[0002] Direct communication refers to a communication method in which terminals close to each other communicate through a direct communication interface between terminals. The direct communication link between two terminals is also called a sidelink. The direct communication interface between two terminals is also called a sidelink interface. In addition, the terminal can also communicate with network equipment, and its corresponding communication link is called a Uu link, and its corresponding interface is called a Uu interface.

[0003] In order to save power of the direct communication interface, the existing mechanism introduces a discontinuous reception (DRX) and discontinuous transmission (DTX) mechanism of the direct communication interface for the direct communication interface.

[0004] However, the existing DRX and / or DTX mechanism of the direct communication interface cannot ensure that the DRX and / or DTX activation time (Active time) of the Uu interface and the SL interface are always synchronized.

[0048] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0049] It should be noted that the method and the corresponding device in the present application are based on the same application concept. Since the method and the device solve the problem in a similar manner, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0050] The technical solution provided in the embodiments of the present application can be applied to a variety of wireless communication systems.

[0051] For example, applicable systems may be global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, long term evolution advanced (LTE-A) system, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) system, 5G new radio (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0052] In order to facilitate the introduction of the technical solution of this application, the technical background involved in this application will first be briefly described:

[0053] Direct communication refers to the communication between terminals that are close to each other. The direct communication link between two terminals is also called a sidelink. The direct communication interface between two terminals is also called a sidelink interface. In addition, the terminal can also communicate with a network device, and its corresponding communication link is called a Uulink, and its corresponding interface is called a Uu interface. In order to achieve power saving of the direct communication interface, the existing mechanism introduces the DRX and DTX mechanisms of the direct communication interface for the direct communication interface.

[0054] In order to clearly understand the technical solution provided by the present application, the solution of the prior art is first introduced in detail.

[0055] Figure 1 This application provides a communication network architecture for direct communication, such as Figure 1 As shown, the communication network architecture includes at least two direct communication terminals UE1 and UE2 and network equipment, wherein the direct communication terminal UE1 can be used as a sending terminal in direct communication, and the direct communication terminal UE2 can be used as a receiving terminal in direct communication.

[0056] at the same time, Figure 1 The direct communication terminal in the present invention, also called terminal equipment, may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing equipment connected to a wireless modem, etc.

[0057] In different systems, the names of terminal devices may also be different. For example, in a 5G system, a terminal device may be called a user equipment (UE). A wireless terminal device may communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a radio access network.

[0058] For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDA) and other devices. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, and user devices, which are not limited in the embodiments of the present application.

[0059] and Figure 1 The network equipment in the network may specifically include a base station. The base station may include multiple cells that provide services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The positioning server in the network device can also coordinate the attribute management of the air interface.

[0060] like Figure 1 As shown, the direct communication terminal UE1 and the direct communication terminal UE2 use the SL interface for direct communication, while the direct communication terminal UE1 and the base station of the network device use the Uu interface for communication. Generally, the SL interface and the Uu interface each independently maintain their own DRX and / or DTX states. Therefore, there may be a situation where the DRX and / or DTX activation time (Active time) of the Uu interface and the SL interface remain asynchronous. This also means that when the network device schedules direct communication through the Uu interface, the allocated direct communication resources may fall within the DRX and / or DTX non-activation time of the direct communication interface in the time domain, resulting in the inability of the direct communication terminal to utilize the resources allocated by the network, thereby causing a waste of resources.

[0061] Specifically, Figure 2 This is a schematic diagram of scheduling signaling for direct communication in the prior art provided by the present application. Figure 2 The box area in the figure shows the signaling interaction between nodes when the direct communication interface adopts the resource allocation mode of network scheduling. First, when the direct communication sending terminal UE1 has a data transmission demand on the SL interface, UE1 sends a scheduling request (SR, Scheduling Request) for the SL interface to the base station through the Uu interface. According to the Uu DRX activation time maintenance rule, once UE1 sends the SR, UE1 will maintain the time from sending the SR to receiving the scheduling signaling of the network device on the Uu interface within the DRX activation time of the Uu interface ( Figure 2 Similarly, the network device also maintains the DRX activation time of the Uu interface during the above period to perform resource scheduling for the SL interface.

[0062] As for the SL interface, the activation status of DRX and / or DTX of the SL interface is determined based on the DRX and / or DTX related timers. When the Uu interface maintains the active time and performs resource scheduling for the SL interface, the SL interface may enter a silent period, causing the SL resources allocated by the base station to fall within the DRX and / or DTX non-activation time period of the SL interface, which can easily cause a waste of resources.

[0063] In addition, when the direct communication terminal UE1 performs buffer status reporting (BSR for short) to the network device, similar problems may also occur:

[0064] When the direct communication terminal UE1 sends a BSR to the network device, the Uu interface will be activated and enter the DRX and / or DTX activation time. The base station performs corresponding resource scheduling for the SL interface based on the received BSR. At this time, if the SL resources allocated by the base station fall within the DRX and / or DTX non-activation time period of the SL interface, it will cause resource waste.

[0065] Based on the above problems, the inventor proposes a DRX and / or DTX state maintenance method for a direct communication interface, so that after the direct communication terminal sends an SR and / or BSR for the direct communication interface to the network device, the direct communication terminal maintains the DRX and / or DTX activation time in the direct communication interface for a period of time. In this way, it can be ensured that the direct communication resources allocated by the network are always within the activation time of the direct communication interface, which is used to avoid the direct communication interface resources scheduled by the network device falling within the DRX and / or DTX non-activation time period of the direct communication interface in the time domain position, thereby avoiding the waste of direct communication interface resources.

[0066] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0067] Embodiment 1

[0068] Figure 3 A signaling diagram of a direct communication interface DRX and / or DTX state maintenance method provided in this application, such as Figure 3 As shown, the method includes:

[0069] Step 101: The direct communication sending terminal sends an SR or BSR for a direct communication interface to a network device;

[0070] Step 102: The direct communication sending terminal updates the direct communication interface DRX and / or DTX activation time.

[0071] Step 103: The direct communication sending terminal sends instruction information to the direct communication receiving terminal.

[0072] Step 104: The direct communication receiving terminal updates the direct communication interface DRX and / or DTX activation time according to the indication information.

[0073] Step 105: The direct communication sending terminal receives, at the Uu interface, a scheduling signaling for the direct communication interface sent by the network device.

[0074] Step 106: The direct communication sending terminal sends a direct communication interface scheduling signaling to the direct communication receiving terminal on the direct communication interface.

[0075] It should be noted that in Figure 3 In the signaling shown, the direct communication sending terminal UE1 and the direct communication receiving terminal UE2 perform direct communication via the direct communication interface SL, and the direct communication sending terminal UE1 performs cellular communication with the network device via the Uu interface.

[0076] In the actual communication process, the execution order of step 101 and step 103 will not be restricted. Figure 3 As shown, first execute step 101, then execute step 103 ( Figure 3 The execution order shown in FIG. 100 is as follows); step 103 may be executed first, and then step 101 ( Figure 3 Not shown); Step 101 and step 103 may also be executed simultaneously ( Figure 3 (not shown).

[0077] In addition, for step 102 and step 103, although Figure 3The timing between step 102 and step 103 is shown (step 102 is executed first and then step 103), but in the actual communication process, there is no correlation in the execution timing between step 102 and step 103. Figure 3 The timing of step 102 and step 103 shown does not impose any limitation on the present technical solution.

[0078] Specifically, during the communication process, after the network device receives the SR and / or BSR for the direct communication interface initiated by the direct communication sending terminal UE1 to the network device, its Uu interface will remain within the DRX and / or DTX activation time. At this time, the network device will send scheduling signaling for the direct communication interface to the direct communication terminal UE1 through the Uu interface.

[0079] Figure 4 A flow chart of a direct communication interface DRX and / or DTX state maintenance method provided by the present application, wherein the Figure 4 The execution subject of the process is the direct communication sending terminal.

[0080] Combination Figure 3 and Figure 4 It can be seen that, based on network requirements, as shown in step 101, the direct communication sending terminal UE1 may send a scheduling request (Scheduling Request, referred to as SR) for the direct communication interface SL interface and / or a buffer state report (Buffer state report, referred to as BSR) to the network device. Among them, the triggering condition for the direct communication sending terminal UE1 to send SR and BSR may be specifically based on the existing protocol, and this embodiment does not impose any restrictions on its triggering condition.

[0081] As shown in step 102, after the direct communication sending terminal UE1 sends the SR and / or BSR for the direct communication interface SL interface to the network device, the direct communication sending terminal UE1 updates the DRX and / or DTX activation time of the direct communication interface so that the direct communication sending terminal UE1 is in the DRX and / or DTX activation time at the direct communication interface within a first preset time period.

[0082] Among them, the starting time of the first preset time period is the sending time of the SR or the BSR; the ending time of the first preset time period is the receiving time of the scheduling signaling for the direct communication interface sent by the network device by the direct communication sending terminal UE1, or the time when the direct communication sending terminal UE1 sends the direct communication interface control information SCI to the direct communication receiving terminal UE2 through the direct communication interface.

[0083] That is, as an optional implementation, the direct communication sending terminal UE1 needs to maintain the DRX and / or DTX activation time on the direct communication interface during a first preset period. The first preset period may be one of the following periods:

[0084] (1) a period from when the direct communication sending terminal UE1 sends an SR / BSR to when the direct communication sending terminal UE1 receives a scheduling signaling for the direct communication interface sent by the network device;

[0085] (2) A period from after the direct communication terminal UE1 sends the SR / BSR to before the direct communication transmitting terminal UE1 sends the direct communication interface control information SCI to the direct communication receiving terminal UE2 via the direct communication interface.

[0086] Among them, optionally, the direct communication sending terminal sends the direct communication interface control information SCI to the direct communication receiving terminal through the direct communication interface, which may be the second-stage SCI. Currently, the direct communication interface SCI includes two parts, the first-stage SCI (stage-1 SCI) is used to transmit time / frequency domain resource indication information, and the second-stage SCI (stage-2 SCI) is used to carry information such as the direct communication source identifier and the target identifier.

[0087] As an optional implementation manner, when the direct communication sending terminal UE1 updates the activation state of the DRX and / or DTX of the direct communication interface, one of the following methods may be specifically adopted:

[0088] One is: when or after the direct communication sending terminal UE1 sends an SR or BSR for the direct communication interface to the network device, the first timer is started, so that during the operation of the first timer, the direct communication sending terminal UE1 is in the activation time of DRX and / or DTX at the direct communication interface.

[0089] The time length of the first timer may be configured by the network, or agreed upon through a protocol.

[0090] Furthermore, the first timer is a direct communication interface DRX and / or DTX inactivity timer.

[0091] The second is: the protocol stipulates that the time period between when the direct communication sending terminal sends the SR and / or BSR for the direct communication interface to the network device and receives the scheduling signaling for the direct communication interface from the network device is the direct communication interface DRX and / or DTX activation time.

[0092] As shown in step 103, in order to ensure that the direct communication receiving terminal UE2 also maintains the DRX / DRX activation time at the direct communication interface before receiving the direct communication interface scheduling signaling SCI sent by the direct communication sending terminal UE1 for the direct communication interface (that is, UE2 ensures the DRX / DRX activation time at the direct communication interface before step 106), the direct communication sending terminal UE1 will also send an indication information to the direct communication receiving terminal UE2, and the indication information will be used to instruct the direct communication receiving terminal UE2 to maintain the DRX and / or DTX activation time during the second preset time period.

[0093] That is, the direct communication sending terminal UE1 sends indication information to the direct communication receiving terminal UE2 through the direct communication interface, so that the direct communication receiving terminal UE2 updates the DRX and / or DTX activation time of the direct communication interface according to the indication information, so that the direct communication receiving terminal UE2 is in the DRX and / or DTX activation time at the direct communication interface within the second preset time period;

[0094] The second preset time period at least includes the moment when the direct communication receiving terminal UE2 receives the direct communication interface control information SCI sent by the direct communication sending terminal UE1 through the direct communication interface.

[0095] Take the time T when the direct communication sending terminal UE1 sends the indication information to the direct communication receiving terminal UE2 in step 103 as an example:

[0096] The above-mentioned time T (the time when the direct communication sending terminal UE1 sends the instruction information to the direct communication interface to the direct communication receiving terminal UE2) may be one of the following times:

[0097] (1) The time T at which the direct communication sending terminal sends the indication information to the direct communication receiving terminal through the direct communication interface is the time at which the direct communication sending terminal sends the scheduling request SR or the buffer status report BSR.

[0098] (2) The time T at which the direct communication sending terminal sends the indication information to the direct communication receiving terminal through the direct communication interface is before the time at which the direct communication sending terminal sends the scheduling request SR or the buffer status report BSR.

[0099] The difference between the time when the direct communication sending terminal sends the indication information to the direct communication receiving terminal through the direct communication interface and the time when the direct communication sending terminal sends the scheduling request SR or the buffer status report BSR is less than the first time threshold.

[0100] (3) The time T at which the direct communication sending terminal sends the indication information to the direct communication receiving terminal through the direct communication interface is after the time at which the direct communication sending terminal sends the scheduling request SR or the buffer status report BSR.

[0101] Among them, the time when the direct communication sending terminal sends the indication information to the direct communication receiving terminal through the direct communication interface is the same as the time when the direct communication sending terminal sends the scheduling request SR or the cache status report BSR, and the difference between the two is less than the second time threshold.

[0102] For the first time threshold and the second time threshold mentioned above, this implementation does not restrict the magnitude relationship between the two, and their respective specific values ​​can be determined according to actual conditions.

[0103] As an optional implementation manner, the indication information in step 103 is sent by the direct communication sending terminal UE1 to the direct communication receiving terminal UE2 through physical layer signaling or high layer signaling.

[0104] In which, when the indication information is sent by the direct communication sending terminal to the direct communication receiving terminal through physical layer signaling, the indication information is sent through the direct communication interface control information SCI, and the SCI does not include direct communication resource scheduling information, which is only used to extend the direct communication receiving terminal's DRX and / or DTX activation time in the direct communication interface.

[0105] When the indication information is sent by the direct communication sending terminal to the direct communication receiving terminal through high-layer signaling, the indication information can be sent specifically through MACCE or RRC signaling based on high-layer signaling; in addition, the high-layer signaling can be a newly introduced signaling, or it can be an IE added to the existing signaling, and this application does not limit it.

[0106] As an optional implementation manner, in order to ensure that the indication information can be effectively sent to the direct communication receiving terminal, the indication information is sent by the direct communication sending terminal during the DRX and / or DTX activation time of the direct communication interface.

[0107] As an optional implementation, in order to save signaling overhead, the triggering condition for sending the indication information is that the direct communication sending terminal predicts that the direct communication receiving terminal will enter a DRX and / or DTX silent period before receiving the SCI.

[0108] Among them, whether the direct communication receiving terminal UE2 enters the DRX and / or DTX silent period can be determined by the running status of the timer related to its direct communication interface DRX and / or DTX. For example, when the relevant timer is in a non-running state, the direct communication receiving terminal UE2 is in the direct communication interface DRX and / or DTX silent period.

[0109] Figure 5 A flowchart of another direct communication interface DRX and / or DTX state maintenance method provided by the present application, wherein the Figure 5 The execution subject of the process is the direct communication receiving terminal.

[0110] Combination Figure 3 and Figure 5 , when the direct communication sending terminal UE1 sends the indication information to the direct communication receiving terminal UE2, that is, after the direct communication receiving terminal UE2 receives the indication information sent by the direct communication sending terminal UE1, as shown in step 104, the direct communication receiving terminal UE2 updates the direct communication interface DRX and / or DTX activation time, so that the direct communication receiving terminal UE2 is in the DRX and / or DTX activation time at the direct communication interface within the second preset time period. The second preset time period at least includes the moment when the direct communication receiving terminal UE2 receives the direct communication interface control information SCI sent by the direct communication sending terminal UE1 through the direct communication interface.

[0111] As an optional implementation, the direct communication interface control information SCI sent by the direct communication sending terminal and received by the direct communication receiving terminal through the direct communication interface is the SCI of the second stage. Similar to the SCI in the aforementioned implementation, the current direct communication interface SCI includes two parts, the first stage SCI (stage-1 SCI) is used to transmit time / frequency domain resource indication information, and the second stage SCI (stage-2 SCI) is used to carry information such as the direct communication source identifier and the target identifier.

[0112] As an optional implementation manner, the direct communication receiving terminal UE2 updates the activation time of the DRX and / or DTX of the direct communication interface according to the indication information, and specifically one of the following methods may be adopted:

[0113] One is: the direct communication receiving terminal UE2 starts a third timer while or after receiving the indication information, so that during the operation of the third timer, the direct communication receiving terminal UE2 is in the activation time of DRX and / or DTX of the direct communication interface. The time length of the third timer can be configured by the network, or agreed upon through a protocol.

[0114] Furthermore, the third timer is a direct communication interface DRX and / or DTX inactivity timer.

[0115] The second is: the protocol stipulates that the time period between when the direct communication receiving terminal receives the indication information and when the direct communication receiving terminal receives the scheduling signaling of the direct communication interface sent by the direct communication sending terminal is the direct communication interface DRX and / or DTX activation time.

[0116] Through the above-mentioned steps 101 to 104, the direct communication interface will be at the DRX and / or DTX activation time. At this time, as shown in steps 105 and 106, the direct communication sending terminal UE1 receives the scheduling signaling for the direct communication interface sent by the network device at the Uu interface, and then the direct communication sending terminal UE1 will send the direct communication interface scheduling signaling to the direct communication receiving terminal UE2 based on the scheduling signaling.

[0117] The direct communication interface scheduling signaling sent by the direct communication sending terminal UE1 to the direct communication receiving terminal UE2 is specifically based on the SCI, and the content of the SCI is determined based on the scheduling signaling initiated by the network device received by the direct communication sending terminal UE1.

[0118] The above-mentioned embodiment 1 provides a method for maintaining the DRX and / or DTX status of a direct communication interface, which is achieved by, after the direct communication sending terminal sends an SR or BSR for the direct communication interface to the network device, the direct communication sending terminal updates the activation time of the DRX and / or DTX of the direct communication interface, and the direct communication receiving terminal updates the activation time of the DRX and / or DTX of the direct communication interface, so that when the direct communication sending terminal receives the resources sent by the network device, it can communicate with the direct communication receiving terminal through the direct communication interface in the DRX and / or DTX activation time, thereby avoiding the direct communication interface resources scheduled by the network device from falling within the DRX and / or DTX non-activation time period of the direct communication interface in the time domain, thereby avoiding waste of direct communication interface resources.

[0119] Embodiment 2

[0120] Based on Example 1, Figure 6 A signaling diagram of another direct communication interface DRX and / or DTX state maintenance method provided by the present application, such as Figure 6 As shown, the method includes:

[0121] Step 201: The direct communication sending terminal sends an SR or BSR for a direct communication interface to a network device.

[0122] Step 202: The direct communication sending terminal updates the direct communication interface DRX and / or DTX activation time.

[0123] Step 203: The direct communication sending terminal sends instruction information to the direct communication receiving terminal;

[0124] Step 204: The direct communication sending terminal updates the direct communication interface DRX and / or DTX activation time according to the indication information.

[0125] Step 205: The direct communication receiving terminal receives the indication information and updates the direct communication interface DRX and / or DTX activation time.

[0126] Step 206: The direct communication sending terminal receives, at the Uu interface, a scheduling signaling for the direct communication interface sent by the network device.

[0127] Step 207: The direct communication sending terminal sends a direct communication interface scheduling signaling to the direct communication receiving terminal on the direct communication interface.

[0128] It should be noted that, similar to the first embodiment, Figure 6 In the signaling shown, the direct communication sending terminal UE1 and the direct communication receiving terminal UE2 perform direct communication via the direct communication interface SL, and the direct communication sending terminal UE1 performs cellular communication with the network device via the Uu interface.

[0129] in, Figure 6 In step 201 and step 203, the order of execution of the steps may be to first execute step 201, then execute step 203 (e.g. Figure 6 As shown); it is also possible to first execute step 203 and then execute step 201 ( Figure 6 Not shown); Step 201 and step 203 may also be executed simultaneously ( Figure 6 (not shown).

[0130] In addition, for step 202 and step 203, although Figure 6 The timing between step 202 and step 203 is shown (step 202 is executed first and then step 203), but in the actual communication process, there is no correlation in the execution timing between step 202 and step 203. Figure 6 The timing of step 202 and step 203 shown does not impose any limitation on the present technical solution.

[0131] In the second embodiment, steps 201, 202, 203, 205, 206 and 207 are similar to steps 101, 102, 103, 104, 105 and 106 in the first embodiment, and are not described in detail in this embodiment.

[0132] What is different from the first embodiment is that in step 204 of this embodiment, the direct communication sending terminal UE1 not only updates the DRX and / or DTX activation time of the direct communication interface after sending the SR or BSR for the direct communication interface to the network device, so that the direct communication sending terminal UE1 updates the direct communication interface DRX and / or DTX activation time when the direct communication interface is in the DRX and / or DTX activation time within the first preset time period, but also sends indication information from the direct communication sending terminal UE1 to the direct communication receiving terminal UE2, and updates the direct communication interface DRX and / or DTX activation time according to the indication information.

[0133] Figure 7 A flow chart of a direct communication interface DRX and / or DTX state maintenance method provided by the present application, wherein the Figure 7 The execution subject of the process is the direct communication sending terminal.

[0134] Combination Figure 6 and Figure 7 As shown, the direct communication sending terminal UE1 sends indication information to the direct communication receiving terminal UE2 through the direct communication interface, and the direct communication sending terminal UE1 updates the DRX and / or DTX activation time of the direct communication interface so that the direct communication sending terminal UE1 is in the DRX and / or DTX activation time of the direct communication interface within the first preset time period.

[0135] Among them, the first preset time period is similar to that described in the aforementioned embodiment 1, that is, the starting time of the first preset time period is the sending time of the SR or the BSR; the end time of the first preset time period is the receiving time of the direct communication sending terminal receiving the scheduling signaling sent by the network device for the direct communication interface, or, the time when the direct communication sending terminal sends direct communication interface control information SCI to the direct communication receiving terminal through the direct communication interface.

[0136] In an optional implementation manner, after the direct communication sending terminal UE1 sends the indication information to the direct communication receiving terminal UE2, the direct communication sending terminal UE1 updates the activation time of the DRX and / or DTX of the direct communication interface, and the specific manner may include one of the following:

[0137] One is: the direct communication sending terminal UE1 starts a second timer at the same time or after sending the indication information, so that during the operation of the second timer, the direct communication sending terminal is in the activation time of DRX and / or DTX at the direct communication interface. The time length of the second timer can be configured by the network, or agreed upon through a protocol.

[0138] In a further optional implementation manner, the second timer is a direct communication interface DRX and / or DTX inactivity timer.

[0139] The second is: it is agreed in the protocol that the time period between the direct communication sending terminal sending indication information to the direct communication receiving terminal and the direct communication sending terminal sending SCI to the direct communication receiving terminal is the direct communication interface DRX and / or DTX activation time.

[0140] The above-mentioned embodiment 2 provides a method for maintaining the DRX and / or DTX status of a direct communication interface, which is achieved by, after the direct communication sending terminal sends an SR or BSR for the direct communication interface to the network device, the direct communication sending terminal updates the activation time of the DRX and / or DTX of the direct communication interface, and the direct communication receiving terminal updates the activation time of the DRX and / or DTX of the direct communication interface, so that when the direct communication sending terminal receives the resources sent by the network device, it can communicate with the direct communication receiving terminal through the direct communication interface in the DRX and / or DTX activation time, thereby avoiding the direct communication interface resources scheduled by the network device from falling within the DRX and / or DTX non-activation time period of the direct communication interface in the time domain, thereby avoiding waste of direct communication interface resources.
