Description

Technical Field

[0001] This application relates to a transmission method and apparatus used in a wireless communication system, and particularly to a transmission method and apparatus used for mobility.

Background Art

[0002] With the continuous development of wireless communication, for example, the requirements for mobility, such as shorter interruption delays, are becoming increasingly high. In the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) #94e meeting, it was decided to consider L1 (Layer 1) / L2 (Layer 2) Triggered Mobility (LTM) in the work item (WI) "Further Enhancement of NR (New Radio) Mobility".

Summary of the Invention

[0003] In the prior art, when one DCI (Downlink Control Information) identified by the C (Cell)-RNTI (Radio Network Temporary Identifier) of one cell is received by a user equipment (UE), and in response to the reception of this DCI, when one preamble is transmitted, one bit block in this DCI indicates the air interface resources occupied by this preamble, and the cell associated with this preamble includes this cell. However, when one DCI identified by the C-RNTI of one cell is received by the UE, and in response to the reception of this DCI, when one preamble is transmitted, if the cell associated with this preamble does not include this cell, this DCI determines how to determine whether the cell associated with this preamble includes this cell, and how to determine that the air interface resources occupied by this preamble require expansion.

[0004] In view of the above problems, this application provides a solution for mobility. In the description of the above problems, the NR system is used as an example. This application is also applicable to scenarios such as LTE (Long-Term Evolution) systems, achieving similar technical effects to those of the NR system. Furthermore, although this application provides a specific implementation for LTM, it can also be used in scenarios such as PSCell modification, achieving similar technical effects to those of LTM. Moreover, although the original intent of this application is related to the Uu air interface, this application can also be used for the PC5 interface to achieve similar technical effects to those of the Uu air interface. Furthermore, although the original intent of this application is related to terminal and base station scenarios, this application is also applicable to V2X (Vehicle-to-Everything) scenarios, as well as communication scenarios between terminals and relays, and between relays and base stations, to achieve similar technical effects to those in terminal and base station scenarios. Furthermore, although the original intent of this application is for terminal and base station scenarios, it is also applicable to IAB (Integrated Access and Backhaul) communication scenarios to achieve similar technical effects as in terminal and base station scenarios. Furthermore, although the original intent of this application is for terrestrial network (TN) scenarios, it is also applicable to non-terrestrial network (NTN) communication scenarios to achieve similar technical effects as in TN scenarios. Adopting a unified solution for different scenarios also helps reduce hardware complexity and cost.

Figure 4 is a block diagram of the first communication device 450 and the second communication device 410 communicating with each other within an access network.

[0447] The first communication device 450 comprises a controller / processor 459, memory 460, data source 467, transmission processor 468, receiving processor 456, multi-antenna transmission processor 457, multi-antenna receiving processor 458, transmission / receiving device 454, and antenna 452.

[0448] The second communication device 410 comprises a controller / processor 475, memory 476, a receiving processor 470, a transmission processor 416, a multi-antenna receiving processor 472, a multi-antenna transmission processor 471, a transmission / receiving device 418, and an antenna 420.

[0449] In transmission from the second communication device 410 to the first communication device 450, the second communication device 410 provides the controller / processor 475 with upper-layer data packets from the core network. The controller / processor 475 implements L2 layer functionality. In transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides the first communication device 450 with header compression, encryption, packet splitting and reordering, multiplexing between logical channels and transport channels, and radio resource allocation based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. Transmission processor 416 and multi-antenna transmission processor The sesser 471 implements various signal processing functions for the L1 layer (i.e., the physical layer). The transmission processor 416 implements coding and interleaving to facilitate forward error correction (FEC) in the second communication device 410, and mapping of signal constellations based on various modulation solutions (e.g., two-phase shift modulation (BPSK), four-phase shift modulation (QPSK), M-phase shift modulation (M-PSK), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmission processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, as well as beamforming processing, on the encoded and modulated symbols to generate one or more spatial streams. The transmission processor 416 then maps each spatial stream to subcarriers, multiplexes each spatial stream with a reference signal (e.g., a pilot frequency) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel that carries the time-domain multicarrier symbol stream. Next, the multi-antenna transmission processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmission device 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmission processor 471 into a radio frequency stream, which is then provided to different antennas 420.

[0450] In transmission from the second communication device 410 to the first communication device 450, each receiving device 454 in the first communication device 450 receives the signal via its corresponding antenna 452. Each receiving device 454 reconstructs the information modulated on the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream to be provided 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 receive analog precoding / beamforming operation on the baseband multicarrier symbol stream from the receiving device 454. The receiving processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream, which has undergone the receive analog precoding / beamforming operation, from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receiving processor 456. The reference signal is used for channel estimation, and the data signal undergoes multi-antenna detection in the multi-antenna receiving processor 458 to recover any spatial stream directed to the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. The receiving processor 456 then decodes and deinterleaves the soft decision to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459, which implements the L2 layer functionality. 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.In transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 performs demultiplexing between the transport channel and logical channel, packet reassembly, decoding, header reconstruction, and control signal processing to reconstruct the upper-layer data packets from the core network. The upper-layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

[0451] In transmission from the first communication device 450 to the second communication device 410, the first communication device 450 provides the upper layer data packets to the controller / processor 459 using the data source 467. The data source 467 provides all upper layer data packets. Representing the L2 layer. Similar to the transmission functions in the second communication device 410 as described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements L2 layer functions for the user plane and control plane by performing header compression, encryption, packet segmentation and sorting, and multiplexing between logical channels and transport channels based on radio resource allocation. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. The transmission processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmission processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. The transmission processor 468 then modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmission device 454 after analog precoding / beamforming operations in the multi-antenna transmission processor 457. Each transmission device 454 first converts the baseband symbol stream provided by the multi-antenna transmission processor 457 into a radio frequency symbol stream, and then the radio frequency symbol stream is provided to the antenna 452.

[0452] In transmission from the first communication device 450 to the second communication device 410, the functions of the second communication device 410 are the same as the receiving functions of the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiving device 418 receives a radio frequency signal via its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the functions of the L2 layer. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. In transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 performs multiplexing and isolation between the transport channel and the logical channel, packet reassembly, decoding, header reconstruction, and control signal processing to reconstruct the upper-layer data packets from the UE 450.
