Description

[Technical Field]

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and more specifically, to a solution and apparatus for channel measurement and reporting in a wireless communication system. [Background technology]

[0002] In existing NR (New Radio) systems, spectral resources are statically divided into FDD (Frequency Division Duplication) and TDD (Time Division Duplication) spectra. However, in the case of TDD spectra, both base stations and user equipment operate in half-duplex mode. While this half-duplex mode can avoid self-interference and mitigate the effects of cross-link interference, it also results in reduced resource utilization and increased latency. Considering these issues, supporting flexible duplex mode in either TDD or FDD spectra is a possible solution. At the 3GPP RAN (Radio Access Networks) 1#103e meeting, research work on duplex technology was agreed upon. In this work, subband non-overlapping full-duplex (SBFD) was proposed, meaning that base station devices are supported to perform transmit and receive simultaneously on two subbands. Communication in this mode will suffer from serious interference, including self-interference and cross-link interference. [Overview of the project]

[0003] In existing systems, in order to send CSI (Channel Status Information) reporting, the UE needs to obtain channel measurements for the CSI reporting based on RS (Reference Signal) resources, and one critical issue is how to determine when to send RS resources for channel measurements.

[0338] Embodiment 3, as shown in Figure 3, is a schematic diagram of one embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application. Figure 3 is a schematic diagram illustrating one embodiment of the wireless protocol architecture of the user plane 350 and the control plane 300. Figure 3 shows the relationship between a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X), or between the three layers of Layer 1, Layer 2, and Layer 3. This shows the radio protocol architecture of the control plane 300 used between two UEs. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. The L1 layer is referred to herein as PHY 301. Layer 2 (L2 layer) 305 sits above PHY 301 and is responsible for the link between the first and second communication node devices, or between the two UEs. The L2 layer 305 includes the MAC (Media Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which are terminated at the second communication node device. The PDCP sublayer 304 performs multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support between the first and second communication node devices. The RLC sublayer 303 compensates for out-of-order reception due to HARQ by providing segmentation and reconstruction of upper-layer data packets, retransmission of lost data packets, and reordering of data packets. The MAC sublayer 302 provides multiplexing between logical channels and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a single cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operation. The RRC (Radio Resource Control) sublayer 306 at Layer 3 (L3 layer) in the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second and first communication node devices. The radio protocol architecture of the 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 the user plane 350 is substantially 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, except that the PDCP sublayer 354 also provides header compression of upper-layer data packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptive Protocol) sublayer 356, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not shown in the figure, the first communication node device may have several higher layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the network-side P-GW and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0358] Embodiment 4 Embodiment 4, as shown in Figure 4, illustrates a schematic diagram of a first communication device and a second communication device according to one embodiment of the present application. Figure 4 is a block diagram of the first communication device 410 and the second communication device 450 communicating with each other within an access network.

[0359] The first communication device 410 comprises a controller / processor 475, memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitting / receiving device 418, and an antenna 420.

[0360] The second communication device 450 comprises a controller / processor 459, memory 460, data source 467, transmit processor 468, receive processor 456, multi-antenna transmit processor 457, multi-antenna receive processor 458, transmit / receive device 454, and antenna 452.

[0361] In transmission from the first communication device 410 to the second communication device 450, the first communication device 410 provides the controller / processor 475 with upper-layer data packets from the core network. The controller / processor 475 implements L2 layer functions. In DL, the controller / processor 475 performs header compression, encryption, packet splitting and reordering, and logical chat based on various priority metrics. The controller / processor 475 provides multiplexing between the channel and the transport channel, as well as radio resource allocation, to the second communication device 450. The controller / processor 475 is also responsible for HARQ operation and retransmission of lost packets, as well as 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). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) in the second communication device 450, as well as 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), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 generates one or more parallel streams by performing digital space precoding, including codebook-based and non-codebook-based precoding, as well as beamforming processing on coded and modulated symbols. Next, the transmit processor 416 maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses the Fast Fourier Inverse Transform (IFFT) to generate a physical channel to carry the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs send analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmit device 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, which is then provided to the different antennas 420.

[0362] In transmission from the first communication device 410 to the second communication device 450, each receiving device 454 in the second communication device 450 receives the signal via its corresponding antenna 452. Each receiving device 454 reconstructs the information modulated on the radio frequency carrier, converts the radio frequency stream into a baseband multicarrier symbol stream, and provides the baseband multicarrier symbol stream to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receive analog precoding / beamforming operation on the baseband multicarrier symbol stream from the receiving device 454. The receiving processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream from the time domain to the frequency domain after the receive analog precoding / beamforming operation. In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receiving processor 456. The reference signal is used for channel estimation, and the data signal is reconstructed after multi-antenna detection in the multi-antenna receiving processor 458 to reconstruct any parallel streams destined for the second communication device 450. Symbols on each parallel stream are demodulated and reconstructed in the receiving processor 456 to generate a soft decision. The receiving processor 456 then decodes and deinterleaves the soft decision to reconstruct 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 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 DL (downlink) phase, the controller / processor 459 provides demultiplexing between the transport channel and logical channel, packet reassembly, decoding, header decompression, and control signal processing to reconstruct upper-layer data packets from the core network.Next, the upper-layer data packets are provided to all protocol layers above the L2 layer. For L3 processing, various control signals may also be provided to L3. The controller / processor 459 also provides acknowledgments (ACKs) and / or to support HARQ operation. It is responsible for error detection using the Negative Response (NACK) protocol.

[0363] In transmission from the second communication device 450 to the first communication device 410, the second communication device 450 uses a data source 467 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 forwarding functions in the first communication device 410 described in DL, the controller / processor 459 implements header compression, encryption, packet splitting and reordering, as well as multiplexing between logical and transport channels, based on the radio resource allocation of the first communication device 410, and implements L2 layer functions of the user plane and control plane. The controller / processor 459 is also responsible for HARQ operation and retransmission of lost packets, as well as signaling to the first communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, as well as beamforming processing. Next, the transmitting processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via transmitting devices 454 after analog precoding / beamforming operations in the multi-antenna transmitting processor 457. Each transmitting device 454 first converts the baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, which is then provided to the antenna 452.

[0364] In transmission from the second communication device 450 to the first communication device 410, the functions of the first communication device 410 are the same as the receiving functions of the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiving device 418 receives a radio frequency signal via its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal 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 functions of the L1 layer. The controller / processor 475 implements the functions of the L2 layer. 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 a computer-readable medium. The controller / processor 475 recovers upper-layer data packets from the second communication device 450 by providing demultiplexing between the transport channel and logical channel, packet reassembly, decoding, header decompression, and control signal processing. The upper-layer data packets from the controller / processor 475 can be provided to the core network. The controller / processor 475 is also responsible for error detection using the ACK and / or NACK protocols to support HARQ operation.
