CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of Chinese Patent Application 202210735692.9, filed on Jun. 27, 2022, the full disclosure of which is incorporated herein by reference.

BACKGROUND
Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a sidelink-related transmission scheme and device in wireless communications.

Related Art

Starting from Long Term Evolution (LTE), 3rd Generation Partner Project (3GPP) has been developing sidelink (SL) as a direct communication method between users, and has completed a first New Radio (NR) SL standard of “5G V2X with NR Sidelink” in Release-16 (Rel-16). In Rel-16, the NR SL is mainly designed for Vehicle-To-Everything (V2X), but it can also used for Public Safety. With the further enhancement of the NR SL, Rel-17 has introduced power saving schemes such as periodic-based partial sensing (PBPS), continuous partial sensing (CPS), random selection, and discontinuous reception (DRX), as well as various inter UE coordination schemes to provide more reliable channel resources.

In order to meet commercial application scenarios, the industry has put forward new demands for V2X, comprising higher data throughput and support for new carrier frequency. Therefore, at 3GPP RAN-#94e meeting, a Work Item Description (WID) RP-213678 for the evolution of NR SL was approved, which officially starts the standardization work of NR V2X Rel-18.

SUMMARY

According to a work plan in RP-213678, NR Rel-18 needs to support SL Carrier aggregation (CA) technology, and carrier components adopted by each User Equipment (UE) may be different. While in the existing NR Rel-16/17 system, data transmitted by a user on a PSSCH needs to receive a corresponding HARQ feedback in a same SL resource pool (RP) where the PSSCH is located. When two users adopt different carrier components (CCs) to transmit SL data, it may lead to peer users not having corresponding carrier components to execute a HARQ feedback, resulting in a decrease in the reliability of SL transmission.

In response to the above issues, the present application discloses a resource mapping method to effectively feed back data of multiple resource pools. It should be noted that the embodiments in a User Equipment (UE) in the present application and characteristics of the embodiments may be applied to a base station if no conflict is incurred, and vice versa. And the embodiments in the present application and the characteristics in the embodiments can be arbitrarily combined if there is no conflict. Though originally targeted at SL, the present application is also applicable to uplink (UL). Though originally targeted at single-carrier communications, the present application is also applicable to multicarrier communications. Though originally targeted at single-antenna communications, the present application is also applicable to multi-antenna communications. Besides, the present application is not only targeted at scenarios of V2X scenarios, but also at communication scenarios between terminals and base stations, terminals and relays as well as relays and base stations, where similar technical effect can be achieved. Additionally, the adoption of a unified solution for various scenarios, including but not limited to V2X scenarios and communication scenarios between terminals and base stations, contributes to the reduction of hardware complexity and costs.

It should be noted that interpretations of the terminology in the present application refer to definitions given in the 3GPP TS36 series, TS37 series, TS38 series, as well as definitions given in Institute of Electrical and Electronics Engineers (IEEE) protocol specifications.

Embodiment 3

FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a control plane 300 between a first node (UE or RSU in V2X, vehicle equipment or On-Board Communication Unit) and a second node (gNB, UE or RSU in V2X, vehicle equipment or On-Board Communication Unit), or between two UEs is represented by three layers, which are respectively layer 1, layer 2 and layer 3. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present application. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between the first node and the second node, and between two UEs via the PHY 301. The L2305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second nodes. The PDCP sublayer 304 provides data encryption and integrity protection and provides support for handover of a first node between second nodes.

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device in the present application, as shown in FIG. 4. FIG. 4 is a block diagram of a first communication device 410 in communication with a second communication device 450 in an access network.

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 the core network is provided to a controller/processor 475. The controller/processor 475 provides a function of the L2 layer. In the transmission from the first communication device 410 to the first communication device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resources allocation to the second communication device 450 based on various priorities. The controller/processor 475 is also responsible for 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 (that is, PHY). The transmitting processor 416 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the second communication device 450, and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more spatial streams. The transmitting processor 416 then maps each spatial 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 multi-carrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multi-carrier 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. Each radio frequency stream 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, 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 receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver 454. The receiving processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming 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 the second communication device-targeted spatial stream. Symbols on each spatial 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 on the physical channel by the first communication node 410. 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 connected to a memory 460 that stores program code and data. The memory 460 can be called 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 a transport channel and a logical channel, packet reassembling, decryption, 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.

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 the transmission from the first communication device 410 to the second communication device 450, 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 resources allocation 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 retransmission of a lost packet, and a signaling to the first communication device 410. The transmitting processor 468 performs modulation mapping and channel coding. The multi-antenna transmitting processor 457 implements digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, as well as beamforming. Following that, the generated spatial streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor 468, and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457 and provided from the transmitters 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 the 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 multi-antenna receiving processor 472 collectively provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be connected with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In the transmission from the second communication device 450 to the first communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the UE 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network.
