filing date of the original application: 10/25/2019

Number of the original application: 201911023666.8

-The name of the invention of the original application: method and apparatus in a node 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

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet the different performance requirements of multiple application scenarios, a New air interface technology (NR) study is decided on the 3GPP (3 rd Generation Partner Project, third Generation partnership project) RAN (Radio Access Network ) #72 full-time, and a standardization Work for NR is started on the 3GPP RAN #75 full-time with the WI (Work Item) of NR.

For the rapidly evolving internet of vehicles (V2X) service, 3GPP has also begun to initiate standard formulation and research work under the NR framework. The 3GPP has completed the requirement formulation work for the 5g v2x service at present, and writes it into the standard TS 22.886. The 3GPP identifies and defines a 4 Use Case Group (Use Case Group) for 5g v2x services, comprising: auto-queuing Driving (Vehicles Platnooning), support Extended sensing (Extended sensing), semi/full automatic Driving (ADVANCED DRIVING) and Remote Driving (Remote Driving). NR-based V2X technology studies have been initiated at 3gpp ran#80, and agree on the Pathloss for the transmitting and receiving ends of the V2X pair as a reference for the transmit power of V2X at RAN12019 for the first ad hoc conference.

Disclosure of Invention

In the NR V2X system, a resource location of PSFCH (PHYSICAL SIDELINK Feedback Channel ) corresponding to a PSCCH (PHYSICAL SIDELINK Control Channel, physical sidelink shared Channel)/PSSCH (PHYSICAL SIDELINK SHARED CHANNEL ) is implicitly associated with the PSCCH/PSSCH. So that at least one PSFCH corresponds to one PSCCH/PSSCH. In general, the RX UE adjusts PSFCH the transmit power according to PL (Pathloss), and no matter how far the RX UE is from the TX UE (Transmission User Equipment, transmitting user equipment) or the base station, the target receive power of PSFCH from the RX UE is received by the TX UE or the base station, so that near-far effect is avoided when multiple RX UEs feed back simultaneously in CDM (Code Division Multiplexing ) mode. However, this will cause the far RX UE to fail to reach the target received power even though it is transmitting with a larger power, and most likely the maximum transmit power is exceeded, so that the far RX UE has to discard the transmission PSFCH; in addition, transmitting a far RX UE at a higher power may also cause stronger interference to UEs in the vicinity of the RX UE.

In view of the above problems, the application discloses a PSFCH power control scheme, which effectively solves the PSFCH transmission problem for far RX UE in an NR V2X system. It should be noted that embodiments of the user equipment and features of embodiments of the present application may be applied to a base station and vice versa without conflict. The embodiments of the application and the features of the embodiments may be combined with each other arbitrarily without conflict. Further, although the present application is initially directed to SL (Sidelink ), the present application can also be used for UL (Uplink). Further, while the present application is primarily directed to single carrier communications, the present application can also be used for multi-carrier communications. Further, while the present application is primarily directed to single antenna communications, the present application can also be used for multiple antenna communications. Further, although the present application is initially directed to a V2X scenario, the present application is also applicable to a communication scenario between a terminal and a base station, between a terminal and a relay, and between a relay and a base station, to achieve similar technical effects in a V2X scenario. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to V2X scenarios and communication scenarios of terminals with base stations) also helps to reduce hardware complexity and cost.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 410 and a second communication device 450 in communication with each other in an access network.

The first communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

The second communication 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, upper layer data packets from the core network are provided to a controller/processor 475 at the first communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the first communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450, as well as mapping of signal clusters 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 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, 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 a physical channel carrying the time domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In a transmission from the first communication device 410 to the second communication device 450, each receiver 454 receives a signal at the second communication device 450 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 multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for 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. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the 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 signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. A receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the first communication device 410 on the physical channel. 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 codes and data. Memory 460 may be referred to as a computer-readable medium. In the transmission from the first 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. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In the transmission from the second communication device 450 to the first communication device 410, a data source 467 is used at the second communication 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 functions at the first communication device 410 described in the transmission from the first communication device 410 to the second 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 allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the different antennas 452 via the 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 provides it to an antenna 452.

In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the transmission from the second communication device 450 to the first communication device 410, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network.
