Description

Technical Field

[0001] The present application relates to a method and device for wireless communication, and in particular to a method and device for reporting cell selection information. Background Art

[0002] For existing services or future services (such as XR), when the UE (User Equipment) is highly mobile or moves between high-density cells, it will lead to more unexpected handover failures (HOF), radio link failures, ping-pong, throughput loss, or premature / late handovers. Considering the potential of AI (Artificial Intelligence) / ML (Machine Learning) algorithm-based mechanisms to implement proactive solutions and the relevant progress of RAN1 and RAN3 in AI / ML, 3GPP (the 3rd Generation Partnership Project) has passed the SI (Study Item) "Study on AI / ML for mobility in NR" to study and evaluate the potential benefits and gains of AI / ML-assisted mobility for network-triggered L3-based handovers, including RLF (Radio Link Failure) prediction or HOF (Handover Failure) prediction.

[0003] In the existing system, the cell selection mechanism is not only used in the RRC_IDLE state or the RRC_INACTIVE state, but also in the RRC_CONNECTED state, that is, when the UE encounters a connection failure in the RRC_CONNECTED state, such as RLF or HOF, the RRC connection can be reestablished through the RRC connection reestablishment process. In the RRC connection reestablishment process, the UE determines the cell to attempt RRC connection reestablishment by performing cell selection. After the UE determines the cell to attempt RRC connection reestablishment by performing cell selection in the RRC_CONNECTED state, it sends an RRC connection reestablishment request message on this cell through CCCH (Common Control Channel). Summary of the invention

[0004] Through research, the inventors found that the function of cell selection in the RRC_CONNECTED state is limited by the RRC connection re-establishment process. With the enhancement of mobility, especially the introduction of AI / ML, it is necessary to study how to enhance the cell selection mechanism; including but not limited to, how to perform subsequent operations when a cell meets the cell selection criteria.

[0005] In view of the above problems, the present application provides a solution. In the description of the above problems, the NR system is used as an example. The present application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) or 5G-A or 6G systems, and achieves technical effects similar to those of the NR system; further, although the present application provides a specific implementation method for RLF, the present application can also be used in scenarios such as HOF to achieve technical effects similar to those of RLF. Furthermore, adopting a unified design scheme for different scenarios can also help reduce hardware complexity and cost. Furthermore, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 port to achieve technical effects similar to those of the Uu air interface. Furthermore, although the original intention of the present application is for the terminal and base station scenario, the present application is also applicable to V2X (Vehicle-to-Everything) scenarios, communication scenarios between terminals and relays, and relays and base stations, and achieves technical effects similar to those in terminal and base station scenarios. Furthermore, although the original intention of this application is for the terminal and base station scenario, this application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, and achieves similar technical effects in the terminal and base station scenario. Furthermore, although the original intention of this application is for the terrestrial network (TN) scenario, this application is also applicable to the non-terrestrial network (NTN) communication scenario, and achieves similar technical effects in the TN scenario. In addition, the use of a unified solution for different scenarios can also help reduce hardware complexity and costs.

[0340] Example 4

[0341] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in the attached figure. Figure 4 shown. 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.

[0342] 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, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454 and an antenna 452.

[0343] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receive processor 470 , a transmit processor 416 , a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0344] In transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 layer. In 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 L1 layer (i.e., the 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), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing 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 domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation on the time-domain multi-carrier 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.

[0345] In the 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 through 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 and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving 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 codes and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the 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 L3 for L3 processing.

[0346] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used 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 function 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, and implements L2 layer functions for user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream, and then provides it to the antenna 452.

[0347] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the UE 450.
