Information transmission method and transmission device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 15, 2023, with application number 202311735718.0 and application name “Information Transmission Method and Transmission Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] 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

[0003] Discontinuous transmission (DTX) / discontinuous reception (DRX) technology is one of the key technologies for achieving energy conservation 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 the terminal device can transmit data during the DTX-on time / DRX-on time; and not transmit data during the DTX-off time / DRX-off time, thereby achieving energy conservation in the network device and the terminal device.

[0004] However, such information transmission method still results in poor energy-saving effects for network devices and terminal devices. Summary of the Invention

[0005] The present application provides an information transmission method and a transmission device, which can improve the energy saving effect of network equipment and terminal equipment.

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

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

[0008] It should be understood that in one case, the first network device may be network device 1 in this application, that is, network device 1 indicates to the terminal device that network device 1 is in the energy-saving state. In another case, the first network device may be network device 3 in this application, that is, network device 2 indicates to the terminal device that network device 3 is in the energy-saving state.

[0009] The information transmission method of the present application, when a network device is in an energy-saving state, broadcasts public information using a strategy that is more energy-efficient for the network device, such as broadcasting public information at a longer period, and simultaneously indicates to a terminal device that the network device is in an energy-saving state, so that the terminal device can use the corresponding strategy to monitor public information, thereby achieving better energy-saving effects for the network device and the terminal device. Furthermore, the terminal device can promptly determine changes in the state of the network device and changes in the strategy for broadcasting public information, so that the terminal device can receive public information according to the correct strategy.

[0010] In combination with the first aspect, in certain embodiments of the first aspect, the first information is system information; the method also includes: receiving second information from the first network device, the second information being used to indicate a change in the system information; receiving the first information, including: responding to the second information, monitoring the system information, and receiving the first information.

[0011] It should be understood that the second information may be, for example, a short message, in which bit 1 indicates a system information change. In response to the second information, the terminal device may re-monitor the system information and determine that the first network device is in the energy-saving state based on the system information.

[0012] In combination with the first aspect, in certain 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 the first type of public information in the public information; monitoring the remaining 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 the DRX on time; or monitoring the public information according to a fourth period or irregular time intervals during the DTX off time and / or the 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 monitor the public information using the policy corresponding to the first configuration, thereby achieving better energy-saving effects for the first network device and the terminal device.

[0013] In conjunction with the first aspect, in certain embodiments of the first aspect, the method further includes: receiving third information from the 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 public information according to the first configuration, thereby facilitating energy conservation for both the first network device and the terminal device.

[0014] In combination with the first aspect, in certain embodiments of the first aspect, the first period is determined by the second period and N, the second period is the period for monitoring public information when DTX is in a deactivated state and / or DRX is in a deactivated state, the first period is N times the second period, and N is a positive number.

[0015] It should be understood that N can also be understood as a scaling factor of 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, so that the terminal device can determine the first period based on N and the second period, which helps reduce signaling overhead.

[0016] In combination with the first aspect, in certain embodiments of the first aspect, the method further includes: receiving fourth information from the first network device, the fourth information being used to indicate configuration parameters of DTX and / or configuration parameters of DRX, the configuration parameters including at least one of the following: DTX cycle and / or DRX cycle, duration of DTX on time and / or duration of 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. This facilitates the terminal device to adopt a certain strategy to monitor public information during the DTX on time and / or DRX on time; and adopt other strategies to monitor public information during the DTX off time and / or DRX off time.

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

[0018] It should be understood that the fifth information may 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, DRX of the first network device is activated, the terminal device may use a corresponding strategy to send the fifth information, thereby helping to improve energy conservation for the terminal device and the first network device. For example, the terminal device may send the fifth information during the DRX on time.

[0019] In combination with the first aspect, in certain embodiments of the first aspect, the sending of the fifth information to the first network device includes: sending the fifth information to the first network device according to the second configuration; wherein the second configuration includes one or more of the following: sending the fifth information during the DTX on time and / or the DRX on time; or, sending the fifth information after receiving the second type of public information; or, sending the fifth information on the first time-frequency domain resource; or, sending the fifth information on the second time-frequency domain resource during the DTX off time and / or the DRX off time; or, sending the fifth information after receiving the second type of public information during the DTX off time and / or the DRX off time. 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.

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

[0021] Optionally, the method further includes: receiving information 1 from the first network device, the information 1 being used to instruct the terminal device to send uplink information in time period 1 in the DRX off time and / or time period 1 in the DTX off time. The time period 1 belongs to part of the DRX off time and / or the time period 1 belongs to part of the DTX off time. The time period 1 may be a period of time after the start of entering the DRX off time and / or the start of entering the DTX off time, for example, within 2 time slots after the start of entering the DRX off time. Alternatively, the time period 1 may 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 after 2 time slots from the moment of entering the DRX off time.

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

[0023] Optionally, the method further includes: receiving information 2 from the first network device, where the information 2 is used to indicate a DRX configuration parameter, where the DRX configuration parameter includes at least one of the following: a DRX cycle, a duration of a DRX on time, or a DRX start time interval. In this way, the terminal device can determine the DRX on time based on the DRX configuration parameter, thereby transmitting uplink information during the DRX on time, or sending uplink information during time period 1 of the DRX off time and / or time period 1 of the DTX off time.

[0024] In conjunction with the first aspect, in certain embodiments of the first aspect, the method further includes: sending sixth information to the first network device, where the sixth information is used to trigger the first network device to broadcast at least one type of public information. In this way, if the terminal device does not need to receive the at least one type of public information, the first network device may not send the at least one type of public information; if the terminal device does need to receive the at least one type of public information, the first network device sends the at least one type of public information based on the sixth information.

[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 unidirectional control channel that can broadcast public information about the cell. It consists of a frequency correction channel (FCCH), a synchronization channel (SCH), and a broadcast control channel (BCCH).

[0081] 3. Paging messages (paging), which may include short message type paging messages and paging terminal type paging messages.

[0082] Among them, short message-type paging messages can, for example, indicate system information updates, earthquake and tsunami warnings, etc. For short message-type messages, terminal devices in the radio resource control (RRC) idle state, inactive state, and RRC connected state all need to receive them. Paging terminal-type paging messages can include multiple paging UE IDs. When a terminal device determines that there is a paging UE ID that is the same as its own paging UE ID among the multiple paging UE IDs in the paging message, it can determine that the network device has paged the terminal device, and then access the network device through processes such as random access. For paging terminal-type paging messages, 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.

[0083] 4. Short message paging message, also known as short message. It may include 8 bits, each of which may be used to indicate different information. For example, bit 1 indicates whether the system information has changed (e.g., bit 1 is 1, indicating a system information change); bit 2 indicates an earthquake or typhoon warning notification (e.g., bit 2 is 1, indicating an earthquake or typhoon warning); bit 3 indicates whether paging monitoring is stopped (e.g., bit 3 is 1, indicating stopping monitoring of PDCCH paging in this paging opportunity, etc.). Other bits may be reserved.

[0084] 5. Paging early indication (PEI): information used to instruct terminal devices to monitor paging messages.

[0085] It should be understood that if the PEI indicates that the paging message needs to be received in the paging occasion, then the terminal device needs to receive the paging message in the corresponding paging occasion; if the PEI indicates that the paging message does not need to be monitored in the paging occasion, then the terminal device does not need to monitor the paging message in the paging occasion.

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

[0087] A network device can activate or deactivate DTX / DRX, meaning that DTX / DRX can be in an active or deactivated state. The active state of DTX / DRX can refer to the use of DTX / DRX technology for communication between the network device and the terminal device. Correspondingly, the deactivated state of DTX / DRX can refer to the non-use of DTX / DRX technology for communication between the network device and the terminal device.

[0088] When DTX / DRX is in an activated state, the network device and the terminal device can perform data transmission during the DTX on time (DTX on time) / DRX on time (DRX on time); and no data transmission is performed during the DTX off time (DTX off time) / DRX off time (DRX off time).

[0089] For example, FIG1 is a schematic diagram of a DTX activated state (or DRX activated state). When DTX is activated, the DTX on-time (or DRX on-time) may be indicated by the raised portion in FIG1 , and the DTX off-time (or DRX off-time) may be indicated by the recessed portion in FIG1 . A DTX cycle (or DRX cycle) may refer to the time interval between two adjacent moments of the start of the DTX on-time (or DRX on-time), or the time interval between two adjacent moments of the start of the DTX off-time (or DRX off-time).

[0090] During the DTX on time, the network device can send downlink information, and correspondingly, the terminal device can monitor / receive downlink information from the network device; during the DTX off time, the network device does not send downlink data, and the terminal device may not monitor downlink information from the network device. Similarly, when DRX is activated, during the DRX on time, the terminal device can send uplink information to the network device, and correspondingly, the network device can monitor / receive uplink data from the network device; during the DRX off time, the terminal device does not send uplink information to the network device, and correspondingly, the network device does not monitor / receive uplink data sent from the terminal device. In this way, during the DRX off time and / or the DTX off time, the power consumption of the network device and the terminal device is low. Therefore, when DTX / DRX is in the activated state, it can be considered that the network device is in an energy-saving state.

[0091] It should be understood that in the embodiments of the present application, the activation state and the deactivation state are examples used to describe whether the DTX / DRX technology is in use. The activation state can also be referred to as the enabled state, and the deactivation 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, DTX on time / DRX on time can also be referred to as DTX activation time / DRX activation time, and DTX off time / DRX off time can also be referred to as DTX deactivation time / DRX deactivation time. This application does not specifically limit this.

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

[0093] FIG2 is a schematic diagram of a communication system 200 used in an embodiment of the present application. The communication system 200 may include at least one network device, such as the network device 210 shown in FIG2 ; the communication system 200 may also include at least one terminal device, such as the terminal device 220 shown in FIG2 . The network device 210 and the terminal device 220 may communicate via a wireless link. In one possible scenario, the network device 210 may act as a transmitter, the terminal device 220 may act as a receiver, and the network device 210 may send a signal to the terminal device 220; in another possible scenario, the network device 210 may act as a receiver, the terminal device 220 may act as a transmitter, and the terminal device 220 may send a signal to the network device 210.

[0094] Figure 2 exemplarily shows a network device 210 and a terminal device 220. Optionally, the communication system 200 may also 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., which is not limited in this embodiment of the present application.

[0095] Each of the above-mentioned communication devices, such as the network device 210 or the terminal device 220 in Figure 2, can be configured with multiple antennas. The multiple antennas may include at least one transmitting antenna for sending signals and at least one receiving antenna for receiving signals. In addition, each communication device also includes a transmitter chain and a receiver chain. Those skilled in the art will understand that they may include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, demodulators, demultiplexers, or antennas, etc.). Therefore, the network device 210 and the terminal device 220 can communicate using multi-antenna technology.

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

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

[0098] Currently, when DTX / DRX is active, network devices broadcast public information, such as system information and paging messages, using the same periodicity, regardless of whether they are in DTX-on time / DRX-on time, DRX-off time, or / and DTX-off time. Correspondingly, terminal devices also need to monitor the public information broadcast by network devices using the same periodicity. This information transmission method results in poor energy conservation for both network devices and terminal devices.

[0099] To address the above technical issues, the present application provides an information transmission method. When DTX / DRX is activated, a network device can employ a specific strategy to broadcast public information, such as using a longer period than when DTX / DRX is deactivated, thereby achieving better energy conservation for the network device. Furthermore, when DTX / DRX is activated, the network device can instruct a terminal device to be in an energy-saving state, allowing the terminal device to monitor public information according to the corresponding strategy. This reduces the number of times the terminal device monitors public information, resulting in better energy conservation for the terminal device.

[0100] The information transmission method of the present application is 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 quantity of each device shown therein are only examples and should not constitute any limitation on the implementation of the method provided by this application. Below, the information transmission method of the embodiment of this application is described in detail, taking the terminal device and network device as the execution entities as an example.

[0101] It should be understood that the terminal device can be the terminal device itself, or it can be a chip, chip system or processor that supports the terminal device to implement the data transmission method, or it can 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, or it can be a chip, chip system or processor that supports the network device to implement the data transmission method, or it can 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.

[0102] FIG3 is a flow chart illustrating an information transmission method 300 provided in an embodiment of the present application. Method 300 can be applied to a system including a terminal device and a network device, such as system 200. The network device can be, for example, network device 1 shown in FIG3 . The terminal device can be in an idle or inactive state.

[0103] The method 300 includes the following steps:

[0104] S301: Network device 1 sends first information. Correspondingly, a terminal device receives the first information. The first information is used to indicate that network device 1 is in an energy-saving state, where the energy-saving state includes DTX being activated and / or DRX being activated.

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

[0106] It should be noted that DTX being in an activated state and / or DRX being in an activated state are both energy-saving states. The embodiment of the present application can be applicable to the case where the network device 1 DTX is in an activated state and / or the network device 1 DRX is in an activated state, and the present application does not make specific limitations on this.

[0107] Optionally, the first information may be carried in a short message, for example, bit 4, bit 5, or bit 6 in the short message. Assuming 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 the network device 1 is in an energy-saving state.

[0108] S302: Network device 1 sends public information. Correspondingly, the terminal device monitors 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.

[0109] It should be understood that the random access time-frequency domain resource information may be information for indicating random access time-frequency domain resources, and the random access pilot information may be information for indicating random access pilots. The random access time-frequency domain resource information and the random access pilot may be carried in one signaling and sent, or may be carried in different signaling and sent. The strategy adopted by the network device 1 for sending public information may be different from the strategy adopted for sending public information when DTX is in a deactivated state and / or DRX is in a deactivated state. Moreover, compared with the strategy adopted for sending public information when DTX is in a deactivated state and / or DRX is in a deactivated state, the strategy adopted by the network device 1 for sending public information when DTX is in an activated state and / or DRX is in an activated 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 in an activated state, the strategy adopted by the subsequent network device 1 to send public information may be related to the configuration parameters of DTX; if the DRX of network device 1 is in an activated state, the strategy adopted by the subsequent network device 1 to send public information may be related to the configuration parameters of DRX; if the DRX of network device 1 is in an activated state and the DTX is in an activated state, the strategy adopted by the subsequent 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 any specific restrictions on this.

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

[0112] The information transmission method of the present application, when a network device is in an energy-saving state, broadcasts public information using a strategy that is more energy-efficient for the network device, such as broadcasting public information at a longer period, and simultaneously indicates to a terminal device that the network device is in an energy-saving state, so that the terminal device can use the corresponding strategy to monitor public information, thereby achieving better energy-saving effects for the network device and the terminal device. Furthermore, the terminal device can promptly determine changes in the state of the network device and changes in the strategy for broadcasting public information, so that the terminal device can receive public information according to the correct strategy.

[0113] As an optional embodiment, the first information may be system information, and method 300 further includes: network device 1 sends second information to the terminal device, where the second information is used to indicate a change in system information; S301 may 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 information may be, for example, a short message, in which bit 1 indicates a system information change. In response to the second information, the terminal device may re-monitor the system information and determine that the network device 1 is in the energy-saving state based on the system information.

[0115] It should be understood that, in addition to the system information, the first information may also be carried in a downlink message sent via the PDCCH, and this application does not impose any specific limitation on this.

[0116] The following describes the strategy for network device 1 to send public information and the strategy for terminal devices to monitor public information when network device 1 is in the energy-saving state. This strategy can be divided into two cases. In one case, the strategy can be implemented without being based on DTX configuration parameters and / or DRX configuration parameters, such as the first configurations 1 to 7 described below. In the other case, the strategy is implemented based on DTX configuration parameters and / or DRX configuration parameters, such as the first configurations 8 to 10 described below.

[0117] As an optional embodiment, S302 can be implemented in the following manner: the network device 1 adopts the first configuration to send public information. Correspondingly, the terminal device adopts the first configuration to listen to and receive public information. 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 early paging indication; during the DTX on time and / or the DRX on time, the network device 1 sends public information according to the third period, and correspondingly, the terminal device listens to the public information according to the third period; or, during the DTX off time and / or the DRX off time, the network device 1 sends public information according to the fourth period or irregular time intervals, and correspondingly, the terminal device listens to the public information according to the fourth period or irregular time intervals.

[0118] The first configuration may be understood as a policy for the network device 1 to send public information or a policy for the terminal device to monitor public information.

[0119] The first type, the first configuration is the first cycle.

[0120] The first period is a positive number. The first period may be greater than the period used to broadcast public information when the network device 1 is in a non-energy-saving state. For example, if the period used to broadcast public information when the network device 1 is in a non-energy-saving state is 10 ms, the first period may be 15 ms, 30 ms, or the like.

[0121] In this way, the network device 1 can broadcast public information at a larger period, and the terminal device can monitor public information at a larger period, so that the energy saving effect of the network device 1 and the terminal device is better.

[0122] The second, first configuration 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 types of public information, such as system information, synchronization signal blocks, paging messages, or random access messages. The random access message may 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 monitor the first type of public information in the public information.

[0123] In this way, the network device 1 may not send the first type of public information, and the terminal device may not monitor the first type of public information, so that the energy saving effect of the network device 1 and the terminal device is better.

[0124] The third type is to send other types of public information after sending the early paging indication. Other types of public information are information in the public information other than the early paging indication. For example, paging messages, system information, etc. Correspondingly, for the terminal device, the first configuration is to monitor other types of public information after monitoring the early paging indication.

[0125] In this way, the terminal device may not monitor other types of public information before monitoring the early paging indication, and may monitor other types of public information after receiving the early paging indication, thereby achieving better energy saving effect of the terminal device.

[0126] Optionally, the early paging indication may carry information for instructing monitoring of other types of public information. Exemplarily, the early paging indication carries information for instructing monitoring of paging messages or public information. For example, the early paging indication indicates monitoring of paging messages or public information through bit 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.

[0127] In this way, the terminal device may not monitor other types of public information before monitoring the early paging indication. After receiving the early paging indication, it may monitor other types of public information according to the information carried in the early paging indication for indicating monitoring of other types of public information, thereby achieving better energy-saving effect for the terminal device.

[0128] Optionally, the network device 1 sends to the terminal device public information indicating other types of information. The public information indicating other types of information may be, for example, bit information, where the bit information being 11 may indicate monitoring of public information, the bit information being 00 may indicate monitoring of paging messages, the bit information being 10 may indicate monitoring of public information and paging messages, and the like.

[0129] It should be understood that the common information indicating other types and the early paging indication may be sent through the same signaling or different signaling, and this application does not make any specific limitation on this.

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

[0131] The fourth type, the first configuration, is the first period and not sending the first type of public information in the public information, that is, the network device 1 does not send the first type of public information, but sends other types of public information in the first period.

[0132] In this way, the network device 1 can broadcast public information at a larger period, the terminal device can monitor public information at a larger period, and the network device 1 may not send the first type of public information, and the terminal device may not monitor the first type of public information, so that the energy saving effect of the network device 1 and the terminal device is better.

[0133] The fifth and first configurations are: the first cycle and sending the remaining types of public information after sending the early paging indication. That is, the terminal device monitors the remaining types of public information after monitoring the early paging indication. Furthermore, the network device 1 uses the first cycle to send the early paging indication and / or the remaining types of public information, and the terminal device uses the first cycle to monitor the early paging indication and / or the remaining types of public information.

[0134] In this way, the network device 1 can broadcast public information at a larger period, the terminal device can monitor public information at a larger period, and the terminal device may not monitor other types of public information before monitoring the early paging indication, thereby achieving better energy saving effects for the network device 1 and the terminal device.

[0135] The sixth type, the first configuration is not to 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, the network device 1 may not send the first type of public information, the terminal device may not monitor the first type of public information, and the terminal device may not monitor the remaining types of public information before monitoring the early paging indication, so that the network device 1 and the terminal device have better energy saving effects.

[0137] The seventh type, the first configuration is the first period, the first type of public information in the public information is not sent, and the remaining types of public information are sent after the paging early indication is sent.

[0138] In this way, the network device 1 can broadcast public information at a larger period, and the terminal device can monitor public information at a larger period; the network device 1 may not send the first type of public information, and the terminal device may not monitor the first type of public information; and the terminal device may not monitor other types of public information before monitoring the early indication of paging, so that the energy saving effect of the network device 1 and the terminal device is better.

[0139] The eighth type, the first configuration is that during the DTX on time and / or the DRX on time, the network device 1 sends public information according to the third period, and correspondingly, the terminal device listens to the public information according to the third period; and / or, during the DTX off time and / or the DRX off time, the network device 1 sends public information according to the fourth period or irregular time intervals, and correspondingly, the terminal device listens to the public information according to the fourth period or irregular time intervals.

[0140] The third period may be the same as the second period, that is, the third period is the period for monitoring public information when DTX is in a deactivated state and / or DRX is in a deactivated state, and the third period may also be different from the second period. The fourth period may be different from the third period, and the fourth period may be greater than the third period, for example, the third period is 10ms and the fourth period is 30ms. Alternatively, the fourth period may be M times the third period, where M is a positive integer. Exemplarily, as shown in FIG4 , M is 2, and the moment when the network device 1 sends public information or the terminal device monitors public information may be the moment indicated by the solid arrow in FIG4 . At the moment indicated by the dotted arrow, the network device 1 does not send public information, and the terminal device does not monitor public information.

[0141] Irregular time intervals can be understood as multiple time intervals during which network device 1 sends public information that are not identical within a DTX-off period (or DRX-off period), i.e., multiple time intervals during which a terminal device monitors public information that are not identical. Each of the 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 off time (or DRX off time), the second time interval for network device 1 to send public information is twice the first time interval for sending public information, the third time interval for sending public information is three times the first time interval for sending public information, the fourth time interval for sending public information is four times the first time interval for sending public information, and so on. The first time interval for network device 1 to send public information can be understood as the time interval between the moment when network device 1 sends public information for the first time and the moment when it sends public information for the second time after entering the DTX off time (or DRX off time). 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 moment when network device 1 sends public information for the second time and the moment when it sends public information for the third time, and so on.

[0143] In the second example, within a DTX-off period (or DRX-off period), the second time interval for network device 1 to send public information is 1 / 2 of the first time interval for sending public information, the third time interval for sending public information is 1 / 3 times the first time interval for sending public information, the fourth time interval for sending public information is 1 / 4 times the first time interval for sending public information, and so on. 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, and can be found in the description above, and are not repeated here.

[0144] 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 a protocol or indicated by the network device 1 through signaling.

[0145] The 9th type, the first configuration is that during the DTX on time and / or the DRX on time, the network device 1 sends public information according to the third period, and correspondingly, the terminal device monitors the public information according to the third period; and / or, during the DTX off time and / or the DRX off time, the network device 1 does not send the first type of public information in the public information and / or sends the remaining types of public information after sending the early paging indication, and correspondingly, the terminal device does not monitor the first type of public information in the public information and / or monitors the remaining types of public information after monitoring the early paging indication.

[0146] It should be understood that the third cycle can be the same as or different from the second cycle. The instructions for not sending the first type of public information in the public information and / or sending the remaining types of public information after sending the paging early indication can be found in the above description and will not be repeated here.

[0147] The tenth type, the first configuration is that during the DTX on time and / or the DRX on time, the network device 1 does not send the first type of public information in the public information, and correspondingly, the terminal device does not monitor the first type of public information in the public information; and / or, during the DTX off time and / or the DRX off time, the network device 1 sends the remaining types of public information after sending the early paging indication, and correspondingly, the terminal device monitors the remaining types of public information after monitoring the early paging indication.

[0148] It should be understood that in this embodiment, the strategy of network device 1 sending public information during DTX on time and / or DRX on time and the strategy of network device 1 sending public information during DTX off time and / or DRX off time can also be interchanged. For the sake of simplicity, they are not repeated here.

[0149] It should be noted that the several strategies included in the first configuration can also be arranged and combined in a manner 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 embodiment, the first configuration may be agreed upon by a protocol or configured by the network device 1 through signaling.

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

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

[0153] 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 public information according to the first configuration, which helps save energy for the network device 1 and the terminal device.

[0154] Optionally, the third information and / or the first information may be carried in the system information. Alternatively, the third information may be carried in an RRC release message. The third information may be configured when the 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 period. For example, the third information includes 20, which means the first period is 20ms.

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

[0158] 3. The third information includes information indicating N, or the third information includes information indicating N and a second period. The second period is a period for monitoring common information 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.

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

[0160] In this way, the terminal device can determine the first period according to the second period and N.

[0161] When the third information includes N, the terminal device may already know the second period. For example, the second period is agreed upon by the protocol, or the terminal device may monitor public information using the second period before receiving the first information. This eliminates the need for network device 1 to indicate the second period, reducing signaling overhead. 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 indicating N may be N itself or a second preset identifier, such as 10, 01, or 00. 10 may indicate that N is 2, 01 may indicate that N is 4, or 00 may indicate that N is 6.

[0163] It should be noted that the number of the first period can be multiple, for example, the first period can include the period of system information, the period of synchronization information block and the period of paging message, etc. Correspondingly, the number of N can also be multiple, for example, N includes the period scaling factor corresponding to the system information, the period scaling factor of the paging message, etc. This application does not make specific restrictions on this.

[0164] In one example, the first information is system information, which is different from the system information sent by network device 1 when DTX is in an inactive state and DRX is in an inactive state. The first information is further configured with a first period, and the first period includes: a sending period of a synchronization information block: for example, ssb-periodicity serving cell-nes ms40; a sending period of a paging message: for example, paging cycle-nes rf64; and a sending period of system information, for example, si-periodicity-nes rf64. Among them, ssb-periodicity serving cell-nes ms40 indicates that the sending period of the synchronization information block additionally configured in the system information is 40ms; paging cycle-nes rf64 indicates that the sending period of the paging message additionally configured in the system information is 64 radio frames (RF); and si-periodicity-nes rf64 indicates that the sending period of the system information additionally configured in the system information is 64RF.

[0165] In another example, the first information is system information, which is different from the system information sent by network device 1 when DTX and DRX are inactive. The first information also includes an additional N. For example, the system information sent by network device 1 when DTX and DRX are inactive includes the synchronization information block transmission period, such as ssb-periodicity serving cell ms10, and the paging message transmission period, such as paging cycle rf32. The first information includes not only the synchronization information block transmission period and the paging message transmission period, but also a scaling factor of 4 for the synchronization information block transmission period and a paging message transmission period of 2. 4 and 2 can be understood as the aforementioned N.

[0166] Optionally, method 300 further includes: network device 1 sending information indicating the first period to the terminal device. Correspondingly, the terminal device receives the 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 found in the manner in which the third information indicates the first period, and is not further described here.

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

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

[0169] The third information includes information for indicating 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 the network device 1 does not send a synchronization information block based on #SSB; 0011 can represent system information, and the terminal device can determine that the network device 1 does not send system information based on 0011.

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

[0171] Optionally, method 300 further includes: network device 1 sending information indicating the first type of public information to the terminal device. Correspondingly, the terminal device receives the 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 found in the manner in which the third information indicates the first type of public information, and is not further described here.

[0172] It should be understood that the information used to indicate the first type of public information and the third information may be sent through the same signaling or different signaling, and when the information used to indicate the first type of public information and the third information are sent through the same signaling, the information used to indicate the first type of public information and the third information may be carried in the same or different fields, or the information used to indicate the first type of public information and the third information may be carried in the same or different information elements, and this application does not specifically limit this. In addition, the third period, and / or the fourth period or the irregular time interval may be indicated in the following manner.

[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 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 indicating the third period and / or the fourth period or the irregular time interval from network device 1.

[0174] 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.

[0175] The information indicating the third period can be the third period itself, such as 10, where 10 indicates that the third period is 10 ms. The information indicating the third period can also be a fourth preset identifier, such as 001, where 001 indicates that the third period is 10 ms. The fourth period is indicated in a similar manner to the third period and will not be described in detail here. The information indicating the irregular time interval can be a fifth preset identifier, such as #1, where #1 indicates that the irregular time interval is the time interval described in the first example above.

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

[0177] 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 signaling. In the case where 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 information elements 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 any specific restrictions on this.

[0178] In another possible embodiment, the third period and / or the fourth period or the irregular time interval are agreed upon by the protocol. Thus, after the terminal device determines the DTX on time (or DRX on time) and the DTX off time (or DRX off time), it can determine a strategy for monitoring public information based on the third period and / or the fourth period or the irregular time interval. This eliminates the need for the network device 1 to indicate the third period and / or the fourth period or the irregular time interval, resulting in reduced signaling overhead.

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

[0180] In this way, when the terminal device determines that the network device 1 is in the energy-saving state, it can use the first configuration to monitor public information by itself, without the network device 1 indicating the first configuration through signaling, so that the signaling overhead is small.

[0181] Based on the above embodiments, as an optional embodiment, method 300 also includes: the network device 1 sends fourth information to the terminal device, 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: DTX cycle and / or DRX cycle, the duration of the DTX on time and / or the duration of the DRX on time, or the start time interval of DTX and / or the start time interval of DRX.

[0182] It should be understood that the fourth information and the first information may be sent via the same signaling or via different signaling. When the fourth information and the first information are sent via the same signaling, the fourth information and the first information may be carried in the same or different information elements 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 impose specific limitations on this.

[0183] When DTX is in an activated 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 an activated 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 an activated state and DRX is in an activated 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 cycle, the duration of the DTX on time, or the starting time interval of DTX. The configuration parameters of DRX include at least one of the following: DRX cycle, the duration of the DRX on time, or the starting time interval of DRX.

[0184] The duration of the DTX on time (or the duration of the DRX on time) may refer to the duration of a period of DTX on time (DRX on time), such as the duration represented by a bulge in FIG1 .

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

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

[0187] Through the configuration parameters of DTX and / or DRX, 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. This makes it easier for the terminal device to use certain strategies to monitor public information during the DTX on time and / or DRX on time; and use other strategies to monitor public information during the DTX off time and / or DRX off time, without affecting the terminal device's normal monitoring of the public information sent by the network device 1. For example, the network device 1 can send public information according to the above-mentioned 8th to 10th first configurations; correspondingly, after the terminal device determines the DTX on time and / or DRX on time, as well as the DTX off time and / or DRX off time, it can monitor the public information from the network device 1 according to the above-mentioned 8th to 10th first configurations. In this way, the terminal device can

[0188] As an optional embodiment, method 300 also includes: sending sixth information to network device 1, the sixth information is used to trigger network device 1 to broadcast at least one public information; network device 1 receives the sixth information from the terminal device, and sends at least one public information in response to the sixth information; the terminal device receives at least one public information.

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

[0190] In a possible implementation manner, the sixth information is sent in the first time period.

[0191] The first time period may be determined by the following methods: the start time of the first time period and the duration of the first time period, or the start time and end time of the first time period.

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

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

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

[0196] In addition to the network device 1 sending public information according to the first configuration, the terminal device correspondingly monitors the 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 the network device 1 is in the energy-saving state.

[0197] As an optional embodiment, the method 300 further includes: S303: based on the first information, the terminal device sends fifth information to the network device 1, where the fifth information is 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 information may be, for example, a random access request, a random access signal, etc. The fifth information may be used to randomly access network device 1. When the terminal device determines that the first network device is in an energy-saving state, for example, when DRX is activated on the first network device, the terminal device may use a corresponding strategy to send the fifth information, thereby improving energy conservation for both the terminal device and the first network device. For example, the terminal device may send the fifth information during DRX activation time.

[0199] In one possible implementation, 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: the terminal device sends the fifth information to the network device 1 during the DTX on time and / or the DRX on time; sends the fifth information after receiving the second type of public information, where the second type of public information may be, for example, an early paging indication; sends the fifth information on a first time-frequency domain resource; sends the fifth information on a second time-frequency domain resource during the DTX off time and / or the DRX off time; or sends the fifth information after receiving the second type of public information during the DTX off time and / or the DRX off time.

[0200] 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 the DRX-on time; receiving the fifth information after sending the second type of public information, where the second type of public information may be, for example, an early paging indication; receiving the fifth information on a first time-frequency domain resource; receiving the fifth information on a second time-frequency domain resource during the DTX-off time and / or the DRX-off time; or receiving the fifth information after sending the second type of public information during the DTX-off time and / or the DRX-off time.

[0201] Among them, the first time-frequency domain resources and / or the second time-frequency domain resources can be configured by the network device 1 through signaling, agreed upon by protocol or preset. Sending the fifth information on the second time-frequency domain resources during the DTX off time and / or the DRX off time can be understood as, if the terminal device sends the fifth information to the network device 1 during the DTX off time and / or the DRX off time, it is necessary to use the second time-frequency domain resources. Sending the fifth information after receiving the second type of public information during the DTX off time and / or the DRX off time can be understood as, if the terminal device sends the fifth information to the network device 1 during the DTX off time and / or the DRX off time, it is necessary to send the fifth information after receiving the second type of public information.

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

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

[0204] The second configuration may be configured by the network device 1 through signaling or agreed upon by a protocol, as follows.

[0205] Optionally, method 300 further includes: network device 1 sending information 3 to the terminal device, where information 3 is used to indicate the second configuration. Correspondingly, the terminal device receives information 3 from network device 1. In this way, network device 1 can indicate to the terminal device when to send the fifth information, thereby improving the success rate of the terminal device accessing network device 1 and further improving energy conservation for the network device and the terminal device.

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

[0207] Optionally, method 300 also includes: receiving information 1 from the first network device 1, information 1 is used to instruct the terminal device to send uplink information in time period 1 in the DRX off time and / or time period 1 in the DTX off time. The time period 1 belongs to part of the DRX off time and / or the time period 1 belongs to part of the DTX off time. The time period 1 can be a period of time after the start of entering the DRX off time and / or the start of entering the DTX off time, for example, within 2 time slots after the start of entering the DRX off time. Alternatively, the 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 after 2 time slots from the moment of entering the DRX off time.

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

[0209] It should be understood that information 1 and information 3 may be sent via the same signaling or different signaling. If information 1 and information 3 are sent via the same signaling, they may be sent via the same field or different fields; and they may also be sent via the same cell or different cells, which is not specifically limited in this application.

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

[0211] In the above method 300, S302 may also be optional, 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 brevity, the implementation of this embodiment can be found above and will not be repeated here.

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

[0213] In order to facilitate terminal equipment to access a cell served by a network device in an energy-saving state, the present application also provides an information transmission method, which is described as follows.

[0214] Figure 5 is a flow chart illustrating an information transmission method 500 provided in an embodiment of the present 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 shown in Figure 5. The terminal device may be in an idle or inactive state.

[0215] The method 500 includes the following steps:

[0216] S501: Network device 3 sends eighth information to network device 2. The eighth information is used to indicate that network device 3 is in an energy-saving state and / or DTX configuration parameters and / or DRX configuration parameters of network device 3. The configuration parameters include at least one of the following: a DTX cycle and / or a DRX cycle, a DTX on-time duration and / or a DRX on-time duration, or a DTX start time interval and / or a DRX start time interval. The energy-saving state includes DTX being in an active state and / or DRX being in an active state. Correspondingly, network device 2 receives the eighth information from network device 3.

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

[0218] S502: Network device 2 sends first information, where the first information is used to indicate that network device 3 is in an energy-saving state. Correspondingly, the terminal device receives the first information.

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

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

[0221] It should be understood that the public information may indicate a synchronization information block, etc. The public information may be described in the method 300 and will not be described in detail here.

[0222] Network device 2 indicates to the terminal device that network device 3 is in energy-saving state. In this way, the terminal device can adopt corresponding strategies to monitor the public information sent by network device 3, which helps the terminal device to accurately obtain public information such as synchronization information blocks from network device 3, thereby helping the terminal device to access the cell served by network device 3.

[0223] As an optional embodiment, method 500 further includes: network device 2 sending seventh information to the terminal device, and correspondingly, the terminal device receiving the seventh information from network device 2. The seventh information is used to indicate one or more of the following: an updated priority of the first cell, the updated priority being lower than the original priority of the first cell, and the first cell being a cell served by network device 3; or, using the fifth period to monitor synchronization signal blocks from network device 3; or, DTX configuration parameters and / or DRX configuration parameters of network device 3; or, residing in the first cell during the DTX on time and / or the DRX on time.

[0224] 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, the terminal device is less likely to select the first cell due to the lower updated priority of the first cell. The seventh information can be a sixth preset identifier, such as 02, which can indicate that the priority of the first cell is adjusted from the first level to the third level, or that the priority of the first cell is reduced by two levels, etc.

[0225] Assuming that when network device 3 is not in the energy-saving state, the period for the terminal device to monitor 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 monitor the synchronization information block with a larger period. In this way, the terminal device can take a longer time to search for the synchronization information block, which helps the terminal device to reside in network device 3.

[0226] It should be understood that the manner in which the seventh information indicates the fifth cycle can refer to the manner in which the third cycle is indicated in method 300, and will not be described in detail here.

[0227] It should be noted that network device 3 may also send public information according to the first configuration in method 300; correspondingly, the terminal device monitors public information from network device 3 according to the first configuration. The first configuration may be configured by network device 2 through signaling or by a protocol agreement. The specific content of the first configuration and the manner in which network device 2 configures the first configuration through signaling can be found in the description of method 300 and 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 information indicating the seventh information and / or the first configuration from network device 3. In this way, network device 2 can determine information such as DTX configuration parameters and / or DRX configuration parameters of network device 3, the first configuration, etc., so that network device 2 can 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 one signaling or through different signaling, and in the case where the information used to indicate the seventh information and / or the first configuration and the eighth information are sent through one signaling, the information used to indicate the seventh information and / or the first configuration and the eighth information can be carried in the same or different fields of the signaling, or the information used to indicate the seventh information and / or the first configuration and the eighth information can be carried in the same or different elements of the signaling. This application does not make any specific limitations on this.

[0230] Optionally, the seventh information and / or the first configuration may also be agreed upon in a protocol. In this way, after receiving the eighth information, the network device 2 may determine the DTX configuration parameters and / or DRX configuration parameters of the network device 3, the first configuration, and other information, thereby directly indicating the first configuration and / or the seventh information to the terminal device.

[0231] In addition, 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 through the DTX configuration parameters and / or DRX configuration parameters of the network device 3.

[0232] Since network device 2 instructs the terminal device to reside in the first cell during the DTX on time and / or the DRX on time, the terminal device needs to determine the DTX on time and / or the DRX on time, as well as the DTX off time and / or the DRX off time of network device 3. Therefore, the seventh information may include the DTX configuration parameters and / or the DRX configuration parameters of network device 3, and reside in the first cell during the DTX on time and / or the DRX on time. Optionally, the DTX configuration parameters and / or the DRX configuration parameters of network device 3, and reside in the first cell during the DTX on time and / or the DRX on time can also be indicated by different signaling. For example, the eighth information indicates to reside in the first cell during the DTX on time and / or the DRX on time; then network device 2 also sends information 4 to the terminal device, and information 4 is used to indicate the DTX configuration parameters and / or the DRX configuration parameters of network device 3. Information 4 and the seventh information can be indicated by different signaling.

[0233] Since the period of sending and receiving information of network device 3 may be smaller during the DTX on time and / or the DRX on time, instructing the terminal device to reside in the first cell during the DTX on time and / or the DRX on time helps to improve the success rate of the terminal device residing in the first cell.

[0234] It should be noted that, since the terminal device needs to first determine the start time of the system frame of network device 3 in order to determine the DTX on time and / or DRX on time of network device 3, before the terminal device determines the DTX on time and / or DRX on time of network device 3, network device 3 may broadcast a common information block, and correspondingly, the terminal device receives the common information block from network device 3. In this way, the terminal device can determine the start time of the system frame of network device 3. The terminal device can then further determine the DTX on time and / or DRX on time, as well as the DTX off time and / or DRX off time of network device 3 based on the DTX configuration parameters and / or DRX configuration parameters of network device 3.

[0235] Optionally, when the seventh information is used to indicate staying in the first cell at the DTX on time and / or the DRX on time, the terminal device can send a random access request or a pilot signal, etc. to the network device 3 at the DTX on time and / or the DRX on time.

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

[0237] As an optional embodiment, the method 500 further includes: S504: based on the first information, the terminal device sends fifth information to the network device 3, where the fifth information is 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 the implementation of S303. For example, the terminal device can send the fifth information to the network device 3 according to the second configuration. Please refer to the above description and will not be repeated here.

[0239] In the above method 500, S503 may also be optional, that is, when the terminal device determines that the network device 3 is in the energy-saving state, the terminal device sends the fifth information to the network device 3 according to the second configuration.
