Description

[Technical Field]

[0001] The present application relates to a transmission method and a transmission device in a wireless communication system, and in particular to a transmission method and a transmission device for acquiring system information. [Background technology]

[0002] Network energy saving (NES) is crucial for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operational costs. As 5G (5th Generation Partnership Project) becomes widespread across various industries and geographic regions, it will require much higher data rates to handle more advanced services and applications (e.g., XR). As a result, networks will become increasingly denser, using more antennas, wider bandwidth, and more frequency bands. To keep 5G's environmental impact within manageable limits, new solutions must be researched to improve network energy saving. Therefore, the 3GPP (3rd Generation Partnership Project) RAN#94 meeting approved a Study Item (SI) titled "Research on Network Energy Saving," which supports technology enhancements in the time domain, frequency domain, spatial domain, and power domain. Summary of the Invention

[0003] In the prior art, for a UE (User Equipment) that cannot support a non-terrestrial network (NTN) or whose first node access is not for an NTN, if the UE is a non-RedCap (Reduced Capability) UE, the UE monitors the SSB (Synchronization Signal Block) to obtain a cell's MIB (Master Information Block) message. Only when the cellBarred domain in the MIB message indicates that the cell is not barred and the MIB message indicates the presence of a SIB1 (System Information Block 1) message, the UE obtains the cell's SIB1 according to the pdcch-ConfigSIB1 indicated by the MIB. Reducing the transmission of the PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), PBCH (Physical Broadcast Channel), or SIB1 of a network energy-saving cell is an implementation method for reducing network power consumption. This implementation method affects UEs that do not support network energy-saving or UEs that do not want to access network energy-saving cells. Therefore, it is necessary to strengthen the mitigation of the impact on these UEs.

[0004] In response to the above problem, the present application provides a solution for acquiring system information. In describing the above problem, the NR (New Radio) system is used as an example. This application is also applicable to scenarios such as the LTE (Long Term Evolution) system and the LTE-A (Advanced LTE) system. Furthermore, while this application provides a specific implementation method for network energy conservation, this application can also be used in specific network scenarios to achieve similar technical effects to network energy conservation. Furthermore, although the original intention of this application is for the Uu air interface, this application can also be used for the PC5 interface. Furthermore, although the original intention of this application is for a scenario between a terminal and a base station, this application can also be applied to a V2X (Vehicle-to-Everything) scenario, a communication scenario between a terminal and a relay device, and a communication scenario between a relay device and a base station to achieve similar technical effects to those in the scenario between a terminal and a base station. Furthermore, although the original intention of this application is for a scenario between a terminal and a base station, this application can also be applied to an IAB (Integrated Access and Backhaul) communication scenario to achieve similar technical effects to those in the scenario between a terminal and a base station. Furthermore, although the original intention of this application is for a terrestrial network scenario, this application can also be applied to a non-terrestrial network communication scenario to achieve the same technical effect as the TN scenario. Adopting a unified solution for scenarios also helps reduce hardware complexity and costs.

[0292] Embodiment 4 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 450 and a second communication device 410 communicating with each other in an access network.

[0293] 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 an antenna 452 .

[0294] 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 an antenna 420 .

[0295] For transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to the controller / processor 475 in the second communication device 410. The controller / processor 475 performs L2 layer functions. For transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources to 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 multi-antenna transmit processor 471 perform various signal processing functions for the L1 layer (i.e., physical layer). The transmit processor 416 performs coding and The second communication device 410 performs coding and interleaving to facilitate forward error correction (FEC) 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), and M-quadrature amplitude modulation (M-QAM)) in the second communication device 410. The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes each spatial stream with a reference signal (e.g., a pilot frequency) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter unit 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 to a radio frequency stream and then provides the radio frequency stream to a different antenna 420 .

[0296] For transmissions from the second communication device 410 to the first communication device 450, each receiver 454 in the first communication device 450 receives a signal via a corresponding antenna 452. Each receiver 454 recovers the information modulated onto a radio frequency carrier, converts the radio frequency stream to a baseband multi-carrier symbol stream, and provides the baseband multi-carrier symbol stream to a 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 receiver 454. After the receive analog precoding / beamforming operations, the receive processor 456 converts the baseband multi-carrier symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receive processor 456, the reference signal is used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receive processor 458 to recover all spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receive processor 456 to 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 second communication device 410 on the physical channel. The upper layer data and control signals are then 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 codes and data. The memory 460 may be referred to as a computer-readable medium. For transmission from the second 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, and 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 may be provided to L3 for L3 processing.

[0297] For transmission from the first communication device 450 to the second communication device 410, upper layer data packets are provided to the controller / processor 459 in the first communication device 450 using a data source 467. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function in the second communication device 410 described for transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 also provides the upper layer data packets to the controller / processor 459 ... The controller / processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the assignment, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second 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 and non-codebook-based precoding, and beamforming processing. The transmit processor 468 then modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, which are provided to different antennas 452 by the transmitter 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 symbol stream and then provides the radio frequency symbol stream to the antenna 452.

[0298] For 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 for transmission from the second communication device 410 to the first communication device 450.
