The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a method and device of sidelink-related transmission in wireless communications.
Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 session to standardize the NR.
In response to rapidly growing Vehicle-to-Everything (V2X) traffic, 3GPP has started standards setting and research work under the framework of NR. Currently, 3GPP has completed planning work targeting 5G V2X requirements and has included these requirements into standard TS22.886, where 3GPP identifies and defines 4 major Use Case Groups, covering cases of Vehicles Platooning, supporting Extended Sensors, Advanced Driving and Remote Driving. At 3GPP RAN #80 Plenary Session, the technical Study Item (SI) of NR V2X was started.
A WI of NR R (release) 17 was approved at the 3GPP RAN #86 Plenary, including reference by the V2X system under FR2 band. In the FR2 band, there are two important means of guaranteeing performance, namely, massive MIMO and beam-based transmission. Multiple antennas form a narrow beam through beamforming, so that energy can be concentrated in a specific direction, thus enhancing the communication quality. Since the way of V2X resource occupation differs a lot from a Uu interface, the commonly used scheme of beam management or transmission for the Uu interface cannot be directly applied in the V2X system. To sum up, it is necessary to find out how to support beamforming in the V2X system, in view of that, the present disclosure disclosed a solution. It should be noted that although only V2X and beamforming-based transmission scenarios were stated above for example, this disclosure is also applicable to other scenarios such as cellular network and precoding-based transmissions, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios (including but not limited to V2X, cellular network, beamforming-based and precoding-based transmissions) contributes to the reduction of hardcore complexity and costs. If no conflict is incurred, the embodiments of a first node in the present disclosure and the characteristics of the embodiments can be applied to a second node, and vice versa. And the embodiments in the present disclosure and the characteristics of the embodiments can be arbitrarily combined if there is no conflict.
To ensure beam alignment between both sides of communication, the concept of beam management and beam-based channel measurement/feedback was introduced in NR R15 and R16. Resource occupation and Channel State Information (CSI) reporting in V2X are implemented quite differently from Uu interface, so the scheme of beam management generally used on the Uu interface is not directly applicable to the V2X system. Therefore, how to conduct beam management in the V2X system needs to be addressed, and for that, the present disclosure provides a solution. It should be noted that although only V2X and beamforming-based transmission scenarios were stated above for example, this disclosure is also applicable to other scenarios such as cellular network and precoding-based transmissions, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios (including but not limited to V2X, cellular network, beamforming-based and precoding-based transmissions) contributes to the reduction of hardcore complexity and costs. If no conflict is incurred, the embodiments of a first node in the present disclosure and the characteristics of the embodiments can be applied to a second node, and vice versa. And the embodiments in the present disclosure and the characteristics of the embodiments can be arbitrarily combined if there is no conflict.
Compared with the existing Long-term Evolution (LTE) V2X system, an NR V2X system has a distinctive feature of supporting unicast transmission and power control based on sidelink pathloss. Based on the conclusion drawn at the 3GPP RAN1 #97 conference, when a node is simultaneously configured with downlink pathloss-based power control and sidelink pathloss-based power control, the node will choose a smaller value of power values respectively acquired through the two methods. A significant technical feature of an NR system is support for beam-based transmission. Due to the beam directivity, how a node interferes with other nodes is highly dependent on the beam adopted. Therefore, how to control the interference to the cellular network in a beam-based V2X transmission becomes an issue, for which the present disclosure provides a solution. It should be noted that although only V2X and beam-based transmission scenarios were stated above for example, this disclosure is also applicable to other scenarios such as cellular network and non-beam transmissions, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios (including but not limited to V2X, cellular network, beam-based and non-beam transmissions) contributes to the reduction of hardcore complexity and costs. If no conflict is incurred, the embodiments of any node in the present disclosure and the characteristics of the embodiments can be applied to any other node, and vice versa. And the embodiments in the present disclosure and the characteristics of the embodiments can be arbitrarily combined if there is no conflict.

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to the present disclosure, as shown in
The first communication device 410 comprises 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.
The second communication device 450 comprises 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.
In a transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, a higher layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 implements the functionality of the L2 layer. In DL, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation of the second communication device 450 based on various priorities. The controller/processor 475 is also in charge of HARQ operation, a retransmission of a lost packet and a signaling to the second communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (i.e., PHY). The transmitting processor 416 performs coding and interleaving so as to ensure a Forward Error Correction (FEC) at the second communication device 450 side and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, which includes precoding based on codebook and precoding based on non-codebook, and beamforming processing on encoded and modulated signals to generate one or more parallel streams. The transmitting processor 416 then maps each parallel stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream, which is later provided to different antennas 420.
In a transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, and converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs reception analog precoding/beamforming on a baseband multicarrier symbol stream provided by the receiver 454. The receiving processor 456 converts the processed baseband multicarrier symbol stream from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any second communication device 450-targeted parallel stream. Symbols on each parallel stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted by the first communication device 410 on the physical channel. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of the L2 layer. The controller/processor 459 can be associated with a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In DL, the controller/processor 459 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing. The controller/processor 459 is also responsible for using ACK/NACK protocols in error detection as a way to support HARQ operation.
In a transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the first communication device 410 described in DL, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the first communication device 410 so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operation, a retransmission of a lost packet, and a signaling to the first communication device 410. The transmitting processor 468 performs modulation and mapping, as well as channel coding, and the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding, including precoding based on codebook and precoding based on non-codebook, and beamforming. The transmitting processor 468 then modulates generated parallel streams into multicarrier/single-carrier symbol streams. The modulated symbol streams, after being subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457, are provided from the transmitter 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.
In a transmission from the second communication device 450 to the first communication device 410, the function of the first communication device 410 is similar to the receiving function of the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal via a 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 provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be associated with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. The controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, control signal processing so as to recover a higher-layer packet from the second communication device 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network. The controller/processor 475 is also responsible for using ACK/NACK protocols in error detection as a way to support HARQ operation.
