Communication method and related apparatus

[0001] This application claims priority to the Chinese Patent Application No. CN202411254808.2, filed on September 6, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and in particular, to a communication method and related apparatus. BACKGROUND

[0003] Wireless communication can be transmission communication between two or more communication devices without propagation through a conductor or cable. Generally, the two or more communication devices include a network device and a terminal device, or the two or more communication devices include different terminal devices.

[0004] Currently, in the communication process of different communication devices, a data sender can send data through a data channel, and correspondingly, a data receiver can receive data through the data channel to implement a data transmission process.

[0005] However, in the above data transmission process, how to improve the data transmission performance is a technical problem to be solved. SUMMARY

[0006] The present application provides a communication method and related apparatus for improving data transmission performance.

[0007] The first aspect of the present application provides a communication method, which is applied to a first communication device, such as being executed by the first communication device. The first communication device can be a communication device (such as a terminal device or a network device), or the first communication device can be a part of the communication device (for example, a circuit or a chip responsible for communication function (such as a Modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core) and the like), or the first communication device can also be a logic module or software capable of realizing all or part of the communication device function.

[0008] In the method, the first communication device receives first configuration information, the first configuration information being used for configuring first resources of a first data channel; the first communication device receives second configuration information, the second configuration information being used for configuring second resources; and the first communication device transmits or receives the first data channel on third resources, the third resources being included in the first resources and not including the second resources.

[0009] Based on the above scheme, the first configuration information received by the first communication device is used for configuring first resources of a first data channel, and the second configuration information received by the first communication device is used for configuring second resources; and then the first communication device transmits or receives the first data channel on third resources in the first resources, the third resources not including the second resources. In this way, the first communication device can implement transmission of the data channel on the third resources in the first resources except for the specified second resources, and can avoid or reduce mutual influence and / or mutual interference between transmission of the data channel and transmission of other signals on the second resources, so as to improve data transmission performance.

[0010] Optionally, the third resources are included in the first resources, which can be understood as that the third resources are resources in the first resources, or the third resources are a subset of the first resources, or the third resources include one or more resource units located in the first resources.

[0011] Optionally, the third resources do not include the second resources, which can be understood as that among one or more resource units included in the third resources, there is at least one resource unit different from one or more resource units included in the second resources; or the one or more resource units included in the third resources are different from the one or more resource units included in the second resources; or the resources in the third resources do not include the resources in the second resources.

[0012] It should be noted that the first communication device transmits or receives the first data channel on the third resources, which can be understood as that the first communication device receives data and / or signals of the first data channel on the third resources, or the first communication device transmits data and / or signals of the first data channel on the third resources.

[0013] As an example, taking the process of receiving the first data channel by the first communication device as an example. In the process, the first communication device can determine the second resources (i.e., time-frequency resources on which data is not mapped) according to the second configuration information, and when the first communication device receives data on the first data channel, the first communication device can receive data on the third resources not including the second resources; in other words, the sending end can perform rate matching on data based on the second resources, i.e., the sending end can not transmit data on the second resources, and correspondingly, the first communication device can not receive data on the second resources.

[0014] As another example, taking the process that the first communication device transmits the first data channel as an example. In this process, the first communication device can determine the second resource (i.e., the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication device transmits data on the first data channel, the first communication device can transmit data on the third resource excluding the second resource; in other words, the first communication device can rate-match data based on the second resource, i.e., the first communication device can not transmit data on the second resource, and correspondingly, the receiving end can not receive data on the second resource.

[0015] From the above process, it can be seen that for the transceiver, the second resource can be a time-frequency resource on which data is not mapped.

[0016] For example, for the sending end, the sending end does not map data on the second resource (or determines not to map data on the second resource) through rate matching.

[0017] For another example, for the sending end, the sending end can puncture (or delete, ignore, etc.) the bits carried by the second resource after mapping data on the first resource.

[0018] For another example, for the receiving end, the receiving end can receive data on the third resource excluding the second resource.

[0019] For another example, for the receiving end, the receiving end ignores (or skips) one or more resource units in the first resource that overlap with the second resource in the process of receiving data on the first resource.

[0020] Optionally, in the above process, the communication device that communicates with the first communication device on the first data channel can be a communication device (e.g., the second communication device) that sends the first configuration information to the first communication device, or can be another communication device, which is not limited here.

[0021] It should be noted that the second resource can be implemented in various ways, which will be described below in conjunction with some examples.

[0022] Mode A, the time domain position of the second resource is different from the time domain position of the demodulation reference signal (DMRS) of the first data channel; the resource pattern of the second resource includes at least one of the following modes A-1 to A-5.

[0023] Mode A-1. The resource pattern of the second resource includes the 0th subcarrier, the 4th subcarrier, and the 8th subcarrier in one frequency domain unit.

[0024] Manner A-2. The resource pattern of the second resource includes the 0th, 1st, 6th and 7th subcarriers in one frequency domain unit.

[0025] Manner A-3. The resource pattern of the second resource includes the 2nd, 3rd, 8th and 9th subcarriers in one frequency domain unit.

[0026] Manner A-4. The resource pattern of the second resource includes the 4th, 5th, 10th and 11th subcarriers in one frequency domain unit.

[0027] Manner A-5. The resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0028] According to the manner A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel, i.e., the third resource of the first data channel transmitted by the first communication device does not include the second resource in the time domain position other than the time domain position of the DMRS of the first data channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0029] For example, in the above-mentioned manner A-1, the resource pattern of the second resource is the same as the resource pattern of the physical broadcast channel (PBCH) DMRS in new radio (NR) or 5G. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced by the manner A-1.

[0030] For another example, in the above-mentioned manner A-2, A-3 or A-4, the resource pattern of the second resource is the same as the resource pattern of the physical downlink shared channel (PDSCH) DMRS in NR (or 5G, or 5G NR). Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH DMRS on the second resource can be avoided or reduced by the manner A-2, A-3 or A-4.

[0031] For example, in the above-described manner A-5, the resource pattern of the second resource is the same as the resource pattern of a PDSCH phase noise tracking reference signal (PTRS) in NR (or 5G, or 5G NR); thus, by means of the manner A-5, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0032] Optionally, the third resource does not include a DMRS resource of the first data channel; in this way, the influence and / or interference of the transmission of the first data channel on the DMRS resource of the first data channel can be avoided, so as to improve the data demodulation performance of the first data channel.

[0033] The manner B, the resource pattern of the second resource includes the following manner B-1 and / or manner B-2.

[0034] The manner B-1, the resource pattern of the second resource includes the 0th subcarrier, the 4th subcarrier, and the 8th subcarrier in one frequency domain unit.

[0035] The manner B-2, the resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0036] Based on the manner B, the third resource of the first data channel transmitted by the first communication device does not include the second resource of the at least one resource pattern; thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0037] For example, in the above-described manner B-1, the resource pattern of the second resource is the same as the resource pattern of a PBCH DMRS in NR (or 5G, or 5G NR); thus, by means of the manner B-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0038] For example, in the above-described manner B-2, the resource pattern of the second resource is the same as the resource pattern of a PDSCH PTRS in NR (or 5G, or 5G NR); thus, by means of the manner B-2, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0039] In a possible implementation of the first aspect, the method further includes: receiving, by the first communication device, third configuration information, the third configuration information being used to indicate at least one of resource pattern information, code division multiplexing group information, and sequence information of a DMRS of the first data channel.

[0040] Based on the above scheme, the first communication apparatus can further receive third configuration information, so that the first communication apparatus can determine at least one of resource pattern information, code division multiplexing group information, and sequence information of the DMRS of the first data channel through the third configuration information, so as to receive the DMRS on the first data channel based on the at least one and demodulate / parse the data carried on the first data channel based on the received DMRS.

[0041] In a possible implementation manner of the first aspect, the method further includes: the first communication apparatus receiving fourth configuration information, the fourth configuration information being used to indicate that a transport block size (TBS) corresponding to the first data channel is determined based on the third resource.

[0042] Based on the above scheme, the first communication apparatus can further receive fourth configuration information, so that the first communication apparatus can determine that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource through the fourth configuration information, so as to enable the first communication apparatus to implement the reception or transmission of the first data channel based on the TBS associated with the third resource, to improve the accuracy of TBS calculation, and to further improve the transmission performance of the first data channel.

[0043] The second aspect of the present application provides a communication method applied to a second communication apparatus, such as executed by the second communication apparatus. The second communication apparatus can be a communication device (such as a terminal device or a network device), or the second communication apparatus can be part of a component (such as a circuit or a chip responsible for communication functions (such as a Modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core, etc.)) in the communication device, or the second communication apparatus can also be a logic module or software capable of implementing all or part of the functions of the communication device. In the method, the second communication apparatus transmits first configuration information, the first configuration information being used to configure a first resource of a first data channel; the second communication apparatus transmits second configuration information, the second configuration information being used to configure a second resource; wherein the first data channel is carried in a third resource in the first resource, and the third resource does not include the second resource.

[0044] Based on the above scheme, the first configuration information sent by the second communication device to the first communication device is used to configure the first resource of the first data channel, and the second configuration information sent by the second communication device to the first communication device is used to configure the second resource; thereafter, the first communication device transmits or receives the first data channel on the third resource in the first resource, and the third resource does not include the second resource. In this way, the first communication device can implement the transmission of the data channel on the third resource in the first resource except for the specified second resource, and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel and the transmission of other signals on the second resource, so as to improve the data transmission performance.

[0045] It should be noted that the second resource can be implemented in various ways, which will be described below in conjunction with some examples.

[0046] In mode A, the time domain position of the second resource is different from the time domain position of the demodulation reference signal (DMRS) of the first data channel; and the resource pattern of the second resource includes at least one of the following modes A-1 to A-5.

[0047] In mode A-1, the resource pattern of the second resource includes the 0th subcarrier, the 4th subcarrier, and the 8th subcarrier in one frequency domain unit.

[0048] In mode A-2, the resource pattern of the second resource includes the 0th subcarrier, the 1st subcarrier, the 6th subcarrier, and the 7th subcarrier in one frequency domain unit.

[0049] In mode A-3, the resource pattern of the second resource includes the 2nd subcarrier, the 3rd subcarrier, the 8th subcarrier, and the 9th subcarrier in one frequency domain unit.

[0050] In mode A-4, the resource pattern of the second resource includes the 4th subcarrier, the 5th subcarrier, the 10th subcarrier, and the 11th subcarrier in one frequency domain unit.

[0051] In mode A-5, the resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0052] Based on mode A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel, i.e., the third resource of the first data channel transmitted by the first communication device does not include the second resource at other time domain positions except for the time domain position of the DMRS of the first data channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0053] For example, in the above-mentioned manner A-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); for this purpose, by means of the manner A-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0054] For another example, in the above-mentioned manner A-2, A-3 or A-4, the resource pattern of the second resource is the same as the resource pattern of the PDSCH DMRS in NR (or 5G, or 5G NR); for this purpose, by means of the manner A-2, A-3 or A-4, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH DMRS on the second resource can be avoided or reduced.

[0055] For another example, in the above-mentioned manner A-5, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); for this purpose, by means of the manner A-5, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0056] Optionally, the third resource does not include the DMRS resource of the first data channel, by this means, the influence and / or interference of the transmission of the first data channel on the DMRS resource of the first data channel can be avoided, so as to improve the data demodulation performance of the first data channel.

[0057] The manner B, the resource pattern of the second resource includes the following manner B-1 and / or manner B-2.

[0058] The manner B-1, the resource pattern of the second resource includes the 0th subcarrier, the 4th subcarrier, and the 8th subcarrier in one frequency domain unit.

[0059] The manner B-2, the resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0060] Based on the manner B, the third resource of the first data channel transmitted by the first communication device does not include the second resource of the above-mentioned at least one resource pattern. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0061] For example, in the above-mentioned manner B-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); for this purpose, by means of the manner B-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0062] For example, in the above-mentioned manner B-2, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); therefore, by means of manner B-2, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0063] In a possible implementation manner of the second aspect, the method further includes: the second communication apparatus sends third configuration information, the third configuration information being used for indicating at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel.

[0064] Based on the above scheme, the second communication apparatus can further send third configuration information to the first communication apparatus, so that the first communication apparatus can determine at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel through the third configuration information, so as to receive the DMRS on the first data channel based on the at least one, and demodulate / parse the data carried on the first data channel based on the received DMRS.

[0065] In a possible implementation manner of the second aspect, the method further includes: the second communication apparatus sends fourth configuration information, the fourth configuration information being used for indicating that the TBS corresponding to the first data channel is determined based on the third resource.

[0066] Based on the above scheme, the second communication apparatus can further send fourth configuration information to the first communication apparatus, so that the first communication apparatus can determine that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource through the fourth configuration information, so as to enable the first communication apparatus to implement the reception or transmission of the first data channel based on the TBS associated with the third resource, to improve the accuracy of TBS calculation, and to further improve the transmission performance of the first data channel.

[0071] Based on the above scheme, the second configuration information for configuring the second resource can include the at least one of the above to implement configuration of at least one of a resource pattern, a time domain location, or a frequency domain location of the second resource.

[0072] Optionally, the at least one of the resource pattern, the time domain location, or the frequency domain location of the second resource can be preconfigured or protocol predefined to reduce overhead.

[0093] Based on the above scheme, the second information used for determining the frequency domain position of the second resource can include the at least one above, so as to improve the flexibility of the scheme implementation.

[0094] In a possible implementation of the first aspect or the second aspect, the carrier where the first data channel is located is used to determine at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel.

[0095] Based on the above scheme, the DMRS of the first data channel can be used to demodulate / parse data carried by the first data channel, where the carrier where the first data channel is located can be used to determine at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel. In this way, different carriers can have different DMRS configurations. Therefore, the first communication device can implement the reception or transmission of the DMRS based on the DMRS configuration corresponding to the carrier where the data channel is located, so as to improve the reception / parse success rate of the DMRS by the receiver of the DMRS, and further improve the data reception performance.

[0096] Optionally, the third configuration information and the carrier where the first data channel is located described above can be used to jointly determine at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel. For example, the carrier where the first data channel is located is used to determine at least one of one or more resource pattern information, one or more code division multiplexing group information, or one or more sequence information of the DMRS of the first data channel, and the third configuration information is used to indicate at least one of one of the one or more resource pattern information, one of the one or more code division multiplexing group information, or one of the one or more sequence information.

[0097] In a possible implementation of the first aspect or the second aspect, the first data channel is a data channel of a first radio access technology; and the second resource is used to carry a reference signal of a second radio access technology.

[0098] Based on the above scheme, the second resource is used to carry a reference signal of a second radio access technology, and the first data channel on the third resource excluding the second resource is a data channel of a first radio access technology, so that the above scheme can be applied to a scenario of spectrum sharing of two or more radio access technologies (for example, multi radio access technology spectrum sharing (MRSS)), and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel of the first radio access technology and the transmission of the reference signal of the second radio access technology in the scenario, so as to improve the data transmission performance.

[0099] Optionally, the resource pattern information of the reference signal of the first radio access technology can be implemented in various ways.

[0100] As an example, the resource pattern information of the reference signal of the first radio access technology is same as the resource pattern information of the reference signal of the second radio access technology; wherein the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology, and / or the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be same, so that the reference signals of different radio access technologies can be distinguished by different code division multiplexing groups and / or different sequences (e.g. orthogonal sequences), to save resource overhead.

[0101] As another example, the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be different, so that the reference signals of different radio access technologies can be distinguished by different resource patterns, to reduce implementation complexity.

[0102] In a possible implementation form of the first aspect or the second aspect, the transport block size (TBS) corresponding to the first data channel is determined based on the third resource.

[0103] Based on the above scheme, the first communication device can determine that the TBS corresponding to the first data channel is determined based on the third resource which does not include the second resource, so that the first communication device can implement the reception or transmission of the first data channel based on the TBS associated with the third resource, and the reception performance of the receiver can be improved.

[0104] The third aspect of the present disclosure provides a communication method, which is applied to a third communication device, such as being executed by the third communication device. The third communication device can be a communication device (e.g. a terminal device or a network device), or the third communication device can be part of the communication device (e.g. a circuit or a chip responsible for communication function (e.g. a Modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core, etc.), or the third communication device can also be a logic module or software capable of implementing all or part of the functions of the communication device. In the method, the third communication device determines a carrier of a communication, the carrier is used to determine fourth information of a reference signal, the fourth information includes at least one of one or more resource pattern information, one or more code division multiplexing group information, and one or more sequence information; and the third communication device transmits or receives the reference signal based on the fourth information.

[0105] Based on the above scheme, the carrier of the communication can be used to determine at least one of resource pattern information of the reference signal, code division multiplexing group information, and sequence information. In this way, the third communication device can implement the reception or transmission of the reference signal based on the reference signal configuration corresponding to the communication carrier, so as to improve the reception / analysis success rate of the reference signal by the receiving party of the reference signal, and further improve the communication performance.

[0106] Optionally, the reference signal can include one or more of a DMRS (e.g., a PDSCH DMRS, a PBCH DMRS, or a PDCCH DMRS, etc.), a PTRS, a synchronization signal / physical broadcast channel block (SSB or S-SS / PSBCH block), a CSI-RS, a TRS, and a sounding reference signal (SRS).

[0107] Optionally, the resource pattern information of the reference signal of the first radio access technology can be implemented in various ways.

[0108] As an example, the resource pattern information of the reference signal of the first radio access technology is the same as the resource pattern information of the reference signal of the second radio access technology; wherein the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology, and / or the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be the same, so that the reference signals of different radio access technologies can be distinguished by different code division multiplexing groups and / or different sequences (e.g., orthogonal sequences), so as to save resource overhead.

[0109] As another example, the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be different, so that the reference signals of different radio access technologies can be distinguished by different resource patterns, so as to reduce the implementation complexity.

[0110] In a possible implementation of the third aspect, the carrier for the communication is used for communication of at least two radio access technologies. In this way, the above scheme can be applied to a scenario of two or more radio access technology spectrum sharing (for example, MRSS), and the same reference signal configuration is used for different radio access technologies in the scenario, which can improve the communication performance while reducing the implementation complexity.

[0111] In a possible implementation of the third aspect, the carrier for the communication is used for communication of one radio access technology. In this way, different reference signal configurations can exist for different carriers, and the third communication device can use the corresponding reference signal configuration to implement the reception or transmission of the reference signal based on the carrier for the communication of the one radio access technology, which can improve the communication performance while receiving or transmitting the reference signal of different radio access technologies based on different reference signal configurations to improve the transmission performance of the reference signal.

[0112] In a possible implementation of the third aspect, the method further includes: receiving or transmitting, by the third communication device, fifth configuration information, the fifth configuration information being used to indicate at least one of the following: one of the one or more resource pattern information, one of the one or more code division multiplexing group information, or one of the one or more sequence information.

[0113] Based on the above scheme, the third communication device can also receive or transmit the fifth configuration information, so that the receiver of the fifth configuration information can determine the at least one based on the fifth configuration information, and the flexibility of the implementation of the scheme can be improved by using the fifth configuration information to flexibly configure at least one of the resource pattern, the code division multiplexing group, and the sequence.

[0114] The fourth aspect of the present application provides a communication method applied to a first communication device, such as being executed by the first communication device. The first communication device can be a communication device (for example, a terminal device or a network device), or the first communication device can be part of the communication device (for example, a circuit or a chip responsible for the communication function (for example, a Modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core, etc.), or the first communication device can also be a logic module or software capable of implementing all or part of the functions of the communication device. In the method, the first communication device receives first configuration information, the first configuration information being used to configure a first resource of a first data channel; and the first communication device determines a TBS of the first data channel based on a third resource, the third resource being included in the first resource, and the third resource not including a second resource.

[0115] Based on the above scheme, the first configuration information received by the first communication device is used to configure the first resource of the first data channel, and the first communication device transmits or receives the first data channel on the third resource included in the first resource. Wherein, the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, which can improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0116] Optionally, after the first communication device determines the TBS of the first data channel based on the third resource, the first communication device can transmit or receive the first data channel on the third resource included in the first resource, so that the first communication device can realize the reception or transmission of the first data channel based on the actual transmission of the TBS associated with the third resource, which can improve the transmission performance of the first data channel.

[0117] It should be noted that the second resource can be implemented in various ways, which will be described below in conjunction with some examples.

[0118] Option A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel; the resource pattern of the second resource includes at least one of the following options A-1 to A-5.

[0121] Option A-3. The resource pattern of the second resource includes the 2nd subcarrier, the 3rd subcarrier, the 8th subcarrier and the 9th subcarrier in one frequency domain unit.

[0122] Option A-4. The resource pattern of the second resource includes the 4th subcarrier, the 5th subcarrier, the 10th subcarrier and the 11th subcarrier in one frequency domain unit.

[0123] Option A-5. The resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0124] Based on option A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel, that is, the third resource of the first data channel transmitted by the first communication device does not include the second resource at other time domain positions except the time domain position of the DMRS of the first data channel. Therefore, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0125] For example, in the above-mentioned manner A-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); for this purpose, by means of manner A-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0126] For another example, in the above-mentioned manner A-2, A-3 or A-4, the resource pattern of the second resource is the same as the resource pattern of the PDSCH DMRS in NR (or 5G, or 5G NR); for this purpose, by means of manner A-2, A-3 or A-4, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH DMRS on the second resource can be avoided or reduced.

[0127] For another example, in the above-mentioned manner A-5, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); for this purpose, by means of manner A-5, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0128] Optionally, the third resource does not include the DMRS resource of the first data channel, by this means, the influence and / or interference of the transmission of the first data channel on the DMRS resource of the first data channel can be avoided, so as to improve the data demodulation performance of the first data channel.

[0129] Manner B, the resource pattern of the second resource includes the following manner B-1 and / or manner B-2.

[0130] Manner B-1. The resource pattern of the second resource includes the 0th subcarrier, the 4th subcarrier, and the 8th subcarrier in one frequency domain unit.

[0131] Manner B-2. The resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0132] Based on the manner B, the third resource of the first data channel transmitted by the first communication device does not include the second resource of the above-mentioned at least one resource pattern. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0133] For example, in the above-described manner B-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); for this purpose, by means of manner B-1, the mutual influence and / or mutual interference generated between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0134] For another example, in the above-described manner B-2, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); for this purpose, by means of manner B-2, the mutual influence and / or mutual interference generated between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0135] In a possible implementation manner of the fourth aspect, the method further includes: the first communication device receiving fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource.

[0136] Based on the above-described scheme, the first communication device can further receive fourth configuration information, so that the first communication device can determine, through the fourth configuration information, that the TBS corresponding to the first data channel is determined based on the third resource that does not include the second resource, so as to enable the first communication device to implement the reception or transmission of the first data channel based on the TBS associated with the third resource, to improve the accuracy of TBS calculation, and further to improve the transmission performance of the first data channel.

[0137] The fifth aspect of the present application provides a communication method, which is applied to a second communication device, such as being executed by the second communication device. The second communication device can be a communication device (such as a terminal device or a network device), or the second communication device can be part of a communication device (for example, a circuit or a chip responsible for communication functions (such as a Modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core, etc.), or the second communication device can also be a logic module or software capable of implementing all or part of the functions of the communication device. In the method, the second communication device determines first configuration information, the first configuration information being used to configure a first resource of a first data channel; the second communication device transmits the first configuration information; wherein the first resource includes a third resource, the third resource does not include the second resource, and the third resource is used to determine a TBS corresponding to the first data channel.

[0138] Based on the above scheme, the first configuration information sent by the second communication device to the first communication device is used to configure the first resource of the first data channel, and the first communication device transmits or receives the first data channel on the third resource included in the first resource. Wherein, the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, which can improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0139] Optionally, the second communication device can communicate with the first communication device through the first data channel, and correspondingly, the second communication device can transmit or receive the first data channel on the third resource included in the first resource, so that the second communication device and the first communication device can realize the reception or transmission of the first data channel based on the actual transmission of the TBS associated with the third resource, which can improve the transmission performance of the first data channel.

[0147] Based on the manner A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel, i.e., the third resource of the first data channel transmitted by the first communication device does not include the second resource of other time domain positions except the time domain position of the DMRS of the first data channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0148] For example, in the above-mentioned manner A-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR or 5G; for this purpose, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced by the manner A-1.

[0149] For another example, in the above-mentioned manner A-2, A-3 or A-4, the resource pattern of the second resource is the same as the resource pattern of the PDSCH DMRS in NR (or 5G, or 5G NR); for this purpose, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH DMRS on the second resource can be avoided or reduced by the manner A-2, A-3 or A-4.

[0150] For another example, in the above-mentioned manner A-5, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); for this purpose, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced by the manner A-5.

[0151] Optionally, the third resource does not include the DMRS resource of the first data channel, by this manner, the influence and / or interference of the transmission of the first data channel on the DMRS resource of the first data channel can be avoided, so as to improve the data demodulation performance of the first data channel.

[0152] The manner B, the resource pattern of the second resource includes the following manner B-1 and / or manner B-2.

[0154] The manner B-2, the resource pattern of the second resource includes one subcarrier in one frequency domain unit.

[0155] Based on the manner B, the third resource of the first data channel transmitted by the first communication device does not include the second resource of the at least one resource pattern. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0156] For example, in the above-mentioned manner B-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); thus, by the manner B-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0157] For another example, in the above-mentioned manner B-2, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); thus, by the manner B-2, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0203] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" refers to one or more, and "multiple" refers to two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the cases of A alone, A and B together, and B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or multiple items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0204] (5) In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.

[0205] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0206] It can be understood that the information may be processed as necessary between the source and the destination of the information transmission, such as encoding, modulation, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0207] (6) In the embodiments of the present application, "indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by certain information (indication information described below) is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that the indication information can be used to indicate the to-be-indicated information for the sender of the indication information, and the indication information can be used to determine the to-be-indicated information for the receiver of the indication information.

[0208] (7) Rate matching.

[0209] Rate matching is used in wireless communication systems to adjust the coded data bit rate to match the bit carrying capacity of the physical layer transmission resources. In communication systems such as LTE and NR systems, the rate matching process ensures that the number of coded bits matches the number of bits that the physical layer resource units can carry.

[0210] Exemplarily, rate matching involves the following steps:

[0211] ① Encoding: First, the data is channel coded to generate coded bits (CB).

[0212] ② Bit selection: Then, by selecting part of the coded bit stream to match the number of bits that the physical layer resources can carry. This usually involves the insertion or deletion of bits to ensure that the data rate matches the bit carrying capacity of the physical layer resources.

[0213] ③ Interleaving: Interleaving is part of the rate matching process, which changes the output order of the bit stream, but does not involve the addition or deletion of bits.

[0214] The goal of rate matching is to optimize data transmission efficiency, avoid the number of data bits exceeding the carrying capacity of the physical layer resources, and at the same time ensure the reliability and efficiency of transmission.

[0215] Optionally, the time-frequency resources on which data is not mapped can be punctured after the time-frequency resources on which data is mapped.

[0216] Generally, in NR systems, "puncturing" is an implementation of a rate matching technique, mainly used to adjust the rate of the encoded data stream to adapt to different transmission requirements and channel conditions. The process of puncturing involves selectively deleting (or ignoring) part of the bits from the encoded bit stream to reduce the bit rate of the data stream to match the transmission resources of the physical layer. Specifically, when the number of encoded data bits exceeds the number of bits that the RE resources of the physical layer can carry, puncturing is needed to reduce the number of bits. The puncturing algorithm will select which bits to delete according to certain rules, which usually take into account the importance of the bits to minimize the impact on decoding performance.

[0217] In this application, except for special description, the same or similar parts between various embodiments can be mutually referred. In various embodiments of this application, and various implementation manners / implementation methods / realization methods in each embodiment, if there is no special description and logical conflict, the terms and / or descriptions between different embodiments, and between various implementation manners / implementation methods / realization methods in each embodiment are consistent and can be mutually referred, and the technical features in different embodiments, and in various implementation manners / implementation methods / realization methods in each embodiment can be combined to form new embodiments, implementation manners, implementation methods, or realization methods according to their inherent logical relationship. The implementation manners of this application described below do not constitute a limitation on the protection scope of this application.

[0218] In order to facilitate the understanding of the method provided by the embodiments of the present application, the system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is to more clearly illustrate the scheme of the embodiments of the present application, and does not constitute a limitation on the scheme provided by the embodiments of the present application.

[0219] In a possible implementation, the present application can be applied to a Narrow Band-Internet of Things (NB-IoT) system, a Global System for Mobile Communications (GSM) system, an Enhanced Data rate for GSM Evolution (EDGE) system, a Wideband Code Division Multiple Access (WCDMA) system, a Code Division Multiple Access (CDMA2000) system, a Time Division-Synchronization Code Division Multiple Access (TD-SCDMA) system, an integrated sensing and communication (ISAC) communication system, a wireless local area network (WLAN) system, a short-range wireless communication system (such as a sidelink system, a wireless fidelity (Wi-Fi or WiFi) system, a Bluetooth system, or the like), a wired network, a vehicle to everything (V2X) communication system, a device-to-device (D2D) communication system, a vehicle-to-everything (V2X) communication system, a 4th generation (4G) mobile communication system (such as a long term evolution (LTE) system), an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a worldwide interoperability for microwave access (WiMAX) communication system, a 5th generation (5G) mobile communication system (such as a new radio (NR) system), a future evolved new radio (NR) wireless communication system, or another similar communication system, without limitation.For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and future OFDM systems and OFDM-like systems, for example, the present application can be applied to three major application scenarios of the next generation 5G mobile communication system: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and / or enhanced machine type communication (eMTC).

[0220] Referring to FIG. 1a, an architecture diagram of a communication system 10 to which embodiments of the present application are applied is shown. As shown in FIG. 1a, the communication system includes a RAN 100 and a core network 200, and optionally, the communication system 10 can further include an Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1a, collectively referred to as 110), and can further include at least one terminal (e.g., 120a-120j in FIG. 1a, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1a). The terminal 120 is connected to the RAN node 110 in a wireless manner, and the RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network device and the logical functions of the RAN node. Terminals and terminals, and RAN nodes and RAN nodes can be connected to each other in a wired or wireless manner.

[0221] FIG. 1b shows an example diagram of an O-RAN system, which can include other components than those shown in the figure. As shown, an access network device (such as a RAN device, which can be an eNB or a gNB or a next generation access network device) communicates with a core network (CN) through a backhaul and communicates with a UE through an air interface.

[0222] In a possible implementation, the present application can be applied to a long term evolution (LTE) wireless communication system, an NR wireless communication system, and a future evolved NR wireless communication system. For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and a future OFDM system and an OFDM-like system, etc.

[0223] As an example, the RAN node can be a satellite base station or a satellite, which is explained below in connection with FIGS. 1c-1g. FIGS. 1c and 1d are schematic diagrams of a communication system suitable for embodiments of the present application.

[0224] As shown in FIGS. 1c and 1d, the satellite base station provides communication services for terminals. For example, the satellite base station transmits downlink data to a terminal, where the data is encoded using channel coding, and the channel-coded data is transmitted to the terminal after being modulated using constellation modulation. As another example, a terminal transmits uplink data to the satellite base station, where the uplink data can also be encoded using channel coding, and the encoded data is transmitted to the satellite base station after being modulated using constellation modulation. In addition, as shown in FIG. 1d, the satellite base station can also communicate with a ground base station, i.e., the satellite can act as a base station, and also as a terminal.

[0225] In the present application, the satellite can refer to a drone, a hot air balloon, a low earth orbit satellite, a medium earth orbit satellite, a high earth orbit satellite, etc. The satellite can also refer to a non-ground base station or a non-ground device, etc.

[0226] It should be understood that the present application can be applied to a scenario in which a network device communicates with another network device, and the scenario shown in FIG. 1d can also be regarded as an example of network device-to-network device communication, where the satellite and the base station can both be regarded as a network device.

[0227] As an implementation, the present application can be applied to a satellite inter-satellite link communication system. As shown in FIG. 1d, the communication between satellite #1 and satellite #2.

[0228] As shown in FIG. 1e, the satellite inter-satellite link communication system can be divided into two parts: an acquisition pointing tracking (APT) subsystem (including an APT module and an APT transmitter / receiver) and a communication subsystem (including a communication module and a transceiving antenna). Among them, the communication subsystem is mainly responsible for the transmission of inter-satellite information, and the communication subsystem is the main part of the inter-satellite communication system; the APT system is mainly responsible for the acquisition, alignment and tracking between satellites. Among them, the direction of arrival of the incident signal can be determined, which is used for acquisition, and the direction of the transmitted wave is adjusted to aim at the receiving direction, which is used for alignment. In the whole communication process, the APT is constantly adjusted to align and acquire, which is used for tracking. In order to reduce the influence of attenuation and interference in the channel as much as possible, while requiring high confidentiality and transmission rate, the APT must be adjusted in real time to constantly adapt to changes.

[0229] It should be understood that the current APT system is an optical system, which has the disadvantage that optical alignment is difficult and requires mechanical adjustment of the pointing direction. The existing communication subsystem is mostly an optical communication system, and there are also some microwave band systems, mostly using a single high-gain antenna. The existing APT system and communication subsystem are independent systems. The disadvantage is that optical communication is easily affected by vibration and the like, and the rate is unstable; the frequency of millimeter waves is low, the communication capacity is low, and the antenna needs to be mechanically adjusted to point.

[0230] As another implementation manner, the present application can be applied to the scenario of terminal device-to-terminal device communication, for example, an Internet of Things communication system.

[0231] FIG. 1f is a schematic diagram of an Internet of Things wireless screen projection suitable for an embodiment of the present application. A terminal device (for example, a smart phone) establishes a network connection with a television, and the smart phone transmits content that needs to be projected and displayed on the television to the television. After receiving the content transmitted by the smart phone, the television displays the content on its display screen.

[0232] It should be understood that the screen projection scenario shown in FIG. 1f can be regarded as an example of terminal device-to-terminal device communication, in which the smart phone and the television can both be regarded as a terminal device.

[0233] As another implementation manner, the present application can be applied to an integrated access and backhaul (IAB) system.

[0234] FIG. 1g is a schematic diagram of an IAB system applicable to embodiments of the present application. As shown in FIG. 1g, the IAB can include an IAB donor, an IAB node and a terminal. The link between the IAB donor and the IAB node is a backhaul link, and the link between the terminal and the IAB node is an access link. The present application can be applied to both parties in the backhaul link, or both parties in the access link.

[0235] It should be understood that the above system application scenarios are only examples, and the present application can also be applied to other scenarios, which are not listed one by one here.

[0236] In a wireless communication system (for example, the system shown in any one of FIGS. 1a to 1g), the wireless communication resource generally includes time-frequency resources, which will be introduced below taking the NR system as an example. It should be understood that NR can be replaced by 5G or 5G NR.

[0237] 1. Numerology.

[0238] 5G NR introduces the concept of Numerology, which includes sub-carrier spacing (SCS), and corresponding parameters such as symbol length, cycle prefix (CP) length, etc. Since there is a certain mapping relationship between SCS and symbol length, CP length, in some documents, SCS is also often used instead of Numerology.

[0239] For example, the parameters involved in Numerology are shown in Table 2.

[0240] Table 2

[0241] In Table 2, μ represents the sub-carrier spacing index, or μ represents the numerology, the CP length includes the normal (Normal) CP length and the extended (Extended) CP length, and FR represents the frequency range (FR).

[0242] 2. Frame structure.

[0243] In the NR system, the time domain units are symbol, slot, subframe, half frame, frame, etc., wherein the time of one frame is 10 ms, one frame can be divided into 10 subframes numbered 0-9, and the subframes numbered 0-4 form one half frame, and the subframes numbered 5-9 form another half frame. The time of each subframe is 1 ms. Each subframe can include one or more slots, and each slot includes 14 symbols under normal CP and 12 symbols under extended CP.

[0244] For example, the number of slots included in each subframe is related to SCS, and the association is shown in Table 3.

[0245] Table 3

[0246] As shown in the example of FIG. 2a, it is a schematic diagram of the frame structure of 5G NR, including:

[0247] Frame: fixed length of 10 ms, frame number range: 0-1023.

[0248] Subframe: fixed length of 1 ms, subframe number range: 0-9.

[0249] Slot: when normal CP is used, the length is 14 symbols. Since the symbol length is not fixed, the slot length is also not fixed. When the SCS is 60 kHz, extended CP can also be used, and the slot length is 12 symbols. Optionally, the slot is the smallest unit of data scheduling.

[0250] Symbol: the length is not fixed and is related to SCS. Optionally, the symbol is the basic unit of modulation.

[0251] Generally, in the physical layer, one symbol can contain a plurality of sampling points, and the sampling point can be the smallest time unit of the physical layer.

[0252] In addition, the scheduling time unit in the data domain of 5G NR is a slot, and the number of symbols included in the slot is fixed, but the length of the symbol is related to SCS. The following will take SCS of 30 kHz and 120 kHz as examples to illustrate the relationship between frame, subframe, slot and symbol.

[0253] As shown in the examples of FIGS. 2b and 2c, the relationship between frame, subframe, slot and symbol corresponding to SCS of 30 kHz and 120 kHz respectively.

[0254] 3. Symbol type and slot format.

[0255] Generally, OFDM symbols include three types, which are:

[0256] Downlink (DL): denoted by the letter D, used for downlink transmission.

[0257] Uplink (UL): denoted by the letter U, used for uplink transmission.

[0258] Flexible (F): denoted by the letter F, can be used for uplink transmission, also can be used for downlink transmission, and also can be used as guard period (GP) or reserved resource.

[0259] Optionally, each time slot can be freely combined by the three types of symbols, forming a variety of time slot formats.

[0260] As shown in the example of FIG. 2d, according to the time slot format defined by the protocol, the time slot type can be divided into four cases (Cases).

[0261] Case 1: only contains “D” symbols, which is also commonly referred to as a downlink-only slot (DL-only slot).

[0262] Case 2: only contains “U” symbols, which is also commonly referred to as a downlink-only slot (UL-only slot).

[0263] Case 3: only contains “F” symbols, which is also commonly referred to as a flexible-only slot (Flexible-only slot).

[0264] Case 4: a time slot contains at least one “D” or “U” symbol, and there is also an “F” symbol in the time slot.

[0265] In addition, as shown in FIG. 2d, Case 4 can be further divided into several sub-Cases.

[0266] Case 4-1: a time slot contains more “D” symbols and fewer “F” symbols.

[0267] Case 4-2: a time slot contains more “U” symbols and fewer “F” symbols.

[0268] Case 4-3: a time slot contains more “D” symbols, fewer “F” symbols, and fewer “U” symbols.

[0269] Case 4-4: a time slot contains more “U” symbols, fewer “F” symbols, and fewer “D” symbols.

[0270] Case 4-5: a time slot contains alternatingly distributed “D” symbols, “F” symbols, and “U” symbols.

[0271] As can be seen from the above examples, the slot format design of 5G NR can achieve uplink and downlink data changes at the symbol level, while LTE can only achieve changes at the subframe level in general. This design is more flexible, and also makes the slot type more diverse to adapt to different types of services in different scenarios.

[0272] 4. Self-contained slot.

[0273] Case 4-3, Case 4-4 and Case 4-5 in FIG. 2d, also known as self-contained slots, correspond to two structures of self-contained slots, respectively.

[0274] One structure is a downlink-dominant slot (DL-dominant slot): that is, Case 4-3 in FIG. 2d, in which the slot is mainly used for transmission of downlink data, and a small number of symbols are used for transmission of uplink control signals (such as hybrid automatic repeat request (HARQ) feedback of the downlink data) or SRS through time division multiplexing, thereby shortening the downlink HARQ feedback delay.

[0275] Another structure is an uplink-dominant slot (UL-dominant slot): that is, Case 4-4 in FIG. 2d, in which the slot is mainly used for transmission of uplink data, and a small number of symbols are used for transmission of downlink control signals (such as uplink scheduling indication in PDCCH) through time division multiplexing, thereby shortening the uplink scheduling delay.

[0276] Generally, in the design of a self-contained slot, both the network device and the terminal device can switch between uplink and downlink transmission within one slot, and the switching can be guaranteed to work normally by reserving a guard time and not transmitting or receiving any signals in the guard time.

[0277] 5. Mini-slot.

[0278] To further reduce the air interface delay, the protocol proposes the concept of a micro slot, whose time domain length can be less than 14 symbols. Compared with the scheduling of a basic slot, the division in the time domain of a micro slot is more fine-grained, and the scheduling delay is also shorter. The scheduling of a micro slot is usually also referred to as non-slot-based scheduling.

[0279] 6. Frequency domain resources.

[0280] A resource element (RE) is the smallest granularity of physical layer resource in 5G NR, which is 1 subcarrier in frequency domain and 1 OFDM symbol in time domain.

[0281] A resource block (RB) is the basic unit of channel resource allocation in 5G NR in frequency domain, which can contain 12 subcarriers in frequency domain. Since the subcarrier spacing in 5G NR is variable, the actual bandwidth of the RB is also variable.

[0282] A resource grid (RG) is a set of time-frequency resources, which is defined as follows in 5G NR: for different numerologies on each carrier, a RG is a set of resources of all subcarriers in frequency domain and all symbols in time domain with a length of 1 subframe, and the starting point of the frequency domain is in RB granularity. Since different numerologies correspond to different SCS, and a RB is 12 subcarriers, for the same transmission bandwidth, the number of RBs contained in the RG is different under different numerologies. The RG is 1 subframe in time domain. The uplink and downlink each define their own RG.

[0283] As shown in FIG. 2e, it is a schematic diagram of one implementation of resource division of RE, RB and RG. In FIG. 2e, one subframe in time domain can include a plurality of OFDM symbols; one resource element represents a resource of 1 subcarrier in frequency domain and 1 OFDM symbol in time domain; one resource block contains 12 subcarriers in frequency domain; and a resource grid represents a set of time-frequency resources.

[0284] A common resource block (CRB) can be understood as a general term for all RBs in 5G NR, numbered from 0, and the center frequency point of the 0th subcarrier in CRB0 is also Point A.

[0285] A physical resource block (PRB) refers to the RBs contained in the bandwidth part (BWP) of a certain UE in 5G NR, also numbered from 0, which is the basic unit of data channel scheduling.

[0286] Resource Block Group (RBG) refers to the combination of a number of PRBs within a bandwidth part (BWP), also numbered from 0, which is the basic unit of data channel scheduling. An RBG can contain {2, 4, 8, 16} PRBs, the specific number of which is related to the number of RBs in the BWP and the configuration options.

[0287] Resource Element Group (REG) is the basic unit of control channel resources. 1 REG is 12 subcarriers in the frequency domain, i.e. the width of one RB, and 1 OFDM symbol in the time domain. Alternatively, REG can also be replaced by resource unit group.

[0288] Control Channel Element (CCE) is the basic unit of control channel resource scheduling, and 1 CCE is composed of 6 REGs in the frequency domain.

[0289] As shown in Figure 2f, it is a schematic diagram of the relationship between REG and CCE.

[0290] As above is the definition of time-frequency resources of NR, the same definition can be used in future networks, or different definitions can be used. For example, future networks can define multiple subcarrier spacings, not limited to SCS in 5G. One slot can include one or more symbols, one RB can include one or more subcarriers, etc.

[0291] 7. Transmission or reception

[0292] Physical Reception Link Control Channel (PRxCCH): is a physical layer control channel. Generally, the standard protocol is described from the perspective of the terminal device, that is, the physical layer control channel received by the terminal device, which is similar to the PDCCH in LTE and 5G. PRxCCH can be a new physical layer control channel introduced in the next generation communication system (such as 6G). Of course, 6G may still use PDCCH to represent the physical downlink control channel or physical transmission link control channel of the terminal device.

[0293] Physical reception link shared channel (PRxSCH): a kind of physical layer data channel. Generally, the standard protocol is described from the perspective of the terminal device, that is, the physical layer data channel received by the terminal device, which is similar to the PDSCH in LTE and 5G. PRxSCH can be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PDSCH to represent the physical downlink data channel or the physical reception link data channel of the terminal device.

[0294] Physical transmission link control channel (PTxCCH): a kind of physical layer control channel. Generally, the standard protocol is described from the perspective of the terminal device, that is, the physical layer control channel transmitted by the terminal device, which is similar to the PUCCH in LTE and 5G. PTxCCH can be a new physical layer control channel introduced in 6G. Of course, future communications such as 6G may still use PUCCH to represent the physical uplink control channel or the physical transmission link control channel of the terminal device.

[0295] Physical transmission link shared channel (PTxSCH): a kind of physical layer data channel. Generally, the standard protocol is described from the perspective of the terminal device, that is, the physical layer data channel transmitted by the terminal device, which is similar to the PUSCH in LTE and 5G. PTxSCH can be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PUSCH to represent the physical uplink data channel or the physical reception link data channel of the terminal device.

[0296] Optionally, for downlink, it can be described as receiving from the perspective of the terminal device; for uplink, it can be described as transmitting from the perspective of the terminal device.

[0297] At present, in the communication process of different communication devices, the data sender can send data through the data channel, and correspondingly, the data receiver can receive data through the data channel to realize the data transmission process. However, in the above data transmission process, how to improve the data transmission performance is a technical problem to be solved.

[0298] As an example, taking a communication process between a network device and a terminal device as an example, if resources of two or more wireless access technologies conflict, a channel transmission or a signal transmission (denoted as transmission 1) of one wireless access technology can avoid resources of another channel transmission or signal transmission (denoted as transmission 2) of another wireless access technology through resource scheduling, so as to improve transmission performance of the transmission 1. Generally, a channel priority of the transmission 1 is higher than a channel priority of the transmission 2, or a signal priority of the transmission 1 is higher than a signal priority of the transmission 2. For example, the network device can realize active avoidance of PDSCH of LTE from SSB of NR, or active avoidance of PDSCH of NR from cell-specific reference signal (CRS) of LTE, through resource scheduling. Wherein, PDCCH and PDSCH of LTE and NR dynamically share resources on demand. Correspondingly, in the above implementation example, in a case that the transmission 1 is a data channel transmission, the above manner can improve data transmission performance on the data channel.

[0299] However, in the above example, resources occupied by the transmission 1 will completely avoid resources occupied by the transmission 2, which will cause the transmission 2 to be unavailable, and further cause low spectrum efficiency.

[0300] As another example, taking a downlink communication process between a network device and a terminal device as an example, in an NR system, a data channel of the downlink can be PDSCH, and the network device can instruct a certain terminal device (denoted as terminal device 1) to perform rate matching on PDSCH resources for certain specific resources, that is, the specific resources are not used for data transmission. In this way, data transmission of NR PDSCH can be free from interference of the specific resources, and / or signals on the specific resources can be free from interference of PDSCH, so as to improve data transmission performance of NR PDSCH and transmission performance of signals on the specific resources.

[0301] For example, on the PDSCH, different terminal devices (or different users) can transmit respective DMRSs through different DMRS code division multiplexing groups (CDM groups), and generally, DMRSs of different DMRS CDM groups are located in a same symbol. Correspondingly, the above specific resources can include resources occupied by a DMRS code division multiplexing group (CDM group) without data transmission, and the resources are used for transmission of other DMRS CDM groups except for a DMRS CDM group used by the terminal device 1, so as to realize interference avoidance of DMRSs between users of NR multi-user (MU) scheduling through rate matching on the specific resources.

[0302] For example, on PDSCH, the specific resource can include a resource occupied by CRS of LTE, and rate matching of NR CORESET is achieved by rate matching on the specific resource. This method can achieve that the control resource set CORESET is not interfered by PDSCH, and the communication performance of the control channel is guaranteed. This method can also achieve that PDSCH is not interfered by CORESET, and the communication performance of PDSCH is guaranteed.

[0303] For example, on PDSCH, the specific resource can include a resource occupied by CRS of LTE, and rate matching of NR CORESET is achieved by rate matching on the specific resource. This method can achieve that the control resource set CORESET is not interfered by PDSCH, and the communication performance of the control channel is guaranteed. This method can also achieve that PDSCH is not interfered by CORESET, and the communication performance of PDSCH is guaranteed.

[0304] For example, on PDSCH, the specific resource can include a resource occupied by CRS of LTE, and rate matching of NR CORESET is achieved by rate matching on the specific resource. This method can achieve that the control resource set CORESET is not interfered by PDSCH, and the communication performance of the control channel is guaranteed. This method can also achieve that PDSCH is not interfered by CORESET, and the communication performance of PDSCH is guaranteed.

[0305] However, in the above examples, only the rate matching mode of PDSCH of NR is provided, and the use scenario is limited.

[0306] To solve the above problems, the present application provides a communication method and related devices, which will be described in detail below with reference to the accompanying drawings.

[0307] Please refer to FIG. 3, which is an implementation schematic diagram of the communication method provided by the present application. The method includes the following steps.

[0308] It should be understood that, in the following, the method flowchart takes different communication devices (for example, the interaction between the first communication device and the second communication device, the interaction between the third communication device and the fourth communication device, etc.) as an example to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, any communication device (for example, the first communication device, the second communication device, the third communication device or the fourth communication device) can be a communication device, or a chip, a baseband chip, a modem chip, a SoC chip containing a modem core, a SIP chip, a communication module, a chip system, a processor, a logic module or software in the communication device, etc. Optionally, the communication device can be a terminal device or a network device (for example, the network device can be an access network device, an access network element, etc.).

[0309] As an example, in FIG. 3 and / or FIG. 6, the first communication device can be a terminal device and the second communication device can be a network device, or both the first communication device and the second communication device are network devices. For example, the network device can be an access network device, a communication device (e.g., at least one of a CU, a DU, a RU) in an ORAN system.

[0310] As an example, in FIG. 5, the third communication device can be a terminal device and the fourth communication device can be a network device, or both the third communication device and the fourth communication device are network devices. For example, the network device can be an access network device, a communication device (e.g., at least one of a CU, a DU, a RU) in an ORAN system.

[0311] As another example, in FIG. 3 and / or FIG. 6, both the first communication device and the second communication device are terminal devices, i.e., the scheme shown in FIG. 3 and / or FIG. 6 can be applied to a sidelink communication scenario.

[0312] As another example, in FIG. 5, both the third communication device and the fourth communication device are terminal devices, i.e., the scheme shown in FIG. 5 can be applied to a sidelink communication scenario.

[0313] S301. The second communication device sends first configuration information, and correspondingly, the first communication device receives the first configuration information. The first configuration information is used to configure a first resource of a first data channel.

[0314] S302. The second communication device sends second configuration information, and correspondingly, the first communication device receives the second configuration information. The second configuration information is used to configure a second resource.

[0315] S303. The first communication device sends or receives the first data channel on a third resource, wherein the third resource is included in the first resource, and the third resource does not include the second resource.

[0316] Optionally, the first configuration information and the second configuration information can be the same configuration information, or can be different configuration information.

[0317] Optionally, the first configuration information and / or the second configuration information can be physical layer signaling, such as downlink control information (DCI), or can be high layer signaling, such as MAC signaling, or RRC signaling, etc.

[0318] Optionally, steps S301 and S302 can be performed simultaneously, or step S301 can be performed first and then step S302, or step S302 can be performed first and then step S301. The order of steps S301 and S302 is not limited in the present application.

[0319] Optionally, the third resource is included in the first resource, which can be understood as that the third resource is a resource in the first resource, or the third resource is a subset of the first resource, or the third resource includes one or more resource units located in the first resource.

[0320] Optionally, the third resource does not include the second resource, which can be understood as that among one or more resource units included in the third resource, there is at least one resource unit different from one or more resource units included in the second resource; or the one or more resource units included in the third resource are different from the one or more resource units included in the second resource; or the resources in the third resource do not include the resources in the second resource.

[0321] It should be noted that the first communication device transmits or receives the first data channel on the third resource, which can be understood as that the first communication device receives data and / or signals of the first data channel on the third resource, or the first communication device transmits data and / or signals of the first data channel on the third resource.

[0322] As an example, taking the process of receiving the first data channel by the first communication device as an example. In this process, the first communication device can determine the second resource (i.e., the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication device receives data on the first data channel, the first communication device can receive data on the third resource excluding the second resource; in other words, the sending end can rate match data based on the second resource, i.e., the sending end can not transmit data on the second resource, and correspondingly, the first communication device can not receive data on the second resource.

[0323] As another example, taking the process of transmitting the first data channel by the first communication device as an example. In this process, the first communication device can determine the second resource (i.e., the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication device transmits data on the first data channel, the first communication device can transmit data on the third resource excluding the second resource; in other words, the first communication device can rate match data based on the second resource, i.e., the first communication device can not transmit data on the second resource, and correspondingly, the receiving end can not receive data on the second resource.

[0324] From the above process, it can be known that for the transceiver, the second resource can be a time-frequency resource on which data is not mapped.

[0325] For example, for the sending end, the sending end does not map data on the second resource (or determines not to map data on the second resource) through rate matching.

[0326] For example, for the sending end, the sending end can puncture (or delete, ignore, etc.) the bits carried by the second resource after mapping the data on the first resource.

[0327] For example, for the receiving end, the receiving end can receive the data on the third resource which does not include the second resource.

[0328] For example, for the receiving end, the receiving end can ignore (or skip) one or more resource units in the first resource which overlap with the second resource in the process of receiving the data on the first resource.

[0329] Optionally, in the above process, the communication device which communicates with the first communication device on the first data channel can be the communication device (for example, the second communication device) which sends the first configuration information to the first communication device, or can be another communication device, which is not limited here. FIG. 3 and related embodiments only take the second communication device as an example for description.

[0330] Based on the scheme shown in FIG. 3, the first configuration information received by the first communication device in step S301 is used to configure the first resource of the first data channel, and the second configuration information received by the first communication device in step S302 is used to configure the second resource; thereafter, in step S303, the first communication device sends or receives the first data channel on the third resource in the first resource, which does not include the second resource. In this way, the first communication device can implement the transmission of the data channel on the third resource in the first resource except for the specified second resource, and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel and the transmission of other signals on the second resource, so as to improve the data transmission performance.

[0331] In a possible implementation of the method shown in FIG. 3, the first data channel is a data channel of a first radio access technology; and the second resource is used to carry a signal (for example, a reference signal) of a second radio access technology. Specifically, the second resource is used to carry a reference signal of the second radio access technology, and the first data channel on the third resource which does not include the second resource is a data channel of the first radio access technology, so that the above scheme can be applied to a scenario of spectrum sharing of two or more radio access technologies (for example, MRSS), and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel of the first radio access technology and the transmission of the reference signal of the second radio access technology in the scenario, so as to improve the data transmission performance.

[0332] Optionally, the reference signal of the second radio access technology includes at least one of the following: a demodulation reference signal of a data channel, a demodulation reference signal of a broadcast channel, or a phase tracking reference signal of a data channel.

[0333] For example, the reference signal of the second radio access technology can be a PDSCH DMRS, a PBCH DMRS, or a PDSCH PTRS.

[0334] Optionally, the third resource can not include other resources in addition to the second resource configured by the second configuration information. The present application does not limit this.

[0335] For example, the third resource does not include a DMRS CDM group resource used by the first communication device, and the interference avoidance of the DMRS is achieved by rate matching the DMRS CDM group resource.

[0336] The DMRS CDM group (DMRS CDM group) can also be referred to as a CDM group (CDM group).

[0337] For another example, the third resource does not include other DMRS CDM group resources in addition to the DMRS CDM group used by the first communication device, and the interference avoidance of the DMRS between users in MU scheduling in the first radio access technology is achieved by rate matching the other DMRS CDM group resources.

[0338] For another example, the third resource does not include resources occupied by the CRS of LTE, and the rate matching under the coexistence of LTE and the first radio access technology is achieved by rate matching the resources occupied by the CRS of LTE.

[0339] For another example, the third resource does not include RB-symbol level resources, and the rate matching of the CORESET of the first radio access technology is achieved by rate matching the RB-symbol level resources.

[0340] For another example, the third resource does not include ZP CSI-RS resources, and the rate matching of the CSI-RS resources of the first radio access technology is achieved by rate matching the ZP CSI-RS resources.

[0341] For example, the first radio access technology can be a future network, including but not limited to 6G, 5.5G, the next generation network of 5G, etc. The second radio access technology can be NR, 5G, 5G NR, LTE, 4G, etc.

[0342] It should be noted that in the scheme shown in FIG. 3, the second resource can be implemented in various ways, which will be described below in conjunction with some examples.

[0343] In the manner A, the time domain position of the second resource is different from the time domain position (e.g., symbol position, or time slot position, or other time domain position defined in future standard / protocol) of the DMRS of the first data channel; and the resource pattern of the second resource comprises at least one of the following manners A-1 to A-5.

[0344] Manner A-1. The resource pattern of the second resource comprises the 0th subcarrier (e.g., subcarrier 0), the 4th subcarrier (e.g., subcarrier 4), and the 8th subcarrier (e.g., subcarrier 8) in one frequency domain unit.

[0345] Manner A-2. The resource pattern of the second resource comprises the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit.

[0346] Manner A-3. The resource pattern of the second resource comprises the 2nd subcarrier (e.g., subcarrier 2), the 3rd subcarrier (e.g., subcarrier 3), the 8th subcarrier (e.g., subcarrier 8), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit.

[0347] Manner A-4. The resource pattern of the second resource comprises the 4th subcarrier (e.g., subcarrier 4), the 5th subcarrier (e.g., subcarrier 5), the 10th subcarrier (e.g., subcarrier 10), and the 11th subcarrier (e.g., subcarrier 11) in one frequency domain unit.

[0348] Manner A-5. The resource pattern of the second resource comprises one subcarrier (e.g., subcarrier 0, subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 5, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, or subcarrier 11) in one frequency domain unit.

[0349] According to the manner A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel, i.e., the third resource of the first data channel transmitted by the first communication device does not include the second resource in the time domain position other than the time domain position of the DMRS of the first data channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0350] Optionally, the ith subcarrier in the present application can refer to the subcarrier i, or the subcarrier corresponding to the subcarrier number i.

[0351] Optionally, the frequency domain unit can indicate one or more frequency domain resources, including one or more subcarriers, one or more subcarrier groups, one or more resource blocks, one or more physical resource blocks, one or more resource block groups, one or more partial bandwidths, or other implementation manners specified by standards / protocols.

[0352] Optionally, in this application, it is taken as an example that one frequency domain unit includes 12 subcarriers, and similar solutions for a frequency domain unit including other numbers of subcarriers are not described herein.

[0353] Optionally, the resource unit can be the smallest unit of time-frequency resources, and can include one or more time-frequency resources, such as one or more symbols in the time domain and one or more subcarriers in the frequency domain. For example, one resource unit can be a resource of one symbol in the time domain and one subcarrier in the frequency domain. For example, the resource unit can be a resource element (RE), which can be in one or more resource grids (RGs). Alternatively, the resource unit can be other implementation manners specified by standards / protocols.

[0354] Optionally, the time unit can be a frame, a subframe, a slot, a sub-slot, a symbol, a symbol group, etc. The time unit can also be understood as a time domain unit.

[0355] Optionally, the resource pattern can be understood as an RE pattern, a subcarrier pattern, etc.

[0356] In order to facilitate understanding of the above resource patterns, the above resource patterns will be described exemplarily.

[0357] As shown in the example of FIG. 4a, the RBs on each of the one or more symbols share 12 subcarriers, and the indexes of the subcarriers are 0, 1, 2, …, and 11. In FIG. 4a, the PBCH DMRS resource pattern of NR (or 5G, or 5G NR) includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit on one symbol.

[0358] Correspondingly, in the above manner A-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); therefore, by means of A-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0359] As shown in the example of FIG. 4b, the RBs on each of the one or more symbols share 12 subcarriers, and the indexes of the subcarriers are 0, 1, 2, …, and 11.

[0360] In the case that the PDSCH DMRS of NR (or 5G, or 5G NR) corresponds to one CDM group (e.g., 1 CDM group in the figure, such as CDM group #0), the resource pattern includes the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on one symbol.

[0361] In the case that the PDSCH DMRS of NR (or 5G, or 5G NR) corresponds to two CDM groups (e.g., 2 CDM groups in the figure, such as CDM group #0 and CDM group #1), the resource pattern includes the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on one symbol; and the 2nd subcarrier (e.g., subcarrier 2), the 3rd subcarrier (e.g., subcarrier 3), the 8th subcarrier (e.g., subcarrier 8), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the symbol.

[0362] In the case that the PDSCH DMRS of NR (or 5G, or 5G NR) corresponds to three CDM groups (e.g., 3 CDM groups in the figure, such as CDM group #0, CDM group #1, and CDM group #2), the resource pattern includes the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on one symbol; the 2nd subcarrier (e.g., subcarrier 2), the 3rd subcarrier (e.g., subcarrier 3), the 8th subcarrier (e.g., subcarrier 8), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the symbol; and the 4th subcarrier (e.g., subcarrier 4), the 5th subcarrier (e.g., subcarrier 5), the 10th subcarrier (e.g., subcarrier 10), and the 11th subcarrier (e.g., subcarrier 11) in one frequency domain unit on the symbol.

[0363] Correspondingly, in the above-mentioned manner A-2, A-3, or A-4, the resource pattern of the second resource is the same as the resource pattern of the PDSCH DMRS in NR (or 5G, or 5G NR); therefore, by the manner A-2, A-3, or A-4, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH DMRS on the second resource can be avoided or reduced.

[0364] As shown in the example of FIG. 4c, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarriers 0, 1, 2, …, 11. In FIG. 4c, the PDSCH PTRS resource pattern of NR (or 5G, or 5G NR) includes one subcarrier (e.g., the 1stsubcarrier, subcarrier 1) in one frequency domain unit on one symbol. The one subcarrier can be subcarrier 0, subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 5, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, or subcarrier 11, and the example of FIG. 4c illustrates the one subcarrier as subcarrier 1.

[0365] Correspondingly, in the above-described manner A-5, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); therefore, the manner A-5 can avoid or reduce the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource.

[0366] Optionally, the PDSCH PTRS of NR (or 5G, or 5G NR) can be determined by at least one of the following parameters, including: frequency density (the value can be 2 or 4, denoted as K PT-RS ∈{2,4}), time density (the value can be 1 or 2 or 4, denoted as L PT-RS ∈{1,2,4}), or resource element offset.

[0367] Optionally, the RE position of the PDSCH PTRS of NR (or 5G, or 5G NR) in the RB can be determined by at least one of the following parameters, including: radio network temporary identifier (RNTI), the number of RBs for data scheduling, or resourceElementoffset.

[0368] Optionally, the third resource does not include the DMRS resource of the first data channel, and in this way, the influence and / or interference of the transmission of the first data channel on the DMRS resource of the first data channel can be avoided, so as to improve the data demodulation performance of the first data channel.

[0369] The manner B, the resource pattern of the second resource includes the following manner B-1 and / or manner B-2.

[0370] The resource pattern of the second resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit.

[0371] The resource pattern of the second resource includes one subcarrier in one frequency domain unit. The one subcarrier can be subcarrier 0, subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 5, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, or subcarrier 11.

[0372] Based on the manner B, the third resource of the first data channel transmitted by the first communication device does not include the second resource of the at least one resource pattern. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0373] For example, as shown in the example of FIG. 4a, in the manner B-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G or 5G NR). Therefore, by the manner B-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0374] For another example, as shown in the example of FIG. 4c, in the manner B-2, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G or 5G NR). Therefore, by the manner B-2, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0375] In a possible implementation of the method shown in FIG. 3, the second configuration information received by the first communication device in step S302 includes at least one of the following:

[0376] The first information is used to determine the resource pattern of the second resource;

[0377] The second information is used to determine the time domain position of the second resource; or

[0378] The third information is used to determine the frequency domain position of the second resource.

[0379] Thus, the second configuration information used to configure the second resource can include the at least one of the above to achieve the configuration of at least one of the resource pattern, the time domain position, or the frequency domain position of the second resource.

[0380] Optionally, at least one of the resource pattern, the time domain location, or the frequency domain location of the second resource is pre-configured or pre-defined by a protocol to reduce overhead.

[0381] Optionally, in the second configuration information, the first information includes any of the following:

[0382] first indication information indicating a number of code division multiplexing groups, the number of code division multiplexing groups being used to determine a resource pattern of the second resource;

[0383] second indication information indicating that the second resource is used for rate matching, and the resource pattern of the second resource being pre-configured or pre-defined by a protocol;

[0384] third indication information indicating a first index corresponding to the resource pattern of the second resource, the first index being used to indicate one of one or more resource patterns;

[0385] fourth indication information indicating a location of a resource unit included in the second resource in a frequency domain unit, wherein different locations of the resource unit included in the second resource in the frequency domain unit correspond to different resource patterns;

[0386] fifth indication information indicating a second index corresponding to the location of the resource unit included in the second resource in the frequency domain unit, the second index being used to indicate one of one or more locations;

[0387] sixth indication information indicating a ZP CSI-RS resource pattern, wherein the resource pattern of the second resource is the same as the ZP CSI-RS resource pattern; or

[0388] seventh indication information indicating a resource pattern of a RB-symbol level resource used for rate matching, wherein the second resource is a resource in the resource pattern of the RB-symbol level resource.

[0389] Thus, the first information used to determine the resource pattern of the second resource can include at least one of the above to improve flexibility of a scheme implementation.

[0390] Optionally, in the second configuration information, the second information includes any of the following:

[0391] eighth indication information indicating a first bit map, the first bit map being used to indicate an association between a symbol location of the second resource and the first resource or one or more time slots;

[0392] ninth indication information indicating at least one of a starting time unit location, a time unit quantity, or a time domain density of the second resource;

[0393] The tenth indication information is used to indicate a second bit map, and the second bit map is used to indicate an association relationship between a symbol position of the second resource and one or more candidate symbol positions.

[0394] The eleventh indication information is used to indicate a second index corresponding to a starting time unit position of the second resource, and the second index is used to indicate one of one or more starting time unit positions.

[0395] Based on the above scheme, the second information used to determine the time domain position of the second resource can include the above at least one, so as to improve the flexibility of the scheme implementation.

[0396] Optionally, in the above second configuration information, the third information includes any one of the following:

[0397] The twelfth indication information is used to indicate at least one of a starting frequency domain unit position, a terminal frequency domain unit position, a frequency domain unit quantity, and a frequency domain density of the second resource.

[0398] The thirteenth indication information is used to indicate a resource block group (RBG) index to which the second resource belongs.

[0399] The fourteenth indication information is used to indicate a third index corresponding to a starting frequency domain unit position of the second resource, and the third index is used to indicate one of one or more starting frequency domain unit positions.

[0400] The fifteenth indication information is used to indicate a fourth index corresponding to a frequency domain unit quantity of the second resource, and the fourth index is used to indicate one of one or more frequency domain unit quantities.

[0401] Therefore, the second information used to determine the frequency domain position of the second resource can include the above at least one, so as to improve the flexibility of the scheme implementation.

[0402] As can be known from the foregoing description, the resource pattern of the second resource can be implemented in multiple ways, and the various information included in the second configuration information will be described exemplarily in combination with the above multiple implementation manners.

[0403] In at least one of the manner A-2, A-3 or A-4, the various configuration information included in the first information satisfies one or more of the following implementation manners.

[0404] As an implementation example of the first information, the first information can indicate the resource pattern of the second resource in at least one of the following multiple ways.

[0405] As an example, the first information can indicate the resource pattern of the second resource by the number of CDM groups. Optionally, in this example, the first information can be physical layer signaling, such as DCI, or the first information can be high layer signaling, such as RRC signaling or MAC signaling, etc.

[0406] For example, the first information can include the first indication information described above. Wherein, the first indication information can indicate the number of CDM groups by 1 bit or 2 bits or more bits, i.e., the first indication information can indicate that the number of NR PDSCH DMRS CDM groups can be 0, 1, 2, or 3. Optionally, when the number of CDM groups indicated by the first indication information is 0, it means that no rate matching is needed for the NR PDSCH DMRS. When the number of CDM groups indicated by the first indication information is 1, 2, or 3, the resource pattern indicated by the first indication information can refer to the above Fig. 4b and related implementation examples.

[0407] For another example, the first information can include the second indication information described above. Wherein, the number of CDM groups is protocol predefined, such as 0, 1, 2, or 3. Correspondingly, the second indication information can indicate whether to perform rate matching by 1 bit. For example, bit 0 represents no rate matching, and bit 1 represents rate matching, or vice versa.

[0408] For another example, the first information can include the third indication information described above. Wherein, the number of CDM groups can be a candidate value configured by other information (e.g., RRC message / signaling / information, etc.), and the third indication information can indicate whether to perform rate matching or one of the candidate values. For example, if there are s candidate values, the first information can indicate one of the candidate values by bits. Wherein s is a positive integer, represents the ceiling of log2s. For example, if the RRC signaling indicates 2 candidate values, 0 or 2, the first information indicates one of the candidate values by 1 bit. For example, bit 0 represents the first candidate value, and bit 1 represents the second candidate value.

[0409] As another example, the first information can include the third indication information described above. The third indication information can indicate a first index corresponding to the resource pattern of the second resource, and the first index is used to indicate one of one or more resource patterns.

[0410] For example, the resource pattern corresponding to the resource pattern index u1 includes the 0th subcarrier (such as subcarrier 0), the 1st subcarrier (such as subcarrier 1), the 6th subcarrier (such as subcarrier 6), and the 7th subcarrier (such as subcarrier 7) in one frequency domain unit. The third indication information can indicate the resource pattern index u1. For example, the resource pattern index u1 can be the resource pattern corresponding to 1 CDM group #0 in FIG. 4b.

[0411] For example, the resource pattern corresponding to the resource pattern index u2 includes the 2nd subcarrier (such as subcarrier 2), the 3rd subcarrier (such as subcarrier 3), the 8th subcarrier (such as subcarrier 8), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit. The third indication information can indicate the resource pattern index u2. For example, the resource pattern index u2 can be the resource pattern corresponding to 1 CDM group #1 in FIG. 4b.

[0412] For example, the resource pattern corresponding to the resource pattern index u3 includes the 4th subcarrier (such as subcarrier 4), the 5th subcarrier (such as subcarrier 5), the 10th subcarrier (such as subcarrier 10), and the 11th subcarrier (such as subcarrier 11) in one frequency domain unit. The third indication information can indicate the resource pattern index u3. For example, the resource pattern index u3 can be the resource pattern corresponding to 1 CDM group #2 in FIG. 4b.

The third indication information can indicate the resource pattern index u5. For example, the resource pattern index u5 can be the resource pattern corresponding to the 3 CDM groups #0, #1, and #2 in FIG. 4b.

[0415] As another example, the first information can include the fourth indication information described above. The fourth indication information is used to indicate the location of the resource units included in the second resource in the frequency domain unit.

[0416] For example, the fourth indication information is used to indicate that the resource pattern (i.e., the resource pattern corresponding to FIG. 4a) of the second resource includes the 0th subcarrier (e.g., subcarrier 0), the 4th subcarrier (e.g., subcarrier 4), and the 8th subcarrier (e.g., subcarrier 8) in one frequency domain unit.

[0417] For example, the fourth indication information is used to indicate that the resource pattern (i.e., the resource pattern corresponding to the resource pattern index u1 described above) of the second resource includes the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit. The third indication information can indicate the resource pattern index u1.

[0418] For example, the fourth indication information is used to indicate that the resource pattern (i.e., the resource pattern corresponding to the resource pattern index u2 described above) of the second resource includes the 2nd subcarrier (e.g., subcarrier 2), the 3rd subcarrier (e.g., subcarrier 3), the 8th subcarrier (e.g., subcarrier 8), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit. The third indication information can indicate the resource pattern index u2.

[0419] For example, the fourth indication information is used to indicate that the resource pattern (i.e., the resource pattern corresponding to the resource pattern index u3 described above) of the second resource includes the 4th subcarrier (e.g., subcarrier 4), the 5th subcarrier (e.g., subcarrier 5), the 10th subcarrier (e.g., subcarrier 10), and the 11th subcarrier (e.g., subcarrier 11) in one frequency domain unit. The third indication information can indicate the resource pattern index u3.

[0420] For example, the fourth indication information is used to indicate that the resource pattern of the second resource (i.e. the resource pattern corresponding to the resource pattern index u4 described above) includes the 0th subcarrier (such as subcarrier 0), the 1st subcarrier (such as subcarrier 1), the 2nd subcarrier (such as subcarrier 2), the 3rd subcarrier (such as subcarrier 3), the 6th subcarrier (such as subcarrier 6), the 7th subcarrier (such as subcarrier 7), the 8th subcarrier (such as subcarrier 8) and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit. The third indication information can indicate the resource pattern index u4.

[0421] For example, the fourth indication information is used to indicate that the resource pattern of the second resource (i.e. the resource pattern corresponding to the resource pattern index u5 described above) includes the 0th subcarrier (such as subcarrier 0), the 1st subcarrier (such as subcarrier 1), the 2nd subcarrier (such as subcarrier 2), the 3rd subcarrier (such as subcarrier 3), the 4th subcarrier (such as subcarrier 4), the 5th subcarrier (such as subcarrier 5), the 6th subcarrier (such as subcarrier 6), the 7th subcarrier (such as subcarrier 7), the 8th subcarrier (such as subcarrier 8), the 9th subcarrier (such as subcarrier 9), the 10th subcarrier (such as subcarrier 10) and the 11th subcarrier (such as subcarrier 11) in one frequency domain unit. The third indication information can indicate the resource pattern index u5.

[0422] As another example, the first information can include the fifth indication information described above. For example, the fifth indication information can indicate the RE index or the RE position.

[0423] For example, the second communication device indicates the RE index or the RE position (such as RE 0, 1, 6, 7) to the first communication device through RRC signaling or other signaling, and the fifth indication information can indicate the resource pattern through a bit map. For example, 1 RB includes 12 REs, a total of 12 bits, and one bit represents one RE position, such as the bit map 110000110000. The first bit represents RE 0, the second bit represents RE 1, and so on. A bit value of 0 represents that the resource pattern does not include the RE, and a bit value of 1 represents that the resource pattern includes the RE, and vice versa.

[0424] As another example, the first information can include the fifth indication information described above. For example, the fifth indication information can indicate the subcarrier index or the subcarrier position.

[0425] For example, the second communication device indicates the subcarrier indices or the subcarrier positions (e.g., subcarriers 0, 1, 6, 7) to the first communication device through RRC signaling or other signaling, and the fifth indication information can indicate the resource pattern through a bit map. For example, 1 RB includes 12 subcarriers, and a total of 12 bits, one bit representing one subcarrier position, such as a bit map of 110000110000. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.

[0426] As another example, the first information can include the sixth indication information described above. The sixth indication information can indicate the resource pattern of the ZP CSI-RS resource. For example, the sixth indication information can indicate that the resource pattern of the ZP CSI-RS resource is one of the three resource patterns in FIG. 4b.

[0427] For example, the resource pattern of the ZP CSI-RS resource can include subcarriers 0, 1, 6, and 7 in one frequency domain unit, i.e., the resource pattern of the ZP CSI-RS resource can be the resource pattern corresponding to the resource pattern index u1 described above.

[0428] For example, the resource pattern of the ZP CSI-RS resource can include subcarriers 0, 1, 6, and 7 in one frequency domain unit, i.e., the resource pattern of the ZP CSI-RS resource can be the resource pattern corresponding to the resource pattern index u1 described above.

[0429] For example, the resource pattern of the ZP CSI-RS resource can include subcarriers 0, 1, 6, and 7 in one frequency domain unit, i.e., the resource pattern of the ZP CSI-RS resource can be the resource pattern corresponding to the resource pattern index u1 described above.

[0430] As another example, the first information can comprise the seventh indication information described above. For example, the second communication device indicates the rate matching resource to the first communication device through RRC signaling, the configuration information comprises the resource pattern of RB-symbol level, optionally, the RRC signaling can indicate the bit map of frequency domain resource and / or the bit map of time domain resource; accordingly, the first communication device can determine that the pattern of PDSCH DMRS of the second radio access technology needs to be rate matched in the RB-symbol within the pattern based on the RRC signaling. In addition, the RRC can also configure the identification of one or more rate matching resources, and the seventh indication information can be DCI, which activates one or more rate matching resources for dynamic rate matching.

[0431] Optionally, the rate matching resource configured by the RRC signaling described above can be periodic, semi-persistent, or non-periodic resource.

[0432] As an example of the second information, the second information can indicate the time domain position of the second resource through at least one of the following multiple ways.

[0433] Optionally, the PDSCH DMRS of the second radio access technology for rate matching can be on the partial time domain resource of the first data channel of the first radio access technology. In other words, the first communication device can determine that the REs not mapping data can only be on the partial time domain resource of the first data channel of the first radio access technology.

[0434] As shown in the example of FIG. 4d, the time domain resource of the first data channel of the first radio access technology comprises 6 time units (e.g. 6 symbols, symbol indexes are 0, 1, 2, 3, 4 and 5 respectively) in FIG. 4d, and the second resource not mapping data is located on the partial RB resource of the 3rd symbol (e.g. symbol 3), and the specific implementation of the second resource contained in each RB resource can refer to the foregoing FIG. 4b and related description.

[0435] The following will take the second information as DCI as an example for description, such as two-level DCI. The two-level DCI scheme can refer to that the DCI comprises first-level DCI and second-level DCI. For example, the first-level DCI is transmitted in the control channel, and the second-level DCI is transmitted in the data channel, and the second-level DCI can carry more bit information. Generally, the first-level DCI is used to indicate the time-frequency resource, modulation and coding mode and the like of the second-level DCI, and the second-level DCI is used to indicate the scheduling information of the data channel transmission, such as time-frequency resource, modulation and coding mode and the like.

[0436] As an example, the second information can comprise the eighth indication information described above. The eighth indication information can be indicated by the first bit map of the symbol position in the DCI.

[0437] For example, the symbol position can be indicated within a time slot. For example, a time slot includes x1 symbols, the first bitmap can indicate the symbol position by x1 bits. Wherein, x1 is a positive integer. For example, a time slot includes 14 symbols, the first bitmap is 14 bits.

[0438] For example, the symbol position can be indicated on the time domain resource of the first data channel of the first radio access technology. For example, the time domain resource of the first data channel includes x2 symbols, the first bitmap can indicate the symbol position by x2 bits. Wherein, x2 is a positive integer. For example, the first data channel of the first radio access technology only occupies 6 symbols, the first bitmap can be 6 bits.

[0439] As an example, the second information can include the ninth indication information described above. Wherein, the ninth indication information can indicate the starting symbol position and / or the symbol length.

[0440] For example, the starting symbol position indication is indicated within a time slot. For example, a time slot includes x3 symbols, the starting symbol position can be indicated by bits. Wherein, x3 is a positive integer. For example, a time slot includes 14 symbols, 4 bits are needed to indicate the starting symbol position Wherein, represents the upward rounding of log214.

[0441] For example, the starting symbol position can be indicated on the time domain resource of the first data channel of the first radio access technology. For example, the time domain resource of the first data channel includes x4 symbols, the starting symbol position can be indicated by bits. Wherein, x4 is a positive integer, represents the upward rounding of log2x4. For example, the first data channel of the first radio access technology only occupies 6 symbols, 3 bits are needed to indicate the starting symbol position Wherein, represents the upward rounding of log26.

[0442] For example, the symbol length can be a fixed value, such as 1 or 2, etc.

[0443] For example, the starting symbol position can be predefined, such as the starting symbol of a time slot, or the starting symbol of the first data channel of the first radio access technology, etc.

[0444] For example, the symbol length is protocol predefined, or RRC signaling configured. For example, 1 or 2, etc.

[0445] As an example, the second information can comprise the tenth indication information described above. Where the RRC signaling configures the candidate symbol positions, the tenth indication information can indicate the second bit map corresponding to the symbol positions.

[0446] For example, the second communication device indicates the candidate symbol positions, such as 4 positions, to the first communication device through RRC signaling. The tenth indication information can indicate the second bit map, such as 4 bits. For example, the number of bits of the second bit map can be equal to the number of the candidate symbol positions.

[0447] As an example, the second information can comprise the eleventh indication information described above. Where the RRC signaling configures the candidate starting symbol positions, the eleventh indication information can indicate the starting symbol position. For example, the number of bits of the eleventh indication information can be equal to the up-rounded log2(number of the candidate starting symbol positions).

[0448] For example, the second communication device indicates the candidate starting symbol positions, such as 4 positions, to the first communication device through RRC signaling. The eleventh indication information can indicate the starting symbol position, i.e. indicate one position from the 4 positions configured by the RRC signaling, such as through 2 bits of information.

[0449] For another example, the symbol length is pre-defined by the protocol, or configured by the RRC signaling. For example, 1 or 2, etc.

[0450] Optionally, the above-mentioned multiple manners can be combined with each other, or can be implemented individually.

[0451] As an example of the third information, the third information can indicate the frequency domain position of the second resource through at least one of the following multiple manners.

[0452] Optionally, the PDSCH DMRS of the second radio access technology for rate matching can be on the partial frequency domain resource of the first data channel of the first radio access technology. In other words, the first communication device can determine that the REs without mapping data can be only on the partial frequency domain resource of the first data channel of the first radio access technology.

[0453] As shown in the example of FIG. 4d, the symbol of the first data channel of the first radio access technology is 10 RBs in FIG. 4d, and the frequency domain position of the second resource without mapping data is on the higher 4 RBs of the fourth symbol.

[0454] The following will take the third information as DCI as an example for description.

[0455] As an example, the third information can comprise the twelfth indication information described above. Where the twelfth indication information can indicate the starting RB and / or the number of RBs.

[0456] For example, the twelfth indication information can indicate the location of the rate matched frequency domain resource in the frequency domain resource of the first data channel.

[0457] For example, the start frequency domain unit location is the location of the first frequency domain unit in the frequency domain resource of the first data channel, and the end frequency domain unit location is the location of the last frequency domain unit in the frequency domain resource of the first data channel.

[0458] For example, as shown in the example of FIG. 4d, the start frequency domain unit location is the 6th frequency domain unit (e.g., frequency domain unit 6) in the frequency domain resource of the first data channel, the end frequency domain unit location is the 9th frequency domain unit (e.g., frequency domain unit 9) in the frequency domain resource of the first data channel, and the number of frequency domain units is 4, e.g., frequency domain unit 6 to frequency domain unit 9.

[0459] As an example, the third information can include the thirteenth indication information described above. The thirteenth indication information can indicate the index of the RBG. One RBG includes one or more RBs.

[0460] For example, the thirteenth indication information can indicate the location of the rate matched frequency domain resource in the frequency domain resource of the first data channel. For example, if the frequency domain resource of the first data channel includes y1 RBGs, the rate matched frequency domain resource can indicate the index of at least one of the y1 RBGs.

[0461] Optionally, the index of the RBG can be the index of the RBG in the carrier or in the BWP, or the index of the RBG in the frequency domain resource of the first data channel.

[0462] For example, when the index of the RBG is the index of the RBG in the frequency domain resource of the first data channel, if the frequency domain resource of the first data channel includes y1 RBGs, the indicated index of the rate matched RBG can be from 0 to y1-1. For example, the RBG index 0 represents the first RBG of the first data channel, the RBG index 1 represents the second RBG of the first data channel, and so on, and the RBG index y1-1 represents the y1th RBG of the first data channel.

[0463] As an example, the third information can include the fourteenth indication information described above. The RRC signaling configures candidate start RB positions, and the fourteenth indication information can indicate one of the start RB positions.

[0464] For example, the second communication device indicates the candidate start RB positions, e.g., 4 positions, to the first communication device through RRC signaling. The fourteenth indication information indicates the start RB position, i.e., indicates one of the 4 positions configured by RRC signaling, e.g., 2 bits of indication.

[0465] Optionally, the RB length is pre-defined by the protocol, or configured by RRC signaling.

[0466] As an example, the third information can comprise the fifteenth indication information described above. Wherein, the RRC signaling configures candidate RB numbers, and the fifteenth indication information indicates one of the RB numbers.

[0467] For example, the second communication device indicates to the first communication device through RRC signaling that the candidate RB numbers are 4, such as 4 RBs, 8 RBs, 16 RBs, and 32 RBs. Thereafter, the second communication device indicates to the first communication device through the fifteenth indication information that one of the RB numbers, such as one of the 4 RBs configured by the RRC signaling, and the fifteenth indication information can be indicated by 2 bits.

[0468] Optionally, the start RB is pre-defined by the protocol, such as the start RB of the first data channel of the first radio access technology.

[0469] In at least one of the manner A-5 or B-2, the configuration information comprised by the first information satisfies one or more of the following implementation manners.

[0470] As an example of the first information, the first information can indicate the resource pattern of the second resource through at least one of the following manners.

[0471] As an example, the first information can comprise the fourth indication information described above, which can indicate the resource pattern of the PTRS in the RB. Optionally, in this example, the first information can be physical layer signaling, such as DCI, or the first information can be high layer signaling, such as RRC signaling or MAC signaling, etc.

[0472] For example, 1 RB comprises 12 subcarriers, and the fourth indication information can indicate the resource pattern by 4 bits. Wherein, represents the upward rounding of log212.

[0473] As another example, the first information can comprise the fifth indication information described above. For example, the fifth indication information can indicate the RE index or the RE position.

[0474] For example, the second communication device indicates to the first communication device through RRC signaling the RE index or the RE position (such as RE 1). For example, 1 RB comprises 12 REs, and the fifth indication information can indicate the resource pattern by 4 bits. For example, bit 0000 represents RE 0, bit 0001 represents RE 1, and so on, and bit 1100 represents RE 11.

[0475] As another example, the first information can comprise the fifth indication information described above. For example, the fifth indication information can indicate the subcarrier index or the subcarrier position.

[0476] For example, the second communication device indicates the subcarrier index or the subcarrier position (e.g., subcarrier 1) to the first communication device through RRC signaling. For example, 1 RB includes 12 subcarriers, and the fifth indication information can indicate the resource pattern through 4 bits. For example, bit 0000 represents subcarrier 0, bit 0001 represents subcarrier 1, and so on, and bit 1100 represents subcarrier 11.

[0477] As an example, the first information can include the fifth indication information described above. Wherein, the RRC signaling configures candidate RE positions, and the fifth indication information can indicate one of the RE positions. For example, the fifth indication information can indicate the second index of the RE.

[0478] For example, the second communication device indicates 4 candidate RE positions (e.g., RE 0, 1, 6, 7) to the first communication device through RRC signaling, and the fifth indication information can indicate the resource pattern through 2 bits. For example, 00 represents the first candidate position, RE 0; 01 represents the second candidate position, RE 1; 10 represents the third candidate position, RE 6; and 11 represents the fourth candidate position, RE 7.

[0479] As another example, the first information can include the fifth indication information described above. Wherein, the RRC signaling configures candidate subcarrier positions, and the fifth indication information can indicate one of the subcarrier positions. For example, the fifth indication information can indicate the second index of the subcarrier.

[0480] For example, the second communication device indicates 4 candidate subcarrier positions (e.g., subcarrier 0, 1, 6, 7) to the first communication device through RRC signaling, and the fifth indication information can indicate the resource pattern through 2 bits. For example, 00 represents the first candidate position, subcarrier 0; 01 represents the second candidate position, subcarrier 1; 10 represents the third candidate position, subcarrier 6; and 11 represents the fourth candidate position, subcarrier 7.

[0481] As another example, the first information can include the sixth indication information described above. Wherein, the sixth indication information can indicate the resource pattern through the ZP CSI-RS resource.

[0482] For example, 12 subcarriers in 1 RB, and the sixth indication information can indicate values from 0 to 11.

[0483] For example, the resource pattern of the ZP CSI-RS resource can include subcarrier 0, subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 5, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, or subcarrier 11 in one frequency domain unit.

[0484] As another example, the first information can comprise the seventh indication information described above. For example, the second communication device indicates the rate matching resource to the first communication device through RRC signaling, the configuration information comprises the resource pattern of RB-symbol level, optionally, the RRC signaling can indicate the bit map of frequency domain resource and / or the bit map of time domain resource; accordingly, the first communication device can determine that the pattern of the PDSCH PTRS of the second wireless access technology in the RB-symbol within the pattern needs to be rate matched based on the RRC signaling. In addition, the RRC can also configure the identification of one or more rate matching resources, and the seventh indication information can be DCI, which activates one or more rate matching resources for dynamic rate matching.

[0485] Optionally, the rate matching resource configured by the RRC signaling described above can be periodic, semi-persistent, or non-periodic resource.

[0486] As an example of the second information, the second information can indicate the time domain position of the second resource in at least one of the following ways.

[0487] Optionally, the PDSCH PTRS of the second wireless access technology for rate matching can be on part of the time domain resource of the first data channel of the first wireless access technology. In other words, the first communication device can determine that the REs not mapping data can only be on part of the time domain resource of the first data channel of the first wireless access technology.

[0488] As shown in the example of FIG. 4e, the time domain resource of the first data channel of the first wireless access technology comprises 6 time units (e.g. 6 symbols) in FIG. 4d, and the second resource not mapping data is located on part of the RB resource of the 2nd, 3rd, 4th, and 5th symbols (such as symbols 2, 3, 4, and 5), and the specific implementation of the second resource contained in each RB resource can refer to the foregoing FIG. 4c and the related description.

[0489] The following will take the second information as DCI as an example for description, such as two-level DCI. The two-level DCI scheme can refer to that the DCI comprises a first-level DCI and a second-level DCI. The first-level DCI is transmitted in the control channel, and the second-level DCI is transmitted in the data channel, and the second-level DCI can carry more bit information. The first-level DCI is used to indicate the time-frequency resource, modulation and coding mode, and the like of the second-level DCI. The second-level DCI is used to indicate the scheduling information of the data channel transmission, such as the time-frequency resource, modulation and coding mode, and the like.

[0490] As an example, the second information can comprise the eighth indication information described above. The eighth indication information can be indicated by a first bit map of the symbol position in the DCI.

[0491] For example, the symbol position can be indicated within a time slot, one time slot includes z1 symbols, then the first bitmap can indicate the symbol position by z1 bits. Wherein, z1 is a positive integer. For example, one time slot includes 14 symbols, then the first bitmap is 14 bits.

[0492] For example, the symbol position can be indicated within a time slot, one time slot includes z1 symbols, then the first bitmap can indicate the symbol position by z1 bits. Wherein, z1 is a positive integer. For example, one time slot includes 14 symbols, then the first bitmap is 14 bits.

[0493] As an example, the second information can include the ninth indication information described above. Wherein, the ninth indication information can indicate at least one of the starting symbol position, the symbol length, the time domain density.

[0494] Wherein, the time domain density can refer to the density of time unit, such as the time slot density, the symbol density, etc.

[0495] For example, the starting symbol position indication is indicated within a time slot, one time slot includes z3 symbols, then the starting symbol position can be indicated by bits. Wherein, z3 is a positive integer. For example, one time slot includes 14 symbols, then 4 bits are needed to indicate the starting symbol position Wherein, represents the upward rounding of log214.

[0496] For example, the starting symbol position can be indicated within a time slot, one time slot includes z1 symbols, then the first bitmap can indicate the symbol position by z1 bits. Wherein, z1 is a positive integer. For example, one time slot includes 14 symbols, then the first bitmap is 14 bits. bits. Wherein, z4 is a positive integer. For example, the first data channel of the first radio access technology only occupies 6 symbols, then 3 bits are needed to indicate the starting symbol position Wherein, represents the upward rounding of log26.

[0497] For example, the symbol density can be 1, 2, 4. For example, 1 means that there is PTRS in each symbol, 2 means that there is PTRS every 1 symbol, or, there is PTRS in every 2 symbols, 4 means that there is PTRS every 3 symbols, or, there is PTRS in every 4 symbols.

[0498] For example, the symbol length can be a fixed value, for example, 1 or 2, etc.

[0499] For another example, the starting symbol position can be predefined, such as the starting symbol of a slot, or the starting symbol of a first data channel of the first radio access technology, etc.

[0500] For another example, the symbol density is predefined by the protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0501] For another example, the symbol length is predefined by the protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0502] As an example, the second information can comprise the tenth indication information described above. Wherein, the RRC signaling configures candidate symbol positions, the tenth indication information can indicate a second bit map corresponding to the symbol positions.

[0503] For example, the second communication device indicates candidate symbol positions, such as 4 positions, to the first communication device by RRC signaling. The tenth indication information can indicate a second bit map, such as 4 bits. For example, the number of bits of the second bit map can be equal to the number of candidate symbol positions.

[0504] As an example, the second information can comprise the eleventh indication information described above. Wherein, the RRC signaling configures candidate starting symbol positions, the eleventh indication information can indicate a starting symbol position. For example, the number of bits of the eleventh indication information can be equal to the number of candidate starting symbol positions rounded up by log2.

[0505] For example, the second communication device indicates candidate starting symbol positions, such as 4 positions, to the first communication device by RRC signaling. The eleventh indication information can indicate a starting symbol position, i.e. indicates one position from the 4 positions configured by RRC signaling, such as by 2 bits of information.

[0506] For another example, the symbol length is predefined by the protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0507] For another example, the symbol density is predefined by the protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0508] As an example, the second information can comprise other indication information. Wherein, the RRC signaling configures candidate time domain densities, the other indication information can indicate one of the time domain densities.

[0509] For example, the second communication device indicates candidate time domain densities, such as 1 or 2, to the first communication device by RRC signaling. The other indication information can indicate one of the values, such as by 1 bit of information.

[0510] For another example, the symbol length is predefined by the protocol, or configured by RRC signaling.

[0511] For another example, the starting time domain symbol position can be a starting symbol position of the first data channel.

[0512] Optionally, the above-mentioned multiple manners can be combined with each other, or can be implemented individually.

[0513] As an implementation example of the third information, the third information can indicate the frequency domain position of the second resource by at least one of the following multiple manners.

[0514] Optionally, the PDSCH PTRS of the second radio access technology for rate matching can be on the partial frequency domain resources of the first data channel of the first radio access technology. In other words, the first communication device can determine that the REs on which data is not mapped can be only on the partial frequency domain resources of the first data channel of the first radio access technology.

[0515] As shown in the example of FIG. 4e, the symbol of the first data channel of the first radio access technology is 10 RBs in FIG. 4d, and the second resource on which data is not mapped is located on the 6th RB (such as RB 6) of the partial symbol.

[0516] In the following, the third information will be taken as an example of DCI.

[0517] As an example, the third information can include the twelfth indication information described above. The twelfth indication information can indicate at least one of a starting RB position, a frequency domain density, an ending RB position, or a number of RBs.

[0518] For example, the twelfth indication information can indicate the position of the frequency domain resource for rate matching in the frequency domain resource of the first data channel.

[0519] For example, the starting frequency domain unit position is located at a position in the frequency domain resource of the first data channel, and the ending frequency domain unit position is located at a position in the frequency domain resource of the first data channel.

[0520] As shown in the example of FIG. 4e, the starting frequency domain unit position is the 7th frequency domain unit (frequency domain unit 6, numbered from 0) in the frequency domain resource of the first data channel, the ending frequency domain unit position is the 7th frequency domain unit (frequency domain unit 6, numbered from 0) in the frequency domain resource of the first data channel, and the number of frequency domain units is 1 frequency domain unit, such as frequency domain unit 6.

[0521] The frequency domain density can refer to the density of frequency domain units, such as RB density, RBG density, etc.

[0522] For example, the frequency domain density can take values of 2, 4, or other values. For example, 2 means that there is one PTRS in every 2 RBs, or there is a PTRS every 1 RB; 4 means that there is one PTRS in every 4 RBs, or there is a PTRS every 3 RBs.

[0523] As an example, the third information can comprise the thirteenth indication information described in the foregoing. Wherein, the thirteenth indication information can indicate the index of the RBG. Wherein, one RBG comprises one or more RBs.

[0524] For example, the thirteenth indication information can indicate the position of the rate-matched frequency domain resource in the frequency domain resource of the first data channel. For example, the frequency domain resource of the first data channel comprises y1 RBGs, then the rate-matched frequency domain resource can indicate the index of at least one RBG in the y1 RBGs.

[0525] Optionally, the index of the RBG can be the index of the RBG in the carrier or in the BWP, or the index of the RBG in the frequency domain resource of the first data channel.

[0526] For example, when the index of the RBG is the index of the RBG in the frequency domain resource of the first data channel, if the frequency domain resource of the first data channel comprises y1 RBGs, then the indicated index of the rate-matched RBG can be from 0 to y1-1. For example, the RBG index 0 represents the first RBG of the first data channel, the RBG index 1 represents the second RBG of the first data channel, and so on, the RBG index y1-1 represents the y1th RBG of the first data channel.

[0527] As an example, the third information can comprise the fourteenth indication information described in the foregoing. Wherein, the RRC signaling configures candidate starting RB positions, and the fourteenth indication information indicates one of the starting RB positions.

[0528] For example, the second communication device indicates the candidate starting RB positions, such as 4 positions, to the first communication device through RRC signaling. The fourteenth indication information indicates the starting RB position, that is, indicates one from the 4 positions configured by RRC signaling, such as 2 bits of indication.

[0529] Optionally, the RB length is pre-defined by the protocol, or configured by RRC signaling.

[0530] As an example, the third information can comprise the fifteenth indication information described in the foregoing. Wherein, the RRC signaling configures candidate RB numbers, and the fifteenth indication information indicates one of the RB numbers.

[0531] For example, the second communication device indicates the candidate RB numbers to the first communication device through RRC signaling, such as 4 kinds of 4RBs, 8RBs, 16RBs, and 32RBs. Thereafter, the second communication device indicates one of the RB numbers to the first communication device through the fifteenth indication information, such as indicating one from the 4 kinds configured by RRC signaling, and the fifteenth indication information can be indicated by 2 bits.

[0532] Optionally, the starting RB is pre-defined by the protocol, such as the starting RB of the first data channel of the first radio access technology.

[0533] As an example, the third information can comprise the other indication information described above. Wherein, the RRC signaling configures the candidate frequency domain densities, and the other indication information indicates one of the frequency domain densities.

[0534] For example, the second communication device indicates the candidate frequency domain densities to the first communication device through RRC signaling, such as comprising 2, such as 2, 4. The above-mentioned other indication information indicates the frequency domain densities, such as indicating one from the 2 configured by the RRC signaling, such as 1 bit indication.

[0535] Optionally, the RB length is pre-defined by the protocol, or configured by the RRC signaling.

[0536] Optionally, the starting RB is the starting RB of the first data channel.

[0537] In at least one of the manner A-1 or B-1, the configuration information comprised by the first information satisfies one or more of the following implementation manners.

[0538] As an example of the first information, the first information can indicate the resource pattern of the second resource through at least one of the following manners.

[0539] As an example, the first information can indicate the resource pattern of the second resource. Optionally, in this example, the first information can be physical layer signaling, such as DCI, or the first information can be high layer signaling, such as RRC signaling or MAC signaling, etc.

[0540] For example, the first information can comprise the second indication information described above. Wherein, the resource pattern of the second resource can be pre-defined by the protocol, such as the resource pattern of the second resource comprises the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit. Correspondingly, the second indication information can indicate whether to perform rate matching through 1 bit. For example, bit 0 represents not performing rate matching, and bit 1 represents performing rate matching, or vice versa.

[0541] As another example, the first information can comprise the third indication information described above. The third indication information can indicate the first index corresponding to the resource pattern of the second resource, and the first index is used to indicate one of the one or more resource patterns.

[0542] For example, the resource pattern corresponding to the resource pattern index w1 includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit. The third indication information can indicate the resource pattern index w1.

[0543] As another example, the first information can include the fourth indication information described above. The fourth indication information is used to indicate the position of the resource unit included in the second resource in the frequency domain unit.

[0544] For example, the fourth indication information is used to indicate that the resource pattern of the second resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit.

[0545] As another example, the first information can include the fifth indication information described above. For example, the fifth indication information can indicate the RE index or the RE position.

[0546] For example, the second communication device indicates the RE index or the RE position (such as RE 0, 4, and 8) to the first communication device through RRC signaling, and the fifth indication information can indicate the resource pattern through a bit map. For example, 1 RB includes 12 REs, a total of 12 bits, and one bit represents one RE position. For example, the bit map is 100010001000. The first bit represents RE 0, the second bit represents RE 1, and so on. A bit value of 0 represents that the resource pattern does not include the RE, and a bit value of 1 represents that the resource pattern includes the RE, and vice versa.

[0547] As another example, the first information can include the fifth indication information described above. For example, the fifth indication information can indicate the subcarrier index or the subcarrier position.

[0548] For example, the second communication device indicates the subcarrier index or the subcarrier position (such as subcarrier 0, 4, and 8) to the first communication device through RRC signaling, and the fifth indication information can indicate the resource pattern through a bit map. For example, 1 RB includes 12 subcarriers, a total of 12 bits, and one bit represents one subcarrier position. For example, the bit map is 100010001000. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.

[0549] As another example, the first information can comprise the sixth indication information described in the foregoing. Wherein, the sixth indication information can indicate the resource pattern of the ZP CSI-RS resource. For example, the sixth indication information can indicate that the resource pattern of the ZP CSI-RS resource is one of the three resource patterns in FIG. 4b.

[0550] For example, the resource pattern of the ZP CSI-RS resource can comprise subcarriers 0, 4, 8 in one frequency domain unit.

[0551] As another example, the first information can comprise the seventh indication information described in the foregoing. For example, the second communication device can indicate the rate matching resource to the first communication device through RRC signaling, the configuration information comprises the resource pattern of RB-symbol level, optionally, the RRC signaling can indicate the bit map of the frequency domain resource and / or the bit map of the time domain resource; accordingly, the first communication device can determine that the pattern of the PBCH DMRS of the second wireless access technology needs to be rate matched in the RB-symbol within the pattern based on the RRC signaling. In addition, the RRC can also configure the identification of one or more rate matching resources, and the seventh indication information can be DCI, activating one or more rate matching resources for dynamic rate matching.

[0552] Optionally, the rate matching resource configured by the RRC signaling described above can be periodic, semi-persistent, or aperiodic resource.

[0553] As an example of the second information, the second information can indicate the time domain location of the second resource in at least one of the following multiple ways.

[0554] Optionally, the PBCH DMRS of the second wireless access technology for rate matching can be on part of the time domain resource of the first data channel of the first wireless access technology. In other words, the first communication device can determine that the REs not mapping data can only be on part of the time domain resource of the first data channel of the first wireless access technology.

[0555] As shown in the example of FIG. 4f, the time domain resource of the first data channel of the first wireless access technology comprises 2 time units (e.g. 2 symbols) in FIG. 4f, and the second resource not mapping data is located on part of the RB resource of the 1st and 3rd symbols (e.g. symbols 1, 3), and the specific implementation of the second resource contained in each RB resource can refer to the foregoing FIG. 4a and related description.

[0556] The following explanation will use DCI as an example, such as two-level DCI. A two-level DCI scheme can refer to a DCI consisting of a first-level DCI and a second-level DCI. The first-level DCI is transmitted in the control channel, and the second-level DCI is transmitted in the data channel. The second-level DCI can carry more bits of information. The first-level DCI is used to indicate the time-frequency resources, modulation and coding scheme, etc., of the second-level DCI. The second-level DCI is used to indicate the scheduling information for data channel transmission, such as time-frequency resources, modulation and coding scheme, etc.

[0557] As an example, the second information may include the eighth indication information described above. This eighth indication information can be derived from the first bitmap indicating the symbol position in the DCI.

[0558] For example, symbol positions can be indicated within a time slot. If a time slot contains x1 symbols, then the first bitmap can indicate the symbol positions using x1 bits. Here, x1 is a positive integer. For instance, if a time slot contains 14 symbols, then the first bitmap will be 14 bits.

[0559] For example, the symbol position can be indicated on the time-domain resources of the first data channel of the first wireless access technology. If the time-domain resources of the first data channel include x² symbols, then the first bitmap can indicate the symbol position using x² bits. Here, x² is a positive integer. For instance, if the first data channel of the first wireless access technology occupies only 6 symbols, then the first bitmap can be 6 bits.

[0560] As an example, the second information may include the ninth indication information described above. This ninth indication information may indicate the starting symbol position and / or the symbol length.

[0561] For example, the start symbol position indicator is indicated within a time slot, and a time slot includes x3 symbols, which can be achieved through... Each bit indicates the start symbol position. Here, x3 is a positive integer. For example, if one time slot contains 14 symbols, then indicating the start symbol position requires 4 bits. in, This indicates rounding up from log214.

[0562] For example, the starting symbol position can be indicated on the time-domain resources of the first data channel of the first radio access technology. If the time-domain resources of the first data channel include x4 symbols, then it can be indicated by... Each bit indicates the start symbol position. Here, x4 is a positive integer. For example, if the first data channel of the first radio access technology occupies only 6 symbols, then 3 bits are needed to indicate the start symbol position. in, This indicates rounding up from log26.

[0563] For example, the symbol length can be a fixed value, such as 1 or 2, etc.

[0564] For example, the starting symbol position can be predefined, such as the starting symbol of a slot, or the starting symbol of a first data channel of a first radio access technology, etc.

[0565] For example, the symbol position can include the starting symbol position, and a second symbol position after the starting symbol position. For example, if the starting symbol position is indicated as s0, the symbol position of the second resource is s0 and s0+2.

[0566] For example, the symbol length is predefined by a protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0567] As an example, the second information can include the tenth indication information described above. Wherein, the RRC signaling configures candidate symbol positions, and the tenth indication information can indicate a second bit map corresponding to the symbol positions.

[0568] For example, the second communication device indicates candidate symbol positions, such as 4 positions, to the first communication device by RRC signaling. The tenth indication information can indicate a second bit map, such as 4 bits. For example, the number of bits of the second bit map can be equal to the number of candidate symbol positions.

[0569] As an example, the second information can include the eleventh indication information described above. Wherein, the RRC signaling configures candidate starting symbol positions, and the eleventh indication information can indicate a starting symbol position. For example, the number of bits of the eleventh indication information can be equal to the up-round of log2(number of candidate starting symbol positions).

[0570] For example, the second communication device indicates candidate starting symbol positions, such as 4 positions, to the first communication device by RRC signaling. The eleventh indication information can indicate a starting symbol position, i.e., indicates a position from the 4 positions configured by RRC signaling, such as by 2-bit information.

[0571] For example, the symbol length is predefined by a protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0572] Optionally, the above-mentioned multiple manners can be combined with each other, or can be implemented individually.

[0573] As an example of the third information, the third information can indicate the frequency domain position of the second resource by at least one of the following multiple manners.

[0574] Optionally, the PBCH DMRS of the second radio access technology for rate matching can be on the part of the frequency domain resources of the first data channel of the first radio access technology. In other words, the first communication device can determine that the REs not mapping data can be only on the part of the frequency domain resources of the first data channel of the first radio access technology.

[0575] As shown in the example of FIG. 4f, the first data channel of the first radio access technology has 10 RBs in FIG. 4f, and the second resource not mapping data is located on the higher 4 RBs of the frequency domain position of the fourth symbol.

[0576] In the following, the third information will be taken as an example of DCI.

[0577] As an example, the third information can include the twelfth indication information described above. The twelfth indication information can indicate the starting RB and / or the number of RBs.

[0578] For example, the twelfth indication information can indicate the position of the frequency domain resource for rate matching in the frequency domain resource of the first data channel.

[0579] For example, the starting frequency domain unit position is in the position of the frequency domain resource of the first data channel, and the ending frequency domain unit position is in the position of the frequency domain resource of the first data channel.

[0580] As shown in the example of FIG. 4d, the starting frequency domain unit position is the 6th frequency domain unit (frequency domain unit 6, numbered from 0) in the frequency domain resource of the first data channel; the ending frequency domain unit position is the 9th frequency domain unit (frequency domain unit 9, numbered from 0) in the frequency domain resource of the first data channel; and the number of frequency domain units is 4, such as frequency domain unit 6 to frequency domain unit 9.

[0581] As an example, the third information can include the thirteenth indication information described above. The thirteenth indication information can indicate the index of the RBG. One RBG includes one or more RBs.

[0582] For example, the thirteenth indication information can indicate the position of the frequency domain resource for rate matching in the frequency domain resource of the first data channel. For example, the frequency domain resource of the first data channel includes y1 RBGs, and the frequency domain resource for rate matching can indicate the index of at least one RBG of the y1 RBGs.

[0583] Optionally, the index of the RBG can be the index of the RBG in the carrier or in the BWP, or the index of the RBG in the frequency domain resource of the first data channel.

[0584] For example, when the index of the RBG is the RBG index of the frequency domain resource of the first data channel, if the frequency domain resource of the first data channel includes y1 RBGs, the indicated RBG index for rate matching can be from 0 to y1-1. For example, RBG index 0 represents the first RBG of the first data channel, RBG index 1 represents the second RBG of the first data channel, and so on, and RBG index y1-1 represents the y1th RBG of the first data channel.

[0585] As an example, the third information can include the fourteenth indication information described above. Wherein, the RRC signaling configures candidate starting RB positions, and the fourteenth indication information indicates one of the starting RB positions.

[0586] For example, the second communication device indicates to the first communication device through RRC signaling candidate starting RB positions, such as 4 positions. The fourteenth indication information indicates a starting RB position, that is, indicates one from the 4 positions configured by RRC signaling, such as 2 bits of indication.

[0587] Optionally, the RB length is pre-defined by the protocol, or configured by RRC signaling.

[0588] As an example, the third information can include the fifteenth indication information described above. Wherein, the RRC signaling configures candidate RB numbers, and the fifteenth indication information indicates one of the RB numbers.

[0589] For example, the second communication device indicates to the first communication device through RRC signaling that the candidate RB numbers are 4 kinds, such as 4 RBs, 8 RBs, 16 RBs, and 32 RBs. Thereafter, the second communication device indicates to the first communication device through the fifteenth indication information one of the RB numbers, such as indicating one from the 4 kinds configured by RRC signaling, and the fifteenth indication information can be indicated by 2 bits.

[0590] Optionally, the starting RB is pre-defined by the protocol, such as the starting RB of the first data channel of the first radio access technology.

[0591] The above provides some example introduction to the implementation process of mode A-1, mode A-2, mode A-3, mode A-4, mode A-5, mode B-1 and mode B-2. As known from the foregoing, the second resource can be implemented in multiple ways, for example, the second resource can be implemented in at least one of mode A-1, mode A-2, mode A-3, mode A-4, mode A-5, mode B-1 or mode B-2, and the specific implementation process of the at least one mode can refer to the above provided some examples, and the corresponding technical effects are achieved.

[0592] In a possible implementation of the method shown in FIG. 3, the method further includes that the first communication device receives third configuration information, the third configuration information being used to indicate at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel. Specifically, the first communication device can further receive the third configuration information, so that the first communication device can determine at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel through the third configuration information, so as to receive the DMRS on the first data channel based on the at least one, and demodulate / parse the data carried on the first data channel based on the received DMRS.

[0593] Optionally, the first configuration information and the third configuration information can be the same configuration information, or can be different configuration information.

[0594] Optionally, the first configuration information and / or the third configuration information can be physical layer signaling such as DCI, or can be high layer signaling such as MAC signaling, or RRC signaling, etc.

[0595] In a possible implementation, the carrier where the first data channel is located is used to determine at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel. Specifically, the DMRS of the first data channel can be used to demodulate / parse the data carried on the first data channel, and the carrier where the first data channel is located can be used to determine at least one of resource pattern information, code division multiplexing group information, sequence information of the DMRS of the first data channel. In this way, different carriers can have different DMRS configurations, and therefore the first communication device can implement the reception or transmission of the DMRS based on the DMRS configuration corresponding to the carrier where the data channel is located, so as to improve the reception / parse success rate of the DMRS by the receiving side of the DMRS, and further improve the data reception performance.

[0596] Optionally, the carrier where the first data channel is located can also be described as a communication carrier where the first data channel is located.

[0597] As an example, in the case where the carrier where the first data channel is located is a communication carrier (for example, a shared carrier) of the first radio access technology and the second radio access technology, the communication device (for example, the first communication device, the second communication device, the third communication device described hereinafter, etc.) can determine that the communication carrier is used for communication of the first radio access technology and the second radio access technology at the same time. In this case, the communication device can determine at least one of the following:

[0598] The resource pattern information of the reference signal of the first radio access technology is the same as the resource pattern information of the reference signal of the second radio access technology; or, the code division multiplexing group information of the reference signal of the first radio access technology is the same as the code division multiplexing group information of the reference signal of the second radio access technology; or, the sequence information of the reference signal of the first radio access technology is the same as the sequence information of the reference signal of the second radio access technology.

[0599] In this way, on the shared carrier, different radio access technologies can use partially same or totally same reference signal configurations, and implementation complexity can be reduced.

[0600] As another example, in the case that the carrier where the first data channel is located is a communication carrier (e.g., a dedicated communication carrier) of the first radio access technology, the communication device (e.g., the first communication device, the second communication device, the third communication device described hereinafter, etc.) can determine that the communication carrier is not used for communication of the second radio access technology. In this case, the communication device can determine at least one of the following:

[0601] The resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology; or, the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology; or, the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology.

[0602] In this way, on the dedicated carrier, different radio access technologies can use partially different or totally different reference signal configurations, the flexibility of the scheme implementation can be improved, and the interference between reference signals of different radio access technologies can be reduced to improve the communication performance.

[0603] Optionally, the third configuration information described above and the carrier where the first data channel is located can be used to jointly determine at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel. For example, the carrier where the first data channel is located is used to determine at least one of one or more resource pattern information, one or more code division multiplexing group information, and one or more sequence information of the DMRS of the first data channel, and the third configuration information is used to indicate at least one of the one or more resource pattern information, the one or more code division multiplexing group information, or the one or more sequence information.

[0604] Optionally, the resource pattern information of the reference signal (i.e., the reference signal on the first data channel, such as the DMRS) of the first radio access technology can be implemented in various ways.

[0605] As an example, the resource pattern information of the reference signal of the first radio access technology is same as the resource pattern information of the reference signal of the second radio access technology; wherein the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology, and / or the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be same, so that the reference signals of different radio access technologies can be distinguished by different code division multiplexing groups and / or different sequences (e.g. orthogonal sequences), to save resource overhead.

[0606] As another example, the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be different, so that the reference signals of different radio access technologies can be distinguished by different resource patterns, to reduce implementation complexity.

[0607] For example, the third configuration information can indicate the resource pattern information of the reference signal of the first radio access technology by 1 bit.

[0608] For example, when the value of the 1 bit is "1", it indicates that the resource pattern information of the reference signal of the first radio access technology is same as the resource pattern information of the reference signal of the second radio access technology; and when the value of the 1 bit is "0", it indicates that the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology.

[0609] For example, when the value of the 1 bit is "0", it indicates that the resource pattern information of the reference signal of the first radio access technology is same as the resource pattern information of the reference signal of the second radio access technology; and when the value of the 1 bit is "1", it indicates that the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology.

[0610] Similarly, the third configuration information can indicate the code division multiplexing group information of the reference signal of the first radio access technology by 1 bit.

[0611] For example, when the 1-bit is "1", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is the same as the code division multiplexing group information of the reference signal of the second radio access technology; and when the 1-bit is "0", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology.

[0612] For example, when the 1-bit is "1", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is the same as the code division multiplexing group information of the reference signal of the second radio access technology; and when the 1-bit is "0", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology.

[0613] Similarly, the third configuration information can indicate the sequence information of the reference signal of the first radio access technology by 1-bit.

[0614] For example, when the 1-bit is "1", it indicates that the sequence information of the reference signal of the first radio access technology is the same as the sequence information of the reference signal of the second radio access technology; and when the 1-bit is "0", it indicates that the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology.

[0615] For example, when the 1-bit is "1", it indicates that the sequence information of the reference signal of the first radio access technology is the same as the sequence information of the reference signal of the second radio access technology; and when the 1-bit is "0", it indicates that the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology.

[0616] As an example, taking the first radio access technology as 6G and the first data channel as 6G PDSCH (denoted as 6G PDSCH), and the second radio access technology as 5G as an example, the above implementation is exemplarily described in combination with some implementation examples.

[0617] For example, two patterns can be designed for 6G PDSCH DMRS, one pattern (such as pattern A) is used for 5G-6G shared carrier, such as adopting the design of 5G PDSCH DMRS, which can realize the spatial division multiplexing of 5G UE and 6G UE, the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and different CDM groups are adopted, and one pattern (such as pattern B) is used for 6G dedicated spectrum, such as sparse pilot, etc.

[0618] For example, two DMRS CDM groups can be designed for 6G PDSCH DMRS, one DMRS CDM group (such as CDM group A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS CDM group, which can realize spatial division multiplexing of 5G UE and 6G UE, and the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and different CDM groups are used, and one DMRS CDM group (such as CDM group B) is used for 6G dedicated spectrum, such as 6G CDM group, etc.

[0619] For example, two DMRS sequences can be designed for 6G PDSCH DMRS, one DMRS sequence (such as DMRS sequence A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS sequence, which can realize spatial division multiplexing of 5G UE and 6G UE, and the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and one DMRS sequence (such as DMRS sequence B) is used for 6G dedicated spectrum, such as 6G DMRS sequence, etc.

[0620] In the above examples, the third configuration information can be used to indicate the related information of the 6G PDSCH DMRS, so that the first communication device determines the related information of the 6G PDSCH DMRS according to the third configuration information.

[0621] For example, the related information of the 6G PDSCH DMRS can include at least one of the pattern information of the 6G DMRS, the information of the 6G DMRS CDM group, and the information of the 6G DMRS sequence.

[0622] For example, the related information of the 6G PDSCH DMRS can be whether to use the related design of 5G DMRS.

[0623] Optionally, the third configuration information can be DCI, and 1 bit in the DCI can be used to indicate the related information of the 6G PDSCH DMRS. For example, bit 0 represents pattern A, and bit 1 represents pattern B.

[0624] For example, bit 0 represents DMRS CDM group A, and bit 1 represents DMRS CDM group A.

[0625] For example, bit 0 represents DMRS sequence A, and bit 1 represents DMRS sequence B.

[0626] In a possible implementation of the method shown in FIG. 3, the method further includes that the first communication device receives fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource. Specifically, the first communication device can further receive the fourth configuration information, so that the first communication device can determine, through the fourth configuration information, that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, so as to enable the first communication device to implement the receiving or transmitting of the first data channel based on the TBS associated with the third resource, improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0627] Alternatively, the TBS corresponding to the first data channel is determined based on the third resource. Specifically, the first communication device can determine, through pre-configuration or in a protocol pre-defined manner, that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, so as to enable the first communication device to implement the receiving or transmitting of the first data channel based on the TBS associated with the third resource, and improve the receiving performance of the receiver.

[0628] For example, taking the PDSCH of NR as an example, the process in which the communication device (such as the first communication device, the second communication device, the third communication device described hereinafter, etc.) determines the TBS of the data channel can include:

[0629] Step 1: The communication device determines the number of REs of the PDSCH allocated in one RB, denoted as N' RE .

[0630] For example, satisfies:

[0631] wherein, denotes the number of subcarriers of one RB in the frequency domain, denotes the number of OFDM symbols scheduled in one slot, denotes the number of REs of DMRS in one PRB within the scheduling duration, including the overhead of the DMRS CDM group indicated in the DCI. is the overhead value configured through a high-layer parameter (such as a parameter indicating the overhead, Xoh-PDSCH), for example, the overhead value can be 0, 6, 12, or 18. If the high-layer parameter Xoh-PDSCH is not configured, the value of Xoh-PDSCH is 0.

[0632] Step 2: The communication device determines the number of available REs N RE based on N' RE .

[0633] Exemplarily, N RE satisfies:

[0634] N RE = min(156, N' RE )*n PRB ;

[0635] wherein n PRB represents the total number of allocated PRBs corresponding to the communication device, and min(156, N' RE ) represents the minimum value between 156 and N' RE .

[0636] Optionally, N RE satisfies: N RE = N RE *n PRB .

[0637] Step 3, the communication device determines the temporary number of information bits N RE based on N info .

[0638] Exemplarily, N info satisfies: N info = N RE *R*Q m *v;

[0639] wherein R represents the code rate (for example, determined by a modulation and coding scheme (MCS)), Q m represents the adjustment mode, and v represents the number of layers (for example, determined by the number of layers indication information in the DCI, or predefined, such as 1 layer).

[0640] Step 4, the communication device determines the TBS based on N info .

[0641] For example, in the case of N info ≤ 3824, the communication device can determine the TBS based on a preconfigured or protocol predefined table.

[0642] For another example, in the case of N info > 3824, the communication device can quantize the TBS by 8. For example, after the communication device cuts the TBS into coding blocks, if the number of coding blocks cut according to the size of the coding blocks is C, then the final TBS needs to be a multiple of C*8. (If the code rate is less than 1 / 4, the size of the coding block is 3840 (with 24 bits of redundancy check code), otherwise the size of the coding block is 8448 (with 24 bits of redundancy check code)).

[0643] As can be seen from the implementation process of steps 1 to 4, the determination process of TBS takes into account the overhead of DMRS of the first data channel (e.g., parameters). ) and the overhead of high-level configurations (e.g. However, as described above, the resource for the first communication device to receive or transmit the first data channel is a third resource, which does not include the second resource. Therefore, determining the TBS based on the above steps 1 to 4 will lead to inaccurate TBS calculation, thereby affecting data transmission performance.

[0644] In the above technical solution, the TBS corresponding to the first data channel is determined based on the third resource. That is, the determination of the TBS takes into account the third resource that does not include the second resource, so the determination process of the TBS also involves the overhead of the second resource (such as in step 1 above). Replace with: N″ RE (This indicates the number of REs occupied by the second resource), which can improve the accuracy of TBS calculation, thereby improving data transmission performance and thus improving communication performance.

[0645] Please refer to Figure 5, which is a schematic diagram of another implementation of the communication method provided in this application. The method includes the following steps.

[0646] S501. The third communication device determines a carrier for communication, the carrier for communication being used to determine fourth information of a reference signal, the fourth information including at least one of one or more resource pattern information, one or more code division multiplexing group information, and one or more sequence information.

[0647] S502. The third communication device sends or receives reference signals based on the fourth information.

[0648] Based on the scheme shown in Figure 5, the communication carrier can be used to determine at least one of the following: resource pattern information, code division multiplexing group information, and sequence information of the reference signal. In this way, the third communication device can receive or transmit the reference signal based on the reference signal configuration corresponding to the communication carrier, thereby improving the success rate of the receiver / parsing of the reference signal and thus improving communication performance.

[0649] Optionally, the reference signal may include one or more of the following: DMRS (e.g., PDSCH DMRS, PBCH DMRS, or PDCCH DMRS), PTRS, synchronization signal / physical broadcast channel block (SSB or S-SS / PSBCH block), CSI-RS, TRS, and SRS.

[0650] Optionally, the resource pattern information of the reference signal for the first wireless access technology can be implemented in a variety of ways.

[0651] As an example, the resource pattern information of the reference signal of the first radio access technology is the same as the resource pattern information of the reference signal of the second radio access technology; wherein the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology, and / or the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be the same, so that the reference signals of different radio access technologies can be distinguished by different code division multiplexing groups and / or different sequences (such as orthogonal sequences), so as to save resource overhead.

[0652] As another example, the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be different, so that the reference signals of different radio access technologies can be distinguished by different resource patterns, so as to reduce the implementation complexity.

[0653] As an example, taking the first radio access technology as 6G and the first data channel as 6G PDSCH (denoted as 6G PDSCH), and the second radio access technology as 5G as an example, the above implementation is exemplarily described in combination with some implementation examples.

[0654] For example, two patterns can be designed for 6G PDSCH DMRS, one pattern (such as pattern A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS, which can realize the spatial division multiplexing of 5G UE and 6G UE, the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and different CDM groups are used, and one pattern (such as pattern B) is used for 6G dedicated spectrum, such as sparse pilot, etc.

[0655] For example, two DMRS CDM groups can be designed for 6G PDSCH DMRS, one DMRS CDM group (such as CDM group A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS CDM group, which can realize the spatial division multiplexing of 5G UE and 6G UE, the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and different CDM groups are used, and one DMRS CDM group (such as CDM group B) is used for 6G dedicated spectrum, such as 6G CDM group, etc.

[0656] For example, two DMRS sequences can be designed for 6G PDSCH DMRS, one DMRS sequence (such as DMRS sequence A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS sequence, which can realize spatial division multiplexing of 5G UE and 6G UE, and the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and one DMRS sequence (such as DMRS sequence B) is used for 6G dedicated spectrum, such as 6G DMRS sequence, etc.

[0657] In the above examples, the third configuration information can be used to indicate the related information of the 6G PDSCH DMRS, so that the first communication device determines the related information of the 6G PDSCH DMRS according to the third configuration information.

[0658] For example, the related information of the 6G PDSCH DMRS can include at least one of the pattern information of the 6G DMRS, the information of the 6G DMRS CDM group, and the information of the 6G DMRS sequence.

[0659] For example, the related information of the 6G PDSCH DMRS can be whether to use the related design of the 5G DMRS.

[0660] Optionally, the third configuration information can be DCI, and the related information of the 6G PDSCH DMRS can be indicated by 1 bit in the DCI.

[0661] For example, bit 0 represents pattern A, and bit 1 represents pattern B.

[0662] For example, bit 0 represents DMRS CDM group A, and bit 1 represents DMRS CDM group A.

[0663] For example, bit 0 represents DMRS sequence A, and bit 1 represents DMRS sequence B.

[0664] In a possible implementation, the carrier used for the communication is used for communication of at least two radio access technologies. In this way, the above scheme can be applied to a scenario of two or more radio access technology spectrum sharing (such as MRSS), and the same reference signal configuration is used for different radio access technologies in the scenario, which can improve the communication performance while reducing the implementation complexity.

[0665] In a possible implementation, the carrier for the communication is used for communication of one radio access technology. In this way, different carriers can have different reference signal configurations, and the third communication device can implement the reception or transmission of the reference signal based on the corresponding reference signal configuration of the carrier for the communication of the one radio access technology, which can improve the communication performance and also enable the reception or transmission of the reference signal of different radio access technologies based on different reference signal configurations, thereby improving the transmission performance of the reference signal.

[0666] In a possible implementation, the method further includes: the third communication device receiving or transmitting fifth configuration information, the fifth configuration information being used to indicate at least one of the following: one of the one or more resource pattern information, one of the one or more code division multiplexing group information, or one of the one or more sequence information. Specifically, the third communication device can further receive or transmit the fifth configuration information, so that the receiver of the fifth configuration information can determine the at least one based on the fifth configuration information, and can implement flexible configuration of at least one of the resource pattern, the code division multiplexing group, and the sequence through the fifth configuration information, thereby improving the flexibility of the scheme implementation.

[0667] Optionally, the implementation of the fifth configuration information can refer to the implementation process of the third configuration information described above.

[0668] It should be noted that in the method shown in FIG. 5, the implementation process of each step can refer to the description of FIG. 3 and related embodiments described above, and the corresponding technical effects are achieved, which will not be repeated here.

[0669] Please refer to FIG. 6, which is another implementation schematic diagram of the communication method provided by the present application, and the method includes the following steps.

[0670] S601. The second communication device transmits first configuration information, and the first communication device receives the first configuration information. The first configuration information is used to configure a first resource of a first data channel.

[0671] S602. The first communication device determines the TBS of the first data channel based on a third resource, the third resource being included in the first resource, and the third resource not including a second resource.

[0672] Optionally, the first communication device can communicate with another communication device through the first data channel, and correspondingly, in the method shown in FIG. 6, the other communication device determines the TBS of the first data channel based on the third resource.

[0673] For example, the other communication device is the second communication device, and correspondingly, after the second communication device determines the TBS of the first data channel based on the third resource, the second communication device communicates with the first communication device based on the TBS.

[0674] For example, the other communication device is different from the second communication device, and the other communication device can determine the TBS of the first data channel based on the third resource in a protocol predefined manner, a preconfigured manner, or a manner configured or indicated by the second communication device, and perform communication with the first communication device based on the TBS.

[0675] Based on the scheme shown in FIG. 6, the first configuration information received by the first communication device in step S601 is used to configure the first resource of the first data channel, and the first communication device can determine the TBS of the first data channel based on the third resource in step S602. The TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, which can improve the accuracy of TBS calculation and further improve the transmission performance of the first data channel.

[0676] Optionally, after step S602, the first communication device can send or receive the first data channel on the third resource included in the first resource, so that the first communication device can perform reception or sending of the first data channel based on the TBS associated with the actually transmitted third resource, which can improve the transmission performance of the first data channel.

[0677] Optionally, any communication device (for example, the first communication device or the other communication device described above) determines the TBS of the first data channel based on the third resource, which can be understood as: the third resource is used to determine the TBS of the first data channel, or the TBS of the first data channel is determined based on the third resource.

[0678] Optionally, the TBS corresponding to the first data channel can also be referred to as the TBS of the first data channel.

[0679] It should be noted that the second resource can be implemented in various ways, which will be described below in conjunction with some examples.

[0680] Option A, the time domain position of the second resource is different from the time domain position of the DMRS of the first data channel, and the resource pattern of the second resource includes at least one of the following options A-1 to A-5.

[0681] Option A-1. The resource pattern of the second resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit.

[0682] Option A-2. The resource pattern of the second resource includes the 0th subcarrier (such as subcarrier 0), the 1st subcarrier (such as subcarrier 1), the 6th subcarrier (such as subcarrier 6), and the 7th subcarrier (such as subcarrier 7) in one frequency domain unit.

[0683] Manner A-3. The resource pattern of the second resource comprises the 2nd subcarrier (such as subcarrier 2), the 3rd subcarrier (such as subcarrier 3), the 8th subcarrier (such as subcarrier 8) and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit.

[0684] Manner A-4. The resource pattern of the second resource comprises the 4th subcarrier (such as subcarrier 4), the 5th subcarrier (such as subcarrier 5), the 10th subcarrier (such as subcarrier 10) and the 11th subcarrier (such as subcarrier 11) in one frequency domain unit.

[0685] Manner A-5. The resource pattern of the second resource comprises one subcarrier (such as subcarrier 0, subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 5, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, or, subcarrier 11) in one frequency domain unit.

[0686] Based on the manner A, the time domain location of the second resource is different from the time domain location of the DMRS of the first data channel, i.e., the third resource of the first data channel transmitted by the first communication device does not comprise the second resource in the time domain location other than the time domain location of the DMRS of the first data channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0687] For example, in the above-mentioned manner A-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); for this, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced by the manner A-1.

[0688] For another example, in the above-mentioned manner A-2, A-3 or A-4, the resource pattern of the second resource is the same as the resource pattern of the PDSCH DMRS in NR (or 5G, or 5G NR); for this, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH DMRS on the second resource can be avoided or reduced by the manner A-2, A-3 or A-4.

[0689] For another example, in the above-mentioned manner A-5, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); for this, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced by the manner A-5.

[0690] Optionally, the third resource does not include the DMRS resource of the first data channel, in this way, the influence and / or interference caused by the transmission of the first data channel on the DMRS resource of the first data channel can be avoided, so as to improve the data demodulation performance of the first data channel.

[0691] Optionally, the resource pattern of the second resource includes the following manner B-1 and / or manner B-2.

[0692] Manner B-1. The resource pattern of the second resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit.

[0693] Manner B-2. The resource pattern of the second resource includes one subcarrier in one frequency domain unit. The one subcarrier can be subcarrier 0, subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 5, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, or subcarrier 11.

[0694] Based on the manner B, the third resource of the first data channel transmitted by the first communication device does not include the second resource of the at least one resource pattern. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced.

[0695] For example, in the above-mentioned manner B-1, the resource pattern of the second resource is the same as the resource pattern of the PBCH DMRS in NR (or 5G, or 5G NR); therefore, by means of B-1, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PBCH DMRS on the second resource can be avoided or reduced.

[0696] For another example, in the above-mentioned manner B-2, the resource pattern of the second resource is the same as the resource pattern of the PDSCH PTRS in NR (or 5G, or 5G NR); therefore, by means of B-2, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of the PDSCH PTRS on the second resource can be avoided or reduced.

[0697] In a possible implementation, the method further includes: the first communication apparatus receiving fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource. Specifically, the first communication apparatus can further receive the fourth configuration information, so that the first communication apparatus can determine, through the fourth configuration information, that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, so as to enable the first communication apparatus to implement the receiving or transmitting of the first data channel based on the TBS associated with the third resource, improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0698] Optionally, the first configuration information and the fourth configuration information can be the same configuration information or different configuration information.

[0699] Optionally, the first configuration information and / or the fourth configuration information can be physical layer signaling such as DCI, or high layer signaling such as MAC signaling or RRC signaling.
