Description

Technical Field

[0001] This application relates to transmission methods and devices in a wireless communication system, and particularly to methods and devices for SDT (Small Data Transmission). Background Art

[0002] In order to reduce the impact on the environment and improve network energy saving (NES), the 3GPP (the 3rd Generation Partnership Project) RAN #94 meeting adopted a research project (Study Item, SI) on "Network Energy Saving Research". Among them, Cell Discontinuous Transmission (CellDTX) and / or Cell Discontinuous Reception (CellDRX) are important research directions.

[0003] Meanwhile, at Rel-17, 3GPP supported uplink small packet data transmission in the inactive state to reduce power consumption, signaling overhead, improve network efficiency, and reduce latency, which is achieved by using two transmission methods: CG (Configured Grant)-SDT and RA (Random Access)-SDT. Summary of the Invention

[0004] In the traditional solution, when certain conditions are met, in the RRC_INACTIVE state, the UE transmits uplink data through CG-SDT; however, the existing protocol does not consider the impact of CG-SDT on the network; in particular but not limited to, when the cell is in the network energy saving state, according to the existing protocol, to ensure the UE performance, the network needs to continue to receive the uplink data on these uplink configured grant resources, which is not conducive to network energy saving. Therefore, CG-SDT needs to be further optimized.

[0005] In view of the above problems, the present application provides a solution for performing SDT in the case of network energy saving. In the above problem description, the NR system is taken as an example, and the present application is also applicable to scenarios such as LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), or future 6G systems, achieving technical effects similar to those of the NR system; further, although the present application gives specific implementation manners for CG-SDT, the present application can also be used in other SDT scenarios, achieving technical effects similar to those of CG-SDT. Further, adopting a unified design solution for different scenarios also helps to reduce hardware complexity and cost. Further, although the present application gives specific implementation manners for the SDT scenario, the present application can also be used in the scenario of RNA (RAN (Radio Access Network)-based Notification Area) update, achieving technical effects similar to those of the SDT scenario. Further, although the present application gives specific implementation manners for the SDT scenario, the present application can also be used in the EDT (Early Data Transmission) scenario, achieving technical effects similar to those of the SDT scenario. Further, although the present application gives specific implementation manners for the network energy saving scenario, the present application can also be used in the UE energy saving scenario, achieving technical effects similar to those of the network energy saving scenario. Further, although the present application gives specific implementation manners for cell DTX and / or cell DRX, the present application can also be used in scenarios such as UE DRX and / or UE eDRX, achieving technical effects similar to those of cell DTX and / or cell DRX. Further, although the original intention of the present application is for the Uu air interface, the present application can also be used in the PC5 interface, achieving technical effects similar to those of the Uu air interface. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between the terminal and the relay, and between the relay and the base station, achieving technical effects similar to those in the terminal-to-base station scenario. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the IAB (Integrated Access and Backhaul) communication scenario, achieving technical effects similar to those in the terminal-to-base station scenario.Further, although the original intention of this application is for the Terrestrial Network (TN) scenario, this application is also applicable to the communication scenario of the Non-Terrestrial Network (NTN), achieving technical effects similar to those in the TN scenario. Further, although the original intention of this application is for the traditional communication waveform transmission scenario, this application is also applicable to the transmission scenario combining communication and sensing waveforms, achieving technical effects similar to those in the traditional communication waveform transmission scenario. In addition, adopting a unified solution for different scenarios helps to reduce hardware complexity and cost.

[0337] Example 3

[0338] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture for controlling plane 300 is presented in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. Layer 1 will be referred to as PHY301 herein. Layer 2 (L2 layer) 305 is above PHY301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell.

[0345] Example 4

[0346] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 as follows. Figure 4 It is a block diagram of a first communication device 450 and a second communication device 410 that communicate with each other in an access network.

[0347] The first communication device 450 includes 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.

[0348] The second communication device 410 includes 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.

[0349] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the 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, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation 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 multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, 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), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream and then provides it to different antennas 420.

[0350] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives signals through its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to the 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 receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 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. Subsequently, the upper layer data and control signals are 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 code and data. The memory 460 may be referred to as a computer-readable medium. In the 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, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0351] 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 described at the second communication device 410 in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and 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. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. 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 it to the antenna 452.

[0352] 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 described at the first communication device 450 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 corresponding 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 jointly implement L1 layer functions. A controller / processor 475 implements L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium.
