[0004] --Original application title: A method and apparatus used in a node for wireless communication Technical Field

[0005] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0006] In LTE systems, inter-cell handover is controlled by the base station based on UE (User Equipment) measurements. 3GPP (3rd Generation Partner Project) Release 15 largely follows the LTE mechanism for inter-cell handover. In NR (New Radio) systems, more application scenarios need to be supported. Some scenarios, such as URLLC (Ultra-Reliable and Low-Latency Communications), place high demands on latency and present new challenges to inter-cell handover.

[0007] In NR systems, Massive MIMO (Multiple Input Multiple Output) is an important technical feature. In Massive MIMO, multiple antennas use beamforming to form a narrow beam pointing in a specific direction to improve communication quality. The beam formed by multi-antenna beamforming is generally quite narrow, and the beams of the communicating parties need to be aligned for effective communication. Summary of the Invention

[0008] The inventors discovered through research that beam-based communication can negatively impact inter-cell handover, causing additional latency and the ping-pong effect. How to mitigate these negative impacts and further improve the performance of users at cell boundaries to meet the needs of various application scenarios is a problem that needs to be solved.

[0009] To address the aforementioned problems, this application discloses a solution. It should be noted that although the above description uses large-scale MIMO and beam-based communication scenarios as examples, this application is also applicable to other scenarios such as LTE multi-antenna systems, achieving similar technical effects to those in large-scale MIMO and beam-based communication scenarios. Furthermore, adopting a unified solution across different scenarios (including but not limited to large-scale MIMO, beam-based communication, and LTE multi-antenna systems) helps reduce hardware complexity and cost. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node, and vice versa. Unless otherwise specified, embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0010] As an example, the interpretation of the terminology in this application is based on the definition in the 3GPP specification protocol TS36 series.

[0013] As an example, the interpretation of terms in this application is based on the definitions in the IEEE (Institute of Electrical and Electronics Engineers) specification protocols.

[0014] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0015] Send a first signal, which indicates a first reference signal from M reference signals, where M is a positive integer greater than 1;

[0016] Receive the first signaling in the first resource block;

[0017] After the first moment, the spatial parameters of the target reference signal are used to monitor the first type of signaling in the first resource block subset;

[0018] Wherein, at least one of the M reference signals is sent by the first cell, which has not been added by the first node; the time domain resources occupied by the first signaling are used to determine the first time; the sender of the first reference signal is the target cell, and whether the target cell has been added by the first node is used to determine whether the target reference signal is the first reference signal.

[0019] As an example, the problems this application aims to solve include: how to reduce the latency caused by inter-cell handover and avoid service interruption. The above method solves this problem by having the UE measure reference signals from the local cell and neighboring cells, and determining whether to update the TCI (Transmission Configuration Indicator) state of the local cell's CORESET (Control Resource SET) based on the UE's feedback.

[0020] As an example, the features of the above method include: the M reference signals include reference signals from neighboring cells, and the first node determines the reference signal to be fed back to its own cell or the reference signal from a neighboring cell based on the measurement results.

[0021] As an example, the features of the above method include: the first resource block subset is associated with the CORESET configured in the current cell, and the first node determines whether to update the TCI status of the first resource block subset based on whether the feedback reference signal is a reference signal of the current cell or a reference signal of a neighboring cell.

[0022] As an example, the advantages of the above method include: enabling fast cross-cell beam handover, improving the performance of users at cell boundaries, and avoiding the resulting latency and potential service interruptions.

[0023] As an example, the advantages of the above method include: while using the beam of a neighboring cell selected by the UE to serve the UE, communication between the UE and the local cell is still maintained, thus ensuring service quality while avoiding the ping-pong effect.

The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0377] Example 4

[0378] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0379] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0380] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0381] 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 L2 layer functionality. In the L2 layer, 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 operation, 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and 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-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more parallel streams. Transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0382] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted over the physical channel by the first communication device 410. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2 (L2). The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0383] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0384] 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 into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[1070] As an example, the CRC of the first type of signaling is scrambled by RA (RandomAccess)-RNTI.

[1071] As an example, the blind detection refers to blind decoding, that is, receiving a signal and performing a decoding operation; if the decoding is determined to be correct based on the CRC bits, it is determined that a signaling of the first type has been detected; otherwise, it is determined that no signaling of the first type has been detected.

[1072] As an example, the blind detection refers to coherent detection, that is, performing coherent reception and measuring the energy of the signal obtained after coherent reception; if the energy of the signal obtained after coherent reception is greater than a first given threshold, it is determined that a first type of signaling has been detected; otherwise, it is determined that no first type of signaling has been detected.

[1088] As one embodiment, the first set of resource blocks is configured by the sender of the first reference signal.

[1089] As one example, the first resource block set is configured by the second cell.

[1097] As an example, M3 is not less than 2, and the M3 candidate resource block sets include a first candidate resource block set and a second candidate resource block set; any reference signal associated with the first cell among the M reference signals corresponds to the first candidate resource block set, and any reference signal associated with the second cell among the M reference signals corresponds to the second candidate resource block set.

[1356] Example 28

[1357] Example 28 illustrates a schematic diagram of the air interface resources occupied by a first signal according to an embodiment of this application; as shown in the attached diagram. Figure 28 As shown.

[1379] As an example, the second cell monitors the first signal in the third air interface resource.

[1380] As an example, the first cell monitors the first signal in the third air interface resource.
