BACKGROUND
Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a method and device for radio signal transmission in a wireless communication system supporting cellular networks.

Related Art

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 existing NR systems, spectrum resources are statically divided into Frequency Division Duplexing (FDD) spectrum and Time Division Duplexing (TDD) spectrum. For TDD spectrum, both the base station and UE (i.e., User Equipment) operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the effects of Cross Link Interference (CLI), but it also brings problems such as reduced resource utilization and increased latency. In view of these problems, to support flexible duplex mode or variable link directions (Uplink, or Downlink, or Flexible ones) on the TDD spectrum or the FDD spectrum becomes a potential solution. In the 3GPP RAN #88e meeting and the 3GPP Rel-18 (also referred to as Release-18 or version 18) workshop, the support of more flexible duplex mode or full duplex mode in NR Rel-18 has been widely noticed and discussed, especially the Subband non-overlapping Full Duplex (SBFD) mode at the gNB (NR node B) end. Communication in this mode is subject to severe interference, including self-interference and CLI. To solve the interference problem, advanced interference cancellation techniques are required, including antenna isolation, beamforming, RF (Radio Frequency) level interference cancellation and digital interference cancellation.

SUMMARY

In the existing standards, due to the PUSCH (i.e., Physical Uplink Shared CHannel) frequency-domain resource allocation type 1 and partial formats of PUCCH (i.e., Physical Uplink Control CHannel), the allocation in the frequency domain is done for continuous Resource Blocks (RBs), which needs to be discretized by frequency hopping to improve the anti-interference capability, reduce the probability of interception, and offer anti-fading support, so as to improve the communication quality. In SBFD scenarios, a PUSCH or PUCCH transmission may occupy both SBFD resources and non-SBFD resources, the interference environment varies with different resources, and the parameter configuration of uplink transmission may also be different, if the type of resources occupied by the signal is not taken into account for uplink frequency hopping transmission, the second-hop signal may be mapped into a SBFD slot for configuring resources outside the subband for uplink transmission, thus leading to uplink and downlink conflicts or resulting in fragmentation of uplink resources. Therefore, the hopping frequencies of PUSCH and PUCCH also need to be enhanced.

To address the above problem, the present application provides a solution. It should be noted that although the original intent of this application is for SBFD scenarios, this application can also be applied to other non-SBFD scenarios; further, the adoption of a unified design scheme for different scenarios (e.g., other non-SBFD scenarios including, but not limited to, capacity augmentation systems, systems for near field communications, unlicensed spectrum communications, Internet of Things (IoT), Ultra Reliable Low Latency Communication (URLLC) networks, Vehicle-to-everything (V2X), etc.) also helps to reduce hardware complexity and cost. It should be noted that if no conflict is incurred, embodiments in any node in the present application and the characteristics of the embodiments are also applicable to any other node, and vice versa. What's more, the embodiments in the present application and the characteristics in the embodiments can be arbitrarily combined if there is no conflict.

Embodiment 3

Embodiment 3 illustrates a schematic diagram of an example of a radio protocol architecture of a user plane and a control plane according to the present application, as shown in FIG. 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 communication node (UE, or Road Side Unit/RSU in Vehicle to Everything (V2X), vehicle-mounted equipment or vehicle-mounted communication module) and a second node (gNB, UE, or RSU in V2X, vehicle-mounted equipment or vehicle-mounted communication module), or between two UEs is represented by three layers, i.e., Layer 1 (L1), Layer 2 (L2) and Layer 3 (L3). The L1 is the lowest layer which performs various signal processing functions of PHY (i.e., PHYsical layer). The L1 is called PHY 301 in the present application. The L2 305 is above the PHY 301, and is in charge of the link between a first node and a second node as well as between two UEs via the PHY 301. The L2 305 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 these sublayers terminate at the second nodes. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 provides security by encrypting packets and also support for inter-cell handover of the first communication node between second communication nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (HARQ). The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel. The MAC sublayer 302 is also responsible for allocating between first communication nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer 302 is also in charge of HARQ operation. In the control plane 300, the RRC sublayer 306 in the L3 layer is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the second communication node and the first communication node. The radio protocol architecture in the user plane 350 comprises the L1 layer and the L2 layer. In the user plane 350, the radio protocol architecture used for the first communication node and the second communication node in a PHY layer 351, a PDCP sublayer 354 of the L2 layer 355, an RLC sublayer 353 of the L2 layer 355 and a MAC sublayer 352 of the L2 layer 355 is almost the same as the radio protocol architecture used for corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression used for higher-layer packet to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also comprises a Service Data Adaptation Protocol (SDAP) sublayer 356, which is in charge of the mapping between QoS streams and a Data Radio Bearer (DRB), so as to support diversified traffics. Although not described in FIG. 3, the first communication node may comprise several higher layers above the L2 355, such as a network layer (i.e., Internet Protocol/IP layer) terminated at a P-GW 213 of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.).

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to one embodiment of 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 in communication with each other 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 a core network is provided to the controller/processor 475. The controller/processor 475 provides functions of the L2 layer. In DL, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, 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 responsible for HARQ operation, 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 and the mapping of signal clusters corresponding to each modulation scheme (i.e., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-PSK, and M-Quadrature Amplitude Modulation (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 to a subcarrier. The modulated 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. 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 provide various signal processing functions of the L1. 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 Fast Fourier Transform (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 provides functions of the L2. 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 transmission, the controller/processor 459 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 core network. The higher-layer packet is later provided to all protocol layers above the L2. Or various control signals can be provided to the L3 for processing. The controller/processor 459 also performs error detection using ACKnowledgement (ACK) and/or Negative ACKnowledgement (NACK) protocols 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 used to provide a higher layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2. 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 for the first communication device 410 so as to provide the L2 functions used for the user plane and the control plane. The controller/processor 459 is responsible for HARQ operation, 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 codebook-based precoding and non-codebook-based precoding, 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 firstly converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the 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. The controller/processor 475 provides functions of the L2. 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 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 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 can also perform error detection using ACK and/or NACK protocol to support HARQ operation.
