Description

Method and apparatus in a node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus related to channel state information in wireless communication.

Background

Orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) waveform technology is widely used in wireless communication systems, such as 4G long term evolution (Long Term Evolution, LTE) and 5G New Radio (NR) systems. OFDM is well resistant to frequency selective fading and is easily combined with multi-antenna technology, so that good performance can be achieved in a broadband wireless communication system. The main drawback of OFDM is to have a high Peak-to-Average Power Ratio (PAPR). In practical applications, significant signal distortion occurs when the power of the input signal is high due to the nonlinearity of the rf power amplifier. To avoid such distortion, it is often necessary to power back-off the OFDM signal so that the OFDM signal operates as much as possible in the linear region of the power amplifier. Thus, for a particular power amplifier, the OFDM signal will lose some transmit power. The peak-to-average ratio of a single carrier waveform (e.g., DFT-spread OFDM, DFT-s-OFDM) is relatively low compared to OFDM, and for the same power amplifier, the single carrier signal may be reduced by a power back-off value, resulting in higher transmit power. Therefore, the single carrier waveform has important value in the scene of limited coverage, and DFT-s-OFDM waveform technology is used for the uplink of LTE and NR.

Disclosure of Invention

In wireless communication systems such as LTE and NR, multi-antenna technology (MIMO) is a key feature, and configuration, measurement, and reporting of channel state information (Channel State Information, CSI) are an important enabling technology for MIMO. In current NR and LTE systems, the downlink transmission uses an OFDM waveform, so the configuration, measurement and reporting of CSI are all based on the OFDM waveform. On the other hand, different waveform technologies (for example, OFDM waveform and DFT-s-OFDM waveform) are suitable for different application scenarios, and the use of multiple waveform technologies in downlink transmission is beneficial to improving system performance, which is one of the technical directions of system evolution such as NR and LTE. If downlink transmission adopts various waveform technologies, how to configure, measure and report CSI becomes a problem to be solved.

In view of the above, the present application discloses a solution. In the description of the above problem, the present application is also applicable to other link types, such as sidelink (sidelink) transmission and backhaul (backhaul) transmission, to achieve similar technical effects. Similarly, the OFDM waveform and DFT-s-OFDM waveform are also taken as an example, and the present application is also applicable to other waveforms, such as Cyclic Prefix-Single carrier (CP-SC) and filter bank multi-carrier (Fliter Bank Multi Carrier, FBMC), to achieve similar technical effects. In addition, the adoption of unified solutions for different scenarios (including but not limited to downlink transmission, sidelink transmission, backhaul link transmission; OFDM waveform, DFT-s-OFDM waveform, CP-SC waveform, FBMC waveform) also helps to reduce hardware complexity and cost.

Fig. 4 is a block diagram of a first communication device 410 and a second communication device 450 in communication 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 the transmission from the first communication device 410 to the second communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the first communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the first 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 second communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450, 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 first communication device 410 to the second communication device 450, each receiver 454 receives a signal at the second 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 second communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. A receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were 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 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium.

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 second communication device 450 to the first communication device 410, a data source 467 is used at the second 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 first communication device 410 described in the transmission from the first communication device 410 to the second 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 first 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 second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving 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 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.
