Description

Method and equipment for determining logical channel group identification

The application is a divisional application of Chinese patent application with application number 201810892147.4, application date 2018, 8 and 7, and the application name of a method and a device for determining logical channel group identification, which is incorporated by reference in its entirety.

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method and apparatus for determining a logical channel group identifier.

Background

With the continuous development of wireless communication technology, in order to better meet the demands of users and improve the efficiency of information interaction between devices, 3GPP (the 3rd Generation Partnership Project, third generation partnership project) has introduced direct communication between devices.

The devices for direct communication can be all on-line devices, all off-line devices, part of on-line devices and part of off-line devices. The devices involved in direct communication are located within the coverage of the 3GPP direct communication carrier, so-called on-network, and the devices involved in direct communication are not located within the 3GPP direct communication carrier, so-called off-network.

Typical direct communication scenarios include the following three:

devices that communicate directly one-to-one;

a device may send the same data, i.e., group communications, to all devices in a communication group at a time;

one device may send the same data, i.e., broadcast communications, to all nearby devices at a time.

Direct communication supports two ways of direct communication transmission resource allocation:

resource allocation mode of network scheduling: the network allocates resources for the terminal according to a BSR (Buffer Status Report ) reported by the terminal by a direct communication link buffer;

The terminal autonomously selects a resource allocation mode of the resource: i.e. the terminal selects resources from a pre-configured or network broadcast transmission resource pool to transmit the direct communication link.

For the resource allocation mode of direct communication network scheduling, the sidelink BSR is reported based on the Destination ID (Destination address number corresponding to direct communication data) and the LCG ID (Logical Channel Group Identity, logical channel group identifier). Taking even number as an example, the specific format is shown in fig. 1.

In a conventional LTE system, when a logical channel is established, the network configures QoS (Quality of Service ) parameters for each logical channel, which are known to the base station, so that the base station can perform QoS-based scheduling.

For direct communication, the QoS parameters given by the upper layer include PPPP (ProSe Priority Per Packet, priority of each direct communication packet) and PPPR (ProSe Realibility Per Packet, reliability of each direct communication packet).

At present, the mapping relationship between the PPPP and the LCG ID and the mapping relationship between the PPPR and the LCG ID are configured independently, so that the LCG ID determined according to PPPP and the LCG ID determined according to PPPR may be different for a certain direct communication LC (Logical Channel), that is, there is a non-unique mapping between the LC and the LCG ID, so that the mapping relationship between the Logical Channel and the Logical Channel group of the direct communication interface is not unique.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The application scenario described in the embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application, and as a person of ordinary skill in the art can know that the technical solution provided by the embodiment of the present application is applicable to similar technical problems as the new application scenario appears.

For resource allocation of network scheduling in direct communication, a sidelink BSR reported by a terminal is reported based on a destination address number and a logical channel group number corresponding to data, and in order to ensure scheduling accuracy, the corresponding relationship between a logical channel of a direct communication interface and a logical channel group identifier needs to be unique. When LC and LCG ID are in one-to-one correspondence, the correspondence between the logic channels of the direct communication interface and the logic channel group is unique, namely, the correspondence between the QoS information of the direct communication interface and the logic channel group identification is unique.

The network side equipment establishes the corresponding relation between the QoS information of the direct communication interface and the logical channel group identifier, and the terminal determines the logical channel group identifier corresponding to the QoS information of the current direct communication interface according to the corresponding relation, so that the corresponding relation between the QoS information of the direct communication interface and the logical channel group identifier is unique.

The terminal is equipment with a wireless communication function, can be deployed on land, and comprises an indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an augmented reality (augmented reality, AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), or the like; but also various forms of UEs, mobile Stations (MSs), terminal devices (terminal devices).

The network side device is a device for providing a wireless communication function for the terminal, including but not limited to: a gNB in 5G, a radio network controller (radio network controller, RNC), a Node B (NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved nodeB, or home node B, HNB), a BaseBand Unit (BBU), a transmission point (transmitting and receiving point, TRP), a transmission point (transmitting point, TP), a mobile switching center, and the like.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In view of the above scenario, the present application provides a system structure diagram for determining a logical channel group identifier, specifically as shown in fig. 2, where the system includes:

A terminal 20, configured to receive a correspondence between QoS information of a direct communication interface configured by a network side device and a logical channel group identifier; and determining the logical channel group identification corresponding to the QoS information of the current direct communication interface according to the corresponding relation.

A network side device 21, configured to determine a correspondence between QoS information of a direct communication interface of a terminal and a logical channel group identifier; and sending the corresponding relation to the terminal.

In the embodiment of the invention, firstly, network side equipment determines the corresponding relation between the QoS information of the direct communication interface of the terminal and the logical channel group identifier, then the network side equipment sends the corresponding relation between the QoS information of the determined direct communication interface and the logical channel group identifier to the terminal, and after the terminal receives the corresponding relation, the terminal determines the logical channel group identifier corresponding to the QoS information of the current direct communication interface of the terminal according to the corresponding relation. Because the network side equipment determines the corresponding relation between the QoS information of the direct communication interface and the logical channel group identifier, the terminal does not determine the LCG ID corresponding to the LC according to the corresponding relation between the PPPP and the LCG ID and the corresponding relation between the PPPR and the LCG ID, but determines the LCG ID corresponding to the LC according to the corresponding relation, so the QoS information of the direct communication interface corresponds to the logical channel group identifier one by one, namely the mapping relation between the logical channel of the direct communication interface and the logical channel group is unique, and the dispatching accuracy is ensured.

The QoS information may be a combination of different values of a plurality of QoS parameters, or may be different values of one or a plurality of QoS parameters. The QoS parameters may be PPPP, PPPR, or other direct communication interface QoS parameters newly introduced later.

When the QoS parameters are PPPP and PPPR, the QoS information may be different combinations of values of PPPP and PPPR, or may be different values of one or more PPPP or PPPR.

The embodiment of the invention is illustrated by taking PPPP and PPPR as examples of QoS parameters.

The method for determining the logical channel group identifier in the two scenarios that the QoS information is different value combinations of a plurality of QoS parameters and the QoS information is different value of one or a plurality of QoS parameters is described below.

In a first scenario, the QoS information is a combination of different values of a plurality of QoS parameters.

For example, PPPP and PPPR are respectively 5 levels, which are respectively level 0, level 1, level 2, level 3, and level 4, then different values of QoS parameters are combined into 25 groups, for example, PPPP is level 0, PPPR is level 1, and then the values of QoS parameters are combined into {0,1}; the PPPP has a level of 0 and the PPPR has a level of 2, and the combination of the values of the QoS parameters is {0,2}.

When the QoS information is different value combinations of a plurality of QoS parameters, two modes of determining the logical channel group identifier exist, wherein one mode is that network side equipment determines the corresponding relation between the different value combinations of all the direct communication interface QoS parameters and the logical channel group identifier; the second mode is to determine the corresponding relation between different value combinations of the QoS parameters of the current direct communication interface of the terminal and the logical channel group identifier for the network side device, and the first mode and the second mode are respectively described below.

In one mode, the network side equipment determines the corresponding relation between different value combinations of all the direct communication interface QoS parameters and the logical channel group identification.

Firstly, network side equipment determines different values of a plurality of QoS parameters of a direct communication interface, and then determines different value combinations of the QoS parameters of the direct communication interface according to the determined different values of the QoS parameters.

For example, the network side device determines that the QoS parameters PPPP and PPPR of the direct communication interface are respectively 8 classes, class 0, class 1, class 2, class 3, class 4, class 5, class 6 and class 7, and then the QoS parameters are combined into 64 groups, and the network side device determines the combination of the QoS parameters of the 64 groups of the direct communication interface, for example, the combination {0,0}, {0,1}, {0,2}, and so on.

After the network side equipment determines different value combinations of the QoS parameters of the direct communication interface, the network side equipment generates corresponding relations between the different value combinations of the QoS parameters of the direct communication interface and the logical channel group identifications, which are required to be configured for the terminal, according to the logical channel group identifications corresponding to the determined different value combinations of the QoS parameters of the direct communication interface.

That is, after combining the different QoS parameters of the direct communication interface, the network side device configures the correspondence between the QoS parameter value combination of the direct communication interface and the logical channel group identifier according to the QoS parameter value combination of the direct communication interface.

The mode of configuring the corresponding relation between the QoS parameter combination of the direct communication interface and the logical channel group identifier by the network side equipment can be configured through broadcasting or special signaling.

It should be noted that, the embodiments of the present invention may be applied to a manner of configuring QoS parameters of a direct communication interface for a network device.

The correspondence between the QoS parameter combinations of the direct communication interfaces and the logical channel group identifications is described below in conjunction with table 1. As shown in table 1, a table of correspondence between QoS parameter combinations of a first direct communication interface and logical channel group identifiers is provided in an embodiment of the present invention.

Table 1 is a table of correspondence between QoS parameter combinations of a direct communication interface and logical channel group identifications

In table 1, the first row indicates the values of the QoS parameters PPPR of the direct communication interface, the first row indicates the values of the QoS parameters PPPP of the direct communication interface, and as can be seen from table 1, the values of PPPR and PPPP are respectively 8 levels, which are respectively level 0, level 1, level 2, level 3, level 4, level 5, level 6, level 7, and the combinations of different values of the QoS parameters are 64 groups, for example, the combinations { pppp=0, pppr=0 }, { pppp=0, pppr=1 }, { pppp=0, pppr=2 }, etc.

The number of logical channel groups is 4, and the logical channel group identifiers corresponding to the 4 logical channel groups are also 4, and are respectively 0,1,2 and 3. As can be seen from table 1, each combination of values of PPPP and PPPR corresponds to a logical channel group identifier, for example, a logical channel group identifier corresponding to a combination { pppp=0, pppr=0 } is 0, a logical channel group identifier corresponding to a combination { pppp=0, pppr=1 } is 0, and a logical channel group identifier corresponding to a combination { pppp=0, pppr=2 } is 1.

The network side equipment generates the corresponding relation between different value combinations of the QoS parameters of the direct communication interface which are required to be configured for the terminal and the logical channel group identification, and then sends the corresponding relation to the terminal.

The terminal firstly receives the corresponding relation between different value combinations of the QoS parameters of the direct communication interface and the logical channel group identifier sent by the network side equipment, and then determines different value combinations of a plurality of QoS parameters of the current direct communication interface.

The terminal determines different combinations of values of a plurality of QoS parameters of the current direct communication interface, for example, the current QoS parameter PPPR of the terminal is 0,1,2, and the PPPP is 1,2, and then the different combinations of values of a plurality of QoS parameters of the current direct communication interface of the terminal are 6, which are respectively the combination { pppp=0, pppr=1 }, the combination { pppp=0, pppr=2 }, the combination { pppp=1, pppr=1, the combination { pppp=1, pppr=2 }, the combination { pppp=2, pppr=2.

After the terminal determines different value combinations of a plurality of QoS parameters of the current direct communication interface, the terminal determines the logic channel group identifier of the value combination of the QoS parameters of each current direct communication interface according to the corresponding relation between the received different value combinations of the QoS parameters of the direct communication interface and the logic channel group identifier.

For example, the QoS parameters determined by the terminal are set to a combination { pppp=0, pppr=1 }, a combination { pppp=0, pppr=2 }, a combination { pppp=1, pppr=1, a combination { pppp=2 }, a combination { pppp=2, pppr=2 }, a combination { pppp=0, a combination { pppp=1 } with a logical channel group identifier of 0, a combination { pppp=0, a combination { pppr=2 } with a logical channel group identifier of 1, a combination { pppp=1 } with a logical channel group identifier of 0, a combination { pppp=1, a combination { pppr=2 } with a logical channel group identifier of 1, a combination { pppp=2, a combination { pppp=1 } with a logical channel group identifier of 1, a combination { pppp=2, a combination { pppr=2 }.

The logical channel group identifier corresponding to the value combination of the QoS parameters can be uniquely determined, and the corresponding relationship between the logical channel and the logical channel group identifier can be ensured to be in one-to-one correspondence.

In the second mode, the network side equipment determines the corresponding relation between different value combinations of the QoS parameters of the current direct communication interface of the terminal and the logical channel group identification.

Firstly, a terminal determines a plurality of QoS parameters corresponding to a logic channel established or activated by a current direct communication interface, then determines all different value combinations of the plurality of QoS parameters corresponding to the logic channel established or activated by the current direct communication interface, and finally informs auxiliary information for determining all different value combinations of the plurality of QoS parameters corresponding to the logic channel established or activated by the current direct communication interface to network side equipment.

That is, before the network side device configures the correspondence between all the different value combinations of QoS parameters and the logical channel group identifier for the terminal, the terminal sends an auxiliary message to the network side device, where the auxiliary message includes all the different value combinations of QoS parameters corresponding to the logical channel that is currently established or activated by the direct communication interface of the terminal.

For example, when the QoS parameters PPPR corresponding to the logical channel established or activated by the current direct communication interface of the terminal are 2,3, and PPPP is 4,5, the combination of the QoS parameters corresponding to the logical channel established or activated by the current direct communication interface of the terminal is { pppp=2, pppr=4 }, { pppp=3, pppr=4 }, { pppp=2, pppr=5 }, and { pppp=3, pppr=5 }, and the terminal sends the auxiliary information including the combination of the QoS parameters.

The terminal may report the auxiliary information to the network side device in an event-triggered manner, for example, the triggering condition of the auxiliary information reporting is part or all of the following:

the direct communication interface has a newly established logical channel;

the direct communication interface has a released logical channel;

the combination of the QoS parameters corresponding to the logical channels of the current direct communication interface changes.

After the auxiliary information reporting triggering condition triggers the terminal to send auxiliary information to the network side equipment, the network side equipment receives the auxiliary information and determines all different value combinations of a plurality of QoS parameters corresponding to a logic channel established or activated by the current direct communication interface of the terminal.

After the network side equipment determines all different value combinations of a plurality of QoS parameters corresponding to the current direct communication interface established or activated by the terminal, the corresponding relation between the different value combinations of the QoS parameters of the direct communication interface and the logical channel group identification which are required to be configured for the terminal is generated according to the logical channel group identification corresponding to the determined value combination of each QoS parameter.

That is, after combining the determined QoS parameters corresponding to the logical channel established or activated by the current direct communication interface of the terminal, the network side device configures the corresponding relationship between the QoS parameter combination of the direct communication interface and the logical channel group identifier according to the QoS parameter combination of the direct communication interface.

The correspondence between the QoS parameter combinations of the direct communication interfaces and the logical channel group identifications is described below in conjunction with table 2.

Let PPPP and PPPR be 8 grades, grade 0, grade 1, grade 2, grade 3, grade 4, grade 5, grade 6, grade 7 respectively; the number of the logical channel group identifiers is 4, and is 0,1,2 and 3 respectively.

The direct communication interface of the terminal has three logic channels, and the supported PPPP/PPPR combination comprises: { pppp=0, pppr=1 }, { pppp=2, pppr=3 }, { pppp=3, pppr=3 }. The mapping relationship of the QoS parameter combinations and the logical channel group identities is configured based on the QoS parameter combinations as shown in table 2.

Table 2 is a table of correspondence between QoS parameter value combinations and logical channel group identifiers of a second direct communication interface according to an embodiment of the present invention.

Table 2 shows the correspondence between the combination of QoS parameter values of another direct communication interface and the logical channel group identifier

In table 2, the first row represents the value of the QoS parameter PPPR of the direct communication interface, the first row represents the value of the QoS parameter PPPP of the direct communication interface, and as can be seen from table 2, the logical channel group identifier corresponding to the QoS parameter combination { pppp=0, pppr=1 } is 0; the logical channel group identifier corresponding to the QoS parameter combination { pppp=2, pppr=3 } is 1; the logical channel group corresponding to the QoS parameter combination { pppp=3, pppr=3 } is identified as 2.

The network side equipment configures the corresponding relation between the QoS parameter combination of the current direct communication interface of the terminal and the logical channel group identifier for the terminal and then sends the corresponding relation to the terminal.

The terminal determines different value combinations of a plurality of QoS parameters of the current direct communication interface, and determines the logic channel group identifier of the value combination of the QoS parameters of each current direct communication interface of the terminal according to the corresponding relation between the received different value combinations of the QoS parameters of the current direct communication interface of the terminal and the logic channel group identifier.

For example, for the QoS parameter combination { pppp=2, pppr=3 }, the terminal determines, according to the received correspondence, such as table 2, that the logical channel group identifier corresponding to the QoS parameter combination { pppp=2, pppr=3 } is 1, and for the QoS parameter combination { pppp=3, pppr=3 }, the terminal determines, according to the received correspondence, such as table 2, that the logical channel group identifier corresponding to the QoS parameter combination { pppp=3, pppr=3 } is 2.

In scenario two, the QoS information is a different value of one or more QoS parameters.

When the QoS information is different values of one or more QoS parameters, two modes of determining the logical channel group identifier exist, wherein one mode is to determine the corresponding relation between the different values of one or more QoS parameters of all direct communication interfaces and the logical channel group identifier for the network side equipment; the second mode is that the network side device determines the corresponding relationship between the different values of one or more QoS parameters of the direct communication interface and the logical channel group identifier according to the different values of one or more QoS parameters of the current direct communication interface of the terminal, and the first mode and the second mode are respectively described below.

In the first mode, firstly, the network side equipment determines different values of all the QoS parameters of the direct communication interface.

For example, if the QoS parameters PPPP of the direct communication interface have 8 levels, the values of the QoS parameters PPPP are 0,1,2,3,4,5,6,7; the QoS parameters PPPR of the direct communication interface have 5 levels, and the values of the QoS parameters PPPR are 0,1,2,3, and 4.

After the different values of all the direct communication interface QoS parameters are determined, the network side equipment configures the corresponding relation between the different values of all the direct communication interface QoS parameters and the logical channel group identification.

The manner in which the network side device configures the correspondence may be configured by broadcast or control signaling.

The following examples illustrate the correspondence between different values of QoS parameters of all direct communication interfaces and logical channel group identifiers.

For example, the QoS parameters PPPP and PPPR of the direct communication interface are respectively 8 levels, level 0, level 1, level 2, level 3, level 4, level 5, level 6, and level 7; the number of logical channel groups is 4, and is 0,1,2 and 3 respectively.

The correspondence between the QoS parameters PPPP and the logical channel group identities for the direct communication interface is shown in table 3. In table 3, when the QoS parameter PPPP of the direct communication interface is 0, the corresponding logical channel group is identified as 0, when the QoS parameter PPPP of the direct communication interface is 1, the corresponding logical channel group is identified as 0, and when the QoS parameter PPPP of the direct communication interface is 2, the corresponding logical channel group is identified as 1.

		4	2

		6	3

Table 3 shows the correspondence between PPPP and logical channel group identifier

The correspondence between the QoS parameters PPPR and the logical channel group identities for the direct communication interface is shown in table 4. In table 4, when the QoS parameter PPPR of the direct communication interface is 0, the corresponding logical channel group is identified as 0, when the QoS parameter PPPR of the direct communication interface is 1, the corresponding logical channel group is identified as 0, and when the QoS parameter PPPR of the direct communication interface is 2, the corresponding logical channel group is identified as 1.

Table 4 is a table of correspondence between PPPR and logical channel group identifications

And the network side equipment generates a corresponding relation to be configured for the terminal according to the determined different values of each QoS parameter and the logic channel group identifier, and then sends the corresponding relation to the terminal.

After receiving the corresponding relation between different values of each QoS parameter and the logical channel group identifier sent by the network side equipment, the terminal determines the QoS parameter which the terminal needs to use, namely the current direct communication interface QoS parameter of the terminal.

The method for determining the QoS parameters to be used by the terminal is determined according to the method notified by the network side equipment or agreed by the protocol.

After the QoS parameters needed by the terminal are determined, the terminal determines the logical channel group identifier corresponding to the value of the QoS parameters needed by the terminal according to the corresponding relation between the different value of each QoS parameter and the logical channel group identifier, which are sent by the network side equipment.

For example, the QoS parameter corresponding to the logical channel of the direct communication interface is pppp=1, pppr=0, the determined logical channel group is identified as 0 according to table 3, and the determined logical channel group is identified as 0 according to table 4, so that the logical channel group corresponding to the logical channel is identified as 0.

When the terminal determines the logical channel group identifier corresponding to the value of the QoS parameter to be used by the terminal according to the correspondence relationship sent by the network side device, there is a possibility that the determined correspondence relationship between the logical channel and the logical channel group identifier is not unique.

For example, the QoS parameter corresponding to the logical channel of the direct communication interface is pppp=1, pppr=3, the logical channel group identifier corresponding to the determined pppp=1 is 0 according to the corresponding relation of table 3, the logical channel group identifier corresponding to the determined pppr=3 is 2 according to the corresponding relation of table 4, and at this time, the logical channel group identifier determined by the logical channel of the direct communication interface through the corresponding relation is not unique.

In order to solve the problem that the logical channel group identification determined by the logical channel of the direct communication interface through the corresponding relation is not unique, when the QoS parameters are multiple, the network side device can send the indication information of the QoS parameters which are preferentially used to the terminal.

In implementation, when determining the priority of the QoS parameter, the corresponding relationship between the QoS parameter PPPP of the direct communication interface and the logical channel group identifier may be prioritized, or the corresponding relationship between the QoS parameter PPPR of the direct communication interface and the logical channel group identifier may be prioritized.

For example, when the QoS parameters are plural, the network side device sends the indication information of the priority of the corresponding relation between the QoS parameters PPPP of the direct communication interface and the logical channel group identifier to the terminal, so when the logical channel group identifier corresponding to pppp=1 determined according to the corresponding relation of table 3 is 0, and when the logical channel group identifier corresponding to pppr=3 determined according to the corresponding relation of table 4 is 2, the logical channel group identifier corresponding to the logical channel is 0.

In a second mode, the network side device determines the corresponding relationship between the different values of one or more QoS parameters of the direct communication interface and the logical channel group identifier according to the different values of one or more QoS parameters of the current direct communication interface of the terminal.

Firstly, a terminal determines one or more QoS parameters corresponding to a logic channel established or activated by a current direct communication interface, then determines all different values of the one or more QoS parameters corresponding to the logic channel established or activated by the current direct communication interface, and finally informs network side equipment of auxiliary information used for determining all different values of the one or more QoS parameters corresponding to the logic channel established or activated by the current direct communication interface.

That is, before the network side device configures the correspondence between all the different values of the QoS parameters and the logical channel group identifier for the terminal, the terminal sends an auxiliary message to the network side device, where the auxiliary message includes all the different values of one or more QoS parameters corresponding to the logical channel that is currently established or activated by the direct communication interface of the terminal.

For example, the QoS parameters PPPP and PPPR of the direct communication interface are respectively 8 levels, the number of logical channels is 4, the number of logical channels of the direct communication interface is 3, the combination of the supported QoS parameters PPPP and PPPR is { pppp=0, pppr=1 }, { pppp=2, pppr=3 }, { pppp=3, pppr=3 }, and if the QoS parameters PPPP corresponding to the logical channels established or activated by the current direct communication interface of the terminal are 0,2,3, and PPPR is 1,3, the terminal sends the auxiliary information including the QoS parameters with different values pppp=0, pppp=2, pppp=3, pppr=1, and pppr=3 to the network side device.

The terminal may report the auxiliary information to the network side device in an event-triggered manner, for example, the auxiliary information reporting triggering condition is part or all of the following:

the direct communication interface has a newly established logical channel;

The direct communication interface has a released logical channel;

After the triggering terminal sends the auxiliary information to the network side equipment, the network side equipment receives the auxiliary information and determines all different values of a plurality of QoS parameters corresponding to the logic channels established or activated by the current direct communication interface of the terminal according to the auxiliary information.

After the network side equipment determines all different values of a plurality of QoS parameters corresponding to the logic channels established or activated by the current direct communication interface of the terminal, the corresponding relation between the different values of the QoS parameters of the direct communication interface which are required to be configured for the terminal and the logic channel group identification is generated according to the logic channel group identification corresponding to the determined value of each QoS parameter.

The mode of configuring the corresponding relation between the QoS parameter value of the direct communication interface and the logical channel group identifier by the network side equipment can be configured through broadcasting or special signaling.

The correspondence between the QoS parameters of the direct communication interface and the logical channel group identities is described below with reference to tables 5 and 6.

For example, the QoS parameters PPPP and PPPR of the direct communication interface are respectively 8 levels, the number of logical channels is 4, the number of logical channels of the direct communication interface is 3, the combination of the supported QoS parameters PPPP and PPPR is { pppp=0, pppr=1 }, { pppp=2, pppr=3 }, { pppp=3, pppr=3 }, and then the network side device determines that the different values of the QoS parameters of the current direct communication interface of the terminal are pppp=0, pppp=2, pppp=3, pppr=1, pppr=3.

The corresponding relation between different direct communication interface QoS parameters PPPP and logical channel group identifications is configured by the network side equipment, and is shown in a table 5, wherein in the table 5, when the QoS parameters PPPP=0, the corresponding logical channel group identifications are 0, when the QoS parameters PPPP=2, the corresponding logical channel group identifications are 1, and when the QoS parameters PPPP=3, the corresponding logical channel group identifications are 1;

PPPP	LCG ID
		0	0
2	1
		3	1

table 5 is a table of correspondence between PPPP and logical channel group identifiers

The corresponding relation between different direct communication interface QoS parameters PPPR and the logical channel group identifiers is shown in a table 6, in the table 6, when the QoS parameters PPPR=1, the corresponding logical channel group identifier is 0, and when the QoS parameters PPPR=3, the corresponding logical channel group identifier is 2.

PPPR	LCG ID
		1	0
3	2

Table 6 is a table of correspondence between PPPR and logical channel group identifier

For example, the QoS parameter corresponding to the logical channel of the direct communication interface is pppp=0, pppr=1, according to table 5, the determined logical channel group is identified as 0, according to table 6, the determined logical channel group is identified as 0, and then the logical channel group corresponding to the logical channel is identified as 0.

For example, the QoS parameter corresponding to the logical channel of the direct communication interface is pppp=0, pppr=3, the logical channel group identifier corresponding to the determined pppp=0 is 0 according to the corresponding relation of table 4, the logical channel group identifier corresponding to the determined pppr=3 is 2 according to the corresponding relation of table 6, and at this time, the logical channel group identifier determined by the logical channel of the direct communication interface through the corresponding relation is not unique.

The above description is that the terminal determines the logical channel group identifier corresponding to the QoS information of the current direct communication interface according to the correspondence, and after the terminal determines the logical channel group identifier corresponding to the QoS information of the direct communication interface, the terminal may determine the correspondence between the logical channel of the direct communication interface and the logical channel group according to the determined logical channel group identifier corresponding to the QoS information of the direct communication interface, so that the terminal may report the sidlink BSR.

In implementation, when the terminal performs the buffer status reporting of the direct communication link, after the direct communication link of the terminal meets the trigger condition of the buffer status reporting, the buffer status reporting of the direct communication link is organized. Because the network side equipment already knows the corresponding relation between the QoS information of the direct communication interface and the logical channel group identifier, the corresponding relation between the QoS information and the logical channel group identifier is not required to be contained in the reporting of the buffer state of the direct communication link, and the corresponding relation between the direct communication interface and the logical channel group identifier is unique, so that the accuracy of scheduling is ensured.
