Description

A method and apparatus in a communication node used for wireless communication

[0001] This application claims priority to the Chinese Patent Application No. 202410889525.9, filed on July 3, 2024, and titled “A method and apparatus in a communication node used for wireless communication”, and to the Chinese Patent Application No. 202410895769.8, filed on July 4, 2024, and titled “A method and apparatus in a communication node used for wireless communication”, both of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a method and apparatus for cancelling measurement reporting. BACKGROUND

[0003] With the continuous development of wireless communication, the requirements for mobility, transmission delay and system capacity are becoming higher and higher. At the 94e meeting of 3GPP RAN (Radio Access Network), it was decided to study L1 / L2 triggered mobility (LTM) in the “NR (New Radio) mobility further enhancement” research project (Work Item, WI).

[0004] To enhance the measurement reporting process of LTM, 3GPP will introduce event-triggered L1 measurement reporting in Rel-19, including configuration methods, event definitions, filtering methods, etc. SUMMARY

[0005] The inventors have found that in the existing LTM triggering mechanism, after LTM is configured, the UE triggers L1 measurement reporting according to the periodicity or event configured by the network. Since the measurement reporting needs to wait for valid uplink resources, the valid uplink resources depend on network configuration and channel quality of the serving cell. The measurement report may be invalid during the waiting for valid uplink resources due to channel changes and other factors, at which time reporting the original measurement report may cause resource waste and handover failure, so it is necessary to enhance the cancellation of measurement reporting.

[0006] To solve the above problems, the present application provides a solution. In the description of the above problems, the NR system is taken as an example, and the present application is also applicable to scenarios of systems such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) or future 6G, and similar technical effects of the NR system are obtained; further, although the present application gives specific embodiments for the 3GPP system, the present application can also be used in non-3GPP system scenarios to obtain similar technical effects of the 3GPP system. Further, the unified design scheme for different scenarios also helps to reduce hardware complexity and cost. Further, although the original intention of the present application is to target the Uu air interface, the present application can also be used for the PC5 interface to obtain similar technical effects of the Uu air interface. Further, although the original intention of the present application is to target the LTM, the present application can also be used for conditional LTM or continuous LTM or SCPAC or CHO or CPC, etc., to obtain similar technical effects of the LTM. Further, although the original intention of the present application is to target the terminal and base station scenario, the present application is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the communication scenario between the relay and the base station, and similar technical effects in the terminal and base station scenario are obtained. Further, although the original intention of the present application is to target the terminal and base station scenario, the present application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, and similar technical effects in the terminal and base station scenario are obtained. Further, although the original intention of the present application is to target the TN (Terrestrial Network) scenario, the present application is also applicable to the NTN (Non-Terrestrial Network) communication scenario, and similar technical effects in the TN scenario are obtained. In addition, the unified solution for different scenarios also helps to reduce hardware complexity and cost.

[0376] Embodiment 3

[0377] Embodiment 3 shows a diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in FIG. 3. FIG. 3 is a diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300, which shows three layers for the control plane 300: Layer 1, Layer 2, and Layer 3. Layer 1 (LI layer) is the lowest layer and implements various PHY (Physical layer) signal processing functions. The LI layer will be referred to as the PHY 301 herein. Layer 2 (L2 layer) 305 is above the PHY 301 and includes a MAC (Medium Access Control) sublayer 302, a RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encryption of data packets, and provides header compression. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and using RRC signaling to configure the lower layers. The radio protocol architecture for the user plane 350 includes Layer 1 (LI layer) and Layer 2 (L2 layer), which are generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The SDAP (Service Data Adaptation Protocol) sublayer 356 is also included in the L2 layer 355 in the user plane 350, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support diverse traffic.

[0391] Embodiment 4

[0392] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in FIG. 4. FIG. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0393] 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.

[0394] 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.

[0395] In transmissions 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. For transmissions 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 precoding of 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 a subcarrier, multiplexes the stream with reference signals (e.g., pilot signals), and then performs a Fast Fourier Transform (FFT) to generate a time-domain multicarrier symbol stream for the physical channel. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 then converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency (RF) stream, which is then provided to a respective antenna 420.

[0396] 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, 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 first 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.

[0397] 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.

[0398] 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.
