[0054] 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.

[0055] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0056] 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.

[0058] 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.

[0059] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.

[0060] To facilitate a better understanding of the embodiments of the present application, the CSI-RS and TRS in the NR system related to the present application are described.

[0061] CSI-RS in NR is mainly used in the following aspects:

[0062] 1. Obtain channel state information. Used for scheduling, link adaptation, and multiple-in-multiple-out (MIMO)-related transmission settings.

[0063] 2. Used for beam management. The shaping weights of the beams at the UE and base station sides are obtained to support the beam management process.

[0064] 3. Time-frequency tracking: This is achieved by setting TRS in the system.

[0065] 4. Used for mobility management. The system completes the measurement requirements related to UE mobility management by tracking the CSI-RS signals of the current cell and neighboring cells.

[0066] 5. Used for rate matching: The rate matching function at the resource element (RE) level of the data channel is completed by setting the zero-power CSI-RS signal.

[0067] In the NR system, in order to flexibly support the virtualization mapping of different antennas and the design of codebooks, and taking into account the actual application deployment scenarios, the number of ports supported by NR is 1, 2, 4, 8, 12, 16, 24, and 32. Among them, the 8, 12, 16, 24, and 32 port patterns are all composed of 2 or 4 port patterns. The CSI-RS of different antenna ports are multiplexed to form CSI-RS patterns by frequency division, time division, or code division. Each X-port CSI-RS pattern basic unit consists of Y adjacent REs in the frequency domain and Z adjacent symbols in the time domain within a physical resource block (PRB).

[0068] 1 port: (Y, Z) = (1, 1);

[0069] 2-port: (Y, Z) = (2, 1);

[0070] 4-port: (Y,Z) = (4,1) or (2,2).

[0071] For example, the CSI-RS of 12 antenna ports defines two patterns, such as Figure 2 As shown, pattern 1 includes 6 code division multiplexing (CDM) 2 groups, each CDM2 group includes 2 REs (frequency domain (FD)) on 1 symbol (time domain (TD)), and the CSI-RS of two antenna ports are code-division multiplexed. Pattern 2 includes 3 CDM4 groups, each CDM4 group includes 4 REs (FD) on 2 symbols (TD), and the CSI-RS of 4 antenna ports are code-division multiplexed.

[0072] NR supports periodic, semi-continuous and non-periodic resource configuration. CSI-RS is a UE-specific configuration. Considering the resource overhead of CSI-RS, the network often configures a set of CSI-RS resources to multiple UEs for sharing when configuring CSI-RS. The UE performs rate matching on the REs occupied by the configured CSI-RS. For example, if the resource allocation of the Physical Downlink Shared Channel (PDSCH) includes REs for CSI-RS configured by the network, these REs are punctured and do not carry PDSCH.

[0073] In order to enable UE to track and compensate for the time offset and frequency offset of the downlink channel, the NR system defines a new reference signal for time and frequency tracking, called the TRS signal, which is essentially a CSI-RS.

[0074] The NR system supports periodic and non-periodic TRS. Periodic TRS is a CSI-RS resource set that contains multiple periodic CSI-RS resources, and this resource set configuration contains a high-level signaling indicating that this resource set is used as TRS. In order to achieve a certain time tracking range, each CSI-RS resource is a 1-port CSI-RS resource with a density of 3. At the same time, in order to achieve the frequency tracking range, the TRS symbol interval in a time slot is 4. TRS only supports 1 port, so all non-zero power channel state information reference signal (Non-Zero Power Channel State Information-Reference Signal, NZP-CSI-RS) resources configured in the CSI-RS resource set contain the same port index and correspond to the same antenna port.

[0075] For the low frequency band, the upper layer configures a CSI-RS resource set containing 4 periodic CSI-RS resources for the UE. These 4 resources are distributed in two consecutive time slots. Each time slot contains two periodic CSI-RS resources, and the CSI-RS resources in these two time slots have the same position in the time domain.

[0076] For the high frequency band, the upper layer configures the UE with a CSI-RS resource set containing 2 periodic CSI-RS resources distributed in 1 time slot, or configures a CSI-RS resource set containing 4 periodic CSI-RS resources distributed in 2 consecutive time slots, and the CSI-RS resources in these two time slots have the same position in the time domain.

[0077] There are many non-periodic times and some periodic events in the system that cannot be aligned with the periodic TRS, which will have a serious impact on the demodulation of the UE. In addition, after the beam in the high frequency band is changed, it cannot be received for a long time and time-frequency tracking cannot be performed according to TRS. Therefore, it is necessary to introduce non-periodic TRS signals on the basis of periodic TRS. The structure of non-periodic TRS is the same as that of periodic TRS, such as using the same bandwidth, having the same frequency domain position and the same number of time slots in a TRS cluster (burst). Considering the consistency with the triggering method of non-periodic CSI-RS, NR uses downlink control information (Downlink Control Information, DCI) to trigger non-periodic TRS.

[0078] In order to facilitate a better understanding of the embodiments of the present application, the terminal energy-saving technology related to the present application is explained.

[0079] In the evolution of NR technology, higher requirements are put forward for UE power saving. For example, for the existing discontinuous reception (DRX) mechanism, during each activation period (On Duration), the UE needs to continuously detect the physical downlink control channel (PDCCH) to determine whether the base station schedules data transmission to itself. However, for most UEs, 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 transmissions. For such UEs, there is room for further optimization of power saving. The situation is similar for UEs in the idle state of Radio Resource Control (RRC) receiving paging messages.

[0080] In the Release 16 (R16) standard, an energy-saving signal is introduced to achieve further energy saving. The energy-saving signal is used in conjunction with the DRX mechanism, and the terminal receives an indication of the energy-saving wake-up signal before the DRX ON duration. When the terminal has data transmission in 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 has no data transmission in 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. When the terminal has no data transmission, the terminal can omit PDCCH monitoring during the DRX Onduration, thereby achieving energy saving. The time of the terminal outside the DRX On duration is called the inactive time, and the time in the DRX On Duration is called the active time.

[0081] In the NR system, the network can send paging to UEs in idle and connected states. The paging process can be triggered by the core network or the base station, and is used to send a paging request to the UE in the idle state, or to notify the system information update, and to notify the UE to receive information such as the Earthquake and Tsunami Warning System (ETWS) and the Commercial Mobile Alert System (CMAS). After receiving the paging message from the core network, the base station interprets the content, obtains the Tracking Area Identity (TAI) and Tracking Area List (TA list) of the UE, and performs air interface paging in the cells belonging to the tracking areas in the list. The core network domain of the paging message will not be decoded in the base station, but will be transparently transmitted to the UE. After receiving the paging message from the core network, the base station aggregates the paging messages of the UEs with the same paging occasion (PO) into one paging message and transmits it to the relevant UEs through the paging channel. The UE receives paging parameters through system messages, calculates PO based on its own terminal identity (UE_ID), and receives paging messages at the corresponding time. Paging messages are carried by PDSCH, and the UE obtains paging indication information by detecting the PDCCH scrambled with the Paging Radio Network Temporary Identity (P-RNTI), thereby receiving paging messages. UEs in idle state will save power through DRX, and the UE obtains DRX-related information from the System Information Block (SIB) 2. The PO on the paging frame (PF) in a DRX cycle listens to the PDCCH scrambled by P-RNTI to receive paging messages.

[0082] PF indicates the system frame number on which the paging message should appear, and PO indicates the possible time when it may appear. A PF frame may include one or more POs. In each DRX cycle or paging cycle, the UE only needs to monitor its own PO. A system frame number (SFN) that satisfies the following formula 1 can be used as a PF frame:

[0083] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) Formula 1

[0084] In PF, the index of PO corresponding to UE_ID, i.e., i_s, can be calculated according to the following formula 2.

[0085] i_s=floor(UE_ID / N) mod Ns Formula 2

[0086] Among them, T represents the DRX cycle of the UE. If the default DRX cycle indicated in the system message is recorded as T_sib, if the UE's DRX value T_ue has been configured, then T = min (T_ue, T_sib); if T_ue is not configured, the default value indicated in the system message is used, T = T_sib. UE_ID = (5G-S-TMSI mod 1024). N is the number of PFs in T. Ns is the number of POs in a PF. PF_offset is used to determine the frame offset of PF. 5G-S-TMSI is the 5G serving temporary mobile user identity (Serving-Temporary Mobile Subscriber Identity, S-TMSI). Figure 3 As shown, the position of PF within a DRX cycle, and the position of PO within PF.

[0087] For terminal devices in RRC connection state, time-frequency tracking can be performed through the configured CSI-RS, TRS and other reference signals. For terminal devices in idle or deactivated state, the terminal devices also need to perform time-frequency tracking and automatic gain control (AGC) before their corresponding PO detection paging. Since terminal devices in idle or deactivated state are not configured with CSI-RS, TRS and other reference signals, CSI-RS and TRS need to be introduced for terminal devices in idle or deactivated state. However, how to indicate CSI-RS and TRS resources for terminal devices in idle or deactivated state is a problem that needs to be solved.

[0088] Based on the above problems, the present application proposes a solution for configuring a reference signal, whereby a network device can configure resource information of a reference signal and / or monitoring timing information of a reference signal for a terminal device in an idle state or a deactivated state, so that the terminal device in an idle state or a deactivated state can perform time-frequency tracking and automatic gain control before detecting a paging at its corresponding paging timing.

[0089] The technical solution of the present application is described in detail below through specific embodiments.

[0090] Figure 4 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, such as Figure 4 As shown, the method 200 may include at least part of the following contents:

[0091] S210, the network device sends a common PDCCH to a terminal device in an idle state or a deactivated state, wherein the target information carried in the common PDCCH is used to indicate at least one of the following: resource information of a reference signal, and monitoring opportunity information of a reference signal;

[0092] S220, the terminal device receives the public PDCCH sent by the network device.

[0093] In an embodiment of the present application, the network device indicates the resource information of the reference signal and / or the monitoring timing information of the reference signal to the terminal device in the idle state or the deactivated state through the target information carried in the public PDCCH, thereby avoiding configuring a new PDCCH search space for the terminal device in the idle state or the deactivated state to indicate the relevant parameters of the reference signal, reducing system overhead and having good backward compatibility.

[0094] Optionally, the reference signal includes but is not limited to at least one of the following:

[0095] CSI-RS, TRS.

[0096] For terminal devices in idle or deactivated states, before their corresponding PO detection paging, time-frequency tracking and automatic gain control can be performed based on reference signals such as CSI-RS and TRS, so as to restore time-frequency synchronization before PO arrives, and then receive PDCCH and PDSCH during PO.

[0097] It should be noted that the type of the search space of the public PDCCH is a public search space, and a terminal device in an idle state or a deactivated state can also receive the public PDCCH through the public search space.

[0098] The public PDCCH is described in detail below through Example 1 and Example 2.

[0099] Example 1: the common PDCCH is a Type 0 PDCCH (Type0-PDCCH).

[0100] Type0-PDCCH can be used to indicate the scheduling information of PDSCH carrying SIB1. Its search space is indicated by the PDCCH configuration SIB1 (pdcch-ConfigSIB1) information field in the master information block (MIB) information, which is used for terminal devices to receive SIB1.

[0101] Optionally, the format of the DCI is DCI format 1_0 (DCI format 1_0), and the DCI is scrambled by a system information radio network temporary identifier (System Information Radio Network Temporary Identity, SI-RNTI).

[0102] For example, the SI-RNTI scrambles the cyclic redundancy check (CRC) of the DCI format 1_0.

[0103] Optionally, the content carried in DCI format 1_0 of SI-RNTI scrambled CRC is as follows:

[0104] Frequency domain resource allocation information;

[0105] Time domain resource allocation information;

[0106] Mapping of virtual resource blocks to physical resource blocks;

[0107] Modulation coding method;

[0108] Redundant version;

[0109] System message type indication;

[0110] Reserved bit.

[0111] Among them, the reserved bits include 15 bits.

[0112] Optionally, in Example 1, the target information is part or all of the reserved bits in the DCI carried by the common PDCCH.

[0113] For example, several bits in the reserved bits are defined to indicate resource information of CSI-RS and TRS.

[0114] Optionally, in Example 1, the period of the monitoring opportunity of the common PDCCH is related to the multiplexing pattern of the control resource set and the synchronization signal block (Synchronization Signal Block, SSB).

[0115] For example, for multiplexing pattern 1, the period of monitoring opportunities of the common PDCCH is 20 ms, that is, 2 radio frames.

[0116] For another example, for multiplexing pattern 2 or 3, the period of the monitoring opportunity of the common PDCCH is the same as the period of the SSB.

[0117] Example 2: the common PDCCH is a Type 2 PDCCH (Type2-PDCCH).

[0118] Type2-PDCCH can be used to indicate the scheduling information of the PDSCH carrying the paging message. The search space set of Type2-PDCCH is configured in SIB1 and can be configured as a separate search space set or the same as the search space set of Type0-PDCCH.

[0119] Optionally, in Example 2, the format of the DCI is DCI format 1_0 (DCI format1_0), and the DCI is scrambled by a paging radio network temporary identifier (Paging Radio Network Temporary Identity, P-RNTI).

[0120] For example, the P-RNTI scrambles the CRC of DCI format 1_0.

[0121] Optionally, the content carried in the DCI format 1_0 of the P-RNTI scrambled CRC is as follows:

[0122] Short message indicator;

[0123] Short message;

[0124] Frequency domain resource allocation information;

[0125] Time domain resource allocation information;

[0126] Mapping of virtual resource blocks to physical resource blocks;

[0127] Modulation coding method;

[0128] Transport block scaling;

[0129] Reserved bits.

[0130] Optionally, in Example 2, the target information includes but is not limited to at least one of the following:

[0131] Some or all of the reserved bits in the DCI carried by the common PDCCH;

[0132] At least one bit in the short message indication information in the DCI carried by the common PDCCH;

[0133] At least one bit in a short message in the DCI carried by the common PDCCH.

[0134] Optionally, in Example 2, the resource information or monitoring opportunity information of the reference signal may be indicated by a number of bits in the reserved bits. A new short message type may also be defined for indication. Specifically, the P-RNTI scrambled DCI format 1_0 carries short message indicator information (2 bits) and short message (8 bits).

[0135] Among them, the short message indicator information indicates the content carried by the DCI, as shown in Table 1 below.

[0136] Table 1

[0137] Bit Short message indicator 00 Reserved 01 DCI only includes scheduling information for paging 10 DCI only includes short messages 11 DCI includes scheduling information and short messages for paging.

[0138] In order to carry the resource information or monitoring opportunity information of the reference signal through the P-RNTI scrambled DCI format 1_0, the short message indication information can be set to 00 to distinguish it from the other three types of information. Or the short message indication information can be set to 10 to further indicate the resource information or monitoring opportunity information of the reference signal through a short message.

[0139] The content of the short message is shown in Table 2 below, including a system message update indication, an ETWS and CMAS indication, and an indication to stop monitoring PDCCH in PO. Bits 4 to 8 of the short message may be used to indicate resource information or monitoring opportunity information of a reference signal.

[0140] Table 2

[0141]

[0142] Optionally, in some embodiments, the resources corresponding to the resource information of the reference signal are shared with the terminal device in the connected state. That is, the resources of CSI-RS and TRS corresponding to the terminal device in the idle state or deactivated state are shared with the terminal device in the RRC connected state. Thus, the resource overhead of CSI-RS and TRS can be reduced.

[0143] Optionally, in some embodiments, when the target information is at least used to indicate resource information of a reference signal, the target information is specifically used to indicate that one or more resources in a first reference signal resource set are reference signal resources, or the target information is specifically used to indicate that one or more reference signal resource sets in a reference signal resource configuration are reference signal resources.

[0144] Optionally, the first reference signal resource set is obtained from system information sent by the network device. For example, the terminal device obtains the first reference signal resource set from SIB1 in the system information sent by the network device. In this case, the number of bits occupied by the target information depends on the number of resources included in the first reference signal resource set, or the target information occupies a fixed number of bits.

[0145] Optionally, the reference signal resource configuration is obtained from the system information sent by the network device. For example, the terminal device obtains the reference signal resource configuration from SIB1 in the system information sent by the network device. In this case, the number of bits occupied by the target information depends on the number of reference signal resource sets included in the reference signal resource configuration, or the target information occupies a fixed number of bits. For example, the CSI-RS resource configuration may include one or more NZP-CSI-RS resource sets, and an NZP-CSI-RS resource set includes one or more NZP-CSI-RS resources, including the period of the CSI-RS resource, the position of RE in a PRB, the symbol in the time slot, etc.; the reference signal resource indication information may indicate the NZP-CSI-RS resource set ID, or the NZP-CSI-RS resource ID.

[0146] It should be noted that, when the NZP-CSI-RS resource set is configured as TRS, the corresponding reference signal resource indication information may indicate the resources of TRS.

[0147] Optionally, the resource type of the reference signal indicated by the target information includes at least one of the following:

[0148] Periodic, non-periodic, and semi-continuous scheduling.

[0149] Optionally, in an embodiment of the present application, the terminal device monitors the reference signal according to the resource information of the reference signal indicated by the target information, or the terminal device monitors the reference signal according to the resource information of the reference signal indicated by the target information and the monitoring time interval.

[0150] Accordingly, the network device may send a reference signal according to the resource information of the reference signal indicated by the target information, or the network device may send a reference signal according to the resource information of the reference signal indicated by the target information and the monitoring time interval.

[0151] Optionally, the monitoring time interval is pre-configured or agreed upon by a protocol, or the monitoring time interval is configured by information carried in the public PDCCH.

[0152] For example, Figure 5As shown, at the public PDCCH monitoring opportunity, the terminal device detects the public PDCCH, and obtains the resource information of the reference signal based on the target information carried in the public PDCCH. The terminal device can monitor the reference signal within a monitoring time interval of the reference signal, such as a monitoring time interval within the time interval after the public PDCCH monitoring opportunity and before the next public PDCCH monitoring opportunity. Of course, the monitoring time interval may not exist, and the terminal device always receives the reference signal resources indicated by the resource information of the reference signal.

[0153] Optionally, in some embodiments, when the target information is at least used to indicate monitoring opportunity information of a reference signal, the target information is specifically used to instruct the terminal device to monitor one or more monitoring opportunities of the reference signal.

[0154] Optionally, in a case where the target information is at least used to indicate monitoring timing information of a reference signal, the terminal device receives system information sent by the network device, where the system information is used to semi-statically configure resource information of the reference signal.

[0155] In other words, the network equipment can semi-statically configure some CSI-RS, TRS and other reference signal resources for use by terminal devices in idle or deactivated states and connected states. This resource configuration does not need to be frequently changed for terminal devices in idle or deactivated states, thereby avoiding additional power consumption of terminal devices caused by frequent reception.

[0156] Optionally, the monitoring timing information of the reference signal indicated by the target information is determined according to the periodic information in the resource information of the reference signal configured by the system information. That is, the monitoring timing of reference signals such as CSI-RS and TRS can be determined according to the periodic information in the resource information of reference signals such as CSI-RS and TRS.

[0157] Furthermore, the terminal device can determine the resources and timing for receiving the reference signal based on the monitoring timing information of the reference signal indicated by the target information and the resource information of the reference signal configured by the system information, and / or determine the timing for not receiving the reference signal in the resource information of the reference signal configured by the system information.

[0158] Accordingly, the network device can determine the resources and timing for sending the reference signal based on the monitoring timing information of the reference signal indicated by the target information and the resource information of the reference signal configured by the system information, and / or determine the timing for not sending the reference signal in the resource information of the reference signal configured by the system information.

[0159] For example, in the case where the target information is at least used to indicate the monitoring timing information of the reference signal, the target information may indicate that the terminal device receives the reference signal at the first monitoring timing after receiving the common PDCCH carrying the target information, or the target information may indicate that the terminal device receives the reference signal at several monitoring timings after receiving the common PDCCH carrying the target information, wherein the monitoring timing information may include the number of monitoring timings. The terminal device may determine the timing and resources for receiving the reference signal based on the monitoring timing information of the reference signal indicated by the target information and the resource information of the reference signal indicated in the system message, thereby receiving the reference signal. In addition, the terminal device may not receive the reference signal at other monitoring timings determined in the resource information of the reference signal, thereby achieving the purpose of saving power.

[0160] Optionally, the terminal device may monitor the reference signal according to the monitoring timing information of the reference signal indicated by the target information, or the terminal device may monitor the reference signal according to the monitoring timing information and the monitoring time interval of the reference signal indicated by the target information.

[0161] Accordingly, the network device may send the reference signal according to the monitoring timing information of the reference signal indicated by the target information, or the network device may send the reference signal according to the monitoring timing information and the monitoring time interval of the reference signal indicated by the target information.

[0162] Therefore, the monitoring of reference signals can be reduced, thereby achieving the purpose of power saving for the terminal.

[0163] Optionally, the monitoring time interval is pre-configured or agreed upon by a protocol, or the monitoring time interval is configured by information carried in the public PDCCH.

[0164] For example, Figure 6 As shown, at the public PDCCH monitoring time, the terminal device detects the public PDCCH, and obtains the monitoring time information of the reference signal based on the target information carried in the public PDCCH, and the terminal device can monitor the reference signal within a monitoring time interval of the reference signal. Of course, the monitoring time interval may not exist, and the terminal device always receives the reference signal according to the monitoring time information of the reference signal.

[0165] Optionally, in some embodiments, the terminal device may determine a monitoring time of the public PDCCH according to a search space set of the public PDCCH.

[0166] Optionally, in some other embodiments, the terminal device determines the monitoring timing of the public PDCCH based on the search space set and the first indication information of the public PDCCH, wherein the first indication information is used to indicate part of the monitoring timing of the public PDCCH, or the first indication information is used to determine part of the monitoring timing of the public PDCCH.

[0167] Optionally, the first indication information may be a period scaling factor and an offset value. In this case, the first indication information may be used to determine part of the monitoring opportunities of the public PDCCH, and the first indication information may be used to expand the period of the public PDCCH monitoring opportunity, determine the monitoring opportunity after the expanded period, and thus reduce the public PDCCH monitoring opportunity.

[0168] For example, Figure 7 As shown, the terminal device determines the monitoring time of the common PDCCH according to the search space set of the common PDCCH. At other monitoring times in the monitoring period of the common PDCCH, the terminal device does not require detection to obtain relevant information of the reference signal.

[0169] Optionally, the first indication information is obtained from system information sent by the network device, or the first indication information is obtained from the public PDCCH.

[0170] It should be noted that if the first indication information is obtained from the public PDCCH, the terminal device can blindly detect the public PDCCH. After detecting the public PDCCH, it can determine the monitoring timing of the public PDCCH based on the first indication information obtained from the public PDCCH and the search space set of the public PDCCH.

[0171] Therefore, the monitoring of the common PDCCH carrying target information can be reduced, thereby achieving the purpose of power saving for the terminal.

[0172] Therefore, in an embodiment of the present application, the network device indicates the resource information of the reference signal and / or the monitoring timing information of the reference signal to the terminal device in the idle state or deactivated state through the target information carried in the public PDCCH. In other words, the technical solution of the present application uses the public PDCCH to carry the target information, which can avoid configuring a new PDCCH search space for the terminal device in the idle state or deactivated state, reduce system overhead, and have good backward compatibility. In addition, the technical solution of the present application can reduce the monitoring of the public PDCCH carrying the target information, thereby achieving the purpose of terminal power saving.
