[0002] Currently, time domain resource allocation of a Physical Uplink Shared Channel (PUSCH) may use a time domain resource allocation (TDRA) table such as PUSCH repetition type B or PUSCH repetition type A. When the PUSCH transmission method is transmission of transport blocks over multiple slots (TB Processing Over Multi-slots, TBoMS), one transport block is simultaneously transmitted in multiple time slots, and therefore the conventional TDRA table for PUSCH repetition type B or PUSCH repetition type A cannot be simultaneously applied to the time domain resource allocation method of TBoMS to perform time domain resource allocation.

[0003] Therefore, there is a need for a time domain resource allocation method in which the TDRA table can be applied to the time domain resource allocation method of TBoMS to perform time domain resource allocation, and at the same time, can be applied to multiple time domain resource allocation methods to perform time domain resource allocation.

[0068] To facilitate understanding, terms used in this disclosure will first be explained.

Physical uplink shared channel (PUSCH) The PUSCH is used to carry uplink services and upper layer signaling data related to long-term evolution users. As the main uplink data carrier channel of the physical layer, it can schedule and transmit uplink data and can also carry control information.

[0070] To better understand the time domain resource allocation method disclosed in the embodiments of the present disclosure, the following first describes a communication system to which the embodiments of the present disclosure are applied.

[0071] Referring to Figure 1, Figure 1 is a schematic diagram of the architecture of a communication system 10 provided by an embodiment of the present disclosure. The communication system 10 may include, but is not limited to, one network device 11 and one terminal device 12. The number and form of devices shown in Figure 1 are exemplary and do not limit the embodiment of the present disclosure. In actual applications, the communication system 10 may include two or more network devices 11 and two or more terminal devices 12. For example, the communication system 10 shown in Figure 1 includes one network device 11 and one terminal device 12.

[0072] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a long term evolution (LTE) system, a fifth generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems.

[0073] The network device 11 in the embodiments of the present disclosure is a network-side entity for transmitting and receiving signals. For example, the network device 11 may be an evolved base station (eNB), a transmission reception point (TRP), a next-generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and device form used by the network device. The network device 11 provided by the embodiments of the present disclosure may be configured with a central unit (CU) and distributed units (DUs), where the CU may also be referred to as a control unit. The CU-DU structure may be used to separate protocol layers of a network device, for example, a base station, with some protocol layer functions centrally controlled in the CU and some or all of the remaining protocol layer functions distributed to the DUs, and the DUs centrally controlled by the CU.

[0074] The terminal device 12 in the embodiments of the present disclosure is a user-side entity for transmitting and receiving signals, such as a mobile phone. The terminal device may also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet, a computer with wireless transmission and reception capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure are not limited by the specific technology and device form used by the terminal device 12.

[0075] In related technology, Type B PUSCH repetition, i.e., a PUSCH repetition transmission scheme based on sub-timeslot aggregation, can improve the reliability of PUSCH transmission and further reduce transmission delay. For Type B PUSCH repetition, uplink grant signaling or Type 1 license-free configuration information indicates the resource of the first nominal PUSCH, and the time domain resource of the remaining PUSCH repetitions depends on the first PUSCH repetition and available symbols. The number of repeated transmissions indicated by the base station represents the nominal repetition number, and the actual repetition number may be greater than the nominal repetition number. If the time domain resource of the nominal PUSCH crosses a timeslot boundary, it is divided into two actual PUSCH transmissions. A column indicating the number of PUSCH repetitions is added to the time domain resource allocation (TDRA) table, and the possible values ​​may be {1, 2, 3, 4, 7, 8, 12, 16}. At the same time, the RRC higher layer signaling indicates the start time domain position S and the data transmission length L by 4 bits each, where 0<=S<=13, 1<=L<=14, and S+L>14 can be realized.

[0076] TDRA for Type A Repetition: The first solution for transmitting uplink data multiple times is also called repetition of uplink data packets, or repeated transmission, aggregation, or aggregation transmission. The number of times the same uplink data packet is transmitted is also called the repetition number or aggregation factor. The TDRA table includes a start and length indicator value (SLIV) field for determining the start time domain position S of each transmission and the length L of data transmission, as well as a repetition number field for determining the number N of blind retransmissions. The blind retransmissions are performed within N adjacent time slots, with one complete repetition performed within one time slot, and the symbol position for blind retransmissions within each time slot is the same.

[0077] TDRA for TBoMS: For time domain resource allocation in TBoMS, time domain resource allocation (TDRA) using PUSCH repetition type A-like or PUSCH repetition type B-like may be used. For type B-like schemes, related art proposes extending the data transmission length L to greater than 14 symbols, and the time domain symbol length required for TBoMS can be determined using only the L field. Since TBoMS does not have a concept related to repetition, type A-like or type B-like TDRA cannot directly use the time domain allocation method provided by the embodiments of the present disclosure. However, application to TBoMS mode is possible by redefining some fields in the TDRA table, such as the Repetition Number field / L field.

[0078] It should be noted that the communication systems described in the embodiments of the present disclosure are intended to more clearly explain the technical solutions of the embodiments of the present disclosure, and do not limit the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will recognize that with the evolution of system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure can be similarly applied to similar technical issues.

[0079] The time domain resource allocation method and apparatus provided by the present disclosure will be described in detail below in conjunction with the accompanying drawings.

[0080] Referring to Figure 2, Figure 2 is a schematic flowchart of a time domain resource allocation method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Figure 2, the method may include, but is not limited to, the following steps S1 to S2:

[0081] In S1, a time domain resource allocation (TDRA) table is obtained, and the TDRA table includes a first field and a second field corresponding to the first field.

[0082] In an embodiment of the present disclosure, the obtained time domain resource allocation (TDRA) table may be a TDRA table for PUSCH repetition type A or type B having specific defined fields, which may be existing fields in a conventional TDRA table for PUSCH repetition type A or type B, or may be additional fields.

[0083] Alternatively, in an embodiment of the present disclosure, the obtained time domain resource allocation (TDRA) table may be a TDRA table for conventional PUSCH repetition type A or type B. The present disclosure is not limited thereto.

[0084] Here, a first field contained in the TDRA table is obtained, and in some embodiments, the first field is carried by the L field in the TDRA table, which can determine the length of the data transmission.

[0085] In embodiments of the present disclosure, a second field corresponding to the first field is obtained based on the obtained first field, and in some embodiments, the second field is carried by a Repetition Number field in the TDRA table, which can determine the number of repetitions of data transmission.

[0086] In S2, time domain resource allocation is performed based on the first and second fields.

[0087] In the embodiment of the present disclosure, the length of data transmission is determined based on the first field, and the number of repetitions of data transmission is determined based on the second field, thereby determining the time domain resource allocation method, so that the corresponding time domain resource allocation method can perform time domain resource allocation according to the corresponding time domain resource allocation method.

[0088] By implementing the embodiments of the present disclosure, a time domain resource allocation (TDRA) table is obtained, a first field included in the TDRA table is obtained, a second field corresponding to the first field is obtained, and time domain resource allocation is performed based on the first field and the second field, so that the TDRA table can be applied to time domain resource allocation of a corresponding time domain resource allocation scheme.

[0089] In some embodiments, as shown in FIG. 3, in the embodiments of the present disclosure, the above S2 further includes the following S21A to S21B:

[0090] In S21A, the number of valid rows in the TDRA table is determined based on the time domain resource allocation method.

[0091] In S21B, time domain resource allocation is performed based on the first field, the second field, and the number of valid rows in the TDRA table.

[0092] Here, the time domain resource allocation schemes include a transmission block over multiple slots (TBoMS) scheme, a repetition scheme, and a TBoMS scheme with repetition.

[0093] For the repetition transmission method, only rows in the TDRA table where the L field is ≦14 symbols are valid.

[0094] For transmission of a transmission block over multiple slots (TBoMS), in the TDRA table, rows where the L field > 14 symbols are valid and rows where the repetition number > 1 symbol are invalid.

[0095] For the TBoMS system with repetitive transmission, all rows in the table where the L field > 14 symbols and the repetition number > 1 symbol are invalid.

[0096] In some embodiments, as shown in FIG. 4, S2 in the embodiments of the present disclosure further includes the following S21 to S22:

[0097] In S21, a time domain resource allocation method is obtained.

[0098] In S22, time domain resource allocation is performed based on the first field, the second field, and the time domain resource allocation scheme.

[0099] In some embodiments of the present disclosure, the time domain resource allocation scheme includes at least one of a transmission block over multiple slots (TBoMS) scheme, a repetition scheme, and a TBoMS scheme with repetition.

[0100] In addition, in the embodiments of the present disclosure, the time domain resource allocation method may be a transmission of transmission blocks over multiple slots (TBoMS) method, or a repetition transmission method, or a TBoMS method with repetition transmission, or a transmission of transmission blocks over multiple slots (TBoMS) method and a repetition transmission method, or any combination of the three.

[0101] Here, the repetition transmission scheme is as follows: In a 5G communication system, a transmitter can repeatedly transmit the same data in the time domain, thereby improving the reliability of data transmission by utilizing time-domain diversity gain due to channel variations in the time domain and hybrid automatic repeat request (HARQ) combining gain. For example, a terminal can transmit different redundancy versions (RVs) of the same transport block (TB) in multiple time units, where one RV of the TB is transmitted in one time unit and the TB is transmitted by one transmission layer. The base station combines and decodes the data received in the multiple time units to improve the success rate of data reception and the reliability of data transmission. A multi-slot transmission of transport blocks (TBoMS) scheme refers to the transmission of one transport block of a PUSCH in multiple time slots, and there is no overlapping concept involved. A TBoMS scheme with repetition transmission can be understood as a TBoMS scheme with a repetition transmission function.

[0102] In some embodiments, as shown in FIG. 5, S21 of the method in the embodiments of the present disclosure further includes S211A to S212A.

[0103] In S211A, the first symbol length of the first field and the second symbol length of the second field are acquired.

[0104] Specifically, in the embodiment of the present disclosure, if the first field is an L field, the length of the first symbol carried by the L field is the length L of the data transmission, and if the second field is a Repetition Number field, the length of the second symbol carried by the Repetition Number field is the number of repetition transmissions.

[0105] In S212A, a time domain resource allocation method is determined based on the first symbol length and the second symbol length.

[0106] For example, if the data transmission length L>14 and the repetition number>1, it is determined that the time domain resource allocation scheme is the TBoMS scheme with repetitive transmission.

[0107] If the data transmission length L>14 and the repetition number≦1, it is determined that the time domain resource allocation method is the transmission block over multiple slots (TBoMS) method.

[0108] If the data transmission length L<14 and the repetition number>1, it is determined that the time domain resource allocation method is the repetition method.

[0109] In the embodiment of the present disclosure, the first symbol length of the first field and the second symbol length of the second field can be obtained to determine the manner of time domain resource allocation.

[0110] In some other embodiments, as shown in FIG. 6, S21 of the method in the embodiments of the present disclosure further includes S211B to S212B.

[0111] In S211B, the length of the first symbol in the first field is obtained.

[0112] In S212B, a time domain resource allocation method is determined based on the first symbol length.

[0113] Specifically, in the embodiment of the present disclosure, if the first field is an L field, the length of the first symbol carried by the L field is the length L of the data transmission.

[0114] For example, if the data transmission length L<14, it is determined that the time domain resource allocation method is a repetition transmission method, and if the data transmission length L>14, it is determined that the time domain resource allocation method is a transmission block over multiple slots (TBoMS) method or a TBoMS method with repetition transmission.

[0115] In some other embodiments, as shown in FIG. 7, S21 of the method in the embodiments of the present disclosure further includes the following S211C to S212C.

[0116] In S211C, the first configuration signaling is received.

[0117] In some embodiments, the first configuration signaling in embodiments of the present disclosure includes remaining minimum system information (RMSI) signaling, Radio Resource Control (RRC) signaling, downlink control information (DCI) signaling, or media access control element (MAC CE) signaling.

[0118] In S212C, a time domain resource allocation method is determined based on the first configuration signaling.

[0119] Here, the first configuration signaling can determine that the corresponding time domain resource allocation scheme is one of a transmission block over multiple slots (TBoMS) scheme, a repetition transmission scheme, and a TBoMS scheme with repetition transmission.

[0120] In some embodiments, Residual Minimum System Information (RMSI) signaling or Radio Resource Control (RRC) signaling can determine that the time domain resource allocation scheme is one of a transmission block over multiple slots (TBoMS) scheme, a repetition scheme and a TBoMS scheme with repetition, or can determine that the time domain resource allocation scheme is one of a transmission block over multiple slots (TBoMS) scheme and a repetition scheme. Downlink Control Information (DCI) signaling or Media Access Control Control Element (MAC CE) signaling can determine that the time domain resource allocation scheme is one of a transmission block over multiple slots (TBoMS) scheme and a repetition scheme.

[0121] Determining the corresponding time domain resource allocation scheme based on the first configuration signaling can be understood as directly determining different time domain resource allocation schemes based on the differences in the content of the first configuration signaling.

[0122] Here, if the time domain resource allocation method can be determined by downlink control information (DCI) signaling or media access control element (MAC CE) signaling, the repetition still uses a separate start symbol bit S and time domain symbol length L in the TDRA table, or uses a start and length indicator value (SLIV) field to determine the start time domain position S and time domain symbol length L of each transmission. At the same time, a repetition number field is included to determine the number N of blind retransmissions, where blind retransmissions are performed in N adjacent time slots, one complete repetition is performed in one time slot, and the symbol position for blind retransmission in each time slot is the same.

[0123] In some other embodiments, as shown in FIG. 8, S21 of the method in the embodiments of the present disclosure further includes S211D to S212D.

[0124] S211D obtains the device setting information.

[0125] In S212D, a time domain resource allocation method is determined based on the setting information of the terminal.

[0126] In an embodiment of the present disclosure, the time domain resource allocation method corresponding to the configuration information is determined by obtaining the configuration information of the terminal device, and it can be determined that the time domain resource allocation method is at least one of a transmission block over multiple slots (TBoMS) method, a repetition transmission method, and a TBoMS method with repetition transmission.

[0127] Here, the terminal determines the time domain resource allocation method by directly configuring the time domain resource allocation table or by implicit instruction.

[0128] Specifically, if only TDRA listfor repetition is set, it means that only the repetition transmission method is supported, and the transmission of transmission block over multiple slots (TBoMS) method and the TBoMS method with repetition transmission are not supported. Here, TDRA listfor repetition includes a repetition field in the TDRA table, and L is less than 1.

[0129] If only the TDRA listfor TBoMS is set, it means that the transmission of transport blocks over multiple slots (TBoMS) method is supported, where L in the TDRA table in the TDRA listfor TBoMS is greater than 14, but the repetition field is not included.

[0130] In some embodiments, the method S212D further includes SD1-SD2.

[0131] In SD1, the number of repeated transmissions is acquired.

[0132] In SD2, the corresponding time domain resource allocation method is determined based on the terminal configuration information and the number of repeated transmissions.

[0133] In an embodiment of the present disclosure, when a TDRA for TBoMS is configured in a terminal, in an embodiment of the present disclosure, a row in the TDRA table indicating a repetition number (number of repetition transmissions) > 1 in downlink control information (DCI) signaling determines whether the configuration information of the terminal device supports a TBoMS method with repetition transmissions, and if the repetition number (number of repetition transmissions) in the TDRA table is > 1, it means that the configured TDRA for TBoMS supports a TBoMS method with repetition transmissions.

[0134] In some embodiments, the method SD1 further includes steps SD11A to SD12A.

[0135] SD11A receives a set of repetition transmission counts conveyed by RMSI signaling or RRC signaling.

[0136] SD12A receives DCI signaling or MAC CE signaling, and selects a repeat transmission count from the repeat transmission count set based on the DCI signaling or MAC CE signaling.

[0137] In an embodiment of the present disclosure, a set of repeat transmission numbers carried by downlink control information (DCI) signaling or media access control element (MAC CE) signaling is received, and the second setting command is received as RMSI signaling or RRC signaling, thereby selecting a repeat transmission number from the set of repeat transmission numbers based on the RMSI signaling or RRC signaling.

[0138] In some other embodiments, the method SD1 further includes steps SD11B to SD12B.

[0139] In SD11B, the repeat transmission count setting identifier is acquired.

[0140] For SD12B, the number of repeated transmissions setting The number of repeated transmissions is determined based on the identifier.

[0141] Specifically, in the embodiment of the present disclosure, a repeat transmission count setting identifier is obtained, and the repeat transmission count setting identifier may be 0 or 1. When the repeat transmission count setting identifier is 0, it means that no repeat transmission is performed, and when the repeat transmission count setting identifier is 1, it means that repeat transmission is performed.

[0142] In the embodiment of the present disclosure, the repeat transmission count setting identifier can be set by downlink control information (DCI) signaling or media access control element (MAC CE) signaling.

[0143] In some other embodiments, the method SD1 further includes steps SD11C to SD12C.

[0144] SD11C acquires status information as to whether or not a repeated transmission field is included in the TDRA table.

[0145] In SD12C, the number of repeat transmissions is determined based on the status information.

[0146] Specifically, the status information of the repetition transmission field may be whether the TDRA table includes a repetition number field. There are multiple TDRA tables, including TDRA for repetition, TDRA for TBoMS, etc.

[0147] For example, if only TDRA for repetition is set, it means that only the repetition transmission method (Repetition) is supported and the transmission of transmission blocks over multiple slots (TBoMS) method and the TBoMS method with repetition transmission are not supported, and if only TDRA for TBoMS is set, it means that the transmission of transmission blocks over multiple slots (TBoMS) method is supported.

[0148] In some embodiments, there are multiple TDRA tables, each corresponding to one time domain resource allocation scheme.

[0149] In some embodiments, the TDRA table includes a first TDRA table and a second TDRA table, where the second TDRA table further includes a repeat transmission count relative to the first TDRA table.

[0150] The embodiments of the present disclosure may correspond to different TDRA tables for different time domain resource allocation methods. For example, if the time domain resource allocation method is a TBoMS (Transmission of Transport Blocks over Multiple Slots) method, a first TDRA table is corresponding, and if the time domain resource allocation method is a TBoMS method with repeated transmission, a second TDRA table is corresponding, and the second TDRA table includes the number of repeated transmissions.

[0151] In some embodiments, the meaning of the second field is different when the time domain resource allocation scheme is different.

[0152] Specifically, in an embodiment of the present disclosure, if the time domain resource allocation method is a transmission block over multiple slots (TBoMS) method, the second field is interpreted as the number of time slots in the TBoMS (slot number for TBoMS), and if the time domain resource allocation method is a repetition method, the second field is interpreted as the repetition number for repetition.
