technical field

The present application relates to a transmission method and device in a wireless communication system, in particular to a mobility transmission method and device.

Background technique

Traditional network controlled (Network Controlled) mobility includes cell level mobility (cell level) and beam level mobility (beam level), where cell level mobility depends on RRC (Radio Resource Control, Radio Resource Control) signaling, beam-level mobility does not involve RRC signaling. Before 3GPP (the 3rd Generation Partnership Project, third-generation partnership project) R16, beam-level mobility was only aimed at beam management (Beam Management) in a single cell. The 3GPPRAN#80 meeting decided to carry out the "Further enhancements on MIMO for NR" work item (WorkIterm, WI) to support multi-beam (multi-beam) operation (operation), aiming at Layer 1 (Layer 1, L1)/Layer 2 ( Layer 2, L2)-centric inter-cell mobility (L1/L2-centric inter-cell mobility) and inter-cell multiple TRP (multiple Transmit/Receive Point, mTRP) are enhanced.

Contents of the invention

In order to realize inter-cellL1/L2mobility or inter-cellmTRP, when UE (UserEquipment, user equipment) is in the serving cell, the network configures the radio parameters of another cell to the UE through RRC message, and the UE is within the coverage of the serving cell (Serving cell) , the TRP of another cell can be used for data transmission, and the other cell and the serving cell have different PCIs (Physical Cell Identifier, physical cell identifier). The inventor found through research that the existing configuration of reference signal resources used for radio link failure (RLF, Radio Link Failure) measurement may need to be redesigned. Aiming at the above problems, the present application provides a solution. Although the original intention of the above problem is for L1/L2mobility or mTRP; the present application is also applicable to, for example, Layer 3 handover or sidelink scenarios, and achieves similar technical effects. In addition, adopting a unified solution for different scenarios can also help reduce hardware complexity and cost.

The transmit processor 416 and the 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 communication device 410, and based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift Mapping of signal clusters for 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 spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with a reference signal (e.g., pilot) in the time and/or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate A physical channel that carries a time-domain multi-carrier symbol stream. Then the multi-antenna transmit processor 471 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 an RF stream, which is then provided to a different antenna 420 .

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 in the multi-antenna detection in the multi-antenna receiving processor 458. Any spatial stream for which the first communication device 450 is a destination. The symbols on each spatial stream are demodulated and recovered in receive processor 456 and soft decisions are generated.
