Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
In order to facilitate understanding of the technical solutions of the embodiments of the present invention, the following respectively explains the mode 3 and the mode 4 in the car networking.
Mode 3: as shown in fig. 1, transmission resources of the in-vehicle terminal are allocated by a base station (e.g., an evolved NodeB (eNB) in LTE or a 5G base station gNB in a New Radio (NR) system), and specifically, the base station issues a control message for indicating Grant (Grant) resources to the in-vehicle terminal through a Downlink (DL); then, the in-vehicle terminal transmits data to the SL according to the resource allocated by the base station. In mode 3, the base station may allocate a resource for single transmission to the in-vehicle terminal, or may allocate a resource for semi-static transmission to the terminal.
Mode 4: as shown in fig. 2, the vehicle-mounted terminal adopts a transmission mode of listening + reservation. The vehicle-mounted terminal acquires an available transmission resource set in the resource pool in an intercepting mode, and randomly selects one resource from the transmission resource set to transmit data. Because the service in the car networking system has a periodic characteristic, the vehicle-mounted terminal usually adopts a semi-static transmission mode, that is, after the vehicle-mounted terminal selects one transmission resource, the resource can be continuously used in a plurality of transmission cycles, so that the probability of resource reselection and resource conflict is reduced. The vehicle-mounted terminal can carry the information of the reserved secondary transmission resource in the control information transmitted at this time, so that other terminals can judge whether the resource is reserved and used by the vehicle-mounted terminal by detecting the control information of the vehicle-mounted terminal, and the aim of reducing resource conflict is fulfilled.
It should be noted that, in LTE-V2X, mode 3 is used to indicate that the transmission resource of the Vehicle-mounted terminal is allocated by the base station, and mode 4 indicates that the transmission resource of the Vehicle-mounted terminal is selected by the terminal, so that a New transmission mode may be defined in a New wireless-Vehicle networking technology (NR-V2X, New Radio-Vehicle-to-event), which is not limited in the present invention.
For the above mode architecture of the car networking, when a terminal performs synchronous transmission on multiple carriers, a first carrier set is usually configured by a higher-level device in the network, where the set includes carriers capable of providing synchronous reference information, and the terminal may select a second carrier set from the first carrier set, where the second carrier set includes carriers for performing multi-carrier synchronous transmission by the terminal, and therefore, the second carrier set may be considered as a subset of the first carrier set, and even the second carrier set may be the same as the first carrier set. Based on the relationship between the two carrier sets, the first carrier set needs to be configured for the terminal, which is also an effect to be achieved by the technical solution of the embodiment of the present invention.
All technical solutions of the embodiments of the present invention are applicable not only to a car networking system but also to other end-to-end communication systems, where the terminal in the embodiments of the present invention may be a vehicle-mounted terminal, a handheld terminal, a Personal Digital Assistant (PDA), a wearable terminal, and the like, and the network in the embodiments of the present invention may be an NR network, an LTE network, and the like.
Referring to fig. 3, a flowchart of a method for configuring a synchronization carrier according to an embodiment of the present invention is shown, where the flowchart may be applied to a terminal in an internet of vehicles V2X architecture, and the method may include:
s301: acquiring a first carrier set based on the configuration information; wherein the first set of carriers includes at least one candidate carrier;
s302: a synchronization carrier is selected from the candidate carriers of the first set of carriers.
In the scheme shown in fig. 3, it should be noted that the synchronization carrier refers to a carrier capable of carrying synchronization information, which may be GNSS-based time synchronization information and/or frequency synchronization information; or the time synchronization information and/or the frequency synchronization information based on the base station; but also time synchronization information and/or frequency synchronization information based on the terminal. The scheme shown in fig. 3 will not be described in detail. The synchronization information may be used to provide time synchronization information and/or frequency synchronization information for other carriers during multicarrier transmission, so as to implement synchronous data transmission of multiple carriers.
For the technical solution shown in fig. 3, in a possible implementation manner, the acquiring the first carrier set based on the configuration information includes:
receiving configuration information sent by network side equipment; wherein the configuration information comprises all carriers that can be supported by a sidelink system;
and analyzing the configuration information, acquiring all carriers which can be supported by the sidelink system from the configuration information, and taking all carriers as the first carrier set.
For this implementation, it should be noted that the network side device may send the configuration information in a broadcast message, an RRC related signaling, or a control channel. Correspondingly, receiving the configuration information sent by the network side device may specifically include: and receiving a broadcast message, RRC related signaling or a control channel which is sent by the network side equipment and carries the configuration information.
For example, the network side device takes a base station as an example, the base station may preferably be an eNB or a gNB, and when the terminal is only in the coverage of the base station but does not access the base station, the base station can only transmit a message to the terminal in the coverage in a broadcast manner, so that the base station can carry the configuration information in a broadcast message to transmit the configuration information to the terminal. In addition, in the process of establishing the RRC connection when the terminal accesses the base station, the base station may also carry the configuration information in the RRC interaction signaling and send the configuration information to the terminal. When the access of the terminal is completed, the configuration information can be transmitted through the control channel.
In addition, the configuration information may also be preconfigured or prestored in the terminal, and based on this, in another possible implementation manner, the acquiring the first carrier set based on the configuration information includes: and acquiring all carriers which can be supported by the sidelink system by analyzing the pre-configured configuration information, and taking all carriers as the first carrier set.
For the two implementation manners, selecting a synchronization carrier from the candidate carriers of the first carrier set specifically includes:
selecting a second carrier set for multi-carrier transmission from all carriers which can be supported by the sidelink system;
and selecting the synchronous carrier from the second carrier set.
It should be noted that, at a certain time, the terminal does not use all carriers that can be supported by the sidelink system for multi-carrier transmission, so that, after the base station transmits all carriers that can be supported by the sidelink system to the terminal, the terminal may determine carriers for multi-carrier transmission from all carriers, and the number of the carriers is usually at least one, so that a second carrier set is formed. It is understood that the second carrier set is a subset of the first carrier set, that is, the carriers in the second carrier set are also necessarily in the first carrier set, so that the second carrier set is the same as the first carrier set when the terminal is capable of performing multi-carrier transmission using all carriers that can be supported by the sidelink system.
Moreover, because the carriers in the second carrier set can all perform multi-carrier data transmission, the terminal may select the synchronization carrier from the carriers according to a set selection policy, for example, select the synchronization carrier from the second carrier set according to the priority level, for example, use the carrier with higher priority level in the second carrier set as the synchronization carrier; it is to be understood that the specific priority determination manner may be based on the priority of the synchronization reference information in the carrier; or the priority of the carrier itself, e.g., the priority of the primary carrier is higher than that of the secondary carrier, etc.; or based on the priority of the service corresponding to each carrier, which is not described in this embodiment.
Taking the carrier set diagram shown in fig. 4 as an example, for example, the maximum number of carriers that can be supported by the network system is 8, which are respectively identified as carrier 1, carrier 2, carrier 3, … …, and carrier 8; then, a higher-level device in the network, such as a base station, may use the set including the 8 carriers as a first carrier set, and send the first carrier set to the terminal through the configuration information, and the terminal may select a second carrier set for multi-carrier transmission in the first carrier set in the configuration information, where the second carrier set includes, for example, carrier 1 and carrier 2, and then the terminal may select a synchronization carrier for synchronization reference from the second carrier set according to the priority level, such as carrier 1 or carrier 2, or when the priority levels of the two carriers are the same, the synchronization carrier is carrier 1 and carrier 2.
For the technical solution shown in fig. 3, in a possible implementation manner, the acquiring the first carrier set based on the configuration information includes:
receiving configuration information sent by network side equipment; the configuration information comprises carriers which can be used by the terminal and meet the preset capability description;
and analyzing the configuration information, acquiring the carrier wave which can be used by the terminal and accords with the preset capability description from the configuration information, and taking the carrier wave which can be used by the terminal and accords with the preset capability description as the first carrier wave set.
For this implementation, it should be noted that the network side device may still send the configuration information in a manner of broadcast message, RRC related signaling, or control channel. For a specific sending process, reference is made to the foregoing implementation manner, which is not described herein again.
In addition, the configuration information may also be preconfigured or prestored in the terminal, and based on this, in another possible implementation manner, the acquiring the first carrier set based on the configuration information includes:
and acquiring the carrier wave which can be used by the terminal and accords with the preset capability description by analyzing the pre-configured configuration information, and taking the carrier wave which can be used by the terminal and accords with the preset capability description as the first carrier wave set.
For the two implementation manners, selecting a synchronization carrier from the candidate carriers of the first carrier set specifically includes:
selecting a second carrier set for carrying out multi-carrier transmission from the carriers which can be used by the terminal and accord with the preset capability description;
and selecting the synchronous carrier from the second carrier set.
For the above two implementation manners, in the implementation process, since the capabilities of the terminals in the same network are different, multi-carrier transmission is implemented between the terminals with different capabilities, it is necessary to use carriers that can be used by both the terminals with different capabilities, and carriers that can be used by terminals with lower capabilities are usually used. For example, in the D2D architecture or the V2X architecture, some terminals can support 3GPP standard release Rel-14 or previous releases, and some terminals can support 3GPP standard release Rel-15; therefore, when a terminal supporting Rel-15 release performs multi-carrier transmission to a terminal supporting Rel-14 release or previous release, it is necessary to use carriers that can be used by the terminal supporting Rel-14 release or previous release, and therefore, the carriers that can be used by the terminal according to the preset capability description include: carriers that can be used by terminals supporting end-to-end communication technologies in 3GPP release 14 and previous releases.
Taking the carrier set diagram shown in fig. 5 as an example, for example, the maximum number of carriers that can be supported by the network system is 8, which are respectively identified as carrier 1, carrier 2, carrier 3, … …, and carrier 8. Carriers that can be used by a terminal supporting the 3GPP protocol Rel-14 release are used as the first carrier set, for example, carrier 1, carrier 2, carrier 3, and carrier 4 are carriers that can be used by a Rel-14 terminal, and then the first carrier set includes carrier 1, carrier 2, carrier 3, and carrier 4. If the terminal in this embodiment is configured to support the 3GPP protocol Rel-15 version, the terminal can combine carriers required for multi-carrier transmission, such as carrier 1, carrier 2, and carrier 5, after receiving the first carrier set through the configuration information. The terminal may detect the synchronization information on the carrier 1 and the carrier 2 in turn, so as to divide the carrier 1 and the carrier 2 into a second carrier set, and select a synchronization carrier from the second carrier set.
Based on the same inventive concept of the foregoing technical solution, referring to fig. 6, a flowchart of a method for configuring a synchronization carrier according to an embodiment of the present invention is shown, where the flowchart may be applied to a network-side device in an internet of vehicles V2X architecture, and the method may include:
s601: sending configuration information to a terminal; wherein the configuration information comprises a first set of carriers; the first carrier set is used for the terminal to select a synchronous carrier.
For the technical solution shown in fig. 6, the configuration information may include all carriers that can be supported by the sidelink system, or carriers that can be used by the terminal according to the preset capability description.
For the technical solution shown in fig. 6, in a possible implementation manner, sending the configuration information to the terminal may include:
and sending the configuration information to the terminal through a broadcast message, RRC related signaling or a control channel.
It can be understood that specific contents of this implementation are referred to the technical solution shown in fig. 3, and are not described herein again.
Based on the configuration information including carriers that can be used by the terminal and that meet the preset capability description, in a possible implementation manner, the method further includes:
and selecting the carriers which can be used by the terminal and accord with the preset capability description from all the carriers which can be supported by the sidelink system based on the set capability description information.
For example, a network side device, such as a base station, may obtain capability description information of terminals in a communication coverage area of the base station during an attach or access process of the terminals, and in order to implement multi-carrier transmission between terminals with different capabilities, the network side device, such as the base station, may select carriers that can be used by the terminals that conform to the preset capability description from all carriers that can be supported by a sidelink system. Generally, the carrier that can be used by the terminal according to the preset capability description refers to a carrier that can be used by a terminal with a lower capability. Preferably, in a specific implementation process of this embodiment, the carriers that can be used by the terminal according to the preset capability description include carriers that can be used by terminals that support the end-to-end communication technology in 3GPP release 14 and previous releases. Therefore, the terminal supporting the 3GPP release 15 and the terminal supporting the 3GPP release 14 and the previous release can carry out multi-carrier transmission.
The terminal selects the synchronous carrier from the candidate carriers of the configuration information, thereby realizing the setting scheme of the synchronous carrier when carrying out multi-carrier transmission in the Internet of vehicles technology.
