[0050] The above and / or additional aspects and advantages of the present invention will become apparent and more readily understood from the following detailed description of the embodiments taken in conjunction with the drawings. [Figure 1] 1 is a schematic flowchart of a sidelink communication control method according to an embodiment of the present invention. [Diagram 2] 1 is a schematic flowchart of a sidelink communication control method according to another embodiment of the present invention; [Diagram 3] FIG. 2 is a structural schematic diagram of a sidelink communication control device according to an embodiment of the present invention; [Figure 4] FIG. 2 is a structural schematic diagram of a sidelink communication control device of another embodiment of the present invention; [Diagram 5] FIG. 2 is a structural block diagram of a communication device according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0051] Hereinafter, the embodiments of the present invention will be described in detail, and examples of the embodiments are shown in the drawings, and the same or similar reference numerals throughout represent the same or similar parts or parts having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are intended to explain the present invention, and should not be understood as limiting the present invention.

[0052] In the related art, to achieve energy saving in discontinuous reception (DRX) based on R17 NR sidelink, the associated user equipment performs energy saving mode by turning off the receiver and entering a sleep state, in which the user equipment does not need to perform sidelink transmission / reception and channel measurement operations in order to save energy.

[0053] In the case of energy saving in which the user equipment performs discontinuous reception, the user equipment can periodically execute the DRX on timer, during which the user equipment is in an active state and needs to perform operations such as detecting and receiving a downlink control channel, and when the DRX on timer expires, the user equipment can transition to an inactive state and does not need to perform downlink reception operations. The start time, period, operating time, etc. of the DRX on timer can be preset or obtained based on the setting of the base station, and are not included in the content of this patent, so detailed description is omitted here.

[0054] However, the DRX operation of the receiving UE affects the resource selection of the transmitting UE, and if the transmission resource selected by the transmitting UE is in the DRX off time period of the receiving UE, the receiving UE cannot receive the sidelink transmission. If the transmitting UE cannot control and coordinate the receiving UE's DRX, the transmitting UE can ensure that the time-frequency resource selected by its sidelink transmission is within the active time period of the receiving UE.

[0055] However, the additional resource selection restriction increases the probability that the selected resources are strongly interfered with, degrading system performance, and the transmitting user equipment cannot ensure that the reserved time-frequency resources are also within the receiving active period.

[0056] Therefore, the present invention provides a technical solution that enables a transmitting user equipment to control and adjust the DRX of a receiving user equipment.

[0057] Hereinafter, a sidelink communication control method, an apparatus, a device, and a storage medium thereof according to embodiments of the present invention will be described in conjunction with the drawings. Here, for ease of explanation, the explanation will be given focusing on the transmitting device side and the receiving device side, respectively. Here, the transmitting device and the receiving device are user equipment on the transmitting side and user equipment on the receiving side of sidelink data communication, respectively, and the transmitting device and the receiving device may be mobile terminals, etc.

[0058] The following description will first focus on the transmitting device side.

[0059] 1 is a flowchart of a sidelink communication control method provided by an embodiment of the present invention, which includes the following step 101:

[0060] Step 101: sending sidelink control signaling including first indication information for controlling discontinuous reception (DRX) of a receiving device.

[0061] In this embodiment, the transmitting device sends first instruction information to control the relevant operation of discontinuous reception (DRX) of the receiving device, thereby facilitating the transmitting device to directly instruct the discontinuous reception (DRX) operation of the receiving device, avoiding the transmitting device from being unable to ensure that the reserved resources are necessarily within the active period of the receiving device, and balancing energy saving and system performance.

[0062] It should be noted that the reserved resources of the transmitting device may be, for example, resource locations indicating time-frequency reserved by the transmitting device for future sidelink transmission communications. It is an object of the present invention to enable the receiving device to enter the active state before the reserved time-frequency resources.

[0063] It should be noted that, in different application scenarios, the transmission of the sidelink control signaling can be realized in different manners, one possible implementation is that the sidelink control signaling is physical layer sidelink control information (SCI), i.e., the transmission of the sidelink control signaling is realized by physical layer sidelink control information, and another possible implementation is that the sidelink control signaling is medium access control element (MAC CE), i.e., the transmission of the sidelink control signaling is realized by MAC layer control element.

[0064] Thus, in the sidelink communication control method according to the embodiment of the present invention, the transmitting device directly transmits sidelink control signaling to the user equipment, where the sidelink control signaling includes first indication information for controlling discontinuous reception (DRX) of the receiving device, thereby avoiding the transmitting device from being unable to ensure that the reserved resources are always within the active period of the receiving device, and thus balancing energy saving and system performance.

[0065] In actual implementation, in order to facilitate balancing energy saving and system performance, the transmitting device may send first instruction information to the user equipment, carrying an operation related to controlling the receiving device to perform discontinuous reception (DRX), and may include any instruction content that can successfully dock the resources of the transmitting device and the receiving device.

[0066] The following mainly describes three possible instruction contents of the first instruction information as examples.

[0067] Type 1 In this embodiment, the first instruction information includes information indicating the time when the receiving device will enter the active state, so that the transmitting device reserves resources for the receiving device to enter the active state.

[0068] In some possible examples, the sidelink control signaling is physical layer sidelink control information, the physical layer sidelink control information including a second indication of reserved time-frequency resource locations for future sidelink transmissions, where the second indication of the reserved time-frequency resource locations is further used to indicate a time at which the receiving device enters the active state, such that the receiving device enters the active reception state before the reserved time-frequency resources to avoid energy consumption and improve system performance.

[0069] Here, the second indication information indicating the time when the receiving device enters the active state may include different content.

[0070] Example 1 In this embodiment, the indication information of the reserved time-frequency resource position also indicates the time at which the receiving equipment enters the active state, and entering the active state T times before the reserved time-frequency resource position ensures that the receiving equipment needs to enter the active receiving state T times before the time-frequency resource reserved by the transmitting equipment.

[0071] Here, "T time before" refers to T time before a reference time position where the reserved time-frequency resource is located, for example, the reference time position is the start OFDM symbol position of the time-frequency resource or the slot where the reserved time-frequency resource is located, etc., and the unit of T may be a physical time unit or a logical time unit such as a second, a millisecond, a frame, a subframe, a slot, an OFDM symbol, or a slot where the appropriate sidelink time-frequency resource is located.

[0072] In some possible embodiments, the possible range of T includes 0, may be a fixed value, the possible value may be determined by the capability of the device, or information for determining T may be read by receiving downlink signaling sent from a network side such as a base station, or by pre-configured information, and the information of T includes the possible values ​​or possible ranges of T mentioned above.

[0073] Here, a set of values ​​can be (pre)set for T, and the physical layer control information indicates which value to take specifically, i.e., the physical layer control information includes information indicating T, and the information of T includes the above-mentioned possible values ​​or range of possible values ​​of T. As mentioned above, in some possible embodiments, the physical layer control information includes whether the second indication information is used to indicate the time when the receiving device enters an active state. Note that, in the physical layer control information, the second indication information includes whether the receiving device is used to indicate whether to enter an active state. For example, in the physical layer control information, when the information of an information bit representing whether the second indication information is used to indicate whether to enter an active state is 1, it indicates that the second indication information is used to indicate whether to enter an active state, and when the information of the information bit is 0, it indicates that the second indication information is not used to indicate whether to enter an active state.

[0074] For example, when indication information indicating a possible value of T is carried in the 1st stage SCI or the corresponding 2nd stage SCI, the receiving device uses the possible value indicating T in the 1st stage SCI or the corresponding 2nd stage SCI when entering an active state based on the time-frequency resource information reserved in the 1st stage SCI.

[0075] Example 2 In this embodiment, the first indication information of the reserved time-frequency resource position includes information indicating an offset value of the time at which the receiving equipment enters an active state, thereby ensuring that the receiving equipment needs to enter the active receiving state before the time-frequency resource reserved by the transmitting equipment.

[0076] In some possible embodiments, the receiving device can obtain information on the offset value at the time when the receiving device enters the active state by receiving downlink signaling transmitted from the network side, such as a base station, or by reading pre-configured information, and the offset value information includes possible values ​​or a range of possible values ​​for the offset value, for example, the configured offset values ​​are {-8, -4, -2, 0, 2, 4, 8}, and 3 bits indicate which specific offset value is to be used.

[0077] In this embodiment, the sidelink control signaling may indicate whether to convey an offset value for the time of entering the active state, and the receiving device adjusts the time of entering the active state in the next period based on the received offset value. For example, if the indicated offset value is -4 slots, the receiving device will enter the active state 4 slots earlier in the next period, and if the indicated offset value is 2 slots, the receiving device will enter the active state 2 slots later. The unit of the indicated offset value here and hereafter may be a physical time unit or a logical time unit such as seconds, milliseconds, frames, subframes, slots, OFDM symbols, slots where appropriate sidelink time-frequency resources exist, etc.

[0078] For example, the receiving device determines the time to start the DRX on timer based on the current frame number and slot number, and starts the DRX on timer only when (DFN * number of slots in one frame + current slot number) % (DRX cycle) = (set offset) % (DRX cycle), where DFN is the sidelink frame number, and the DRX cycle and set offset are values ​​set or preset by the base station.

[0079] That is, in this embodiment, after receiving an SCI or MAC CE carrying an offset instruction, the receiving device judges the next start time of the DRX on timer according to the following formula, which is as follows: (DFN*number of slots in one frame+current slot number)%(DRX cycle)=(set offset+offset instruction)%(DRX cycle). Here, the offset instruction is the offset value of the instruction to be carried.

[0080] An indication of whether the current sidelink control signaling transmission carries an offset indication may be included in the physical layer sidelink control information SCI, and a different sidelink control signaling format can implicitly indicate whether the current sidelink control signaling transmission carries an offset indication or not. For example, only when a different 2nd stage SCI format is defined and a specific 2nd stage SCI is selected, the physical layer sidelink control information includes an information field for the offset indication.

[0081] The offset indication carried in the physical layer sidelink control information or the MAC layer control element may be applied to the next DRX cycle only, to the following DRX cycles within a certain period of time, or to all following DRX cycles, where the length of the certain period of time may be determined by a base station configuration or a preconfiguration method.

[0082] If the receiving device receives multiple sidelink control signalings carrying offset instructions within one DRX period, the receiving device uses the last received offset instruction.

[0083] Type 2 In this example, the first instruction information for controlling discontinuous reception (DRX) of the receiving device includes information on the length of time for which the receiving device is to enter the active state.

[0084] In some possible examples, the instruction indicating the length of time the receiving device enters the active state includes indicating an offset value for a change in the length of time the receiving device enters the active state or indicating possible values ​​for the length of time the receiving device enters the active state.

[0085] In this embodiment, an indication of whether the current transmission carries an offset indication can be included in the sidelink control signaling, or a different sidelink control signaling format can also implicitly indicate whether the current transmission carries an offset indication, where the offset indication is used to indicate whether the receiving device carries an indication of the length of time to enter the active state.

[0086] It should be noted that for different scenes, the time length indications may contain different content.

[0087] Example 1 In this example, indicating an offset value for a change in the length of time that the receiving device enters the active state includes obtaining a possible value or a possible range of values ​​for the offset value for a change in the length of time that the receiving device enters the active state by receiving downlink signaling transmitted from the base station side or by reading a pre-setting.

[0088] In this embodiment, the receiving device can extend or shorten the active period of the DRX cycle based on the received offset value, for example, by extending or shortening the expire time of the DrX on timer.

[0089] In this example, information on the length of time that the receiving device will enter an active state is obtained by receiving downlink signaling transmitted from an Internet device such as a base station or by reading pre-configured information, and the information includes possible values ​​or a range of possible values ​​for the length of time.

[0090] Example 2 In this example, indicating possible values ​​for the length of time that the receiving device is to enter the active state is This includes determining information about an offset value for a change in the length of time that the receiving device enters an active state by receiving downlink signaling transmitted from an Internet device such as a base station or reading pre-configured information, the information including possible values ​​or a range of possible values ​​for the offset value.

[0091] Type 3 In this embodiment, the first instruction information includes information of the DRX cycle of the receiving device. The information may be applied only to the current DRX cycle, or to the next DRX cycle, or to the subsequent DRX cycles within a certain period of time, or to all subsequent DRX cycles. When applied to the subsequent DRX cycles within a certain period of time, the length of the certain period of time can be determined by a method set by the base station or a method set in advance.

[0092] Moreover, in different application scenarios, the first indication information may include different contents, which are illustratively described as follows.

[0093] Example 1 In this example, the instruction information includes an offset value that indicates a change in the DRX period of the receiving device. For example, the set offset value is {-8, -4, -2, 0, 2, 4, 8}, and the specific offset value to be used is represented by 3 bits. The unit of the indicated offset value may be a physical time unit, or a logical time unit such as a second, a millisecond, a frame, a subframe, a slot, an OFDM symbol, or a slot in which a suitable sidelink time-frequency resource exists.

[0094] Example 2 In this example, the indication information includes possible values ​​indicating the DRX period of the receiving device, such as the length of the active and end periods.

[0095] Here, in some possible embodiments, information on the offset value of the change in the DRX period of the receiving device can be obtained by receiving downlink signaling transmitted from an Internet device such as a base station or by reading pre-configured information, and the offset value information includes possible values ​​or a range of possible values ​​of the offset value.

[0096] In some other possible embodiments, information of the DRX period of the receiving device can be obtained by receiving downlink signaling transmitted from an Internet device side such as a base station or by reading pre-configured information, and the information includes possible values ​​or possible value ranges of the DRX period.

[0097] In the actual implementation process, the sidelink control signaling may directly indicate whether to carry the indication information of the DRX period of the receiving device, or may use different sidelink control signaling formats to implicitly indicate whether the current sidelink control signaling transmission carries the DRX period value indication, and may use the 1st stage SCI, the 2nd stage SCI, or the sum of both, or other SCI formats to implicitly indicate whether the current sidelink control signaling transmission carries the DRX period value indication, for example, carrying a 1-bit information field in the 1st stage SCI or the corresponding 2nd stage SCI. Only if the possible value is "yes", the receiving device enters the active state based on the resource reservation information contained in the 1st stage SCI or the 1st stage SCI corresponding to the current 2nd stage SCI transmission. The 1st stage SCI corresponding to the 2nd stage SCI here refers to that they correspond to the same PSSCH transmission.

[0098] Here, in some possible embodiments, the indication of the DRX period may only be applicable for a certain period of time thereafter, where this length of time may be determined in a manner that is set by the base station or pre-set.

[0099] As described above, the sidelink communication instruction method according to the embodiment of the present disclosure can flexibly use different methods according to the scene to generate instruction information for a discontinuous reception (DRX) operation of a receiving device, thereby improving the flexibility of sidelink communication instructions.

[0100] Hereinafter, a sidelink communication control method according to an embodiment of the present invention will be described with reference to the receiving device side.

[0101] FIG. 2 is a flowchart of another method provided by an embodiment of the present invention, where the method includes the following steps 201-202.

[0102] Step 201, receiving sidelink control signaling including first indication information for controlling discontinuous reception (DRX) of a receiving device.

[0103] In this embodiment, the receiving device receives a sidelink control signaling sent by a transmitting device, where the sidelink control signaling carries first instruction information for controlling discontinuous reception (DRX) of the receiving device, and the instruction information includes various possible formats, which will be described in the following embodiments, and detailed description is omitted here.

[0104] Step 202: Perform DRX operation according to the first indication information.

[0105] In this embodiment, the receiving device directly performs the DRX operation according to the first indication information, so that the receiving device already enters the active state when the transmitting device is in the reserved resource, and balances the system performance and energy consumption.

[0106] Here, in this embodiment, the resource reservation information reserved by the transmitting device may be a non-periodic resource reservation field indicating the time-frequency resources of the subsequent repeated transmission of the same transmission block (TB), or may be a periodic resource reservation field indicating the possible periodic value of the periodic reservation. The receiving device may enter an active state based only on the time domain position of the reserved resource indicated by the periodic reservation, or may enter an active state based only on the time domain position of the reserved resource indicated by the non-periodic reservation, or may include both.

[0107] As described above, in the sidelink communication control method according to the embodiment of the present invention, a receiving device receives a receiving sidelink control signaling sent by a transmitting device, the sidelink control signaling carrying first indication information for the receiving device to perform a discontinuous reception (DRX) operation, and the receiving device performs the DRX operation according to the first indication information, thereby avoiding the transmitting device being unable to ensure that the reserved resources are always within the active period of the receiving device, and balancing energy saving and system performance.

[0108] In the actual implementation process, the manner in which the user equipment performs DRX operation based on the instruction information varies according to different scenes, and logically can include any manner that can realize the reservation resource adjustment by the transmitting equipment. The following describes three possible implementation forms as examples.

[0109] Type 1 In this example, performing the DRX operation based on the first instruction information includes entering an active state based on information on the time at which the receiving device instructed by the first instruction information enters the active state.

[0110] In some possible embodiments, if the sidelink control signaling is physical layer sidelink control information and the physical sidelink control information comprises a second indication of reserved time-frequency resource locations, the time to enter the active state can be determined based on the indication of reserved time-frequency resource locations for future sidelink transmissions indicated by the second indication, thereby allowing the receiving device to enter the active state under the reserved time-frequency resources and avoid increasing energy consumption.

[0111] Here, the indication information of the time when the control receiving device enters the active state may be different in different scenes.

[0112] Example 1 In this example, the active state is entered T times before the time-frequency resource indicated by the reserved time-frequency resource location indication.

[0113] Here, the time T can be obtained by receiving downlink control signaling transmitted from an Internet device such as a base station, or can be obtained by preconfiguration information, or can be obtained by receiving indication information of possible values ​​of T carried in physical layer sidelink control information.

[0114] Here, "T time before" refers to T time before a certain reference time position of the reserved time-frequency resource, for example, the reference time position is the start OFDM symbol position of the time-frequency resource, or the slot where the reserved time-frequency resource is located, etc., and the unit of T may be a physical time unit or a logical time unit such as seconds, milliseconds, frames, subframes, slots, OFDM symbols, slots where the appropriate sidelink time-frequency resource exists, etc.

[0115] In some possible embodiments, the range of possible values ​​for T includes 0, may be a fixed value, the possible values ​​may be determined by device capabilities, or the possible values ​​may be obtained by receiving base station downlink control signaling or reading preconfiguration information.

[0116] Here, a set of values ​​can be (pre)configured for T, and as mentioned above, the physical layer control information indicates which value to take specifically. As mentioned above, in some possible embodiments, the indication of the reserved time-frequency resource locations in the physical layer control information also indicates an indication of the time at which the receiving device should enter the active state or not.

[0117] For example, indication information indicating a possible value of T is carried in the 1st stage SCI or the corresponding 2nd stage SCI, and when the receiving device enters the active state based on the time-frequency resource information reserved in the 1st stage SCI, the receiving device uses the possible value of T indicated in the 1st stage SCI or the corresponding 2nd stage SCI.

[0118] Example 2 In this example, entering the active state according to the information of the time when the receiving device enters the active state indicated by the first indication information includes adjusting the time when the receiving device enters the active state in the subsequent DRX period according to an offset value of the time when the receiving device enters the active state indicated by the first indication information. For example, the set offset value is {-8, -4, -2, 0, 2, 4, 8}, and the specific offset value to be used can be indicated by 3 bits.

[0119] In some possible examples, the step of adjusting the time at which the receiving device enters the active state in a subsequent DRX period based on first indication information of an offset value of the time at which the receiving device enters the active state includes at least one of the following (1) to (3):

[0120] (1) The time at which the receiving device enters the active state in the next DRX cycle is adjusted based on the first instruction information indicating an offset value of the time at which the receiving device enters the active state. For example, the time at which the receiving device enters the active state in the next DRX cycle can be advanced or delayed based on the offset value.

[0121] For example, if the indicated offset value is -4 slots, the receiving device will enter the active state 4 slots earlier in the next period, and if the indicated offset value is 2 slots, the receiving device will enter the active state 2 slots later. The unit of the indicated offset value here and hereafter may be a physical time unit or a logical time unit such as seconds, milliseconds, frames, subframes, slots, OFDM symbols, slots in which appropriate sidelink time-frequency resources exist, etc.

[0122] For example, the receiving device will start the DRX on timer in the next DRX cycle based on the current frame number and slot number only when (DFN * number of slots in one frame + current slot number) % (DRX cycle) = (setting offset) % (DRX cycle), where DFN is the sidelink frame number, and the DRX cycle and setting offset are set by the base station or are preset values.

[0123] (2) The time at which the receiving device enters the active state is adjusted in the DRX period within the subsequent predetermined time period based on the first instruction information indicating the offset value of the time at which the receiving device enters the active state. That is, in this embodiment, all DRX periods included in the subsequent predetermined time period are determined, and the time at which the receiving device enters the active state can be advanced or delayed in all the DRX periods based on the offset value. In some possible embodiments, the length of the predetermined time period corresponding to the adjustment of the time at which the receiving device enters the active state in the DRX period within the subsequent predetermined time period can be obtained by receiving downlink signaling transmitted from the Internet device side such as a base station or reading pre-configuration information.

[0124] For example, if the indicated offset value is −4 slots, the receiving device will enter the active state 4 slots earlier than scheduled in all DRX periods within the predetermined time period, and if the indicated offset value is 2 slots, the receiving device will enter the active state 2 slots later than scheduled in all DRX periods within the predetermined time period. The unit of the indicated offset value here and hereinafter may be a physical time unit or a logical time unit such as seconds, milliseconds, frames, subframes, slots, OFDM symbols, slots in which appropriate sidelink time-frequency resources exist, etc.

[0125] For example, the receiving device determines the time of the DRX on timer to activate all DRX cycles within a specified time period based on the current frame number and slot number, and activates the DRX on timer only when (DFN * number of slots in one frame + current slot number) % (DRX cycle) = (set offset) % (DRX cycle), where DFN is the sidelink frame number, and the DRX cycle and set offset are set by the base station or are preset values.

[0126] (3) The time at which the receiving device enters the active state is adjusted for all subsequent DRX cycles based on the first instruction information indicating an offset value for the time at which the receiving device enters the active state. In this embodiment, the time at which the receiving device enters the active state is advanced or delayed for all DRX cycles directly based on the offset value.

[0127] For example, if the indicated offset value is -4 slots, the receiving device will enter the active state 4 slots earlier in every subsequent DRX period, and if the indicated offset value is 2 slots, the receiving device will enter the active state 2 slots later than scheduled in every subsequent DRX period. The unit of the indicated offset value here and below may be a physical time unit or a logical time unit such as seconds, milliseconds, frames, subframes, slots, OFDM symbols, slots in which appropriate sidelink time-frequency resources exist, etc.

[0128] For example, the receiving device determines the time of the DRX on timer to activate all subsequent DRX cycles based on the current frame number and slot number, and activates the DRX on timer only when (DFN * number of slots in one frame + current slot number) % (DRX cycle) = (configured offset) % (DRX cycle), where DFN is the sidelink frame number, and the DRX cycle and the configured offset are configured by the base station or are preset values.

[0129] In an actual execution process, if multiple pieces of instruction information indicating an offset value of the time at which the receiving device enters the active state are received within one DRX cycle, the last received offset instruction information is used to adjust the time at which the receiving device enters the active state in the subsequent DRX cycle.

[0130] Type 2 In this embodiment, performing a DRX operation based on the first instruction information involves controlling the active period within the DRX cycle based on information on the length of time that the receiving device will enter an active state as instructed by the first instruction information.

[0131] In some possible embodiments, the active period within the DRX cycle is lengthened or shortened based on an offset value of the change in the length of time that the receiving device is in the active state.

[0132] In some other embodiments, the receiving device determines the active period within the DRX period based on the possible lengths of time that it will be in the active state.

[0133] The method for determining the active period within the DRX cycle based on the possible values ​​of the length of time that the receiving device enters the active state includes any of the following (1) to (4).

[0134] (1) Determine the active period within the DRX cycle based on the possible values ​​for the length of time the receiving device is in the active state.

[0135] In this embodiment, the length of time that the designated receiving device is in an active state is defined as the active period within the DRX cycle.

[0136] (2) Controlling the active period within the next DRX cycle based on the first instruction information indicating the length of time for which the instructed receiving device is to enter the active state.

[0137] In this embodiment, the length of time that the instructed receiving device goes into the active state is set as the active period in the next DRX cycle.

[0138] (3) Controlling an active period within a DRX cycle within a subsequent predetermined time period based on first instruction information that indicates the length of time for which the indicated receiving device is to enter an active state.

[0139] In this embodiment, all DRX cycles included in the subsequent predetermined time period are determined, and the length of time during which the receiving device directly enters the active state is set as the active period of all DRX cycles included in the subsequent predetermined time period.

[0140] In one embodiment of the present disclosure, by receiving downlink signaling transmitted from an Internet device such as a base station or by reading pre-configured information, the receiving device can obtain the length of the predetermined time period corresponding to controlling the active period within a DRX period within a subsequent predetermined time period.

[0141] (4) Controlling the active period in all subsequent DRX cycles based on the first indication information indicating the length of time for which the receiving device is to enter the active state.

[0142] In this embodiment, all subsequent DRX cycles can be determined, and the length of time that the indicated receiving device enters the active state can be directly set as the active period of all subsequent DRX cycles.

[0143] Type 3 In this embodiment, performing the DRX operation based on the first instruction information involves determining the DRX period based on the instruction information of the DRX period of the receiving device instructed by the first instruction information.

[0144] In addition, in different application scenarios, the instruction information may include the following contents, examples of which are as follows:

[0145] Example 1 In this example, the instruction information includes an offset value that instructs the receiving device to change the DRX period, and extends or shortens the DRX period based on the offset value that instructs the receiving device to change the DRX period.

[0146] For example, when the set offset value is {-8, -4, -2, 0, 2, 4, 8}, a specific offset value to be used is indicated by 3 bits. The unit of the indicated offset value may be a physical time unit, or may be a logical time unit such as a second, a millisecond, a frame, a subframe, a slot, an OFDM symbol, or a slot in which a suitable sidelink time-frequency resource exists.

[0147] Example 2 In this example, the instruction information includes an instruction for a possible value of the DRX cycle of the receiving device, and thus determines the DRX cycle based on the possible value of the indicated DRX cycle of the receiving device, for example, indicating an active period and an end period of the DRX cycle of the receiving device.

[0148] In this embodiment, determining the DRX cycle based on the indication information of the DRX cycle of the receiving device carried in the sidelink control signaling includes any of the following (1) to (4).

[0149] (1) The current DRX cycle is determined based on first instruction information that indicates the DRX cycle of the receiving device.

[0150] In this embodiment, the current DRX cycle is determined based on instruction information that directly instructs the DRX cycle of the receiving device, and the current DRX cycle is adjusted based only on the instruction information.

[0151] (2) The next DRX cycle is determined based on the first instruction information that indicates the DRX cycle of the receiving device.

[0152] In this embodiment, the next DRX cycle is determined based on instruction information that directly instructs the DRX cycle of the receiving device, and the next DRX cycle is adjusted based only on the instruction information.

[0153] (3) Based on first instruction information instructing the DRX cycle of the receiving device, a DRX cycle within a subsequent predetermined time period is determined.

[0154] In this embodiment, the receiving device can obtain the length of the predetermined time period corresponding to the determination of the DRX period within the subsequent predetermined time period by receiving downlink signaling transmitted from an Internet device such as a base station or by reading pre-configured information.

[0155] In this embodiment, all DRX cycles within the subsequent specified time period are determined, and based on instruction information that indicates the DRX cycle of the receiving device, all DRX cycles within the subsequent specified time period are determined, and all DRX cycles within the subsequent specified time period are adjusted based on the instruction information.

[0156] (4) All subsequent DRX cycles are determined based on the first instruction information instructing the DRX cycle of the receiving device.

[0157] In this embodiment, all subsequent DRX cycles are determined based on instruction information that indicates the DRX cycle of the receiving device, and all subsequent DRX cycles within a specified time period are adjusted based on the instruction information.
