[0046] 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.

[0047] Before describing the embodiments of the present application, a brief description of the related contents is given.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The energy-saving signal is monitored within a complete PDCCH search space period (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 3As shown, the terminal device monitors the energy-saving signal marked by the dotted box at a monitoring time.

[0053] 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.

[0054] 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:

[0055] The SFN of PF is determined by the following formula:

[0056] (SFN + PF_offset)mod T = (T div N)*(UE_ID mod N) (1)

[0057] The index of the PO in a PF, Index_(i_s), is determined by the following formula:

[0058] i_s = floor (UE_ID / N)mod Ns (2)

[0059] 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.

[0060] 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:

[0061] (1) Search space ID;

[0062] (2) Control Resource Set Id, indicating the configuration ID of the control resource set and configuring the time and frequency resources of the PDCCH search space;

[0063] (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;

[0064] (4) Duration indicates the number of slots monitored continuously within the PDCCH search space period;

[0065] (5) monitoringSymbolsWithinSlot, indicating which symbols within the PDCCH monitoring slot are used for PDCCH monitoring;

[0066] (6) PDCCH candidates, indicating the configuration information of PDCCH candidates;

[0067] (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.

[0068] Terminal devices in idle state periodically receive paging messages at their own paging opportunities, but in actual situations, the probability of UE being paged may not be high; although terminal devices in idle state periodically detect PDCCH at paging opportunities, terminal devices in idle state do not detect the paging indication information sent to themselves, which will inevitably cause power waste. Similar to R16 for terminal devices in connected state, R17 optimizes the energy saving of terminal devices in idle state receiving paging messages and introduces similar energy-saving signals. One energy-saving signal is called Paging Early Indication (PEI), which is used to indicate whether the terminal device receives PDCCH at the target paging opportunity before the target paging opportunity arrives. Among them, the energy-saving signal can be a sequence-based signal or a PDCCH channel-based signal. If the PDCCH channel is used to carry the energy-saving signal, the existing PDCCH design scheme can be used to facilitate compatibility and multiplexing with existing systems and other channels. The energy-saving signal based on the PDCCH channel can also carry more energy-saving information, for example, it can carry terminal device sub-grouping information, which is used to indicate the terminal device sub-grouping corresponding to the energy-saving information. The terminal device sub-grouping is a further grouping of multiple terminal devices corresponding to a paging opportunity calculated by UE_ID. The sub-grouping information combined with the energy-saving information can more precisely indicate whether the terminal device needs to receive paging at the target paging opportunity. Among them, the energy-saving signal indicates whether one or more terminal devices receive paging on the corresponding PF or PO, as shown in the schematic diagram Figure 5 As shown, if the energy-saving signal indicates that a terminal device or a subgroup of terminal devices monitors PDCCH at PO or PF, then the terminal device or a subgroup of terminal devices monitors PDCCH at the PO or PF; if the energy-saving signal indicates that a terminal device or a subgroup of terminal devices do not monitor PDCCH at PO or PF, then the terminal device or a subgroup of terminal devices do not monitor PDCCH at the PO or PF.

[0069] For terminal devices in an idle state, the main power consumption is the periodic reception of paging messages; and the format of sending energy-saving signals to terminal devices in an idle state has not yet been clarified.

[0084] An optional processing flow of the energy-saving information determination method provided in the embodiment of the present application is as follows: Figure 7 As shown, the following steps are included:

[0085] Step S201, the terminal device determines the bit field size used to indicate energy-saving information in the downlink control information according to at least one of the following: terminal device grouping information corresponding to the energy-saving information, paging opportunity information corresponding to the energy-saving information, and first configuration information sent by the network device.

[0086] In some embodiments, the terminal device may be a terminal device in an RRC_idle state; the energy-saving information is used to indicate whether the terminal device receives a paging message at a target PO; wherein the energy-saving information may be a paging message corresponding to a plurality of terminal device groups, the energy-saving information may also be a paging message corresponding to a plurality of paging occasions, and the energy-saving information may also be a paging message corresponding to a plurality of paging occasion groups; receiving a paging message may be receiving a PDCCH carrying paging indication information and / or a PDSCH carrying a paging message.

[0087] In some embodiments, the terminal device grouping information corresponding to the energy-saving information may include at least one of the following: the number of terminal device groups corresponding to the energy-saving information and the bit field size of the energy-saving information corresponding to each terminal device group.

[0088] Among them, if the number of terminal device groups corresponding to the energy-saving information is N, the energy-saving information can indicate whether the terminal devices in the N terminal device groups receive paging messages or detect PDCCH at the target PO. For example, the energy-saving information may include N bit fields, each bit field indicating whether the terminal devices in a terminal device group receive paging messages or detect PDCCH at the target PO; the bit field size of the energy-saving information corresponding to each terminal device group may be the same or different.

[0089] In some embodiments, the information of the paging occasions corresponding to the energy-saving information may be the number of paging occasions corresponding to the energy-saving information, and the size of the bit field used to indicate the energy-saving information is related to the number of paging occasions or paging occasion groups corresponding to the energy-saving information.

[0090] In a specific implementation, if the terminal devices are not grouped, or only one terminal device is grouped, then one bit field of the energy-saving information may correspond to one paging opportunity or one paging opportunity group, or one bit field of the energy-saving information may correspond to at least two paging opportunities or at least two paging opportunity groups, or at least two bit fields of the energy-saving information may correspond to one paging opportunity or one paging opportunity group. For example, the energy-saving information includes X bit fields, each bit field corresponds to one paging opportunity or one paging opportunity group, that is, one bit field indicates whether the terminal device receives a paging message at one paging opportunity or one paging opportunity group. Alternatively, the energy-saving information includes X bit fields, each bit field corresponds to at least two paging opportunities or at least two paging opportunity groups, that is, one bit field indicates whether the terminal device receives a paging message at at least two paging opportunities or at least two paging opportunity groups. Alternatively, the energy saving information includes X bit fields, and at least two bit fields of the energy saving information may correspond to one paging occasion or one paging occasion group, that is, at least two bit fields indicate whether the terminal device receives a paging message at one paging occasion or one paging occasion group.

[0091] In a specific implementation, if the terminal device is divided into at least two terminal device groups, one bit field of the energy-saving information corresponding to each terminal device group corresponds to one of the paging opportunities or one of the paging opportunity groups; or, one bit field of the energy-saving information corresponding to each terminal device group corresponds to at least two of the paging opportunities or at least two of the paging opportunity groups; or, at least two bit fields of the energy-saving information corresponding to each terminal device group correspond to one of the paging opportunities or one of the paging opportunity groups. For example, the energy-saving information includes Y bit fields, and one bit field of the energy-saving information corresponding to each terminal device group corresponds to one of the paging opportunities or one of the paging opportunity groups, that is, one bit field indicates whether a terminal device group receives a paging message at one of the paging opportunities or one of the paging opportunity groups, and Y bit fields indicate whether a terminal device group receives a paging message at Y of the paging opportunities or Y of the paging opportunity groups. Alternatively, the energy-saving information corresponding to each terminal device group includes Y bit fields, and one bit field of the energy-saving information corresponding to each terminal device group corresponds to at least two paging occasions or at least two paging occasion groups, that is, one bit field indicates whether a terminal device group receives paging messages at least two paging occasions or at least two paging occasion groups, and Y bit fields indicate whether a terminal device group receives paging messages at least 2Y paging occasions or at least 2Y paging occasion groups. Alternatively, the energy-saving information corresponding to each terminal device group includes Y bit fields, and at least two bit fields of the energy-saving information corresponding to each terminal device group may correspond to one of the paging occasions or one of the paging occasion groups, that is, at least two bit fields indicate whether a terminal device group receives paging messages at one of the paging occasions or one of the paging occasion groups, and Y bit fields indicate whether a terminal device group receives paging messages at most Y / 2 paging occasions or at most Y / 2 paging occasion groups.

[0092] Among them, all terminal devices in a terminal device group follow the same paging message receiving strategy, that is, at a monitoring time or monitoring time group, all terminal devices in a terminal device group receive paging messages or do not receive paging messages.

[0093] In an optional implementation manner in which the energy-saving information corresponds to multiple paging occasions or paging occasion groups, the energy-saving 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] Optionally, the time period indicated by the time information corresponding to the paging energy saving indication information includes one or more paging frames PF and / or one or more paging occasions PO. For example, the time information corresponding to the paging energy saving indication information may indicate the number of PFs or POs.

[0098] Optionally, if the time period indicated by the time information corresponding to the paging energy-saving indication information includes a first time period, the terminal device considers that the PF and / or PO within the first time period corresponds to the paging energy-saving indication information, that is, the PF and / or PO within the first time period is the effective time corresponding to the paging energy-saving indication information. Furthermore, the terminal devices in the terminal device group receive or do not receive paging messages on one or more PFs or POs within the first time period according to the paging energy-saving indication information.

[0099] Optionally, in some embodiments, the time period indicated by the time information corresponding to the paging energy-saving indication information is a time period applicable to the paging energy-saving indication information corresponding to the terminal device group, or a common time period applicable to the paging energy-saving indication information corresponding to multiple terminal device groups.

[0100] That is, the valid time period of the paging energy-saving indication information corresponding to each terminal device group may be specific to each terminal device group (i.e., per UE group), or the valid time period of the paging energy-saving indication information corresponding to each terminal device group may be common, such as a common valid time period based on the cell configuration.

[0101] In some embodiments, the meaning of the time period indicated by the time information corresponding to the paging energy-saving indication information is predefined or configured by the network device. For example, the time period indicated by the time information corresponding to the paging energy-saving indication information included in the first information is predefined as a common valid time period, or the network device configures the time period indicated by the time information corresponding to the paging energy-saving indication information included in the first information as a common valid time period. As an example, the network device can configure the meaning of the time period indicated by the time information corresponding to the paging energy-saving indication information through paging configuration information.

[0102] In the embodiments of the present application, "pre-definition" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit the specific implementation method. For example, pre-definition can refer to what is defined in the protocol.

[0103] In the embodiment of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include but is not limited to the LTE protocol, the NR protocol, and related protocols used in future communication systems.

[0104] It should be understood that the embodiment of the present application does not limit the specific indication method of the time information corresponding to the paging energy-saving indication information.

[0105] As an example, the time information corresponding to the paging energy-saving indication information includes a first bit map, which includes multiple bits, each bit corresponds to a specific time period, and the different values ​​of each bit are used to indicate whether a paging message is received in the corresponding time period.

[0106] 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.

[0107] Optionally, in some embodiments, the time period corresponding to each bit includes at least one PF and / or at least one PO.

[0108] It should be understood that in some embodiments, the time information corresponding to the paging energy-saving indication information may also indicate an invalid time period corresponding to the content indicated by the paging energy-saving indication information. In this case, the terminal devices in the terminal device group may use the PF and PO corresponding to the terminal device group except for the invalid time period as the valid time period corresponding to the paging energy-saving indication information.

[0109] In another optional implementation manner in which the energy-saving information corresponds to multiple paging occasions or paging occasion groups, the energy-saving information corresponding to each terminal device group includes multiple paging energy-saving indication information and time information corresponding to each of the multiple paging energy-saving indication information.

[0110] 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 a valid time period corresponding to the content indicated by the paging energy-saving indication information.

[0111] The terminal devices in each terminal device group may 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.

[0112] 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.

[0113] There is also an optional implementation method for energy-saving information corresponding to multiple paging occasions or paging occasion groups. The energy-saving information corresponding to the terminal device group includes multiple paging energy-saving indication information, and each 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 each paging energy-saving indication information corresponds to a specific time period.

[0114] The terminal devices in each terminal device group may determine whether to receive a paging message within the valid time period according to a plurality of paging energy-saving indication information and the valid time periods respectively corresponding to the plurality of paging energy-saving indication information.

[0115] 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.

[0116] In some embodiments, the information of the paging occasion corresponding to the energy-saving information can be determined by the network device; the paging occasion corresponding to the energy-saving information is determined by the second configuration information sent by the network device, or the paging occasion corresponding to the energy-saving information is indicated by the DCI indicating the energy-saving information.

[0117] The following describes different implementation processes for a terminal device to determine the size of a bit field used to indicate energy-saving information in downlink control information.

[0118] Method 1: The terminal device determines the bit field size used to indicate the energy-saving information in the DCI according to the terminal device grouping information corresponding to the energy-saving information.

[0119] In some embodiments, the terminal device group information corresponding to the energy-saving information may include: the number of terminal device groups corresponding to the energy-saving information and the bit field size of the energy-saving information corresponding to each terminal device group; in this scenario, the bit field size used to indicate the energy-saving information in the DCI is the sum of the bit field sizes of the energy-saving information corresponding to all terminal device groups; for example, including M terminal device groups, the bit field size used to indicate the energy-saving information in the DCI is the sum of the bit field sizes of the energy-saving information corresponding to the M terminal device groups.

[0120] In some embodiments, the terminal device grouping may be configured by a network device, and the network device sends the terminal device grouping information to the terminal device. The number of terminal device groups may be 2, 4, 8, or 16. A schematic diagram of energy-saving information corresponding to N terminal device groups, such as Figure 8 As shown, the energy-saving information indicates whether N terminal device groups detect paging messages at the target paging opportunity. The bit field size of the energy-saving information corresponding to the N terminal device groups may be the same or different. For example, the bit field size of the energy-saving information corresponding to the first terminal device group and the second terminal device group is 2 bits, and the bit field size of the energy-saving information corresponding to the third terminal device group to the Nth terminal device group is 3 bits. Then, the bit field size used to indicate the energy-saving information is [4+(N-2)*3] bits.

[0121] Method 2: The terminal device determines the size of the bit field used to indicate the energy-saving information in the DCI according to the information of the paging occasion corresponding to the energy-saving information.

[0122] In some embodiments, the information of the paging occasion corresponding to the energy-saving information may be the number of paging occasions corresponding to the energy-saving information. The energy-saving information may be used to indicate whether the terminal device detects a paging message at one paging occasion, or a paging occasion group, or multiple paging occasions, or multiple paging occasion groups. In this scenario, the terminal devices may not be grouped or all terminal devices may be grouped as one terminal device, that is, the energy-saving information indicates whether all terminal devices detect a paging message at one paging occasion, or a paging occasion group, or multiple paging occasions, or multiple paging occasion groups. Alternatively, the energy-saving information only indicates whether a terminal device detects a paging message at one paging occasion, or a paging occasion group, or multiple paging occasions, or multiple paging occasion groups. A schematic diagram showing that the energy-saving information indicates that a terminal device does not detect a paging message at multiple paging occasions or paging frames, as shown in FIG. Fig. 9 As shown, the energy saving information instructs the terminal device not to detect the paging message in three paging occasions or paging frames after the energy saving information.

[0123] In some embodiments, the size of the bit field used to indicate the energy-saving information is related to the number of paging occasions or paging occasion groups corresponding to the energy-saving information. In a specific implementation, one bit field of the energy-saving information may correspond to one paging occasion or one paging occasion group, or one bit field of the energy-saving information may correspond to at least two paging occasions or at least two paging occasion groups, or at least two bit fields of the energy-saving information may correspond to one paging occasion or one paging occasion group. For example, the energy-saving information includes P bit fields, each bit field indicating whether the terminal device detects a paging message at one paging occasion or one paging occasion group; or, the energy-saving information includes P bit fields, each bit field indicating whether the terminal device detects a paging message at two or more paging occasions or paging occasion groups; or, the energy-saving information includes P bit fields, two or more bit fields indicating whether the terminal device detects a paging message at one paging occasion or one paging occasion group.

[0124] In an optional implementation, the DCI carries energy-saving information corresponding to multiple paging occasions, and can indicate whether the terminal device detects paging messages on multiple paging occasions or paging occasion groups in the form of a bitmap; if the value of a bit in the bitmap is "1", it indicates that the terminal device detects paging messages on the paging occasion or paging occasion group corresponding to the bit; if the value of a bit in the bitmap is "0", it indicates that the terminal device does not detect paging messages on the paging occasion or paging occasion group corresponding to the bit. If the number of paging occasions or paging occasion groups is X, and the energy-saving information corresponding to each occasion or occasion paging group is 1 bit, the size of the bit field used to indicate the energy-saving information is X bits.

[0125] In other optional implementations, the DCI carries energy-saving information corresponding to multiple paging occasions, and 2 bits may also be used to indicate whether 1, 2, 3, and 4 paging occasions or paging occasion groups detect paging messages in 4 consecutive paging occasions after the DCI carrying the energy-saving information. Here, if the number of paging occasions or paging occasion groups is 4, the bit field size for indicating the energy-saving information is 2 bits.

[0126] Method three: The terminal device determines the size of the bit field used to indicate the energy-saving information in the DCI according to the information of the paging occasion corresponding to the energy-saving information and the terminal device grouping information.

[0127] In some embodiments, the terminal device grouping information may be the number of terminal device groups; in the case of multiple terminal device groups, the terminal device may first determine the bit field size corresponding to each terminal device group based on the information of the paging opportunity corresponding to the energy-saving information, and then determine the bit field size in the DCI used to indicate the energy-saving information based on the number of terminal device groups. Among them, the processing process of the terminal device determining the bit field size corresponding to each terminal device group based on the information of the paging opportunity corresponding to the energy-saving information may be the same as the above-mentioned method 2; the process of the terminal device determining the bit field size in the DCI used to indicate the energy-saving information based on the number of terminal device groups may be the same as the above-mentioned method 1.

[0128] In some embodiments, the size of the bit field used to indicate the energy-saving information is related to the number of paging occasions or paging occasion groups corresponding to the energy-saving information. In a specific implementation, one bit field of the energy-saving information of each terminal device group may correspond to one paging occasion or one paging occasion group, or one bit field of the energy-saving information of each terminal device group may correspond to at least two paging occasions or at least two paging occasion groups, or at least two bit fields of the energy-saving information of each terminal device group may correspond to one paging occasion or one paging occasion group. For example, the energy-saving information includes P bit fields, each bit field indicating whether a terminal device in a terminal device group detects a paging message in a paging occasion or a paging occasion group; or, the energy-saving information includes P bit fields, each bit field indicating whether a terminal device in a terminal device group detects a paging message in two or more paging occasions or paging occasion groups; or, the energy-saving information includes P bit fields, two or more bit fields indicating whether a terminal device in a terminal device group detects a paging message in a paging occasion or a paging occasion group.

[0129] like Fig.10 As shown, among the P bit fields included in the energy-saving information, one bit field can indicate whether a terminal device in a terminal device group detects a paging message in a paging time group, that is, the first bit field in the P bit fields indicates whether the terminal devices in the first terminal device group detect a paging message in a paging time group, the second bit field in the P bit fields indicates whether the terminal devices in the second terminal device group detect a paging message in a paging time group, and so on. The Pth bit field in the P bit fields indicates whether the terminal devices in the Pth terminal device group detects a paging message in a paging time group.

[0130] In an optional implementation, the DCI carries energy-saving information for multiple terminal device groups, and the energy-saving information for each terminal device group includes energy-saving information for multiple paging occasions or paging frames. The bit domain size of the energy-saving information for multiple paging occasions or paging occasion groups is related to the number of paging occasions or paging frames corresponding to the energy-saving information.

[0131] The energy-saving information indicates whether a plurality of terminal devices are grouped to detect paging messages at a plurality of paging occasions, such as Fig.11 As shown, if a bitmap is used to indicate whether a terminal device group detects paging messages on multiple paging occasions or paging occasion groups, for example, the number of bits included in the bitmap is 6, then it can indicate whether a terminal device group detects paging messages on 6 paging occasions or paging occasion groups; for terminal device group 1, the 6 bits included in the bitmap respectively indicate whether the terminal devices in terminal device group 1 detect paging messages on paging occasions 1 to 6. The energy saving information indication method of terminal device group 2 to terminal device group N is the same as that of terminal device group 1.

[0132] Method 4: The terminal device determines the bit field size for indicating energy-saving information in the DCI according to the first configuration information sent by the network device, that is, the bit field size carrying the energy-saving information in the first configuration information.

[0133] In the embodiment of the present application, the DCI carrying the energy-saving information may be an existing DCI or a new DCI; wherein, the existing DCI may be an existing DCI used to carry the first information and also used to carry the energy-saving information; the first information may be at least one of the existing control information such as paging indication information, scheduling information of system messages, system message change indication and paging short messages; that is, the existing DCI carrying the first information is used to carry the energy-saving information. The new DCI may be a DCI used only to carry the energy-saving information, that is, the control information in the DCI is only used to indicate the energy-saving information; in addition to carrying the energy-saving information, the new DCI may also carry the first information, that is, the new DCI is used to carry the energy-saving information and the first information such as the paging indication information, scheduling information of the system messages, system message change indication and paging short messages; when the new DCI carries the energy-saving information and the first information, the format of the new DCI may be the same as or different from the format of the existing DCI carrying the first information.

[0134] In some embodiments, if the downlink control information is also used to carry the first information, part of the reserved bit field or all of the reserved bit field in the DCI can be used to carry the energy-saving information; or, the unused bit field in the DCI can be used to indicate the energy-saving information.

[0135] In some optional implementations, the first information is paging indication information, that is, the energy-saving information is carried by using the DCI carrying the paging indication information, then the DCI is DCI format 1_0, and the cyclic redundancy check (CyclicRedundancy Check, CRC) in the DCI can be scrambled by the paging radio network temporary identification (Paging-Radio Network TemporaryIdentity, P-RNTI). The DCI format 1_0 with CRC scrambled by P-RNTI carries indication information related to energy saving, which is used to indicate whether the terminal devices in one or more terminal device groups need to receive paging messages at the corresponding paging time or paging time group. When using the DCI carrying the paging indication information to carry the energy-saving information, the unused bit field in the DCI can be used to indicate the energy-saving information (that is, the first bit field in the short message field is used to indicate the energy-saving information), such as Table 1. Bits 4-8 in the short message field can be used to indicate energy-saving information.

[0136] Table 1. Short messages

[0137]

[0138] The reserved bit field in the DCI may also be used to indicate the energy-saving information (ie, the second bit field in the short message indicator field (Short Message indicator) is used to indicate the energy-saving information). For example, the reserved bit field "00" in Table 2 may be used to indicate the energy-saving information.

[0139] Table 2. Short message indication

[0140]

[0141] When the Short Message indicator field takes a value of 00, 8 bits in the short message field may be newly defined to carry multiple energy-saving signals. An implementation is shown in Table 3:

[0142] Table 3. Short messages

[0143] Bit Short Message 1 Energy saving signal 1, corresponding to terminal device group 1 2 Energy saving signal 2, corresponding to terminal device group 2 3 Energy saving signal 3, corresponding to terminal device group 3 4 Energy saving signal 4, corresponding to terminal device group 4 5 Energy saving signal 5, corresponding to terminal device group 5 6 Energy saving signal 6, corresponding to terminal device group 6 7 Energy saving signal 7, corresponding to terminal device group 7 8 Energy saving signal 8, corresponding to terminal device group 8

[0144] In some embodiments, the DCI format 1_0 using the P-RNTI to scramble the CRC includes a 6-bit reserved bit field, and part of or all of the reserved bit field may also be used to carry energy-saving information.

[0145] In some optional implementations, the first information is the scheduling information of the system message, that is, the DCI carrying the scheduling information of the system message is used to carry the energy-saving information, then the DCI is DCI format 1_0, and the CRC in the DCI can be scrambled by the system message radio network temporary identifier (System Information-Radio Network Temporary Identity, SI-RNTI). The DCI format 1_0 with the CRC scrambled by SI-RNTI may include a 15-bit reserved bit field, and part of the reserved bit field or all of the reserved bit field in the reserved bit field can also be used to carry energy-saving information.

[0146] The embodiment of the present application utilizes the existing DCI to carry energy-saving information, so that when the network device sends energy-saving information to the terminal device, the network device does not need to send additional information to the terminal device, thereby saving network resources.

[0147] In some embodiments, if the DCI carrying the energy-saving information is a new DCI, the new DCI can be used only to carry the energy-saving information, that is, the control information in the DCI is only used to indicate the energy-saving information; in addition to carrying the energy-saving information, the new DCI can also carry existing control information such as paging indication information, scheduling information of system messages, system message change indications, and paging short messages; the new DCI can have DCI format 1-0, or DCI format 2-6, and the CRC in the new DCI can be encrypted in a different manner from the CRC in the existing DCI, such as the CRC in the new DCI can be encrypted with PPS-RNTI. The present application does not limit the format of the new DCI, and the new DCI can have a new DCI format.

[0148] In some embodiments, the energy saving information determination method may further include:

[0149] Step S202: The terminal device determines the position of the energy-saving information in the downlink control information.

[0150] In some embodiments, the terminal device can determine the size of the bit field used to indicate the energy-saving information in the DCI according to any one of the methods 1 to 4 in the above step S201. The terminal device can determine the terminal device group to which it belongs according to its own identification (UE-ID) and predefined rules; the terminal device can determine the location of the energy-saving information corresponding to the terminal device in the DCI according to the number of terminal device groups preset or indicated by the network device and / or the number of paging occasions or paging occasion groups corresponding to the energy-saving information in each terminal device group.

[0151] For example, the terminal device determines, based on the indication of the network device, that there are six terminal device groups, and the energy-saving information corresponding to each terminal device group is one bit. The terminal device determines that the terminal device belongs to the second terminal device group based on its own identification and predefined rules; the terminal device determines that the bit field size used to indicate the energy-saving information in the DCI is six bits, and the second bit is used to indicate whether the terminal device group described by the terminal device detects a paging message at the target paging opportunity.

[0152] It should be noted that in an embodiment of the present application, DCI can be carried on PDCCH, and detecting paging messages can also be called detecting PDCCH carrying paging indication information and / or PDSCH carrying paging messages. The paging opportunity group includes at least two paging opportunities. All paging opportunities in a paging opportunity group can belong to one paging frame or to at least two adjacent paging frames; terminal device grouping can also be called terminal device sub-grouping (sub-grouping) or paging sub-group.

[0153] Another optional processing flow of the energy-saving information determination method provided in the embodiment of the present application is as follows: Fig.12 As shown, the following steps are included:

[0154] Step S301, the network device sends second information to the terminal device, and the second information is used by the terminal device to determine the bit field size used to indicate energy-saving information in the downlink control information; the second information includes at least one of the following: terminal device grouping information corresponding to the energy-saving information, paging opportunity information corresponding to the energy-saving information, and first configuration information.

[0155] In some embodiments, the terminal device may be a terminal device in RRC_idle state; the energy saving information is used to indicate whether the terminal device receives a paging message at the target PO before the target PO arrives, wherein receiving the paging message may be receiving a PDCCH carrying paging indication information and / or a PDSCH carrying a paging message.

[0156] In some embodiments, the description of the terminal device grouping information corresponding to the energy-saving information, the paging opportunity information corresponding to the energy-saving information, and the first configuration information is the same as that in step S201 and will not be repeated here.

[0157] The energy-saving information determination method provided in the embodiment of the present application enables the terminal device to determine the bit field size used to indicate the energy-saving information in the DCI according to the terminal device grouping information corresponding to the energy-saving information, the information of the paging opportunity corresponding to the energy-saving information, and the first configuration information sent by the network device. After determining the bit field size used to indicate the energy-saving information in the DCI, the position of the energy-saving information corresponding to the terminal device in the DCI can be further determined, so that the terminal device can accurately receive the energy-saving information corresponding to itself; the terminal device can determine whether to receive the paging message at the target paging opportunity through the received energy-saving information, thereby realizing energy saving of the terminal device.

[0184] In some embodiments, the processing unit 601 is further configured to determine a position of the energy-saving information in the downlink control information.
