Description

TECHNICAL FIELD

[0001] The present application relates to transmission methods and apparatuses in a wireless communication system, in particular to transmission schemes and apparatuses for beam management and link recovery. BACKGROUND

[0002] Traditional network controlled mobility includes cell level mobility and beam level mobility, wherein the cell level mobility depends on RRC signaling and the beam level mobility does not involve RRC signaling. Before the 3GPP R16, the beam level mobility is only for beam management in a single cell. In the 3GPP RAN#80 meeting, it is decided to carry out the work item (WI) of “Further enhancements on MIMO for NR”, to support multi-beam operation, and to enhance the L1 / L2-centric inter-cell mobility and inter-cell mTRP. SUMMARY

[0003] For the NR system, the 3GPP introduces a BFR (Beam Failure Recovery) mechanism, and a UE (User Equipment) evaluates according to a reference signal set belonging to a serving cell. If the evaluation result is worse than a predetermined threshold for a predetermined number of times, the BFR or a random access (RA) process is triggered. To realize inter-cell L1 / L2 mobility or inter-cell mTRP, when the UE is in a serving cell, the network configures at least one additional cell for the UE for the serving cell through an RRC message. The UE can use the TRP of the additional cell for data transmission within the coverage of the serving cell, and the additional cell and the serving cell have different PCIs (Physical Cell Identifiers).

[0004] In the existing NR system, the reference signal resource set for determining whether to trigger the BFR mechanism and the candidate reference signal resource set for selection are obtained through network side configuration, and the terminal device will not trigger the change of the two reference signal resource sets. In the beam management process, the terminal can implicitly inform the base station of its location under the coverage of which TRP according to the PCI associated with the reported reference signal resource, and the reference signal resource reported in the above beam management process can be applied to BFR to improve the efficiency of the BFR process.

[0005] To solve the above problems, the present application provides a solution. In the above problem description, the uu interface scenario is taken as an example; the present application is also applicable to, for example, the Sidelink scenario, and similar technical effects can be achieved in the uu interface scenario. In addition, using a unified solution in different scenarios can help reduce hardware complexity and cost. The present application is also applicable to other scenarios facing similar problems (for example, self-organizing networks, or scenarios where the central node is a non-base station node, or high-speed mobile scenarios, or for different application scenarios such as eMBB and URLLC, and similar technical effects can be achieved. In addition, using a unified solution in different scenarios (including but not limited to eMBB and URLLC scenarios) can help reduce hardware complexity and cost. In the case of no conflict, the embodiments in the first node device and the features in the embodiments can be applied to the second node device, and vice versa. In particular, the explanation of the terms (Terminology), nouns, functions, and variables in the present application (if not specially specified) can refer to the definitions in the 3GPP specification protocol TS (Technical Specification) 36 series, TS 38 series, and TS 37 series.

[0375] Example 4

[0376] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown inFigure 4 The first communication device 450 and the second communication device 410 are in communication with each other and with one or more other base stations 430 via a set of base stations 430 and a set of access networks 440. Figure 4 FIG. 1 shows a block diagram of the first communication device 450 and the second communication device 410 in communication over an access network.

[0377] The first 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 antennas 452.

[0378] The second 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 antennas 420.

[0379] In the transmission from the second communication device 410 to the first communication device 450, upper layer packets from a core network are provided to the controller / processor 475 at the second communication device 410. The controller / processor 475 implements functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets, and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of coded and modulated symbols onto resource elements (REs) for transmission. The multi-antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a set of subcarriers for transmission, multiplexes the spatial streams with reference signals (e.g., pilot signals), and then performs a Fast Fourier Transform (FFT) to generate time domain output streams. The multi-antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time domain output streams. Each transmitter 418 then converts the baseband output streams into analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to generate a modulated signal suitable for transmission, which is then provided to a corresponding antenna 420.

[0380] ​In transmissions from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the recovered information at baseband as a stream of symbols to a receive processor 456. The receive processor 456 and a multiple access receiver processor 458 implement various signal processing functions of the Ll layer. The multiple access receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multiple access symbol streams from the receivers 454. The receive processor 456 converts the baseband multiple access symbol streams 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 are demultiplexed from the received symbol streams by the receive processor 456, with the reference signals to be used for channel estimation and the data signals to be recovered after multiple access detection in the multiple access receiver processor 458 for any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and used to generate soft decisions. The receive processor 456 then decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second 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 functions of the L2 layer. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer-readable medium. In transmissions from the second communication device 410 to the second communication device 450, 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 data packets are then provided to all protocol layers above the L2 layer. Various control signals can also be provided to the L3 for L3 processing.

[0381] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper layer data packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implements L2 layer functionality for the user plane and control plane. The controller / processor 459 is also responsible for error detection, retransmission of lost packets, and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping, channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, and then the transmit processor 468 modulates the resulting spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 via transmitters 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 signal, and then provides the radio frequency signal to the antenna 452.

[0382] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive functions at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its respective antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal 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 functionality of the L1 layer. A controller / processor 475 implements the functionality of the L2 layer. 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. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer data packets from the controller / processor 475 can be provided to a core network.
