Description

Technical Field

[0001] The present invention relates to the technical field of communications.

Background Art

[0002] In Release 17, sidelink relay (SL relay) has been studied, and it includes the scenario of UE-to-Network Relay. In this scenario, a remote UE communicates with a network device through a relay UE. Among them, NR Uu is used for the Uu link of the relay UE, and NR sidelink is used for the PC5 interface between the remote UE and the relay UE. In the scenario of UE-to-Network Relay, the relay UE is also referred to as UE-to-Network relay UE.

[0003] Note that the introduction of the above background art is for clearly and completely explaining the technical solution of the present invention and for facilitating the understanding of those skilled in the art. These technical solutions should not be construed as well-known to those skilled in the art just because they are described in the background art of the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor has discovered the following. That is, in Release 17, a remote UE can communicate with a network device by means of relay, or a remote UE can directly communicate with a network device. In other words, in Release 17, a remote UE only supports a single path for communicating with a network device at the same time.

[0005] Release 18 is expected to explore schemes that support multipath (multi-path or multiple path). A multipath scenario may be as follows: a remote terminal device connects to the same network device (e.g., gNB) using both a direct path and an indirect path simultaneously. For example, a direct path might refer to the remote terminal device connecting directly to the network device via a Uu interface, while an indirect path might refer to the remote terminal device connecting to the network device via a Layer 2 (L2) UE-to-Network relay.

[0006] Currently, there are no solutions for how to activate at least two paths (direct and indirect paths) simultaneously and how to dynamically switch between at least two paths when skipping multipath routes.

While the specification and drawings disclose specific embodiments of the present invention, these represent only a limited number of embodiments in which the principles of the present invention can be employed. It should be understood that the present invention is not limited to the described embodiments, but rather includes all modifications, variations, and substitutions within the scope of the attached claims.

[0024] In embodiments of the present invention, the terms "communication network" or "wireless communication network" may refer to a network conforming to any communication standard such as LTE (Long Term Evolution), LTE-A (LTE-Advanced), WCDMA (registered trademark) (Wideband Code Division Multiple Access), HSPA (High-Speed ​​Packet Access), etc.

[0026] In embodiments of the present invention, the term "network device" refers, for example, to a device in a communication system that connects terminal devices to a communication network and provides services to said terminal devices. Network devices may include, but are not limited to, the following: "nodes" and / or "donors" under the IAB architecture, base stations (BS), access points (AP), transmission and reception points (TRP), broadcast transmitters, mobile management entities (MME), network gateways, servers, radio network controllers (RNC), base station controllers (BSC), etc.

For example, a 5G base station gNB may include one gNB CU and one or more gNB DUs, where the CU / DU is a logical node of the gNB having some of the functions of the gNB. The term “cell” may refer to a base station and / or the area it covers, depending on the context in which the term is used.

[0028] In embodiments of the present invention, the terms "User Equipment" (UE) or "Terminal Equipment" (TE) refer to devices that access a communication network via network equipment and receive services from the network. User equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), terminal, subscriber station (SS), access terminal (AT), or station.

[0032] The following examples illustrate UE-to-Network Relay scenarios, but the present invention is not limited thereto.

[0033] Figure 1 shows scenario 1 of relaying from a remote user device to a network device, Figure 2 shows scenario 2 of relaying from a remote user device to a network device, and Figure 3 shows scenario 3 of relaying from a remote user device to a network device.

[0034] As shown in Figure 1, in Scenario 1, the first terminal device 101 (remote terminal device (also called remote user device)) is outside the coverage (OOC) of the network device 103, and the second terminal device 102 (relay terminal device (also called relay user device)) is within the coverage (IC) of the network device 103.

[0035] As shown in Figure 2, in Scenario 2, the first terminal device 101 (remote terminal device) is within the coverage (IC) of the network device 103, and the second terminal device 102 (relay terminal device) is also within the coverage of the network device 103.

[0036] As shown in Figure 3, in Scenario 3, the first terminal device 101 (remote terminal device) is within the coverage of network device 103, and the second terminal device 102 (relay terminal device) is within the coverage of another network device 103'.

[0037] Figure 4 shows a communication system in an embodiment of the present invention, illustrating an example where a remote terminal device, a relay terminal device, and a network device are used. As shown in Figure 4, the communication system 400 may include a remote terminal device 401, a relay terminal device 402, and a network device 403, and the remote terminal device 401 is connected to the network device 403 by direct and indirect paths. For the sake of explanation, Figure 4 uses two terminal devices (one remote terminal device and one relay terminal device) and one network device as examples, but embodiments of the present invention are not limited to these.

[0038] In embodiments of the present invention, existing or future operational tasks (traffic) may be performed between the network device 403 and the remote terminal device 401 and relay terminal device 402. For example, these tasks may include, but are not limited to, eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable and Low-Latency Communication).

[0039] Figure 5 shows a multipath scenario in an embodiment of the present invention. As shown in Figure 5, in an embodiment of the present invention, a remote terminal device can communicate with network devices simultaneously via both direct and indirect paths. For example, a remote terminal device can communicate with network devices via a Uu interface (direct path) and also communicate with the same network devices via a relay terminal device (indirect path).

[0040] Figure 6 shows the multipath protocol stack structure in an embodiment of the present invention. As shown in Figure 6, the Uu interface protocol stack is used for the direct path between the remote terminal device and the network device, while the PC5 interface and Uu interface protocol stack are used for the indirect path between the remote terminal device and the network device, where transmission takes place via the L2 UE-to-Network relay.

[0041] In some embodiments, as shown in Figure 6, the RRC, SDAP, and PDCP layers within the remote terminal device are equivalent to the RRC, SDAP, and PDCP layers within the network device. PDCP layer data from the remote terminal device can be transmitted to the network device via an indirect path through the relay terminal device. For example, the PDCP PDU from the remote terminal device can be transmitted to the relay UE via PC5-SRAP, PC5-RLC, PC5-MAC, and PC5-PHY. The relay UE can then transmit the data to the gNB via its own Uu interface protocol stack (Uu SRAP, Uu-RLC, Uu-MAC, and Uu-PHY). The gNB receives this data from the Uu interface protocol stack equivalent to that of the relay UE and transmits it to the gNB's Uu-PDCP for processing. Alternatively, PDCP layer data from a remote terminal device can be transmitted to a network device via a direct path. For example, the PDCP PDU of a remote terminal device can be transmitted to the gNB via Uu-RLC, Uu-MAC, and Uu-PHY. The gNB receives this data from a Uu interface protocol stack equivalent to that of the remote UE and transmits it to the gNB's Uu-PDCP for processing. In addition, one or more RLC entities (Uu-RLC entities or PC5-RLC entities) may be associated with a single wireless bearer's PDCP entity via the direct and / or indirect paths.

[0042] In some embodiments, as shown in Figure 6, the gNB-side protocol stack may use a single Uu-MAC entity to process data from remote terminal devices and relay terminal devices.

[0043] In some embodiments, as shown in Figure 6, the remote terminal device may use a single MAC entity to perform operations on both the PC5-MAC and the Uu-MAC.

[0044] The following describes various embodiments of the present invention in conjunction with the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0045] <Example of the first side view> An embodiment of the present invention provides a method for processing multipath, which is applied to remote user equipment. For example, the method is applied to remote user equipment 401 in Figure 4.

[0046] Figure 7 shows a multi-pass processing method in an embodiment of the first aspect of the present invention. As shown in Figure 7, the method includes the following steps.

[0047] 701: Receive instruction information, which includes information on the activation and / or deactivation and / or switching of direct paths, and / or information on the activation and / or deactivation and / or switching of indirect paths; and 702: Based on the instruction information, the direct path is activated and / or deactivated and / or switched, and / or the indirect path is activated and / or deactivated and / or switched.

[0048] Figure 7 above is provided to illustrate an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation (step) can be appropriately adjusted, or some operations can be added or removed. Those skilled in the art can make appropriate modifications based on the above description, not limited to the description in Figure 7.

[0049] According to the above embodiment, the remote user device can receive instruction information and activate and / or deactivate and / or switch direct paths based on the instruction information, and / or the remote user device can receive instruction information and activate and / or deactivate and / or switch indirect paths based on the instruction information. This allows for activation and / or deactivation and / or switching of paths for the remote user device in a multipath scheme, enabling dynamic adjustment of the use of each path in the multipath and improving the reliability and rate of data transmission for the remote user device.

[0050] In embodiments of the present invention, direct and / or indirect pathways can be activated.

[0051] The direct path awaiting activation may be a pre-configured direct path between the remote user device and the network device, and this path may be in an inactive state or in a state immediately after configuration (just configured). The present invention is not limited thereto, and the direct path awaiting activation may also be an active path, thereby allowing the direct path between the remote user device and the network device to be reactivated or reactivated based on the instruction information described above.

[0052] The indirect path awaiting activation may be a pre-configured indirect path between the remote user device and the network device, and this path may be in an inactive state or in a state immediately after configuration. The present invention is not limited thereto, and the indirect path awaiting activation may also be an active path, thereby allowing the indirect path between the remote user device and the network device to be reactivated or reactivated based on the instruction information described above.

[0053] In some embodiments, when a direct path is activated, an indirect path may exist between the remote user device and the network device, thereby enabling the transmission of the instruction information via the indirect path.

[0054] In some embodiments, when an indirect path is activated, a direct path can exist between the remote user device and the network device, thereby allowing the instruction information to be transmitted via the direct path.

[0055] In embodiments of the present invention, direct and / or indirect pathways can be deactivated.

[0056] After deactivating the direct path, the remote user equipment and network equipment can maintain the settings of the deactivated direct path so that they can be quickly restored by activating the direct path in the subsequent communication process using the instruction information described above. However, the present invention is not limited thereto, and the remote user equipment and network equipment may not maintain the settings of the deactivated direct path, but may instead reconfigure the direct path using the configuration information of the network equipment.

[0057] After deactivating the indirect path, the remote user equipment and network equipment can maintain the settings of the inactive indirect path so that they can quickly restore the indirect path by activating it in the subsequent communication process using the instruction information described above. However, the present invention is not limited thereto, and the remote user equipment and network equipment may not maintain the settings of the inactive indirect path, but may instead reconfigure the indirect path using the configuration information of the network equipment.

[0058] In some embodiments, when a direct path is deactivated, an indirect path may also exist between the remote user equipment and the network equipment, and this indirect path may be active or inactive. Alternatively, when a direct path is deactivated, an indirect path may not exist between the remote user equipment and the network installation; for example, no indirect path may be set.

[0059] In some embodiments, when an indirect path is deactivated, a direct path may also exist between the remote user equipment and the network equipment, and this direct path may be active or inactive. Alternatively, when an indirect path is deactivated, a direct path may not exist between the remote user equipment and the network installation; for example, no direct path may be established.

[0060] In embodiments of the present invention, a handover can be performed for direct and / or indirect paths.

[0061] The switching of a direct path or an indirect path may be at least one of the following: switching from a direct path to an indirect path, or switching from an indirect path to a direct path, or switching from a multipath (direct and indirect paths) to a direct path, or switching from a multipath (direct and indirect paths) to an indirect path, or switching from a direct path to a multipath (direct and indirect paths), or switching from an indirect path to a multipath (direct and indirect paths), etc.

[0062] In some embodiments, direct and / or indirect paths can be dynamically activated and / or deactivated and / or switched based on channel status information. This is advantageous because it allows for the selection of a high-quality and / or low-latency path for communication, thereby saving radio resources on the Uu interface and / or PC5 interface and / or reducing data transmission delay. However, the present invention is not limited thereto, and direct and / or indirect paths can also be activated and / or deactivated and / or switched based on other indicators.

[0063] In some embodiments, multiple transmission methods may be employed in direct and indirect paths.

[0064] For example, a split transmission method can be used for both direct and indirect paths. For instance, network equipment can be configured to use a split transmission method for both direct and indirect paths for all or one wireless bearer of a single remote user device. In this case, different data, such as different PDCP PDUs, can be transmitted through the direct and indirect paths. This can increase throughput.

[0065] For example, some PDCP PDUs may be transmitted in all RLC entities and / or logical channels corresponding to the RB included in the direct path, while other portions of the PDCP PDUs may be transmitted in all RLC entities and / or logical channels corresponding to the RB included in the indirect path.

[0066] Furthermore, for example, some PDCP PDUs may be transmitted in one or more RLC entities and / or logical channels corresponding to the RB included in the direct path, another portion of the PDCP PDUs may be transmitted in one or more other RLC entities and / or logical channels corresponding to the RB included in the direct path, and yet another portion of the PDCP PDUs may be transmitted in all RLC entities and / or logical channels corresponding to the RB included in the indirect path.

[0067] Furthermore, for example, some PDCP PDUs may be transmitted in all RLC entities and / or logical channels corresponding to the RB included in the direct path, another portion of the PDCP PDUs may be transmitted in one or more RLC entities and / or logical channels corresponding to the RB included in the indirect path, and other portions of the PDCP PDUs may be transmitted in one or more other RLC entities and / or logical channels corresponding to the RB included in the indirect path.

[0068] Furthermore, for example, some PDCP PDUs may be transmitted in one or more RLC entities and / or logical channels corresponding to the RB included in the direct path, another portion of the PDCP PDUs may be transmitted in one or more other RLC entities and / or logical channels corresponding to the RB included in the direct path, another portion of the PDCP PDUs may be transmitted in one or more RLC entities and / or logical channels corresponding to the RB included in the indirect path, and the remaining portion of the PDCP PDUs may be transmitted in one or more other RLC entities and / or logical channels corresponding to the RB included in the indirect path.

[0069] For example, a duplication transmission method can be used for both direct and indirect paths. For instance, a network device can be configured to use a duplication transmission method for both direct and indirect paths for all or one wireless bearer of a single remote user device. In this case, the same data, such as the same PDCP PDU, can be transmitted through both the direct and indirect paths, and these same PDCP PDUs may be transmitted through all RLC entities and / or logical channels corresponding to the RB included in the direct path, and all RLC entities and / or logical channels corresponding to the RB included in the indirect path. This ensures the reliability of data transmission for remote user devices.

[0070] In some embodiments, network equipment and / or remote user equipment can dynamically select between direct and indirect transmission methods based on channel status information, business type information, etc. This is advantageous for increasing the throughput of the communication system and ensuring data transmission quality. However, the present invention is not limited to this, and the transmission method may be selected based on other indicators.

[0071] In some embodiments, remote user equipment can receive instruction information transmitted by network equipment, for example, by direct means. Alternatively, remote user equipment can also receive instruction information transmitted by relay user equipment, for example, by PC5 interface or sidelink.

[0072] For the sake of explanation, the instruction information transmitted by network devices will be referred to as the first instruction information, and the instruction information transmitted by relay user devices will be referred to as the third instruction information.

[0073] In some embodiments, the first instruction information includes at least one of the following: a Data Radio Bearer (DRB) identifier, a path identifier or index, a Logic Channel Identity (LCID) or index, a Radio Link Control (RLC) entity (or bearer or channel) identifier or index, path usage instruction information, or path status instruction information. In other words, the first instruction information may be one or any combination of these pieces of information.

[0074] In some embodiments, the DRB indicator in the first instruction information may be a DRB indicator corresponding to a path awaiting activation / switching, or the DRB indicator may be a DRB indicator corresponding to a path awaiting deactivation. After receiving the DRB indicator, the remote user equipment can activate and / or deactivate and / or switch the corresponding path based on the DRB indicator and the correspondence between the DRB indicator and the path.

[0075] In some embodiments, the first instruction information transmitted by the network device to the remote user device may include instruction information for the direct path, or instruction information for the indirect path, or instruction information for both the direct and indirect paths. The first instruction information can distinguish between the direct and indirect paths by path identifiers or indices. Of these, the remote user device can receive information transmitted by the network device via the direct path for deactivating / switching the direct path itself, or can receive information via the direct path for activating / deactivating / switching the indirect path.

[0076] In some embodiments, logical channel indicators or indices or RLC entity (or bearer or channel) indicators or indices are used to activate or deactivate RLC entities (or bearers or channels) and / or logical channels when a single wireless bearer supports transmission using multiple RLC entities (or bearers or channels) and / or logical channels in an indirect path PC5 interface.

[0077] In some embodiments, the path usage instruction information may be information that instructs the use of split transmission or overlapping transmission between the direct path and the indirect path.

[0078] In some embodiments, the path state indication information may also be information that instructs the direct path and / or indirect path to be activated and / or deactivated and / or switched.

[0079] In some embodiments, the first indicator information can be a bitmap that indicates the active or inactive state of a path corresponding to a DRB indicator or index. This can reduce signaling overhead.

[0080] Figure 8 shows a bitmap in an embodiment of the first aspect of the present invention. As shown in Figure 8, the bitmap can be used to indicate the active or inactive state of direct and / or indirect paths corresponding to DRBs. For example, taking a direct path as an example, when the direct path can be used for data transmission of n DRBs, the bitmap (b0, b1, ..., b i , ..., b n-1 )(wherein n is 1 or greater, i is 0 or greater, and n is less than or equal to n) respectively indicate the active or inactive state of the path corresponding to DRB index 0 to n-1, or a bitmap (b n-1 , b n-2 , ..., b iThe bitmap(b0, b1, ..., b0) indicates the active or inactive state of the path corresponding to DRB index n-1 to 0, respectively, and the DRB indexes are sorted in ascending or descending order of DRB ID. i , ..., b n-1 Taking the example of ), the remote user device receives the bitmap from the direct path and activates the direct path of the DRB corresponding to one bit in the bitmap if it is instructed to activate by that bit, and deactivates the direct path of the DRB corresponding to one bit in the bitmap if it is instructed to deactivate by that bit. The method for determining the activation and deactivation of the indirect path is the same as for the direct path, and a detailed explanation is omitted here. The present invention is not limited thereto, and the active or inactive state of the path may be indicated by other forms of bitmaps. In some embodiments, the first instruction information may be transmitted by a Radio Resource Control (RRC) message, a Packet Data Convergence Protocol (PDCP) control packet data unit (PDU), or a Media Access Control (MAC) control element (CE). The present invention is not limited thereto, and the first instruction information may be transmitted by other methods.

[0081] In some embodiments, the third instruction information transmitted by the relay user equipment includes at least one of the following: a DRB indicator, a logical channel indicator (LCID) or index, an RLC entity (or bearer or channel) indicator or index, or path state indicator information. In other words, the third instruction information may be one of these pieces of information or any combination thereof.

[0082] In some embodiments, the third instruction information transmitted by the relay user device to the remote user device may include instruction information about the indirect path. The remote user device can then receive information via the indirect path to deactivate / switch the indirect path itself. The third instruction information may omit path identifiers or index information. This reduces signaling overhead.

[0083] The present invention is not limited thereto, and the third instruction information transmitted by the relay user device to the remote user device may include instruction information for the direct path. Of these, the remote user device can receive information via the indirect path to activate / deactivate / switch the direct path.

[0084] In some embodiments, the DRB indicator in the third instruction information may be a DRB indicator corresponding to a path awaiting activation / switching, or the DRB indicator may be a DRB indicator corresponding to a path awaiting deactivation. After receiving the DRB indicator, the remote user equipment can activate and / or deactivate and / or switch the corresponding path based on the DRB indicator, for example, by activating and / or deactivating and / or switching the PC5 connection with the relay user equipment.

[0089] In some embodiments, the third instruction information transmitted by the relay user device may be information generated by the relay user device itself. Alternatively, the third instruction information may be information generated by the relay user device based on the instruction information transmitted by the network device (for example, this instruction information may be the second instruction information described in the embodiments below). In other words, the relay user device receives the instruction information transmitted by the network device and generates the third instruction information to be transmitted to the remote user device based on this instruction information.

[0090] In some embodiments, the instruction information transmitted by the network device to the relay user device may include at least one of the following: a DRB indicator, a logical channel indicator (LCID) or index, an RLC entity (or bearer or channel) indicator or index, or path status instruction information.

[0092] In some embodiments, the remote user device can receive first instruction information transmitted by the network device or third instruction information transmitted by the relay user device, and activate and / or deactivate and / or switch the path based on the first or third instruction information. Alternatively, the remote user device can receive first instruction information transmitted by the network device and third instruction information transmitted by the relay user device, and activate and / or deactivate and / or switch the path based on the first and third instruction information.
