Description

TECHNICAL FIELD

[0001] The present application relates to transmission method and apparatus in wireless communication system, in particular to transmission scheme and apparatus of uplink power control reporting in wireless communication. BACKGROUND

[0002] 5G wireless cellular communication network system (5G-RAN) enhances the uplink power control of UE on the basis of the original LTE (Long-Term Evolution). Compared with LTE, because the NR system does not have CRS (Common Reference Signal), the path loss (Pathloss) measurement required for uplink power control needs to be performed using CSI-RS (Channel State Information Reference Signal) and SSB (SS / PBCH Block). In addition, the biggest feature of the NR system is to introduce a beam management mechanism, and the terminal can use multiple different transmission and reception beams for communication, and thus the terminal needs to be able to measure multiple path losses corresponding to multiple beams, wherein one way to determine the path loss is to indicate a certain associated downlink RS resource through SRI (Sounding Reference Signal Resource Indicator) in DCI.

[0003] In the discussion of NRR17, the scenario of configuring multiple panels on the terminal side has been adopted, and the impact of introducing multiple panels on power control also needs to be considered accordingly. SUMMARY

[0004] In the discussion of NRR17, the transmission of the terminal is enhanced, and one important aspect is the introduction of two panels. The terminal can use two panels to transmit on two transmission beams at the same time to obtain better spatial diversity gain. However, one important indicator of uplink transmission is power control. Whether two panels use the same power control parameters as one panel when used at the same time, and whether power is dynamically allocated between two panels, all of these will affect the practice of uplink power control under multiple panels. Further, the reporting mechanism of the existing PHR (Power Headroom Report) also needs to be reconsidered.

[0005] For the uplink power control problem in the above multi-panel scenario, this application discloses a solution. It should be noted that in the description of this application, multi-panel is only taken as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems, such as single-panel scenarios, or for different technical fields, such as technical fields other than uplink power control, such as measurement reporting fields, uplink data transmission, and other non-uplink power control fields to achieve similar technical effects. In addition, the use of a unified solution in different scenarios (including but not limited to multi-panel scenarios) helps to reduce hardware complexity and cost. In the case of no conflict, the embodiments in the first node device and the features in the embodiments can be applied to the second node device, and vice versa.

Figure 3 Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300, Figure 3 ​The radio protocol architecture for the control plane 300 between a first communication node device (UE, gNB or RSU in V2X) and a second communication node device (gNB, UE or RSU in V2X) is shown with 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. The L1 layer will be referred to as the PHY 301 herein. Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the first communication node device and the second communication node device using the PHY 301.

[0227] Example 4

[0228] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in FIG. 4. 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.

[0229] The first 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 antennas 452.

[0230] The second 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 antennas 420.

[0231] ​In the transmission from the second communication device 410 to the first communication device 450, at the second 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 second communication device 410 to the first 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 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 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 410, and mapping of coded bits to modulation symbols 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 with reference signals (e.g., pilot) in the time and / or frequency domain, and then performs an inverse fast Fourier transform (IFFT) to generate a time-domain multicarrier symbol stream for the physical channel. The multiple antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 into a radio frequency stream, and then provides the radio frequency stream to the corresponding antenna 420.

[0232] In transmissions from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the recovered information at baseband, as a stream of symbols, to a receive processor 456. The receive processor 456 and a multiple access receiver processor 458 implement various signal processing functions of the Ll layer. The multiple access receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multiple access symbol stream from the receivers 454. The receive processor 456 converts the baseband multiple access symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed from the received symbol stream by the receive processor 456, with the reference signals to be used for channel estimation and the data signals to be recovered after multiple access detection in the multiple access receiver processor 458 for any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and used to generate soft decisions. The receive processor 456 then decodes and de-interleaves 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 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 transmissions 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, 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.

[0233] 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 at the second communication device 410 described in the transmission from the second communication device 410 to the first 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, implements L2 layer functionality for the user plane and control plane. The controller / processor 459 is also responsible for error detection, retransmission of lost packets, and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping, 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, and then the transmit processor 468 modulates the resulting spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 via 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.

[0234] 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 at the first communication device 450 described 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 respective 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 collectively implement the functionality of the L1 layer. A 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 first communication device 450 to the second 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 a core network.

An antenna group is connected to the baseband processor through an RF (Radio Frequency) chain, with different antenna groups corresponding to different RF chains. The mapping coefficients of all antennas within the positive integer number of antenna groups included in a given antenna port to the given antenna port form the beamforming vector corresponding to the given antenna port. The mapping coefficients of multiple antennas within any given antenna group within the positive integer number of antenna groups included in the given antenna port to the given antenna port form the analog beamforming vector of the given antenna group. The analog beamforming vectors corresponding to the positive integer number of antenna groups are diagonally arranged to form the analog beamforming matrix corresponding to the given antenna port.

The mapping coefficients from multiple antennas in antenna group #1 and multiple antennas in antenna group #2 to antenna port group #1 form analog beamforming vector #1 and analog beamforming vector #2, respectively, and the mapping coefficients from antenna group #1 and antenna group #2 to antenna port group #1 form a digital beamforming vector #1. The beamforming vector corresponding to any antenna port in antenna port group #0 is obtained by multiplying the analog beamforming vector #0 and the digital beamforming vector #0. The beamforming vector corresponding to any antenna port in the antenna port group #1 is obtained by multiplying the analog beamforming matrix formed by the diagonal arrangement of the analog beamforming vector #1 and the analog beamforming vector #2 with the digital beamforming vector #1.
