detailed description

The terms "first", "second", and "third" in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to limit a specific order.

In the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

Mobile communication technology has profoundly changed people's lives, but people's pursuit of higher performance mobile communication technology has never stopped. In order to cope with the explosive growth of mobile data traffic in the future, the connection of massive mobile communication devices, and the emerging various new services and application scenarios, the fifth generation (5G) mobile communication system has emerged. The International Telecommunication Union (ITU) defines three types of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications communications, URLLC) and massive machine type communications (mMTC).

Typical eMBB services include: ultra-high-definition video, augmented reality (AR), virtual reality (VR), etc. The main characteristics of these services are large transmission data volume and high transmission rate.

Typical mMTC services include: smart grid power distribution automation, smart cities, etc. The main features are a huge number of networked devices, a small amount of transmitted data, and data insensitive to transmission delays. These mMTC terminals need to meet low cost and very long standby The need for time.

Typical URLLC businesses include: Industrial Internet of Things (IIoT) (such as wireless control in industrial manufacturing or production processes), motion control of unmanned vehicles and unmanned aircraft, remote repairs, telemedicine, etc. For haptic interactive applications, the main features of these services are ultra-high reliability, low latency, less data transmission, and suddenness. The specific requirements of the URLLC business include: data transmission reliability of 99.999%, data transmission delay of less than 1 millisecond (millisecond, ms), and meeting the requirements of high reliability and low delay to minimize instruction overhead.

In order to meet the delay requirements of the service, the time domain granularity of the resource scheduling of the 5G mobile communication system should be more flexible. Specifically, 5G supports not only the time domain scheduling granularity of the time unit level, but also the time domain scheduling granularity of the micro time unit. For example, the time unit is mainly used for eMBB services, and the micro time unit is mainly used for URLLC services. The URLLC service supports the time domain scheduling granularity of the micro time unit. It should be noted that the above-mentioned time unit and micro-time unit are general terms. A specific example can be that the time unit can be called a time slot, and the micro-time unit can be called a mini-slot or non-slot (non-slot). -based) or mini-slot; or, the time unit may be called a subframe, and the micro time unit may be called a micro subframe; other similar time domain resource division methods are not limited. The application below uses mini-slots as examples. For example, a slot may include 14 time-domain symbols, and the number of time-domain symbols included in a mini-slot is less than 14, such as 2, 3, 4, 5, 6, or 7 and so on; or, for example, a time slot may include 7 time-domain symbols, and the number of time-domain symbols included in a mini-slot is less than 7, such as 2 or 4, and the specific value is not limited. The time domain symbols here may be orthogonal frequency division multiplexing (OFDM) symbols. For a slot with a subcarrier spacing of 15 kilohertz (kilohertz, kHz), including 6 or 7 time domain symbols, the corresponding time length is 0.5ms; for a slot with a subcarrier spacing of 60kHz, the corresponding time The length is shortened to 0.125ms.

Before transmitting data between a terminal device and a network device, it is necessary to determine the time domain resources (such as OFDM symbols) occupied by the PUSCH, so that the data can be carried on the time domain resources occupied by the PUSCH for transmission. Since 5G supports the time-domain scheduling granularity of mini-slots, and in order to meet the reliability of mini-slot uplink transmission, 5G supports mini-slot PUSCH repetition/aggregation.

In order to solve the problem of how to reduce the transmission delay of the PUSCH authorized by the configuration, an embodiment of the present application provides a method for transmitting a physical uplink shared channel. The method includes: after the terminal device receives the control information, it is displayed on the uplink symbol according to the control information. The nominal PUSCH is virtually mapped, where the control information is used to indicate to send the nominal PUSCH. When the start time of the nominal PUSCH is within the configuration grant period, and the end time of the configuration grant period is between the start time of the nominal PUSCH and the end time of the nominal PUSCH, the terminal device sends the first PUSCH set, and the first PUSCH set The corresponding resources are all or part of the resources corresponding to the nominal PUSCH in the configured authorization period. The network device receives the first PUSCH set on the resource corresponding to the first PUSCH set. Therefore, by discarding the second PUSCH set mapped on the corresponding resources of the nominal PUSCH after the end of the configuration grant period, and sending the first PUSCH set mapped on the corresponding resources of the nominal PUSCH in the configuration grant period, the next configuration grant can be made Normal transmission of the nominal PUSCH in the period prevents the PUSCH exceeding the boundary of the configured authorization period from affecting the reliability and transmission delay of the PUSCH transmission in the next configured authorization period, and effectively reduces the transmission delay of the PUSCH authorized by the configuration.

It is understandable that in the embodiment of this application, the PUSCH is only used as an example of the uplink data channel. In different systems and different scenarios, the data channel may have different names, which is not the case in the embodiment of this application. Make a limit.

Fig. 2 is a first flowchart of a method for transmitting a physical uplink shared channel provided by an embodiment of the application. Here we take network equipment and terminal equipment as examples. As shown in Figure 2, the method may include:

S201: The network device sends control information to the terminal device.

S202: The terminal device receives the control information sent by the network device.

The control information is used to instruct to send the nominal PUSCH. The control information includes the starting time of the nominal PUSCH indicated by the control information, the length L of the nominal PUSCH, the number of repetitions K of the nominal PUSCH, and the configured authorization period P.

The starting time of the nominal PUSCH indicated by the control information may refer to any symbol in the configuration authorization period P.

The length of the nominal PUSCH refers to the number of symbols occupied in the time domain to transmit a nominal PUSCH. For example, the length of the nominal PUSCH can be greater than or equal to 2 symbols. For example, the length of the nominal PUSCH can be 2 symbols. The length of the nominal PUSCH can be 4 symbols. The length of the nominal PUSCH can be 7 symbols. The length of the nominal PUSCH can be 16 symbols.

The number of repetitions of the nominal PUSCH K refers to the number of repeated transmissions of data packets on the nominal PUSCH from the start time of the nominal PUSCH. Among them, K is an integer, and K≥1. For example, the value of K can be 1, 2, 4, or 8.

The configuration authorization period P refers to the period of uplink transmission without uplink authorization. The configuration authorization period can be determined according to the subcarrier interval and the number of symbols for the configuration authorization. For example, the subcarrier spacing can be 15kHz. The number of authorized symbols can be 2, 7 or n*14, where n={1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}.

It should be noted that the starting time of the nominal PUSCH and the length of the nominal PUSCH can be indicated by uplink scheduling signaling (for example, downlink control information (DCI)) or by the time domain resource allocation in the parameters of high-layer signaling Field instructions. High-level signaling may refer to signaling sent by a high-level protocol layer. The upper protocol layer is at least one protocol layer above the physical layer. Among them, the high-level protocol layer may specifically include at least one of the following protocol layers: medium access control (MAC) layer, radio link control (RLC) layer, packet data convergence protocol (packet data convergence) Protocol, PDCP) layer, radio resource control (RRC) layer and non-access stratum (NAS).

After the terminal device receives the control information, the terminal device maps the effective uplink symbols in the time domain according to the length of the nominal PUSCH and the number of repetitions of the nominal PUSCH K from the start time of the first nominal PUSCH (or called virtual mapping) PUSCH.

It should be noted that the period between the start time of the nominal PUSCH indicated by the control information and the end time of the configured grant period includes at least one valid uplink symbol and at least one non-uplink symbol.

The so-called effective uplink symbol refers to a symbol used for mapping PUSCH or uplink information. Effective uplink symbols may also include flexible symbols indicated as uplink by a slot format indicator (SFI). The uplink information includes uplink control information and uplink data information. Alternatively, the uplink information includes uplink control information. Alternatively, the uplink information includes uplink data information.

The non-uplink symbols include downlink symbols, flexible symbols indicated as downlink by SFI, and symbols within a short time interval. The downlink symbols are used for mapping PDSCH or downlink information symbols. The downlink information includes downlink control information and downlink data information. Alternatively, the downlink information includes downlink control information. Or, the downlink information includes downlink data information.

The short time interval may refer to the first time interval. The short time interval is less than or not greater than the first time interval. The length of the first time interval may refer to the length of a single symbol (Orphan symbol).

The starting time of the nominal PUSCH can be within the configured authorization period. The nominal PUSCH is mapped to at least one valid uplink symbol, and the nominal PUSCH skips at least one non-uplink symbol during mapping.

It is understandable that the time domain resources used for mapping the nominal PUSCH include at least two uplink regions. Each of the at least two uplink regions includes at least one valid uplink symbol. Any one of the at least two uplink areas is composed of M valid uplink symbols that are continuous in time. The sum of the length of the time domain of at least one uplink region corresponds to the length of the nominal PUSCH indicated by the control information, and M is a positive integer.

Any two adjacent uplink areas in the at least two uplink areas include non-uplink symbols, that is, no valid uplink symbols are included.

In this document, the nominal PUSCH is the i-th nominal PUSCH among the K nominal PUSCHs indicated by the control information, i is an integer, and 1≤i≤K.

When i=1, the starting time of the first nominal PUSCH in the K nominal PUSCHs corresponds to the starting time of the nominal PUSCH in the time domain resource allocation field. The length of the first nominal PUSCH in the K nominal PUSCHs corresponds to the length of the nominal PUSCH in the time domain resource allocation field. The first nominal PUSCH in the K nominal PUSCHs may refer to the nominal PUSCH indicated by the control information. The end time of the nominal PUSCH indicated by the control information is determined by the start time of the nominal PUSCH and the length L of the nominal PUSCH indicated by the control information. Alternatively, the end time of the nominal PUSCH indicated by the control information is the start time of the nominal PUSCH indicated by the control information, the length L of the nominal PUSCH, and the non-uplink symbol after the start time of the nominal PUSCH indicated by the control information definite.

When 2≤i≤K, the starting time of the i-th nominal PUSCH in the K nominal PUSCHs is determined by the starting time of the first nominal PUSCH, the length of the nominal PUSCH, and the starting time of the first nominal PUSCH Non-uplink symbols are determined. The length of the i-th nominal PUSCH in the K nominal PUSCHs corresponds to the length of the nominal PUSCH in the above-mentioned time domain resource allocation field. The end time of the i-th nominal PUSCH in the K nominal PUSCHs is determined by the start time of the first nominal PUSCH, the length of the nominal PUSCH, and the non-uplink symbols after the start time of the first nominal PUSCH.

The end time of the nominal PUSCH is later than the end time corresponding to the nominal PUSCH indicated by the control information.

In some embodiments, if no non-uplink symbols are included between the start time of the nominal PUSCH indicated by the control information and the end time of the configured grant period, the start time S of the nominal PUSCH can be expressed as S0+(i-1)*L . The end time of the nominal PUSCH can be expressed as S0+i*L. Among them, S0 represents the start time of the first nominal PUSCH among the K nominal PUSCHs indicated by the control information.

In other embodiments, if the time between the start time of the nominal PUSCH indicated by the control information and the end time of the configured grant period includes at least one valid uplink symbol and at least one non-uplink symbol, the start time S of the nominal PUSCH can be expressed as S0+(i-1)*L+N _{_NUL} . The end time of the nominal PUSCH can be expressed as S0+i*L+N _{_NUL_2} . N _{_NUL} represents the number of non-uplink symbols between the start time of the first nominal PUSCH in the K nominal PUSCHs and the start time of the nominal PUSCH, N _{_NUL_2} represents the start of the first nominal PUSCH in the K nominal PUSCHs The number of non-uplink symbols between time and the end time of the nominal PUSCH.

In particular, the start time S of the first nominal PUSCH in the K nominal PUSCHs can be expressed as S0+N _{_NUL} , and S0+N _{_NUL} can represent the start time of the first nominal PUSCH in the K nominal PUSCHs and There are non-uplink symbols between the starting moments indicated by the control information.

For example, the end time of the configured authorization period is between the start time of the nominal PUSCH and the end time of the nominal PUSCH.

The specific situation of the PUSCH mapped in the time domain will be described below with an example.

In the first possible implementation manner, assuming K=1, it means that the nominal PUSCH is sent once from the start time of the nominal PUSCH indicated by the control information. The length L of the nominal PUSCH is 8 symbols, the start time of the nominal PUSCH is before the end time of the configured authorization period, and the end time of the nominal PUSCH is after the end time of the configured authorization period.

In some embodiments, as shown in FIG. 3, the starting time of the nominal PUSCH indicated by the control information is the first symbol in time slot n+1, because the first symbol to the fourth symbol in time slot n+1 The symbol is a downlink symbol, and the PUSCH cannot be mapped on the first symbol to the fourth symbol, and the mapping of the nominal PUSCH is delayed. The first uplink symbol (the 5th symbol of slot n+1) after the downlink symbol starts to map the nominal PUSCH. The start time of the first nominal PUSCH is the 5th symbol of time slot n+1, the terminal device maps 8 symbols, and the end time of the first nominal PUSCH is the 12th symbol of time slot n+1. Since the length of the first nominal PUSCH is greater than the length between the start time of the first nominal PUSCH and the end time of the configured grant period, the PUSCH mapped on the 11th and 12th symbols of time slot n+1 is After the end boundary of the configured authorization period, therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

It is understandable that the nominal PUSCH is divided into two segments at the end of the configuration grant period. The PUSCH mapped on the 5th symbol to the 10th symbol of time slot n+1 can be called the first PUSCH, which is mapped on the time slot. The PUSCH on the 11th symbol and the 12th symbol of n+1 may be referred to as the second PUSCH. The first PUSCH and the second PUSCH are located in the same uplink region.

In other embodiments, as shown in FIG. 4, the starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the nominal PUSCH is the 11th symbol in time slot n. The terminal device maps 4 symbols to the 14th symbol of time slot n. Since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided by the time slot boundary, and since time slot n+ The first symbol to the fourth symbol of 1 are downlink symbols, and the PUSCH cannot be mapped from the first symbol to the fourth symbol, and the mapping of the first nominal PUSCH is delayed. The first uplink symbol after the downlink symbol (the fifth symbol of time slot n+1) starts to map the first nominal PUSCH, that is, continues to map 4 symbols, and the end time of the first nominal PUSCH is time slot n+ The eighth symbol of 1. Since the length from the 5th symbol of time slot n+1 to the end time of the first nominal PUSCH is greater than the length from the 5th symbol of time slot n+1 to the end time of the configured authorization period, it is mapped in the time slot The PUSCH on the 7th symbol and the 8th symbol of n+1 is after the end boundary of the configured authorization period. Therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

It is understandable that the nominal PUSCH is divided into three segments by configuring the end time of the grant period and non-uplink symbols. The PUSCH mapped on the 11th symbol to the 14th symbol of time slot n can be called the first PUSCH, which is mapped on The PUSCH on the 5th and 6th symbols of time slot n+1 can be called the second PUSCH, and the PUSCH mapped on the 7th and 8th symbols of time slot n+1 can be called the third PUSCH. The second PUSCH and the third PUSCH are located in the same uplink region.

In other embodiments, as shown in FIG. 5, the starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the nominal PUSCH is the 11th symbol in time slot n. Mapping 4 symbols to the 14th symbol of time slot n, since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided into the slot boundary, and 2 symbols are further mapped to the time slot The second symbol of n+1, since the third symbol to the sixth symbol of slot n+1 are downlink symbols, the PUSCH cannot be mapped on the third symbol to the sixth symbol, so the mapping of the first symbol is delayed Nominal PUSCH. The first uplink symbol after the downlink symbol (the seventh symbol of time slot n+1) starts to map the first nominal PUSCH, that is, continues to map 2 symbols, and the end time of the first nominal PUSCH is time slot n+ The eighth symbol of 1. Since the 3rd to 6th symbols of time slot n+1 are downlink symbols, the first nominal PUSCH mapping is postponed, and the PUSCH on the 7th symbol and 8th symbol of time slot n+1 is allocated for authorization After the end of the period boundary, therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

It is understandable that the nominal PUSCH is divided into three segments by configuring the end time of the grant period and non-uplink symbols. The PUSCH mapped on the 11th symbol to the 14th symbol of time slot n can be called the first PUSCH, which is mapped on The PUSCH on the first symbol to the second symbol of time slot n+1 can be called the second PUSCH, and the PUSCH mapped on the 7th and 8th symbols of time slot n+1 can be called the third PUSCH.

It should be noted that the time interval between the start time of the nominal PUSCH and the end time of the configured authorization period needs to be greater than or not less than the first time interval, which is predefined or notified by the network device. For example, the first time interval is one symbol.

In other embodiments, as shown in FIG. 6, the starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the nominal PUSCH is the 11th symbol in time slot n. 4 symbols are mapped to the 14th symbol of time slot n. Since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided by the slot boundary. The time interval between the start of 1 symbol and the end of the configured authorization period is less than the first time interval. Therefore, PUSCH is not mapped on the first symbol of time slot n+1, and since the first symbol of time slot n+1 The second symbol to the fifth symbol are downlink symbols, and the PUSCH cannot be mapped on the second symbol to the fifth symbol, and the mapping of the first nominal PUSCH is delayed. The first uplink symbol after the downlink symbol (the 6th symbol of time slot n+1) starts to map the first nominal PUSCH, but it should be from the start time of the first uplink symbol after the downlink symbol to the configuration grant The time interval between the end moments of the period is less than the first time interval. Therefore, PUSCH is not mapped on the 6th symbol of time slot n+1, and the first uplink symbol after the end time of the configured grant period (time slot n (7th symbol of +1) and then continue to map the nominal PUSCH, that is, map the PUSCH on the 7th symbol to the 10th symbol of slot n+1, that is, continue to map 3 symbols, and the end time of the nominal PUSCH is the slot The tenth symbol of n+1. Since the second symbol to the fifth symbol of time slot n+1 are downlink symbols, the first nominal PUSCH mapping is postponed, and the PUSCH on the seventh symbol to the tenth symbol of time slot n+1 is configured for authorization After the end boundary of the period, therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

Understandably, configuring the end time of the grant period and the non-uplink symbol splits the nominal PUSCH into two segments, which are mapped on the 11th symbol to the 14th symbol of time slot n and the first symbol of time slot n+1 The PUSCH may be referred to as the first PUSCH, and the PUSCH mapped on the seventh symbol to the tenth symbol of the time slot n+1 may be referred to as the second PUSCH.

In the second achievable manner, assuming K=2, it means that the nominal PUSCH is sent twice from the start time of the nominal PUSCH indicated by the control information. The length L of the nominal PUSCH is 4 symbols. The start time of the nominal PUSCH is before the end time of the configuration authorization period, and the end time of the nominal PUSCH is after the end time of the configuration authorization period.

In some embodiments, as shown in FIG. 7, the starting time of the nominal PUSCH indicated by the control information is the first symbol in time slot n+1, since the first symbol to the fourth symbol in time slot n+1 The symbol is a downlink symbol, and the PUSCH cannot be mapped on the first symbol to the fourth symbol, and the mapping of the nominal PUSCH is delayed. The first uplink symbol (the 5th symbol of slot n+1) after the downlink symbol starts to map the nominal PUSCH. The start time of the first nominal PUSCH is the 5th symbol of time slot n+1, and 4 symbols are mapped, and the end time of the first nominal PUSCH is the 8th symbol of time slot n+1. The ninth symbol of time slot n+1 is an uplink symbol, and the second nominal PUSCH continues to be mapped. The start time of the second nominal PUSCH is the ninth symbol of time slot n+1, and 4 symbols are mapped. The end time of each nominal PUSCH is the 12th symbol of time slot n+1. Since the length of the second nominal PUSCH is greater than the length between the start time of the second nominal PUSCH and the end time of the configured grant period, the PUSCH mapped on the 11th and 12th symbols of time slot n+1 is After the end boundary of the configured authorization period, therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

Understandably, a complete nominal PUSCH is mapped in the configuration authorization period, that is, the first nominal PUSCH. The first nominal PUSCH may be referred to as the first PUSCH. The second nominal PUSCH is divided into two segments at the end of the configuration grant period. The PUSCH mapped on the 9th symbol to the 10th symbol of time slot n+1 can be called the second PUSCH and is mapped on time slot n The PUSCH on the 11th symbol and the 12th symbol of +1 may be referred to as the third PUSCH. The second PUSCH and the third PUSCH are located in the same uplink region.

In other embodiments, as shown in FIG. 8, the starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the first nominal PUSCH is the 11th symbol in time slot n. 4 symbols are mapped, and the end time of the first nominal PUSCH is the 14th symbol of time slot n+1. Since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided at the time slot boundary, and since the first to fourth symbols of time slot n+1 are downlink symbols, it cannot When the PUSCH is mapped on the first symbol to the fourth symbol, the mapping of the second nominal PUSCH is delayed. After the downlink symbol, the first uplink symbol (the fifth symbol of time slot n+1) starts to map the second nominal PUSCH. The start time of the second nominal PUSCH is the 5th symbol of time slot n+1, and 2 symbols are mapped, and the end time of the second nominal PUSCH is the 8th symbol of time slot n+1. Since the length of the second nominal PUSCH is greater than the length between the start time of the second nominal PUSCH and the end time of the configured grant period, the PUSCH mapped on the 7th and 8th symbols of time slot n+1 is After the end boundary of the configured authorization period, therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

Understandably, a complete nominal PUSCH is mapped in the configuration authorization period, that is, the first nominal PUSCH. The first nominal PUSCH may be referred to as the first PUSCH. The second nominal PUSCH is divided into two segments at the end of the configuration grant period. The PUSCH mapped on the 5th symbol to the 6th symbol of time slot n+1 can be called the second PUSCH and is mapped on time slot n The PUSCH on the 7th symbol and the 8th symbol of +1 may be referred to as the third PUSCH.

In other embodiments, as shown in FIG. 9, the starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the first nominal PUSCH is the 11th symbol in time slot n. 4 symbols are mapped, and the end time of the first nominal PUSCH is the 14th symbol of time slot n+1. Since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided by the time slot boundary. The first symbol of time slot n+1 is an uplink symbol, and the second nominal PUSCH continues to be mapped. The start time of the second nominal PUSCH is the first symbol of time slot n+1, and 2 symbols are mapped. Since the third symbol to the fifth symbol of time slot n+1 are downlink symbols, it cannot be used in the third symbol. If the PUSCH is mapped from the first symbol to the fifth symbol, the mapping of the second nominal PUSCH is delayed. After the downlink symbol, the first uplink symbol (the 6th symbol of time slot n+1) starts to map the second nominal PUSCH. However, the time interval between the start time of the 6th symbol of time slot n+1 and the end time of the configured authorization period is less than the first time interval, therefore, PUSCH is not mapped on the 6th symbol of time slot n+1 , The PUSCH is mapped after the end time of the configured authorization period, that is, the second nominal PUSCH is continuously mapped on the seventh symbol to the eighth symbol of time slot n+1, and the end time of the second nominal PUSCH is the time slot The eighth symbol of n+1. Since the PUSCH mapped on the 7th symbol and the 8th symbol of the time slot n+1 is after the end boundary of the configured grant period, the end time of the nominal PUSCH is after the end time of the configured grant period.

Understandably, a complete nominal PUSCH is mapped in the configuration authorization period, that is, the first nominal PUSCH. The first nominal PUSCH may be referred to as the first PUSCH. The second nominal PUSCH is divided into two segments at the end of the configuration grant period. The PUSCH mapped on the first symbol to the second symbol of time slot n+1 can be called the second PUSCH, which is mapped on time slot n The PUSCH on the 7th symbol and the 8th symbol of +1 may be referred to as the third PUSCH. The third PUSCH and the fourth PUSCH are located in the same uplink region.

In some embodiments, as shown in FIG. 10, assuming K=3, it means that the nominal PUSCH is sent three times from the start time of the nominal PUSCH indicated by the control information. The starting time of the nominal PUSCH indicated by the control information is the first symbol in time slot n+1. Since the first symbol to the fourth symbol in time slot n+1 are downlink symbols, it cannot be used between the first symbol and the fourth symbol. If PUSCH is mapped on the 4th symbol, mapping of nominal PUSCH is delayed. The first uplink symbol (the 5th symbol of slot n+1) after the downlink symbol starts to map the nominal PUSCH. The start time of the first nominal PUSCH is the 5th symbol of time slot n+1, and 4 symbols are mapped, and the end time of the first nominal PUSCH is the 8th symbol of time slot n+1. The ninth symbol of time slot n+1 is an uplink symbol, and the second nominal PUSCH continues to be mapped. The start time of the second nominal PUSCH is the ninth symbol of time slot n+1, and 4 symbols are mapped. The end time of each nominal PUSCH is the 12th symbol of time slot n+1. Since the length of the second nominal PUSCH is greater than the length between the start time of the second nominal PUSCH and the end time of the configured grant period, the PUSCH mapped on the 11th and 12th symbols of time slot n+1 is After the end boundary of the configured authorization period. In addition, the start time of the third nominal PUSCH is the 13th symbol of time slot n+1, and 2 symbols are mapped. Since the first symbol to the second symbol of time slot n+2 are downlink symbols, it cannot be When PUSCH is mapped on the first symbol to the second symbol, the mapping of the nominal PUSCH is delayed. The first uplink symbol after the downlink symbol (the third symbol of time slot n+2) starts to map the nominal PUSCH, and 2 symbols are mapped. The end time of the third nominal PUSCH is the fourth time of time slot n+2 symbol. Therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

Understandably, a complete nominal PUSCH is mapped in the configuration authorization period, that is, the first nominal PUSCH. The first nominal PUSCH may be referred to as the first PUSCH. The second nominal PUSCH is divided into two segments at the end of the configuration grant period. The PUSCH mapped on the 9th symbol to the 10th symbol of time slot n+1 can be called the second PUSCH and is mapped on time slot n The PUSCH on the 11th symbol and the 12th symbol of +1 may be referred to as the third PUSCH. The PUSCH mapped on the 13th symbol and the 14th symbol of the time slot n+1 may be referred to as the fourth PUSCH. The PUSCH mapped on the 3rd symbol and the 4th symbol of time slot n+2 can be called the fifth PUSCH. The second PUSCH, the third PUSCH and the fourth PUSCH are located in the same uplink region.

In other embodiments, as shown in FIG. 11, the thirteenth symbol in slot n and the third symbol in slot n+1 are flexible symbols or the symbols are dynamic flexible symbols. Since the 13th symbol in the time slot n is indicated by the SFI as an uplink flexible symbol or the symbol is a dynamic flexible symbol, the 13th symbol in the time slot n can be used to transmit the PUSCH. Since the third symbol in the time slot n+1 is indicated as a flexible downlink symbol by the SFI, the third symbol in the time slot n+1 cannot be used to transmit PUSCH.

The starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the first nominal PUSCH is the 11th symbol in time slot n. 4 symbols are mapped, and the first nominal PUSCH is The end time of is the 14th symbol of time slot n+1. Since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided at the time slot boundary, and since the first to fourth symbols of time slot n+1 are downlink symbols, it cannot When the PUSCH is mapped on the first symbol to the fourth symbol, the mapping of the second nominal PUSCH is delayed. After the downlink symbol, the first uplink symbol (the fifth symbol of time slot n+1) starts to map the second nominal PUSCH. The start time of the second nominal PUSCH is the 5th symbol of time slot n+1, and 2 symbols are mapped, and the end time of the second nominal PUSCH is the 8th symbol of time slot n+1. Since the length of the second nominal PUSCH is greater than the length between the start time of the second nominal PUSCH and the end time of the configured grant period, the PUSCH mapped on the 7th and 8th symbols of time slot n+1 is After the end boundary of the configured authorization period, therefore, the end time of the nominal PUSCH is after the end time of the configured authorization period.

In the third achievable manner, assuming K=4, it means that the nominal PUSCH is sent twice from the start time of the nominal PUSCH indicated by the control information. The length L of the nominal PUSCH is 2 symbols. The start time of the nominal PUSCH is before the end time of the configuration authorization period, and the end time of the nominal PUSCH is after the end time of the configuration authorization period.

In some embodiments, as shown in FIG. 12, the starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n, and the starting time of the first nominal PUSCH is the 11th symbol in time slot n. Symbol, 2 symbols are mapped, and the end time of the first nominal PUSCH is the 12th symbol of time slot n+1. The 13th symbol of time slot n is an uplink symbol, and the second nominal PUSCH continues to be mapped. The start time of the second nominal PUSCH is the 13th symbol of time slot n, and 2 symbols are mapped, and the end time of the second nominal PUSCH is the 14th symbol of time slot n+1. Since the next uplink symbol is the first symbol of time slot n+1, the nominal PUSCH is divided by the time slot boundary. In addition, since the first symbol to the fourth symbol of the time slot n+1 are downlink symbols, and the PUSCH cannot be mapped on the first symbol to the fourth symbol, the mapping of the nominal PUSCH is delayed. The first uplink symbol (the 5th symbol of slot n+1) after the downlink symbol starts to map the nominal PUSCH. The start time of the third nominal PUSCH is the fifth symbol of time slot n+1, and 2 symbols are mapped, and the end time of the third nominal PUSCH is the sixth symbol of time slot n+1. The seventh symbol of time slot n+1 is the uplink symbol, and the fourth nominal PUSCH continues to be mapped. The start time of the fourth nominal PUSCH is the seventh symbol of time slot n+1, and 2 symbols are mapped. The end time of each nominal PUSCH is the 8th symbol of time slot n+1. Since the PUSCH mapped on the 7th symbol and the 8th symbol of the time slot n+1 is after the end boundary of the configured grant period, the end time of the nominal PUSCH is after the end time of the configured grant period.

Understandably, three complete nominal PUSCHs are mapped in the configuration authorization period, that is, the first nominal PUSCH, the second nominal PUSCH, and the third nominal PUSCH. The first nominal PUSCH may be referred to as the first PUSCH. The second nominal PUSCH may be referred to as the second PUSCH. The third nominal PUSCH may be referred to as the third PUSCH. The PUSCH mapped on the 7th symbol and the 8th symbol of the time slot n+1 may be referred to as the fourth PUSCH.

In the fourth achievable manner, the transmission start time of the nominal PUSCH is equal to the end time of the configuration authorization period, and the transmission end time of the nominal PUSCH is after the end time of the configuration authorization period.

In some embodiments, as shown in FIG. 13, assuming K=2, it means that the nominal PUSCH is sent twice from the start time of the nominal PUSCH indicated by the control information. The length L of the nominal PUSCH is 4 symbols. The starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n. However, starting from the 11th symbol in slot n, the symbols in the entire configuration grant period are downlink symbols, and the first uplink symbol after the end of the configuration grant period (the seventh symbol in slot n+1) Symbol) start mapping, the start time of the first nominal PUSCH is the 7th symbol in slot n+1, and 4 symbols are mapped, and the end time of the first nominal PUSCH is the 10th symbol in slot n+1 Symbol, the start time of the second nominal PUSCH is the 11th symbol in time slot n+1, and 4 symbols are mapped, and the end time of the second nominal PUSCH is the 14th symbol in time slot n+1. Since both the first nominal PUSCH and the second nominal PUSCH exceed the end boundary of the configuration authorization period, the end time of the nominal PUSCH is after the end time of the configuration authorization period.

Understandably, the first nominal PUSCH may be referred to as the first PUSCH. The second nominal PUSCH may be referred to as the second PUSCH.

In some embodiments, as shown in FIG. 14, assuming K=2, it means that the nominal PUSCH is sent twice from the start time of the nominal PUSCH indicated by the control information. The length L of the nominal PUSCH is 4 symbols. The starting time of the nominal PUSCH indicated by the control information is the 11th symbol in time slot n. However, from the 11th symbol in time slot n to the 14th symbol in time slot n, the first symbol in time slot n+1 to the fifth symbol in time slot n+1 are all downlink symbols , PUSCH cannot be mapped. The first uplink symbol (the 6th symbol of time slot n+1) after the downlink symbol starts to map the first nominal PUSCH, but it should be mapped from the first uplink symbol after the downlink symbol. The time interval between the start time and the end time of the configured authorization period is less than the first time interval. Therefore, PUSCH is not mapped on the 6th symbol of time slot n+1, and the first uplink after the end time of the configured authorization period The symbol (the 7th symbol of time slot n+1) continues to be mapped to the nominal PUSCH. The starting time of the first nominal PUSCH is the 7th symbol in time slot n+1. 4 symbols are mapped, and the first nominal PUSCH is mapped The end time of PUSCH is the 10th symbol of time slot n+1, and the start time of the second nominal PUSCH is the 11th symbol in time slot n+1. 4 symbols are mapped, and the end of the second nominal PUSCH The time is the 14th symbol of time slot n+1. Since both the first nominal PUSCH and the second nominal PUSCH exceed the end boundary of the configuration authorization period, the end time of the nominal PUSCH is after the end time of the configuration authorization period.

In other embodiments, if the first symbol after the end time of the configured grant period is a non-uplink symbol, the first uplink symbol after the non-uplink symbol is mapped to the nominal PUSCH.

It should be noted that the foregoing various mapping methods for the nominal PUSCH are just examples. Due to different combinations of uplink symbols, non-uplink symbols, and downlink symbols, the nominal PUSCH mapping may also have other methods, which will not be repeated in this application.

S203: The terminal device sends the first PUSCH set.

The resources corresponding to the first PUSCH set are all or part of the resources corresponding to the nominal PUSCH in the configured authorization period.
