Description

Transmission configuration method and terminal for direct link radio bearer
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a terminal for configuring transmission of a direct link radio bearer.
Background
Vehicle-to-outside information exchange (V2X) technology can sense the surrounding conditions of vehicles in real time, share road information and perform early warning in time by means of wireless communication between vehicles, vehicle-to-vehicle infrastructure, and vehicles and passersby, and has become a research hotspot for solving the problem of road safety in countries in the world at present.
For unicast communication of the direct communication interface, a Radio bearer between two terminals in direct communication allows the use of Radio Link Control (RLC) Acknowledged Mode (AM) and Unacknowledged Mode (UM). Both RLC AM and UM modes support bidirectional direct link radio Bearer (SLRB), and according to the existing NR V2X technology, the Logical Channel Identity (LCID) and RLC Mode in the SLRB corresponding to both directions need to be the same. However, for direct communication, if the coverage conditions of two terminals are different (e.g., one is on-network, one is off-network, or both are on-network but in different base station coverage areas) or Radio Resource Control (RRC) states are different (e.g., one is in connected state and one is in IDLE state), it may cause collision of LCID and/or RLC Mode in both directions of the bidirectional SLRB.
Furthermore, for NR V2X, in order to improve transmission reliability, a duplicate transmission mechanism needs to be introduced. For example, in NR, repeated transmission (PDCP repetition) may support at most 4 channels (legs) for repeated transmission, that is, one PDCP entity corresponds to 4 RLC entities, and repeated PDCP data packets are transmitted through 4 logical channels respectively.
However, after introducing the retransmission mechanism, each repeatedly transmitted channel (leg) has its own LCID, and at this time, for the RLC bidirectional radio bearer, how to solve the LCID and/or RLC mode collision problem needs further research.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Specifically, in the existing NRV2X technology, the LCID is allocated by the terminal itself, and multiple legs are supported during transmission, each leg has its own LCID, and for the RLC AM/UM Mode, a bidirectional SLRB may be supported, which may cause collision of the LCID and/or RLC Mode in both directions of the bidirectional SLRB. For example, if a bidirectional SLRB is configured, terminal 1 and terminal 2 establish SLRB-to-LCID 1 of a unicast RLC AM of a direct communication interface, and terminal 1 may use LCID1 when transmitting to terminal 2, and terminal 2 may also use LCID1 when transmitting to terminal 1, that is, terminal 1 transmits to terminal 2 and terminal 2 transmits to terminal 1 using the same LCID and both are RLC AM, that is, RLC Mode collision of the same LCID does not occur; however, if terminal 1 configures bidirectional SLRB, RLC AM Mode, LCID1, and terminal 2 configures RLC UM Mode, LCID1, then the problem of RLC Mode collision of the same LCID occurs in the communication between terminal 1 and terminal 2, and the SLRB establishment is considered to be failed.
Aiming at the problem that the collision of LCID and RLC Mode of the bidirectional SLRB in the repeated transmission is not considered in the prior art, the invention provides the following embodiment to solve the problem of the collision of LCID and RLC Mode of the bidirectional SLRB in the repeated transmission and ensure the normal transmission of the SLRB.
Specifically, as shown in fig. 1, it is a flowchart of a step of an SLRB transmission configuration method applied to a first terminal in an embodiment of the present invention, where the method includes the following steps:
step 101: and receiving the SLRB repeated transmission message sent by the second terminal.
In this step, specifically, the SLRB repeat transmission message includes LCID information of SLRB configuration or activation leg and RLC Mode information corresponding to the SLRB.
Specifically, the RLC Mode may be AM, UM or Transparent Mode (TM).
For example, if SLRB configures leg1 and leg2, and the RLC Mode corresponding to SLRB is RLC AM, the SLRB repeat transmission message may include LCID information of leg1 and leg2, and the RLC Mode including SLRB is RLC AM.
In addition, it should be noted herein that the SLRB repeat transmission message may be SLRB repeat transmission configuration information or SLRB repeat transmission activation information.
Specifically, the first terminal can know the repeat transmission configuration condition of the SLRB by receiving the SLRB repeat transmission message.
Step 102: and determining whether the repeated transmission of the SLRB is configured or activated successfully or not according to the LCID information of the configured or activated leg and the RLC Mode information corresponding to the SLRB.
In this step, specifically, after receiving the SLRB repeat transmission message sent by the second terminal, the first terminal may determine whether the SLRB repeat transmission is successfully configured or activated according to the LCID information of the configured or activated leg and the RLC Mode information corresponding to the SLRB in the SLRB repeat transmission message.
That is, when the second terminal configures LCID information and RLC Mode of the bidirectional SLRB, the configured or activated LCID information of the leg and RLC Mode information corresponding to the SLRB may be sent to the first terminal, so that the first terminal can determine whether the repeated transmission of the SLRB is successfully configured or activated, that is, determine whether LCID and/or RLC Mode collision occurs, based on the configured or activated LCID information of the leg and RLC Mode information corresponding to the SLRB, thereby solving the problem of the existing LCID and/or RLC Mode collision.
Specifically, the SLRB repeat transmission message further includes at least one of the following information: the identification information of the leg, the identification information of the first terminal, the identification information of the second terminal, the identification information of the direct link corresponding to the SLRB, and the identification information of the SLRB.
Of course, if the leg includes a main leg and an auxiliary leg, the information of the main leg and the auxiliary leg may be included to distinguish the main leg from the auxiliary leg; the identification information of the terminal may be a layer 2 identification or a terminal identification, and is not limited herein.
Further, when the first terminal determines whether the repeated transmission of the SLRB is successfully configured or activated according to the LCID information of the configured or activated leg and the RLC Mode information corresponding to the SLRB, it may determine whether the SLRB includes the primary leg and the secondary leg. A specific manner for determining whether the repeated transmission of the SLRB is successfully configured or activated according to the LCID information of the configured or activated leg and the RLC Mode information corresponding to the SLRB when the SLRB includes the primary leg and the secondary leg and when the SLRB does not include the primary leg and the secondary leg is described below.
In the first case: when the SLRB includes the primary leg and the secondary leg, when determining whether the repeated transmission of the SLRB is successfully configured or activated according to the LCID information of the configured or activated leg and the RLC Mode information corresponding to the SLRB, the following method may be included:
first, when the primary leg of the SLRB generates RLC Mode collision of the same LCID, it is determined that the repeated transmission configuration or activation of the SLRB fails.
The RLC Mode conflict of the same LCID is that leg of the SLRB has the same LCID and the RLC Mode is different from that of the first terminal.
Specifically, the bearer may be an SLRB, a logical channel, or a leg, which is not limited herein.
For example, if the second terminal configures a bidirectional SLRB, configures an RLC Mode as RLC AM, and configures an LCID of leg1 as LCID1, and meanwhile, it is assumed that the first terminal configures an RLC Mode as RLC UM, and the bearer is leg, and the LCID of leg1 is also LCID1, it can be seen that leg of the SLRB has the same LCID and the RLC Mode is different from that of the first terminal, that is, the RLC Mode of the same LCID collides.
In addition, specifically, when the primary leg of the SLRB generates RLC Mode collision of the same LCID, it is directly determined that the repeated transmission configuration or activation of the SLRB fails, that is, it is determined that the SLRB is failed to establish, so as to solve the problem of RLC Mode and LCID collision in the bidirectional SLRB.
At this time, specifically, after determining that the repeated transmission configuration or activation of the SLRB fails, it is further required to send a configuration or activation failure message to the second terminal, where the configuration or activation failure message includes at least one of the following information: the method comprises the steps of configuring or activating a failure information identifier, configured or activated LCID information of each leg, identifier information of a first terminal, identifier information of a second terminal, identifier information of a direct link corresponding to an SLRB and identifier information of the SLRB. This enables the second terminal to determine the SLRB that failed to be established through the configuration or activation failure message.
In addition, specifically, when the first terminal is in the connected state, a configuration or activation failure message and/or an SLRB repeat transmission message may be sent to the network side device, so that the network side device determines that the SLRB repeat transmission configuration or activation of the first terminal fails. This enables the network device to know that the first terminal is configured with the SLRB repeat transmission message, but fails in configuration or activation, thereby facilitating scheduling of subsequent network-side devices.
And secondly, when the primary leg of the SLRB does not generate the RLC Mode collision of the same LCID and the secondary leg generates the RLC Mode collision of the same LCID, determining to reselect the LCID of the secondary leg.
In this way, only the secondary leg needs to reselect the LCID of the secondary leg when the RLC Mode conflicts with the same LCID occur, and the primary leg does not have the RLC Mode conflicts with the same LCID, so that transmission can continue through the primary leg.
In addition, specifically, after determining to reselect the LCID of the secondary leg, a first LCID reselection message may be sent to the second terminal, where the first LCID reselection message includes at least one of the following information: the LCID reselection information identification, the LCID to be reselected corresponding to the auxiliary leg, the configured or activated LCID which does not need to be reselected, the identification information of the first terminal, the identification information of the second terminal, the identification information of the through link corresponding to the SLRB and the identification information of the SLRB. This enables the second terminal to reselect the LCID of the secondary leg through the first LCID reselection message to avoid the RLC Mode and LCID collision problem in the bidirectional SLRB.
It should be noted that configured or activated LCIDs that do not require reselection indicate that all of the LCIDs are configured or activated successfully (including the primary leg).
In addition, specifically, after determining to reselect the LCID of the secondary leg, when the first terminal is in a connected state, the first LCID reselection message and/or an SLRB repeat transmission message may be sent to the network side device, so that the network side device determines that the SLRB configuration of the first terminal or the LCID to be reselected exists in the active leg; and/or receiving an SLRB repeated transmission message which is sent again by the second terminal according to the first LCID reselection message; and/or transmitting at least one of the following information to the second terminal through a logical channel having the same LCID as the primary leg: PDCP Status Report (SR), header Compression (ROHC) feedback information, and a packet.
That is, for the first terminal in the connected state, the first LCID reselection message and/or the SLRB repeat transmission message may be sent to the network side device to notify that the network side device is configured with the SLRB repeat transmission message, and the configured or activated LCID needs to be reselected, so that the subsequent network side device performs scheduling.
In addition, it should be noted that, based on that the primary leg does not have RLC Mode collision with the same LCID, the subsequent first terminal may send one or more of PDCP SR, ROHC feedback information, and data information to the second terminal by using a logical channel having the same LCID as that of the primary leg.
In addition, it should be noted that, the subsequent first terminal waits for the SLRB repeat transmission message that is retransmitted by the second terminal according to the first LCID reselection message, where the retransmitted SLRB repeat transmission message includes the reselected LCID, and at this time, the first terminal may determine whether the configuration or the activation is successful again.
Thirdly, when the RLC Mode collision of the same LCID does not occur to all the legs of the SLRB, the repeated transmission configuration or the activation of the SLRB is determined to be successful.
Specifically, when all the legs of the SLRB do not have RLC Mode collision of the same LCID, it may be considered that the repeated transmission configuration or activation of the SLRB is successful, and at this time, all the legs may be used to perform the repeated transmission process of the SLRB without causing LCID and RLC Mode collision problems.
In addition, specifically, after determining that the SLRB repeat transmission configuration or activation is successful, when the first terminal is in a connected state, the network side device may send an SLRB repeat transmission message to enable the network side device to determine that the SLRB repeat transmission configuration or activation of the first terminal is successful. Therefore, the network equipment can know that the first terminal is configured with the SLRB repeated transmission message, and convenience is provided for subsequent network side equipment to schedule.
In addition, specifically, after determining that the repeated transmission configuration or activation of the SLRB is successful, a first configuration or activation success message may be sent to the second terminal, where the first configuration or activation success message includes at least one of the following information: the method comprises the steps of configuring or activating a success information identifier, configured or activated LCID of each leg, identification information of a first terminal, identification information of a second terminal, identification information of a direct link corresponding to an SLRB and identification information of the SLRB; and/or transmitting at least one of the following information to the second terminal through a logical channel having the same LCID as the primary leg: PDCP SR, ROHC feedback information and data packet.
Therefore, when the SLRB comprises the primary leg and the secondary leg, whether the primary leg and the secondary leg have the same LCID (radio link control identity) RLC Mode conflict or not is judged through information in the SLRB repeated transmission message, when the primary leg is detected to have the same LCID RLC Mode conflict, repeated transmission configuration or activation failure of the SLRB is determined, when all legs are detected not to have the same LCID RLC Mode conflict, repeated transmission configuration or activation success of the SLRB is determined, when the primary leg is detected not to have the same LCID RLC Mode conflict and the secondary leg has the same LCID RLC Mode conflict, the LCID of the secondary leg is determined to be reselected, the problem of LCID and RLC Mode conflict can be avoided before the SLRB is repeatedly transmitted, and normal repeated transmission of the SLRB is guaranteed.
In the second case: when the SLRB does not include the primary leg and the secondary leg, when determining whether the repeated transmission of the SLRB is successfully configured or activated according to the LCID information of the configured or activated leg and the RLC Mode information corresponding to the SLRB, the following method may be included:
first, when RLC Mode collision of the same LCID occurs to all legs of the SLRB, it is determined that the repeated transmission configuration or activation of the SLRB fails.
Specifically, for a specific explanation of RLC Mode conflicts with the same LCID, reference may be made to the explanation in the first case, and details are not described herein again.
In addition, when the fact that the RLC Mode collision of the same LCID occurs to all the legs of the SLRB is detected, the repeated transmission configuration or activation failure of the SLRB is determined, namely the SLRB establishment failure is determined, so that the problem of the LCID and the RLC Mode collision can be avoided before the SLRB is repeatedly transmitted.
At this time, specifically, after determining that the repeated transmission configuration or activation of the SLRB fails, a configuration or activation failure message needs to be sent to the second terminal, where the configuration or activation failure message includes at least one of the following information: the method comprises the steps of configuring or activating a failure information identifier, configured or activated LCID information of each leg, identifier information of a first terminal, identifier information of a second terminal, identifier information of a direct link corresponding to an SLRB and identifier information of the SLRB. This enables the second terminal to determine the SLRB that failed to be established through the configuration or activation failure message.
In addition, specifically, when the first terminal is in the connected state, a configuration or activation failure message and/or an SLRB repeat transmission message may be sent to the network side device, so that the network side device determines that the SLRB repeat transmission configuration or activation of the first terminal fails. This enables the network device to know that the first terminal is configured with the SLRB repeat transmission message, but fails in configuration or activation, thereby facilitating scheduling of subsequent network-side devices.
And secondly, when the first leg of the SLRB does not generate the RLC Mode collision of the same LCID and the RLC Mode collision of the same LCID occurs in the second leg, determining to reselect the LCID of the second leg.
The first leg is at least one leg in the legs of the SLRB, and the second leg is at least one leg except the first leg in the legs of the SLRB.
That is, part of the legs do not have RLC Mode collisions with the same LCID in all legs, it may be determined that only LCID of the second leg with RLC Mode collisions with the same LCID is reselected.
Specifically, after determining to reselect the LCID of the second leg, a second LCID reselection message may be sent to the second terminal, where the second LCID reselection message includes at least one of the following information: the LCID reselection information identifier, the LCID to be reselected corresponding to the second leg, the configured or activated LCID which does not need to be reselected, the identifier information of the first terminal, the identifier information of the second terminal, the identifier information of the straight-through link corresponding to the SLRB and the identifier information of the SLRB, so that the second terminal performs LCID reselection according to the second LCID reselection message.
In addition, specifically, after determining to reselect the LCID of the second leg, when the first terminal is in a connected state, the network side device may send a second LCID reselection message and/or an SLRB repeat transmission message, so that the network side device determines that the LCID to be reselected exists in the SLRB configuration of the first terminal or in the activated leg; and/or receiving an SLRB repeated transmission message which is sent again by the second terminal according to the second LCID reselection message; and/or transmitting at least one of the following information to the second terminal through a logical channel having the same LCID as any one of the first legs: PDCP SR, ROHC feedback information, and data packet.
That is, for the first terminal in the connected state, the first LCID reselection message and/or the SLRB repeat transmission message may be sent to the network side device to notify that the network side device is configured with the SLRB repeat transmission message, and the configured or activated LCID needs to be reselected, so that the subsequent network side device performs scheduling.
In addition, it should be noted that, based on the existence of the RLC Mode collision that the first leg does not have the same LCID, the subsequent first terminal may send one or more of the PDCP SR, the ROHC feedback information, and the data information to the second terminal by using the logical channel having the same LCID as any of the first legs.
In addition, it should be noted that, the subsequent first terminal waits for the SLRB repeat transmission message that is retransmitted by the second terminal according to the second LCID reselection message, where the retransmitted SLRB repeat transmission message includes the reselected LCID, and of course, at this time, the first terminal will re-determine whether the configuration or the activation is successful.
Thirdly, when all legs of the SLRB do not generate RLC Mode conflicts with the same LCID, determining the repeated transmission configuration or the successful activation of the SLRB;
in this case, if RLC Mode collision of the same LCID does not occur in all the leg, it is determined that the repeated transmission configuration or activation of the SLRB is successful, that is, at this time, the SLRB can be repeatedly transmitted through the information in the current SLRB repeated transmission message, and LCID and RLC Mode collision does not occur.
Specifically, after determining that the SLRB repeat transmission configuration or activation is successful, it is further required that, when the first terminal is in a connected state, the network side device sends an SLRB repeat transmission message to enable the network side device to determine that the SLRB repeat transmission configuration or activation of the first terminal is successful. Therefore, the network side equipment can know that the first terminal is configured with the SLRB repeated transmission message, and convenience is provided for subsequent network side equipment to carry out scheduling.
In addition, specifically, after determining that the repeated transmission configuration or activation of the SLRB is successful, a second configuration or activation success message needs to be sent to the second terminal, where the second configuration or activation success message includes at least one of the following information: the method comprises the steps of configuring or activating a success information identifier, configured or activated LCID of each leg, identification information of a first terminal, identification information of a second terminal, identification information of a direct link corresponding to an SLRB and identification information of the SLRB; and/or transmitting at least one of the following information to the second terminal through a logical channel having the same LCID as any one of the legs: PDCP SR, ROHC feedback information, and data packet.
Therefore, when the SLRB does not comprise the main leg and the auxiliary leg, whether the leg generates the RLC Mode collision with the same LCID or not is judged through the information in the SLRB repeated transmission message, when the fact that all the legs generate the RLC Mode collision with the same LCID is detected, repeated transmission configuration or activation failure of the SLRB is determined, when the fact that all the legs do not generate the RLC Mode collision with the same LCID is detected, repeated transmission configuration or activation success of the SLRB is determined, when the fact that the first leg does not generate the RLC Mode collision with the same LCID and the second leg generates the RLC Mode collision with the same LCID is detected, the LCID of the second leg is determined to be reselected, the problem of LCID and Mode collision can be avoided before the SLRB is repeatedly transmitted, and normal repeated transmission of the RLC SLRB is guaranteed.
