Detailed Description

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Before describing the embodiments of the present application, for the convenience of understanding, first, common technical terms of the present application are introduced:

HARQ refers to Hybrid Automatic Repeat Request (Hybrid Automatic Repeat Request).

DRX refers to Discontinuous Reception (Discontinuous Reception).

PDCCH, Physical Downlink Control Channel (PDCCH).

PUCCH, Physical Uplink Control Channel (Physical Uplink Control Channel).

NACK, negative feedback.

ACK and confirmation.

RRC, Radio Resource Control (Radio Resource Control).

In conventional cellular network communication, as shown in fig. 1, uplink data, downlink data, and control information are transmitted between a terminal (UE) and a network side device through a Uu interface.

In a mobile communication system based on a shared channel, for example, in LTE (Long Term Evolution), transmission of uplink data and downlink data is controlled by a base station (eNB) scheduler, and when the scheduler determines to schedule a certain terminal, the terminal may be notified on what resource to transmit or receive data through a control channel. And the terminal (UE) monitors the control channel, and when the terminal detects that the terminal contains the scheduling information of the terminal, the terminal completes the transmission (uplink) or the reception (downlink) of the data according to the indication on the control channel. When the terminal is in an active state, because the terminal does not determine when the base station scheduler schedules the terminal, a common working mode is that the terminal needs to continuously monitor the control channel and analyze each subframe containing the downlink scheduling control channel to determine whether the subframe is scheduled. The working mode can obtain higher scheduling efficiency under the condition that the terminal has larger data volume and is likely to be frequently scheduled. However, for some services, the frequency of arrival of data is low, resulting in a small number of times that the terminal is scheduled, which will certainly increase the power consumption of the terminal if the terminal is still continuously listening to the control channel.

Therefore, in order to solve the problem of high power consumption of the terminal, the cellular network communication system adopts a DRX operation mode, in which the terminal can periodically monitor the control channel, thereby achieving the purpose of saving power.

The basic principle of DRX is shown in fig. 2, where the On duration indicates a time period during which the terminal monitors the control channel, and in this time period, the radio frequency channel of the terminal is opened and continuously monitors the control channel, and at other times except the On duration, that is, at a time period corresponding to the Opportunity for DRX in fig. 2, the terminal is in a Sleep (Sleep) state, and the radio frequency link thereof is closed and does not monitor the control channel any more, so as to achieve the purpose of saving power. Wherein, the On Duration occurs periodically, and the specific period (cycle) is realized by the base station configuration.

The DRX mechanism of cellular networks takes into account the arrival model of data traffic, i.e. the arrival of data packets is bursty, it being understood that once a data packet arrives, more packets arrive consecutively in a shorter time. In order to adapt to the service arrival characteristics, various timers are adopted in the LTE DRX process and are combined with the HARQ process, so that the aim of better saving the electric quantity is fulfilled.

The LTE DRX process mainly uses the following timers (Timer):

1. drx-onDurationTimer: the terminal periodically enters the active state to listen to the control channel, as shown in fig. 2.

2. Short DRX cycle Timer: for better matching data traffic arrival characteristics, the cellular network communication system supports the configuration of two DRX cycles (DRX cycles): short cycles and long cycles. The short cycle and long cycle have the same activation time (on duration timer) but different sleep times. In the short cycle, the sleep time is relatively short, and the terminal can listen to the control channel again more quickly. The long cycle is mandatory to configure and is the initial state of the DRX procedure, while the short cycle is optional. The Short DRX cycle timer sets the duration of using the Short cycle, and after the Short cycle timer is overtime, the terminal uses the long cycle.

3. drx-inactivytytimer: after configuring DRX, when the terminal receives the control signaling of HARQ initial transmission in the Time (Active Time) allowing to monitor the control channel, the DRX-inactivity timer is opened, and the terminal continuously monitors the control channel before the DRX-inactivity timer is overtime. If the terminal receives the control signaling of the HARQ initial transmission before the drx-InactivatyTimer is overtime, the drx-InactivatyTimer is terminated and restarted.

4. HARQ RTT Timer: and the method is divided into drx-HARQ-RTT-TimerDL and drx-HARQ-RTT-TimerUL. The purpose is to make the terminal possible not to monitor the control channel before the next retransmission comes, thereby achieving the purpose of better saving the electric quantity. Taking Downlink (DL for short) as an example, when the first symbol after PUCCH transmission of the terminal-related process is started, the timer is turned on. If the decoding of the data in the corresponding HARQ process was unsuccessful after the previous HARQ transmission (terminal feeds back NACK), the terminal will open drx-retransmission timerdl after DL HARQ RTT Timer times out. If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission (the terminal feeds back ACK), after the expiration of the drx-HARQ-RTT-TimerDL timer, the terminal does not start drx-retransmission TimerDL. If only drx-HARQ-RTT-TimerDL is currently running, the terminal does not monitor the control channel any more.

5. HARQ retransmission Timer: classified as drx-retransmission timerdl or drx-retransmission timerll. As an example of the following behavior, during the running period of the DL HARQ retransmission Timer, the terminal monitors the control channel and waits for the retransmission scheduling of the corresponding HARQ process.

Through the above process, it can be seen that any one of the On duration Timer, HARQ transmission Timer, and Inactivity Timer is running, and the terminal will monitor the control channel. The Time that the terminal listens to the control channel may 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, and in LTE Rel-8, the Active Time of the terminal includes the following Time:

1) time of run of drx-onDurationTimer or drx-InactivetyTimer or drx-RecransmissionTimerDL or drx-RecransmissionTimeUL or ra-ContentionResolutionTimer;

2) after an uplink Scheduling Request (Scheduling Request, abbreviated as SR) is sent, waiting for the time for the base station to send the PDCCH;

3) in the non-contention Random Access process, after receiving a Random Access Response (RAR), a terminal waits for the time of a PDCCH scheduled by a Cell Radio Network Temporary Identifier (C-RNTI).

In the above timer, for short DRX cycle, the onduration calculation formula is as follows:

[(SFN*10)+subframe number]modulo(shortDRX-Cycle)＝(drxStartOffset)modulo(shortDRX-Cycle)；

for the long DRX cycle, the onduration calculation formula is as follows:

[(SFN*10)+subframe number]modulo(longDRX-Cycle)＝drxStartOffset。

the SFN represents the SFN number of the current wireless frame; subframe number represents the number of the current Subframe; short DRX-Cycle represents a short DRX Cycle; longDRX-Cycle represents a long DRX Cycle; drxStartOffset represents an offset value for RRC signaling configuration.

At present, the DRX of a wireless communication system is only suitable for a Uu interface between a terminal and network side equipment, and a direct communication interface has no DRX mechanism. The direct communication interface refers to a wireless interface corresponding to a direct communication link, and the direct communication refers to a manner in which a neighboring terminal can perform data transmission through the direct communication link or a direct link (Sidelink) in a short distance range, for example, see fig. 3, and fig. 3 is a schematic diagram of the Sidelink communication.

The network side device may be a base station, and the base station may include a plurality of cells for providing services to the terminal. A base station may also be called an access point, or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network-side device may be configured to exchange the received air frame with an Internet Protocol (IP) packet 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 Internet Protocol (IP) communication network. The network side device may also coordinate attribute management for the air interface. For example, the network side device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a network side device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) System, a 5G Base Station (gNB) in a 5G network architecture (next generation System), a Home evolved Node B (HeNB), a relay Node (relay Node), a Home Base Station (pico), or a pico Base Station (not limited thereto). In some network structures, 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.

Therefore, in the wireless communication system, in order to successfully receive the data transmitted by the direct communication transmitting terminal, the direct communication receiving terminal needs to monitor the Sidelink between the direct communication receiving terminal and the direct communication transmitting terminal in real time. This results in a large power consumption of the direct communication reception terminal.

Therefore, the present application provides a DRX control method and apparatus for a direct communication interface, which are used to solve the problem in the related art that power consumption of a direct communication receiving terminal is large.

The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

The DRX control method of a direct communication interface according to an embodiment of the present application is used for a direct communication receiving terminal to enter an active state or a dormant state according to a first state control signaling sent by a first direct communication sending terminal through the direct communication interface by receiving the first state control signaling, where the first direct communication sending terminal sends the first state control signaling to the direct communication receiving terminal in each DRX cycle. Therefore, 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, and the power consumption of the direct communication receiving terminal can be reduced.

The DRX control method, apparatus, terminal, and storage medium of the direct communication interface provided in the present application are described in detail below with reference to the accompanying drawings.

Fig. 4 is a flowchart illustrating a DRX control method of a direct communication interface according to an embodiment of the present disclosure.

The main implementation of the embodiments of the present application is the DRX control apparatus of the direct communication interface provided in the present application, and the DRX control apparatus of the direct communication interface may be configured in any direct communication receiving terminal, so that the direct communication receiving terminal may perform the DRX control function of the direct communication interface.

The direct communication receiving terminal refers to a terminal for receiving data based on a direct communication interface, and the terminal may be a device for providing voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be referred to as a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile phone (or "cellular" phone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CN) via a Radio Access Network (RAN). For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs) are used. The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application.

As shown in fig. 4, the DRX control method of the direct communication interface, for a direct communication receiving terminal, may include the steps of:

step 101, receiving a first state control signaling sent by a first direct communication sending terminal through a direct communication interface, wherein the first direct communication sending terminal sends the first state control signaling to a direct communication receiving terminal in each DRX cycle.

In a possible implementation manner of the embodiment of the present application, the first state Control signaling may be physical layer signaling of a direct communication interface (sildenk interface, abbreviated as SL interface), for example, the first state Control signaling may be identified in direct communication interface Control Information (sildenk Control Information, abbreviated as SCI), for example, one bit or multiple bits may be added to SCI to identify the first state Control signaling, or a specific Reference Symbol (Reference Symbol, abbreviated as RS) may also be used to identify the first state Control signaling, which is not limited in this application.

In another possible implementation manner of the embodiment of the present application, the first state Control signaling may be a Medium Access Control (MAC) signaling of the direct communication interface, for example, may be a SL DRX MAC CE (Control Element).

In another possible implementation manner of the embodiment of the present application, the first state Control signaling may be Radio Resource Control (RRC) signaling of the direct communication interface.

In this embodiment of the present application, the first state control signaling may carry a signaling identifier, such as a signaling ID, where the signaling identifier is used to uniquely identify the first state control signaling.

In this embodiment of the application, the first status control signaling may be a control signaling based on at least one of a direct communication interface signaling PC5-S link, an Access Stratum (AS) connection, a terminal (per UE), and a propagation type (category).

In this embodiment, the first direct communication sending terminal refers to a terminal that sends data through the direct communication interface, and specifically, the first direct communication sending terminal communicates with the direct communication receiving terminal through the direct communication interface, and is used for sending data to the direct communication receiving terminal through the direct communication interface.

In this embodiment of the application, in each DRX cycle, the first direct communication sending terminal may generate a corresponding first state control signaling according to whether there is data to be sent in a future preset time period, and in each DRX cycle, send the first state control signaling to the direct communication receiving terminal through the direct communication interface, and correspondingly, the direct communication receiving terminal may receive the first state control signaling sent by the first direct communication sending terminal through the direct communication interface.

Step 102, entering an active state or a dormant state according to the first state control signaling.

In this embodiment of the application, in the DRX cycle, after the direct communication receiving terminal receives the first state control instruction, the direct communication receiving terminal may enter an active (Wakeup, for short, W) state or a Sleep (Sleep, for short, S) state according to the first state control instruction, so as to monitor data or signaling sent by the first direct communication sending terminal after the direct communication receiving terminal enters the active state, or stop monitoring data or signaling sent by the first direct communication sending terminal after the direct communication receiving terminal enters the Sleep state, thereby reducing the power consumption of the direct communication receiving terminal. Therefore, the direct communication receiving terminal can realize discontinuous data reception in each DRX period so as to reduce power consumption.

For example, in the DRX cycle, when the first direct communication sending terminal does not send data, the first state control signaling generated by the first direct communication sending terminal may be a sleep signaling, so that the direct communication receiving terminal may enter a sleep state according to the first state control signaling to save electric power, and when the first direct communication sending terminal sends data, the first state control signaling generated by the first direct communication sending terminal may be an active signaling, so that the direct communication receiving terminal may enter an active state according to the first state control signaling to improve a success rate of receiving data.

According to the DRX control method of the direct communication interface, the direct communication receiving terminal receives a first state control signaling sent by a first direct communication sending terminal through the direct communication interface, and the first state control signaling enters an active state or a dormant state according to the first state control signaling, wherein the first direct communication sending terminal sends the first state control signaling to the direct communication receiving terminal in each DRX period. Therefore, 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, and the power consumption of the direct communication receiving terminal can be reduced.

In a possible implementation manner of the embodiment of the present application, each DRX cycle may receive one first state control signaling, or each DRX cycle may also receive a plurality of first state control signaling, where the first state control signaling may include active signaling or dormant signaling. This is explained in detail below with reference to fig. 5a, 5b and 7.

In a possible implementation manner of the embodiment of the present application, each DRX cycle may receive a first state control signaling, each DRX cycle may include a timing period, and each first state control signaling may correspond to a timing period, where the first state control signaling may include an active signaling or a dormant signaling, and after the direct communication receiving terminal receives the first state control signaling in the DRX cycle, the direct communication receiving terminal may determine whether the first state control signaling is the active signaling or the dormant signaling, and if the direct communication receiving terminal determines that the first state control signaling is the active signaling, the direct communication receiving terminal enters the active state in the timing period after receiving the active signaling, and enters the dormant state in other periods of the same DRX cycle. And if the direct communication receiving terminal determines that the first state control signaling is the dormant signaling, the direct communication receiving terminal enters the dormant state in the DRX period. The above process is described in detail with reference to the second embodiment.

Fig. 5a is a flowchart illustrating a DRX control method of a direct communication interface according to a second embodiment of the present application.

As shown in fig. 5a, the DRX control method of the direct communication interface may include the steps of:

step 201, receiving a first state control signaling sent by a first direct communication sending terminal through a direct communication interface, wherein the first direct communication sending terminal sends the first state control signaling to a direct communication receiving terminal in each DRX cycle, each DRX cycle receives one first state control signaling, the DRX cycle includes a timing period, each first state control signaling corresponds to one timing period, and the first state control signaling includes an active signaling or a dormant signaling.

In this embodiment, each DRX cycle may receive one first state control signaling, and each DRX cycle may include one timing period, where each first state control signaling corresponds to one timing period, and the timing period may be, for example, an active period (on duration) in the DRX cycle.

Step 202, determining that the first state control signaling is an active signaling or a dormant signaling.

In the embodiment of the application, after the direct communication receiving terminal receives the first state control signaling in the current DRX cycle, it may be determined whether the first state control signaling received in the current DRX cycle is an active signaling or a dormant signaling.

In step 203, if the first state control signaling is active signaling, the active state is entered at a timing period after the active signaling is received, and the sleep state is entered at other periods of the same DRX cycle.

In this embodiment, when the direct communication receiving terminal determines that the first state control signaling received in the current DRX cycle is an active signaling, the direct communication receiving terminal may enter an active state at a timing period after receiving the active signaling, and enter a dormant state at other periods of the current DRX cycle.

In a possible implementation manner of the embodiment of the present application, when the direct communication receiving terminal determines that the first state control signaling received in the current DRX cycle is an active signaling, the direct communication receiving terminal may enter the active state at a timing period of the current DRX cycle, for example, the following timer may be started, and enter the active state at the timing period: the SL interface drx onDurationTimer is started.

Step 204, if the first state control signaling is the sleep signaling, entering into the sleep state in the DRX period.

In this embodiment, when the direct communication receiving terminal determines that the first state control signaling received in the current DRX cycle is a dormant signaling, the direct communication receiving terminal may enter a dormant state in the current DRX cycle.

In a possible implementation manner of the embodiment of the present application, when the direct communication receiving terminal determines that the first state control signaling received in the current DRX cycle is a sleep signaling, the direct communication receiving terminal may quickly enter the sleep state, for example, enter the sleep state by stopping at least one of the following timers: the SL interface drx-onDurationTimer is stopped, the SL interface drx-inactivtytimer is stopped.

For example, the first state control signaling may be a bit for indicating an active command (W) or a sleep command (S), and if the first state control signaling received in the current DRX cycle is an active signaling, the first state control signaling may enter the active state during a timing period or an active period (on duration) of the current DRX cycle, and enter the sleep state during other periods.

As an example, referring to fig. 6, fig. 6 is a schematic diagram illustrating a configuration manner of a first state control signaling in an embodiment of the present application. As shown in fig. 6, in each DRX cycle, a monitoring period of the state control signaling may be designed before the on duration, and in the monitoring period, the first direct communication transmitting terminal may generate a corresponding first state control signaling according to whether there is data to be transmitted in a future preset period, for example, in the first two DRX cycles, the first direct communication transmitting terminal may generate an active signaling because there is data to be transmitted, and the direct communication receiving terminal enters an active state in the on duration (i.e., the timing period) after the monitoring period to monitor the data or the signaling transmitted by the first direct communication transmitting terminal. In the latter two DRX cycles, the first direct communication transmitting terminal may generate a sleep command because no data needs to be transmitted, and the direct communication receiving terminal is still in a sleep state during the on duration after the monitoring period, so as to save power consumption.

Therefore, the On duration of the DRX cycle can be realized, and the direct communication receiving terminal can be controlled to enter the active state (for example, the first two DRX cycles in fig. 6) to improve the success rate of data reception, and can be controlled to enter the dormant state (for example, the last two DRX cycles in fig. 6) to reduce the power consumption of the direct communication receiving terminal.

In a possible implementation manner of the embodiment of the present application, the first direct signaling sending terminal may send the first state control signaling at a first signaling sending time in the DRX cycle. The first signaling sending time may be located in a monitoring period, and the monitoring period is located before the timing period, that is, the first signaling sending time is not located in the timing period, so that the direct communication receiving terminal can be prevented from being influenced to successfully receive the service data. For example, referring to fig. 6, a first signaling transmission time may be set between the start time of the DRX cycle and the start time of the timing period On duration, that is, the first signaling transmission time may be set during the monitoring period before the On duration of each DRX cycle to transmit the first state control signaling at the first signaling transmission time, so that the existing DRX model may not be affected.

In another possible implementation manner of the embodiment of the present application, each DRX cycle may receive a first state control signaling, each DRX cycle may include a timing period, and each first state control signaling may correspond to N timing periods, where the first state control signaling may include an active signaling or a dormant signaling, and after the direct communication receiving terminal receives the first state control signaling in the DRX cycle, the direct communication receiving terminal may determine whether the first state control signaling is the active signaling or the dormant signaling, and if the direct communication receiving terminal determines that the first state control signaling is the active signaling, the direct communication receiving terminal enters the active state in N timing periods after receiving the active signaling, and enters the dormant state in other periods of the same DRX cycle. And if the direct communication receiving terminal determines that the first state control signaling is the dormant signaling, the direct communication receiving terminal enters the dormant state in the current DRX period and the subsequent N-1 DRX periods. The above process is described in detail with reference to example three.

Fig. 5b is a flowchart illustrating a DRX control method of a direct communication interface according to a third embodiment of the present application.

As shown in fig. 5b, the DRX control method of the direct communication interface may include the steps of:

step 301, receiving a first state control signaling sent by a first direct communication sending terminal through a direct communication interface, where the first direct communication sending terminal sends the first state control signaling to a direct communication receiving terminal in each DRX cycle, each DRX cycle receives one first state control signaling, the DRX cycle includes a timing period, each first state control signaling corresponds to N timing periods, and the first state control signaling includes an active signaling or a dormant signaling.

In this embodiment of the present application, each DRX cycle may receive one first state control signaling, and each DRX cycle may include one timing period, where each first state control signaling corresponds to N timing periods, and the timing period may be, for example, an active period (on duration) in the DRX cycle, that is, each first state control signaling may correspond to multiple active periods. Wherein N is a positive integer greater than 1.

Step 302, determine the first state control signaling as an active signaling or a dormant signaling.

In the embodiment of the present application, after the direct communication receiving terminal receives the first state control signaling in the DRX cycle of this time, it may be determined whether the first state control signaling received in the DRX cycle of this time is an active signaling or a dormant signaling.

Step 303, if the first state control signaling is active signaling, entering an active state at N timing periods after receiving the active signaling, and entering a sleep state at other periods of the same DRX cycle.

In this embodiment, when the direct communication receiving terminal determines that the first state control signaling received in the current DRX cycle is an active signaling, the direct communication receiving terminal may enter an active state at N timing periods after receiving the active signaling, and enter a dormant state at other periods of the current DRX cycle. That is, the active state may be entered at each timing period (on duration) and the sleep state may be performed at other periods among the present DRX cycle and the subsequent N-1 DRX cycles.

Step 304, if the first state control signaling is sleep signaling, entering into a sleep state in the DRX period and the subsequent N-1 DRX periods.

In the embodiment of the present application, when the direct communication receiving terminal determines that the first state control signaling received in the current DRX cycle is the dormant signaling, the direct communication receiving terminal may enter the dormant state in the current DRX cycle and the subsequent N-1 DRX cycles.

For example, the first status control signaling may be a plurality of bits, the first bit may be used to indicate an activation command (W) or a sleep command (S), and the following bits may be used to indicate the number N. If the first state control signaling received by the current DRX period is an active signaling, the active state can be entered in the current DRX period and the timing period (on duration) of the subsequent N-1 DRX periods, and the dormant state can be entered in other periods.

In yet another possible implementation manner of the embodiment of the present application, each DRX cycle may further include a plurality of first state control signaling, where the DRX cycle includes a plurality of timing periods, and each first state control signaling corresponds to one or more timing periods, and in each DRX cycle, the direct communication receiving terminal may receive the plurality of first state control signaling in the DRX cycle, and enter an active state or a dormant state in the timing period corresponding to the first state control signaling according to the plurality of first state control signaling. The above process is described in detail with reference to example four.

Fig. 7 is a flowchart illustrating a DRX control method of a direct communication interface according to a fourth embodiment of the present application.

As shown in fig. 7, the DRX control method of the direct communication interface may include the steps of:

step 401, receiving a first state control signaling sent by a first direct communication sending terminal through a direct communication interface, where the first direct communication sending terminal sends the first state control signaling to a direct communication receiving terminal in each DRX cycle, each DRX cycle receives multiple first state control signaling, and the DRX cycle includes multiple timing periods, and each first state control signaling corresponds to one or multiple timing periods.

In an embodiment of the present application, each DRX cycle may receive a plurality of first state control signaling, and each DRX cycle may include a plurality of timing periods, each first state control signaling corresponding to one or more timing periods.

Step 402, a plurality of first state control signaling is received during a DRX cycle.

In this embodiment of the present application, within the DRX cycle, the direct communication receiving terminal may receive a plurality of first state control signaling.

And step 403, entering an active state or a dormant state in a timing period corresponding to the first state control signaling according to the plurality of first state control signaling.

In this embodiment, in the DRX cycle, each time the direct communication receiving terminal receives the first state control signaling, the direct communication receiving terminal may enter an active state or a dormant state in a timing period corresponding to the first state control signaling according to the received first state control signaling. Specifically, when the first state control signaling is active signaling, the direct communication receiving terminal may enter an active state during a timing period corresponding to the first state control signaling, and when the first state control signaling is dormant signaling, the direct communication receiving terminal may enter a dormant state during a timing period corresponding to the first state control signaling.

It should be noted that, the number of the timing periods included in the DRX cycle is denoted by M, and when each first state control signaling corresponds to multiple timing periods, for example, each state control signaling corresponds to N timing periods, M may be greater than N, or M may be smaller than N, or M may be equal to N, which is not limited in this application. That is, one first state control signaling may correspond to a plurality of timing periods in one DRX cycle, or the first state control signaling may correspond to a plurality of timing periods in a plurality of DRX cycles.

In a possible implementation manner of the embodiment of the present application, the direct communication receiving terminal may enter the active state by starting the following timer: starting the SL interface drx onDuration timer, entering the sleep state by stopping at least one of the following timers: the SL interface drx-onDurationTimer is stopped, the SL interface drx-inactivtytimer is stopped.

As an example, each first state control signaling corresponds to one timing period, see fig. 8, where fig. 8 is a schematic diagram illustrating a configuration manner of the first state control signaling in this embodiment of the present application. As shown in fig. 8, in the active period of the on duration of each DRX, a plurality of monitoring periods of the status control signaling may be configured, and in each monitoring period, 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 future preset period, for example, in the first two monitoring periods, the first direct communication sending terminal may generate an active signaling because there is data to be sent, and after receiving the active signaling, the direct communication receiving terminal is in an active state in a timing period (the signaling with a fixed duration includes a timer) after the monitoring period, so as to monitor the data or the signaling sent by the first direct communication sending terminal. In the following two monitoring periods, the first direct communication sending terminal can generate a sleep instruction because no data needs to be sent, and the direct communication receiving terminal is in a sleep state in a timing period (a fixed-duration signaling contains a timer) after the monitoring period after receiving the sleep signaling, so as to save power.

As can be seen from fig. 8, the first state control signaling may be sent or received within one or more time periods after the On duration begins, and the existing DRX model needs to be modified.

Therefore, the On duration of the same DRX period can be realized, the direct communication receiving terminal can be controlled to enter the active state (for example, the first two monitoring periods in fig. 8) so as to improve the success rate of data receiving, and the direct communication receiving terminal can be controlled to enter the dormant state (for example, the last two monitoring periods in fig. 8) so as to reduce the power consumption of the direct communication receiving terminal.

In a possible implementation manner of the embodiment of the present application, the first direct communication terminal may generate the first state control signaling configuration information according to the service data characteristics of the first direct communication terminal, and send the first state control signaling configuration information to the direct communication receiving terminal through the direct communication interface, and accordingly, after the direct communication receiving terminal receives the first state control signaling configuration information, the first state control signaling may be monitored according to the first state control signaling configuration information.

It should be noted that, in practical application, the direct communication receiving terminal may communicate with a plurality of direct communication transmitting terminals, when the direct communication receiving terminal communicates with other direct communication transmitting terminals except the first direct communication transmitting terminal, which is denoted as the second direct communication transmitting terminal in this application, the first direct communication transmitting terminal and the second direct communication transmitting terminal may generate the first state control signaling configuration information and the second state control signaling configuration information according to the service data characteristics thereof, and transmit the first state control signaling configuration information and the second state control signaling configuration information to the direct communication receiving terminal through the direct communication interface, respectively, after receiving the first state control signaling configuration information and the second state control signaling configuration information, the direct communication receiving terminal may generate and collect the monitoring control information according to the first state control signaling configuration information and the second state control signaling configuration information, and monitoring the first state control signaling and the second state control signaling sent by the second direct communication sending terminal according to the union monitoring control information.

As an example, referring to fig. 9, fig. 9 is a first schematic configuration flow diagram of state control signaling in an embodiment of the present application. Specifically, the first direct communication sending terminal configures a first state control signaling (for example, marked as control signaling 1), obtains first state 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 transmission terminal may perform transmission of the control signaling 1 according to the configuration 1.

At this time, if there is a new direct communication transmitting terminal (may also be referred to as a new L2 source ID) and it is noted in this application that the second direct communication transmitting terminal also desires to transmit data to the direct communication receiving terminal (may also be referred to as an L2 destination ID), the second direct communication transmitting terminal may configure the second state control signaling (for example, marked as control signaling 2), obtain the second state control signaling configuration information (for example, marked as configuration 2), and transmit configuration 2 to the direct communication receiving terminal through the SL interface.

After receiving configuration 2 of control signaling 2, the direct communication receiving terminal may monitor the control signaling according to the union of configuration 1 and configuration 2. Thereafter, the first direct communication transmitting terminal may transmit the control signaling 1 according to the configuration 1, and the second direct communication transmitting terminal may transmit the control signaling 2 according to the configuration 2.

In another possible implementation manner of the embodiment of the present application, the direct communication receiving terminal may further generate self-state control signaling configuration information according to the existing service data characteristics of the direct communication receiving terminal, and send the self-state control signaling configuration information to the first direct communication sending terminal through the direct communication interface.

It should be noted that, in practical application, the direct communication receiving terminal may communicate with a plurality of direct communication transmitting terminals, and when the direct communication receiving terminal communicates with other direct communication transmitting terminals except the first direct communication transmitting terminal, which is referred to as a second direct communication transmitting terminal in this application, the direct communication receiving terminal may further determine whether to perform configuration of the state control signaling according to the current configuration and characteristics of currently-carried service data, for example, when the traffic volume becomes larger, the direct communication receiving terminal may configure more state control signaling resources, and when the traffic volume becomes smaller, the direct communication receiving terminal may configure less state control signaling resources. When determining to configure the state control signaling, the second direct communication sending terminal may update the self state control signaling configuration information, and send the updated self state control signaling configuration information to the second direct communication sending terminal, and after receiving the updated self state control signaling configuration information, the second direct communication sending terminal may send the second state control signaling according to the updated self state control signaling configuration information and the self service data characteristics.

That is, the direct communication receiving terminal may send the self-state control signaling configuration information to the first direct communication sending terminal and the second direct communication sending terminal, and after receiving the self-state control signaling configuration information, the first direct communication sending terminal and the second direct communication sending terminal may send the first state control signaling and the second state control signaling according to the self-service data characteristics and the self-state control signaling configuration information, respectively.

As an example, referring to fig. 10, fig. 10 is a schematic view illustrating a configuration flow of state control signaling in an embodiment of the present application. Specifically, the direct communication receiving terminal may generate self-state control signaling configuration information according to the existing service data characteristics of the direct communication receiving terminal, and broadcast the self-state control signaling configuration information through the SL interface, and after receiving the broadcasted self-state control signaling configuration information, the first direct communication sending terminal may parse the self-state control signaling configuration information, and send the first state control signaling (for example, marked as control signaling 1) by combining the service data characteristics of the first direct communication sending terminal.

At this time, if there is a new direct communication transmitting terminal (may also be referred to as a new L2 source ID), and it is stated in this application that the second direct communication transmitting terminal also desires to transmit data to the direct communication receiving terminal (may also be referred to as an L2 destination ID), the direct communication receiving terminal determines whether to perform the configuration of the status control signaling according to the current configuration and the characteristics of the currently carried traffic data, for example, when the traffic volume is large, the direct communication receiving terminal may configure a large amount of status control signaling resources, and when the traffic volume is small, the direct communication receiving terminal may configure a small amount of status control signaling resources. When determining to configure the state control signaling, the configuration information of the self state control signaling may be updated, and the updated configuration information of the self state control signaling may be broadcast through the SL interface.

After receiving the broadcasted self-state control signaling configuration information, the second direct communication sending terminal may analyze the self-state control signaling configuration information, and send a second state control signaling (for example, marked as control signaling 2) in combination with the characteristics of the self-service data.

In a possible implementation manner of the embodiment of the present application, the first state control signaling or the second state control signaling may be physical layer signaling of the SL interface (for example, the first state control signaling or the second state control signaling may be identified at the SCI), or may also be MAC signaling of the SL interface (for example, the SL DRX MAC CE), or may also be RRC signaling of the SL interface. For the format design of the first status control signaling or the second status control signaling, a signaling format based on the PC5-S link, and/or an AS layer connection, and/or per UE, and/or a cast type may be used.

In the embodiment of the present application, a first state control signaling or a first state control signaling is taken as an example of a MAC CE.

In the first case, based on the MAC CE signaling format of the PC5-S link, the MAC CE corresponds to the MAC subheader, as shown in fig. 11, fig. 11 is a schematic diagram of the MAC CE subheader in the embodiment of the present application. The MAC CE subheader has 8 bits, the first two bits R are reserved bits, and the length of a field Logical Channel ID (LCID) is 6 bits.

Wherein, the MAC CE format example can be one of the following cases:

MAC CE format 1: the W/S is used for indicating the direct communication receiving terminal to enter a dormant state or an active state in the next DRX period, and the Source ID (direct communication sending terminal ID) and the Destination ID (direct communication receiving terminal ID) indicate the PC5-S link identification. As shown in fig. 12, fig. 12 is a MAC CE format example 1 in the embodiment of the present application.

MAC CE format 2: the identity of PC5-S is identified in the MAC PDU (Protocol Data Unit) subheader. As shown in fig. 13 and fig. 14, fig. 13 is a MAC CE format example 2 in the embodiment of the present application, and fig. 14 is a MAC PDU subheader example 2 in the embodiment of the present application. The length of the field V (Version) is 4 bits, the length of the field SRC (Source address) is 2 × 8 to 16 bits, and the length of the field DST (Destination address) is 8 bits.

MAC CE format 3: the identity of the PC5-S is identified in the subheader of the MAC PDU, and whether the direct communication receiving terminal enters the active state is indicated by whether the MAC CE is transmitted, so that the MAC CE of the first status control signaling or the second status control signaling has its payload part empty except for the subheader.

In the second case, based on the signaling format of the MAC CE of the UE, the MAC CE corresponds to the MAC subheader, as shown in fig. 11.

Wherein, the MAC CE format example can be one of the following cases:

MAC CE format 1: the W/S is used for indicating the direct communication receiving terminal to enter a dormant state or an active state in the next DRX period, and the UE ID identification field is the identification of the direct communication receiving terminal. As shown in fig. 15, fig. 15 is a MAC CE subheader example 3 in the embodiment of the present application.

MAC CE format 2: and indicating whether the direct communication receiving terminal enters an activated state or not, wherein whether the MAC CE is sent or not is indicated, and the UE ID identification field is the identification of the direct communication receiving terminal. As shown in fig. 16, fig. 16 is an example 4 of a MAC CE subheader in the embodiment of the present application.

In this embodiment of the present application, the first state control signaling or the second state control signaling may be 1 bit, or may also be multiple bits, which is not limited in this application. For example, in the MAC CE, the first bit W/S may be a first state control signaling or a second state control signaling, where W may refer to an active signaling and S may refer to a sleep signaling.

In order to implement the above embodiments, the present application further provides a DRX control method of a direct communication interface.

Fig. 17 is a flowchart illustrating a DRX control method of a direct communication interface according to a fifth embodiment of the present application.

The main implementation of the embodiments of the present application is the DRX control apparatus of the direct communication interface provided in the present application, and the DRX control apparatus of the direct communication interface may be configured in any direct communication sending terminal, so that the direct communication sending terminal may perform the DRX control function of the direct communication interface. For example, the direct communication transmitting terminal may be the first direct communication transmitting terminal in the above embodiment, or may be the second direct communication transmitting terminal, and the present application is not limited thereto.

As shown in fig. 17, the DRX control method of the direct communication interface, for a direct communication transmitting terminal, may include the steps of:

step 501, in each DRX cycle, sending a state control signaling to the direct communication receiving terminal through the direct communication interface, where the state control signaling is used for the direct communication receiving terminal to enter an active state or a dormant state.

In this embodiment of the application, the status control signaling may be physical layer signaling of the SL interface (for example, the status control signaling may be identified in the SCI), or MAC signaling of the SL interface (for example, the status control signaling may be SL DRX MAC CE), or RRC signaling of the SL interface.

In this embodiment of the present application, the state control signaling may carry a signaling identifier, such as a signaling ID, where the signaling identifier is used to uniquely identify the state control signaling.

In the embodiment of the present application, in each DRX cycle, the direct communication transmitting terminal may generate a corresponding state control signaling according to whether there is data to be transmitted in a future preset time period, and in each DRX cycle, the state control signaling is sent to the direct communication receiving terminal through the direct communication interface, correspondingly, the direct communication receiving terminal can receive the state control signaling sent by the direct communication sending terminal through the direct communication interface so as to enter an activated state or a dormant state according to the state control signaling, so that after the direct communication receiving terminal enters the activated state, it can monitor the data or signaling sent by the direct communication sending terminal, or alternatively, after the direct communication receiving terminal enters the dormant state, monitoring of data or signaling sent by the direct communication sending terminal can be stopped, so that the power consumption of the direct communication receiving terminal is reduced. Therefore, the direct communication receiving terminal can realize discontinuous data reception in each DRX period so as to reduce power consumption.

For example, in this DRX cycle, when the direct communication sending terminal does not send data, the state control signaling generated by the direct communication sending terminal may be a dormant signaling, and the direct communication receiving terminal may enter the dormant state according to the state control signaling to save power, and when the direct communication sending terminal has data to send, the state control signaling generated by the direct communication sending terminal may be an active signaling, so that the direct communication receiving terminal may enter the active state according to the state control signaling to improve a success rate of data reception.

In a possible implementation manner of the embodiment of the present application, the direct communication sending terminal may generate the state control signaling configuration information according to the service data characteristics of the direct communication sending terminal, and send the state control signaling configuration information to the direct communication receiving terminal through the direct communication interface, and accordingly, after the direct communication receiving terminal receives the state control signaling configuration information, the direct communication receiving terminal may monitor the state control signaling according to the state control signaling configuration information.

It should be noted that the explanation of the steps executed by the direct communication receiving terminal in the embodiments of fig. 4 to fig. 16 also applies to the steps executed by the direct communication sending terminal in the embodiments, and the principle is similar, and is not described herein again.

In the DRX control method of a direct communication interface according to the embodiment of the present application, a direct communication sending terminal sends a state control signaling to a direct communication receiving terminal through the direct communication interface in each DRX cycle, where the state control signaling is used for the direct communication receiving terminal to enter an active state or a dormant state. Therefore, 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, and the power consumption of the direct communication receiving terminal can be reduced.
