Description

Technical Field

[0001] The present application relates to a signal transmission method and device in a wireless communication system, and in particular to a PHR (Power Headroom Report) triggering method and device. Background Art

[0002] Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project) LTE (Long-Term Evolution) system and NR (New Radio) system. It is achieved by configuring multiple antennas at communication nodes, such as base stations or UE (User Equipment) to obtain additional spatial degrees of freedom. Multiple antennas improve communication quality by beamforming to form beams pointing in a specific direction. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points) / panels, additional diversity gain can be obtained by utilizing the spatial differences between different TRPs / panels. Among them, deploying heterogeneous networks so that UEs can receive downlink (DL) transmissions from a gNB but send uplink (UL) transmissions to the gNB or non-co-located TRP / panel is an important enhancement to improve uplink throughput. Furthermore, the TRP / panel receiving the UL can reduce or even shut down DL transmissions to reduce energy consumption.

[0003] In December 2023, the WI (Work Item) of NRMIMO Phase 5 was passed at the RAN (Radio Access Network) #102 plenary meeting. The RAN1 working group will at least enhance UL power control (PC) in the Rel-19 stage to support this UL / DL asymmetric deployment scenario; this includes configuring path loss offset for the UE to accurately calculate the path loss associated with the UE and the TRP / panel; and supporting two closed-loop PC adjustment states of SRS (Sounding Resource Signal) for gNB DLCSI (Channel State Information) acquisition and UL multi-TRP transmission. Summary of the invention

[0004] In NR, when the timer (Timer) used by the UE for PHR timing expires and the measured path loss (Pathloss) changes by more than the configured threshold, the UE will report the PHR to the base station. In the current system, PHR is configured based on the cell group. In the UL / DLasymmetric scenario, the base station needs to maintain the power control process between the UE and the gNB, as well as between the UE and the gNB's remote UL TRP. Therefore, how to report the UE's PHR more accurately and timely based on the existing PHR reporting mechanism is a problem that needs to be solved.

[0005] In view of the above problems, the present application discloses a solution. It should be noted that, in the description of the above problems, the NR (New Radio) system is used as an example, and the present application is also applicable to scenarios such as the future 6G system, and achieves technical effects similar to the NR system; further, although the original intention of the present application is for UL / DL asymmetric, cellular network, uplink transmission, multi-beam / TRP / panel scenarios, the present application can also be applied to other non-UL / DL asymmetric scenarios; further, for different scenarios (such as other non-UL / DL asymmetric scenarios, including but not limited to sidelink transmission, downlink transmission, single beam / TRP / panel, RIS (Reconfigurable Intelligent Surface), Vehicle to Everything (V2X), NCR (Network Control Repeater) capacity enhancement system, short-range communication system, NTN (Non Terrestrial Network), IoT (Internet of Things), URLLC (Ultra Reliable Low Latency The use of a unified design solution for wireless communication, ultra-robust low-latency communication, and networks, etc., can also help reduce hardware complexity and cost.

L1 is the lowest layer and implements various PHY (PHYsical layer) signal processing functions. L1 will be referred to as PHY 301 in this article. L2 305 is above PHY 301 and is responsible for the link between the first node device and the second node device, or between two UEs through 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.

[0189] Example 4

[0190] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in the attached Figure 4 Attached Figure 4is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0191] The first communication device 410 includes 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 .

[0192] The second communication device 450 includes 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.

[0193] In 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 the functionality of L2. In 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 operations, 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., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, as well as mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-PSK, M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding and beamforming processing, to generate 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., pilot) in the time domain and / or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying a time domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation 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.

[0194] 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 RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of L1. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, where the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any parallel stream with the second communication device 450 as the destination. The symbols on each parallel stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving 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 channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of L2. The controller / processor 459 may be associated with a memory 460 storing program codes and data. The memory 460 may be referred to as a computer-readable medium. In DL, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the upper layer data packets from the core network. The upper layer data 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 ACKnowledgement (ACK) and / or negative ACKnowledgement (Negative ACKnowledgement, NACK) protocols to support HARQ operations.

[0195] 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 function at the first communication device 410 described in 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, and implements L2 functions for the user plane and the control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first 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 precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via 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 it to the antenna 452.

[0196] 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 reception 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 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 the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of L1. The controller / processor 475 implements the L2 functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transmission and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 can be provided to the core network. The controller / processor 475 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
