Description

TECHNICAL FIELD

[0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a method and device for determining full duplex resources. BACKGROUND

[0002] The existing NR(New Radio) system divides the spectrum resources into FDD(Frequency Division Duplexing) spectrum and TDD(Time Division Duplexing) spectrum. For the TDD spectrum, the base station and the user equipment (User Equipment, UE) both work in the half duplex mode. This half duplex mode reduces the resource utilization and increases the delay. In view of these problems, the 3GPP(the 3rd Generation Partnership Project) RAN(Radio Access Network) 1#103e meeting passed the research project (Study Item, SI) of "Study on Evolution of NR Duplex Operation". In the research project, the subband non-overlapping full duplex (SBFD) is proposed, which supports the base station device to simultaneously transmit and receive on two subbands. In the 3GPP Release 19, the WI(Work Item) for the subband non-overlapping full duplex is further started. SUMMARY

[0003] The inventor finds through research that, in order to perform full duplex, how the UE determines the time-frequency resources available for full duplex is a problem that needs to be studied.

Further, the unified design scheme for different scenarios also helps to reduce hardware complexity and cost. Further, although the present application gives specific embodiments for SBFD, the present application can also be used in other full duplex scenarios, and similar technical effects of SBFD are obtained. Further, although the present application gives specific embodiments for network-side full duplex, the present application can also be used in scenarios of UE-side full duplex, and similar technical effects of network-side full duplex are obtained. Further, although the present application gives specific embodiments for TDD-based full duplex, the present application can also be used in FDD-based full duplex scenarios, and similar technical effects of TDD-based full duplex are obtained. Further, although the present application gives specific embodiments for full duplex based on licensed spectrum, the present application can also be used in full duplex based on unlicensed spectrum scenarios, and similar technical effects of full duplex based on licensed spectrum are obtained. Further, although the present application is initially intended for Uu air interface, the present application can also be used for PC5 interface, and similar technical effects of Uu air interface are obtained. Further, although the present application is initially intended for a terminal and base station scenario, the present application is also applicable to V2X (Vehicle-to-Everything) scenarios, terminal and relay, and communication scenarios between relay and base station, and similar technical effects in the terminal and base station scenario are obtained. Further, although the present application is initially intended for a terminal and base station scenario, the present application is also applicable to IAB (Integrated Access and Backhaul) communication scenarios, and similar technical effects in the terminal and base station scenario are obtained. Further, although the present application is initially intended for a TN (Terrestrial Network) scenario, the present application is also applicable to NTN (Non-Terrestrial Network) communication scenarios, and similar technical effects in the TN scenario are obtained. In addition, the unified solution for different scenarios also helps to reduce hardware complexity and cost.

[0397] Example 4

[0398] Figure 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as described in Figure 4 Figure 4. Figure 4 Figure 4 shows a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0399] The first communication device 450 comprises 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 antennas 452.

[0400] The second communication device 410 comprises 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 antennas 420.

[0401] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets, and signaling to the first communication device 450. The transmit processor 416 and the multiple antenna transmit processor 471 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of coded bits to modulation symbols 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 multiple antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps to each spatial stream to the subcarriers, multiplexes the stream with reference signals (e.g., pilot) in the time and / or frequency domain, and then performs an inverse fast Fourier transform (IFFT) to generate a time-domain multicarrier symbol stream for the physical channel. The multiple antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 into a radio frequency stream, and then provides the radio frequency stream to the corresponding antenna 420.

[0402] In transmissions from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the recovered information at baseband, as a stream of symbols, to a receive processor 456. The receive processor 456 and a multiple access receiver processor 458 implement various signal processing functions of the Ll layer. The multiple access receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multiple access symbol streams from the receivers 454. The receive processor 456 converts the baseband multiple access symbol streams from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed from the received symbol streams by the receive processor 456, with the reference signals to be used for channel estimation and the data signals to be recovered after multiple access detection in the multiple access receiver processor 458 for any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and used to generate soft decisions. The receive processor 456 then decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to a controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer-readable medium. In transmissions from the second communication device 410 to the first communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals can also be provided to the L3 for L3 processing.

[0403] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper layer data packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implements L2 layer functionality for the user plane and control plane. The controller / processor 459 is also responsible for error detection, retransmission of lost packets, and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping, channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, and then the transmit processor 468 modulates the resulting spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 via transmitters 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency signal, and then provides the radio frequency signal to the antenna 452.

[0404] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive functions at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its respective antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal 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 functionality of the L1 layer. A controller / processor 475 implements the functionality of the L2 layer. The controller / processor 475 can be associated with a memory 476 that stores program codes and data. The memory 476 can be referred to as a computer readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer data packets from the controller / processor 475 can be provided to a core network.
