Description

Method and apparatus in a node used 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 method and apparatus for a wireless signal in a wireless communication system supporting a cellular network.

Background

In an LTE (Long-term Evolution) system, inter-cell Handover (Handover) is controlled by a base station based on measurements of UEs (User equipments). The mechanism in LTE is basically followed for inter-cell handover in 3GPP (3rd Generation Partner Project) R (Release) 15. In NR (New Radio) systems, more application scenarios need to be supported, and some application scenarios, such as URLLC (Ultra-Reliable and Low Latency Communications), place high demands on Latency, and also place New challenges on inter-cell handover.

In the NR system, large-scale (Massive) MIMO (Multiple Input Multiple Output) is an important technical feature. In large-scale MIMO, multiple antennas form a narrow beam pointing to a specific direction by beamforming to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the beams of both communication parties need to be aligned for effective communication.

Disclosure of Invention

The inventors have found through research that beam-based communication can negatively affect inter-cell handover, such as additional delay and ping-pong effects. How to reduce these negative effects and further improve the performance of cell border users to meet the requirements of various application scenarios is a problem to be solved.

In view of the above, the present application discloses a solution. It should be noted that although the above description uses a cellular system and a multi-antenna system as examples, the present application is also applicable to other scenarios such as V2X (Vehicle-to-event) or D2D (Device-to-Device) systems and single-antenna systems, and achieves similar technical effects in the cellular system and the multi-antenna system. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to cellular systems, V2X systems, D2D systems, multi-antenna systems, and single-antenna systems) also helps to reduce hardware complexity and cost.

Layer 1(L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY 301.

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 fig. 4. Fig. 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 communications device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multiple antenna receive processor 472, a multiple antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

The second communications 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, 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 layer L2. In the DL, the 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 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, including codebook-based precoding and non-codebook based precoding, and beamforming processing on the coded and modulated symbols to generate one or more parallel streams. Transmit processor 416 then maps each parallel stream to subcarriers, multiplexes the modulated symbols with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate the physical channels carrying the time-domain multicarrier symbol streams. 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 multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.

In a transmission from the first communications device 410 to the second communications device 450, at the second communications device 450, each receiver 454 receives a signal 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 multi-carrier symbol stream that is provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of 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. Receive processor 456 converts the baseband multicarrier symbol stream after the receive 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 signals and the reference signals to be used for channel estimation are demultiplexed by the receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any parallel streams destined for the second communication device 450. The symbols on each parallel stream are demodulated and recovered in a 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 first communication device 410 on the physical channel. The upper layer data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements the functionality 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. In the DL, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer packet is 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 an Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocol to support HARQ operations.

In a transmission from the second communications device 450 to the first communications device 410, a data source 467 is used at the second communications device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer.
