[0038] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0039] Before describing the embodiments of the present application, a brief description of the relevant contents is given.

[0040] In order to save energy consumption of terminal equipment, both the long term evolution (LTE) system and the new radio (NR) system have a discontinuous reception (DRX) mechanism, which allows the terminal equipment to enter a discontinuous reception state without turning on the receiver when there is no data to receive, thereby achieving the purpose of power saving of the terminal equipment. The DRX mechanism includes configuring a DRX cycle for a terminal in the radio resource control connection (RRC_CONNECTED) state. A DRX cycle consists of an on duration and a DRX opportunity (Opportunity for DRX). During the DRX duration, the terminal equipment monitors and receives downlink channels and signals including the physical downlink control channel (PDCCH); during the "Opportunity for DRX" time, the terminal equipment does not receive downlink channels and signals such as PDCCH to reduce power consumption. Terminal devices in the RRC_idle state need to 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. In PO, terminal devices detect the PDCCH signal scrambled by the Paging Radio Network Temporary Identity (P-RNTI) to determine whether there is a paging message.

[0041] In the evolution of NR system, higher requirements are put forward for energy saving of terminal equipment. For example, for the existing DRX mechanism, during each on duration, the terminal equipment needs to continuously detect PDCCH to determine whether the network equipment schedules data transmission to itself. However, for most terminal equipment, there may be no need to receive data transmission for a long time, but it is still necessary to maintain a regular wake-up mechanism to monitor possible downlink transmission; there is room for further optimization of energy saving for such terminal equipment. The situation of receiving paging messages for terminal equipment in RRC_idle state is similar.

[0042] In version (R16), an energy-saving signal is introduced to further achieve energy saving of terminal devices. The energy-saving signal is used in combination with the DRX mechanism, and the terminal device receives an indication of the energy-saving wake-up signal before the DRX ON Duration. When the terminal device has data transmission within a DRX cycle, the energy-saving wake-up signal "wakes up" the terminal to monitor the PDCCH during the DRX On Duration; otherwise, when the terminal device has no data transmission within a DRX cycle, the energy-saving wake-up signal does not "wake up" the terminal, and the terminal does not need to monitor the PDCCH during the DRX On Duration. Compared with the existing DRX mechanism, when the terminal device has no data transmission, the terminal device can omit PDCCH monitoring during the DRX On duration, thereby achieving energy saving of the terminal device. The time of the terminal device outside the DRX On Duration is called the inactive time, and the time during the DRX On Duration is called the active time. The process of indicating whether the terminal device monitors the PDCCH during the DRX On Duration through the energy-saving signal, such as Figure 1 As shown, if the energy-saving signal indicates to monitor the PDCCH, the PDCCH is monitored during the DRX cycle; if the energy-saving signal indicates not to monitor the PDCCH, the PDCCH is not monitored during the DRX cycle.

[0043] In R16, the energy-saving signal is carried by the newly defined DCI format 2_6. The network device configures the terminal device to detect the search space set (search space set) of the PDCCH carrying DCI format 2_6. In the energy-saving signal, the number of bits required for each terminal device is up to 6. This includes 1 wake-up indication bit and up to 5 secondary cell sleep indication bits. The energy-saving signal can carry indication bits for multiple terminal devices to improve the efficiency of resource utilization within the system. Schematic diagram of the energy-saving signal carrying energy-saving indication information for multiple terminal devices, such as Figure 2 As shown, the network device notifies each terminal device of the starting position of the bit of the energy-saving indication information in the DCI, and the number of bits of each terminal device can be implicitly obtained through the configured number of secondary cell (carrier) groups; among them, the number of bits of the wake-up indication must not be zero, and the number of bits of the secondary cell (carrier) sleep indication can be 0. Furthermore, the network device can also notify the terminal device of the total number of bits of the DCI and the PS-RNTI of the scrambled PDCCH.

[0044] The monitoring timing of PDCCH is related to the time window of DRX On Duration. The network device configures a time offset (PS-offset) to determine the starting point of the PDCCH monitoring timing. After determining the starting point of the PDCCH monitoring timing, it is necessary to further determine the end point of the PDCCH monitoring; the end point of the PDCCH monitoring is determined by the device capabilities of the terminal device. The terminal device needs to perform operations such as device wake-up and initialization after wake-up within the minimum time interval before the DRX ON Duration. Therefore, the terminal device does not need to monitor the energy-saving wake-up signal within the minimum time interval before the DRX ON Duration. Terminal devices with faster processing speeds can use a shorter minimum time interval, such as "value 1" in Table 1 below; terminal devices with slower processing speeds need to use a longer minimum time interval, such as "value 2" in Table 1 below.

[0045] Table 1 Minimum time interval

[0046]

[0047] The energy-saving signal starts at the time position indicated by the PS-offset configured by the network device, and monitors the energy-saving signal within a complete PDCCH search space period after the starting point (defined by the parameter "duration" of the PDCCH search space), and the location of the monitored energy-saving signal is before the time period corresponding to the minimum time interval. Figure 3 As shown, the terminal device monitors the energy-saving signal marked by the dotted box at a monitoring time.

[0048] In the NR system, the network device can send paging to terminal devices in idle and connected states. The paging process can be triggered by the core network or by the network device, and is used to send a paging request to a terminal device in an idle state, or to notify system information updates, or to notify the terminal device to receive one or more of the following information such as Earthquake and Tsunami Warning System (ETWS) or Commercial Mobile Alert System (CMAS). After receiving the paging message from the core network, the network device parses the content therein, obtains the Tracking Area Identity (TAI) list of the terminal device, and performs air interface paging in the cells in the tracking area in the list under the TA list. The core network domain of the paging message is not decoded by the network device, but is transparently transmitted to the terminal device. After receiving the paging message sent by the core network, the network device aggregates the paging messages of the terminal devices with the same PO into one paging message, and transmits it to the relevant terminal devices through the paging channel. The terminal device receives paging parameters through system messages, and can determine the location of the common paging frame and paging opportunity of the cell, and calculate the location of the paging frame and paging opportunity of the terminal device in combination with its own terminal device identifier (UE_ID), and receive the paging message at the corresponding time. The paging message is carried by the Physical Downlink Shared Channel (PDSCH). The terminal device obtains the paging indication information by detecting the PDCCH encrypted by the P-RNTI, and thus receives the paging message. Terminal devices in idle state will save power through DRX, and the terminal device obtains DRX-related information from SIB2. The PO on the PF in a DRX cycle listens to the PDCCH encrypted by the P-RNTI to receive the paging message.

[0049] PF indicates the system frame number where the paging message appears, and PO indicates the time when the paging message may appear. A PF frame may include one or more POs. For each DRX cycle or paging cycle, the terminal device only needs to monitor its own PO. The PF system frame number (SFN) that satisfies the following formula can be used as a PF frame:

[0050] The SFN of PF is determined by the following formula:

[0051] (SFN + PF_offset)mod T = (T div N)*(UE_ID mod N) (1)

[0052] The index of the PO in a PF, Index_(i_s), is determined by the following formula:

[0053] i_s = floor (UE_ID / N)mod Ns (2)

[0054] Among them, T is the DRX cycle of the terminal device to receive Paging. The network device will broadcast a default DRX cycle (T_sib); if the network device configures a terminal device-specific DRX cycle (T_ue) for the terminal device through RRC signaling / high-layer signaling, the minimum of the DRX cycle broadcast by the network device and the terminal device-specific DRX cycle configured by RRC signaling / high-layer signaling is used as the DRX cycle of the terminal device, that is, T=min(T_sib, T_ue). If the network device does not configure a terminal device-specific DRX cycle for the terminal device through RRC signaling / high-layer signaling, the DRX cycle broadcast by the network device is used as the DRX cycle of the UE. N is the number of PFs contained in a DRX cycle. Ns is the number of POs contained in a PF, and PF-offset is the time domain offset used to determine the PF. UE_ID is 5G-S-TMSI mod 1024. Schematic diagram of the position of PF and PO in a DRX cycle, as shown Figure 4 shown.

[0055] For the PDCCH search space set, in the NR system, the network device indicates the PDCCH search space set to the terminal device, instructing the terminal device to detect the PDCCH on the corresponding time-frequency resources. The PDCCH search space is generally notified to the terminal device by the network device through RRC signaling. The configuration information of the search space set may include the following information:

[0056] (1) Search space ID;

[0057] (2) Control Resource Set Id, indicating the ID of the control resource set configuration, and configuring the time and frequency resources of the PDCCH search space;

[0058] (3) The period of the monitored slot and the offset within the period; currently NR supports periods of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 160, 320, 640, 1280, and 2560 slots;

[0059] (4) Duration indicates the number of slots monitored continuously within the PDCCH search space period;

[0060] (5) monitoringSymbolsWithinSlot, indicating which symbols within the PDCCH monitoring slot are used for PDCCH monitoring;

[0061] (6) P DCCH candidates, indicating the configuration information of PDCCH candidates;

[0062] (7) Search space type and DCI format, indicating whether the PDCCH search space is a common search space or a UE-specific search space, and the DCI format monitored under each type.

[0063] In summary, for terminal devices in idle state, the main power consumption comes from the periodic reception of paging messages, while the method for sending energy-saving signals to terminal devices in idle state, as well as the format, composition, and indication method of energy-saving indication information carrying energy-saving signals have not yet been clarified.

[0078] An optional processing flow of the paging indication method provided in the embodiment of the present application is as follows: Figure 6 As shown, the following steps are included:

[0079] Step S201: A terminal device receives energy-saving indication information in a first search space set, where the energy-saving indication information is used to indicate whether the terminal device needs to receive a paging message in a target paging occasion group or a target paging frame group.

[0080] In some embodiments, the terminal device receives energy-saving indication information sent by the network device in the first search space set. The target paging occasion group indicated by the energy-saving indication information may be a paging occasion group belonging to the terminal device, or a public paging occasion group; the target paging frame group indicated by the energy-saving indication information may be a paging frame group belonging to the terminal device, or the public paging frame group. The target paging occasion group includes at least one paging occasion, and the target paging frame group includes at least one paging frame.

[0081] In some embodiments, the target paging opportunity group or the target paging frame group may be predefined; or, the target paging opportunity group or the target paging frame group may be preconfigured; or, the target paging opportunity group or the target paging frame group may be configured via signaling, such as the target paging opportunity group or the target paging frame group may be configured via paging configuration information.

[0082] In some embodiments, the first search space set may be a common search space set; the first search set may be an existing search space set for receiving paging indication information (such as Type2-PDCCH CSS set), or an existing Type0-PDCCH CSS set, or an existing Type0A-PDCCH CSS set, or an existing Type1-PDCCHCSS set; in the case where the first search space set is an existing search space set, paging indication information is added on the basis of the information transmitted in the first search space set. The first search space set may also be a new search space set that is different from the existing Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCHCSS set, and the new search space set may be used only for transmitting energy-saving indication information.

[0083] In some embodiments, the energy saving indication information is carried in a first DCI, where the first DCI is a DCI format 1-0 scrambled by a P-RNTI, that is, DCI format 1-0.

[0084] In this scenario, the short message indication information of the first DCI and / or the bit information corresponding to the short message information can be used to indicate whether the terminal device needs to receive a paging message in the target paging timing group or the target paging frame group. The short message indication information of the first DCI can also be used to indicate that the first DCI carries energy-saving indication information.

[0085] In some other embodiments, the energy saving indication information is carried in the second DCI, where the second DCI is a DCI format 2-6 scrambled by PS-RNTI, that is, DCI format 2-6.

[0086] In this scenario, the wake-up indication bit information of the second DCI is used to indicate whether the terminal device needs to receive a paging message in the target paging occasion group or the target paging frame group. The secondary cell sleep indication bit information of the second DCI can also be used to indicate the target paging occasion group or the target paging frame group.

[0087] The above description is made for using bit information to indicate whether the terminal device needs to receive a paging message in a target paging time group or a target paging frame group. In a specific implementation, a bitmap may also be used to indicate whether the terminal device needs to receive a paging message in a target paging time group or a target paging frame group; the bit information of each bit in the bitmap is used to indicate whether the paging message needs to be received in the paging time group or the paging frame group corresponding to the bit. For example, each bit in the bitmap corresponds to a paging time group or a paging frame group; if the bit information of the bit is a first value (such as 0), it indicates that the terminal device does not receive the paging message in the paging time group or the paging frame group corresponding to the bit; if the bit information of the bit is a second value (such as 1), it indicates that the terminal device receives the paging message in the paging time group or the paging frame group corresponding to the bit. Of course, if the bit information of this bit is a first value (such as 1), it may indicate that the terminal device does not receive the paging message on the paging time group or paging frame group corresponding to this bit; if the bit information of this bit is a second value (such as 0), it may indicate that the terminal device receives the paging message on the paging time group or paging frame group corresponding to this bit.

[0088] For example, if there are multiple POs in a PF, the network device sends energy-saving indication information to the first PO among the multiple POs in the PF; when the terminal device in the cell receives the energy-saving indication information, if the energy-saving indication information indicates that there is no paging message, the terminal device determines that there is no paging message for other POs other than the first PO in the PF, or one or more PFs after the PF. It can be understood that the target paging occasion group indicated by the energy-saving indication information can be one or more paging occasions, and the target paging frame group can be one or more paging frames.

[0089] In some embodiments, if the first search space set is a search space set used only for receiving energy-saving indication information, the monitoring time of the terminal device to receive the energy-saving indication information in the first search space set is determined according to the paging opportunity or the paging frame. The paging frame can be a paging frame belonging to the terminal device or a public paging frame configured by the cell; the paging opportunity can be a paging opportunity belonging to the terminal device or a public paging opportunity configured by the cell. The monitoring time of the energy-saving indication information includes: the duration of the search space of the complete physical downlink control channel between the configured time offset and the minimum time interval before a paging frame or a paging opportunity. Figure 7 As shown, within the time offset before PO or PF, a duration in the search space of PDCCH with a minimum time interval from PO or PF is a monitoring opportunity for energy-saving indication information.

[0090] In some embodiments, the terminal device is Figure 7 The monitoring opportunity shown receives the energy saving indication information, Figure 7 The energy saving indication information may not be received at any time other than the monitoring time shown, or Figure 7 The energy saving instruction information is received at some time other than the indicated monitoring timing.

[0091] In an embodiment of the present application, the monitoring timing of the energy-saving indication information is determined according to PO or PF, rather than according to DRX OnDuration, so that the sending and receiving of the energy-saving indication information is more closely matched with the time when the terminal device actually receives the paging message, thereby achieving better energy-saving effects.

[0092] Another optional processing flow of the paging indication method provided in the embodiment of the present application is as follows: Figure 8 As shown, the following steps are included:

[0093] Step S301: The network device sends energy-saving indication information in a first search space set, where the energy-saving indication information is used to indicate whether the terminal device needs to receive a paging message in a target paging occasion group or a target paging frame group.

[0094] In some embodiments, the network device sends energy saving indication information to the terminal device in the first search space set.

[0095] In some embodiments, the description of the energy saving indication information, the first search space set, the target paging occasion group, and the target paging frame group is the same as that in the above step S201, and will not be repeated here.

[0096] The specific implementation process of the paging indication method provided in the embodiment of the present application is described in detail below using different formats of DCI carrying energy-saving indication information and different first search spaces.

[0097] Taking the DCI format 1-0 that carries the energy-saving indication information as an example, a detailed processing flow of the paging indication method provided in the embodiment of the present application is as follows: Fig. 9 As shown, the following steps are included:

[0098] Step S401: The terminal device receives DCI format1_0 carrying energy-saving indication information sent by a network device in a first search space set.

[0099] In some embodiments, the first search space set is an existing search space set for receiving paging indication information (such as Type2-PDCCH CSS set), Type2-PDCCH is used to indicate the scheduling information of PDSCH carrying paging messages, and Type2-PDCCH search space can be configured through RRC (such as pagingSearchSpace) signaling; information for configuring Type2-PDCCH search space can be carried in system messages or in dedicated signaling, for receiving paging messages on an activated BWP.

[0100] In this scenario, the DCI format 1-0 encrypted by P-RNTI can be used to carry the energy-saving indication information, that is, the energy-saving indication information is carried in the DCI format 1-0 encrypted by P-RNTI. In the prior art, the terminal device needs to detect the DCI format 1-0 encrypted by P-RNTI at the listening time of PDCCH; after detecting the DCI format 1-0 encrypted by P-RNTI, it needs to further receive the PDSCH to determine whether there is a paging message belonging to the terminal device. However, the embodiment of the present application carries the energy-saving indication information in the DCI format 1-0 encrypted by P-RNTI, so that after receiving the energy-saving indication information, the terminal device does not need to further receive the PDSCH, and can determine whether there is a paging message belonging to the terminal device by carrying the energy-saving indication information in the DCI format 1-0 encrypted by P-RNTI, so as to achieve the purpose of energy saving.

[0101] Here, only the example in which the first search space set is Type2-PDCCH CSS set is used for detailed explanation; in specific implementation, the first search space set may also be the existing Type0-PDCCH CSS set, or the existing Type0A-PDCCH CSS set, or the existing Type1-PDCCH CSS set, etc., and examples are not given one by one.

[0102] In this way, by using the existing search space set to transmit energy-saving indication information, the resource utilization of the control channel can be improved, and backward compatibility is good. By adding energy-saving indication information on the basis of transmitting the existing configuration information, the terminal device can know whether it needs to receive a paging message before its own PO arrives, which not only saves signaling overhead, but also avoids the power consumption caused by detecting a paging message when there is no paging message, thereby improving energy-saving gains.

[0103] In other embodiments, the first search space set is a search space set used only for receiving energy-saving indication information. The search space set used only for receiving energy-saving indication information is a new search space set that is different from the existing Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set and Type2-PDCCH CSS set.

[0104] Among them, for Type0-PDCCH CSS set: type0-PDCCH is used to indicate the scheduling information of PDSCH carrying SIB1, and its search space is indicated by the pdcch-ConfigSIB1 information field in the MIB information, which is used for the UE to receive SIB1 for initial access. After the UE receives SIB1, the CSS can also be configured through RRC signaling. The CRC of the DCIformat corresponding to Type0-PDCCH is scrambled by SI-RNTI.

[0105] For Type0A-PDCCH CSS set: type0A-PDCCH is used to indicate the scheduling information of PDSCH carrying OtherSystemInformation. Its search space is configured through RRC signaling, and its DCIformat CRC is scrambled by SI-RNTI.

[0106] For Type1-PDCCH CSS set: type1-PDCCH is used to indicate the scheduling information of PDSCH carrying RAR, its search space is configured through RRC signaling, and its CRC of DCI format is scrambled by RA-RNTI, MsgB-RNTI, or TC-RNTI.

[0107] For Type2-PDCCH CSS set: type2-PDCCH is used to indicate the scheduling information of PDSCH carrying paging messages. Its search space is configured through RRC signaling, and the CRC of its DCI format is scrambled by P-RNTI.

[0108] Through different CSSs, the terminal device can detect the PDCCH according to the control channel resource set of the PDCCH at the corresponding PDCCH monitoring time.

[0109] In some embodiments, regardless of whether the first search space set is a search space set used only for receiving energy-saving indication information, or any one of the existing Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set, the content carried by the P-RNTI-scrambled DCI format 1_0 carrying the paging indication information may be in the following form:

[0110] The P-RNTI scrambled DCI format 1_0 carries short message indication information (2 bits), short message information (8 bits), and scheduling information of the PDSCH carrying the paging message. The short message indication information indicates the content carried by the DCI, which may be shown in Table 2 below.

[0111] Table 2.Short Message indicator

[0112]

[0113]

[0114] In specific implementation, the reserved bit field may be used to carry the energy-saving indication information. For example, the bit information being "00" indicates that the DCI includes the energy-saving indication information.

[0115] Alternatively, a short message information is used to indicate the content carried by the DCI; the short message information is set to "10", and the short message information is used to indicate that the DCI includes energy-saving indication information. The content of the short message information may be as shown in Table 3 below, including a system message update indication, an ETWS and a CMAS indication, and an indication to stop monitoring PDCCH in the PO. In the short message information shown in Table 3, energy-saving indication information may also be carried to indicate a target paging occasion group or a target paging frame group, for example, by carrying energy-saving indication information through at least one of bits 4-8.

[0116] Table 3. Short Messages

[0117]

[0118] In some other embodiments, the target paging occasion group or the target paging frame group can be indicated by a bit map. The bit information of each bit in the bit map is used to indicate whether it is necessary to receive the paging message on the paging occasion group or paging frame group corresponding to the bit. For example, when the bit information of the first bit position is a first value (such as 0), it indicates that the paging message does not need to be detected in the paging occasion group or paging frame group corresponding to the first bit position; when the bit information of the first bit position is a second value (such as 1), it indicates that the paging message needs to be detected in the paging occasion group or paging frame group corresponding to the first bit position. Among them, the paging occasion group or paging frame group corresponding to the first bit position can be pre-agreed or pre-configured.

[0119] Step S402: The terminal device receives a paging message according to the energy-saving indication information.

[0120] In some embodiments, a schematic diagram of a terminal device receiving a paging message is shown as follows: Fig.10 As shown, the target paging period group indicated by the energy-saving indication information is the current PO. If the terminal device detects the energy-saving indication information at the PDCCH monitoring period of the current PO, the terminal device will no longer monitor the PDCCH at the remaining PDCCH monitoring periods of the current PO, that is, it will not receive or detect paging messages.

[0121] In some other embodiments, another schematic diagram of a terminal device receiving a paging message is as follows: Fig.11 As shown, the target paging frame group indicated by the energy-saving indication information is the current PF. If the terminal device detects the energy-saving indication information at the PDCCH monitoring opportunity of the current PO or PF, the terminal device will no longer monitor the PDCCH at the remaining PDCCH monitoring opportunities of the current PF, that is, it will not receive or detect paging messages. Alternatively, the target paging time group of the energy-saving indication information is one or more POs. If the terminal device detects the energy-saving indication information at the PDCCH monitoring opportunity of the current PO or PF, the terminal device will not monitor the PDCCH within the PO included in the target paging time group, that is, it will not receive or detect paging messages.

[0122] In some other embodiments, another schematic diagram of a terminal device receiving a paging message is shown as follows: Fig.12 As shown, the target paging frame group indicated by the energy-saving indication information is 2 PFs. The terminal device detects the energy-saving indication information at the PDCCH monitoring time of the current PO or PF. The terminal device does not monitor the PDCCH at the remaining PDCCH monitoring times of the current PF and the next PF, that is, it does not receive or detect the paging message.

[0123] Taking the DCI format 2-6 that carries the energy-saving indication information as an example, another detailed processing flow of the paging indication method provided in the embodiment of the present application is as follows: Fig.13 As shown, the following steps are included:

[0124] Step S501: The terminal device receives DCI format 2_6 carrying energy-saving indication information sent by the network device in the first search space set.

[0125] In some embodiments, the first search space set may be an existing search space set for receiving paging indication information (such as Type2-PDCCH CSS set). The network device may also configure the terminal device to detect the DCI format 1-0 (i.e., P-RNTI-scrambled DCI format 1-0) carrying the paging indication information while receiving the energy-saving indication information in the first search space set.

[0126] In this scenario, the terminal device detects the DCI format 2_6 encrypted by PS-RNTI in the first search space set based on the detection of the DCI format 1-0 encrypted by P-RNTI in the existing first search space set to obtain energy-saving indication information. In this way, by using the existing search space set to transmit the energy-saving indication information, the resource utilization of the control channel can be improved, and the backward compatibility is good. By adding energy-saving indication information on the basis of transmitting the existing configuration information, the terminal device knows whether it needs to receive a paging message before its own PO arrives, which not only saves the signaling overhead, but also avoids the power consumption caused by detecting the paging message when there is no paging message, thereby improving the energy-saving gain.

[0127] In other embodiments, the network device may configure a search space set, i.e., a first search space set, for the terminal device through a system message or dedicated signaling, which is only used to receive energy-saving indication information. The first search space set is a new search space set that is different from the existing Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set.

[0128] In this scenario, the terminal device receives the energy-saving indication information in an independently configured search space that is only used for receiving energy-saving indication information, which can avoid affecting the existing paging search space and reduce the impact on the terminal device's reception of paging messages; and, by using DCI format2_6, the existing energy-saving signals can be reused to reduce the complexity of implementation.

[0129] In some embodiments, regardless of whether the first search space set is a search space set used only for receiving energy-saving indication information, or any one of the existing Type0-PDCCH CSS set, Type0A-PDCCH CSS set, Type1-PDCCH CSS set, and Type2-PDCCH CSS set, the content carried by the RS-RNTI-scrambled DCI format2_6 carrying the paging indication information can be in the following form:

[0130] The wake-up indication bit information in the PS-RNTI-scrambled DCI format 2_6 can be used to indicate whether the terminal device needs to receive a paging message in the target paging time group or the target paging frame group. The secondary cell sleep indication bit information in the PS-RNTI-scrambled DCI format 2_6 can be used to indicate the target paging time group or the target paging frame group. For example, the value of the secondary cell sleep indication bit information in the PS-RNTI-scrambled DCI format 2_6 is 1, indicating that the target paging time group is the current PO, and the wake-up indication bit information in the PS-RNTI-scrambled DCI format 2_6 is 0, indicating that the paging message is not received in the target paging time group; then the terminal device does not monitor the PDCCH in the remaining PDCCH monitoring periods of the current PO, that is, does not receive or detect paging messages.

[0131] Step S502: The terminal device receives a paging message according to the energy-saving indication information.

[0132] In some embodiments, there is also a schematic diagram of a terminal device receiving a paging message, such as Fig.14 As shown, the energy saving indication information may indicate whether a paging message is received on a PO or PF.

[0133] In some other embodiments, there is another schematic diagram of a terminal device receiving a paging message, such as Fig.15 As shown, the energy saving indication information may indicate whether to receive paging messages on multiple POs or PFs.
