[0171] In one embodiment, the statements in this application that "the transform precoder on any cell in the first cell set is enabled" and "the transform precoder is enabled for PUSCH transmissions on any cell in the first cell set" are equivalent or interchangeable.

[0172] In one embodiment, the statements in this application that "a transform precoder on any cell in the first cell set is enabled" and "a transform precoder is enabled for a PUSCH scheduled by the first type of signaling on any cell in the first cell set" are equivalent or interchangeable.

[0173] In one embodiment, the statements in this application that "a transform precoder on any cell in the first cell set is enabled" and "each parameter in the first parameter set is a parameter in the active uplink BWP configuration of one cell in the first cell set, and any parameter in the first parameter set indicates that a transform precoder is enabled" are equivalent or interchangeable.

[0174] In one embodiment, the statements in this application that "the transform precoder on any cell in the first cell set is enabled" and "the transform precoder is configured to be enabled in the active uplink BWP configuration of any cell in the first cell set" are equivalent or interchangeable.

[0175] In one embodiment, the first node expects all cells in the first cell set to have the same setting regarding whether or not the transform precoder is enabled.

[0176] In one embodiment, the first node does not expect cells in the first cell set to have different settings regarding whether or not the transform precoder is enabled.

[0177] In one embodiment, the given cell is a cell in a first cell set, and the first signaling is used to schedule at least one PUSCH to be transmitted on the given cell. For PUSCH transmission on the given cell, when corresponding transform precoding is not enabled, for UL (uplink) transmission based on a partially coherent codebook and a non-coherent codebook, the actual number of UL phase tracking reference signal (PT-RS) ports is determined based on the number of layers indicated by the TPMI and / or a second domain in the first signaling, where the second domain is a field of precoding information and a field of the number of layers.

[0178] As one subembodiment of the above embodiment, if the upper layer parameter maxNrpPorts in the PTRS-UplinkConfig configured for the first node is set to “n2”, the actual UL phase tracking reference signal port and associated transmission layer are derived from the indicated TPMI as follows:

[0179] PUSCH antenna ports 1000 and 1002 in the designated TPMI share PT-RS port 0, and PUCH antenna ports 1001 and 1003 in the designated TPMI share PTR-s port 1; UL phase tracking reference signal port 0 is associated with UL layer "x" in the layers transmitted via PUSCH antenna ports 1000 and 1002 in the indicated TPMI, and UL phase tracking reference signal port 1 is associated with UL layer "y" in the layers transmitted via PUSCH antenna ports 1001 and 1003 in the indicated TPMI, where "x" and / or "y" are given by the DCI parameter "PTRS-DMRS Association" in the first signaling.

[0180] In one embodiment, for each cell of the first cell set, there is at least one corresponding precoding information and number of layers field in the first signaling.

[0184] In one embodiment, when the number of bits of the first domain in the first signaling is equal to or greater than 1, whether a transform precoder on at least one cell in the first cell set is enabled is used to indicate the position of the first domain in the first signaling.

[0185] In one embodiment, when the number of bits of the first domain in the first signaling is 1 or more, whether the transform precoder on at least one cell in the first cell set is enabled depends on the number of bits of the first domain in the first signaling. This implicitly indicates the position of the input.

[0186] In one embodiment, when the number of bits of the first domain in the first signaling is 1 or more, according to a predetermined mapping rule, the position of the first domain in the first signaling is determined by the setting of whether a transform precoder on a cell in the first cell set is enabled.

[0187] In one embodiment, if the transform precoder on each cell in the first cell set is enabled, the number of bits of the first domain in the first signaling is equal to 0, and otherwise, the number of bits of the first domain in the first signaling is equal to 1.

FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG. 3 illustrates a radio protocol architecture for a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X), or a control plane 300 between two UEs, 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. The L1 layer is referred to as PHY 301 in this specification. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for links between the first communication node device and the second communication node device and between two UEs via PHY 301. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, a RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Control Protocol) sublayer. The PDCP sublayer 304 includes a Packet Data Convergence Protocol (PDCP) sublayer 304, which terminates in the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and handover support for the first communication node device between the second communication node device. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical channels and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within one 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 Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring lower layers using RRC signaling between the second communication node device and the first communication node device. The radio protocol architecture of the 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 the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, except that the 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 a Service Data Adaptation Protocol (SDAP) sublayer 356, which is responsible for mapping between QoS streams and Data Radio Bearers (DRBs) to support service diversity.

[0214] Embodiment 4 Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0215] The first communication device 410 comprises 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 transmit device / receive device 418, and an antenna 420.

[0216] The second communication device 450 comprises 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 transmit device / receive device 454, and an antenna 452.

[0217] For transmission from the first communication device 410 to the second communication device 450, upper layer data packets from the core network are provided to a controller / processor 475 at the first communication device 410. The controller / processor 475 implements the functions of the L2 layer. For transmission from the first 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 to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for 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). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) in 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-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes them with time-domain and / or frequency-domain reference signals (e.g., pilots), and then performs inverse fast fourier transform (FFT). The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation on the time-domain multi-carrier symbol stream. Each transmitting device 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 a different antenna 420.

[0218] In a transmission from the first communication device 410 to the second communication device 450, each receiving device 454 receives a signal via its corresponding antenna 452. Each receiving device 454 recovers the information modulated onto a radio frequency carrier, converts the radio frequency stream to a baseband multi-carrier symbol stream, and provides the baseband multi-carrier symbol stream to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs analog precoding / beamforming receive operations on the baseband multi-carrier symbol stream from the receiving device 454. The receive processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream subjected to the analog precoding / beamforming receive 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 receive processor 456, and the reference signal is used for channel estimation. After the data signal is detected by multiple antennas in the multi-antenna receive processor 458, any spatial streams destined for the second communication device 450 are recovered. The symbols on each spatial stream are demodulated and restored in the receive processor 456 to generate 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 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 functionality of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes and data. The memory 460 may be referred to as a computer-readable medium.For transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and 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 may also be provided to L3 for L3 processing.

[0219] For transmission from the second communication device 450 to the first communication device 410, upper layer data packets are provided to the controller / processor 459 using the data source 467 in the second communication device 450. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions in the first communication device 410 described for transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for 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. The transmit processor 468 then converts the generated spatial streams into multi-carrier / single-carrier streams. The multi-antenna transmit processor 457 modulates the baseband symbol streams into radio frequency symbol streams, which are provided to different antennas 452 via transmit devices 454 after an analog precoding / beamforming operation in the multi-antenna transmit processor 457. Each transmit device 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides the radio frequency symbol stream to the antenna 452.

[0220] For transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receiving functions at the second communication device 450 described for transmission from the first communication device 410 to the second communication device 450. Each receiving device 418 receives radio frequency signals via its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the functionality of the L1 layer. The controller / processor 475 implements the functionality of the L2 layer. The controller / processor 475 may be associated with a memory 476 that stores program codes and data. The memory 476 may be referred to as a computer-readable medium. For transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover upper layer data packets from the UE 450. The upper layer data packets from the controller / processor 475 can be provided to the core network.
