The time domain allocation length is equal to the sum of the index of the orthogonal sequence of PUSCH indicated by the first configuration and 3, rounded to the 1.1th direction, and is the earliest PUSCH that does not overlap with the first PUCCH in the time domain.

[0164] Example 3

[0165] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. 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 for the control plane 300 between the first communication node device (UE, gNB, or V2X (Vehicle to Everything) RSU, on-board equipment, or on-board communication module) and the second communication node device (gNB, UE, or V2X RSU, on-board equipment, or on-board communication module), or between two UEs, is illustrated using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (RadioLink Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second communication node device and the first communication node device.The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). 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 packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams 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., the IP (Internet Protocol) 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.).

[0173] Example 4

[0174] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in the access network.

[0175] The first communication device 410 includes a controller / processor 475, a memory 476, 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.

[0176] The second 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.

[0177] In the 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 L2 layer functionality. In the transmission from the first communication device 410 to the second 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 retransmitting 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 mapping of signal clusters 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)). 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 to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an 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 multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0178] 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 spatial stream destined for the second 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 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 transmission from the first communication device 410 to the second 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 upper-layer data packets from the core network. 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.

[0179] 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 functions at the first communication device 410 described in the 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, 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 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 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.

[0180] 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. In the transmission from the second communication device 450 to the first 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 upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0359] Example 10

[0360] Example 10 illustrates a schematic diagram of a first set of conditions according to an embodiment of this application, as shown in the attached diagram. Figure 10 As shown.

[0361] In Example 10, the first set of conditions includes multiple timeline conditions, one of which is that the reference symbol is not preceded by a symbol after a first duration following the last symbol of any PDCCH in the first PDCCH set where the cyclic prefix begins.

[0366] As an example, when a HARQ-ACK (Hybrid Automatic Repeat Request Acknowledgement) corresponding to a PDSCH is transmitted on the first PUCCH, this PDSCH is the PDSCH corresponding to the first PUCCH.

[0367] As an example, when a scheduling signaling of a PDSCH indicates that HARQ-ACK information for a transport block in the first PUCCH is sent on the first PUCCH, the PDSCH is the PDSCH corresponding to the first PUCCH.

The κ=T s / T c =64,T s =1 / (Δf) ref ·N f,ref ),Δf ref =15·10 3 Hz and N f,ref =2048.

[0371] As an example, the time-domain allocation of the i-th PDSCH indicates the d 1,1 .

[0372] As an example, the d 1,1 It is the time-domain allocation function of the i-th PDSCH, and this function is predefined.

[0373] As an example, the multiple timeline conditions include the following timeline condition: the reference symbol is not before a symbol after a third duration following the last symbol of the PDCCH corresponding to the first PUCCH, where the third duration depends on the SCS configuration.

[0374] As an example, when a PDCCH provides a DCI format with a non-scheduled PDSCH and a corresponding HARQ-ACK transmission on the first PUCCH, this PDCCH is the PDCCH corresponding to the first PUCCH.

[0375] As an example, when a PDCCH provides a DCI format with corresponding HARQ-ACK information and does not schedule a PDSCH, and indicates that the corresponding HARQ-ACK information is sent on the first PUCCH, this PDCCH is the PDCCH corresponding to the first PUCCH.

[0376] As an example, when the first node is about to send the corresponding HARQ-ACK information of the DCI format of the unscheduled PDSCH provided by the PDCCH on the first PUCCH, this PDCCH is the PDCCH corresponding to the first PUCCH.

[0377] As an example, the third duration is The maximum value in;

[0378] Wherein, for the i-th PDCCH corresponding to the first PUCCH, The N depends on the SCS configuration μ; the μ corresponds to the smallest SCS configuration in the third SCS configuration set; the third SCS configuration set includes SCS configurations for air interface resource pools in the target air interface resource pool set, and SCS configurations for the i-th PDCCH; the T c =1 / (Δf) max ·N f ), Δf max =480·10 3 Hz and N f =4096. The κ=Ts / T c =64,T s =1 / (Δf) ref ·N f,ref ),Δf ref =15·10 3 Hz and N f,ref =2048.

[0379] As an example, the SCS configuration μ indicates the N.

[0380] As an example, N is a function of the SCS configuration μ, which is predefined.

[0381] As an example, N=5 is used for μ=0, N=5.5 is used for μ=1, and N=11 is used for μ=2.

[0382] As an example, N=10 is used for μ=0, N=12 is used for μ=1, N=22 is used for μ=2, N=25 is used for μ=3, N=100 is used for μ=5, and N=200 is used for μ=6.

[0386] As an example, the last symbol of a PDCCH is the latest symbol occupied in the time domain of that PDCCH.

[0387] As an example, the reference symbol is not preceded by a symbol after a first duration following the last symbol of any PDCCH in the first PDCCH set, where the cyclic prefix begins.

[0388] As an example, the reference symbol does not begin before the symbol whose cyclic prefix begins after the first duration following the last symbol of any PDCCH in the first PDCCH set.

[0389] As an example, the symbol after the first duration following the last symbol of any PDCCH in the first PDCCH set, where the cyclic prefix begins, refers to the earliest OFDM symbol that satisfies the condition that the cyclic prefix begins after the first duration following the last symbol of any PDCCH in the first PDCCH set.

[0390] As an example, the first set of conditions includes multiple timeline conditions, and one of the timeline conditions in the first set of conditions includes at least: the reference symbol is not before a symbol after a first duration following the last symbol of the PDCCH that provides the first signaling, where the first duration depends on the SCS configuration.

[0391] As an example, the symbol after the first duration following the last symbol of the PDCCH providing the first signaling, where the cyclic prefix begins, refers to the earliest OFDM symbol that satisfies the condition that the cyclic prefix begins after the first duration following the last symbol of the PDCCH providing the first signaling.

[0392] As an example, the start of the reference symbol is no earlier than the start of the symbol after the first duration following the start of the cyclic prefix after the last symbol of any PDCCH in the first PDCCH set.

[0393] As an example, the cyclic prefix begins after the first duration following the last symbol of any PDCCH in the first PDCCH set, and the symbol after that duration has the same duration as the last symbol of any PDCCH in the first PDCCH set.

[0394] As an example, the duration of the symbol following the first duration after the last symbol of any PDCCH in the first PDCCH set is different from the duration of the last symbol of any PDCCH in the first PDCCH set.

[0395] As an example, the cyclic prefix starting after the first duration following the last symbol of any PDCCH in the first PDCCH set is an uplink symbol.

[0396] As an example, the reference symbol is an uplink symbol.
