Description

Technical Field

[0001] The present application relates to methods and devices in wireless communication systems, and more particularly to methods and devices supporting relay transmission in secondary link wireless communication. Background Art

[0002] Relay, as a multi-hop transmission technology, can improve cell edge throughput and cell coverage. Taking the sidelink SL transmission in the LTE (Long Term Evolution) system as an example, the transmission from the user equipment (UE) to the relay node (RN) uses the sidelink air interface technology, and the transmission from the RN to the base station (eNodeB, eNB) uses the LTE air interface technology. RN is used for data forwarding between the UE and the eNB, which is called IP (Internet Protocol) layer forwarding or Layer 3 Relay (Layer 3 Relay / L3 Relay).

[0003] In the future, the application scenarios of wireless communication systems will become more and more diversified, and different application scenarios will put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study the NR (New Radio) technology (or Fifth Generation, 5G), and the NR WI (Work Item) was passed at the 3GPP RAN #75 plenary meeting, and the standardization work on NR began. In response to the rapid development of V2X (Vehicle-to-Everything) business, 3GPP also started the standardization and research work under the NR framework, and decided to start the SI (Study Item) standardization work on NR SL (Sidelink) Relay at the 3GPP RAN #86 plenary meeting. Summary of the invention

[0004] The inventors found through research that NR V2X supports a variety of application scenarios, including at least 25 services in four categories, each of which has different QoS (Quality of Service) requirements. Different QoS requirements are defined by different QoS parameter groups (Parameters). The parameters included in the QoS parameter group include but are not limited to PQI (PC5 5G QoS Identifier, PC5 5G quality identifier), PC5 Flow bit rate (PC5 flow bit rate), PC5 Link Aggregated Bit Rate (PC5 link aggregate bit rate), and one or more of Range (transmission distance). The PQI parameter is mapped into a QoS feature on the Tx UE side to control the QoS processing of data packets during transmission. In relay transmission, due to the introduction of relay nodes, the original one-hop transmission from Tx UE to Rx UE is divided into two hops from Tx UE to relay node and relay node to Rx UE. How to allocate QoS parameter groups in these two-hop transmissions to meet the QoS requirements of the service needs to be studied.

[0005] In view of the above problems, the present application discloses a solution. In the description of the present application, only the NR V2X scenario is used as a typical application scenario or example; the present application is also applicable to other scenarios other than NR V2X facing similar problems (such as relay networks, D2D (Device-to-Device, device-to-device) networks, cellular networks, and scenarios supporting half-duplex user equipment), and can also achieve similar technical effects in the NR V2X scenario. In addition, the use of a unified solution for different scenarios (including but not limited to NR V2X scenarios, downlink communication scenarios, etc.) also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in the first node of the present application can be applied to any other node, and vice versa. In the absence of conflict, the embodiments and features in the embodiments of the present application can be arbitrarily combined with each other. In particular, the interpretation of the terms (Terminology), nouns, functions, and variables in the present application (if not otherwise specified) can refer to the definitions in the 3GPP specification protocols TS36 series, TS38 series, and TS37 series.

[0316] Example 3

[0317] Embodiment 3 illustrates a schematic diagram of an embodiment of a protocol architecture of a user plane and a control plane according to the present application, as shown in the attached Figure 3 shown. Figure 3 A schematic diagram illustrating an embodiment of an Access Stratum (AS) radio protocol architecture and a Non-Access Stratum (NAS) protocol architecture for the User Plane 350 and the Control Plane 300 .

[0318] Figure 3 The V2X layer is used to show the protocol architecture of the NAS layer for the first node (UE or RSU in V2X, vehicle-mounted device or vehicle-mounted communication module) and the second node (UE or RSU in V2X, vehicle-mounted device or vehicle-mounted communication module), or between two UEs. In the control plane 300 of the NAS layer, the V2X layer is called V2X307. The V2X layer generates a PC5 QoS parameter group and a QoS rule according to the received service data or service request, generates a PC5 QoS flow corresponding to the PC5 QoS parameter group, and sends the PC5 QoS flow identifier and the corresponding PC5 QoS parameter group to the AS layer for the AS layer to perform QoS processing on the data packet belonging to the PC5 QoS flow identifier. The V2X layer also provides the transmission mode, wireless frequency, and transmission parameter configuration of the PC5 QoS flow to the AS layer. In the data plane 350 of the NAS layer, the V2X layer is called V2X357, and the V2X layer performs QoS processing on the data packet, including classifying the data packet into different PC5 QoS flows, and then sending the data packet and the PC5 QoS flow identifier to the AS layer.

[0319] Figure 3The radio protocol architecture of the control plane 300 of the AS layer between the first node and the second node, or the two UEs is shown in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node and the second node and the two UEs through PHY301. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node. The PDCP sublayer 304 provides data encryption and integrity protection, and the PDCP sublayer 304 also provides inter-zone mobility support for the first node to the second node. The RLC sublayer 303 provides segmentation and reorganization of data packets, and retransmission of lost data packets is achieved through ARQ. The RLC sublayer 303 also provides duplicate data packet detection and protocol error detection. The MAC sublayer 302 provides mapping between logical and transport channels and multiplexing of logical channel identities. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first nodes. The MAC sublayer 302 is also responsible for HARQ (Hybrid Automatic Repeat Request) operations. The RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and using RRC signaling between the second node and the first node to configure the lower layer. The radio protocol architecture of the user plane 350 of the AS layer includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first node and the second node in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 of the AS layer for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce wireless transmission overhead.The L2 layer 355 in the user plane 350 of the AS layer also includes a SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS (Quality of Service) flows and data radio bearers (DRBs) to support the diversity of services. Although not shown in the figure, the first node and the second node, or the two UEs, may have several upper layers above the V2X layer, including a network layer (e.g., an IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

The receiving processor 452 implements various signal receiving processing functions of the L1 layer. The signal receiving processing function includes receiving the physical layer signal, demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., BPSK (Binary Phase Shift Keying, Binary Phase Shift Keying, QPSK (Quadrature Phase Shift Keying)), then descrambling, decoding and deinterleaving to recover the data or control transmitted by the second node 400 on the physical channel, and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the functions of the L2 layer, the V2X layer and above. The controller / processor may be associated with a memory 480 storing program code and data. Data source / storage 480 may be referred to as a computer-readable medium.

[0341] In the transmission from the first node 450 to the second node 400, at the first node 450, the data source / memory 480 is used to provide high-layer data to the controller / processor 490. The data source / memory 480 represents the L2 layer, the V2X layer and all protocol layers above. The controller / processor 490 implements the L2 layer protocol for the user plane and the control plane by providing header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the second node 410. The controller / processor 490 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second node 410. The transmit processor 455 implements various signal transmission processing functions for the L1 layer (i.e., the physical layer).
