Description

Method and device used in wireless communication nodes

Technical field

The present application relates to transmission methods and devices in wireless communication systems, in particular to wireless signal transmission methods and devices in wireless communication systems supporting cellular networks.

Background technique

Multi-antenna technology is a key technology in the 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system and NR (New Radio) system. Additional spatial degrees of freedom are obtained by configuring multiple antennas at communication nodes, such as base stations or UEs (User Equipment). Multiple antennas use beamforming to form beams pointing in a specific direction to improve communication quality. The degree of freedom provided by multiple antenna systems can be exploited to improve transmission reliability and/or throughput. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points, transmitting and receiving nodes)/panels (antenna panels), additional diversity gain can be obtained by utilizing the spatial differences between different TRPs/panels. In NRR(release)17, uplink transmission based on multiple beams/TRP/panel is supported to improve the reliability of uplink transmission. In R17, a UE can be configured with multiple SRS (Sounding Reference Signal) resource sets based on codebook (codebook) or non-codebook (non-codebook). Different SRS resource sets correspond to different beams/TRP/ panel, used to implement multi-beam/TRP/panel uplink transmission.

Contents of the invention

Uplink signals based on different SRS resource sets can occupy mutually orthogonal time domain resources, such as the approach in R17, or can also occupy overlapping time domain resources.

Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in the 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.

In transmission from the first communication device 410 to the second communication device 450, upper layer data packets from the core network are provided to the controller/processor 475 at the first communication device 410. 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 control of the second communication device 450 based on various priority metrics.

Transmit processor 416 and multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (ie, physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communications device 450, as well as 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)) constellation mapping. 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 streams. Transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (eg, a pilot) in the time and/or frequency domain, and then uses an inverse fast Fourier transform (IFFT ) to generate a physical channel carrying a stream of time-domain multi-carrier symbols. Then the multi-antenna transmit processor 471 performs transmit analog precoding/beamforming operations 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, which is then provided to a different antenna 420.

The controller/processor 459 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the first communications 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 beam forming processing, and then transmits The processor 468 modulates the generated parallel streams into multi-carrier/single-carrier symbol streams, which undergo analog precoding/beamforming operations in the multi-antenna transmit processor 457 and then are provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmission processor 457 into a radio frequency symbol stream, and then provides it to the antenna 452.
