[0073] The following abbreviations will be used in the embodiments of the present application: PUSCH: Physical Uplink Shared Channel,

[0074] See also Figure 1A , Figure 1A A flow chart of a method for determining a position is provided for an embodiment of the present application. Figure 1A As shown, the location determination method includes:

[0075] 101. If the PUSCH is transmitted in multiple transmission units, obtain transmission resource information of the PUSCH.

[0076] The transmission of PUSCH in multiple transmission units may be understood as data packets or information in PUSCH being transmitted in multiple transmission units.

[0077] The transmission resource information of the PUSCH may indicate the position of the PUSCH in the transmission unit, the number of the PUSCH in the transmission unit, etc.

[0078] In the embodiment of the present application, the transmission unit is taken as a time slot for example, and of course the transmission unit may also be a subframe, etc. When the transmission unit is a time slot, the transmission resource information may indicate the number of PUSCH symbols in the time slot, the position of the first symbol, the position of PUSCH in the time slot, etc. The first symbol may be understood as the starting symbol of PUSCH in the time slot.

[0079] The transmission unit is a time slot, and the transmission unit may include k time slots, and the k time slots may be represented as time slot n to time slot n+k-1, where k is a positive integer greater than or equal to 1, and n is a positive integer greater than or equal to 0. For example, if n is 0 and k is 1, the transmission unit includes 1 time slot, etc.

[0080] 102. Determine location information of a demodulation reference signal DMRS of the PUSCH according to the transmission resource information and resource information of the transmission unit.

[0081] The number of symbols of the PUSCH in the time slot, the position of the first symbol, the position of the PUSCH in the time slot, etc. can be determined according to the transmission resource information. The position information of the DMRS is determined according to the number of symbols in the time slot, the position of the first symbol, the position of the PUSCH in the time slot, etc. and the resource information of the transmission unit.

[0082] In a possible implementation, the transmission resource information includes the number m of symbols of the PUSCH, the resource information of the transmission unit includes the number M of symbols in a transmission unit, and a possible method for determining the position information of the demodulation reference signal DMRS of the PUSCH according to the transmission resource information and the resource information of the transmission unit includes:

[0083] A1. If m is less than M, determining, according to the transmission resource information, a first number of symbols of the PUSCH in the time slot n and a position of a first symbol of the PUSCH in the time slot n;

[0084] A2. Determine, according to the transmission resource information, a second number of symbols of the PUSCH in the time slot n+k-1, where the value of k is 2;

[0085] A3. Determine the position information of the DMRS in the time slot n according to the position of the first symbol of the PUSCH in the time slot n and the first number, and determine the position information of the DMRS in the time slot n+k-1 according to the second number of symbols of the PUSCH in the time slot n+k-1.

[0086] The PUSCH repetition type for transmitting the PUSCH can be obtained, which includes PUSCH repetition type A and PUSCH repetition type B. The location information of the DMRS is defined in PUSCH repetition type A and PUSCH repetition type B. PUSCH repetition type B supports repeated transmission within a time slot and repeated transmission within multiple time slots. As shown in Table 1, the following table shows a mapping relationship between the location information of the DMRS in PUSCH repetition type B and the transmission resources of the PUSCH.

[0087] Table 1 Mapping relationship between DMRS location information and PUSCH transmission resources

[0088]

[0089] Based on the above mapping table, the position information of the DMRS in the time slot n can be determined according to the position of the first symbol of the PUSCH in the time slot n and the first number, and the position information of the DMRS in the time slot n+k-1 can be determined according to the second number of symbols of the PUSCH in the time slot n+k-1.

[0090] In a specific example, if Figure 1B As shown, Figure 1B FIG. 2 shows a schematic diagram of the position of a PUSCH in a time slot. The transmission resource information includes: indicating that the length of the PUSCH channel to be transmitted is 13 symbols, pos2, and is mapping type B. Figure 1B As shown, PUSCH is transmitted from symbol 9 in slot n to symbol 7 in slot n+1. The transmission unit is slot, which contains 14 symbols. Through the above mapping table, it can be determined that the DMRS positions of mapping type B and length 13 specified by the protocol are respectively at the first symbol, symbol 5, and symbol 10 of the transmission.

[0091] Therefore, for a PUSCH channel length of 13 symbols, the first part is in time slot n and the second part is in time slot n+1. Regardless of the lengths of the parts in time slot n and time slot n+1, the length of the PUSCH transmission determines the position of the DMRS within the transmission duration. The position of the DMRS can be determined as: the position corresponding to symbol 9 in time slot n, and the position corresponding to symbol 0 and symbol 6 in time slot n+1.

[0092] In a possible embodiment, the position of the DMRS in the time slot n is the same as the position of the DMRS of the same length in a predefined time slot, and the position information of the DMRS in the time slot n+k-1 is the same as the position of the DMRS of the same length in a predefined time slot. The position of the DMRS in the predefined time slot can refer to the position defined in the aforementioned Table 1.

[0093] In another possible implementation, the transmission resource information includes the number m of symbols of the PUSCH, and the resource information of the transmission unit includes the number M of symbols in a transmission unit. Another method for determining the position information of the demodulation reference signal DMRS of the PUSCH according to the transmission resource information and the resource information of the transmission unit includes:

[0094] B1. If m is greater than M, the PUSCH is divided into x first parts and one second part, the number of symbols in the first part is M, and the number of symbols in the second part is mk*M;

[0095] B2. Determine first reference position information of the DMRS in the x first parts according to the position information of the time slot where the starting symbol of the x first parts is located;

[0096] B3. Determine, according to the predefined method, the second reference position information of the DMRS in the second part and the transmission length in the second part;

[0097] B4. Determine the location information of the DMRS according to the first reference location information, the second reference location information, the transmission length in the second part and the resource information of the transmission unit.

[0098] The first reference position information and the second reference position information may be determined with reference to the mapping relationship shown in Table 1 in the aforementioned embodiment, according to the channel length (number of symbols) of the PUSCH and the like.

[0099] The position corresponding to the start symbol of PUSCH in time slot n can be obtained, and the first reference position information can be mapped to the position information in time slot n to time slot n+k-1. According to the transmission length in the second part and the resource information of the transmission unit, the position corresponding to the second reference position of DMRS in the second part is determined to obtain the position of DMRS.

[0100] Optionally, the value of x is floor(m / M), where floor() is a round-down operation.

[0101] Optionally, the first reference position of the DMRS in the x first parts is the same as the DMRS position of the same M symbols under the same predefined DMRS configuration; the second reference position of the DMRS in the second part is the same as the DMRS position of the same length in a predefined time slot. The predefined DMRS configuration may be the configuration shown in Table 1.

[0102] The above-mentioned position information corresponds to the corresponding position, for example, the second reference position corresponds to the second reference position information.

[0103] like Figure 1C As shown, Figure 1C FIG. 2 shows another schematic diagram of the position of PUSCH during transmission in a time slot. Figure 1C As shown,

[0104] The transmission resource information includes: indicating that the length of the transmitted PUSCH channel is 19 symbols, pos2, which is mapping type B, and the transmission starts from symbol 9 in slot n and ends at symbol 14 in slot n+1. The transmission unit is a slot, and a slot contains 14 symbols. According to the protocol, the positions of the DMRS with mapping type B and a length of 5 symbols are respectively at the first symbol and the fifth symbol (the second reference position) of the transmission. The positions of the DMRS with mapping type B and a length of 14 are respectively at the first symbol and symbol 5 of the transmission, and the positions corresponding to symbol 10 (that is, the first reference position).

[0105] The PUSCH channel length is 19 symbols, which are divided into 2 parts. The first part is 14 (M) symbols starting from symbol 9 in time slot n (a first part is shown here), and the second part is 5 symbols starting from symbol 8 in time slot n+1. The position of DMRS within the transmission duration is determined by the length of the above PUSCH transmission (determined by the mapping table in Table 1 above). According to the configuration and the mapping table in Table 1 above, it is determined that the first reference position is mapped to the position corresponding to the starting symbol 9, 0 and symbol 6 in time slot n to time slot n+k-1. The position of DMRS in the second part corresponds to symbol 8 and symbol 13 in time slot n+1.

[0106] In a possible implementation manner, another possible method for determining the position information of the demodulation reference signal DMRS of the PUSCH according to the transmission resource information and the resource information of the transmission unit includes:

[0107] C1. Determine, according to the transmission resource information, a transmission length corresponding to the PUSCH in the time slot n to the time slot n+k-1;

[0108] C2. Determine the location information of the DMRS in each time slot from the time slot n to the time slot n+k-1 according to the transmission length corresponding to the PUSCH in the k time slots.

[0109] The transmission length can be understood as the number of PUSCH symbols in a time slot, etc.

[0110] According to the transmission length corresponding to the PUSCH in the k time slots, the position information of the DMRS in each time slot from the time slot n to the time slot n+k-1 is determined, and the position information of the DMRS in each time slot can be determined according to the mapping relationship shown in Table 1 in the aforementioned embodiment.

[0111] For example, in one example, Figure 1DAs shown, the transmission resource information includes: indicating that the length of the transmitted PUSCH channel is 19 symbols, pos2, and is mapping type B. The transmission starts from symbol 9 of slot n and ends at symbol 13 of slot n+1. And the transmission unit is slot, and the slot contains 14 symbols. From Table 1, it can be determined that the DMRS positions of mapping type B and length of 5 symbols are respectively at the first symbol and the fifth symbol of the transmission. The DMRS positions of mapping type B and length of 14 are respectively at the first symbol and symbol 5, and symbol 10 of the transmission.

[0112] The length of the PUSCH channel is 19 symbols, the first part is in time slot n, the second part is in time slot n+1, the length of the PUSCH part in time slot n is 5, and the position of the DMRS in this part can be determined from the configuration and Table 1 to be the position corresponding to the starting symbol 9 and symbol 13; the length of the PUSCH part in time slot n+1 is 14, and the position of the DMRS in this part can be determined from the configuration and Table 1 to be the position corresponding to the starting symbol 0, 5 and symbol 10.

[0113] Optionally, the position of the DMRS in each time slot from the time slot n to the time slot n+k-1 is the same as the position of a DMRS of the same length in a time slot with the same predefined DMRS configuration parameter.

[0114] In a possible implementation, the size of the transport block in the PUSCH may also be determined. Specifically, the size of the transport block in the PUSCH may be determined by the following method:

[0115] D1. If the PUSCH is repeatedly transmitted in the multiple transmission units, the number of DMRSs in the first transmission of the PUSCH is determined according to the position information of the DMRS in the time slot n and the position information of the DMRS in the time slot n+1;

[0116] D2. Determine the size of the transport block in the PUSCH according to the number of DMRSs in the PUSCH transmitted for the first time.

[0117] In this example, the location information of the DMRS may be determined by the method for determining the location information of the DMRS shown in the aforementioned embodiment, which will not be described in detail here.

[0118] The number of DMRSs may be determined according to the location information. Since the DMRSs correspond to the location information one-to-one, the number of DMRSs may be directly determined according to the number of locations.

[0119] like Figure 1E As shown, Figure 1EA schematic diagram of determining repeated transmission of PUSCH is shown in FIG. The length of PUSCH is 8 symbols, the first repeated transmission starts from symbol 10 in slot n, and the second repeated transmission starts from symbol 4 in slot n+1. There are 2 DMRS positions in the first repeated transmission, and there are 3 DMRS positions in the second repeated transmission. At this time, the calculation determines the size of the transport block according to the DMRS contained in the first transmission position.

[0120] In a possible implementation, the size of the transport block in the PUSCH may also be determined. Specifically, the size of the transport block in the PUSCH may be determined by the following method:

[0121] E1. If the PUSCH is repeatedly transmitted in multiple transmission units, and the PUSCH starts to be transmitted at the starting position of the transmission unit;

[0122] E2. determining the number of DMRS in the first transmission of the PUSCH according to the location information of the DMRS;

[0123] E3. Determine the size of the transport block in the PUSCH according to the number of DMRSs in the PUSCH transmitted for the first time.

[0124] In this example, the location information of the DMRS may be determined by the method for determining the location information of the DMRS shown in the aforementioned embodiment, which will not be described in detail here.

[0125] In a specific example, Figure 1F As shown, the length of PUSCH is 8 symbols, and the first repeated transmission starts from slot n symbol 0 (only one repeated transmission is shown in the figure). There are 3 DMRS positions in the first repeated transmission, and the size of the transport block in the PUSCH is determined according to the number of DMRS in the PUSCH in the first transmission (3).
