[0005] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0006] In 5G NR (New Radio) systems, both base stations and terminal devices will be equipped with multiple antenna panels. The NR Rel-16 standard already supports base stations transmitting radio signals simultaneously through multiple antenna panels; however, even with multiple antenna panels, terminal devices only support transmission based on antenna panel selection, meaning that only one antenna panel can transmit wirelessly at a time. In the future evolution of 5G NR systems, supporting simultaneous transmission of radio signals from multiple antenna panels on both base stations and terminal devices is an important technological direction for improving system capacity. Summary of the Invention

[0067] In Embodiment 1, the first node in this application receives a first signaling in step 101; and transmits a target signal and a target reference signal group in the target time-frequency resource block in step 102. The first signaling is used to indicate the target time-frequency resource block; the target time-frequency resource block includes multiple resource particles; the target signal includes a first sub-signal and a second sub-signal, the number of layers of the target signal being equal to the sum of the number of layers of the first sub-signal and the second sub-signal; the first signaling is used to indicate a first reference signal resource group and a second reference signal resource group, the first reference signal resource group being used to determine the antenna port for transmitting the first sub-signal, and the second reference signal resource group being used to determine the antenna port for transmitting the second sub-signal; the target reference signal group includes P reference signals, each of which is transmitted by one of P antenna ports, where P is a positive integer greater than 1; the first antenna port... The first reference signal is any one of the P antenna ports, and the first reference signal is a reference signal transmitted by the first antenna port from among the P reference signals. The first resource particle is any resource particle occupied by the first reference signal, and the transmission power of the first reference signal on the first resource particle is linearly related to the linear value of the first factor. The first factor is related to whether the first antenna port is associated with the first reference signal resource group or the second reference signal resource group. When the first antenna port is associated with the first reference signal resource group, the first factor is related to the layer number of the first sub-signal. When the first antenna port is associated with the second reference signal resource group, the first factor is related to the layer number of the second sub-signal. The first reference signal resource group includes at least one reference signal resource, and the second reference signal resource group includes at least one reference signal resource.

[0068] As an example, the first signaling is physical layer signaling.

[0069] As an example, the first signaling is DCI (Downlink Control Information) signaling.

[0070] As an example, the first signaling is DCI signaling used to schedule PUSCH (Physical Uplink SharedCHannel).

[0071] As an example, the first signaling is transmitted on the PDCCH (Physical Downlink Control Channel).

[0072] Typically, a resource element (RE) occupies one subcarrier in the frequency domain and one symbol in the time domain.

[0073] As an example, the symbol is a single-carrier symbol.

[0074] As an example, the symbol is a multi-carrier symbol.

[0075] As an example, the multicarrier symbol is an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0076] As an example, the multi-carrier symbol is an SC-FDMA (Single Carrier-Frequency Division Multiple Access) symbol.

[0077] As an example, the multicarrier symbol is a DFT-S-OFDM (Discrete Fourier Transform Spread OFDM) symbol.

[0078] As an example, the multi-carrier symbol is an FBMC (Filter Bank Multi Carrier) symbol.

[0090] As an example, the target signal carries a transport block (TB).

[0091] As an example, the target signal carries two transmission blocks, with the first sub-signal and the second sub-signal carrying the two transmission blocks respectively.

[0092] As an example, the first sub-signal and the second sub-signal each occupy a different layer(s) of a PUSCH.

[0093] As an example, on the PUSCH that transmits the target signal, any layer occupied by the first sub-signal is different from any layer occupied by the second sub-signal.

[0094] As an example, the first sub-signal and the second sub-signal are spatially multiplexed.

[0096] As an example, the first sub-signal and the second sub-signal occupy the same resource particles.

[0097] As one embodiment, the first sub-signal and the second sub-signal are partially or completely overlapping.

[0098] As an example, the number of layers of the target signal is equal to the rank of the target signal.

[0099] As an example, the rank of the target signal is r, and the target signal includes r layers; the first sub-signal includes the r1 layer in the r layers, and the second sub-signal includes the r-r1 layers in the r layers other than the r1 layer; r is a positive integer greater than 1, and r1 is a positive integer less than r.

[0100] Typically, the definition of a layer can be found in Sections 5 and 6 of 3GPP TS38.214.

[0101] As an example, when the transmission scheme of the target signal is based on codebook-based uplink transmission, both the transmission scheme of the first sub-signal and the transmission scheme of the second sub-signal are based on codebook-based uplink transmission.

[0105] As an example, the transmission scheme of the first sub-signal is based on non-codebook-based uplink transmission.

[0106] As one embodiment, the transmission scheme of the first sub-signal is either codebook-based uplink transmission or non-codebook-based uplink transmission.

[0107] As an example, the transmission scheme for the second sub-signal is based on codebook-based uplink transmission.

[0108] As an example, the transmission scheme for the second sub-signal is based on non-codebook-based uplink transmission.

[0109] As one embodiment, the transmission scheme of the second sub-signal is either codebook-based uplink transmission or non-codebook-based uplink transmission.

[0110] As an example, the transmission scheme of the first sub-signal is the same as that of the second sub-signal.

[0111] As an example, the transmission scheme of the first sub-signal and the transmission scheme of the second sub-signal are configured by higher-level parameters respectively.

[0112] As an example, the codebook-based uplink transmission is described in section 6.1.1.1 of 3GPP TS 38.214.

[0113] As an example, the non-codebook based uplink transmission is described in section 6.1.1.2 of 3GPP TS 38.214.

Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, 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. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 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 second communication node device.

RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices.

The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio 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 L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

In the L2 layer, 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 the L1 layer (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 constellation mapping based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more parallel streams. 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 subsequently uses inverse fast Fourier transform (IFFT) 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.

[0239] 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 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 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 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 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 Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0240] 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 the L2 layer. Similar to the transmission function 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 layer 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.

[0241] 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 layer functions. The controller / processor 475 implements the 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 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.

[0284] Example 6

[0285] Example 6 illustrates a schematic diagram of the relationship between the transmission power of a first reference signal on a first resource particle and a first factor according to an embodiment of this application; as shown in the attached diagram. Figure 6 As shown.

[0286] In Example 6, the ratio of the transmit power of the first reference signal on the first resource particle to the reference power is equal to the linear value of the first factor; the reference power is related to whether the first antenna port is associated with the first reference signal resource group or the second reference signal resource group; when the first antenna port is associated with the first reference signal resource group, the reference power is the transmit power of the first sub-signal on each layer per RE; when the first antenna port is associated with the second reference signal resource group, the reference power is the transmit power of the second sub-signal on each layer per RE.

[0287] Typically, the unit of the transmission power of the first reference signal on the first resource particle and the unit of the reference power are both mW (milliwatt).

[0288] Typically, the "ratio of the transmitted power to the reference power on the first resource particle" is the value obtained by dividing the transmitted power on the first resource particle by the reference power.

[0289] As an example, "the transmission power of the first sub-signal per layer per RE" is equal to the total transmission power of the first sub-signal divided by the number of layers of the first sub-signal and then divided by the number of REs occupied; "the transmission power of the second sub-signal per layer per RE" is equal to the total transmission power of the second sub-signal divided by the number of layers of the second sub-signal and then divided by the number of REs occupied.

[0291] Example 7

[0292] Example 7 illustrates a schematic diagram of a first factor according to an embodiment of this application; as attached. Figure 7 As shown.

[0293] In Example 7, P1 is the number of antenna ports among the P antenna ports that are associated with the first reference signal resource group, and P2 is the number of antenna ports among the P antenna ports that are associated with the second reference signal resource group. The sum of P1 and P2 is equal to P. When the first antenna port is associated with the first reference signal resource group, the first factor is also related to P and P1. When the first antenna port is associated with the second reference signal resource group, the first factor is also related to P and P2.

[0294] As an example, the P reference signals occupy the same time-domain resources.

[0295] As an example, the sentence "the first factor is also related to P and P1" means that the first factor has at least a functional relationship with P and P1; the sentence "the first factor is also related to P and P2" means that the first factor has at least a functional relationship with P and P2.

[0296] As an example, the sentence "the first factor is also related to P and P1" means that the first factor is at least mapped to P and P1; the sentence "the first factor is also related to P and P2" means that the first factor is at least mapped to P and P2.

[0297] As an example, the sentence "the first factor is also related to P and P1" means that the first node obtains the first factor by looking up a table based on at least P and P1; the sentence "the first factor is also related to P and P2" means that the first node obtains the first factor by looking up a table based on at least P and P2.

[0298] As an example, the sentence "the first factor is also related to P and P1" means that the first factor is also related to the ratio of P and P1; the sentence "the first factor is also related to P and P2" means that the first factor is also related to the ratio of P and P2.

[0299] As an example, the sentence "the first factor is also related to P and P1" means that the first factor is linearly related to the ratio of P and P1; the sentence "the first factor is also related to P and P2" means that the first factor is linearly related to the ratio of P and P2.

[0300] As an example, the sentence "the first factor is also related to P and P1" means that the first factor is equal to the sum of the second factor and the third factor, and the third factor is related to the ratio of P and P1; the sentence "the first factor is also related to P and P2" means that the first factor is equal to the sum of the second factor and the third factor, and the third factor is related to the ratio of P and P2.
