Description

A method and device used in a node for wireless communication Technical Field

The present application relates to a transmission method and device in a wireless communication system, and in particular to a transmission method and device for wireless signals in a wireless communication system supporting a cellular network.

Background Art

In future wireless communication systems, the number of mobile terminals will grow exponentially, which will bring higher system capacity requirements. By deploying multiple sites (including base stations, TRPs (Transmit-Receive Points), relays, reconfigurable smart metasurfaces, etc.) at different locations in a wider geographical range, and forming larger-scale MIMO (Multiple-Input Multiple-Output) clusters at multiple sites and one or more antenna channels at each site, the spectrum efficiency can be significantly improved. In addition, different levels of intelligent interaction and intelligent collaboration are carried out between sites on demand: for basic simple services, multiple sites carry out simple information interaction and coordinate resource allocation scheduling, beamforming and other processes; for enhanced complex services, multiple sites collaborate deeply, carry out abundant information interaction, and effectively transform interference sources into useful signals. Through intelligent interaction and intelligent collaboration, on the one hand, interference is effectively eliminated and the signal reception quality is enhanced; on the other hand, coverage is effectively enhanced, the user's sense of boundary is eliminated, and a truly borderless user experience is provided for wireless networks.

In addition, Reconfigurable Intelligent Surface (RIS) has been widely studied as a candidate technology for 6G due to its unique low cost, low energy consumption, programmability, and easy deployment. It is an artificial electromagnetic surface structure with programmable electromagnetic properties, which contains a large number of independent low-cost passive subwavelength resonant units. Each RIS unit has independent electromagnetic wave control capabilities, and the response of each unit to wireless signals, such as phase, amplitude, polarization, etc., can be controlled by changing the parameters and spatial distribution of the RIS unit. Through the mutual superposition of the wireless response signals of a large number of RIS units, specific beam propagation characteristics are formed on a macro scale, thereby forming a flexible and controllable shaped beam, achieving the effect of eliminating coverage blind spots, enhancing edge coverage, and increasing the rank of multi-stream transmission.

Summary of the invention

How to determine the scrambling sequence of the physical channel and/or the RS (Reference signal) sequence of the DMRS (Demodulation reference signal) of the physical channel is a key issue.

Example 4

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 a first communication device 410 and a second communication device 450 communicating with each other in an access network.

The first 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 .

The second communication device 450 includes a controller/processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter/receiver 454 and an antenna 452.

In transmission from the first communication device 410 to the second communication device 450, at the first 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 DL, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources to 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 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 450, as well as constellation mapping 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 coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing to generate one or more parallel The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time domain and/or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding/beamforming operation 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.

In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through 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 and provides it 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 receiving analog precoding/beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding/beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any parallel stream destined for the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then decodes and deinterleaves the soft decisions to recover the 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 functions of the L2 layer. The controller/processor 459 may be associated with a memory 460 storing program codes and data. The memory 460 may be referred to as a computer-readable medium. In DL (DownLink, downlink), the controller/processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the 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 L3 for L3 processing. The controller/processor 459 is also responsible for error detection using confirmation (ACK) and/or negative confirmation (NACK) protocols to support HARQ operations.

In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a 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 the L2 layer. Similar to the transmission function at the first communication device 410 described in DL, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, and implements L2 layer functions for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated parallel stream into a multi-carrier/single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding/beamforming operations in the multi-antenna transmit processor 457. 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.

In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the reception function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with a memory 476 that stores program codes and data. The memory 476 can be referred to as a computer-readable medium. The controller/processor 475 provides demultiplexing between transmission and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 450. The upper layer data packets from the controller/processor 475 can be provided to the core network. The controller/processor 475 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.

The RIS 490 may be controlled by the first communication device 410 and/or the second communication device 450 to change channel implementation in a controlled manner, improve channel diversity, and provide robustness to channel blocking/fading, and the first communication device 410 or the second communication device 450 may be referred to as a control node of the RIS 490. At least one of the transmit processor 416, receive processor 470, and controller/processor 475 of the first communication device 410 may be configured to perform various aspects in conjunction with the controller 491 of the RIS 490, or at least one of the transmit processor 468, receive processor 456, and controller/processor 459 of the second communication device 450 may be configured to perform various aspects in conjunction with the controller 491 of the RIS 490.

The first communication device 410 and/or the second communication device 450 use the RIS 490 to perform communication, sensing and/or positioning functions. The information of the RIS 490 can be known to the network based on network planning, and the base station can provide the location of the RIS 490 and other RIS 490 information to other nodes (e.g., terminals in a cellular cell). For example, the base station can transmit the information of the RIS 490 in system information. Each terminal in the coverage area of the cellular cell can receive the system information to discover the existence, location, capabilities, or other information about the RIS 490.

In transmission where the first communication device 410 and/or the second communication device 450 uses the RIS 490 for communication, at the RIS 490, a plurality of resonant units form a RIS surface 492, receiving a downlink signal from the first communication device 410, or receiving an uplink signal from the second communication device 450, and each resonant unit can adjust (e.g., apply a phase shift to directionally reflect the received signal) the corresponding received signal. The controller 491 can configure the phase or amplitude change by applying a precoding weight to each resonant unit so that the RIS 490 can reradiate the output beam in different directions given a specific input beam.

In some cases, when the RIS 490 operates passively to merely reflect or refract a beam from a transmitter to a receiver, the RIS 490 can be used as a near-passive device, operating without significant power consumption. In some cases, the reflection or refraction direction can be controlled by a control node or network controller.

In transmission from a control node and the RIS 490, in the DL, at the RIS 490, the controller 491 may receive a signal from the control node and further process the received signal (e.g., digitize the received signal). In the UL, at the RIS 490, information/data from the controller 491 is sent or provided to the control node in response to information from the control node or data updates of the RIS 490.
