Description

Instruction information communication method and device

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on September 30, 2018, with an application number of 2018111631960, and an application name of "Indicating Information and Communication Methods and Devices", the entire contents of which are incorporated herein by reference.

Technical field

The present application relates to communication technologies, and in particular, to a method and device for communicating instruction information.

Background technique

Discontinuous reception (DRX) is a technology used to reduce power consumption of terminal equipment in long term evolution (LTE) communications. DRX technology allows terminal equipment to enter the dormant state at certain times in each DRX cycle and does not monitor the physical downlink shared channel (PDCCH); and enters the activation when the DRX cycle needs to be monitored at certain times Status to listen to the PDCCH. Therefore, the terminal device will not be in the state of monitoring the PDCCH all the time, and the purpose of saving the power consumption of the terminal device and improving the endurance can be achieved, so as to improve the user experience of the terminal device.

In a new radio (NR) system, because the proportion of high-speed data transmission services increases and the maximum rate increases significantly, the data communicated between terminal equipment and network equipment may be generated in bursts and completed in a short time. . In order to further improve the performance of terminal equipment, NR also provides a mechanism for indicating information based on DRX (such as: wakeup signal (WUS) and go-to-sleep signal (GTS)) to further Save power consumption of terminal equipment. In the WUS mechanism, if the terminal equipment receives the WUS signal corresponding to the DRX cycle, it will be activated in the DRX cycle and monitor the PDCCH or receive the physical downlink shared channel. , PDSCH); If the terminal device does not receive the WUS signal corresponding to the DRX cycle, it does not monitor the PDCCH or receive the PDSCH during the DRX cycle. However, in the GTS mechanism, the terminal device receives the GTS corresponding to the DRX. Signal, it is in a sleep state in the DRX cycle and does not monitor the PDCCH or receive PDSCH; if the terminal device does not receive a WUS signal corresponding to the DRX cycle, it is in an active state in the DRX cycle and monitors the PDCCH or receives PDSCH.

The terminal device with more services in the NR system is more suitable for the GTS mechanism. It is required that the terminal is always in the activated state. Only when the service ends, the GTS signal can be used for sleep. The terminal device with fewer services is more suitable for the WUS mechanism and requires the terminal. The device is often in a sleep state and only wakes up through a WUS signal when it needs to process services. However, in the prior art, only one of the WUS signal and the GTS signal can be used as a power saving application in all terminal devices of the NR system. The NR system cannot dynamically determine more suitable indication information for different terminal devices. In this way, if the terminal device configured with the WUS mechanism has frequent services, an additional WUS instruction message needs to be received and processed before each DRX cycle, which not only does not save the power consumption of the terminal device, but also performs the instruction information frequently. Reception and processing increase the power consumption of the terminal equipment. However, if the terminal device configured with the GTS mechanism is infrequent, the terminal device in the sleep mode before each DRX cycle needs to receive and process a GTS indication message, and the power saving of the terminal device is also limited. Therefore, how to overcome the aforementioned problems brought about by the use of a single type of instruction information is a technical problem to be solved urgently at present.

As another example, in a time division duplex (TDD) system and a full duplex (TDD) system, the forward link and the reverse link may use a common frequency band.

Each antenna (or antenna group consisting of multiple antennas) and / or area designed for communication is called a sector of the network device 11.

For example, the antenna group may be designed to communicate with a communication device in a sector covered by the network device 11. The network device 11 may send signals to all communication devices in its corresponding sector through a single antenna or multiple antenna transmit diversity. In the process that the network device 11 communicates with the communication device 21 through the forward link, the transmitting antenna of the network device 11 can also use beamforming to improve the signal-to-noise ratio of the forward link.

In addition, compared with the way in which the network device 11 sends signals to all its communication devices through a single antenna or multiple antenna transmit diversity, when the network device 11 uses beamforming to send signals to the communication devices 21 randomly dispersed in the relevant coverage area, the phase Mobile devices in neighboring cells experience less interference.

At a given time, the network device 11 and the communication device 21 may be a wireless communication transmitting apparatus and / or a wireless communication receiving apparatus. When transmitting data, the wireless communication transmitting device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (for example, generate, receive from another communication device, or save in a memory, etc.) a certain number of data bits to be transmitted to the wireless communication receiving device through a channel. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to generate multiple code blocks.

In addition, the communication system shown in FIG. 1 may be a PLMN network, a D2D network, an M2M network, an IoT network, or other networks. FIG. 1 is only a simplified schematic diagram of an example. The network may also include other network devices or communication devices. Not drawn.

In order to facilitate understanding, before introducing the information communication method and apparatus of the present application, the related terms and principles involved in the embodiments of the present application will be described below with reference to FIGS. 2, 3 and 4.

FIG. 2 is a schematic structural diagram of a DRX cycle in the prior art. As shown in Figure 2, discontinuous reception (DRX) is a technology used to reduce the power consumption of terminal equipment in long-term evolution (LTE) communications. The network equipment is in the connected state and idle state. And inactive terminal equipment is configured with DRX function. For example, as shown in FIG. 2, for a terminal device configured with a DRX function, in each DRX cycle, the terminal device is in an activated state (On-Duration) at the previous part of each DRX cycle, and monitors the physical downlink shared channel. (physical downlink control channel, PDCCH); and the sleep time after the DRX cycle activation time enters the sleep state, and no PDCCH monitoring is performed. At the same time, the network device will ensure that the PDCCH is sent to the terminal device at the activation time in the DRX cycle of the terminal device. Specifically, DRX technology in LTE. The DRX function control entity is located at the MAC layer of the protocol stack. Its main function is to control the sending of instructions to the physical layer to notify the physical layer that listening to the PDCCH at a specific time is in the active period, and the reception will not be turned on for the rest of the time. Antenna, terminal equipment is in sleep state. As a result, the terminal device will not be in the state of monitoring the PDCCH all the time, and the purpose of saving power consumption and improving battery life of the terminal device is achieved, thereby improving the user experience of the terminal device.

In a new radio (NR) system, because the proportion of high-speed data transmission services increases and the maximum rate increases significantly, the data communicated between terminal equipment and network equipment may be generated in a burst and in a short time carry out. In order to further improve the performance of terminal equipment, NR may provide additional indication information on the basis of DRX (It should be noted that all the indication information in this application can also be referred to as a terminal power saving signal (UE power saving signal signal, UPSS), the two are the same) mechanism, the terminal device needs to determine whether the terminal executes the DRX mechanism in each DRX cycle according to the acquired instruction information, that is, whether to activate the DRX cycle corresponding to the instruction information according to the instruction information It is in an active state and monitors the PDCCH or receives a physical downlink shared channel (PDSCH). Enables the network device to wake up the terminal device at the activation time in the DRX cycle and to be in the activated state to monitor the PDCCH when it is determined that the PDCCH exists in the activation time of a DRX cycle, otherwise the terminal device is always in a sleep state To further save power consumption of terminal equipment. Among them, two common types of indication information include: a wake-up signal (WUS) and a go-to-sleep signal (GTS), which are respectively described below.

When the indication information is WUS, the indication information is used to indicate whether the terminal monitors the PDCCH, or the terminal is monitored to monitor the PDCCH; or, the indication information is used to indicate whether the terminal receives the PDSCH, or instruct the terminal to receive the PDSCH. Specifically, in the WUS mechanism, if a terminal device receives a WUS signal corresponding to a DRX cycle, it is activated in the DRX cycle and monitors the PDCCH or receives a PDSCH; if the terminal device does not receive a WUS signal corresponding to the DRX cycle, Do not listen to the PDCCH or receive the PDSCH in the sleep state during the DRX cycle. Optionally, the indication information may be sent before the activation time of the corresponding DRX cycle or during the activation time of the corresponding DRX cycle. For the terminal device in the RRC idle state, the indication information is sent before the DRX cycle; for the terminal device in the RRC connected state, And for the terminal device configured with the DRX function, the indication information can be sent before the DRX cycle or during the activation time of the DRX cycle. In addition, when the network device sends the instruction information to the terminal device, it does not send the instruction information to the terminal device every DRX cycle, but decides whether to send the instruction information according to the policies such as the service arrival situation and service delay requirements. Therefore, it is possible for the terminal device to detect the indication information sent by the network device to other terminal devices in advance of the DRX time indicated by the network device, and then the terminal device can distinguish the instruction information of different terminal devices in a code division manner. In addition, when receiving the instruction information, the terminal device only needs to enable a part of the receiving circuit corresponding to the instruction information in the terminal device, and the monitoring time is short.

For example, FIG. 3 is a schematic diagram of the application of WUS in the prior art, where the instruction information is WUS and the instruction information is sent before the DRX cycle of the DRX cycle as an example for illustration. The time difference between the activation time of the DRX cycle and the reception of the WUS instruction information It is recorded as GAP in advance. When the network device and terminal device are configured in advance at a specific GAP in advance, the network device sends instruction information to the terminal device in the advance time of the DRX cycle, and the terminal device receives the instruction sent by the terminal device in the advance time of the DRX cycle. information. As shown in FIG. 3, if a network device determines that a terminal device has a PDCCH or a PDSCH scheduled by the terminal device or multiple terminal devices in the DRX cycle ①, a WUS instruction is sent to the terminal device in advance of the DRX cycle ① to wake up the terminal device. After receiving the WUS, the terminal device is in the active state within the DRX cycle ① corresponding to the WUS and is monitoring the PDCCH or PDSCH. If the network device determines that the terminal device does not have a PDCCH or PDSCH scheduled by the terminal device or multiple terminal devices in the DRX cycle ②, the WUS is not sent to the terminal device in advance before the DRX cycle ②, and the terminal device is in the DRX cycle ② If no WUS has been received before, the terminal device is in the sleep state for the entire period of the DRX cycle ②. It should be noted that the heights of the various signals as shown in FIG. 3 are only used to characterize the relative currents or power levels monitored by the various signals.

When the indication information is GTS, the indication information is used to indicate whether the terminal monitors the PDCCH or the terminal does not monitor the PDCCH; or the indication information is used to indicate whether the terminal receives the PDSCH or the terminal does not receive the PDSCH. Specifically, in the GTS mechanism, if a terminal device receives a GTS signal corresponding to a DRX, it does not listen to the PDCCH or receive a PDSCH during the DRX cycle; if the terminal device does not receive a WUS signal corresponding to the DRX cycle, Then it is in the active state in this DRX cycle and monitors the PDCCH or receives the PDSCH.

For example, FIG. 4 is a schematic diagram of the application of GTS in the prior art, and the same description is given by using an example in which the indication information is sent before the DRX cycle of the DRX cycle, where the indication information is GTS. The time difference between the activation time of the DRX cycle and the reception of the GTS indication information is recorded as the GAP in advance. When the network equipment and the terminal equipment are configured in advance with a specific GAP in advance, the network equipment sends instruction information to the terminal equipment in the advance time of the DRX cycle. The terminal device receives the indication information sent by the terminal device in advance of the DRX cycle. As shown in FIG. 4, if the network device determines that the terminal device does not exist in the DRX cycle ③ or the PDCCH or PDSCH scheduled by the terminal device or multiple terminal devices, the GTS sends the GTS to the terminal device in advance before the DRX cycle ③. When the device receives the GTS, the terminal device is in a sleep state for the entire period of the DRX cycle ③ corresponding to the GTS. If the network device determines that the terminal device has a PDCCH or PDSCH scheduled by the terminal device or multiple terminal devices during the DRX cycle ④, the GTS is not sent to the terminal device in advance before the DRX cycle ④, and the terminal device is before the DRX cycle ④ If the GTS is not received, the activation time of the terminal device during the DRX cycle ④ is in the active state and the PDCCH or PDSCH is monitored. It should be noted that the heights of various signals as shown in FIG. 4 are also only used to characterize the relative current or power magnitude of various signal monitoring.

Although in the prior art, the use of instruction information such as WUS and GTS can enable network devices to determine the existence of PDCCH or PDSCH of one or more terminal devices within the activation time of a certain DRX cycle. The terminal device wakes up during the activation time in the DRX cycle, and keeps the terminal device active to monitor the PDCCH or receive PDSCH within the activation time, otherwise the terminal device is always in a sleep state even during the entire DRX cycle, and therefore in a certain period The power consumption of the terminal equipment is saved to a certain extent. However, in the prior art, when the terminal device uses the instruction information, it can only be used in WUS or GTS. The network device only configures one of the WUS mechanism or the GTS mechanism for the terminal device, and for each terminal There is no clear basis for judging which kind of indication information is specifically configured.

In this way, for a terminal device configured with the WUS mechanism, the network device needs to send the instruction information WUS to the corresponding terminal device before each DRX cycle that needs to monitor the PDCCH or receive the PDSCH, so that the corresponding terminal device processes the instruction information and The activation time of the DRX cycle is active. Once a terminal device configured with the WUS mechanism has frequent services, the terminal device needs to receive and process an additional WUS instruction message before each DRX cycle. This not only does not save the power consumption of the terminal device, but also provides frequent instructions. The reception and processing of information increases the power consumption of the terminal equipment. For a terminal device configured with the GTS mechanism, the network device will only send an instruction GTS to the terminal device before it needs to monitor the PDCCH and receive the DRX cycle of the PDSCH. Once the terminal device configured with the GTS mechanism is infrequent, each The terminal device in the sleep mode before the DRX cycle also needs to receive and process a GTS indication message, and similarly, the power consumption of the terminal device can be saved to a limited extent. Therefore, how to overcome the aforementioned problems in the current application of power-saving signals is a technical problem to be solved urgently at present.

Therefore, the present application provides a communication method of indication information, so that when a switching condition of the indication information is satisfied, the network device sends a switching command to the terminal device. After the terminal device makes the switching command effective, both the network device and the terminal device Another type of indication information is used between them to meet different usage scenarios and dynamic changes of services of the terminal device, and further reduce the power consumption and communication overhead of the terminal device.

The instruction information communication method in the embodiment of the present application will be specifically described below with reference to the accompanying drawings.

FIG. 5 is a schematic flowchart of an embodiment of an information communication method according to the present application. The embodiment shown in FIG. 5 can be executed in the communication system shown in FIG. 1, and the method for communicating instruction information shown in FIG. 5 includes:

S101: The network device generates a switching command, where the switching command is used to switch the type of the indication information from the first type to the second type.

Specifically, in S101, when the network device determines that the type of the indication information of the terminal device is switched from the first type to the second type, it generates a switching command for instructing the type of the indication information of the terminal device to be switched from the first type to The second type. It should be noted that the type of the instruction information used by the terminal device before S101 is the first type, that is, the terminal device determines whether to perform the monitoring step according to monitoring the first type of instruction information. After a network device determines that the type of instruction information of a terminal device needs to be switched, a network device generates a switch command and sends it to the terminal device to instruct the terminal device to switch the type of instruction information, so that the terminal device changes the type of instruction information from the first The type is switched to the second type, and whether to perform the monitoring step is determined according to the instruction information of the second type. The monitoring step described in this embodiment may be: the terminal device determines whether to monitor the physical downlink control channel PDCCH, or monitors the PDCCH, or does not monitor the PDCCH according to whether the terminal device receives the instruction information from the network device; or determines whether to receive the physical downlink sharing Channel PDSCH, or receive PDSCH, or not receive PDSCH.

Optionally, the types of the indication information in this embodiment include at least: a sleep signal GTS and a wake-up signal WUS, and the first type is different from the second type. Then further optionally, if the first type of indication information is GTS, the second type of indication information is WUS; if the first type of indication information is WUS, the second type of indication information is GTS.

Optionally, a possible representation form of the handover command generated by the network device in this embodiment is that the handover command is used to represent a certain type of indication information, or the handover command is used to represent a certain type by using one or more parameters carried by the handover command. A type of instruction information, for example, a specific bit in a switching command is specified to indicate the type of the instruction information. When the bit of the switching command is "0", the switching command is used to instruct the type of the instruction information to be switched Is the first type; or when the bit of the switching command is "1", the switching command is used to instruct to switch the type of the indication information to the second type. For example, in S101 of this embodiment, the switching command is used to switch the type of the indication information from the first type to the second type, and then the value of the specific bit of the switching command is "1".

Alternatively, another possible representation form of the handover command generated by the network device in this embodiment is that the handover command includes a type switching instruction of the instruction information, but does not include the type of the instruction information. That is, the network device only uses the switch command to inform the terminal device whether the type of instruction information needs to be switched. When the type of instruction information needs to be switched, the terminal device determines the type of the instruction information from the first type to the second. Types of. For example, when the switching command is "1", it is used to instruct the terminal device to switch the type of instruction information, and when the switching command is "0", it is used to instruct the terminal device not to switch the type of instruction information. Alternatively, only the type of the switching instruction information used to instruct the terminal device when the switching command is "1" may be specified, and the type of the switching instruction information is determined when the switching command received by the terminal device is "1", and other valued switching is received When a command is not received or a switch command is not received, the terminal does not switch the type of the indication information. After the terminal device receives the switching command, the terminal device performs the switching of the specific instruction information. Here, only the representation form of the handover command is described. The terminal device specifically determines the second type of indication information of the handover according to the handover command, which will be described in S103 in the subsequent embodiment of the present application.

S102: The network device sends a handover command to the terminal device; then the terminal device receives the handover command from the network device.

Specifically, in S102, the network device sends the handover command generated in S101 to the terminal device, and accordingly, the terminal device receives the handover command sent from the network device.

Optionally, the network device may send the handover command to the terminal device in the following form: downlink control information (DCI), MAC CE, or carried in DCI, MAC CE, radio resource control (RRC) In signaling or in system information.

When the types of instruction information used by all terminal devices in the cell where the terminal device is located are the same, if the type of instruction information of one terminal device in the cell is switched, the types of instruction information of other terminal devices in the cell need to be correspondingly changed. Switch. When the network device sends a handover command to the terminal device, one possible way is to bear the handover command in the system information to broadcast to all terminal devices in the cell where the terminal device is located. When all the terminal devices in the cell receive the After the system information, all terminal devices switch the type of instruction information according to the switch command carried in the system information. It should be noted that the system information here may be any existing system information or new system information communicated between the terminal device and the network device. The switching command may be carried by one or more specific bits or idle bits in the system information. For example, the switch command is used to indicate that when the type of the terminal device is switched, the corresponding bit value is "1" or the corresponding multiple bit values are "10". When the switch command is used for the indication information of the terminal device, When the type does not need to be switched, the corresponding one bit value is "0" or the corresponding multiple bit values are "01"; for example, the switching command may also indicate the terminal device's indication information through multiple bits. There are multiple types of switching. If the terminal device can be configured with four types of indication information, the switching command can instruct the terminal device to switch to a one-to-one corresponding four through "00", "01", "10", and "11" respectively. Types of instructions.

When the types of instruction information used by terminal devices in the cell where the terminal device is located do not need to be consistent or may not be the same, the handover command sent by the network device to the terminal device can be through a specially set physical layer signal or an existing physical The layer signal DCI, a specially set or existing MAC CE indicates the handover command, or the handover command is carried in a specific bit in the existing or new DCI, MAC CE or RRC signaling. For example, the handover command may be carried by one or more specific bits in the MAC CE. For a specific bit, the handover command is used to indicate the type of instruction information of the terminal when the bit value in the MAC CE is "1", and the handover command is used to indicate that the type of instruction information of the terminal does not need to be switched In MAC CE, the value of this bit is "0". For example, the switch command can indicate the type of the switching information of the terminal device through multiple specific bits. If the terminal device can be configured with four types of indicating information, the switching is The command can instruct the terminal device to switch to the corresponding type of instruction information through "00", "01", "10", and "11", respectively.

S103: The terminal device determines the second type of configuration information according to the switching command.

Specifically, in S103, the terminal device processes the handover command received in S102, and the terminal device determines the second type of configuration information according to the handover command. Among them, before S101, the terminal device determines whether to perform the monitoring step by monitoring the first type of instruction information, and the switching command received in S102 is used to instruct the terminal device to switch the type of the instruction information, and it is switched to monitoring the second type of instruction The information determines whether to perform the monitoring step. Therefore, S103 can be understood as that the terminal device takes effect the switch command from the network device, that is, the terminal device configures the monitoring of the second type of instruction information to implement the instruction information switching, or more specifically Monitor the first type of configuration information to modify / switch to the second type of configuration information.

Optionally, the terminal device may configure / store different configuration information corresponding to different types of indication information in advance. When receiving the switching command, the terminal device may directly select and execute the configured corresponding type of configuration according to the type indicated by the switching command. Information or obtain corresponding configuration information stored in the storage space and perform configuration.

Optionally, determining the second type of configuration information in this embodiment includes at least the following steps: If the terminal device determines that the terminal device monitors the first type of instruction information and the monitoring circuit used by the second type of instruction information is different, the terminal device Switching the detection circuit for monitoring the first type of instruction information to a monitoring circuit for monitoring the second type of instruction information; and / or, if the terminal device determines that the terminal device monitors the first type of instruction information and the second type of instruction information The monitoring locations used by the instruction information are different, and the terminal device switches the monitoring location of the first type of instruction information to the monitoring location of the second type of instruction information.

Specifically, because different types of instruction information may have different signal designs, which causes terminal devices to use different detection circuits or receive locations when receiving different types of instruction information, in this step, the terminal device is configured with the second type. When configuring the configuration information, the first type of instruction information needs to be compared with the second type of instruction information. If the signal design of the first type of instruction information and the second type of instruction information are the same, or the terminal device receives the same configuration information used by the first type of instruction information and the second type of instruction information, the terminal may be placed before The first type of configuration information used when monitoring the first type of instruction information is directly used as the second type of configuration information, and there is no need to change the existing configuration information of the terminal device. Conversely, if the terminal device determines that the signal design of the first type of indication information and the second type of indication information are different, it is necessary to change the configuration information of the related indication information. Wherein, if the monitoring circuit used for monitoring the first type of instruction information is different from the monitoring circuit used for monitoring the second type of instruction information, it is necessary to adjust the monitoring circuit of the terminal device to the second type in this step. Instructions for the monitoring circuit used. If the receiving location of the terminal device for receiving the first type of instruction information is different from the receiving location of the second type of instruction information, in this step, it is necessary to adjust the receiving location of the terminal device's instruction information to the second type of instruction. Where the message was received. For example, the receiving location here may be a time domain location, a frequency domain location, or a time-frequency location where the terminal device receives the indication information. In addition, if the terminal device determines that the signal design of the first type of instruction information and the second type of instruction information are different, the configuration information of the first type of instruction information may also be changed to the configuration information of the second type of instruction information. The information may also be a scrambling mode of the indication information or an encryption and decryption mode of the indication information.

Optionally, after S102 and before S103, the method further includes: the terminal device starts a timer for a preset time; and executes S103 after the timer expires. Specifically, the terminal device may not execute immediately after receiving the handover command according to the service arrival situation of the terminal device, service delay requirements, or other policies of the terminal device, but may start a timer of a preset time, the preset here The time can be adjusted by terminal equipment or network equipment according to business needs to meet the needs of different services. When the timer expires, the terminal device performs the configuration of the second type of configuration information in S103 again. Before the timer expires, the terminal device still maintains the first type of configuration information of the first type of instruction information before receiving the handover command, and determines whether to perform the monitoring step by using the first type of instruction information; Determine the second type of configuration information, and use the second type of indication information to determine whether to perform the monitoring step.

Optionally, as described in an embodiment of S101, if the handover command includes only the type of indication information and the handover command does not include the specific type of indication information, the terminal device in S103 also needs to first perform After determining the second type of indication information to be switched, then determine the configuration information corresponding to the second type of indication information.

For a terminal device, one possible processing method of this type of switching command is that if the terminal device is configured with only two types of instruction information, once the terminal receives the switching command, it switches the currently configured instruction information to Another type. For example, taking GTS and WUS as examples, the terminal device monitors the GTS to determine whether to perform the monitoring step, and after receiving the switch command, the terminal device determines to switch the type of the instruction information from GTS to WUS, and then determines the corresponding type of the instruction information WUS Configuration information and determine whether to perform the listening step through WUS.

Another possible implementation manner is that when the terminal device receives the handover command, it determines the second type of configuration information according to three factors, namely, the handover command, the currently configured first type of indication information, and the handover relationship. The switching relationship includes a conversion relationship between various types of indication information. The switching relationship can be configured in advance by the terminal device and stored in the storage device of the terminal device; or the switching relationship can also be carried in the switching command and sent by the network device to the terminal device in real time. Such a switching relationship can also be controlled by the network device according to the service situation Adjust switching relationships in real time. It is assumed that the terminal device can monitor three types of indication information A, B, and C. Therefore, the switching relationship of the terminal device includes three conversion relationships: AB, BC, and CA. When the terminal device receives the switching command, it needs to Switch the type of instruction. For example, the terminal device determines whether to perform the monitoring step by monitoring type A instruction information. After the terminal device receives the switching command, the terminal device jointly determines that the type of the instruction information needs to be switched from type A to B according to the switching command, the type A of the monitoring information currently being monitored, and the conversion relationship of "AB" in the switching relationship. Type, that is, determining that the second type of configuration information is type B configuration information corresponding to type B instruction information. After the switching command takes effect, it is determined whether to perform the monitoring step by monitoring type B instruction information. It should be noted that the switching relationship here is only an example, and the switching relationship may further include more types of conversion relationships such as A-C, B-C, and C-A, which are not limited herein.

Optionally, after S103 and before S104, the method further includes: the terminal device sends handover confirmation information to the network device; wherein the handover confirmation information is used to notify the network device that the terminal device has performed the second type of configuration information determined in S103, that is, The terminal device has enabled the handover command and configured the second type of configuration information, and has been able to perform monitoring the second type of instruction information. Therefore, after the terminal device has made the switching command effective through S103, the terminal device can send confirmation information to the network device for confirmation, so that both the network device and the terminal device confirm that the type of the instruction information is switched. Therefore, it is avoided that the performance of the terminal device or the network delay caused by the instruction information communication, when the terminal device has not been configured with the second type of configuration information, and cannot monitor the second type of instruction information, the network device has already sent the terminal to the terminal. The device sends the second type of indication information.

S104: The terminal device monitors the second type of indication information according to the second type of configuration information.

Specifically, in this embodiment, after the terminal device determines the second type of configuration information through S103, it monitors the second type of indication information according to the second type of configuration information. Wherein, monitoring the second type of indication information includes: determining whether to perform the monitoring step according to whether the second type of indication information is received. At this point, the terminal device completes switching the type of the instruction information according to the switching command, and the terminal device changes from monitoring the first type of instruction information to monitoring the second type of instruction information before receiving the switching command. Optionally, the monitoring step is: the terminal determines whether to monitor the physical downlink control channel PDCCH, or monitors the PDCCH, or does not monitor the PDCCH according to whether the terminal receives the second type of indication information from the network device; or determines whether to receive the PDCCH The physical downlink shared channel PDSCH either receives the PDSCH or does not receive the PDSCH.

Optionally, the switching command sent by the network device to the terminal device further includes a duration of the switching command. That is, after receiving the switching command and executing S103, the terminal device executes the monitoring of the second type of instruction information according to the second type of configuration information in S104 within the duration; and after the duration, the terminal device determines and configures the first A type of configuration information, and monitoring the first type of indication information according to the first type of configuration information. Therefore, the network device can instruct the terminal device to switch to monitoring the second type of instruction information within a certain time according to the service requirements. After this period of time, the terminal device resumes monitoring the first type of instruction information before receiving the switching command, which improves the flexibility of the instruction information switching and enriches the application scenario.

In summary, in the method for communicating instruction information provided in this embodiment, a switching command generated by a network device and sent to a terminal device is used to switch the type of instruction information from a first type to a second type, so that the terminal device After receiving the switching command, the second type of configuration information is determined according to the switching command, and the second type of indication information is monitored according to the second type of configuration information. Therefore, the terminal device can switch different instruction information for communication, thereby satisfying different usage scenarios and dynamic changes of services of the terminal device, improving the switching flexibility of the terminal instruction information, and further reducing the power consumption and communication overhead of the terminal device.

Further, in the above embodiments, the communication scenario of the terminal device is not limited, and the instruction command sent by the network device to the terminal device does not limit the processing of a certain communication or a certain communication type of the terminal device. That is, after the terminal device receives the switching command, it applies the switching of the type of instruction information indicated by the switching command to all possible communication scenarios of the terminal device. For example, in a carrier aggregation (CA) communication scenario, a terminal device has multiple component carriers (CCs) with instructions that need to be monitored, or the terminal device has one or more bandwidths on its carrier. In part (bandwidth part, BWP) communication scenarios, one or more BWPs also have indication information that needs to be monitored. At this time, the terminal device applies the switching of the indication information type to all activated CCs or all activated BWPs of the terminal device. Although such a handover has achieved the purpose of switching the type of the instruction information, when the terminal device processes different services on each CC or each BWP, the network device cannot perform the switching on different CCs or different BWPs according to the handover command. Different services give instructions for switching the type of instruction information, and cannot accurately switch the type of instruction information for one or some activated CCs or activated BWPs. Therefore, in order to solve the above problems, enrich the application scenarios of the handover command, and improve the instruction efficiency of the handover command, based on the foregoing embodiments, this application also provides a method for communicating information of instructions, so that the terminal device can perform handover according to the network device. The command determines the type of indication information to switch on a specific CC or a specific BWP.

Wherein, based on the foregoing, the steps performed by the terminal device in S103 provided in this embodiment are: the terminal device determines at least one activated CC or a second type indication on at least one activated BWP according to the switching command and the mapping relationship. Information and its configuration information; the step performed by the terminal device in S104 is: the terminal device monitors the second type of indication information on at least one activated CC or at least one activated BWP according to the second type of configuration information. Specifically, this embodiment can be implemented in the following manner. The switching command provided in this embodiment includes: at least one parameter. At least one parameter has a mapping relationship with at least one activated component carrier CC or at least one activated bandwidth part BWP; at least one parameter is used to indicate that there is a mapping relationship between at least one activated CC or at least one activated BWP. The type of indication information is from The first type is switched to the second type. Corresponding to the above embodiment,

Optionally, the mapping relationship here can be configured in advance by the network device in the terminal device, and the terminal device can be used when needed. Alternatively, the mapping relationship may also be carried in a handover command.

It should be noted that the parameters included in the handover command described in the embodiments of the present application may be a command or information represented by at least one bit, and each parameter may be regarded as the parameter independently. Corresponding activated CC or activated BWP switching command indicating the type of information.

The following describes the embodiment according to the method of switching the indication information type in four different application scenarios of the terminal device.

The first application scenario is that when a terminal device communicates with a non-CA, there is only one communication carrier and there is only one activated BWP on the carrier. The switch command at this time may include: a parameter. At this time, after receiving the switching command, the terminal device determines the type of the instruction information for switching the activated BWP according to the switching command. Assuming that the activated BWP originally monitors the first type of indication information, the terminal device needs to determine the second type of configuration information on the activated BWP according to the switching command, and then use the second type of configuration information on the activated BWP. Monitor the second type of instruction. The implementation process of this embodiment is the same as the process shown in FIG. 5, and the implementation method and principle are the same as those in FIG. 5, and details are not described again.

The second application scenario is that when a terminal device communicates with a non-CA, there is only one communication carrier and there are multiple activated BWPs on the carrier. Then the switching command at this time may include: at least one parameter; the mapping relationship includes: when the at least one parameter is multiple parameters, a one-to-one correspondence between multiple parameters and multiple activated BWPs; or, at least one parameter is one When there are multiple parameters, the corresponding relationship between each parameter in at least one parameter and multiple activated BWPs; or when the at least one parameter is multiple parameters, the parameter combination of multiple parameters in the at least one parameter and multiple Correspondence between activated BWP. In this way, the switching command received by the terminal device from one activated BWP can be realized, and the type of instruction information on other activated BWPs can be switched.

That is, the mapping relationship of this embodiment includes three possible implementation modes: ①, when at least one parameter is multiple parameters, each parameter of the multiple parameters corresponds to an activated BWP, and the two are in a one-to-one relationship. For example, there are 3 activated BWPs on a carrier for non-CA communication of the terminal equipment. Since the 3 activated BWPs may carry different services, the network equipment wishes to perform PDCCH monitoring or PDSCH reception on the three activated BWPs of the terminal equipment separately. control. Therefore, the switch command can include 3 parameters. It is assumed that the 3 parameters in the form of bits are “000”, and the mapping relationship is that each bit corresponds to 3 activated BWPs, and the corresponding activation is assumed when the parameter is 1. Switch the type of instructions on the BWP. Then, when the terminal receives the handover command "100", it is determined according to the handover command and the mapping relationship that the type of the indication information on the first activated BWP needs to be handed over, and a subsequent handover action is performed. ② Each parameter of at least one parameter corresponds to multiple activated BWPs, and the two are in a one-to-many relationship. When at least one parameter is one, the one parameter is used to correspond to all activated BWPs in the multiple activated BWPs. When at least one parameter is multiple, each parameter may correspond to a different multiple activated BWPs, respectively. For example, if there are 4 activated BWPs on a carrier for non-CA communication of a terminal device, and the switch command is a parameter, the mapping relationship may be a one-to-many correspondence between a parameter and the 4 activated BWPs. Or, when the switching command is two parameters, the mapping relationship may be a one-to-many correspondence between one parameter and two of the activated BWPs, and a correspondence between the other parameter and the other two activated BWPs. . Assume that the two parameters in the bit form are "00" and the mapping relationship is that the first bit and the second bit correspond to the two activated BWPs before and after, respectively. When the terminal device receives the handover command "10", according to the handover command And the mapping relationship determines that the types of indication information on the first two activated BWPs among the four activated BWPs need to be switched. ③ At least one parameter is multiple parameters, and there is a corresponding relationship between multiple parameters and multiple activated BWPs. For example, assuming that the switch command includes at least 3 parameters "000" and assuming that there are 8 activated BWPs, the 3 parameters can correspond to any one or more of the 8 activated BWPs, for example: 000 corresponds to all 8 Activated BWP; 001 corresponds to the first activated BWP; 010 corresponds to the first two activated BWP, etc. Alternatively, any one of a plurality of parameters may form a parameter combination, and any of a plurality of activated BWPs may also form a BWP combination to establish a correspondence between the parameter combination and the BWP combination. . For another example, the three parameters in the above example can also form a correspondence relationship between the parameter combination and the BWP combination in the form of a combination. For example, three parameters can be combined into eight parameter combinations as: "000" "001" ... "111 According to the IDs of the 8 activated BWPs are 1-8 respectively, then the 8 activated BWPs can form at least 8 different BWP combinations, which are recorded as: Combination 1: 1; Combination 2: 1-2; ... Combination 8 : 1-8. Then the 8 parameter combinations formed by the 3 parameters in the switch command can be in one-to-one correspondence with 8 different BWP combinations in the 8 activated BWPs, such as the parameter combination "000" corresponding to BWP combination 1; the parameter combination "001" corresponding to BWP Combination 2; ...; The parameter combination "111" corresponds to BWP combination 8.

The third application scenario is that when a terminal device communicates with a CA, there are multiple activated CCs and only one activated BWP exists on each activated CC. Then the switching command at this time may include: at least one parameter; the mapping relationship includes: when the at least one parameter is multiple parameters, a one-to-one correspondence between multiple parameters and multiple activated CCs; or at least one parameter is one When there are multiple parameters, the corresponding relationship between each parameter in at least one parameter and multiple activated CCs; or, when the at least one parameter is multiple parameters, the parameter combination consisting of multiple parameters in at least one parameter and multiple Correspondence between activated CCs. In this way, the switching command received by the terminal device from one activated CC can be realized, and the type of instruction information on other activated CCs can be switched. In particular, during the CA communication, the network device may send the handover command only on the CC of the primary cell, and can implement the switching of the indicated information type on the CC of the primary cell and / or any activated secondary cell.

Similarly, the mapping relationship of this embodiment includes three possible implementation modes: ① When at least one parameter is multiple parameters, each parameter of the multiple parameters corresponds to an activated CC, and the two are in a one-to-one correspondence relationship. For example, when the terminal equipment CA communicates with three activated CCs, since the three activated CCs may carry different services, the network equipment wishes to control the PDCCH monitoring or PDSCH reception on the three activated CCs of the terminal equipment separately. Therefore, the switch command can include 3 parameters. It is assumed that the 3 parameters in the form of bits are “000”, the mapping relationship is that each bit corresponds to 3 activated CCs, and the corresponding activation is assumed when the parameter is 1. The type of the indication information on the CC is switched. Then, when the terminal receives the handover command "100", it is determined according to the handover command and the mapping relationship that the type of the indication information on the first activated CC needs to be handed over, and a subsequent handover action is performed. ② Each of the at least one parameter corresponds to multiple activated CCs, and the two are in a one-to-many relationship. When at least one parameter is one, the one parameter is used to correspond to all activated CCs in the multiple activated CCs; when at least one parameter is multiple, each parameter may correspond to a different multiple activated CCs, respectively. For example, when the terminal equipment CA communicates with four activated CCs, when the switching command is a parameter, the mapping relationship may be a one-to-many correspondence between a parameter and the four activated CCs. Or alternatively, when the switch command is two parameters, the mapping relationship may be a one-to-many correspondence between one parameter and two of the activated CCs and a correspondence between the other parameter and the other two activated CCs. . Assume that the two parameters in the bit form are "00", and the mapping relationship is that the first bit and the second bit correspond to the two activated CCs before and after, respectively. When the terminal device receives the switch command "10", according to the switch command And the mapping relationship determines that the types of indication information on the first two activated CCs among the four activated CCs need to be switched. ③ At least one parameter is multiple parameters, and there is a corresponding relationship between a parameter combination composed of multiple parameters and multiple activated CCs. For example, assuming that the switch command includes at least 3 parameters "000" and assuming that there are 8 activated CCs, the 3 parameters can correspond to any one or more of the 8 activated CCs, for example: 000 corresponds to all 8 Activated CC; 001 corresponds to the first activated CC; 010 corresponds to the first two activated CCs. Alternatively, any one of a plurality of parameters may form a parameter combination, and a plurality of activated CCs among a plurality of activated CCs may also form a CC combination to establish a correspondence relationship between the parameter combination and the CC combination. For another example, the three parameters in the above example can also form a correspondence relationship between the parameter combination and the CC combination in the form of a combination. For example, three parameters can be combined into eight parameter combinations as: "000" "001" ... "111" ; According to the IDs of the 8 activated CCs are 1-8, the 8 activated CCs can form at least 8 different CC combinations, which are recorded as: Combination 1: 1; Combination 2: 1-2; ...; Combination 8 : 1-8. Then the 8 parameter combinations composed of 3 parameters in the switch command can correspond to the 8 activated 8 different BWP combinations one-to-one, such as the parameter combination "000" corresponding to CC combination 1; the parameter combination "001" corresponding to CC Combination 2; ...; The parameter combination "111" corresponds to CC combination 8.

The fourth application scenario is that when a terminal device communicates with a CA, there are multiple activated CCs and each activated CC has multiple activated BWPs. Then the switching command at this time may include: at least one parameter; the mapping relationship includes: when the at least one parameter is multiple parameters, one of the multiple parameters and each activated BWP in each activated CC in the multiple activated CCs A correspondence relationship; or, when at least one parameter is one or more parameters, a correspondence relationship between each parameter in at least one parameter and one or more activated BWPs in one or more activated CCs; or at least one parameter When there are multiple parameters, a correspondence between a parameter combination composed of multiple parameters in at least one parameter and one or more activated BWPs possessed by one or more activated CCs. That is, in this embodiment, it is not necessary to consider which activated CC each activated BWP comes from, and one or more activated BWPs corresponding to each parameter combination may be activated BWPs of the same or different activated CCs. Thereby, it is possible to implement a handover command received by the terminal device from one BWP possessed by an activated CC, and it is possible to switch over the types of indication information of other BWPs. In particular, during CA communication, the network device may send the handover command only on the CC of the primary cell, and can implement the indication information of the activated BWP on the CC of the primary cell and / or the CC of any activated secondary cell. Type switching.

Similarly, the mapping relationship in this embodiment includes three possible implementation modes: ① When at least one parameter is multiple parameters, each parameter in the multiple parameters corresponds to each activated BWP in each activated CC The correspondence relationship between the two is one-to-one correspondence. For example: There are 2 activated CCs when the terminal CA communicates, and each activated CC has 2 activated BWP, so the switching command needs to include 4 parameters, assuming that it is expressed as "0000" in bit form, where each parameter is Corresponding to a total of 4 activated BWPs on 2 activated CCs. ② Each parameter of the at least one parameter corresponds to multiple BWPs. Here, multiple activated BWPs may be possessed by one activated CC, or may be possessed by multiple activated CCs. For example, when at least one parameter is a parameter, the one parameter is used to correspond to all BWPs on all activated CCs, so the mapping relationship may be one between a parameter and a total of 4 activated BWPs on 2 activated CCs. Many-to-many correspondence. Or, when at least one parameter is multiple parameters, each parameter may respectively correspond to multiple BWPs on one or more activated CCs. For example, when the switch command is two parameters, the mapping relationship may include one of the parameters and The one-to-two correspondence between the first activated BWP of the first activated CC, the first activated BWP of the second activated CC, and the other parameter with the second activated CC A one-to-two correspondence between the second activated BWP and the second activated BWP of the second activated CC. Assuming that the two parameters in the bit form are "00", when the terminal device receives the handover command "10", the first activated BWP and the second one of the first activated CC are determined according to the handover command and the mapping relationship. The type of the indication information on the first activated BWP of the activated CC needs to be switched. ③ At least one parameter is a plurality of parameters, and there is a corresponding relationship between a parameter combination composed of a plurality of parameters and a plurality of BWPs possessed by one or more activated CCs. For example, it is assumed that the switching command includes at least 3 parameters "000", and it is also assumed that there are 2 activated CCs, each activated CC has 4 activated BWPs, and a total of 8 activated BWPs. The 3 parameters can correspond to any one or more of a total of 8 activated BWPs, for example: 000 corresponds to all 8 activated BWPs; 001 corresponds to the first activated BWP on the first activated CC; 010 corresponds to All activated BWPs on the first activated CC, etc. Alternatively, any of multiple parameters may form a parameter combination, and any of multiple activated BWPs in multiple activated BWPs in one or more activated CCs may also form an activated BWP group. Establish the correspondence between parameter combinations and BWP combinations, and multiple BWPs in a BWP combination can come from one or more activated CCs. For another example, the three parameters in the above example can be combined into eight parameter combinations: "000", "001" ... "111"; then a total of 8 activated BWPs can be combined to form at least 8 different BWP combinations. 1: 1; combination 2: 1-2; ... combination 8: 1-8. Then the 8 parameter combinations formed by the 3 parameters in the switch command can be in one-to-one correspondence with 8 BWP combinations, such as parameter combination "000" corresponding to BWP combination 1; parameter combination "001" corresponding to BWP combination 2 ... parameter combination " 111 "corresponds to BWP combination 8. The BWP group here may not consider which activated CC each activated BWP comes from, and the activated BWP included in each group may be activated BWP on the same or different activated CC.

Further, in each of the foregoing embodiments, the network device in S101 generates a switching command after determining that the instruction information of the terminal device needs to be switched from the first type to the second type. Specifically, how to make the network device determine that the handover command can be generated. This application provides several methods for determining the network device to determine the handover command, which will be described below with reference to FIGS. 6 and 7 respectively.

FIG. 6 is a schematic flowchart of an embodiment of an information communication method of the present application. The embodiment shown in FIG. 6 shows a method in which a terminal device determines whether to switch the type of instruction information according to a switching criterion. If the terminal device determines that the type of the instruction information needs to be switched, the terminal device sends a switching request to a network device to Request to switch the type of instruction information. As shown in FIG. 6, based on the embodiment shown in FIG. 5, before S101, this embodiment further includes:

S201: The terminal device determines that the service density between the terminal device and the network device meets the handover criterion; then executes S202: the terminal device sends a handover request to the network device; wherein the handover request is used to request the type of handover instruction information from the network device. In addition, if the terminal device determines that the service density between the terminal device and the network device does not meet the handover criteria, the terminal device will not send a handover request to the network device, and the network device will not perform the request without receiving the handover request. A subsequent S101 generates a switching command. That is, when the terminal device judges that the service density between the terminal device and the network device does not meet the handover criterion, the type of the indication information of the existing terminal device is not switched.

Optionally, the determination of the service density between the terminal device and the network device in S201 here may be configured to be performed periodically, and the terminal device executes the service between the terminal device and the network device in S201 at a fixed interval. Judgment of density.

Specifically, this embodiment provides a possible setting manner of a switching criterion as an example below. For example, the handover criterion includes: if the first type of indication information is GTS, the service density within a fixed time period T between the terminal device and the network device is lower than the first preset threshold; if the first type of indication information is WUS, the terminal The service density within a fixed time period T between the device and the network device is higher than a second preset threshold. Among them, the service density may be the number of data radio bearers (DRBs) of the terminal equipment, the sum of the throughput of each DRB of the terminal equipment, the average throughput of each DRB of the terminal equipment, or the maximum DRB throughput of the terminal equipment, Or the number of times the terminal device has been paged in a unit time.

Wherein, if the first type of indication information is GTS, for a terminal device configured with a GTS mechanism, the network device sends the indication information GTS to the terminal device only before or during a DRX cycle that does not need to monitor the PDCCH and receive the PDSCH. Therefore, once the terminal device determines that the service density between the terminal device and the network device is lower than the first preset threshold, the terminal device determines that its service is infrequent, and does not need to monitor the PDCCH or receive the PDSCH in most DRX cycles. It is required that the network device sends a GTS instruction to the terminal device before each DRX cycle. At this time, the first type of instruction information GTS needs to be switched to the second type of instruction information to reduce the transmission of the instruction information GTS. Preferably, the handover criterion may further instruct to switch the GTS to WUS when the service density is lower than the first preset threshold.

If the first type of instruction information is WUS, for a terminal device configured with the WUS mechanism, the network device needs to send the instruction information WUS to the terminal device before or during each DRX cycle that needs to monitor the PDCCH or receive the PDSCH, so that the terminal device can The instruction is processed and is active during the activation time of the DRX cycle. Therefore, once the terminal device determines that the service density between the terminal device and the network device is higher than the first preset threshold, the terminal device determines that its service is more frequent and needs to monitor the PDCCH or receive the PDSCH in most DRX cycles. It is not necessary for the network device to send a WUS instruction message to the terminal device before each DRX cycle. At this time, the first type of instruction information WUS needs to be switched to the second type of instruction information to reduce the transmission of the instruction information WUS. Preferably, the handover criterion may further instruct to switch the WUS to the GTS when the service density is higher than the second preset threshold.

Therefore, the present application provides a communication method of indication information, so that when the terminal device determines that the service density between the terminal device and the network device meets the handover criterion, the terminal device sends a handover request to the network device, and then the network device sends the request to the terminal. The device sends a switch command, so that the network device and the terminal device use different instruction information for communication, so as to meet different usage scenarios of the terminal device, improve the switching flexibility of the terminal instruction information, and further reduce the power consumption of the terminal device. Volume and communication overhead.

Optionally, in the embodiment shown in FIG. 6, after the network device receives the handover request sent by the terminal device in S202, the network device further needs to determine the handover request of the terminal device to determine whether the terminal device can perform It requests to switch the type of the indication information. If it is determined that the switching of the instruction information type can be performed, the network device executes S101 to generate a switching command of the terminal device; if it is determined that the switching of the instruction information type cannot be performed, the network device does not execute S101 to generate the switching command of the terminal device.

Optionally, when the network device determines that the type of indication information cannot be switched according to the switching request of the terminal device, the terminal device may notify the terminal device that the switching request is invalid in the form of a return message.

Specifically, this application provides two possible ways for a network device to determine whether a terminal device can switch the type of instruction information according to its switching request.

In a possible implementation manner, for application scenarios in which different terminal devices in the same cell use different instruction information, the network device determines whether the terminal device can perform handover after receiving the handover request of the terminal device. . The network device may determine whether the type of the instruction information of the terminal device can be switched by determining whether the switching request and / or other information meets a condition of the type of instruction information of the terminal device switching. For example, if the terminal device determines that the type of the instruction information needs to be switched to WUS according to the manner in the foregoing embodiment, it sends a switching request to the network device. After the network device receives the handover request sent by the terminal device, the network device considers the available resources on the network side according to the handover request of the terminal device. If the network resource overhead is large at this time, determine if the instruction information of the terminal device is switched to WUS After that, the overhead of network resources will be further increased, affecting the status of network resources, it is determined that the switching request of the terminal device cannot be responded to, that is, S101 is not executed; if the network resource overhead is small at this time, the instruction information of the terminal device may be allowed to switch to WUS , It is determined that the type of the indication information of the terminal device can be switched.

In another possible implementation manner, the types of indication information used by different terminal devices in the same cell need to maintain the same application scenario. After receiving a handover request from a terminal device, the network device needs to consider all terminals in the cell. device. Therefore, the network device determines the number of handover requests sent from all terminal devices in the cell where the terminal device is located. If the number is greater than a preset threshold, the network device determines the type of the terminal device's instruction information to perform handover; if the number is less than the preset threshold, Then the network device determines that the type of the indication information of the terminal device cannot be switched. Specifically, for an application scenario in which the same indication information is used by different terminal devices in the same cell, the network device needs to determine whether to switch the indication information used by all terminals in the cell from the overall perspective of the cell. For example, there are 10 terminal devices in a certain cell, all of which are configured with the first type of indication information. When a network device receives a handover request from a terminal device in the cell, it determines whether other handover requests have been received within a certain period of time. A handover request sent by a terminal device. If within a certain period of time of receiving the terminal device handover request, a handover request from the other 4 terminal devices is also received, and the number of terminal devices requesting the information type switching is more than half, determine the instructions for all terminal devices in the cell Information to switch. If a network device does not receive a handover request from another terminal device within a certain period of time after receiving a handover request from a terminal device in the cell, the handover request sent by the terminal is not processed, and the In a possible embodiment, the network device may also notify the terminal device that the handover request is not processed by way of feedback information.

FIG. 7 is a schematic flowchart of an embodiment of an information communication method according to the present application. The embodiment shown in FIG. 7 shows a manner in which the network device determines whether to switch the type of the indication information according to the switching criterion, and when the switching is needed, the network device sends a switching command to the terminal device. As shown in FIG. 7, based on the embodiment shown in FIG. 5, before S101, this embodiment further includes:

S301: The network determines that the service density between the terminal device and the network device satisfies a handover criterion; then executes the network device in S101 to generate a handover command. In addition, if the network device determines that the service density between the terminal device and the network device does not satisfy the handover criterion, S101 will not be performed. That is, when the network device judges that the service density between the terminal device and the network device does not satisfy the handover criterion, the type of the indication information of the existing terminal device is not switched.

Optionally, the determination of the service density between the network device and the terminal device in S301 here may also be configured to be executed periodically, and the network device performs the determination in S301 every fixed time interval.

Optionally, the handover criterion used by the network device to determine whether the service density is satisfied may be a handover criterion that may be used as described in the embodiment shown in FIG. 6. The specific judgment basis is the same, and details are not described again. Alternatively, the handover criterion here may be different from the handover criterion in the embodiment shown in FIG. 6.

It should be noted that when the network device in the embodiment shown in FIG. 7 determines that the type of instruction information of the terminal device needs to be switched, the form of the switching command generated by S101 is the same as that in the embodiment shown in FIG. 6 by the network. After the device receives the handover request sent by the terminal device, it uses the form of the handover command generated by S101. The two handover command forms may be the same or different.

For example, if the network device determines that the type of instruction information of the terminal device needs to be switched in the embodiment shown in FIG. 7, because the terminal device cannot determine whether the type of instruction information needs to be switched and how to switch the type of instruction information, the network device The switching command sent to the terminal device needs to include a specific type indicated by the network device, and the terminal device needs to switch the type of the instruction information according to the specific type.

For another example: in the embodiment shown in FIG. 6, when the terminal device determines that the type of handover instruction information is required, it sends a handover request to the network device, and the network device determines whether the terminal device can perform handover according to the handover request. Therefore, although the terminal device has determined that its instruction information needs to be switched after the judgment of S201, it is still necessary to send a handover request for the network device to determine whether the instruction information of the terminal device can be switched. If the network device determines that the instruction information of the terminal device is switchable, it generates a switching command and sends it to the terminal device. At this time, the switching command may not include the type of the instruction information or the type of the instruction information. Wherein, in the embodiment of FIG. 6, when the switching command does not contain the type of the indication information, the terminal device can determine the type of the indication information according to the switching command after receiving the switching command, and the type of the indication information can be switched to that determined by the terminal device in S201. After receiving the handover command, the terminal device determines the type of the instruction information that needs to be handed over according to the handover command, the type of the currently monitored instruction information, and the handover relationship. The handover relationship is the same. The terminal device may be configured in advance and stored in the terminal device, or the handover relationship may be carried in the handover command and sent by the network device to the terminal device in real time. In the embodiment of FIG. 6, when the switching command includes the type of the indication information, the type of the indication information in the switching command may be the same as or different from the type requested by the terminal device. After the terminal device receives the switching command, it Switch the type of instruction information in. The form of the handover command in the above embodiment is an example, and the specific form of the handover command is not limited in this application.

In summary, in the instruction information communication method provided in this embodiment, a network device or a terminal device can determine whether to switch the type of instruction information according to the service density between the two. If it is determined according to the judgment criterion that the type of instruction information needs to be judged , The network device sends a switching command to the terminal device, so that the terminal device completes the switching of the instruction information type, so that when the switching condition of the instruction information is satisfied, the network device and the terminal device can be switched according to the switching command sent by the network device to the terminal device. The users use different types of instruction information for communication, so as to meet different usage scenarios and dynamic changes of services of the terminal device, improve the switching flexibility of the terminal instruction information, and further reduce the power consumption and communication overhead of the terminal device.
