[0093] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.
[0094] In the embodiments of the present application, the term "plural" refers to two or more, and other quantifiers are similar.
[0095] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0096] Before describing the embodiments of the present application, for the convenience of understanding, first, the commonly used technical terms in the present application are introduced:
[0097] HARQ refers to Hybrid Automatic Repeat Request.
[0098] DRX refers to Discontinuous Reception.
[0099] PDCCH, Physical Downlink Control Channel.
[0100] PUCCH, Physical Uplink Control Channel.
[0101] NACK, Negative ACK.
[0102] ACK, ACKnowledgment.
[0103] RRC, Radio Resource Control.
[0104] In traditional cellular network communication, as Figure 1 shown, uplink data, downlink data, and control information are transmitted between the terminal (UE) and the network-side device through the Uu interface.
[0105] In a mobile communication system based on a shared channel, such as LTE (Long Term Evolution), the transmission of uplink data and downlink data is controlled by the base station (eNB) scheduler. When the scheduler determines to schedule a certain terminal, it can notify the terminal through the control channel on which resources to send or receive data. The terminal (UE) listens to the control channel. When it detects the scheduling information containing itself, it completes the transmission (uplink) or reception (downlink) of data according to the indication on the control channel. When the terminal is in the active state, since the terminal is not sure when the base station scheduler schedules it, a common working mode is that the terminal needs to continuously listen to the control channel and parse each subframe containing its downlink scheduling control channel to determine whether it is scheduled. This working method can obtain a high scheduling efficiency when the terminal has a large amount of data and may be frequently scheduled. However, for some services, the arrival frequency of data is low, resulting in fewer times the terminal is scheduled. If the terminal still continuously listens to the control channel, it will undoubtedly increase the power consumption of the terminal.
[0106] Therefore, to solve the problem of high terminal power consumption, the cellular network communication system adopts the DRX working mode. In this working mode, the terminal can periodically listen to the control channel, thereby achieving the purpose of saving power.
[0107] Among them, the basic principle of DRX is as Figure 2 shown. On duration represents the time period when the terminal listens to the control channel. During this time period, the radio frequency channel of the terminal is turned on and continuously listens to the control channel. At other times except On duration, that is Figure 2During the time period corresponding to the opportunity for DRX, the terminal is in the Sleep state, and its radio frequency link will be turned off and no longer monitor the control channel to achieve the purpose of saving power. Among them, the On Duration appears periodically, and the specific cycle is configured by the base station.
[0108] The DRX mechanism of the cellular network considers the arrival model of data services, that is, the arrival of data packets is bursty. It can be understood that once a data packet arrives, a relatively large number of packets will arrive continuously within a short period of time. To adapt to this service arrival characteristic, the LTE DRX process uses multiple timers and combines them with the HARQ process to achieve a better power-saving purpose.
[0109] Among them, the LTE DRX process mainly uses the following timers:
[0110] 1. drx-onDurationTimer: The terminal periodically enters the active state to monitor the control channel, as Figure 2 shown.
[0111] 2. Short DRX cycle Timer: To better match the characteristics of data service arrival, the cellular network communication system supports configuring two DRX cycles: short cycle and long cycle. The activation time (on duration timer) of the short cycle and the long cycle is the same, but the sleep time is different. In the short cycle, the sleep time is relatively short, and the terminal can monitor the control channel again faster. The long cycle must be configured and is the initial state of the DRX process, while the short cycle is optional. The Short DRX cycle timer sets the duration of using the short cycle. After the Short cycle timer times out, the terminal will use the long cycle.
[0112] 3. drx-InactivityTimer: After DRX is configured, when the terminal receives the control signaling of the HARQ initial transmission within the time allowed to listen to the control channel (Active Time), this drx-InactivityTimer is started. Before this drx-InactivityTimer expires, the terminal continuously listens to the control channel. If the terminal receives the control signaling of the HARQ initial transmission before the drx-InactivityTimer expires, the drx-InactivityTimer will be terminated and restarted.
[0113] 4. HARQ RTT Timer: It is divided into drx-HARQ-RTT-TimerDL and drx-HARQ-RTT-TimerUL. The purpose is to enable the terminal to stop listening to the control channel before the next retransmission arrives, so as to achieve better power saving. Taking the downlink (DL) as an example, this timer is started when the first symbol after the PUCCH transmission of the terminal-related process starts. If the data in the corresponding HARQ process is not decoded successfully after the previous HARQ transmission (the terminal feedbacks NACK), then after the DL HARQ RTT Timer expires, the terminal will start drx-RetransmissionTimerDL. If the data in the corresponding HARQ process is decoded successfully after the previous HARQ transmission (the terminal feedbacks ACK), after the drx-HARQ-RTT-TimerDL timer expires, the terminal does not start drx-RetransmissionTimerDL. If only drx-HARQ-RTT-TimerDL is running currently, the terminal will no longer listen to the control channel.
[0114] 5. HARQ retransmission Timer: It is divided into drx-RetransmissionTimerDL or drx-RetransmissionTimerUL. Taking the downlink as an example, during the operation of the DL HARQ retransmission Timer, the terminal listens to the control channel and waits for the retransmission scheduling of the corresponding HARQ process.
[0115] As can be seen from the above process, when any of the On duration Timer, HARQ retransmission Timer, and Inactivity Timer is running, the terminal will listen to the control channel. The time when the terminal listens to the control channel can be referred to as Active Time. In the LTE system, the Active Time may be affected by other factors in addition to the DRX timer. In LTE Rel-8, the Active Time of the terminal includes the following times:
[0116] 1) The time when drx-onDurationTimer, or drx-InactivityTimer, or drx-RetransmissionTimerDL, or drx-RetransmissionTimerUL, or ra-ContentionResolutionTimer is running;
[0117] 2) The time waiting for the base station to send the PDCCH after sending the uplink scheduling request (Scheduling Request, abbreviated as SR);
[0118] 3) In the non-competitive random access process, the time waiting for the PDCCH scheduled by the cell radio network temporary identifier (Cell Radio Network Temporary Identifier, abbreviated as C-RNTI) after the terminal receives the random access response message (Random Access Response, abbreviated as RAR).
[0119] Among the above timers, for the short DRX cycle, the onduration calculation formula is as follows:
[0120] [(SFN*10)+subframe number] modulo (shortDRX-Cycle) = (drxStartOffset) modulo (shortDRX-Cycle);
[0121] For the long DRX cycle, the onduration calculation formula is as follows:
[0122] [(SFN*10)+subframe number] modulo (longDRX-Cycle) = drxStartOffset.
[0123] Among them, SFN represents the SFN number of the current radio frame; Subframe number represents the number of the current subframe; shortDRX-Cycle represents the short DRX cycle; longDRX-Cycle represents the long DRX cycle; drxStartOffset represents an offset value configured by RRC signaling.
[0124] Currently, DRX in wireless communication systems is only applicable to the Uu interface between the terminal and the network-side device, and there is no DRX mechanism for the direct communication interface. Among them, the direct communication interface refers to the radio interface corresponding to the direct communication link, and direct communication means that neighboring terminals can perform data transmission within a short distance through a direct communication link or a sidelink, for example, see Figure 3 , Figure 3 which is a schematic diagram of Sidelink communication.
[0125] Among them, the network-side device may be a base station, which may include multiple cells that provide services to terminals. According to different specific application scenarios, the base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network-side device can be used to mutually replace the received air frames and Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an IP communication network. The network-side device can also coordinate the management of the attributes of the air interface. For example, the network-side device can be a network-side device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network-side device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network-side device (evolutional Node B, eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and there is no limitation thereto. In some network architectures, the network-side device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.
[0126] Therefore, in a wireless communication system, in order for the direct communication receiving terminal to successfully receive the data sent by the direct communication sending terminal, it is necessary to monitor the Sidelink between the direct communication receiving terminal and the direct communication sending terminal in real time. As a result, the power consumption of the direct communication receiving terminal will be relatively large.
[0127] Therefore, the embodiments of the present application provide a DRX control method and device for a direct communication interface to address the problem of relatively large power consumption of the direct communication receiving terminal in the related art.
[0128] Among them, the method and the device are based on the same application concept. Since the principles for the method and the device to solve problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be elaborated.
[0129] The DRX control method for a direct communication interface provided by an embodiment of this application is used for a direct communication receiving terminal. By receiving a first status control signaling sent by a first direct communication sending terminal through the direct communication interface, the direct communication receiving terminal enters an active state or a sleep state according to the first status control signaling. Among them, the first direct communication sending terminal sends the first status control signaling to the direct communication receiving terminal within each DRX cycle. Thereby, the direct communication receiving terminal does not need to monitor the Sidelink between the direct communication receiving terminal and the first direct communication sending terminal in real time, so that the power consumption of the direct communication receiving terminal can be reduced.
[0130] The DRX control method, device, terminal, and storage medium for a direct communication interface provided by this application will be described in detail below with reference to the accompanying drawings.
[0131] Figure 4 It is a schematic flowchart of the DRX control method for a direct communication interface provided by Embodiment 1 of this application.
[0132] The execution subject of the embodiment of this application is the DRX control device for a direct communication interface provided by this application. The DRX control device for the direct communication interface can be configured in any direct communication receiving terminal so that the direct communication receiving terminal can execute the DRX control function of the direct communication interface.
[0133] Among them, the direct communication receiving terminal refers to a terminal that receives data based on a direct communication interface. The terminal can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a user equipment (UE for short). The wireless terminal device can communicate with one or more core networks (CN for short) via a radio access network (RAN for short). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. For example, devices such as personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA), etc. The wireless terminal device can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, a user device, which is not limited in the embodiments of this application.
[0134] As Figure 4 shown, the DRX control method of this direct communication interface, which is used for a direct communication receiving terminal, may include the following steps:
[0135] Step 101, receive a first status control signaling sent by a first direct communication sending terminal through the direct communication interface, where the first direct communication sending terminal sends the first status control signaling to the direct communication receiving terminal in each DRX cycle.
[0136] In a possible implementation manner of the embodiment of the present application, the first status control signaling may be a physical layer signaling of a direct communication interface (Sidelink interface, abbreviated as SL interface). For example, the first status control signaling may be identified in the Sidelink Control Information (SCI). For example, one or more bits may be added to the SCI to identify the first status control signaling, or a specific Reference Symbol (RS) may be used to identify the first status control signaling. The present application does not limit this.
[0137] In another possible implementation manner of the embodiment of the present application, the first status control signaling may be a Medium Access Control (MAC) signaling of the direct communication interface. For example, it may be an SL DRX MAC CE (Control Element).
[0138] In yet another possible implementation manner of the embodiment of the present application, the first status control signaling may be a Radio Resource Control (RRC) signaling of the direct communication interface.
[0139] In the embodiment of the present application, the first status control signaling may carry a signaling identifier, such as a signaling ID, which is used to uniquely identify the first status control signaling.
[0140] In the embodiment of the present application, the first status control signaling may be a control signaling based on at least one of the direct communication interface signaling PC5-S link, Access Stratum (AS) connection, per UE, and castype.
[0141] In the embodiment of the present application, the first direct communication sending terminal refers to a terminal that sends data through the direct communication interface. Specifically, the first direct communication sending terminal communicates with the direct communication receiving terminal through the direct communication interface and is used to send data to the direct communication receiving terminal through the direct communication interface.
[0142] In the embodiment of the present application, in each DRX cycle, the first direct communication sending terminal may generate a corresponding first status control signaling according to whether there is data to be sent in a preset future time period, and send the first status control signaling to the direct communication receiving terminal through the direct communication interface in each DRX cycle. Correspondingly, the direct communication receiving terminal may receive the first status control signaling sent by the first direct communication sending terminal through the direct communication interface.
[0143] Step 102: Enter the active state or the sleep state according to the first status control signaling.
[0144] In the embodiment of the present application, during the current DRX cycle, when the direct communication receiving terminal receives the first status control instruction, it can enter the active (Wakeup, abbreviated as W) state or the sleep (Sleep, abbreviated as S) state according to the first status control signaling, so that after the direct communication receiving terminal enters the active state, it listens for the data or signaling sent by the first direct communication sending terminal, or, after the direct communication receiving terminal enters the sleep state, it stops listening for the data or signaling sent by the first direct communication sending terminal, thereby reducing the power consumption of the direct communication receiving terminal. Thus, the direct communication receiving terminal can achieve discontinuous data reception in each DRX cycle to reduce power consumption.
[0145] For example, during the current DRX cycle, when the first direct communication sending terminal has no data to send, the first status control signaling generated by the first direct communication sending terminal can be a sleep signaling, so that the direct communication receiving terminal can enter the sleep state according to the first status control signaling to save power, and when the first direct communication sending terminal has data to send, the first status control signaling generated by the first direct communication sending terminal can be an active signaling, so that the direct communication receiving terminal can enter the active state according to the first status control signaling to improve the success rate of data reception.
[0146] The DRX control method for the direct communication interface in the embodiment of the present application is that the direct communication receiving terminal receives the first status control signaling sent by the first direct communication sending terminal through the direct communication interface and enters the active state or the sleep state according to the first status control signaling, where the first direct communication sending terminal sends the first status control signaling to the direct communication receiving terminal in each DRX cycle. Thus, the direct communication receiving terminal does not need to continuously listen to the Sidelink between the direct communication receiving terminal and the first direct communication sending terminal, thereby reducing the power consumption of the direct communication receiving terminal.
[0147] In a possible implementation manner of the embodiment of the present application, one first status control signaling can be received in each DRX cycle, or multiple first status control signaling can also be received in each DRX cycle, where the first status control signaling can include an active signaling or a sleep signaling. The following will be described in detail with reference to Figure 5a 、 Figure 5b and Figure 7 for detailed description.
[0148] In a possible implementation manner of the embodiment of the present application, a first status control signaling can be received in each DRX cycle. Each DRX cycle can include a timing period, and each first status control signaling can correspond to a timing period. Wherein, the first status control signaling can include an activation signaling or a sleep signaling. After the direct communication receiving terminal receives the first status control signaling during the current DRX cycle, it can determine whether the first status control signaling is an activation signaling or a sleep signaling. If the direct communication receiving terminal determines that the first status control signaling is an activation signaling, it enters the active state during the timing period after receiving the activation signaling and enters the sleep state during other periods of the same DRX cycle. If the direct communication receiving terminal determines that the first status control signaling is a sleep signaling, the direct communication receiving terminal enters the sleep state during the current DRX cycle. The above process will be described in detail below in combination with Embodiment 2.
[0149] Figure 5a It is a schematic flowchart of the DRX control method for the direct communication interface provided in Embodiment 2 of the present application.
[0150] As Figure 5a shown, the DRX control method for the direct communication interface can include the following steps:
[0151] Step 201, receive a first status control signaling sent by a first direct communication sending terminal through the direct communication interface. Wherein, the first direct communication sending terminal sends a first status control signaling to the direct communication receiving terminal in each DRX cycle. One first status control signaling is received in each DRX cycle. The DRX cycle includes a timing period, and each first status control signaling corresponds to a timing period. The first status control signaling includes an activation signaling or a sleep signaling.
[0152] In the embodiment of the present application, one first status control signaling can be received in each DRX cycle, and each DRX cycle can include a timing period. Wherein, each first status control signaling corresponds to a timing period, and this timing period can be, for example, the on duration in the DRX cycle.
[0153] Step 202, determine whether the first status control signaling is an activation signaling or a sleep signaling.
[0154] In the embodiment of the present application, when the direct communication receiving terminal receives the first status control signaling during the current DRX cycle, it can determine whether the first status control signaling received during the current DRX cycle is an activation signaling or a sleep signaling.
[0155] Step 203, if the first status control signaling is activation signaling, enter the active state during the timing period after receiving the activation signaling, and enter the sleep state during other periods of the same DRX cycle.
[0156] In the embodiment of the present application, when the direct communication receiving terminal determines that the first status control signaling received during the current DRX cycle is activation signaling, the direct communication receiving terminal can enter the active state during the timing period after receiving the activation signaling, and enter the sleep state during other periods of the current DRX cycle.
[0157] In a possible implementation manner of the embodiment of the present application, when the direct communication receiving terminal determines that the first status control signaling received during the current DRX cycle is activation signaling, the direct communication receiving terminal can enter the active state during the timing period of the current DRX cycle. For example, the following timer can be started to enter the active state during the timing period: start the SL interface drx-onDurationTimer.
[0158] Step 204, if the first status control signaling is sleep signaling, enter the sleep state during the DRX cycle.
[0159] In the embodiment of the present application, when the direct communication receiving terminal determines that the first status control signaling received during the current DRX cycle is sleep signaling, the direct communication receiving terminal can enter the sleep state during the current DRX cycle.
[0160] In a possible implementation manner of the embodiment of the present application, when the direct communication receiving terminal determines that the first status control signaling received during the current DRX cycle is sleep signaling, the direct communication receiving terminal can quickly enter the sleep state. For example, it can enter the sleep state by stopping at least one of the following timers: stop the SL interface drx-onDurationTimer, stop the SL interface drx-InactivityTimer.
[0161] For example, the first status control signaling can be one bit, used to indicate an activation instruction (W) or a sleep instruction (S). If the first status control signaling received during the current DRX cycle is activation signaling, it can enter the active state during the timing period or the active period (on duration) of the current DRX cycle, and enter the sleep state during other periods.
[0162] As an example, refer to Figure 6 , Figure 6 is a schematic diagram of the configuration method of the first status control signaling in the embodiment of the present application Figure One . Such as Figure 6As shown, in each DRX cycle, a monitoring period for the status control signaling can be designed before the on duration. During this monitoring period, the first direct communication transmitting terminal can generate corresponding first status control signaling based on whether there is data to be sent in a preset future time period. For example, in the first two DRX cycles, since the first direct communication transmitting terminal has data to be sent, it can generate an activation signaling, and the direct communication receiving terminal enters the active state during the on duration (i.e., the timing period) following the monitoring period to monitor the data or signaling sent by the first direct communication transmitting terminal. In the subsequent two DRX cycles, since the first direct communication transmitting terminal has no data to be sent, it can generate a sleep instruction, and the direct communication receiving terminal remains in the sleep state during the on duration following the monitoring period to save power consumption.
[0163] Thus, it can be achieved that during the on duration of the DRX cycle, the direct communication receiving terminal can be controlled to enter the active state (such as Figure 6 the first two DRX cycles in Figure 6 ) to improve the success rate of data reception, and the direct communication receiving terminal can also be controlled to enter the sleep state (such as
[0164] the subsequent two DRX cycles in Figure 6 ) to reduce the power consumption of the direct communication receiving terminal.
[0165] In another possible implementation manner of the embodiment of the present application, each DRX cycle may receive a first status control signaling. Each DRX cycle may include a timing period, and each first status control signaling may correspond to N timing periods. Wherein, the first status control signaling may include an activation signaling or a sleep signaling. After the direct communication receiving terminal receives the first status control signaling during the current DRX cycle, it may determine whether the first status control signaling is an activation signaling or a sleep signaling. If the direct communication receiving terminal determines that the first status control signaling is an activation signaling, it enters the active state during the N timing periods after receiving the activation signaling, and enters the sleep state during other periods of the same DRX cycle. If the direct communication receiving terminal determines that the first status control signaling is a sleep signaling, the direct communication receiving end enters the sleep state during the current DRX cycle and the subsequent N - 1 DRX cycles. The above process will be described in detail below in conjunction with Embodiment 3.
[0166] Figure 5b It is a schematic flowchart of the DRX control method for the direct communication interface provided by Embodiment 3 of the present application.
[0167] As Figure 5b shown, the DRX control method for the direct communication interface may include the following steps:
[0168] Step 301: Receive a first status control signaling sent by a first direct communication sending terminal through the direct communication interface. Wherein, the first direct communication sending terminal sends a first status control signaling to the direct communication receiving terminal during each DRX cycle. Each DRX cycle receives a first status control signaling. The DRX cycle includes a timing period, and each first status control signaling corresponds to N timing periods. The first status control signaling includes an activation signaling or a sleep signaling.
[0169] In the embodiment of the present application, each DRX cycle may receive a first status control signaling, and each DRX cycle may include a timing period. Wherein, each first status control signaling corresponds to N timing periods. The timing period may be, for example, the on duration in the DRX cycle, that is, each first status control signaling may correspond to multiple on durations. Wherein, N is a positive integer greater than 1.
[0170] Step 302: Determine whether the first status control signaling is an activation signaling or a sleep signaling.
[0171] In the embodiment of the present application, when the direct communication receiving terminal receives the first status control signaling during the current DRX cycle, it may determine whether the first status control signaling received during the current DRX cycle is an activation signaling or a sleep signaling.
[0172] Step 303. If the first status control signaling is activation signaling, enter the active state in N timing periods after receiving the activation signaling, and enter the sleep state in other periods of the same DRX cycle.
[0173] In the embodiment of the present application, when the direct communication receiving terminal determines that the first status control signaling received during the current DRX cycle is activation signaling, the direct communication receiving terminal can enter the active state in N timing periods after receiving the activation signaling, and enter the sleep state in other periods of the current DRX cycle. That is to say, during the current DRX cycle and the subsequent N - 1 DRX cycles, it can enter the active state in each on - duration period, and enter the sleep state in other periods.
[0174] Step 304. If the first status control signaling is sleep signaling, enter the sleep state during the DRX cycle and the subsequent N - 1 DRX cycles.
[0175] In the embodiment of the present application, when the direct communication receiving terminal determines that the first status control signaling received during the current DRX cycle is sleep signaling, the direct communication receiving terminal can enter the sleep state during the current DRX cycle and the subsequent N - 1 DRX cycles.
[0176] For example, the first status control signaling can be multi - bit. The first bit can be used to indicate the activation instruction (W) or the sleep instruction (S), and the subsequent bits can be used to indicate the quantity N. If the first status control signaling received during the current DRX cycle is activation signaling, it can enter the active state in the on - duration periods of the current DRX cycle and the subsequent N - 1 DRX cycles, and enter the sleep state in other periods.
[0177] In another possible implementation manner of the embodiment of the present application, each DRX cycle can further include multiple first status control signalings. Among them, the DRX cycle includes multiple timing periods, and each first status control signaling corresponds to one or more timing periods. During each DRX cycle, the direct communication receiving terminal can receive multiple first status control signalings in the DRX cycle, and enter the active state or the sleep state in the timing periods corresponding to the first status control signalings. The following will describe the above process in detail in combination with Embodiment 4.
[0178] Figure 7 It is a flowchart of the DRX control method for the direct communication interface provided by Embodiment 4 of the present application.
[0179] As Figure 7 shown, the DRX control method for the direct communication interface can include the following steps:
[0180] Step 401: Receive a first status control signaling sent by a first direct communication sending terminal through a direct communication interface. Among them, the first direct communication sending terminal sends the first status control signaling to a direct communication receiving terminal in each DRX cycle, and receives multiple first status control signalings in each DRX cycle. The DRX cycle includes multiple timing periods, and each first status control signaling corresponds to one or more timing periods.
[0181] In the embodiments of the present application, multiple first status control signalings can be received in each DRX cycle, and each DRX cycle can include multiple timing periods, and each first status control signaling corresponds to one or more timing periods.
[0182] Step 402: Receive multiple first status control signalings during the DRX cycle.
[0183] In the embodiments of the present application, within the current DRX cycle, the direct communication receiving terminal can receive multiple first status control signalings.
[0184] Step 403: Enter an active state or a sleep state according to the multiple first status control signalings during the timing periods corresponding to the first status control signalings.
[0185] In the embodiments of the present application, during the current DRX cycle, whenever the direct communication receiving terminal receives a first status control signaling, it can enter an active state or a sleep state during the timing period corresponding to the received first status control signaling. Specifically, when the first status control signaling is an active signaling, the direct communication receiving terminal can enter an active state during the timing period corresponding to the first status control signaling, and when the first status control signaling is a sleep signaling, the direct communication receiving terminal can enter a sleep state during the timing period corresponding to the first status control signaling.
[0186] It should be noted that the number of timing periods included in the marked DRX cycle is M. When each first status control signaling corresponds to multiple timing periods, for example, when each status control signaling corresponds to N timing periods, M can be greater than N, or M can be less than N, or M can be equal to N. The present application does not limit this. That is to say, a first status control signaling can correspond to multiple timing periods in one DRX cycle, or the first status control signaling can also correspond to multiple timing periods in multiple DRX cycles.
[0187] In a possible implementation of the embodiment of the present application, the direct communication receiving terminal can enter the active state by starting the following timer: start the drx-onDurationTimer of the SL interface, and enter the sleep state by stopping at least one of the following timers: stop the drx-onDurationTimer of the SL interface, stop the drx-InactivityTimer of the SL interface.
[0188] As an example, taking each first state control signaling corresponding to a timing period for illustration, refer to Figure 8 , Figure 8 which is a schematic diagram of the configuration method of the first state control signaling in the embodiment of the present application. Figure Two . As Figure 8 shown, during the activation period of the on duration of each DRX, multiple monitoring periods of the state control signaling can be configured. During each monitoring period, the first direct communication sending terminal can generate the corresponding first state control signaling according to whether there is data to be sent in a preset future period. For example, in the first two monitoring periods, since the first direct communication sending terminal has data to be sent, it can generate an activation signaling. After receiving the activation signaling, the direct communication receiving terminal is in the active state during the timing period after the monitoring period (a timer is included in the signaling with a fixed duration) to monitor the data or signaling sent by the first direct communication sending terminal. In the last two monitoring periods, since the first direct communication sending terminal has no data to be sent, it can generate a sleep instruction. After receiving the sleep signaling, the direct communication receiving terminal is in the sleep state during the timing period after the monitoring period (a timer is included in the signaling with a fixed duration) to save power.
[0189] It can be seen from Figure 8 that the first state control signaling can be sent or received within one or more time periods after the start of the On duration, and the existing DRX model needs to be modified.
[0190] Therefore, it can be achieved that within the On duration of the same DRX cycle, the direct communication receiving terminal can be controlled to enter the active state (such as Figure 8 the first two monitoring periods in Figure 8 ) to improve the success rate of data reception, and the direct communication receiving terminal can also be controlled to enter the sleep state (such as Figure 8 the last two monitoring periods in Figure 8 ) to reduce the power consumption of the direct communication receiving terminal.
[0191] In a possible implementation manner of the embodiment of the present application, the first direct communication sending terminal may generate first status control signaling configuration information according to its own service data characteristics, and send the first status control signaling configuration information to the direct communication receiving terminal through the direct communication interface. Correspondingly, when the direct communication receiving terminal receives the first status control signaling configuration information, it may monitor the first status control signaling according to the first status control signaling configuration information.
[0192] It should be noted that in actual application, the direct communication receiving terminal may communicate with multiple direct communication sending terminals. When the direct communication receiving terminal communicates with a direct communication sending terminal other than the first direct communication sending terminal, which is denoted as the second direct communication sending terminal in this application, the first direct communication sending terminal and the second direct communication sending terminal may respectively generate first status control signaling configuration information and second status control signaling configuration information according to their own service data characteristics, and respectively send the first status control signaling configuration information and the second status control signaling configuration information to the direct communication receiving terminal through the direct communication interface. After receiving the first status control signaling configuration information and the second status control signaling configuration information, the direct communication receiving terminal may generate union monitoring control information according to the first status control signaling configuration information and the second status control signaling configuration information, and monitor the first status control signaling and the second status control signaling sent by the second direct communication sending terminal according to the union monitoring control information.
[0193] As an example, refer to Figure 9 , Figure 9 which is a schematic diagram of the configuration process of the status control signaling in the embodiment of the present application Figure One . Among them, the direct communication sending terminal configures the status control signaling according to its own service data characteristics. Specifically, the first direct communication sending terminal configures the first status control signaling (for example, marked as control signaling 1) to obtain the first status control signaling configuration information (for example, marked as configuration 1), and sends configuration 1 to the direct communication receiving terminal through the SL interface. After receiving configuration 1, the direct communication receiving terminal may monitor control signaling 1 according to configuration 1. The first direct communication sending terminal may send control signaling 1 according to configuration 1.
[0194] At this time, if there is a new direct communication sending terminal (which may also be referred to as a new L2 source ID), denoted as the second direct communication sending terminal in this application, that also wishes to send data to the direct communication receiving terminal (which may also be referred to as the L2 destination ID), then the second direct communication sending terminal may configure the second status control signaling (for example, marked as control signaling 2) to obtain the second status control signaling configuration information (for example, marked as configuration 2), and send configuration 2 to the direct communication receiving terminal through the SL interface.
[0195] After the direct communication receiving terminal receives Configuration 2 of Control Signaling 2, it can monitor the control signaling according to the union of Configuration 1 and Configuration 2. Thereafter, the first direct communication sending terminal can send Control Signaling 1 according to Configuration 1, and the second direct communication sending terminal can send Control Signaling 2 according to Configuration 2.
[0196] In another possible implementation manner of the embodiments of the present application, the direct communication receiving terminal can also generate its own status control signaling configuration information according to the characteristics of its existing service data, and send the own status control signaling configuration information to the first direct communication sending terminal through the direct communication interface. Correspondingly, when the first direct communication sending terminal receives the own status control signaling configuration information, it can send the first status control signaling according to the own status control signaling configuration information and the characteristics of the service data of the first direct communication sending terminal itself.
[0197] It should be noted that in actual application, the direct communication receiving terminal can communicate with multiple direct communication sending terminals. When the direct communication receiving terminal communicates with a direct communication sending terminal other than the first direct communication sending terminal, which is denoted as the second direct communication sending terminal in this application, the direct communication receiving terminal can also determine whether to configure the status control signaling according to the current configuration and the characteristics of the service data already carried. For example, when the amount of service increases, the direct communication receiving terminal can configure more status control signaling resources, and when the amount of service decreases, the direct communication receiving terminal can configure fewer status control signaling resources. When determining to configure the status control signaling, the above-mentioned own status control signaling configuration information can be updated, and the updated own status control signaling configuration information is sent to the second direct communication sending terminal. After receiving the updated own status control signaling configuration information, the second direct communication sending terminal can send the second status control signaling according to the updated own status control signaling configuration information and the characteristics of its own service data.
[0198] That is to say, the direct communication receiving terminal can send the own status control signaling configuration information to the first direct communication sending terminal and the second direct communication sending terminal respectively. After receiving the own status control signaling configuration information respectively, the first direct communication sending terminal and the second direct communication sending terminal can send the first status control signaling and the second status control signaling respectively according to the characteristics of their own service data and the own status control signaling configuration information.
[0199] As an example, refer to Figure 10 , Figure 10 which is a schematic diagram of the configuration process of the status control signaling in the embodiments of the present application Figure TwoAmong them, the direct communication receiving terminal configures the status control signaling. Specifically, the direct communication receiving terminal can generate its own status control signaling configuration information according to the characteristics of its existing service data, and broadcast the own status control signaling configuration information through the SL interface. After receiving the broadcast own status control signaling configuration information, the first direct communication transmitting terminal can parse the own status control signaling configuration information and send the first status control signaling (such as marked as control signaling 1) in combination with the characteristics of its own service data.
[0200] At this time, if there is a new direct communication transmitting terminal (which can also be called a new L2 source ID), denoted as the second direct communication transmitting terminal in this application, also hopes to send data to the direct communication receiving terminal (which can also be called L2 destination ID), then the direct communication receiving terminal determines whether to configure the status control signaling according to the current configuration and the characteristics of the service data already carried. For example, when the traffic volume increases, the direct communication receiving terminal can configure more status control signaling resources, and when the traffic volume decreases, the direct communication receiving terminal can configure fewer status control signaling resources. When it is determined to configure the status control signaling, the above-mentioned own status control signaling configuration information can be updated and the updated own status control signaling configuration information can be broadcast through the SL interface.
[0201] After receiving the broadcast own status control signaling configuration information, the second direct communication transmitting terminal can parse the own status control signaling configuration information and send the second status control signaling (such as marked as control signaling 2) in combination with the characteristics of its own service data.
[0202] In a possible implementation manner of the embodiment of this application, the first status control signaling or the second status control signaling can be a physical layer signaling of the SL interface (for example, the first status control signaling or the second status control signaling can be identified in the SCI), or can also be a MAC signaling of the SL interface (such as SL DRX MAC CE), or can also be an RRC signaling of the SL interface. For the format design of the first status control signaling or the second status control signaling, it can be a signaling format based on the PC5-S link, and / or an AS layer connection, and / or per UE, and / or castype.
[0203] The embodiment of this application takes the first status control signaling or the first status control signaling as MAC CE as an example for illustration.
[0204] In the first case, for the MAC CE signaling format based on the PC5-S link, the MAC CE corresponds to the MAC sub-header, as Figure 11 shown Figure 11This is a schematic diagram of the MAC CE sub-header in an embodiment of this application. The MAC CE sub-header is 8 bits in total. The first two bits R are reserved bits, and the field Logical channel ID (LCID) is 6 bits long.
[0205] Among them, the MAC CE format instance can be one of the following situations:
[0206] MAC CE format 1: W / S is used to indicate whether the direct communication receiving terminal enters the sleep state or the active state in the next DRX cycle. The Source ID (direct communication sending terminal ID) and Destination ID (direct communication receiving terminal ID) indicate the PC5-S link identifier. As Figure 12 shown, Figure 12 This is Example 1 of the MAC CE format in an embodiment of this application.
[0207] MAC CE format 2: The identifier of PC5-S is identified in the MAC PDU (Protocol Data Unit) sub-header. As Figure 13 and Figure 14 shown, Figure 13 This is Example 2 of the MAC CE format in an embodiment of this application, Figure 14 This is Example 2 of the MAC PDU sub-header in an embodiment of this application. Among them, the length of the field V (Version) is 4 bits, the length of the field SRC (Source) is 2 * 8 = 16 bits, and the length of the field DST (Destination) is 8 bits.
[0208] MAC CE format 3: The identifier of PC5-S is identified in the MAC PDU sub-header. Whether the direct communication receiving terminal enters the active state is indicated by whether this MAC CE is sent. Thus, except for the sub-header, the payload part of the MACCE of the first state control signaling or the second state control signaling is empty.
[0209] The second situation is based on the MAC CE signaling format of the UE. The MAC CE corresponds to the MAC sub-header, as Figure 11 shown.
[0210] Among them, the MAC CE format instance can be one of the following situations:
[0211] MAC CE format 1: W / S is used to indicate whether the direct communication receiving terminal enters the sleep state or the active state in the next DRX cycle. The UE ID identification field is the identifier of the direct communication receiving terminal. As Figure 15 shown, Figure 15This is Example 3 of the MAC CE sub - header in the embodiments of this application.
[0212] MAC CE Format 2: Indicates whether the direct communication receiving terminal enters the active state, which is indicated by whether to send this MAC CE. The UE ID identification field is the identification of the direct communication receiving terminal. As Figure 16 shown, Figure 16 This is Example 4 of the MAC CE sub - header in the embodiments of this application.
[0213] In the embodiments of this application, the first status control signaling or the second status control signaling can be 1 bit, or can also be multiple bits, and this application does not limit this. For example, in the above MAC CE, the first bit W / S can be the first status control signaling or the second status control signaling, where W can refer to the activation signaling and S can refer to the sleep signaling.
[0214] To implement the above - mentioned embodiments, this application also proposes a DRX control method for a direct communication interface.
[0215] Figure 17 This is a schematic flowchart of the DRX control method for the direct communication interface provided in Embodiment 5 of this application.
[0216] The execution subject of the embodiments of this application is the DRX control device for the direct communication interface provided by this application. The DRX control device for the direct communication interface can be configured in any direct communication sending terminal so that the direct communication sending terminal can execute the DRX control function of the direct communication interface. For example, the direct communication sending terminal can be the first direct communication sending terminal in the above - mentioned embodiments, or can also be the second direct communication sending terminal, and this application does not limit this.
[0217] As Figure 17 shown, the DRX control method for the direct communication interface, which is used for the direct communication sending terminal, can include the following steps:
[0218] Step 501, in each DRX cycle, send status control signaling to the direct communication receiving terminal through the direct communication interface, where the status control signaling is used for the direct communication receiving terminal to enter the active state or the sleep state.
[0219] In the embodiments of this application, the status control signaling can be a physical layer signaling of the SL interface (for example, this status control signaling can be identified in the SCI), or a MAC signaling of the SL interface (for example, it can be the SL DRX MAC CE), or an RRC signaling of the SL interface.
[0220] In the embodiments of this application, the status control signaling can carry a signaling identifier, such as a signaling ID, and this signaling identifier is used to uniquely identify the status control signaling.
[0221] In the embodiment of the present application, in each DRX cycle, the direct communication transmitting terminal can generate corresponding status control signaling according to whether there is data to be transmitted in a preset future time period, and during each DRX cycle, send the status control signaling to the direct communication receiving terminal through the direct communication interface. Correspondingly, the direct communication receiving terminal can receive the status control signaling sent by the direct communication transmitting terminal through the direct communication interface, and enter the active state or the sleep state according to the status control signaling. Thus, after the direct communication receiving terminal enters the active state, it can monitor the data or signaling sent by the direct communication transmitting terminal, or after the direct communication receiving terminal enters the sleep state, it can stop monitoring the data or signaling sent by the direct communication transmitting terminal, thereby reducing the power consumption of the direct communication receiving terminal. Therefore, the direct communication receiving terminal can achieve discontinuous data reception in each DRX cycle to reduce power consumption.
[0222] For example, in the current DRX cycle, when the direct communication transmitting terminal has no data to send, the status control signaling generated by the direct communication transmitting terminal can be a sleep signaling, and the direct communication receiving terminal can enter the sleep state according to the status control signaling to save power. When the direct communication transmitting terminal has data to send, the status control signaling generated by the direct communication transmitting terminal can be an activation signaling, so that the direct communication receiving terminal can enter the active state according to the status control signaling to improve the success rate of data reception.
[0223] In a possible implementation manner of the embodiment of the present application, the direct communication transmitting terminal can generate status control signaling configuration information according to its own service data characteristics, and send the status control signaling configuration information to the direct communication receiving terminal through the direct communication interface. Correspondingly, when the direct communication receiving terminal receives the status control signaling configuration information, it can monitor the status control signaling according to the status control signaling configuration information.
[0224] It should be noted that the above Figures 4 to 16 explanation of the steps executed by the direct communication receiving terminal in the embodiment also applies to the steps executed by the direct communication transmitting terminal in this embodiment. The principle is similar and will not be elaborated here.
[0225] The DRX control method for the direct communication interface in the embodiment of the present application is that the direct communication transmitting terminal sends status control signaling to the direct communication receiving terminal through the direct communication interface during each DRX cycle, where the status control signaling is used for the direct communication receiving terminal to enter the active state or the sleep state. Therefore, the direct communication receiving terminal does not need to continuously monitor the Sidelink between the direct communication receiving terminal and the first direct communication transmitting terminal, thereby reducing the power consumption of the direct communication receiving terminal.
