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

In existing New Radio (NR) systems, spectrum resources are 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. Such Half Duplex Mode avoids self-interference and reduces the influence of Cross Link interference, but it also brings about a reduction of resource utilization ratio and a longer delay. 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 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #88e meeting and the 3GPP Release-18 (also referred to as R-18) workshop, the support of more flexible duplex mode or full duplex mode in NR R-18 has been widely noticed and discussed, especially the SubBand non-overlapping Full Duplex (SBFD) mode at the gNB (NR node B) end. In this mode, the same symbol will be used for uplink in a portion of the frequency resources and for downlink in the other portion of the frequency resources, so that resource utilization is improved and delay is reduced.

SUMMARY

Inventors have found through the research that how to determine the search space sets being linked is a key problem.

To address the above problem, the present application provides a solution. It is to be noted that in the description of the present application, only the more flexible duplex mode, full duplex mode and SBFD mode are used as examples, and the present application can be applied to other duplex mode scenarios as well, and further, for different scenarios (including, but not limited to, the more flexible duplex mode, the full duplex mode, the SBFD mode, the half-duplex mode, the conventional duplex mode, the network energy-saving mode, the non-energy-saving mode, etc.) Adopting a unified design scheme 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 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 side and the constellation mapping corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and 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 into 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 452. 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 perform signal processing functions of the L1 layer. 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 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 layer. The controller/processor 459 can be associated with the memory 460 that stores program code and data; the memory 460 may be called a computer readable medium. In DownLink (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 layer. Or various control signals can be provided to the L3 for processing. The controller/processor 459 is also in charge of using ACK and/or NACK protocols for error detection 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 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 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 layer 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 precoding based on codebook and precoding based on non-codebook, 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 radio frequency 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 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be associated with the memory 476 that stores program code and data; the memory 476 may 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 protocols to support HARQ operation.
