The above DRX mechanism is applicable to terminal devices in the Radio Resource Control (RRC) connected state (Connected). For terminal devices in the RRC non-connected state, such as the RRC idle (Idle) state or the inactive (inactive) state, the main power consumption lies in the periodic reception of paging messages.

[0044] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located in the coverage area.

Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0046] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0047] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0048] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0049] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0050] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0051] In order to save power for the terminal equipment, the DRX transmission mechanism is introduced to achieve discontinuous reception of signals in the time domain through semi-static configuration. When there is no data transmission, the power consumption can be reduced by stopping receiving PDCCH (PDCCH blind detection will be stopped at this time).

[0052] Specifically, a DRX cycle is configured for a terminal device in a Radio Resource Control (RRC) connected state (RRC_CONNECTED). Figure 2 As shown in the figure, the DRX cycle is divided into continuous DRX cycles in the time domain. The DRX cycle consists of an active period (Active Time, or On Duration) and an inactive period or a dormant period (Opportunity for DRX). During the active period, the terminal device monitors and receives downlink channels and downlink signals including PDCCH; during the inactive period or the dormant period, the terminal device does not receive downlink channels and downlink signals such as PDCCH to reduce power consumption. It should be noted that Opportunity for DRX is the inactive period or the dormant period of DRX.

[0053] Terminal devices in the RRC idle state can receive paging messages in a similar way to DRX. There is a paging occasion (PO) in a DRX cycle. Terminal devices only receive paging messages during PO, and do not receive paging messages outside of PO to save power. During PO, the UE determines whether there is a paging message by detecting the PDCCH scrambled by the Paging Radio Network Temporary Identity (P-RNTI).

[0054] Although the network equipment configures the DRX mechanism for the terminal device, the terminal device is only opportunistically scheduled during the periodic on duration. Even when the terminal device's service load is very low, the terminal device will only be scheduled in a few DRX cycles. For paging messages using the DRX mechanism, the terminal device receives paging messages even less frequently. Therefore, after the terminal device configures the DRX mechanism, there are still cases where the PDCCH detection in most on durations does not detect data scheduling. If the terminal device blindly detects the PDCCH when there is no data scheduling, the detection power is wasted. Therefore, there is room for further optimization of the current DRX mechanism.

[0055] The DRX enhancement mechanism is introduced in 5G and LTE evolution projects. When the network equipment determines that the terminal device needs to be scheduled during the DRX ONduration, it sends an energy-saving signal to the terminal device, which is used to wake up the terminal device. When the terminal device has data transmission in a DRX cycle, the energy-saving signal "wakes up" the terminal device to monitor the PDCCH during the DRX Onduration; otherwise, when the terminal device has no data transmission in a DRX cycle, the energy-saving signal does not "wake up" the terminal, and the terminal device does not need to monitor the PDCCH during the DRX On Duration. Compared with the previous DRX mechanism, when the terminal device has no data transmission, the terminal device can omit the PDCCH monitoring during the DRX On duration, thereby achieving energy saving. Figure 3 This is a schematic diagram of instructing the terminal whether to monitor the PDCCH during the DRX On duration through the energy-saving signal.

[0056] The main function of paging is to enable the network equipment to page the UE through a paging message when the UE is in the Radio Resource Control (RRC) idle state or the RRC inactive state, or to notify the UE of system message changes or earthquake tsunami / public warning information through a short message (applicable to all RRC states of the UE, including the connected state).

[0057] For UE in RRC_IDLE state or RRC_INACTIVE state, since there is no other data communication between UE and the network, in order to save power of the terminal, UE can monitor paging messages discontinuously, that is, adopt paging discontinuous reception (DRX) mechanism. Under the Paging DRX mechanism, UE only needs to monitor paging during one paging occasion (PO) in each DRX cycle.

[0058] Optionally, PO is composed of a series of PDCCH monitoring opportunities, where each PDCCH monitoring opportunity may include one or more time slots. Specifically, in a DRX cycle, the terminal device may monitor PDCCH on a PO on a paging radio frame (PF). PF may refer to a radio frame, for example, a fixed 10ms, which may contain one or more POs, or the starting position of one or more POs.

[0059] Optionally, the period of Paging DRX is jointly determined by a common period in system broadcast and a dedicated period configured in a higher layer signaling (eg, Non-Access Stratum (NAS) signaling). For example, the UE may take the minimum period of the two as the Paging Cycle.

[0060] From the network's perspective, a paging DRX cycle can have multiple POs. The PO position of the UE monitoring PDCCH is related to the UE_ID. The UE only needs to monitor its own PO. The PF and PO of a UE monitoring PDCCH in a Paging DRX can be determined as follows.

[0061] For example, the PF system frame number (SFN) is determined by the following formula:

[0062] (SFN+PF_offset)mod T=(T / N)*(UE_ID mod N)

[0063] The index (i_s) of a PO in a PF is determined by the following formula:

[0064] i_s=floor(UE_ID / N)mod Ns

[0065] Wherein, mod represents modulus, and T represents the DRX cycle of the UE receiving paging. In some implementations, the network may broadcast a default DRX cycle. If the upper layer of the network device, for example, the RRC layer, configures a UE-specific DRX cycle for the UE, the UE may use the minimum of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the upper layer as the DRX cycle of the UE. If the upper layer of the network device does not configure a UE-specific DRX cycle for the UE, the UE may use the DRX cycle broadcast by the network as the DRX cycle of the UE.

[0066] N represents the number of PFs included in a DRX cycle;

[0067] Ns represents the number of POs contained in a PF;

[0068] PF_offset represents a time domain offset used to determine PF;

[0069] UE_ID, for example, can be 5G-S-TMSI mod 1024, where 5G-S-TMSI is the 5G shortened temporary mobile user identity (Temporary Mobile Subscriber Identity, TMSI).

[0070] For a terminal device in an RRC non-connected state, the main power consumption is due to periodic reception of paging messages. Therefore, how to achieve energy saving of the terminal device in the RRC non-connected state is an urgent problem to be solved.

[0071] Figure 4 Schematic interactive diagram of an energy saving method 200 provided in an embodiment of the present application. Figure 4 As shown, the method 200 may include at least part of the following:

[0072] S210, the network device sends first information, wherein the first information includes paging energy-saving configuration information corresponding to each terminal device group in a plurality of terminal device groups, wherein each terminal device group includes at least one terminal device, and the paging energy-saving configuration information corresponding to the terminal device group is used to determine whether at least one terminal device in the terminal device group receives a paging message;

[0073] Correspondingly, the terminal device receives the first information;

[0074] S220, the terminal device receives a paging message according to the paging energy-saving configuration information corresponding to the terminal device group to which the terminal device belongs.

[0075] It should be understood that the terminal device can be Figure 1 The terminal device 120 in the embodiment shown may be a network device Figure 1 The network device 110 in the illustrated embodiment.

[0076] In an embodiment of the present application, the terminal device is in an RRC non-connected state, such as an RRC Idle state or an RRC inactive state.

[0077] Optionally, in some embodiments, the multiple terminal device groups belong to one paging group, that is, one paging group may include multiple terminal device groups, or one terminal device group may be considered as a paging subgroup, that is, one paging group may include multiple paging subgroups.

[0078] Therefore, in the embodiment of the present application, a paging group can be divided into multiple terminal device groups, and by configuring corresponding paging energy-saving configuration information for each terminal device group, the reception control of paging messages is performed in units of terminal device groups, which can achieve a better energy-saving effect than the reception control of paging messages in units of paging groups. This is because when the reception of paging messages is controlled in units of paging groups, if only some of the terminal devices in a paging group need to receive paging messages, the network device must instruct all terminal devices in the paging group to receive paging messages, which will cause power consumption of terminal devices that do not need to receive paging messages.

[0079] In some embodiments, it can be considered that terminal devices corresponding to the same PF or PO belong to one paging group. The calculation method of PF and PO refers to the above description.

[0080] In some embodiments, the terminal device may determine the terminal device group to which it belongs. For example, the terminal device group to which the terminal device belongs may be determined according to a preset rule. Correspondingly, the network device may also determine the terminal device group to which each terminal device belongs according to the preset rule, and further configure corresponding paging energy saving configuration information for each terminal device group.

[0081] As an example, the preset rule may be to determine the terminal device group to which the terminal device belongs according to an identification (Identify, ID) of the terminal device.

[0082] Optionally, the ID of the terminal device may be, for example, 5G-S-TMSI mod 1024, or may be other identification information that can identify the terminal device, but the present application is not limited thereto.

[0083] In some embodiments, the terminal device group to which the terminal device belongs may be determined according to the following formula:

[0084] Index_UEGroup=UE_ID mod N_UEGroup

[0085] Among them, Index_UEGroup is the index of the terminal device group, and N_UEGroup is the total number of the multiple terminal device groups.

[0086] Optionally, in some embodiments, the first information may be carried in downlink control information (Downlink Control Information, DCI), or may be carried in other downlink signals, downlink channels or downlink messages, for example, carried in a downlink reference signal sequence. Below, the first information is carried in DCI as an example for explanation, but the present application is not limited to this.

[0087] Optionally, the DCI may be DCI format 2_6 or DCI format 1_0, or may be other DCI formats, but the present application is not limited thereto.

[0088] Optionally, in some embodiments, the DCI may include multiple information blocks, each information block being used to carry paging energy-saving configuration information corresponding to a terminal device group.

[0089] In an embodiment of the present application, after receiving the first information, the terminal device can determine the position of the paging energy-saving configuration information corresponding to the terminal device group to which the terminal device belongs in the first information.

[0090] In some embodiments, the paging energy-saving configuration information corresponding to the multiple terminal device groups is arranged according to a preset rule. The preset rule may be a rule that both the terminal device and the network device can know. When the network device generates the first information, the paging energy-saving configuration information corresponding to each terminal device group is arranged according to the preset rule. The terminal device may also determine the position of the paging energy-saving configuration information corresponding to the terminal device group to which it belongs according to the preset rule, and further obtain the paging energy-saving configuration information.

[0091] In some embodiments, the first information is carried in a DCI, and the information block in the DCI and the terminal device group may have a corresponding relationship. The terminal device may determine the position of the paging energy saving configuration corresponding to the terminal device group to which it belongs in the DCI according to the terminal device group to which it belongs and the corresponding relationship.

[0092] As an embodiment, the terminal device may determine the position of the paging energy-saving configuration information corresponding to the terminal device group to which the terminal device belongs in the first information according to the ID of the terminal device.

[0093] As an example, the terminal device can determine the position of the paging energy-saving configuration information corresponding to the terminal device group to which the terminal device belongs in the first information based on the ID of the terminal device and the total number of the multiple terminal device groups (or the total number of paging energy-saving configuration information corresponding to the multiple terminal device groups, or the number of multiple signal blocks).

[0094] Assuming there are N terminal equipment groups, there are N paging energy saving configuration information, the N terminal equipment groups correspond to the N paging energy saving configuration information one by one, and each paging energy saving configuration information corresponds to a corresponding index, recorded as Index_UEGroup_Config. As an example, Index_UEGroup_Config=UE_ID mod N.

[0095] In other embodiments, the first information is carried in a reference signal sequence. In this case, different terminal device groups can be indicated by different reference signal sequences, or by time-frequency resources for transmitting the reference signal sequences. In other words, paging energy-saving configuration information of different terminal device groups can be carried by different reference signal sequences, or reference signal sequences carrying paging energy-saving configuration information corresponding to different terminal device groups can be transmitted by different time-frequency resources.

[0096] It should be understood that the embodiments of the present application do not limit the specific implementation method of the paging energy-saving configuration information corresponding to each terminal device. As examples, several typical implementation methods are described in combination with Embodiments 1 to 4.

[0097] Example 1

[0098] The paging energy saving configuration information corresponding to the terminal device group includes a paging energy saving indication information, and the paging energy saving indication information is used to indicate whether at least one terminal device in the terminal device group receives a paging message.

[0099] That is, each terminal device group may correspond to a paging energy-saving indication information, and the paging energy-saving indication information is used to indicate whether at least one terminal device in the terminal device group receives a paging message.

[0100] It should be understood that in this embodiment 1, whether at least one terminal device in the terminal device group receives a paging message may refer to whether the terminal device group receives a paging message within a specific time period. The specific time period may refer to the PF or PO corresponding to the terminal device group, wherein the calculation method of the PF or PO corresponding to the terminal device group refers to the above description.

[0101] In some embodiments, the paging energy saving indication information corresponding to each terminal device group may be 1 bit. Different values ​​of the 1 bit are used to indicate whether at least one terminal device in the terminal device group receives a paging message. For example, the 1 bit value of 1 indicates receiving a paging message, and the value of 0 indicates not receiving a paging message, or vice versa.

[0102] In some embodiments, the first information is carried in a DCI format (format) 2_6, and the DCI format format 2_6 includes multiple information blocks, each of which includes a wake-up indication bit and a secondary cell sleep indication bit. As an example, the paging energy-saving configuration information corresponding to each terminal device group is carried in an information block in DCI format 2_6, and more specifically, the paging energy-saving indication information corresponding to the terminal device group can be carried in the wake-up indication bit of the information block in the DCI format 2_6.

[0103] Figure 5 This is an example of the format of the first information based on embodiment 1. The first information can carry paging energy-saving indication information of N terminal device groups. The paging energy-saving indication information of each terminal device group is used to indicate whether the corresponding terminal device group receives a paging message, such as Figure 6 shown.

[0104] Example 2

[0105] The paging energy saving configuration information corresponding to the terminal device group includes a paging energy saving indication information and time information corresponding to the paging energy saving indication information.

[0106] The paging energy-saving indication information is used to indicate whether at least one terminal device in the terminal device group receives a paging message, and the time information corresponding to the paging energy-saving indication information indicates the valid time period corresponding to the content indicated by the paging energy-saving indication information. It should be understood that the valid time period here can be continuous, for example, a continuous period of time, or can also be discrete, such as a discrete PO or PF, and this application does not limit this.

[0107] Then, the terminal devices in each terminal device group may determine whether to receive a paging message within the valid time period according to the corresponding paging energy-saving indication information and the valid time period corresponding to the content indicated by the paging energy-saving indication information.

[0108] By configuring the effective time period of the content indicated by the paging energy-saving indication information, it is possible to more flexibly indicate the time period for the terminal device to receive the paging message, thereby saving signaling overhead and further improving the energy-saving effect.

[0119] Optionally, the time period corresponding to each bit may be continuous, for example, a continuous period of time. In this case, each bit may be considered to correspond to a PF or PO in the period of time; or, the time period corresponding to each bit may be discrete, for example, multiple discrete POs.

[0127] The terminal devices in each terminal device group can determine whether to receive a paging message within the valid time period according to the valid time periods respectively corresponding to the multiple paging energy-saving indication information and the contents indicated by the multiple paging energy-saving indication information.

[0128] By configuring multiple paging energy-saving indication information for each terminal device group, and the valid time periods corresponding to the contents indicated by the multiple paging energy-saving indication information, it is possible to more flexibly indicate the time periods for the terminal devices to receive paging messages, saving signaling overhead and further improving energy-saving effects.

[0134] The terminal devices in each terminal device group can determine whether to receive a paging message within the valid time period according to multiple paging energy-saving indication information and the time periods respectively corresponding to the multiple paging energy-saving indication information.

[0135] By configuring multiple paging energy-saving indication information for each terminal device group, it is possible to more flexibly indicate the time period for the terminal device to receive paging messages, save signaling overhead, and further improve the energy-saving effect.

[0136] Optionally, the time period corresponding to each paging energy-saving indication information in the multiple paging energy-saving indication information may be predefined, or may be configured by the network device, for example, through paging configuration information.

[0137] Optionally, the implementation method of the time information corresponding to the paging energy-saving indication information may refer to the relevant description in Example 2, which will not be repeated here for the sake of brevity.

[0139] It should be understood that Figures 5 to 10 This is only an example. The paging energy-saving configuration information may also have other possible implementations. Other implementations derived from the teachings of the embodiments of the present application all fall within the protection scope of the embodiments of the present application.

[0140] Optionally, in some embodiments, the information field in the existing DCI format may be reused to carry the first information.

[0141] For example, for DCI format 2_6, the paging energy saving configuration information corresponding to each terminal device group can be carried in the information block in the DCI format 2_6.

[0142] Optionally, if the size of an information block in DCI format 2_6 is not sufficient to carry the paging energy-saving configuration information corresponding to a terminal device group, for example, the size of an information block is 6 bits, and the paging energy-saving configuration information corresponding to the terminal device group requires 8 bits, in this case, the size of the information block in the DCI format 2_6 can be re-divided so that each information block is sufficient to carry the paging energy-saving configuration information corresponding to a terminal device group.

[0143] Optionally, in some embodiments, the information field in DCI format1_0 may be multiplexed to carry the first information.

[0144] In the related art, DCI format 1_0 can carry short message indicator information (2 bits), short message information (8 bits), and scheduling information of a PDSCH carrying a paging message.

[0145] Among them, the short message indication information represents the content carried by the DCI, as shown in the following table.

[0146] Bit field value Short Message indicator 00 Reserve 01 In DCI, there is only scheduling information for paging. 10 There is only a short message in DCI 11 DCI has scheduling information and short messages for paging.

[0147] As an example, by setting the Short Message indicator value in the DCI format 1_0 to 00, it is indicated that the DCI is used to indicate information related to paging energy saving, and the first information is further carried through other information fields in the DCI format 1_0. For example, the first information is carried through the short message information field in the DCI format 1_0 and / or the scheduling information field of the PDSCH.

[0149] In some embodiments, for DCI format 1_0, the information field in DCI format 1_0 used to carry the first information can also be divided into multiple information blocks, which are used to carry the paging energy-saving configuration information corresponding to each terminal device group. The specific size of each information block can be determined according to the size of the paging energy-saving configuration information corresponding to each terminal device group, and this application does not limit this.

[0150] In summary, the embodiment of the present application divides the paging group into multiple terminal device groups, further configures corresponding paging energy-saving configuration information for each terminal device group, and controls the reception of paging messages by terminal devices in units of terminal device groups, thereby achieving more refined control over the reception of paging messages by terminal devices, thereby improving energy-saving effects.
