Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the like or similar elements throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present application and should not be construed as limiting the present application.

It should be noted that, in the related art, as shown in fig. 1, for a Cellular Mobile Communication System (Cellular Mobile Communication System), a terminal (including a User Equipment 1 (UE) and a UE 2) and a network side device generally transmit uplink/downlink data and control information through a Uu interface. Wherein, the Uu interface is an air interface, also called a wireless interface.

In a mobile communication system based on a shared channel, for example, in Long Term Evolution (LTE) of the universal mobile telecommunications technology, transmission of uplink and downlink data is controlled by a base station (eNB) scheduler. When the scheduler determines to schedule a user, the terminal will be informed via the control channel on what resource to transmit or receive data. 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. In the active state, since the terminal does not determine when the eNB schedules the eNB, a common working mode is that the terminal continuously monitors the control channel and parses each subframe containing its downlink scheduling control channel to determine whether to be scheduled.

However, this operation method can achieve higher efficiency in the case that the terminal has a larger data size and may be frequently scheduled. In particular, for some services, the frequency of arrival of data is low, resulting in a small number of times that the terminal is scheduled, which undoubtedly increases its power consumption if the terminal is still continuously listening to the control channel. In order to solve the problem of power consumption, the cellular network communication system adopts a DRX operation mode, in which the terminal periodically monitors the control channel, thereby achieving the purpose of power saving.

The basic operation principle of DRX is explained below.

As shown in fig. 2, the On Duration represents a time period during which the UE monitors (Monitor) a Control Channel (PDCCH), during which the radio frequency Channel is opened and continuously monitors the Control Channel, and at other times except the On Duration, the UE is in a Sleep state, the radio frequency link of the UE is closed and does not Monitor the Control Channel any more, so as to achieve the purpose of saving power.

The Discontinuous Reception (DRX) mechanism of cellular networks takes into account the arrival model of data traffic, i.e. the arrival of data packets is bursty. That is, once a data packet arrives, more packets arrive consecutively in a shorter time. Therefore, in order to adapt to the service arrival characteristics, the LTE DRX process employs multiple timers and is combined with a Hybrid Automatic Repeat reQuest (HARQ) process, so as to achieve better power saving performance.

The basic principle of direct communication (SL) is explained below.

As shown in fig. 3, SL refers to a manner in which neighboring terminals can perform data transmission through a direct communication link (also referred to as Sidelink) in a short range. The wireless interface corresponding to the Sidelink link is called a direct communication interface, also called a Sidelink interface, and is called an SL interface for short.

For the Next generation radio access (NR) car networking (V2X) as an example, in NR V2X, there are three types of SL traffic, unicast, multicast, and broadcast.

The PC5 connection establishment procedure is directed only to unicast communication. The process of PC5 connection establishment is done through a PC5-S signaling interaction process. That is, SA 2V 2X layer also has no connection establishment procedure for multicast communication. Therefore, in V2X multicast communication, the establishment, maintenance, and management of a group belong to the work of the application layer.

To sum up, for the multicast or broadcast service of the SL, the SL interface supports multiple sets of DRX/Discontinuous Transmission (DTX) configuration, but the problem of how to configure and how to ensure that the same DRX/DTX configuration can be used for data Transmission/reception between the transmitting terminal and the receiving terminal needs to be solved urgently, and no relevant solution exists at present.

Therefore, the present application provides a parameter configuration method applied to an SL interface, which determines configuration information of DRX or DTX used for instructing at least one receiving terminal to perform a multicast service or a broadcast service of the SL interface for direct communication, and sends the configuration information to the at least one receiving terminal, thereby improving efficiency, reliability, and node performance in a communication process between the sending terminal and the receiving terminal when the multicast service or the broadcast service is performed for the SL interface.

The following describes in detail a parameter configuration method, apparatus, and electronic device applied to a SL interface according to the present application with reference to the accompanying drawings.

Fig. 4 is a schematic diagram of a parameter configuration method applied to a SL interface according to the present application.

It should be noted that the main execution body of the parameter configuration method applied to the SL interface of the present application is a parameter configuration device applied to the SL interface of the direct communication. The parameter configuration method applied to the SL interface in the embodiment of the present application may be executed by the parameter configuration device applied to the SL interface in the embodiment of the present application, and the parameter configuration device applied to the SL interface in the embodiment of the present application may specifically be a hardware device, or software in a hardware device, or the like. The hardware devices are, for example, terminal devices, servers, and the like.

As shown in fig. 4, the parameter configuration method applied to the SL interface for direct communication proposed by the present application includes the following steps:

s401, determining configuration information of DRX or DTX for indicating at least one receiving terminal to carry out multicast service or broadcast service of a SL interface.

In the embodiment of the application, the configuration information may be determined based on the granularity or specific parameters.

S402, sending configuration information to at least one receiving terminal.

In the embodiment of the present application, the configuration information may be carried in the transmitted control signaling or may be carried in the transmitted data. That is, optionally, the configuration information may be sent to the receiving terminal through control signaling; alternatively, the configuration information may be transmitted to the receiving terminal through data.

As a possible implementation manner, a control signaling carrying configuration information for instructing the receiving terminal to perform DRX or DTX configuration is sent to the receiving terminal. Accordingly, the receiving terminal may receive the control signaling carrying the configuration information.

As another possible implementation, data carrying configuration information for instructing the receiving terminal to perform DRX or DTX configuration is sent to the receiving terminal. Accordingly, the receiving terminal may receive the data carrying the configuration information.

According to the parameter configuration method applied to the SL interface for direct communication, the configuration information of DRX or DTX used for instructing at least one receiving terminal to perform multicast service or broadcast service of the SL interface for direct communication can be determined, and the configuration information is sent to the at least one receiving terminal to instruct the receiving terminal to perform DRX or DTX configuration, so that the sending terminal and the receiving terminal can be ensured to use consistent DRX or DTX configuration to perform data sending or receiving, and the efficiency, reliability and node performance in the communication process between the sending terminal and the receiving terminal are improved when the multicast service or broadcast service of the SL interface is applied.

The following explains the parameter configuration method applied to the SL interface for direct communication proposed in the present application, with respect to the configuration information carried in the control signaling and data, respectively.

As a possible implementation manner for sending configuration information to a receiving terminal through a control signaling, as shown in fig. 5, the parameter configuration method applied to the SL interface for direct communication proposed in the present application includes the following steps:

s501, determining corresponding layer signaling or data load of the control signaling.

In the present application, the Control signaling may be any one of Non-Access Stratum (NAS) signaling, radio Resource Control (RRC), MAC CE, and direct communication side chain Control Information (SCI).

It should be noted that, in the present application, the specific type of the control signaling is not limited, and may be one of the NAS signaling, RRC signaling, MAC CE signaling, and SCI signaling described above, or may be another newly introduced SL interface control signaling.

In the embodiment of the present application, a corresponding layer signaling (protocol header) or a data payload (payload) of the control signaling may be determined.

S502, carrying the configuration information in a corresponding layer signaling or data load and sending the configuration information to a receiving terminal.

For NAS signaling using the SL interface, the configuration information may be carried in a protocol header or data payload corresponding to the control signaling;

for RRC signaling using the SL interface, the configuration information may be carried in a protocol header or data payload corresponding to the control signaling;

for the MAC CE signaling using the SL interface, the configuration information may be carried in a protocol header or data payload corresponding to the control signaling;

for SCI signaling using the SL interface, the configuration information may be carried in a protocol header or data payload corresponding to the control signaling.

It should be noted that, if the control signaling is an RRC signaling, optionally, the RRC signaling carrying DRX or DTX may be sent to the receiving terminal; optionally, RRC signaling carrying index information corresponding to DRX or DTX may be sent to the receiving terminal.

It should be noted that, if the control signaling is an SCI signaling, optionally, the SCI signaling carrying the index information corresponding to the DRX or DTX may be sent to the receiving terminal.

As a possible implementation manner for sending configuration information to a receiving terminal through data, as shown in fig. 6, the parameter configuration method applied to the SL interface for direct communication proposed in the present application includes the following steps:

s601, determining corresponding layer signaling or data load of the data.

It should be noted that, in the present application, within a UE (i.e. a sending terminal) that determines/initiates notification of a DRX configuration parameter index, the DRX configuration parameter that is finally determined for the current SL multicast/broadcast service is sent to a receiving terminal in a data encapsulation manner.

In this embodiment, the data may be user plane data of the SL interface, for example, the data may be a direct link Quality of Service indicator (PQI), or may also be a Layer 2Identity document (L2 ID).

And S602, carrying the configuration information in a corresponding layer signaling or data load and sending the configuration information to a receiving terminal.

For PQI, within a UE (i.e. a sending terminal) that determines/initiates notification of a DRX configuration parameter index, a DRX configuration parameter that is finally used by both sides (i.e. the sending terminal and a receiving terminal) is specified from a pre-configured DRX configuration parameter list with PQI as an index, the PQI information is transmitted to the receiving terminal in a data/data header, for example, in an Internet Protocol (IP) layer header, and the receiving terminal derives a corresponding PQI value through IP information, which is used for determining that the current multicast/broadcast service of the SL interface finally uses a target configuration in multiple sets of DRX configurations.

For the L2 ID, within the UE (i.e. the sending terminal) that determines/initiates notification of the DRX configuration parameter index, the L2 ID is used as an index to specify DRX configuration parameters that are finally used by both (i.e. the sending terminal and the receiving terminal) from a preconfigured DRX configuration parameter list, the L2 ID information is transmitted to the receiving terminal in a data/data header, for example, in a MAC subheader, and the receiving terminal determines, through the L2 ID information, a target configuration that is finally used in multiple sets of DRX configurations for the current SL interface multicast/broadcast service.

Furthermore, since the number of DRX/DTX configuration sets maintained by the terminal is not too large, the data may be grouped by a modulo processing or the like to ensure that the number of DRX/DTX parameter configuration sets usable by the terminal can meet the requirement.

As a possible implementation manner, as shown in fig. 7, the method specifically includes the following steps:

s701, determining the number of candidate data and DRX or DTX configuration information corresponding to the candidate data, wherein the candidate data is the address identifier of a direct link quality of service indicator PQI or Lay 2.

The quantity of the configuration information of DRX or DTX may be a recommended quantity pre-configured for the transmitting terminal and the receiving terminal. For example, it may be 2.

And S702, if the number reaches a preset threshold value, grouping the configuration information of DRX or DTX corresponding to the candidate data.

As a possible implementation manner, as shown in fig. 8, a specific process of grouping data in the above steps to obtain target data includes the following steps:

s801, obtaining the target number corresponding to the SL interface.

For example, the number of targets corresponding to the SL interface is acquired to be 4.

S802, according to the target quantity, conducting modular processing on the quantity of the configuration information of the DRX or DTX corresponding to the candidate data to obtain a grouping result.

In the embodiment of the present application, if the number reaches the preset threshold, the number of the configuration information of the DRX or DTX corresponding to the candidate data may be subjected to modulo processing to obtain a grouping result.

For example, the preset threshold may be set to the upper limit of the preconfigured number of the recommended DRX/DTX configurations, that is, 2 sets, and if the target number corresponding to the SL interface is obtained to be 4, the transmitting terminal has four services, PQI =1, PQI =2, PQI =3, and PQI = 4. In this case, if the number reaches the preset threshold, the four PQIs may be mapped into two DRX configuration parameter packets by a modulo method (PQI% N), that is, the number of DRX or DTX configuration information corresponding to the candidate data is modulo, so as to obtain a packet result.

It should be noted that, if the sending terminal transmits the configuration information to at least two receiving terminals by the above method, there is no requirement for the sending order of the configuration information.

According to the parameter configuration method applied to the SL interface for direct communication, the configuration information can be sent to the receiving terminal through the control signaling/data, so that the data processing efficiency is improved, and the efficiency and the reliability in the parameter configuration process applied to the SL interface for direct communication are further improved.

It should be noted that, in the present application, the granularity or specific parameters may be used as a basis when attempting to determine the configuration information of DRX or DTX for instructing at least one receiving terminal to perform multicast service or broadcast service of the SL interface for direct communication.

As a possible implementation manner, as shown in fig. 9, the parameter configuration method applied to the SL interface in the present application includes the following steps:

s901, determining configuration information of DRX or DTX for instructing at least one receiving terminal to perform multicast service or broadcast service of the SL interface for direct communication.

Optionally, a service type corresponding to a multicast service or a broadcast service of the SL interface may be determined, and the configuration information of DRX or DTX may be determined according to a priority of the service type. That is, it can be distinguished by the service type of the current SL multicast/broadcast service acquired by the higher layer.

Wherein, the priorities of different service types correspond to different configuration information. For example, if the service type is earthquake early warning, the corresponding configuration information may be a; and if the service type is the person searching notification, the corresponding configuration information can be B, and in this case, the earthquake early warning and the person searching notification have different corresponding priorities.

Optionally, a direct link quality of service indicator PQI corresponding to multicast service or broadcast service of the SL interface may be determined, and the configuration information of DRX or DTX may be determined according to an index value of the PQI. That is, it can be distinguished by the PQI index value of the current SL multicast/broadcast service acquired by the higher layer/AS layer (access layer).

Optionally, an address identifier (Destination ID) of Lay2 corresponding to multicast service or broadcast service of the SL interface may be determined, and the configuration information of DRX or DTX may be determined according to the address identifier of Lay 2.

When the Destination ID is used as a granularity basis for determining the configuration information, the configuration requiring DRX or DTX is also configured with the Destination ID as a granularity.

When the Quality of Service (QoS) parameter identifier of the SL interface such as PQI or PQI list is used as the basis for determining the granularity of the configuration information, the configuration requiring DRX or DTX is also configured with the granularity of PQI or PQI list.

S902, sending configuration information to at least one receiving terminal.

As a possible implementation, control signaling of the configuration information may be sent to the receiving terminal. Accordingly, the receiving terminal may receive control signaling of the configuration information.

As another possible implementation, the data of the configuration information may be sent to the receiving terminal. Accordingly, the receiving terminal may receive data of the configuration information.

Fig. 10 is a schematic diagram of a parameter configuration method applied to a SL interface according to the present application.

As shown in fig. 10, the parameter configuration method applied to the SL interface of the present application includes the following steps:

s1001, receiving configuration information sent by a sending terminal, wherein the configuration information is used for indicating the receiving terminal to perform discontinuous reception DRX or discontinuous transmission DTX of multicast service or broadcast service of a direct communication SL interface.

S1002, determining DRX or DTX according to the configuration information, and configuring.

In the embodiment of the present application, the configuration information may be carried in the transmitted control signaling or may be carried in the transmitted data. That is, optionally, the configuration information sent by the sending terminal through the control signaling may be received; alternatively, the configuration information transmitted by the transmitting terminal through data may be received.

As a possible implementation manner, a control signaling carrying configuration information for instructing the receiving terminal to perform DRX or DTX configuration may be sent to the receiving terminal. Accordingly, the receiving terminal may receive the control signaling carrying the configuration information.

As another possible implementation, data carrying configuration information for instructing the receiving terminal to perform configuration of DRX or DTX may be transmitted to the receiving terminal. Accordingly, the receiving terminal may receive the data carrying the configuration information.

According to the parameter configuration method applied to the SL interface for direct communication in the embodiment of the application, the configuration information sent by the sending terminal can be received, wherein the configuration information is used for instructing the receiving terminal to perform the configuration of Discontinuous Reception (DRX) or Discontinuous Transmission (DTX) so as to enable the receiving terminal to perform the configuration of DRX or DTX, thereby ensuring that the sending terminal and the receiving terminal can use the configuration of consistent DRX or DTX to transmit or receive data, and improving the efficiency, reliability and node performance in the communication process between the sending terminal and the receiving terminal when the multicast service or the broadcast service is performed on the SL interface.

It should be noted that, if the configuration information is carried in the data, the receiving terminal may determine DRX or DTX in different manners and perform configuration. The data may be user plane data of the SL interface, for example, PQI, or L2 ID.

The following explains the parameter configuration method applied to the SL interface for direct communication proposed in the present application with respect to data of PQI and L2 ID, respectively.

As a possible implementation manner for the data being PQI, as shown in fig. 11, the following steps are included:

s1101, receiving configuration information sent by a sending terminal, wherein the configuration information is used for indicating the receiving terminal to perform discontinuous reception DRX or discontinuous transmission DTX of multicast service or broadcast service of a direct communication SL interface.

As a possible implementation, data carrying configuration information for instructing the receiving terminal to perform DRX or DTX configuration may be transmitted to the receiving terminal by the transmitting terminal. Accordingly, the receiving terminal may receive the data carrying the configuration information.

And S1102, analyzing the PQI to obtain the value of the PQI.

And S1103, determining DRX or DTX according to the value, and configuring.

For example, if the PQI information is transmitted in the IP layer header, in this case, the receiving terminal may derive the corresponding PQI value through the IP information, so as to determine that the current multicast/broadcast service of the SL interface finally uses the target configuration of multiple DRX configurations.

As can be seen from the above, if the data is PQI, in this case, the configuration information received by the receiving terminal is an implicit indication information, and the DRX or DTX can be determined only after the received indication information is analyzed.

As a possible implementation manner, as shown in fig. 12, the method for determining that the data is L2 ID includes the following steps:

s1201, receiving configuration information sent by a sending terminal, wherein the configuration information is used for indicating the receiving terminal to perform Discontinuous Reception (DRX) or Discontinuous Transmission (DTX) of multicast service or broadcast service of a direct communication (SL) interface.

And S1202, determining DRX or DTX according to the L2 ID, and configuring.

For example, if the L2 ID information is transmitted in the MAC subheader, in this case, the receiving terminal may determine that the current multicast/broadcast service of the SL interface finally uses the target configuration of the multiple sets of DRX configurations through the L2 ID information and directly according to the L2 ID.

As can be seen from the above, if the data is L2 ID, the configuration information received by the receiving terminal is an explicit indication information, and the DRX or DTX can be directly determined from the L2 ID without performing processing such as analysis.

It should be noted that, in the present application, if the configuration information is carried by the data, before sending the data carrying the configuration information, the receiving terminal may perform direct communication interface monitoring according to all possible DRX/DTX configurations.

The parameter configuration method applied to the SL interface for direct communication proposed in the present application is explained below with respect to the overall process of communication between a sending terminal and a receiving terminal, in which configuration information is carried in control signaling and data, respectively.

As a possible implementation manner for carrying configuration information in a control signaling, as shown in fig. 13, the parameter configuration method applied to the SL interface for direct communication proposed by the present application includes the following steps:

s1301, the transmitting terminal determines configuration information for instructing the receiving terminal to perform DRX or DTX configuration.

S1302, the sending terminal sends the configuration information to the receiving terminal through the control signaling.

And S1303, the receiving terminal receives and configures the control signaling sent by the sending terminal.

As a possible implementation manner for carrying configuration information in data, as shown in fig. 14, the parameter configuration method applied to the SL interface for direct communication proposed by the present application includes the following steps:

s1401, a transmitting terminal determines configuration information for instructing a receiving terminal to perform DRX or DTX configuration.

S1402, the sending terminal sends the configuration information to the receiving terminal through the data.

S1403, the receiving terminal receives and configures the data of the configuration information transmitted by the transmitting terminal.
