Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for configuring a sidelink radio bearer.
Background
V2X (Vehicle to X, information exchange between Vehicle and outside world) is a key technology of future intelligent transportation systems, and mainly studies Vehicle data transmission schemes based on The 3rd Generation Partnership Project (3 GPP) communication protocol. V2X communication includes V2V communication (Vehicle to Vehicle communication), V2I communication (Vehicle to Infrastructure communication), and V2P communication (Vehicle to pedestrian communication). The application of V2X will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and vehicle-mounted entertainment information, etc.
Before performing the V2X Sidelink communication, a terminal (User Equipment, UE) needs to configure a Sidelink Radio Bearers (SLRB) corresponding to the service characteristic parameters. The Service characteristic parameter may include Quality of Service (QoS) information. In the LTE system, QoS of a UE Packet is guaranteed by PPPP (ProSe Per Packet Priority) and PPPR (ProSe Per Packet Reliability). For each data packet, the PPPP and PPPR are determined by the application layer, the PPPP and PPPR may each be an integer from 1 to 8, the higher the number, the lower the priority and reliability requirements, and the PPPP and PPPR of the data packet are set when the application layer delivers the data packet to the underlying layer for transmission. And the mapping of the data packet to the SLRB is finished by the terminal, and the specific mapping rule is determined by the terminal.
In the 5G system, the QoS of the terminal packet is based on a QoS flow mechanism with a Guaranteed Bit Rate (GBR) or a non-guaranteed bit rate (non-GBR), and an SDAP (Service Data Adaptation Protocol) layer is introduced for completing the mapping of the QoS flow to the SLRB. The QoS flow is identified by a QoS flow Identification number (QFI) and is mapped to a SLRB of an Access Stratum (AS). One or more QoS flows may be mapped to the same SLRB, but one QoS flow may be mapped to only one SLRB. The QoS characteristics of the data packets on the same QoS flow are the same, the base station broadcasts the SLRB configuration information corresponding to the QoS through the broadcast shape, and the mapping of the QoS and the QoS flow is completed by the terminal.
Before transmitting a packet between terminals, it is necessary to allocate an SLRB corresponding to QoS, and the base station broadcasts SLRB allocation information corresponding to QoS to the terminals via a specific system information block. However, this occupies more system resources, and in the fifth generation communication system (5G) and future communication systems, there is no complete solution for how the terminal configures the SLRB when the system information block does not have SLRB configuration information corresponding to QoS broadcast.

The embodiment of the application defines a terminal-to-terminal communication link as a side link.
It should be understood that the term "and/or" herein is merely one type of association relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document indicates that the former and latter related objects are in an "or" relationship.
The "plurality" appearing in the embodiments of the present application means two or more.
The term "connect" in the embodiments of the present application refers to various connection manners, such as direct connection or indirect connection, to implement communication between devices, which is not limited in this embodiment of the present application.
In the embodiments of the present application, "network" and "system" represent the same concept, and a communication system is a communication network.
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for configuring an SLRB according to an embodiment of the present invention. The configuration method is applicable to the terminal side.
In S11, a sidelink radio bearer configuration indication sent by the base station is received, where the sidelink radio bearer configuration indication is adapted to indicate a manner of obtaining sidelink radio bearer configuration information corresponding to the service characteristic parameter.
In S12, the sidelink radio bearer configuration information corresponding to the service characteristic parameter is obtained according to the sidelink radio bearer configuration instruction.
In some embodiments, the traffic characteristic parameter may be selected from: the index value of the service attribute, the QoS stream identifier, the QoS parameter set, the QoS parameter identifier, and the QoS parameter set identifier are not limited in the present invention.
The QoS parameter may include priority of a service, Packet Delay Budget (PDB), Packet Error Rate (PER), Maximum Data Burst Volume (MDBV), Guaranteed Bit Rate (GBR), Maximum Bit Rate (MBR), Aggregated Maximum Bit Rate (AMBR), jitter (jitter) Packet Delay Budget, and Packet Error Rate (bler).
In the prior art, the terminal receives the SLRB configuration information in a specific first system information block. It is noted that in the NR side link scenario, the SLRB configuration information is very complex, including numerous parameters. Specifically, the SLRB configuration information includes, in addition to the SLRB Identity (ID) and QFI, parameters of a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer, which need to be configured, and includes a discard timer used to calculate when a Packet can be discarded, a PDCP sequence number size indicating the length of a sequence number, and a PDCP sequence number size. The SLRB configuration parameters of the RLC layer include a logical channel ID, an RLC mode. The MAC layer SLRB configuration parameters include a scheduling request ID and the like. In addition, different SLRB configuration information may be configured for different terminals.
In summary, the SLRB configuration process is very complicated, and the base station broadcasting these SLRB configuration parameters in a specific system information block (first system information block) occupies many system resources. In the embodiment of the present invention, the terminal acquires the SLRB configuration indication in the first system information block. That is, the base station does not directly transmit the SLRB configuration information in a specific system information block, but transmits the SLRB configuration indication first, thereby saving system resources of the first system information block.
In some embodiments, the manner of acquiring the SLRB configuration information includes: if the mobile terminal is not in the RRC connection state, entering the RRC connection state; sending a configuration information acquisition request to a base station; and acquiring the SLRB configuration information through high-layer signaling.
Specifically, the base station may instruct the terminal to enter an RRC connected state in the SLRB configuration indication to acquire the SLRB configuration information. At this time, the terminal first determines whether itself is in a connected state, and if itself is in an RRC idle state or a non-connected state, the terminal first performs an RRC connection with the base station to enter an RRC connected state.
And after the terminal enters an RRC connection state, sending a configuration information acquisition request to the base station. In some embodiments, the terminal may send the configuration information acquisition request to the base station through higher layer signaling. Thereafter, the terminal may acquire the SLRB configuration information transmitted by the base station through higher layer signaling. The higher layer signaling may be RRC signaling.
By establishing RRC connection with the base station, different terminals can obtain different SLRB configuration information according to actual conditions, and the communication quality is improved.
In some embodiments, after acquiring the SLRB configuration information, the terminal maintains an RRC connected state to facilitate a PDU session with other terminals.
In some embodiments, after obtaining the sidelink rb configuration information, the terminal switches to the idle/unconnected state to save power consumption.
In some embodiments, the manner of acquiring the SLRB configuration information includes: and acquiring the SLRB configuration information in a second system information block. In this embodiment, after the terminal acquires the SLRB configuration information by the SLRB configuration instruction, the terminal directly receives the SLRB configuration information in the second system information block.
The base station may broadcast the SLRB configuration information through a second system information block different from the first system information block. Each terminal in the cell receives the same SLRB configuration information. Since the base station transmits the SLRB configuration information in the new second system information block, system resources transmitted in the first system information block are saved.
In addition, the present embodiment can reduce system overhead compared to the embodiment in which the SLRB configuration information is acquired through the RRC connection.
In some embodiments, the manner of acquiring the SLRB configuration information includes: sending a configuration information acquisition request to a base station; and acquiring the SLRB configuration information within a second system information block. In this embodiment, after the terminal acquires the SLRB configuration information through the SLRB configuration instruction, the terminal may first send a configuration information acquisition request to the base station through a Random Access Channel (RACH), and if there is corresponding SLRB configuration information, the terminal does not need to send the configuration information. If the base station does not receive any configuration information acquisition request, the SLRB configuration information can not be sent, so that the system overhead is reduced.
In some embodiments, the manner of acquiring the SLRB configuration information includes: the pre-configuration information is adopted as the SLRB configuration information. Specifically, the terminal is provided with preconfigured information about the SLRB configuration information, which may be specified by a protocol or set by each manufacturer. Therefore, the terminal does not need to acquire the side link radio bearer configuration information through the base station, and the system overhead is further reduced.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for configuring an SLRB according to an embodiment of the present invention. The configuration method is suitable for a base station side, and the base station side is configured with side link radio bearer configuration information and a plurality of modes of acquiring the side link radio bearer configuration information by a terminal.
In S21, one of the multiple ways for the terminal to obtain the sidelink rb configuration information corresponding to the service characteristic parameter is selected.
In S22, a sidelink radio bearer configuration indication is broadcasted, where the sidelink radio bearer configuration indication is adapted to indicate a manner in which the selected terminal obtains the sidelink radio bearer configuration information corresponding to the service characteristic parameter.
In some embodiments, the traffic characteristic parameter may be selected from: the index value of the service attribute, the QoS stream identifier, the QoS parameter set, the QoS parameter identifier, and the QoS parameter set identifier are not limited in the present invention. For the detailed description of the QoS parameters, reference may be made to the above description, which is not repeated herein.

In some embodiments, the SLRB configuration indication comprises: and indicating the terminal to acquire the SLRB configuration information through high-level signaling.
In some embodiments, the configuration method further comprises: receiving a configuration information acquisition request sent by a terminal; and sending the SLRB configuration information through high-layer signaling.

In some embodiments, the configuration method further comprises: and sending the SLRB configuration information in a second system information block.
In some embodiments, the configuration method further comprises: receiving a configuration information acquisition request sent by a terminal; and transmitting the SLRB configuration information in a second system information block.
In some embodiments, the SLRB configuration indication comprises: and indicating the terminal to adopt the pre-configuration information as the SLRB configuration information.
For more details about the configuration method of the base station side, reference may be made to the above description of the configuration method of the terminal side, and details are not described here again.
In some embodiments, when the terminal fails to acquire the SLRB configuration information corresponding to a certain service feature parameter for various reasons, the terminal may directly acquire the SLRB configuration information corresponding to the service feature parameter by using the method for acquiring the SLRB configuration information in the configuration method.
For example, when the terminal does not acquire the SLRB configuration information corresponding to a certain service characteristic parameter, the terminal enters an RRC connected state and transmits a configuration information acquisition request to the base station. The base station receives the configuration information acquisition request, and can send the SLRB configuration information to the terminal through a high-level signaling, that is, the terminal can acquire the SLRB configuration information corresponding to the service characteristic parameter through the high-level signaling. After acquiring the sidelink rb configuration information, the terminal may remain in the RRC connected state or may switch to the idle/non-connected state.
For another example, when the terminal does not acquire the SLRB configuration information corresponding to a certain service characteristic parameter, the terminal transmits a configuration information acquisition request to the base station. After receiving the configuration information acquisition request, the base station may send the SLRB configuration information to the terminal through the new system information block, that is, the terminal may acquire the SLRB configuration information corresponding to the service feature parameter through the new system information block.
For another example, when the terminal does not acquire the SLRB configuration information corresponding to a certain service characteristic parameter, the pre-configuration information may be directly employed as the SLRB configuration information.
