Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0041] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0042] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0043] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0044] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0045] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0046] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include other numbers of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0052] It should be noted that Figure 1 is merely an example of a system applicable to this application. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit its specific implementation method. For example, predefined can refer to a definition in a protocol. It should also be understood that in the embodiments of the present application, the “protocol” can refer to a standard protocol in the field of communications, such as an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.

[0053] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0054] Operators all have multiple, non-contiguous, narrow bandwidth frequency resources. For example, Operator A is allocated 30 Mbps of bandwidth in the 1.9 GHz band, 15 Mbps in the 2.0 GHz band, and 50 Mbps in the 2.3 GHz band. Operator B is allocated 20 Mbps of bandwidth in the 1.7 GHz band, 20 Mbps in the 1.8 GHz band, 20 Mbps in the 2.3 GHz band, and 20 Mbps in the 2.5 GHz band. Operator C is allocated 15 Mbps of bandwidth in the 1.7 GHz band, 15 Mbps in the 1.8 GHz band, 20 Mbps in the 2.3 GHz band, and 20 Mbps in the 2.6 GHz band.

[0055] The NR system can support a maximum bandwidth of 100 MHz in the frequency band below 6 GHz. One way to deploy the NR system using existing frequency domain resources is to use carrier aggregation (CA) technology, that is, to configure multiple serving cells for the UE, so that the UE can receive / send data in multiple cells simultaneously. Taking Figure 2 as an example, the UE is configured with two serving cells, with bandwidths of 30 MHz from 1885 MHz to 1915 MHz and 50 MHz from 2320 MHz to 2370 MHz, respectively. In this case, the UE's maximum transmission bandwidth is equivalent to 80 MHz.

[0056] The CA working mode may result in some redundant information transmission. For example, each component carrier can operate independently, that is, a component carrier operates independently as a serving cell. Therefore, each component carrier transmits synchronization signals, system information, etc. For a UE configured with CA, reading multiple sets of system information is obviously redundant. If multiple component carriers can be managed in a unified manner, such as sharing system information, the total overhead in the system can be significantly reduced. Therefore, a new multi-carrier working scheme has been proposed, that is, multiple carriers work together as a serving cell. The synchronization signal block (Synchronization Signal / PBCH Block, SSB) used to implement cell search can be transmitted within only one carrier. After the UE reads the system information within one carrier, it can obtain the configuration information on multiple carriers.

[0057] To improve transmission reliability, the NR system supports repeated transmissions for a physical channel. In related technologies, repeated transmissions are only sent at different times in the time domain. This means that in order to improve the reliability of the physical channel, more time domain resources need to be used to transmit the physical channel, and the corresponding transmission time domain will be significantly improved. For latency-sensitive services such as XR and ultra-reliable low latency (URLLC) services, time domain repetition is obviously not ideal.

[0058] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0059] The data transmission method provided in the embodiment of the present application is applied to a terminal device, as shown in FIG3 , and includes:

[0060] S301. The terminal device sends or receives a first number of physical channels, where the first number of physical channels includes a first physical channel and a second physical channel. The frequency domain resources of the first physical channel and the frequency domain resources of the second physical channel belong to different frequency domain resource sets, and the frequency domain resources of different frequency domain resource sets are different. The first number is greater than 1, and the first number of physical channels is used to transmit first information.

[0061] The data transmission method provided in the embodiment of the present application is applied to a network device, as shown in FIG4 , and includes:

[0062] S401. A network device sends or receives a first number of physical channels, where the first number of physical channels includes a first physical channel and a second physical channel. The first frequency domain resources of the first physical channel and the second frequency domain resources of the second physical channel belong to different frequency domain resource sets, and the frequency domain resources of different frequency domain resource sets are different. The first number is greater than 1, and the first number of physical channels are used to transmit first information.

[0063] The data transmission method provided in an embodiment of the present application is applied to a communication system including a terminal device and a network device, wherein the terminal device is used to execute the data transmission method shown in Figure 3, and the network device is used to execute the data transmission method shown in Figure 4.

[0064] In an embodiment of the present application, a first number of physical channels are interacted between the terminal device and the network device, and the first number of physical channels are used to transmit the same information, that is, the first number of physical channels are used for repeated transmission, wherein the information transmitted on the first number of physical channels all includes the first information.

[0065] In a scenario where the first physical channel is sent by the terminal device, the physical channel in the first number of physical channels is an uplink physical channel, such as a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

[0066] In a scenario where the first physical channel is received by the terminal device, the physical channels in the first number of physical channels are downlink physical channels, such as a physical downlink shared channel (Physical Downlink Shared Channel).

[0067] Taking the physical channel as PUSCH as an example, the terminal device sends a first number of PUSCHs to the network device, the network device receives the first number of PUSCHs, and the first number of PUSCHs are used to transmit the same information.

[0068] Taking the physical channel as PDSCH as an example, the network device sends a first number of PDSCHs to the terminal device, the terminal device receives the first number of PDSCHs, and the first number of PDSCHs are used to transmit the same information.

[0069] The first number of physical channels includes a first physical channel and a second physical channel. The frequency domain resources of the first physical channel belong to a first frequency domain resource set, and the frequency domain resources of the second physical channel belong to a second frequency domain resource set. The frequency domain resources of the first frequency domain resource set are different from the frequency domain resources of the second frequency domain resource set.

[0070] It can be understood that the frequency domain resources of the physical channel can be understood as the frequency domain resources occupied by the physical channel or the frequency domain resources allocated or configured by the physical channel.

[0071] It can be understood that the first number of physical channels include physical channels whose frequency domain resources belong to different frequency domain resource sets, or physical channels transmitted on different frequency domain resource sets.

[0072] In an embodiment of the present application, a first number of physical channels are transmitted on a second number of frequency domain resource sets, the frequency domain resources of different frequency domain resource sets in the second number of frequency domain resource sets are different, the second number is greater than 1, and the first number is greater than or equal to the second number.

[0073] If the first number is equal to the second number, one physical channel is transmitted on one frequency domain resource set, and different physical channels are transmitted on different frequency domain resource sets.

[0074] If the first number is greater than the second number, at least one physical channel is transmitted on one frequency domain resource set. Different physical channels transmitted on different frequency domain resource sets have different frequency domain resources, and physical channels transmitted on the same frequency domain resource set have the same frequency domain resources.

[0075] In some embodiments, the first number of physical channels includes a third physical channel and a fourth physical channel, and the frequency domain resources of the third physical channel and the frequency domain resources of the fourth physical channel belong to the same frequency domain resource set, then the time domain resources of the third physical channel and the time domain resources of the fourth physical channel are different.

[0076] The third physical channel and the fourth physical channel are physical channels transmitted on the same frequency domain resource, that is, the frequency domain resources are two different physical channels belonging to the same frequency domain resource set.

[0077] It can be understood that either the third physical channel or the fourth physical channel can also be considered as the first physical channel or the second physical channel.

[0078] If at least two physical channels are transmitted on a frequency domain resource set, time domain resources of different physical channels in the at least two physical channels transmitted on the frequency domain resources are different.

[0079] In the embodiment of the present application, the frequency domain resource set includes one of the following: a carrier, a bandwidth part (Bandwidth Part, BWP), at least one subcarrier, and at least one resource block (Resource Block, RB).

[0080] In one example, the frequency domain resource set is a carrier, and four physical channels are transmitted on three carriers: carrier 0, carrier 1, and carrier 2: physical channel 0, physical channel 1, physical channel 2, and physical channel 3. The frequency domain resources of carrier 0, carrier 1, and carrier 2 are different. Physical channel 0 and physical channel 1 are transmitted on carrier 0, physical channel 2 is transmitted on carrier 1, and physical channel 4 is transmitted on carrier 3. The frequency domain resources occupied by physical channel 0 and physical channel 1 belong to carrier 0, the frequency domain resources occupied by physical channel 2 belong to carrier 1, and the frequency domain resources occupied by physical channel 2 belong to carrier 2. Physical channel 0 and physical channel 1 occupy the same frequency domain resources but different frequency domain resources, and physical channel 0 (physical channel 1) and physical channel 2 and physical channel 3 occupy different frequency domain resources.

[0081] The data transmission method provided in the embodiment of the present application is that the network device sends or receives a first number of physical channels, and the terminal device receives or sends the first number of physical channels, the first number of physical channels includes a first physical channel and a second physical channel, the frequency domain resources of the first physical channel and the frequency domain resources of the second physical channel belong to different frequency domain resource sets, the frequency domain resources of different frequency domain resource sets are different, the first number is greater than 1, and the first number of physical channels is used to transmit the first information, thereby performing repeated transmission on different frequency domain resources in the frequency domain, providing high reliability while significantly reducing transmission delay.

[0082] In some embodiments, the time domain resource of the first physical channel is determined in one of the following ways:

[0083] Time domain resource determination method 1: determining based on one of at least two first time domain resource indication information included in the first configuration information;

[0084] The second time domain resource determination method is based on second time domain resource indication information included in the second configuration information.

[0085] The first physical channel is one of the first number of physical channels. The second physical channel is another physical channel in the first number of physical channels that is different from the first physical channel. The first physical channel and the second physical channel are relative. For example, in physical channel 0 and physical channel 1, the first physical channel can be considered as physical channel 0 and the second physical channel as physical channel 1, or the first physical channel can be considered as physical channel 1 and the second physical channel as physical channel 0. Therefore, any physical channel in the first number of physical channels can be understood as the first physical channel, and the method for determining the time domain resources occupied by any physical channel can be described as the method for determining the time domain resources occupied by the first physical channel.

[0086] It can be understood that the time domain resources of the physical channel can be understood as the time domain resources occupied by the physical channel or the frequency-time domain resources allocated or configured for the physical channel.

[0087] In the first time domain resource determination method, the terminal device or the network device determines the time domain resource of the first physical channel based on one first time domain resource indication information among multiple first time domain resource indication information included in the first configuration information.

[0088] The first configuration information is directly used to configure the time domain resources of each physical channel in the first number of physical channels. The first configuration information includes multiple first time domain resource indication information, and the time domain resources of a physical channel in the first number of physical channels are determined based on the first time domain resource indication information. The first time domain resource indication information is used to determine the position and / or number of time domain symbols occupied by the corresponding physical channel or the physical channels in the corresponding frequency domain resource set.

[0089] The first configuration information includes one of the following: downlink control information or high-layer signaling.

[0090] In some embodiments, the first time domain resource indication information may be time domain resource allocation (TDRA) information included in the first configuration information.

[0091] In some embodiments, the number of first time domain resource indication information included in the first configuration information is less than or equal to the first number.

[0092] If the number of first time domain resource indication information included in the first configuration information is equal to the first quantity, then one piece of first time domain resource indication information is used to indicate the time domain resources occupied by one physical channel.

[0093] If the number of first time domain resource indication information included in the first configuration information is less than the first number, one piece of first time domain resource indication information is used to indicate the time domain resources occupied by one or more physical channels.

[0094] In some embodiments, a first time domain resource indication information is used to indicate a time domain resource of a physical channel; or a first time domain resource indication information is used to determine a time domain resource of a physical channel transmitted within a frequency domain resource set.

[0095] If one first time domain resource indication information is used to indicate the time domain resource of a physical channel, different physical channels are indicated based on different first time domain resource indication information, thereby achieving independent configuration of the time domain resources occupied by different physical channels.

[0096] In one example, the first configuration information includes the following first time domain resource indication information: information A, information B, and information C, and the first configuration information is used to indicate the time domain resources occupied by three physical channels: physical channel 0, physical channel 1, and physical channel 2, wherein information A is used to indicate the time domain resources occupied by physical channel 0, information B is used to indicate the time domain resources occupied by physical channel 1, and information C is used to indicate the time domain resources occupied by physical channel 2.

[0097] If a first time domain resource indication information is used to determine the time domain resources of a physical channel transmitted on a frequency domain resource set, then the time domain resources of different physical channels transmitted on a frequency domain resource are determined based on the same first time domain resource indication information, and the physical channels transmitted on different frequency domain resource sets are indicated based on different first time domain resource indication information, thereby realizing independent configuration of the time domain resources occupied by the physical channels on different frequency domain resource sets.

[0098] In one example, the first configuration information includes the following first time domain resource indication information: information A, information B, and information C, and the first configuration information is used to determine the time domain resources occupied by the physical channels on three frequency domain resource sets: frequency domain resource set 0, frequency domain resource set 1, and frequency domain resource set 2, wherein physical channel 0 is transmitted on frequency domain resource set 0, physical channel 1 is transmitted on frequency domain resource set 1, and physical channel 2 is transmitted on frequency domain resource set 2, then information A is used to indicate the time domain resources occupied by physical channel 0, information B is used to indicate the time domain resources occupied by physical channel 1, and information C is used to indicate the time domain resources occupied by physical channel 2.

[0099] In one example, the first configuration information includes the following first time domain resource indication information: information A, information B, and information C, and the first configuration information is used to determine the time domain resources occupied by the physical channels on three frequency domain resource sets: frequency domain resource set 0, frequency domain resource set 1, and frequency domain resource set 2, wherein physical channel 0 and physical channel 1 are transmitted on frequency domain resource set 0, physical channel 2 is transmitted on frequency domain resource set 1, and physical channel 3 is transmitted on frequency domain resource set 2. Then, information A is used to determine the time domain resources occupied by physical channel 0 and physical channel 1, information B is used to indicate the time domain resources occupied by physical channel 2, and information C is used to indicate the time domain resources occupied by physical channel 3.

[0100] It is understandable that if a first time domain resource indication information is used to determine the time domain resources of a physical channel within a frequency domain resource set, and a frequency domain resource set includes multiple physical channels, then the first time domain resource indication information is used to indicate the time domain interval constituted by the time domain resources occupied by the multiple physical channels included in the frequency domain resource set, and the time domain resources occupied by each physical channel belong to the time domain interval. Among them, the physical channels within a frequency domain resource set can be understood as physical channels transmitted within or on the frequency domain resource set.

[0101] For the first time domain resource configuration method, the time domain resources occupied by different physical channels or the time domain resources occupied by physical channels in different frequency domain resource sets are independently configured by different first time domain resource indication information, thereby achieving flexible configuration of time domain resources.

[0102] In the second time domain resource determination method, the terminal device or the network device determines the time domain resource of the first physical channel based on second time domain resource indication information included in the second configuration information.

[0103] The second configuration information includes second time domain resource indication information, and the time domain resource occupied by each physical channel in the first number of physical channels is determined based on the second time domain resource indication information. The second time domain resource indication information is used to indicate the position and / or number of time domain symbols occupied by the physical channel on a frequency domain resource set.

[0104] The second configuration information includes one of the following: downlink control information or higher layer signaling.

[0105] In some embodiments, the second time domain resource indication information may be TDRA information included in the second configuration information.

[0106] In the second time domain resource configuration method, the time domain resources of at least one physical channel in different frequency domain resource sets are determined based on a second time domain resource indication information, thereby obtaining the time domain resources of multiple physical channels according to the second time domain resource indication information, and the signaling overhead is small.

[0107] In some embodiments, the time domain resources of the first physical channel are determined based on the second time domain resource indication information and a first sub-carrier spacing (SCS).

[0108] The second time domain resource indication information is used to indicate the position and / or number of time domain symbols occupied by a physical channel on a frequency domain resource set. For different frequency domain resource sets or physical channels on different frequency domain resource sets, the corresponding SCSs are different or the same. If different frequency domain resource sets or physical channels on different frequency domain resource sets correspond to different SCSs, then the different frequency domain resource sets or physical channels on different frequency domain resource sets have different sizes of time domain units occupied, where a time domain unit may include: a time slot and a time domain symbol.

[0109] The terminal device or network device uses the first SCS as a reference SCS and determines the time domain resources occupied by the physical channel within a frequency domain resource set based on the second time domain resource indication information and the first SCS.

[0110] In some embodiments, the first SCS is configured by a network device or determined by a protocol agreement or according to an agreed first rule.

[0111] If the first SCS is configured by a network device, the network device may directly configure the first SCS, and the network device may configure a frequency domain resource set, with the first SCS being the SCS corresponding to the frequency domain resource set. In some embodiments, the frequency domain resource set configured by the network device may be one of the second number of frequency domain resource sets.

[0112] The first rule includes one of the following:

[0113] Rule 1: the minimum or maximum SCS among the at least two SCSs corresponding to the first number of physical channels;

[0114] Rule 2: the minimum or maximum SCS among the at least two SCSs corresponding to the second number of frequency domain resource sets where the first number of physical channels are located;

[0115] Rule 3: The SCS corresponding to the frequency domain resource set with the largest or smallest number among the second number of frequency domain resource sets where the first number of physical channels are located.

[0116] In some embodiments, the time domain resources of the first physical channel belong to a first time domain interval, and the first time domain interval is determined based on the second time domain resource indication information and the first SCS; or,

[0117] The time domain resources of the first physical channel are determined based on the second time domain resource indication information, the first SCS and the second SCS, where the second SCS is the SCS corresponding to the first physical channel or the SCS corresponding to the first frequency domain resource set where the first physical channel is located.

[0118] In a scenario where the time domain resources of the first physical channel belong to the first frequency domain interval, the terminal device or network device determines the first frequency domain interval based on the second time domain resource indication information and the first SCS, and determines the time domain resources of the first physical channel based on the first frequency domain interval.

[0119] The terminal device determines a first time domain interval in the time domain of a frequency domain resource set as the time domain resources occupied by the physical channels within the frequency domain resource set. In this case, the time domain resources occupied by the first physical channel include time domain symbols belonging to the first time domain interval. The time domain resources occupied by the physical channels in different frequency domain resource sets are the same.

[0120] In one example, the first time domain interval determined based on the second time domain resource indication information and the first SCS is shown in Figure 5. The time domain resources occupied by the physical channels within the frequency domain resource set 1 and the physical channels within the frequency domain resource set 2 are both the first time domain interval, wherein the physical channels within the frequency domain resource set 1 include physical channel 0, and the physical channels within the frequency domain resource set 2 include physical channel 1 and physical channel 2. The time domain resources occupied by physical channel 0 are the first time domain interval on frequency domain resources 1, and the time domain resources occupied by physical channel 1 and physical channel 2 are the first time domain interval on frequency domain resources 2.

[0121] In some embodiments, if the time domain resources of the first physical channel belong to the first time domain interval, then:

[0122] The time domain resources of the first physical channel are time domain resources within the first time domain interval; or,

[0123] The time domain resources of the first physical channel are time domain resources available in the first time domain interval; or,

[0124] The time domain resources of the first physical channel are time domain resources belonging to a time domain unit within the first time domain interval; or,

[0125] The time domain resources of the first physical channel are available time domain resources belonging to a time domain unit within the first time domain interval.

[0126] The time domain resources of the first physical channel are the time domain resources within the first time domain interval, which can be understood as the time domain resources of the first physical channel include time domain symbols within the first time domain interval.

[0127] The time domain resources of the first physical channel are the available time domain resources within the first time domain interval, which can be understood as the time domain resources of the first physical channel include the available time domain symbols within the first time domain interval.

[0128] The time domain resources of the first physical channel are time domain resources belonging to a time domain unit in the first time domain interval, which can be understood as the time domain resources of the first physical channel are time domain symbols belonging to a time domain unit in the first time domain interval.

[0129] The time domain resources of the first physical channel are available time domain resources belonging to a time domain unit within the first time domain interval, which can be understood as the time domain resources of the first physical channel are available time domain symbols belonging to a time domain unit within the first time domain interval.

[0130] The time domain resources occupied by a physical channel may or may not have the following restriction: 1. Transmission cannot cross time domain units.

[0131] If the time domain resources occupied by the physical channel have restriction condition 1, the time domain resources of the physical channel cannot be transmitted across time domain units, that is, they can only be transmitted within one time domain unit.

[0132] If the time domain resources occupied by the physical channel do not meet the first restriction condition, the time domain resources of the physical channel can be transmitted across time domain units, that is, can be transmitted within one or more time domain units.

[0133] The distribution of the time domain resources of the first physical channel includes one of the following:

[0134] Case 1: If the first physical channel can be transmitted across time domain units and the first time domain interval includes one or more time domain units, the time domain resources of the first physical channel are the time domain resources within the first time domain interval.

[0135] Case 2: If the first physical channel cannot be transmitted across time domain units and the first time domain interval belongs to a time domain unit, the time domain resources of the first physical channel are the time domain resources within the first time domain interval, or the time domain resources of the first physical channel are the time domain resources belonging to a time domain unit within the first time domain interval.

[0136] Case 3: If the first physical channel cannot be transmitted across time domain units and the first time domain interval belongs to multiple time domain units, the time domain resources of the first physical channel are the time domain resources belonging to one time domain unit in the first time domain interval.

[0137] In an example, as shown in FIG6 , the time domain resources of the physical channel 0 are time domain resources within the first time domain interval.

[0138] In one example, as shown in FIG7 , the time domain resources of physical channel 1 are the time domain resources belonging to time slot 0 in the first time domain interval, and the time domain resources of physical channel 2 are the time domain resources belonging to time slot 1 in the first time domain interval.

[0139] It can be understood that the time domain resources occupied by a physical channel belong to the available resources in the first time domain interval.

[0140] The distribution of the time domain resources of the first physical channel includes one of the following:

[0141] In case 4 based on case 1, the time domain resources of the first physical channel are available time domain resources within the first time domain interval.

[0142] In case 5 based on case 2, the time domain resources of the first physical channel are available time domain resources within the first time domain interval, or the time domain resources of the first physical channel are available time domain resources belonging to a time domain unit within the first time domain interval.

[0143] In case 6 based on case 3, the time domain resources of the first physical channel are available time domain resources belonging to a time domain unit within the first time domain interval.

[0144] It is understandable that the available time domain resources in the first time domain interval are time domain resources other than the unavailable resources in the first time domain interval. The first time domain interval may or may not include unavailable time domain resources. In a scenario where the first time domain interval does not include unavailable time domain resources, the available time domain resources in the first time domain interval are continuous. In a scenario where the first time domain interval includes unavailable time domain resources, the available time domain resources in the first time domain interval are discontinuous.

[0145] The time domain resources of a physical channel may or may not meet the following constraint 2: being continuous in the time domain.

[0146] If the time domain resources of a physical channel do not meet the second restriction condition, the available time domain resources in the first time domain interval or the available time domain resources belonging to a time domain unit in the first time domain interval are the time domain resources of a physical channel.

[0147] If the time domain resources of a physical channel have restriction condition 2, the continuous available time domain resources in the first time domain interval or the continuous available time domain resources belonging to a time domain unit in the first time domain interval are the time domain resources of a physical channel. If the available time domain resources of the first time domain interval are divided into multiple continuous available time domain resources based on unavailable resources, the time domain resources of the first time domain interval include the time domain resources of multiple physical channels. If the available time domain resources belonging to a time domain unit in the first time domain interval are divided into multiple continuous available time domain resources based on unavailable resources, the available time domain resources belonging to the time domain unit in the first time domain interval include the time domain resources of multiple physical channels.

[0148] In one example, as shown in Figure 8A, the time domain resources of a physical channel do not have restriction condition 2. The time domain resources of physical channel 0 are the available time domain resources belonging to time slot 0 within the first time domain interval and are discontinuous in the time domain. The time domain resources of physical channel 1 are the available time domain resources belonging to time slot 1 within the first time domain interval.

[0149] In one example, as shown in Figure 8B, there is restriction condition two on the time domain resources of a physical channel. The time domain resources of physical channel 0 are the available time domain resources 1 belonging to time slot 0 within the first time domain interval, the time domain resources of physical channel 1 are the available time domain resources 2 belonging to time slot 0 within the first time domain interval, and the time domain resources of physical channel 2 are the available time domain resources belonging to time slot 1 within the first time domain interval.

[0150] Among them, the shaded part in Figures 8A and 8B is the unavailable time domain resource belonging to time slot 0 in the first time domain interval, and among the time domain resources belonging to time slot 0 in the first time domain interval, the unavailable time domain resource is preceded by the available time domain resource 1 belonging to time slot 0 in the first time domain interval, and the unavailable resource is followed by the available time domain resource 2 belonging to time slot 0 in the first time domain interval.

[0151] In some embodiments, the available time domain resources in the first time domain interval are time domain resources other than the unavailable time domain resources in the first time domain interval, and the unavailable time domain resources include at least one of the following:

[0152] Symbols of transmission direction conflicts;

[0153] Symbols occupied by the synchronization signal block (Synchronizing Signal / PBCH Block, SSB);

[0154] Unavailable symbols for network device configuration;

[0155] the symbol occupied by the reference signal;

[0156] Symbols occupied by the control-resource set (CORESET).

[0157] Whether a symbol, i.e., a time-domain symbol, is a symbol with a transmission direction conflict is determined based on the transmission direction of the physical channel. If the physical channel is an uplink physical channel, then symbols used for downlink transmission (i.e., downlink symbols) or symbols with flexible transmission direction (i.e., flexible symbols) are symbols with a transmission direction conflict. If the physical channel is a downlink physical channel, then symbols used for uplink transmission (i.e., uplink symbols) or symbols with flexible transmission direction (i.e., flexible symbols) are symbols with a transmission direction conflict.

[0158] The reference signal includes one or more of a channel status indicator reference signal (CSI-RS), a sounding reference signal (SRS), and the like.

[0159] In some embodiments, if the number of symbols included in the time domain resources belonging to a time domain unit in the first time domain interval or the available time domain resources belonging to a time domain unit in the first time domain interval is less than or equal to a third number, the time domain resources belonging to a time domain unit in the first time domain interval or the available time domain resources belonging to a time domain unit in the first time domain interval are not used for reception or transmission of the first physical channel.

[0160] At this time, the number of symbols included in the time domain resources of the first physical channel is greater than the third number. The size of the third number can be configured or pre-set by the network device or agreed upon by protocol.

[0161] In a scenario where the time domain resources of the first physical channel are determined based on the second time domain resource indication information, the first SCS and the second SCS, the terminal device or the network device determines the time domain resources of the first physical channel based on the second time domain resource indication information, the first SCS and the second SCS.

[0162] It can be understood that the second time domain resource indication information and the first SCS are used to determine the first time domain interval. Here, when determining the time domain resources of the first physical channel, it is not necessary to determine the first time domain interval, and it is directly determined based on the second time domain resource indication information and the first SCS and the second SCS.

[0163] The first frequency domain resource set where the first physical channel is located can be understood as the frequency domain resources of the first physical channel belonging to the first frequency domain resource set.

[0164] In some embodiments, the time domain resources of the first physical channel are determined based on the second time domain resource indication information and a first parameter, and the first parameter is related to the first SCS and the second SCS.

[0165] The second SCS is the same as or different from the first SCS. In one example, the first SCS is 15 kHz and the second SCS is 15 kHz. In one example, the first SCS is 15 kHz and the second SCS is 30 kHz. In one example, the first SCS is 30 kHz and the second SCS is 15 kHz.

[0166] The terminal device or network device determines a first parameter based on the first SCS and the second SCS. In one example, the first parameter is a ratio of the second SCS to the first SCS. In one example, the first parameter is a ratio of the first SCS to the second SCS.

[0167] The terminal device or network device determines the symbol index S and / or symbol quantity L of the starting symbol indicated by the second time domain resource indication information, determines the symbol index of the starting symbol of the first physical channel based on S and the first parameter, and / or determines the number of symbols included in the time domain resources of the first physical channel based on L and the first parameter.

[0168] In one example, the first parameter is the ratio of the second SCS to the first SCS, the symbol index of the starting symbol of the first physical channel is S multiplied by the first parameter, and the number of symbols included in the time domain resources of the first physical channel is L.

[0169] In one example, the first parameter is the ratio of the first SCS to the second SCS, the symbol index of the starting symbol of the first physical channel is S divided by the first parameter, and the number of symbols included in the time domain resources of the first physical channel is L.

[0170] In one example, the first parameter is the ratio of the second SCS to the first SCS, the symbol index of the starting symbol of the first physical channel is S, and the number of symbols included in the time domain resources of the first physical channel is L multiplied by the first parameter.

[0171] In one example, the first parameter is the ratio of the first SCS to the second SCS, the symbol index of the starting symbol of the first physical channel is S, and the number of symbols included in the time domain resources of the first physical channel is L divided by the first parameter.

[0172] In one example, the first parameter is the ratio of the second SCS to the first SCS, the symbol index of the starting symbol of the first physical channel is S multiplied by the first parameter, and the number of symbols included in the time domain resources of the first physical channel is L multiplied by the first parameter.

[0173] In one example, the first parameter is the ratio of the first SCS to the second SCS, the symbol index of the starting symbol of the first physical channel is S divided by the first parameter, and the number of symbols included in the time domain resources of the first physical channel is L divided by the first parameter.

[0174] In some embodiments, the frequency domain resources of the first physical channel are determined in one of the following ways:

[0175] Frequency domain resource determination method 1: determining based on one of at least two first frequency domain resource indication information included in the third configuration information;

[0176] The second method for determining the frequency domain resources is to determine based on second frequency domain resource indication information included in the fourth configuration information.

[0177] In the first frequency domain resource determination method, the terminal device or the network device determines the frequency domain resource of the first physical channel based on one first frequency domain resource indication information among multiple first frequency domain resource indication information included in the third configuration information.

[0178] The third configuration information is directly used to configure the frequency domain resources of each physical channel in the first number of physical channels. The third configuration information includes multiple pieces of first frequency domain resource indication information, and the frequency domain resources of one physical channel in the first number of physical channels are determined based on the piece of first frequency domain resource indication information. The first frequency domain resource indication information is used to determine the location and / or number of resource blocks occupied by the corresponding physical channel or the physical channels in the corresponding frequency domain resource set.

[0179] The third configuration information includes one of the following: downlink control information or higher layer signaling.

[0180] In some embodiments, the number of the first frequency domain resource indication information included in the third configuration information is less than or equal to the first number.

[0181] If the number of first frequency domain resource indication information included in the third configuration information is equal to the first number, then one piece of first frequency domain resource indication information is used to indicate the frequency domain resources occupied by one physical channel.

[0182] If the number of first frequency domain resource indication information included in the third configuration information is less than the first number, one piece of first frequency domain resource indication information is used to indicate the frequency domain resources occupied by one or more physical channels on a frequency domain resource set.

[0183] In some embodiments, one of the first frequency domain resource indication information is used to determine the frequency domain resources of a physical channel transmitted within the frequency domain resource set.

[0184] If a frequency domain resource set transmits a physical channel, the first frequency domain resource indication information corresponding to the frequency domain resource set is used to indicate the frequency domain resources of the physical channel. If a frequency domain resource set transmits multiple physical channels, the first frequency domain resource indication information indicates the frequency domain resources occupied by the multiple physical channels, and the frequency domain resources occupied by different physical channels are the same.

[0185] For the first frequency domain resource configuration mode, the frequency domain resources occupied by physical channels in different frequency domain resource sets are independently configured by different first frequency domain resource indication information, thereby achieving flexible configuration of frequency domain resources.

[0186] In the second frequency domain resource determination method, the terminal device or the network device determines the frequency domain resources of the first physical channel based on a second frequency domain resource indication information included in the fourth configuration information.

[0187] The fourth configuration information includes second frequency domain resource indication information, and the frequency domain resources of each physical channel in the first number of physical channels are determined based on the second frequency domain resource indication information. The second frequency domain resource indication information is used to indicate the position and / or number and / or bandwidth of RBs occupied by the physical channels on a frequency domain resource set.

[0188] The fourth configuration information includes one of the following: downlink control information or higher layer signaling.

[0189] In the second frequency domain resource configuration method, the frequency domain resources of the physical channels in different frequency domain resource sets are determined based on a second frequency domain resource indication information, thereby obtaining the frequency domain resources of the physical channels on multiple frequency domain resource sets according to the second frequency domain resource indication information, and the signaling overhead is small.

[0190] In some embodiments, the frequency domain resources of the first physical channel are determined based on the second frequency domain resource indication information and the first SCS.

[0191] For different frequency domain resource sets or physical channels on different frequency domain resource sets, the corresponding SCSs are different or the same. If different frequency domain resource sets or physical channels on different frequency domain resource sets correspond to different SCSs, then the sizes of the RBs occupied by the different frequency domain resource sets or physical channels on different frequency domain resource sets are different.

[0192] The terminal device or network device uses the first SCS as a reference SCS and determines the frequency domain resources of a frequency domain resource set, that is, the frequency domain resources occupied by the physical channels within the frequency domain resource set, based on the second frequency domain resource indication information and the first SCS.

[0193] In some embodiments, the frequency domain resources of the first physical channel are determined based on a first frequency domain interval, and the first frequency domain interval is determined based on the second frequency domain resource indication information and the first SCS; or,

[0194] The frequency domain resources of the first physical channel are determined based on the second frequency domain resource indication information and the first SCS and the second SCS. The second SCS is the SCS corresponding to the first physical channel or the SCS corresponding to the first frequency domain resource set where the first physical channel is located.

[0195] In a scenario where the frequency domain resources of the first physical channel are determined based on a first frequency domain interval, and the first frequency domain interval is determined based on the second frequency domain resource indication information and the first SCS, the terminal device or network device determines the first frequency domain interval based on the second frequency domain resource indication information and the first SCS, and determines the frequency domain resources of the first physical channel based on the first frequency domain interval.

[0196] The second frequency domain resource indication information indicates the starting RB and / or the number of RBs and / or the bandwidth occupied by the RB, but the size of an RB is determined based on the first SCS. Therefore, the second frequency domain resource indication information and the first SCS can determine a frequency domain interval of fixed size, namely the first frequency domain interval.

[0197] In some embodiments, the frequency domain resources of the first physical channel are the same as at least one of the following of the first frequency domain interval: a starting resource block RB, the number of RBs, and a bandwidth occupied by RBs.

[0198] In one example, the frequency domain resources of each frequency domain resource set use the same starting RB and the same number of RBs. In this case, the starting RB of the frequency domain resources of the first physical channel is the same as the starting RB of the first frequency domain interval, and the number of RBs of the frequency domain resources of the first physical channel is the same as the number of RBs in the first frequency domain interval.

[0199] In one example, the starting RB of the frequency domain resources of the first physical channel is the same as the starting RB of the first frequency domain interval, but the bandwidth occupied by the RB of the frequency domain resources of the first physical channel is the same as the bandwidth occupied by the RB of the first frequency domain interval.

[0200] In one example, the starting RB of the frequency domain resources of the first physical channel is different from the starting RB of the first frequency domain interval, but the bandwidth occupied by the RB of the frequency domain resources of the first physical channel is the same as the bandwidth occupied by the RB of the first frequency domain interval.

[0201] In some embodiments, if the frequency domain resources of the first physical channel and a parameter in the starting RB, the number of RBs, and the bandwidth occupied by RBs of the first frequency domain interval, namely, the frequency domain parameter, are different, the parameter of the first physical channel is determined based on the parameter of the first frequency domain interval, the first SCS, and the second SCS.

[0202] In one example, the frequency domain resources of the first physical channel and the starting RB of the first frequency domain interval are different, the first SCS is 15KHz, the second SCS is 30KHz, and the second parameter is the ratio of the second SCS to the first SCS. The starting RB of the frequency domain resources of the first physical channel is the starting RB of the first frequency domain interval divided by the second parameter.

[0203] In one example, the frequency domain resources of the first physical channel and the number of RBs of the first frequency domain interval are different, the first SCS is 15KHz, the second SCS is 30KHz, and the second parameter is the ratio of the second SCS to the first SCS. The number of RBs of the frequency domain resources of the first physical channel is the number of RBs in the first frequency domain interval divided by the second parameter.

[0204] In the scenario where the frequency domain resources of the first physical channel are determined based on the second frequency domain resource indication information and the first SCS and the second SCS, the terminal device or network device determines the frequency domain resources of the first physical channel based on the second frequency domain resource indication information, the first SCS and the second SCS.

[0205] It can be understood that the second frequency domain resource indication information and the first SCS are used to determine the first frequency domain interval. Here, when determining the frequency domain resources of the first physical channel, it is not necessary to determine the first frequency domain interval. The frequency domain resources of the first physical channel are directly determined based on the second frequency domain resource indication information and the first SCS and the second SCS.

[0206] In some embodiments, the frequency domain resources of the first physical channel are determined based on the second frequency domain resource indication information and a second parameter, and the second parameter is related to the first SCS and the second SCS.

[0207] The second SCS is the same as or different from the first SCS. In one example, the first SCS is 15 kHz and the second SCS is 15 kHz. In one example, the first SCS is 15 kHz and the second SCS is 30 kHz. In one example, the first SCS is 30 kHz and the second SCS is 15 kHz.

[0208] The terminal device or network device determines a second parameter based on the first SCS and the second SCS. In one example, the second parameter is a ratio of the second SCS to the first SCS. In one example, the second parameter is a ratio of the first SCS to the second SCS.

[0209] The terminal device or network device determines the index of the starting RB and / or the number of RBs and / or the bandwidth occupied by the RB indicated by the second frequency domain resource indication information, determines the index of the starting RB of the first physical channel according to the index of the starting RB indicated by the second frequency domain resource indication information and the second parameter, and / or determines the number of RBs included in the frequency domain resources of the first physical channel according to the number of RBs indicated by the second frequency domain resource indication information and the second parameter, and determines the bandwidth occupied by the RBs of the frequency domain resources of the first physical channel according to the bandwidth occupied by the RBs indicated by the second frequency domain resource indication information and the second parameter.

[0210] In some embodiments, the first number of physical channels is used to repeatedly transmit a first transport block TB, and a transport block size TBS of the first TB is determined according to the following parameters of a fifth physical channel: the number of time domain resources, the number of frequency domain resources, and MCS.

[0211] The size of the first TB transmitted by each physical channel is determined based on the number of time domain resources, the number of frequency domain resources, and the MCS of the fifth physical channel in the first number of physical channels. Therefore, the sizes of TBs transmitted by different physical channels are the same, and the TBS of the TBs transmitted by the first number of physical channels is determined based only on the parameters of one physical channel and is applicable to each physical channel in the first number of physical channels.

[0212] In an embodiment of the present application, the size of the TB transmitted by each physical channel in the first number of physical channels does not need to be independently determined based on its own number of time domain resources, number of frequency domain resources, and MCS, so as to avoid introducing scheduling restrictions or sending TBSs of different physical channels that are not exactly the same.

[0213] The fifth physical channel is one of the first number of physical channels or does not belong to the first number of physical channels.

[0214] In some embodiments, the fifth physical channel is one of the following:

[0215] A physical channel in the frequency domain resource set with the smallest number in the second number of frequency domain resource sets where the first number of physical channels are located;

[0216] a physical channel in the frequency domain resource set with the largest number among the second number of frequency domain resource sets;

[0217] A physical channel within a frequency domain resource set having a minimum SCS among the second number of frequency domain resource sets;

[0218] A physical channel within the frequency domain resource set with the largest SCS in the second number of frequency domain resource sets;

[0219] a physical channel within a frequency domain resource set configured by the network device in the second number of frequency domain resource sets;

[0220] The physical channel with the earliest start time among the first number of physical channels;

[0221] A physical channel indicated by the network device.

[0222] In some embodiments, the MCS corresponding to the first physical channel is different from the MCS corresponding to the second physical channel.

[0223] Different MCSs correspond to different physical channels within different frequency domain resource sets. The MCS used by the physical channels on each frequency domain resource set can be independently indicated. That is, the configuration signaling includes multiple MCS indication information fields, with different MCS indication information corresponding to different physical channels to indicate the MCS used by the corresponding physical channels.

[0224] It can be understood that multiple different physical channels on the same frequency domain resource set use the same MCS and are based on the same MCS indication information field indication.

[0225] In some embodiments, redundant version RV information of each physical channel in the first number of physical channels is configured by fifth configuration information, and the fifth configuration information is determined by a sending device that sends the first number of physical channels.

[0226] If the network device sends a first number of physical channels, the terminal device receives the first number of physical channels, and the physical channels are downlink physical channels, the network device indicates the RV information used by each physical channel in the first number of physical channels through the fifth configuration information.

[0227] At this time, the fifth configuration information may be transmitted via the PDCCH or higher layer signaling, or may be mapped to specific resources of the PDSCH in an agreed mapping manner for transmission.

[0228] If the terminal device sends a first number of physical channels, the network device receives the first number of physical channels, and the physical channels are uplink physical channels, the terminal device indicates the RV information used by each physical channel in the first number of physical channels through the fifth configuration information.

[0229] At this time, the fifth configuration information can be mapped to specific resources of the PUSCH through an agreed mapping method for transmission.

[0230] In some embodiments, the RV information of the first physical channel is determined according to an index of the first physical channel.

[0231] At this time, the RV information of each physical channel in the first number of physical channels is determined according to the index of the corresponding physical channel.

[0232] In one example, the initial RV number used for the first physical channel: physical channel 0 is r, and the RV number used by physical channel n is (r+n) mod 4, that is, the remainder of r+n divided by 4.

[0233] In one example, RV information in an RV sequence is sequentially assigned to each physical channel according to the index order of each physical channel. The RV sequence may be {0, 3, 0, 3}, {0, 2, 3, 1}, {0, 0, 0, 0}, and so on. For example, if the RV sequence is {0, 3, 0, 3}, physical channel 0 uses RV number 0, physical channel 1 uses RV number 3, physical channel 2 uses RV number 0, physical channel 3 uses RV number 3, and so on. The RV number used by physical channel n is the (n mod 4)th RV number in {0, 3, 0, 3}. For another example, if the RV sequence is {0, 3, 0, 3}, the starting index i is 1, physical channel 0 uses RV number 3, physical channel 1 uses RV number 0, physical channel 2 uses RV number 3, physical channel 3 uses RV number 0, and so on. The RV number used by physical channel n is the ((n+i) mod 4)th RV number in {0, 3, 0, 3}.

[0234] In some embodiments, the RV information of the first physical channel is an agreed fixed RV.

[0235] At this time, all physical channels use the same RV information, which is a fixed RV as agreed upon.

[0236] In some embodiments, the index of the first physical channel is determined according to a position of a time domain resource of the first physical channel in the time domain and a position of a frequency domain resource of the first physical channel in the frequency domain.

[0237] In some embodiments, the indexing method of the first number of physical channels includes one of the following:

[0238] First according to the end position of the time domain resource and then according to the position of the frequency domain resource;

[0239] First according to the location of the frequency domain resources and then according to the end location of the time domain resources.

[0240] In some embodiments, the second number of frequency domain resource sets where the first number of physical channels are located satisfies at least one of the following:

[0241] Condition 1: the second number of frequency domain resource sets corresponds to the same serving cell;

[0242] Condition 2: the second number of frequency domain resource sets corresponds to the same Hybrid Automatic Repeat reQuest (HARQ) entity;

[0243] Condition three: one frequency domain resource set among the second number of frequency domain resource sets is used by the terminal device to detect a synchronization signal block or receive system information;

[0244] Condition 4: The second number of frequency domain resource sets is configured by a network device.

[0245] The above conditions are not necessary conditions for the second number of frequency domain resource sets.

[0246] The following further describes the data transmission method provided in the embodiments of the present application.

[0247] In the data transmission method provided in the embodiments of the present application, when multiple component carriers are managed as a single cell, they can share a single HARQ entity. This means that the same transport block (TB) can be transmitted across different carriers. In this case, repeated transmission of a physical channel in the frequency domain significantly reduces transmission time while providing high reliability.

[0248] The terminal device receives or sends M (i.e., the first number, greater than or equal to N) physical channels on N (i.e., the second number, greater than 1) frequency domain resource sets, wherein the frequency domain resources occupied by one of the M physical channels belong to a frequency domain resource set, and the M physical channels are used for repeated transmission, that is, transmitting the same information or transmitting the same TB. The frequency domain resource set can be understood as one of the following: carrier, BWP, at least one subcarrier, at least one RB. The physical channel can be an uplink channel or a downlink channel. For example: the physical channel is a physical downlink shared channel PDSCH or a physical uplink shared channel PUSCH.

[0249] The non-essential conditions for a terminal device to receive or transmit M physical channels on N frequency domain resource sets include at least one of the following:

[0250] The N frequency domain resource sets correspond to the same serving cell;

[0251] The terminal detects the SSB or receives the system information in one frequency domain resource set of the N frequency domain resource sets, and does not detect the SSB or receive the system information in other frequency domain sets;

[0252] The N frequency domain resource sets correspond to one HARQ entity;

[0253] The N frequency domain resource sets are configured by the base station.

[0254] The time domain resources, frequency domain resources, TBS, MCS and RV of the physical channel are described below.

[0255] Time domain resources

[0256] There are two ways to configure the time domain resources of the physical channel:

[0257] Time domain resource configuration method 1: The terminal device receives first configuration information, where the first configuration information is used to indicate the time domain resources occupied by at least one physical channel among the M physical channels.

[0258] The first configuration information may be composed of multiple pieces of information, where different pieces of information are used to indicate the time domain resources occupied by different physical channels.

[0259] The first configuration information directly indicates the time domain symbols (position and / or quantity) occupied by the M physical channels. For example, the first configuration information includes multiple TDRA information, where one TDRA indicates the time domain symbols occupied by one physical channel; or one time domain resource allocation indication information includes multiple start length indication (Start and Length Indicator Value, SLIV) information, where one SLIV information is used to indicate the time domain symbols occupied by one physical channel.

[0260] The first configuration information may be DCI or higher layer signaling.

[0261] In the first time domain resource configuration method, time domain resources are independently configured, which has the highest configuration efficiency but large signaling overhead. In this case, M physical channels can be transmitted through different symbols or slots in the time domain.

[0262] Time domain resource configuration method 2: The second configuration information determines the first time domain resource or time domain resource area, and determines the time domain symbol occupied by one physical channel among the M physical channels according to the time domain resource area.

[0263] In the second time domain resource configuration method, time domain resources of multiple physical channels are obtained according to one configuration information, namely, the second configuration information. The signaling overhead is small, and the flexibility is slightly worse than that of the first time domain resource configuration method.

[0264] In one implementation, the second time domain resource configuration method includes the following steps:

[0265] S1. Determine a first time domain resource according to second configuration information and a reference subcarrier spacing.

[0266] The time slot where the first time domain resource is located and the symbols occupied in the slot may be determined.

[0267] The reference subcarrier spacing is configured by the base station or is the same as the SCS used by one of the N frequency domain resource sets (the frequency domain resource set with the smallest or largest number or a resource set configured by the base station or a resource set that transmits the second configuration information or the resource set with the largest SCS or the smallest SCS among the N frequency domain resource sets).

[0268] S2. Determine second time domain resources of each frequency domain resource set in the time domain based on the first time domain resources.

[0269] S3. For a second time domain resource, determine an available time domain resource in the second time domain resource.

[0270] Available time domain resources are the resources remaining after removing unavailable resources from the corresponding second time domain resources. Unavailable resources include at least one of the following: symbols with conflicting transmission directions (for downlink physical channels, uplink symbols or flexible symbols are unavailable symbols; for uplink physical channels, downlink symbols or flexible symbols are unavailable symbols), symbols occupied by SSBs, unavailable symbols configured by the base station, symbols occupied by reference signals such as CSI-RS and SRS, and symbols occupied by CORESETs.

[0271] S4. If the second time domain resource includes symbols in multiple slots, determine that a time domain symbol occupied by a physical channel is a symbol of the second time domain resource in one slot.

[0272] If the number of symbols in a slot belonging to the second time domain resource (available time domain resource) is less than a first threshold, the symbols in the corresponding slot are not used to transmit the physical channel.

[0273] It is understandable that S3 is not a required step but an optional step. If S3 is not executed, then in S4, if the second time domain resource includes symbols in multiple slots, then the time domain symbol occupied by a physical channel is determined to be a symbol of the second time domain resource in one slot; if S3 is executed, then in S4, if the available time domain resources of the second time domain resource include symbols in multiple slots, then the time domain symbol occupied by a physical channel is determined to be a symbol of the available time domain resources of the second time domain resource in one slot.

[0274] In one example, as shown in FIG9 , the reference SCS is 15 kHz, and the time domain resource region is determined to be symbols 3 to 12 in a slot using a 15 kHz SCS according to the second configuration information. The time domain resources for transmitting physical channels in carriers 1, 2, and 3, i.e., the second time domain resources, are determined to be a (complete) region overlapping with the time domain resource region. The available time domain resources for transmitting physical channels in carriers 1, 2, and 3 are determined, with red resources being unavailable resources. It is determined that the available resources in the second time domain resources of carrier 2 include symbols in two slots. A physical channel cannot be transmitted across slots, i.e., a physical channel can only occupy symbols in one slot, so multiple physical channels will be transmitted in carrier 2. If the physical channels are restricted to occupying continuous time domain resources, the first of the two slots included in the second time domain resources of carrier 2 (the shaded portion of the first slot in the second time domain resources of carrier 2 is an unavailable resource) includes two physical channels: physical channel 1 and physical channel 2. If physical channels are not restricted to occupying continuous time domain resources, the discontinuous resources in the first of the two slots included in the second time domain resource of carrier 2 can be used together to transmit a single physical channel (i.e., physical channel 1 and physical channel 2 are combined into one physical channel). The determination method for carrier 3 is similar. Specifically, if the number of available symbols in the first and fourth slots in the second time domain resource of carrier 3 is less than the first threshold, the symbols in the first and fourth slots are not used to transmit the physical channel.

[0275] It can be understood that in the second time domain resource configuration method, the characteristics of the time domain resource area, namely the first time domain resource, may not be reflected. The time domain symbol occupied by the physical channel can be determined based on the second configuration, the reference subcarrier and the subcarrier of the frequency domain resource set where a physical channel is located. The time domain symbol occupied by each physical channel in the physical channel transmitted on the frequency domain resource set can also be determined based on the second configuration information, the reference subcarrier and the subcarrier of the frequency domain resource set.

[0276] Frequency domain resources of physical channels

[0277] The configuration methods of the frequency domain resources of the physical channel include frequency domain resource configuration method 1 and frequency domain resource configuration method 2.

[0278] In the first frequency domain resource configuration method, since the bandwidths of component carriers are different, the frequency domain resources occupied by the physical channels are independently configured for the N frequency domain resource sets.

[0279] In the first frequency domain resource configuration method, frequency domain resources of different frequency domain resource sets are independently configured, which has the highest configuration efficiency but has a large signaling overhead.

[0280] In frequency domain resource configuration mode 2, the same frequency domain resources are used in different frequency domain resource sets to transmit physical channels. It is understandable that the same frequency domain resources do not necessarily mean the same absolute frequency, but rather the same frequency domain resource unit parameters, for example, at least one of the starting RB number (the position of the starting RB relative to the starting point of the frequency domain resource set), the number of RBs, and the bandwidth occupied by the RBs.

[0281] In one example, according to the configuration information, the starting RB is RB n, and the number of RBs is X. Then, RB n to RB n+X-1 are used in each frequency domain resource set.

[0282] In one example, according to the configuration information, the starting RB is RB n, the number of RBs is X, and the reference SCS is 15 kHz. Then, within a carrier with an SCS of 30 kHz, the frequency domain resources used are RB n to RB(n+X-1) / 2 or RB n to RB n+X / 2-1 or RB n / 2 to RB(n+X-1) / 2.

[0283] In the embodiment of the present application, different physical channels among the M physical channels transmitted within the same frequency domain resource set occupy the same frequency domain resources but different time domain resources.

[0284] TBS of TBs transmitted by physical channels

[0285] The terminal device determines the TBS based on the number of time domain resources, the number of frequency domain resources, and the MCS information corresponding to a frequency domain resource set in the N frequency domain resource sets, that is, determines a TBS based on the parameters of a frequency domain resource set, and the TBS is applicable to all physical channels for repeated transmission. The frequency domain resource set used to determine the TBS is configured by the base station or the frequency domain resource set with the smallest or largest subcarrier spacing or the frequency domain resource set with the smallest or largest number.

[0286] MCS corresponding to the physical channel

[0287] The MCS used by the physical channels transmitted by the N frequency domain resource sets is independently indicated, that is, the configuration signaling includes multiple MCS indication information fields, each corresponding to a different physical channel. Different physical channels among the M physical channels transmitted within the same frequency domain resource set use the same MCS.

[0288] RV of physical channel

[0289] There are two ways to determine the RV information of the physical channel:

[0290] Method 1: Sending end indication

[0291] The transmitter can flexibly configure the RV information used according to the actual bit rate of the physical channel.

[0292] For the downlink physical channel PDSCH, the base station indicates the RV information used by each physical channel. The RV information can be transmitted through the PDCCH or higher-layer signaling, or mapped to specific resources on the PDSCH according to a predetermined method for transmission.

[0293] For the uplink physical channel PUSCH, the UE indicates the RV information used by each physical channel. The RV information is mapped to specific resources of the PUSCH for transmission according to the agreed method.

[0294] Method 2: Determine the RV information used by each physical channel according to the index order of the physical channels.

[0295] The M physical channels are indexed in an agreed manner.

[0296] In one example, the agreed manner includes numbering the carrier first and then the time domain end position sequence as shown in FIG10 ; or numbering the time domain end position first and then the carrier number sequence as shown in FIG11 .

[0297] Determining the RV information used by each physical channel according to the index order of the physical channels includes but is not limited to the following examples:

[0298] Example 1: The base station indicates the initial RV number r for physical channel 0, then the RV number used by physical channel n is (r+n) mod 4.

[0299] Example 2: The RV number used by each physical channel is determined in the order of {0, 3, 0, 3} or {0, 2, 3, 1}.

[0300] Example 3: Fixed RV version number, all channels use the same RV version.

[0301] Example 4. Determine the RV number used by each physical channel in the order of {0, 3, 0, 3} or {0, 2, 3, 1} or {0, 0, 0, 0}, that is, the RV number used by physical channel n is the RV version number indexed by (n mod 4) in the sequence (index starts from 0) or the RV version number indexed by ((i+n) mod 4), where i is a given starting index.
