Description

Technical Field

[0001] This application relates to methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for transmitting PUSCH (Physical Uplink Shared Channel) wireless signals in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the systems. In traditional wireless communication systems, terminals supporting carrier aggregation technology can transmit and receive data through multiple carriers in multiple cells to obtain greater service bandwidth and higher transmission rates, but the utilization efficiency of fragmented spectrum resources is not high. Supporting the configuration of multiple frequency domain resources that are not contiguous in the frequency domain within a serving cell and allowing physical channel transmission across multiple frequency domain resources in the serving cell can not only achieve large service bandwidth and high transmission rates, but also effectively improve the utilization efficiency of fragmented spectrum resources and reduce base station energy consumption. Considering the above scenarios, it is necessary to study techniques for optimizing physical channel transmission by configuring multiple frequency domain resources that are not contiguous in the frequency domain.

[0003] In 5G NR (New Radio), the terminal PUSCH transmission waveform can be either CP-OFDM (Cyclic Prefix Orthogonal Frequency Division Multiplexing) or DFT-s-OFDM (Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing), and the PUSCH transmission waveform can be dynamically switched through network configuration or signaling to adapt to different transmission scenarios. Summary of the Invention

[0004] The inventors discovered through research that when PUSCH transmission is allowed across multiple frequency domain resources in a serving cell with discontinuous frequency domain configurations, determining the PUSCH transmission waveform requires further investigation if the applicable uplink transmission waveforms differ across the multiple frequency domain resources. To address this issue, this application discloses a solution where, in a cell supporting transmission across multiple discontinuous frequency domain resources, the UE determines the PUSCH transmission waveform based on the frequency domain resources occupied by the PUSCH. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined. It should be noted that although many embodiments of this application are focused on PUSCH, this application is also applicable to other uplink transmission scenarios. Furthermore, although this application is initially intended for terminal and base station scenarios, it is also applicable to relay and base station, and terminal and terminal scenarios, achieving similar technical effects in terminal and base station scenarios. In addition, adopting a unified solution for different scenarios helps reduce hardware complexity and cost. In particular, the interpretation of terms, nouns, functions and variables in this application (unless otherwise specified) can be found in the definitions in the 3GPP specification protocols TS38 and TS37 series.

[0005] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0006] Send the first PUSCH;

[0007] The transmission waveform of the first PUSCH depends on the frequency domain resources occupied by the first PUSCH, and the frequency domain resources occupied by the first PUSCH overlap with the first frequency domain resource set at least.

[0008] The transmission waveform of the first PUSCH depends on the frequency domain resources occupied by the first PUSCH, including: when the frequency domain resources occupied by the first PUSCH are a subset of the first frequency domain resource set, the transmission waveform of the first PUSCH is a first waveform; when the frequency domain resources occupied by the first PUSCH overlap with the second frequency domain resource set, the transmission waveform of the first PUSCH is a second waveform; the first frequency domain resource set and the second frequency domain resource set are orthogonal.

[0009] As one embodiment, PUSCH transmission on the first frequency domain resource set is configured to apply the first waveform, and PUSCH transmission on the second frequency domain resource set is configured to apply the second waveform.

[0010] As an example, when the frequency domain resources occupied by the first PUSCH overlap only with the first frequency domain resource set, the transmitted waveform of the first PUSCH is the first waveform; when the frequency domain resources occupied by the first PUSCH overlap with both the first frequency domain resource set and the second frequency domain resource set, the transmitted waveform of the first PUSCH is the second waveform.

[0011] Typically, the first frequency domain resource set and the second frequency domain resource set are each a carrier.

[0012] Typically, the first frequency domain resource set and the second frequency domain resource set are each a subband.

[0013] As an example, the above method uses a unified transmitter processing, which helps to reduce the implementation complexity of the transmitter.

[0014] As an example, the above method can determine the transmission waveform of the first PUSCH by whether the frequency domain resources occupied by the first PUSCH overlap with the first frequency domain resource set and the second frequency domain resource set.

[0015] As an example, in the above method, the first node determines the transmission waveform of the first PUSCH according to a preset rule.

[0016] As an example, the determination of the transmission waveform of the first PUSCH in the above method is implemented by the UE.

[0017] As an example, the above method can simplify signaling.

[0018] According to one aspect of this application, the above method is characterized by comprising:

[0019] Receive the first DCI;

[0020] Wherein, the first DCI indicates the frequency domain resources occupied by the first PUSCH.

[0021] As an example, the first DCI does not explicitly indicate the transmitted waveform of the first PUSCH.

[0022] As an example, the first DCI does not include a transform precoder indicator.

[0023] As an example, when the first DCI does not display the transmission waveform indicating the first PUSCH, the first node determines the transmission waveform of the first PUSCH based on the frequency domain resources occupied by the first PUSCH.

[0024] As an example, the advantage of the above method is that it can reduce the signaling overhead of instructing the transmission waveform of the first PUSCH.

[0025] According to one aspect of this application, the above method is characterized in that the first waveform is CP-OFDM and the second waveform is DFT-s-OFDM (Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing).

[0026] Specifically, PUSCH transmissions on the first frequency domain resource set are configured to disable transform precoding, while PUSCH transmissions on the second frequency domain resource set are configured to enable transform precoding.

[0027] As an example, the above method is beneficial for reducing the PAPR (Peak to Average Power Ratio) of the first PUSCH.

[0028] As an example, the above method helps to improve the uplink coverage of the first PUSCH.

[0029] As an example, the above method is beneficial for achieving higher power amplifier (PA) efficiency.

[0030] As an example, the above method is beneficial for PUSCH transmission in power-constrained scenarios.

[0031] According to one aspect of this application, the above method is characterized in that the first waveform is DFT-s-OFDM and the second waveform is CP-OFDM;

[0032] Specifically, PUSCH transmissions on the first frequency domain resource set are configured to enable transform precoding, while PUSCH transmissions on the second frequency domain resource set are configured to disable transform precoding.

[0033] As an example, the above method is beneficial for improving spectral efficiency.

[0034] As an example, the above method is beneficial for achieving multi-layer transmission and improving data transmission efficiency.

[0035] As an example, the above method does not require transformation precoding processing at the transmitter, which helps to reduce transmission delay.

[0036] According to one aspect of this application, the method is characterized in that the difference between the size of the frequency domain resources occupied by the first PUSCH that overlap with the second frequency domain resource set and the size of the frequency domain resources occupied by the first PUSCH that overlap with the first frequency domain resource set is greater than or not less than a first threshold.

[0037] As an example, the feature of the above method is that when the frequency domain resources occupied by the first PUSCH overlap with the second frequency domain resource set, whether the transmitted waveform of the first PUSCH is the second waveform further depends on the relative quantities of the frequency domain resources occupied by the first PUSCH that overlap with the second frequency domain resource set and the frequency domain resources occupied by the first PUSCH that overlap with the first frequency domain resource set.

[0038] As an example, the characteristic of the above method is that when the frequency domain resources occupied by the first PUSCH that overlap with the second frequency domain resource set are small, the transmission waveform of the first PUSCH is still the first waveform.

[0039] As an example, the feature of the above method is that when the frequency domain resources occupied by the first PUSCH that overlap with the second frequency domain resource set are sufficient, the transmission waveform of the first PUSCH is the second waveform.

[0044] As an example, the transmission direction on the first frequency domain resource set is the same as the transmission direction on the second frequency domain resource set.

[0045] As an example, the first cell is configured with multiple carriers, and the frequency domain resources corresponding to the multiple carriers are orthogonal to each other. The frequency domain resources corresponding to one carrier include multiple consecutive subcarriers.

[0046] As an example, the first frequency domain resource set includes frequency domain resources corresponding to at least one of the plurality of carriers.

[0047] As one embodiment, the second frequency domain resource set includes frequency domain resources corresponding to at least one of the plurality of carriers.

[0048] According to one aspect of this application, the above method is characterized in that the maximum power reduction (MPR) of the first PUSCH depends on the frequency domain resources occupied by the first PUSCH.

[0049] Wherein, when the frequency domain resources occupied by the first PUSCH are a subset of the first frequency domain resource set, the maximum power back-off of the first PUSCH is a first candidate value; when the frequency domain resources occupied by the first PUSCH overlap with the second frequency domain resource set, the maximum power back-off of the first PUSCH is a value between the first candidate value and the second candidate value.

[0218] Example 3

[0219] 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. 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 radio protocol architecture of the UE and gNB control plane 300 is illustrated using 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the UE and gNB through PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side.

[0227] Example 4

[0228] Example 4 illustrates a hardware module schematic diagram of a communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0229] 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.

[0230] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, 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.

[0231] 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 or from the data source 477 are provided to the controller / processor 475. The core network and data source 477 represent all protocol layers above the L2 layer. 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 retransmitting 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). Transmit processor 416 performs encoding and interleaving to facilitate FEC (Forward Error Correction) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), M-PSK (M-Phase Shift Keying), M-QAM (M-Quadrature Amplitude Modulation)). 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 spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses IFFT (Inverse Fast Fourier Transform) to generate a physical channel carrying the time-domain multicarrier symbol stream. 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 transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0232] 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 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 signal processing functions of the L1 layer. 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 FFT (Fast Fourier Transform) 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 spatial stream destined for the first communication device 450. Symbols on each spatial 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 second 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 the functions of Layer 2. 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 transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover higher-layer data packets from the second communication device 410. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0233] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, upper-layer data packets are provided to the controller / processor 459 using a data source 467. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions 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, encryption, packet segmentation and reordering, and multiplexing between the logical and transport channels, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second 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 spatial 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.

[0234] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function 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 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 layer function. The controller / processor 475 implements the L2 layer 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. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper-layer data packets from the first communication device 450. Upper-layer data packets from the controller / processor 475 can be provided to the core network or all protocol layers above the L2 layer, and various control signals can also be provided to the core network or L3 for L3 processing.
