It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0082] Example 1

[0083] Example 1 illustrates a processing flowchart of the first node according to an embodiment of this application, as shown in Figure 1.

[0084] In Embodiment 1, the first node in this application receives the target DCI in step 101 and sends the target PUSCH in step 102.

[0085] In Example 1, the target DCI indicates target allocation information, and the temporal resource allocation of the target PUSCH depends on the target allocation information; the target PUSCH is used for data transmission; a first type of CSI report is activated, which is a semi-persistent CSI report; whether a first type of CSI report is sent depends on whether the target time window overlaps; the target time window depends on the target allocation information and the target configuration, which is the configuration of the orthogonal sequence of PUSCHs, and the transmission of the target PUSCH depends on the target configuration; the target time window spans a target time slot group, which includes multiple time slots.

[0086] As an example, the target DCI is in DCI (Downlink control information) format.

[0087] As an example, the target DCI is a DCI carried by PDCCH (Physical Downlink Control Channel).

[0088] As an example, the target DCI schedules the target PUSCH.

[0089] As an example, the target PUSCH is a PUSCH.

[0090] As one embodiment, the target DCI indicates target allocation information, including: the time domain resource assignment field in the target DCI indicates the target allocation information.

[0091] As an example, the value of the time-domain resource allocation field in the target DCI is mapped to at least the target allocation information.

[0092] As one embodiment, the target allocation information includes information on symbol allocation within a time slot.

[0093] As an example, the symbols allocated to the target PUSCH within a time slot are determined by the target allocation information.

[0094] As an example, the symbols assigned to the target PUSCH for a single repetition within a time slot are determined by the target allocation information.

[0095] As an example, in this application, the symbols assigned to PUSCH, the symbols used for PUSCH transmission, and the symbols in the time slot are all symbols defined in the time domain.

[0096] As an example, the symbols assigned to PUSCH, the symbols used for PUSCH transmission, and the symbols in the time slot are all OFDM (Orthogonal Frequency Division Multiplexing) symbols.

[0097] As an example, the symbols assigned to PUSCH, and the symbols used for PUSCH transmission, are all symbols in a time slot.

[0098] As an example, the target allocation information includes information on the temporal resource allocation of the target PUSCH.

[0099] As one example, the target allocation information includes information on the starting symbol and allocation length within the time slot.

[0100] As an example, the target allocation information includes SLIV (start and length indicator value).

[0101] As one embodiment, the target allocation information includes SLIV; within a time slot, the starting symbol S relative to the beginning of this time slot, and the number L of consecutive symbols L allocated to the PUSCH starting from the starting symbol S, are determined based on the SLIV:

[0102] If (L-1)≤7, then SLIV=14·(L-1)+S; otherwise, SLIV=14·(14-L+1)+(14-1-S); where, 0 <L≤14-S。

[0103] As an example, in each time slot of the target time slot group, the time domain resources allocated to the target PUSCH include L consecutive symbols counted starting from the starting symbol S in that time slot.

[0104] As an example, in each time slot of the target time slot group, the time-domain resources allocated to a single repetitive transmission of the target PUSCH include L consecutive symbols counted from the starting symbol S in that time slot.

[0105] As an example, the transmission of the target PUSCH includes multiple repeated transmissions of the target PUSCH.

[0106] As an example, the target PUSCH is transmitted at least across the target time slot group.

[0107] As an example, each time slot in the target time slot group is used for the transmission of the target PUSCH.

[0108] As an example, when one of the time slots in the target time slot group includes a symbol(s) for transmitting the target PUSCH, the one time slot in the target time slot group is used for the transmission of the target PUSCH.

[0109] As an example, the first node performs one repeated transmission of the target PUSCH in each time slot of the target time slot group.

[0110] As one embodiment, the target PUSCH is used for data transmission, including: at least one transport block is transmitted on the target PUSCH.

[0111] As an example, the target PUSCH is used to transmit a first transport block, which is repeatedly transmitted multiple times across the target time slot group.

[0112] As an example, the target PUSCH is used to transmit a first transport block; in each time slot of the target time slot group, the first transport block is transmitted after undergoing at least the following processes: CRC attachment, code block segmentation and code block CRC attachment, channel coding, rate matching, code block concatenation, scrambling, modulation, layer mapping, transform precoding, precoding, mapping to virtual resource blocks, and mapping from virtual to physical resource blocks.

[0113] As one embodiment, the first transport block includes data from UL-SCH (Uplink Shared Channel(s)).

[0114] As an example, the first node performs a single retransmission of the target PUSCH in each time slot of the target time slot group.

[0115] As an example, the activation of the first type of CSI report includes: the activation of the reporting configuration corresponding to the first type of CSI report.

[0116] As an example, the first type of CSI report is activated by physical layer signaling.

[0117] As an example, the first type of CSI report is activated by DCI.

[0118] As an example, the first node receives a DCI format that activates the first type of CSI report.

[0119] As an example, the first node receives a DCI format in which the CSI request field indicates the activation of the first type of CSI report.

[0120] As an example, the DCI format for activating the first type of CSI report is sent by the second node in this application.

[0121] As an example, the DCI format of the CSI report activating the first type is sent before the target DCI.

[0122] As an example, the first type of CSI report can only be sent when the system is active.

[0123] As an example, the first type of CSI report is a semi-persistent CSI report that is reported via PUSCH.

[0124] As an example, the first type of CSI report is a semi-persistent CSI report that will be sent on the PUSCH.

[0125] As an example, the first node has a semi-persistent CSI report to report.

[0126] As an example, for a CSI report of the first type, the corresponding PUSCH is the PUSCH that carries the CSI report of the first type.

[0127] As an example, an overlap of a CSI report of the first type with the target time window means that the PUSCH including this CSI report of the first type will overlap with the target time window in the time domain.

[0128] As an example, the data transmission of the target PUSCH and the first type of CSI report are on the same carrier.

[0129] As an example, the target PUSCH and the PUSCH for carrying the first type of CSI report are on the same carrier.

[0130] As an example, the first CSI report is the first type of CSI report, and whether the first CSI report is sent depends on whether the first CSI report overlaps with the target time window.

[0131] As an example, the first CSI report is the first type of CSI report; when the first CSI report overlaps with the target time window, the probability of the first CSI report being sent is K1; when the first CSI report does not overlap with the target time window, the probability of the first CSI report being sent is K2; K1 is greater than 0 and less than 1, K2 is greater than 0 and less than 1, and K1 is less than K2.

[0132] As an example, the first CSI report is the first type of CSI report; when the first CSI report overlaps with the target time window, the probability of the first CSI report being sent is K1; when the first CSI report does not overlap with the target time window, the probability of the first CSI report being sent is K2; K1 is greater than 0 and less than 1, K2 is greater than 0 and less than 1, and K1 is greater than K2.

[0133] As an example, K1 is equal to 0.5.

[0134] As an example, K1 is equal to 0.75.

[0135] As an example, K2 is configurable.

[0136] As an example, K2 is equal to K1 plus a predefined constant.

[0137] As an example, both K1 and K2 are configurable.

[0157] As an example, the time-domain resources in the target time window are continuous in the time domain.

[0158] As an example, the target time window includes time-domain resources for multiple repeated transmissions of the target PUSCH.

[0159] As an example, the start of the target time window depends on the target allocation information, and the end of the target time window depends on the target configuration.

[0160] As an example, the target allocation information implicitly indicates the start of the target time window, and the target configuration implicitly indicates the end of the target time window.

[0161] As an example, the symbols within the time slots where the start and end of the target time window are located are determined by the target allocation information, and the target time slot group depends on the target configuration.

[0162] As one embodiment, the target time window spans a target time slot group, including: the target time window includes at least a portion of the first time slot in the target time slot group, at least a portion of the last time slot in the target time slot group, and all other time slots in the target time slot group.

[0184] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and control plane according to this application, as shown in Figure 3. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3 shows the radio protocol architecture for a first communication node device (UE, gNB, or V2X (Vehicle to Everything) RSU (Road Side Unit), on-board equipment, or on-board communication module) and a second communication node device (gNB, UE, or V2X RSU, on-board equipment, or on-board communication module), or the control plane 300 between two UEs, 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) 305 sits above PHY 301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY 301. L2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link 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-region mobility between the second and first communication node devices. 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). 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 among the first communication node devices. 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 acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second and first communication node devices.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.).

[0189] Example 4

[0190] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to this 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0215] Example 5

[0216] Example 5 illustrates a signal transmission flowchart according to an embodiment of this application, as shown in Figure 5. In Figure 5, the first node U1 and the second node U2 communicate via an air interface. Specifically, in Figure 5, the steps in the dashed box F1 exist only under specific conditions; and the order of the steps in the dashed box F1 with other steps does not represent a specific temporal relationship.

[0217] The first node U1 receives the target DCI in step S511; sends the target PUSCH in step S512; and sends the first CSI report in step S513.

[0218] The second node U2 sends the target DCI in step S521; receives the target PUSCH in step S522; and receives the first CSI report in step S523.

[0219] In Example 5, the target DCI indicates target allocation information, and the temporal resource allocation of the target PUSCH depends on the target allocation information; the target PUSCH is used for data transmission.

[0220] A first type of CSI report is activated, which is a semi-persistent CSI report; whether a first type of CSI report is sent depends on whether the target time window overlaps; the first CSI report is the first type of CSI report; when a first set of conditions is met, the first CSI report is not sent; the first set of conditions includes: the first CSI report overlaps with the target time window;

[0221] The target time window depends on the target allocation information and the target configuration, where the target configuration is the configuration of the orthogonal sequence of the PUSCH, and the transmission of the target PUSCH depends on the target configuration. The target time window spans a target time slot group, which includes multiple time slots. The first symbol is the starting symbol relative to the start of the time slot, as determined by the target allocation information, and the second symbol is the Lth symbol counted from the first symbol within the time slot, where L is determined by the target allocation information. The target time window starts from the first symbol in the first time slot of the target time slot group and ends with the second symbol in the last time slot of the target time slot group. The first length is the length of the orthogonal sequence of the PUSCH, and the first length depends on the target configuration. The number of time slots in the target time slot group is equal to the first length. Each time slot in the target time slot group includes symbols for the transmission of the target PUSCH.

[0222] As a sub-example of Example 5, the target time window contains time-domain resources that are not used for the transmission of the target PUSCH.

[0223] As a sub-example of Example 5, the transmission of the target PUSCH includes: performing a repeated transmission of the target PUSCH at least once in each time slot of the target time slot group.

[0224] As a sub-example of Example 5, the target time slot group is one of a plurality of time slot groups; each of the plurality of time slot groups includes a plurality of time slots, and each of the plurality of time slot groups is used for the transmission of the target PUSCH.

[0225] As an example, the first node U1 is the first node in this application.

[0226] As an example, the second node U2 is the second node in this application.

[0227] As an example, the first node U1 is a UE.

[0228] As one example, the second node U2 is a base station.

[0229] As one embodiment, the air interface between the second node U2 and the first node U1 is the Uu interface.

[0230] As one embodiment, the air interface between the second node U2 and the first node U1 includes a cellular link.

[0231] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between the base station equipment and the user equipment.

[0232] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between satellite equipment and user equipment.

[0233] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between the relay device and the user equipment.

[0234] As one example, the target configuration is configured by the second node to the first node.

[0235] As an example, when the first set of conditions is satisfied, the step in the dashed box F1 does not exist.

[0236] As an example, when the step in dashed box F1 is present, the step in dashed box F1 can be before or after the transmission / reception of the target DCI.

[0237] As an example, when the step in dashed box F1 is present, the step in dashed box F1 can be before or after the transmission / reception of the target PUSCH.

[0238] As an example, in this application, the sending (or non-sending) of a CSI report of the first type means that the first node sends (or does not send) the CSI report of the first type.

[0239] As an example, when the second node determines, according to the agreement between the two communicating parties, that a CSI report of the first type will not be sent, the second node U2 does not need to perform the reception of this CSI report of the first type.

[0240] As an example, the advantages of the above method include: it helps to reduce the receiving overhead of the CSI report receiver.

[0241] As an example, when the first CSI report is sent: the bits of the first CSI report are sent on the corresponding PUSCH after undergoing at least the following processes: CRC attachment, code block segmentation and code block CRC attachment, channel coding, rate matching, code block concatenation, scrambling, modulation, layer mapping, transform precoding, precoding, mapping to virtual resource blocks, and mapping from virtual to physical resource blocks.

[0242] As one embodiment, the second node U2 receiving the first CSI report includes: the second node U2 performing reception on the corresponding PUSCH, and processing and decoding the received signal before sending it to the first CSI report.

[0243] As an example, apart from modulation symbols and complex value symbols, all symbols mentioned in this application are time-domain defined symbols.

[0245] As an example, apart from modulation symbols and complex value symbols, all symbols mentioned in this application are time slot symbols.

[0246] As an example, the first type of CSI report is activated before the transmission of the target DCI.

[0247] As one embodiment, the second node U2 receiving the target PUSCH includes: the second node U2 receiving the first transport block.

[0248] As one embodiment, the second node U2 receiving the target PUSCH includes: the second node U2 performing one reception for the target PUSCH (one repetition) in each time slot of at least the target time slot group.

[0249] As an example, the first transport block is received via the target PUSCH.

[0250] As an example, the second node U2 receives signals carrying the first transport block on the target PUSCH (multiple repetitions) in multiple time slots, merges all the received signals carrying the first transport block, and performs at least decoding to obtain the first transport block.

[0251] As an example, the transmission of the target PUSCH is generated according to the agreement rules between the communicating parties, and the second node U2 determines on its own how to perform the reception of the first transport block (carried by the target PUSCH) transmitted across multiple time slots.

[0252] Example 6

[0253] Example 6 illustrates a schematic diagram of a target time slot group and a target time window according to an embodiment of this application, as shown in Figure 6. In Figure 6, the gray-filled portion (including a plain gray-filled portion, a diagonal-lined portion, and a horizontal and vertical-lined portion) in each time slot of the target time slot group represents the time-domain resources allocated to the target PUSCH; wherein, the diagonal-lined portion in the gray-filled portion of each time slot of the target time slot group represents the first symbol in the corresponding time slot, and the horizontal and vertical-lined portion in the gray-filled portion of each time slot of the target time slot group represents the second symbol in the corresponding time slot.

[0254] In Embodiment 6, the first symbol is the starting symbol relative to the start of the time slot determined by the target allocation information, and the second symbol is the Lth symbol counted from the first symbol within the time slot, where L is determined by the target allocation information; the target time window starts from the first symbol in the first time slot of the target time slot group and ends at the second symbol in the last time slot of the target time slot group.

[0255] In Example 6, the target time slot group includes 4 time slots.

[0256] As an example, in Figure 6, the portion of the target time window other than the gray-filled portion is not used for the transmission of the target PUSCH.

[0257] As an example, in Figure 6, the gray-filled portion in each time slot of the target time slot group includes multiple symbols.

[0258] As an example, the symbols allocated to the target PUSCH in one slot of the target time slot group are a repeating symbol allocated to the target PUSCH.

[0259] As an example, the symbols allocated to the target PUSCH in one time slot of the target time slot group are used to transmit one repetition of the target PUSCH.

[0260] As an example, each repetition of the target PUSCH carries the first transport block.

[0261] As an example, the number of symbols allocated to the target PUSCH is the same in any two time slots of the target time slot group.

[0262] As an example, the symbols assigned to the target PUSCH in any two time slots of the target time slot group are the same.

[0263] As an example, both the first symbol and the second symbol are relative to the time slot in which they are located.

[0264] As an example, L is equal to the number of consecutive symbols counted starting from the first symbol.

[0265] As one embodiment, the target allocation information includes SLIV; within a time slot, the starting symbol S (i.e., the first symbol) relative to the beginning of this time slot, and the number L of consecutive symbols L allocated to the PUSCH starting from the starting symbol S, are determined according to the SLIV:

[0266] If (L-1)≤7, then SLIV=14·(L-1)+S; otherwise, SLIV=14·(14-L+1)+(14-1-S); where, 0 <L≤14-S。

[0267] As an example, the first symbol is symbol S, and the second symbol is symbol S+L-1.

[0268] As a sub-implementation of the above embodiment, S and S+L-1 both represent the symbol index within a time slot, and the symbol index within a time slot starts from 0.

[0269] As an example, both the first symbol and the second symbol are time-domain defined symbols.

[0270] As an example, both the first symbol and the second symbol are OFDM symbols.

[0271] As an example, both the first symbol and the second symbol are symbols in a time slot.

[0272] As an example, the target time window begins at the start of the first symbol in the first time slot of the target time slot group.

[0273] As an example, the first time slot in the target time slot group is the earliest time slot in the target time slot group.

[0274] As an example, the target time window ends at the end of the second symbol in the last time slot of the target time slot group.

[0275] As an example, the last time slot in the target time slot group is the latest time slot in the target time slot group.

[0276] As an example, the number of time slots in the target time slot group is equal to 2.

[0277] As an example, the number of time slots in the target time slot group is no more than 8.

[0278] As an example, the advantages of the above method include: reducing system design complexity.

[0279] As an example, the number of time slots in the target time slot group is no more than 1024.

[0280] As an example, the first length is the length of the orthogonal sequence of PUSCH, and the first length depends on the target configuration; the number of time slots in the target time slot group is equal to the first length.

[0281] As an example, the target configuration indicates the first length.

[0282] As an example, the target configuration includes the configuration of a first orthogonal sequence, which is an orthogonal sequence of PUSCH, and the first length is the length of the first orthogonal sequence.

[0283] As an example, the first orthogonal sequence is an orthogonal sequence used for PUSCH transmission.

[0284] As an example, the first orthogonal sequence is used for the transmission of the target PUSCH.

[0285] As an example, the target configuration indicates the length of the first orthogonal sequence.

[0286] As an example, the target configuration indicates the first orthogonal sequence.

[0287] As an example, the target configuration indicates the index of the first orthogonal sequence.

[0288] As an example, the first orthogonal sequence is one of a plurality of orthogonal sequences, each of which corresponds to an index.

[0289] As an example, the number of time slots in the target time slot group is equal to the length of the orthogonal sequence of PUSCHs indicated by the target configuration.

[0290] As an example, the first length is equal to K as stated in this application.

[0291] Example 7

[0292] Example 7 illustrates a schematic diagram of whether a first type of CSI report is sent according to an embodiment of this application, depending on whether the target time window overlaps, as shown in Figure 7.

[0293] In Example 7, the first CSI report is the first type of CSI report; when the first set of conditions is met, the first CSI report is not sent; the first set of conditions includes: the first CSI report overlaps with the target time window.

[0294] As an example, in this application, the overlap of a CSI report of the first type with the target time window refers to the overlap in the time domain.

[0295] As an example, in this application, the absence of overlap between a CSI report of the first type and the target time window means that there is no overlap in the time domain.

[0296] As an example, the first CSI report is a semi-persistent CSI report to be carried on the PUSCH.

[0297] As an example, the first CSI report overlaps with the target time window in the time domain when the first CSI report overlaps with the target time window in at least one symbol.

[0298] As a sub-example of the above embodiment, when the first CSI report and the target time window do not overlap in the time domain in any symbol, the first CSI report and the target time window do not overlap.

[0299] As an example, when the PUSCH for carrying the first CSI report overlaps with the target time window in the time domain, the first CSI report overlaps with the target time window.

[0300] As a sub-example of the above embodiment, when the PUSCH for carrying the first CSI report does not overlap with the target time window in the time domain, the first CSI report does not overlap with the target time window.

[0301] As an example, the first CSI report overlaps with the target time window when the PUSCH carrying the first CSI report overlaps with the target time window in at least one symbol in the time domain.

[0302] As a sub-example of the above embodiment, when the PUSCH for carrying the first CSI report does not overlap with the target time window in any symbol in the time domain, the first CSI report does not overlap with the target time window.

[0303] As an example, the overlap between the first CSI report and the target time window means that the PUSCH including the first CSI report would overlap with the target time window in the time domain.

[0304] As a sub-example of the above embodiment, the fact that the first CSI report does not overlap with the target time window means that the PUSCH including the first CSI report will not overlap with the target time window in the time domain.

[0305] As one embodiment, the first CSI report not being sent includes: the first node shall not send the first CSI report.

[0306] As one embodiment, the first CSI report not being sent includes: the first node not sending the first CSI report on the PUSCH that is intended to carry the first CSI report.

[0307] As one embodiment, the first CSI report is not sent, including: the first node does not send the PUSCH for carrying the first CSI report.

[0308] As an example, the PUSCH that carries the first CSI report is a PUSCH that includes the first CSI report.

[0309] As an example, the PUSCH for carrying the first CSI report is the PUSCH allocated for sending the first CSI report.

[0310] As an example, the first CSI report will be sent on the PUSCH that carries the first CSI report.

[0311] As an example, the first set of conditions includes only one condition.

[0312] As an example, the first set of conditions includes only the overlap between the first CSI report and the target time window.

[0313] As an example, the first set of conditions includes multiple conditions.

[0314] As an example, the first set of conditions being satisfied means that each condition in the first set of conditions is satisfied.

[0315] As an example, the first set of conditions also includes a timeline condition.

[0316] As an example, the first set of conditions also includes a timeline condition relating to the last symbol of the target DCI.

[0317] As an example, the first timeline condition is one of the conditions in the first set of conditions; the first timeline condition is: the earliest symbol of the PUSCH carrying the first CSI report and the target PUSCH starts no earlier than N2+d2 symbols after the last symbol of the target DCI; wherein, N2 is the PUSCH preparation time in terms of the number of symbols, and d2 is configurable.

[0318] As an example, N2 is configurable.

[0319] As an example, N2 is described in Table 6.4-1 of 3GPP TS 38.214.

[0320] As an example, d2 is the larger of d0 and d1, d0 is one of 0 or 1 and is configurable, and d1 is one of 0 or 1 and is configurable.

[0321] As an example, if the first symbol assigned to the PUSCH for carrying the first CSI report consists only of DM-RS (Demodulation Reference Signal), then d0 equals 0; otherwise, d0 equals 1.

[0322] As an example, if the first symbol assigned to the target PUSCH consists only of DM-RS, then d1 equals 0; otherwise, d1 equals 1.

[0323] As an example, to ensure that the earliest symbol of the PUSCH carrying the first CSI report and the target PUSCH starts no earlier than N2+d2 symbols after the last symbol of the target DCI, the following is included:

[0324] The reference symbol is used to carry either the earliest symbol of the PUSCH in the first CSI report or the earliest symbol of the target PUSCH, and the reference symbol is no later than the earliest symbol of the PUSCH in the first CSI report or the earliest symbol of the target PUSCH; the reference symbol starts after the last symbol of the target DCI, and is spaced at least N2+d2 symbols apart from the end of the last symbol of the target DCI.

[0325] As an example, if the first timeline condition is not met, it is considered an error condition.

[0326] As an example, the first CSI report is sent when the second set of conditions is met.

[0327] As one embodiment, the first CSI report is sent by the first node on the PUSCH that carries the first CSI report.

[0328] As one embodiment, the first CSI report is sent by the first node, which includes sending the PUSCH to carry the first CSI report.

[0329] As an example, the first CSI report is sent, and the PUSCH carrying the first CSI report is sent only in one time slot.

[0330] As an example, the second set of conditions includes at least one condition.

[0331] As one embodiment, the second set of conditions includes conditions related to time-domain resource allocation.

[0332] As an example, the second set of conditions includes conditions related to the temporal resource allocation of the first CSI report.

[0333] As one embodiment, the second set of conditions includes: the first CSI report does not overlap with the target time window.

[0334] As one example, the second set of conditions includes: the first CSI report does not overlap with a specific type of time window.

[0335] As an example, the target time window is any of the specific types of time windows.

[0336] As one example, the second set of conditions includes multiple conditions.

[0337] As an example, the second set of conditions being satisfied means that each condition in the second set of conditions is satisfied.

[0338] As an example, the second set of conditions further includes: the first CSI report does not overlap in the time domain with any DCI-scheduled PUSCH other than the target PUSCH.
