[0245] Example 3

[0246] 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.).

[0260] Example 4

[0261] 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 the access network.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] 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.

[0267] 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.

[0323] As one embodiment, all frequency domain resources in all frequency blocks included in the first frequency block set are divided into multiple nominal frequency bands according to predefined rules, and the multiple nominal frequency bands constitute the nominal frequency band set.

[0324] As an example, all frequency domain resources in all frequency blocks included in the first frequency block set are randomly divided into multiple nominal frequency bands, and the multiple nominal frequency bands constitute the nominal frequency band set.

[0325] As an example, the union of all frequency domain resources in all frequency blocks included in the first frequency block set and a given frequency domain resource is divided into multiple nominal frequency bands according to a predefined rule, and the multiple nominal frequency bands constitute the nominal frequency band set.

[0326] As an example, the union of all frequency domain resources in all frequency blocks included in the first frequency block set and a given frequency domain resource is randomly divided into multiple nominal frequency bands, and the multiple nominal frequency bands constitute the nominal frequency band set.

[0327] As one embodiment, the given frequency domain resources include frequency domain resources that do not belong to any frequency block included in the first set of frequency blocks.

[0328] As one example, the given frequency domain resources are configured by higher-level signaling.

[0331] As one embodiment, the second node sends a physical channel, and the first node receives the physical channel; the frequency domain resources occupied by the transmission of the physical channel span multiple frequency blocks in the first frequency block set.

[0332] It should be noted that receiving (or transmitting) the first physical channel is a common expression in the art, meaning receiving (or transmitting) on ​​the first physical channel, or meaning receiving (or transmitting) a signal (e.g., modulation symbol) on the first physical channel; the above expression is beneficial for maintaining consistency with the general expression in the art.

[0333] As one embodiment, the CSI reporting includes: sending a CSI report; the CSI receiving includes: receiving the CSI report.

[0343] Example 6 illustrates a schematic diagram of a set of multiple frequency blocks according to an embodiment of the present application, where a set of frequency blocks includes frequency blocks on multiple carriers in a set of carriers, as shown in the attached diagram. Figure 6 As shown.

[0344] In embodiment 6, one of the multiple frequency block sets includes frequency blocks on carrier #g; wherein g is any value from 1, 2, ..., M.

[0345] As an example, carrier #1, carrier #2, ..., carrier #M are different carriers in the carrier set.

[0346] As an example, M is less than the number of carriers included in the carrier set, or M is equal to the number of carriers included in the carrier set.

[0347] As an example, M is a positive integer greater than 1.

[0348] As an example, M is configurable.

[0349] As an example, M is a higher-layer signaling configuration.

[0350] As an example, the introduction of "#number" in this application is to distinguish different carriers, or different sets of frequency blocks, or different frequency blocks, or different nominal frequency bands; "#number" is not necessarily an actual index.

[0351] As an example, the following situation is allowed:

[0352] A frequency block on one carrier belongs to one set of frequency blocks in the plurality of frequency block sets, but does not belong to another set of frequency blocks in the plurality of frequency block sets; a frequency block on another carrier belongs to the other set of frequency blocks in the plurality of frequency block sets, but does not belong to the first set of frequency blocks in the plurality of frequency block sets.

[0353] As an example, the number of frequency blocks included in different frequency block sets among the plurality of frequency block sets may be the same or different.

[0354] As an example, the advantages of the above method include: high configuration flexibility.

[0355] As an example, each of the plurality of frequency block sets includes a frequency block on a first carrier; for each of the plurality of frequency block sets, the candidates for the frequency block on the first carrier included include different frequency blocks on the first carrier.

[0356] As an example, the advantages of the above method include: providing the possibility of flexibly utilizing different frequency blocks on the same carrier, which is conducive to improving the utilization efficiency of the carrier's frequency domain resources and saving energy.

[0357] As an example, the advantages of the above method include: providing the possibility of using the first carrier as the anchor carrier of the same cell (regardless of which frequency block in the plurality of frequency block sets is enabled, there will always be a usable frequency block on the first carrier), which helps to simplify system design, reduce UE costs, and improve commercial value.

[0358] As an example, the advantages of the above method include: balancing energy savings and simplified system design, which is very beneficial for reducing UE costs.

[0368] As an example, Q is a higher-layer signaling configuration.

[0369] Example 8

[0370] Example 8 illustrates a schematic diagram of the first signaling according to an embodiment of this application, as shown in the attached diagram. Figure 8 As shown.

[0371] In Embodiment 8, the first node receives a first signaling; the first signaling instructs the activation of all frequency blocks included in the first frequency block set.

[0372] As an example, based on the indication of the first signaling, all frequency blocks included in the first frequency block set are activated together.

[0373] As an example, being enabled in this application includes being activated.

[0374] As an example, being enabled in this application includes being activated.

[0375] As an example, the "closed" statement in this application includes: being disabled.

[0376] As an example, being turned off in this application includes being deactivated.

[0377] As an example, when a frequency block in the first frequency block set is in an open state, all frequency blocks in the plurality of frequency block sets that do not belong to the first frequency block set are in a closed state.

[0378] As an example, the first signaling explicitly instructs the activation of all frequency blocks included in the first frequency block set.

[0379] As an example, the first signaling implicitly indicates that all frequency blocks included in the first frequency block set are enabled.

[0380] As an example, the first signaling is physical layer signaling.

[0381] As an example, the first signaling is transmitted on the PDCCH (Physical Downlink Control Channel).

[0382] As an example, the first signaling is DCI (Downlink Control Information).

[0383] As an example, the first signaling is in DCI format.

[0388] As an example, the advantages of the above method include: high reliability of signaling transmission.

[0389] Example 9

[0390] Example 9 illustrates a flowchart of communication of a first node according to an embodiment of this application, as shown in the attached diagram. Figure 9 As shown.

[0391] The first node 900 receives the first information block in step 901 and reports the CSI in step 902.

[0392] In Example 9, the first information block indicates at least one carrier in a carrier set, all of which belong to the same cell; the first frequency block set includes frequency blocks on multiple carriers in the carrier set; the nominal frequency band set includes multiple nominal frequency bands, each of which is reported for CSI; the nominal frequency band set depends on the first frequency block set; the first nominal frequency band is one of the nominal frequency bands in the nominal frequency band set, and the first nominal frequency band includes at least one actual sub-band; the number of actual sub-bands included in the first nominal frequency band depends on the distribution of the first nominal frequency band in the first frequency block set; each actual sub-band included in the first nominal frequency band is a sub-band reported by CSI.

[0393] As a sub-implementation of the above embodiment, the second node sends the first information block and receives CSI.

[0394] Example 10

[0395] Example 10 illustrates a schematic diagram of the relationship between the nominal frequency band set and the first frequency block set according to an embodiment of this application, as shown in the attached diagram. Figure 10 As shown. In the appendix Figure 10 In the first set of frequency blocks, there are F frequency blocks (frequency block #0, frequency block #1, and frequency block #2), where F = 3; in the appendix Figure 10 In (1), each box represents a frequency domain unit, a gray-filled box represents a frequency domain unit in frequency block #0, a blank box represents a frequency domain unit in frequency block #1, and a diagonally filled box represents a frequency domain unit in frequency block #2.

[0396] In Example 10, the nominal frequency band set includes T nominal frequency bands (nominal frequency band #s, s = 0, 1, ..., t1, ..., t2, ..., T-1), and each nominal frequency band included in the nominal frequency band set is for CSI reporting.

[0397] It should be noted that the appendix Figure 10 (1) does not indicate the actual frequency domain positions of frequency block #0, frequency block #1, and frequency block #2; frequency block #0, frequency block #1, and frequency block #2 may belong to the same frequency band or different frequency bands; Appendix Figure 10 (2) gives an example of the frequency domain allocation of the frequency block #0, the frequency block #1, and the frequency block #2.

[0398] Without loss of generality, Example 10 is illustrated with F = 3; however, F can also be any other integer greater than 1.

[0399] Furthermore, the nominal frequency band set may also be a different case from that described in Embodiment 10; in this other case, the nominal frequency band set only includes a portion of the T nominal frequency bands; and the nominal frequency band set includes which of the T nominal frequency bands are configurable.

[0400] As an example, F is configurable.

[0401] As an example, K is determined based on the configuration.

[0402] As an example, K is equal to the frequency block #0, and the frequency domain units included in the frequency block #1 and the frequency block #2 are always equal.

[0403] As an example, when a frequency domain unit is a frequency domain unit in a frequency block included in the first frequency block set, the frequency domain unit is a frequency domain unit in the first frequency block set.

[0404] As an example, a frequency domain unit is not a frequency domain unit in the first frequency block set when it is not a frequency domain unit in any frequency block included in the first frequency block set.

[0405] As an example, for a frequency domain cell u (where u = 0, 1, ..., K-1), u is the sorting index of the frequency domain cell u among all frequency domain cells in the first frequency block set.

[0406] As a sub-implementation of the above embodiments, the indices of the frequency domain units in the first frequency block set are sequentially increased according to the first order.

[0407] In addition to the above interpretation of u, u can also be interpreted in another way: u is used to distinguish different frequency domain units but is not a sorting index; when the interpretation of u as not a sorting index is adopted, the frequency domain units can be indexed within each frequency block (for the interpretation of u as not a sorting index, the frequency domain units do not need to be indexed across frequency blocks).

[0408] As an example, within a frequency block, the indices of the frequency domain units are sequentially increased in a first order.

[0409] As an example, in all frequency domain units included in the first frequency block set, frequency domain unit u+1 is the next frequency domain unit of frequency domain unit u (where u = 0, 1, ..., K-2) in a first order.

[0410] As a sub-implementation of the above embodiments, it should be noted that when the scope of consideration is not limited to the frequency domain units included in the first frequency block set, there may be other frequency domain resources between the frequency domain unit u+1 and the frequency domain unit u.

[0411] As an example, the first order described above is: the order of frequency domain positions from low to high.

[0412] As an example, the first order described above is: the order of frequency domain positions from high to low.

[0413] As an example, the meaning of a frequency domain unit can be predefined.

[0414] As an example, a frequency domain unit includes contiguous frequency domain resources.

[0415] As an example, a frequency domain unit includes at least one subcarrier.

[0416] As an example, a frequency domain unit is an RB.

[0417] As an example, a frequency domain unit is a PRB (Physical Resource Block).

[0418] As an example, a frequency domain unit is a CRB (Common Resource Block).

[0419] As an example, a frequency domain unit in a frequency block belongs to the frequency domain resources in that frequency block.

[0420] As an example, one frequency block in the first set of frequency blocks includes frequency domain units that are consecutive in the frequency domain.

[0421] As an example, the frequency domain units included in one frequency block of the first frequency block set are configurable.

[0422] As an example, the F (F=3) frequency blocks included in the first frequency block set can be defined as frequency block #0, frequency block #1 and frequency block #2 respectively according to a predefined rule.

[0423] As one embodiment, the frequency domain positions of frequency block #0, frequency block #1, and frequency block #2 increase sequentially (as shown in the attached diagram). Figure 10 shown in (2)).

[0424] As a sub-implementation of the above embodiments, the first order is: the frequency domain position from low to high.

[0425] As an example, the frequency domain positions of frequency block #0, frequency block #1 and frequency block #2 may also be progressively lower.

[0426] As a sub-implementation of the above embodiments, the first order is: the order of frequency domain positions from high to low.

[0427] As an example, the nominal frequency band set is configured.

[0428] As an example, the nominal frequency band set includes only one nominal frequency band.

[0429] As one example, the nominal frequency band set includes multiple nominal frequency bands.

[0430] As an example, a nominal frequency band includes contiguous frequency domain resources.

[0431] As an example, a nominal frequency band includes at least one frequency domain unit.

[0432] As an example, each nominal frequency band in the nominal frequency band set includes at least one frequency domain unit in the first frequency block set.

[0433] As an example, the frequency domain units included in any two nominal frequency bands in the nominal frequency band set do not overlap.

[0434] As an example, among all frequency domain units included in the first frequency block set, the first frequency domain unit in the nominal frequency band #(r+1) is the next frequency domain unit after the last frequency domain unit in the nominal frequency band #r (where r = 0, 1, ..., T-2) (e.g., appended). Figure 10In the nominal frequency band #0, the last frequency domain unit is frequency domain unit 1, the first frequency domain unit of nominal frequency band #1 is frequency domain unit 2, and so on.

[0435] As an example, T is determined according to the configuration.

[0436] As one embodiment, the nominal frequency band set depends on the first frequency block set, including: the size of at least one nominal frequency band in the nominal frequency band set depends on the first frequency block set.

[0437] As one embodiment, the nominal frequency band set depends on the first frequency block set, including: the size of at least one nominal frequency band in the nominal frequency band set depends on the total number of frequency domain units in the first frequency block set.

[0438] As an example, the size of a nominal frequency band in the nominal frequency band set is N1 - (N2 mod N1).

[0439] As an example, when (N2+N3)modN1 is not equal to 0, the size of a nominal frequency band in the nominal frequency band set is (N2+N3)modN1; when (N2+N3)modN1 is equal to 0, the size of the nominal frequency band in the nominal frequency band set is N1.

[0440] As an example, the size of the first nominal frequency band in the nominal frequency band set is N1 - (N2 mod N1).

[0441] As an example, when (N2+N3)modN1 is not equal to 0, the size of the last nominal frequency band in the nominal frequency band set is (N2+N3)modN1; when (N2+N3)modN1 is equal to 0, the size of the last nominal frequency band in the nominal frequency band set is N1.

[0442] As an example, the size of the nominal frequency bands in the nominal frequency band set, excluding the first and last nominal frequency bands, is N1.

[0443] As an example, in the appendix Figure 10 In (1), nominal frequency band #0 is the first nominal frequency band in the set of nominal frequency bands, and nominal frequency band #(T-1) is the last nominal frequency band in the set of nominal frequency bands.

[0444] As an example, the size refers to the number of frequency domain units included.

[0445] As an example, N1 is configurable.

[0446] As an example, N1 is greater than 1.

[0447] As an example, N2 is 0.

[0448] As a sub-implementation of the above embodiments, different from the appendix Figure 10 The size of the nominal frequency band #0 shown in (1) is equal to that of N1.

[0449] As an example, N2 is configurable.

[0450] As an example, N2 is an index of the starting position of the first frequency block set relative to a reference position.

[0451] As an example, N2 is equal to the number of frequency domain units offset from the starting position of the first frequency block set relative to a reference position.

[0452] As an example, the reference position is predefined.

[0453] As an example, the reference location is configurable.

[0454] As an example, the reference location is a frequency domain unit.

[0455] As an example, the reference location is common resource block 0.

[0456] As an example, the starting position of the first frequency block set is the frequency domain unit with the earliest frequency domain position in one of the frequency blocks in the first frequency block set.

[0457] As an example, in the appendix Figure 10 In (1), the starting position of the first frequency block set is resource unit 0.

[0458] As an example, the starting position of the first frequency block set is the frequency domain unit with the earliest frequency domain position in the first frequency block set.

[0459] As an example, the first order is: the frequency domain position from low to high; the first one refers to: the lowest.

[0460] As an example, the first order is: the order of frequency domain positions from high to low; the "most forward" refers to: the highest.

[0461] As an example, N3 is configurable.

[0462] As an example, N3 is equal to the total number of frequency domain units in the first frequency block set.

[0463] As an example, T can be obtained based on N1 and N3.

[0464] As an example, T can be obtained based on N1, N2 and N3.

[0465] As one example, T equals 1; or,

[0466] The T is not less than 2, and the T satisfies: N3 = N1 × (T - 2) + N1 - (N2 mod N1) + tmp; where, if (N2 + N3) mod N1 is not equal to 0, tmp = (N2 + N3) mod N1, otherwise, tmp = N1 (for example, in the appendix...). Figure 10 In (1), N1 equals 4, N2 mod 4 = 2, N3 equals K; and T satisfies: K = 4(T - 2) + 5.

[0467] Example 11

[0468] Example 11 illustrates a schematic diagram of how the number of actual sub-bands included in a first nominal frequency band according to an embodiment of this application depends on the distribution of the first nominal frequency band in a first frequency block set, as shown in the attached diagram. Figure 11 As shown. In the appendix Figure 11 In the diagram, each box represents a frequency domain unit, and the gray-filled boxes and blank boxes represent frequency domain units in different frequency blocks of the first frequency block set, respectively.

[0469] In Embodiment 11, the first nominal frequency band spans two frequency blocks in the first frequency block set (the first nominal frequency band includes eight frequency domain units); the first nominal frequency band includes two actual sub-bands, one of the two actual sub-bands includes two frequency domain units in one of the two frequency blocks, and the other actual sub-band includes six frequency domain units in the other of the two frequency blocks.

[0470] As an example, the first nominal frequency band is any nominal frequency band in the set of nominal frequency bands.

[0471] As an example, according to the instructions in the configuration information, the first node reports the CSI for each actual sub-band included in the first nominal frequency band.

[0472] As one embodiment, at least one nominal frequency band in the nominal frequency band set is indicated by configuration information, and the first node reports CSI for each actual sub-band included in each of the at least one nominal frequency band; wherein, the first nominal frequency band is one of the at least one nominal frequency bands.

[0473] As a sub-implementation of the above embodiments, the configuration information is RRC layer information.

[0474] As a sub-example of the above embodiments, the configuration information is reportFreqConfiguration (case-insensitive).

[0475] As a sub-implementation of the above embodiments, the name of the configuration information includes at least one of report and Freq (case-insensitive).

[0476] As a sub-example of the above embodiments, the configuration information is csi-ReportingBand (case-insensitive).

[0477] As a sub-implementation of the above embodiments, the name of the configuration information includes at least one of csi, Reporting, and Band (case-insensitive).

[0478] As a sub-implementation of the above embodiments, the first nominal frequency band is any one of the at least one nominal frequency bands.

[0479] In addition to the situation shown in Example 11, the following situations may also exist: 1) the first nominal frequency band does not span frequency blocks in the first frequency block set; 2) the first nominal frequency band spans more than two frequency blocks in the first frequency block set.

[0480] As an example, when all frequency domain units included in the first nominal frequency band are frequency domain units in the same frequency block in the first frequency block set, the first nominal frequency band does not span frequency blocks in the first frequency block set.

[0481] As one embodiment, the first nominal frequency band does not span frequency blocks in the first frequency block set, including: among all frequency domain units included in the first nominal frequency band, there are no frequency domain units in different frequency blocks in the first frequency block set.

[0482] As an example, when the first nominal frequency band includes at least one frequency domain unit in one frequency block of the first frequency block set and at least one frequency domain unit in another frequency block of the first frequency block set, the first nominal frequency band spans at least two frequency blocks in the first frequency block set.

[0483] As one embodiment, the first frequency block set includes a plurality of frequency blocks; the first nominal frequency band spans W (where W is any one of 2 to W0, and W0 is equal to the total number of frequency blocks included in the first frequency block set) frequency blocks in the first frequency block set, which includes the following meanings:

[0484] The first set of frequency blocks includes a subset of frequency blocks, the number of which is equal to W; any frequency domain unit in the first nominal frequency band is a frequency domain unit in a frequency block within the subset of frequency blocks; and for any frequency block in the subset of frequency blocks, the first nominal frequency band includes at least one frequency domain unit in that frequency block.

[0485] As an example, for any actual sub-band included in the first nominal frequency band, all frequency domain units included in this actual sub-band are frequency domain units in the same frequency block in the first set of frequency blocks.

[0486] As an example, for any actual sub-band included in the first nominal frequency band, there are no frequency domain units in different frequency blocks of the first frequency block set among all the frequency domain units included in this actual sub-band.

[0487] As an example, the distribution of the first nominal frequency band in the first frequency block set includes: whether the first nominal frequency band spans at least two frequency blocks in the first frequency block set.

[0488] As an example, when the first nominal frequency band spans at least two frequency blocks in the first frequency block set, the first nominal frequency band includes at least two actual sub-bands.

[0489] As a sub-example of the above embodiment, there are two frequency blocks in the first frequency block set that are in the same frequency band.

[0490] As a sub-implementation of the above embodiments, any two frequency blocks in the first frequency block set are not in the same frequency band.

[0491] As a sub-implementation of the above embodiments, when the first nominal frequency band spans W frequency blocks in the first frequency block set, the number of actual sub-bands included in the first nominal frequency band is equal to W; wherein, W is equal to or greater than 2.

[0492] As a sub-implementation of the above embodiments, when the first nominal frequency band does not span frequency blocks in the first frequency block set, the number of actual sub-bands included in the first nominal frequency band is equal to 1.

[0493] As an example, the number of actual sub-bands included in the first nominal frequency band is equal to 1, and the frequency domain units included in the first nominal frequency band are exactly the same as the frequency domain units included in the actual sub-bands included in the first nominal frequency band.

[0494] As an example, the frequency domain units included in the first nominal frequency band are all frequency domain units in the first frequency block set.

[0495] As an example, any frequency domain unit included in a nominal frequency band belongs to an actual sub-band included in the nominal frequency band; and a frequency domain unit included in a nominal frequency band will not belong to both an actual sub-band included in the nominal frequency band and another actual sub-band included in the nominal frequency band.

[0496] As an example, (considering the given frequency domain resources described in this application) there may be a nominal frequency band that includes frequency domain elements that do not belong to the first set of frequency blocks.

[0497] As a sub-implementation of the above embodiments, whether or how frequency domain units that do not belong to the first frequency block set are included does not affect the number of actual sub-bands included in this nominal frequency band.

[0498] As an example, a nominal frequency band is defined for CSI reporting.

[0499] As an example, CSI reporting includes sub-band CQI (Channel Quality Indicator) reporting.

[0500] As an example, CSI reporting includes subband PMI (Precoding Matrix Indicator) reporting.

[0501] As an example, according to the instructions in the configuration information, the first node reports the CQI and / or PMI for each actual sub-band included in the first nominal frequency band.

[0502] As an example, subband CQI and / or PMI reporting is based on the actual subband.

[0503] As an example, in CSI reporting, the subband corresponding to a subband CQI or subband PMI is an actual subband.

[0504] As a sub-implementation of the above embodiments, the nominal frequency band is defined to determine the actual sub-band.

[0505] As an example, it is configurable which actual subbands are reported.

[0506] As an example, for each actual sub-band included in the first nominal frequency band, the first node reports at least one sub-band CQI.

[0507] As a sub-implementation of the above embodiments, the at least one sub-band CQI is a sub-band CQI.

[0508] As a sub-implementation of the above embodiments, the at least one sub-band CQI is more than one sub-band CQI, and the at least one sub-band CQI is for different codewords.

[0509] As an example, for each actual sub-band included in the first nominal frequency band, the first node reports a sub-band PMI.

[0510] As an example, how to calculate the corresponding CQI or select the corresponding PMI for a given actual sub-band is implementation-related and can be determined by the equipment manufacturer.

[0511] As an example, given an actual sub-band, the corresponding CQI can be calculated based on existing techniques in the art.

[0512] As an example, given an actual sub-band, the selection of the corresponding PMI can be determined based on existing technology in the art.

[0513] As an example, common schemes for determining the precoding matrix (and the corresponding subband PMI, subband CQI) include maximizing spatial projection or maximizing channel capacity, etc.; a typical but non-limiting implementation is described below:

[0514] The first node first measures the downlink RS (Reference Signal) within a given actual subband to obtain the original channel matrix H. r×t Where r and t are the number of receiving antennas and the number of antenna ports used for transmitting, respectively; when using the precoding matrix W t×l Under these conditions, the encoded channel parameter matrix is ​​H r×t ·W t×lWhere l is the rank or the number of layers; H is calculated using criteria such as SINR (Signal Interference Noise Ratio), EESM (Exponential Effective SINR Mapping), or RBIR (Received Block Mean Mutual Information Ratio). r×t ·W t×l The equivalent channel capacity;

[0515] Furthermore, the calculation of the equivalent channel capacity can also take into account the noise and interference estimated by the first node. If the downlink RS includes RS resources for interference measurement, the first node can utilize these RS resources to measure the interference or noise more accurately.

[0516] The first node selects the precoding matrix corresponding to the maximum equivalent channel capacity from the valid codebook; the corresponding PMI indicates the precoding matrix corresponding to the maximum equivalent channel capacity; the corresponding CQI is determined by the equivalent channel capacity through table lookup or other methods.

[0517] Example 12

[0518] Example 12 illustrates a schematic diagram showing the relationship between the number of actual sub-bands included in the first nominal frequency band and the first frequency block set according to an embodiment of this application, as shown in the attached diagram. Figure 12 As shown.

[0519] In embodiment 12, the number of actual subbands included in the first nominal frequency band depends on the frequency domain positional relationship between at least two frequency blocks in the first frequency block set and the distribution of the first nominal frequency band in the first frequency block set.

[0520] As an example, the frequency domain positional relationship between the at least two frequency blocks in the first frequency block set includes whether the at least two frequency blocks in the first frequency block set belong to the same frequency band.

[0521] As one embodiment, the number of actual sub-bands included in the first nominal frequency band depends on the distribution of the first nominal frequency band in the first frequency block set and the frequency domain positional relationship between the frequency blocks in the first frequency block set, including:

[0522] The number of actual subbands included in the first nominal frequency band depends on whether the first nominal frequency band spans frequency blocks that do not belong to the same frequency band in the first frequency block set.

[0523] As an example, when the first nominal frequency band spans frequency blocks in the first frequency block set that do not belong to the same frequency band, the first nominal frequency band includes at least two actual sub-bands.

[0524] As a sub-implementation of the above embodiments, when the first nominal frequency band does not span frequency blocks that do not belong to the same frequency band in the first frequency block set, the number of actual sub-bands included in the first nominal frequency band is equal to 1.

[0525] As a sub-implementation of the above embodiments, when the first nominal frequency band spans at least W1 frequency blocks belonging to W1 different frequency bands in the first frequency block set (there may be multiple frequency blocks belonging to the same frequency band), the actual number of sub-bands included in the first nominal frequency band is W1.

[0526] Wherein, W1 is equal to or greater than 2; for any actual sub-band included in the first nominal frequency band, all frequency domain units included in this actual sub-band are within the same frequency band.

[0527] As an example, the advantages of the above method include: it helps to ensure the actual sub-band division between different frequency bands while avoiding unnecessary actual sub-band division within the same frequency band, thus balancing the effectiveness and efficiency of CSI reporting.

[0528] As an example, the following two situations both belong to the case where the first nominal frequency band does not cross frequency blocks that do not belong to the same frequency band in the first frequency block set: 1) The first nominal frequency band does not cross frequency blocks in the first frequency block set; 2) All frequency blocks in the first frequency block set that the first nominal frequency band crosses belong to the same frequency band.

[0529] As an example, multiple frequency bands can be predefined.

[0530] As an example, a frequency band is a frequency range.

[0531] As an example, a frequency band is a range of frequencies defined by a set of RF (Radio Frequency) requirements.

[0532] As an example, a frequency band can be an NR (New Radio) band, or a band defined in the 6G protocol.

[0533] As an example, there is no frequency domain overlap between different frequency bands.

[0534] As an example, any frequency block in the first set of frequency blocks is contained within a frequency band.

[0535] As an example, the frequency domain positional relationship between the at least two frequency blocks in the first frequency block set includes whether the at least two frequency blocks in the first frequency block set are continuous.

[0536] As one embodiment, the number of actual sub-bands included in the first nominal frequency band depends on the distribution of the first nominal frequency band in the first frequency block set and the frequency domain positional relationship between the frequency blocks in the first frequency block set, including:

[0537] The number of actual subbands included in the first nominal frequency band depends on whether the first nominal frequency band spans discontinuous frequency blocks in the first frequency block set.

[0538] As an example, when the first nominal frequency band spans discontinuous frequency blocks in the first frequency block set, the first nominal frequency band includes at least two actual sub-bands.

[0539] As a sub-implementation of the above embodiments, when the first nominal frequency band does not span discontinuous frequency blocks in the first frequency block set, the number of actual sub-bands included in the first nominal frequency band is equal to 1.

[0540] As a sub-implementation of the above embodiment, when the first nominal frequency band spans W2 frequency blocks in the first frequency block set, the W2 frequency blocks form W3 frequency block groups according to their continuity (wherein, all frequency blocks in each frequency block group are sequentially continuous, and (if W3 is greater than 1) any two frequency blocks belonging to different frequency block groups are not continuous), and the actual number of sub-bands included in the first nominal frequency band is W3.

[0541] Wherein, W2 is equal to or greater than 2, and W3 is equal to or greater than 1; for any actual sub-band included in the first nominal frequency band, all frequency domain units included in this actual sub-band are within the same frequency block group.

[0542] It should be noted that the above-mentioned grouping of frequency blocks is not a restrictive method, but is introduced to illustrate the determination result of the actual sub-bands included in the first nominal frequency band; other methods that can obtain the determination result of the above-mentioned actual sub-bands are also acceptable.

[0543] As an example, the advantages of the above method include: it helps to ensure the actual subband division for discontinuous frequency blocks while avoiding unnecessary actual subband division for continuous frequency blocks, thus balancing the effectiveness and efficiency of CSI reporting.

[0544] As an example, the following two situations both belong to the case where the first nominal frequency band does not cross discontinuous frequency blocks in the first frequency block set: 1) The first nominal frequency band does not cross frequency blocks in the first frequency block set; 2) All frequency blocks in the first frequency block set crossed by the first nominal frequency band are continuous.

[0545] As an example, if the frequency domain interval between two frequency blocks is greater than a given threshold, then the two frequency blocks are not contiguous; otherwise, the two frequency blocks are contiguous.

[0546] As an example, several frequency blocks are arranged sequentially and continuously in the frequency domain (with no frequency domain overlap between any two frequency blocks); if the frequency domain interval between any two adjacent frequency blocks is not greater than a given threshold, then the several frequency blocks are sequentially and continuously arranged; otherwise, the several frequency blocks are not considered to be sequentially and continuously arranged.

[0547] The above description of sequential continuity applies to the case where the number of frequency blocks included in the plurality of frequency blocks is equal to or greater than 2.

[0548] As an example, the given threshold is predefined.

[0549] As an example, the given threshold is configurable.

[0550] As an example, the given threshold is equal to a bandwidth.

[0551] As an example, any frequency domain unit included in a nominal frequency band belongs to an actual sub-band included in the nominal frequency band; and a frequency domain unit included in a nominal frequency band will not belong to both an actual sub-band included in the nominal frequency band and another actual sub-band included in the nominal frequency band.
