Description

Technical Field

[0001] This application relates to wireless communication networks, such as a method, apparatus, and computer storage medium for configuring transmission resources. Background Technology

[0002] In the fifth generation mobile communication technology (5G), in order to ensure coverage, slot-based aggregation and slot-based repetition based on dynamic scheduling are introduced. This means that the terminal uses multiple time slots to repeatedly send transport blocks (TB), and the TB has the same time and frequency resource allocation in each time slot.

[0003] With the development of 5G, to support ultra-high reliability and ultra-low latency transmission, it is necessary to enhance time slot aggregation based on dynamic scheduling and time slot repetition without scheduling. Therefore, techniques have been introduced to repeatedly transmit a terabyte (TB) once or more within the same time slot, or to repeatedly transmit the same TB across multiple consecutively available time slots. However, whether dynamically scheduled or without scheduling, a collision may occur between the time-domain symbol of a retransmission and the subframe format. Determining the retransmission method in such cases is a pressing issue that needs to be addressed. Summary of the Invention

[0038] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] In mobile communication networks, the transmission of various information mainly occurs between base stations and terminals. Base stations or terminals acquire transmission resources based on pre-configured resources or through other means, thereby enabling the transmission of various information on the defined transmission resources. Here, base stations and terminals can be various forms of communication nodes, such as macro base stations, micro base stations, relay nodes, user equipment (UE), etc., or they can be referred to as downlink nodes and uplink nodes. In this embodiment, nodes using downlink channels to transmit downlink control information or downlink service information are collectively referred to as base stations, while nodes using uplink channels to transmit uplink control information or uplink service information are collectively referred to as terminals.

[0040] In 5G technology, dynamic scheduling-based time slot aggregation and scheduling-free time slot aggregation are introduced, allowing terminals to repeatedly transmit time-to-the-loop (TB) data in multiple time slots, with each TB having the same time-frequency resource allocation in each time slot. However, to support ultra-high reliability and ultra-low latency transmission, the same TB needs to be repeatedly transmitted multiple times on the resources after time slot aggregation. But for the terminal, the resources used to transmit uplink information are uplink resources. In the current radio frame structure, multiple symbols in a time slot may include uplink symbols, downlink symbols, and flexible symbols. The uplink information that the terminal needs to transmit can only use uplink symbols and some flexible symbols. When the uplink information that needs to be repeatedly transmitted encounters resources that cannot transmit uplink information, a collision will occur. At this point, it becomes impossible to determine the resources used for the repeated uplink transmission, which is a significant problem when applying repeated transmission to time slot aggregation. In this embodiment of the application, the information repeatedly transmitted by the terminal is taken as the Physical Uplink Shared Channel (PUSCH) as an example for illustration. However, the information repeatedly transmitted can also be other control channels, random access channels, and data channels, such as the Physical Downlink Shared Channel (PUSCH), Physical Uplink Control Channel (PUSCH), Physical Downlink Control Channel (PUSCH), Physical Random Access Channel (PRACH), etc.

[0041] Figure 1 A flowchart of a transmission resource configuration method provided in one embodiment is shown below. Figure 1 As shown, the method provided in this embodiment includes the following steps.

[0042] Step S1010: Receive transmission resource configuration information for repeatedly transmitting information to be transmitted. The transmission resource configuration information is used to indicate the starting symbol and the number of symbols for the duration of the first repeated transmission of information to be transmitted.

[0043] The transmission resource configuration method provided in this embodiment is applied to a terminal device in a mobile communication system, referred to as a terminal. The base station configures various transmission resources for both the base station and the terminal, and sends various configuration information to the terminal so that the base station and the terminal can determine the resources used for transmission and the various measurement or transmission commands to be executed. Various information sent from the base station to the terminal is transmitted through the downlink channel, while various information sent from the terminal to the base station is transmitted through the uplink channel. Regardless of the type of information transmitted between the base station and the terminal, both the base station and the terminal need to determine the transmission resources used by the information to be transmitted so that the base station and the terminal can complete the transmission and reception of the information on the determined transmission resources.

[0044] For a terminal, when it needs to repeatedly transmit information to be transmitted, or when it needs to receive information to be transmitted repeatedly transmitted by the base station, it first needs to determine the transmission resource configuration information for repeatedly transmitting the information to be transmitted. This transmission resource configuration information is configured by the base station; therefore, the terminal first needs to receive this information from the base station. This information indicates the start symbol and the duration (number of symbols) of the first repeated transmission. The terminal can then determine the transmission resources used for repeatedly transmitting the information based on this information.

[0045] The scheduling methods for resources used in information transmission between base stations and terminals can be divided into two types. One type requires the base station to explicitly indicate the available transmission resources using physical layer downlink control information (DCI), which is called dynamic scheduling. The other type requires the base station to explicitly indicate the available transmission resources using higher-layer signaling radio resource control (RRC) and / or DCI, which is called scheduling-free transmission. Regardless of whether it is dynamic scheduling or scheduling-free, when it is determined that the information to be transmitted needs to be repeatedly transmitted in the time domain, the terminal will receive transmission resource configuration information sent by the base station for repeatedly transmitting the information to be transmitted. The transmission resource configuration information is related to the start symbol and the number of symbols for the duration of the first repeated transmission of the information to be transmitted.

[0046] The transmission resource configuration information includes two different information combination methods. One method involves the transmission resource configuration information including a start symbol (S) and a time-domain duration symbol count (L). The start symbol (S) indicates the time-domain start position of the first repeated transmission of the information to be transmitted, and the time-domain duration symbol count (L) indicates the symbol length occupied by the information in the time domain during the first repeated transmission. The start symbol (S) and the time-domain duration symbol count (L) can be indicated independently, for example, occupying a total of 8 bits. The other method involves the transmission resource configuration information including a start symbol and a time-domain duration symbol count indicator value (SLIV). Parsing the SLIV yields the time-domain start symbol (S) and the time-domain duration symbol count (L) of the first repeated transmission of the information to be transmitted. Additionally, the base station also needs to determine the number of times (K) the information to be transmitted will be retransmitted.

[0047] Step S1020: Determine the transmission resources used for repeatedly sending the information to be transmitted based on the transmission resource configuration information.

[0048] After receiving the transmission resource configuration information for repeatedly transmitting information, the terminal also needs to determine the number of times the information will be repeatedly transmitted. This number is also indicated by the base station. Then, the terminal can determine the transmission resources used for repeatedly transmitting the information. Since the transmission resource configuration information includes the start symbol and the number of symbols for the time-domain duration of the first repeated transmission, the transmission resources used for the first repeated transmission are already determined. The time-domain duration of each repeated transmission should theoretically be the same as that of the first repeated transmission. Therefore, the transmission resources used for the second repeated transmission should theoretically start from the first symbol after the end symbol of the first repeated transmission. However, considering that different frame structures have different symbol configurations, multiple consecutive symbols with the same number of symbols for the time-domain duration as the first repeated transmission may not necessarily be able to transmit the information; that is, there may be symbol collisions. Therefore, it is necessary to determine the transmission resources used for each actual repeated transmission based on the symbol configuration in the actual frame structure. The transmission resources used for each repeated transmission need to skip symbols that cannot transmit the information.

[0049] The methods for determining the transmission resources used for repeatedly transmitting information based on transmission resource configuration information can be divided into two types, both based on the number of times the information to be transmitted is repeated (K) and the duration of the information to be transmitted in the first transmission (L). K*L yields the theoretical total symbol length required for repeatedly transmitting the information to be transmitted, which is the total symbol length required for repeatedly transmitting the information to be transmitted without considering symbols of non-transmittable information. However, due to the existence of symbols of non-transmittable information, the methods for determining the transmission resources used for repeatedly transmitting the information to be transmitted can be divided into two types: one is to determine the total symbol length of all repeatedly transmitted information based on the number of times the information to be transmitted is repeated and the duration of the time-domain symbols, including symbols of non-transmittable information; the other is to determine the total symbol length of repeatedly transmitted information based on the number of times the information to be transmitted is repeated and the duration of the time-domain symbols, excluding symbols of non-transmittable information. The specific method used can be configured by the base station, determined based on information such as the type of information to be transmitted, or preset in the system. These two different methods of determining transmission resources will be described in detail in the following embodiments.

[0050] Once the transmission resource configuration information for repeatedly transmitting the information to be transmitted is determined, the transmission resources used for this purpose can be identified. If the information to be transmitted is downlink information that the base station needs to send, the base station can send the information according to the determined transmission resources and send the transmission resource configuration information to the terminal, enabling the terminal to determine the transmission resources used by the base station for repeatedly transmitting the information. However, if the information to be transmitted is uplink information that the terminal needs to send, the base station needs to send the transmission resource configuration information to the terminal, enabling the terminal to determine the transmission resources used for repeatedly transmitting the information, and the base station also needs to determine the transmission resources used by the terminal for repeatedly transmitting the information based on the transmission resource configuration information.

[0051] The transmission resource configuration method provided in this embodiment, after receiving transmission resource configuration information for repeatedly transmitting information to be transmitted, uses the transmission resource configuration information to indicate the starting symbol and the number of symbols of the time domain duration for the first repeated transmission of information to be transmitted. Based on the transmission resource configuration information, the transmission resources used for repeatedly transmitting information to be transmitted are determined. Thus, when it is necessary to repeatedly transmit information to be transmitted, the transmission resources used for each transmission of information to be transmitted are determined, enabling the base station and the terminal to repeatedly transmit information on the determined transmission resources.

[0052] There are two ways to determine the transmission resources used for repeatedly transmitting information based on transmission resource configuration information: one is that the total symbol length includes symbols that cannot be transmitted, and the other is that the total symbol length does not include symbols that cannot be transmitted. The following detailed descriptions of these two methods use specific examples.

[0053] Figure 2 A flowchart of another transmission resource configuration method provided in one embodiment, such as Figure 2 As shown, the method provided in this embodiment includes the following steps.

[0054] Step S2010: Receive transmission resource configuration information for repeatedly transmitting information to be transmitted. The transmission resource configuration information is used to indicate the starting symbol and the number of symbols for the duration of the first repeated transmission of information to be transmitted.

[0055] Step S2020: Determine the total symbol length of all repeatedly transmitted information based on the number of times the information to be transmitted is repeated and the number of symbols in the time domain duration. The total symbol length includes symbols of information that cannot be transmitted.

[0056] The transmission resource configuration method provided in this embodiment is as follows: Figure 1 One possible implementation of the illustrated embodiment is as follows: In this embodiment, after determining the transmission resource configuration information for repeatedly transmitted information, the total symbol length of all repeatedly transmitted information is determined based on the number of times the information to be transmitted is repeatedly transmitted and the number of symbols with time-domain duration. The total symbol length includes symbols for information that cannot be transmitted. In this embodiment, the total symbol length includes symbols for information that cannot be transmitted; that is, the total symbol length is a nominal total symbol length, while the actual symbol length used to transmit the information is the actual number of symbols for which the information was transmitted.

[0057] Step S2030: Starting from the initial symbol, determine the transmission resources used for each repeated transmission of the information to be transmitted, wherein the sum of the number of symbols of the transmission resources used for repeated transmission of the information to be transmitted and the number of symbols of the information to be transmitted that cannot be transmitted is the total symbol length.

[0058] Once the total symbol length for all repeated transmissions of the information to be transmitted has been determined, the transmission resources used for each repeated transmission can be determined. Each repeated transmission requires skipping symbols on which the information to be transmitted cannot be transmitted, and transmitting the information on symbols on which the information to be transmitted can be transmitted. The sum of the number of symbols used for repeated transmissions of the information to be transmitted and the number of symbols on which the information to be transmitted cannot be transmitted equals the total symbol length.

[0059] In one embodiment, since the transmission resources used to send the information to be transmitted need to skip symbols that cannot transmit the information, the theoretically determined number of times the information to be transmitted is retransmitted may not be sufficient to complete the transmission each time. Therefore, the original number of retransmissions of the information to be transmitted can be used as the nominal number of retransmissions. The original number of retransmissions of the information to be transmitted is determined based on the retransmission requirements of the information to be transmitted. Each nominal retransmission of the information to be transmitted is continuous in the time domain, meaning that symbols that cannot transmit the information are included in the time domain symbols of the nominal retransmissions. Each nominal retransmission starts from the start symbol notified by the base station and proceeds sequentially according to the time domain duration symbol number. The actual number of times the resources to be transmitted are sent is called the actual number of retransmissions. Starting from the start symbol, symbols that cannot transmit the information are skipped, and the transmission resources used for each retransmission of the information to be transmitted are determined sequentially. The actual number of retransmissions can be the same as or different from the nominal number of retransmissions.

[0060] The transmission resource configuration method provided in this embodiment has different configurations of transmission resources used for each repeated transmission of information to be transmitted under different frame structure configurations. The following uses a specific configuration example to illustrate the transmission resource configuration method provided in this embodiment.

[0061] Figure 3 A schematic diagram of transmission resource configuration for one embodiment of a transmission resource configuration method is provided, as shown below. Figure 3 As shown, two time slots, time slot n and time slot n+1, are illustrated, each containing 14 symbols. For the transmission method with dynamically scheduled transmission resources, the frame structure is a semi-static frame structure, including symbols for downlink transmission (D symbols), symbols for uplink transmission (U symbols), and flexible symbols (F symbols). Assume the information to be transmitted is a PUSCH, with a nominal retransmission count of 4, and these 4 nominal retransmissions are consecutive in the time domain, meaning they are consecutive in available time slots. The first symbol of the PUSCH to be transmitted carries the Demodulation Reference Signal (DMRS), and the remaining symbols carry data. For the semi-static frame structure, starting from the start symbol, the transmission resources used for each retransmission of the information to be transmitted are determined sequentially, skipping symbols that cannot carry the information to be transmitted and guard interval symbols. Available time slots refer to those with sufficient UL symbols or flexible symbols, the number of which is greater than or equal to the number of symbols required to transmit one retransmission and guard interval.

[0062] The transmission resource configuration information indicates that the starting symbol of the first repeated PUSCH transmission is the 5th symbol of slot n, and the time-domain duration is 6 symbols. Here, the transmission resource configuration information indicating the first repeated PUSCH transmission refers to the first nominal repeated PUSCH transmission. Based on the 4 nominal repeated transmissions of the PUSCH, the total symbol length can be calculated to be 24 symbols, meaning the time-domain length of each nominal repeat is equal to 6 symbols. These 24 symbols include both transmittable and non-transmittable PUSCH symbols. Figure 3 The diagram shows the symbols corresponding to the four nominal retransmissions. From... Figure 3 As can be seen, the nominal repeat #1 transmission occupies the 5th to the 10th symbols of time slot n. Since these symbols are all F or U symbols, they can carry the required PUSCH transmission. In other words, the nominal repeat #1 transmission can complete the PUSCH transmission. The nominal repeat #1 transmission is actually the actual repeat #1.

[0063] Nominal repetition #2 occupies the 11th symbol of time slot n to the 2nd symbol of time slot n+1, crossing the time slot boundary. In this case, nominal repetition #2 is first divided into two repetitions according to the time slot boundary. That is, actual repetition #2 is the first repetition after the nominal repetition #2 is divided according to the time slot boundary. The transmission of actual repetition #2 occupies the 11th to the 14th symbols of time slot n, excluding non-transmittable symbols. Although actual repetition #2 only occupies 4 symbols, it can be made to carry the same PUSCH through rate matching or other methods. However, the 1st and 2nd symbols of time slot n+1 are D symbols and cannot transmit PUSCH. Therefore, the second repetition after the nominal repetition #2 is divided according to the time slot boundary cannot transmit PUSCH. The sum of the time domain lengths of the two repetitions after the nominal repetition #2 is divided according to the time slot boundary is equal to the time domain duration of nominal repetition #2.

[0064] Figure 3 This description focuses on specific resource allocation methods. In the transmission resource configuration method provided in this application embodiment, if the transmission resources used for the p-th nominal retransmission of the information to be transmitted cross a time slot boundary, the p-th nominal retransmission of the information to be transmitted is divided into two retransmissions based on the time slot boundary. Specifically, if the number of symbols for transmitting the information to be transmitted in either of the two retransmissions is less than a preset threshold, then the information to be transmitted cannot be transmitted; if the number of symbols for transmitting the information to be transmitted in either of the two retransmissions is greater than or equal to the preset threshold, then it is considered an actual retransmission. Here, p is an integer greater than or equal to 1. Figure 3The first and second symbols of time slot n+1 are D symbols, which cannot transmit PUSCH. Therefore, the second repetition of nominal repeat #2 after being divided according to the time slot boundary cannot transmit PUSCH. This preset threshold is, for example, the minimum number of symbols required to transmit PUSCH.

[0065] Nominal repetition #3 occupies the 3rd to 8th symbols of time slot n+1. The 3rd and 4th symbols of time slot n+1 are D and F symbols, respectively; the 5th to 7th symbols of time slot n+1 are F symbols; and the 8th symbol of time slot n+1 is a U symbol. Nominal repetition #3 does not cross time slot boundaries, but the 1st symbol of nominal repetition #3 is a D symbol and cannot transmit PUSCH. Although the 2nd symbol is an F symbol, a guard interval (gap) is required between uplink and downlink transmissions. In this embodiment, a guard interval of 1 symbol is used as an example. Therefore, the 2nd symbol of nominal repetition #3 will act as a guard interval and cannot transmit PUSCH. Thus, the last 4 symbols of nominal repetition #3 can transmit PUSCH. Therefore, the last 4 symbols of the nominal repeat #3 are used as the symbols occupied by the actual repeat #3. That is, if the number of symbols that can carry PUSCH is greater than the preset threshold, the actual repeat #3 can send PUSCH. Although the actual repeat #3 only occupies 4 symbols, it can carry the same PUSCH through rate matching and other methods.

[0066] Nominal repetition #4 occupies symbols 9 through 14 of time slot n+1, all of which are U symbols. Therefore, nominal repetition #4 can carry the required PUSCH transmission, meaning that nominal repetition #4 can complete the PUSCH transmission. Sending nominal repetition #4 is actually equivalent to actual repetition #4.

[0067] for Figure 3Nominal repetitions #1, #3, and #4 do not require segmentation since their transmission resources do not cross time slot boundaries. Furthermore, nominal repetitions #1 and #4 do not include symbols that cannot transmit PUSCH, so they are directly transmitted as actual repetitions #1 and #4, respectively. However, nominal repetition #3 contains symbols that cannot transmit PUSCH at its corresponding time-domain location. Therefore, these symbols must be skipped. In other words, nominal repetition #3 only uses symbols that can transmit PUSCH to carry the transmission of actual repetition #3. Thus, the length of transmission resources used for each actual repetition transmission is less than or equal to the length of transmission resources used for the corresponding nominal repetition, meaning the length of transmission resources used for each actual repetition transmission is less than or equal to the number of symbols corresponding to the time-domain duration of the nominal repetition transmission. In other words, if the transmission resources used for the j-th nominal retransmission of the information to be transmitted do not cross time slot boundaries, then the j-th nominal retransmission is treated as the k-th actual retransmission, and the length of the transmission resources used for the k-th actual retransmission of the information to be transmitted is less than or equal to the number of symbols of the time-domain duration corresponding to the j-th nominal retransmission, where j and k are integers greater than or equal to 1. The transmission resources used for the j-th nominal retransmission of the information to be transmitted can include non-transmittable symbols, while the transmission resources used for the k-th actual retransmission of the information to be transmitted do not include non-transmittable symbols. That is, the symbols used for the actual transmission of the information to be transmitted only include symbols that can transmit the information, and none of them are considered isolated symbols. Therefore... Figure 3 In the configuration shown, there are a total of 4 actual repetitions: actual repetition #1, actual repetition #2, actual repetition #3 and actual repetition #4 sent PUSCH, and a total of 20 valid symbols were used for PUSCH transmission.

[0068] Figure 3 The frame structure in the text is a semi-static frame structure. In addition, the frame structure also includes a dynamic frame structure, which means that some F symbols can be reconfigured into symbol types for other transmission directions. Therefore, it is necessary to determine whether the F symbol is indicated as a symbol that cannot transmit the information to be transmitted.

[0069] Figure 4 A schematic diagram of transmission resource configuration for another transmission resource configuration method provided in one embodiment, as shown below. Figure 4 As shown, two time slots, time slot n and time slot n+1, are displayed, each containing 14 symbols. For the transmission mode of scheduling-free transmission resources, when the frame structure is a semi-static frame structure, the resource configuration method for repeated transmission is the same as... Figure 3The process is the same. However, if the frame structure is dynamic, assuming the information to be transmitted is PUSCH, the nominal number of retransmissions is 4. The first symbol of the PUSCH to be transmitted carries DMRS, and the remaining symbols carry data. For dynamic frame structures, starting from the start symbol, the transmission resources used for each retransmission of the information to be transmitted are determined sequentially, skipping symbols that cannot carry information to be transmitted, flexible symbols indicated as not carrying information to be transmitted, downlink symbols, and guard interval symbols. The following explains the retransmission resource configuration for PUSCH in the case of dynamic frame structures.

[0070] The transmission resource configuration information indicates that the starting symbol of the first repeated PUSCH transmission is the 5th symbol of time slot n, and the time-domain duration is 6 symbols. Here, the transmission resource configuration information indicating the first repeated PUSCH transmission refers to the first nominal repeated PUSCH transmission. Therefore, based on the 4 nominal repeated PUSCH transmissions, the total symbol length can be calculated to be 24 symbols. These 24 symbols include both transmittable and non-transmittable PUSCH symbols. Figure 4 The diagram shows the symbols corresponding to the four nominal retransmissions. From... Figure 4 As can be seen, nominal repetition #1 occupies the 5th to the 10th symbols of time slot n. Since these symbols are all F or U symbols, they can carry the required PUSCH. In other words, nominal repetition #1 can complete the PUSCH transmission. Nominal repetition #1 is actually actual repetition #1.

[0071] Nominal repetition #2 occupies the space from the 11th symbol of time slot n to the 2nd symbol of time slot n+1, crossing the time slot boundary. In this case, nominal repetition #2 is first divided into two repetitions according to the time slot boundary. For example... Figure 4 As shown, actual repetition #2 is the first repetition of the two repetitions mentioned above. The transmission of actual repetition #2 occupies symbols 11 to 14 of time slot n, excluding untransmittable symbols. Although actual repetition #2 only occupies 4 symbols, it can be made to carry the same PUSCH through rate matching or other methods. However, the first and second symbols of time slot n+1 are D symbols, which cannot transmit PUSCH. Therefore, the second repetition of nominal repetition #2 after time slot division cannot transmit PUSCH. That is, the number of symbols that can carry PUSCH is less than a preset threshold, which is, for example, the minimum number of symbols required to transmit PUSCH. The sum of the time domain lengths of the two repetitions of nominal repetition #2 after time slot boundary division is equal to the time domain duration of nominal repetition #2.

[0072] Nominal repeat #3 occupies symbols 3 through 8 of time slot n+1. Symbol 3 of time slot n+1 is a D symbol, symbols 4 through 7 of time slot n+1 are F symbols, and symbol 8 of time slot n+1 is a U symbol. Symbols 4 through 6 of time slot n+1, although F symbols, are indicated by the Slot Format Indicator (SFI) as symbols for transmitting downlink information, effectively becoming D symbols. Therefore, nominal repeat #3 does not cross time slot boundaries, but its first symbol (D symbol) cannot send PUSCH, and symbols 2 through 4 (indicated by the SFI as symbols for transmitting downlink information) also cannot send PUSCH. Although the fifth symbol is an F symbol, a guard interval (gap) is required between uplink and downlink transmissions. In this embodiment, a guard interval of one symbol is used as an example; therefore, the fifth symbol of nominal repeat #3 will act as a guard interval and cannot send PUSCH. Therefore, nominal repeat #3 can only send PUSCH on the last symbol, but this symbol is an isolated symbol and cannot carry the required PUSCH. Thus, nominal repeat #3 cannot complete the PUSCH transmission, and PUSCH cannot be sent on any of the time-domain symbols corresponding to nominal repeat #3.

[0073] Nominal repetition #4 occupies symbols 9 through 14 of time slot n+1, all of which are U symbols. Therefore, nominal repetition #4 can carry the required PUSCH transmission; that is, nominal repetition #4 can complete the PUSCH transmission. Nominal repetition #4 is actually actual repetition #3. In other words, the symbols for actually transmitting information only include those capable of transmitting the information, and none are considered isolated symbols. Figure 4 In the configuration shown, there are three actual repetitions: actual repetition #1, actual repetition #2, and actual repetition #3, using a total of 16 valid symbols for PUSCH transmission.

[0075] Step S5010: Receive transmission resource configuration information for repeatedly transmitting information to be transmitted. The transmission resource configuration information is used to indicate the starting symbol and the number of symbols for the duration of the first repeated transmission of information to be transmitted.

[0076] Step S5020: Determine the total symbol length of the repeatedly transmitted information based on the number of times the information to be transmitted is repeatedly sent and the number of symbols with time domain duration. The total symbol length does not include symbols of information that cannot be transmitted.

[0077] The transmission resource configuration method provided in this embodiment is as follows: Figure 1 In one possible implementation of the illustrated embodiment, after determining the transmission resource configuration information for repeatedly transmitting the information to be transmitted, the total symbol length for repeatedly transmitting the information to be transmitted is determined based on the number of times the information to be transmitted is repeatedly transmitted and the number of symbols with time-domain duration. The total symbol length does not include symbols for information that cannot be transmitted. In this embodiment, the total symbol length does not include symbols for information that cannot be transmitted; that is, the total symbol length is the actual total symbol length.

[0078] Step S5030: Starting from the initial symbol, determine the transmission resources used for each repeated transmission of the information to be transmitted, wherein the number of symbols used for the transmission resources for each repeated transmission of the information to be transmitted is the total symbol length.

[0079] Once the total symbol length for repeatedly transmitting the information has been determined, the transmission resources used for each repeated transmission can be determined. The transmission resources used for the first transmission are the number of symbols lasting in the time domain, starting from the initial symbol. From the second transmission onwards, if a symbol that cannot be transmitted is encountered, transmission will be delayed until the symbol immediately following that symbol. The number of symbols used for the transmission resources in repeated transmissions is the total symbol length.

[0080] Figure 6 A schematic diagram of transmission resource configuration for another transmission resource configuration method provided in one embodiment, as shown below. Figure 6 As shown,

[0081] Two time slots, time slot n and time slot n+1, are shown, each containing 14 symbols. The frame structure can be a semi-static frame structure or a dynamic frame structure. Assume the information to be transmitted is PUSCH, and it is repeated twice. The transmission resource configuration information indicates that the starting symbol of repetition #1 is the 5th symbol of time slot n, and the time domain duration is 6 symbols. Therefore, repetition #1 occupies the 5th to 10th symbols of time slot n. Since these symbols are all F or U symbols, they can carry the required PUSCH transmission. Repetition #2 starts from the 11th symbol of time slot n and ends at the 14th symbol of time slot n. The next symbol, the 1st symbol of time slot n+1, is a D symbol, which cannot transmit PUSCH. Therefore, it is delayed until the first symbol after the 14th symbol of time slot n where PUSCH can be transmitted. The period from the 11th to the 14th symbol of time slot n includes 4 symbols, which can be used to transmit PUSCH through rate matching, thus repetition #2 is performed. However, at this point, repetitions #1 and #2 together occupy 10 symbols, which does not reach the total symbol length determined by the transmission resource configuration information. Therefore, two more symbols need to be selected from the delayed available symbols for repetition #3. Figure 6 In the semi-static frame structure, since the 1st, 2nd, and 3rd symbols of time slot n+1 are D symbols, and the 4th symbol of time slot n+1 needs to be used as a guard interval, PUSCH cannot be transmitted. Therefore, the 5th and 6th symbols of time slot n+1 can be used as transmission resources for repetition #3. Although there are only 2 symbols, PUSCH can still be transmitted through rate matching, i.e., repetition #3 is performed. Figure 5 In the dynamic frame structure shown, since the 4th and 5th symbols of time slot n+1 are both indicated by SFI as downlink transmission, and the 6th symbol needs to be used as a guard interval, the 7th and 8th symbols of time slot n+1 can be used as transmission resources for repeating #3. Therefore... Figure 6 In the configuration shown, there are 3 repeated transmissions, and a total of 12 valid symbols are used for PUSCH transmission.

[0082] for Figure 5 The illustrated embodiment, which excludes symbols that cannot be transmitted from the total symbol length of the transmission resources used for repeatedly sending the information to be transmitted, also determines the time window occupied by the transmission resources used for repeatedly sending the information to be transmitted in the time domain. The time window represents the transmission window in the time domain for the transmission resources used to send the information to be transmitted, including the start and end points of the time window; transmission stops when the time window is exceeded. Since the transmission resource configuration information already indicates the starting symbol for the first repeated transmission of the information to be transmitted, the time window should also include the ending symbol for the repeated transmission of the information to be transmitted.

[0083] The time window is determined by the base station. The terminal receives time-frequency resource information indicating the time window sent by the base station via RRC signaling or DCI signaling. The time-frequency resource information indicating the time window may include any combination of the following combinations one to six:

[0084] Combination 1: The time slot index for the first repeated transmission of the information to be transmitted, the starting symbol for the first repeated transmission of the information to be transmitted, the time domain duration symbol count for the first repeated transmission of the information to be transmitted, the time slot index for the end of the repeated transmission of the information to be transmitted, and the symbol index.

[0085] Combination 2: The time slot index for the first repeated transmission of the information to be transmitted, the starting symbol for the first repeated transmission of the information to be transmitted, the time domain duration symbol count for the first repeated transmission of the information to be transmitted, and the time slot index for the end of the repeated transmission of the information to be transmitted.

[0086] Combination 3: The time slot index of the first repeated transmission of the information to be transmitted, the starting symbol of the first repeated transmission of the information to be transmitted, the number of symbols for the time domain duration of the first repeated transmission of the information to be transmitted, and the symbol index of the end of the repeated transmission of the information to be transmitted.

[0087] Combination 4: The first SLIV to be transmitted, the slot index for the end of the SLIV to be transmitted, and the symbol index.

[0088] Combination 5: The first SLIV to be repeatedly sent and the slot index to end the repeated sending of the information to be transmitted.

[0089] Combination 6: First retransmission of the SLIV message to be transmitted, followed by the symbol index to end the retransmission of the SLIV message to be transmitted.

[0090] In one embodiment, in combination one or combination four, the time slot index for ending repeated transmission of information to be transmitted is the specific time slot position, and does not limit the specific end symbol position, because there is also a symbol index to indicate the specific end symbol position.

[0091] In one embodiment, in combination two or five, the time slot index for ending repeated transmission of information to be transmitted is used to indicate that the resources used for the last repeated transmission of information to be transmitted cannot exceed the last symbol of the time slot index for ending repeated transmission of information to be transmitted. For example, if the time slot for ending repeated transmission of information to be transmitted includes 14 symbols, then the repeated transmission of information to be transmitted ends before the 14th symbol of the time slot, including the 14th symbol.

[0092] In one embodiment, in combination three or combination six, the symbol index for ending repeated transmission of the information to be transmitted is used to indicate the total number of available symbols for repeated transmission of the information to be transmitted, excluding symbols for which the information to be transmitted cannot be transmitted. For example, if the symbol index for ending repeated transmission of the information to be transmitted is 30 symbols, then it indicates that the total length of the information to be transmitted repeatedly is 30 symbols, including symbols for which the information to be transmitted cannot be transmitted.

[0093] In one embodiment, the time window is determined by the base station. The terminal receives the time window sent by the base station via RRC signaling or DCI signaling. In other words, the time window can be independently indicated by either RRC or DCI signaling. The indication method can be any of the following: Method 1: A new field is introduced in the RRC signaling to indicate the time window, and enabling or disabling this field indicates whether the time window is being notified. Method 2: A new field is introduced in the DCI signaling to indicate the time window, or existing fields in the DCI signaling, such as Redundancy Version (RV), Hybrid Automatic Repeat Request Identity (HARQ ID), or New Data Indicator (NDI) fields, are reused to send the time window.

[0094] In one embodiment, the time window occupied by the transmission resources used for repeatedly transmitting the information to be transmitted in the time domain is only used for the repeated transmission of the information to be transmitted without scheduling. Taking the information to be transmitted as PUSCH as an example, the slot index of the first repeated transmission is determined according to the timing (slot offset K2). The slot index of the end position is the specific slot index of the last transmitted PUSCH, and the symbol index of the end position is the specific symbol index of the PUSCHs transmitted sequentially from left to right. As shown in Table 1, when the row index is equal to 1, the slot index of the end position is equal to 2, indicating that the slot index of the end position is slot2, and the symbol index of the end position is equal to 4, indicating that the symbol index of the end position is symbol 4.

[0095] Table 1

[0096]

[0097] In one embodiment, the slot index of the end position can also be a time-domain slot offset relative to the slot index of the first repeated transmission. For example, in Table 1, when the row index is equal to 1, the slot index of the end position being equal to 2 means that the slot index of the end position is (K2) + 2 of the slot index of the first repeated transmission. For example, if the first repeated transmission is in slot 1, then the slot index of the end position is 1 + 2 = 3, that is, in slot 3. Similarly, the symbol index of the end position can also be an offset relative to the symbol index of the start or end position of the first repeated transmission.

[0098] The time-domain resource information in Table 1 is jointly indicated by layer configuration and higher-level signaling, or it can be jointly indicated by higher-level configuration and dynamic control signaling. It should be noted that the time-domain resource allocation parameters configured by higher levels can also include other control domains, which will not be elaborated here.

[0099] Figure 2 and Figure 5 The diagram illustrates two methods for determining the transmission resources used to repeatedly transmit information based on transmission resource configuration information. Method one involves a total symbol length that includes symbols that cannot transmit the information to be transmitted; method two involves a total symbol length that does not include symbols that cannot transmit the information to be transmitted. The specific transmission method used for transmitting the information to be transmitted needs to be determined by the base station through interaction with the terminal. The base station and the terminal can determine the transmission method using any of the following three methods.

[0100] Method 1: The terminal receives transmission resource configuration information sent by the base station via RRC signaling or DCI signaling. The transmission resource configuration information includes a transmission mode indication, which includes: an indication of the total number of symbols to be repeatedly transmitted, including symbols that cannot be transmitted, or an indication of the total number of symbols to be repeatedly transmitted, excluding symbols that cannot be transmitted.

[0101] The transmission resource configuration information includes any one of the following combinations:

[0102] Combination Method 1: The time slot index of the first repeated transmission of the information to be transmitted, the start symbol of the first repeated transmission of the information to be transmitted, the number of symbols for the time domain duration of the first repeated transmission of the information to be transmitted, and the transmission mode indicator.

[0103] Combination Method 2: The first time, the SLIV of the information to be transmitted and the transmission method indication are sent repeatedly.

[0104] Combination Method 3: The time slot index of the first repeated transmission of the information to be transmitted, the start symbol of the first repeated transmission of the information to be transmitted, and the number of symbols in the time domain duration of the first repeated transmission of the information to be transmitted are specified. The transmission mode indication is determined based on the size of the number of symbols in the time domain duration. For example, if the number of symbols in the time domain duration is less than or equal to a certain value or threshold, transmission method 1 is used; if the number of symbols in the time domain duration is greater than a certain value or threshold, transmission method 2 is used, and vice versa. The specified value or threshold is notified by RRC signaling or DCI signaling.

[0105] Combination Method Four: The time slot index of the first repeated transmission of the information to be transmitted, the starting symbol of the first repeated transmission of the information to be transmitted, the number of symbols for the time domain duration of the first repeated transmission of the information to be transmitted, the transmission type of the information to be transmitted, and the transmission mode indicator are determined according to the transmission type of the information to be transmitted. Taking the information to be transmitted as PUSCH as an example, when the PUSCH mapping type is type A, transmission method one is used; when the PUSCH mapping type is type B, transmission method two is used, and vice versa. The main difference between type A and type B is that the starting symbol position and the time domain duration have different requirements. For example, PUSCH mapping type A means that the starting symbol can only start from the first symbol of a certain time slot, and the time domain duration is at least 4 symbols; PUSCH mapping type B means that the starting symbol can start from any symbol of a certain time slot, and the time domain duration can be at least 1 symbol.

[0106] Combination Method 5: The SLIV of the information to be transmitted is sent repeatedly for the first time. The transmission method is determined based on the value of the SLIV. For example, when the value of the SLIV is less than or equal to a certain value or threshold, transmission method one is used; when the value of the SLIV is greater than a certain value or threshold, transmission method two is used, and vice versa. The certain value or threshold is notified by RRC signaling or DCI signaling.

[0107] Taking the information to be transmitted as PUSCH as an example, the slot index for the first repeated transmission is determined by the timing (slotoffset K2). As shown in Table 2, when the row index is equal to 1, the mode indicator is 1, indicating that transmission mode one is used; when the mode indicator is 0, it means that this parameter cannot be used, which means that transmission mode two is used. Alternatively, the mode indicator 1 can indicate that transmission mode two is used, while the mode indicator 0 indicates that transmission mode one is used.

[0108] Table 2

[0109]

[0110] Method 2: Receive the transmission mode indication sent by the base station via RRC signaling or DCI signaling. The transmission mode indication includes: an indication of the total number of symbols to be repeatedly transmitted, including symbols that cannot be transmitted, or an indication of the total number of symbols to be repeatedly transmitted, excluding symbols that cannot be transmitted. For example, an RRC signaling choice structure can be used to select a mode, or to enable or disable mode 1. If the RRC parameters are not configured, mode 1 is used by default, which is either transmission mode 1 or transmission mode 2.

[0111] Method 3: Determine the transmission mode indication based on the transmission type of the information to be transmitted. Specifically, when the transmission type is dynamic scheduling-based, the total symbol length of the repeatedly transmitted information in the transmission mode indication includes symbols of information that cannot be transmitted; when the transmission type is scheduling-free, the total symbol length of the repeatedly transmitted information in the transmission mode indication does not include symbols of information that cannot be transmitted. Alternatively, the opposite indication method can be used: when the transmission type is dynamic scheduling-based, the total symbol length of the repeatedly transmitted information in the transmission mode indication does not include symbols of information that cannot be transmitted; when the transmission type is scheduling-free, the total symbol length of the repeatedly transmitted information in the transmission mode indication includes symbols of information that cannot be transmitted.

[0112] Figure 7 A flowchart of another transmission resource configuration method provided in one embodiment, such as Figure 7 As shown, the method provided in this embodiment includes the following steps.

[0113] Step S7010: Determine the transmission resource configuration information for repeatedly transmitting the information to be transmitted. The transmission resource configuration information is used to indicate the starting symbol and the number of symbols for the duration of the first repeated transmission of the information to be transmitted.

[0114] Step S7020: Determine the transmission resources used for repeatedly sending the information to be transmitted based on the transmission resource configuration information.

[0115] The transmission resource configuration method provided in this embodiment is applied to base station equipment in a mobile communication system, referred to as a base station. The base station configures various transmission resources for both the base station and the terminal, and sends various configuration information to the terminal, enabling the base station and the terminal to determine the resources used for transmission and the various measurement or transmission commands to be executed. Information sent from the base station to the terminal is transmitted through the downlink channel, while information sent from the terminal to the base station is transmitted through the uplink channel. Regardless of the type of information transmitted between the base station and the terminal, both the base station and the terminal need to determine the transmission resources used by the information to be transmitted, so that the base station and the terminal can complete the transmission and reception of the information on the determined transmission resources.

[0116] For a base station, when it needs to repeatedly transmit information to be transmitted, or when it needs to receive information to be transmitted repeatedly transmitted by the base station, it first needs to determine the transmission resource configuration information for repeatedly transmitting the information to be transmitted. This transmission resource configuration information is configured by the base station and indicates the starting symbol and the duration (number of symbols) of the first repeated transmission of the information to be transmitted. The base station can then determine the transmission resources used for repeatedly transmitting the information to be transmitted based on this configuration information.

[0117] The specific processing method of the transmission resource configuration method provided in this embodiment is the same as... Figure 1 The transmission resource configuration methods shown are similar, the only difference being... Figure 1 In the illustrated embodiment, the transmission resource configuration information for repeatedly transmitting information to be transmitted is received by the terminal from the base station. However, in this embodiment, the transmission resource configuration information for repeatedly transmitting information to be transmitted is configured by the base station itself. The specific configuration method for the transmission resource configuration information and the method for determining transmission resources based on the transmission resource configuration information are detailed in [the following section]. Figure 1 The embodiments shown have been described in detail and will not be repeated here.

[0118] Furthermore, since there are two ways to determine the transmission resources used for repeatedly transmitting information based on transmission resource configuration information, and transmission resource configuration information also includes two different information combination methods, the base station side can also implement, for example... Figures 2-6 The transmission resource configuration method shown in any embodiment differs only in that Figures 2-6 The illustrated embodiment is processed by the terminal, while in this embodiment it is processed by the base station. Figures 2-6 In the illustrated embodiment, the various information sent by the base station to the terminal is replaced by the corresponding information sent by the base station to the terminal. However, the specific structure of each type of information and the processing performed based on each type of information are the same, and will not be described again here.
