Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular, to an information transmission method and a transmission device in the field of communications. Background Art

[0002] The cell discontinuous transmission (DTX) / discontinuous reception (DRX) technology is one of the important technologies for achieving energy saving of network devices and terminal devices. Exemplarily, a network device may instruct a terminal device to activate DTX / DRX. By activating DTX / DRX, the network device and the terminal device can perform data transmission during the DTX on-time / DRX on-time; and do not perform data transmission during the DTX off-time / DRX off-time, thereby achieving energy saving of the network device and the terminal device.

[0003] However, such an information transmission method still results in poor energy saving effects for network devices and terminal devices. Summary of the Invention

[0004] The present application provides an information transmission method and a transmission device, which can improve the energy saving effects of network devices and terminal devices.

[0005] In a first aspect, an information transmission method is provided. The method includes: receiving first information, where the first information is used to indicate that a first network device is in an energy-saving state, and the energy-saving state includes that discontinuous transmission (DTX) is in an active state and / or discontinuous reception (DRX) is in an active state; and based on the first information, listening for public information, where the public information includes at least one of the following: system information, synchronization signal block, paging message, or paging early indication.

[0006] In a possible implementation manner, the method is executed by a terminal device or a chip in the terminal device.

[0007] It should be understood that in one case, the first network device may be the network device 1 in the present application, that is, the network device 1 instructs the terminal device that the network device 1 is in an energy-saving state. In another case, the first network device may be the network device 3 in the present application, that is, the network device 2 instructs the terminal device that the network device 3 is in an energy-saving state.

[0008] In the information transmission method of the present application, when the network device is in the energy-saving state, the network device broadcasts public information using a strategy that is more conducive to the energy-saving of the network device, such as broadcasting public information with a larger period, etc., and at the same time indicates to the terminal device that the network device is in the energy-saving state, so that the terminal device can use the corresponding strategy to monitor the public information, making the energy-saving effects of the network device and the terminal device better. At the same time, the terminal device can timely determine the state change of the network device and the change of the strategy for broadcasting public information, so that the terminal device can receive public information according to the correct strategy.

[0009] In combination with the first aspect, in some embodiments of the first aspect, the first information is system information; the method further includes: receiving second information from a first network device, where the second information is used to indicate a change in the system information; receiving the first information includes: in response to the second information, monitoring the system information and receiving the first information.

[0010] It should be understood that the second information may be, for example, a short message, and the change in the system information is indicated by bit 1 in the short message. In response to the second information, the terminal device can re-monitor the system information and determine that the first network device is in the energy-saving state according to the system information.

[0011] In combination with the first aspect, in some embodiments of the first aspect, monitoring the public information includes: monitoring the public information according to a first configuration; where the first configuration includes one or more of the following: a first period; not monitoring the first type of public information in the public information; monitoring the remaining types of public information after receiving the early paging indication; during the DTX on time and / or the DRX on time, monitoring the public information according to a third period; or, during the DTX off time and / or the DRX off time, monitoring the public information according to a fourth period or an irregular time interval. In this way, the first network device broadcasts public information according to the strategy corresponding to the first configuration, and the terminal device can use the strategy corresponding to the first configuration to monitor the public information, making the energy-saving effects of the first network device and the terminal device better.

[0012] In combination with the first aspect, in some embodiments of the first aspect, the method further includes: receiving third information from a first network device, where the third information is used to indicate the first configuration. In this way, the first network device can flexibly determine the first configuration and send the first configuration to the terminal device, so that the terminal device can monitor the public information according to the first configuration, which helps the energy-saving of the first network device and the terminal device.

[0013] In combination with the first aspect, in some embodiments of the first aspect, the first period is determined by a second period and N, the second period is the period for monitoring the public information when the DTX is in the deactivated state and / or the DRX is in the deactivated state, the first period is N times the second period, and N is a positive number.

[0014] It should be understood that N can also be understood as a scaling factor for the second period. N can be, for example, 2, 3, or 4, etc. In this way, the first network device can indicate N to the terminal device, so that the terminal device can determine the first period according to N and the second period, which helps to reduce signaling overhead.

[0015] Combined with the first aspect, in some embodiments of the first aspect, the method further includes: receiving fourth information from the first network device, where the fourth information is used to indicate configuration parameters of DTX and / or DRX, and the configuration parameters include at least one of the following: DTX period and / or DRX period, duration of DTX on-time and / or DRX on-time, or start time interval of DTX and / or start time interval of DRX. In this way, the terminal device can determine the DTX on-time and / or DRX on-time, as well as the DTX off-time and / or DRX off-time. Thus, it is convenient for the terminal device to monitor public information using a certain strategy during the DTX on-time and / or DRX on-time; and monitor public information using other strategies during the DTX off-time and / or DRX off-time.

[0016] Combined with the first aspect, in some embodiments of the first aspect, the method further includes: based on the first information, sending fifth information to the first network device, where the fifth information is used to request random access.

[0017] It should be understood that the fifth information can be, for example, a random access request, a random access signal, etc. When the terminal device determines that the first network device is in an energy-saving state, for example, the DRX of the first network device is in an active state, etc., the terminal device can use a corresponding strategy to send the fifth information, which helps to improve the energy-saving effect of the terminal device and the first network device. For example, the terminal device can send the fifth information during the DRX on-time, etc.

[0018] Combined with the first aspect, in some embodiments of the first aspect, sending the fifth information to the first network device includes: sending the fifth information to the first network device according to a second configuration; where the second configuration includes one or more of the following: sending the fifth information during the DTX on-time and / or DRX on-time; or, sending the fifth information after receiving the second type of public information; or, sending the fifth information on a first time-frequency resource; or, during the DTX off-time and / or DRX off-time, sending the fifth information on a second time-frequency resource; or, during the DTX off-time and / or DRX off-time, sending the fifth information after receiving the second type of public information. In this way, the terminal device can send the fifth information according to the second configuration. This helps to improve the success rate of the terminal device accessing the first network device, and also helps to improve the energy-saving effect of the first network device and the terminal device.

[0019] Optionally, the second configuration may be configured by signaling or agreed upon by protocol by the first network device.

Wherein, time period 1 belongs to a part of the DRX off time and / or time period 1 belongs to a part of the DTX off time. Time period 1 may be a period of time after starting to enter the DRX off time and / or starting to enter the DTX off time, for example, within 2 time slots after starting to enter the DRX off time. Alternatively, time period 1 may be a time period after a period of time from the moment of entering the DRX off time and / or a time period after a period of time from the moment of entering the DTX off time, for example, a time period 2 time slots after the moment of entering the DRX off time.

[0021] Optionally, time period 1 may be agreed upon by protocol or configured by signaling by the first network device.

The above network device can also be an urban base station, a micro base station, a pico base station, a femto base station, etc. This application does not make any limitations in this regard.

[0075] First, some technical terms involved in this application are introduced.

[0076] 1. A synchronization signal / PBCH block (SSB) is the basis for cell search. The synchronization signal includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Together, the PSS / SSS and the physical broadcast channel (PBCH) are called the synchronization signal block SSB. Among them, the master information block (MIB) is transmitted on the PBCH, and the terminal device obtains the system information block (SIB) information by reading the MIB information.

[0077] Among them, the MIB is used to carry the scheduling information of the system information block, etc.

[0078] 2. System messages include various information that the network device uses to notify the terminal device about the system. For example, network information of the cell where the terminal device is located, information of the registered area, information of public channels, and information of other cells, etc., which are system-related information. System messages include SIB1 and other system information blocks (OSI).

[0079] SIB1 is used to carry cell selection information, access control information, channel configuration information related to initial access, and scheduling information of the remaining system information blocks, while the system information blocks contain specific data. System messages are carried on a set of radio frames and can be broadcast by the broadcast channel (BCH). The BCH is a unidirectional control channel that can broadcast the common information of the cell and consists of the frequency correction channel (FCCH), the synchronization channel (SCH), and the broadcast control channel (BCCH).

[0080] 3. Paging messages can include paging messages of the short message type and paging messages of the paging terminal type.

[0081] Among them, the paging messages of the short message type can, for example, indicate system information update, earthquake and tsunami warning, etc. For the paging messages of the short message type, terminal devices in the radio resource control (RRC) idle state, inactive state, and RRC connected state all need to receive them. The paging messages of the paging terminal type can include multiple paging UE IDs. When the terminal device determines that there is a paging UE ID in the multiple paging UE IDs in the paging message that is the same as its own paging UE ID, it can determine that the network device has paged the terminal device, and then can access the network device through processes such as random access. For the paging messages of the paging terminal type, terminal devices in the RRC idle state and RRC inactive state need to receive them, while terminal devices in the RRC connected state do not need to receive them.

[0082] 4. The paging messages of the short message type can also be called short messages. They can include 8 bits, and each bit can be used to indicate different information. For example, bit 1 indicates whether the system information has changed (for example, if bit 1 is 1, it indicates that the system information has changed); bit 2 indicates earthquake and typhoon alarm notifications (for example, if bit 2 is 1, it indicates an earthquake and typhoon alarm); bit 3 indicates whether paging monitoring has stopped (for example, if bit 3 is 1, it indicates to stop monitoring the PDCCH paging in this paging occasion, etc.). The other bits can be reserved.

[0083] 5. Paging early indication (PEI) is used to indicate the information for the terminal device to monitor paging messages.

[0084] It should be understood that if the PEI indicates that a paging message needs to be received during a paging occasion, the terminal device needs to receive the paging message during the corresponding paging occasion; if the PEI indicates that there is no need to monitor the paging message during the paging occasion, the terminal device does not need to monitor the paging message during the paging occasion.

[0085] 6. Discontinuous transmission (DTX) / discontinuous reception (DRX) is a network energy-saving technology.

[0086] The network device can activate or deactivate DTX / DRX, that is, DTX / DRX can be in an active state or a deactivated state. That DTX / DRX can be in an active state may mean that the network device and the terminal device communicate using the DTX / DRX technology. Correspondingly, that DTX / DRX is in a deactivated state may mean that the network device and the terminal device do not communicate using the DTX / DRX technology.

[0087] When DTX / DRX can be in an active state, the network device and the terminal device can perform data transmission during the DTX on time / DRX on time; no data transmission is performed during the DTX off time / DRX off time.

[0088] Exemplarily, Figure 1 is a schematic diagram of a case where DTX is in an active state (or DRX is in an active state). When DTX is activated, the DTX on time (or DRX on time) can be as shown by the raised part in Figure 1 , and the DTX off time (or DRX off time) can be as shown by the sunken part in Figure 1 . The DTX cycle (or DRX cycle) may refer to the time interval between two adjacent moments when starting to enter the DTX on time (or DRX on time), or the DTX cycle (or DRX cycle) may refer to the time interval between two adjacent moments when starting to enter the DTX off time (or DRX off time).

[0089] During the DTX activation time, the network device can send downlink information. Correspondingly, the terminal device can listen for / receive the downlink information from the network device. During the DTX deactivation time, the network device does not send downlink data, and the terminal device can stop listening for the downlink information from the network device. Similarly, in the case of activating DRX, during the DRX activation time, the terminal device can send uplink information to the network device. Correspondingly, the network device can listen for / receive the uplink data from the terminal device. During the DRX deactivation time, the terminal device does not send uplink information to the network device. Correspondingly, the network device does not listen for / does not receive the uplink data sent by the terminal device. In this way, during the DRX deactivation time and / or the DTX deactivation time, the power consumption of the network device and the terminal device is relatively low. Therefore, when DTX / DRX is in the active state, it can be considered that the network device is in the energy-saving state.

[0090] It should be understood that in the embodiments of the present application, the active state and the deactivated state are examples used to describe whether the DTX / DRX technology is in use. The active state can also be referred to as the enabled state, and the deactivated state can also be referred to as the disabled state. Correspondingly, activating DTX / DRX can also be referred to as enabling DTX / DRX, and deactivating DTX / DRX can also be referred to as disabling DTX / DRX. In addition, the DTX activation time / DRX activation time can also be referred to as the DTX active time / DRX active time, and the DTX deactivation time / DRX deactivation time can also be referred to as the DTX deactive time / DRX deactive time. The present application does not make specific limitations in this regard.

[0091] For ease of understanding the embodiments of the present application, first, in combination with Figure 2 and Figure 3 a communication system applicable to the embodiments of the present application will be described in detail.

[0092] Figure 2 FIG. 200 is a schematic diagram of a communication system 200 applied in the embodiments of the present application. The communication system 200 may include at least one network device, such as Figure 2 the network device 210 shown in FIG. 202; the communication system 200 may further include at least one terminal device, such as Figure 2 the terminal device 220 shown in FIG. 203. The network device 210 and the terminal device 220 can communicate via a wireless link. In one possible case, the network device 210 can be used as the sender, and the terminal device 220 can be used as the receiver, and the network device 210 sends a signal to the terminal device 220. In another possible case, the network device 210 can be used as the receiver, and the terminal device 220 can be used as the sender, and the terminal device 220 sends a signal to the network device 210.

[0093] Figure 2Exemplarily, a network device 210 and a terminal device 220 are shown. Optionally, the communication system 200 may further include multiple network devices and / or multiple terminal devices. The network device 210 may be a router, a base station, etc., and the terminal device 220 may be a mobile phone, a tablet computer, a smart bracelet, etc. The embodiments of the present application do not limit this.

[0094] Each of the above communication devices, such as Figure 2 the network device 210 or the terminal device 220 in

[0095] may be configured with multiple antennas. The multiple antennas may include at least one transmit antenna for transmitting signals and at least one receive antenna for receiving signals. Additionally, each communication device further includes a transmitter chain and a receiver chain, and those of ordinary skill in the art can understand that they may both include multiple components related to signal transmission and reception (such as a processor, a modulator, a multiplexer, a demodulator, a demultiplexer, or an antenna, etc.). Therefore, communication between the network device 210 and the terminal device 220 can be achieved through multi-antenna technology.

[0096] It should also be understood that the method provided by the embodiments of the present application can be applied to various communication systems including 5G new radio (NR) systems. The communication system 200 is only an example, and the present application does not limit the specific architecture of the applicable system, nor does it limit the quantity and form of various devices included in each communication system.

[0097] Currently, when DTX / DRX is in the active state, whether it is during the DTX on-time / DRX on-time, or during the DRX off-time and / or DTX off-time, the network device broadcasts public information, such as system information, paging messages, etc., using the same period. Correspondingly, the terminal device also needs to listen for the public information broadcast by the network device using the same period. Such an information transmission method results in poor energy-saving effects for both the network device and the terminal device.

[0098] To solve the above technical problems, the present application provides an information transmission method. When DTX / DRX is in the active state, the network device can adopt a certain strategy to broadcast public information, such as using a period larger than the period for broadcasting public information when DTX / DRX is in the deactivated state, etc., thereby achieving better energy-saving effects for the network device. Moreover, when DTX / DRX is in the active state, the network device can indicate to the terminal device that the network device is in the energy-saving state, enabling the terminal device to also listen for public information according to the corresponding strategy. In this way, the number of times the terminal device listens for public information can be reduced, resulting in better energy-saving effects for the terminal device.

[0099] The following will combine with Figures 3 to 5 to introduce the information transmission method of this application in detail. The embodiments shown in this application show the information transmission method provided by this application from the perspective of device interaction. The specific forms and quantities of the various devices shown are only examples and should not constitute any limitation to the implementation of the method provided by this application. Below, taking the terminal device and the network device as the execution entities as an example, the information transmission method of the embodiments of this application will be described in detail.

[0100] It should be understood that the terminal device can be the terminal device itself, can be a chip, a chip system or a processor that supports the terminal device to implement the data transmission method, or can also be a logic module or software that can implement all or part of the terminal device; the network device can be the network device itself, can be a chip, a chip system or a processor that supports the network device to implement the data transmission method, or can also be a logic module or software that can implement all or part of the network device. This application does not make specific limitations on this.

[0101] Figure 3 It is a schematic flowchart of an information transmission method 300 provided by an embodiment of this application. The method 300 can be applied to a system including a terminal device and a network device, such as the system 200. The network device can be, for example, Figure 3 the network device 1 shown. The terminal device can be an idle or inactive terminal device.

[0102] The method 300 includes the following steps:

[0103] S301. The network device 1 sends the first information. Correspondingly, the terminal device receives the first information. The first information is used to indicate that the network device 1 is in an energy-saving state, and the energy-saving state includes that DTX is in an active state and / or DRX is in an active state.

[0104] Among them, the network device 1 can indicate that the network device 1 is in an energy-saving state in various ways. Exemplarily, the first information can include a preset identifier, such as 1 or on, etc., and 1 or on can be used to indicate that the network device 1 is in an energy-saving state; or, the first information corresponding to the message itself is used to indicate that the network device 1 is in an energy-saving state, etc. This application does not make specific limitations on the specific form of the first information.

[0105] It should be noted that both the active state of DTX and / or the active state of DRX belong to the energy-saving state. The embodiments of this application can be applicable to the situation where DTX of the network device 1 is in an active state and / or DRX of the network device 1 is in an active state. This application does not make specific limitations on this.

[0106] Optionally, the first information may be carried in a short message. For example, bit 4, bit 5, or bit 6 in the short message, etc. Assume that the fourth information is bit 4 in the short message. When bit 4 in the short message is 1 or 0, it may indicate that network device 1 is in an energy-saving state.

[0107] S302. Network device 1 sends public information. Correspondingly, the terminal device listens for and receives the public information. The public information includes at least one of the following: system information, synchronization signal block, paging message, or paging early indication.

[0108] It should be understood that the random access time-frequency resource information may be information used to indicate the random access time-frequency resource, and the random access pilot information may be information used to indicate the random access pilot. The random access time-frequency resource information and the random access pilot may be sent in one signaling or in different signallings. The strategy adopted by network device 1 to send public information may be different from the strategy adopted when DTX is in the deactivated state and / or DRX is in the deactivated state. Moreover, compared with the strategy adopted by network device 1 to send public information when DTX is in the deactivated state and / or DRX is in the deactivated state, the strategy adopted by network device 1 to send public information when DTX is in the activated state and / or DRX is in the activated state is a strategy that makes network device 1 more energy-efficient.

[0109] It should be noted that if DTX of network device 1 is in the activated state, the strategy adopted by network device 1 to send public information subsequently may be related to the configuration parameters of DTX; if DRX of network device 1 is in the activated state, the strategy adopted by network device 1 to send public information subsequently may be related to the configuration parameters of DRX; if DRX of network device 1 is in the activated state and DTX is in the activated state, the strategy adopted by network device 1 to send public information subsequently may be related to the configuration parameters of DRX and / or the configuration parameters of DTX. This application does not make specific limitations in this regard.

[0110] It should also be noted that in the embodiments of this application, the public information includes but is not limited to the following information: system information, synchronization signal block, paging message, or paging early indication. For example, the public information may also be other information sent through the physical downlink control channel (PDCCH). This application does not make specific limitations in this regard.

[0111] In the information transmission method of this application, when the network device is in the energy-saving state, the network device broadcasts public information using a strategy that is more conducive to the energy saving of the network device, such as broadcasting public information with a longer period, etc. At the same time, it indicates to the terminal device that the network device is in the energy-saving state, so that the terminal device can use the corresponding strategy to listen for public information, making the energy-saving effects of the network device and the terminal device better. At the same time, the terminal device can timely determine the state change of the network device and the change in the strategy of broadcasting public information, so that the terminal device can receive public information according to the correct strategy.

[0112] As an optional embodiment, if the first information is system information, method 300 further includes: the network device 1 sends second information to the terminal device, and the second information is used to indicate a change in the system information; S301 can be implemented in the following manner: in response to the second information, the network device 1 sends the first information.

[0113] It should be understood that the second information can be, for example, a short message, and the change in the system information is indicated by bit 1 in the short message. In response to the second information, the terminal device can re-listen for the system information and determine that the network device 1 is in the energy-saving state according to the system information.

[0114] It should be understood that in addition to the system information, the first information can also be carried in a downlink message sent through the PDCCH, and this application does not make specific limitations in this regard.

[0115] Next, the strategy for the network device 1 to send public information and the strategy for the terminal device to listen for public information when the network device 1 is in the energy-saving state will be described. This strategy can be divided into two cases. In one case, this strategy can be implemented without relying on the configuration parameters of DTX and / or the configuration parameters of DRX, such as the following first configurations 1 to 7; in another case, this strategy is implemented based on the configuration parameters of DTX and / or the configuration parameters of DRX, such as the following first configurations 8 to 10.

[0116] As an optional embodiment, S302 can be implemented in the following manner: the network device 1 sends public information using a first configuration. Correspondingly, the terminal device listens for and receives public information using the first configuration. The first configuration includes one or more of the following: a first period; not sending the first type of public information in the public information; sending the remaining types of public information after sending the paging early indication; within the DTX on time and / or the DRX on time, the network device 1 sends public information according to a third period, and correspondingly, the terminal device listens for public information according to the third period; or, within the DTX off time and / or the DRX off time, the network device 1 sends public information according to a fourth period or an irregular time interval, and correspondingly, the terminal device listens for public information according to the fourth period or an irregular time interval.

[0117] Among them, the first configuration can be understood as the policy for the network device 1 to send public information or the policy for the terminal device to listen for public information.

[0118] The first type is that the first configuration is the first period.

[0119] Among them, the first period is a positive number. The first period can be greater than the period used for the network device 1 to broadcast public information when it is in a non-energy-saving state. For example, if the period used for the network device 1 to broadcast public information when it is in a non-energy-saving state is 10 ms, then the first period can be 15 ms, 30 ms, etc.

[0120] In this way, the network device 1 can broadcast public information with a larger period, and the terminal device can listen for public information with a larger period, making the energy-saving effect of the network device 1 and the terminal device better.

[0121] The second type is that the first configuration is not to send the first type of public information in the public information. The first type of public information can be one or more of the public information. For example, it can be system information, synchronization signal block, paging message, or random access message, etc. The random access message can include random access time-frequency domain resource information and / or random access pilot information. Correspondingly, for the terminal device, the first configuration is not to listen for the first type of public information in the public information.

[0122] In this way, the network device 1 can not send the first type of public information, and the terminal device can not listen for the first type of public information, making the energy-saving effect of the network device 1 and the terminal device better.

[0123] The third type is to send the remaining types of public information after sending the paging early indication. The remaining types of public information are the information in the public information except the paging early indication. For example, paging message, system information, etc. Correspondingly, for the terminal device, the first configuration is to listen for the remaining types of public information after listening for the paging early indication.

[0124] In this way, before the terminal device listens for the paging early indication, it can not listen for the remaining types of public information. After receiving the paging early indication, it listens for the remaining types of public information, making the energy-saving effect of the terminal device better.

[0125] Optionally, information for indicating listening for other types of common information may be carried in the early paging indication. Exemplarily, information for indicating listening for paging messages or common information is carried in the early paging indication. For example, in the early paging indication, information for indicating listening for paging messages or common information is indicated by bit information. When the bit information is 11, it may indicate listening for common information; when the bit information is 00, it may indicate listening for paging messages; when the bit information is 10, it may indicate listening for both common information and paging messages, etc.

[0126] In this way, before the terminal device listens to the early paging indication, it may not listen to other types of common information. After receiving the early paging indication, it may listen to other types of common information according to the information for indicating listening for other types of common information carried in the early paging indication, so that the energy saving effect of the terminal device is better.

[0127] Optionally, the network device 1 sends information for indicating other types of common information to the terminal device. The information for indicating other types of common information may be, for example, bit information. When the bit information is 11, it may indicate listening for common information; when the bit information is 00, it may indicate listening for paging messages; when the bit information is 10, it may indicate listening for both common information and paging messages, etc.

[0128] It should be understood that the information for indicating other types of common information and the early paging indication may be sent through the same signaling or different signaling, and the present application does not make specific limitations in this regard.

[0129] It should be noted that in some possible implementation manners, the early paging indication may also be replaced with a newly defined listening indication information, that is, a signaling different from the early paging indication. For example, the newly defined listening indication information may be a downlink message sent through the PDCCH. The present application does not make specific limitations on the content or format included in this listening indication information.

[0130] The fourth type, the first configuration is the first period and does not send the first type of common information among the common information. That is, while the network device 1 does not send the first type of common information, it sends other types of common information in the first period.

[0131] In this way, the network device 1 can broadcast common information in a larger period, the terminal device can listen to common information in a larger period, and the network device 1 can not send the first type of common information, and the terminal device can not listen to the first type of common information, so that the energy saving effects of the network device 1 and the terminal device are better.

[0132] The fifth type, the first configuration is that the first cycle is for the first paging early indication and then the remaining types of common information are sent. That is, the terminal device listens for the remaining types of common information after listening for the paging early indication. And the network device 1 sends the paging early indication and / or the remaining types of common information in the first cycle, and the terminal device listens for the paging early indication and / or the remaining types of common information in the first cycle.

[0133] In this way, the network device 1 can broadcast the common information in a larger cycle, the terminal device can listen for the common information in a larger cycle, and before the terminal device listens for the paging early indication, it can not listen for the remaining types of common information, making the energy-saving effect of the network device 1 and the terminal device better.

[0134] The sixth type, the first configuration is not to send the first type of common information in the common information and then send the remaining types of common information after sending the paging early indication.

[0135] In this way, the network device 1 can not send the first type of common information, the terminal device can not listen for the first type of common information, and before the terminal device listens for the paging early indication, it can not listen for the remaining types of common information, making the energy-saving effect of the network device 1 and the terminal device better.

[0136] The seventh type, the first configuration is the first cycle, not sending the first type of common information in the common information, and then sending the remaining types of common information after sending the paging early indication.

[0137] In this way, the network device 1 can broadcast the common information in a larger cycle, the terminal device can listen for the common information in a larger cycle; the network device 1 can not send the first type of common information, the terminal device can not listen for the first type of common information; and before the terminal device listens for the paging early indication, it can not listen for the remaining types of common information, making the energy-saving effect of the network device 1 and the terminal device better.

[0138] The eighth type, the first configuration is that within the DTX on time and / or the DRX on time, the network device 1 sends the common information according to the third cycle. Correspondingly, the terminal device listens for the common information according to the third cycle; and / or, within the DTX off time and / or the DRX off time, the network device 1 sends the common information according to the fourth cycle or an irregular time interval. Correspondingly, the terminal device listens for the common information according to the fourth cycle or an irregular time interval.

[0139] The third period can be the same as the second period, that is, the third period is the period for listening to public information when DTX is in the deactivated state and / or DRX is in the deactivated state. The third period can also be different from the second period. The fourth period can be different from the third period, and the fourth period can be greater than the third period. For example, the third period is 10 ms and the fourth period is 30 ms. Alternatively, the fourth period can be M times the third period, where M is a positive integer. Exemplarily, as Figure 4 shown, when M is 2, the moments when the network device 1 sends public information or the terminal device listens to public information can be Figure 4 the moments indicated by the solid arrows in. At the moments indicated by the dashed arrows, the network device 1 does not send public information, and the terminal device does not listen to public information.

[0140] The irregular time interval can be understood as that within a period of DTX off time (or DRX off time), the multiple time intervals during which the network device 1 sends public information are not exactly the same, that is, the multiple time intervals during which the terminal device listens to public information are not exactly the same. Each of the multiple time intervals is the time interval between two adjacent moments when the network device 1 sends public information.

[0141] In the first example, within a period of DTX off time (or DRX off time), the second time interval during which the network device 1 sends public information is 2 times the first time interval during which it sends public information, the third time interval during which it sends public information is 3 times the first time interval during which it sends public information, the fourth time interval during which it sends public information is 4 times the first time interval during which it sends public information, and so on. The first time interval during which the network device 1 sends public information can be understood as the time interval between the first moment and the second moment when the network device 1 sends public information after entering this period of DTX off time (or DRX off time). The second time interval during which the network device 1 sends public information is the time interval adjacent to the first time interval, that is, the time interval between the second moment and the third moment when the network device 1 sends public information, and so on.

[0142] In the second example, within a period of DTX off time (or DRX off time), the second time interval during which the network device 1 sends public information is 1 / 2 of the first time interval during which it sends public information, the third time interval during which it sends public information is 1 / 3 times the first time interval during which it sends public information, the fourth time interval during which it sends public information is 1 / 4 times the first time interval during which it sends public information, and so on. Among them, the explanations of the first time interval, the second time interval, the third time interval, and the fourth time interval are the same as those in the first example. Please refer to the above description and will not be elaborated here.

[0143] In the above two examples, the first time interval may be the same as or different from the second period. The first time interval may be agreed upon by the protocol or indicated by the network device 1 through signaling.

[0144] In the 9th case, the first configuration is that within the DTX on time and / or the DRX on time, the network device 1 sends common information according to the third period, and correspondingly, the terminal device listens for the common information according to the third period; and / or, within the DTX off time and / or the DRX off time, the network device 1 does not send the first type of common information in the common information and / or sends the remaining types of common information after sending the paging early indication, and correspondingly, the terminal device does not listen for the first type of common information in the common information and / or listens for the remaining types of common information after listening for the paging early indication.

[0145] It should be understood that the third period may be the same as or different from the second period. The indication method of not sending the first type of common information in the common information and / or sending the remaining types of common information after sending the paging early indication may refer to the description above and will not be elaborated here.

[0146] In the 10th case, the first configuration is that within the DTX on time and / or the DRX on time, the network device 1 does not send the first type of common information in the common information, and correspondingly, the terminal device does not listen for the first type of common information in the common information; and / or, within the DTX off time and / or the DRX off time, the network device 1 sends the remaining types of common information after sending the paging early indication, and correspondingly, the terminal device listens for the remaining types of common information after listening for the paging early indication.

[0147] It should be understood that in this embodiment, the policy of the network device 1 sending common information within the DTX on time and / or the DRX on time and the policy of the network device 1 sending common information within the DTX off time and / or the DRX off time may also be interchanged. For the sake of simplicity of description, it will not be elaborated here.

[0148] It should be noted that the several policies included in the first configuration may also be arranged and combined in a manner different from the above 10 ways. No matter which combination of the above several policies the first configuration is, its implementation manner is similar to the above 10 implementation manners and may refer to the description above. They will not be listed one by one here.

[0149] Based on the above embodiments, the first configuration may be agreed upon by the protocol or configured by the network device 1 through signaling.

[0150] In the first possible implementation manner, the first configuration is configured by the network device 1 through signaling: The method 300 further includes: The network device 1 sends the third information to the terminal device, and the third information is used to indicate the first configuration.

[0151] It should be understood that the third information and the first information (or) can be sent through one signaling, or can be sent through different signalings. In the case where the third information and the first information are sent through one signaling, the third information and the first information can be carried in the same or different cells of the signaling, or the third information and the first information can be carried in the same or different fields of the signaling. This application does not make specific limitations on this.

[0152] In this way, the network device 1 can flexibly determine the first configuration and send the first configuration to the terminal device, so that the terminal device can monitor the public information according to the first configuration, which helps to save energy for the network device 1 and the terminal device.

[0153] Optionally, the third information and / or the first information can be carried in the system information. Or, the third information can also be carried in the RRC release (RRC release) message. The third information can be configured when the network device 1 releases the terminal device to the RRC idle state or the RRC inactive state.

[0154] Among them, the first period can be indicated in one of the following ways:

[0155] 1. The third information directly indicates the first period. For example, the third information includes 20, and 20 indicates that the first period is 20 ms.

[0156] 2. The third information includes a first preset identifier, and this first preset identifier represents the first period. The preset identifier can be, for example, 0, 2, A1, or 1100, etc. 0, 2, A1, or 1100 indicates that the first period is 20 ms.

[0157] 3. The third information includes information for indicating N, or the third information includes information for indicating N and the second period. The second period is the period for monitoring public information when DTX is in the deactivated state and / or DRX is in the deactivated state, and the first period is N times the second period, where N is a positive number.

[0158] It should be understood that N can also be understood as the scaling factor of the second period. N can be, for example, 2, 3, or 4, etc.

[0159] In this way, the terminal device can determine the first period according to the second period and N.

[0160] When the third information includes N, the terminal device may know the second period. For example, the second period is agreed upon by the protocol, or the terminal device uses the second period to monitor public information before receiving the first information. In this way, the network device 1 does not need to indicate the second period, and the signaling overhead is small. When the third information includes N and the second period, the terminal device may determine the first period through the following formula: the first period = N × the second period.

[0161] Among them, the information used to indicate N may be N itself, or may also be a second preset identifier. The second preset identifier may be, for example, 10, 01, 00, etc. 10 may indicate that N is 2, 01 may indicate that N is 4, 00 may indicate that N is 6, etc.

[0162] It should be noted that the number of the first periods may be multiple. For example, the first period may include the period of system information, the period of synchronization information block, the period of paging message, etc. Correspondingly, the number of N may also be multiple. For example, N includes the period scaling factor corresponding to system information, the scaling factor of the period of paging message, etc. The present application does not make specific limitations on this.

[0163] In an example, the first information is system information. Different from the system information sent by the network device 1 when DTX is in the inactive state and DRX is in the inactive state, the first period is additionally configured in the first information. The first period includes: the transmission period of the synchronization information block: for example, ssb - periodicity serving cell - nes ms40; the transmission period of the paging message: for example, paging cycle - nes rf64; the transmission period of the system information, for example, si - periodicity - nes rf64. Among them, ssb - periodicity serving cell - nes ms40 indicates that the transmission period of the synchronization information block additionally configured in this system information is 40 ms; paging cycle - nes rf64 indicates that the transmission period of the paging message additionally configured in this system information is 64 radio frames (rf); si - periodicity - nes rf64 indicates that the transmission period of the system information additionally configured in this system information is 64 rf.

[0164] In another example, the first information is system information, which is different from the system information sent by network device 1 when DTX is in the inactive state and DRX is in the inactive state. Additionally, N is configured in the first information. For example, the system information sent by network device 1 when DTX is in the inactive state and DRX is in the inactive state includes the transmission period of the synchronization information block: for example, ssb - periodicity serving cell ms10; and the transmission period of the paging message: for example, paging cycle rf32. Then, the first information includes the transmission period of the synchronization information block and the transmission period of the paging message, and also includes the scaling factor 4 of the transmission period of the synchronization information block and 2 of the transmission period of the paging message. 4 and 2 can be understood as the above - mentioned N.

[0165] Optionally, method 300 further includes: network device 1 sends information for indicating the first period to the terminal device. Correspondingly, the terminal device receives the information for indicating the first period from network device 1. The manner in which the information for indicating the first period indicates the first period can refer to the manner in which the third information indicates the first period, which will not be elaborated here.

[0166] It should be understood that the information for indicating the first period and the third information may be sent through the same signaling or different signaling. And in the case where the information for indicating the first period and the third information are sent through the same signaling, the information for indicating the first period and the third information may be carried in the same or different fields, or the information for indicating the first period and the third information may be carried in the same or different cells. This application does not make specific limitations on this.

[0167] Not sending the first type of common information in the common information and / or sending the remaining types of common information after sending the paging early indication can be indicated by one or several of the following methods:

[0168] The third information includes information for indicating the first type of common information, such as #SSB or 0011. #SSB can represent the synchronization information block, and the terminal device can determine that network device 1 does not send the synchronization information block according to #SSB; 0011 can represent the system information, and the terminal device can determine that network device 1 does not send the system information according to 0011.

[0169] The third information includes a third preset identifier, and the third preset identifier is used to indicate not sending the first type of common information in the common information and / or sending the remaining types of common information after sending the paging early indication. The third preset identifier can be, for example, 0, 1100, etc. For example, 1100 can represent not sending the system information.

[0170] Optionally, method 300 further includes: The network device 1 sends information for indicating the first type of common information to the terminal device. Correspondingly, the terminal device receives the information for indicating the first type of common information from the network device 1. The manner in which the information for indicating the first type of common information indicates the first type of common information may refer to the manner in which the third information indicates the first type of common information, which will not be elaborated here.

[0171] It should be understood that the information for indicating the first type of common information and the third information may be sent through the same signaling or different signaling. And in the case where the information for indicating the first type of common information and the third information are sent through the same signaling, the information for indicating the first type of common information and the third information may be carried in the same or different fields, or, the information for indicating the first type of common information and the third information may be carried in the same or different cells. The present application does not make specific limitations on this. In addition, the third period, and / or, the fourth period or the irregular time interval may be indicated in the following manner.

[0172] In a possible implementation manner, the third period, and / or, the fourth period or the irregular time interval is indicated by the network device 1 through signaling. Method 300 further includes: The network device 1 sends information for indicating the third period, and / or, the fourth period or the irregular time interval to the terminal device. Correspondingly, the terminal device receives the information for indicating the third period, and / or, the fourth period or the irregular time interval from the network device 1.

[0173] It should be understood that when the third period is the same as the second period, the third period may be a period known to the terminal device. The network device 1 may indicate the fourth period or the irregular time interval to the terminal device. When the third period is different from the second period, the network device 1 may indicate the third period, and, the fourth period or the irregular time interval to the terminal device.

[0174] Among them, the information for indicating the third period may be the third period itself, such as 10, etc., and 10 indicates that the third period is 10 ms; the information for indicating the third period may also be the fourth preset identifier, such as 001, etc., and 001 indicates that the third period is 10 ms. The indication manner of the fourth period is similar to that of the third period, which will not be elaborated here. The information for indicating the irregular time interval may be the fifth preset identifier, such as #1, etc., and #1 indicates that the irregular time interval is the time interval described in the first example above.

[0175] Optionally, the information for indicating the third period may be carried in the first field, and the information for indicating the fourth period or the irregular time interval may be carried in the second field. In this way, the terminal device may determine the third period and the fourth period (or the third period and the irregular time interval) according to the field carrying the information.

[0176] It should be understood that the third information and the information used to indicate the third period, and / or the fourth period or the irregular time interval may be sent through one signaling or through different signalings. When the third information and the information used to indicate the third period, and / or the fourth period or the irregular time interval are sent through one signaling, the third information and the information used to indicate the third period, and / or the fourth period or the irregular time interval may be carried in the same or different cells of the signaling, or the third information and the information used to indicate the third period, and / or the fourth period or the irregular time interval may be carried in the same or different fields of the signaling. This application does not make specific limitations on this.

[0177] In another possible implementation manner, the third period, and / or the fourth period or the irregular time interval is agreed upon by the protocol. In this way, after the terminal device determines the DTX start time (or DRX start time) and the DTX stop time (or DRX stop time), it can determine the strategy for listening to the public information according to the third period, and / or the fourth period or the irregular time interval, without the network device 1 indicating the third period, and / or the fourth period or the irregular time interval, and the signaling overhead is relatively small.

[0178] In the second possible implementation manner, the first configuration is agreed upon by the protocol.

[0179] In this way, when the terminal device determines that the network device 1 is in the energy-saving state, it can independently use the first configuration to listen to the public information without the network device 1 indicating the first configuration through signaling, resulting in relatively small signaling overhead.

[0180] Based on the above embodiments, as an optional embodiment, method 300 further includes: the network device 1 sends the fourth information to the terminal device, and the fourth information is used to indicate the configuration parameters of DTX and / or the configuration parameters of DRX, and the configuration parameters include at least one of the following: the DTX period and / or the DRX period, the duration of the DTX start time and / or the duration of the DRX start time, or the starting time interval of DTX and / or the starting time interval of DRX.

[0181] It should be understood that the fourth information and the first information may be sent through one signaling or through different signalings. When the fourth information and the first information are sent through one signaling, the fourth information and the first information may be carried in the same or different cells of the signaling, or the fourth information and the first information may be carried in the same or different fields of the signaling. This application does not make specific limitations on this.

[0182] When DTX is in the active state in the energy-saving state, the fourth information is used to indicate the configuration parameters of DTX, and the terminal device can determine the DTX on-time and DTX off-time according to the configuration parameters of DTX; when DRX is in the active state in the energy-saving state, the fourth information is used to indicate the configuration parameters of DRX, and the terminal device can determine the DRX on-time and DRX off-time according to the configuration parameters of DRX; when DTX is in the active state and DRX is in the active state in the energy-saving state, the fourth information is used to indicate the configuration parameters of DTX and the configuration parameters of DRX, and the terminal device can determine the DTX on-time and DTX off-time according to the configuration parameters of DTX, and determine the DRX on-time and DRX off-time according to the configuration parameters of DRX. The configuration parameters of DTX include at least one of the following: DTX period, duration of DTX on-time, or starting time interval of DTX. The configuration parameters of DRX include at least one of the following: DRX period, duration of DRX on-time, or starting time interval of DRX.

[0183] Among them, the duration of DTX on-time (or DRX on-time) can refer to the duration of a period of DTX on-time (DRX on-time), for example Figure 1 the duration represented by 1 protrusion in

[0184] Optionally, the duration of DTX off-time (or DRX off-time) can be determined by the DTX period (or DRX period) and the duration of DTX on-time (or DRX on-time). For example, the duration of DTX off-time (or DRX off-time) can be the difference between the DTX period (or DRX period) and the duration of DTX on-time (or DRX on-time).

[0185] The starting time interval can also be understood as the starting time or starting moment. The starting time interval can also be understood as the time interval from the starting point of the system frame. For example, if the starting time interval of DRX is 5 time slots, then starting from the moment corresponding to 5 time slots after the starting point of the system frame, the network device 1 activates DRX.

[0186] Based on the configuration parameters of DTX and / or the configuration parameters of DRX, the terminal device can determine the DTX activation time and / or the DRX activation time, as well as the DTX deactivation time and / or the DRX deactivation time. This facilitates the terminal device to monitor common information using a certain strategy during the DTX activation time and / or the DRX activation time; and use other strategies to monitor common information during the DTX deactivation time and / or the DRX deactivation time, without affecting the normal monitoring of the common information sent by network device 1 by the terminal device. For example, network device 1 can send common information according to the 8th to 10th first configurations described above; correspondingly, after the terminal device determines the DTX activation time and / or the DRX activation time, and the DTX deactivation time and / or the DRX deactivation time, it can monitor the common information from network device 1 according to the 8th to 10th first configurations described above. In this way, the terminal device can

[0187] As an optional embodiment, method 300 further includes: sending sixth information to network device 1, where the sixth information is used to trigger network device 1 to broadcast at least one type of common information; network device 1 receives the sixth information from the terminal device, and in response to the sixth information, sends at least one type of common information; the terminal device receives the at least one type of common information.

[0188] Among them, the at least one type of common information can be, for example, a paging message, system information, etc. The sixth information may include information for indicating the at least one type of common information, such as 100, etc., and 100 represents system information. In this way, network device 1 can determine to broadcast the at least one type of common information according to the information for indicating the at least one type of common information.

[0189] In a possible implementation manner, the sixth information is sent during a first time period.

[0190] Among them, the first time period can be determined in the following ways: the start moment and the duration of the first time period, or the start moment and the end moment of the first time period, etc.

[0191] Optionally, the first time period can be agreed upon by the protocol or indicated by network device 1 through signaling.

[0192] For example, network device 1 can send information for indicating the first time period to the terminal device. Correspondingly, the terminal device receives the information for indicating the first time period from network device 1.

[0193] Among them, the information for indicating the first time period can be, for example, 001 and 002, where 001 represents the start moment of the first time period and 002 represents the end moment of the first time period.

[0194] Optionally, the first time period may be a time period belonging to the DTX off time and / or the DRX off time. For example, the first time period is 3 consecutive orthogonal frequency division multiplexing (OFDM) symbols after entering the DTX off time. That is, the terminal device may send the sixth information on 3 OFDM symbols in each DTX off time period. Correspondingly, the information for indicating the first time period may be the information of the 3 OFDM symbols for indication, such as #3, etc.

[0195] In addition to the network device 1 sending the common information according to the first configuration, correspondingly, the terminal device listening for the common information according to the first configuration, the terminal device may also send the uplink information according to the second configuration when determining that the network device 1 is in the energy-saving state.

[0196] As an optional embodiment, method 300 further includes: S303. Based on the first information, the terminal device sends the fifth information to the network device 1, and the fifth information is used to request random access. Correspondingly, the network device 1 receives the fifth information from the terminal device.

[0197] It should be understood that the fifth information may be, for example, a random access request, a random access signal, etc. The fifth information may be used to randomly access the network device 1. When the terminal device determines that the first network device is in the energy-saving state, for example, the DRX of the first network device is in the active state, etc., the terminal device may adopt the corresponding strategy to send the fifth information, which helps to improve the energy-saving effect of the terminal device and the first network device. For example, the terminal device may send the fifth information during the DRX on time, etc.

[0198] In a possible implementation manner, S303 may be implemented in the following manner: The terminal device sends the fifth information according to the second configuration. The second configuration includes one or more of the following: during the DTX on time and / or the DRX on time, the terminal device sends the fifth information to the network device 1; sending the fifth information after receiving the second type of common information, and the second type of common information may be, for example, a paging early indication, etc.; sending the fifth information on the first time-frequency resource; during the DTX off time and / or the DRX off time, sending the fifth information on the second time-frequency resource; or, during the DTX off time and / or the DRX off time, sending the fifth information after receiving the second type of common information.

[0199] Correspondingly, the network device 1 may receive the fifth information according to the second configuration. The second configuration for the network device 1 to receive the fifth information includes one or more of the following: receiving the fifth information during the DTX on-time and / or DRX on-time; receiving the fifth information after sending the second type of common information, where the second type of common information may be, for example, a paging early indication, etc.; receiving the fifth information on the first time-frequency resource; receiving the fifth information on the second time-frequency resource during the DTX off-time and / or DRX off-time; or, receiving the fifth information after sending the second type of common information during the DTX off-time and / or DRX off-time.

[0200] Among them, the first time-frequency resource and / or the second time-frequency resource may be configured by the network device 1 through signaling, agreed upon by the protocol, or pre-configured. Sending the fifth information on the second time-frequency resource during the DTX off-time and / or DRX off-time can be understood as that if the terminal device sends the fifth information to the network device 1 during the DTX off-time and / or DRX off-time, it needs to use the second time-frequency resource. Sending the fifth information after receiving the second type of common information during the DTX off-time and / or DRX off-time can be understood as that if the terminal device sends the fifth information to the network device 1 during the DTX off-time and / or DRX off-time, it needs to send the fifth information after receiving the second type of common information.

[0201] Exemplarily, the terminal device may send the fifth information to the network device 1 during the DTX on-time and / or DRX on-time; it may also send the fifth information after receiving the second type of common information; it may also send the fifth information during the DTX on-time and / or DRX on-time and after receiving the second type of common information. It may also be arranged and combined according to the remaining strategies in the second configuration, which will not be listed one by one here.

[0202] In this way, it helps to improve the success rate of the terminal device accessing the network device 1, and also helps to improve the energy-saving effects of the network device and the terminal device.

[0203] Among them, the second configuration may be configured by the network device 1 through signaling or agreed upon by the protocol. Specifically as follows.

[0204] Optionally, method 300 further includes: the network device 1 sends information 3 to the terminal device, and the information 3 is used to indicate the second configuration. Correspondingly, the terminal device receives the information 3 from the network device 1. In this way, the network device 1 can indicate the timing for the terminal device to send the fifth information, which helps to improve the success rate of the terminal device accessing the network device 1, and also helps to improve the energy-saving effects of the network device and the terminal device.

[0205] Among them, the second type of public information can be configured by the network device 1 through signaling or agreed upon by protocol. The method for the network device 1 to configure the second type of public information through signaling is similar to the method for configuring the first type of public information, and reference can be made to the above description, which will not be elaborated here.

[0206] Optionally, method 300 further includes: receiving information 1 from the network device 1, where information 1 is used to instruct the terminal device to send uplink information during time period 1 in the DRX off time and / or time period 1 in the DTX off time. Among them, time period 1 belongs to a part of the DRX off time and / or time period 1 belongs to a part of the DTX off time. Time period 1 can be a period of time after starting to enter the DRX off time and / or starting to enter the DTX off time, for example, within 2 time slots after starting to enter the DRX off time. Or, time period 1 can be a period of time after a period of time from the moment of entering the DRX off time and / or a period of time after a period of time from the moment of entering the DTX off time, for example, a period of time 2 time slots after the moment of entering the DRX off time.

[0207] Among them, time period 1 can be understood, for example, as the time domain resource included in the above-mentioned second time-frequency domain resource.

[0208] It should be understood that information 1 and information 3 can be sent through the same signaling or different signaling. In the case where information 1 and information 3 are sent through the same signaling, information 1 and information 3 can be sent through the same field or different fields; information 1 and information 3 can also be sent through the same cell or different cells, and the present application does not make specific limitations on this.

[0209] Optionally, time period 1 can be agreed upon by protocol or configured by the network device 1 through signaling.

[0210] In the above method 300, S302 can also be optional content, that is, when the terminal device determines that the network device 1 is in the energy-saving state, the terminal device sends the fifth information to the network device 1 according to the second configuration. For the sake of concise description, the implementation manner of this embodiment can refer to the above, which will not be elaborated here.

[0211] It should be understood that in method 300, the network device 1 can also be replaced by the first network device, and the present application does not make specific limitations on the name of the network device.

[0212] To facilitate the terminal device to access the cell served by the network device in the energy-saving state, the present application also provides an information transmission method. Specifically as follows.

[0213] Figure 5Schematic flowchart of an information transmission method 500 provided by an embodiment of this application. The method 500 can be applied to a system including a terminal device and multiple network devices, such as the system 200. The system 200 can include two network devices and one terminal device. The two network devices can be, for example, Figure 5 the network device 2 and the network device 3 shown. The terminal device can be an idle or inactive terminal device.

[0214] The method 500 includes the following steps:

[0215] S501. The network device 3 sends an eighth piece of information to the network device 2. The eighth piece of information is used to indicate that the network device 3 is in an energy-saving state, and / or configuration parameters of DTX and / or DRX of the network device 3. The configuration parameters include at least one of the following: DTX period and / or DRX period, duration of DTX turn-on time and / or duration of DRX turn-on time, or start time interval of DTX and / or start time interval of DRX. The energy-saving state includes that DTX is in an active state and / or DRX is in an active state. Correspondingly, the network device 2 receives the eighth piece of information from the network device 3.

[0216] It should be understood that in the case where the network device 3 indicates the configuration parameters of DTX and / or DRX to the network device 2, the network device 2 can also determine that the network device 3 is in an energy-saving state based on this. The network device 2 and the network device 2 can be adjacent network devices. For example, the network device 2 and the network device 3 are neighboring base stations, etc.

[0217] S502. The network device 2 sends a first piece of information. The first piece of information is used to indicate that the network device 3 is in an energy-saving state. Correspondingly, the terminal device receives the first piece of information.

[0218] It should be understood that the manner in which the eighth piece of information and the first piece of information indicate that the network device 3 is in an energy-saving state is similar to the manner in which the method 300 indicates that the network device 1 is in an energy-saving state. The configuration parameters of DTX and / or DRX indicated by the eighth piece of information are similar to the configuration parameters of DTX and / or DRX in the method 300. For details, reference can be made to the description of the method 300 and will not be elaborated here.

[0219] S503. The network device 3 sends public information. Correspondingly, the terminal device receives the public information from the network device 3.

[0220] It should be understood that the public information can indicate a synchronization information block, etc. The public information can be referred to the description in the method 300 and will not be elaborated here.

[0221] Indicate to the terminal device through network device 2 that network device 3 is in the energy-saving state. In this way, the terminal device can adopt corresponding strategies to listen for public information sent by network device 3, which helps the terminal device accurately obtain public information such as synchronization information blocks from network device 3, and thus helps the terminal device access the cell served by network device 3.

[0222] As an optional embodiment, method 500 further includes: network device 2 sends seventh information to the terminal device. Correspondingly, the terminal device receives the seventh information from network device 2. The seventh information is used to indicate one or more of the following: the updated priority of the first cell, the updated priority is lower than the original priority of the first cell, and the first cell is the cell served by network device 3; or, listen for the synchronization signal block from network device 3 using the fifth period; or, the configuration parameters of DTX and / or DRX of network device 3; or, reside in the first cell during the DTX on-time and / or DRX on-time.

[0223] It should be understood that network device 2 can set the priority of the first cell served by network device 3. In this way, when the terminal device performs cell selection, since the updated priority of the first cell is lower, the possibility for the terminal device to select the first cell is reduced. The seventh information can be a sixth preset identifier, such as 02, etc. 02 can indicate that the priority of the first cell is adjusted from the first level to the third level, or the priority of the first cell is reduced by 2 levels, etc.

[0224] Assume that when network device 3 is not in the energy-saving state, the period for the terminal device to listen for the synchronization information block of network device 3 is the sixth period. Then the fifth period can be greater than the sixth period. That is, when network device 3 is in the energy-saving state, network device 2 instructs the terminal device to listen for the synchronization information block with a larger period. In this way, it is convenient for the terminal device to search for the synchronization information block for a longer time, which helps the terminal device to reside in network device 3.

[0225] It should be understood that the manner in which the seventh information indicates the fifth period can refer to the manner in which the third period is indicated in method 300, which will not be elaborated here.

[0226] It should be noted that network device 3 can also send public information according to the first configuration in method 300. Correspondingly, the terminal device listens for the public information from network device 3 according to the first configuration. Among them, the first configuration can be configured by network device 2 through signaling or can also be a protocol agreement. For the specific content of the first configuration and the manner in which network device 2 configures the first configuration through signaling, reference can be made to the description in method 300, which will not be elaborated here.

[0227] Optionally, method 500 further includes: The network device 3 sends information for indicating the seventh information and / or the first configuration to the network device 2. Correspondingly, the network device 2 receives the information for indicating the seventh information and / or the first configuration from the network device 3. In this way, the network device 2 can determine information such as the configuration parameters of the DTX of the network device 3 and / or the configuration parameters of the DRX, and the first configuration, which facilitates the network device 2 to indicate the first configuration and / or the seventh information to the terminal device.

[0228] It should be understood that the information for indicating the seventh information and / or the first configuration and the eighth information may be sent through one signaling or through different signalings. And in the case where the information for indicating the seventh information and / or the first configuration and the eighth information are sent through one signaling, the information for indicating the seventh information and / or the first configuration and the eighth information may be carried in the same or different fields of the signaling, or the information for indicating the seventh information and / or the first configuration and the eighth information may be carried in the same or different cells of the signaling. The present application does not make specific limitations on this.

[0229] Optionally, the seventh information and / or the first configuration may also be agreed upon by the protocol. In this way, after receiving the eighth information, the network device 2 can determine information such as the configuration parameters of the DTX of the network device 3 and / or the configuration parameters of the DRX, and the first configuration, so as to directly indicate the first configuration and / or the seventh information to the terminal device.

[0230] In addition, the terminal device can determine the DTX start time and / or the DRX start time, and the DTX stop time and / or the DRX stop time through the configuration parameters of the DTX of the network device 3 and / or the configuration parameters of the DRX of the network device 3.

[0231] Since in the case where the network device 2 instructs the terminal device to camp on the first cell at the DTX start time and / or the DRX start time, the terminal device needs to determine the DTX start time and / or the DRX start time of the network device 3, and the DTX stop time and / or the DRX stop time of the network device 3. Therefore, the seventh information may include the configuration parameters of the DTX of the network device 3 and / or the configuration parameters of the DRX of the network device 3, and camping on the first cell at the DTX start time and / or the DRX start time. Optionally, the configuration parameters of the DTX of the network device 3 and / or the configuration parameters of the DRX of the network device 3, and camping on the first cell at the DTX start time and / or the DRX start time may also be indicated by different signalings. For example, the eighth information indicates camping on the first cell at the DTX start time and / or the DRX start time; then the network device 2 further sends information 4 to the terminal device, and the information 4 is used to indicate the configuration parameters of the DTX of the network device 3 and / or the configuration parameters of the DRX of the network device 3. The information 4 and the seventh information may be indicated by different signalings.

[0232] Since the cycle of the network device 3 for sending and receiving information may be smaller during the DTX start time and / or the DRX start time, therefore, by instructing the terminal device to camp on the first cell during the DTX start time and / or the DRX start time, it helps to improve the success rate of the terminal device camping on the first cell.

[0233] It should be noted that since the terminal device needs to determine the start time of the system frame of the network device 3 to determine the DTX start time and / or the DRX start time of the network device 3, therefore, before the terminal device determines the DTX start time and / or the DRX start time of the network device 3, the network device 3 may broadcast a common information block. Correspondingly, the terminal device receives the common information block from the network device 3.
