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 related to a Sidelink (Sidelink) 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 multiple application scenarios, research on New Radio interface (NR) technology (or Fifth Generation, 5G) is decided on 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 bunions, and Work on NR is started on WI (Work Item) that has passed NR on 3GPP RAN #75 bunions.
The 3GPP has also started to initiate standards development and research work under the NR framework for the rapidly evolving Vehicle-to-evolution (V2X) service. The 3GPP has completed the work of making the requirements for the 5G V2X service and has written the standard TS 22.886. The 3GPP identified and defined a 4 major Use Case Group (Use Case Group) 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 at 3GPP RAN #80 congress, and the Pathloss of the transmitting and receiving ends of the V2X pair was agreed at the RAN 12019 first ad hoc conference as a reference for the transmit power of V2X.
Disclosure of Invention
In the NR V2X system, a resource location of a PSCCH (Physical Sidelink Control Channel)/PSCCH (Physical Sidelink Shared Channel) corresponding to a PSCCH (Physical Sidelink Shared Channel) is implicitly associated with the PSCCH/PSCCH. At least one PSFCH corresponds to one PSCCH/PSCCH. Generally, the RX UE may adjust the PSFCH transmit power according to the PL (path loss), and no matter how far the RX UE is from the TX UE (Transmission User Equipment) or the base station, the target receive power of the PSFCH received by the TX UE or the base station from the RX UE is equal, so as to avoid that a near-far effect is not generated when multiple RX UEs feed back simultaneously in a CDM (Code Division Multiplexing) mode. However, this would cause the RX UE far away to fail to reach the target received power even if transmitting at a higher power, which is likely to exceed the maximum transmit power, so that the RX UE far away would have to forego transmitting PSFCH; in addition, transmitting with greater power by a farther RX UE may also cause stronger interference to UEs in the vicinity of the RX UE.
In view of the above problems, the present application discloses a PSFCH power control scheme, which effectively solves the PSFCH transmission problem for farther RX UEs in the NR V2X system. It should be noted that, in case of no conflict, the embodiments and features of the embodiments in the user equipment of the present application may be applied to the base station, and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict. Further, although the present application was originally intended for SL (Sidelink), the present application can also be used for UL (Uplink). Further, although the present application was originally directed to single carrier communication, the present application can also be applied to multicarrier communication. Further, although the present application was originally directed to single antenna communication, the present application can also be applied to multi-antenna communication. Further, although the original intention of the present application is directed to the V2X scenario, the present application is also applicable to the communication scenarios between the terminal and the base station, between the terminal and the relay, and between the relay and the base station, and achieves the technical effects in the similar V2X scenario. Furthermore, adopting a unified solution for different scenarios (including but not limited to V2X scenario and terminal to base station communication scenario) also helps to reduce hardware complexity and cost.

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 as PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the first and second communication node devices and the two UEs through PHY 301.

Example 4
Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.
The first communications device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multiple antenna receive processor 472, a multiple antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.
The second communications 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.
In the transmission from the first communication device 410 to the second communication device 450, at the first 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 transmissions from the first communications device 410 to the first communications 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 second communications device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and 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) at the second communication device 450 and mapping of signal constellation 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, including codebook-based precoding and non-codebook based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes 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 transmit processor 471 then performs analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.
In a transmission from the first communications device 410 to the second communications device 450, at the second communications device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. Receive processor 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 receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communications 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 a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In transmissions from the first communications device 410 to the second communications device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer 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.
In a transmission from the second communications device 450 to the first communications device 410, a data source 467 is used at the second 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 the first communications apparatus 410 described in the transmission from the first communications apparatus 410 to the second communications apparatus 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, implementing L2 layer functions for the user plane and control plane. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to said first communications device 410. A transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmit processor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmit processor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to different antennas 452 via a transmitter 454 after analog precoding/beamforming in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and 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 functionality at the first communication device 410 is similar to the receiving functionality at 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 an rf signal through its respective antenna 420, converts the received rf signal to 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 multiple antenna receive processor 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 a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In transmissions from the second communications device 450 to the first communications device 410, 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 the UE 450. Upper layer data packets from the controller/processor 475 may be provided to a core network.
