID based sub-grouping in PO, which is broadcast in system information;

[0133] wherein: UE-ID mod is a random selection or random allocation method (randomization). That is, UE-ID mod is performed on 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.

[0134] 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 directly allocates subgroup ID in NR. At this time, the network will allocate the subgroup ID based on the implementation, 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 random manner of UE-ID.

[0135] 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 UE-ID mod. 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.

[0136] In some embodiments, if the UE is configured with CN-based LP-WUS sub-grouping, the CN allocates the LP-WUS subgroup ID to the UE.

[0137] In some embodiments, two PEI paging packet schemes are both available in the LP-WUS. However, the specific grouping method has not been determined. For example, whether the terminal supporting the LP-WUS also supports the PEI, and how the core network decides the grouping according to the terminal capability at this time, these problems have not been discussed. The present disclosure proposes a scheme for the terminal to report auxiliary information, which is used by the core network and the base station to determine the grouping of the terminal.

[0262] FIG. 5 is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 5, the embodiment of the present disclosure relates to a communication method, for a communication system 100, the method comprising one of the following steps:

[0263] Step S5101: The terminal sends first information to the network device.

[0264] In some embodiments, the first information is used for the network device to perform grouping of paging; the first information is used to indicate the capability of the terminal supporting power saving signals, the power saving signals including at least one of the following: a first type of power saving signal; a second type of power saving signal.

[0265] 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.

[0266] In order to better understand the embodiments of the present disclosure, the following will be further described through some exemplary embodiments:

[0267] In some embodiments, a paging grouping method is protected for a low-power power saving signal (type 1 power saving signal (corresponding to the first type of power saving signal), which is distinguished from the existing type 2 power saving signal (corresponding to the second type of power saving signal)).

[0268] 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 the non-connected state.

[0269] In some embodiments, the UE reports the support capability of the type 1 power saving signal to the core network.

[0270] Scheme 1, that is, the support capabilities of the first type of power saving signal and the second type of power saving signal are regarded as independent terminal capabilities for reporting:

[0271] In some embodiments, the support capability of the terminal supporting the type 1 power saving signal does not necessarily support the type 2 power saving signal, that is, the capability of supporting the type 1 power saving signal and the capability of supporting the type 2 power saving signal are reported to the core network as different capabilities.

[0272] For example: A user supports type 1; B supports type 2; C supports the combination of type 1 and type 2.

[0273] In some embodiments, although the capability of type 1 power saving signal and the capability of supporting type 2 power saving signal are reported to the core network as different capabilities, it is agreed by the protocol that the supporting capability of type 1 power saving signal supported by the terminal must support type 2 power saving signal (still separately indicated, but the two capabilities have certain correlation); or the supporting capability of type 2 power saving signal supported by the terminal must support type 1 power saving signal.

[0274] For example, user A supports type 1 (also implicitly supports type 2); user B supports type 2, that is, the terminal supporting type 1 is a higher level terminal.

[0275] In this regard, the capabilities of the two power saving signals can be reported separately.

[0276] In some embodiments, the terminal reports different paging probability information for different types of power saving signals to assist the mobile and access management function (AMF, Access Management Function) in determining the paging grouping.

[0277] Scheme 2, that is, not considering the supporting capabilities of the first type power saving signal and the second type power saving signal as independent terminal capabilities for reporting:

[0278] In some embodiments, the supporting capability of type 1 power saving signal and the supporting capability of type 2 power saving signal are multiplexed into one capability indication:

[0279] In some embodiments, no matter whether the terminal supports type 1 power saving signal or type 2 power saving signal, or both, a single indication switch is used to indicate the support for core network paging grouping (paging subgrouping support indication, that is, the core network does not distinguish).

[0280] In some embodiments, the terminal only reports one paging probability information to assist the AMF in determining the paging grouping.

[0281] In some embodiments, the CN grouping number of the core network does not exceed 8;

[0282] In some embodiments, the core network can use part of the groupings for type 1 power saving signal grouping (corresponding to the first type grouping), and / or part of the groupings for type 2 power saving signal grouping (corresponding to the second type grouping); and / or part of the groupings for type 1 and type 2 power saving signal grouping (here, it is said that the groupings supported by the core network are distinguished themselves) (corresponding to the third type grouping).

[0283] In some embodiments, for the same user, the core network allocates two different grouping numbers for listening to type 1 and / or type 2 power saving signals.

[0284] In some embodiments, one group ID is allocated for the user supporting PEI group and the user supporting LP-WUS group respectively for power saving signal monitoring; and for the terminal supporting both types of power saving signals, two group IDs are allocated respectively for monitoring different types of power saving signals.

[0285] In some embodiments, for the terminal supporting both types of power saving signals, the core network can only allocate one type of power saving signal group number (group ID), such as not allocating LP-WUS group but allocating PEI group.

[0286] In some embodiments, the core network allocates LP-WUS and PEI group IDs for the same user by the same strategy.

[0287] In some embodiments, the core network allocates LP-WUS and PEI group IDs (possibly the same) for the user; but it is impossible that the user is only allocated LP-WUS group but not allocated PEI group.

[0288] In some embodiments, the core network allocates one unique group number for monitoring type 1 and / or type 2 power saving signals, i.e., it is impossible that the user is allocated one type 1 power saving signal group and one type 2 power saving signal group.

[0289] In some embodiments, if the terminal reports Paging Subgrouping Support Indication, the core network does not distinguish and can allocate a group ID for the terminal or does not allocate a group ID. If the core network allocates a group ID, the terminal uses the group ID to monitor LP-WUS and PEI.

[0290] In some embodiments, the same group ID is allocated for the user supporting PEI group and the user supporting LP-WUS group, i.e., the UE uses the same group ID to monitor type 1 and / or type 2 power saving signals.

[0291] In some embodiments, for the user having obtained LP-WUS group number, the group number can be continuously used for PEI monitoring without re-allocating group number, and vice versa.

[0292] The embodiments of the present disclosure further propose an apparatus for implementing any of the above methods, for example, an apparatus including units or modules for implementing each step performed by the terminal in any of the above methods.
