Description

Method and apparatus in a node used for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for feedback information in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on New Radio interface (NR) technology (or fine Generation, 5G) is decided over 72 sessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network), and standardization Work on NR is started over WI (Work Item) where NR passes through 75 sessions of 3GPP RAN.

For the rapidly evolving Vehicle-to-evolution (V2X) service, the 3GPP initiated standard formulation and research work under the NR framework. Currently, 3GPP has completed the work of making requirements for the 5G V2X service and has written the standard TS 22.886. The 3GPP defines a 4-large application scenario group (Use Case Groups) for the 5G V2X service, including: automatic queuing Driving (Vehicles platform), Extended sensing (Extended Sensors), semi/full automatic Driving (Advanced Driving) and Remote Driving (Remote Driving). NR-based V2X technical research has been initiated over 3GPP RAN #80 congress.

Disclosure of Invention

In the study of NR V2X, studies on QoS (Quality of Service) and Priority (Priority) are an important aspect. The 3GPP has agreed to display the priority indicating the user message in SCI (Sidelink Control Information). Priority information of a user message is related to other information (such as MCS (Modulation and Coding Scheme), AL (Aggregation Level), etc.) indicated by signaling, and it is a considerable problem to fully utilize the priority information to reduce signaling overhead.

In view of the above, the present application discloses a solution. It should be noted that, in the description of the present application, only the NR V2X scenario is taken as a typical application scenario or example; the application is also applicable to other scenes than the NR V2X scene facing similar problems, and can also achieve the technical effect similar to the NR V2X scene. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to the NR V2X scenario) also helps to reduce hardware complexity and cost.

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3. Fig. 3 is a schematic diagram illustrating an embodiment of radio protocol architecture for theuser plane 350 and thecontrol plane 300, fig. 3 showing the radio protocol architecture for the first communication node device (UE, RSU in gbb or V2X) and the second communication node device (gbb, RSU in UE or V2X), or thecontrol plane 300 between two UEs, in 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. The L1 layer will be referred to herein asPHY 301. Layer 2(L2 layer) 305 is above the PHY301 and is responsible for the link between the first and second communication node devices and the two UEs through thePHY 301. TheL2 layer 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, which terminate at the second communication node device. ThePDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. ThePDCP sublayer 304 also provides security by ciphering data packets and provides handoff support between second communication node devices to the first communication node device. TheRLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ. TheMAC sublayer 302 provides multiplexing between logical and transport channels. TheMAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell between the first communication node devices. TheMAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control)sublayer 306 in layer 3 (layer L3) in theControl plane 300 is responsible for obtaining Radio resources (i.e. Radio bearers) and configuring the lower layers using RRC signaling between the second communication node device and the first communication node device. The radio protocol architecture of theuser plane 350 comprises layer 1(L1 layer) and layer 2(L2 layer), the radio protocol architecture in theuser plane 350 for the first and second communication node devices being substantially the same for thephysical layer 351, thePDCP sublayer 354 in theL2 layer 355, theRLC sublayer 353 in theL2 layer 355 and the MAC sublayer 352 in theL2 layer 355 as the corresponding layers and sublayers in thecontrol plane 300, but thePDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. TheL2 layer 355 in theuser plane 350 further includes an SDAP (Service Data Adaptation Protocol)sublayer 356, and theSDAP sublayer 356 is responsible for mapping between QoS streams and Data Radio Bearers (DRBs) to support diversity of services. Although not shown, the first communication node device may have several upper layers above theL2 layer 355, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, server, etc.).

Fig. 4 is a block diagram of afirst communication device 410 and asecond communication device 450 communicating with each other in an access network.

Thefirst communications device 410 includes a controller/processor 475, amemory 476, a receiveprocessor 470, a transmitprocessor 416, a multiple antenna receiveprocessor 472, a multiple antenna transmitprocessor 471, a transmitter/receiver 418, and anantenna 420.

Thesecond communications device 450 includes a controller/processor 459, amemory 460, adata source 467, a transmitprocessor 468, a receiveprocessor 456, a multi-antenna transmitprocessor 457, a multi-antenna receiveprocessor 458, a transmitter/receiver 454, and anantenna 452.

In the transmission from thefirst communication device 410 to thesecond communication device 450, at thefirst 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 layer L2. In the DL, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to thesecond communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to thesecond communication device 450. The transmitprocessor 416 and the multi-antenna transmitprocessor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmitprocessor 416 implements coding and interleaving to facilitate Forward Error Correction (FEC) at thesecond 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), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmitprocessor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook based precoding, and beamforming processing on the coded and modulated symbols to generate one or more parallel streams. Transmitprocessor 416 then maps each parallel stream to subcarriers, multiplexes the modulated symbols with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate the physical channels carrying the time-domain multicarrier symbol streams. The multi-antenna transmitprocessor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Eachtransmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitprocessor 471 into a radio frequency stream that is then provided to adifferent antenna 420.

In a transmission from thefirst communications device 410 to thesecond communications device 450, at thesecond communications device 450, eachreceiver 454 receives a signal through itsrespective antenna 452. Eachreceiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to a receiveprocessor 456. Receiveprocessor 456 and multi-antenna receiveprocessor 458 implement the various signal processing functions of the L1 layer. A multi-antenna receiveprocessor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from thereceiver 454. Receiveprocessor 456 converts the baseband multicarrier symbol stream after the receive analog precoding/beamforming operation 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 to be used for channel estimation are demultiplexed by the receiveprocessor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receiveprocessor 458 to recover any parallel streams destined for thesecond communication device 450. The symbols on each parallel stream are demodulated and recovered in a receiveprocessor 456 and soft decisions are generated. The receiveprocessor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by thefirst 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 functionality of the L2 layer. The controller/processor 459 may be associated with amemory 460 that stores program codes and data.Memory 460 may be referred to as a computer-readable medium. In the DL, 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 packet is then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing. The controller/processor 459 is also responsible for error detection using an Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocol to support HARQ operations.

In a transmission from thesecond communications device 450 to thefirst communications device 410, adata source 467 is used at thesecond communications device 450 to provide upper layer data packets to a controller/processor 459.Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at thefirst communications apparatus 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 thefirst communications apparatus 410, implementing L2 layer functions for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to saidfirst communications device 410. A transmitprocessor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmitprocessor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the resulting parallel streams are then modulated by the transmitprocessor 468 into multi-carrier/single-carrier symbol streams, subjected to analog precoding/beamforming in the multi-antenna transmitprocessor 457, and provided todifferent antennas 452 via atransmitter 454. Eachtransmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmitprocessor 457 into a radio frequency symbol stream and provides the radio frequency symbol stream to theantenna 452.

In a transmission from thesecond communication device 450 to thefirst communication device 410, the functionality at thefirst communication device 410 is similar to the receiving functionality at thesecond communication device 450 described in the transmission from thefirst communication device 410 to thesecond communication device 450. Eachreceiver 418 receives an rf signal through itsrespective antenna 420, converts the received rf signal to a baseband signal, and provides the baseband signal to a multi-antenna receiveprocessor 472 and a receiveprocessor 470. The receiveprocessor 470 and the multiple antenna receiveprocessor 472 collectively implement the functionality of the L1 layer. Controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with amemory 476 that stores program codes and data.Memory 476 may be referred to as a computer-readable medium. The controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from thesecond communication device 450.
