Description

1 / 83 “METHOD AND APPARATUS USED IN NO FOR WIRELESS COMMUNICATIONS” FIELD OF TECHNOLOGY

[0001] This application relates to methods and apparatus for transmitting wireless communication systems, in particular, to a method and apparatus for transmitting wireless signals. BACKGROUND OF THE TECHNIQUE

[0002] In the future, the application scenarios for wireless communication systems will become increasingly diverse, and different application scenarios will place different performance requirements on the system. To meet the different performance needs of various application scenarios, it was decided to study a new radio (NR) (or 5G) technology at the 72nd plenary meeting of the 3rd generation partnership project (3GPP) for radio access network (RAN), and a work item (WI) for new radio (NR) technology was adopted at the 75th plenary meeting of the 3GPP RAN to initiate the work of standardizing NR.

[0003] User equipment (UE) mobility is an important feature of wireless networks.Changes to existing server cells are typically triggered by Layer 3 (L3) measurements and implemented via a synchronization-triggered reconfiguration using Radio Resource Control (RRC) signaling, which also involves Layer 2 (L2) and Layer 1 (L1) resets. L3-triggered server cell changes are characterized by long latency, high signaling overhead, and long downtime. To further improve UE mobility performance, the 3GPP RAN meeting #94e decided to hold a WI on “Further NR Mobility Enhancements”. L1 / L2 triggered mobility (LTM) is a key research direction for reducing latency, overhead, and downtime. SUMMARY OF THE INVENTION

[0004] In existing standards, a terminal needs to apply RRC layer configuration parameters when performing uplink transmissions based on dynamic scheduling and configuration grants. Additionally, when the timeAlignmentTimer expires, an uplink grant for a cell in a Petition 870250112631, dated 08 / 12 / 2025, page 7 / 94 2 / 83 The corresponding cell group is released. The uplink grant is only executed after the terminal receives the air interface signaling to activate or reconfigure the uplink grant. In an L1 / L2 triggered mobility management scenario, the UE does not need to receive a reconfiguration triggered by RRC signaling with synchronization. Therefore, further research is needed on how to quickly acquire an uplink resource, reduce latency, and shorten downtime during handover to a target cell.

[0005] In response to the problems mentioned above, the present application discloses a solution. It should be noted that although the present application is primarily intended for an LTM scenario, it is also applicable to other non-LTM scenarios. Furthermore, adopting a unified design solution for different scenarios (such as other non-LTM scenarios comprising, but not limited to, a capacity enhancement system, a near-field communication system, unlicensed band communication, Internet of Things (IoT), an ultra-reliable low-latency communication network (URLLC), and vehicle for everything) also helps reduce hardware complexity and cost.

[0361] Embodiment 4 illustrates 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 the first communication device 410 and the second communication device 450 communicating with each other on the access network.

[0362] The first communication device 410 comprises 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 transmitting device / receiving device 418 and an antenna 420.

[0363] The second communication device 450 comprises a controller / processor 459, a memory 460, a data source 467, a transmission processor 468, a reception processor 456, a multi-antenna transmission processor 457, a multi-antenna reception processor 458, a transmission device / receiving device 454 and an antenna 452.

[0364] In the transmission from the first communication device 410 to the second communication device 450, in the first communication device 410, the data packets from the upper layer of the main network are provided to the controller / processor 475. The controller / processor 475 implements the L2 functionality. In DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical channels and transport channels, and allocation of radio resources from the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second communication device 450. The transmission processor 416 and the processor of Petition 870250112631, dated 08 / 12 / 2025, page 42 / 94 37 / 83 multiantenna transmission 471 implements several signal processing functions for L1 (i.e., the physical layer). The transmission processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) in the second communication device 450 and the mapping of signal groupings based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-Quadature Amplitude Modulation (M-QAM)). The multiantenna transmission processor 471 performs digital spatial pre-coding of the encoded and modulated symbols, which comprises codebook-based pre-coding and non-codebook-based pre-coding and beamforming processing, to generate one or more parallel streams.The transmission processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., pilot) in the time domain and / or frequency domain, and then uses the Inverse Fast Fourier Transform (IFFT) to generate a physical channel that carries the multicarrier symbol stream in the time domain. The multiantenna transmission processor 471 then performs analog transmission precoding / beamforming operations on the multicarrier symbol stream in the time domain. Each transmission device 418 converts the baseband multicarrier symbol stream provided by the multiantenna transmission processor 471 into a radio frequency stream and then provides it to different antennas 420.

[0365] In the transmission from the first communication device 410 to the second communication device 450, in the second communication device 450, each receiving device 454 receives a signal through its corresponding antenna 452. Each receiving device 454 retrieves modulated information for the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream to provide it to the receiving processor 456. The receiving processor 456 Petition 870250112631, dated 08 / 12 / 2025, page 43 / 94 The 38 / 83 and the 458 multi-antenna receiving processor implement several L1 signal processing functions. The 458 multi-antenna receiving processor performs analog receive pre-coding / beamforming operations on the baseband multicarrier symbol stream from the 454 receiving device. The 456 receiving processor uses the Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream from the time domain to the frequency domain after the analog receive pre-coding / beamforming operations.In the frequency domain, the physical layer data signals and reference signals are demultiplexed by the receiving processor 456, where the reference signals are used for channel estimation, and the data signals undergo multi-antenna detection in the multi-antenna receiving processor 458 to recover any parallel streams destined for the second communication device 450. The symbols in each parallel stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then decodes and deinterlaces the soft decisions to recover upper-layer data and control signals transmitted by the first 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 L2 functions.The 459 controller / processor may be associated with a 460 memory that stores program codes and data. The 460 memory may be referred to as a computer-readable medium. In DL, the 459 controller / processor provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to retrieve data packets from the upper layer of the core network.

The 459 controller / processor is also responsible for error detection using acknowledgment (ACK) and / or negative acknowledgment (NACK) protocols.

[0366] In the transmission from the second communication device 450 to the first communication device 410, in the second communication device 450, the 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 L2. Similar to the transmission function in the first communication device 410, as described for the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical channels and transport channels based on the wireless resource allocation of the first communication device 410, thus implementing L2 functions for the user plane and the control plane. The controller / processor 459 is also responsible for HARQ operations, lost packet retransmission, and signaling to the first communication device 410.The 468 transmission processor performs modulation mapping and channel coding processing, and the 457 multi-antenna transmission processor performs multi-antenna digital spatial precoding, including codebook-based and non-codebook-based precoding and beamforming processing. The 468 transmission processor modulates the resulting parallel streams into multi-carrier / single-carrier symbol streams. These streams undergo analog precoding / beamforming operations in the 457 multi-antenna transmission processor before being supplied to different 452 antennas via the 454 transmission device. Each 454 transmission device first converts baseband symbol streams supplied by the 457 multi-antenna transmission processor into radio frequency symbol streams and then supplies the radio frequency symbol streams to the 452 antenna.

[0367] In the transmission from the second communication device 450 to the first communication device 410, the function in the first communication device 410 is similar to the reception function in the second device.

The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 function. The controller / processor 475 implements the L2 functions.

The memory 476 may be referred to as a computer-readable medium.The 475 controller / processor provides multiplexing between transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the second 450 communication device.
