Description

A method and device for wireless communication Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and to triggering of wireless link failure and mobility management. Background Art

[0002] The application scenarios of future wireless communication systems will become increasingly diverse, and different scenarios will place varying performance requirements on the systems. To meet these diverse performance demands, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) plenary meeting #72 decided to conduct research on New Radio (NR) (or Fifth Generation, 5G). The NR Work Item (WI) was approved at the 3GPP RAN plenary meeting #75, initiating standardization work on NR.

[0003] In communications, both LTE (Long Term Evolution) and 5G NR require reliable and accurate information reception, optimized energy efficiency, determination of information validity, flexible resource allocation, scalable system architecture, efficient non-access layer information processing, low service interruption and call drop rates, and support for low power consumption. These requirements are crucial for normal communication between base stations and user devices, rational resource scheduling, and system load balancing. They are the cornerstone for achieving high throughput, meeting the communication needs of various services, improving spectrum utilization, and enhancing service quality. They are indispensable for eMBB (enhanced Mobile Broadband), URLLC (Ultra Reliable Low Latency Communication), and eMTC (enhanced Machine Type Communication). At the same time, there are extensive demands in the IIoT (Industrial Internet of Things), V2X (Vehicular to X), device-to-device communication, unlicensed spectrum communication, user communication quality monitoring, network planning and optimization, NTN (Non Territerial Network), TN (Territerial Network), dual connectivity systems, wireless resource management and multi-antenna codebook selection, signaling design, neighboring cell management, service management, and beamforming. Information is sent in two ways: broadcast and unicast. Both transmission methods are essential for 5G systems because they are very helpful in meeting the above requirements. The UE can connect to the network directly or through a relay.

[0004] As the scenarios and complexity of the system continue to increase, higher requirements are placed on reducing interruption rates, reducing latency, enhancing reliability, enhancing system stability, business flexibility, and saving power. At the same time, compatibility between different system versions also needs to be considered during system design.

[0283] FIG2 illustrates a diagram of a network architecture 200 for 5G NR, LTE (Long-Term Evolution), and LTE-A (Long-Term Evolution Advanced) systems. The 5G NR or LTE network architecture 200 may be referred to as a 5G System (5GS) / EPS (Evolved Packet System) 200 or some other suitable terminology. The 5GS / EPS 200 may include one or more User Equipment (UE) 201, an NG-RAN (Next Generation Radio Access Network) 202, a 5G Core Network (5GC) / EPC (Evolved Packet Core) 210, a Home Subscriber Server (HSS) / UDM (Unified Data Management) 220, and Internet services 230. The 5GS / EPS may interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown, the 5GS / EPS provides packet-switched services, but those skilled in the art will readily appreciate that the various concepts presented throughout this disclosure can be extended to networks providing circuit-switched services or other cellular networks. The NG-RAN includes an NR Node B (gNB) 203 and other gNBs 204. The gNB 203 provides user and control plane protocol termination towards the UE 201.

[0296] Example 3

[0297] Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in FIG3 . FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the radio protocol architecture of the control plane 300 between a first node (a UE, a gNB, or a satellite or aircraft in an NTN) and a second node (a gNB, a UE, or a satellite or aircraft in an NTN), or between two UEs, using 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 herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first and second nodes, as well as between two UEs, via PHY 301. 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 multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets, and provides support for inter-zone mobility of the first node between the second node. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. 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 operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring lower layers using RRC signaling between the second node and the first node. The PC5-S (PC5 Signaling Protocol) sublayer 307 is responsible for processing the signaling protocol of the PC5 interface. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second nodes in the user plane 350 is generally the same as the corresponding layers and sublayers in the control plane 300, including 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. However, the PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping QoS flows and data radio bearers (DRBs) to support service diversity. SRBs can be seen as services or interfaces provided by the PDCP layer to higher layers, such as the RRC layer. In the NR system, SRBs include SRB1, SRB2, SRB3, and SRB4 when sidelink communication is involved, which are used to transmit different types of control signaling. SRBs are bearers between the UE and the access network, used to transmit control signaling, including RRC signaling, between the UE and the access network. SRB1 is of special significance to the UE. After each UE establishes an RRC connection, it will have SRB1 for transmitting RRC signaling. Most signaling is transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must perform RRC re-establishment. SRB2 is generally only used to transmit NAS signaling or security-related signaling. The UE can not configure SRB3. Except for emergency services, the UE must establish an RRC connection with the network for subsequent communications. Although not shown in the figure, the first node may have several upper layers above the L2 layer 355. In addition, it also includes a network layer (for example, an IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (for example, a remote UE, a server, etc.). For UEs involved in relay services, its control plane may also include an adaptation sublayer SRAP (Sidelink Relay Adaptation Protocol) 308, and its user plane may also include an adaptation sublayer SRAP358. The introduction of the adaptation layer helps lower layers, such as the MAC layer, such as the RLC layer, to multiplex and / or distinguish data from multiple source UEs. For nodes not involved in relay communication, PC5-S307, SRAP308, and SRAP358 are not required during the communication process.

[0298] As an embodiment, the wireless protocol architecture in FIG3 is applicable to the first node in this application.

[0299] As an embodiment, the wireless protocol architecture in FIG3 is applicable to the second node in this application.

[0300] As an embodiment, the first signaling in this application is generated in RRC306.

[0301] As an embodiment, the first RRC information block in this application is generated in RRC306.

[0302] As an embodiment, the signal requesting scheduling on the SR or PUCCH in this application is generated by PHY301.

[0303] Example 4

[0304] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0305] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, and optionally may also include a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454 and an antenna 452.

[0306] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receive processor 470 , a transmit processor 416 , and optionally may also include a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0307] During transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to the controller / processor 475 at the second communication device 410. The controller / processor 475 implements Layer 2 (L2) functionality. During transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the Layer 1 (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, as well as mapping of signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to a different antenna 420.

[0308] During transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal via its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream, after the receive analog precoding / beamforming operations, from the time domain to the frequency domain using a fast Fourier transform (FFT). In the frequency domain, the receive processor 456 demultiplexes the physical layer data signal and reference signal, where the reference signal is used for channel estimation. The data signal undergoes multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. During transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 layer for L3 processing.

[0309] During transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 to provide upper layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functionality at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, the stream is provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a RF symbol stream before providing it to the antenna 452.

[0310] During transmission from the first communications device 450 to the second communications device 410, the functionality at the second communications device 410 is similar to the reception functionality at the first communications device 450 described for transmission from the second communications device 410 to the first communications device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF signals into baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement L1 layer functionality. A controller / processor 475 implements L2 layer functionality. The controller / processor 475 may be associated with a memory 476 storing program codes and data. The memory 476 may be referred to as a computer-readable medium. During transmission from the first communications device 450 to the second communications device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
