Description

Configuration method, device and system

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a configuration method, device, and system.

Background

In a long term evolution (long term evolution, LTE) system or a New Radio (NR) system, a communication interface between a terminal device and a base station is called Uu port. The link on the Uu port where the terminal device sends data to the base station is called Uplink (UL), and the link where the terminal device receives data sent by the base station is called Downlink (DL). Further, the communication interface between the terminal device and the terminal device is referred to as a PC5 port. The link between the terminal device on the PC5 port and the terminal device for transmitting data is called Sidelink (SL). The PC5 port is generally used for a scenario where a vehicle communicates with the outside (vehicle to everything, V2X), or a device-to-device (D2D) communication or the like can perform direct communication between devices.

As shown in fig. 1a, for communications over the Uu port, the terminal device needs to trigger a scheduling request (scheduling request, SR) and request an uplink grant from the base station by sending an SR, for example, when the terminal device has uplink data to send but no uplink grant (UL grant) is available. After receiving the uplink grant, the terminal device may send an UL buffer status report (buffer status report, BSR) to the base station through the uplink grant, where the base station is configured to further allocate an UL grant to the terminal device according to the UL BSR, so that the terminal device sends UL data on the corresponding UL grant.

As shown in fig. 1b, for the communication of the PC5 port, if the base station configures the terminal device 1 with a resource allocation scheme based on base station scheduling, when the terminal device 1 has side uplink data to transmit but no side uplink grant (SL grant) is available, the terminal device 1 also needs to trigger the SR and request the uplink grant from the base station by transmitting the SR. After receiving the uplink grant, terminal device 1 may transmit a SL BSR to the base station through the uplink grant, and the base station is configured to further allocate a SL grant to terminal device 1 according to the SL BSR, so that terminal device 1 continues to transmit SL data on the corresponding SL grant.

As can be seen from the flow shown in fig. 1a and the flow shown in fig. 1b, both the uplink data transmission on the Uu port and the side uplink data transmission on the PC5 port require that the SR be sent over the Uu port to request the corresponding link grant from the base station. Wherein the terminal device may send the SR through dedicated SR resources on a physical uplink control channel (physical uplink control channel, PUCCH) configured by the base station for the terminal device.

In the prior art, there are a SR-related configuration for use when a Uu port of an LTE system transmits an SR for uplink data transmission of the Uu port, and a SR-related configuration for use when a Uu port of an NR system transmits an SR for uplink data transmission of the Uu port, but there is no relevant solution at present how to configure a SR-related configuration for use when a Uu port of an NR system transmits an SR for side uplink data transmission of the PC5 port.

The embodiment of the application provides a configuration method, equipment and system, which can be used for configuring related configuration of SR (scheduling request) used when a Uu port of an NR (network management) system sends the SR for side-uplink data transmission of a PC5 port.

Furthermore, if the logical channel associated with the second identifier triggers the SL BSR and triggers the SR, the SR configuration of the terminal device for the SR may be the SR configuration corresponding to the SR identifier mapped by the second identifier; the SR resource configuration for the SR by the terminal device may be one or more SR resource configurations associated with the SR configuration. That is, the terminal device may determine the SR configuration and the SR resource configuration used when transmitting the SR for the side-uplink data transmission of the PC5 port at the Uu port of the NR system according to the second identification and the SR identification mapped by the second identification, so that the SR may be transmitted at the Uu port of the NR system according to the determined SR configuration and SR resource configuration.

With reference to the first aspect, in one possible design, the first message further includes quality of service QoS information corresponding to the first identifier. The QoS information may be used to determine a scheduling request SR identity to which the second identity is mapped.

With reference to the first aspect or the possible designs of the first aspect, in one possible design, if there is a mapping relationship between the first identifier and the second identifier, the second message further includes or indicates the mapping relationship between the first identifier and the second identifier. Furthermore, the terminal device may learn the mapping relationship between the first identifier and the second identifier.

With reference to the first aspect or the possible designs of the first aspect, in one possible design, the first message further includes destination information, wherein the first identification is associated with the destination information. The destination information is used for enabling the network device to distinguish the destination to which the first identifier belongs, so that one or more of SR configuration and SR resource configuration associated with the SR configuration are configured for the terminal device according to the destination information and the first identifier.

With reference to the first aspect or the possible designs of the first aspect, in one possible design, the second message further includes the destination information, wherein the second identifier is associated with the destination information, and the SR identifier mapped by the second identifier is associated with the destination information.

With reference to the first aspect or the possible designs of the first aspect, in one possible design, the first message further includes source information and destination information, wherein the first identifier is associated with the source information and the first identifier is associated with the destination information.

For example, if the network device has previously sent the SR configuration corresponding to the SR identifier mapped by the second identifier included in the second message to the terminal device, but needs to associate a new SR resource configuration with the SR configuration corresponding to the SR identifier, then the second message also needs to include one or more SR resource configurations associated to the SR configuration corresponding to the SR identifier.

Detailed Description

For convenience in understanding the schemes in the embodiments of the present application, a brief description or definition of the related art is given first as follows:

first, SR-related configuration

In the embodiment of the application, relevant configurations of SR used in SR for side-link data transmission for PC5 port transmitted at Uu port of NR system include SR configuration (scheduling request config) and SR resource configuration (scheduling request resource config).

The SR configuration is included in the MAC configuration of the cell group configuration (MAC-CellGroupConfig). Each MAC entity has a MAC configuration. A maximum of 8 SR configurations may be included in each MAC configuration. The SR configuration includes:

an SR identification (SR ID) for identifying or corresponding to one SR configuration;

an SR prohibit counter (SR prohibit timer) for controlling a time interval of SR transmission;

the maximum number of SR transmissions (SR trans Max) is used to control the maximum number of SR transmissions.

Wherein the SR resource configuration is contained in a PUCCH configuration (PUCCH-config). A maximum of 8 SR resource configurations may be included in one PUCCH configuration. The concept of bandwidth part (BWP) was introduced on the Uu port of the NR system. A maximum of 4 BWP may be configured on each serving cell of the terminal device. Each BWP on a serving Cell where PUCCH can be configured, i.e. a PUCCH Cell (including PCell/PSCell and PUCCH SCell) of the terminal device, has an independent PUCCH configuration and thus also an independent SR resource configuration. The SR resource configuration includes:

an SR resource identification (SR resource ID) for identifying a configuration of an SR resource;

a period and offset (periodicity and offset) for determining a time domain resource location of the SR;

physical uplink control channel resources (PUCCH resource ID) for determining frequency domain resource locations of SRs.

As shown in fig. 1c, each SR configuration under each MAC entity of the terminal device corresponds to one or more uplink logical channels, and each uplink logical channel is mapped to 0 or 1 SR configuration. One SR configuration contains or associates a set of SR resource configurations (which may also be referred to as PUCCH SR resource set) for different BWP and serving cells. After one MAC entity of the terminal equipment triggers the UL BSR and further triggers the SR, the terminal equipment determines corresponding SR configuration and SR resource configuration according to a logic channel triggering the UL BSR. If the SR configuration and the associated SR resource configuration are configured for the logical channel triggering the UL BSR, that is, the dedicated SR resource for transmitting the SR is effectively used by the terminal device for the logical channel triggering the UL BSR, the terminal device transmits the SR through the dedicated SR resource. If the terminal device has multiple effective dedicated SR resources overlapping in time for the logical channel triggering the UL BSR, which dedicated SR resource is selected to transmit the SR is determined by the terminal device implementation, which embodiment of the present application is not specifically limited.

Wherein, in the description of the present application, "/" means that the related objects are in a "or" relationship, unless otherwise specified, for example, a/B may mean a or B; the term "and/or" in this application is merely an association relation describing an association object, and means that three kinds of relations may exist, for example, a and/or B may mean: there are three cases, a alone, a and B together, and B alone, wherein a, B may be singular or plural. Also, in the description of the present application, unless otherwise indicated, "a plurality" means two or more than two. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", and the like are used to distinguish the same item or similar items having substantially the same function and effect. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

The technical scheme of the embodiment of the application can be applied to various communication systems. For example: orthogonal frequency division multiple access (orthogonal frequency-division multiple access, abbreviated OFDMA), single carrier frequency division multiple access (single carrier FDMA, abbreviated SC-FDMA), and other systems, among others. The term "system" may be used interchangeably with "network". The OFDMA system may implement wireless technologies such as evolved universal wireless terrestrial access (evolved universal terrestrial radio access, E-UTRA for short), ultra mobile broadband (ultra mobile broadband, UMB for short), and the like.

Further, after the terminal device 40 receives the second message from the network device 30, if the logical channel associated with the second identifier triggers the SL BSR and triggers the SR, the SR configuration used by the terminal device 40 for the SR is the SR configuration corresponding to the SR identifier mapped by the second identifier; the SR resource configuration for the SR by the terminal device 40 is the one or more SR resource configurations with which the SR configuration is associated. That is, the terminal device 40 may determine the SR configuration and the SR resource configuration used when transmitting the SR for the side-uplink data transmission of the PC5 port at the Uu port of the NR system based on the second identification and the SR identification mapped by the second identification, so that the SR may be transmitted at the Uu port of the NR system based on the determined SR configuration and SR resource configuration.

Based on this, the present embodiment provides the following two configuration methods. The following terminal devices may correspond to the terminal device 1 herein, and are described in detail herein, and will not be described in detail herein.

It should be noted that, in the embodiments described below, the names of the messages between the network elements or the names of the parameters in the messages are only an example, and may be other names in specific implementations, which are not limited in the embodiments of the present application.

As shown in fig. 5, a configuration method provided in an embodiment of the present application includes the following steps:

s501, the terminal equipment sends a first message to the base station. Correspondingly, the base station receives a first message from the terminal device. Wherein the first message includes a first identification.

The first message may be, for example, a side-uplink UE information (sidelink UE information) message.

Optionally, the first message may further include QoS information corresponding to the first identifier. The relevant descriptions of QoS information may refer to the brief introduction of the specific embodiments, and are not repeated herein.

In a possible implementation manner, destination information of the V2X service may be further included in the first message. The destination information is associated with the first identification. The destination information is used for enabling the base station to distinguish the destination to which the first identifier belongs, so that one or more of SR configuration and SR resource configuration associated with the SR configuration are configured for the terminal equipment according to the destination information and the first identifier.

The destination information in the embodiments of the present application may be, for example, a layer two destination identifier (destination L2 ID) or an index value mapped by the layer two destination identifier, which is not specifically limited in the embodiments of the present application.

It should be noted that, in the embodiment of the present application, the association may also be described as mapping, corresponding, binding, etc., that is, in the embodiment of the present application, the association, mapping, corresponding, binding, etc. may be understood as different expression modes with the same meaning, which are collectively described herein, and are not described in detail herein.

Alternatively, in another possible implementation manner, source information and destination information of the V2X service may be further included in the first message. The source information is associated with the first identification and the destination information is associated with the first identification. The source information and the destination information are used for enabling the base station to distinguish a combination of the source and the destination to which the first identifier belongs, so that the SR configuration is configured for the terminal equipment according to the combination of the source information and the destination information and one or more of the SR resource configurations associated with the SR configuration.

For example, the source information in the embodiment of the present application may be a layer two source identifier (source L2 ID) or an index value mapped by the layer two source identifier, which is not specifically limited in the embodiment of the present application.

Optionally, the first message may further include indication information, where the indication information is used to indicate whether a transmission mode corresponding to each QoS flow or each QoS identifier is unicast transmission, multicast transmission or broadcast transmission.

S502, the base station sends a second message to the terminal equipment. Correspondingly, the terminal device receives the second message from the base station. The second message includes a second identifier and an SR identifier mapped by the second identifier, the SR identifier corresponds to one SR configuration, the SR configuration is associated with one or more SR resource configurations, the first identifier is the same as the second identifier, or a mapping relationship exists between the first identifier and the second identifier.

The second message may be, for example, a radio resource control (radio resource control, RRC) reconfiguration (RRC reconfiguration) message.

Optionally, in the embodiment of the present application, if the first message includes destination information of the V2X service, the second message may further include destination information of the V2X service. The destination information is associated with the second identity and the SR identity mapped by the second identity. The destination information is used for enabling the terminal equipment to distinguish the destination to which the SR identifier mapped by the second identifier belongs, so that the SR configuration used for SR transmission and one or more SR resource configurations associated with the SR configuration are determined according to the destination information and the SR identifier mapped by the second identifier.

Or optionally, in the embodiment of the present application, if the first message includes source information and destination information of the V2X service, the second message may further include source information and destination information of the V2X service. The source information is associated with the second identity and the SR identity mapped by the second identity, the destination information is associated with the second identity and the SR identity mapped by the second identity. Wherein the source information and the destination information are used for enabling the terminal device to distinguish a combination of the source and the destination to which the SR identifier mapped by the second identifier belongs, so that the SR configuration used for SR transmission and one or more SR resource configurations associated with the SR configuration are determined according to the combination of the source information and the destination information and the SR identifier mapped by the second identifier.

The above configuration method will be described in detail in several different cases.

Case one: the first identity is an identity of the QoS flow.

Taking the V2X service AS an example, when the terminal device has V2X service to be transmitted, an upper layer (an application layer, or V2X layer) of the terminal device maps the V2X service to one or more QoS flows, and notifies an access layer (AS) layer of an identifier of each QoS flow and QoS information corresponding to the QoS flow. When the upper layer of the terminal device delivers the V2X service packet to the AS, the AS layer is informed of the QoS flow identifier to which the V2X service packet belongs.

Optionally, when the upper layer of the terminal device submits the V2X service packet to the AS, the AS layer is informed that the transmission mode adopted by the V2X service packet is unicast transmission, multicast transmission or broadcast transmission; or when the upper layer of the terminal equipment informs the AS layer of the identifier of each QoS flow and the QoS information corresponding to the QoS flow, the AS layer is informed of whether the transmission mode adopted by the V2X service packet on the QoS flow is unicast transmission, multicast transmission or broadcast transmission.

Optionally, the upper layer may inform the AS layer of the transmission mode adopted by the V2X service packet in an explicit manner, or may inform the AS layer of the transmission mode adopted by the V2X service packet in an implicit manner, that is, if a service packet is delivered to the AS layer, the upper layer informs the AS layer of the identifier of the QoS flow to which the service packet belongs, which means that the transmission mode of the service packet is unicast transmission; conversely, if a service packet is delivered to the AS layer, the upper layer informs the AS layer that the QoS of the QoS information of the service packet is the same, then the transmission mode of the service packet is multicast transmission or broadcast transmission. This description applies to all embodiments of the present application, and is generally described herein, and will not be repeated herein.

Optionally, when the upper layer of the terminal device submits the V2X service packet to the AS, the AS layer is simultaneously informed of the layer two source identifier of the V2X service packet. Or, alternatively, when the upper layer of the terminal device submits the V2X service packet to the AS, the AS layer is notified of the layer two source identifier and the layer two destination identifier of the V2X service packet at the same time.

Further, the AS layer of the terminal device triggers the first message and requests resources for V2X side uplink communication from the base station through the first message. The first message includes a first identifier, which is an identifier of each QoS flow mapped by the V2X service to be transmitted by the terminal device. Optionally, the first message may further include QoS information corresponding to the identifier of each QoS flow. Optionally, the first message may further include destination information of the V2X service; alternatively, the first message may further include source information and destination information of the V2X service, and the related description may refer to step S501 described above, which is not described herein again.

Optionally, the first message further includes indication information, where the indication information is used to indicate whether the transmission mode of the V2X service packet corresponding to each QoS flow or the identifier of each QoS flow is unicast transmission, multicast transmission or broadcast transmission.

Taking any one QoS flow of one or more QoS flows mapped by a V2X service to be transmitted by a terminal device as an example, after the base station receives a first message from the terminal device, the base station corresponds to the following several different processing mechanisms.

Sub-case a: the second identity is an identity of the logical channel group.

After receiving the first message from the terminal equipment, the base station determines a logic channel group mapped by a QoS flow corresponding to the identifier of a certain QoS flow in the first message, and determines the SR related configuration mapped by the logic channel group according to the QoS information corresponding to the identifier of the QoS flow. Further, the base station transmits a second message to the terminal device, where the second message includes an identifier of a logical channel group mapped by the QoS flow and an SR identifier mapped by the identifier of the logical channel group.

Optionally, the second message may further include a mapping relationship between the identifier of the QoS flow and the identifier of the corresponding logical channel group, or in other words, the second message may further include an identifier of the QoS flow having a mapping relationship with the identifier of the logical channel group.

Illustratively, the base station configures the configuration of the logical channel group for the terminal device. Wherein the configuration of the logical channel group at least comprises the identification of the QoS flow mapped to the logical channel group and the identification of the SR mapped by the logical channel group. Optionally, the configuration of the logical channel group further includes an identification of the logical channel group.

Or, by way of example, the base station configures, for the terminal device, the identifier of the logical channel group to which the identifier of the QoS flow is mapped, and configures, for the terminal device, the configuration of the logical channel group; the configuration of the logic channel group at least comprises the identification of the SR mapped by the logic channel group; optionally, the configuration of the logical channel group further includes an identification of the logical channel group.

Alternatively, in the embodiment of the present application, different QoS flows may correspond to the same or different logical channel groups, and SR identifiers mapped by the identifiers of the different logical channel groups may be the same or different. For example, the mapping relationship of the QoS flow identifier, the logical channel group identifier, and the SR identifier may be as shown in table one.

List one

It should be noted that table one is only an exemplary table storage format, and other table storage formats or non-table storage formats are also possible. For example, as shown in table two, the identifier of each QoS flow is stored in one-to-one correspondence with the identifier of each logical channel group and the SR identifier, and the storage form of the correspondence is not specifically limited in the embodiment of the present application. This description applies to all embodiments of the present application, and is generally described herein, and will not be repeated herein.

Watch II

Identification of QoS flows	Identification of logical channel groups	SR identification
			QoS flows identification 1	Identification 1 of logical channel group	SR label 1
Identification 2 of QoS flows	Identification 1 of logical channel group	SR label 1
			QoS flow identification 3	Identification 2 of logical channel group	SR label 2
QoS flows identification 4	Identification 3 of logical channel group	SR label 2

Optionally, in the embodiment of the present application, before step S501, the base station may have sent the SR configuration corresponding to the SR identifier to the terminal device, or the base station may have sent the SR configuration corresponding to the SR identifier and the SR resource configuration associated with the SR configuration to the terminal device, which is not limited in particular in the embodiment of the present application. This description applies to the embodiments of the present application and the following embodiments, and is generally described herein, and will not be repeated herein.

Optionally, in the embodiment of the present application, if the base station has previously sent the SR configuration corresponding to the SR identifier mapped by the identifier of the logical channel group included in the second message to the terminal device, but for the logical channel group mapped by the SR identifier, it is necessary to associate a new SR resource configuration with the SR configuration corresponding to the SR identifier, and then the second message also needs to include one or more SR resource configurations associated to the SR configuration corresponding to the SR identifier. The one or more SR resource configurations are included in a PUCCH configuration in an uplink BWP of a Uu port configured by the base station for the terminal device.

Or optionally, in the embodiment of the present application, if the base station does not configure, for the terminal device, the SR configuration corresponding to the SR identifier mapped by the logical channel group included in the second message and the SR resource configuration associated with the SR configuration before, the second message further needs to include the SR configuration corresponding to the SR identifier and one or more SR resource configurations associated with the SR configuration. The one or more SR resource configurations are included in a PUCCH configuration in an uplink BWP of a Uu port configured by the base station for the terminal device.

Optionally, in the embodiment of the present application, if the first message includes destination information of the V2X service, the second message may further include destination information of the V2X service. Alternatively, in the embodiment of the present application, if the first message includes source information and destination information of the V2X service, the second message may also include source information and destination information of the V2X service, and the description thereof may refer to step S502 described above, which is not repeated herein.

After receiving the second message from the base station, the terminal device establishes the side uplink radio bearer to which the QoS flow is mapped. Exemplary may include: a packet data convergence protocol (packet data convergence protocol, PDCP) entity that establishes the side-link radio bearer, a radio link control (radio link control, RLC) entity that establishes the side-link radio bearer, and a logical channel of the side-link radio bearer. The mapping relationship between QoS flows and side uplink radio bearers may be one-to-one mapping or many-to-one mapping.

In the embodiment of the application, the identification of the side link radio bearer (SL DRB ID) and the identification of the logical channel of the side link radio bearer (logical channel ID) are determined by the terminal device itself.

Further, the terminal device may configure, according to the mapping relationship between the identifier of the QoS flow and the identifier of the logical channel group included in the second message, the logical channel group to which the logical channel of the side uplink radio bearer mapped by the QoS flow belongs to be the logical channel group corresponding to the QoS flow.

Further, the terminal device may determine, according to the SR identifier mapped by the identifier of the logical channel group included in the second message, that the SR identifier mapped by the logical channel of the side uplink radio bearer mapped by the QoS flow is the SR identifier mapped by the identifier of the logical channel group.

If the logical channel of the side link radio bearer mapped by the QoS flow triggers the SL BSR and triggers the first SR, the first SR configuration of the terminal equipment for the first SR is the SR configuration corresponding to the SR identifier mapped by the identifier of the logical channel group; the first SR resource configuration of the terminal device for the first SR is one or more SR resource configurations associated with the first SR configuration.

The one or more SR resource configurations are included in a PUCCH configuration in an uplink BWP of a Uu port configured by the base station for the terminal device.

Or optionally, in the embodiment of the present application, if the base station does not configure, for the terminal device, the SR configuration corresponding to the SR identifier mapped by the identifier of the QoS flow included in the second message and the SR resource configuration associated with the SR configuration before, the second message further needs to include the SR configuration corresponding to the SR identifier and one or more SR resource configurations associated with the SR configuration. The one or more SR resource configurations are included in a PUCCH configuration in an uplink BWP of a Uu port configured by the base station for the terminal device.

Optionally, in this embodiment of the present application, if the base station has previously sent, to the terminal device, an SR configuration corresponding to an SR identifier mapped by an identifier of a logical channel of a side uplink radio bearer included in the second message, but for the logical channel of the side uplink radio bearer mapped by the SR identifier, it is necessary to associate a new SR resource configuration with the SR configuration corresponding to the SR identifier, then the second message also needs to include one or more SR resource configurations associated with the SR configuration corresponding to the SR identifier. The one or more SR resource configurations are included in a PUCCH configuration in an uplink BWP of a Uu port configured by the base station for the terminal device.

Alternatively, in the embodiment of the present application, if the base station does not configure, for the terminal device, the SR configuration corresponding to the SR identifier mapped by the identifier of the logical channel of the side uplink radio bearer included in the second message and the SR resource configuration associated with the SR configuration before, the second message further needs to include the SR configuration corresponding to the SR identifier and one or more SR resource configurations associated with the SR configuration.

Alternatively, if the first message includes the source information and the destination information of the V2X service, the second message may also include the source information and the destination information of the V2X service, and the related description may refer to step S502 described above, which is not repeated herein.

In this embodiment of the present application, the identifier (SL DRB ID) of the side uplink radio bearer mapped by the QoS flow is an identifier of the side uplink radio bearer mapped by the QoS flow included in the second message. The identification (Logical channel ID) of the logical channel of the side-link radio bearer to which the QoS flow is mapped is the identification of the logical channel of the side-link radio bearer to which the QoS flow is mapped included in the second message.

Further, if the second message includes a mapping relationship between the identifier of the side uplink radio bearer mapped by the QoS flow and the identifier of the logical channel group to which the logical channel of the side uplink radio bearer mapped by the QoS flow belongs, the terminal device may configure the logical channel group to which the logical channel of the side uplink radio bearer mapped by the QoS flow belongs to be the logical channel group to which the identifier of the side uplink radio bearer mapped by the QoS flow corresponds according to the mapping relationship between the identifier of the side uplink radio bearer mapped by the QoS flow and the identifier of the logical channel group to which the logical channel of the side uplink radio bearer mapped by the QoS flow belongs.

And a second case: the first identifier is a QoS index for indicating QoS information.

Taking V2X service AS an example, when an upper layer (application layer, or V2X layer) of the terminal device delivers a V2X service packet to the AS, the AS layer is informed of QoS index of QoS information of the V2X service or the V2X service packet to be transmitted. The QoS index may be, for example, a 5G QoS identifier (5G QoS identifier,5QI), a V2X/vehicle-to-vehicle (vehicle to vehicle, V2V) QoS Identifier (VQI), a QoS class identifier (QoS class identifier, QCI), or other form of index value. Wherein each QoS index value corresponds to a set of QoS information.

Optionally, when the upper layer of the terminal device submits the V2X service packet to the AS, the AS layer is informed of whether the transmission mode adopted by the V2X service packet is unicast transmission, multicast transmission or broadcast transmission. Or when the upper layer of the terminal equipment informs the AS layer of the QoS index and the QoS information indicated by the QoS index, the AS layer is informed of whether the transmission mode adopted by the V2X service packet corresponding to the QoS index is unicast transmission, multicast transmission or broadcast transmission.

Further, the AS layer of the terminal device triggers the first message and requests resources for V2X side uplink communication from the base station through the first message. The first message includes a first identifier, where the first identifier is a QoS index of QoS information of a V2X service or a V2X service packet to be transmitted by the terminal device.

After receiving the first message from the terminal device, the base station corresponds to several different processing mechanisms as follows.

Sub-case e: the second identity is an identity of the logical channel group.

After receiving the first message from the terminal equipment, the base station determines a logic channel group mapped by the QoS index in the first message, and determines the SR related configuration mapped by the logic channel group according to the QoS information corresponding to or indicated by the QoS index. Further, the base station transmits a second message to the terminal device, wherein the second message includes the identifier of the logical channel group mapped by the QoS index and the SR identifier mapped by the identifier of the logical channel group.

Alternatively, in the embodiment of the present application, different QoS indexes may correspond to the same or different logical channel groups, and SR identifiers mapped by the identifiers of the different logical channel groups may be the same or different. The mapping relationship of QoS index, logical channel group identity and SR identity may be shown in table three, for example.

The one or more SR resource configurations are included in a PUCCH configuration in an uplink BWP of a Uu port configured by the base station for the terminal device.

After receiving the second message from the base station, the terminal device establishes the side uplink radio bearer to which the QoS index is mapped. The relevant description may refer to the description of the side uplink radio bearer mapped by the QoS flow established in the above sub-case a, and will not be repeated here. The mapping relationship between the QoS index and the side uplink radio bearer may be one-to-one mapping or many-to-one mapping.

Taking V2X service as an example, when the terminal device has V2X service to be transmitted, an upper layer (application layer, or V2X layer) of the terminal device has two processing modes for the V2X service.

One possible way of handling is: the upper layer of the terminal device maps the V2X service to one or more QoS flows, and informs the AS layer of the identification of each QoS flow and the QoS information corresponding to the QoS flow. When the upper layer of the terminal device delivers the V2X service packet to the AS, the AS layer is informed of the QoS flow identifier to which the V2X service packet belongs.

Another possible processing method is: the upper layers of the terminal device do not map V2X traffic to one or more QoS flows.

Further, if the second message includes a mapping relationship between the identifier of the side uplink radio bearer and the identifier of the logical channel group to which the logical channel of the side uplink radio bearer belongs, the terminal device may configure, according to the mapping relationship between the identifier of the side uplink radio bearer and the identifier of the logical channel group to which the logical channel of the side uplink radio bearer belongs, the logical channel group to which the logical channel of the side uplink radio bearer belongs to be the logical channel group to which the identifier of the side uplink radio bearer corresponds.

If the logical channel of the side uplink radio bearer triggers the SL BSR and triggers a third SR, the third SR configuration of the terminal equipment for the third SR is configured as the SR configuration corresponding to the SR identifier mapped by the identifier of the logical channel of the side uplink radio bearer; the SR resource configuration for the third SR by the terminal device is one or more SR resource configurations associated with the third SR configuration.

Based on the above configuration method provided by the embodiment of the present application, the configuration for SR configuration and SR resource configuration used when the Uu port of the NR system transmits the SR for the side uplink data transmission of the PC5 port can be realized.

Alternatively, in the above embodiment, the SR-related configuration for the V2X service may be the same as or different from the SR-related configuration for the uplink data transmission of the Uu port of the terminal device.

Alternatively, the above embodiments may be used in combination. For example, for the V2X service or the V2X service packet of unicast transmission, the method described in the embodiment corresponding to the case 1 may be adopted, and for the V2X service or the V2X service packet of multicast transmission or broadcast transmission, the method described in the embodiment corresponding to the case 2 may be adopted, which is herein collectively described, and the embodiment of the present application is not limited specifically.
