Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on July 9, 2021, with application number 202110776637.X and application name “A communication method, terminal and network device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0004] When sending a transport block (TB), it is generally transmitted over a time slot. Before sending a transport block, the resources occupied by the transport block must be calculated. Currently, the number of symbols occupied by a transmission is specified to be less than or equal to 14, which is the maximum number of orthogonal frequency division multiplexing (OFDM) symbols that can be provided in a time slot.

[0005] To achieve lower bit rates when transmitting data, a model called "one transmission block over multiple slots" (TBoMS) has been proposed. This involves carrying a single transmission block across multiple time slots. Because TBoMS encompasses multiple time slots, existing methods for calculating the resources occupied by TBoMS cannot be used. Currently, no solution has been found for calculating the resources occupied by TBoMS. This inability to calculate the resources occupied by TBoMS can render TBoMS transmission solutions unfeasible. Summary of the Invention

[0006] Embodiments of the present application provide a communication method and device for providing a method for calculating resources occupied by a TBoMS.

[0007] In a first aspect, a first communication method is provided, which can be executed by a terminal device, or by a larger device including the terminal device, or by a chip system or other functional module, the chip system or functional module being capable of realizing the functions of the terminal device, the chip system or functional module being, for example, arranged in the terminal device. The method comprises: receiving first configuration information from a network device, the first configuration information being used to configure the number of time domain resource units included in a first time domain resource, the first time domain resource including a plurality of time domain resource units; determining a second time domain resource based on the first value and the number of uplink time domain resource units included in the first time domain resource, the second time domain resource being the time domain resource occupied by the first transmission block to be sent, the first time domain resource including one or more special time domain resource units, and the first value being the number of sub-time domain resource units allocated to the PUSCH.

[0008] In the embodiment of the present application, the time domain resources occupied by the first transmission block (TB) can be determined based on the first value and the number of uplink time domain resource units. The time domain resources used to send the first transmission block include multiple time domain resource units. It can be understood that the first transmission block is sent via TBoMS. In other words, the technical solution provided by the embodiment of the present application can calculate the time domain resources occupied by TBoMS, enabling the implementation of the TBoMS transmission solution.

[0009] In combination with the first aspect, in a first optional implementation of the first aspect, the second time domain resource is determined according to the first value and the number of uplink time domain resource units included in the first time domain resource, including: determining the second time domain resource according to the first value, the number of uplink time domain resource units included in the first time domain resource, the number of special time domain resource units included in the first time domain resource, and the number of sub-time domain resource units used to carry the first transmission block in the special time domain resource unit. Through the technical solution provided in the embodiment of the present application, a method for determining the time domain resources occupied by TBoMS when TBoMS occupies special time domain resources is given, so that the TBoMS method can be carried out. And when determining the second time domain resource, the intermediate calculation result can also be a decimal, so that the calculation result is more accurate.

[0010] In combination with the first optional implementation of the first aspect, in the second optional implementation of the first aspect, the second time domain resource is determined according to the first value, the number of uplink time domain resource units included in the first time domain resource, the number of special time domain resource units included in the first time domain resource, and the number of sub-time domain resource units used to carry the first transmission block in the special time domain resource unit, including: determining a second value according to the first value, the number of uplink time domain resource units included in the first time domain resource, the number of special time domain resource units included in the first time domain resource, and the number of sub-time domain resource units used to carry the first transmission block in the special time domain resource unit, the second value is the number of repetitions of the first value; determining the second time domain resource according to the first value and the second value. When determining the second time domain resource, the second value can be determined first, and then the second time domain resource can be determined according to the first value and the second value. And when determining the second value, the determination result can be a decimal, so that the result is more accurate. Alternatively, when determining the second time domain resource, the second value may not be experienced, but the second time domain resource may be determined directly based on the first value, the number of uplink time domain resource units included in the first time domain resource, the number of special time domain resource units included in the first time domain resource, and the number of sub-time domain resource units in the special time domain resource unit for carrying the first transmission block, without any restrictions on the calculation process.

[0011] In combination with the first optional implementation manner of the first aspect or the second optional implementation manner of the first aspect, in the third optional implementation manner of the first aspect, the number of uplink time domain resource units included in the first time domain resource and / or the number of special time domain resource units included in the first time domain resource are determined based on the starting time domain position of the first time domain resource and the number of time domain resource units included in the first time domain resource, as well as based on time division duplex configuration information and / or first information; or, the number of uplink time domain resource units included in the first time domain resource and / or the number of special time domain resource units included in the first time domain resource are determined based on the number of time domain resource units included in the first time domain resource; or, the number of uplink time domain resource units included in the first time domain resource and / or the number of special time domain resource units included in the first time domain resource are determined based on the number of time domain resource units included in the first time domain resource and the first information. Wherein, the first information is used to determine unavailable time domain resource units in the first time domain resource.

[0012] The number of time domain resource units included in the first time domain resource configured by the first configuration information, for example, is the number of first-category time domain resource units included in the first time domain resource. The so-called first-category time domain resource units included in the first time domain resource include all time domain resource units occupied by the first time domain resource from the starting time domain position to the ending time domain position of the first time domain resource. In other words, the number of time domain resource units configured by the first configuration information may be inaccurate and cannot be directly used in embodiments of the present application. Therefore, the number of uplink time domain resource units and / or special time domain resource units included in the first time domain resource used by the UE to determine the second time domain resource can be determined based on the starting time domain position of the first time domain resource and the number of time domain resource units included in the first time domain resource, as well as based on the time division duplex configuration information and / or the first information. The time division duplex configuration can be used to determine the downlink time domain resource unit, and the first information can be used to determine the unavailable time domain resource unit. Both the downlink time domain resource unit and the unavailable time domain resource unit need to be excluded. Therefore, the number of uplink time domain resource units and / or the number of special time domain resource units determined in this way is more accurate. Alternatively, the number of time domain resource units included in the first time domain resource configured by the network device may be the number of the second type of time domain resource units, and the second type of time domain resource units may not include the downlink time domain resource unit. Then the number of uplink time domain resource units and / or the number of special time domain resource units can also be determined based on the number of time domain resource units included in the first time domain resource. Alternatively, even if the number of time domain resource units included in the first time domain resource configured by the network device is the number of second-type time domain resource units, the first information may still exist. Therefore, the number of uplink time domain resource units and / or the number of special time domain resource units can also be determined based on the number of time domain resource units included in the first time domain resource and the first information, which can make the determination result more accurate.

[0013] In combination with the first aspect or any one of the optional embodiments from the first optional embodiment to the third optional embodiment of the first aspect, in the fourth optional embodiment of the first aspect, the starting time domain position of the first time domain resource is located in the first time domain resource unit, wherein the first time domain resource unit is the special time domain resource unit, or the first time domain resource unit is the first uplink time domain resource unit after the special time domain resource unit. The starting time domain position of the first time domain resource configured by the network device may be located in the special time domain resource unit, or it may be the first uplink time domain resource unit after the special time domain resource unit. If it is the first uplink time domain resource unit after the special time domain resource unit, then optionally, the UE may change the starting time domain position of the TBoMS, for example, changing the starting time domain position of the TBoMS to start from the special time domain resource unit, thereby making full use of the resources.

[0053] TBoMS, that is, carrying a transport block (actually carrying a coded transport block) on the resources of multiple time slots, aims to use a lower bit rate when sending the transport block by integrating the resources on multiple time slots, thereby improving coverage.

[0054] TBoMS is a higher-level transmission concept, and further has a lower-level transmission granularity, which is called the transmission occasion of TBoMS (ToT), that is, a ToT is understood as a transmission opportunity of TBoMS. A TBoMS may contain one or more ToTs, while a ToT only contains continuous uplink transmissions. Continuous uplink transmission can be understood as containing two or more continuous uplink time slots, or containing a special time slot plus one or more continuous uplink time slots, and the special time slot is also continuous with the uplink time slot. For example, refer to Figure 1 , is a schematic diagram of TBoMS and ToT. Figure 1 In the embodiment, TBoMS includes two ToTs, wherein the first ToT includes one special time slot plus one uplink time slot, and the second ToT includes one special time slot plus two uplink time slots.

[0055] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plural" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. For example, A / B means: A or B. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0056] The ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish between multiple objects, and are not used to limit the size, content, order, timing, priority or importance of multiple objects. For example, the first information and the second information can be the same information or different information, and this name does not indicate the difference in content, size, priority or importance of the two information. In addition, the numbering of the steps in the various embodiments introduced in this application is only to distinguish different steps, and is not used to limit the order between the steps. For example, step S301 may occur before step S302, or may occur after S302, or may occur at the same time as S302.

[0061] This application embodiment provides a first communication method, see Figure 3 , which is the flow chart of this method. In the following introduction, this method is applied to Figure 2 The network architecture shown in the figure is taken as an example. The terminal device described below is, for example, Figure 2 The terminal device in the network architecture shown in FIG. 1 , the first network device described below is, for example, Figure 2 Network devices in the network architecture shown.

[0062] S301: A network device sends first configuration information to a UE. Correspondingly, the UE receives the first configuration information from the network device.

[0063] The first configuration information can configure the number of time domain resource units 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 transmission block to be transmitted (for example, called the first transmission block) to the network device, but the first time domain resource may not be the time domain resource actually used by the UE to send the first transmission block, 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 to send the first transmission block. The first time domain resource includes multiple time domain resource units. The 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. Among them, the first transmission block can occupy the uplink time domain resource unit and some sub-time domain resource units within the special time domain resource unit, and cannot occupy the downlink time domain resource unit and the remaining sub-time domain resource units within the special time domain resource unit. In other words, the time domain resource units included in the first time domain resource indicated by the first configuration information may be all occupied by the first transmission block, or the first transmission block may only occupy some of the time domain resource units.

[0064] The time domain resource unit is, for example, a subframe, a time slot, a mini-slot or an OFDM symbol (also referred to as a symbol). Taking the time domain resource unit as a time slot as an example, this transmission method can be considered as a TBoMS method. In addition, the embodiments of the present application will also involve 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 time units of the same type. For example, if the time domain resource unit is a time slot, the special time domain resource unit is a special time slot, the uplink 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 unit is obtained by further dividing the time domain resource unit. For example, it is 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, a mini time slot or a symbol, etc.; for another example, if the time domain resource unit is a time slot, the sub-time domain resource unit is, for example, a symbol, etc. For ease of understanding, in the introduction of the embodiments of the present application and the subsequent embodiments, the time domain resource unit is a time slot, the special time domain resource unit is a special time slot, the uplink time domain resource unit is an uplink time slot, the downlink time domain resource unit is a downlink time slot, the sub-time domain resource unit is a symbol, and the transmission method is a TBoMS method. In other words, the time slots described in the embodiments of the present application and the subsequent embodiments can be replaced with time domain resource units, special time slots can be replaced with special time domain resource units, uplink time slots can be replaced with uplink time domain resource units, downlink time slots can be replaced with downlink time domain resource units, and symbols can be replaced with sub-time domain resource units.

[0065] Optionally, the first configuration information may also configure the starting time domain position of the first time domain resource. Alternatively, the first configuration information may not necessarily configure the starting time domain position of the first time domain resource. For example, the network device may also send scheduling signaling to the UE, and the scheduling signaling may be, for example, downlink control information (DCI), or other signaling. The scheduling signaling may schedule the first transmission block. The UE may determine that the first transmission block needs to be sent when the first duration starting from the time slot in which the scheduling signaling is received arrives. The first duration is the time interval between the UE receiving the scheduling signaling and sending the transmission block, and is known to the UE. In other words, the UE can determine the starting time domain position of the first time domain resource based on the moment of receiving the scheduling signaling, without the need for the first configuration information configuration.

[0066] For example, a network device sends a radio resource control (RRC) signaling to a UE, and the RRC signaling may indicate multiple configuration information, of which the first configuration information is one. Each of the multiple configuration information may indicate the number of time slots included in the time domain resource, and optionally, may also indicate the starting 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 within a time slot, the time slot being the starting time slot of the time domain resource, and the symbol being the starting symbol of the time domain resource. The number of time slots included in the time domain resources indicated by different configuration information may be the same or different, and / or the starting time domain positions of the time domain resources indicated by different configuration information may be the same or different. For example, in the RRC signaling, multiple configuration information is included in the time domain resource allocation (TDRA), and the TDRA is presented in the form of a table or multiple entries. If presented in the form of a table, each row of the table may be understood as one configuration information, and if presented in the form of multiple entries, each entry may be understood as one configuration information. Alternatively, multiple configuration information may be presented in RRC signaling in other forms.

[0067] If this is the case, the network device may further send a first signaling to the UE. The first signaling may be, for example, dynamic signaling, such as DCI, and 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 signalings. In other words, the RRC signaling may include multiple configuration information, and the first configuration information is indicated by the first signaling, so that the UE can clearly know 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.

[0068] 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 need to send the first signaling to the UE. In this case, the first configuration information in S301 may be considered to be included in the RRC signaling.

[0069] Optionally, the above RRC signaling may also be replaced by other types of signaling, such as a media access control (MAC) control element (CE).

[0070] TBoMS may occupy a special time slot, which may include uplink symbols, downlink symbols, and flexible symbols. The symbols that can be used to send uplink information include uplink symbols and some flexible symbols (for example, this part of flexible symbols is the flexible symbols remaining in all flexible symbols included in the special time slot, excluding the flexible symbols used for uplink and downlink conversion). In other words, not all 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 resources occupied by TBoMS, or to determine the time domain resources 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 can also 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 TBoMS in the special time slot, or the first configuration information can also configure the number of symbols used to carry the first transmission block in the special time slot. For example, the number of symbols used to carry the TBoMS in the special time slot configured by the first configuration information is the first number. If the TBoMS occupies multiple special time slots, the first number configured by 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 within the TBoMS, or the first number configured by the first configuration information may also be the number of symbols occupied in any special time slot within the TBoMS.

[0071] Alternatively, the first configuration information may not configure the first quantity, and the first quantity may be determined by the UE. For example, the first quantity is the number of symbols occupied in a special time slot included in the first ToT in the time domain within the TBoMS. The starting time domain position of the first time domain resource is, for example, located in the first time slot. The first time slot may be a special time slot included in a ToT in the time domain within the TBoMS. The UE can determine the first quantity based on the starting time domain position of the first time domain resource. Alternatively, in the case where the first configuration information does not configure the first quantity, if the first time slot is not a special time slot but an uplink time slot, and the starting time domain position of the first time domain resource is located at the first symbol of the first time slot, and the time slot before the first time slot is a special time slot, the UE can still determine the number of symbols occupied by the TBoMS in the special time slot (at this time, it is understood that if according to the first configuration information, the TBoMS does not occupy any symbols in the special time slot, but the UE can move the starting time domain position of the first time domain resource forward by itself, so that the TBoMS occupies one or more symbols in the special time slot, or in other words, change the starting time domain position of the TBoMS to be located in the special time slot to make full use of resources), and this number is also the first number. For example, the first number at this time includes all uplink symbols in the special time slot, and the remaining flexible symbols in the special time slot except for the flexible symbols used for uplink and downlink conversion. In this way, when the UE determines the time domain resources occupied by TBoMS, the special time slots not indicated by the network device are also included in the calculation process. However, since this calculation method is only used when the TBoMS method is used for transmission, if the TBoMS method is not used for transmission, it is not necessary to use this method to determine the time domain resources occupied by the transmission. Therefore, this calculation method does not affect the existing method of determining time domain resources under non-TBoMS methods.

[0072] S302. The UE determines the second time domain resource based on 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 based on the first value and the number of uplink time domain resource units occupied by the TBoMS (or the first transmission block). The second time domain resource is the time domain resource occupied by the transmission block to be sent by the UE (for example, called the first transmission block). In other words, the UE determines the time domain resource occupied by the TBoMS (i.e., the second time domain resource) based on 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 the starting time domain position forward as described in the aforementioned steps, the first time domain resource here refers to the time domain resource occupied by the TBoMS after the UE moves the starting time domain position. The first time domain resource here can be generally understood as the time domain resource configured by the network device for sending the first transmission block. The second time domain resource is a time domain resource used by the UE to send the first transmission 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.

[0073] The first value is represented by L, for example, where L is understood to be the number of sub-time domain resource units allocated to a physical uplink shared channel (PUSCH). The first value can be configured through first configuration information, or the first value can also be predefined through a protocol, or preconfigured in a network device and a UE. 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.

[0074] Optionally, the UE determines the second time domain resource based on the first value and the number of uplink time domain resource units occupied by TBoMS. One way is: the UE determines the second time domain resource based on L, the number of uplink time slots included in the first time domain resource (or more accurately, the number of uplink time slots occupied by TBoMS), the number of special time slots included in the first time domain resource (or more accurately, the number of special time slots occupied by TBoMS), and the first quantity. Optionally, the first value is 14, or it can be other values, such as positive integers less than 14. For example, the UE determines the time slot range occupied by TBoMS, or the range of the time domain resource, based on the number of time slots included in the first time domain resource indicated by the first configuration information, and / or based on the starting time domain position of the first time domain resource, thereby determining the number of uplink time slots occupied by TBoMS and the number of special time slots occupied by TBoMS. Alternatively, the UE determines the time slot range occupied by the first ToT of the TBoMS, or the range of the first ToT of the time domain resource, based on the number of time slots included in the first time domain resource indicated by the first configuration information, and / or based on the starting time domain position of the first time domain resource, so as to determine the number of uplink time slots occupied by the ToT and the number of special time slots occupied by the ToT. At this time, the number of uplink time slots occupied by the TBoMS for determining the second time domain resource may refer to the number of uplink time slots occupied by the ToT, and the number of special time slots occupied by the TBoMS for determining the second time domain resource may refer to the number of special time slots occupied by the ToT.

[0075] For example, the UE can determine the range of the first time domain resource based on the starting 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 duplexing (TDD) ratio, or determine the starting time domain position and the ending time domain position of the first time domain resource. The unit of the determined ending time domain position can be a symbol or a time slot. Based on the TDD 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 ratio can indicate the configuration ratio of the uplink time slot, the downlink time slot, and the special time slot.

[0076] In a possible implementation, the number of uplink time slots participating in the determination of the second time domain resources in the embodiment of the present application, that is, the number of uplink time slots occupied by the TBoMS, does not necessarily refer to actual uplink time slots, but refers to uplink time slots 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 the TBoMS is located in the first uplink time slot of these 3 uplink time slots, and the TBoMS only occupies part of the symbols of the first uplink time slot, for example, the number of symbols occupied by the 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 the TBoMS is greater than or equal to L. In this case, the UE can determine that the number of uplink time slots participating in the determination of the second time domain resources is 2, not 3, that is, the first uplink time slot is not regarded as an uplink time slot participating in the determination of the second time domain resources. In addition, in the embodiments of the present application, the number of special time slots that participate in determining the second time domain resource, i.e., the number of special time slots occupied by the TBoMS, does not necessarily refer to the actual special time slots, but rather refers to uplink time slots in which the number of symbols occupied by the TBoMS is less than L. For example, the UE determines that the range actually includes three uplink time slots and one special time slot, the starting time domain position of the TBoMS is located in the first uplink time slot of these three uplink time slots, and the TBoMS only occupies a portion of the symbols of the first uplink time slot. For example, the number of symbols occupied by the TBoMS in the first uplink time slot is less than L, while the number of symbols occupied by the TBoMS in the other two uplink time slots is greater than or equal to L. In addition, the number of symbols occupied by the TBoMS in the special time slot is less than L. In this case, the UE can determine that the number of special time slots that participate in determining the second time domain resource is 2, not 1. That is, the first uplink time slot is not considered an uplink time slot that participates in determining the second time domain resource, but is considered a special time slot that participates in determining the second time domain resource. That is to say, in an embodiment of the present application, the number of uplink time slots and the number of special time slots applicable to the UE when determining the second time domain resources occupied by the first transmission block are determined based on the number of symbols occupied by the TBoMS in the corresponding time slot, and do not necessarily refer to the actual uplink time slots and special time slots.

[0077] Optionally, the UE determines the second time domain resource based on L, the number of uplink time slots included in the first time domain resource (or more accurately, the number of uplink time slots occupied by TBoMS), the number of special time slots included in the first time domain resource (or more accurately, the number of special time slots occupied by TBoMS), and the first quantity. For example, one way is that the UE determines the second value based on L, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first quantity, and then determines the second time domain resource based on L and the second value. The second value is, for example, the number of repetitions of L. Of course, this is just one way, or the UE can also directly determine the second time domain resource based on L, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first quantity, without going through the process of determining the second value. The following describes the process of determining the second value.

[0078] For example, the second value is represented by K. The UE determines the second value according to L, the number of uplink time slots occupied by the TBoMS, the number of special time slots occupied by the TBoMS, and the first quantity. For example, one determination method is as follows:

[0079] K=M+N×(first number) / L (Formula 1)

[0080] Here, M represents the number of uplink time slots occupied by TBoMS, N represents the number of special time slots occupied by TBoMS, and the first number is the number of symbols used to carry TBoMS in the special time slot.

[0081] In addition, the UE determines the second time domain resource according to the first value and the second value. For example, one determination method is:

[0082] Q=L×K(Formula 2)

[0083] Q represents the second time domain resource, which can be understood as 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 the special time slot is 2. According to Formula 1, K = 5 + 3 × 2 / 10 = 5.6, and Q = 56.

[0084] If L=14, then when calculating according to Formula 1, the first number / L may result in an indivisible value. Therefore, an additional rounding-up or rounding-down process may be added. That is, Formula 1 can be further updated as follows:

[0085]

[0086] in, Indicates that x is rounded down. Alternatively, Formula 1 can be further updated as:

[0087]

[0088] in, Indicates rounding x upwards.

[0089] Whether to use rounding up or rounding down can be determined by the UE itself, or configured by the network device, or predefined by the protocol.

[0090] 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 the special time slot is 2. If according to formula 3, According to formula 2, we can get Q = 70. Or, according to formula 4, According to formula 2, we can get Q=84.

[0091] In addition, Formula 3 and Formula 4 are based on the example of rounding K. Alternatively, rounding is not necessary when calculating K (for example, Formula 1 can be used), but rounding is allowed when calculating Q. For example, Formula 1 can be used when calculating K, and a modified Formula 2 can be used when calculating Q. The modified Formula 2 is, for example, Alternatively, the modified formula 2 is, for example,

[0092] 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 the special time slot is 1. According to formula 1, If we combine the formula Then Q = 73, or, if we combine the formula Then Q=73.

[0093] Optionally, the UE determines the second time domain resource based on L, the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first quantity. For example, another method is that the UE determines the second value based on the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first quantity, and then determines the second time domain resource based on L and the second value. In this way, 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 based on the number of uplink time slots occupied by TBoMS, the number of special time slots occupied by TBoMS, and the first quantity, without going through the process of determining the second value. The following describes the process of determining the second value.

[0094] For example, the second value is represented by K. The UE determines the second value according to the number of uplink time slots occupied by the TBoMS, the number of special time slots occupied by the TBoMS, and the first quantity. For example, one determination method is as follows:

[0095] K=M+N×(first number) / 14 (Formula 5)

[0096] Here, M represents the number of uplink timeslots occupied by the TBoMS, and N represents the number of special timeslots occupied by the TBoMS. The first quantity is the number of symbols used to carry the TBoMS in the special timeslot. The constant 14 is, for example, predefined in the protocol or preconfigured by the network equipment. Alternatively, the constant in Formula 5 can be understood as constant b. Formula 5 uses the value 14 as an example, but constant b can also have other values.

[0097] In addition, the UE determines the second time domain resource according to the first value and the second value. The determination method can continue to refer to Formula 2.

[0098] Q represents the second time domain resource, which can be understood as Q representing the number of symbols included in the second time domain resource. Because L = 14, when calculating according to Formula 5, the first number / 14 may result in an indivisible value, so an additional rounding up or rounding down process can be added. In other words, Formula 5 can be further updated as follows:

[0099]

[0100] in, Indicates that x is rounded down. Alternatively, Formula 5 can be further updated as:

[0101]

[0102] in, Indicates rounding x upwards.

[0103] Whether to use rounding up or rounding down can be determined by the UE itself, or configured by the network device, or predefined by the protocol.

[0104] In addition, Formulas 6 and 7 are examples of rounding K. Alternatively, rounding is not necessary when calculating K (for example, Formula 5 can be used), but rounding is permitted when calculating Q. For example, Formula 5 can be used to calculate K, while a modified Formula 2 can be used to calculate Q. The modified Formula 2 can be referred to in the previous section.

[0105] 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 the special time slot is 1. According to formula 5, If we combine the formula Then Q = 52, or, if we combine the formula Then Q=53.

[0106] When the special bearer TBoMS is introduced, the number of timeslots occupied by the TBoMS or ToT increases, but the increase in the number of symbols is minimal. For example, if L = 14, the symbol ratio in the special timeslot is downlink symbols: flexible symbols: uplink symbols = 10:2:2. If a TBoMS occupies a special timeslot, the number of special timeslots occupied by the TBoMS increases by 1, but the actual number of symbols increased is only 2. That is, through the special timeslot, the TBoMS only occupies 2 / L = 1 / 7 of the resources available in the uplink timeslot. For example, if a TBoMS occupies one special timeslot and one uplink timeslot, L = 10. If the second time domain resource is calculated directly by multiplying L by the number of timeslots occupied by the TBoMS, the result is that the second time domain resource includes 10 × 2 = 20 symbols. However, in reality, the TBoMS only occupies 10 symbols in the uplink timeslot and 2 symbols in the special timeslot, that is, the TBoMS only occupies 12 symbols. As can be seen, the calculation error is relatively large. Therefore, in the embodiment of the present application, when a TBoMS occupies a special time slot, the resources occupied by the TBoMS in the special time slot can be counted as a decimal, thereby improving the accuracy of the determined time domain resources. Continuing with the above example, if the method of the embodiment of the present application is used, then according to Formula 1, K = 1 + 1 × 2 / 10 = 1.2, and according to Formula 2, Q = 12. It can be seen that the method provided by the embodiment of the present application can make the determined second time domain resources closer to the actual situation and more accurate.

[0107] Optionally, the UE determines the second time domain resource based on the first value and the number of uplink time slots occupied by the TBoMS. Another approach is for the UE to determine the second time domain resource based on L and the number of uplink time slots occupied by the TBoMS. Optionally, the first value is 14, or may be another value, such as a positive integer less than 14. Regarding the method by which the UE determines the number of uplink time slots occupied by the TBoMS, please refer to the previous description. That is, the TBoMS may or may not occupy special time slots. Regardless of whether the TBoMS occupies special time slots, when determining the second time domain resource, the special time slots are not included in the calculation process. The second time domain resource is determined based on the number of uplink time slots of the TBoMS resources. In this manner, the second time domain resource determined may be less than the time domain resource actually occupied by the first transport block. In this case, the amount of data that can be carried based on such second time domain resource is smaller, while the first transport block actually occupies more time domain resources. Consequently, the more time domain resources only need to carry less data, thereby reducing the code rate of the first transport block.

[0108] Alternatively, optionally, S302 may be implemented in another manner, in which the UE determines the second time domain resource based on L and the number of uplink time slots occupied by the TBoMS; or the UE determines the second time domain resource based on L and the number of time slots in the first time domain resource that can carry L symbols. In this implementation, the method for determining the second time domain resource may refer to Formula 2, where K in Formula 2 represents the number of uplink time slots occupied by the TBoMS or the number of time slots in the first time domain resource that can carry L symbols.

[0109] The difference between this implementation and the previous optional implementation is that in this implementation, L can be greater than 14, or it can be understood that L is the number of symbols occupied by TBoMS in the multiple time slots occupied, or L is the number of symbols occupied by the first ToT of TBoMS in the multiple time slots occupied. In this case, L includes the number of symbols occupied by TBoMS in one or more time slots. Since the number of symbols occupied by TBoMS in the special time slot is not large, and these symbols have been included in L, when determining the second time domain resources, the number of special time slots occupied by TBoMS can no longer be considered, but the number of uplink time slots occupied by TBoMS (or the number of time slots in the first time domain resources that can carry L symbols) can be considered. This implementation can also be understood as the resources occupied by TBoMS in the special time slot (for example, the number of symbols occupied by TBoMS in the special time slot) will be included in the determination process of the second time domain resources, while the number of special time slots will not be included in the determination process of the second time domain resources.

[0110] For example, L>14, the starting time domain position of the first time domain resource is located in a special time slot. At this time, if the time domain resources occupied by a ToT of TBoMS are to be calculated, K can be the number of consecutive uplink time slots included in the first ToT of TBoMS; or, if the time domain resources occupied by TBoMS are to be calculated, K can be the total number of uplink time slots included in TBoMS.

[0111] Since L has taken into account the situation of multiple time slots, the calculation process of K is relatively simple, which is conducive to simplifying the calculation process of the second time domain resources.

[0112] In addition, optionally, if TBoMS occupies a special time slot, and the network device is not configured with frequency domain resources for transmitting the physical uplink shared channel (PUSCH) in the special time slot, or the network device is not configured with frequency domain resources for transmitting the first transmission block in the special time slot, then the frequency domain resources for transmitting PUSCH in the special time slot occupied by TBoMS are the same as the frequency domain resources corresponding to the first symbol of the uplink time slot, and the uplink 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 facilitates channel estimation by combining the DMRS carried by the special time slot and the uplink time slot continuous with the special time slot.

[0113] Furthermore, in various embodiments of the present application, after determining the second time domain resources, the UE may also determine the number of resource elements (REs) occupied by the TBoMS based on factors such as the second time domain resources and the frequency domain resources occupied by the TBoMS, thereby sending the first transport block through the determined REs. This process will not be described in detail here or in the following text.

[0114] The technical solutions provided by the embodiments of this application provide a method for determining the time domain resources occupied by a TBoMS when it occupies special time slots, enabling the implementation of the TBoMS method. Furthermore, when calculating the K value, the result can be a decimal, thereby increasing the accuracy of the calculation. Alternatively, the number of special time slots can be excluded from the calculation of the K value, thereby simplifying the calculation process.

[0115] exist Figure 3 The embodiment shown introduces that the network device can configure the number of time slots included in the first time domain resource. The problem that may arise from this is that the number of time slots included in the first time domain resource configured by the network device may not necessarily be the number of time slots actually occupied by the TBoMS. For example, the number of time slots configured by the network device may include downlink time slots. If the UE determines the second time domain resource based on the number of time slots configured by the network device, the UE's determination result may be inaccurate. To this end, the embodiment of the present application provides a second communication method, through which, 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 occupied by the TBoMS determined by the UE can be relatively accurate.

[0116] Please refer to Figure 4 , which is a flowchart of the method.

[0117] S401: A network device sends first configuration information to a UE. Correspondingly, the UE receives the first configuration information from the network device.

[0118] The first configuration information can 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 transmission block to be transmitted (for example, called the first transmission block) to the network device, and the first time domain resource includes multiple time slots. Optionally, the first configuration information can also configure the starting time domain position of the first time domain resource. Alternatively, the first configuration information does not need to configure the starting time domain position of the first time domain resource. The UE can determine the starting time domain position of the first time domain resource based on the scheduling signaling. For this, please refer to Figure 3 S301 of the embodiment shown.

[0119] In the 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-class time slots included in the first time domain resource. The so-called first-class time slots included in the first time domain resource include all time slots occupied by the first time domain resource from the starting time domain position to the ending time domain position of the first time domain resource, for example, including N consecutive time slots starting from the starting time domain position of the first time domain resource, where N is an integer greater than or equal to 2. For example, the first-class time slots 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 starting time domain position of the first time domain resource, and the ending time domain position of the first time domain resource, all time slots spanned by the first time domain resource can be determined, and these time slots may include downlink time slots. The UE cannot occupy downlink time slots when sending the first transmission 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 slots. 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 by the first configuration information, that is, the number of time slots configured by the first configuration information may be inaccurate, and the embodiment of the present application believes that it cannot be directly used.

[0120] For more information about S401, please refer to Figure 3 S301 in the embodiment shown.

[0121] S402. The UE determines a second time domain resource according to the starting time domain position of the first time domain resource and the number of time slots included in the first time domain resource, as well as TDD configuration information (eg, TDD ratio) and / or the first information.

[0122] For example, the UE can determine the number of uplink time slots occupied by the TBoMS and the number of special time slots occupied by the TBoMS according to the starting 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 by the first configuration information. The determination method can refer to Figure 3 An introduction to the embodiment shown. The UE then determines the second time domain resource based on 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 transmission block in the special time slot. Alternatively, the UE can determine the number of uplink time slots occupied by TBoMS based on the starting 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 by the first configuration information. The UE then determines the second time domain resource based on the first value and the number of uplink time slots occupied by TBoMS. For more information, please refer to Figure 3 Description of the illustrated embodiment.

[0123] For example, reference Figure 5A , the number of time slots included in the first time domain resource indicated by the first configuration information is 4. The UE determines that these 4 time slots include one uplink time slot, two downlink time slots, and one special time slot based on the starting 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 by the first configuration information. Then the UE determines that these two downlink time slots cannot be used as the actual included time slots, so that 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 is 1. The UE further determines that the number of uplink time slots included in the first time domain resource is 1. Figure 3 The method introduced in the illustrated embodiment can determine the second time domain resource.

[0124] Optionally, in addition to excluding some time slots based on the TDD allocation, there may be other abandonment criteria, which also require excluding some time slots. The abandonment criteria can be used to determine unavailable time slots in the time domain resources. Alternatively, some symbols can be excluded based on the abandonment criteria, that is, the abandonment criteria can be used to determine unavailable symbols in the time domain resources. In the following description, the abandonment criteria used to determine unavailable time slots in the time domain resources are used as an example. For example, one abandonment criterion is that the network device sends first information, such as the network device sends first information before the starting time domain position of the first time domain resource used to transmit the first transmission block. The first information may indicate that one or more 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 these one or more time slots based on the first information. After receiving the first information, the UE can determine that some time slots are unavailable. 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, then the TBoMS can no longer 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 determine 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 according to the starting time domain position of the first time domain resource, the TDD ratio, the abandonment criterion, and the number of time slots included in the first time domain resource configured by the first configuration information. The determination method can refer to Figure 3 An introduction to the embodiment shown. The UE then determines the second time domain resource based on 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 transmission block in the special time slot. Alternatively, if there is a abandonment criterion, the UE can determine the number of uplink time slots included in the first time domain resource based on the starting time domain position of the first time domain resource, the TDD ratio, the abandonment criterion, and the number of time slots included in the first time domain resource configured by the first configuration information. The UE then determines the second time domain resource based on the first value and the number of uplink time slots included in the first time domain resource. For this part, please refer to Figure 3 Description of the illustrated embodiment.

[0125] Optionally, the first information is, for example, dynamic signaling. For example, the dynamic signaling may be used to instruct cancellation of uplink transmission of some or all time slots (or symbols) in the first time domain resource. In other words, the dynamic signaling instructs cancellation of uplink transmission of one or more time slots (or symbols), and then these one or more time slots (or symbols) cannot be used for TBoMS. For another example, the dynamic signaling may be used to schedule the sending of a second transmission block on part or all of the time slots (or symbols) included in the first time domain resources, or in other words, the dynamic signaling may be used to schedule uplink transmission of one or more time slots (or symbols), and the transmission is a second transmission block other than the first transmission block, then these one or more time slots (or symbols) cannot be used for TBoMS; or, the dynamic signaling may be used to schedule the sending of a second transmission block on part or all of the time slots (or symbols) included in the first time domain resources, and the uplink transmission of one or more time slots (or symbols), and the transmission is a second transmission block other than the first transmission block, and the priority of the second transmission block is higher than the priority of the first transmission block, then these 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 the configuration ratio of various time slots (including one or more uplink time slots, downlink time slots, or special time slots) included in the first time domain resource, and may also indicate the purpose 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 purpose of various 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 symbol positions of various symbols (including one or more downlink symbols, flexible symbols, or uplink symbols) included in a time slot. For example, the time slot format indicates that some or all of the flexible symbols in one or more special time slots that should have been occupied by the TBoMS are used as downlink symbols, then the TBoMS can no longer occupy these flexible symbols. Therefore, the dynamic signaling indicating the time slot format is regarded as a form of abandonment criteria. The dynamic signaling may be, for example, downlink control information (DCI) or cancellation indication (CI), or may be other types of dynamic signaling.

[0126] Alternatively, the first information is, for example, a random access response (RAR). For example, the RAR is used to indicate access rejection, so the UE obviously cannot send the first transport block on the next time domain resource, and thus the first information is regarded as a kind of abandonment criterion.

[0127] For example, reference Figure 5B, taking the abandonment criterion being the first information as an example (S402 is also taken as an example), T1 represents the moment when the network device sends the first information, and the number of time slots included in the first time domain resource indicated by the first configuration information is 4. The UE determines that these 4 time slots include a special time slot, two uplink time slots, and a downlink time slot based on the starting 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 by the first configuration information. Then the UE determines that this downlink time slot cannot be used as the time slot actually occupied by TBoMS. In addition, if the first information indicates that the second uplink time slot of the two uplink time slots is unavailable, the UE determines that the second uplink time slot cannot be used as the time slot actually occupied by TBoMS based on the first information. In this way, 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 is 1. The UE further determines based on Figure 3 The method introduced in the illustrated embodiment can determine the second time domain resource.

[0128] In the embodiment of the present application, in addition to the dynamic signaling sent by the network device, the abandonment criterion may also have other implementation forms. For example, the abandonment criterion may also be a PUCCH for scheduling uplink control information. 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 resources, so the TBoMS can no longer occupy these time slots (or symbols), so the PUCCH is regarded as an abandonment criterion. Alternatively, 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 resources, and the priority of the uplink control information is higher than the priority of the first transmission block. In this case, the TBoMS can no longer occupy these time slots (or symbols), so the PUCCH is regarded as an abandonment criterion; and if the priority of the uplink control information is lower than the priority of the first transmission block, the TBoMS can still continue to occupy these time slots (or symbols). In this case, the PUCCH may not be regarded as an abandonment criterion.

[0129] Optionally, if too many time slots of TBoMS are occupied due to the abandonment criteria, the resources available to TBoMS will be reduced, which may affect the transmission quality of TBoMS. Therefore, in order to further ensure the amount of resources when transmitting TBoMS, it can be stipulated that, when scheduling TBoMS, the UE does not expect the dynamic signaling of the network device to make the uplink time slots and / or special time slots within the TBoMS range or the first ToT range of TBoMS unavailable, or the UE does not expect the dynamic signaling to make the available time slots where TBoMS is located unable to transmit TBoMS. Alternatively, it can be stipulated that, when scheduling TBoMS, the UE does not expect the dynamic signaling of the network device after the first moment to make the uplink time slots and / or special time slots within the TBoMS range or the first ToT range of TBoMS unavailable, or the UE does not expect the dynamic signaling after the first moment to make the available time slots where TBoMS is located unable to transmit TBoMS. Or it can be stipulated that, within the first range, the UE does not expect the dynamic signaling of the network device to make the uplink time slots and / or special time slots within the TBoMS range or the first ToT range of the TBoMS unavailable, or, within the first range, the UE does not expect the dynamic signaling to make the available time slots where the TBoMS is located unable to transmit the TBoMS. Optionally, the first range is, for example, the time domain range where the first ToT of the TBoMS is located, or, for example, the first range is, for example, the entire time domain range occupied by the TBoMS, or the first range can also be other time domain ranges. Optionally, the first range may also be related to the redundancy version (RV). For example, compared with other RV versions, RV0 and RV3 carry part of the system bits and 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. Therefore, 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 to this. This provision is, for example, configured by the network device, or can also be predefined by the protocol. For network devices, if this provision exists, they may not send or reduce sending of dynamic signaling (for example, not send or reduce sending of dynamic signaling including the first information), so as to minimize the occupation of TBoMS resources and improve the transmission quality of TBoMS.

[0130] For more details about the implementation of the present application, please refer to Figure 3 Description of the illustrated embodiment.

[0131] In an embodiment of the present application, in order to prevent the number of time slots configured by the network device from being inaccurate, the UE can re-determine the number of uplink time slots and / or the number of special time slots occupied by TBoMS, and determine the second time domain resources based on the re-determined number of uplink time slots and / or the number of special time slots occupied by TBoMS, so that the determined second time domain resources are more accurate.

[0132] In the introduction of the embodiment of this application, the embodiment of this application and Figure 3 The embodiments shown are combined in a manner that, in addition, Figure 3 The embodiments shown can also be combined with the technical solutions of the embodiments of this application. For example, Figure 3 In the illustrated embodiment, the number of uplink time slots occupied by the TBoMS and / or the number of special time slots occupied by the TBoMS may be determined according to the starting time domain position of the first time domain resource and the number of time slots included in the first time domain resource configured by the first configuration information, as well as according to the TDD ratio and / or the first information, that is, Figure 3 In the illustrated embodiment, the number of uplink time slots occupied by the TBoMS and / or the number of special time slots occupied by the TBoMS may be determined using the method described in the embodiment of the present application.

[0133] exist Figure 4 In the embodiment shown, the number of time slots included in the first time domain resource configured by the network device may be the number of first-category time slots, or there is another possibility that the number of time slots included in the first time domain resource configured by the network device may be the number of second-category time slots, and the second-category time slots may not include downlink time slots. That is, in Figure 4 In the embodiment shown, the number of time slots in which the UE actually sends the first transmission block may be less than or equal to the number of time slots configured by the network device. If the network device is configured with the number of second-type time slots, then the number of time slots in which the UE actually sends the first transmission block should be equal to the number of time slots configured by the network device. However, even in this case, it is necessary to consider the abandonment criterion, otherwise the second time domain resource 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 Figure 6 , which is a flowchart of the method.

[0134] S601: A network device sends first configuration information to a UE. Correspondingly, the UE receives the first configuration information from the network device.

[0135] The first configuration information can 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 transmission block to be transmitted (for example, called the first transmission block) to the network device, and the first time domain resource includes multiple time slots. Optionally, the first configuration information can also configure the starting time domain position of the first time domain resource. Alternatively, the first configuration information does not need to configure the starting time domain position of the first time domain resource. The UE can determine the starting time domain position of the first time domain resource based on the scheduling signaling. For this, please refer to Figure 3 S301 of the embodiment shown.

[0136] In the 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-category time slots included in the first time domain resource. The so-called second-category time slots, for example, do not include downlink time slots, or it can be understood that the second-category time slots included in the first time domain resource may include all time slots occupied by the first time domain resource from the starting time domain position to the ending time domain position, excluding downlink time slots.

[0137] For more information about S601, please refer to Figure 3 S301 in the embodiment shown.

[0138] 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 the first information.

[0139] For example, the UE can determine the second time domain resource based on 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 by the first configuration information is the number of second-type time slots, the UE can directly use the number of time slots configured by the first configuration information when determining the second time domain resource. For example, the UE can determine the number of uplink time slots occupied by TBoMS and the number of special time slots occupied by TBoMS based on the starting time domain position of the first time domain resource and the number of time slots included in the first time domain resource configured by the first configuration information. The determination method can refer to Figure 3 An introduction to the embodiment shown. The UE then determines the second time domain resource based on 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 transmission block in the special time slot. Alternatively, the UE can determine the number of uplink time slots occupied by TBoMS based on the starting time domain position of the first time domain resource and the number of time slots included in the first time domain unit configured by the first configuration information, and the UE then determines the second time domain resource based on the first value and the number of uplink time slots occupied by TBoMS. Optionally, the premise for the UE to do so is, for example, that the abandonment criteria are not considered (for details about the abandonment criteria, please refer to Figure 4 ), or although abandonment criteria are considered, no abandonment criteria exist. Figure 3 Description of the illustrated embodiment.

[0140] Alternatively, the UE may determine the second time domain resource based on the number of time slots included in the first time domain resource and the first information (this is an example of abandoning the criterion through the first information). For the implementation of the first information, please refer to Figure 4An introduction to the embodiment shown. Optionally, the premise for the UE to process in this way is, for example, that the abandonment criteria are taken into consideration and the abandonment criteria exist. If the abandonment criteria exist, the UE can determine the number of uplink time slots occupied by the TBoMS, or determine the number of uplink time slots occupied by the TBoMS and determine the number of special time slots occupied by the TBoMS based on the starting time domain position of the first time domain resource, the abandonment criteria, and the number of time slots included in the first time domain resource configured by the first configuration information. In the case where the abandonment criteria exist, 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 way is that if the abandonment criteria indicate that n time slots (or symbols) in the first time domain resource are unavailable, it is determined that the TBoMS does not occupy these n time slots (or symbols), where n is a positive integer. That is, 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 the available time slots occupied by the TBoMS, that is, the number of time slots occupied by the TBoMS determined by the UE may be reduced by 1. Furthermore, the UE may determine the second time domain resource based on the value obtained by excluding n from the number of time slots included in the first time domain resource (which can be understood as the value obtained by subtracting n from the number of time slots included in the first time domain resource).

[0141] For example, reference Figure 7A For example, TBoMS will occupy 1 special time slot and 2 uplink time slots. According to the abandonment criterion, it is determined that the second uplink time slot is unavailable. The abandonment criterion is, for example, Figure 7A The first information sent by the network device at time T1. 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 Figure 7A The TBoMS shown is the final TBoMS. Figure 7A The rightmost uplink timeslot is also included, which does not belong to the TBoMS. In this way, the position of the TBoMS remains unchanged and is consistent with the position indicated by the network device, which helps the network device and the UE maintain consistency and reduces the impact on the resources occupied by subsequent services.

[0142] For another example, if the abandonment criterion indicates that the second time slot (or the second symbol) in the first time domain resource is unavailable, 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 time slot (or the third symbol), and the third time slot (or the third symbol) is located after the second time 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 symbol) is n, where n is a positive integer. That is, 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 the time slot occupied by the TBoMS, but the UE may move the end time domain position of the TBoMS backward, for example, the moved TBoMS may 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 based on the number of time slots (or, symbols) included in the first time domain resource, wherein the first time domain resource does not include the second time slot (or, second symbol) and includes the third time slot (or, third symbol), the number of time slots (or, symbols) included in the second time slot (or, second symbol) and the third time slot (or, third symbol) is n, the second time slot is an unavailable time slot (or, symbol) indicated by the first information, and the third time slot (or, third symbol) is located after the second time slot (or, second symbol).

[0143] For example, reference Figure 7B For example, TBoMS will occupy one special time slot and two uplink time slots. According to the abandonment criteria, it is determined that the second uplink time slot is unavailable. Then, the UE determines that TBoMS no longer occupies the second uplink time slot. However, the UE can move the end domain position of TBoMS backward so that TBoMS occupies the first uplink time slot after the original TBoMS ends. That is, Figure 7B The rightmost uplink timeslot in , for example Figure 7B The TBoMS shown in the figure is the moved TBoMS, so the UE can determine that the number of uplink time slots occupied by the TBoMS is still 2. In this way, the end domain position of the TBoMS may change, but the number of TBoMS resources may remain unchanged, which can reduce the impact on the TBoMS transmission quality.

[0144] Regardless of which of the above methods is used, the UE determines the number of uplink time slots occupied by TBoMS and the number of special time slots occupied by TBoMS. The determination method can be referred to Figure 3The UE then determines the second time domain resource based on 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 transmission block in the special time slot. Alternatively, the UE determines the number of uplink time slots occupied by the TBoMS, and then determines the second time domain resource based on the number of uplink time slots occupied by the TBoMS according to the first value. For this part, please refer to Figure 3 Description of the illustrated embodiment.

[0145] Optionally, if too many time slots of TBoMS are occupied due to the abandonment criteria, the resources available to TBoMS will be reduced, which may affect the transmission quality of TBoMS. Therefore, in order to further ensure the amount of resources when transmitting TBoMS, it can be stipulated that when scheduling TBoMS, the UE does not expect the dynamic signaling of the network device after the first moment to make the uplink time slots and / or special time slots within the TBoMS range or the first ToT range of TBoMS unavailable, or the UE does not expect the dynamic signaling after the first moment to make the available time slots where TBoMS is located unable to transmit TBoMS. Or it can be stipulated that, within the first range, the UE does not expect the dynamic signaling of the network device to make the uplink time slots and / or special time slots within the TBoMS range or the first ToT range of TBoMS unavailable, or, within the first range, the UE does not expect the dynamic signaling to make the available time slots where TBoMS is located unable to transmit TBoMS. For an introduction to the first range, please refer to Figure 4 The embodiment shown. This provision is, for example, configured by the network device, or may be predefined by a protocol. For the network device, when this provision exists, dynamic signaling may not be sent or may be reduced (e.g., dynamic signaling including the first information is not sent or is reduced) within a first range or after a first moment, thereby minimizing the use of TBoMS resources and improving the transmission quality of TBoMS.

[0146] For more details about the implementation of the present application, please refer to Figure 3 The description of the embodiments shown, and / or reference to Figure 4 Description of the illustrated embodiment.

[0147] In an embodiment of the present application, in order to prevent the number of time slots configured by the network device from being inaccurate, the UE can re-determine the number of uplink time slots and / or the number of special time slots occupied by TBoMS, and determine the second time domain resources based on the re-determined number of uplink time slots and / or the number of special time slots occupied by TBoMS, so that the determined second time domain resources are more accurate.

[0148] In the introduction of the embodiment of this application, the embodiment of this application and Figure 3 The embodiments shown are combined in a manner that, in addition, Figure 3 The embodiments shown can also be combined with the technical solutions of the embodiments of this application. For example, Figure 3 In the illustrated embodiment, the number of uplink time slots occupied by the TBoMS and / or the number of special time slots occupied by the TBoMS may be determined according to the number of time slots included in the first time domain resource configured by the first configuration information, or according to the first information and the number of time slots included in the first time domain resource configured by the first configuration information, that is, Figure 3 In the illustrated embodiment, the number of uplink time slots occupied by the TBoMS and / or the number of special time slots occupied by the TBoMS may be determined using the method described in the embodiment of the present application.

[0149] Next, consider another question. Currently, when sending a transport block, the code rate can be determined from Table 1 based on the modulation and coding scheme (MCS). Table 1 shows that the lowest selectable code rate is 0.0586. A lower code rate provides greater coverage, so it is desirable to further reduce the code rate. To reduce the code rate, repeated transmissions are currently used. For example, one transport block is transmitted per time slot, and the same block can be retransmitted multiple times across multiple time slots. These retransmissions are encoded separately, so each retransmission reduces the code rate. For example, with one retransmission, the code rate can be reduced from 0.0586 to 1 / 2 of 0.0586. With another retransmission, 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 repeated transmission process, but a single transmission process. These multiple time slots are jointly encoded. Therefore, the code rate for TBoMS can only be selected from Table 1, that is, the lowest 0.0586.

[0150] Table 1

[0151]

[0152] The following describes a fourth communication method provided by an embodiment of the present application, by which the bit rate of TBoMS can be improved. Figure 8 , which is a flowchart of the method.

[0153] S801: A network device sends first configuration information to a UE. Correspondingly, the UE receives the first configuration information from the network device.

[0154] For more information about S801, please refer to Figure 3 S301 of the embodiment shown, or reference Figure 4 S401 of the embodiment shown, or reference Figure 6 S601 of the embodiment shown.

[0155] S802. The UE determines a second time domain resource according to the second information and the third value.

[0156] The second information is the number of time slots included in the first time domain resource, which can be understood as the second information being the number of time slots indicated by the first configuration information; or, the second information is a value determined based on the number of time slots included in the first time domain resource and / or the starting time domain position of the first time domain resource, which can be understood as the second information being the number of time slots indicated by the first configuration information and / or the value determined based on the starting time domain position of the first time domain resource. The third value is, for example, greater than 1. Optionally, the third value can be considered to indicate the number of repetitions of the first time domain resource. The third value is, for example, understood as the value of the first parameter, which can also be called a repetition parameter or an expansion coefficient, or can have other names. The first parameter can be used to reduce the bit rate.

[0157] The UE determines the second time domain resource based on the second information and the third value. For example, one approach is that the UE determines the second value based on the second information and the third value, and then determines the second time domain resource based on the first value and the second value. The first value is the number of repetitions of the number of symbols allocated to the PUSCH. For example, the first value is L. Regarding L, refer to the description of the aforementioned embodiment. The second value is the number of repetitions of L. Alternatively, the UE may directly determine the second time domain resource based on the second information and the third value, without going through the calculation process of the second value.

[0158] For example, the UE needs to determine the second value. For example, the second value may satisfy:

[0159]

[0160] For another example, the second value may satisfy:

[0161]

[0162] Where H represents the second value. A represents the second information, and a represents the third value. A can be understood as Figure 3 The embodiment shown, Figure 4 The embodiment shown or Figure 6 The number of time slots included in the first time domain resource configured by the first configuration information in any of the embodiments shown, or A may also be Figure 3 The embodiment shown, Figure 4 The embodiment shown or Figure 6 K in any of the embodiments shown. Therefore, A may be an integer or a decimal.

[0163] Furthermore, the UE may determine the second time domain resources according to Formula 2 in the aforementioned embodiment, or determine the number of symbols included in the second time domain resources, and in this case, replace K in Formula 2 with H.

[0164] Alternatively, the UE determines the second time domain resource according to the second information and the third value, for example, in one manner:

[0165]

[0166] For example, another way is:

[0167]

[0168] That is, it is not necessary to round H separately, but only Q. Whether to use Formula 8 (or Formula 9) and Formula 2, or Formula 10 or Formula 11, can be configured by the network device or predefined by the protocol.

[0169] For example, a=3 means the number of repetitions is 3, so H is approximately 1 / 3 of K, that is, the calculated number of symbols occupied by the second time domain resource (for example, called the theoretical number of symbols) is less than the number of symbols actually occupied by the second time domain resource (for example, called the actual number of symbols), for example, the theoretical number of symbols is 1 / 3 of the actual number of symbols. Then the amount of data that can be carried on the theoretical symbol determined according to the theoretical number of symbols is relatively small, and the actual symbols are not the theoretical symbols, but the actual symbols. The number of actual symbols is greater than the theoretical number of symbols. By carrying a smaller amount of data with more resources, the code rate of these data (for example, the first transmission block) can be reduced. For example, in the case of determining the code rate based on the actual number of symbols, the determined code rate is 0.0586. Taking a=3 as an example, if the code rate is determined based on the theoretical symbol, the determined code rate will be reduced to 1 / 3 of 0.0586. It can be seen that the method provided by the embodiment of the present application can effectively reduce the code rate of TBoMS and improve the coverage of TBoMS.

[0170] Alternatively, to reduce the bit rate of TBoMS, another method can be used. For example, TBoMS can be regarded as multiple transmissions, and one ToT can be regarded as one transmission. When calculating the second time domain resource, the time domain resource occupied by one ToT can be calculated. The calculation method can refer to Figure 3 The embodiment shown, Figure 4 The embodiment shown or Figure 6The embodiment shown. Each ToT can be encoded separately, so that if the number of ToTs included in the TBoMS is greater than 1, for example, the number of ToTs included in the TBoMS is P, and P is an integer greater than 1, then the overall code rate of the TBoMS can be reduced to 1 / P of the code rate when the TBoMS only includes one ToT. For example, if the TBoMS only includes 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. This separate encoding method can achieve an effect similar to repeated transmission, thereby achieving the purpose of reducing the code rate.

[0171] In summary, the embodiments of the present application can reduce the bit rate of TBoMS, thereby improving the coverage of TBoMS.
