Description

Method and apparatus related to PUCCH in a node for wireless communication

[0001] The present application claims priority from the Chinese patent application No. 202410737619.4 filed on June 7, 2024 with the State Intellectual Property Office, and titled "Method and apparatus related to PUCCH in a node for wireless communication", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, in particular, a method and apparatus related to PUCCH in a node for wireless communication. BACKGROUND

[0003] In the existing NR (New Radio) system, the spectrum resources are statically divided into FDD (Frequency Division Duplex) spectrum and TDD (Time Division Duplex) spectrum. For the TDD spectrum, the base station and the UE (User Equipment) both work in a half-duplex mode. This half-duplex mode avoids self-interference and can alleviate the impact of cross-link interference (CLI), but also brings problems such as a decrease in resource utilization and an increase in latency. To solve these problems, it is possible to support flexible duplexing mode or variable link direction (uplink or downlink or flexible) on the TDD spectrum or FDD spectrum. 3GPP (3rd Generation Partner Project) agrees to carry out research on duplex technology, especially on the gNB (NR NodeB) side of the SBFD (Sub Band non-overlapping Full Duplex) mode; the corresponding optimization of system design is an important part of the research.

[0004] PUCCH (Physical Uplink Control Channel) transmission is an important aspect in wireless communication. SUMMARY

[0005] For the scenario of configuring full-duplex symbols and non-full-duplex symbols, how to enhance the PUCCH transmission across multiple slots is an important problem that needs to be considered in the corresponding system design; this application discloses a solution to the above problem. It should be noted that this application can be applied to various wireless communication scenarios, such as scenarios using SBFD mode, scenarios using other types of full-duplex mode in addition to SBFD, scenarios using more flexible duplex mode, etc., and similar technical effects are achieved. In addition, using a unified solution in different scenarios (including but not limited to scenarios using SBFD mode, scenarios using other types of full-duplex mode in addition to SBFD, scenarios using more flexible duplex mode) helps to reduce hardware complexity and cost, or improve performance. In the case of no conflict, the embodiments in any node of this application and the features in the embodiments can be applied to any other node. The embodiments of this application and the features in the embodiments can be arbitrarily combined with each other without conflict.

[0203] Embodiment 4

[0204] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0205] The first 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 (comprising either a transmitter 418 or a receiver 418) and an antenna 420.

[0206] The second 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 an antenna 452.

[0207] In the transmission from the first communication device 410 to the second communication device 450, at the first 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 first communication device 410 to the second 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 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 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 450, and mapping of coded and interleaved data onto various 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 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 reference signals (e.g., pilots) with the data, and then performs an inverse fast Fourier transform (IFFT) to generate a time domain

[0208] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 (transmitters are also numbered 454 as needed to determine whether a receiver 454 or a transmitter 454 is used) receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and converts the RF stream into a baseband multicarrier symbol stream, which is provided to a receive processor 456. The receive processor 456 and a multiple antenna receive processor 458 implement various signal processing functions of the Ll layer. The multiple antenna receive processor 458 performs receive analog precoding / beamforming on the baseband multicarrier symbol stream from the receivers 454. The receive processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream from the receive analog precoding / beamforming operation from the time domain to the frequency domain. In the frequency domain, the physical layer data signals and reference signals are demultiplexed by the receive processor 456, where the reference signals will be used for channel estimation and the data signals are recovered after multiple antenna detection in the multiple antenna receive processor 458 for any spatial streams that are destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and generate soft decisions. The receive processor 456 then 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 channels. 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 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, 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.

[0209] In the transmission from the second communication device 450 to the first communication device 410, at the second 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 described at the first communication device 410 in the transmission from the first communication device 410 to the second 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 for the user plane and control plane. The controller / processor 459 is also responsible for retransmission of lost packets, and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping, channel coding processing, 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 generated spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 via the 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.

[0210] 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 receive functions described at the second communication device 450 in the transmission from the first communication device 410 to the second 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 the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 together implement the functionality of the L1 layer. The 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 second communication device 450 to the first 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 the core network.
