First, some nouns involved in the embodiments of the present application are explained to facilitate the understanding of those skilled in the art.

1. DMRS

DMRS is a reference signal used for channel estimation to demodulate corresponding physical channels, such as PDSCH, PUSCH, physical downlink control channel (physical downlink control channel, PDCCH), physical uplink control channel (physical uplink control channel, PUCCH), etc. . In the PDSCH, the configuration type of the DMRS is indicated by the high layer parameter dmrs-Type, type1 indicates DMRS configuration type 1, and type2 indicates DMRS configuration type 2.

2. PTRS

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 field phaseTrackingRS in DMRS-DownlinkConfig is used to indicate whether PTRS is configured.

The time domain density of the PTRS is 1, 2 or 4, indicating that the PTRS is configured every 1, 2 or 4 symbols. The frequency domain density of PTRS is 1/n, which can be understood as PTRS is mapped on 1 subcarrier in every n resource blocks (resource block, RB), that is, when each RB includes 12 subcarriers, the frequency domain interval of PTRS is 12 *n subcarriers. Wherein, the value of n may be, for example, 1, 2, 4, 8, 16, etc., which is not limited in this embodiment of the present application.

3. Port

The port refers to an antenna port, and represents a port of an antenna module that sends or receives a signal. The antenna module involved in this application can be understood as a logical antenna unit, which includes at least one physical antenna unit, and each physical antenna unit includes devices such as crystal oscillators, that is, in practical applications, a port can correspond to a physical antenna unit , may also correspond to an antenna array composed of multiple physical antenna elements. In the embodiment of the present application, the PTRS port refers to an antenna port used for transmitting PTRS, and the DMRS port refers to an antenna port used for transmitting DMRS.

The representation of the port index can be 0, 1, 2..., 1000, 1001, 1002..., or other representations. In the embodiment of the present application, 0, 1, 2... are taken as examples.

In this embodiment of the present application, the DMRS port associated with the PTRS port may be used to transmit 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.

Please refer to Figure 2, which is a schematic flow chart of a port determination method provided in the embodiment of the present application, which may include but not limited to the following steps:

201. The network device determines DCI.

Wherein, the DCI includes an association field, and the association field is used to indicate the association relationship between the PTRS port and the DMRS port. For example, the association field may be the PTRS-DMRS association field.

In the scenario where the number of DMRS ports supported by the uplink (uplink, UL) is N≤4, in the case of configuring one PTRS port, such as PTRS port 0, the association field is used to indicate the relationship between PTRS port 0 and N DRMS ports relationship. For example, N=4, the association field is used to indicate the association relationship between PTRS port 0 and 4 DMRS ports, as shown in Table 1 below.

Table 1

关联域的取值The value of the associated field	DMRS端口DMRS port

11	第2个被调度的DMRS端口The second scheduled DMRS port
22	第3个被调度的DMRS端口The third scheduled DMRS port
33	第4个被调度的DMRS端口The fourth scheduled DMRS port

In Table 1, the number of bits in the association field is 2 bits, and different values of these 2 bits indicate that PTRS port 0 is associated with different DMRS ports. The value of the association field is 0, which is used to indicate that 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 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 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 PTRS port 0 is associated with the fourth scheduled DMRS port. Among them, the first scheduled DMRS port can be understood as the first port scheduled by the network device for transmitting DMRS; PTRS port 0 is associated with the first scheduled DMRS port, which can be understood as the first scheduled port The scheduled DMRS port shares the same port with PTRS port 0.

In the scenario where the number of DMRS ports supported by UL is N≤4, in the case of configuring 2 PTRS ports, such as PTRS port 0 and PTRS port 1, the association field is used to indicate PTRS port 0 and part of the DMRS ports in the N DRMS ports The association relationship between ports, and the association relationship between PTRS port 1 and some DMRS ports in the N DRMS ports. For example, N=4, one bit of the association field is used to indicate the association relationship between PTRS port 0 and 2 DMRS ports, and the other bit of the association field is used to indicate the association relationship between PTRS port 1 and 2 DRMS ports , as shown in Table 2 below.

Table 2

In Table 2, the number of bits in the association field is 2 bits, MSB represents the most significant bit, and different values of the MSB indicate that PTRS port 0 is associated with different DMRS ports; LSB represents the least significant bit (least significant bit), and the value of the LSB Different values indicate that PTRS port 1 is associated with different DMRS ports. These 2 bits can be represented as x1x0, where x1 represents the high bit and x0 represents the low bit. When the value of x1 is 0, it means that PTRS port 0 is associated with the first DMRS port among the DMRS ports sharing PTRS port 0; when the value of x1 is 1, it means that PTRS port 0 is associated with the DMRS port sharing PTRS port 0 The second DMRS port in the PTRS port; when the value of x0 is 0, it means that PTRS port 1 is associated with the first DMRS port among the DMRS ports sharing PTRS port 1; when the value of x0 is 1, it means that PTRS port 1 is associated The second DMRS port among the DMRS ports sharing PTRS port 1.

Wherein, the first DMRS port among the DMRS ports sharing PTRS port 0, for example, the DMRS port sharing PTRS port 0 includes DMRS port 2 and DMRS port 3, and the first DMRS port among these two DMRS ports is a DMRS port 2, then when the value of x1 is 0, it may indicate that PTRS port 0 is associated with DMRS port 2.

In the scenario where the number of DMRS ports supported by UL is N>4, in the case of configuring one PTRS port, for example, PTRS port 0, in one implementation, the association field is used to indicate the relationship between PTRS port 0 and N DRMS ports For example, N=8, the association field is used to indicate the association relationship between PTRS port 0 and 8 DMRS ports, as shown in Table 3 below.

table 3

关联域的取值The value of the associated field	DMRS端口DMRS port

In Table 3, the number of bits in the association field is 3 bits, and different values of these 3 bits indicate that PTRS port 0 is associated with different DMRS ports. The value of the association field is 0, which is used to indicate that 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 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 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 PTRS port 0 is associated with the fourth scheduled DMRS port; The value of the association field is 4, which is used to indicate that PTRS port 0 is associated with the fifth scheduled DMRS port; the value of the association field is 5, which is used to indicate that PTRS port 0 is associated with the sixth scheduled DMRS port; The value of the association field is 6, which is used to indicate that PTRS port 0 is associated with the seventh scheduled DMRS port; the value of the association field is 7, which is used to indicate that PTRS port 0 is associated with the eighth scheduled DMRS port.

It should be noted that, in Table 3, the DMRS port indicated by each value is used as an example, and does not constitute a limitation to the embodiment of the present application.

In another implementation, the association field is used to indicate the association relationship between PTRS port 0 and some DMRS ports in the N DRMS ports, for example, N=8, and the association field is used to indicate the relationship between PTRS port 0 and 4 DMRS ports. The relationship between them can be seen in Table 4 below.

33	第6个被调度的DMRS端口The sixth scheduled DMRS port

In Table 4, the number of bits in the association field is 2 bits, and different values of these 2 bits indicate that PTRS port 0 is associated with different DMRS ports. The value of the association field is 0, which is used to indicate that 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 PTRS port 0 is associated with the fifth scheduled DMRS port; The value of the association field is 2, which is used to indicate that PTRS port 0 is associated with the second scheduled DMRS port; the value of the association field is 3, which is used to indicate that PTRS port 0 is associated with the sixth scheduled DMRS port.

It should be noted that, in Table 4, the DMRS port indicated by each value is used as an example, and does not constitute a limitation to the embodiment of the present application. For example, the value of the association field is 0, which is used to indicate that 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 PTRS port 0 is associated with the third scheduled DMRS port port; the value of the association field is 2, which is used to indicate that PTRS port 0 is associated with the fifth scheduled DMRS port; the value of the association field is 3, which is used to indicate that PTRS port 0 is associated with the seventh scheduled DMRS port port.

In the scenario where the number of DMRS ports supported by UL is N>4, in the case of configuring 2 PTRS ports, such as PTRS port 0 and PTRS port 1, the association field is used to indicate PTRS port 0 and part of the DMRS ports in the N DRMS ports The association relationship between ports, and the association relationship between PTRS port 1 and some DMRS ports in the N DRMS ports.

In one implementation, 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 PTRS port 1 and 4 DRMS ports For the association relationship between ports, see Table 5 below.

table 5

In Table 5, the number of bits in the association field is 4 bits, which can be represented as x3x2x1x0, where x3x2 represents the MSB, and x1x0 represents the LSB. When the value of x3x2 is 0, it means that PTRS port 0 is associated with the first DMRS port among the DMRS ports sharing PTRS port 0; when the value of x3x2 is 1, it means that PTRS port 0 is associated with the DMRS port sharing PTRS port 0 The second DMRS port in ; when the value of x3x2 is 2, it means that PTRS port 0 is associated with the third DMRS port among the DMRS ports sharing PTRS port 0; when the value of x3x2 is 3, it means that PTRS port 0 is associated It is the fourth DMRS port among the DMRS ports sharing PTRS port 0; when the value of x1x0 is 0, it means that PTRS port 1 is associated with the first DMRS port among the DMRS ports sharing PTRS port 1; the value of x1x0 is When 1, it means that PTRS port 1 is associated with the second DMRS port among the DMRS ports sharing PTRS port 1; when the value of x1x0 is 2, it means that PTRS port 1 is associated with the third DMRS port among the DMRS ports sharing PTRS port 1 DMRS port; when the value of x1x0 is 3, it means that PTRS port 1 is associated with the fourth DMRS port among the DMRS ports sharing PTRS port 1.

In one 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 DRMS ports, as shown in the following table 6.

Table 6

In Table 6, the number of bits in the association field is 2 bits, which can be expressed as x1x0. When the value of x1x0 is 0, it means that PTRS port 0 is associated with the first DMRS port among the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the first DMRS port among the DMRS ports sharing PTRS port 1; x1x0 When the value of is 1, it means that PTRS port 0 is associated with the third DMRS port among the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the third DMRS port among the DMRS ports sharing PTRS port 1; x1x0 When the value is 2, it means that PTRS port 0 is associated with the fourth DMRS port among the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the fourth DMRS port among the DMRS ports sharing PTRS port 1; When the value is 3, it means that PTRS port 0 is associated with the second DMRS port among the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with the second DMRS port among the DMRS ports sharing PTRS port 1.

The difference between Table 6 and Table 5 is: (1) In Table 5, a value of MSB is used to indicate the DMRS port associated with DMRS port 0, and a value of LSB is used to indicate the DMRS port associated with DMRS port 1; Table 6 , a value of the association domain 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 domain in Table 5 has high and low bits, and the DMRS port in Table 6 (2) Table 5 traverses all possible combinations, while Table 6 lists some possible combinations, but does not traverse all possible combinations.

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

It should be noted that, in Table 5, Table 6, and Table 7, the DMRS ports indicated by the respective values are used as examples, and do not constitute limitations to the embodiments of the present application.

In the scenario where the number of DMRS ports supported by the UL is N>4, the network device determines the number of bits in the association field in the DCI according to the configured number of PTRS ports.

In the case of configuring the first PTRS port, that is, in the case of configuring a PTRS port, such as PTRS port 0, in one implementation, the number of bits in the association field is related to N, for example, it may be

Indicates rounding up. For example, N=8, the number of bits in the association field is 3 bits; N=16, the number of bits in the association field is 4 bits. In another implementation, the number of bits in the association field has nothing to do with N, and the default is 2 bits. These 2 bits can indicate the association relationship between PTRS port 0 and 4 DMRS ports. These 4 DMRS ports are N DMRS ports. Any four of the ports, which four can be specified by the protocol.

In the case of configuring the second PTRS port and the third PTRS port, that is, in the case of configuring two PTRS ports, such as PTRS port 0 and PTRS port 1, in one implementation, the number of bits in the association field is related to N, For example it could be

or

Indicates rounding up. For example, N=8, the number of bits in the association field is 4 bits, and 2 bits are used to indicate the DMRS port associated with PTRS port 0 (these 2 bits can be high-order 2 bits, or 2 bits selected arbitrarily), and the other 2 bits Used to indicate the DMRS port associated with PTRS port 1. For another example, N=16, the number of bits in the association field is 6 bits, and 3 bits are used to indicate the DMRS port associated with PTRS port 0 (these 3 bits can be high-order 3 bits, or 3 bits selected arbitrarily), and the other 3 bits Bit used to indicate the DMRS port to which PTRS port 1 is associated. In another implementation manner, the number of bits in the association field has nothing to do with N, and is 2 bits by default. The value of these 2 bits indicates the DMRS port associated with PTRS port 0 and the DMRS port associated with PTRS port 1.

In the case of determining the bit number of the association field in the DCI, the network device further determines the value of the association field to indicate the DMRS port associated with the PTRS port.

202. The network device sends DCI to the terminal device. Correspondingly, the terminal device receives the DCI from the network device.

When the DCI is determined, the network device sends the DCI to the terminal device, so that the terminal device determines the DMRS port associated with the PTRS port according to the association field in the DCI.

203a. In the case of configuring the first PTRS port, determine the DMRS port associated with the first PTRS port according to the association field.

203b. In the case of configuring the second PTRS port and the third PTRS port, determine the DMRS port associated with the second PTRS port and the DMRS port associated with the third PTRS port according to the association field.

The above Tables 1 to 6 may be predefined by the protocol, known by both the network device and the terminal device. When the terminal device receives the DCI, it determines the DMRS port associated with the PTRS port according to the configured number of PTRS ports and the bit number and value of the association field in the DCI. The terminal device can learn that the number of configured PTRS ports is one or two through radio resource control (radio resource control, RRC) signaling.

In the case of configuring one PTRS port, the terminal device performs step 203a; in the case of configuring two PTRS ports, the terminal device performs step 203b.

In the case of configuring the first PTRS port, that is, configuring one PTRS port, for example, PTRS port 0, the terminal device determines the DMRS port associated with PTRS port 0 according to the number and value of bits in the association field. For example, the number of bits in the association field is 3 bits, and the value is 7. In combination with Table 3, it can be determined that PTRS port 0 is associated with the eighth scheduled DMRS port. For another example, the number of bits in the association field is 2 bits, and the value is 3. In combination with Table 4, it can be determined that PTRS port 0 is associated with the sixth scheduled DMRS port.

In the case where the second PTRS port and the third PTRS port are configured, that is, when two PTRS ports are configured, for example, PTRS port 0 and PTRS port 1, the terminal device determines the PTRS port 0 according to the number and value of the bits in the associated field The associated DMRS port and the DMRS port associated with PTRS port 1. For example, the number of bits in 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 PTRS port 0 is associated with the third DMRS port among the DMRS ports sharing PTRS port 0. port, PTRS port 1 is associated with the third DMRS port among the DMRS ports sharing PTRS port 1. For another example, the number of bits in the association domain is 2 bits, and the value is 3. In combination with Table 6, it can be determined that PTRS port 0 is associated with the second DMRS port among the DMRS ports sharing PTRS port 0, and PTRS port 1 is associated with sharing PTRS port 1. The second DMRS port in the DMRS port.

In the embodiment shown in FIG. 2 , 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.
