[0054] As shown in Figure 1 The terminals 11 can perform direct data transmission through a sidelink (also referred to as a side link, a side chain, a side link, etc.). The present application provides a configuration method of SL DTX applied between terminals.

[0055] With reference to the accompanying drawings, the configuration method, device and related equipment of SL DRX provided by embodiments of the present application will be described in detail through some embodiments and application scenarios.

[0056] Please refer to Figure 2 , Figure 2 is one of the flowcharts of the SL DRX configuration method provided by embodiments of the present application, and the method is applied to a first terminal. As shown in Figure 2 , the method comprises the following steps:

[0057] Step 201: The first terminal receives SL DRX configuration information sent by a second terminal.

[0058] It should be noted that the first terminal and the second terminal are not specific terminals. In some scenarios, the first terminal can act as a receiver, and the second terminal can act as a sender. In other scenarios, the first terminal can also act as a sender, and the second terminal can act as a receiver.

[0059] In the implementation scenarios of embodiments of the present application, the first terminal is taken as the receiver of SL unicast service, i.e., the receiver of SL DRX configuration, and the second terminal is taken as the sender of SL unicast service, i.e., the sender of SL DRX configuration. The technical solutions of embodiments of the present application will be described in detail.

[0060] Optionally, the SL DRX configuration information sent by the second terminal can include parameters such as onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, longDRX-CycleStartOffset, etc.

[0061] Step 202: The first terminal sends target information to the second terminal under the condition that a first condition is met, and the target information is used for negotiation of the SL DRX configuration information.

[0062] The first condition comprises at least one of the following:

[0063] The time when the first terminal sends the target information is within a first timing time;

[0064] The number of times when the first terminal sends the target information is within a first preset number of times;

[0065] The first terminal is allowed to send the target information.

[0066] It should be noted that, for the first terminal, that is, the receiving party, the target information is used for negotiation of the SL DRX configuration information, for example, can be information including a rejection of the SL DRX configuration information and / or related operations for assisting the sender to send new SL DRX configuration information, for example, the target information includes SL DRX configuration rejection information and / or SL DRX configuration assistance information; for the second terminal, that is, the sender, the second terminal can perform related operations of SL DRX reconfiguration according to the target information, for example, send updated SL DRX configuration information.

[0067] In the embodiment of the application, the first terminal, in the case of receiving the SL DRX configuration information sent by the second terminal, judges whether a first condition for SL DRX configuration negotiation is met, and in the case of meeting the first condition, sends target information for negotiation of the SL DRX configuration information to the second terminal.

[0068] For example, the first condition includes that the time when the first terminal sends the target information is within a first timing time, that is, when the time when the first terminal sends the target information is within the first timing time, the first terminal sends the target information to the second terminal. Alternatively, the first condition includes that the first terminal is allowed to send the target information, that is, the first terminal sends the target information to the second terminal in the case of being allowed to send the target information. Of course, the first condition can also include other possible cases, which will not be enumerated one by one in this embodiment.

[0069] In the embodiment of the application, in the case where the first condition includes that the time when the first terminal sends the target information is within the first timing time, the method further includes:

[0070] The first terminal judges whether the time when the target information is sent is within the first timing time by a first timer;

[0071] The starting time of the first timer is when the first terminal receives the SL DRX configuration information for the first time; or,

[0072] In the case where the first terminal is not sending the target information for the first time, the starting time of the first timer is when the first terminal sends the target information for the first time.

[0073] It should be noted that the first terminal can be configured with a first timer, and the first timer can be started when the first terminal receives the SL DRX configuration information sent by the sender for the first time, or the first timer is started when the first terminal sends the target information for the first time in the case that the first terminal is not sending the target information for the first time. For example, for the case that the first terminal sends the target information multiple times, when the first terminal sends the target information for the first time, it can be determined whether the time of sending the target information is within the first timing time without the first timer, for example, if the first terminal is allowed to send the target information, the first terminal sends the target information and starts the first timer at the same time, and when the first terminal sends the target information again, it can be determined whether the time of sending the target information is within the first timing time by using the first timer to determine whether to send the target information.

[0074] In the embodiments of the present application, if the first terminal plans to send the target information to the second terminal, and the time of sending the target information by the first terminal is within the first timing time, the first terminal sends the target information to the second terminal at the time. If the time of sending the target information by the first terminal exceeds the first timing time, the first terminal does not send or is not allowed to send the target information.

[0075] Optionally, the number of the first timers is one or more; in the case that only one first timer is configured, the first timer is configured with a timing duration corresponding to each terminal; in the case that at least two first timers are configured, one first timer is configured with a timing duration corresponding to each unicast link or a group of Quality of Service (QoS) attributes.

[0076] For example, if the first timer is configured with one for a terminal, the first timer is configured with a timing duration corresponding to each terminal; if the first timer is configured with two or more for a terminal, the first timer is configured with a timing duration corresponding to each unicast link or a group of QoS attributes of the terminal. It should be noted that the final time of the timing duration of the configured first timer can be the final time of the first timing time.

[0077] Optionally, the first timer satisfies at least one of the following: configured by a network side device, preconfigured, configured by the second terminal.

[0078] In the embodiments of the present application, in the case that the first condition includes that the number of times of sending the target information by the first terminal is within a first preset number of times, the method further includes:

[0079] The first terminal judges whether the number of times of sending the target information is within a first preset number of times through a first counter, and the first counter is incremented by one each time the target information is sent.

[0080] Optionally, the first terminal is configured with a first counter and a maximum count value of the first counter, and an initial count value of the first counter is configured as 0, and the count value of the first counter is incremented by one each time the target information is sent.

[0081] Optionally, if the first terminal plans to send the target information to the second terminal, and the number of times of sending the target information by the first terminal is less than the first preset number of times, the first terminal sends the target information to the second terminal; for example, the first preset number of times is 5, and the number of times of sending the target information by the first terminal is the third time, that is, the target information has been sent twice, and the number of times of sending the target information by the first terminal is within the first preset number of times, so the first terminal can send the target information this time. If the number of times of sending the target information by the first terminal is greater than the first preset number of times, the first terminal does not send or is not allowed to send the target information.

[0082] Optionally, the number of the first counters is one or more; in the case of configuring only one first counter, the maximum count value of the first counter is configured for each terminal; in the case of configuring at least two first counters, the maximum count value of one first counter is configured for each unicast link or a group of QoS attributes.

[0083] For example, if the first counter is configured for one terminal, the maximum count value of the first counter is configured for each terminal; if the first counter is configured for two or more terminals, the maximum count value of one first counter is configured for each unicast link (link) or a group of QoS attributes of the terminal. It should be noted that the maximum count value of the configured first counter can be the first preset number of times.

[0084] Optionally, the first counter satisfies at least one of the following: configured by a network side device, preconfigured, configured by the second terminal.

[0085] Optionally, in the case where the first condition includes that the first terminal is allowed to send the target information, the method further comprises:

[0086] The first terminal judges whether it is allowed to send the target information through at least one of the following: configuration indication information of a network side device, pre-configuration indication information, configuration indication information of the second terminal, and protocol agreement.

[0087] In an embodiment of the present application, the target information includes at least one of the following: SL DRX configuration assistance information, SL DRX configuration rejection information; wherein the SL DRX configuration assistance information is used to assist the second terminal to configure updated SL DRX configuration information; and the SL DRX configuration rejection information is used to reject the SL DRX configuration information.

[0088] For example, the target information includes SL DRX configuration rejection information, that is, after receiving the SL DRX configuration information sent by the second terminal, if the configuration parameters included in the SL DRX configuration information are not applicable to the first terminal, or the first terminal does not accept the SL DRX configuration information sent by the second terminal, the first terminal can send SL DRX configuration rejection information to the second terminal to reject the SL DRX configuration of the second terminal.

[0089] Alternatively, after receiving the SL DRX configuration information sent by the second terminal, if the configuration parameters included in the SL DRX configuration information are not applicable to the first terminal, or the first terminal does not accept the SL DRX configuration information currently sent by the second terminal, the first terminal can also send SL DRX configuration assistance information to the second terminal to assist the second terminal to configure updated SL DRX configuration information. For example, the SL DRX configuration assistance information can include information indicating the SL DRX configuration parameters applicable to the first terminal. In this way, the second terminal can configure updated SL DRX configuration information based on the SL DRX configuration assistance information, so as to ensure that the first terminal can accept the updated SL DRX configuration information, avoid endless SL DRX rejection and SL DRX reconfiguration between the first terminal and the second terminal, simplify the SL DRX configuration process between terminals, and improve the efficiency of the terminal SL DRX configuration process.

[0090] Optionally, in the case where the target information includes SL DRX configuration assistance information and SL DRX configuration rejection information, the SL DRX configuration assistance information and the SL DRX configuration rejection information satisfy any one of the following:

[0091] The SL DRX configuration assistance information and the SL DRX configuration rejection information are carried in the SL radio resource control (Radio Resource Control, RRC) reconfiguration complete message;

[0092] The SL DRX configuration assistance information and the SL DRX configuration rejection information are carried in the SL RRC reconfiguration failure message;

[0093] The SL DRX configuration rejection information is carried in an SL RRC reconfiguration complete message, and the SL DRX configuration assistance information is carried in an SL terminal assistance information (UE Assistance Information, UAI).

[0094] The SL DRX configuration rejection information is carried in an SL RRC reconfiguration failure message, and the SL DRX configuration assistance information is carried in an SL UAI.

[0095] It should be noted that the SL DRX configuration of the second terminal to the first terminal can occur in an SL RRC reconfiguration complete process, in which case, if the first terminal does not accept the SL DRX configuration information sent by the second terminal, the SL DRX configuration assistance information and the SL DRX configuration rejection information sent by the first terminal to the second terminal can be carried in an SL RRC reconfiguration complete message, or the SL DRX configuration rejection information is carried in an SL RRC reconfiguration complete message, and the SL DRX configuration assistance information is carried in an SL UAI.

[0096] Alternatively, the SL DRX configuration of the second terminal to the first terminal can occur in an SL RRC reconfiguration failure process, in which case, if the first terminal does not accept the SL DRX configuration information sent by the second terminal, the SL DRX configuration assistance information and the SL DRX configuration rejection information sent by the first terminal to the second terminal can be carried in an SL RRC reconfiguration failure message, or the SL DRX configuration rejection information is carried in an SL RRC reconfiguration failure message, and the SL DRX configuration assistance information is carried in an SL UAI.

[0097] Optionally, in the case where the target information only includes SL DRX configuration rejection information, the target information is carried in any one of the following:

[0098] an SL RRC reconfiguration complete message;

[0099] an SL RRC reconfiguration failure message.

[0100] The scheme provided in the embodiments of the present application is that, in the case that the first terminal receives the SL DRX configuration information sent by the second terminal, the first terminal judges whether the first terminal satisfies the first condition, and if the first terminal satisfies the first condition, the first terminal sends target information to the second terminal for negotiation of the SL DRX configuration information, and further makes the second terminal stop the SL DRX configuration based on the target information or configure updated SL DRX configuration information based on the target information, so that the first terminal can receive the updated SL DRX configuration information. In this way, by the agreed first condition, the sending behavior of the SL DRX configuration information between terminals can be regulated, endless SL DRX rejection and SL DRX reconfiguration between terminals can be avoided, the SL DRX configuration process between terminals can be simplified, the SL DRX process efficiency of the terminal can be improved, and the energy consumption of the terminal can be saved.

[0101] In the embodiments of the present application, the method further includes:

[0102] In the case that the first terminal does not satisfy the first condition, the first terminal accepts the SL DRX configuration of the second terminal based on the SL DRX configuration information.

[0103] It can be understood that, after the first terminal receives the SL DRX configuration information sent by the second terminal, if the first terminal does not satisfy the first condition, for example, the first terminal is not allowed to send the target information, or the number of times that the first terminal sends the target information exceeds the first preset number of times, or the time at which the first terminal sends the target information is outside the first timing time, the first terminal accepts the SL DRX configuration of the second terminal based on the SL DRX configuration information.

[0104] Optionally, after the first terminal accepts the SL DRX configuration of the second terminal based on the SL DRX configuration information in the case that the first terminal does not satisfy the first condition, the method further includes:

[0105] The first terminal sends an SL RRC reconfiguration complete message to the second terminal, and the SL RRC reconfiguration complete message does not include SL DRX configuration rejection information.

[0106] It should be noted that, after the first terminal accepts the SL DRX configuration of the second terminal, the first terminal can send an SL RRC reconfiguration complete message to the second terminal, so as to notify the second terminal that the first terminal has accepted the SL DRX configuration of the second terminal, and the second terminal can be prevented from continuing to send SL DRX configuration information, so as to save the energy consumption of the terminal.

[0107] In the embodiments of the present application, after the first terminal sends the target information to the second terminal under the condition of meeting the first condition, the method further includes:

[0108] The first terminal receives the updated SL DRX configuration information sent by the second terminal.

[0109] It can be understood that the target information includes SL DRX configuration assistance information and / or SL DRX configuration rejection information, and the second terminal can know that the first terminal does not accept the previously sent SL DRX configuration information based on the target information, so that the second terminal can update the SL DRX configuration information and send the updated SL DRX configuration information to the first terminal. Wherein, in the case that the target information includes SL DRX configuration assistance information, the second terminal can update the SL DRX configuration information based on the SL DRX configuration assistance information to ensure that the updated SL DRX configuration information can be accepted by the first terminal, so as to improve the efficiency of the inter-terminal SL DRX configuration process.

[0110] Optionally, before the second terminal sends the updated SL DRX configuration information to the first terminal, the second terminal can further determine whether the second terminal meets the second condition, and the second terminal sends the updated SL DRX configuration information to the first terminal only under the condition of meeting the second condition. Wherein, the second condition includes at least one of the following:

[0111] The second terminal receives the target information sent by the first terminal, and the target information is used for negotiation of the SL DRX configuration information;

[0112] The time when the second terminal sends the updated SL DRX configuration information is within a second timing time;

[0113] The number of times that the second terminal sends the updated SL DRX configuration information is within a second preset number of times;

[0114] The second terminal is allowed to initiate SL DRX reconfiguration.

[0115] The specific implementation of the above second condition will be described in subsequent embodiments, and this embodiment will not be described in detail.

[0116] In an embodiment of the embodiment of the present application, the first terminal receives the SL DRX configuration information sent by the second terminal, including:

[0117] The first terminal receives the SL DRX configuration information and SL radio bearer (Radio Bearer, RB) configuration information sent by the second terminal.

[0118] Optionally, in this embodiment, if the second terminal configures the first terminal's SL DRX in the SL RRC reconfiguration complete procedure, the target information sent by the first terminal is carried in the SL RRC reconfiguration complete message, and after the step of the first terminal sending the target information to the second terminal, the method further comprises at least one of the following:

[0119] In the case that the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the transmission state between the first terminal and the second terminal is the SL DRX off state or the non-SL DRX state.

[0120] The first terminal validates the SL RB configuration information.

[0121] For example, after the first terminal sends the SL DRX configuration assistance information and / or the SL DRX configuration rejection information to the second terminal, if the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, for example, the second terminal does not meet the second condition, the second terminal will not send the updated SL DRX configuration information, and by default, the transmission state between the first terminal and the second terminal is the SL DRX off state, or the transmission between the first terminal and the second terminal is the non-SL DRX state, that is, the first terminal and the second terminal exit the SL DRX procedure to save terminal energy consumption.

[0122] Alternatively, in the case that the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the first terminal can also validate the SL RB configuration information sent by the second terminal.

[0123] Alternatively, in the case that the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the transmission state between the first terminal and the second terminal is the SL DRX off state, and the first terminal validates the SL RB configuration information sent by the second terminal.

[0124] Optionally, the second terminal can also configure the first terminal's SL DRX in the SL RRC reconfiguration failure procedure, and in this scenario, the target information is carried in the SL RRC reconfiguration failure message, and after the step of the first terminal sending the target information to the second terminal, the method further comprises at least one of the following:

[0125] In the case that the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the transmission state between the first terminal and the second terminal is the SL DRX off state or the non-SL DRX state.

[0126] The first terminal receives the SL RB configuration information re-sent by the second terminal.

[0127] In a case where the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, for example, the second terminal does not meet the second condition, the second terminal does not send the updated SL DRX configuration information to the first terminal, and the transmission state between the first terminal and the second terminal is by default in the SL DRX sleep state.

[0128] Alternatively, in a case where the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the second terminal re-sends the SL RB configuration information to the first terminal, and the first terminal can activate the re-sent SL RB configuration information or not.

[0129] Alternatively, in a case where the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the transmission state between the first terminal and the second terminal is by default in the SL DRX sleep state, and the second terminal re-sends the SL RB configuration information to the first terminal.

[0130] Optionally, the SL RB configuration information is carried in an SL RRC reconfiguration message sent by the second terminal, and after the first terminal receives the SL RB configuration information re-sent by the second terminal, the method further includes:

[0133] In the embodiments of the present application, in a case where the second terminal receives the target information sent by the first terminal and does not send the updated SL DRX configuration information to the first terminal, the second terminal can send a new SL RRC reconfiguration message carrying the SL RB configuration information, the first terminal performs an SL RRC reconfiguration process based on the SL RRC reconfiguration message, in a case where the SL RRC reconfiguration process is successful, the first terminal sends an SL RRC reconfiguration complete message to the second terminal, and activates the newly sent SL RB configuration information, so as to ensure the wireless resource transmission between the first terminal and the second terminal.

[0134] Please refer to Figure 3 , Figure 3 is a flowchart of a SL DRX configuration method provided by the embodiments of the present application, and the method is applied to a second terminal. As Figure 3As shown, the method comprises the following steps:

[0135] In step 301, the second terminal sends SL DRX configuration information to the first terminal.

[0136] In the implementation scenario of the embodiments of the present application, the second terminal is taken as an example of the sender of the SL unicast service, that is, the sender of the SL DRX configuration, and the first terminal is taken as an example of the receiver of the SL unicast service, that is, the receiver of the SL DRX configuration, to specifically describe the technical solutions of the embodiments of the present application.

[0137] Optionally, after receiving the SL DRX configuration information sent by the second terminal, the first terminal judges whether the first terminal satisfies a first condition, and sends target information to the second terminal in the case where the first terminal satisfies the first condition. The specific content of the first condition can be referred to the above description. Figure 2 The description in the embodiments is not repeated in the present embodiment.

[0138] Optionally, after step 301, the method further comprises:

[0139] The second terminal receives the target information sent by the first terminal, and the target information comprises at least one of SL DRX configuration assistance information and SL DRX configuration rejection information; the SL DRX configuration assistance information is used to assist the second terminal to configure updated SL DRX configuration information; and the SL DRX configuration rejection information is used to reject the SL DRX configuration information.

[0140] Optionally, in the case where the target information comprises SL DRX configuration assistance information and SL DRX configuration rejection information, the SL DRX configuration assistance information and the SL DRX configuration rejection information satisfy any one of the following conditions:

[0141] The SL DRX configuration assistance information and the SL DRX configuration rejection information are carried in the SL RRC reconfiguration completion message;

[0142] The SL DRX configuration assistance information and the SL DRX configuration rejection information are carried in the SL RRC reconfiguration failure message;

[0144] The SL DRX configuration rejection information is carried in the SL RRC reconfiguration failure message, and the SL DRX configuration assistance information is carried in the SL UAI.

[0145] Optionally, in a case where the target information only includes the SL DRX configuration rejection information, the SL DRX configuration rejection information is carried in any one of the following:

[0146] an RRC reconfiguration complete message;

[0147] an RRC reconfiguration failure message.

[0148] It should be noted that the specific implementation of the first terminal sending the target information can be refer to the description in the above Figure 2 The embodiments in the description, and will not be repeated here.

[0149] Step 302, in a case where the second condition is met, the second terminal sends updated SL DRX configuration information to the first terminal.

[0150] The second condition includes at least one of the following:

[0151] The second terminal receives the target information sent by the first terminal, and the target information is used for negotiation of the SL DRX configuration information;

[0152] The time at which the second terminal sends the updated SL DRX configuration information is within a second timing time;

[0153] The number of times that the second terminal sends the updated SL DRX configuration information is within a second preset number of times;

[0154] The second terminal is allowed to initiate SL DRX reconfiguration.

[0155] In the embodiments of the present application, after the second terminal sends the SL DRX configuration information to the first terminal, the second terminal further judges whether the second condition is met, and in a case where the second condition is met, the second terminal sends updated SL DRX configuration information to the first terminal.

[0156] For example, after the second terminal sends the SL DRX configuration information to the first terminal, if the second terminal receives the target information sent by the first terminal, that is, the second terminal can know that the first terminal does not accept the SL DRX configuration information sent by the second terminal, then the second terminal sends updated SL DRX configuration information to the first terminal. So that the first terminal can realize SL discontinuous reception based on the updated SL DRX configuration information, and ensure the communication transmission between the first terminal and the second terminal. In this way, endless SL DRX rejection and SL DRX reconfiguration between the first terminal and the second terminal can be avoided, the SL DRX configuration process between terminals is simplified, the efficiency of the SL DRX process between terminals is improved, and the energy consumption of the terminal can also be saved.

[0157] For example, the second condition comprises that the second terminal sends the updated SL DRX configuration information within a second time period, and when the second terminal plans to send the updated SL DRX configuration information to the first terminal, if the second terminal sends the updated SL DRX configuration information within the second time period, the second terminal sends the updated SL DRX configuration information to the first terminal.

[0158] Alternatively, the second condition comprises that the second terminal sends the updated SL DRX configuration information within a second preset number of times, and when the second terminal plans to send the updated SL DRX configuration information to the first terminal, if the second terminal sends the updated SL DRX configuration information within the second preset number of times, the second terminal sends the updated SL DRX configuration information to the first terminal.

[0159] Alternatively, the second terminal sends the updated SL DRX configuration information to the first terminal in the case that the second terminal is allowed to initiate SL DRX reconfiguration.

[0160] Optionally, in the case that the second condition comprises that the second terminal sends the updated SL DRX configuration information within a second time period, the method further comprises:

[0161] The second terminal determines, by a second timer, whether the time for sending the updated SL DRX configuration information is within a second time period.

[0162] The starting time of the second timer is one of the following:

[0163] When the second terminal sends the SL DRX configuration information for the first time;

[0164] When the second terminal receives the target information for the first time.

[0165] It should be noted that the second terminal is configured with a second timer, which can be started when the second terminal sends the SL DRX configuration information to the first terminal for the first time, or can be started when the second terminal receives the target information sent by the first terminal for the first time. In the embodiment of the application, if the second terminal plans to send the updated SL DRX configuration information to the first terminal, and the time for the second terminal to send the updated SL DRX configuration information is within the second time period, the second terminal sends the SL DRX configuration information. If the time for the second terminal to send the updated SL DRX configuration information exceeds the second time period, the second terminal does not send or is not allowed to send the updated SL DRX configuration information.

[0166] Optionally, the number of the second timers is one or more; in the case of only one second timer being configured, the time length of the second timer corresponding to each terminal is configured; in the case of at least two second timers being configured, the time length of one second timer corresponding to each unicast link or a group of QoS attributes is configured.

[0167] For example, if one second timer is configured for one terminal, the time length of the second timer corresponding to each terminal is configured; if more than one second timer is configured for one terminal, the time length of one second timer corresponding to each unicast link or a group of QoS attributes of the terminal is configured. It should be noted that the final time of the time length of the configured second timer can be the final time of the second timer.

[0168] Optionally, the second timer is configured or pre-configured by a network side device.

[0169] In the second condition including that the number of times of sending the updated SL DRX configuration information by the second terminal is within the second preset number of times, the method further includes:

[0170] The second terminal determines whether the number of times of sending the updated SL DRX configuration information is within the second preset number of times through a second counter, the second counter is started when the second terminal sends the SL DRX configuration information for the first time, and the count value of the second counter is increased by one each time the second terminal sends the updated SL DRX configuration information.

[0171] Optionally, the second terminal is configured with a second counter and a maximum count value of the second counter, the initial count value of the second counter can be 0, and the second counter is started when the second terminal sends the SL DRX configuration information for the first time, and the count value of the second counter is increased by one each time the second terminal sends the SL DRX configuration information (including the updated SL DRX configuration information).

[0172] For example, the second preset number of times is 5, if the second terminal plans to send the updated SL DRX configuration information to the first terminal, and this time of sending the updated SL DRX configuration information is the third time of sending the SL DRX configuration information by the second terminal, then the number of times of sending the updated SL DRX configuration information by the second terminal is within the second preset number of times, and the second terminal can send the updated SL DRX configuration information this time. If the number of times of sending the updated SL DRX configuration information by the second terminal is greater than the second preset number of times, the second terminal does not send or is not allowed to send the updated SL DRX configuration information.

[0173] Optionally, the number of the second counters is one or more; in the case of only one second counter being configured, the maximum count value of the second counter is configured for each terminal; in the case of at least two second counters being configured, the maximum count value of each second counter is configured for each unicast link or a group of QoS attributes.

[0174] For example, if one second counter is configured for one terminal, the maximum count value of the second counter is configured for each terminal; if more than one second counter is configured for one terminal, the maximum count value of each second counter is configured for each unicast link or a group of QoS attributes of the terminal. It should be noted that the maximum count value of the configured second counter can be the first preset number of times.

[0175] Optionally, the second counter is configured or pre-configured by a network side device.

[0176] In the embodiments of the present application, in the case that the second condition includes that the second terminal is allowed to initiate SL DRX reconfiguration, the method further includes:

[0177] The second terminal determines whether it is allowed to initiate SL DRX reconfiguration through at least one of the following:

[0180] The resource scheduling mode of the second terminal;

[0181] Network side device configuration indication information;

[0182] Pre-configuration indication information;

[0183] Protocol agreement.

[0184] Optionally, in the case that the second terminal determines whether it is allowed to initiate SL DRX reconfiguration through the RRC connection state of the second terminal, the method further includes:

[0185] In the case that the second terminal is in an RRC Inactive state or an RRC Idle state, the second terminal determines that it is allowed to initiate SL DRX reconfiguration.

[0186] If the second terminal is in an RRC Connected state, the second terminal determines that it is not allowed to initiate SL DRX reconfiguration.

[0187] Optionally, in the case that the second terminal determines whether it is allowed to initiate SL DRX reconfiguration through a control node of the SL DRX configuration, the method further comprises:

[0188] In the case that the control node of the SL DRX configuration is determined by the second terminal, the second terminal determines that it is allowed to initiate SL DRX reconfiguration.

[0189] If the control node of the SL DRX configuration is a network side device (base station), the second terminal determines that it is not allowed to initiate SL DRX reconfiguration.

[0190] Optionally, in the case that the second terminal determines whether it is allowed to initiate SL DRX reconfiguration through a resource scheduling mode of the second terminal, the method further comprises:

[0191] In the case that the resource scheduling mode of the second terminal is a terminal autonomous mode (model 2), the second terminal determines that it is allowed to initiate SL DRX reconfiguration.

[0192] If the resource scheduling mode of the second terminal is a network side device (base station) scheduling mode (model 1), it is determined that the second terminal is not allowed to initiate SL DRX reconfiguration.

[0193] Optionally, whether the second terminal is allowed to initiate SL DRX reconfiguration can also be determined through other manners, such as network side device configuration indication information, pre-configuration indication information or protocol agreement, etc., and the embodiment does not make too much repetition.

[0194] In the embodiment of the application, after the second terminal sends the SL DRX configuration information to the first terminal, the second terminal only sends the updated SL DRX configuration information to the first terminal in the case that the second condition is met, so that the second terminal can avoid re-sending the SL DRX configuration information to the first terminal. In this way, through the agreed second condition, the sending behavior of the SL DRX configuration information between terminals can be standardized, endless SL DRX rejection and SL DRX reconfiguration between terminals can be avoided, the SL DRX configuration process between terminals can be simplified, the SL DRX process efficiency of the terminal can be improved, and the energy consumption of the terminal can also be saved.

[0195] Optionally, the method further comprises at least one of the following:

[0196] The second terminal no longer sends the updated SL DRX configuration information to the first terminal in the case that the second condition is not met;

[0197] The transmission state between the first terminal and the second terminal is an SL DRX sleep state or a non-SL DRX state.

[0198] Optionally, after receiving the target information sent by the first terminal, if the second terminal does not meet the second condition, for example, the second terminal is not allowed to initiate SL DRX reconfiguration, or the number of times that the second terminal plans to send the updated SL DRX configuration information exceeds the second preset number of times, or the time at which the second terminal plans to send the updated SL DRX configuration information exceeds the second timing time, the second terminal does not send the updated SL DRX configuration information to the first terminal.

[0199] Alternatively, after receiving the target information sent by the first terminal, that is, learning that the first terminal does not receive the SL DRX configuration information sent by the second terminal, the transmission state between the first terminal and the second terminal is in the SL DRX sleep state or the non-SL DRX state, for example, the second terminal no longer sends the SL DRX configuration information to the first terminal, or the first terminal and the second terminal stop the transmission mode of discontinuous reception.

[0200] Optionally, the second terminal sends the SL DRX configuration information to the first terminal, comprising:

[0201] The second terminal sends the SL DRX configuration information and the SL RB configuration information to the first terminal.

[0202] It should be noted that the SL DRX configuration of the second terminal to the first terminal can occur in the SL RRC reconfiguration completion process or in the SL RRC reconfiguration failure process, and the related behaviors of the first terminal and the second terminal in the two processes can be referred to the above Figure 1 The specific description in the embodiments will not be repeated here. Among them, in the SL RRC reconfiguration completion process or the SL RRC reconfiguration failure process, the second terminal can send the SL DRX configuration information and the SL RB configuration information to the first terminal at the same time.

[0203] Optionally, the target information is carried in the SL RRC reconfiguration failure message, and after the second terminal receives the target information sent by the first terminal, the method further comprises:

[0204] The second terminal re-sends the SL RB configuration information to the first terminal.

[0205] In this embodiment, the SL DRX configuration of the second terminal to the first terminal occurs in the SL RRC reconfiguration failure procedure. After receiving the target information sent by the first terminal, if the second terminal does not satisfy the second condition, the second terminal will not send the updated SL RRC configuration information to the first terminal, and the second terminal can be the first terminal to resend the SL RB configuration information. For example, the second terminal can send a new SL RRC reconfiguration message carrying the SL RB configuration information, and the first terminal can perform the SL RRC reconfiguration procedure based on the SL RRC reconfiguration message. If the SL RRC reconfiguration procedure is successful, the first terminal sends an SL RRC reconfiguration complete message to the second terminal, and the newly sent SL RB configuration information takes effect, so as to ensure the wireless resource transmission between the first terminal and the second terminal.

[0206] Please refer to Figure 4a , Figure 4a Figure 3 is a flowchart of a method for SL DRX configuration provided by an embodiment of the present application. In this embodiment, the SL DRX configuration of the second terminal (UE2) to the first terminal (UE1) occurs in the SL RRC reconfiguration complete procedure. As shown in Figure 3, the method comprises the following steps: Figure 4a

[0207] Step S11. The second terminal sends an SL RRC reconfiguration message to the first terminal, and the SL RRC reconfiguration message carries SL DRX configuration information, or carries SL DRX configuration and SL RB configuration information.

[0208] Step S12. The first terminal judges whether the SL DRX configuration negotiation condition (i.e. the first condition described above) is satisfied.

[0209] Step S13. If the first terminal satisfies the SL DRX configuration negotiation condition, the first terminal sends an SL RRC reconfiguration complete message to the second terminal, and the SL RRC reconfiguration complete message carries SL DRX configuration rejection information and / or SL DRX configuration auxiliary information; or the first terminal sends an SL RRC reconfiguration complete message and an SL UAI to the second terminal, wherein the SL RRC reconfiguration complete message carries the SL DRX configuration rejection information, and the SL UAI carries the SL DRX configuration auxiliary information.

[0210] Step S14. The second terminal judges whether the SL DRX configuration reconfiguration condition (i.e. the second condition described above) is satisfied.

[0211] ​Step S15. If the second terminal satisfies the condition of SL DRX configuration reconfiguration, the updated SL DRX configuration information is sent to the first terminal, and if the second terminal does not satisfy the condition of SL DRX configuration reconfiguration, it is defaulted that the transmission between the first terminal and the second terminal is in SL DRX off state; wherein, if the SL RB configuration information is sent in step S11, the SL RB configuration information is simultaneously in effect.

[0212] It should be noted that the implementation process of the method provided in the embodiment can be combined with the specific description of the above-mentioned Figure 2 and Figure 3 the same technical effects can be achieved, and thus will not be described here again to avoid repetition.

As shown in Figure 4b , the method comprises the following steps:

[0214] Step S21. The second terminal sends an SL RRC reconfiguration message to the first terminal, wherein the SL RRC reconfiguration message carries SL DRX configuration information, or carries SL DRX configuration and SL RB configuration information.

[0215] Step S22. The first terminal judges whether the SL DRX configuration negotiation condition (i.e. the first condition described above) is satisfied.

[0216] Step S23. If the first terminal satisfies the SL DRX configuration negotiation condition, the first terminal sends an SL RRC reconfiguration failure message to the second terminal, wherein the SL RRC reconfiguration failure message carries SL DRX configuration rejection information and / or SL DRX configuration auxiliary information; or the first terminal sends an SL RRC reconfiguration failure message and an SL UAI to the second terminal, wherein the SL RRC reconfiguration failure message carries SL DRX configuration rejection information, and the SL UAI carries SL DRX configuration auxiliary information.

[0217] Step S24. The second terminal judges whether the condition of SL DRX configuration reconfiguration (i.e. the second condition described above) is satisfied.

[0218] Step S25. If the second terminal meets the condition of SL DRX configuration reconfiguration, the updated SL DRX configuration information is sent to the first terminal, and if the second terminal does not meet the condition of SL DRX configuration reconfiguration, it is defaulted that the transmission between the first terminal and the second terminal is in SL DRX off state; wherein, if the SL RB configuration information is sent in step S11, a new SL RRC reconfiguration message is sent at the same time, and the SL RB configuration information is carried in the SL RRC reconfiguration message.
