Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to an information indication method, apparatus, and terminal. Background Art

[0002] In traditional cellular network communication, uplink / downlink data and control information are transmitted between a terminal and a network-side device through the Uu interface. To solve the power consumption problem, the cellular network communication system adopts a Discontinuous Reception (DRX) operating mode. In this operating mode, the terminal periodically monitors the control channel, thereby achieving the purpose of power saving.

[0003] The basic principle of DRX is as Figure 1 shown. Among them, On duration represents the time period during which the terminal monitors the control channel. During this period, the radio frequency channel is turned on, and the control channel is continuously monitored; at other times except for On duration, the terminal is in a sleep state, and its radio frequency channel will be turned off and no longer monitor the control channel to achieve the purpose of power saving. On Duration appears periodically (Cycle), and the specific cycle is implemented by network-side configuration.

[0004] Direct communication means that neighboring terminals can transmit data through a direct communication link (also called Sidelink, abbreviated as SL) within a short distance range. The radio interface corresponding to the Sidelink link is called a direct communication interface, also called a Sidelink interface or a PC5 interface.

[0005] For the DRX of the direct communication interface, there is currently only one set of long DRX (long DRX) configurations. No matter what service reaches this direct communication interface, the direct communication terminal uses this set of DRX configurations, which cannot adapt to the delay requirements of different services and affects the user experience.

[0141] As Figure 3 shown, an embodiment of the present invention provides an information indication method, and the method includes:

[0142] Step 201, a first terminal sends indication information at a target position of a direct communication resource, and the indication information is used to indicate at least one of the following:

[0143] Indicate whether a second terminal needs to directly enter a Discontinuous Reception (DRX) active time;

[0144] Indicate whether a second terminal needs to directly enter a Discontinuous Transmission (DTX) active time;

[0145] Indicate whether a second terminal needs to perform a DRX configuration change;

[0146] Indicate whether a second terminal needs to perform a DTX configuration change;

[0147] Indicate the identification information of the DRX configuration corresponding to the second terminal after the DRX configuration change, such as the number of the DRX configuration;

[0148] Indicate the identification information of the DTX configuration corresponding to the second terminal after the DTX configuration change, such as the number of the DTX configuration;

[0149] Wherein, the second terminal is a terminal that directly communicates with the first terminal.

[0150] In an embodiment of the present invention, the indication information may further include: a direct communication source address (i.e., the address of the data sending terminal) and a direct communication destination address (i.e., the address of the data receiving terminal).

[0151] In an embodiment of the present invention, through the indication of the indication information, the first terminal and the second terminal can be synchronized to enter the active time, or the DRX configuration / DTX configuration of the first terminal and the second terminal can be synchronously changed to meet the delay requirements of different services and improve the user experience.

[0152] It should be noted that in direct communication, the first terminal can act as either a data sending terminal or a data receiving terminal; similarly, the second terminal can act as either a data receiving terminal or a data sending terminal. When the first terminal is a data sending terminal and the second terminal is a data receiving terminal, the indication information sent by the data sending terminal is used to indicate at least one of the following:

[0153] Indicating whether the second terminal needs to directly enter the discontinuous reception (DRX) activation time;

[0154] Indicating whether the second terminal needs to perform a DRX configuration change;

[0155] Indicating the identification information of the DRX configuration corresponding to the second terminal after the DRX configuration change.

[0156] When the first terminal is a data receiving terminal and the second terminal is a data sending terminal, the indication information sent by the data receiving terminal is used to indicate at least one of the following:

[0157] Indicating whether the second terminal needs to directly enter the discontinuous transmission (DTX) activation time;

[0158] Indicating whether the second terminal needs to perform a DTX configuration change;

[0159] Indicating the identification information of the DTX configuration corresponding to the second terminal after the DTX configuration change.

[0160] It should be noted that the first terminal can achieve the configuration transformation of DRX / DTX by means of the indication information sent at the target position of the direct communication resource in combination with the service requirements. For example: sending the indication information at the DRX activation time or the DTX activation time, then through this indication information, the two terminals in direct communication can achieve the configuration transformation from the active state to the inactive state; for another example: sending the indication information at the DRX inactive time or the DTX inactive time, through this indication information, the two terminals in direct communication can achieve the configuration transformation from the inactive state to the active state. Thereby reducing the latency of establishing the direct communication interface bearer and improving the user experience.

[0161] Optionally, in at least one embodiment of the present invention, step 201 includes:

[0162] When the first terminal is in the DRX inactive time or the DTX inactive time, the first terminal sends the indication information at the target position of the direct communication resource.

[0163] Further optionally, if the first terminal is in the DTX inactive time and a delay-sensitive service arrives at the direct communication interface, the first terminal sends the indication information at the target position of the direct communication resource; in this case, the indication information is used to indicate that the second terminal needs to directly enter the DRX active time, which can enable the direct communication terminal to quickly enter the DRX active time from the DRX inactive time;

[0164] It should be noted that the definitions of the active time in DRX or DTX are as follows:

[0165] The active time in DRX or DTX is the time when the terminal listens to the control channel (such as the physical sidelink control channel PSCCH of the direct communication interface) or other channels containing control information (such as the physical sidelink shared channel PSSCH containing the sidelink control information SCI of the direct communication interface), also known as the Active Time. Generally, as long as one of the following timers is running, the terminal needs to listen to the control channel or other channels containing control information:

[0166] Discontinuous reception listening timer drx-on Duration Timer;

[0167] Discontinuous reception inactivity timer drx-Inactivity Timer;

[0168] Discontinuous reception retransmission timer drx-Retransmission Timer;

[0169] Discontinuous transmission listening timer dtx-on Duration Timer;

[0170] Discontinuous transmission inactivity timer dtx-Inactivity Timer;

[0171] Discontinuous transmission retransmission timer dtx-Retransmission Timer.

[0172] In at least one embodiment of the present invention, before the first terminal sends the indication information at the target position of the direct communication resource, the first terminal needs to determine the target position. Among them, the determination methods of the target position include but are not limited to the following:

[0173] The first terminal determines the target position according to a pre-agreed protocol;

[0174] Or,

[0175] The first terminal determines the target location according to the target location indication information sent by the second terminal received through the direct communication interface. For example, the second terminal sends the target location indication information to the first terminal through the PC5-RRC reconfiguration signaling.

[0176] As an optional embodiment, before the first terminal sends the indication information at the target location of the direct communication resource, the first terminal determines the target location; wherein, the manner for the first terminal to determine the target location includes:

[0177] The first terminal determines the target location according to the terminal implementation requirements;

[0178] Or,

[0179] The first terminal determines the target location according to the radio resource control (RRC) state of the first terminal at the Uu interface.

[0180] Optionally, the first terminal determines the target location according to the radio resource control (RRC) state of the first terminal at the Uu interface, including:

[0181] If the first terminal is in the RRC connected state at the Uu interface, the first terminal determines the target location according to the target location indication information sent by the network side device received through the Uu interface; for example, the network side device sends the target location indication information to the first terminal through the Uu interface dedicated signaling.

[0182] Or,

[0183] If the first terminal is in the RRC idle state or RRC inactive state at the Uu interface, the first terminal determines the target location according to the system information block sent by the network side device received through the Uu interface, where the system information block carries the target location indication information;

[0184] Or,

[0185] If the first terminal is in the RRC off-network state at the Uu interface, the first terminal determines the target location according to the pre-configured information.

[0186] Correspondingly, as an optional embodiment, after step 201, the method further includes at least one of the following:

[0187] If the indication information indicates that the second terminal needs to directly enter the DRX activation time or DTX activation time, the first terminal starts the DRX inactive timer or DTX inactive timer corresponding to the direct communication interface;

[0188] If the indication information indicates that the second terminal needs to perform a DRX configuration change or DTX configuration change, the first terminal performs the DRX configuration change or DTX configuration change;

[0189] If the indication information indicates the identification information of the DRX configuration corresponding to the change of the DRX configuration of the second terminal or the identification information of the DTX configuration corresponding to the change of the DTX configuration of the second terminal, the first terminal changes to the DRX configuration or the DTX configuration indicated by the identification information.

[0190] In at least one embodiment of the present invention, for the sending of the "indication information", an enable (enable / disable) mechanism is introduced. After determining the enable status information (enable / disable), one end of the direct communication can notify the enable status information to its direct communication peer through the direct communication interface.

[0191] In the case of applying the enable mechanism, in at least one embodiment of the present invention, the method further includes:

[0192] When the first terminal is in the DRX active time or the DTX active time, the first terminal sends the enable status information to the second terminal through the direct communication interface;

[0193] Or,

[0194] When the first terminal is in the DRX active time or the DTX active time, the first terminal receives the enable status information sent by the second terminal through the direct communication interface;

[0195] Wherein, the enable status information is used to indicate the working state of the enable switch, and the working state of the enable switch includes: an enabled state or a disabled state.

[0196] It should be noted that when the working state of the enable switch is the enabled state, the first terminal sends the indication information at the target location, and the second terminal listens for the indication information at the target location; when the working state of the enable switch is the disabled state, the first terminal stops sending the indication information at the target location or the first terminal does not send the indication information at the target location, and the second terminal stops listening for the indication information at the target location or the second terminal does not listen for the indication information at the target location.

[0197] For example, after determining that the working state of the enable switch is the enabled state, the first terminal sends the enable status information to the second terminal, so that the second terminal also enables its enable switch when receiving the enable status information. In this way, the first terminal sends the indication information at the target location, and correspondingly, the second terminal listens for the indication information at the target location.

[0198] For another example, after the first terminal determines that the operating state of the enable switch is the disabled state, the first terminal will not send indication information at the target location. In addition, the first terminal can also send enable state information to the second terminal, so that when the second terminal receives the enable state information, its enable switch is also in the disabled state, and thus the second terminal will not listen for indication information at the target location.

[0199] Specifically, when the first terminal determines that the operating state of the enable switch is the enabled state, first, the first terminal sends the enable state information to the second terminal, and then the first terminal sends indication information at the target location. Correspondingly, the second terminal listens for indication information at the target location. After the service is executed, if the first terminal changes the operating state of the enable switch to the disabled state (it should be noted that here, the change of the enable switch state of the first terminal can be triggered by the first terminal itself or triggered by receiving the enable state information sent by the second terminal), then the first terminal does not send indication information at the target location. If the first terminal itself triggers the change of the operating state of the enable switch, the first terminal sends the enable state information to the second terminal, so that when the second terminal receives the enable state information, the operating state of its enable switch also changes to the disabled state, and then the second terminal does not listen for indication information at the target location subsequently.

[0200] For another example, when the first terminal determines that the operating state of the enable switch is the disabled state, it will not send indication information at the target location. If the first terminal determines that service processing is required or receives the status change information sent by the second terminal, the operating state of the enable switch will be changed from the prohibited state to the enabled state. If the first terminal changes the operating state of the enable switch according to the service processing requirement, it sends the enable state information to the second terminal so that the operating state of the enable switch of the second terminal is also in the enabled state. In this way, subsequently, the first terminal sends indication information at the target location, and correspondingly, the second terminal listens for indication information at the target location.

[0201] Among them, before the first terminal sends the enable state information to the second terminal through the direct communication interface, the first terminal needs to first determine the enable state information, and the determination method of the enable state information includes:

[0202] The first terminal determines the enable state information according to the terminal implementation requirements;

[0203] Or,

[0204] The first terminal determines the enable state information according to the RRC state of the first terminal at the Uu interface.

[0205] Optionally, in at least one embodiment of the present invention, the first terminal determines the enable state information according to the RRC state of the first terminal at the Uu interface, including:

[0206] If the first terminal is in the RRC connected state on the Uu interface, the first terminal obtains the enabling status information sent by the network-side device through the Uu interface; for example, the network-side device sends the corresponding enabling status information to the first terminal through the dedicated signaling on the Uu interface.

[0207] Or,

[0208] If the first terminal is in the RRC idle state or inactive state on the Uu interface, the first terminal determines the enabling status information according to the system information block sent by the network-side device received through the Uu interface; the enabling status information is carried in the system information block.

[0209] Or,

[0210] If the first terminal is in the RRC off-network state on the Uu interface, the first terminal determines the enabling status information according to the pre-configured information.

[0211] In summary, in the embodiments of the present invention, the direct communication terminal sends the indication information at the target position, and determines whether to directly enter the DRX or DTX activation time according to the indication information, or the terminal determines whether to perform a DRX or DTX configuration switch according to the indication information, so as to realize the flexible transformation of the DRX or DTX configuration, reduce the delay of establishing the direct communication interface bearer, and improve the user experience.

[0212] As Figure 4 shown, the embodiments of the present invention further provide an information indication method, and the method includes:

[0213] Step 301, the second terminal listens for the indication information sent by the first terminal at the target position of the direct communication resource.

[0214] Step 302, if the listened indication information indicates that the second terminal needs to directly enter the DRX activation time or DTX activation time, the second terminal starts the DRX inactive timer or DTX inactive timer corresponding to the direct communication interface; or, if the listened indication information indicates that the second terminal needs to perform a DRX configuration change or DTX configuration change, the second terminal performs a DRX configuration change or DTX configuration change; or, if the listened indication information indicates the identification information of the DRX configuration corresponding to the second terminal after the DRX configuration change or the identification information of the DTX configuration corresponding to the second terminal after the DTX configuration change, the second terminal changes to the DRX configuration or DTX configuration indicated by the identification information.

[0215] Wherein, the first terminal and the second terminal are terminals for direct communication.

[0216] In an embodiment of the present invention, the indication information further includes: a direct communication source address (i.e., the address of the data sending terminal) and a direct communication destination address (i.e., the address of the data receiving terminal).

[0217] In an embodiment of the present invention, through the indication of the indication information, the first terminal and the second terminal can be synchronized to enter the activation time, or the DRX configuration / DTX configuration of the first terminal and the second terminal can be synchronously changed to meet the delay requirements of different services and improve the user experience.

[0218] It should be noted that in direct communication, the first terminal can act as both a data sending terminal and a data receiving terminal; similarly, the second terminal can act as both a data receiving terminal and a data sending terminal. When the first terminal is a data sending terminal and the second terminal is a data receiving terminal, the indication information sent by the data sending terminal is used to indicate at least one of the following:

[0219] Indicating whether the second terminal needs to directly enter the discontinuous reception (DRX) activation time;

[0220] Indicating whether the second terminal needs to perform a DRX configuration change;

[0221] Indicating the identification information of the DRX configuration corresponding to the second terminal after the DRX configuration change.

[0222] When the first terminal is a data receiving terminal and the second terminal is a data sending terminal, the indication information sent by the data receiving terminal is used to indicate at least one of the following:

[0223] Indicating whether the second terminal needs to directly enter the discontinuous transmission (DTX) activation time;

[0224] Indicating whether the second terminal needs to perform a DTX configuration change;

[0225] Indicating the identification information of the DTX configuration corresponding to the second terminal after the DTX configuration change.

[0226] Optionally, in at least one embodiment of the present invention, step 301 includes:

[0227] In the case where the second terminal is in the DRX inactive time or the DTX inactive time, the second terminal listens for the indication information sent by the first terminal at the target position of the direct communication resource.

[0228] In at least one embodiment of the present invention, before the second terminal listens for the indication information sent by the first terminal at the target position of the direct communication resource, the second terminal needs to first determine the target position. The determination methods of the target position include but are not limited to the following:

[0229] The second terminal determines the target location according to a pre-agreed protocol; or,

[0230] The second terminal determines the target location according to the target location indication information sent by the first terminal received through the direct communication interface. For example, the first terminal sends the target location indication information to the second terminal through a PC5-RRC reconfiguration signaling.

[0231] As an alternative embodiment, before the second terminal listens for the indication information sent by the first terminal at the target location of the direct communication resource, the second terminal needs to first determine the target location; wherein, the ways for the second terminal to determine the target location include but are not limited to the following:

[0232] The second terminal determines the target location according to the terminal implementation requirements;

[0233] Or,

[0234] The second terminal determines the target location according to the radio resource control (RRC) state of the second terminal at the Uu interface.

[0235] Optionally, the second terminal determines the target location according to the radio resource control (RRC) state of the second terminal at the Uu interface, including:

[0236] If the second terminal is in the RRC connected state at the Uu interface, the second terminal determines the target location according to the target location indication information sent by the network-side device received through the Uu interface; for example, the network-side device sends the target location indication information to the second terminal through a dedicated Uu interface signaling;

[0237] Or,

[0238] If the second terminal is in the RRC idle state or RRC inactive state at the Uu interface, the second terminal determines the target location according to the system information block sent by the network-side device received through the Uu interface; the system information block carries the target location indication information;

[0239] Or,

[0240] If the second terminal is in the RRC off-network state at the Uu interface, the second terminal determines the target location according to the pre-configured information.

[0241] In at least one embodiment of the present invention, for the listening of "indication information", an enable / disable mechanism is introduced. After one end of the direct communication determines the enable status information (enable / disable), it can notify the enable status information to its direct communication peer through the direct communication interface.

[0242] In the case of applying the enabling mechanism, in at least one embodiment of the present invention, the method further includes:

[0243] When the second terminal is in the DRX active time or DTX active time, the second terminal sends enabling status information to the first terminal through a direct communication interface;

[0244] Or,

[0245] When the second terminal is in the DRX active time or DTX active time, the second terminal receives the enabling status information sent by the first terminal through a direct communication interface;

[0246] Wherein, the enabling status information is used to indicate the working state of an enabling switch, and the working state of the enabling switch includes: an enabled state or a disabled state.

[0247] It should be noted that when the working state of the enabling switch is the enabled state, the first terminal sends indication information at the target location, and the second terminal listens for the indication information at the target location; when the working state of the enabling switch is the disabled state, the first terminal stops sending indication information at the target location or the first terminal does not send indication information at the target location, and the second terminal stops listening for the indication information at the target location or the second terminal does not listen for the indication information at the target location.

[0248] For example, after the second terminal determines that the working state of the enabling switch is the enabled state, first, the second terminal sends the enabling status information to the first terminal, and then the first terminal sends indication information at the target location. Correspondingly, the second terminal listens for the indication information at the target location.

[0249] For another example, after the second terminal determines that the working state of the enabling switch is the disabled state, the second terminal sends the enabling status information to the first terminal; correspondingly, the first terminal does not send indication information at the target location, and the second terminal does not listen for the indication information at the target location.

[0250] For yet another example, after the second terminal determines that the working state of the enabling switch is the enabled state, first, the second terminal sends the enabling status information to the first terminal, and then the first terminal sends indication information at the target location. Correspondingly, the second terminal listens for the indication information at the target location. After the service is executed, if it is necessary to change the working state of the enabling switch to the disabled state (which can be triggered by the first terminal or the second terminal), then the second terminal sends the enabling status information to the first terminal again (the enabling status information indicates that the working state of the enabling switch is the disabled state), and then subsequently the first terminal does not send indication information at the target location, and the second terminal does not listen for the indication information at the target location.

[0251] For another example, after the second terminal determines that the operating state of the enable switch is the disabled state, the second terminal sends the enable state information to the first terminal; correspondingly, the first terminal does not send the indication information at the target location, and the second terminal does not listen for the indication information at the target location; after a period of time, if it is necessary to change the operating state of the enable switch to the enabled state (which can be triggered by the first terminal or the second terminal), the second terminal sends the enable state information to the first terminal again (the enable state information indicates that the operating state of the enable switch is the enabled state), and then the first terminal sends the indication information at the target location, and correspondingly, the second terminal listens for the indication information at the target location.

[0252] Before the second terminal sends the enable state information to the first terminal through the direct communication interface, the second terminal needs to first determine the enable state information, and the determination method of the enable state information includes:

[0253] The second terminal determines the enable state information according to the terminal implementation requirements;

[0254] Or,

[0255] The second terminal determines the enable state information according to the RRC state of the second terminal at the Uu interface.

[0256] Optionally, in at least one embodiment of the present invention, the second terminal determines the enable state information according to the RRC state of the second terminal at the Uu interface, including:

[0257] If the second terminal is in the RRC connected state at the Uu interface, the second terminal obtains the enable state information sent by the network side device through the Uu interface;

[0258] Or,

[0259] If the second terminal is in the RRC idle state or inactive state at the Uu interface, the second terminal determines the enable state information according to the system information block sent by the network side device received through the Uu interface; the enable state information is carried in the system information block;

[0260] Or,

[0261] If the second terminal is in the RRC off-network state at the Uu interface, the second terminal determines the enable state information according to the pre-configured information.

[0262] In summary, in the embodiments of the present invention, the direct communication terminal listens for indication information at the target location, and determines whether to directly enter the DRX or DTX activation time according to the indication information, or the terminal determines whether to perform DRX or DTX configuration switching according to the indication information, so as to realize flexible transformation of DRX or DTX configuration, reduce the latency of establishing the direct communication interface bearer, and improve the user experience.

[0263] To describe the information indication method provided in the embodiments of the present invention more clearly, the following will be specifically described with several examples.

[0264] Example 1, the target location is agreed by the protocol, and the information indication method is as Figure 5 shown:

[0265] Step 41, the QoS flow (Quality of Service flow) of the direct communication interface arrives;

[0266] In this step, the first terminal determines that there is a QoS flow arriving at the direct communication interface. For example, if the network side device to which the first terminal is connected schedules the first terminal to transmit the first service to the second terminal, then the QoS flow corresponding to the first service arrives at the direct communication interface of the first terminal;

[0267] Step 42, the first terminal reports the UE information of the direct communication interface to the network side device;

[0268] Optional step, if the first terminal does not store the SLRB (Sidelink Radio Bearer) configuration information corresponding to the QoS flow, the first terminal requests to obtain the SLRB configuration information corresponding to the QoS flow from the network side device to which it is connected through the UE information of the direct communication interface. For example, in the 5G NR system, the message can be Sidelink UEInformation. If the first terminal stores the SLRB corresponding to the QoS flow, skip step 42, step 43, and execute step 44;

[0269] Step 43, in response to the UE information of the direct communication interface, the network side device sends the SLRB configuration to the first terminal.

[0270] Optional step 43 is the response message of step 42. The main function of this step 43 is for the network side device to which the first terminal is connected to configure the SLRB configuration information of the direct communication interface for the first terminal.

[0271] Step 44, the first terminal sends indication information at the target location of the direct communication resource;

[0272] For example, if the first terminal is in the DRX / DTX inactive time and the newly arrived QoS flow in step 41 is a delay-sensitive service, the direct communication transmitting terminal needs to send indication information to its corresponding direct communication receiving terminal at the target location.

[0273] In this embodiment, the "target location" is agreed upon by the protocol, such as being agreed to be the starting position every 10 ms, such as the starting time slot.

[0274] Optionally, the "indication information" carries one or a combination of the following information:

[0275] Whether the second terminal needs to directly enter the DRX / DTX active time;

[0276] Whether the second terminal needs to perform DRX / DTX configuration change;

[0277] The identification information of the DRX / DTX configuration that the second terminal needs to switch to (such as the DRX / DTX configuration number).

[0278] Optionally, an enable / disable mechanism can also be introduced for the sending of the "indication information". After one end of the direct communication determines enable / disable, it can notify the enable / disable to its direct communication peer through the direct communication interface.

[0279] Step 45a, the first terminal performs the corresponding operation indicated by the indication information according to the indication information;

[0280] Step 46a, the second terminal performs the corresponding operation indicated by the indication information according to the indication information;

[0281] Step 45a and step 45b are peer operations between the first terminal and the second terminal, so as to realize the synchronization between the first terminal and the second terminal.

[0282] Taking the second terminal as an example, the corresponding operation indicated by the indication information is:

[0283] If the second terminal directly enters the DRX / DTX active time according to the indication information, further, after receiving the indication information, the second terminal needs to start the DRX / DTX inactivity timer of the direct communication interface.

[0284] If the second terminal determines according to the indication information that it needs to perform DRX / DTX configuration change, then if there are only a long DRX / DTX cycle and a short DRX / DTX cycle, the second terminal switches between the long DRX / DTX cycle and the short DRX / DTX cycle according to the indication information; if there are multiple sets of DRX / DTX cycles, the DRX / DTX configuration change can be performed according to the identification information of the DRX / DTX configuration indicated in the indication information. For example, according to the DRX / DTX configuration number carried in the indication information, the current DRX / DTX configuration is changed to the DRX / DTX configuration corresponding to the DRX / DTX configuration number.

[0285] If the second terminal determines according to the indication information that it does not need to directly enter the DRX / DTX activation time, the second terminal continues to be in the inactive time and does not perform any operations.

[0286] If the second terminal determines according to the indication information that it does not need to perform DRX / DTX configuration change, the second terminal continues to be in the inactive time and does not perform any operations.

[0287] Step 46, direct communication interface reconfiguration message;

[0288] During the nearest direct communication interface DRX / DTX activation time, the first terminal can send a PC5-RRC reconfiguration message (i.e., direct communication interface reconfiguration message) to the second terminal to configure the direct communication interface SLRB, so as to establish a direct communication interface bearer. After the direct communication interface bearer is established, data can be transmitted between the first terminal and the second terminal through the established SLRB.

[0289] Among them, the meaning of the nearest direct communication interface DRX / DRX activation time is:

[0290] If the second terminal directly enters the DRX / DTX activation time according to the indication information, the DRX / DTX activation time is the nearest direct communication interface DRX / DTX activation time;

[0291] If the second terminal switches multiple sets of DRX / DTX configurations according to the indication information, the nearest direct communication interface DRX / DTX activation time is the nearest onduration period after switching the DRX / DTX configuration.

[0292] Example 2, the target location is sent by the first terminal to the second terminal through direct communication interface signaling (such as PC5-RRC reconfiguration signaling), and the information indication method is as Figure 6 shown:

[0293] Step 50, the first terminal determines the target location and sends the target location indication information to the second terminal through the direct communication interface;

[0294] In this example, the "target location" corresponding to the indication information is sent by the first terminal to the second terminal through a direct communication interface signaling (such as a PC5-RRC reconfiguration signaling).

[0295] Specifically, there are several methods for the first terminal to determine the "target location" as follows:

[0296] 1. The first terminal determines it by itself (determined based on the implementation of the direct communication sending terminal);

[0297] 2. The determination method of the first terminal depends on the RRC state of the first terminal:

[0298] If the first terminal is in the RRC connected state, the network side device accessed by the first terminal determines the "target location", and the network side device sends it to the first terminal through a dedicated Uu interface signaling;

[0299] If the first terminal is in the RRC idle state or inactive state, the network side device accessed by the first terminal determines the "target location", and the network side device sends it to the first terminal through the SIB (System Information Block) of the Uu interface;

[0300] If the first terminal is in RRC out-of-network, the first terminal determines the "target location" according to the pre-configured information.

[0301] Step 51, the QoS flow (Quality of Service flow) of the direct communication interface arrives;

[0302] In this step, the first terminal determines that the QoS flow of the direct communication interface arrives. For example, if the network side device accessed by the first terminal schedules the first terminal to transmit the first service to the second terminal, the QoS flow corresponding to the first service arrives at the direct communication interface of the first terminal;

[0303] Step 52, the first terminal reports the UE information of the direct communication interface to the network side device;

[0304] Optional step, if the first terminal does not store the SLRB (radio bearer of the direct communication interface) configuration information corresponding to the QoS flow, the first terminal requests the network side device accessed by it to obtain the SLRB configuration information corresponding to the QoS flow through the UE information of the direct communication interface. For example, for a 5G NR system, the message can be SidelinkUEInformation. If the first terminal stores the SLRB corresponding to the QoS flow, skip step 52, step 53, and execute step 54;

[0305] Step 53: In response to the above UE information of the direct communication interface, the network-side device sends an SLRB configuration to the first terminal.

[0306] Optional step 53 is a response message to step 52. The main function of this step 53 is that the network-side device accessed by the first terminal configures the SLRB configuration information of the direct communication interface for the first terminal.

[0307] Step 54: The first terminal sends indication information at the target location of the direct communication resource;

[0308] For example, if the first terminal is in the DRX / DTX inactive time and the newly arrived QoS flow in step 51 is a delay-sensitive service, the direct communication sending terminal needs to send indication information to its corresponding direct communication receiving terminal at the target location.

[0309] The "target location" is determined according to step 50.

[0310] The "indication information" may carry one or a combination of the following information:

[0311] Whether the second terminal needs to directly enter the DRX / DTX active time;

[0312] Whether the second terminal needs to perform a DRX / DTX configuration change;

[0313] The identification information of the DRX / DTX configuration that the second terminal needs to switch to (such as the DRX / DTX configuration number).

[0314] Optionally, an enable / disable mechanism can also be introduced for the sending of the "indication information". After one end of the direct communication determines the enable / disable, it can notify the enable / disable to its direct communication peer through the direct communication interface.

[0315] Step 55a: The first terminal performs the corresponding operation indicated by the indication information according to the indication information;

[0316] Step 55a: The second terminal performs the corresponding operation indicated by the indication information according to the indication information;

[0317] Step 55a and step 55b are peer operations between the first terminal and the second terminal, so as to achieve the synchronization between the first terminal and the second terminal.

[0318] Taking the second terminal as an example, the corresponding operation indicated by the indication information is:

[0319] If the second terminal directly enters the DRX / DTX activation time according to the indication information, further, after receiving the indication information, the second terminal needs to start a direct communication interface DRX / DTX inactivity timer (drx-inactivitytimer).

[0320] If the second terminal determines according to the indication information that it needs to perform DRX / DTX configuration change, then if there are only a long DRX / DTX cycle and a short DRX / DTX cycle, the second terminal switches between the long DRX / DTX cycle and the short DRX / DTX cycle according to the indication information; if there are multiple sets of DRX / DTX cycles, the DRX / DTX configuration change can be performed according to the identification information of the DRX / DTX configuration indicated in the indication information. For example, according to the DRX / DTX configuration number carried in the indication information, the current DRX / DTX configuration is changed to the DRX / DTX configuration corresponding to the DRX / DTX configuration number.

[0321] If the second terminal determines according to the indication information that it does not need to directly enter the DRX / DTX activation time, the second terminal continues to be in the inactivity time and does not perform any operations.

[0322] If the second terminal determines according to the indication information that it does not need to perform DRX / DTX configuration change, the second terminal continues to be in the inactivity time and does not perform any operations.

[0323] Step 56, direct communication interface reconfiguration message;

[0324] During the most recent direct communication interface DRX / DTX activation time, the first terminal can send a PC5-RRC reconfiguration message to the second terminal to configure the direct communication interface SLRB, so as to realize the establishment of the direct communication interface bearer. After the establishment of the direct communication interface bearer, data can be transmitted between the first terminal and the second terminal through the established SLRB.

[0325] Among them, the meaning and example of the most recent direct communication interface DRX / DTX activation time are the same as those in Example 1 and will not be repeated here.

[0326] Example 3, the target location is sent by the second terminal to the first terminal through direct communication interface signaling (such as PC5-RRC reconfiguration signaling), and the information indication method is as Figure 7 shown:

[0327] Step 60, the second terminal determines the target location and sends the target location indication information to the first terminal through the direct communication interface;

[0328] In this example, the "target location" corresponding to the indication information is sent by the second terminal to the first terminal through direct communication interface signaling (such as PC5-RRC reconfiguration signaling);

[0329] Specifically, there are several methods for the second terminal to determine the "target location" as follows:

[0330] 1. The second terminal determines it by itself (determined based on the implementation of the direct communication sending terminal);

[0331] 2. The determination method of the second terminal depends on the RRC state of the second terminal:

[0332] If the second terminal is in the RRC connected state, the network side device to which the second terminal is connected determines the "target location", and the network side device sends it to the second terminal through the dedicated signaling of the Uu interface;

[0333] If the second terminal is in the RRC idle state or inactive state, the network side device to which the second terminal is connected determines the "target location", and the network side device sends it to the second terminal through the SIB (System Information Block) of the Uu interface;

[0334] If the second terminal is in RRC out-of-network, the second terminal determines the "target location" according to the pre-configured information.

[0335] Step 61, the QoS flow (Quality of Service flow) of the direct communication interface arrives;

[0336] In this step, the first terminal determines that the QoS flow of the direct communication interface arrives. For example, if the network side device to which the first terminal is connected schedules the first terminal to transmit the first service to the second terminal, the QoS flow corresponding to the first service arrives at the direct communication interface of the first terminal;

[0337] Step 62, the first terminal reports the UE information of the direct communication interface to the network side device;

[0338] Optional step, if the first terminal does not store the SLRB (radio bearer of the direct communication interface) configuration information corresponding to the QoS flow, the first terminal requests the network side device to which it is connected to obtain the SLRB configuration information corresponding to the QoS flow through the UE information of the direct communication interface. For example, for the 5G NR system, the message can be SidelinkUEInformation. If the first terminal stores the SLRB corresponding to the QoS flow, skip steps 62 and 63 and execute step 64;

[0339] Step 63, in response to the UE information of the direct communication interface above, the network side device sends the SLRB configuration to the first terminal.

[0340] Optional step 63 is the response message for step 62. The main function of this step 63 is that the network device accessed by the first terminal configures the SLRB configuration information of the direct communication interface for the first terminal.

[0341] Step 64, the first terminal sends indication information at the target location of the direct communication resource;

[0342] For example, if the first terminal is in the DRX / DTX inactive time and the newly arrived QoS flow in step 61 is a delay-sensitive service, the direct communication sending terminal needs to send indication information to its corresponding direct communication receiving terminal at the target location.

[0343] The "target location" is determined according to step 60.

[0344] The "indication information" may carry one or a combination of the following information:

[0345] Whether the second terminal needs to directly enter the DRX / DTX active time;

[0346] Whether the second terminal needs to perform DRX / DTX configuration change;

[0347] The identification information (such as the DRX / DTX configuration number) of the DRX / DTX configuration that the second terminal needs to switch to.

[0348] Optionally, an enable / disable mechanism can also be introduced for the sending of the "indication information". After one end of the direct communication determines enable / disable, it can notify the enable / disable to its direct communication peer through the direct communication interface.

[0349] Step 65a, the first terminal performs the corresponding operation indicated by the indication information according to the indication information;

[0350] Step 65a, the second terminal performs the corresponding operation indicated by the indication information according to the indication information;

[0351] Step 65a and step 65b are peer operations between the first terminal and the second terminal, so as to realize the synchronization between the first terminal and the second terminal.

[0352] Taking the second terminal as an example, the corresponding operation indicated by the indication information is:

[0353] If the second terminal directly enters the DRX / DTX active time according to the indication information, further, after the second terminal receives the indication information, it needs to start the DRX / DTX inactivity timer of the direct communication interface.

[0354] If the second terminal determines according to the indication information that it needs to perform DRX / DTX configuration change, then if there are only a long DRX / DTX cycle and a short DRX / DTX cycle, the second terminal switches between the long DRX / DTX cycle and the short DRX / DTX cycle according to the indication information; if there are multiple sets of DRX / DTX cycles, DRX / DTX configuration change can be performed according to the identification information of the DRX / DTX configuration indicated in the indication information. For example, according to the DRX / DTX configuration number carried in the indication information, the current DRX / DTX configuration is changed to the DRX / DTX configuration corresponding to the DRX / DTX configuration number.

[0355] If the second terminal determines according to the indication information that it does not need to directly enter the DRX / DTX activation time, the second terminal continues to be in the inactive time and does not perform any operation.

[0356] If the second terminal determines according to the indication information that it does not need to perform DRX / DTX configuration change, the second terminal continues to be in the inactive time and does not perform any operation.

[0357] Step 66, direct communication interface reconfiguration message;

[0358] During the most recent direct communication interface DRX / DTX activation time, the first terminal can send a PC5-RRC reconfiguration message to the second terminal to configure the direct communication interface SLRB, thereby realizing the establishment of the direct communication interface bearer. After the establishment of the direct communication interface bearer, data can be transmitted between the first terminal and the second terminal through the established SLRB.

[0359] Among them, the meaning and example of the most recent direct communication interface DRX / DTX activation time are the same as those in Example 1 and will not be repeated here.
