Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a side link configuration method, network-side equipment, terminal, and medium. Background Technology

[0002] Sidelink relay (SL RELAY) refers to a technology where a terminal establishes a PC5 connection with another terminal, using that terminal as a relay to access the access network. In SL RELAY, multiple remote UEs can connect to a single relay UE.

[0003] For Layer 2 side-link relays, the QoS requirements of each remote UE's QoS flow are jointly guaranteed by the PC5 link between the relay UE and the remote UE and the UU link between the relay UE and the access network. The access network will split the QoS requirements of the remote UE's QoS flow on the PC5 and UU links.

[0004] Both the PC5 link and the relay UE's UU link are wireless links, which are affected by terminal mobility. For example, due to the mobility of the remote UE and the relay UE, the transmission performance of the PC5 link and the relay UE's UU link will be affected, and the current QoS allocation scheme cannot meet the transmission requirements.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0060] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0061] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0062] First Embodiment

[0063] like Figure 1 As shown, an embodiment of the present invention provides a side-link configuration method applied to a network-side device. This method includes, but is not limited to, the following steps:

[0064] Step 11: Receive measurement information for the sidelink wireless link.

[0065] Among them, the side-link wireless links include: PC5 links between remote terminals, PC5 links between remote terminals (remote UE) and relay terminals (relay UE), or UU links between relay terminals and network-side devices.

[0066] Step 12: Based on the measurement information, send a reconfiguration message for the sidelink wireless link.

[0067] Specifically, the network-side device can trigger the sending of a reconfiguration message for the sidelink wireless link after receiving measurement information, or it can trigger the sending of a reconfiguration message for the sidelink wireless link only after receiving measurement information and determining that the sidelink wireless link has changed. This allows for flexible configuration of the sidelink wireless link by reconfiguring it to meet its transmission performance requirements and avoids the impact on sidelink transmission performance caused by the mobility of terminals within the sidelink.

[0068] Optionally, the reconfiguration message includes at least one of the following configuration information:

[0069] The first mapping information from the remote terminal's UU interface packet data aggregation protocol PDCP to the PC5 interface radio link layer control protocol RLC;

[0070] The second mapping information from the PC5 interface RLC channel of the relay terminal to the uu interface RLC channel;

[0071] Combined identifier information, which is a combination of the first mapping information and the second mapping information.

[0072] In other words, the reconfiguration message contains: mapping information from uu PDCP to PC-RLC for one or more remote UEs, and / or mapping information from PC5 RLC channels to uu RLC channels for one or more relays.

[0073] Optionally, the reconfiguration message may include a combination of identifier information indicating the mapping information from uu PDCP to PC-RLC of one or more remote UEs and / or the mapping information from PC5 RLC channels to uu RLC channels of one or more relays.

[0074] Furthermore, when the reconfiguration message includes the first mapping information, it also includes reconfiguration information for the PC5 interface adaptation layer. In other words, if the reconfiguration message contains mapping information from the remote UE's uu PDCP to PC-RLC, then it needs to include reconfiguration information for the PC5 adaptation layer.

[0075] Optionally, when the reconfiguration message includes the second mapping information, the reconfiguration message also includes reconfiguration information for the UU interface adaptation layer. That is, if the reconfiguration message contains mapping information from the relay's PC5 RLC channel to the UU RLC channel, then it needs to include reconfiguration information for the air interface adaptation layer.

[0076] Optionally, after step 12, the method further includes: receiving feedback information from the relay terminal, the feedback information being used to indicate the configuration information selected by the relay terminal in the reconfiguration message; and sending reconfiguration confirmation information.

[0077] Specifically, the Relay UE feeds back the mapping information from the uu PDCP to the PC-RLC and / or the mapping information from the relay's PC5 RLC channel to the uu RLC channel to the network; if the reconfiguration message sent by the network contains combined identification information, then the combined identification information is fed back.

[0078] In this embodiment of the invention, the network-side device reconfigures the wireless link of the side link through the reconfiguration message of the side link. In this way, when the measurement information of the side link changes, the side link can be flexibly configured to meet the transmission performance requirements of the side link and avoid the impact of the side link transmission performance caused by the mobility of the terminal in the side link.

[0079] The above describes the side link configuration method from the perspective of network-side devices. The following section will further explain the side link configuration method for terminals with reference to the attached diagram.

[0080] like Figure 2 As shown, this embodiment of the invention provides a side-link configuration method applied to a terminal, wherein the terminal may be a relay terminal. The side-link configuration method includes, but is not limited to, the following steps:

[0081] Step 21: Send measurement information for the sidelink wireless link.

[0082] Among them, the side-link wireless links include: PC5 links between remote terminals, PC5 links between remote terminals and relay terminals, or UU links between relay terminals and network-side devices.

[0083] Step 22: Receive the reconfiguration message for the sidelink wireless link.

[0084] The reconfiguration message includes at least one of the following configuration information:

[0085] The first mapping information from the remote terminal's UU interface packet data aggregation protocol PDCP to the PC5 interface radio link layer control protocol RLC;

[0086] The second mapping information from the PC5 interface RLC channel of the relay terminal to the uu interface RLC channel;

[0087] Combined identifier information, which is a combination of the first mapping information and the second mapping information.

[0088] Optionally, after step 22, the method further includes: selecting configuration information in the reconfiguration message, the configuration information including: mapping information from the remote terminal's UU interface Packet Data Convergence Protocol (PDCP) to the PC5 interface Radio Link Layer Control Protocol (RLC), and / or, mapping information from the relay terminal's PC5 interface RLC channel to the UU interface RLC channel, and / or, combination identifier information of the combination of the first mapping information and the second mapping information. That is, the relay UE terminal selects one type of reconfiguration information or a combination of reconfiguration information from the network reconfiguration message to reconfigure the remote UE's UU PDCP to PC-RLC mapping information and / or the relay's PC5 RLC channel to the UU RLC channel mapping information.

[0089] Furthermore, after selecting configuration information in the reconfiguration message, the process also includes: sending feedback information to the network-side device, which indicates the configuration information selected by the relay terminal in the reconfiguration message; and receiving reconfiguration confirmation information sent by the network-side device. Specifically, the Relay UE feeds back the mapping information from the uu PDCP to the PC-RLC and / or the mapping information from the relay's PC5 RLC channel to the uu RLC channel to the network; if the reconfiguration message sent by the network contains combined identifier information, then the combined identifier information is fed back.

[0090] Taking remote UE movement as an example, the PC5 link signal quality degrades after the remote UE moves. The terminal reports measurement information to the network-side equipment, and the network-side equipment sends multiple QoS configuration schemes. These QoS configuration schemes may include remapping the remote UE's uu PDCP to PC5 RLC, with the remapping including the Data Radio Bearer ID (DRB ID) and PC5 RLC indication information; or remapping the relay UE's PC5 RLC to UU RLC, with the remapping including PC5 RLC indication information and LCID (unique indicator of UU RLC); or a QoS configuration scheme may include both types of mapping.

[0091] The terminal receives QoS configuration scheme information, selects one of them, and feeds back to the network-side device, or feeds back the scheme indication information to the network-side device.

[0092] In this embodiment of the invention, the terminal receives a reconfiguration message for the side link wireless link sent by the network-side device and reconfigures the side link wireless link. In this way, when the measurement information of the side link wireless link changes, the side link wireless link can be flexibly configured to meet the transmission performance requirements of the side link wireless link, and the transmission performance of the side link can be avoided due to the mobility of the terminal in the side link.

[0093] Second Embodiment

[0094] like Figure 3 As shown, an embodiment of the present invention provides a side-link configuration method applied to a network-side device. This method includes, but is not limited to, the following steps:

[0095] Step 31: Receive a reconfiguration request message from the relay terminal.

[0096] The reconfiguration request message can be sent by the relay terminal after the measurement information of the side link wireless link changes, or it can be sent periodically by the relay terminal.

[0097] Step 32: Based on the reconfiguration request message, send a reconfiguration message for the side link wireless link.

[0098] The reconfiguration message includes at least one of the following: first mapping information from the remote terminal's UU interface Packet Data Convergence Protocol (PDCP) to the PC5 interface Radio Link Layer Control Protocol (RLC); second mapping information from the relay terminal's PC5 interface RLC channel to the UU interface RLC channel; and a combination identifier information for the combination of the first and second mapping information. Optionally, the network-side device can determine the reconfiguration message based on the information carried in the reconfiguration request message. For example, the mapping information from UU PDCP to PC-RLC and / or the mapping information from the relay's PC5 RLC channel to the UU RLC channel; if the reconfiguration message sent by the relay UE contains combination identifier information, then the message contains combination identifier information.

[0099] The reconfiguration request message includes at least one of the following:

[0100] The first mapping information from the remote terminal's UU interface packet data aggregation protocol PDCP to the PC5 interface radio link layer control protocol RLC;

[0101] The second mapping information from the PC5 interface RLC channel of the relay terminal to the uu interface RLC channel;

[0102] Combined identifier information, which is a combination of the first mapping information and the second mapping information.

[0103] For example, the reconfiguration request message may contain mapping information from uu PDCP to PC-RLC for one or more remote UEs, and / or mapping information from PC5 RLC channels to uu RLC channels for one or more relays.

[0104] Alternatively, the reconfiguration request message may contain a combination of identifier information indicating the mapping information from uu PDCP to PC-RLC of one or more remote UEs and / or the mapping information from PC5 RLC channels to uu RLC channels of one or more relays.

[0105] Furthermore, when the reconfiguration request message includes combined identification information, the reconfiguration message includes: combined identification information configured by the network-side device.

[0106] Optionally, if the reconfiguration request message contains mapping information from uu PDCP to PC-RLC for the remote UE, then the reconfiguration message needs to include reconfiguration information for the PC5 interface adaptation layer; if the reconfiguration request message contains mapping information from the PC5 RLC channel to the uu RLC channel for the relay, then the reconfiguration message needs to include reconfiguration information for the air interface adaptation layer.

[0107] Optionally, when the information corresponding to the combined identification information includes the mapping information from the remote terminal's uu interface PDCP to the PC5 interface RLC, the reconfiguration message includes the reconfiguration information of the PC5 interface adaptation layer. That is, if the reconfiguration request message contains combined identification information, and the configuration information corresponding to that combined identification information contains the mapping information from the remote UE's uu PDCP to the PC-RLC, then the reconfiguration message needs to include the reconfiguration information of the PC5 adaptation layer.

[0108] Optionally, if the information corresponding to the combined identifier includes mapping information from the PC5 interface RLC channel of the relay terminal to the uu interface RLC channel, the reconfiguration message includes reconfiguration information for the uu interface adaptation layer. In other words, if the reconfiguration request message contains combined identifier information, and the configuration information corresponding to that combined identifier includes mapping information from the relay's PC5 RLC channel to the uuRLC channel, then the reconfiguration message needs to include reconfiguration information for the air interface adaptation layer.

[0109] Optionally, after step 32, the method further includes: receiving reconfiguration completion information sent by the relay terminal. That is, after the relay terminal receives the reconfiguration message sent by the network-side device, it reconfigures the sidelink wireless link and sends back reconfiguration completion information.

[0110] In this embodiment of the invention, the terminal sends a reconfiguration request message to the network-side device, and the network-side device sends a reconfiguration message to the terminal based on the reconfiguration request message to reconfigure the wireless link of the side link. In this way, when the measurement information of the side link changes, the side link can be flexibly configured to meet the transmission performance requirements of the side link and avoid the impact of the side link transmission performance caused by the mobility of the terminal in the side link.

[0111] The above describes the side link configuration method from the perspective of network-side devices. The following section will further explain the side link configuration method for terminals with reference to the attached diagram.

[0112] like Figure 4 As shown, this embodiment of the invention provides a sidelink configuration method applied to a terminal, which can be a relay terminal. The method includes, but is not limited to:

[0113] Step 41: Send a reconfiguration request message.

[0114] The relay terminal can be triggered by changes in PC5 and UU measurement information or by periodic triggering, and the Relay UE will report a reconfiguration request message to the network. For example, step 41 may include:

[0115] When the measurement information of the side link wireless link changes, a reconfiguration request message is sent. The side link wireless link includes: PC5 link between remote terminals, PC5 link between remote terminal and relay terminal, or uu link between relay terminal and network side device.

[0116] or,

[0117] Periodically send reconfiguration request messages.

[0118] Step 42: Receive the reconfiguration message for the sidelink wireless link.

[0119] The configuration parameters carried in this reconfiguration message can be the same as or different from those carried in the reconfiguration request message.

[0120] The reconfiguration request message includes at least one of the following:

[0121] The first mapping information from the remote terminal's UU interface packet data aggregation protocol PDCP to the PC5 interface radio link layer control protocol RLC;

[0122] The second mapping information from the PC5 interface RLC channel of the relay terminal to the uu interface RLC channel;

[0123] Combined identifier information, which is a combination of the first mapping information and the second mapping information.

[0124] For example, the reconfiguration request message may contain mapping information from uu PDCP to PC-RLC for one or more remote UEs, and / or mapping information from PC5 RLC channels to uu RLC channels for one or more relays.

[0125] Alternatively, the reconfiguration request message may contain a combination of identifier information indicating the mapping information from uu PDCP to PC-RLC of one or more remote UEs and / or the mapping information from PC5 RLC channels to uu RLC channels of one or more relays.

[0126] The reconfiguration message may include mapping information from uu PDCP to PC-RLC, and / or mapping information from the relay's PC5 RLC channel to the uu RLC channel. If the reconfiguration message sent by the relay UE contains combined identifier information, then the message includes combined identifier information.

[0127] Optionally, if the reconfiguration message contains mapping information from uu PDCP to PC-RLC for the remote UE, then reconfiguration information for the PC5 adaptation layer is required; if the reconfiguration message contains mapping information from the PC5 RLC channel to the uu RLC channel for the relay, then reconfiguration information for the air interface adaptation layer is required; if the reconfiguration message contains combined identifier information, and the configuration information corresponding to the combined identifier information contains mapping information from uu PDCP to PC-RLC for the remote UE, then reconfiguration information for the PC5 adaptation layer is required; if the reconfiguration message contains combined identifier information, and the configuration information corresponding to the combined identifier information contains mapping information from the PC5 RLC channel to the uu RLC channel for the relay, then reconfiguration information for the air interface adaptation layer is required.

[0128] The process after step 42 also includes sending a reconfiguration completion message to inform the network-side device that the reconfiguration is complete.

[0129] The following example uses the movement of a remote terminal. After the remote UE moves, the signal quality of the PC5 link degrades. The terminal reports multiple QoS configuration schemes to the network-side equipment. These QoS configuration schemes may include remapping the remote UE's uu PDCP to PC5 RLC, with the remapping including the Data Radio Bearer ID (DRB ID) and PC5 RLC indication information; QoS configuration schemes may include remapping the relay UE's PC5 RLC to UU RLC, with the remapping including PC5 RLC indication information and LCID (unique indicator of UU RLC); QoS configuration schemes may include both of these mappings simultaneously.

[0130] The network-side device receives the QoS configuration scheme information sent by the terminal and selects one of them. The network-side device sends configuration selection information to the terminal, or sends the scheme indication information to the terminal. The terminal receives the configuration selection information sent by the network-side device. After successful reception, the terminal sends QoS reconfiguration completion information to the network-side device.

[0131] In this embodiment of the invention, the terminal sends a reconfiguration request message to the network-side device, and the network-side device sends a reconfiguration message to the terminal based on the reconfiguration request message to reconfigure the wireless link of the side link. In this way, when the measurement information of the side link changes, the side link can be flexibly configured to meet the transmission performance requirements of the side link and avoid the impact of the side link transmission performance caused by the mobility of the terminal in the side link.
