Description

A method and apparatus for use in a communication node for wireless communication Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a method and apparatus for acquiring broadcast information. Background Art

[0002] 5G (5th Generation) is a next-generation broadband mobile communications technology featuring high speed, low latency, and massive connections. Its three main application scenarios include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (uRLLC), and massive machine-type communications (mMTC). To meet the diverse needs of 5G applications, 5G's key performance indicators are becoming more diverse, with high speed, low latency, and massive connections becoming 5G's most prominent features. With the continuous introduction of new technologies and new demands, the future of 6G (6th Generation) wireless communications will see even more diverse scenarios.

[0003] Typically, reconfigurable intelligent surfaces (RIS) are considered key technologies for 5G-Advanced research and one of the core visions of 6G, due to their low cost, low energy consumption, programmability, ease of deployment, and high shaping gain achieved with larger antenna scales. RIS is an artificial electromagnetic surface structure with programmable electromagnetic properties. It contains a large number of independent, low-cost, passive subwavelength resonant units. By superimposing the wireless response signals from the reflective surfaces of a large number of RISs, specific beam propagation characteristics are formed on a macro scale, thereby forming a flexible and controllable shaped beam, eliminating coverage blind spots, enhancing edge coverage, and increasing the rank of multi-stream transmission. Furthermore, AI (Artificial Intelligence) or ML (Machine Learning), ISAC (Integrated Sensing and Communication), and NTN (Non-Terrestrial Network) will also become important evolutionary directions for 6G in the future.

[0004] Summary of the Invention

[0005] In the existing 5G NR system, during the cell search process, the UE (User Equipment) receives the SSB (Synchronization Signal Block, or SS / PBCH block) formed by the synchronization signal (SS), PBCH (Physical broadcast channel) and DM-RS (Demodulation reference signal) of the PBCH, obtains the physical layer cell identity (PCI) from the synchronization signal, and obtains the parameters of the PDCCH (Physical downlink control channel) scheduling SIB1 (System Information Block 1) from the MIB (Master Information Block) and PBCH payload. The parameters of the PDCCH scheduling SIB1 include CORESET (Control resource set) #0 and searchSpaceZero. The calculation of CORESET #0 depends on the SSB index, the scrambling code sequence of the PDCCH scheduling SIB1, and the RS (Reference RS) of the DMRS of the PDCCH scheduling SIB1. The generation of at least one of the four: a reference signal (Signal) sequence, a scrambling sequence of a PDSCH (Physical downlink shared channel) carrying SIB1, and an RS sequence of a DMRS of the PDSCH carrying SIB1 depends on the PCI obtained through synchronization signal detection.

[0006] Through research, the inventors discovered that existing mechanisms for acquiring broadcast information suffer from shortcomings such as low cell search efficiency, long system information acquisition times, and poor energy conservation. These shortcomings make them difficult to meet the demands of future diverse wireless communication scenarios (especially but not limited to RIS). Therefore, it is necessary to enhance the mechanisms for acquiring broadcast information.

[0007] In response to the above problems, the present application provides a solution. In the description of the above problems, the RIS system is used as an example. The present application is also applicable to other scenarios for coverage enhancement systems, achieving technical effects similar to the RIS system; further, although the present application provides a specific implementation method for the downlink, the present application can also be used in scenarios such as the secondary link, achieving technical effects similar to the downlink. Furthermore, adopting a unified design solution 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, achieving technical effects similar to 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 the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the relay and the base station, achieving technical effects similar to those in the terminal and base station scenario. 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, achieving 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, achieving similar technical effects in the TN scenario. In addition, adopting a unified solution for different scenarios can also help reduce hardware complexity and cost.

FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the radio protocol architecture for the control plane 300 using three layers: Layer 1, Layer 2, and Layer 3.

The PDCP sublayer 304 also provides security by encrypting data packets and supports inter-zone mobility. 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 out-of-order reception due to HARQ (Hybrid Automatic Repeat Request).

[0582] The third communication device 490 includes at least one of a control component 491 , an information component 496 , or a memory 495 , and a reflective surface 492 .

[0583] The third communication device 490 includes a reflective surface 492 , and does not include any of the control component 491 , the information component 496 , and the memory 495 .

[0584] During transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to the controller / processor 475 at the second communication device 410. The controller / processor 475 implements L2 layer functionality. During 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), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming 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 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 multicarrier 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.

[0585] During 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 via 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, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The 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 multi-carrier symbol stream, after the receive analog precoding / beamforming operations, from the time domain to the frequency domain using a fast Fourier transform (FFT). In the frequency domain, the receive processor 456 demultiplexes the physical layer data signal and reference signal, where the reference signal is used for channel estimation. The data signal undergoes multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the 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 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 code and data. The memory 460 may be referred to as a computer-readable medium. During 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, and control signal processing to recover 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 the L3 layer for L3 processing.

[0586] During 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 the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functionality 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, implementing L2 layer functions for the user plane and control plane. 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 and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, the stream is provided to 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 RF symbol stream before providing it to the antenna 452.

[0587] During transmission from the first communications device 450 to the second communications device 410, the functionality at the second communications device 410 is similar to the reception functionality at the first communications device 450 described for transmission from the second communications device 410 to the first communications device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF 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 collectively implement L1 layer functionality. A controller / processor 475 implements L2 layer functionality. The controller / processor 475 may be associated with a memory 476 storing program codes and data. The memory 476 may be referred to as a computer-readable medium. During transmission from the first communications device 450 to the second communications 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. Upper layer packets from controller / processor 475 may be provided to the core network.

[0588] During transmission from the second communication device 410 to the first communication device 450, at the third communication device 490, the reflective surface 492 reflects / refracts the signal / channel / information from the second communication device 410. Alternatively, during transmission from the first communication device 450 to the second communication device 410, at the third communication device 490, the reflective surface 492 reflects / refracts the signal / channel / information from the first communication device 450. The reflective surface 492 is composed of a plurality of resonant elements, each of which can adjust (e.g., apply a phase shift to directionally reflect a received signal) a corresponding received signal. The control component 491 can configure phase or amplitude changes by applying precoding weights to each resonant element, enabling the third communication device 490 to reradiate an output beam in different directions given a particular input beam. In some cases, when the third communication device 490 operates passively, reflecting or refracting only a beam from a transmitter to a receiver, the third communication device 490 can function as a nearly passive device, operating without significant power consumption. In some cases, the reflection / refraction direction can be controlled by a control node or network controller. The third communication device 490 can be controlled by the first communication device 450 and / or the second communication device 410 to modify channel implementation in a controlled manner, improve channel diversity, and provide robustness to channel obstruction / fading. The first communication device 450 or the second communication device 410 can be referred to as a control node for the third communication device 490. At least one of the transmit processor 416, receive processor 470, and controller / processor 475 of the first communication device 450 can be configured to perform various aspects in conjunction with the information component 496 or controller component 491 of the third communication device 490. Alternatively, at least one of the transmit processor 468, receive processor 456, and controller / processor 459 of the second communication device 410 can be configured to perform various aspects in conjunction with the information component 496 or controller component 491 of the third communication device 490. The first communication device 450 and / or the second communication device 410 can also use the third communication device 490 to perform communication, sensing, and / or positioning functions. The information of the third communication device 490 may be known to the network based on network planning, and the base station may provide the location of the third communication device 490 and other information about the third communication device 490 to other nodes (e.g., terminals in a cellular cell). For example, the base station may transmit the information of the third communication device 490 in system information. Each terminal within the coverage of the cellular cell may receive the system information to discover the existence, location, capabilities, or other information about the third communication device 490.
