Background technique

When sending a transmission block (bransmission block, TB), it is generally transmitted through a time slot (slot). Before sending a transport block, it is necessary to calculate the resources occupied by the transport block. Currently, the number of symbols occupied by a transmission is specified. This number is less than or equal to 14, and 14 is the maximum OFDM that can be provided by a time slot. (orthogonal frequency division multiplexing, OFDM) number of symbols.

In order to use a lower code rate when transmitting data, a mode of carrying one transmission block over multiple slots (TBoMS) is now proposed, that is, one transmission block is carried on multiple slots. Since the TBoMS contains multiple time slots, the existing calculation method cannot be used when calculating the resources occupied by the TBoMS. At present, no solution has been provided for how to calculate the resources occupied by TBoMS. Since the resources occupied by TBoMS cannot be calculated, the TBoMS transmission scheme may not be realized.

S301. The network device sends first configuration information to the UE. Correspondingly, the UE receives first configuration information from the network device.

The first configuration information may configure the number of time domain resource units included in the first time domain resource. The first time domain resource is, for example, the time domain resource used by the UE to send a transport block to be transmitted (for example, called the first transport block) to the network device, but the first time domain resource may not be actually used by the UE to send the first transport block The time domain resource, that is, the first time domain resource is only configured by the network device, but the UE may further determine the time domain resource actually used for sending the first transport block. The first time domain resource includes multiple time domain resource units. Types of time domain resource units included in the first time domain resource include, for example, one or more of uplink time domain resource units, special time domain resource units, or downlink time domain resource units. Wherein, the first transport block can occupy the uplink time domain resource unit and some sub-time domain resource units in the special time domain resource unit. For the downlink time domain resource unit and the remaining sub-time domain resources in the special time domain resource unit Units are non-occupiable. That is to say, the time-domain resource units included in the first time-domain resource indicated by the first configuration information may be occupied by the first transport block, or the first transport block may only occupy part of the time-domain resource units. .

The time-domain resource unit is, for example, a subframe (subframe), a time slot, a mini-slot (mini-slot), or an OFDM symbol (also referred to as a symbol (symbol) for short). Taking the resource unit in the time domain as a time slot as an example, this transmission mode can be regarded as a TBoMS mode. In addition, the embodiments of the present application will also refer to concepts such as special time-domain resource units, uplink time-domain resource units, downlink time-domain resource units, and sub-time-domain resource units. The time domain resource unit, the uplink time domain resource unit, the downlink time domain resource unit and the special time domain resource unit are the same type of time unit. For example, the time domain resource unit is a time slot, and the special time domain resource unit is a special time slot. The time domain resource unit is an uplink time slot, and the downlink time domain resource unit is a downlink time slot. The sub-time-domain resource units are obtained by further dividing the time-domain resource units. For example, it can be understood that a time-domain resource unit may include one or more sub-time-domain resource units. For example, if the time-domain resource unit is a subframe, the sub-time-domain resource unit is, for example, a time slot, mini-slot, or symbol; for another example, if the time-domain resource unit is a time slot, the sub-time-domain resource unit is, for example, a symbol. For ease of understanding, in the introduction process of the embodiments of this application and the following embodiments, the time domain resource unit is a time slot, the special time domain resource unit is a special time slot, and the uplink time domain resource unit is an uplink time slot. 1. The downlink time domain resource unit is a downlink time slot, the sub-time domain resource unit is a symbol, and the transmission mode is TBoMS as an example. That is to say, the time slots described in the embodiments of this application and the following embodiments can be replaced by time domain resource units, special time slots can be replaced by special time domain resource units, and uplink time slots can be replaced by uplink time domain resource units. Both the time-domain resource unit and the downlink time slot can be replaced with downlink time-domain resource units, and the symbols can be replaced with sub-time-domain resource units.

Optionally, the first configuration information may also configure the initial time domain position of the first time domain resource. Alternatively, the first configuration information does not need to configure the initial time domain position of the first time domain resource. For example, the network device will also send scheduling signaling to the UE, where the scheduling signaling is, for example, downlink control information (DCI), or other signaling. The scheduling signaling may schedule the first transport block. The UE can determine that the first transmission block needs to be sent when the first duration from the time slot receiving the scheduling signaling arrives. The first duration is the time interval between the UE receiving the scheduling signaling and sending the transmission block, which is known to the UE . That is to say, the UE can determine the initial time domain position of the first time domain resource according to the time when the scheduling signaling is received, without first configuration information configuration.

For example, the network device sends radio resource control (radio resource control, RRC) signaling to the UE, where the RRC signaling may indicate multiple configuration information, and the first configuration information is one of them. Each piece of configuration information in the plurality of configuration information may indicate the number of time slots included in the time domain resource, and optionally, may also indicate the initial time domain position of the time domain resource. For example, the starting time domain position of the time domain resource may be the number of a symbol in a time slot, where the time slot is the starting time slot of the time domain resource, and the symbol is the starting symbol of the time domain resource. The time domain resources indicated by different configuration information include the same or different numbers of time slots, and/or the time domain resources indicated by different configuration information have the same or different starting time domain positions. For example, in RRC signaling, a plurality of configuration information is included in time domain resource allocation (time domain resource allocation, TDRA), and TDRA is presented in the form of a table or multiple entries. If presented in a table form, each row of the table is It can be understood as a piece of configuration information. If it is presented in the form of multiple entries, each entry can be understood as a piece of configuration information. Alternatively, multiple pieces of configuration information may also be presented in other forms in the RRC signaling.

If this is the case above, the network device may also send first signaling to the UE. The first signaling is, for example, dynamic signaling, such as DCI. The first signaling may indicate the first configuration information. The first signaling and the scheduling signaling may be the same signaling, or may be different signaling. That is to say, the RRC signaling may include a plurality of configuration information, and the first configuration information is indicated through the first signaling, so that the UE can clearly determine that the first configuration information needs to be applied. The first configuration information in S301 may be considered to be included in the RRC signaling, or may be considered to be included in the first signaling.

Alternatively, the RRC signaling only includes the first configuration information and does not include other configuration information. If this is the case, the network device may not have to send the first signaling to the UE. At this point, the first configuration information in S301 may be considered to be included in the RRC signaling.

Optionally, the above RRC signaling may also be replaced with other types of signaling, such as media access control (media access control, MAC) control element (control element, CE) and so on.

TBoMS may occupy a special time slot, which can include uplink symbols, downlink symbols and flexible symbols, and symbols that can be used to send uplink information include uplink symbols and some flexible symbols (for example, this part of flexible symbols is a special time slot Among all the flexible symbols included in the time slot, the remaining flexible symbols except the flexible symbols used for uplink and downlink conversion), that is to say, not all the symbols in the special time slot can be used to send uplink information. Therefore, if TBoMS occupies a special time slot, to determine the time domain resource occupied by TBoMS, or to determine the time domain resource occupied by the first transmission block, it is necessary to know how many symbols the first transmission block occupies in the special time slot . Then, if the first time domain resource indicated by the first configuration information includes a special time slot, then optionally, the first configuration information may further configure the number of symbols occupied by the first time domain resource in the special time slot. It can be understood that the first configuration information can also configure the number of symbols used to carry the TBoMS in the special time slot, or in other words, the first configuration information can also configure the number of symbols used to carry the first transport block in the special time slot. number. For example, the number of symbols used to bear the TBoMS in the special time slot configured by the first configuration information is the first number. Wherein, if the TBoMS occupies multiple special time slots, the first quantity configured in the first configuration information may be the number of symbols occupied in the first special time slot included in the first ToT in the time domain in the TBoMS number, or, the first number configured in the first configuration information may also be the number of symbols occupied in any special time slot in the TBoMS.

Alternatively, the first configuration information may not configure the first number, and the first number may be determined by the UE itself. For example, the first number is the number of symbols occupied in the special time slot included in the first ToT in the time domain in the TBoMS, and the initial time domain position of the first time domain resource is located in the first time slot, for example. A time slot may be a special time slot included in a ToT in the internal time domain of TBoMS, and the UE can determine the first number according to the initial time domain position of the first time domain resource. Or, if the first configuration information does not configure the first number, if the first time slot is not a special time slot but an uplink time slot, and the initial time domain position of the first time domain resource is located at the The first symbol, and the previous time slot of the first time slot is a special time slot, then the UE can still determine the number of symbols occupied by the TBoMS in the special time slot (understood at this time, if according to the first configuration information, Then TBoMS does not occupy any symbols in this special time slot, but UE can move forward the initial time domain position of the first time domain resource by itself, so that TBoMS occupies one or more symbols in this special time slot, or That is, the initial time domain position of the TBoMS is changed to be located in the special time slot, so as to make full use of resources), and this number is also the first number. For example, the first quantity at this time includes all uplink symbols in the special time slot, and the remaining flexible symbols in the special time slot except the flexible symbols used for uplink and downlink conversion. In this way, when the UE determines the time domain resources occupied by TBoMS, it also includes the special time slots not indicated by the network equipment into the calculation process. It will be used. If TBoMS is not used for transmission, it is not necessary to use this method to determine the time domain resources occupied by transmission. Therefore, this calculation method does not affect the existing non-TBoMS method of determining time domain resources.

S302. The UE determines a second time domain resource according to the first value and the number of uplink time domain resource units included in the first time domain resource. In other words, the UE determines the second time domain resource according to the first value and the number of uplink time domain resource units occupied by the TBoMS (or, first transport block). The second time-domain resource is a time-domain resource occupied by a transport block (for example, called a first transport block) to be sent by the UE. In other words, the UE determines the time domain resources (that is, the second time domain resources) occupied by the TBoMS according to the first value and the number of uplink time domain resource units occupied by the TBoMS. The first time domain resource here refers to the time domain resource indicated by the first configuration information, or if the UE moves forward the initial time domain position according to the method described in the preceding steps, the first time domain resource here refers to The time domain resources occupied by the TBoMS after the UE moves its initial time domain position. Here, the first time-domain resource may be generally understood as the time-domain resource configured by the network device for sending the first transport block. The second time-domain resource is the time-domain resource used by the UE to send the first transport block. The first time-domain resource and the second time-domain resource may be the same time-domain resource, or may be different or not completely the same time-domain resource. resource.

For example, the first value is expressed by L, for example, L is understood as the number of sub-time domain resource units allocated to a physical uplink shared channel (PUSCH). The first value may be configured through first configuration information, or the first value may also be predefined through a protocol, or preconfigured in the network device and the UE. Wherein, the number of time-domain resource units included in the first time-domain resource configured by the first configuration information can also be understood as the number of repetitions of the first value configured by the first configuration information.

Optionally, the UE determines the second time domain resource according to the first value and the number of uplink time domain resource units occupied by the TBoMS. One way is: the UE determines the second time domain resource according to L, the number of uplink time slots included in the first time domain resource (or more precisely, the number of uplink time slots occupied by TBoMS), the number of special time slots included in the first time domain resource (or more precisely, the number of special time slots occupied by TBoMS) , and the first quantity, determine a second time domain resource. Optionally, the first value is 14, or other values, such as positive integers smaller than 14. For example, the UE determines the range of time slots occupied by the TBoMS according to the number of time slots included in the first time domain resource indicated by the first configuration information, and/or according to the initial time domain position of the first time domain resource, or the The range of time domain resources, so that the number of uplink time slots occupied by the TBoMS and the number of special time slots occupied by the TBoMS can be determined. Or, the UE determines the time slot occupied by the first ToT of the TBoMS according to the number of time slots included in the first time domain resource indicated by the first configuration information, and/or according to the initial time domain position of the first time domain resource range, or the range of the first ToT of the time domain resource, so that the number of uplink time slots occupied by the ToT and the number of special time slots occupied by the ToT can be determined. At this time, it is used to determine the second time slot The number of uplink time slots occupied by the TBoMS of the domain resource may refer to the number of uplink time slots occupied by the ToT, and the number of special time slots used to determine the TBoMS of the second time domain resource may refer to the number of uplink time slots occupied by the ToT. The number of special time slots.

For example, according to the initial time domain position of the first time domain resource, the number of time slots indicated by the first configuration information (or the number of repetitions of L indicated by the first configuration information), and the time division multiplexing (time division duplexing) , TDD) ratio, the range of the first time domain resource can be determined, or in other words, the initial time domain position and the end time domain position of the first time domain resource can be determined, and the unit of the determined end time domain position at this time can be Symbols can also be slots. According to the TDD allocation ratio and the range of the first time domain resource, the UE can determine the uplink time slots and special time slots actually included in the range. The TDD configuration can indicate the allocation proportions of uplink time slots, downlink time slots, and special time slots.

In a possible implementation, the number of uplink time slots involved in determining the second time domain resource in this embodiment of the application, that is, the number of uplink time slots occupied by TBoMS does not necessarily refer to the actual uplink time slots , but refers to the uplink time slot in which the number of symbols occupied by the TBoMS is greater than or equal to L. For example, the UE determines that the range actually includes 3 uplink time slots, the starting time domain position of TBoMS is located in the first uplink time slot of the 3 uplink time slots, and TBoMS only occupies the first uplink time slot. For example, the number of symbols occupied by TBoMS in the first uplink time slot is less than L, while in the other two uplink time slots, the number of symbols occupied by TBoMS is greater than or equal to L. In this case, the UE may determine that the number of uplink time slots participating in the determination of resources in the second time domain is 2 instead of 3, that is, the first uplink time slot is not considered as participating in the determination of resources in the second time domain. The uplink time slot of the resource. In addition, in the embodiment of the present application, the number of special time slots involved in determining the second time domain resource, that is, the number of special time slots occupied by TBoMS, does not necessarily refer to the actual special time slots, but refers to the number of special time slots in which TBoMS The number of symbols occupied is less than L uplink time slots. For example, the UE determines that the range actually includes 3 uplink time slots and 1 special time slot, the starting time domain position of TBoMS is located in the first uplink time slot of these 3 uplink time slots, and TBoMS only occupies For example, the number of symbols occupied by TBoMS in the first uplink time slot is less than L, while in the other two uplink time slots, the number of symbols occupied by TBoMS is greater than or equal to L. In addition, the number of symbols occupied by TBoMS in this special time slot is less than L. In this case, the UE may determine that the number of special time slots involved in determining resources in the second time domain is 2 instead of 1, that is, the first uplink time slot is not considered as participating in determining the resources in the second time domain. The uplink time slot of the resource is regarded as a special time slot participating in determining the second time domain resource. That is to say, in this embodiment of the application, the number of uplink time slots and the number of special time slots applicable to the UE when determining the second time domain resource occupied by the first transport block are based on the TBoMS in the corresponding time slot The number of symbols occupied is determined, and does not necessarily refer to the real uplink time slot or special time slot.

Optionally, according to L, the number of uplink time slots included in the first time domain resource (or more precisely, the number of uplink time slots occupied by TBoMS), and the number of special time slots included in the first time domain resource The number of (or more precisely, the number of special time slots occupied by TBoMS), and the first number, determine the second time domain resource, for example, one way is, UE according to L, the uplink time slot occupied by TBoMS The number of L, the number of special time slots occupied by the TBoMS, and the first number determine the second value, and then determine the second time domain resource according to L and the second value. The second value is, for example, the number of repetitions of L. Of course, this is only one of the methods, or the UE can also directly determine the second time domain resource according to L, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first number, without going through The process of determining the second value. The process that needs to determine the second value is described below.

For example, the second value is represented by K, and the UE determines the second value according to L, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first number, for example, a determination method is as follows:

K＝M+N×(first quantity)/L (Formula 1)

Wherein, M represents the number of uplink time slots occupied by the TBoMS, N represents the number of special time slots occupied by the TBoMS, and the first number is the number of symbols used to bear the TBoMS in the special time slot.

In addition, the UE determines the second time domain resource according to the first value and the second value, for example, a determination method is:

Q＝L×K (Formula 2)

Q represents the second time domain resource, and it can be understood that Q represents the number of symbols included in the second time domain resource. For example, L=10, the number of special time slots occupied by TBoMS is 3, the number of uplink time slots occupied by TBoMS is 5, and the number of symbols used to carry TBoMS in special time slots is 2, then according to the formula 1, K=5+3×2/10=5.6, Q=56.

If L=14, when calculating according to formula 1, the first quantity/L may obtain an indivisible value, so the process of rounding up or rounding down can be additionally added, that is to say, formula 1 can Further updated to:

in,

Indicates that x is rounded down. Alternatively, Equation 1 can be further updated as:

in,

Indicates that x is rounded up.

Whether rounding up or rounding down is used can be determined by the UE itself, or configured by a network device, or predefined by a protocol.

For example, L=14, the number of special time slots occupied by the TBoMS is 3, the number of uplink time slots occupied by the TBoMS is 5, and the number of symbols used to carry the TBoMS in the special time slots is 2. According to formula 3, then

According to Formula 2, Q=70 can be obtained. Or, if following Equation 4, then

According to Formula 2, Q=84 can be obtained.

In addition, Equation 3 and Equation 4 take the rounding of K as an example. Alternatively, it is not necessary to round when calculating K (for example, it can be calculated by formula 1), but it can be rounded when calculating Q. For example, formula 1 can be used when calculating K, and modified formula 2 can be used when calculating Q. The modified formula 2 for example

Alternatively, the modified Equation 2 is, for example,

For example, L=14, the number of special time slots occupied by TBoMS is 3, the number of uplink time slots occupied by TBoMS is 5, and the number of symbols used to carry TBoMS in special time slots is 1, then according to formula 1, ,

If combined with the formula

Then Q=73, or, if combined with the formula

Then Q=73.

Optionally, the UE determines the second time domain resource according to L, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first number. The number of occupied uplink time slots, the number of special time slots occupied by TBoMS, and the first number determine a second value, and then determine a second time domain resource according to L and the second value. In this manner, the UE does not need to use L when determining the second value, which can reduce the number of parameters on which the second value depends. Of course, this is only one of the methods, or the UE can also directly determine the second time domain resource according to the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first number, without going through the process of determining the second time domain resource. value process. The process that needs to determine the second value is described below.

For example, the second value is represented by K, and the UE determines the second value according to the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first number. For example, a determination method is as follows:

K＝M+N×(first quantity)/14 (Formula 5)

Wherein, M represents the number of uplink time slots occupied by the TBoMS, N represents the number of special time slots occupied by the TBoMS, and the first number is the number of symbols used to bear the TBoMS in the special time slot. 14 This constant is predefined for a protocol, or pre-configured for a network device, for example. Or the constant in Formula 5 can also be understood as a constant b, and the value of the constant b in Formula 5 is 14 as an example, or the constant b can also have other values.

In addition, the UE determines the second time domain resource according to the first value and the second value, and the determination method may continue to refer to Formula 2.

Q represents the second time domain resource, and it can be understood that Q represents the number of symbols included in the second time domain resource. Because L=14, when calculating according to formula 5, the first quantity/14 may get an indivisible value, so the process of rounding up or rounding down can be additionally added, that is to say, formula 5 can Further updated to:

in,

Indicates that x is rounded down. Alternatively, Equation 5 can be further updated as:

in,

Indicates that x is rounded up.

In addition, Equation 6 and Equation 7 take the rounding of K as an example. Alternatively, it is not necessary to round when calculating K (for example, it can be calculated by formula 5), but it can be rounded when calculating Q. For example, formula 5 can be used when calculating K, and modified formula 2 can be used when calculating Q. The modified formula 2 can refer to the previous introduction.

For example, L=10, the number of special time slots occupied by TBoMS is 3, the number of uplink time slots occupied by TBoMS is 5, and the number of symbols used to carry TBoMS in a special time slot is 1, then according to formula 5, it can be known ,

If combined with the formula

Then Q=52, or, if combined with the formula

Then Q=53.

When the special bearer TBoMS is introduced, the number of time slots occupied by TBoMS or ToT increases, but the number of symbols increases very little. For example, L=14, the ratio of symbols in the special time slot is, downlink symbols:flexible symbols:uplink symbols=10:2:2. If TBoMS occupies a special time slot, it will cause the number of special time slots occupied by TBoMS to increase by 1, but the actual number of symbols added is only 2, that is, through the special time slot, TBoMS is only equivalent to occupying 2/L more =Resources that can be provided by 1/7 uplink time slots. For example, TBoMS occupies a special time slot and an uplink time slot, L=10, if the second time domain resource is calculated directly by multiplying L and the number of time slots occupied by TBoMS, then the calculation result is the second time domain resource 10*2=20 symbols are included. But in fact, TBoMS only occupies 10 symbols in the uplink time slot and 2 symbols in the special time slot, that is, TBoMS only occupies 12 symbols. It can be seen that the calculation deviation is relatively large. Therefore, in the embodiment of the present application, for the case where the TBoMS occupies a special time slot, it may be considered to count the resources occupied by the TBoMS in the special time slot as decimals, which improves the accuracy of the determined time domain resources. Continuing to use the above example, according to the method of the embodiment of the present application, according to formula 1, K=1+1×2/10=1.2, and according to formula 2, Q=12 can be obtained. It can be seen that, through the method provided by the embodiment of the present application, the determined second time domain resource can be closer to the actual situation and more accurate.

Optionally, the UE determines the second time domain resource according to the first value and the number of uplink time slots occupied by TBoMS. Another way is: the UE determines the second time domain resource according to L and the number of uplink time slots occupied by TBoMS. Domain resources. Optionally, the first value is 14, or other values, such as positive integers smaller than 14. For the manner in which the UE determines the number of uplink time slots occupied by the TBoMS, reference may be made to the foregoing introduction. That is to say, TBoMS may or may not occupy special time slots. No matter whether TBoMS occupies special time slots or not, when determining the second time domain resources, special time slots are not included in the calculation process. According to the uplink of TBoMS resources The number of time slots only needs to determine the second time domain resources. The second time domain resources determined in this manner may be less than the time domain resources actually occupied by the first transport block, so the amount of data that can be carried determined according to such second time domain resources is small, and The first transmission block actually occupies more time-domain resources, so more time-domain resources only need to carry a smaller amount of data, so the code rate of the first transmission block can be reduced.

Or, optionally, there is another implementation of S302. This implementation is that the UE determines the second time domain resource according to L and the number of uplink time slots occupied by TBoMS; or, the UE determines the second time domain resource according to L and the first time domain The number of time slots capable of carrying L symbols in the resource determines the second time domain resource. In this implementation mode, the determination method of the second time domain resource can refer to formula 2. K in formula 2 indicates the number of uplink time slots occupied by TBoMS, or indicates that L symbols can be carried in the first time domain resource The number of time slots.

The difference between this implementation method and the previous optional method is that in this implementation method, L can be greater than 14, or it can be understood that L is the number of symbols occupied by TBoMS in multiple time slots occupied, Alternatively, L is the number of symbols occupied by the first ToT of the TBoMS in the multiple time slots occupied. In this case, L includes the number of symbols occupied by the TBoMS in one or more slots. Since the number of symbols occupied by TBoMS in a special time slot is not many, and these symbols have been included in L, when determining the second time domain resource, the number of special time slots occupied by TBoMS can no longer be considered, but The number of uplink time slots occupied by the TBoMS (or the number of time slots capable of carrying L symbols in the first time domain resource) may be considered. This implementation can also be understood as that the resources occupied by TBoMS in a special time slot (for example, the number of symbols occupied by TBoMS in a special time slot) will be included in the determination process of the second time domain resource, and the number of special time slots It is not included in the determination process of the second time domain resource.

For example, if L>14, the initial time domain position of the first time domain resource is located in a special time slot. At this time, if the time domain resource occupied by a ToT of TBoMS is to be calculated, then K can be the first ToT of TBoMS including The number of consecutive uplink time slots; or, if the time domain resource occupied by TBoMS is to be calculated, K may be the total number of uplink time slots included in TBoMS.

Since L has already considered the situation of multiple time slots, the calculation process of K is relatively simple, which is beneficial to simplify the calculation process of the second time domain resource.

In addition, optionally, if TBoMS occupies a special time slot, and the network device has not configured the frequency domain resources used to transmit the physical uplink shared channel (PUSCH) in the special time slot, or the network device has not configured the special The frequency domain resource used to transmit the first transport block in the time slot, then the frequency domain resource used to transmit PUSCH in the special time slot occupied by TBoMS is the same as the frequency domain resource corresponding to the first symbol of the uplink time slot. The time slot is the next time slot after the special time slot, and the first symbol of the uplink time slot is also occupied by TBoMS. The effect of this is that the first symbol in the special time slot and the uplink time slot continuous with the special time slot can be in the same frequency domain position, which is convenient for combining the special time slot and the uplink time slot continuous with the special time slot. The DMRS carried by the slot performs channel estimation.

Further, in each embodiment of the present application, after determining the second time domain resource, the UE may also determine the resource element (resource element, RE) occupied by the TBoMS according to factors such as the second time domain resource and the frequency domain resource occupied by the TBoMS , so that the first transport block is sent through the determined RE. This process will not be described in detail here and below.

Through the technical solutions provided by the embodiments of the present application, a method for determining the time domain resources occupied by the TBoMS under the condition that the TBoMS occupies a special time slot is given, so that the TBoMS mode can be implemented. And when calculating the K value, the calculation result can be a decimal, so that the calculation result is more accurate. Or when calculating the K value, the number of special time slots may not be involved in the calculation, thereby simplifying the calculation process.

In the embodiment shown in FIG. 3, it is introduced that the network device can configure the number of time slots included in the first time domain resource, which may cause a problem that the time slots included in the first time domain resource configured by the network device The number of slots may not necessarily be the number of time slots actually occupied by TBoMS. For example, the number of time slots configured by the network device may include downlink time slots. If the UE determines the number of time slots based on the number of time slots configured by the network device The second time domain resource may lead to an inaccurate determination result of the UE. For this reason, the embodiment of the present application provides a second communication method. By this method, even if the number of time slots included in the first time domain resource configured by the network device is inaccurate, the time domain resource determined by the UE to be occupied by the TBoMS can also be More accurate.

Please refer to FIG. 4 , which is a flowchart of the method.

S401. The network device sends first configuration information to the UE. Correspondingly, the UE receives first configuration information from the network device.

The first configuration information may configure the number of time slots included in the first time domain resource. The first time domain resource is, for example, a time domain resource used by the UE to send a transport block to be transmitted (for example, called a first transport block) to the network device, and the first time domain resource includes multiple time slots. Optionally, the first configuration information may also configure the initial time domain position of the first time domain resource. Alternatively, the first configuration information does not need to configure the initial time domain position of the first time domain resource, and the UE may determine the initial time domain position of the first time domain resource according to the scheduling signaling. For this, reference may be made to the S301 of the embodiment.

In this embodiment of the present application, the number of time slots included in the first time-domain resource configured by the first configuration information is, for example, the number of first-type time slots included in the first time-domain resource. The first type of time slots included in the so-called first time domain resource includes all time slots occupied by the first time domain resource from the start time domain position to the end time domain position of the first time domain resource, for example, includes The first time domain resource is N consecutive time slots starting from the initial time domain position, where N is an integer greater than or equal to 2. For example, the first type of time slot included in the first time domain resource may include one or more of uplink time slots, special time slots or downlink time slots. It can be understood that, according to the TDD ratio, the start time domain position of the first time domain resource, and the end time domain position of the first time domain resource, all time slots spanned by the first time domain resource can be determined. The downlink time slot may be included in the slot, and the UE cannot occupy the downlink time slot when sending the first transport block, but the number of time slots included in the first time domain resource configured by the network device will still be included in the downlink time slot. That is to say, the number of time slots that TBoMS can actually occupy may be less than or equal to the number of time slots configured in the first configuration information, that is, the number of time slots configured in the first configuration information may be inaccurate Yes, the embodiment of this application considers that it cannot be used directly.

For more details about S401, refer to S301 in the embodiment shown in FIG. 3 .

S402. The UE determines according to the initial time domain position of the first time domain resource and the number of time slots included in the first time domain resource, and according to TDD configuration information (for example, TDD configuration) and/or first information Second time domain resource.

For example, the UE can determine the number of uplink time slots occupied by the TBoMS according to the initial time domain position of the first time domain resource, the TDD ratio, and the number of time slots included in the first time domain unit configured in the first configuration information. The number, and the number of special time slots occupied by the TBoMS can be determined with reference to the introduction of the embodiment shown in FIG. 3 . The UE then determines the second time domain according to the first value, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the number of symbols used to carry the first transport block in the special time slot resource. Alternatively, the UE may determine the number of uplink time slots occupied by the TBoMS according to the initial time domain position of the first time domain resource, the TDD configuration, and the number of time slots included in the first time domain unit configured in the first configuration information. number, the UE determines the second time-domain resource according to the number of uplink time slots occupied by the TBoMS according to the first value. For this part of the content, reference may be made to the introduction of the embodiment shown in FIG. 3 .

For example, referring to FIG. 5A , the number of time slots included in the first time domain resource indicated by the first configuration information is 4. The configured number of time slots included in the time domain unit determines that the 4 time slots include one uplink time slot, two downlink time slots, and one special time slot. Then the UE determines that these two downlink time slots cannot be used as actually included time slots, so the UE can determine that the number of uplink time slots included in the first time domain resource is 1, and the number of special time slots included in the first time domain resource The number is 1. The UE can further determine the second time domain resource according to the method introduced in the embodiment shown in FIG. 3 .

Optionally, in addition to possibly excluding some time slots according to the TDD ratio, there may also be some abandonment criteria. According to the abandonment criteria, some time slots also need to be excluded. The abandonment criteria can be used to determine unavailable time slots in time domain resources. Alternatively, some symbols can be excluded according to the abandonment criterion, that is, the abandonment criterion can be used to determine the unavailable symbols in the time domain resources. In the following introduction process, the abandonment criterion is used to determine the unavailable slots in the time domain resources as an example. For example, a waiver criterion is that the network device sends the first information, for example, the network device sends the first information before the start time domain position of the first time domain resource used to transmit the first transport block, and the first information may indicate one or Multiple time slots are unavailable, or the first information does not directly indicate that one or more time slots are unavailable, but the UE can determine that the TBoMS cannot occupy the one or more time slots according to the first information. After receiving the first information, the UE can determine that some time slots are unavailable, and these time slots may include one or more of uplink time slots, downlink time slots, or special time slots. If these time slots include uplink time slots and/or special time slots, TBoMS cannot occupy these time slots, and these time slots should not be included in the calculation process of the second time domain resources. Therefore, if there is a abandonment criterion, the UE can configure the number of time slots included in the first time domain resource according to the initial time domain position of the first time domain resource, the TDD ratio, the abandonment criterion, and the first configuration information , the number of uplink time slots included in the first time domain resource and the number of special time slots included in the first time domain resource may be determined. For the determination method, refer to the introduction of the embodiment shown in FIG. 3 . Then, according to the first value, the number of uplink time slots included in the first time domain resource, the number of special time slots included in the first time domain resource, and the number of symbols used to carry the first transport block in the special time slot number to determine the second time domain resource. Or, if there is a abandonment criterion, the UE may configure the number of time slots included in the first time domain resource according to the initial time domain position of the first time domain resource, the TDD ratio, the abandonment criterion, and the first configuration information The number of uplink time slots included in the first time domain resource may be determined, and the UE determines the second time domain resource according to the first value and the number of uplink time slots included in the first time domain resource. For this part of the content, reference may be made to the introduction of the embodiment shown in FIG. 3 .

Optionally, the first information is, for example, dynamic signaling. For example, the dynamic signaling may be used to indicate the cancellation of uplink transmission of some or all time slots (or symbols) in the first time domain resource, or in other words, the dynamic signaling indicates the cancellation of one or more time slots (or, symbols), the one or more time slots (or, symbols) cannot be used for TBoMS. For another example, the dynamic signaling may be used to schedule sending of the second transport block on some or all time slots (or symbols) included in the first time domain resource, or in other words, the dynamic signaling may be used to schedule one or more time slots (or, symbols) for uplink transmission, and the transmission is the second transport block except the first transport block, then the one or more time slots (or, symbols) cannot be used for TBoMS; or, the The dynamic signaling may be used to schedule the sending of the second transport block on some or all of the time slots (or symbols) included in the first time domain resource, uplink transmission of one or more time slots (or symbols), and the transmitted is the second transport block except the first transport block, and the priority of the second transport block is higher than that of the first transport block, then the one or more time slots (or symbols) cannot be used for TBoMS. For another example, the dynamic signaling may indicate a time slot format, and the time slot format may indicate the format of the time slots included in the first time domain resource, for example, the time slot format may indicate various types of time slots included in the first time domain resource ( including one or more of uplink time slots, downlink time slots or special time slots), and can also indicate the use of flexible symbols in special time slots, for example, indicating that flexible symbols in special time slots are used for uplink transmission or downlink transmission; or, the time slot format may indicate the use of various types of time slots included in the first time domain resource, for example, for uplink transmission or downlink transmission; or, the time slot format may indicate the various types of time slots included in a time slot Symbol positions where symbols (including one or more of downlink symbols, flexible symbols, or uplink symbols) are respectively located. For example, the time slot format indicates that some or all of the flexible symbols in one or more special time slots that should be occupied by TBoMS are used as downlink symbols, then TBoMS can no longer occupy these flexible symbols. Dynamic signaling is considered a form of waiver criteria. The dynamic signaling is, for example, downlink control information (DCI) or cancellation indication (cancellation indication, CI), or other types of dynamic signaling.

Or, optionally, the first information is, for example, a random access response (random access response, RAR). For example, if the RAR is used to indicate access denial, then the UE obviously cannot send the first transport block on the next time domain resource, so the first information is regarded as a kind of abandonment criterion.

For example, referring to FIG. 5B , taking the discarding criterion as the first information as an example (S402 is also taken as an example), where T1 indicates the moment when the network device sends the first information, and the time included in the first time domain resource indicated by the first configuration information The number of slots is 4, and the UE determines the 4 time slots according to the initial time domain position of the first time domain resource, the TDD ratio, and the number of time slots included in the time domain unit configured in the first configuration information. The slots include one special time slot, two uplink time slots, and one downlink time slot. Then the UE determines that this downlink time slot cannot be used as a time slot actually occupied by the TBoMS. In addition, the first information indicates, for example, that the second uplink time slot of the two uplink time slots is unavailable, and then the UE determines according to the first information that the second uplink time slot cannot be used as a time slot actually occupied by the TBoMS. In this way, the UE may determine that the number of uplink time slots included in the first time domain resource is 1, and the number of special time slots included in the first time domain resource is 1. The UE can further determine the second time domain resource according to the method introduced in the embodiment shown in FIG. 3 .

In the embodiment of the present application, besides the dynamic signaling sent by the network device, the renunciation criterion may also have other implementation forms. For example, the abandonment criterion may also be a PUCCH used to schedule uplink control information, and the uplink control information scheduled by the PUCCH needs to occupy part or all of the time slots (or symbols) included in the first time domain resource, then TBoMS can no longer occupy these time slot (or, symbol), so the PUCCH is regarded as a discard criterion. Or, the uplink control information scheduled by the PUCCH needs to occupy part or all of the time slots (or symbols) included in the first time domain resource, and the priority of the uplink control information is higher than the priority of the first transport block. In this case, TBoMS can no longer occupy these time slots (or symbols), so the PUCCH is regarded as a abandonment criterion; and if the priority of the uplink control information is lower than the priority of the first transport block, TBoMS can still continue These slots (or, symbols) are occupied, in which case the PUCCH may not be considered as a dropout criterion.

Optionally, if too many time slots of the TBoMS are occupied due to the abandonment criterion, the available resources of the TBoMS will be reduced, which may affect the transmission quality of the TBoMS. Therefore, in order to further ensure the number of resources when transmitting TBoMS, it can be stipulated that when scheduling TBoMS, the UE does not expect the dynamic signaling of the network equipment to make the uplink time slot and/or special time within the range of TBoMS or the first ToT range of TBoMS The slot is not available, or the UE does not expect dynamic signaling so that the TBoMS cannot be transmitted in the available time slot where the TBoMS is located. Or it may be stipulated that when scheduling TBoMS, the UE does not expect the dynamic signaling of the network equipment after the first moment to make the uplink time slots and/or special time slots within the TBoMS range or within the first ToT range of the TBoMS unavailable, or, The UE does not expect the dynamic signaling after the first moment to make the available time slot where the TBoMS is located unable to transmit the TBoMS. Or it may be stipulated that within the first range, the UE does not expect the dynamic signaling of the network equipment to make the uplink time slots and/or special time slots within the TBoMS range or within the first ToT range of the TBoMS unavailable, or, within the first range Within , the UE does not expect dynamic signaling so that the TBoMS cannot be transmitted in the available time slot where the TBoMS is located. Optionally, the first range is, for example, the time domain range where the first ToT of the TBoMS is located, or the first range is, for example, the entire time domain range occupied by the TBoMS, or the first range may also be other time domain ranges. Optionally, the first range may also be related to a redundancy version (Redundancy Version, RV). For example, compared with other RV versions, RV0 and RV3 carry some system bits, which are more important. For such RV version information The number of resources needs to be guaranteed, and the number of resources is not expected to be reduced, so the first range may be the range corresponding to RV0 and/or RV3. Of course, this is just an example, and the first range is not limited thereto. This specification is configured, for example, by a network device or can also be predefined by a protocol. For network devices, in the presence of this provision, dynamic signaling may not be sent or reduced (for example, dynamic signaling including the first information may not be sent or reduced), so as to minimize the occupation of TBoMS resources and improve TBoMS transmission quality.

For more implementation details of the embodiment of the present application, reference may be made to the introduction of the embodiment shown in FIG. 3 .

In this embodiment of the application, in order to prevent the number of time slots configured by the network device from being accurate enough, the UE can re-determine the number of uplink time slots occupied by TBoMS and/or the number of special time slots, and The number of uplink time slots and/or the number of special time slots determine the second time domain resources, so that the determined second time domain resources are more accurate.

In the process of introducing the embodiment of the present application, the combination of the embodiment of the present application and the embodiment shown in Figure 3 has been introduced. In addition, the embodiment shown in Figure 3 can also be combined with the embodiment of the present application technical solutions. For example, in the embodiment shown in FIG. 3, the number of uplink time slots occupied by TBoMS and/or the number of special time slots occupied by TBoMS may be based on the initial time domain position of the first time domain resource and the first The number of time slots included in the first time domain resource configured by the configuration information, and determined according to the TDD ratio and/or the first information, that is, in the embodiment shown in FIG. 3 , the number of uplink time slots occupied by the TBoMS The number and/or the number of special time slots occupied by the TBoMS can be determined by using the method described in the embodiment of this application.

In the embodiment shown in FIG. 4, it is introduced that the number of time slots included in the first time domain resource configured by the network device may be the number of the first type of time slots, or there is another possibility that the first time domain resource configured by the network device includes the number of time slots of the first type. The number of time slots included in the time domain resources may be the number of the second type of time slots, and the second type of time slots may not include downlink time slots. That is to say, in the embodiment shown in FIG. 4 , the number of time slots for the UE to actually send the first transport block may be less than or equal to the number of time slots configured by the network device, and if the network device configures the second type The number of time slots, then the number of time slots of the first transport block actually sent by the UE should be equal to the number of time slots configured by the network device. But even in this case, the abandonment criterion needs to be considered, otherwise the second time domain resources determined by the UE may not be accurate enough. To this end, the embodiment of the present application provides a fourth communication method, please refer to FIG. 6 , which is a flowchart of the method.

S601. The network device sends first configuration information to the UE. Correspondingly, the UE receives first configuration information from the network device.

In this embodiment of the present application, the number of time slots included in the first time-domain resource configured by the first configuration information is, for example, the number of second-type time slots included in the first time-domain resource. The so-called second-type time slots, for example, do not include downlink time slots, or it can be understood that the second-type time slots included in the first time domain resources may include the first time domain resources from the start time domain position to the end time domain All the time slots occupied up to the position except the downlink time slot.

For more details about S601, refer to S301 in the embodiment shown in FIG. 3 .

S602. The UE determines the second time domain resource according to the number of time slots included in the first time domain resource, or the UE determines the second time domain resource according to the number of time slots included in the first time domain resource and first information.

For example, the UE may determine the second time domain resource according to the number of time slots included in the first time domain resource configured by the first configuration information. Because the number of time slots configured in the first configuration information is the number of time slots of the second type, the UE can directly use the number of time slots configured in the first configuration information when determining the second time domain resource. For example, the UE may determine the number of uplink time slots occupied by the TBoMS according to the initial time domain position of the first time domain resource and the number of time slots included in the first time domain resource configured in the first configuration information, and determine For the determination method of the number of special time slots occupied by the TBoMS, refer to the introduction of the embodiment shown in FIG. 3 . The UE then determines the second time domain according to the first value, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the number of symbols used to carry the first transport block in the special time slot resource. Alternatively, the UE may determine the number of uplink time slots occupied by the TBoMS according to the initial time domain position of the first time domain resource and the number of time slots included in the first time domain unit configured in the first configuration information, and the UE then According to the first value, the number of uplink time slots occupied by the TBoMS is used to determine the second time domain resource. Optionally, the premise of such processing by the UE is, for example, that the abandonment criterion is not considered (for the abandonment criterion, refer to the introduction of the embodiment shown in FIG. 4 ), or there is no abandonment criterion although the abandonment criterion is considered. For this part of the content, reference may be made to the introduction of the embodiment shown in FIG. 3 .

Alternatively, the UE may determine the second time domain resource according to the number of time slots included in the first time domain resource and the first information (this is an example where the abandonment criterion is realized through the first information), and the implementation of the first information, etc. Reference may be made to the introduction of the embodiment shown in FIG. 4 . Optionally, the premise of the UE's processing in this way is, for example, that the renunciation criterion is considered and there is a renunciation criterion. If there is a abandonment criterion, the UE can determine the uplink occupied by the TBoMS according to the initial time domain position of the first time domain resource, the abandonment criterion, and the number of time slots included in the first time domain resource configured in the first configuration information The number of time slots, or determine the number of uplink time slots occupied by the TBoMS and the number of special time slots occupied by the TBoMS. In the case of a abandonment criterion, there may be different ways for the UE to determine the number of uplink time slots (or special time slots) occupied by the TBoMS. For example, one manner is, if the abandonment criterion indicates that n time slots (or, symbols) in the first time domain resource are unavailable, then determine that TBoMS does not occupy these n time slots (or, symbols), where n is a positive integer . That is to say, if the abandonment criterion indicates that a certain uplink time slot (or special time slot) is unavailable, the UE determines that the uplink time slot (or special time slot) does not belong to an available time slot occupied by TBoMS, that is, the UE determines The number of time slots occupied by the TBoMS can be reduced by 1. Further, the UE may exclude the value after n according to the number of time slots included in the first time domain resource (it can be understood as the value obtained after subtracting n from the number of time slots included in the first time domain resource) A second time domain resource is determined.

For example, referring to FIG. 7A, for example, TBoMS will occupy 1 special time slot and 2 uplink time slots, and it is determined that the second uplink time slot is unavailable according to the abandonment criterion. The abandonment criterion is, for example, the first time slot sent by the network device in FIG. a message. The UE determines that the TBoMS no longer occupies the second uplink time slot according to the abandonment criterion, so that the UE can determine that the number of uplink time slots occupied by the TBoMS is 1. For example, the TBoMS shown in FIG. 7A is the final TBoMS. FIG. 7A also includes an uplink time slot on the far right, which does not belong to the TBoMS. In this way, the position of the TBoMS remains unchanged, which is consistent with the position indicated by the network device, which helps to keep the network device and UE unified, and reduces the impact on resources occupied by subsequent services.

For another example, another way is that if the abandonment criterion indicates that the second time slot (or, the second symbol) in the first time domain resource is not available, then the UE determines that the TBoMS does not occupy the second time slot (or, the second symbol) ), but the UE may cause the TBoMS to occupy the third slot (or, the third symbol), and the third slot (or, the third symbol) is located after the second slot (or, the second symbol). The number of time slots (or, symbols) included in the second time slot (or, the second symbol) is n, and the number of time slots (or, symbols) included in the third time slot (or, symbols) is n, and n is positive integer. That is to say, if the abandonment criterion indicates that a certain uplink time slot (or special time slot) is not available, the UE determines that the uplink time slot (or special time slot) does not belong to the time slot occupied by the TBoMS, but the UE can use the TBoMS The end time domain position moves backward, for example, the moved TBoMS can occupy the first uplink time slot (or special time slot) after the end of the original TBoMS to supplement the occupied time slot. Further, the UE determines the second time domain resource according to the number of time slots (or, symbols) included in the first time domain resource, where the first time domain resource does not include the second time slot (or, second symbol), And including the third time slot (or, the third symbol), the second time slot (or, the second symbol) and the number of the time slots (or, the symbols) included in the third time slot (or, the third symbol) are equal is n, the second time slot is an unavailable time slot (or, symbol) indicated by the first information, and the third time slot (or, the third symbol) is located after the second time slot (or, the second symbol).

For example, referring to FIG. 7B , for example, TBoMS will occupy 1 special time slot and 2 uplink time slots, and the second uplink time slot is determined to be unavailable according to the abandonment criterion, then the UE determines that TBoMS will no longer occupy the second uplink time slot, but The UE can move the end time domain position of TBoMS backwards, so that TBoMS occupies the first uplink time slot after the end of the original TBoMS, that is, the rightmost uplink time slot in Figure 7B, such as the TBoMS shown in Figure 7B It is the TBoMS after moving, so that the UE can determine that the number of uplink time slots occupied by the TBoMS is still 2. In this way, the end time domain position of the TBoMS may change, but the resource number of the TBoMS may not change, which can reduce the impact on the TBoMS transmission quality.

Regardless of which of the above methods is adopted, the UE determines the number of uplink time slots occupied by the TBoMS and the number of special time slots occupied by the TBoMS. For the determination method, refer to the introduction of the embodiment shown in FIG. 3 . The UE then determines the second time slot according to the first value, the number of uplink time slots occupied by the TBoMS, the number of special time slots occupied by the TBoMS, and the number of symbols used to carry the first transport block in the special time slot. Domain resources. Alternatively, the UE determines the number of uplink time slots occupied by the TBoMS, and then determines the second time domain resource by using the number of uplink time slots occupied by the TBoMS according to the first value. For this part of the content, reference may be made to the introduction of the embodiment shown in FIG. 3 .

Optionally, if too many time slots of the TBoMS are occupied due to the abandonment criterion, the available resources of the TBoMS will be reduced, which may affect the transmission quality of the TBoMS. Therefore, in order to further ensure the number of resources when transmitting TBoMS, it can be stipulated that when scheduling TBoMS, the UE does not expect the dynamic signaling of the network equipment after the first moment to make the uplink time slots within the range of TBoMS or within the first ToT range of TBoMS And/or the special time slot is unavailable, or the UE does not expect the dynamic signaling after the first moment so that the available time slot where the TBoMS is located cannot transmit the TBoMS. Or it may be stipulated that within the first range, the UE does not expect the dynamic signaling of the network equipment to make the uplink time slots and/or special time slots within the TBoMS range or within the first ToT range of the TBoMS unavailable, or, within the first range Within , the UE does not expect dynamic signaling so that the TBoMS cannot be transmitted in the available time slot where the TBoMS is located. For the introduction of the first range, reference may be made to the embodiment shown in FIG. 4 . This specification is configured, for example, by a network device or can also be predefined by a protocol. For the network device, under the condition that this provision exists, within the first range or after the first moment, no dynamic signaling may be sent or reduced (for example, no dynamic signaling including the first information may be sent or reduced) , minimize the occupation of TBoMS resources, and improve the transmission quality of TBoMS.

For more implementation details of the embodiment of the present application, reference may be made to the introduction of the embodiment shown in FIG. 3 and/or to the introduction of the embodiment shown in FIG. 4 .

In the process of introducing the embodiment of the present application, the combination of the embodiment of the present application and the embodiment shown in Figure 3 has been introduced. In addition, the embodiment shown in Figure 3 can also be combined with the embodiment of the present application technical solutions. For example, in the embodiment shown in FIG. 3, the number of uplink time slots occupied by TBoMS and/or the number of special time slots occupied by TBoMS may be included in the first time domain resource configured according to the first configuration information. The number of time slots is determined, or is determined according to the number of time slots included in the first time domain resource configured by the first information and the first configuration information, that is, the number of time slots occupied by the TBoMS in the embodiment shown in FIG. 3 The number of uplink time slots and/or the number of special time slots occupied by the TBoMS may be determined by using the methods described in the embodiments of this application.

Next consider another question. At present, when sending a transport block, the code rate can be determined from Table 1 according to the modulation and coding scheme (MCS). According to Table 1, the lowest code rate that can be selected is 0.0586. The lower the code rate is, the larger the coverage area is, so it is expected that the code rate can be further reduced. In order to reduce the code rate, the method of repeated transmission can be used at present. For example, a transmission block is transmitted in one time slot, and the transmission block can be transmitted repeatedly through multiple time slots. These repeated transmissions are coded separately, so that repeated The code rate can be reduced once for one transmission. For example, if the transmission is repeated once, the code rate can be reduced from 0.0586 to 1/2 of 0.0586, and if the transmission is repeated once, the code rate can be reduced from 0.0293 to 1/3 of 0.0586. However, although TBoMS occupies multiple time slots, it is not a process of repeated transmission, but a transmission process. These multiple time slots are jointly coded, so the code rate of TBoMS can only be selected from Table 1, that is, , the lowest is 0.0586.

Table 1

The fourth communication method provided by the embodiment of the present application is introduced below, through which the code rate of the TBoMS can be increased. Please refer to FIG. 8 , which is a flowchart of the method.

The second information is the number of time slots included in the first time domain resource. It can be understood that the second information is the number of time slots indicated by the first configuration information; or, the second information is based on the first time domain resource. The number of time slots included and/or the value determined by the initial time domain position of the first time domain resource can be understood as that the second information is the number of time slots indicated according to the first configuration information, and/or The value determined according to the initial time domain position of the first time domain resource. The third value is greater than 1, for example. Optionally, it may be considered that the third value indicates the number of repetitions of the first time-domain resource. The third value is, for example, understood to be the value of the first parameter, and the first parameter may also be called a repetition parameter or an expansion coefficient, or may have other names. The first parameter can be used to reduce the code rate.

The UE determines the second time domain resource according to the second information and the third value. For example, in one manner, the UE determines the second value according to the second information and the third value, and then determines the second time domain resource according to the first value and the second value. resource. The first value is the number of repetitions of symbols allocated to the PUSCH, for example, the first value is L, for L, reference may be made to the introduction of the foregoing embodiment, and the second value is the number of repetitions of L. Alternatively, the UE may directly determine the second time domain resource according to the second information and the third value, without going through the calculation process of the second value.

Taking UE needs to determine the second value as an example, for example, the second value can satisfy:

As another example, the second value may satisfy:

Wherein, H represents the second value. A represents the second information, and a represents the third value. A can be understood as the first time-domain resource configured by the first configuration information in any one of the embodiments shown in FIG. 3 , the embodiment shown in FIG. 4 , or the embodiment shown in FIG. 6 The number of time slots included, or, A may also be K in any one of the embodiments shown in FIG. 3 , the embodiment shown in FIG. 4 , or the embodiment shown in FIG. 6 . Therefore, A may be an integer or a decimal.

Further, the UE may determine the second time domain resource according to formula 2 in the foregoing embodiments, or determine the number of symbols included in the second time domain resource, and at this time, replace K in formula 2 with H.

Or, the UE determines the second time domain resource according to the second information and the third value, for example, one way is:

Another example, another way is:

That is, it is not necessary to round H separately, but just round Q. As for whether to use formula 8 (or formula 9) and formula 2, or formula 10 or formula 11, it can be configured by the network device or predefined by the protocol.

For example, a=3 means that the number of repetitions is 3, so that H is about 1/3 of K, that is to say, the number of symbols occupied by the calculated second time-domain resource (for example, called the number of theoretical symbols) is smaller than that of the first time-domain resource. Second, the number of symbols actually occupied by time-domain resources (for example, the actual number of symbols) is small, for example, the number of theoretical symbols is 1/3 of the actual number of symbols. Then according to the number of theoretical symbols, the amount of data that can be carried on the theoretical symbols is relatively small, and it is not the theoretical symbols that are actually used to carry these data, but the actual symbols. The number of actual symbols is greater than the number of theoretical symbols. , a smaller amount of data is carried by more resources, thereby reducing the code rate of these data (for example, the first transport block). For example, in the case of determining the code rate according to the number of actual symbols, the determined code rate is 0.0586. Taking a=3 as an example, if the code rate is determined according to the theoretical symbols, the determined code rate will be reduced to 0.0586. 1/3. It can be seen that the code rate of the TBoMS can be effectively reduced and the coverage of the TBoMS can be improved through the method provided by the embodiment of the present application.

Or, to reduce the bit rate of TBoMS, another method can be used. For example, TBoMS is regarded as multiple transmissions, and one ToT is regarded as one transmission. When calculating the second time domain resource, the time domain resource occupied by a ToT may be calculated, and the calculation method may refer to the embodiment shown in FIG. 3 , the embodiment shown in FIG. 4 or the embodiment shown in FIG. 6 . Each ToT can be coded separately. In this way, if the number of ToTs included in TBoMS is greater than 1, for example, the number of ToTs included in TBoMS is P, and P is an integer greater than 1, then the overall code rate of TBoMS can be reduced to TBoMS only includes 1/P of the code rate in the case of a ToT. For example, if TBoMS includes only one ToT, the corresponding code rate is 0.0586. If the TBoMS includes 2 ToTs, the overall code rate of the TBoMS can be reduced to 0.0293; if the TBoMS includes 3 ToTs, the overall code rate of the TBoMS can be reduced to 0.0195, and so on. Through this separate encoding method, an effect similar to repeated transmission can be achieved, thereby achieving the purpose of reducing the code rate.

To sum up, the embodiment of the present application can reduce the code rate of the TBoMS, thereby improving the coverage of the TBoMS.
