Description

[Technical Field]

[0001] The present disclosure relates to the field of communications technology, and in particular to a frequency hopping method, apparatus, user equipment, base station, and storage medium. [Background technology]

[0002] In a communication system, when uplink slot resources are scarce, uplink TBoMS (Transmission Block processing over multi-slots transmission) transmission is generally performed using uplink symbol resources in special slots allocated by a base station to reduce transmission delay and improve coding efficiency. Furthermore, when intra-slot frequency hopping is initiated in uplink TBoMS transmission in normal slots, it is necessary to initiate intra-slot frequency hopping in uplink TBoMS transmission in special slots. Here, when intra-slot frequency hopping is initiated in uplink TBoMS transmission in special slots, it is necessary to determine the symbol position of each hop in the special slot.

[0003] In the related art, the symbol position of each hop in the special slot is the same as the symbol position of each hop in the normal slot. However, under normal circumstances, the partial symbols preceding the position in the uplink symbol resource of the special slot may be unusable symbols (e.g., downlink symbols or guard symbols for uplink-downlink switching). If the symbol position of each hop in the special slot is determined based on this, the number of unusable symbols in the first hop of the special slot may be large, which may prevent uplink TBoMS transmission in the first hop and result in wasted resources. Summary of the Invention [Problem to be solved by the invention]

[0021]

[0023] The following detailed description of the embodiments of the present disclosure will be given, and examples of the embodiments are shown in the drawings. Here, the same or similar reference numerals throughout the drawings indicate the same or similar elements. The embodiments described below with reference to the accompanying drawings are illustrative and are intended to explain the present disclosure, but cannot be understood as limiting the present disclosure.

[0022] In the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0023] Hereinafter, the frequency hopping method, apparatus, user equipment, base station, and storage medium provided by the present disclosure will be described in detail with reference to the accompanying drawings.

[0024] FIG. 1 is a schematic flowchart of a frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE (User Equipment). As shown in FIG. 1, the frequency hopping method may include the following steps:

[0025] In step 101, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, and a symbol resource for data transmission in a special slot allocated by the base station is obtained.

[0026] Here, in one embodiment of the present disclosure, the symbol resource for data transmission in the special slot allocated by the base station may be the symbol resource for uplink TBoMS transmission in the special slot. Also, in one embodiment of the present disclosure, the symbol resource for uplink TBoMS transmission may include a starting symbol position S and a symbol length L, and the symbol resource for uplink TBoMS transmission may specifically be symbols located at symbol positions [S, S+L-1] in the special slot.

[0027] In addition, in one embodiment of the present disclosure, if the PUSCH (Physical Uplink Shared Channel) mapping type is different, the position and symbol length of the start symbol may be different.

[0028] Specifically, in one embodiment of the present disclosure, when the PUSCH mapping type is type A, the protocol specifies that the starting symbol position S should be the position of the 0th symbol, i.e., S = symbol #0, and the symbol length L may be between [4, 14], i.e., L ∈ [4, 14], and 4≦S+L≦ 14. For example, assuming that when the PUSCH mapping type is type A, the starting symbol position S may be symbol #0 and the symbol length may be 5, it may be determined that the symbol resources for uplink TBoMS transmission allocated by the base station are symbol #0 to symbol #5 of the special slot.

[0029] In another embodiment of the present disclosure, when the PUSCH mapping type is type B, the protocol specifies that the starting symbol position S ∈ [symbol#0, symbol#13] and the symbol length L may be between [1, 14], that is, L ∈ [1, 14], and 1≦S+L≦14. Exemplarily, assuming that when the PUSCH mapping type is type B, the starting symbol position S may be symbol#2 and the symbol length may be 5, it may be determined that the symbol resources for uplink TBoMS transmission allocated by the base station are symbol#2 to symbol#7 of the special slot.

[0030] In one embodiment of the present disclosure, the symbol resource for the uplink TBoMS transmission may be determined by the UE based on parameters set and / or instructed by the base station, where a specific method for determining the symbol resource based on the parameters will be described in detail in subsequent embodiments.

[0031] In step 102, perform intra-slot frequency hopping in the uplink slot, determine available symbols in the special slot, and perform intra-slot frequency hopping on the available symbols in the symbol resource, or do not perform intra-slot frequency hopping in the special slot.

[0032] Here, in one embodiment of the present disclosure, a method for determining usable symbols in a special slot may include determining unusable symbols from the special slot based on SFI (slot format indication) dynamic instruction signaling and / or quasi-static slot format configuration signaling and / or other dynamic instruction signaling and / or other RRC configuration signaling transmitted from a base station, and determining that the usable symbols are symbols other than the unusable symbols in the special slot.

[0033] In one embodiment of the present disclosure, the unusable symbols may include at least one of guard symbols for downlink to uplink switching, downlink symbols for downlink transmission, symbols for transmitting SSBs (Synchronization Signal Blocks), symbols assigned to a CSS (Common Search Space) (e.g., CSS#0), symbols occupied by CIs (Cancel Indications), and symbols for service transmissions with a higher priority than the current data transmission.

[0034] In one embodiment of the present disclosure, if a symbol in a special slot satisfies any one of the above conditions, the symbol is determined to be an unusable symbol.

[0035] It should be noted that in one embodiment of the present disclosure, the time domain resources allocated by the base station in the above step 101 may include unusable symbols. In another embodiment of the present disclosure, the time domain resources allocated by the base station in the above step 101 may not include unusable symbols.

[0036] In one embodiment of the present disclosure, when intra-slot frequency hopping is performed in an uplink slot, intra-slot frequency hopping may be performed only on available symbols in a symbol resource. In another embodiment of the present disclosure, when intra-slot frequency hopping is performed in an uplink slot, intra-slot frequency hopping may not be performed in a special slot.

[0037] In one embodiment of the present disclosure, if intra-slot frequency hopping is not performed in the special slot, the frequency domain location of the special slot is the same as the frequency domain location of any one hop of the uplink slot. For example, in one embodiment of the present disclosure, the frequency domain location of the special slot may be the same as the frequency domain location of the second hop of the uplink slot.

[0038] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0039] FIG. 2 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 2, the frequency hopping method may include the following steps:

[0040] In step 201, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0041] Here, in one embodiment of the present disclosure, whether intra-slot frequency hopping is performed is determined mainly based on the frequency hopping flag bit, the frequency domain resource allocation type (type 1), and the frequency hopping type setting.

[0042] Here, the frequency hopping type is set by the RRC upper layer parameter "frequency hopping", and may be set to intra-slot FH or inter-slot FH, or this parameter does not exist. If this parameter does not exist, intra-slot frequency hopping is not initiated. The frequency domain resource allocation type may be set to {type 1, type 2, dynamic handover} by RRC upper layer signaling, where type 1 is a continuous frequency domain resource allocation scheme and type 2 is a discontinuous frequency domain resource allocation scheme. If set to dynamic handover, the type is determined to be type 1 or type 2 based on the instruction of DCI dynamic signaling, and intra-slot frequency hopping is initiated only if set to or indicated as type 1. The frequency hopping flag bit is dynamically indicated by one bit of DCI signaling, where "1" indicates that intra-slot frequency hopping is possible and "0" indicates that intra-slot frequency hopping is not possible.

[0043] Here, in one embodiment of the present disclosure, the parameters may include at least one of a PUSCH mapping type including type A and type B, a symbol length for data transmission in the special slot, and a starting symbol position for data transmission in the special slot.

[0044] The specific method by which the UE obtains the parameters set and / or instructed by the base station will be described in detail below.

[0045] In one embodiment of the present disclosure, a method for acquiring the parameter "PUSCH mapping type, or symbol length for data transmission in a special slot, or starting symbol position for data transmission in a special slot" may include acquiring it through higher layer signaling transmitted from a base station and dynamic instruction from the base station.

[0046] Specifically, in one embodiment of the present disclosure, a method for obtaining a PUSCH mapping type, a symbol length for data transmission in a special slot, or a starting symbol position for data transmission in a special slot through higher layer signaling transmitted from a base station and dynamic instruction from the base station specifically includes: a UE obtaining a time domain resource allocation table transmitted by the base station through higher layer signaling, where the uplink time domain resource allocation table includes at least one set of time domain resources, each set of time domain resources corresponding to an index, and each set of time domain resources including at least one of a PUSCH mapping type, a symbol length for data transmission in a special slot, and a starting symbol position for data transmission in the special slot; and then obtaining the index dynamically indicated by the base station; and determining a time domain resource matching the index from the time domain resource allocation table based on the dynamically indicated index.

[0047] Illustratively, Table 1 is an uplink time domain resource allocation table provided by one embodiment of the present disclosure.

[0048] [Table 1]

[0049] [Table 2]

[0050] As shown in Table 2, there is a correspondence relationship between the value of μ and the subcarrier spacing of the BWP in which the current transmission is located. The value of u can be determined based on this correspondence relationship and the subcarrier spacing of the BWP in which the current transmission is located. Here, this correspondence relationship is as follows: μ = 0 when the subcarrier spacing is 15 KHZ, μ = 1 when the subcarrier spacing is 30 KHZ, μ = 2 when the subcarrier spacing is 60 KHZ, and μ = 3 when the subcarrier spacing is 120 KHZ. In one embodiment of the present disclosure, the correspondence relationship between the value of μ and the subcarrier spacing of the BWP in which the current transmission is located may be obtained by the base station through RRC upper layer signaling.

[0051] As shown in Tables 1 and 2, there are multiple indexes, and different indexes correspond to different time domain resources. Specifically, the time domain resources corresponding to index=4 include: the PUSCH mapping type is Type B, K2=j, the starting symbol position for data transmission in the special slot is S=2, and the symbol length for data transmission in the special slot is L=10.

[0052] Based on this, in one embodiment of the present disclosure, when the index value dynamically indicated by the base station is 4, the UE can directly determine the PUSCH mapping type, or the symbol length for data transmission in the special slot, or the starting symbol position for data transmission in the special slot based on the parameters. In combination with the above, the UE can successfully acquire the parameters set and / or indicated by the base station.

[0053] Furthermore, in one embodiment of the present disclosure, after the UE obtains parameters set and / or indicated by the base station, it can determine symbol resources for uplink TBoMS transmission in the special slot based on the parameters. Specifically, in one embodiment of the present disclosure, the method for determining symbol resources for uplink TBoMS transmission in the special slot specifically includes determining symbols located between [S, S+L-1] in the special slot as symbol resources for uplink TBoMS transmission.

[0054] In step 202, perform intra-slot frequency hopping in the uplink slot, determine available symbols in the special slot, and directly determine that intra-slot frequency hopping is not performed in the special slot.

[0055] Here, in an embodiment of the present disclosure, the specific method for performing intra-slot frequency hopping in the uplink slot may be a method in the prior art, and the description thereof will be omitted in the embodiment of the present disclosure.

[0056] In step 203, at least one first DMRS (Demodulation Reference Signal) symbol offset value is determined based on parameters set and / or indicated by the base station.

[0057] In addition, in one embodiment of the present disclosure, the parameters set and / or instructed by the base station may further include at least one of a DMRS-Additional Position, the number of DMRS ports, whether to start intra-slot frequency hopping, and a DMRS-type A Position.

[0058] In one embodiment of the present disclosure, the DMRS-type A Position parameter is a parameter for PUSCH mapping type A, and based on this, when the PUSCH mapping type is type B, the DMRS-type A Position parameter is invalid, and when the PUSCH mapping type is type A, the DMRS-type A Position parameter is valid.

[0059] Furthermore, in one embodiment of the present disclosure, the UE can determine whether the symbol type of the DMRS is single-symbol DMRS or dual-symbol DMRS by consulting Table 3 below based on the configuration type of the DMRS and the number of DMRS ports in the above parameters. Here, in one embodiment of the present disclosure, the configuration type of the DMRS can be configured in the UE by the base station via RRC (Radio Resource Control) upper layer parameters. Also, in one embodiment of the present disclosure, the configuration type of the DMRS includes type 1 and type 2.

[0060] [Table 3]

[0061] As shown in Table 1, when the DMRS configuration type is type 1, if the number of ports is four or less, it is determined to be single-symbol DMRS, and if the number of ports is more than four, it is determined to be dual-symbol DMRS. Also, when the DMRS configuration type is type 2, if the number of ports is eight or less, it is determined to be single-symbol DMRS, and if the number of ports is eight or more, it is determined to be dual-symbol DMRS.

[0062] The specific method by which the UE obtains the parameters set and / or instructed by the base station will be described in detail below.

[0063] Specifically, in one embodiment of the present disclosure, a method for obtaining the parameter "DMRS-Additional Position" may include obtaining it through RRC (Radio Resource Control) upper layer signaling transmitted from a base station.

[0064] In one embodiment of the present disclosure, a method for obtaining the parameter "DMRS-type A Position" may include obtaining it through a system broadcast message Master Information Block (MIB) transmitted from a base station.

[0065] In one embodiment of the present disclosure, a method for obtaining the parameter of the number of DMRS ports or whether to start intra-slot frequency hopping includes obtaining the parameter of the number of DMRS ports or whether to start intra-slot frequency hopping dynamically instructed by a base station.

[0066] Here, in one embodiment of the present disclosure, the UE determines at least one first DMRS symbol offset value based on the parameter, where the first DMRS symbol offset value is specifically used to determine the position of the DMRS symbol in the special slot.

[0067] Here, in one embodiment of the present disclosure, if the PUSCH time domain type included in the parameter is different, the method by which the UE determines at least one first DMRS symbol offset value based on the parameter is also different.

[0068] Specifically, in one embodiment of the present disclosure, if the PUSCH time domain type included in the parameters is type B, the UE may determine at least one first DMRS symbol offset value according to a mapping rule of type B.

[0069] In another embodiment of the present disclosure, if the PUSCH time domain type included in the parameters is type A, the UE may determine at least one first DMRS symbol offset value according to a type A mapping rule.

[0070] In another embodiment of the present disclosure, if the PUSCH time domain type included in the parameters is type A, the UE may determine at least one first DMRS symbol offset value according to a type B mapping rule.

[0071] In another embodiment of the present disclosure, when the PUSCH time domain type included in the parameter is type A, the UE can determine at least one first DMRS symbol offset value according to the mapping rule of type B, where the number of DMRS ports in the parameter is single, and the number of available symbols in the special slot is less than four.

[0072] Hereinafter, specific methods for determining at least one first DMRS symbol offset value according to a type A mapping rule and determining at least one first DMRS symbol offset value according to a type B mapping rule will be described in detail.

[0073] Here, in one embodiment of the present disclosure, the method for determining at least one first DMRS symbol offset value according to the type B mapping rule may include the following methods.

[0074] Method 1 determines at least one first DMRS symbol offset value based on the number of available symbols in the symbol resource and other parameters other than the symbol length for data transmission in the special slot within the parameters.

[0075] In the second method, at least one first DMRS symbol offset value is determined based on the symbol length for data transmission in the special slot and other parameters than the symbol length for data transmission in the special slot within the parameters.

[0076] Furthermore, the above methods 1 and 2 will be described in detail.

[0077] First, in an embodiment of the present disclosure, when determining at least one first DMRS symbol offset value using Method 1 and Method 2, a PUSCH DMRS position location table needs to be used, where Table 4 is the first PUSCH DMRS position location table provided by an embodiment of the present disclosure. The UE can obtain at least one first DMRS symbol offset value by querying Table 4 based on parameters.

[0078] [Table 4]

[0079] Here, in one embodiment of the present disclosure, d may be the number of available symbols in the symbol resource. d may be the symbol length for data transmission in the special slot. Based on this, the UE determines l d , PUSCH mapping type, and DMRS-Additional Position, the at least one first DMRS symbol offset value may be determined. d = 10, the PUSCH mapping type is Type B, and DMRS-Additional Position = pos2, then Table 4 can be consulted to determine that at least one DMRS symbol offset value is 10, 4, or 8.

[0080] In one embodiment of the present disclosure, l0 is determined based on the PUSCH mapping type. Specifically, if the PUSCH mapping type is Type A, l0 = DMRS-type A Position. If the PUSCH mapping type is Type B, l0 = 0. Based on this, if mapping is performed based on the Type B mapping rule, l0 = 0.

[0081] Based on this, in one embodiment of the present disclosure, when determining at least one first DMRS symbol offset value using Method 1, the value of l in Table 4 above is d where ∑ is the number of available symbols in the symbol resource. In addition, the step of the UE determining at least one first DMRS symbol offset value using method 1 may include querying Table 4 above and performing DMRS symbol mapping based on the number of available symbols in the symbol resource, the DMRS-Additional Position, and PUSCH mapping Type B to determine the at least one first DMRS symbol offset value.

[0082] In another embodiment of the present disclosure, when determining at least one first DMRS symbol offset value using Method 2, the value of l in Table 4 above is d where x is the symbol length for data transmission in the special slot. In addition, the step of the UE determining at least one first DMRS symbol offset value using method 2 may include querying Table 4 above and performing DMRS symbol mapping based on the symbol length for data transmission in the special slot, the DMRS-Additional Position, and PUSCH mapping Type B to determine the at least one first DMRS symbol offset value.

[0083] In addition, in one embodiment of the present disclosure, the method for determining at least one first DMRS symbol offset value according to the type A mapping rule may include the following methods.

[0084] In a first method, at least one first DMRS symbol offset value is determined based on the number of available symbols in the symbol resource and other parameters other than the symbol length for data transmission in the special slot within the parameter.

[0085] In a second method, at least one first DMRS symbol offset value is determined based on a symbol length for data transmission in the special slot and other parameters than the symbol length for data transmission in the special slot within the parameters.

[0086] Furthermore, the first and second methods will be described in detail.

[0087] First, in one embodiment of the present disclosure, when determining at least one first DMRS symbol offset value using the first method and the second method, both methods need to use the PUSCH DMRS location table shown in Table 4 above, where the UE can obtain at least one first DMRS symbol offset value by querying Table 4 based on the above parameters.

[0088] Here, in one embodiment of the present disclosure, d may be the number of available symbols in the symbol resource. d may be the symbol length for data transmission in the special slot. Based on this, the UE determines l d , PUSCH mapping type, and DMRS-Additional Position, the at least one first DMRS symbol offset value may be determined. d= 10, the PUSCH mapping type is Type A, and DMRS-Additional Position = pos2, then Table 4 can be consulted to determine that at least one DMRS symbol offset value is 10, 6, or 9.

[0089] In one embodiment of the present disclosure, l0 is determined based on the PUSCH mapping type. Specifically, if the PUSCH mapping type is Type A, l0 = DMRS-type A Position. If the PUSCH mapping type is Type B, l0 = 0. Based on this, when mapping is performed based on the Type A mapping rule, l0 = DMRS-type A Position.

[0090] Based on this, in one embodiment of the present disclosure, when determining at least one first DMRS symbol offset value using the first method, d where ∑ is the number of usable symbols in the symbol resource. In addition, the step of the UE determining at least one first DMRS symbol offset value using a first method may include querying Table 4 above and performing DMRS symbol mapping based on the number of usable symbols in the symbol resource, the DMRS-Additional Position, the PUSCH mapping Type A, and the DMRS-type A Position to determine the at least one first DMRS symbol offset value.

[0091] In another embodiment of the present disclosure, when the second method is used to determine at least one first DMRS symbol offset value, dwhere ∑ is the symbol length for data transmission in the special slot. In addition, the UE's step of determining at least one first DMRS symbol offset value using a second method may include querying Table 4 above and performing DMRS symbol mapping based on the symbol length for data transmission in the special slot, the DMRS-Additional Position, the PUSCH mapping Type A, and the DMRS-type A Position to determine the at least one first DMRS symbol offset value.

[0092] Note that, in one embodiment of the present disclosure, before determining the at least one first DMRS symbol offset value, the following method may be further included.

[0093] Step 1 determines the available symbols in the special slot.

[0094] In step 2, the parameters set and / or instructed by the base station are determined.

[0095] Here, in one embodiment of the present disclosure, for detailed explanations of steps 1 and 2, please refer to the related explanations in the above embodiments, and the explanations will be omitted in the embodiment of the present disclosure.

[0096] In step 3, at least one fourth DMRS symbol offset value in the special slot is determined based on the parameters, and the sum of the symbol number of the first symbol in the symbol resource and each fourth DMRS symbol offset value is determined to obtain at least one fourth sum value, and the symbol whose symbol number corresponds to the fourth sum value is determined as the fourth time domain position of the DMRS.

[0097] Here, in one embodiment of the present disclosure, the UE can obtain at least one fourth DMRS symbol offset value by consulting Table 4 above based on the parameters, and when determining the fourth DMRS symbol offset value, ld in Table 4 is the symbol length for data transmission in the special slot. Furthermore, the principle of the method for determining the fourth DMRS symbol offset value is similar to that of the method for determining the first DMRS symbol offset value, so for details, please refer to the above embodiment, and a description thereof will be omitted in the embodiment of the present disclosure.

[0098] In addition, in one embodiment of the present disclosure, after at least one fourth DMRS symbol offset value is determined, the time domain position of the DMRS can be first determined in a special slot using a normal method, specifically, the above step 3 can be performed: "determine the sum of the symbol number of the first symbol in the symbol resource and each fourth DMRS symbol offset value to obtain at least one fourth sum value, and determine the symbol whose symbol number corresponds to the fourth sum value as the fourth time domain position of the DMRS," where this fourth time domain position is the time domain position of the DMRS determined in a special slot using a normal method.

[0099] In step 4, it is determined whether the fourth time domain position satisfies a preset condition, and if it satisfies the preset condition, the above step 203 is executed; if it does not satisfy the preset condition, the above step 5 is executed.

[0100] The preset conditions include at least one of condition 1 that all fourth time-domain positions collide with unusable symbols in the special slot, and condition 2 that none of the fourth time-domain positions are located on usable symbols.

[0101] Here, in one embodiment of the present disclosure, the preset condition may be only one of the above conditions. In another embodiment of the present disclosure, the preset condition may be both of the above conditions. In one embodiment of the present disclosure, when the preset condition is both of the above conditions, the preset condition is satisfied when the fourth time domain position satisfies any one of the preset conditions.

[0102] In addition, in one embodiment of the present disclosure, if the fourth time-domain position meets the preset conditions, it indicates that none of the fourth time-domain positions determined in the normal manner can be used for uplink TBoMS transmission, and the above step 203 needs to be performed to re-determine the DMRS time-domain position; if the fourth time-domain position does not meet the preset conditions, it indicates that there is a time-domain position in the fourth time-domain position that can be used for uplink TBoMS transmission, and thus step 5 can be performed.

[0103] In step 5, the DMRS is transmitted based on a time-domain position located in an available symbol of the special slot in the fourth time-domain position.

[0104] Assume that the unusable symbols in the special slot are symbol #0 to symbol #2, and the determined fourth time domain position is symbol #1, symbol #5, and symbol #9. In this case, the DMRS can be transmitted based on symbol #5 and symbol #9.

[0105] In step 204, determine a time domain location of the DMRS in the special slot based on a first usable symbol of the symbol resources allocated by the base station and at least one first DMRS symbol offset value.

[0106] Here, in one embodiment of the present disclosure, if the method for determining at least one first DMRS symbol offset value in step 203 is different, the method for determining the first time domain position of the DMRS is also different.

[0107] Specifically, when determining at least one first DMRS symbol offset value using method 1 or method 1, the method for determining the first time domain position of the DMRS may include determining the sum of the symbol number of the first usable symbol and each first DMRS symbol offset value to obtain at least one first sum value, and determining the symbol whose symbol number corresponds to the first sum value as the first time domain position of the DMRS.

[0108] For example, in one embodiment of the present disclosure, assuming that at least one first DMRS symbol offset value obtained by method 1 or method 1 in step 201 is l0, 4, 8, and assuming that the symbol number of the first usable symbol in the symbol resource is symbol#1 and l0=0, the determined first time domain position of the DMRS may be symbol#(1+l0)=symbol#(1+0)=symbol#1, symbol#(1+4)=symbol#5, symbol#(1+8)=symbol#9.

[0109] In another embodiment of the present disclosure, when at least one first DMRS symbol offset value is determined using method 2 or method 2 in the above step 201, the symbol length for data transmission in the special slot is greater than the number of usable symbols in the symbol resource, so the determined first DMRS symbol offset value is large; and when the first time-domain position of the DMRS is determined based on the first usable symbol in the symbol resource and the at least one first DMRS symbol offset value, the determined first time-domain position of the DMRS may be a time-domain position beyond the symbol resource, which will affect data transmission.

[0110] Therefore, in one embodiment of the present disclosure, when determining at least one first DMRS symbol offset value using method 2 or method 2 in step 201, after determining at least one time domain position based on the first usable symbol of the symbol resource and the at least one first DMRS symbol offset value, it is necessary to determine whether the determined at least one time domain position includes a time domain position beyond the symbol resource. Here, in one embodiment of the present disclosure, if a time domain position beyond the symbol resource exists, the time domain position beyond the symbol resource among the at least one time domain position is discarded to obtain the remaining time domain positions, and the remaining time domain positions are determined as first time domain positions of the DMRS. In another embodiment of the present disclosure, if no time domain positions beyond the symbol resource exist, the determined at least one time domain position is determined as the first time domain position of the DMRS.

[0111] For example, assume that the at least one time domain position determined based on the first usable symbol of the symbol resource and the at least one first DMRS symbol offset value may be symbol #1, symbol #5, and symbol #9, and the symbol resource is symbol #1 to symbol #8. In this case, since symbol #9 exceeds the time domain position of the symbol resource, symbol #9 is discarded, and only symbol #1 and symbol #5 are determined as the first time domain position of the DMRS.

[0112] Furthermore, in one embodiment of the present disclosure, when the UE determines the time domain location of the DMRS in the special slot, it can transmit the DMRS based on the time domain location of the DMRS.

[0113] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0114] FIG. 3 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 3, the frequency hopping method may include the following steps:

[0115] In step 301, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0116] In step 302, perform intra-slot frequency hopping in the uplink slot to determine available symbols in the special slot, and determine whether the number of available symbols in the symbol resource allocated by the base station is less than or equal to a first threshold; if the number of available symbols in the symbol resource allocated by the base station is less than or equal to the first threshold, perform step 303.

[0117] Here, in one embodiment of the present disclosure, the first threshold may specifically indicate the minimum number of symbols included in one hop when intra-slot frequency hopping is performed in a special slot, and exemplarily, the first threshold may be, for example, 3. Also, in one embodiment of the present disclosure, the first threshold may be indicated to the UE by the base station. In another embodiment of the present disclosure, the first threshold may be determined by the UE based on a protocol.

[0118] Here, in one embodiment of the present disclosure, if the number of available symbols in the symbol resource allocated by the base station is less than or equal to the first threshold, it means that the number of available symbols in the symbol resource currently allocated by the base station is insufficient to realize normal hopping, and in this case, step 303 can be performed.

[0119] In step 303, intra-slot frequency hopping is not performed in the special slot.

[0120] In step 304, at least one first DMRS symbol offset value is determined based on parameters set and / or indicated by the base station.

[0121] In step 305, determine a time domain location of the DMRS in the special slot based on a first available symbol of the symbol resources allocated by the base station and at least one first DMRS symbol offset value.

[0122] Here, for detailed explanations of steps 301 to 305, please refer to the above embodiments, and the explanations will be omitted in the embodiments of the present disclosure.

[0123] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0124] FIG. 4 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 4, the frequency hopping method may include the following steps:

[0125] In step 401, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0126] In step 402, perform intra-slot frequency hopping in the uplink slot to determine usable symbols in the special slot, and determine the time-domain location range of each hop of the special slot according to a method for determining the time-domain location range of each hop in the uplink slot (i.e., according to a method for determining the time-domain location range of each hop in the uplink slot) using the position of the first symbol among the symbol resources allocated by the base station as a starting position, and determine whether the number of usable symbols included in the determined time-domain location range of the first hop is smaller than a second threshold, and if the number of usable symbols included in the determined time-domain location range of the first hop is smaller than the second threshold, execute step 403, and if the number of usable symbols included in the determined time-domain location range of the first hop is equal to or greater than the second threshold, execute step 406.

[0127] For example, in one embodiment of the present disclosure, the second threshold may be, for example, 2. Also, in one embodiment of the present disclosure, the second threshold may be indicated to the UE by the base station. In another embodiment of the present disclosure, the second threshold may be determined by the UE based on a protocol.

[0128] In addition, in one embodiment of the present disclosure, if it is determined that the number of available symbols included in the time domain location range of the first hop is smaller than the second threshold, it indicates that the number of available symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is small, and uplink TBoMS transmission may not be possible at the currently determined first hop, so step 403 needs to be performed; if it is determined that the number of available symbols included in the time domain location range of the first hop is equal to or greater than the second threshold, it indicates that the number of available symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is large, and in this case, data can be transmitted successfully at the first hop, so step 406 can be performed.

[0129] In step 403, intra-slot frequency hopping is not performed in the special slot.

[0130] In step 404, at least one first DMRS symbol offset value is determined based on parameters set and / or indicated by the base station.

[0131] In step 405, determine a time domain location of the DMRS in the special slot based on a first available symbol of the symbol resources allocated by the base station and at least one first DMRS symbol offset value.

[0132] In step 406, intra-slot frequency hopping transmission is performed according to the time domain position range of each hop of the special slot determined with the position of the first symbol in the symbol resource as the starting position.

[0133] Here, for detailed explanations of steps 401 to 406, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0134] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0135] FIG. 5 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 5, the frequency hopping method may include the following steps:

[0136] In step 501, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0137] In step 502, perform intra-slot frequency hopping in the uplink slot to determine usable symbols in the special slot, and determine the time-domain location range of each hop of the special slot according to the method for determining the time-domain location range of each hop in the uplink slot, starting from the position of the first symbol among the symbol resources allocated by the base station; determine whether the difference between the number of usable symbols included in the determined time-domain location range of the second hop and the number of usable symbols included in the time-domain location range of the first hop is greater than a third threshold; if the difference between the number of usable symbols included in the determined time-domain location range of the second hop and the number of usable symbols included in the time-domain location range of the first hop is greater than the third threshold, execute step 503; if the difference between the number of usable symbols included in the determined time-domain location range of the second hop and the number of usable symbols included in the time-domain location range of the first hop is equal to or less than the third threshold, execute step 506.

[0138] In one embodiment of the present disclosure, the third threshold may be indicated to the UE by the base station, whereas in another embodiment of the present disclosure, the third threshold may be determined by the UE based on a protocol.

[0139] In addition, in one embodiment of the present disclosure, if it is determined that the difference between the number of usable symbols included in the time domain location range of the second hop and the number of usable symbols included in the time domain location range of the first hop is greater than the third threshold, it indicates that the number of usable symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is small, and uplink TBoMS transmission may not be possible at the currently determined first hop, so step 503 needs to be performed; if it is determined that the difference between the number of usable symbols included in the time domain location range of the second hop and the number of usable symbols included in the time domain location range of the first hop is equal to or smaller than the third threshold, it indicates that the number of usable symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is large, and in this case, data can be transmitted successfully at the first hop, so step 506 can be performed.

[0140] In step 503, intra-slot frequency hopping is not performed in the special slot.

[0141] In step 504, at least one first DMRS symbol offset value is determined based on parameters set and / or indicated by the base station.

[0142] In step 505, determine a time domain location of the DMRS in the special slot based on a first usable symbol of the symbol resources allocated by the base station and at least one first DMRS symbol offset value.

[0143] In step 506, intra-slot frequency hopping transmission is performed according to the time domain position range of each hop of the special slot determined with the position of the first symbol in the symbol resource as the starting position.

[0144] Here, for detailed explanations of steps 501 to 506, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0145] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0146] FIG. 6 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 6, the frequency hopping method may include the following steps:

[0147] In step 601, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0148] Here, for a detailed description of step 601, please refer to the description of the above embodiment, and the description will be omitted in the embodiment of the present disclosure.

[0149] In step 602, perform intra-slot frequency hopping in the uplink slot, determine available symbols in the special slot, and directly perform intra-slot frequency hopping on available symbols in the symbol resource.

[0150] Here, the method for determining the available symbols in the special slot can be referred to the above description, and the description will be omitted in the embodiment of the present disclosure.

[0151] In addition, in one embodiment of the present disclosure, a method for performing intra-slot frequency hopping with available symbols in a symbol resource may include determining a time-domain start position of a first hop in a special slot to be the position of the first available symbol in the symbol resource, and determining a time-domain end position of the first hop to be the position of the first available symbol in the assigned symbol resource + floor(number of available symbols in the symbol resource÷2)−1, where the floor function is a function that rounds down to the nearest integer; determining a time-domain start position of a second hop in the special slot to be the position of the first available symbol in the symbol resource + floor(number of available symbols in the symbol resource÷2), and determining a time-domain end position of the second hop to be the position of the first available symbol in the symbol resource + floor(number of available symbols in the symbol resource÷2)+number of available symbols in the symbol resource−floor(number of available symbols in the symbol resource÷2)−1.

[0152] For example, assuming that the symbol resources for data transmission in the special slot allocated by the base station are symbol #0 to symbol #10, where symbol #0 to symbol #2 are unusable symbols, it can be determined that the position of the first usable symbol in the symbol resource is symbol #3 and the number of usable symbols in the symbol resource is 8. Based on this, a method for performing frequency hopping in the symbol resources symbol #0 to symbol #10 may be as follows: The time domain start position of the first hop is determined to be symbol #3, and the time domain end position of the first hop is determined to be symbol #3 + floor(8÷2) - 1 = symbol #6. The time domain start position of the second hop is determined to be symbol #7, and the time domain end position of the second hop is determined to be symbol #3 + floor(8÷2) + 8 - floor(8÷2) - 1 = symbol #10. That is, the time domain position range of the first hop is from symbol #3 to symbol #6, and the time domain position range of the second hop is from symbol #7 to symbol #10.

[0153] In step 603, the time domain location of the DMRS for each hop is determined based on parameters set and / or indicated by the base station, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop.

[0154] Here, for detailed explanation of the parameters, please refer to the above explanation, and the explanation will be omitted in the embodiment of the present disclosure.

[0155] In one embodiment of the present disclosure, if the PUSCH mapping type in the parameters is type A, the time domain location of the DMRS for each hop is determined based on the parameters set and / or indicated by the base station, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop, in accordance with the mapping rule of type A. If the PUSCH mapping type in the parameters is type B, the time domain location of the DMRS for each hop is determined based on the parameters set and / or indicated by the base station, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop, in accordance with the mapping rule of type B.

[0156] Hereinafter, a method for determining the time domain location of a DMRS at each hop according to a type A mapping rule and a method for determining the time domain location of a DMRS at each hop according to a type B mapping rule will be described in detail.

[0157] Here, in one embodiment of the present disclosure, regardless of whether the mapping rule is type A or type B, to determine the time domain location of the DMRS at each hop, it is necessary to determine the time domain location of the DMRS at each hop by querying a second PUSCH DMRS location table using parameters, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop. Here, Table 5 is the second PUSCH DMRS location table provided by one embodiment of the present disclosure, and the UE can obtain the time domain location of the DMRS at each hop by querying Table 5 based on the parameters.

[0158] [Table 5]

[0159] Here, in one embodiment of the present disclosure, l in Table 5 dmay be the number of symbols included in the time domain location range of each hop. Also, when the UE needs to determine the time domain location of the DMRS of a hop, the number l included in the time domain range of the hop d determine the PUSCH mapping type, DMRS-Additional Position, and DMRS-type A Position (i.e., the value of l0 corresponding to PUSCH mapping Type A) in the parameters to determine at least one DMRS symbol offset value for the hop; then determine the sum of the symbol number of the starting symbol of the hop and each DMRS symbol offset value for the hop to obtain at least one sum; and determine the symbol whose symbol number corresponds to the sum as the time domain position of the DMRS for the hop.

[0160] For example, the time domain location of the DMRS of the second hop is determined, and the starting symbol of the second hop is symbol #7, and the number included in the time domain range of the second hop is 4 (i.e., l d = 4), the PUSCH mapping type is Type B, and DMRS-Additional Position = pos1. d =4, PUSCH mapping Type B, pos1, 2 nd By consulting Table 5 based on the hop, it can determine that the DMRS symbol offset value in the second hop is 0, and determine symbol#7+0=symbol#7 as the time domain position of the DMRS in the second hop.

[0161] Or, determine the time domain location of the DMRS of the second hop, and the starting symbol of the second hop is symbol #7, and the number included in the time domain range of the second hop is 4 (i.e., l d = 4), the PUSCH mapping type is Type A, DMRS-Additional Position = pos1, and DMRS-type A Position = 2 (i.e., l0 = 2). d=4, l0=2, PUSCH mapping Type A, pos1, 2 nd By consulting Table 5 based on the hop, it can determine that the DMRS symbol offset value in the second hop is 0, and determine symbol#7+0=symbol#7 as the time domain position of the DMRS in the second hop.

[0162] Based on this, in one embodiment of the present disclosure, a method for determining a starting symbol of each hop and determining a time domain position of a DMRS of each hop may include the following steps a to c. In step a, determine at least one second DMRS symbol offset value based on parameters set and / or indicated by the base station and the number of symbols included in the time domain location range of the second hop. In step b, determine the sum of the symbol number of the starting symbol of the second hop and each second DMRS symbol offset value to obtain at least one second sum value, and determine that the time domain position of the DMRS of the second hop is the symbol whose symbol number corresponds to the second sum value. In step c, determine the sum of the symbol number of the starting symbol of the first hop and each second DMRS symbol offset value to obtain at least one third sum value, and determine that the time domain position of the DMRS of the first hop is the symbol whose symbol number corresponds to the third sum value.

[0163] In addition, in another embodiment of the present disclosure, a method for determining a time domain position of a DMRS of each hop based on a starting symbol of each hop may include the following steps 1 to 4. Step 1 determines at least one second DMRS symbol offset value based on parameters set and / or indicated by the base station and the number of symbols included in the time domain location range of the second hop. In step 2, determine the sum of the symbol number of the starting symbol of the second hop and each second DMRS symbol offset value to obtain at least one second sum value, and determine that the time domain position of the DMRS of the second hop is the symbol whose symbol number corresponds to the second sum value. In step 3, determine at least one third DMRS symbol offset value based on parameters set and / or indicated by the base station and the number of symbols included in the time domain location range of the first hop. In step 4, determine the sum of the symbol number of the starting symbol of the first hop and each third DMRS symbol offset value to obtain at least one third sum value, and determine that the time domain position of the DMRS of the first hop is the symbol whose symbol number corresponds to the third sum value.

[0164] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0165] FIG. 7 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 7, the frequency hopping method may include the following steps:

[0166] In step 701, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0167] In step 702, perform intra-slot frequency hopping in the uplink slot to determine available symbols in the special slot, and determine whether the number of available symbols in the symbol resource allocated by the base station is greater than a first threshold; if the number of available symbols is greater than the first threshold, perform step 703.

[0168] Here, in one embodiment of the present disclosure, the first threshold may specifically indicate the minimum number of symbols included in one hop when intra-slot frequency hopping is performed in a special slot, and exemplarily, the first threshold may be, for example, 3. Also, in one embodiment of the present disclosure, the first threshold may be indicated to the UE by the base station. In another embodiment of the present disclosure, the first threshold may be determined by the UE based on a protocol.

[0169] Here, in one embodiment of the present disclosure, if the number of available symbols in the symbol resource allocated by the base station is greater than the first threshold, it means that the number of available symbols in the symbol resource currently allocated by the base station is sufficient to realize normal hopping, and in this case, step 703 can be performed.

[0170] In step 703, intra-slot frequency hopping is performed on available symbols within the symbol resource.

[0171] In step 704, the time domain location of the DMRS for each hop is determined based on parameters set and / or indicated by the base station, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop.

[0172] Here, for detailed explanations of steps 701 to 704, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0173] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0174] FIG. 8 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 8, this frequency hopping method may include the following steps:

[0175] In step 801, an instruction set by the base station to instruct intra-slot frequency hopping is obtained, parameters set and / or instructed by the base station are obtained, and symbol resources for data transmission in the special slot allocated by the base station are determined based on the parameters.

[0176] In step 802, perform intra-slot frequency hopping in the uplink slot to determine usable symbols in the special slot, and determine the time-domain location range of each hop of the special slot according to the method for determining the time-domain location range of each hop in the uplink slot, starting from the position of the first symbol among the symbol resources allocated by the base station, and determine whether the number of usable symbols included in the determined time-domain location range of the first hop is smaller than a second threshold. If the number of usable symbols included in the determined time-domain location range of the first hop is smaller than the second threshold, execute step 803; if the number of usable symbols included in the determined time-domain location range of the first hop is equal to or greater than the second threshold, execute step 805.

[0177] For example, in one embodiment of the present disclosure, the second threshold may be, for example, 2. Also, in one embodiment of the present disclosure, the second threshold may be indicated to the UE by the base station. In another embodiment of the present disclosure, the second threshold may be determined by the UE based on a protocol.

[0178] In addition, in one embodiment of the present disclosure, if it is determined that the number of available symbols included in the time domain location range of the first hop is smaller than the second threshold, it indicates that the number of available symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is small, and uplink TBoMS transmission may not be possible at the currently determined first hop, so step 803 needs to be performed; if it is determined that the number of available symbols included in the time domain location range of the first hop is equal to or greater than the second threshold, it indicates that the number of available symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is large, and in this case, data can be transmitted successfully at the first hop, so step 806 can be performed.

[0179] In step 803, intra-slot frequency hopping is performed on available symbols within the symbol resource.

[0180] In step 804, the time domain location of the DMRS for each hop is determined based on parameters set and / or indicated by the base station, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop.

[0181] In step 805, intra-slot frequency hopping transmission is performed according to the time domain position range of each hop of the special slot determined with the position of the first symbol in the symbol resource as the starting position.

[0182] Here, for detailed explanations of steps 801 to 805, please refer to the above embodiments, and explanations will be omitted in the embodiments of the present disclosure.

[0183] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0184] FIG. 9 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a UE. As shown in FIG. 9, this frequency hopping method may include the following steps:

[0185] In step 901, an instruction set by a base station to instruct intra-slot frequency hopping is obtained, and a symbol resource for data transmission in a special slot allocated by the base station is obtained.

[0186] In step 902, perform intra-slot frequency hopping in the uplink slot to determine usable symbols in the special slot, and determine the time-domain location range of each hop of the special slot according to the method for determining the time-domain location range of each hop in the uplink slot, starting from the position of the first symbol among the symbol resources allocated by the base station; determine whether the difference between the number of usable symbols included in the determined time-domain location range of the second hop and the number of usable symbols included in the time-domain location range of the first hop is greater than a third threshold; if the difference between the number of usable symbols included in the determined time-domain location range of the second hop and the number of usable symbols included in the time-domain location range of the first hop is greater than the third threshold, execute step 903; if the difference between the number of usable symbols included in the determined time-domain location range of the second hop and the number of usable symbols included in the time-domain location range of the first hop is equal to or less than the third threshold, execute step 904.

[0187] In one embodiment of the present disclosure, the third threshold may be indicated to the UE by the base station, whereas in another embodiment of the present disclosure, the third threshold may be determined by the UE based on a protocol.

[0188] In addition, in one embodiment of the present disclosure, if it is determined that the difference between the number of usable symbols included in the time domain location range of the second hop and the number of usable symbols included in the time domain location range of the first hop is greater than the third threshold, it indicates that the number of usable symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is small, and uplink TBoMS transmission may not be possible at the currently determined first hop, so step 903 needs to be performed; if it is determined that the difference between the number of usable symbols included in the time domain location range of the second hop and the number of usable symbols included in the time domain location range of the first hop is equal to or smaller than the third threshold, it indicates that the number of usable symbols included in the time domain location range of the first hop determined according to the method for determining the time domain location range of each hop in an uplink slot is large, and in this case, data can be transmitted successfully at the first hop, so step 906 can be performed.

[0189] In step 903, intra-slot frequency hopping is performed on available symbols within the symbol resource.

[0190] In step 904, the time domain location of the DMRS for each hop is determined based on parameters set and / or indicated by the base station, the number of symbols included in the time domain location range of each hop, and the starting symbol of each hop.

[0191] In step 905, intra-slot frequency hopping transmission is performed according to the time domain position range of each hop of the special slot determined with the position of the first symbol in the symbol resource as the starting position.

[0192] Here, for detailed explanations of steps 901 to 905, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0193] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the UE obtains a command set by the base station to instruct the UE to perform intra-slot frequency hopping, obtains symbol resources for data transmission in the special slot allocated by the base station, performs intra-slot frequency hopping in the uplink slot, determines available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resources, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot, which can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0194] FIG. 10 is a schematic flowchart of a frequency hopping method provided by an embodiment of the present disclosure, which is performed by a base station. As shown in FIG. 10, the frequency hopping method may include the following steps:

[0195] In step 1001, it is determined to perform intra-slot frequency hopping, an instruction is set to the UE to instruct it to perform intra-slot frequency hopping, parameters are determined, and symbol resources for data transmission in the special slot are determined based on the parameters.

[0196] In one embodiment of the present disclosure, the parameters may include at least one of a PUSCH mapping type, a symbol length for data transmission in a special slot, a starting symbol position for data transmission in a special slot, a DMRS-Additional Position, the number of DMRS ports, whether to start intra-slot frequency hopping, and a DMRS-type A Position. In one embodiment of the present disclosure, the PUSCH mapping type includes type A and type B.

[0197] In addition, in one embodiment of the present disclosure, the symbol resource for data transmission in the special slot allocated by the base station may be the symbol resource for uplink TBoMS transmission in the special slot. Also, in one embodiment of the present disclosure, the symbol resource for uplink TBoMS transmission may include a starting symbol position S and a symbol length L, and the symbol resource for uplink TBoMS transmission may specifically be symbols located at symbol positions [S, S+L-1] in the special slot.

[0198] For a specific method of determining symbol resources for data transmission in a special slot based on parameters, please refer to the above embodiments, and the description will be omitted in the embodiments of the present disclosure.

[0199] In step 1002, perform intra-slot frequency hopping in the uplink slot, determine available symbols in the special slot, and perform intra-slot frequency hopping on available symbols in the symbol resource, or do not perform intra-slot frequency hopping in the special slot.

[0200] Here, in one embodiment of the present disclosure, a method for determining usable symbols in a special slot may include determining unusable symbols from the special slot based on SFI dynamic instruction signaling and / or quasi-static slot format configuration signaling and / or other dynamic instruction signaling and / or other RRC configuration signaling transmitted from a base station, and determining that the usable symbols are symbols other than the unusable symbols in the special slot.

[0201] In one embodiment of the present disclosure, the unusable symbols may include at least one of guard symbols for downlink to uplink switching, downlink symbols for downlink transmission, symbols for transmitting SSBs, symbols assigned to CSSs, symbols occupied by CIs, and symbols for service transmissions with a higher priority than the current data transmission.

[0202] In one embodiment of the present disclosure, if a symbol in a special slot satisfies any one of the above conditions, the symbol is determined to be an unusable symbol.

[0203] In one embodiment of the present disclosure, the time domain resources allocated by the base station in step 1001 may include unusable symbols. In another embodiment of the present disclosure, the time domain resources allocated by the base station in step 1001 may not include unusable symbols.

[0204] In one embodiment of the present disclosure, when intra-slot frequency hopping is performed in an uplink slot, intra-slot frequency hopping may be performed only on available symbols in a symbol resource. In another embodiment of the present disclosure, when intra-slot frequency hopping is performed in an uplink slot, intra-slot frequency hopping may not be performed in a special slot.

[0205] In one embodiment of the present disclosure, if intra-slot frequency hopping is not performed in the special slot, the frequency domain location of the special slot is the same as the frequency domain location of any one hop of the uplink slot. For example, in one embodiment of the present disclosure, the frequency domain location of the special slot may be the same as the frequency domain location of the second hop of the uplink slot.

[0206] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot. If the base station determines to perform intra-slot frequency hopping, it performs intra-slot frequency hopping in the uplink slot, determines the available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resource, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0207] FIG. 11 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a base station. As shown in FIG. 11, the frequency hopping method may include the following steps:

[0208] In step 1101, it is determined to perform intra-slot frequency hopping, an instruction to instruct the UE to perform intra-slot frequency hopping is set, parameters are determined, and symbol resources for data transmission in the special slot are determined based on the parameters.

[0209] In step 1102, it is directly determined that intra-slot frequency hopping is performed in the uplink slot, and that intra-slot frequency hopping is not performed in the special slot.

[0210] In step 1103, determine at least one first DMRS symbol offset value based on the parameters.

[0211] In step 1104, determine a time domain location of the DMRS in the special slot based on the first usable symbol in the symbol resource and at least one first DMRS symbol offset value.

[0212] In one embodiment of the present disclosure, the method by which the base station determines the time domain location of the DMRS in the special slot is the same as the method by which the UE determines the time domain location of the DMRS in the special slot, and in one embodiment of the present disclosure, when the base station determines the time domain location of the DMRS in the special slot, the base station can receive and demodulate the DMRS based on the time domain location of the DMRS.

[0213] Further, for detailed explanations of steps 1101 to 1104, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0214] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot. If the base station determines to perform intra-slot frequency hopping, it performs intra-slot frequency hopping in the uplink slot, determines the available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resource, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0215] FIG. 12 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a base station. As shown in FIG. 12, this frequency hopping method may include the following steps:

[0216] In step 1201, it is determined to perform intra-slot frequency hopping, an instruction is set to the UE to instruct it to perform intra-slot frequency hopping, parameters are determined, and symbol resources for data transmission in the special slot are determined based on the parameters.

[0217] In step 1202, perform intra-slot frequency hopping in the uplink slot, determine the available symbols in the special slot, and determine whether the number of available symbols in the symbol resource is less than or equal to a first threshold. If the number of available symbols is less than or equal to the first threshold, execute step 1203.

[0218] In step 1203, intra-slot frequency hopping is not performed in the special slot.

[0219] In step 1204, determine at least one first DMRS symbol offset value based on the parameters.

[0220] In step 1205, determine a time domain location of the DMRS in the special slot based on the first usable symbol in the symbol resource and at least one first DMRS symbol offset value.

[0221] Here, for detailed explanations of steps 1201 to 1205, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0222] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot. If the base station determines to perform intra-slot frequency hopping, it performs intra-slot frequency hopping in the uplink slot, determines the available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resource, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0223] FIG. 13 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a base station. As shown in FIG. 13, this frequency hopping method may include the following steps:

[0224] In step 1301, it is determined to perform intra-slot frequency hopping, an instruction to instruct the UE to perform intra-slot frequency hopping is set, parameters are determined, and symbol resources for data transmission in the special slot are determined based on the parameters.

[0225] In step 1302, perform intra-slot frequency hopping in the uplink slot to determine usable symbols in the special slot, and determine the time-domain location range of each hop of the special slot according to the method for determining the time-domain location range of each hop in the uplink slot (i.e., according to the method for determining the time-domain location range of each hop in the uplink slot) starting from the position of the first symbol in the symbol resource, and determine whether the number of usable symbols included in the determined time-domain location range of the first hop is less than a second threshold. If the number of usable symbols included in the determined time-domain location range of the first hop is less than the second threshold, or if the number of usable symbols included in the determined time-domain location range of the first hop is greater than or equal to the second threshold, execute step 1306.

[0226] In step 1303, intra-slot frequency hopping is not performed in the special slot.

[0227] In step 1304, determine at least one first DMRS symbol offset value based on the parameters.

[0228] In step 1305, determine a time domain location of the DMRS in the special slot based on the first usable symbol in the symbol resource and at least one first DMRS symbol offset value.

[0229] In step 1306, intra-slot frequency hopping transmission is performed according to the time domain position range of each hop of the special slot determined with the position of the first symbol in the symbol resource as the starting position.

[0230] Here, for detailed explanations of steps 1301 to 1306, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0231] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot. If the base station determines to perform intra-slot frequency hopping, it performs intra-slot frequency hopping in the uplink slot, determines the available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resource, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0239] Here, for detailed explanations of steps 1401 to 1406, please refer to the above embodiments, and explanations will be omitted in the embodiments of the present disclosure.

[0240] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot. If the base station determines to perform intra-slot frequency hopping, it performs intra-slot frequency hopping in the uplink slot, determines the available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resource, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols.

[0243] In step 1502, perform intra-slot frequency hopping in the uplink slot, determine available symbols in the special slot, and directly perform intra-slot frequency hopping on available symbols in the symbol resource.

[0244] Here, in one embodiment of the present disclosure, the method by which the base station performs intra-slot frequency hopping on available symbols in the symbol resource is the same as the method by which the UE performs intra-slot frequency hopping on available symbols in the symbol resource.

[0245] In step 1503, determine the time-domain location of the DMRS for each hop based on the parameters, the number of symbols included in the time-domain location range of each hop, and the starting symbol of each hop.

[0246] Here, for detailed explanations of steps 1501 to 1503, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0247] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot.

Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols.

[0369] FIG. 30 is a schematic flowchart of another frequency hopping method provided by an embodiment of the present disclosure, which is performed by a base station. As shown in FIG. 30, this frequency hopping method may include the following steps:

[0370] In step 3001, it is determined to perform intra-slot frequency hopping, an instruction is set to the UE to instruct it to perform intra-slot frequency hopping, parameters are determined, and symbol resources for data transmission in the special slot are determined based on the parameters.

[0377] Here, for detailed explanations of steps 3001 to 3007, the above-mentioned embodiments can be referred to, and explanations thereof will be omitted in the embodiments of the present disclosure.

[0378] As described above, in the frequency hopping method provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot. If the base station determines to perform intra-slot frequency hopping, it performs intra-slot frequency hopping in the uplink slot, determines the available symbols in the special slot, and then performs intra-slot frequency hopping on the available symbols in the symbol resource, or does not perform intra-slot frequency hopping in the special slot. Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping needs to be performed in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This can avoid the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unusable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, intra-slot frequency hopping may be performed using available symbols in a special slot, and it is possible to ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, it is possible to avoid a situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

Therefore, in the embodiment of the present disclosure, when intra-slot frequency hopping is required in the uplink slot, intra-slot frequency hopping does not need to be performed in the special slot. This avoids the situation where "when intra-slot frequency hopping is performed in the special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop." This avoids resource waste, saves costs, and ensures frequency hopping stability. In addition, in the embodiments of the present disclosure, when intra-slot frequency hopping needs to be performed in an uplink slot, the intra-slot frequency hopping may be performed using available symbols in a special slot, which can ensure that each hop in the special slot contains a sufficient number of available symbols. Similarly, this can avoid the situation where "when intra-slot frequency hopping is performed in a special slot, the number of unavailable symbols in the first hop is large, making it impossible to perform uplink TBoMS transmission in the first hop," thereby avoiding resource waste, saving costs, and ensuring the stability of frequency hopping.

[0402] As described above, in the frequency hopping device provided by the embodiment of the present disclosure, the base station determines the symbol resource for data transmission in the special slot.
