Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission scheme and apparatus related to Sidelink in wireless communication. Background Art

[0002] Since LTE (Long Term Evolution), 3GPP (3rd Generation Partnership Project) has been developing SL (Sidelink) as a direct communication method between users and completed the first NR SL (New Radio Sidelink) standard of "5G V2X with NR Sidelink" in Rel-16 (Release-16). In Rel-16, NR SL is mainly designed for V2X (Vehicle-To-Everything), but it can also be used for Public Safety.

[0003] However, due to time constraints, NR SL Rel-16 cannot fully support all the service requirements and working scenarios identified by 3GPP for 5G V2X. Therefore, 3GPP will study enhancing NR SL in Rel-17. Summary of the Invention

[0004] In an NR SL system, generally, the battery life of VRUs (Vulnerable road users) and PUEs (Pedestrian user equipments) is short, and the processing complexity is low. To save power, VRUs or PUEs often use random resource selection, periodic partial sensing, or continuous partial sensing to determine the time-frequency resources for transmitting signals. When a sensing user senses the time-frequency resources occupied by a neighboring VRU or PUE user, and the data priority of the sensing user is higher than that of the neighboring VRU or PUE, but since the VRU or PUE cannot perform channel sensing and thus cannot avoid interfering with neighboring users, the sensing user has to actively avoid the interfering time-frequency resources, resulting in an impact on the transmission performance of the sensing user.

[0005] In view of the above problems, the present application discloses a transmission method for sensing a user, thereby effectively avoiding the transmission performance of the sensed user. It should be noted that, without conflict, the embodiments in the user equipment of the present application and the features in the embodiments can be applied to the base station, and vice versa. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. Further, although the original intention of the present application is for SL, the present application can also be used for UL (Uplink). Further, although the original intention of the present application is for single-carrier communication, the present application can also be used for multi-carrier communication. Further, although the original intention of the present application is for single-antenna communication, the present application can also be used for multi-antenna communication. Further, although the original intention of the present application is for the V2X scenario, the present application is also applicable to the communication scenarios between the terminal and the base station, the terminal and the relay, and the relay and the base station, achieving similar technical effects in the V2X scenario. In addition, adopting a unified solution for different scenarios (including but not limited to the V2X scenario and the communication scenario between the terminal and the base station) helps to reduce the hardware complexity and cost.

[0006] It should be noted that the interpretation of the terms in the present application is based on the definitions in the 3GPP specification protocols TS36 series, TS37 series and TS38 series, but can also refer to the definitions in the IEEE (Institute of Electrical and Electronics Engineers) specification protocols.

[0401] Example 3

[0402] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to this application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3Show the radio protocol architecture of the control plane 300 for the first node device (UE or RSU in V2X, vehicle-mounted device or vehicle-mounted communication module) and the second node device (gNB, UE or RSU in V2X, vehicle-mounted device or vehicle-mounted communication module), or between two UEs, using 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. Layer 1 will be referred to as PHY 301 in this article. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first node device and the second node device, as well as between two UEs, through PHY 301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the second node device. The PDCP sublayer 304 provides data encryption and integrity protection, and the PDCP sublayer 304 also provides handover support for the first node device to the second node device. The RLC sublayer 303 provides segmentation and reassembly of data packets, retransmission of lost data packets through ARQ, and the RLC sublayer 303 also provides duplicate data packet detection and protocol error detection. The MAC sublayer 302 provides the mapping between logical and transport channels and the multiplexing of logical channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using the RRC signaling between the second node device and the first node device. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). For the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, the radio protocol architecture for the first node device and the second node device in the user plane 350 is generally the same as the corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression for the upper layer data packets to reduce the wireless transmission overhead. The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, and the SDAP sublayer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs, Data Radio Bearer) to support the diversity of services.Although not illustrated, the first node device may have several upper layers above the L2 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., a remote UE, a server, etc.).

[0413] Example 4

[0414] Example 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 shown. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0415] The first communication device 410 includes 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.

[0416] 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.

[0417] 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 the L2 layer. In the transmission from the first communication device 410 to the second communication 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 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., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal constellations 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 on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream and then provides it to a different antenna 420.

[0418] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The 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. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0419] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, the data source 467 is used to provide upper layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function 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 allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after passing through the analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to 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 then provides it to the antenna 452.

[0420] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receiving functions 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 into baseband signals, and provides the baseband signals to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The 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, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the UE 450. The upper layer data packets from the controller / processor 475 may be provided to the core network.
