Description

Methods and apparatus for wireless communication Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0002] In traditional wireless communication, terminals supporting carrier aggregation technology can send and receive data from multiple carriers in multiple cells; however, a physical channel transmits on only one carrier. Carrier aggregation technology can enable terminals to obtain greater service bandwidth and higher transmission rates, but it is not efficient in utilizing fragmented spectrum resources.

[0003] Supporting the configuration of multiple carriers within the same serving cell and allowing cross-carrier physical channel transmission within that same serving cell not only enables large service bandwidth and high transmission rates but also effectively improves the utilization efficiency of fragmented spectrum resources and reduces base station energy consumption. Considering the above scenario, it is essential to research techniques for optimizing physical channel transmission using different carrier configurations. Summary of the Invention

[0004] Optimizing physical channel transmission by utilizing rate matching configurations of different carriers is a problem worthy of study. To address this problem, this application discloses a solution. It should be noted that while the motivation for this application primarily stems from scenarios involving multiple carriers configured within the same serving cell, it is also applicable to other scenarios supporting cross-carrier physical channel configurations. Furthermore, adopting a unified solution can reduce implementation complexity or cost, or improve performance. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0009] In this process, the rate matching of different parts of the first physical channel in the resource mapping depends on different rate matching configurations, and the different rate matching configurations are configured for different carriers.

[0010] 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.

[0011] As an example, the transmission of the first physical channel includes the transmission of the different portions of the first physical channel.

[0202] Example 3

[0203] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and control plane according to this application, as shown in Figure 3. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3 shows the radio protocol architecture for a control plane 300 between a user node device (UE or RSU in V2X, onboard equipment or onboard communication module) and a network node device (gNB, UE or RSU in V2X, onboard equipment or onboard communication module), or between two UEs, 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. Layer 1 will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the user node device and the network node device, as well as between two UEs, through PHY 301. Layer 2 (L2) 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 devices. The PDCP sublayer 304 provides data encryption and integrity protection, and also supports inter-cell mobility between user nodes and network nodes. The RLC sublayer 303 provides packet segmentation and reassembly, retransmission of lost packets via ARQ, and duplicate packet detection and protocol error detection. The MAC sublayer 302 provides mapping between logical and transport channels and multiplexing of logical channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among user nodes. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane 300, the RRC (Radio Resource Control) sublayer 306 of Layer 3 (L3) 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 the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for user node devices and network node devices in the user plane 350 is largely the same as the corresponding layers and sublayers in the 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 data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not illustrated, the user node equipment 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., a remote UE, server, etc.).

[0216] Example 4

[0217] Example 4 illustrates a hardware module schematic diagram of a communication node according to an embodiment of this application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0218] 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.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0336] As an example, from the frequency domain perspective, the first portion of the first physical channel may occupy all or part of the bandwidth of the first carrier.

[0337] As an example, from the frequency domain perspective, the second part of the first physical channel may occupy all or part of the bandwidth of the second carrier.

[0338] Example 8

[0339] Example 8 illustrates a schematic diagram illustrating the relationship between a given portion of a first physical channel and a given rate matching configuration according to an embodiment of the present application, as shown in Figure 8.

[0340] In Example 8, the rate matching of a given portion of the first physical channel in the resource mapping depends on a given rate matching configuration.

[0341] As an example, how the given rate matching configuration is configured will affect the resource mapping of the given portion of the first physical channel.

[0342] As an example, the given portion of the first physical channel may be either the first portion of the first physical channel or the second portion of the first physical channel.

[0343] As an example, the given portion of the first physical channel is the first portion of the first physical channel, and the given rate matching configuration is the first rate matching configuration.

[0344] As an example, the given portion of the first physical channel is the first portion of the first physical channel, and the given rate matching configuration can be either the first rate matching configuration or the third rate matching configuration.

[0345] As an example, the given portion of the first physical channel is the second portion of the first physical channel, and the given rate matching configuration is the second rate matching configuration.

[0346] As an example, the given portion of the first physical channel is the second portion of the first physical channel, and the given rate matching configuration can be either the second rate matching configuration or the third rate matching configuration.

[0347] As one embodiment, rate matching of the given portion of the first physical channel (which may be the first portion or the second portion) in resource mapping includes: which resources are used for mapping in the resource mapping performed during the transmission that generates the given portion of the first physical channel.

[0348] As one embodiment, the resource mapping includes mapping modulation symbols to time-frequency resources.

[0349] As one embodiment, the resource mapping includes mapping to virtual resource blocks.

[0350] As one embodiment, the resource mapping includes mapping to resource elements.

[0351] As an example, resources indicated by the given rate matching configuration are skipped in the resource mapping performed during the transmission of the given portion of the first physical channel.

[0352] As one embodiment, the rate matching of a given portion of the first physical channel (which may be the first portion or the second portion) in the resource mapping depends on a given rate matching configuration, including: skipping at least the resources indicated by the given rate matching configuration in the resource mapping performed during the transmission of the given portion of the first physical channel.

[0353] As an example, the resources indicated by the given rate matching configuration are not used to map the given portion of the first physical channel.

[0354] As an example, the transmission of the given portion of the first physical channel is generated by coded bits after at least modulation and resource mapping.

[0355] As an example, the transmission of the given portion of the first physical channel is generated by the coded bits after at least scrambling, modulation, layer mapping, antenna port mapping, mapping to virtual resource blocks, and mapping from virtual to physical resource blocks.

[0356] As an example, the coded bits mentioned above include at least a portion of all coded bits to be transmitted over the first physical channel.

[0357] As an example, the different portions of the first physical channel can be used to transmit different portions of all the coded bits to be transmitted on the first physical channel.

[0358] As an example, in the mapping to virtual resource blocks, for each antenna port of the given portion used to transmit the first physical channel, the generated modulation symbol sequence is sequentially mapped to resource elements in the allocated virtual resource blocks for transmission that satisfy all conditions in the first condition set.

[0359] Wherein, at least one condition in the first set of conditions depends on the given rate matching configuration.

[0360] As one embodiment, the order can be as follows: first, the increasing order of the subcarrier index across the allocated virtual resource blocks, then the increasing order of the time-domain symbol index.

[0361] As an example, a time-domain symbol is a time-domain unit defined in a time-domain structure.

[0362] As an example, a time-domain symbol is a time-domain unit defined in the frame structure.

[0363] As an example, a time-domain symbol is an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0364] As an example, a time-domain symbol can also be a single-carrier symbol or a multi-carrier symbol, such as a DFT-S-OFDM (Discrete Fourier Transform Spread OFDM) symbol or an FBMC (Filter Bank Multi Carrier) symbol.

[0365] As an example, a time-domain symbol is a symbol in a time slot.

[0366] As an example, the order can also be based on other predefined sorting rules, and how it is specifically defined does not affect the technical advantages of the solution disclosed in this application.

[0367] As an example, one of the conditions in the first set of conditions includes: the corresponding resource unit in the corresponding physical resource block does not belong to the resource indicated by the given rate matching configuration.

[0368] As an example, one of the conditions in the first set of conditions is that the corresponding resource unit in the corresponding physical resource block does not belong to the resource indicated by the given rate matching configuration.

[0369] As an example, one of the conditions in the first set of conditions is that the corresponding resource unit in the corresponding physical resource block is not available for transmission of the first type of physical channel;

[0370] Wherein, the resources indicated by the given rate matching configuration cannot be used for transmission on the first type of physical channel, and the first physical channel belongs to the first type of physical channel.

[0371] As an example, the advantages of the above method include: utilizing the existing 3GPP framework and making improvements on it, resulting in less standardization work.

[0372] As an example, in addition to the given rate matching configuration indicating resources that are not available for transmission on the first type of physical channel, there may be other configurations indicating resources that are not available for transmission on the first type of physical channel.

[0373] As a sub-example of the above embodiment, the other configurations may be other rate matching configurations.

[0374] As an example, the first type of physical channel is used to transmit user data.

[0375] As an example, the channel used to transmit DL-SCH data belongs to the first type of physical channel.

[0376] As an example, PDSCH belongs to the first type of physical channel.

[0377] As an example, the channel used to transmit UL-SCH data belongs to the first type of physical channel.

[0383] As an example, the first set of conditions further includes the following condition: the corresponding resource unit in the corresponding physical resource block is not used to transmit a specific reference signal(s).

[0384] As one example, the specific reference signal includes non-zero-power CSI-RS (Channel State Information Reference Signal).

[0385] As one example, the specific reference signal includes PT-RS (Phase-Tracking Reference Signal).

[0386] As one example, the specific reference signal includes DM-RS (Demodulation Reference Signal).

[0387] As an example, virtual resource blocks and physical resource blocks can be mapped in a non-interleaved manner.

[0388] As an example, virtual resource block n1 is mapped to physical resource block n2; wherein, n1 is the index of the virtual resource block, n2 is the index of the physical resource block, and n2 is equal to n1.

[0389] As an example, virtual resource block n1 is mapped to physical resource block n2; wherein, n1 is the index of the virtual resource block, n2 is the index of the physical resource block, n2 is equal to n1 plus Q, and Q is the index of the physical resource block with the smallest index in the control resource set (CORESET) that receives the first signaling.

[0390] As an example, virtual resource blocks and physical resource blocks can also be mapped in an interleaved manner.

[0391] As an example, the resources indicated by the given rate matching configuration are resources that are unavailable for transmission of the given portion of the first physical channel.

[0392] As an example, the resources indicated by the given rate matching configuration are not used for transmission on a first type of physical channel, which belongs to the first type of physical channel.

[0393] As an example, the resources indicated by the given rate matching configuration include time-frequency resources.

[0394] As an example, the resource indicated by the given rate matching configuration includes resource elements.

[0395] As an example, the given rate matching configuration includes the configuration of a rate matching pattern.

[0396] As an example, the given rate matching configuration is a configuration of the rate matching mode.

[0397] As an example, the given rate matching configuration includes at least one rate matching mode ID (Identifier), which indicates the corresponding rate matching mode.

[0398] As an example, for a rate matching mode, refer to 3GPP TS 38.331V18.0.0.

[0399] As an example, in a rate-matching mode, resources can be indicated by a bitmap(s).

[0400] As a sub-implementation of the above embodiments, different bitmaps can respectively indicate time-domain resources (e.g., time-domain symbols, time-domain repetition patterns) and frequency-domain resources (e.g., resource blocks).

[0401] As an example, the name of the configuration signaling for the given rate matching configuration includes at least one of Rate and Match and Pattern (case-insensitive).

[0402] As one example, the given rate matching configuration includes RateMatchPattern.

[0403] As an example, the given rate matching configuration includes at least one RateMatchPattern ID, which indicates the resource configured in the corresponding RateMatchPattern.

[0404] As an example, the resources indicated by the given rate matching configuration include zero-power CSI-RS (Zero-Power(ZP)CSI-RS) resources.

[0405] As an example, the given rate matching configuration includes the configuration of zero-power CSI-RS resources (ZP CSI-RS resource(s)).

[0406] As an example, the given rate matching configuration is the configuration of a zero-power CSI-RS resource(s) (ZP CSI-RS resource(s)).

[0407] As one example, the given rate matching configuration includes the configuration of a set of zero-power CSI-RS resources.

[0408] As an example, the definition of the set of zero-power CSI-RS resources can be found in 3GPP TS 38.331V18.0.0.

[0409] As one example, the given rate matching configuration includes ZP-CSI-RS-Resource.

[0410] As one example, the given rate matching configuration includes ZP-CSI-RS-ResourceSet.

[0413] As an example, the name of the configuration signaling for the given rate matching configuration includes at least one of ZP and CSI-RS (case-insensitive).

[0414] As an example, a zero-power CSI-RS configuration can be for a single carrier or across multiple carriers.

[0415] Example 9

[0416] Example 9 illustrates a schematic diagram of skipping at least resources specified in a given rate matching configuration indication during resource mapping in a transmission generating a given portion of a first physical channel, according to an embodiment of this application, as shown in Figure 9. In Figure 9, the gray portion represents the given portion of the first physical channel, and the four white rectangular portions each represent resources skipped during resource mapping in the transmission generating the given portion of the first physical channel; wherein the skipped resources include at least a portion of the resources specified in the given rate matching configuration indication, and no resources belonging to the resources specified in the given rate matching configuration indication exist in the gray portion.

[0417] As an example, Figure 9 shows the final effect after mapping to physical resources; in resource mapping, the operations related to the resource indicated by the given rate matching configuration are skipped and executed before the mapping to physical resources is completed (e.g., the related operations can be executed in the step of mapping to virtual resource blocks, or in the step of mapping to physical resources, etc.; these methods can achieve the same final mapping effect to physical resources).

[0418] As an example, in the resource mapping performed during the transmission of the given portion of the first physical channel,

[0419] The skipping of the resources indicated by the given rate matching configuration includes: skipping the portion of all resources indicated by the given rate matching configuration that overlaps with the resources allocated to the given portion of the first physical channel.

[0420] As a sub-implementation of the above embodiment, among all the resources indicated by the given rate matching configuration, there may also be some resources that do not overlap with the resources allocated to the given portion of the first physical channel; these resources generally do not need to be considered in the resource mapping performed during the transmission that generates the given portion of the first physical channel.

[0421] As an example, the resources allocated to the given portion of the first physical channel (these resources can be determined according to the indication of the first signaling) include the gray portion and four white rectangular portions in Figure 9, and the transmission of the given portion of the first physical channel is only in the gray portion.

[0422] As an example, the skipped resources include only a portion of the resources indicated by the given rate matching configuration.

[0423] As an example, the skipped resources may also include other resources, such as resources indicated by a rate matching configuration other than the given rate matching configuration, or resources used to transmit some reference signals.

[0424] As one embodiment, the given portion of the first physical channel is the first portion of the first physical channel, and the skipped resources include at least a portion of the resources indicated by the first rate matching configuration.

[0425] As an example, the given portion of the first physical channel is the first portion of the first physical channel, and the skipped resources include at least a portion of the resources indicated by the first rate matching configuration and at least a portion of the resources indicated by the third rate matching configuration.

[0426] As one embodiment, the given portion of the first physical channel is the second portion of the first physical channel, and the skipped resources include at least a portion of the resources indicated by the second rate matching configuration.

[0427] As an example, the given portion of the first physical channel is the second portion of the first physical channel, and the skipped resources include at least a portion of the resources indicated by the second rate matching configuration and at least a portion of the resources indicated by the third rate matching configuration.

[0428] Example 10

[0429] Example 10 illustrates a schematic diagram showing that the rate matching of different parts of the first physical channel in the resource mapping according to an embodiment of the present application all depend on a third rate matching configuration, as shown in Figure 10.

[0430] In embodiment 10, the rate matching of the first portion of the first physical channel in the resource mapping depends on a third rate matching configuration, and the rate matching of the second portion of the first physical channel in the resource mapping depends on the third rate matching configuration; the third rate matching configuration is a rate matching configuration other than the different rate matching configurations.

[0431] As an example, the third rate matching configuration is a rate matching configuration other than the first rate matching configuration and the second rate matching configuration.

[0432] As an example, the third rate matching configuration is at least for the first carrier and the second carrier.

[0433] As an example, the third rate matching configuration is configured across at least the first carrier and the second carrier.

[0434] As an example, from a frequency domain perspective, the resources indicated by the third rate matching configuration include at least the resources on the first carrier and the resources on the second carrier.

[0435] As an example, from a frequency domain perspective, the resources indicated by the third rate matching configuration span at least the first carrier and the second carrier.

[0436] As an example, the advantages of the above method include: rate matching configuration on multiple carriers can be configured using the same rate matching configuration signaling, which can effectively save the overhead of configuration signaling in appropriate scenarios.

[0437] As an example, the third rate matching configuration is configured by a signaling that is only used to configure rate matching.

[0438] As an example, the first signaling or higher-level signaling instructs the third rate matching configuration for rate matching.

[0439] As an example, in the first signaling, a field other than the first field indicates that the third rate matching configuration is used for rate matching.

[0440] Example 11

[0441] Example 11 illustrates a schematic diagram of a candidate mapping of the value of a first field according to an embodiment of the present application, as shown in Figure 11.

[0442] In embodiment 11, each candidate value of the first domain is mapped to a set of rate matching configurations; the candidates for the value of the first domain include the first value, and the set of rate matching configurations to which the first value is mapped includes the different rate matching configurations;

[0443] Wherein, the first signaling includes the first field, and the value of the first field in the first signaling is the first value.

[0444] As an example, the first field includes 1 bit, and the candidates for the value of the first field include 0 and 1.

[0445] As an example, the first field comprises 2 bits, and the candidates for the value of the first field include at least a portion of 00, 01, 10, and 11.

[0446] As a sub-implementation of the above embodiment, when one of the values ​​00, 01, 10, and 11 is not mapped to a rate matching configuration set (e.g., the value has no corresponding indication or is reserved), this value does not belong to the candidate values ​​of the first field; it should be noted that the above description is for the case where the first field includes 2 bits, and a similar description can be given for the case where the first field includes more bits.

[0447] As an example, the first field may include more than two bits.

[0448] As an example, the first value is one of the candidates for the value of the first domain.

[0449] As an example, the rate matching configuration set to which the first value is mapped also includes the third rate matching configuration.

[0450] As an example, a rate matching configuration set includes at least one rate matching configuration.

[0451] As an example, a rate matching configuration set may include which / which rate matching configurations can be configured or predefined.

[0452] As an example, the mapping relationship between a candidate value of the first domain and the corresponding rate matching configuration set can be determined according to predefined rules.

[0453] As one embodiment, the different rate matching configurations include the first rate matching configuration and the second rate matching configuration.
