[0039] First, some nouns related to the embodiments of the present application are explained to facilitate the understanding of those skilled in the art.

[0040] 1, DMRS

[0041] DMRS is a reference signal used for channel estimation to demodulate the corresponding physical channel, such as PDSCH, PUSCH, Physical Downlink Control Channel (PDCCH), and Physical Uplink Control Channel (PUCCH). In PDSCH, the DMRS configuration type is indicated by the higher-layer parameter dmrs-Type, where type1 indicates DMRS configuration type 1 and type2 indicates DMRS configuration type 2.

[0042] 2. PTRS

[0043] PTRS is a reference signal used for phase noise tracking and compensation, and can be transmitted along with PUSCH and / or PDSCH. In PDSCH, the phaseTrackingRS field in DMRS-DownlinkConfig indicates whether PTRS is configured.

[0044] The time-domain density of PTRS is 1, 2, or 4, indicating that PTRS is configured for every 1, 2, or 4 symbols. The frequency-domain density of PTRS is 1 / n, which can be understood as PTRS being mapped on one subcarrier in every n resource blocks (RBs). That is, when each RB includes 12 subcarriers, the frequency-domain spacing of PTRS is 12*n subcarriers. The value of n can be, for example, 1, 2, 4, 8, 16, etc., and this embodiment does not limit this.

[0045] 3. Port

[0046] A port refers to an antenna port, specifically the port of an antenna module that transmits or receives signals. The antenna module involved in this application can be understood as a logical antenna unit, comprising at least one physical antenna unit. Each physical antenna unit includes devices such as a crystal oscillator. In practical applications, a port can correspond to a single physical antenna unit or an antenna array composed of multiple physical antenna units. In the embodiments of this application, a PTRS port refers to an antenna port used for transmitting PTRS, and a DMRS port refers to an antenna port used for transmitting DMRS.

[0047] The port index can be represented as 0, 1, 2..., or 1000, 1001, 1002..., or other representations. This application embodiment uses 0, 1, 2... as an example.

[0048] In the embodiment of the present application, the DMRS port associated with the PTRS port can be used to transmit the DMRS. The association relationship between the PTRS port and the DMRS port is used to determine the DMRS port associated with the PTRS port, so as to determine the transmission resource of the PTRS through the determined DMRS port.

[0049] Please refer to Figure 2 FIG. 1 is a flowchart of a port determination method provided by an embodiment of the present application. The method can include but is not limited to the following steps:

[0050] 201, the network device determines the DCI.

[0051] The DCI includes an association field, which is used to indicate the association relationship between the PTRS port and the DMRS port. For example, the association field can be a PTRS-DMRS association field.

[0052] In the scenario where the number of DMRS ports supported by the uplink (UL) is N≤4, in the case of configuring one PTRS port, for example, PTRS port 0, the association field is used to indicate the association relationship between the PTRS port 0 and the N DMRS ports. For example, N=4, the association field is used to indicate the association relationship between the PTRS port 0 and the 4 DMRS ports, which can be seen from Table 1 shown below.

[0053] Table 1

[0054] Values of the association field DMRS port 0 1st scheduled DMRS port 1 2nd scheduled DMRS port 2 3rd scheduled DMRS port 3 4th scheduled DMRS port

[0055] In Table 1, the number of bits of the association field is 2 bits, and different values of the 2 bits indicate that the PTRS port 0 is associated with different DMRS ports. The value of the association field is 0, which is used to indicate that the PTRS port 0 is associated with the first scheduled DMRS port; the value of the association field is 1, which is used to indicate that the PTRS port 0 is associated with the second scheduled DMRS port; the value of the association field is 2, which is used to indicate that the PTRS port 0 is associated with the third scheduled DMRS port; the value of the association field is 3, which is used to indicate that the PTRS port 0 is associated with the fourth scheduled DMRS port. The first scheduled DMRS port can be understood as the first port scheduled by the network device for transmitting the DMRS; the PTRS port 0 associated with the first scheduled DMRS port can be understood as that the first scheduled DMRS port and the PTRS port 0 share the same port.

[0056] In scenarios where the number of DMRS ports supported by UL is N≤4, when configuring two PTRS ports, such as PTRS port 0 and PTRS port 1, the association field is used to indicate the association relationship between PTRS port 0 and some of the N DMRS ports, and the association relationship between PTRS port 1 and some of the N DMRS ports. For example, when N=4, one bit of the association field is used to indicate the association relationship between PTRS port 0 and the two DMRS ports, and the other bit of the association field is used to indicate the association relationship between PTRS port 1 and the two DMRS ports, as shown in Table 2 below.

[0057] Table 2

[0058]

[0059]

[0060] In Table 2, the association field consists of 2 bits. MSB represents the most significant bit, and different MSB values ​​indicate that PTRS port 0 is associated with different DMRS ports. LSB represents the least significant bit, and different LSB values ​​indicate that PTRS port 1 is associated with different DMRS ports. These 2 bits can be represented as x1x0, where x1 represents the most significant bit and x0 represents the least significant bit. When x1 is 0, it means that PTRS port 0 is associated with the first DMRS port among those sharing PTRS port 0; when x1 is 1, it means that PTRS port 0 is associated with the second DMRS port among those sharing PTRS port 0. Similarly, when x0 is 0, it means that PTRS port 1 is associated with the first DMRS port among those sharing PTRS port 1; when x0 is 1, it means that PTRS port 1 is associated with the second DMRS port among those sharing PTRS port 1.

[0061] Among them, the first DMRS port in the DMRS ports that share PTRS port 0, for example, the DMRS ports that share PTRS port 0 include DMRS port 2 and DMRS port 3, and the first DMRS port of these two DMRS ports is DMRS port 2. Then, when the value of x1 is 0, it can be said that PTRS port 0 is associated with DMRS port 2.

[0062] The number N of DMRS ports supported by UL >In the scenario of 4, in the case of configuring 1 PTRS port, for example, PTRS port 0, in an implementation, the association field is used to indicate the association relationship between PTRS port 0 and N DMRS ports, for example, N = 8, the association field is used to indicate the association relationship between PTRS port 0 and 8 DMRS ports, for example, refer to Table 3 shown below.

[0063] Table 3

[0064] Values of the association field DMRS port 0 1st scheduled DMRS port 1 2nd scheduled DMRS port 2 3rd scheduled DMRS port 3 4th scheduled DMRS port 4 5th scheduled DMRS port 5 6th scheduled DMRS port 6 7th scheduled DMRS port 7 8th scheduled DMRS port

[0065] In Table 3, the number of bits of the association field is 3 bits, and different values of the 3 bits indicate that PTRS port 0 is associated with different DMRS ports. The value 0 of the association field is used to indicate that PTRS port 0 is associated with the first scheduled DMRS port; the value 1 of the association field is used to indicate that PTRS port 0 is associated with the second scheduled DMRS port; the value 2 of the association field is used to indicate that PTRS port 0 is associated with the third scheduled DMRS port; the value 3 of the association field is used to indicate that PTRS port 0 is associated with the fourth scheduled DMRS port; the value 4 of the association field is used to indicate that PTRS port 0 is associated with the fifth scheduled DMRS port; the value 5 of the association field is used to indicate that PTRS port 0 is associated with the sixth scheduled DMRS port; the value 6 of the association field is used to indicate that PTRS port 0 is associated with the seventh scheduled DMRS port; and the value 7 of the association field is used to indicate that PTRS port 0 is associated with the eighth scheduled DMRS port.

[0066] It should be noted that in Table 3, the DMRS ports indicated by each value are used for example, and do not constitute a limitation on the embodiments of the present application.

[0067] In another implementation, the association field is used to indicate the association relationship between PTRS port 0 and part of N DMRS ports, for example, N = 8, the association field is used to indicate the association relationship between PTRS port 0 and 4 DMRS ports, for example, refer to Table 4 shown below.

[0068] Table 4

[0069] Values of the association field DMRS port 0 1st scheduled DMRS port 1 5th scheduled DMRS port 2 2nd scheduled DMRS port 3 6th scheduled DMRS port

[0070] In Table 4, the bit number of the association field is 2 bits, and different values of the 2 bits indicate that PTRS port 0 is associated with different DMRS ports. The value 0 of the association field is used to indicate that PTRS port 0 is associated with the first scheduled DMRS port; the value 1 of the association field is used to indicate that PTRS port 0 is associated with the fifth scheduled DMRS port; the value 2 of the association field is used to indicate that PTRS port 0 is associated with the second scheduled DMRS port; and the value 3 of the association field is used to indicate that PTRS port 0 is associated with the sixth scheduled DMRS port.

[0071] It should be noted that in Table 4, the DMRS ports indicated by each value are used for example and do not constitute a limitation on the embodiments of the present application. For example, the value 0 of the association field is used to indicate that PTRS port 0 is associated with the first scheduled DMRS port; the value 1 of the association field is used to indicate that PTRS port 0 is associated with the third scheduled DMRS port; the value 2 of the association field is used to indicate that PTRS port 0 is associated with the fifth scheduled DMRS port; and the value 3 of the association field is used to indicate that PTRS port 0 is associated with the seventh scheduled DMRS port.

[0072] In the scenario of supporting N > 4 DMRS ports, in the case of configuring 2 PTRS ports, for example, PTRS port 0 and PTRS port 1, the association field is used to indicate the association relationship between PTRS port 0 and part of the N DMRS ports, and the association relationship between PTRS port 1 and part of the N DMRS ports.

[0073] In an implementation manner, for example, N = 8, 2 bits of the association field are used to indicate the association relationship between PTRS port 0 and 4 DMRS ports, and the remaining 2 bits of the association field are used to indicate the association relationship between PTRS port 1 and 4 DMRS ports, which can be referred to Table 5 shown below.

[0074] Table 5

[0075]

[0076] In Table 5, the number of bits of the association field is 4 bits, which can be expressed as x3x2x1x0, x3x2 represents MSB, and x1x0 represents LSB. When the value of x3x2 is 0, it indicates that PTRS port 0 is associated with the first DMRS port of the DMRS ports sharing PTRS port 0; when the value of x3x2 is 1, it indicates that PTRS port 0 is associated with the second DMRS port of the DMRS ports sharing PTRS port 0; when the value of x3x2 is 2, it indicates that PTRS port 0 is associated with the third DMRS port of the DMRS ports sharing PTRS port 0; when the value of x3x2 is 3, it indicates that PTRS port 0 is associated with the fourth DMRS port of the DMRS ports sharing PTRS port 0; when the value of x1x0 is 0, it indicates that PTRS port 1 is associated with the first DMRS port of the DMRS ports sharing PTRS port 1; when the value of x1x0 is 1, it indicates that PTRS port 1 is associated with the second DMRS port of the DMRS ports sharing PTRS port 1; when the value of x1x0 is 2, it indicates that PTRS port 1 is associated with the third DMRS port of the DMRS ports sharing PTRS port 1; when the value of x1x0 is 3, it indicates that PTRS port 1 is associated with the fourth DMRS port of the DMRS ports sharing PTRS port 1.

[0077] In an implementation, for example, N=8, the association field is used to indicate the association relationship between PTRS port 0 and 4 DMRS ports, and the association relationship between PTRS port 1 and 4 DMRS ports, which can be referred to Table 6 shown below.

[0078] Table 6

[0079]

[0080] In Table 6, the number of bits of the association field is 2 bits, which can be represented as x1x0. When the value of x1x0 is 0, it indicates that PTRS port 0 is associated with the 1st DMRS port of the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the 1st DMRS port of the DMRS ports sharing PTRS port 1; when the value of x1x0 is 1, it indicates that PTRS port 0 is associated with the 3rd DMRS port of the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the 3rd DMRS port of the DMRS ports sharing PTRS port 1; when the value of x1x0 is 2, it indicates that PTRS port 0 is associated with the 4th DMRS port of the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the 4th DMRS port of the DMRS ports sharing PTRS port 1; when the value of x1x0 is 3, it indicates that PTRS port 0 is associated with the 2nd DMRS port of the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the 2nd DMRS port of the DMRS ports sharing PTRS port 1.

[0081] The difference between Table 6 and Table 5 is as follows: (1) in Table 5, the value of one MSB is used to indicate the DMRS port associated with DMRS port 0, and the value of one LSB is used to indicate the DMRS port associated with DMRS port 1; in Table 6, one value of the association field is used to indicate the DMRS port associated with DMRS port 0 and the DMRS port associated with DMRS port 1 (it can be understood that the association field in Table 5 has high and low bits, while the association field in Table 6 does not distinguish between high and low bits); (2) Table 5 traverses all possible combinations, while Table 6 lists part of the possible combinations and does not traverse all possible combinations.

[0082] In an implementation manner, for example, N=8, 4 bits of the association field are used to indicate the association relationship between PTRS port 0 and 4 DMRS ports, and the association relationship between PTRS port 1 and 4 DMRS ports, which can be referred to Table 7 shown below.

[0083] Table 7

[0084]

[0087] The difference between Table 7 and Table 6 is that Table 6 lists some possible combinations, and Table 7 traverses all possible combinations.

[0088] It should be noted that in Table 5, Table 6 and Table 7, the DMRS ports indicated by each value are used for example, and do not constitute a limitation on the embodiments of the present application.

[0089] In the scenario of supporting N > 4 DMRS ports in UL, the network device determines the number of bits of the association field in DCI according to the configured number of PTRS ports.

[0090] In the case of configuring the first PTRS port, that is, in the case of configuring one PTRS port, for example, PTRS port 0, in an implementation manner, the number of bits of the association field is related to N, for example, can be represents rounding up. For example, N=8, the number of bits of the association field is 3 bits; N=16, the number of bits of the association field is 4 bits. In another implementation, the number of bits of the association field is irrelevant to N, and by default, it is 2 bits, which can indicate the association relationship between PTRS port 0 and 4 DMRS ports, which are any four of the N DMRS ports, and the specific four can be specified by the protocol.

[0091] In the case of configuring the second PTRS port and the third PTRS port, i.e., in the case of configuring 2 PTRS ports, such as PTRS port 0 and PTRS port 1, in an implementation, the number of bits of the association field is relevant to N, which can be, for example, or represents rounding up. For example, N=8, the number of bits of the association field is 4 bits, 2 bits are used to indicate the DMRS port associated with PTRS port 0 (the 2 bits can be the high 2 bits, or any 2 bits selected), and the other 2 bits are used to indicate the DMRS port associated with PTRS port 1. For another example, N=16, the number of bits of the association field is 6 bits, 3 bits are used to indicate the DMRS port associated with PTRS port 0 (the 3 bits can be the high 3 bits, or any 3 bits selected), and the other 3 bits are used to indicate the DMRS port associated with PTRS port 1. In another implementation, the number of bits of the association field is irrelevant to N, and by default, it is 2 bits, and the value of the 2 bits indicates the DMRS port associated with PTRS port 0, and the DMRS port associated with PTRS port 1.

[0092] The network device further determines the value of the association field to indicate the DMRS port associated with the PTRS port in the case of determining the number of bits of the association field in the DCI.

[0093] 202, the network device sends the DCI to the terminal device. Correspondingly, the terminal device receives the DCI from the network device.

[0094] The network device sends the DCI to the terminal device in the case of determining the DCI, so that the terminal device determines the DMRS port associated with the PTRS port according to the association field in the DCI.

[0095] 203a, in the case of configuring the first PTRS port, the DMRS port associated with the first PTRS port is determined according to the association field.

[0096] 203b, in the case of configuring the second PTRS port and the third PTRS port, the DMRS port associated with the second PTRS port and the DMRS port associated with the third PTRS port are determined according to the association field.

[0097] The above Tables 1 to 6 can be predefined by a protocol and known by both the network device and the terminal device. In a case where the terminal device receives the DCI, the terminal device determines the DMRS port associated with the PTRS port according to the configured number of PTRS ports, and the number of bits and the value of the association field in the DCI. The terminal device can learn the configured number of PTRS ports as one or two through radio resource control (RRC) signaling.

[0098] In a case where one PTRS port is configured, the terminal device performs step 203a; in a case where two PTRS ports are configured, the terminal device performs step 203b.

[0099] In a case where the first PTRS port is configured, i.e., in a case where one PTRS port is configured, for example, PTRS port 0, the terminal device determines the DMRS port associated with the PTRS port 0 according to the number of bits and the value of the association field. For example, the number of bits of the association field is 3 bits, and the value is 7, in combination with Table 3, it can be determined that the PTRS port 0 is associated with the 8th scheduled DMRS port. For another example, the number of bits of the association field is 2 bits, and the value is 3, in combination with Table 4, it can be determined that the PTRS port 0 is associated with the 6th scheduled DMRS port.

[0100] In a case where the second PTRS port and the third PTRS port are configured, i.e., in a case where two PTRS ports are configured, for example, PTRS port 0 and PTRS port 1, the terminal device determines the DMRS port associated with the PTRS port 0 and the DMRS port associated with the PTRS port 1 according to the number of bits and the value of the association field. For example, the number of bits of the association field is 4 bits, the value of the high bit is 2, and the value of the low bit is 2, in combination with Table 5, it can be determined that the PTRS port 0 is associated with the 3rd DMRS port in the DMRS ports sharing the PTRS port 0, and the PTRS port 1 is associated with the 3rd DMRS port in the DMRS ports sharing the PTRS port 1. For another example, the number of bits of the association field is 2 bits, and the value is 3, in combination with Table 6, it can be determined that the PTRS port 0 is associated with the 2nd DMRS port in the DMRS ports sharing the PTRS port 0, and the PTRS port 1 is associated with the 2nd DMRS port in the DMRS ports sharing the PTRS port 1.

[0101] In Figure 2 In the embodiment shown in the figure, the network device indicates the association relationship between the PTRS port and the DMRS port through the association field in the DCI, so that the terminal device can quickly and accurately determine the DMRS port associated with the PTRS port.
