Description

Technical Field

[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] CSI (Channel State Information) reporting is a key technology in mobile communications; the network side can use the reported CSI to set appropriate transmission parameters for scheduled transmissions to improve transmission performance. Summary of the Invention

It should be noted that while this application is primarily motivated by scenarios supporting multiple carriers within the same cell (different frequency blocks can be on different carriers), it 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.

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.).

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0187] Example 5

[0188] 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.

[0189] The first node U1 receives the first signaling in step S510 and sends the first CSI report in step S511.

[0190] The second node U2 sends the first signaling in step S520 and receives the first CSI report in step S521.

[0191] In Example 5, the priority value of the first CSI report depends on the first cell index and has a linear relationship with the first frequency block group index; the cell corresponding to the first cell index includes multiple frequency block groups, and a frequency block group includes at least one frequency block included in the cell to which it belongs; the frequency block group corresponding to the first frequency block group index is one of the multiple frequency block groups included in the cell corresponding to the first cell index.

[0192] The priority value of the first CSI report has a linear relationship with the ID configured for the first CSI report;

[0193] The first signaling instruction is to send the first CSI report on the uplink channel; the first cell index is the index of the cell that configures the configuration parameters of the first CSI report, and the transmission of the first CSI report depends on the frequency block group corresponding to the first frequency block group index.

[0194] As a sub-example of Example 5, the priority value of the first CSI report is equal to the sum of multiple components; the multiple components include at least a first component and a second component, the first component being equal to a positive integer multiple of the first frequency block group index, and the second component being equal to a positive integer multiple of the first cell index.

[0195] As a sub-implementation of Embodiment 5, the first frequency block group index is an index determined by sorting all frequency block groups included in multiple cells, wherein the multiple cells include the cell corresponding to the first cell index; the determination of the first frequency block group index depends on the first cell index.

[0196] As a sub-implementation of Embodiment 5, the priority value of the first CSI report is equal to the sum of multiple components; the multiple components include at least a first component and a second component, the first component is equal to a positive integer multiple of the first frequency block group index, and the second component is equal to a positive integer multiple of the first cell index; the cell corresponding to the first cell index includes multiple frequency blocks, and the different frequency blocks included in the cell corresponding to the first cell index are on different carriers; the smaller the priority value of the CSI report, the higher the priority.

[0197] As a sub-implementation of Embodiment 5, the first frequency block group index is an index determined by sorting all frequency block groups included in multiple cells, wherein the multiple cells include the cell corresponding to the first cell index; the determination of the first frequency block group index depends on the first cell index; the cell corresponding to the first cell index includes multiple frequency blocks, and the different frequency blocks included in the cell corresponding to the first cell index are on different carriers; the smaller the priority value of the CSI report, the higher the priority.

[0198] As an example, the first node U1 is the first node in this application.

[0199] As an example, the second node U2 is the second node in this application.

[0200] As an example, the first node U1 is a UE.

[0201] As one example, the second node U2 is a base station.

[0202] As one embodiment, the air interface between the second node U2 and the first node U1 is the Uu interface.

[0203] As one embodiment, the air interface between the second node U2 and the first node U1 includes a cellular link.

[0204] 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.

[0205] 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.

[0206] 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.

[0207] As an example, the steps in the dashed box F1 are present.

[0208] As an example, the step in the dashed box F1 does not exist.

[0209] As an example, when multiple CSI reports need to be reported through a given transmission resource but the given transmission resource is insufficient to carry all the contents of the multiple CSI reports, the first node prioritizes sending the CSI report with higher priority among the multiple CSI reports.

[0210] As an example, a CSI report may include a first part CSI (CSI part 1) and a second part CSI (CSI part 2).

[0211] As an example, if there are Q CSI reports that need to be reported using a given transmission resource, but the given transmission resource is insufficient to carry all the contents of the Q CSI reports, the first node needs to abandon the transmission of the second part of the CSI in some of the CSI reports;

[0212] According to the following description of the levels, starting from level 2Q (in reverse order), the corresponding parts are skipped level by level (the skipped parts are not sent) until the given transmission resources are sufficient to carry the remaining unskipped parts of the Q CSI reports;

[0213] Level 1: Even-numbered portions of subband CSIs in Part 2 of CSI report #1;

[0214] Level 2: The odd-numbered portion of the subband CSI in Part 2 of CSI report #1;

[0215] Level 3: Even-numbered portions of subband CSI within Part 2 of CSI report #2;

[0216] Level 4: Odd-numbered portions of subband CSIs in Part 2 of CSI report #2; ...

[0218] Level 2Q-1: The even-numbered portion of the CSI subband in the second part of the CSI report #Q;

[0219] Level 2Q: The odd-numbered portion of the subband CSI in the second part of the CSI report #Q;

[0220] Among them, CSI report #t has a higher priority than CSI report #t+1 (where t can be any value from 1 to Q-1).

[0221] Without loss of generality, the above example assumes that each of the Q CSI reports includes the second part of the CSI. However, there may also be CSI reports that do not include the second part of the CSI. In such cases, the corresponding level in the above description can be removed and a similar step-by-step skipping method can be adopted.

[0222] As one example, the given transmission resources include allocated time-frequency resources.

[0223] As an example, the given transmission resource may be a PUSCH.

[0224] As an example, the given transport resource is also used for the transport of transport blocks.

[0225] As an example, if the multiplication of the number of REs included in the given transmission resource, the configured modulation order, and the configured code rate is not less than the total number of bits of the target information and the corresponding CRC (if a CRC exists), then the given transmission resource is considered sufficient to carry the target information; otherwise, the given transmission resource is considered insufficient to carry the target information.

[0226] The above description applies to the following two situations:

[0227] 1) The target information is the Q CSI reports; and,

[0228] 2) The target information is the remaining, un-omitted portion of the Q CSI reports.

[0229] As one example, the given transmission resource is PUSCH; when Less than or equal to If the given transmission resources are sufficient to carry the target information, then the given transmission resources are considered sufficient to carry the target information; otherwise, the given transmission resources are considered insufficient to carry the target information.

[0230] Wherein, the L CSI-2 This refers to the number of CRC (Cyclic Redundancy Check) bits in the second part of the CSI. (Indicated by the beta_offset indicator field in the scheduling signaling of the given transmission resource), the Q' CSI-1 Q′ is the number of coded modulation symbols per layer of the first part of CSI transmitted in the given transmission resources. ACK / CG-UCI =0, the C UL-SCHK is the number of codeblocks transmitted via the given transmission resources in the UL-SCH (Uplink Shared Channel). r The size of the r-th code block of the UL-SCH transmitted through the given transmission resources is the size of the r-th code block. This refers to the number of REs that can be used to transmit UCI (Uplink Control Information) in OFDM (Orthogonal Frequency Division Multiplexing) symbol 1. It is the total number of OFDM symbols in the given transport resource (including all OFDM symbols used for DM-RS), where α is a parameter configuration;

[0231] The above description applies to the following two situations:

[0232] 3) The O CSI-2 The target information is the total number of bits of all the second-part CSIs included in the Q CSI reports; and,

[0233] 4) The O CSI-2 It is the total number of bits belonging to the second part of CSI in the remaining, unskipped portions of the Q CSI reports, and the target information is the remaining, unskipped portions of the Q CSI reports.

[0234] As an example, the communicating parties need to reach a consensus on how to determine the priority value of the CSI report.

[0235] As an example, the first signaling is physical layer signaling.

[0236] As an example, the first signaling is DCI (Downlink Control Information).

[0237] As an example, the first signaling includes at least one field in the DCI format.

[0238] As an example, the first signaling is higher-layer signaling.

[0239] As an example, the first signaling explicitly instructs the transmission of the first CSI report on the first channel.

[0240] As an example, the first signaling implicitly indicates that the first CSI report is sent on the first channel.

[0241] As an example, the first channel is a physical uplink channel.

[0242] As an example, the first channel is PUSCH.

[0243] As an example, the first channel is PUCCH.

[0244] As an example, the first signaling is transmitted on the frequency block group corresponding to the first frequency block group index.

[0245] As one embodiment, the frequency domain resources used to transmit the first signaling are a subset of the frequency domain resources included in the frequency block group corresponding to the first frequency block group index.

[0246] Example 6

[0247] Example 6 illustrates a schematic diagram of the priority value of a first CSI report according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown.

[0251] As an example, the first frequency block group index is configured to a frequency block group included in the cell corresponding to the first cell index, and the frequency block group included in the cell corresponding to the first cell index is the frequency block group corresponding to the first frequency block group index.

[0252] As an example, the first frequency block group index is an index determined by sorting all frequency block groups included in the cell corresponding to the first cell index according to a predefined sorting rule.

[0253] As a sub-implementation of the above embodiments, the predefined sorting rule may be: according to the frequency block group's starting position in the frequency domain, from low to high, the frequency block group index increases sequentially; or...

[0254] The predefined sorting rule could be: frequency block group indices decreasing sequentially from low to high frequency domain starting positions; or...

[0255] The predefined sorting rule can also be other sorting rules agreed upon in advance by the two communicating parties.

[0258] As an example, p3 is the product of multiple factors (each of the multiple factors corresponding to p3 is either a constant greater than 0 or a value indicated by a parameter).

[0259] As an example, p3 is equal to W multiplied by N. cell Multiply by N CCG Multiply by M s .

[0260] As an example, W is 2.

[0261] As an example, W is equal to the number of candidates for k.

[0262] As an example, the N cell It is predefined or configured, the N cell This equals the maximum number of service cells.

[0269] As an example, a configuration for a CSI report includes at least a portion of the Information Element (IE) CSI-ReportConfig.

[0270] As an example, each candidate value of y depends on at least one of the time-domain characteristics of the CSI report and the type of the physical channel carrying the CSI report.

[0271] As an example, y is determined based on at least one of the time-domain characteristics of the first CSI report and the type of the physical channel carrying the first CSI report.

[0272] As an example, the candidate values ​​for y include values ​​representing CSI reports carried by PUSCH and values ​​representing CSI reports carried by PUCCH.

[0273] As an example, the candidate values ​​for y include values ​​representing aperiodic CSI reports, values ​​representing semi-persistent CSI reports, and values ​​representing periodic CSI reports.

[0274] As an example, the candidate values ​​of y include at least one of the following values:

[0275] This represents the aperiodic CSI report value for the PUSCH bearer, the semi-persistent CSI report value for the PUSCH bearer, the semi-persistent CSI report value for the PUCCH bearer, and the periodic CSI report value for the PUCCH bearer.

[0276] As an example, for aperiodic CSI reports of PUSCH bearers, y = 0; for semi-persistent CSI reports of PUSCH bearers, y = 1; for semi-persistent CSI reports of PUCCH bearers, y = 2; and for periodic CSI reports of PUCCH bearers, y = 3.

[0280] As an example, p2 equals N cell Multiply by N CCG Multiply by M s .

[0281] As an example, each candidate value of k depends on the content of the CSI report.

[0282] As an example, k is determined based on the content of the first CSI report.

[0283] As an example, for CSI reports carrying the RSRP (L1-RSRP) or SINR (L1-SINR) of layer 1, k = 0; for CSI reports not carrying L1-RSRP or L1-SINR, k = 1.

[0284] As an example, for a CSI report carrying L1-RSRP or L1-SINR, k = 0; for a CSI report carrying CQI but not L1-RSRP and L1-SINR, k = 1; for a CSI report carrying neither L1-RSRP, L1-SINR, nor CQI, k = 2.

[0294] Example 7

[0295] Example 7 illustrates a schematic diagram of the priority value of a first CSI report according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown.

[0296] In Example 7, the priority value of the first CSI report is equal to p5 multiplied by y plus p4 multiplied by k plus p0 multiplied by the first frequency block group index plus s.

[0297] In Embodiment 7, the first frequency block group index is an index determined by sorting all frequency block groups included in multiple cells, and the multiple cells include the cell corresponding to the first cell index; the determination of the first frequency block group index depends on the first cell index.

[0298] As an example, the sorting rules for sorting all frequency block groups included in the multiple cells can be as follows: first, in ascending order of the index of the frequency block group within the same cell (each frequency block can be configured with an index within its own cell); second, in ascending order of the index of its own cell.

[0299] As a sub-example of the above embodiments, the sorting rule is illustrated below:

[0300] The plurality of cells include the cells corresponding to the first cell index and the cells corresponding to the second cell index, wherein the first cell index is greater than the second cell index; the cells corresponding to the first cell index include frequency block group #0 and frequency block group #1, wherein the intra-cell index of frequency block group #0 is less than the intra-cell index of frequency block group #1; the cells corresponding to the second cell index include frequency block group #2 and frequency block group #3, wherein the intra-cell index of frequency block group #2 is greater than the intra-cell index of frequency block group #3;

[0301] Four indices (e.g., 0, 1, 2, 3) correspond in ascending order to frequency block group #3, frequency block group #2, frequency block group #0, and frequency block group #1 (wherein, the frequency block group corresponding to the first frequency block group index is frequency block group #0, and the first frequency block group index is 2; or, the frequency block group corresponding to the first frequency block group index is frequency block group #1, and the first frequency block group index is 3).

[0302] As a sub-example of the above embodiments, the sorting rule is illustrated below:

[0303] The plurality of cells includes the cell corresponding to the first cell index, the cell corresponding to the second cell index, and the cell corresponding to the third cell index; the first cell index is greater than the second cell index, and the first cell index is less than the third cell index; the cell corresponding to the first cell index includes frequency block group #0 and frequency block group #1, and the intra-cell index of frequency block group #1 is less than the intra-cell index of frequency block group #0; the cell corresponding to the second cell index includes frequency block group #2 (this is a case that needs special explanation; in this case, the cell corresponding to the second cell index includes only one frequency block group; for the cell corresponding to the second cell index, there is no ordering between frequency block groups within the cell); the cell corresponding to the third cell index includes frequency block group #3, frequency block group #4, and frequency block group #5, and the intra-cell index of frequency block group #3 is less than the intra-cell index of frequency block group #4, and the intra-cell index of frequency block group #4 is less than the intra-cell index of frequency block group #5;

[0304] The six indices (e.g., 0, 1, 2, 3, 4, 5) correspond in ascending order to the frequency block group #2, the frequency block group #1, the frequency block group #0, the frequency block group #3, the frequency block group #4, and the frequency block group #5 (wherein, the frequency block group corresponding to the first frequency block group index is the frequency block group #0, and the first frequency block group index is 2; or, the frequency block group corresponding to the first frequency block group index is the frequency block group #1, and the first frequency block group index is 1).

[0305] As an example, the sorting rules for sorting all frequency block groups included in the multiple cells can be as follows: first, in descending order of the index of the frequency block group within the same cell (each frequency block can be configured with an index within its own cell); second, in descending order of the index of its own cell.

[0306] As a sub-example of the above embodiments, the sorting rule is illustrated below:

[0307] The plurality of cells includes the cell corresponding to the first cell index, the cell corresponding to the second cell index, and the cell corresponding to the third cell index; the third cell index is greater than the second cell index and less than the first cell index; the cell corresponding to the third cell index includes frequency block group #0 and frequency block group #1, and the intra-cell index of frequency block group #1 is less than the intra-cell index of frequency block group #0; the cell corresponding to the second cell index includes frequency block group #2; the cell corresponding to the first cell index includes frequency block group #3, frequency block group #4, and frequency block group #5, and the intra-cell index of frequency block group #3 is less than the intra-cell index of frequency block group #4, and the intra-cell index of frequency block group #4 is less than the intra-cell index of frequency block group #5;

[0308] The six indices (e.g., 0, 1, 2, 3, 4, 5) correspond in ascending order to the frequency block group #5, the frequency block group #4, the frequency block group #3, the frequency block group #0, the frequency block group #1, and the frequency block group #2 (where the frequency block group corresponding to the first frequency block group index is the frequency block group #3 and the first frequency block group index is 2; or, the frequency block group corresponding to the first frequency block group index is the frequency block group #4 and the first frequency block group index is 1; or, the frequency block group corresponding to the first frequency block group index is the frequency block group #5 and the first frequency block group index is 0).

[0309] As an example, the sorting rule followed when sorting all frequency block groups included in the plurality of cells can also be:

[0310] First, sort by the index of the frequency block group within the same cell in ascending order (each frequency block can be configured with an index within its own cell); second, sort by the index of the cell to which it belongs in descending order.

[0311] Alternatively, it could be:

[0312] First, sort by the index of the frequency block group within the same cell in descending order (each frequency block can be configured with an index within its own cell); second, sort by the index of the cell to which it belongs in ascending order.

[0313] As an example, p5 is configurable.

[0314] As an example, p5 is determined based on higher-level parameters.

[0315] As an example, p5 is the product of multiple factors (each of the multiple factors corresponding to p5 is either a constant greater than 0 or a value indicated by a parameter).

[0316] As an example, p5 is equal to W multiplied by N. totalCCG Multiply by M s .

[0317] As an example, W is 2.

[0318] As an example, W is equal to the number of candidates for k.

[0319] As an example, the N totalCCG It is predefined or configured, the N cell It equals the maximum number of all frequency block groups included in all cells.

[0320] As an example, the N totalCCG It is predefined or configured, the N cell It equals the maximum number of all frequency blocks included in all cells.

[0321] As an example, the N totalCCG equals N cell Multiply by N CCG .

[0322] As an example, the N cell It is predefined or configured, the N cell This equals the maximum number of service cells.

[0323] As an example, the N CCG It is predefined or configured, the N CCG It equals the maximum number of frequency block groups included in a cell.

[0327] As an example, a configuration for a CSI report includes measurement configuration and corresponding reporting method.

[0328] As an example, a configuration for a CSI report includes: the number of measurements to be reported (e.g., how many measurement items need to be reported), the measurement object (e.g., the physical resources for downlink measurements), and the actual reporting method (e.g., which physical uplink channel carries the reporting).

[0329] As an example, a configuration for a CSI report includes at least a portion of the information element CSI-ReportConfig.

[0330] As an example, each candidate value of y depends on at least one of the time-domain characteristics of the CSI report and the type of the physical channel carrying the CSI report.

[0331] As an example, y is determined based on at least one of the time-domain characteristics of the first CSI report and the type of the physical channel carrying the first CSI report.

[0332] As an example, the candidate values ​​for y include values ​​representing CSI reports carried by PUSCH and values ​​representing CSI reports carried by PUCCH.

[0333] As an example, the candidate values ​​for y include values ​​representing aperiodic CSI reports, values ​​representing semi-persistent CSI reports, and values ​​representing periodic CSI reports.

[0334] As an example, the candidate values ​​of y include at least one of the following values:

[0335] This represents the aperiodic CSI report value for the PUSCH bearer, the semi-persistent CSI report value for the PUSCH bearer, the semi-persistent CSI report value for the PUCCH bearer, and the periodic CSI report value for the PUCCH bearer.

[0336] As an example, for aperiodic CSI reports of PUSCH bearers, y = 0; for semi-persistent CSI reports of PUSCH bearers, y = 1; for semi-persistent CSI reports of PUCCH bearers, y = 2; and for periodic CSI reports of PUCCH bearers, y = 3.

[0337] As an example, p4 is configurable.

[0338] As an example, p4 is determined based on higher-level parameters.

[0339] As an example, p4 is the product of multiple factors (each of the multiple factors corresponding to p4 is either a constant greater than 0 or a value indicated by a parameter).

[0340] As an example, p4 equals N totalCCG Multiply by M s .

[0341] As an example, each candidate value of k depends on the content of the CSI report.

[0342] As an example, k is determined based on the content of the first CSI report.

[0343] As an example, for CSI reports carrying the RSRP (L1-RSRP) or SINR (L1-SINR) of layer 1, k = 0; for CSI reports not carrying L1-RSRP or L1-SINR, k = 1.

[0344] As an example, for a CSI report carrying L1-RSRP or L1-SINR, k = 0; for a CSI report carrying CQI but not L1-RSRP and L1-SINR, k = 1; for a CSI report carrying neither L1-RSRP, L1-SINR, nor CQI, k = 2.

[0345] As an example, p0 is configurable.

[0346] As an example, p0 is determined based on higher-level parameters.

[0350] Example 8

[0351] Example 8 illustrates a schematic diagram of CSI reporting according to an embodiment of this application, as shown in the attached diagram. Figure 8 As shown.

[0352] In Example 8, J (where J is a positive integer, which can be equal to or greater than 1) transmission resources are allocated to the first node. These J transmission resources are indexed in ascending order (from 0 to J-1) based on the product of the configured number of Resource Elements (REs), the modulation order, and the configured code rate. The first node uses one of these J transmission resources to transmit at least a portion of multiple CSI reports in the following manner:

[0353] When O CSI +O CRC ≤M RE,0 ×Q m,0 When ×r00, the first node uses transmission resource 0 to send the plurality of CSI reports;

[0354] When O CSI +O CRC >M RE,i ×Q m,i ×r0 i And O CSI +O CRC ≤M RE,i+1 ×Q m,i+1 ×r0 i+1 At that time, the first node uses transmission resource i+1 to send the plurality of CSI reports; (0≤i≤J-1; when J equals 1, this branch does not exist)

[0355] When O CSI +O CRC >M RE,J-1 ×Q m,J-1 ×r0 J-1 At that time, the first node uses transmission resource J-1 to send the X highest priority CSI reports from the plurality of CSI reports (where X satisfies: the sum of the total number of bits included in the X highest priority CSI reports and the total number of corresponding CRC bits does not exceed M). RE,J-1 ×Q m,J-1 ×r0 J-1 Furthermore, the sum of the total number of bits included in the X+1 highest priority CSI reports and the total number of corresponding CRC bits exceeds M. RE,J-1 ×Q m,J-1 ×r0 J-1 );

[0356] Wherein, the O CSI This indicates the total number of bits included in the plurality of CSI reports, the O CRC M represents the total number of CRC bits for the multiple CSI reports. RE,iQ is equal to the number of REs available for transmitting CSI in transmission resource i. m,i The r0 represents the modulation order configured for transmission resource i. i This represents the bitrate configured for transmission resource i.

[0357] As an example, a CSI report includes a first part CSI and a second part CSI; the number of bits included in the CSI report is equal to the sum of the number of bits in the first part CSI and the number of bits in the second part CSI included in the CSI report, and the CRC bits for the CSI report include: CRC bits added to the first part CSI included in the CSI report (if added) and CRC bits added to the second part CSI included in the CSI report (if added).

[0358] As an example, a CSI report may not be split into multiple parts (a first part of CSI and a second part of CSI), or it may only include a first part of CSI.

[0359] As an example, a transport resource is configured for transporting UCI.

[0360] As an example, a transport resource is a PUCCH resource.

[0361] As an example, the number of REs available for transmitting CSI in a transport resource is configurable.

[0362] As an example, the number of REs available for transmitting CSI in transmission resource i is equal to M. RB,i ×N sc,i ×N symb,i ; wherein, the M RB,i N is the number of RBs configured for the transmission resource i. sc,i The number of subcarriers in each RB of the transmission resource i, excluding the subcarriers used for transmitting the DM-RS (Demodulation Reference Signal), is equal to the number of subcarriers in N. symb,i It is equal to the number of OFDM symbols allocated to the transmission resource i, excluding the OFDM symbols used for DM-RS transmission.

[0363] As an example, the multiple CSI reports overlap in the time domain.
