Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission method and apparatus for Configured Grant (CG). Background Art

[0002] With the continuous development of wireless communication, the requirements for mobility, transmission latency, and system capacity are getting higher and higher. 3GPP completed the standardization work of L1 (Layer 1) / L2 (Layer 2) Triggered Mobility (LTM) through the "Further NR mobility enhancements" Work Item (WI) in Release 18; among them, it supports configuring CG resources for candidate cells and performing RACH-less LTM cell switch on candidate cells.

[0003] To further enhance mobility, Conditional LTM has become an important research content in 3GPP Release 19. Summary of the Invention

[0004] For Release 18 RACH-less LTM cell switching, if the UE receives an LTM CellSwitch Command MAC (Medium Access Control) CE (Control Element) indicating the TCI (Transmission Configuration Indicator) state of a candidate cell, the SSB (Synchronization Signal Block, or SS (Synchronization Signal) / PBCH (Physical Broadcast Channel) block) associated with the CG resources to be transmitted on the candidate cell needs to be the same as the SSB associated with the TCI state indicated by the LTM Cell Switch Command MAC CE. The inventors found through research that for conditional LTM, if the UE does not receive the LTM Cell Switch Command MAC CE, the network cannot indicate the TCI state, and thus it cannot be determined through network indication. Therefore, for conditional LTM, how to determine the CG resources to be transmitted on the candidate cell is a problem that needs to be studied.

[0005] In view of the above problems, the present application provides a solution for CG. In the above problem description, the NR system is taken as an example, and the present application is also applicable to scenarios of future systems such as 5G-A or 6G, achieving technical effects similar to those of the NR system; further, although the present application gives specific implementation manners for LTM, the present application can also be used in scenarios such as CHO (Conditional Handover) or CPC (Conditional PSCell (Primary SCG (Secondary Cell Group) Cell) Change), achieving technical effects similar to those of LTM. Further, adopting a unified design solution for different scenarios also helps to reduce hardware complexity and cost. Further, although the present application gives specific implementation manners for cell-level mobility, the present application can also be used in scenarios of beam-level mobility, achieving technical effects similar to those of cell-level mobility. Further, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 interface, achieving technical effects similar to those of the Uu air interface. Further, although the original intention of the present application is for the scenario of the terminal and the base station, the present application is also equally applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between the terminal and the relay, and between the relay and the base station, achieving technical effects similar to those in the scenario of the terminal and the base station. Further, although the original intention of the present application is for the scenario of the terminal and the base station, the present application is also equally applicable to the communication scenario of IAB (Integrated Access and Backhaul), achieving technical effects similar to those in the scenario of the terminal and the base station. Further, although the original intention of the present application is for the Terrestrial Network (TN) scenario, the present application is also equally applicable to the communication scenario of the Non-Terrestrial Network (NTN), achieving technical effects similar to those in the TN scenario. In addition, adopting a unified solution for different scenarios also helps to reduce hardware complexity and cost.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture for controlling plane 300 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 text. Layer 2 (L2 layer) 305 is above PHY301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels.

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 disordered reception due to HARQ (Hybrid Automatic Repeat Request).

[0427] Example 4

[0428] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 as shown. Figure 4 It is a block diagram of a first communication device 450 and a second communication device 410 that communicate with each other in an access network.

[0429] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0430] The second communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0431] In the 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 the 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 encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and 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 on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmission analog precoding / beamforming operations 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 different antennas 420.

[0432] 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 signals through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream and provides it to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations 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 receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 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. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs 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. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0433] 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 a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function described at the second communication device 410 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 both the user plane and the control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing. A multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after passing through an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. 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.

[0434] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receiving functions described at the first communication device 450 in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency 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 jointly implement L1 layer functions. A controller / processor 475 implements L2 layer functions. 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 the transmission from the first communication device 450 to the second communication 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. The upper layer data packets from the controller / processor 475 may be provided to the core network.
