Description
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for mobility.
Background
For 3GPP (3 rd GenerationPartner Project, third generation partnership project) systems, in the RRC (Radio Resource Control ) CONNECTED state, the base station is responsible for maintaining the timing advance for maintaining L1 (layer 1) synchronization. Cells with the same timing advance and using the same timing reference are grouped in one TAG (Timing Advance Group ), each TAG comprising at least one Serving Cell (Serving Cell) configured for uplink, the RRC layer being responsible for the mapping of each Serving Cell to TAG. For PTAG (Primary TAG), spCell (Special Cell) is the timing reference of the cells in the PTAG, and for one STAG (Secondary TAG), any activated SCell (Secondary Cell) in this STAG serves as the timing reference of the cells in this STAG (Timing Reference Cell). The timing advance update is notified to the UE by the base station through a MAC (Medium Access Control, media access Control) CE (Control Element) command. If L1 is considered unsynchronized, the UE (User Equipment) can only send MSG1 (Message 1 ) or MSGA (Message a, message a) on the uplink.
Disclosure of Invention
One timing reference cannot continue as a timing reference in some cases, for example, when a PCell (Primary Cell) performs a handover based on L3 (layer 3, layer three) signaling, or when a PSCell (Primary SCG (Secondary Cell Group, secondary Cell group) Cell, SCG Primary Cell) performs a PSCell change based on L3 signaling, or when an SCell as a timing reference is deactivated, the UE needs to change the timing reference. When a UE moves from the coverage area of one cell to the coverage area of another cell, a change of serving cell needs to be performed, the timing reference is predefined, or the timing reference is UE-selected, and the base station cannot decide the selection of the timing reference. In existing protocols, serving Cell change is triggered by L3 measurement and synchronous reconfiguration of PCell (Primary Cell) and PSCell is triggered by RRC signaling and release of SCell is triggered, which operations may involve L2 (layer 2, layer two) and L1 reset, resulting in longer Delay, greater Overhead and longer interruption time (interruption time). In Rel-18, the 3GPP RAN94e conference decides to develop a "NR (New Radio, new air interface) mobility further enhancement (Further NR mobility enhancements)" study Item (Work Item, WI) for a study direction where mobility enhancement is important for 3 GPP. Among them, reducing latency, overhead and outage time through L1/L2 mobility enhancement based on L1/L2 signaling or continuous CPC (Conditional PSCell Change) mechanism is an important research direction, leading to frequent changes of serving cells. When the serving cell changes frequently, the timing reference is also changed frequently, resulting in an impact on the uplink transmission. Thus, for a scenario where the serving cell transitions faster, how to determine the timing reference needs to be enhanced.
In view of the above, the present application provides a solution to maintaining uplink synchronization for L1/L2 mobility. In the description for the above problems, an L1/L2-based mobility scenario is taken as an example; the application is equally applicable to e.g. L3 based mobility scenarios, achieving technical effects similar to those in L1/L2 based mobility. Further, while the present application is initially directed to Uu air interfaces, the present application can also be used for PC5 interfaces. Further, although the present application is initially directed to a terminal and base station scenario, the present application is also applicable to a V2X (Vehicle-to-internet) scenario, a communication scenario between a terminal and a relay, and a communication scenario between a relay and a base station, and similar technical effects in the terminal and base station scenario are obtained. Further, although the present application is initially directed to the terminal and base station scenario, the present application is also applicable to the communication scenario of IAB (Integrated Access and Backhaul ), and achieves similar technical effects in the terminal and base station scenario. Further, although the present application is initially directed to a terrestrial network (Terrestrial Network ) scenario, the present application is equally applicable to a Non-terrestrial network (Non-Terrestrial Network, NTN) communication scenario, achieving similar technical effects in a TN scenario. Furthermore, the adoption of a unified solution for different scenarios also helps to reduce hardware complexity and cost.

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.
In the transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the second communication device 410. 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, a 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as mapping of signal clusters 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 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) 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 multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.
In a transmission from the second communication device 410 to the first communication device 450, each receiver 454 receives a signal at the first communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A 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 multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in a 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 that were 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. Memory 460 may be referred to as a computer-readable medium. In the 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, control signal processing to recover upper layer data packets from the core network. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.
In the 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 a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions 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 allocations, implementing L2 layer functions for the user and control planes. 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, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the 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 radio frequency symbol stream and provides it to an antenna 452.
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 receiving 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to 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 the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. 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, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network.
