Description

Information configuration method, device, equipment and computer readable storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information configuration method, apparatus, device, and computer-readable storage medium.
Background
For more efficient communication, direct communication between terminals is introduced. For convenience of description, a direct communication link between terminals is defined as a Sidelink link, and a corresponding wireless interface is referred to as a direct communication interface (also referred to as a Sidelink interface); a cellular communication link between the network side device and the terminal is referred to as a uulink link, and a corresponding interface thereof is referred to as a Uu interface. As shown in fig. 1, UE1 and UE2 communicate directly via a Sidelink link, and UE1 and UE2 communicate with a network device via a uulink link.
For a direct communication interface, any power saving mechanism is not supported at present, so that the terminal consumes power quickly, and the user experience is not good. Therefore, a DRX (Discontinuous Reception) configuration of a direct communication interface needs to be introduced. According to the related mechanism of the current direct communication interface, there may exist a plurality of PC5-S connections between two direct communication terminals. If the DRX of the direct communication interface is configured based on the PC5-S connections, the DRX configurations of different PC5-S connections may be completely different and thus, true power saving of the terminal may not be achieved.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Referring to fig. 2, fig. 2 is a flowchart of an information configuration method provided in an embodiment of the present invention, and is applied to a direct communication terminal, as shown in fig. 2, including the following steps:
step 201, determining a DRX configuration of a direct communication interface corresponding to a direct communication interface specific target based on the direct communication interface specific target; wherein the specific target comprises a direct communication terminal or a direct communication interface transmission type.
Specifically, the type of the direct communication interface transmission may be a unicast, multicast, or broadcast of the direct communication interface, or the type of the direct communication interface transmission may be a unicast or multicast of the direct communication interface.
In the embodiment of the present invention, the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface may be configured in at least the following ways:
and the first mode is that the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface is determined according to protocol agreement or pre-configuration information.
That is, in this manner, the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface is agreed by the protocol or written in the preconfiguration information.
And secondly, determining the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface according to the connection state information of the direct communication terminal.
The connection state information of the direct communication terminal includes that the Uu interface is in an RRC CONNECTED state (CONNECTED), that the Uu interface is in an RRC IDLE state (IDLE) or an RRC INACTIVE state (INACTIVE), that the Uu interface is in an off-network state, and the like.
Based on different connection states of the direct communication terminal on the Uu interface, the direct communication terminal determines the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface in different modes.
2.1 the direct communication terminal is in RRC connected state at the Uu interface.
In this case, the DRX configuration of the direct communication interface to which the direct communication interface specific target corresponds may be determined as follows.
(1) And the direct communication terminal receives the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface, which is sent by the network side equipment through the Uu interface special signaling, namely the direct communication interface adopts independent DRX configuration.
Specifically, in this case, the direct communication terminal receives configuration information sent by the network side device through Uu interface dedicated signaling, where the configuration information at least includes first indication information and DRX configuration corresponding to the direct communication specific target, or the configuration information at least includes the first indication information, the direct communication interface specific target indication information, and DRX configuration of a direct communication interface corresponding to the direct communication interface specific target.
The first indication information is used to indicate an interface type targeted by the configuration information, and may be 1-bit interface identification information. The direct communication interface specific target indication information may be identification information of the direct communication terminal, and specifically, the identification information of the direct communication terminal may be, but is not limited to, a C-RNTI (Cell Radio Network Temporary Identifier).
Further, if the DRX configurations corresponding to different transmission types of the direct communication interface are different, the network side device needs to indicate the transmission type of the direct communication interface corresponding to the network side device when indicating the DRX configuration of the direct communication interface.
(2) And the direct communication terminal receives the DRX configuration of the Uu interface sent by the network side equipment, and takes the DRX configuration of the Uu interface as the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface. That is, the direct communication interface multiplexes DRX configurations of the Uu interface.
Optionally, in this case, the network side device may further carry second indication information while configuring the DRX configuration of the Uu interface, where the second indication information is used to indicate whether the DRX configuration of the Uu interface is applicable to the direct communication interface, and the second indication information may be 1bit. In this way the same DRX configuration is used for different transmission types of the direct communication interface.
2.2 the direct communication terminal is in an RRC idle state or an RRC inactive state at the Uu interface.
In this case, the direct communication terminal receives the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target, which is transmitted by the network side device through the SIB.
Specifically, the direct communication terminal may receive configuration information sent by the network side device through the SIB, where the configuration information includes DRX configuration of the direct communication interface corresponding to the target specific to the direct communication interface.
Further, if the DRX configurations corresponding to different transmission types of the direct communication interface are different, the network side device needs to indicate the transmission type of the direct communication interface corresponding to the network side device when indicating the DRX configuration of the direct communication interface.
2.3 direct communication terminal is in off-network state at Uu interface.
In this case, the direct communication terminal configures the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target through the preconfiguration information. In addition, if DRX configurations corresponding to different transmission types of the direct communication interface are different, the preconfiguration information further needs to indicate the transmission type of the direct communication interface corresponding to the DRX configuration.
And thirdly, determining the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface according to the realization of the direct communication terminal.
That is, in this manner, the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target is determined according to the algorithm of the direct communication terminal itself. The specific algorithm is not limited in the embodiment of the present invention. If the DRX configuration of the direct communication interface is determined based on the direct communication terminal, only one set of DRX configuration needs to be determined by one direct communication terminal; if the DRX configuration of the direct communication interface is determined based on different transmission types of the direct communication interface, one direct communication terminal needs to determine DRX configurations corresponding to the transmission types respectively for the different transmission types of the direct communication interface.
In the embodiment of the invention, the discontinuous reception DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface is determined based on the specific target of the direct communication interface, so that a plurality of DRX configurations corresponding to the same transmission type under the connection of PC5-S or the connection of PC5-S between two terminals can be aligned, thereby being beneficial to realizing the electricity saving of the direct communication terminal.
On the basis of the foregoing embodiment, in order to facilitate the direct interface communication, the direct communication terminal may further send, to a communication peer of the direct communication terminal, the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target.
Specifically, the transmission mode of the direct communication terminal is different according to different transmission types. The transmission type of the direct communication interface comprises unicast of the direct communication interface, multicast of the direct communication interface and broadcast of the direct communication interface.
(1) And under the condition that the transmission type of the direct communication interface is unicast, the direct communication terminal sends the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to a communication opposite terminal of the direct communication terminal through PC5-RRC signaling.
In this case, in order to ensure that the same DRX configuration is used for a plurality of PC5-S connections between two direct communication terminals, the direct communication terminals may configure the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target based on the PC5-S connections between the direct communication terminals. But it is required that different PC5-S connections between two direct communication terminals must be able to use the same direct communication interface DRX configuration, i.e. different PC5-S connections between two direct communication terminals both use the above terminal based determined DRX configuration or both use the above terminal based direct communication interface unicast determined DRX configuration.
Or, in order to ensure that a plurality of PC5-S connections between two direct communication terminals use the same DRX configuration, the direct communication terminal can also configure the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface based on the UE-to-identification information or the UE AS connection identification information of the direct communication interface. The UE can use the identification information to identify a combination formed by two direct communication terminals which carry out communication interaction in the direct communication interface. At this time, the direct communication terminal may send the UE-to-UE identity information or the UE AS connection identity information to a correspondent node of the direct communication terminal. Specifically, the direct communication terminal may interact the UE-to-identifier information or the UE AS connection identifier information when establishing the PC5-S connection. At this time, the UE pair identity information or UE AS connection identity information is carried in a signaling for establishing PC5-S connection. Or the direct communication terminal can also interact the UE pair identification information or the UE AS connection identification information after establishing PC5-S connection. At this time, the UE pair identification information or the UE AS connection identification information is carried in a PC5-RRC signaling.
(2) And under the condition that the transmission type of the direct communication interface is direct communication interface multicast, sending the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to a communication opposite end of the direct communication terminal in a multicast mode.
(3) And under the condition that the transmission type of the direct communication interface is the direct communication interface broadcast, sending the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to a communication opposite end of the direct communication terminal in a broadcast mode.
For the multicast and broadcast of the direct communication interface, in order to ensure that different multicast or broadcast use the same DRX configuration, the direct communication terminal may multicast or broadcast as follows: and multicasting or broadcasting the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface based on the combination of the source address and the destination address of the direct communication interface. If the specific target is a direct communication terminal, the direct communication terminal needs to multicast or broadcast the completely same DRX configuration information of the direct communication interface when multicasting or broadcasting aiming at different source/destination address combinations; if the specific target is a direct communication interface transmission type, the direct communication interface aims at using different source/destination address combinations, and if the direct communication interface corresponds to the same transmission type, the same DRX configuration information is used.
In this embodiment of the present invention, sending, to a correspondent node of direct communication of the direct communication terminal, a DRX configuration of a direct communication interface corresponding to a specific target of the direct communication interface in a manner of repeated transmission includes any one of the following manners:
(1) And sending the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to a communication opposite end of the direct communication terminal by adopting a repeated transmission mechanism, namely repeatedly transmitting for N times on continuous time units. N is an integer greater than 1.
(2) And repeatedly sending the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to a communication opposite end of the direct communication terminal according to a preset period. The preset period may be preconfigured or agreed by a protocol, and the preset period may also be a DRX period.
(3) And repeatedly sending the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to a communication opposite end of the direct communication terminal on specific time domain resources or frequency domain resources. The specific time domain resource or frequency domain resource may be a protocol agreement, or may be preconfigured, or may be notified to its direct communication peer by the direct communication terminal.
In this embodiment of the present invention, the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface at least includes the following information:
starting point of DRX;
the cycle length of the DRX;
the length of the DRX active period or the length of the inactive period.
The DRX configuration of the direct communication interface corresponding to the direct communication interface specific target further comprises a length of a target timer, the target timer comprising one or more of the following timers:
a HARQ RTT timer;
a HARQ retransmission timer;
the DRX inactivity timer.
Referring to fig. 3, fig. 3 is a flowchart of an information configuration method provided by an embodiment of the present invention, and is applied to a network side device, as shown in fig. 3, including the following steps:
step 301, determining the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface.
Wherein the specific target comprises a direct communication terminal or a direct communication interface transmission type. In the embodiment of the present invention, a manner of determining, by the network side device, the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface is not limited, and may be determined according to a protocol convention or a preconfigured manner, for example. The transmission type of the direct communication interface comprises unicast, multicast and broadcast of the direct communication interface, or the transmission type of the direct communication interface comprises unicast and multicast of the direct communication interface.
Step 302, sending the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target to the direct communication terminal.
In the embodiment of the invention, the network side equipment has different sending modes according to the connection state of the direct communication terminal on the Uu interface.
And under the condition that the direct communication terminal is in an RRC (radio resource control) connection state at the Uu interface, the network side equipment sends DRX (discontinuous reception) configuration of a direct communication interface corresponding to the specific target of the direct communication interface to the direct communication terminal through Uu interface dedicated signaling. Specifically, the network side device sends configuration information to the direct communication terminal through a Uu interface dedicated signaling, where the configuration information at least includes first indication information and DRX configuration of a direct communication interface corresponding to the direct communication interface specific target, or the configuration information at least includes the first indication information, the direct communication interface specific target indication information, and DRX configuration of a direct communication interface corresponding to the direct communication interface specific target; wherein the first indication information is used for indicating the interface type for which the configuration information is directed. The meaning and implementation form of the first indication information and the direct communication interface specific target indication information may refer to the description of the foregoing embodiments.
Or, when the direct communication terminal is in an RRC connected state at the Uu interface, the network side device sends the DRX configuration of the Uu interface to the direct communication terminal, so that the direct communication terminal uses the DRX configuration of the Uu interface as the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface. At this time, the network side device may further send second indication information to the direct communication terminal, where the second indication information is used to indicate whether the DRX configuration of the Uu interface is applicable to the direct communication interface.
And under the condition that the Uu interface of the direct communication terminal is in an RRC idle state or an RRC inactive state, the network side equipment sends the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface to the direct communication terminal through an SIB. If the DRX configurations corresponding to different transmission types of the direct communication interface are different, the network side device further needs to indicate the transmission type of the direct communication interface corresponding to the network side device when indicating the DRX configuration of the direct communication interface.
In the embodiment of the invention, the discontinuous reception DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface is determined based on the specific target of the direct communication interface, so that a plurality of DRX configurations corresponding to the same transmission type under the connection of PC5-S or the connection of PC5-S between two terminals can be aligned, thereby being beneficial to realizing the electricity saving of the direct communication terminal.
Referring to fig. 4, fig. 4 is a flowchart of an information configuration method provided in an embodiment of the present invention, and is applied to a direct communication terminal, as shown in fig. 4, including the following steps:
step 401, receiving a DRX configuration of a direct communication interface corresponding to a direct communication interface specific target sent by a direct communication peer.
The DRX configuration of the direct communication interface corresponding to the direct communication interface specific target is determined by the direct communication opposite end based on the direct communication interface specific target, and the specific target comprises a direct communication terminal or a direct communication interface transmission type. Specifically, the type of the direct communication interface transmission may be a unicast, multicast, or broadcast of the direct communication interface, or the type of the direct communication interface transmission may be a unicast or multicast of the direct communication interface.
Specifically, in this step, according to the transmission type of the direct communication interface, the direct communication terminal has the following receiving mode:
under the condition that the transmission type of the direct communication interface is unicast of the direct communication interface, receiving DRX configuration of the direct communication interface corresponding to a specific target of the direct communication interface, which is sent by the opposite direct communication terminal through PC5-RRC signaling;
receiving DRX configuration of a direct communication interface corresponding to a specific target of the direct communication interface, which is sent by the direct communication opposite end in a multicast mode, under the condition that the transmission type of the direct communication interface is direct communication interface multicast;
and under the condition that the transmission type of the direct communication interface is the direct communication interface broadcast, receiving the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface, which is sent by the direct communication opposite terminal in a broadcast mode.
Wherein, in case that the transmission type of the direct communication interface is direct communication interface unicast, the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target is configured based on the PC5-S connection between direct communication terminals, or the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target is configured based on UE pair identity information or UE AS connection identity information of the direct communication interface. At this time, the direct communication terminal may further receive the UE pair identifier information or the UE AS connection identifier information sent by the direct communication peer. Specifically, the direct communication terminal may receive the UE pair identifier information or the UE AS connection identifier information sent by the direct communication peer through a signaling for establishing a PC5-S connection; or receiving the UE pair identification information or the UE AS connection identification information sent by the direct communication opposite end through PC5-RRC signaling.
In the embodiment of the present invention, in order to implement reliable reception of the DRX configuration, when receiving the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface sent by the direct communication peer, the direct communication terminal includes any one of the following manners:
(1) And adopting a repeated receiving mechanism to receive the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface, which is sent by the direct communication opposite terminal, namely repeatedly receiving for N times on continuous time units. N is an integer greater than 1.
(2) And repeatedly receiving the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface, which is sent by the direct communication opposite terminal, according to a preset cycle. The preset period may be pre-configured or agreed by a protocol, and the preset period may also be a DRX period.
(3) And repeatedly receiving the DRX configuration of the direct communication interface corresponding to the direct communication interface specific target sent by the direct communication opposite end on a specific time domain resource or frequency domain resource. The specific time domain resource or frequency domain resource may be protocol-agreed, or pre-configured, or notified to its direct communication peer by the direct communication terminal.
In this embodiment of the present invention, the DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface at least includes the following information:
starting point of DRX;
a cycle length of DRX;
the length of the DRX active period or the length of the inactive period.
The DRX configuration of the direct communication interface to which the direct communication interface specific target corresponds further comprises a length of a target timer comprising one or more of the following timers:
a HARQ RTT timer;
a HARQ retransmission timer;
the DRX inactivity timer.
In the embodiment of the invention, the discontinuous reception DRX configuration of the direct communication interface corresponding to the specific target of the direct communication interface is determined based on the specific target of the direct communication interface, so that a plurality of DRX configurations corresponding to the same transmission type under the connection of PC5-S or the connection of PC5-S between two terminals can be aligned, thereby being beneficial to realizing the electricity saving of the direct communication terminal.
At present, two same UEs of a direct communication interface are only connected with a PC5-S, and are not connected with an AS layer. For better power saving, it is necessary to consider how to align as much as possible the DRX active periods of the Uu interface and the multiple different PC5-S connections between the two same UEs.
To solve the above problem, in the embodiment of the present invention, the DRX configuration of the direct communication interface is configured based on the direct communication terminal or based on different transmission types of the direct communication interface. Wherein the transmission type includes unicast, multicast and broadcast of the direct communication interface.
Fig. 5 is a flowchart of an information configuration method according to an embodiment of the present invention. In the embodiment of the invention, the DRX configuration agreed by a protocol is adopted for the direct communication interface. That is, in this manner, the DRX configuration adopted by the direct communication interface is agreed by a protocol, and a specific agreed manner may be agreed based on the direct communication interface or agreed based on different transmission types of the direct communication interface respectively. In this way, no interaction is required between the direct communication transceiving terminals. As shown in fig. 5, the method comprises the steps of:
step 501: the direct communication terminal acquires the DRX configuration.
For the direct communication terminal UE1 or UE2, the DRX configuration can be obtained, as shown in steps 501a and 501 b. Wherein, the step 501a and the step 501b have no definite sequence. That is, the DRX configuration adopted by the direct communication interface is agreed by a protocol, and a specific agreed manner may be agreed based on the direct communication interface or respectively agreed based on different transmission types of the direct communication interface. In this way, no interaction is required between the direct communication transceiving terminals.
In this embodiment of the present invention, the content of the DRX configuration at least includes the following information:
a starting point of DRX;
DRX cycle length;
DRX active period length or inactive period length (which may be embodied as a specific time length or timer length).
Optionally, the DRX related timer length is also maintained, for example:
a HARQ RTT timer;
a HARQ retransmission timer;
the DRX inactivity timer.
Step 502: and data transmission is carried out between the direct communication terminals according to the DRX configuration of a direct communication interface.
That is, according to the DRX configuration, during DRX activation, a direct communication terminal performs data transmission on a direct communication interface, and a communication peer of the direct communication terminal performs data reception on the direct communication interface. During the DRX silent period, the direct communication terminal does not transmit data on the direct communication interface, and a communication opposite end of the direct communication terminal does not receive data on the direct communication interface.
In the embodiment of the invention, different DRX configuration modes can be adopted based on different states of the direct communication terminal. Wherein, the state of the direct communication terminal may include: RRC connected state of Uu port, RRC idle state or non-activated state of Uu port, off-line state of Uu port, etc.
Fig. 6 is a flowchart of an information configuration method according to an embodiment of the present invention. In fig. 6, the direct communication terminal UE1 is taken as an example of a direct communication interface DRX configuration management node, and the direct communication terminal UE1 is in an RRC connected state at the Uu port. As shown in fig. 6, the method includes the steps of:
step 601: the network side device of the direct communication terminal UE1 notifies the direct communication terminal UE1 of the DRX configuration of the direct communication interface.
In a specific application, the method can be realized by at least two ways:
in the first mode, the direct communication interface adopts independent DRX configuration.
The network side device configures configuration information of the direct communication interface through Uu interface dedicated signaling (RRC signaling, MAC (Medium Access Control) signaling, or physical layer signaling), where the configuration information at least includes:
(1) 1bit interface identification information for indicating that the configuration information is directed to a direct communication interface;
(2) DRX configuration of the direct communication interface.
If the DRX configurations corresponding to different transmission types of the direct communication interface are different, the network side device needs to indicate the transmission type of the direct communication interface corresponding to the network side device when indicating the DRX configuration of the direct communication interface.
And in the second mode, the direct communication interface multiplexes DRX configuration of the Uu interface.
Optionally, the indication information is carried while the network side device configures the DRX configuration of the Uu interface to indicate whether the DRX configuration of the Uu interface is applicable to the direct communication interface. Wherein, the indication information may be 1bit. In this way, the direct communication interface uses the same DRX configuration for different transmission types.
In this embodiment of the present invention, the content of the DRX configuration at least includes the following information:
starting point of DRX;
DRX cycle length;
DRX active period length or inactive period length (which may be embodied as a specific time length or timer length).
Optionally, the length of the DRX related timer is also carried, for example:
a HARQ RTT timer;
a HARQ retransmission timer;
the DRX inactivity timer.
Step 602: the direct communication terminal UE1 notifies its communication counterpart of the DRX configuration of the direct communication interface.
In the embodiment of the present invention, a communication peer is taken as a direct communication terminal UE2 as an example.
Specifically, for the unicast of the direct communication interface, the direct communication terminals interact with the DRX configuration of the direct communication interface through PC5-RRC signaling.
For the multicast of the direct communication interface, the direct communication terminal (direct communication terminal UE 1) may notify the DRX configuration of the direct communication interface to its direct communication peer (e.g., direct communication terminal UE 2) in a multicast manner.
For the direct communication interface broadcast, the direct communication terminal (direct communication terminal UE 1) may notify its direct communication counterpart (e.g. direct communication terminal UE 2) of the DRX configuration of the direct communication interface in a broadcast manner.
For the unicast of the direct communication interface, in order to ensure that a plurality of PC5-S connections between two terminals use the same DRX configuration, there are two specific configurations:
mode 1: the direct communication interface DRX configuration is configured based on the PC5-S connection, but it is required that different PC5-S connections between two direct communication terminals must be able to use the same direct communication interface DRX configuration, i.e. different PC5-S connections between two direct communication terminals both use the terminal-based determined DRX configuration or both use the terminal-based direct communication interface unicast determined DRX configuration.
Mode 2: the configuration of the direct communication interface DRX is based on that the UE with the only direct communication interface performs the configuration of the direct communication interface DRX on the identification information or the only UE AS connection identification information.
AS for the above mode 2, the direct communication terminals need to interact with the unique UE pair identifier or UE AS connection identifier, and the specific interaction mode may be:
mode 2.1: and the direct communication terminals are interacted when establishing PC5-S connection, and the UE needs to carry identification information or UE AS connection identification in a PC5-S signaling.
Mode 2.2: after PC5-S connection is established between the direct communication terminals, the identification information of the UE pair or the UE AS connection identification is interacted through PC5-RRC signaling.
For the multicast and broadcast of the direct communication interface, in order to ensure that different multicast or broadcast use the same DRX configuration, the direct communication terminal may multicast or broadcast as follows:
the direct communication interface DRX configuration is multicast or broadcast based on the combination of a source address and a destination address of the direct communication interface, if a specific target is a direct communication terminal, the direct communication terminal needs to multicast or broadcast the completely same direct communication interface DRX configuration information when multicast or broadcast is carried out on different source/destination address combinations; if the specific target is a direct communication interface transmission type, the direct communication interface aims at using different source/destination address combinations, and if the direct communication interface corresponds to the same transmission type, the same DRX configuration information is used.
In addition, for multicast and broadcast, the direct communication interface DRX configuration management node (direct communication terminal UE 1) needs to use a retransmission scheme when transmitting the DRX configuration. The rule of the specific repeated transmission may be one or a combination of the following:
(1) The DRX configuration adopts a repeated transmission mechanism for each transmission, namely the transmission is repeated for N times on continuous time units; n is an integer greater than 1.
(2) The DRX configuration carries out repeated transmission according to a certain period T; the period T may be preconfigured or agreed by a protocol, or the period T may also take the period of DRX.
(3) The DRX configuration is repeatedly transmitted on a specific time or frequency domain resource. Wherein, the specific time domain or frequency domain resource may be protocol-agreed or pre-configured or notified to its direct communication counterpart by the direct communication terminal.
Step 603: and data transmission is carried out between the direct communication terminals according to the DRX configuration of a direct communication interface.
That is, according to the DRX configuration, during DRX activation, a direct communication terminal performs data transmission on a direct communication interface, and a communication peer of the direct communication terminal performs data reception on the direct communication interface. During the DRX silent period, the direct communication terminal does not transmit data on the direct communication interface, and a communication opposite end of the direct communication terminal does not receive data on the direct communication interface.
Fig. 7 is a flowchart of an information configuration method according to an embodiment of the present invention. In fig. 7, the direct communication terminal UE1 is taken as an example of a direct communication interface DRX configuration management node, and the direct communication terminal UE1 is in an IDLE state or an INACTIVE state at the Uu port. As shown in fig. 7, the method includes the steps of:
step 701: the network side device of the direct communication terminal UE1 notifies the direct communication terminal UE1 of the DRX configuration of the direct communication interface.
The direct communication terminal UE1 is in an idle state or an inactive state at the Uu port, and the specific configuration mode may be to configure the DRX configuration of the direct communication interface through an SIB. The configuration information configured by the SIB includes at least: DRX configuration of the direct communication interface. If the DRX configurations corresponding to different transmission types of the direct communication interface are different, the network side device further needs to indicate the corresponding direct communication interface type when indicating the DRX configuration of the direct communication interface.
In the embodiment of the present invention, the content of the DRX configuration at least includes the following information:
a starting point of DRX;
DRX cycle length;
DRX active period length or inactive period length (which may be embodied as a specific time length or timer length).
Optionally, the length of the DRX related timer is also carried, for example:

Step 702: the direct communication terminal UE1 notifies its correspondent node of the DRX configuration of the direct communication interface.
In the embodiment of the present invention, a communication peer is taken as the direct communication terminal UE2 as an example.
Specifically, for the unicast of the direct communication interface, the DRX configuration of the direct communication interface is interacted between the direct communication terminals through PC5-RRC signaling.
For the multicast of the direct communication interface, the direct communication terminal (the direct communication terminal UE 1) may notify the DRX configuration of the direct communication interface to its direct communication peer (e.g., the direct communication terminal UE 2) through a multicast manner.
For the direct communication interface broadcast, the direct communication terminal (direct communication terminal UE 1) may notify its direct communication counterpart (e.g. direct communication terminal UE 2) of the DRX configuration of the direct communication interface in a broadcast manner.
For the unicast of the direct communication interface, in order to ensure that a plurality of PC5-S connections between two terminals use the same DRX configuration, there are two specific configurations:
mode 1: the direct communication interface DRX configuration is configured based on the PC5-S connection, but it is required that different PC5-S connections between two direct communication terminals must be able to use the same direct communication interface DRX configuration, i.e. different PC5-S connections between two direct communication terminals both use the terminal-based determined DRX configuration or both use the terminal-based direct communication interface unicast determined DRX configuration.
Mode 2: and the direct communication interface DRX configuration is carried out on the basis of unique UE pair identification information or unique UE AS connection identification information of the direct communication interface.
For the above mode 2, a unique UE pair identifier or UE AS connection identifier needs to be interacted between the direct communication terminals, and the specific interaction mode may be:
mode 2.1: and the direct communication terminals are interacted when establishing PC5-S connection, and the UE needs to carry identification information or UE AS connection identification in a PC5-S signaling.
Mode 2.2: after PC5-S connection is established between the direct communication terminals, the identity information of the UE or the connection identity of the UE AS is interacted through PC5-RRC signaling.
For the multicast and broadcast of the direct communication interface, in order to ensure that different multicast or broadcast use the same DRX configuration, the direct communication terminal may multicast or broadcast as follows:
the direct communication interface DRX configuration is multicast or broadcast based on the combination of a source address and a destination address of the direct communication interface, if a specific target is a direct communication terminal, the direct communication terminal needs to multicast or broadcast the completely same direct communication interface DRX configuration information when multicast or broadcast is carried out on different source/destination address combinations; if the specific target is a direct communication interface transmission type, the direct communication interface aims at using different source/destination address combinations, and if the direct communication interface corresponds to the same transmission type, the same DRX configuration information is used.
In addition, for multicast and broadcast, the direct communication interface DRX configuration management node (direct communication terminal UE 1) needs to use a retransmission scheme when transmitting the DRX configuration. The rule of the specific repeated transmission may be one or a combination of the following:
(1) The DRX configuration adopts a repeated transmission mechanism for each transmission, namely the transmission is repeated for N times on continuous time units; n is an integer greater than 1.
(2) The DRX configuration carries out repeated transmission according to a certain period T; the period T may be preconfigured or agreed by a protocol, or the period T may also take the period of DRX.
(3) The DRX configuration is repeatedly transmitted on a specific time or frequency domain resource. Wherein, the specific time domain or frequency domain resource may be protocol convention or preconfigured or notified to its direct communication counterpart by the direct communication terminal.
Step 703: and data transmission is carried out between the direct communication terminals according to the DRX configuration of a direct communication interface.
That is, according to the DRX configuration, during DRX activation, a direct communication terminal performs data transmission on a direct communication interface, and a communication peer of the direct communication terminal performs data reception on the direct communication interface. During the DRX silent period, the direct communication terminal does not transmit data on the direct communication interface, and a communication opposite end of the direct communication terminal does not receive data on the direct communication interface.

In fig. 9, the direct communication terminal UE1 is taken as an example of a direct communication interface DRX configuration management node, and the direct communication terminal UE1 determines the direct communication interface DRX configuration based on a direct communication terminal implementation algorithm.

If the DRX configuration of the direct communication interface is determined based on the direct communication terminal, only one set of DRX configuration needs to be determined by one direct communication terminal; if the DRX configuration of the direct communication interface is determined based on different transmission types of the direct communication interface, one direct communication terminal needs to determine DRX configurations corresponding to the transmission types respectively for the different transmission types of the direct communication interface.

Step 902: the direct communication terminal UE1 notifies its communication counterpart of the DRX configuration of the direct communication interface.
In the embodiment of the present invention, a communication peer is taken as the direct communication terminal UE2 as an example.
Specifically, for the unicast of the direct communication interface, the direct communication terminals interact with the DRX configuration of the direct communication interface through PC5-RRC signaling.
For the multicast of the direct communication interface, the direct communication terminal (direct communication terminal UE 1) may notify the DRX configuration of the direct communication interface to its direct communication peer (e.g., direct communication terminal UE 2) in a multicast manner.
For the direct communication interface broadcast, the direct communication terminal (direct communication terminal UE 1) may notify its direct communication peer (e.g. direct communication terminal UE 2) of the DRX configuration of the direct communication interface in a broadcast manner.
For the unicast of the direct communication interface, in order to ensure that a plurality of PC5-S connections between two terminals use the same DRX configuration, there are two specific configurations:
mode 1: the direct communication interface DRX configuration is configured based on the PC5-S connection, but it is required that different PC5-S connections between two direct communication terminals must be able to use the same direct communication interface DRX configuration, i.e. different PC5-S connections between two direct communication terminals each use the terminal-based determined DRX configuration described above or each use the terminal-based direct communication interface unicast determined DRX configuration described above.
Mode 2: the configuration of the direct communication interface DRX is based on that the UE with the only direct communication interface performs the configuration of the direct communication interface DRX on the identification information or the only UE AS connection identification information.
AS for the above mode 2, the direct communication terminals need to interact with the unique UE pair identifier or UE AS connection identifier, and the specific interaction mode may be:
mode 2.1: and the direct communication terminals are interacted when establishing PC5-S connection, and the UE needs to carry identification information or UE AS connection identification in a PC5-S signaling.
Mode 2.2: after PC5-S connection is established between the direct communication terminals, the identification information of the UE pair or the UE AS connection identification is interacted through PC5-RRC signaling.
For the multicast and broadcast of the direct communication interface, in order to ensure that different multicast or broadcast use the same DRX configuration, the direct communication terminal may multicast or broadcast as follows:
the direct communication interface DRX configuration is multicast or broadcast based on the combination of a source address and a destination address of the direct communication interface, if a specific target is a direct communication terminal, the direct communication terminal needs to multicast or broadcast the completely same direct communication interface DRX configuration information when multicast or broadcast is carried out on different source/destination address combinations; if the specific target is a direct communication interface transmission type, the direct communication interface aims at using different source/destination address combinations, and if the direct communication interface corresponds to the same transmission type, the same DRX configuration information is used.
In addition, for multicast and broadcast, the direct communication interface DRX configuration management node (direct communication terminal UE 1) needs to use a retransmission scheme when transmitting the DRX configuration. The rule of the specific repeated transmission may be one or a combination of the following:
(1) The DRX configuration adopts a repeated transmission mechanism for each transmission, namely the transmission is repeated for N times on continuous time units; n is an integer greater than 1.
(2) The DRX configuration carries out repeated transmission according to a certain period T; the value of the period T may be preconfigured or agreed by a protocol, or the period T may also take the period of DRX.
(3) The DRX configuration is repeatedly transmitted on a specific time or frequency domain resource. Wherein, the specific time domain or frequency domain resource may be protocol convention or preconfigured or notified to its direct communication counterpart by the direct communication terminal.
Step 903: and data transmission is carried out between the direct communication terminals according to the DRX configuration of a direct communication interface.
That is, according to the DRX configuration, during DRX activation, a direct communication terminal performs data transmission on a direct communication interface, and a communication peer of the direct communication terminal performs data reception on the direct communication interface. During the DRX silent period, the direct communication terminal does not transmit data on the direct communication interface, and a communication opposite end of the direct communication terminal does not receive data on the direct communication interface.
