Description

Technical Field

[0001] This application relates to signal transmission methods and apparatus in wireless communication systems, and more particularly to power control methods and apparatus in wireless communication. Background Technology

[0002] With the development of mobile communication, especially the application of 5G active antenna arrays, the architecture of communication and sensing systems is becoming increasingly consistent, and the trend of integrating communication and sensing capabilities in the network is becoming more and more apparent. Integrated Sensing and Communication (ISAC) technology refers to the unified design of communication and sensing functions through joint design of air interfaces and protocols, multiplexing of time-frequency-space resources, and sharing of hardware devices. This enables the wireless network to achieve high-precision and refined sensing functions while conducting high-quality communication interactions, thereby improving the system's spectral efficiency, energy efficiency, and hardware efficiency, and obtaining integration gain. Furthermore, the mutual assistance and cooperation between communication and sensing functions can also improve each other's performance, thus obtaining coordination gain.

[0003] During the 5G Rel-18 (Release-18) phase, 3GPP (the 3rd Generation Partnership Project) SA1 (Services & Systems Aspects 1) conducted extensive and comprehensive research on ISAC scenario use cases. In June 2023, the 3GPP SA#100 plenary meeting adopted the Technical Report (TR) 22.837 (Rel-19) on Feasibility Study on Integrated Sensing and Communication, outlining 32 use cases across three major scenarios supported by ISAC: object detection and tracking, environment monitoring, and motion monitoring. In December 2023, the 3GPP RAN (Radio Access Network) #102 plenary meeting adopted the Study on channel modelling for Integrated Sensing and Communication. The Study Item (SI) of Communication (ISAC) for NR, the RAN1 working group will also focus on supporting object detection and tracking scenarios in the Rel-19 phase, taking the channel model in 38.901 as a starting point, and lead the research on ISAC channel modeling, etc. ISAC is also regarded as one of the key potential technology development directions and six major application scenarios in the 6G phase. Summary of the Invention

[0004] In wireless communication systems, power control is a crucial way to optimize system performance. Reasonable power control can reduce interference, improve spectral efficiency, effectively reduce energy consumption, extend equipment battery life and service life, and adapt to different transmission conditions and mobility requirements. However, after introducing sensing signals into wireless communication systems, there are also problems such as interference between sensing and communication systems, spectral interference between sensing and communication systems, and optimization of sensing performance. Especially when the total transmission power is limited, how to balance the performance of sensing and communication and perform power control on sensing signals and cellular signals is a problem worth studying.

[0336] As an example, when the sum of the first reference power value and the second reference power value is greater than the first maximum power value, the first power value is equal to the first reference power value, and the second power value is less than the second reference power value.

[0337] As an example, when the sum of the first reference power value and the second reference power value is not greater than the first maximum power value, the first power value is equal to the first reference power value, and the second power value is equal to the second reference power value; when the sum of the first reference power value and the second reference power value is greater than the first maximum power value, the product of the sum of the first reference power value and the second reference power value and a certain factor is not greater than the first maximum power value, the first power value is equal to the product of the first reference power value and the certain factor, and the second power value is equal to the product of the second reference power value and the certain factor.

[0338] As an example, when the sum of the first reference power value and the second reference power value is not greater than the first maximum power value, the first power value is equal to the first reference power value, and the second power value is equal to the second reference power value; when the sum of the first reference power value and the second reference power value is greater than the first maximum power value, the first power value is equal to the first reference power value, and the second power value is equal to the difference between the first maximum power value and the first power value.

[0339] As an example, when the sum of the first reference power value and the second reference power value is not greater than the first maximum power value, the first power value is equal to the first reference power value, and the second power value is equal to the second reference power value; when the sum of the first reference power value and the second reference power value is greater than the first maximum power value, the second power value is equal to the smaller of the second reference power value and a certain power value, and the first power value is equal to the smaller of the difference between the first reference power value and the first maximum power value minus the second power value.

[0388] Example 3

[0389] Example 3 illustrates a schematic diagram of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown.

[0390] Figure 3 This is a schematic diagram illustrating an embodiment of a wireless protocol architecture for the user plane 350 and the control plane 300. Figure 3The wireless protocol architecture for the control plane 300 between the first communication node device (UE or RSU in V2X, onboard equipment or onboard communication module) and the second node device (gNB, UE or RSU in V2X, onboard equipment or onboard communication module), or between two UEs, is illustrated using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical layer) signal processing functions. L1 will be referred to as PHY 301 in this document. L2305 sits above PHY 301 and is responsible for the link between the first and second node devices, or between two UEs, via PHY 301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering 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. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and using RRC signaling between the second communication node device and the first communication node device to configure the lower layer.The wireless protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The wireless protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2355, RLC sublayer 353 in L2355, and MAC sublayer 352 in L2355.

SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and Data Radio Bearers (D resource blocks) to support service diversity.

[0402] Example 4

[0403] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in the access network.

[0404] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0405] The second 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.

[0406] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 functionality. In the DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for L1 (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-PSK, and M-Quadrature Amplitude Modulation (M-QAM)). 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, generating one or more parallel streams. The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0407] In the 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 through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various L1 signal processing functions. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier 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 receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating 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 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements L2 functionality. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above L2. Various control signals may also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0408] 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 the controller / processor 459. The data source 467 represents all protocol layers above L2. Similar to the transmission functions at the first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0409] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 function. The controller / processor 475 implements the L2 function. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.
