Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission scheme and apparatus for flexible transmission direction configuration in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to conduct research on the New Radio (NR) (or 5G) new air interface technology. At the 75th plenary session of 3GPP RAN, the WI (Work Item) of the New Radio (NR) new air interface technology was passed, and the standardization work of NR began. At the 86th plenary session of 3GPP RAN, it was decided to start the SI (Study Item) and WI (Work Item) of NR Rel-17, and it is expected to initiate the SI and WI of NR Rel-18 at the 94th e plenary session of 3GPP RAN.

[0003] In the new air interface technology, enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC) are three main application scenarios. In the NR Rel-16 system, compared with the LTE (Long-Term Evolution) and LTE-A (enhanced Long-Term Evolution) frame structures, one main difference is that the symbols in a time slot can be configured as Downlink, Uplink, and Flexible. For the symbols configured as "Flexible", the terminal will receive downlink on these symbols, and these symbols can also be used for uplink scheduling. The above method is more flexible than the LTE and LTE-A systems. Summary of the Invention

[0004] In the existing NR system, the base station can dynamically indicate the QCL (Quasi Co-located) relationship adopted by the scheduled PDSCH (Physical Downlink Shared Channel) through the TCI (Transmission Configuration Indication) field in the DCI (Downlink control information). However, when the end moments of the scheduled PDSCH and DCI are too close in the time domain, resulting in the terminal not having enough time to adjust the beam direction, the terminal will determine the QCL relationship of the current PDSCH according to the QCL relationship adopted by the CORESET (Control Resource Set) with the smallest controlResourceSetId in the nearest Slot. The problem that the terminal does not have enough time to adjust the beam direction needs to be reconsidered and designed in the working scenario supporting flexible duplex modes.

[0005] Regarding the configuration problem of link directions in the flexible duplex mode, this application discloses a solution. It should be noted that in the description of this application, the flexible duplex mode is only taken as a typical application scenario or example; this application is also equally applicable to other scenarios facing similar problems, such as scenarios where the link direction changes, or other scenarios supporting multi-level configured transmission directions, or scenarios with base stations or user equipment with stronger capabilities, such as scenarios supporting full-duplex in the same frequency band, or for different application scenarios, such as eMBB and URLLC, similar technical effects can also be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to scenarios of eMBB and URLLC) helps to reduce the hardware complexity and cost. Without conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa. In particular, the explanations of the terms, nouns, functions, and variables in this application (if not specifically stated) can refer to the definitions in the 3GPP specification protocols TS (Technical Specification) series 36, TS38 series, and TS37 series.

[0203] Example 3

[0204] Embodiment 3 shows a schematic 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 the appendix Figure 3 as shown. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3Show the radio protocol architecture of the control plane 300 for a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X) using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. Layer 1 will be referred to as PHY 301 in this text. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first communication node device and the second communication node device through PHY 301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets. The PDCP sublayer 304 also provides handover support for the first communication node device to the second communication node device. 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 disordered reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations.

The SDAP sub-layer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services.

[0230] Example 4

[0231] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in the appendix Figure 4 as follows. 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.

[0232] The first 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.

[0233] The second communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0234] In a 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 a 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 to 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 transmitting processor 416 and the multi-antenna transmitting processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmitting processor 416 implements coding 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 transmitting processor 471 performs digital spatial precoding on 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 transmitting 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 time-domain multi-carrier symbol streams. Subsequently, the multi-antenna transmitting processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol streams. Each transmitter 418 converts the baseband multi-carrier symbol streams provided by the multi-antenna transmitting processor 471 into radio frequency streams, and then provides them to different antennas 420.

[0235] 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 that is provided 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 is recovered in the multi-antenna receive processor 458 after multi-antenna detection for any spatial stream destined for the first communication device 450. 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 second 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.

[0236] 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 transmission 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 both 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. 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.

[0237] 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 reception functions described at the first communication device 450 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 corresponding 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 jointly implement the functions of the L1 layer. A 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 a computer-readable medium.
