Description

Technical Field

[0001] 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

[0002] In traditional wireless communication, terminals supporting carrier aggregation technology can transmit and receive on multiple cells. Carrier aggregation technology can enable terminals to obtain greater service bandwidth and higher transmission rates, but its utilization efficiency of fragmented spectrum resources is not high. Supporting the configuration of multiple carriers in the same cell can not only obtain greater service bandwidth and higher transmission rates, but also effectively improve the utilization efficiency of fragmented spectrum resources and reduce base station energy consumption.

[0003] UCI (Uplink Control Information) multiplexing is an important technology in mobile communications. This technology helps to avoid the simultaneous transmission of some uplink channels that are scattered in the frequency domain, making it easier to achieve radio frequency indicators such as out-of-band emission. Summary of the Invention

[0004] For systems supporting multiple frequency blocks within the same cell, how to achieve UCI reuse is a worthwhile research problem in system design. This application discloses a solution to address this problem. It should be noted that although the motivation for this application primarily stems from scenarios supporting multiple carriers within the same cell (different frequency blocks can be on different carriers), this application is also applicable to other scenarios supporting multiple frequency blocks within the same cell. Furthermore, adopting a unified solution for different scenarios can reduce implementation complexity or cost, or improve performance. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0005] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the TS38 series of specification protocols of 3GPP (3rd Generation Partner Project).

[0136] Example 3

[0137] 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 user node equipment (UE or RSU in V2X, onboard equipment or onboard communication module) and network node equipment (gNB, UE or RSU in V2X, onboard equipment or onboard communication module), 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the links between the user node equipment and network node equipment, as well as between two UEs, through PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the network node equipment. PDCP sublayer 304 provides data encryption and integrity protection, and also supports cross-cell mobility between user node devices and network node devices. RLC sublayer 303 provides packet segmentation and reassembly, implements retransmission of lost packets through ARQ, and also provides duplicate packet detection and protocol error detection. MAC sublayer 302 provides mapping between logical and transport channels and multiplexing of logical channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among user node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (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 network node devices and user 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 user node devices and network 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 streams and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the user 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., remote UE, server, etc.).

[0138] As an example, Appendix Figure 3 The wireless protocol architecture described herein is applicable to the first node in this application.

[0139] As an example, Appendix Figure 3 The wireless protocol architecture described herein is applicable to the second node in this application.

[0140] As an example, the first node and the second node in this application are the user node device and the network node device in Example 3, respectively.

[0141] As an example, an uplink channel in this application is generated in the PHY351.

[0142] As an example, a physical layer signaling in this application is generated in the PHY301.

[0143] Example 4

[0144] Example 4 illustrates a hardware module schematic diagram of a communication node according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0145] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0146] The second 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.

[0147] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs channel coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, 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-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 spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses 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.

[0148] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses 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 first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then deinterleaves and decodes the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the second node 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.

[0149] In the transmission from the first communication device 450 to the second communication device 410, at the first 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 second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between 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 second communication device 410. Transmit processor 468 performs channel coding, interleaving, and modulation mapping. Multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. 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.

[0150] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer 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 first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0163] As an example, the first communication device 450 is the first node in this application.

[0164] As an example, the second communication device 410 is the second node in this application.

[0165] As an example, the first communication device 450 is a UE, and the second communication device 410 is a base station.

[0166] As an example, at least one of {the antenna 452, the receiver 454, the multi-antenna receiving processor 458, the receiving processor 456, the controller / processor 459, the memory 460, and the data source 467} is used to receive the plurality of physical layer signaling in this application.

[0167] As an example, at least one of {the antenna 420, the transmitter 418, the multi-antenna transmitter processor 471, the transmitter processor 416, the controller / processor 475, and the memory 476} is used to transmit the plurality of physical layer signaling in this application.

[0168] As an example, at least one of {the antenna 452, the transmitter 454, the multi-antenna transmitter processor 457, the transmitter processor 468, the controller / processor 459, the memory 460, and the data source 467} is used to transmit the first UCI in this application.

[0169] As an example, at least one of {the antenna 420, the receiver 418, the multi-antenna receiver processor 472, the receiver processor 470, the controller / processor 475, and the memory 476} is used to receive the first UCI in this application.

[0170] Example 5

[0171] Example 5 illustrates a transmission flowchart between a first node and a second node according to an embodiment of this application, as shown in the attached diagram. Figure 5 As shown. In particular, the steps in the dashed box F1 are optional.

[0172] The first node U1 receives multiple physical layer signaling messages in step S510 and sends the first UCI in step S511.

[0173] The second node U2 sends multiple physical layer signaling messages in step S520 and receives the first UCI in step S521.

[0174] In Embodiment 5, the first UCI is multiplexed into one of the multiple uplink channels for transmission. The multiplexing of the first UCI depends on the cell index and the frequency block group index. Each of the multiple uplink channels is on a frequency block group. The frequency block group in which the uplink channel used to multiplex the first UCI is located is the frequency block group with the smallest index included by the cell with the smallest index. A cell includes at least one frequency block group, and a frequency block group includes at least one frequency block included by the cell to which it belongs. The frequency block group included by a cell is configurable.

[0175] The plurality of uplink channels overlap with the first PUCCH in the time domain. The first PUCCH is the uplink control channel for carrying the first UCI. Each of the plurality of uplink channels is scheduled by one of the plurality of physical layer signaling. Each of the plurality of uplink channels is a PUSCH.

[0176] As a sub-example of Example 5, when at least two of the plurality of uplink channels are on the frequency block group with the smallest index included in the cell with the smallest index, the uplink channel used for multiplexing the first UCI is the earliest uplink channel among the at least two uplink channels.

[0177] As a sub-example of Example 5, one of the multiple uplink channels spans multiple frequency blocks, and the multiple frequency blocks correspond to different time domain configurations; the time domain allocation of the one uplink channel among the multiple uplink channels is determined according to a reference time domain configuration, which is one of the different time domain configurations.

[0178] The two sub-examples of Example 5 can be combined.

[0179] As an example, the first node U1 is the first node in this application.

[0180] As an example, the second node U2 is the second node in this application.

[0181] As an example, the first node U1 is a UE.

[0182] As one example, the second node U2 is a base station.

[0183] As one embodiment, the air interface between the second node U2 and the first node U1 is the Uu interface.

[0184] As one embodiment, the air interface between the second node U2 and the first node U1 includes a cellular link.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] As one embodiment, the first node transmits each of the plurality of uplink channels, and the second node receives each of the plurality of uplink channels.

[0189] It should be noted that sending (or receiving) a channel is a common expression in this field, meaning sending (or receiving) on ​​this channel, or sending (or receiving) signals on this channel; the above expression is beneficial for maintaining consistency with the general expression in this field.

[0190] As an example, there is a one-to-one correspondence between the plurality of uplink channels and the plurality of physical layer signaling.

[0191] As an example, one of the multiple physical layer signaling protocols is DCI (Downlink Control Information).

[0192] As an example, one of the multiple physical layer signaling protocols is in DCI format.

[0193] As an example, each of the plurality of uplink channels is dynamically scheduled by one of the plurality of physical layer signaling methods.

[0194] As an example, for one of the plurality of uplink channels, the corresponding physical layer signaling indicates the frequency domain resources allocated to this uplink channel.

[0195] As an example, for one of the plurality of uplink channels, the corresponding physical layer signaling indicates the time-domain resources allocated to this uplink channel.

[0196] As an example, the steps in the dashed box F1 are present.

[0197] As an example, the step in the dashed box F1 does not exist.

[0198] Example 6

[0199] Example 6 illustrates a schematic diagram according to an embodiment of this application for explaining the minimum index frequency block group included in the minimum index cell and the uplink channel for reusing the first UCI, as shown in the attached diagram. Figure 6 As shown.

[0200] In embodiment 6, the plurality of uplink channels are three uplink channels: uplink channel #1, uplink channel #2, and uplink channel #3; uplink channel #j is on frequency block group #j included in cell #j (where j can be any value of 1, 2, or 3).

[0201] The following examples illustrate the minimum index frequency block group included in the cell with the minimum index and the uplink channel used for reusing the first UCI.

[0202] Case 1: The index of cell #1 is less than the index of cell #2, and the index of cell #2 is less than or equal to the index of cell #3 (when the index of cell #2 is equal to the index of cell #3, cell #2 and cell #3 are the same cell); the cell with the smallest index is cell #1, and the frequency block group with the smallest index included in the cell with the smallest index is frequency block group #1 included in cell #1 (in this case, cell #1 only includes one frequency block group (i.e., frequency block group #1), and the frequency block group with the smallest index included in the cell with the smallest index is frequency block group #1), and the uplink channel used for multiplexing the first UCI is uplink channel #1.

[0203] Case 2: The index of cell #1 is equal to the index of cell #2 (in this case, cell #1 and cell #2 are the same cell), the index of cell #3 is greater than the index of cell #1, and the index of frequency block group #1 is greater than the index of frequency block group #2; the cell with the smallest index is cell #2, the frequency block group with the smallest index included in the cell with the smallest index is frequency block group #2 included in cell #2, and the uplink channel used for multiplexing the first UCI is uplink channel #2.

[0204] Case 3: The indices of cell #1, cell #2, and cell #3 are the same (in this case, cell #1, cell #2, and cell #3 are the same cell); the index of frequency block group #1 is greater than the index of frequency block group #2, and the index of frequency block group #2 is greater than the index of frequency block group #3; the frequency block group with the smallest index included in the cell with the smallest index is frequency block group #3 included in cell #3, and the uplink channel used for multiplexing the first UCI is uplink channel #3.

[0205] It should be noted that the solution disclosed in this application is a general solution that is applicable to at least all of the above situations.

[0206] Without loss of generality, Example 6 is illustrated using the case of three uplink channels; the scheme disclosed in this application is also applicable to cases where there are two uplink channels or more than three uplink channels.

[0207] As one embodiment, the plurality of uplink channels can be two uplink channels or more than three uplink channels.

[0208] As an example, each of the multiple uplink channels may include more than one frequency block group within its cell.

[0209] As an example, the index of a cell can be configured or determined according to a predefined sorting rule.

[0210] As an example, the index of a frequency block group is configurable or determined according to a predefined sorting rule.

[0211] As an example, determining the frequency block group with the smallest index included in the cell with the smallest index only requires considering the frequency block group used to transmit at least one of the plurality of uplink channels and the cells to which these frequency block groups belong.

[0212] As an example, the index of a cell is the cell index.

[0213] As an example, the index of a frequency block group is the frequency block group index.

[0214] As an example, for the cell with the smallest index, the corresponding index is the smallest index in the first index set;

[0215] The first index set includes the index of the cell where each of the plurality of uplink channels is located; and for each index in the first index set, at least one of the plurality of uplink channels exists in the corresponding cell.

[0216] As an example, when an uplink channel is on a frequency block group included in a cell, the uplink channel is on that cell.

[0217] As an example, an uplink channel does not span multiple cells.

[0218] As an example, the indexes in the first index set are all cell indexes.

[0219] As an example, for the frequency block group with the smallest index included in the cell with the smallest index, the corresponding index is the smallest index in the second index set;

[0220] The second index set includes the index of the frequency block group where each uplink channel in the cell with the smallest index is located; and for each index in the second index set, there is at least one uplink channel in the corresponding frequency block group in the cell with the smallest index among the multiple uplink channels.

[0221] As an example, the indexes in the second index set are all frequency block group indexes.

[0222] As an example, when an index set contains only one index, that index is the smallest index in the index set.

[0223] As an example, for a cell that includes only one frequency block group (since there is no need to distinguish between frequency block groups on the cell), the following two descriptions can be considered completely equivalent:

[0224] 1) An uplink channel is located on this frequency block group encompassed by this cell; and,

[0225] 2) There is an uplink channel in this cell.

[0226] As an example, the number of uplink channels in a cell among the plurality of uplink channels can be equal to 1 or greater than 1.

[0227] As an example, the number of uplink channels on the cell with the smallest index among the plurality of uplink channels can be equal to 1 or greater than 1.

[0228] As an example, the above method can support flexible uplink channel scheduling and has very good versatility.

[0229] As an example, the number of indexes in the second index set can be equal to 1 or greater than 1; when the second index set includes only one index (the number of indexes in the second index set is equal to 1), the frequency block group with the smallest index included in the cell with the smallest index is the frequency block group corresponding to the only index included.

[0230] As an example, for each of the plurality of uplink channels, all frequency domain resources allocated to that uplink channel are within a frequency block group included in a cell.

[0231] As an example, if there is an uplink channel among the multiple uplink channels whose frequency domain allocation is distributed across multiple frequency block groups in a cell, then the frequency block group to which this uplink channel is located can be defined as the frequency block group with the smallest index among the multiple frequency block groups, and the uplink channel used for reusing the first UCI can be determined based on this.

[0232] Example 7

[0233] Example 7 illustrates a schematic diagram of an uplink channel for multiplexing a first UCI according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown. In the appendix Figure 7 In the diagram, a box represents an uplink channel on the frequency block group with the smallest index that is included in the cell with the smallest index among the plurality of uplink channels.

[0234] In Embodiment 7, at least two of the plurality of uplink channels are on the frequency block group with the smallest index included in the cell with the smallest index, and the uplink channel used for multiplexing the first UCI is the earliest uplink channel among the at least two uplink channels.

[0235] As one embodiment, the at least two uplink channels are T uplink channels; without loss of generality, see Appendix Figure 7 Taking T equal to 2 as an example; the description in Example 7 also applies to the case where T is greater than 2.

[0236] As an example, the indices of cell #1, cell #2, and cell #3 are the same; the index of frequency block group #1 is greater than the index of frequency block group #2, and the index of frequency block group #3 is equal to the index of frequency block group #2 (in this case, frequency block group #2 and frequency block group #3 are the same frequency block group); the uplink channel used for multiplexing the first UCI is the earliest uplink channel between uplink channel #2 and uplink channel #3;

[0237] Among them, cell #1, cell #2, cell #3, frequency block group #1, frequency block group #2, frequency block group #3, uplink channel #2 and uplink channel #3 can be referred to in embodiment 6.

[0238] As an example, when the start time of one of the at least two uplink channels is not later than the start time of any of the other uplink channels in the at least two uplink channels, the one uplink channel in the at least two uplink channels is the earliest uplink channel in the at least two uplink channels.

[0239] As an example, within the same frequency block group included in the same cell, there are no two uplink channels belonging to the plurality of uplink channels with the same start time.

[0240] As an example, only one of the at least two uplink channels is the earliest uplink channel.

[0241] As an example, there is no time-domain overlap between any two of the at least two uplink channels.

[0242] As an example, one of the at least two uplink channels may overlap with another of the at least two uplink channels in the time domain.

[0243] As an example, if it is permissible for several uplink channels among the at least two uplink channels to be the earliest uplink channels (in which case the start times of the several uplink channels are the same, and the start time of each of the several uplink channels is no later than the start time of any other uplink channel among the at least two uplink channels), then the uplink channel used for multiplexing the first UCI can be an uplink channel determined from the several uplink channels according to a predefined selection rule.

[0244] As a sub-implementation of the above embodiments, generally speaking, for the predefined selection rules, as long as the communicating parties reach a consensus, it is acceptable; as a non-limiting implementation, an uplink channel with higher priority or an uplink channel with a smaller coresetPoolIndex can be selected.

[0245] As an example, the start time of an uplink channel is the time-domain start position of the time-domain resources allocated to that uplink channel.

[0246] As an example, see the attached document. Figure 7 As shown in the diagram (each box represents an uplink channel), the start time of an uplink channel is the time domain position of the left edge of the corresponding box.

[0247] As an example, the start time of an uplink channel can also be determined by symbol (in this case, the start time of an uplink channel is the earliest symbol assigned to that uplink channel).

[0248] As one example, one of the multiple uplink channels can be within a single frequency block (in which case the frequency domain resources allocated to this uplink channel are all within the same frequency block) or span multiple frequency blocks.

[0249] As an example, a time-domain configuration is configured for at least one frequency block.

[0250] As one example, one of the multiple uplink channels spans multiple frequency blocks, all of which correspond to the same time-domain configuration.

[0251] As an example, a given uplink channel is one of the plurality of uplink channels, the given uplink channel spans multiple frequency blocks, and the plurality of frequency blocks correspond to different time domain configurations; the time domain allocation of the given uplink channel is determined according to a reference time domain configuration, the reference time domain configuration being one of the different time domain configurations.

[0252] As an example, the reference time domain configuration refers to which of the different time domain configurations is determined according to predefined rules.

[0253] As an example, the reference time-domain configuration is the time-domain configuration corresponding to the frequency block with the smallest index among the multiple frequency blocks spanned by the given uplink channel among the different time-domain configurations.

[0254] As an example, the reference time-domain configuration is the time-domain configuration corresponding to the frequency block with the largest index among the multiple frequency blocks spanned by the given uplink channel among the different time-domain configurations.

[0255] As an example, the reference time-domain configuration is the time-domain configuration corresponding to the frequency block with the largest bandwidth among the multiple frequency blocks spanned by the given uplink channel among the different time-domain configurations.

[0256] As one embodiment, the given uplink channel spans multiple frequency blocks, including: each of the multiple frequency blocks includes a portion of frequency domain resources allocated to the given uplink channel.

[0257] As an example, different frequency blocks do not overlap in the frequency domain.

[0258] As an example, the multiple frequency blocks spanned by the given uplink channel belong to the same frequency block group.

[0259] As an example, a time-domain configuration is configured for each of the plurality of frequency blocks spanned by the given uplink channel.

[0260] As an example, a time-domain configuration is configured by RRC signaling.

[0261] As an example, a time-domain configuration includes the indication method for time-domain allocation (e.g., the granularity of time-domain resource indication, whether it is indicated by SLIV (Start and Length Indicator Value) or by directly indicating the start symbol and allocation length, etc.).

[0262] As an example, a time-domain configuration includes a configuration of multiple candidate time-domain assignments.

[0263] As an example, when an uplink channel is within a frequency block, the time domain allocation of this uplink channel is determined according to the time domain configuration corresponding to this frequency block.

[0264] As a sub-implementation of the above embodiment, the time-domain allocation of this uplink channel is indicated by the scheduling signaling of this uplink channel.

[0265] As one example, a time-domain configuration includes a configuration of multiple candidate time-domain assignments;

[0266] The time-domain allocation of the given uplink channel is indicated by the scheduling signaling of the given uplink channel, and the candidates for the time-domain allocation of the given uplink channel are configured by the reference time-domain configuration.

[0267] As an example, a candidate time-domain allocation includes at least the starting symbol and allocation length within the time slot.

[0268] As an example, a candidate time-domain allocation includes a time slot offset (relative to the time slot where the scheduling signaling is located), the starting symbol within the time slot, and the allocation length.

[0269] As an example, a symbol in this application (e.g., the earliest symbol or start symbol mentioned above) is a symbol defined in the time domain.

[0270] As an example, a symbol in this application (such as the earliest symbol or starting symbol mentioned above) is an OFDM (Orthogonal Frequency Division Multiplex) symbol.

[0271] As an example, a symbol in this application (e.g., the earliest symbol or start symbol mentioned above) is a symbol in a slot.

[0272] Example 8

[0273] Example 8 illustrates a schematic diagram showing the time-domain overlap between one of the multiple uplink channels according to an embodiment of this application and the first PUCCH, as shown in the attached diagram. Figure 8 As shown. In the appendix Figure 8 In the diagram, a gray-filled box represents one of the plurality of uplink channels, and a blank box represents the first PUCCH.

[0274] As an example, the first PUCCH is not transmitted.

[0275] As an example, the signaling received by the first node indicates that the first UCI is carried by the first PUCCH.

[0276] As a sub-implementation of the above embodiment, the second node sends the signaling.

[0277] As an example, the plurality of uplink channels overlap with the first PUCCH in the time domain.

[0278] As an example, the multiple uplink channels may overlap (completely or partially) or not overlap with each other in the time domain.

[0280] Example 9 illustrates a structural block diagram of a processing apparatus for a first node according to an embodiment of this application; as shown in the appendix. Figure 9 As shown.
