Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a method and apparatus for triggering and indicating measurement reports. Background Art

[0002] With the continuous development of wireless communication, the requirements for mobility, transmission delay, and system capacity are getting higher and higher. The 3GPP RAN (Radio Access Network) #94e meeting decided to study L1 (Layer 1) / L2 (Layer 2) triggered mobility (LTM) in the "Further NR mobility enhancements" work item (WI) of the "NR (New Radio) mobility further enhancements" research project.

[0003] To enhance the measurement reporting process of LTM, 3GPP will introduce event-triggered L1 measurement reports in Release 19, including aspects such as configuration methods, event definitions, and filtering methods. Summary of the Invention

[0004] The inventors found that in the existing protocol, the UE performs measurements based on measurement configurations and reports the measurement results, and the network makes mobility decisions based on the reported measurement results. With the expansion of communication scenarios, the purposes of triggering events are diversified. When multiple-purpose triggering events are configured for a cell, based on the existing measurement reports, it may cause the network to confuse the purposes of measurement reports, which is not conducive to subsequent decisions. Therefore, it is necessary to enhance the triggering indication of measurement reports. In particular but not limited to, when the UE is configured with triggering events for LTM cell handover and triggering events for LTM early uplink synchronization, it is necessary to enhance how to report information to assist the network in subsequent decisions.

[0005] In view of the above problems, the present application provides a solution. In the above problem description, the NR system is taken as an example. The present application is also applicable to scenarios of systems such as LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), or future 6G, achieving technical effects similar to those of the NR system. Further, although specific implementation manners are given for 3GPP systems in the present application, the present application can also be used in scenarios of non-3GPP systems, achieving technical effects similar to those of 3GPP systems. Further, adopting a unified design solution for different scenarios also helps to reduce hardware complexity and cost. Further, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 interface, achieving technical effects similar to those of the Uu air interface. Further, although the original intention of the present application is for LTM, the present application can also be used for conditional LTM, or continuous LTM, or SCPAC, or CHO, or CPC, etc., achieving technical effects similar to those of LTM. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between the terminal and the relay, and between the relay and the base station, achieving technical effects similar to those in the terminal-to-base station scenario. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the communication scenario of IAB (Integrated Access and Backhaul), achieving technical effects similar to those in the terminal-to-base station scenario. Further, although the original intention of the present application is for the terrestrial network (TN) scenario, the present application is also equally applicable to the communication scenario of the non-terrestrial network (NTN), achieving technical effects similar to those in the TN scenario. In addition, adopting a unified solution for different scenarios also helps to reduce hardware complexity and cost.

[0367] Example 4

[0368] Example 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in Figure 4 shown. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 that communicate with each other in an access network.

[0369] 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 an antenna 452.

[0370] 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 an antenna 420.

[0371] In the transmission from the second communication device 410 to the first communication device 450, at the second 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 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, encryption, 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 L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal constellations 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 on the encoded 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 reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations 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 a radio frequency stream, and then provides it to different antennas 420.

[0372] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream and provides it to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier 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 receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 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. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission 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, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0373] 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 described at the second communication device 410 in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and 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. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after passing through analog precoding / beamforming operations in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0374] 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 described at the first communication device 450 in the transmission from the second communication device 410 to the first communication device 450.
