Description

Information transmission methods and transmission devices

[0001] This application claims priority to Chinese Patent Application No. 202311735718.0, filed on December 15, 2023, entitled "Information Transmission Method and Transmission Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and particularly to information transmission methods and devices in the field of communications. Background Technology

[0003] Discontinuous transmission (DTX) / discontinuous reception (DRX) technology is one of the important technologies for achieving energy saving in network devices and terminal devices. For example, a network device can instruct a terminal device to activate DTX / DRX. By activating DTX / DRX, the network device and terminal device can transmit data during the DTX / DRX activation period and not transmit data during the DTX / DRX deactivation period, thereby achieving energy saving for both network devices and terminal devices.

[0004] However, this method of information transmission still results in poor energy efficiency for network and terminal devices. Summary of the Invention

[0005] This application provides an information transmission method and transmission device that can improve the energy-saving effect of network equipment and terminal equipment.

[0006] In a first aspect, an information transmission method is provided, the method comprising: receiving first information, the first information being used to indicate that a first network device is in a power-saving state, the power-saving state including discontinuous transmission DTX being active and / or discontinuous reception DRX being active; and based on the first information, listening to public information, the public information including at least one of the following: system information, synchronization signal block, paging message or paging early indication.

[0007] In one possible implementation, the method is executed by a terminal device or a chip within the terminal device.

[0008] It should be understood that, in one scenario, the first network device can be network device 1 as described in this application, meaning network device 1 indicates to the terminal device that network device 1 is in a power-saving state. In another scenario, the first network device can be network device 3 as described in this application, meaning network device 2 indicates to the terminal device that network device 3 is in a power-saving state.

[0009] The information transmission method of this application, when the network device is in an energy-saving state, broadcasts public information using a strategy that is more conducive to energy conservation, such as broadcasting public information with a longer interval. Simultaneously, it instructs the terminal device to also be in an energy-saving state, enabling the terminal device to listen to the public information using a corresponding strategy, thus improving the energy-saving effect of both the network device and the terminal device. Furthermore, the terminal device can promptly determine changes in the network device's state and the strategy for broadcasting public information, ensuring that it receives public information according to the correct strategy.

[0010] In conjunction 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, the second information being used to indicate changes in system information; receiving the first information includes: in response to the second information, monitoring system information and receiving the first information.

[0011] It should be understood that the second information could be, for example, a short message, with a 1 bit in the message indicating a change in system information. In response to the second information, the terminal device can re-listen for system information and determine, based on the system information, that the first network device is in power-saving mode.

[0012] In conjunction with the first aspect, in some embodiments of the first aspect, monitoring public information includes: monitoring public information according to a first configuration; wherein the first configuration includes one or more of the following: a first period; not monitoring a first type of public information; monitoring other types of public information after receiving an early paging indication; monitoring the public information according to a third period during the DTX on-time and / or DRX on-time; or, monitoring the public information according to a fourth period or irregular time interval during the DTX off-time and / or DRX off-time. In this way, the first network device broadcasts public information according to the policy corresponding to the first configuration, and the terminal device can use the policy corresponding to the first configuration to monitor public information, resulting in better energy-saving performance for both the first network device and the terminal device.

[0013] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: receiving third information from a first network device, the third information being used to indicate a first configuration. In this way, the first network device can flexibly determine the first configuration and send it to a terminal device, enabling the terminal device to listen to public information according to the first configuration, which helps to save energy for both the first network device and the terminal device.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the first period is determined by the second period and N, the second period being the period during which public information is listened to when DTX is in a deactivated state and / or DRX is in a deactivated state, and the first period is N times the second period, where N is a positive number.

[0015] It should be understood that N can also be interpreted as a scaling factor for the second period. N can be, for example, 2, 3, or 4. In this way, the first network device can indicate N to the terminal device, allowing the terminal device to determine the first period based on N and the second period, which helps reduce signaling overhead.

[0016] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: receiving fourth information from a first network device, the fourth information indicating configuration parameters for DTX and / or DRX, the configuration parameters including at least one of the following: DTX period and / or DRX period, duration of DTX activation time and / or duration of DRX activation time, or start time interval of DTX and / or start time interval of DRX. In this way, the terminal device can determine the DTX activation time and / or DRX activation time, as well as the DTX deactivation time and / or DRX deactivation time. This facilitates the terminal device to employ a certain strategy to monitor public information during the DTX activation time and / or DRX activation time, and to employ other strategies to monitor public information during the DTX deactivation time and / or DRX deactivation time.

[0017] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: sending fifth information to the first network device based on the first information, the fifth information being used to request random access.

[0018] It should be understood that the fifth piece of information could be, for example, a random access request or a random access signal. When the terminal device determines that the first network device is in an energy-saving state, such as when the first network device's DRX is active, the terminal device can use a corresponding strategy to send the fifth piece of information. This helps improve the energy-saving effect of both the terminal device and the first network device. For example, the terminal device can send the fifth piece of information when DRX is enabled.

[0019] In conjunction 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; wherein the second configuration includes one or more of the following: sending the fifth information during the DTX enable time and / or DRX enable time; or, sending the fifth information after receiving the second type of public information; or, sending the fifth information on a first time-frequency domain resource; or, sending the fifth information on a second time-frequency domain resource during the DTX disable time and / or DRX disable time; or, sending the fifth information after receiving the second type of public information during the DTX disable time and / or DRX disable time. In this way, the terminal device can send the fifth information according to the second configuration. This helps improve the success rate of the terminal device accessing the first network device and also helps improve the energy-saving effect of the first network device and the terminal device.

[0020] Optionally, the second configuration may be configured by the first network device via signaling or agreed upon by a protocol.

[0021] Optionally, the method further includes: receiving information 1 from a first network device, information 1 being used to instruct the terminal device to send uplink information during time period 1 of the DRX shutdown time and / or time period 1 of the DTX shutdown time. Wherein, time period 1 belongs to a portion of the DRX shutdown time and / or time period 1 belongs to a portion of the DTX shutdown time. Time period 1 can be a period of time after the start of the DRX shutdown time and / or after the start of the DTX shutdown time, for example, within two time slots after the start of the DRX shutdown time. Alternatively, time period 1 can be a period of time after a certain time following the start of the DRX shutdown time and / or a period of time after a certain time following the start of the DTX shutdown time, for example, a period of time after two time slots following the start of the DRX shutdown time.

[0022] Optionally, time period 1 can be agreed upon by the protocol or configured by the first network device via signaling.

[0023] Optionally, the method further includes: receiving information 2 from a first network device, information 2 indicating DRX configuration parameters, the DRX configuration parameters including at least one of the following: DRX period, duration of DRX activation time, or DRX start time interval. Thus, the terminal device can determine the DRX activation time based on the DRX configuration parameters, thereby transmitting uplink information during the DRX activation time, or sending uplink information during time period 1 of the DRX deactivation time and / or time period 1 of the DTX deactivation time.

The above-mentioned network equipment can also be a city base station, micro base station, pico base station, femtobase station, etc. This application does not limit this.

[0076] First, let's introduce some of the technical terms used in this application.

[0077] 1. The synchronization signal block (PBCH block, SSB) is fundamental for cell search. Synchronization signals include the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). The PSS / SSS, together with the physical broadcast channel (PBCH), form the synchronization signal block SSB. The master information block (MIB) is transmitted on the PBCH, and terminal devices obtain system information block (SIB) information by reading the MIB information.

[0078] The MIB is used to carry scheduling information for system information blocks, etc.

[0079] 2. System messages include various information used by network devices to notify terminal devices about the system, such as network information of the cell where the terminal device is located, registration area information, public channel information, and information about other cells, etc. System messages include SIB1 and other system information blocks (OSI).

[0080] SIB1 is used to carry cell selection information, access control information, initial access-related channel configuration information, and scheduling information for the remaining system information blocks, which contain specific data. System messages are carried on a set of radio frames and can be broadcast via the broadcast channel (BCH). The BCH is a one-way control channel that can broadcast common cell information and consists of a frequency correction channel (FCCH), a synchronization channel (SCH), and a broadcast control channel (BCCH).

[0081] 3. Paging messages can include short message paging messages and paging terminal paging messages.

[0082] Paging messages, such as those for short messages, can indicate system information updates or earthquake / tsunami warnings. Terminal devices in the Radio Resource Control (RRC) idle, inactive, and connected states must receive these short message messages. Paging messages for paging terminals can include multiple paging UE IDs. If a terminal device determines that it has been paged by the network device if it finds a matching paging UE ID among the multiple paging UE IDs in the paging message, it can then access the network device through random access procedures. For paging messages for paging terminals, terminal devices in the RRC idle and inactive states must receive these messages, while terminal devices in the RRC connected state do not need to receive them.

[0083] 4. Short message paging messages, also known as short messages, can consist of 8 bits, each of which can be used to indicate different information. For example, bit 1 indicates whether the system information has changed (e.g., bit 1 being 1 indicates a system information change); bit 2 indicates an earthquake or typhoon alarm notification (e.g., bit 2 being 1 indicates an earthquake or typhoon alarm); bit 3 indicates whether paging monitoring has stopped (e.g., bit 3 being 1 indicates stopping monitoring of PDCCH paging during this paging period). Other bits can be reserved.

[0084] 5. Paging early indication (PEI) is used to instruct terminal equipment to listen for paging messages.

[0085] It should be understood that if the PEI indicates that paging messages need to be received during the paging period, then the terminal device needs to receive paging messages during the corresponding paging period; if the PEI indicates that paging messages do not need to be listened to during the paging period, then the terminal device does not need to listen to paging messages during the paging period.

[0086] 6. Discontinuous transmission (DTX) / discontinuous reception (DRX) is a network energy-saving technology.

[0087] Network devices can activate or deactivate DTX / DRX, meaning DTX / DRX can be in an active or deactivated state. When DTX / DRX is active, it means that the network device and the terminal device are communicating using DTX / DRX technology. Conversely, when DTX / DRX is deactivated, it means that the network device and the terminal device are not communicating using DTX / DRX technology.

[0088] When DTX / DRX can be active, network devices and terminal devices can transmit data during DTX on time / DRX on time; and do not transmit data during DTX off time / DRX off time.

[0089] For example, Figure 1 is a schematic diagram of DTX being active (or DRX being active). When DTX is active, the DTX on time (or DRX on time) can be represented by the raised portion in Figure 1, and the DTX off time (or DRX off time) can be represented by the recessed portion in Figure 1. The DTX cycle (or DRX cycle) can refer to the time interval between two adjacent moments when the DTX on time (or DRX on time) begins, or the DTX cycle (or DRX cycle) can refer to the time interval between two adjacent moments when the DTX off time (or DRX off time) begins.

[0090] During DTX enabled periods, network devices can transmit downlink information, and correspondingly, terminal devices can listen to / receive downlink information from the network devices. During DTX disabled periods, network devices do not transmit downlink data, and terminal devices do not need to listen to downlink information from the network devices. Similarly, when DRX is activated, during DRX enabled periods, terminal devices can send uplink information to the network devices, and correspondingly, the network devices can listen to / receive uplink data from the network devices. During DRX disabled periods, terminal devices do not send uplink information to the network devices, and correspondingly, the network devices do not listen to / receive uplink data transmissions from the terminal devices. Thus, during DRX disabled and / or DTX disabled periods, the power consumption of both network devices and terminal devices is low. Therefore, when DTX / DRX is active, the network devices can be considered to be in an energy-saving state.

[0091] It should be understood that, in the embodiments of this 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 called the enabled state, and the deactivated state can also be called the disabled state. Correspondingly, activating DTX / DRX can also be called enabling DTX / DRX, and deactivating DTX / DRX can also be called disabling DTX / DRX. In addition, DTX start time / DRX start time can also be called DTX activation time / DRX activation time, and DTX stop time / DRX stop time can also be called DTX deactivation time / DRX deactivation time. This application does not specifically limit these terms.

[0092] To facilitate understanding of the embodiments of this application, the communication system applicable to the embodiments of this application will be described in detail first with reference to FIG2 and FIG3.

[0093] Figure 2 is a schematic diagram of a communication system 200 applied in an embodiment of this application. The communication system 200 may include at least one network device, such as network device 210 shown in Figure 2; the communication system 200 may also include at least one terminal device, such as terminal device 220 shown in Figure 2. Network device 210 and terminal device 220 can communicate via a wireless link. In one possible scenario, network device 210 can act as a transmitter and terminal device 220 can act as a receiver, with network device 210 sending signals to terminal device 220; in another possible scenario, network device 210 can act as a receiver and terminal device 220 can act as a transmitter, with terminal device 220 sending signals to network device 210.

[0094] Figure 2 exemplarily illustrates a network device 210 and a terminal device 220. Optionally, the communication system 200 may further include multiple network devices and / or multiple terminal devices. The network device 210 may be a router, base station, etc., and the terminal device 220 may be a mobile phone, tablet computer, smart bracelet, etc., which are not limited in this application embodiment.

[0095] The aforementioned communication devices, such as network device 210 or terminal device 220 in Figure 2, can be configured with multiple antennas. These multiple antennas may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. Additionally, each communication device also includes a transmitter chain and a receiver chain, which, as will be understood by those skilled in the art, may include multiple components related to signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, or antennas). Therefore, network device 210 and terminal device 220 can communicate via multi-antenna technology.

[0096] Optionally, the communication system 200 may also include other network entities such as a network controller and a mobility management entity, but the embodiments of this application are not limited thereto.

[0097] It should also be understood that the method provided in the embodiments of this application can be applied to a variety of communication systems, including 5G new radio (NR) systems. Communication system 200 is only an example. This application does not limit the specific architecture of the applicable system, nor does it limit the number and form of various devices contained in each communication system.

[0098] Currently, when DTX / DRX is active, regardless of whether it's during DTX / DRX on / off time or DTX off time, network devices broadcast common information, such as system information and paging messages, at the same interval. Correspondingly, terminal devices also need to listen for the common information broadcast by network devices at the same interval. This information transmission method results in poor energy efficiency for both network and terminal devices.

[0099] To address the aforementioned technical problems, this application provides an information transmission method. When DTX / DRX is active, the network device can broadcast public information using a specific strategy, such as a longer broadcast period than when DTX / DRX is deactivated, thereby improving the network device's energy efficiency. Furthermore, when DTX / DRX is active, the network device can instruct terminal devices to enter an energy-saving state, allowing terminal devices to also listen for public information according to a corresponding strategy. This reduces the number of times terminal devices need to listen for public information, further enhancing their energy efficiency.

[0100] The information transmission method of this application will be described in detail below with reference to Figures 3 to 5. The embodiments shown in this application illustrate the information transmission method provided by this application from the perspective of device interaction. The specific form and number of each device shown are merely examples and should not constitute any limitation on the implementation of the method provided by this application. Below, the information transmission method of the embodiments of this application will be described in detail using terminal devices and network devices as the execution subjects.

[0101] It should be understood that the terminal device can be the terminal device itself, a chip, chip system or processor that supports the terminal device in implementing data transmission methods, or a logic module or software that can implement all or part of the terminal device; the network device can be the network device itself, a chip, chip system or processor that supports the network device in implementing data transmission methods, or a logic module or software that can implement all or part of the network device, and this application does not make any specific limitations in this regard.

[0102] Figure 3 is a schematic flowchart of an information transmission method 300 provided in an embodiment of this application. Method 300 can be applied to a system including terminal devices and network devices, such as system 200. The network device can be, for example, network device 1 as shown in Figure 3. The terminal device can be an idle or inactive terminal device.

[0103] Method 300 includes the following steps:

[0104] S301, Network device 1 sends first information. Correspondingly, terminal device receives the first information. The first information is used to indicate that network device 1 is in power-saving mode, which includes DTX being active and / or DRX being active.

[0105] In this application, network device 1 can indicate that it is in a power-saving state in various ways. For example, the first information may include a preset identifier, such as 1 or on, which can be used to indicate that network device 1 is in a power-saving state; or, the message corresponding to the first information may itself be used to indicate that network device 1 is in a power-saving state. This application does not limit the specific form of the first information.

[0106] It should be noted that both DTX and / or DRX being in an active state are considered power-saving states. This application's embodiments can be applied to situations where network device 1's DTX is active, and / or network device 1's DRX is active; this application does not specifically limit this.

[0107] Optionally, the first information can be carried in a short message, for example, bit 4, bit 5, or bit 6 in the short message. Assuming the fourth information is bit 4 in the short message, when bit 4 in the short message is 1 or 0, it can indicate that network device 1 is in a power-saving state.

[0108] S302, Network device 1 sends public information. Correspondingly, terminal device listens for and receives public information. Public information includes at least one of the following: system information, synchronization signal block, paging message, or paging early indication.

[0109] It should be understood that random access time-frequency domain resource information can be information used to indicate random access time-frequency domain resources, and random access pilot information can be information used to indicate random access pilots. Random access time-frequency domain resource information and random access pilots can be sent in a single signaling message or in separate signaling messages. The strategy adopted by network device 1 for sending common information can differ from the strategy adopted when DTX is in an inactive state and / or DRX is in an inactive state. Furthermore, compared to the strategy adopted when DTX is in an inactive state and / or DRX is in an inactive state, the strategy adopted by network device 1 for sending common information when DTX is in an active state and / or DRX is in an active state is a strategy that makes the network device more energy-efficient.

[0110] It should be noted that if the DTX of network device 1 is active, the strategy adopted by network device 1 to send public information may be related to the configuration parameters of DTX; if the DRX of network device 1 is active, the strategy adopted by network device 1 to send public information may be related to the configuration parameters of DRX; if both the DRX and DTX of network device 1 are active, the strategy adopted by network device 1 to send public information 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.

[0111] It should also be noted that, in the embodiments of this application, public information includes, but is not limited to, the following: system information, synchronization signal blocks, paging messages, or paging early indications. For example, public information may also be other information transmitted through the physical downlink control channel (PDCCH). This application does not specifically limit this.

[0112] The information transmission method of this application, when the network device is in an energy-saving state, broadcasts public information using a strategy that is more conducive to energy conservation, such as broadcasting public information with a longer interval. Simultaneously, it instructs the terminal device to also be in an energy-saving state, enabling the terminal device to listen to the public information using a corresponding strategy, thus improving the energy-saving effect of both the network device and the terminal device. Furthermore, the terminal device can promptly determine changes in the network device's state and the strategy for broadcasting public information, ensuring that it receives public information according to the correct strategy.

[0113] As an optional embodiment, the first information may be system information, then method 300 further includes: network device 1 sending second information to terminal device, the second information being used to indicate changes in system information; S301 can be implemented in the following manner: in response to the second information, network device 1 sends the first information.

[0114] It should be understood that the second message could be, for example, a short message, in which a bit 1 indicates a change in system information. In response to the second message, the terminal device can re-listen for system information and determine, based on the system information, that network device 1 is in a power-saving state.

[0115] It should be understood that, in addition to system information, the first information can also be carried in downlink messages sent via PDCCH, and this application does not specifically limit this.

[0116] The following describes the policies for network device 1 to send public information and the policies for terminal devices to listen to public information when network device 1 is in power-saving mode. These policies can be divided into two cases: in one case, the policy can be implemented without relying on the configuration parameters of DTX and / or DRX, such as the first configurations 1 to 7 described below; in the other case, the policy is implemented based on the configuration parameters of DTX and / or DRX, such as the first configurations 8 to 10 described below.

[0117] As an optional embodiment, S302 can be implemented in the following manner: 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 cycle; not sending the first type of public information; sending other types of public information after sending an early paging indication; during the DTX on time and / or DRX on time, network device 1 sends public information according to a third cycle, and correspondingly, the terminal device listens for public information according to the third cycle; or, during the DTX off time and / or DRX off time, network device 1 sends public information according to a fourth cycle or an irregular time interval, and correspondingly, the terminal device listens for public information according to the fourth cycle or an irregular time interval.

[0118] The first configuration can be understood as the strategy for network device 1 to send public information or the strategy for terminal devices to listen to public information.

[0119] The first configuration is the first cycle.

[0120] The first period is a positive number. The first period can be longer than the period used by network device 1 when broadcasting public information in a non-energy-saving state. For example, if the period used by network device 1 when broadcasting public information in a non-energy-saving state is 10ms, then the first period can be 15ms, 30ms, etc.

[0121] In this way, network device 1 can broadcast public information at longer intervals, and terminal devices can listen to public information at longer intervals, resulting in better energy-saving performance for both network device 1 and terminal devices.

[0122] The second configuration, the first setting, is to not 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 types, such as system information, synchronization signal blocks, paging messages, or random access messages. Random access messages can include random access time-frequency domain resource information and / or random access pilot information. Correspondingly, for the terminal device, the first configuration is to not listen to the first type of public information in the public information.

[0123] In this way, network device 1 can refrain from sending the first type of public information, and terminal devices can refrain from listening to the first type of public information, thus improving the energy efficiency of both network device 1 and terminal devices.

[0124] The third option is to send other types of public information after sending the early paging indication. These other types of public information are information other than the early paging indication, such as paging messages and system information. Correspondingly, for the terminal device, the first configuration is to listen for other types of public information only after receiving the early paging indication.

[0125] In this way, the terminal device can refrain from listening to other types of public information before receiving the paging early indication, and then listen to other types of public information after receiving the paging early indication, thus improving the energy efficiency of the terminal device.

[0126] Optionally, the paging early indication may carry information indicating the monitoring of other types of public information. For example, the paging early indication may carry information indicating the monitoring of paging messages or public information. For instance, the paging early indication may use bit information to indicate the monitoring of paging messages or public information; a bit of 11 may indicate monitoring of public information, a bit of 00 may indicate monitoring of paging messages, and a bit of 10 may indicate monitoring of both public information and paging messages, etc.

[0127] In this way, the terminal device can refrain from listening to other types of public information before receiving the paging early indication. After receiving the paging early indication, it can listen to other types of public information based on the information carried in the paging early indication that indicates the need to listen to other types of public information, thus improving the energy-saving effect of the terminal device.

[0128] Optionally, network device 1 sends information to terminal device to indicate other types of public information. This information may be, for example, bit information; a bit of 11 may indicate listening to public information, a bit of 00 may indicate listening to paging messages, and a bit of 10 may indicate listening to both public information and paging messages.

[0129] It should be understood that the public information used to indicate other types of information and paging early instructions can be sent via the same signaling or different signaling, and this application does not specifically limit this.

[0130] It should be noted that in some possible implementations, the paging early indication can also be replaced by a newly defined listening indication information, that is, a signaling different from the paging early indication. For example, the newly defined listening indication information can be a downlink message sent through the PDCCH. This application does not specifically limit the content or format of the listening indication information.

[0131] The fourth configuration is the first type of public information in the first cycle and no public information transmission. That is, network device 1 transmits other types of public information in the first cycle while not transmitting the first type of public information.

[0132] In this way, network device 1 can broadcast public information with a longer period, terminal device can listen to public information with a longer period, and network device 1 can choose not to send the first type of public information, and terminal device can choose not to listen to the first type of public information, thus making the energy-saving effect of network device 1 and terminal device better.

[0133] The fifth configuration, the first setting, involves sending the paging early indication in the first cycle, followed by sending other types of public information. That is, the terminal device listens for the paging early indication only after receiving the paging early indication. Furthermore, network device 1 sends the paging early indication and / or other types of public information in the first cycle, and the terminal device listens for the paging early indication and / or other types of public information in the first cycle.

[0134] In this way, network device 1 can broadcast public information at a longer interval, terminal devices can listen to public information at a longer interval, and terminal devices can refrain from listening to other types of public information before listening to the paging early indication, thus making network device 1 and terminal devices more energy-efficient.

[0135] The sixth configuration, the first configuration, is to not send the first type of public information in the public information and to send the remaining types of public information after sending the paging early indication.

[0136] In this way, network device 1 can refrain from sending the first type of public information, terminal device can refrain from listening to the first type of public information, and terminal device can refrain from listening to other types of public information before listening to the paging early indication, thus making network device 1 and terminal device more energy-efficient.

[0137] The seventh type is configured as the first cycle, not sending the first type of public information in the public information, and sending the other types of public information after sending the paging early indication.

[0138] In this way, network device 1 can broadcast public information with a longer period, and terminal device can listen to public information with a longer period; network device 1 can choose not to send the first type of public information, and terminal device can choose not to listen to the first type of public information; and terminal device can choose not to listen to other types of public information before listening to the paging early indication, so that network device 1 and terminal device have better energy saving effect.

[0139] The eighth configuration, the first configuration, is that during the DTX enable time and / or DRX enable time, network device 1 sends public information according to the third cycle, and correspondingly, terminal device listens to public information according to the third cycle; and / or, during the DTX disable time and / or DRX disable time, network device 1 sends public information according to the fourth cycle or irregular time interval, and correspondingly, terminal device listens to public information according to the fourth cycle or irregular time interval.

[0140] The third period can be the same as the second period, that is, the period during which public information is listened to when DTX is in an inactive state and / or DRX is in an inactive 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 longer than the third period; for example, the third period is 10ms and the fourth period is 30ms. Alternatively, the fourth period can be M times the third period, where M is a positive integer. For example, as shown in Figure 4, M is 2, and the time when network device 1 sends public information or the terminal device listens to public information can be the time indicated by the solid arrow in Figure 4. At the time indicated by the dashed arrow, network device 1 does not send public information, and the terminal device does not listen to public information.

[0141] Irregular time intervals can be understood as multiple time intervals during which network device 1 sends public information within a DTX shutdown time (or DRX shutdown time) are not entirely the same, meaning that multiple time intervals during which the terminal device listens for public information are not entirely the same. Each of these multiple time intervals is the time interval between two consecutive times when network device 1 sends public information.

[0142] In the first example, within a DTX shutdown period (or DRX shutdown period), the second time interval for network device 1 to send public information is twice the first time interval, the third time interval is three times the first time interval, the fourth time interval is four times the first time interval, and so on. The first time interval for network device 1 to send public information can be understood as the time interval between the first and second times of sending public information after entering the DTX shutdown period (or DRX shutdown period). The second time interval for network device 1 to send public information is the time interval adjacent to the first time interval, that is, the time interval between the second and third times of sending public information, and so on.

[0143] In the second example, within a DTX shutdown period (or DRX shutdown period), the second time interval for network device 1 to send public information is half the first time interval, the third time interval is one-third the first time interval, the fourth time interval is one-quarter the first time interval, and so on. The explanations for the first, second, third, and fourth time intervals are the same as in the first example and can be found in the description above; they will not be repeated here.

[0144] In the two examples above, 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 network device 1 via signaling.

[0145] The ninth configuration, the first configuration, is that during the DTX enable time and / or DRX enable time, network device 1 sends public information according to the third cycle, and correspondingly, terminal device listens to public information according to the third cycle; and / or, during the DTX disable time and / or DRX disable time, network device 1 does not send the first type of public information in the public information and / or sends other types of public information after sending the paging early indication, and correspondingly, terminal device does not listen to the first type of public information in the public information and / or listens to other types of public information after listening to the paging early indication.

[0146] It should be understood that the third cycle may be the same as or different from the second cycle. The instructions to not send the first type of public information and / or to send other types of public information after sending the early paging instruction are described above and will not be repeated here.

[0147] The 10th configuration, the first configuration, is that during the DTX enable time and / or DRX enable time, network device 1 does not send the first type of public information in the public information, and correspondingly, the terminal device does not listen to the first type of public information in the public information; and / or, during the DTX disable time and / or DRX disable time, network device 1 sends the other types of public information after sending the paging early indication, and correspondingly, the terminal device listens to the other types of public information after listening to the paging early indication.

[0148] It should be understood that in this embodiment, the strategy of network device 1 to send public information during the DTX enable time and / or DRX enable time can be interchanged with the strategy of network device 1 to send public information during the DTX disable time and / or DRX disable time. For the sake of brevity, it will not be described in detail here.

[0149] It should be noted that the strategies included in the first configuration can also be arranged and combined in ways different from the above 10 methods. Regardless of which of the above strategies the first configuration is a combination of, its implementation method is similar to the above 10 implementation methods. Please refer to the description above, and they will not be listed one by one here.

[0150] Based on the above embodiments, the first configuration may be agreed upon by the protocol or configured by the network device 1 through signaling.

[0151] In a first possible implementation, the first configuration is configured by network device 1 via signaling: method 300 further includes: network device 1 sending third information to terminal device, the third information being used to indicate the first configuration.

[0152] It should be understood that the third information and the first information (or) may be sent via a single signaling message or via different signaling messages. When the third information and the first information are sent via a single signaling message, the third information and the first information may be carried in the same or different information elements of that signaling message, or the third information and the first information may be carried in the same or different fields of that signaling message. This application does not impose specific limitations in this regard.

[0153] In this way, network device 1 can flexibly determine the first configuration and send the first configuration to the terminal device, so that the terminal device can listen to public information according to the first configuration, which helps to save energy for both network device 1 and terminal device.

[0154] Optionally, the third information and / or the first information can be carried in the system information. Alternatively, the third information can also be carried in the RRC release message. The third information can be configured when network device 1 releases the terminal device to the RRC idle state or the RRC inactive state.

[0155] The first cycle can be indicated in one of the following ways:

[0156] 1. The third information directly indicates the first cycle. For example, if the third information includes 20, 20 indicates that the first cycle is 20ms.

[0157] 2. The third piece of information includes a first preset identifier, which represents the first cycle. The preset identifier can be, for example, 0, 2, A1, or 1100. 0, 2, A1, or 1100 indicates that the first cycle is 20ms.

[0158] 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 during which public information is listened for when DTX is in a deactivated state and / or DRX is in a deactivated state. The first period is N times the second period, where N is a positive number.

[0159] It should be understood that N can also be interpreted as the scaling factor for the second period. N can be, for example, 2, 3, or 4.

[0160] In this way, the terminal device can determine the first cycle based on the second cycle and N.

[0161] When the third information includes N, the terminal device can know the second period. For example, the second period is agreed upon by the protocol, or the terminal device uses the second period to listen for public information before receiving the first information. In this way, 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 can determine the first period using the following formula: First period = N × Second period.

[0162] The information used to indicate N can be N itself, or it can be a second preset identifier. The second preset identifier can be, for example, 10, 01, 00, etc., where 10 can indicate N as 2, 01 can indicate N as 4, 00 can indicate N as 6, etc.

[0163] It should be noted that there can be multiple first cycles. For example, the first cycle may include the cycle of system information, the cycle of synchronization information block, and the cycle of paging message, etc. Correspondingly, there can also be multiple N. For example, N may include the cycle scaling factor corresponding to system information, the cycle scaling factor of paging message, etc. This application does not make specific limitations on this.

[0164] In one example, the first information is system information, which differs from the system information sent by network device 1 when both DTX and DRX are inactive. This first information also includes an additional first cycle, which comprises: the transmission cycle of synchronization information blocks (e.g., ssb-periodicity serving cell-nes ms40); the transmission cycle of paging messages (e.g., paging cycle-nes rf64); and the transmission cycle of system information (e.g., si-periodicity-nes rf64). Specifically, ssb-periodicity serving cell-nes ms40 indicates that the transmission cycle of the additionally configured synchronization information blocks in this system information is 40ms; paging cycle-nes rf64 indicates that the transmission cycle of the additionally configured paging messages in this system information is 64 radio frames (RF); and si-periodicity-nes rf64 indicates that the transmission cycle of the additionally configured system information in this system information is 64 RF.

[0165] In another example, the first information is system information. This differs from the system information sent by network device 1 when both DTX and DRX are inactive. The first information also includes an additional configuration of N. For example, the system information sent by network device 1 when both DTX and DRX are inactive includes the transmission period of the synchronization information block (e.g., ssb-periodicity serving cell ms10) and the transmission period of the paging message (e.g., paging cycle rf32). Therefore, the first information, including the transmission periods of the synchronization information block and the paging message, also includes a scaling factor of 4 for the transmission period of the synchronization information block and a transmission period of 2 for the paging message. 4 and 2 can be understood as the aforementioned N.

[0166] Optionally, method 300 further includes: network device 1 sending information indicating a first period to terminal device. Correspondingly, terminal device receives information indicating the first period from network device 1. The manner in which the information indicating the first period indicates the first period can be referred to the manner in which the third information indicates the first period, and will not be repeated here.

[0167] It should be understood that the information used to indicate the first cycle and the third information can be sent through the same signaling or different signaling. When the information used to indicate the first cycle and the third information are sent through the same signaling, the information used to indicate the first cycle and the third information can be carried in the same or different fields, or the information used to indicate the first cycle and the third information can be carried in the same or different information cells. This application does not make any specific limitations on this.

[0168] Not sending the first type of public information and / or sending the remaining types of public information after sending the early paging instruction can be indicated by one or more of the following methods:

[0169] The third information includes information used to indicate the first type of public information, such as #SSB or 0011. #SSB can represent a synchronization information block, and the terminal device can determine that network device 1 will not send a synchronization information block based on #SSB. 0011 can represent system information, and the terminal device can determine that network device 1 will not send system information based on 0011.

[0170] The third information includes a third preset identifier, which is used to indicate that the first type of public information in the public information is not sent and / or that the remaining types of public information are sent after the paging early indication is sent. The third preset identifier can be, for example, 0, 1100, etc. For example, 1100 can indicate that system information is not sent.

[0171] Optionally, method 300 further includes: network device 1 sending information indicating the first type of public information to terminal device. Correspondingly, terminal device receives information indicating the first type of public information from network device 1. The manner in which the information indicating the first type of public information indicates the first type of public information can be referred to the manner in which the third information indicates the first type of public information, and will not be repeated here.

[0172] It should be understood that the information used to indicate the first type of public information and the third information can be sent via the same signaling or different signaling. Furthermore, when the information used to indicate the first type of public information and the third information are sent via the same signaling, the information used to indicate the first type of public information and the third information can be carried in the same or different fields, or in the same or different information cells. This application does not specifically limit this. In addition, the third period, and / or the fourth period, or irregular time intervals can be indicated in the following ways.

[0173] In one possible implementation, the third period, and / or, the fourth period, or the irregular time interval is indicated by network device 1 via signaling. Method 300 further includes: network device 1 sending information to the terminal device indicating the third period, and / or, the fourth period, or the irregular time interval. Correspondingly, the terminal device receives the information from network device 1 indicating the third period, and / or, the fourth period, or the irregular time interval.

[0174] It should be understood that when the third period is the same as the second period, the third period can be a period known to the terminal device. Network device 1 can indicate a fourth period or an irregular time interval to the terminal device. When the third period is different from the second period, network device 1 can indicate the third period, and the fourth period or an irregular time interval to the terminal device.

[0175] The information used to indicate the third period can be the third period itself, such as 10, where 10 indicates the third period is 10ms. Alternatively, the information can be a fourth preset identifier, such as 001, where 001 indicates the third period is 10ms. The indication method for the fourth period is similar to that for the third period and will not be repeated here. The information used to indicate irregular time intervals can be a fifth preset identifier, such as #1, where #1 indicates the irregular time interval is the time interval described in the first example above.

[0176] Optionally, information indicating the third period can be carried in the first field, and information indicating the fourth period or irregular time interval can be carried in the second field. In this way, the terminal device can determine the third period and the fourth period (or the third period and the irregular time interval) based on the fields carrying the information.

[0177] It should be understood that the third information and the information indicating the third period, and / or, the fourth period, or irregular time interval can be sent via a single signaling message or via different signaling messages. When the third information and the information indicating the third period, and / or, the fourth period, or irregular time interval are sent via a single signaling message, the third information and the information indicating the third period, and / or, the fourth period, or irregular time interval can be carried in the same or different cells of that signaling message, or the third information and the information indicating the third period, and / or, the fourth period, or irregular time interval can be carried in the same or different fields of that signaling message. This application does not specifically limit this.

[0178] In another possible implementation, the third period, and / or, the fourth period, or an irregular time interval is agreed upon by the protocol. Thus, after the terminal device determines the DTX enable time (or DRX enable time) and the DTX disable time (or DRX disable time), it can determine the strategy for monitoring public information based on the third period, and / or, the fourth period, or an irregular time interval, without requiring network device 1 to indicate the third period, and / or, the fourth period, or an irregular time interval, resulting in lower signaling overhead.

[0179] In the second possible implementation, the first configuration is agreed upon by the protocol.

[0180] In this way, when the terminal device determines that the network device 1 is in an energy-saving state, it can use the first configuration to listen for public information on its own without the network device 1 needing to instruct the first configuration through signaling, thus reducing signaling overhead.

[0181] Based on the above embodiments, as an optional embodiment, method 300 further includes: network device 1 sending fourth information to terminal device, the fourth information being used to indicate the configuration parameters of DTX and / or DRX, the configuration parameters including at least one of the following: DTX period and / or DRX period, duration of DTX start time and / or duration of DRX start time, or start time interval of DTX and / or start time interval of DRX.

[0182] It should be understood that the fourth information and the first information can be sent via a single signaling message or via different signaling messages. When the fourth information and the first information are sent via a single signaling message, they can be carried in the same or different information elements of that signaling message, or they can be carried in the same or different fields of that signaling message. This application does not impose specific limitations in this regard.

[0183] When DTX is active in the power-saving mode, the fourth information indicates the configuration parameters of DTX, and the terminal device can determine the DTX start time and DTX stop time based on the DTX configuration parameters. When DRX is active in the power-saving mode, the fourth information indicates the configuration parameters of DRX, and the terminal device can determine the DRX start time and DRX stop time based on the DRX configuration parameters. When both DTX and DRX are active in the power-saving mode, the fourth information indicates the configuration parameters of both DTX and DRX, and the terminal device can determine the DTX start time and DTX stop time based on the DTX configuration parameters, and determine the DRX start time and DRX stop time based on the DRX configuration parameters. The DTX configuration parameters include at least one of the following: DTX period, DTX start time duration, or DTX start time interval. The DRX configuration parameters include at least one of the following: DRX period, DRX start time duration, or DRX start time interval.

[0184] The duration of DTX activation time (or DRX activation time) can refer to the duration of a DTX activation time (DRX activation time), such as the duration represented by a single bump in Figure 1.

[0185] Optionally, the duration of the DTX shutdown time (or DRX shutdown time) can be determined by the DTX cycle (or DRX cycle) and the duration of the DTX on time (or DRX on time). For example, the duration of the DTX shutdown time (or DRX shutdown time) can be the difference between the DTX cycle (or DRX cycle) and the duration of the DTX on time (or DRX on time).

[0186] The start time interval can also be understood as the start time or start moment. It can also be understood as the time interval from the start point of the system frame. For example, the start time interval for DRX can be 5 time slots. Then, starting at the moment corresponding to 5 time slots after the start point of the system frame, network device 1 activates DRX.

[0187] By configuring the DTX and / or DRX parameters, the terminal device can determine the DTX enable time and / or DRX enable time, as well as the DTX disable time and / or DRX disable time. This allows the terminal device to employ a specific strategy to monitor public information during the DTX enable time and / or DRX enable time, and to employ other strategies to monitor public information during the DTX disable time and / or DRX disable time, without affecting the terminal device's normal monitoring of public information sent by network device 1. For example, network device 1 can send public information according to the first configuration of types 8 to 10 described above; correspondingly, after the terminal device determines the DTX enable time and / or DRX enable time, as well as the DTX disable time and / or DRX disable time, it can monitor public information from network device 1 according to the first configuration of types 8 to 10 described above. In this way, the terminal device can...

[0188] As an optional embodiment, method 300 further includes: sending a sixth message to network device 1, the sixth message being used to trigger network device 1 to broadcast at least one public message; network device 1 receiving the sixth message from terminal device and, in response to the sixth message, sending at least one public message; and terminal device receiving at least one public message.

[0189] Among these, at least one piece of public information may be, for example, a paging message, system information, etc. The sixth piece of information may include information indicating at least one piece of public information, such as 100, where 100 represents system information. Thus, network device 1 can determine to broadcast at least one piece of public information based on the information indicating at least one piece of public information.

[0190] In one possible implementation, the sixth message is sent during the first time period.

[0191] The first time period can be determined in the following ways: the start time and duration of the first time period, or the start time and end time of the first time period, etc.

[0192] Optionally, the first time period may be agreed upon by the protocol or indicated by network device 1 via signaling.

[0193] For example, network device 1 can send information to terminal device to indicate a first time period, and correspondingly, terminal device receives information from network device 1 to indicate the first time period.

[0194] The information used to indicate the first time period can be, for example, 001 and 002, where 001 represents the start time of the first time period and 002 represents the end time of the first time period.

[0195] Optionally, the first time period can be a time period belonging to the DTX shutdown time and / or DRX shutdown time. For example, the first time period is three consecutive orthogonal frequency division multiplexing (OFDM) symbols after entering the DTX shutdown time. That is, the terminal device can transmit the sixth information on the three OFDM symbols in each DTX shutdown time period. Correspondingly, the information used to indicate the first time period can be the information of the three OFDM symbols used for indication, such as #3, etc.

[0196] In addition to network device 1 sending public information according to the first configuration, the terminal device listens for public information according to the first configuration. The terminal device can also send uplink information according to the second configuration when it is determined that network device 1 is in power-saving mode.

[0197] As an optional embodiment, method 300 further includes: S303, based on the first information, the terminal device sends fifth information to the network device 1, the fifth information being used to request random access. Correspondingly, the network device 1 receives the fifth information from the terminal device.

[0198] It should be understood that the fifth piece of information may be, for example, a random access request or a random access signal. The fifth piece of information can be used for random access to network device 1. When the terminal device determines that the first network device is in an energy-saving state, such as when the first network device's DRX is active, the terminal device can use a corresponding strategy to send the fifth piece of information. This helps improve the energy-saving effect of both the terminal device and the first network device. For example, the terminal device can send the fifth piece of information during the DRX activation time.

[0199] In one possible implementation, S303 can be implemented as follows: the terminal device sends the fifth information according to the second configuration. The second configuration includes one or more of the following: the terminal device sends the fifth information to network device 1 during the DTX enable time and / or DRX enable time; the fifth information is sent after receiving second type public information, such as paging early indication; the fifth information is sent on the first time-frequency domain resource; the fifth information is sent on the second time-frequency domain resource during the DTX disable time and / or DRX disable time; or the fifth information is sent after receiving the second type public information during the DTX disable time and / or DRX disable time.

[0200] Correspondingly, network device 1 can receive the fifth information according to the second configuration. The second configuration for network device 1 to receive the fifth information includes one or more of the following: receiving the fifth information at the DTX enable time and / or DRX enable time; receiving the fifth information after sending the second type of common information, such as paging early indication; receiving the fifth information on the first time-frequency domain resource; receiving the fifth information on the second time-frequency domain resource at the DTX disable time and / or DRX disable time; or receiving the fifth information after sending the second type of common information at the DTX disable time and / or DRX disable time.

[0201] The first and / or second time-frequency domain resources can be configured by network device 1 via signaling, agreed upon by a protocol, or preset. Sending the fifth message on the second time-frequency domain resource during the DTX shutdown and / or DRX shutdown times can be understood as requiring the use of the second time-frequency domain resource if the terminal device sends the fifth message to network device 1 during these times. Sending the fifth message after receiving the second type of common information during the DTX shutdown and / or DRX shutdown times can be understood as requiring the terminal device to send the fifth message after receiving the second type of common information if it sends the fifth message to network device 1 during these times.

[0202] For example, the terminal device may send the fifth information to network device 1 during the DTX enable time and / or DRX enable time; it may also send the fifth information after receiving the second type of public information; or it may send the fifth information during the DTX enable time and / or DRX enable time, and after receiving the second type of public information. Other combinations of strategies in the second configuration are also possible, which will not be listed here.

[0203] This helps improve the success rate of terminal devices accessing network device 1, and also helps improve the energy-saving effect of network equipment and terminal devices.

[0204] The second configuration can be configured by network device 1 via signaling or agreed upon by a protocol. Details are as follows.

[0205] Optionally, method 300 further includes: network device 1 sending information 3 to terminal device, information 3 indicating a second configuration. Correspondingly, terminal device receives information 3 from network device 1. In this way, network device 1 can instruct terminal device when to send the fifth information, which helps to improve the success rate of terminal device accessing network device 1 and also helps to improve the energy-saving effect of network device and terminal device.

[0206] The second type of public information can be configured by network device 1 through signaling or agreed upon by protocol. The method by which network device 1 configures the second type of public information through signaling is similar to the method by which it configures the first type of public information, as described above, and will not be repeated here.

[0207] Optionally, method 300 further includes: receiving information 1 from the first network device 1, information 1 being used to instruct the terminal device to send uplink information during time period 1 of the DRX shutdown time and / or time period 1 of the DTX shutdown time. Wherein, time period 1 belongs to a portion of the DRX shutdown time and / or time period 1 belongs to a portion of the DTX shutdown time. Time period 1 can be a period of time after the start of the DRX shutdown time and / or after the start of the DTX shutdown time, for example, within two time slots after the start of the DRX shutdown time. Alternatively, time period 1 can be a period of time after a certain period following the start of the DRX shutdown time and / or a period of time after a certain period following the start of the DTX shutdown time, for example, a period of time after two time slots following the start of the DRX shutdown time.

[0208] Here, time period 1 can be understood, for example, as the time domain resources included in the second time-frequency domain resources mentioned above.

[0209] It should be understood that information 1 and information 3 can be sent via the same signaling or different signaling. When information 1 and information 3 are sent via the same signaling, they can be sent via the same field or different fields; information 1 and information 3 can also be sent via the same information cell or different information cells, and this application does not specifically limit this.

[0210] Optionally, time period 1 can be agreed upon by the protocol or configured by network device 1 through signaling.

[0211] In the above method 300, S302 can also be optional, that is, when the terminal device determines that the network device 1 is in an energy-saving state, the terminal device sends the fifth information to the network device 1 according to the second configuration. For the sake of brevity, the implementation method of this embodiment can be referred to above, and will not be repeated here.

[0212] It should be understood that in method 300, network device 1 can also be replaced by a first network device, and this application does not specifically limit the name of the network device.

[0213] To facilitate terminal devices accessing networks operating in energy-saving mode within a residential area, this application also provides an information transmission method. The details are as follows.

[0214] Figure 5 is a flowchart illustrating an information transmission method 500 provided in an embodiment of this application. Method 500 can be applied to a system including a terminal device and multiple network devices, such as system 200, which may include two network devices and one terminal device. The two network devices may be, for example, network device 2 and network device 3 as shown in Figure 5. The terminal device may be an idle or inactive terminal device.

[0215] Method 500 includes the following steps:

[0216] S501, Network device 3 sends an eighth message to Network device 2. The eighth message indicates that Network device 3 is in a power-saving state, and / or the configuration parameters of DTX and / or DRX of Network device 3. The configuration parameters include at least one of the following: DTX period and / or DRX period, duration of DTX activation time and / or duration of DRX activation time, or start time interval of DTX and / or start time interval of DRX. The power-saving state includes DTX being in an active state and / or DRX being in an active state. Correspondingly, Network device 2 receives the eighth message from Network device 3.

[0217] It should be understood that when network device 3 instructs network device 2 on the configuration parameters of DTX and / or DRX, network device 2 can also determine that network device 3 is in an energy-saving state based on this. Network device 2 and network device 3 can be adjacent network devices, for example, network device 2 and network device 3 are adjacent base stations, etc.

[0218] S502, network device 2 sends first information, which indicates that network device 3 is in power-saving mode. Correspondingly, terminal device receives the first information.

[0219] It should be understood that the way the eighth information and the first information indicate that network device 3 is in a power-saving state is similar to the way the method 300 indicates that network device 1 is in a power-saving state. The configuration parameters of DTX and / or DRX indicated by the eighth information are similar to the configuration parameters of DTX and / or DRX in method 300. Please refer to the description of method 300, which will not be repeated here.

[0220] S503, Network device 3 sends public information. Correspondingly, the terminal device receives public information from network device 3.

[0221] It should be understood that public information can indicate synchronization information blocks, etc. For a description of public information in method 300, please refer to that description; it will not be repeated here.

[0222] By instructing the terminal device that network device 3 is in power-saving mode, the terminal device can use corresponding strategies to listen for public information sent by network device 3. This helps the terminal device accurately obtain public information such as synchronization information blocks from network device 3, thereby facilitating the terminal device's access to the cell served by network device 3.

[0223] As an optional embodiment, method 500 further includes: network device 2 sending seventh information to terminal device, correspondingly, terminal device receiving 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 being lower than the original priority of the first cell, the first cell being a cell served by network device 3; or, using the fifth cycle to listen for synchronization signal blocks from network device 3; or, the configuration parameters of DTX and / or DRX of network device 3; or, camping on the first cell during the DTX enable time and / or DRX enable time.

[0224] It should be understood that network device 2 can set the priority of the first cell served by network device 3. Thus, when a terminal device selects a cell, the likelihood of it selecting the first cell is reduced because the updated priority of the first cell is lower. The seventh information can be a preset identifier for the sixth cell, such as 02. 02 can indicate that the priority of the first cell is adjusted from level one to level three, or that the priority of the first cell is reduced by two levels, etc.

[0225] Assuming that when network device 3 is not in power-saving mode, the period for the terminal device to listen to 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 power-saving mode, network device 2 instructs the terminal device to listen to the synchronization information block with a longer period. This allows the terminal device to use a longer time to search for the synchronization information block, which helps the terminal device to reside on network device 3.

[0226] It should be understood that the method by which the seventh information indicates the fifth cycle can be referred to the method of indicating the third cycle in method 300, and will not be repeated here.

[0227] 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 public information from network device 3 according to the first configuration. The first configuration can be configured by network device 2 via signaling or by a protocol agreement. For the specific content of the first configuration and the method by which network device 2 configures the first configuration via signaling, please refer to the description in method 300, which will not be repeated here.

[0228] Optionally, method 500 further includes: network device 3 sending information indicating the seventh information and / or the first configuration to network device 2, and correspondingly, network device 2 receiving the information indicating the seventh information and / or the first configuration from network device 3. In this way, network device 2 can determine the configuration parameters of network device 3's DTX and / or DRX, the first configuration, and other information, facilitating network device 2 to indicate the first configuration and / or the seventh information to the terminal device.

[0229] It should be understood that the information used to indicate the seventh information and / or the first configuration and the eighth information can be sent through a single signaling message or through different signaling messages. In the case where the information used to indicate the seventh information and / or the first configuration and the eighth information are sent through a single signaling message, the information used to indicate the seventh information and / or the first configuration and the eighth information can carry the same or different fields in the signaling message, or the information used to indicate the seventh information and / or the first configuration and the eighth information can carry the same or different information elements in the signaling message. This application does not make any specific limitations on this.

[0230] Optionally, the seventh information and / or the first configuration can also be agreed upon by the protocol. In this way, after receiving the eighth information, network device 2 can determine the configuration parameters of network device 3's DTX and / or DRX, the first configuration, and other information, and thus directly indicate the first configuration and / or the seventh information to the terminal device.

[0231] In addition, the terminal device can determine the DTX start time and / or DRX start time, as well as the DTX stop time and / or DRX stop time, by using the DTX configuration parameters and / or DRX configuration parameters of network device 3.

[0232] Since network device 2 instructs the terminal device to camp on the first cell during the DTX and / or DRX activation times, the terminal device needs to determine the DTX and / or DRX activation times, as well as the DTX and / or DRX deactivation times, of network device 3. Therefore, the seventh information may include the configuration parameters of network device 3's DTX and / or DRX, and the information regarding camping on the first cell during the DTX and / or DRX activation times. Optionally, the configuration parameters of network device 3's DTX and / or DRX, and the information regarding camping on the first cell during the DTX and / or DRX activation times, may also be indicated by different signaling methods. For example, the eighth information may indicate camping on the first cell during the DTX and / or DRX activation times; in this case, network device 2 may also send information 4 to the terminal device, which indicates the configuration parameters of network device 3's DTX and / or DRX. Information 4 and the seventh information may be indicated by different signaling methods.

[0233] Since the transmission and reception period of network device 3 may be shorter during the DTX and / or DRX activation times, instructing the terminal device to camp on the first cell during the DTX and / or DRX activation times helps to improve the success rate of the terminal device camping on the first cell.

[0234] It should be noted that, since the terminal device needs to determine the start time of the system frame of network device 3 before determining the DTX and / or DRX enable times of network device 3, network device 3 can broadcast a common information block before determining the DTX and / or DRX enable times of network device 3. Correspondingly, the terminal device receives the common information block from network device 3. This allows the terminal device to determine the start time of the system frame of network device 3. Therefore, the terminal device can further determine the DTX enable time and / or DRX enable time, as well as the DTX disable time and / or DRX disable time of network device 3, based on the configuration parameters of DTX and / or DRX of network device 3.

[0235] Optionally, when the seventh information is used to indicate that the terminal device camps on the first cell during the DTX and / or DRX activation times, the terminal device may send a random access request or pilot signal to the network device 3 during the DTX and / or DRX activation times.

[0236] As an optional embodiment, the terminal device may also send uplink information to the network device 3 according to the second configuration when it is determined that the network device 3 is in an energy-saving state.

[0237] As an optional embodiment, method 500 further includes: S504, based on the first information, the terminal device sends fifth information to the network device 3, the fifth information being used to request random access to the network device 3. Correspondingly, the network device 3 receives the fifth information from the terminal device.

[0238] It should be understood that the implementation of S504 is similar to that of S303. For example, the terminal device can send the fifth information to the network device 3 according to the second configuration, as described above, and will not be repeated here.

[0239] In the above method 500, S503 can also be optional, that is, when the terminal device determines that the network device 3 is in an energy-saving state, the terminal device sends the fifth information to the network device 3 according to the second configuration. For the sake of brevity, the implementation method of this embodiment can be referred to above, and will not be repeated here.

[0240] Furthermore, in method 500, network device 2 can also be replaced by a second network device, and network device 3 can also be replaced by a first network device. This application does not specifically limit the name of the network device.

[0241] It should be understood that the order of the methods listed above does not imply the order of execution. The execution order of each process should be determined by its function and internal logic.

[0242] It should also be understood that, in the embodiments of this application, system information may also be referred to as system information block (SIB), and this application does not specifically limit it in this regard.

[0243] It should also be noted that, in the embodiments of this application, the information sent by network device 1, network device 2, and network device 3 can be information broadcast through a broadcast channel. For example, network device 1 can send public information by broadcasting public information, and network device 1 or network device 2 can send first information by broadcasting first information, etc. This application does not limit the specific method by which network device 1, network device 2, and network device 3 send information.

[0244] The information transmission method of the present application embodiments has been described in detail above with reference to Figures 3 to 5. The information transmission apparatus of the present application embodiments will be described in detail below with reference to Figures 6 and 7. The information transmission apparatus includes modules or units for executing each part of the above embodiments. The modules or units can be software, hardware, or a combination of software and hardware. The following is only a brief illustrative description of the information transmission apparatus; for details of the implementation, please refer to the description of the foregoing method embodiments, which will not be repeated below.

[0245] Figure 6 is a schematic block diagram of an information transmission device 600 provided in an embodiment of this application. As shown in Figure 6, the device 600 includes: a first transceiver module 601 and a second transceiver module 602.

[0246] In one possible implementation, the device 600 is used to perform the steps corresponding to the terminal device in the above-described method 400 or method 500.

[0247] The first transceiver module 601 is used to receive first information, which indicates that the network device 1 is in a power-saving state. The power-saving state includes the active state of discontinuous transmission (DTX) and / or the active state of discontinuous reception (DRX). The second transceiver module 602 is used to listen to public information based on the first information. The public information includes at least one of the following: system information, synchronization signal block, paging message or paging early indication.

[0248] Optionally, the first information is system information; the first transceiver module 601 is further configured to: receive second information from network device 1, the second information being used to indicate changes in system information; in response to the second information, monitor system information and receive the first information.

[0250] Optionally, the first transceiver module 601 is further configured to: receive third information from network device 1, the third information being used to indicate the first configuration.

[0251] Optionally, the first period is determined by the second period and N. The second period is the period during which public information is listened to when DTX is in a deactivated state and / or DRX is in a deactivated state. The first period is N times the second period, where N is a positive number.

[0252] Optionally, the first transceiver module 601 is further configured to: receive fourth information from network device 1, the fourth information being used to indicate the configuration parameters of DTX and / or DRX, the configuration parameters including at least one of the following: DTX period and / or DRX period, duration of DTX start time and / or duration of DRX start time, or start time interval of DTX and / or start time interval of DRX.
