In some scenarios, a terminal may support uplink transmission of up to 4 antenna ports. To support uplink transmission of FR2, the terminal may be configured with 1 to 2 phase tracking reference signal (PTRS) port(s), and each PTRS port is associated with a different transport layer or a different demodulation reference signal (DMRS), and a PTRS may be configured for phase tracking and adjustment of an associated transport layer or DMRS, thereby ensuring performance of a channel estimation of DMRS and data demodulation. For a full coherent codebook, all transport layers/DMRS ports are associated with a same PTRS port (in this case, the network device will only be configured with one PTRS port). For the case of configuring a partial-coherent codebook and a non-coherent codebook, a number of the PTRS ports actually transmitted depends on a number of transport layers and an indication of the transmitted precoding matrix indicator (TPMI). A physical uplink shared channel (PUSCH) antenna ports 1000 and 1002, as well as a DMRS (transport layer) transmitted on these two ports are associated with PTRS port 0 (that is, a phase estimation result on the PTRS port may be used for the PUSCH and the DMRS transmitted on these two antenna ports). The PUSCH antenna ports 1001 and 1003 and a DMRS (transport layer) transmitted on these two ports are associated with PTRS port 1. If there are a plurality of DMRS ports transmitted on an antenna port, which DMRS port of the plurality of DMRS ports being actually associated with a corresponding PTRS port needs to be determined according to indication information in downlink control information (DCI). The PTRS port and an associated DMRS port use a same sequence, frequency domain resource and precoding matrix.
In addition, since a PTRS port may be associated with a plurality of transport layers, in order to ensure that the power on different orthogonal frequency-division multiplexing (OFDM) symbols is consistent, power of PTRS needs to be adjusted according to the number of configured transport layers. Specifically, based on the difference of the number of transport layers, a coherent configuration of the codebook and the transmission scheme (based on codebook transmission or non-codebook transmission), power boosting of a PTRS relative to an associated DMRS port may be obtained from Table 1. The specific power boosting scheme to be adopted is configured by the network device. Herein, a power boosting value is a boosting value of the transmit power of one PTRS port relative to a DMRS port or a transport layer associated with the PTRS port. Qp is a number of PTRS ports currently configured (1 or 2), coherent configuration of the codebook (full coherent codebook/partial-coherent codebook/non-coherent) and the transmission scheme configuration (codebook based or non-codebook based) are obtained by a high-level signaling.
In related technologies, uplink transmission supports up to 4 PUSCH antenna ports. At the same time, in FR2, the network device may be configured at most 2 PTRS ports to be associated with the PUSCH antenna port.
In some scenarios, some advanced terminals may be configured with more transmission links or radio frequency channels, and at this time, the advanced terminals may support more PUSCH antenna ports, e.g., 8 PUSCH antenna ports, to further improve uplink transmission performance. In this case, how to transmit the PTRS to support more PUSCH antenna ports and thus improve the uplink transmission performance is an urgent problem that needs to be solved.

In the following, in combination with Embodiment 1, a method for determining the number N of PTRS ports used for the uplink transmission of X antenna ports is described.
Embodiment 1: the determination of the number N of PTRS ports used for the uplink transmission of X antenna ports.
Embodiment 1-1: the terminal device determines, based on the number K of antenna port groups contained in the X antenna ports, the number N of the PTRS ports.
In some embodiments, the number N of the PTRS ports is less than or equal to K.
In some embodiments, the terminal device may determine the number N of the PTRS ports based on the number K of antenna port groups contained in the X antenna ports and the coherent configuration of the codebook.
Optionally, the coherent configuration of the codebook may include a full coherent codebook, a partial-coherent codebook, and a non-coherent codebook.
In an implementation, the terminal device may report the number of antenna port groups to the network device. For example, the number of the antenna port groups may be carried in UE capability information to be reported to the network device, and the number of PTRS ports may be configured by the network device. In a case where the non-coherent codebook is configured or the partial-coherent codebook is configured, the network device should ensure that the number of the antenna port groups and the number of PTRS ports are equal when the number of PTRS ports is configured, that is, a number of antenna port groups currently configured by the terminal device is the same as a number of PTRS ports configured by the network device. However, there is no such requirement upon configuring the full coherent codebook.
In another implementation, the terminal device may report the number of antenna port groups to the network device. For example, the number of the antenna port groups may be carried in UE capability information to be reported to the network device. In a case where the non-coherent codebook is configured or the partial-coherent codebook is configured, the terminal device directly determines the number N of the PTRS ports based on the number of antenna port groups reported in the UE capability information, while there is no need for the network device to configure the number of PTRS ports. When the full coherent codebook is configured, it is necessary to assume that N is fixed to 1, regardless of UE capability.
In some embodiments, in a case where the partial-coherent codebook is configured, the number N of the PTRS ports may be configured by the network device.
For example, in a case where X=8 and the network device configures a non-coherent codebook for the terminal device, N=K=8.
For another example, in a case where X=8 and the network device configures a partial-coherent codebook for the terminal device, if K=4, then N may be one of 1, 2, or 4, and the specific value of N may be configured by the network device; if K=2, then N may be one of 1 or 2, and the specific value of N may be configured by the network device.
For another example, in a case where X=8, and the network device configures a full coherent codebook for the terminal device, the number N of the PTRS ports is 1, which does not require to be configured by the network device.
In some embodiments, in a case where the non-coherent codebook is configured, the number N of the PTRS ports may be configured by the network device.
For example, in a case where X=8, and the network device configures a non-coherent codebook for the terminal device, then K=8, and the value of N may be one of 1, 2, 4, or 8, and the specific value of N may be configured by the network device.
For another example, in a case where X=8 and the network device configures a partial-coherent codebook for the terminal device, N=K=4 or N=K=2.
Optionally, in the embodiments of the present disclosure, the codebook being a full coherent codebook, a partial-coherent codebook, or a non-coherent codebook (i.e., a coherent configuration of the codebook) is configured by the network device through a high-layer signaling. For example, the high-layer signaling may include but is not limited to a radio resource control (RRC) signaling.
In an implementation, the number K of antenna port groups included in the X antenna ports is preconfigured for the terminal device by the network device. For example, the network device notifies the terminal device of the number K in advance through the high-layer signaling. That is, the network device and the terminal device have the same understanding of the number K of the antenna port groups. Furthermore, in a case where K takes different values, the antenna ports included in the antenna port group may be pre-agreed between the network device and the terminal device, or may be configured by the network device to the terminal device.
For example, taking X=8 as an example, in a case where K=1, one antenna port group includes all antenna ports; in a case where K=2, an antenna port group 0 includes antenna ports {0, 1, 4, 5}, and an antenna port group 1 includes antenna ports {2, 3, 6, 7}; in a case where K=4, an antenna port group 0 includes antenna ports {0, 4}, an antenna port group 1 includes antenna ports {1, 5}, an antenna port group 2 includes antenna ports {2, 6}, and an antenna port group 3 includes antenna ports {3, 7}. In a case where K=8, an antenna port group k includes antenna port k, where the value of k is 0, 1, . . . , 7.
In another implementation, the terminal device reports the number K of antenna port groups contained in the X antenna ports to a network device, where K is used to determine at least one of the number N of the PTRS ports, the antenna port and the transport layer associated with the each PTRS port, or the power boosting value of the each PTRS port. That is, the network device and the terminal device have the same understanding of the number K of the antenna port groups.
Embodiment 1-2: the number N of the PTRS ports is configured by the network device, where N is less than or equal to K.
For example, the terminal device may report the capability related to the PTRS port to the network device, and the network device may determine the number N of the PTRS ports based on the capabilities related to PTRS port reported by the terminal device.
Optionally, the capability related to PTRS port may include the number of PTRS ports expected (or required) or supported by the terminal device, and/or the number K of antenna port groups included in the X antenna ports.
It should be noted that the number N of PTRS ports herein may be a maximum number of PTRS ports used for the uplink transmission of X antenna ports. The number of PTRS ports actually used needs to be determined based on antenna ports actually used to transmit data (e.g., PUSCH), for example, based on TPMI indication information.
Therefore, in the embodiments of the present disclosure, in a case where uplink 8-antenna port transmission is supported, the terminal device may determine the appropriate number N of PTRS ports based on the number K of the antenna port groups included in the X antenna ports, so that different numbers of PTRS ports may be determined for different antenna port grouping manners, thereby ensuring the phase tracking performance of the uplink 8-antenna port transmission under different antenna arrays.
In the following, in combination with embodiment 2, a method for determining the antenna port and the transport layer associated with the each PTRS port is described.
Embodiment 2: the determination of the antenna port and the transport layer associated with the PTRS port.
In some embodiments, the terminal device may determine the antenna port and the transport layer associated with the each PTRS port based on the coherent configuration of the codebook.
For example, in a case where the network device configures a full coherent codebook for the terminal device, the network device will only configure one PTRS port, where the one PTRS port will be associated with all antenna ports.
Embodiment 2-1: the antenna port associated with the each PTRS port is determined, based on the number K of the antenna port groups contained in the X antenna ports.
In some embodiments, the terminal device may determine the antenna port associated with the each PTRS port based on the number K of the antenna port groups contained in the X antenna ports and the coherent configuration of the codebook.
For example, in a case where the partial-coherent codebook is configured, the terminal device determines the antenna port associated with the each PTRS port based on the number K of the antenna port groups contained in the X antenna ports.
In some specific embodiments, in a case where the partial-coherent codebook is configured, the terminal device may determine the antenna port associated with the each PTRS port based on the number K of antenna port groups contained in the X antenna ports and a first association relationship. The first association relationship includes a relationship between the PTRS port and the antenna port in a case where K takes at least one value.
Taking X=8 as an example, the first association relationship may include at least one of association relationships:
Embodiment 2-2: the antenna port associated with the each PTRS port is determined based on configuration of the antenna port group.
For example, it is determined that each PTRS port is associated with one of the antenna port groups contained in the X antenna ports.
That is, antenna ports associated with one PTRS port include all antenna ports in one antenna port group.
Optionally, antenna ports contained in each antenna port group may be preconfigured by the network device. For example, in a case where X=8, the network device may be configured with 2 or 4 antenna port groups.
Embodiment 2-3: the antenna port associated with the each PTRS port is determined based on the number N of PTRS ports.
In some embodiments, the terminal device may determine the antenna port associated with the each PTRS port based on the number N of PTRS ports and a second association relationship. The second association relationship includes a relationship between the PTRS port and the antenna port in a case where N takes at least one value.
Taking X=8 as an example, the second association relationship may include at least one of association relationships:
Embodiment 2-4: the antenna port associated with the each PTRS port is determined based on the transport layer transmitted on the antenna port.
In some embodiments, the terminal device may determine that one PTRS port is associated with antenna ports that transmit the same transport layer. That is, antenna ports associated with the PTRS port are used to transmit the same transport layer.
For example, it is determined that a first PTRS port is associated with a first antenna port set, and a second PTRS port is associated with a second antenna port set, where antenna ports in the first antenna port set are all used to transmit a first transport layer, and antenna ports in the second antenna port set are all used to transmit a second transport layer, the first transport layer and the second transport layer are different PUSCH transport layers, the first antenna port set and the second antenna port set are different, and the first PTRS port is different from the second PTRS port.
That is, an antenna port associated with the PTRS port needs to be determined based on an antenna port actually used by the transport layer, for example, based on TPMI indication information.
For example, assuming that the precoding matrix indicated by the TPMI indication information is:
then antenna ports 0 and 4 for transmitting the first transport layer are associated with a PTRS port 0, and antenna ports 1 and 5 for transmitting the second transport layer are associated with a PTRS port 1.
For another example, assuming that the precoding matrix indicated by the TPMI indication information is:
then antenna ports {0, 1, 4, 5} for transmitting the first transport layer are associated with a PTRS port 0, and antenna ports {2, 3, 6, 7} for transmitting the second transport layer are associated with a PTRS port 1.
For another example, assuming that the precoding matrix indicated by the TPMI indication information is:
then antenna ports {0, 2, 4, 6} for transmitting the first transport layer are associated with a PTRS port 0, and antenna ports {1, 3, 5, 7} for transmitting the second transport layer are associated with a PTRS port 1.
Therefore, in embodiments 2 to 4, an association relationship between the antenna port and the PTRS port is not fixed, and is determined based on the antenna port actually used for transport layer transmission in the precoding matrix indicated by the TPMI indication information.
In some embodiments of the present disclosure, the antenna port associated with the each PTRS port may be used to determine the number M of PTRS ports actually used for the uplink transmission of X antenna ports and/or the DMRS port associated with the PTRS port.
In some embodiments, the method 200 further includes:
For example, a number of all PTRS ports associated with the antenna ports corresponding to a non-zero element in the precoding matrix indicated by the TPMI indication information is determined as a number M of PTRS ports actually used for the uplink transmission of X antenna ports.
In some embodiments, the number M of PTRS ports actually used for the uplink transmission of X antenna ports may be used to determine the PTRS actually transmitted, that is, the terminal device actually only needs to transmit M PTRS ports instead of N PTRS ports.
In some embodiments, the number M may be used to determine the DMRS ports associated with the PTRS, that is, the terminal device only needs to determine the DMRS ports associated with the M PTRS ports actually transmitted, and does not need to determine the DMRS ports associated with the N PTRS ports. The specific determination manner is described below.
In some embodiments, the number M may be used to determine the power boosting value of the PTRS port. For example, N in the table or formula exemplified below may be replaced by the number M.
As an example, it is assumed that the precoding matrix indicated by the TPMI indication information is:
and the antenna ports {0, 1, 4, 5} are associated with a PTRS port 0, and antenna ports {2, 3, 6, 7} are associated with a PTRS port 1, then since the above 8 antenna ports are all used to transmit data (the corresponding rows contain non-zero elements), the actual number M of PTRS ports is equal to 2.
As another example, it is assumed that the precoding matrix indicated by the TPMI indication information is:
and the antenna ports {0, 1, 4, 5} are associated with a PTRS port 0, and the antenna ports {2, 3, 6, 7} are associated with a PTRS port 1, then since only the antenna ports {0, 1, 4, 5} are used to transmit data (the corresponding rows contain non-zero elements), at this time, the actual number M of PTRS ports is equal to 1, that is, only PTRS port 0 is actually used for transmission.
Embodiment 2-5: the transport layer associated with the PTRS port is determined based on the transport layer transmitted on the antenna port associated with the PTRS port.
In some embodiments, the S220 includes:
The DMRS-PTRS association indication information is used to indicate an association relationship between the DMRS port and the PTRS port.
That is, in a case where a plurality of transport layers are transmitted on the antenna port associated with a PTRS port, that is, in a case where the first transport layer set includes the plurality of transport layers, the terminal device may determine the target transport layer associated with the PTRS port from the plurality of transport layers based on the DMRS-PTRS association indication information.
Optionally, if at most two transport layers are transmitted on an antenna port associated with the first PTRS port, 1-bit DMRS-PTRS association indication information may be used to indicate a target transport layer associated with the first PTRS port and in the two transport layers.
Optionally, if at most four transport layers are transmitted on an antenna port associated with the first PTRS port, 2-bit DMRS-PTRS association indication information may be used to indicate a target transport layer associated with the first PTRS port and in the four transport layers.
Optionally, if at most eight transport layers are transmitted on an antenna port associated with the first PTRS port, 3-bit DMRS-PTRS association indication information may be used to indicate a target transport layer associated with the first PTRS port and in the eight transport layers.
In some embodiments, the method 200 further includes:
That is, in a case where a plurality of DMRS ports are transmitted on the antenna port associated with a PTRS port, that is, in a case where the first DMRS port set includes a plurality of DMRS ports, the terminal device may determine the target DMRS port associated with the PTRS port in the plurality of DMRS ports based on the DMRS-PTRS association indication information.
Optionally, if at most two DMRS ports are transmitted on an antenna port associated with the first PTRS port, 1-bit DMRS-PTRS association indication information may be used to indicate a target DMRS port associated with the first PTRS port and in the two DMRS ports.
Optionally, if at most four DMRS ports are transmitted on an antenna port associated with the first PTRS port, 2-bit DMRS-PTRS association indication information may be used to indicate a target DMRS port associated with the first PTRS port and in the four DMRS ports.
Optionally, if at most eight DMRS ports are transmitted on an antenna port associated with the first PTRS port, 3-bit DMRS-PTRS association indication information may be used to indicate a target DMRS port associated with the first PTRS port and in the eight DMRS ports.
In some embodiments, if one PTRS port is associated with one transport layer, the PTRS port is also associated with a DMRS port used by the transport layer. Further, the DMRS port of the transport layer is used to transmit the PTRS port, that is, the PTRS port and the associated DMRS port use the same sequence, frequency domain position, precoding matrix and beam. That is, the signal transmitted on the PTRS port and the signal transmission manner are the same as those of the associated DMRS port, so that the receiving end may perform joint channel estimation or phase estimation by using the signals on the associated DMRS port and the PTRS port.
As an example, it is assumed that the precoding matrix indicated by the TPMI indication information is:
where two transport layers are transmitted on the antenna ports {0, 1, 4, 5} associated with a PTRS port 0, and one transport layer is transmitted on the antenna ports {2, 3, 6, 7} associated with a PTRS port 1, then at this time, the terminal device may determine the one transport layer associated with the PTRS port 0 in the two transport layers transmitted on the antenna port associated with PTRS port 0 based on the DMRS-PTRS association indication information in DCI, and use the DMRS port used by the transport layer to transmit the PTRS port 0.
Therefore, in the embodiments of the present disclosure, in a case where the uplink 8-antenna port transmission is supported, the terminal device may determine a mapping relationship between the PTRS port and the 8 antenna ports, so that different mapping manners may be determined for different antenna port grouping manners, thereby supporting the uplink 8-antenna port transmission under different antenna arrays.
In some embodiments of the present disclosure, the power boosting value is a boosting value of the transmit power of one PTRS port relative to the transmit power of the DMRS port or transport layer associated with the PTRS port. In a case where the PTRS port is transmitted, there are two main reasons why the PTRS needs to be powered up:
In the following, in conjunction with embodiment 3, a method for determining the power boosting value of each PTRS port is described.
Embodiment 3: the determination of the power boosting value of the PTRS port.
In some embodiments, the terminal device may determine the power boosting value of the each PTRS port based on the number K of the antenna port groups contained in the X antenna ports and/or the number of transport layers of the PUSCH to be transmitted and/or the number N of configured PTRS ports.
In some embodiments, the terminal device determines the power boosting value of the each PTRS port based on the coherent configuration of the codebook, the number K of antenna port groups contained in the X antenna ports and/or the number of transport layers of the PUSCH to be transmitted.
For example, in a case where a partial-coherent codebook is configured, the terminal device determines the power boosting value of the each PTRS port based on the number K of antenna port groups contained in the X antenna ports and/or the number of transport layers of the PUSCH to be transmitted.
Exemplarily, the power boosting value is 10*lg (N) dB in a case where the number of transport layers of the PUSCH is 2 or 3.
Exemplarily, the power boosting value is 10*lg (4N/K) dB in a case where the number of transport layers of the PUSCH is 4 or 5.
Exemplarily, the power boosting value is 10*lg (N*└6/K┘) in a case where the number of transport layers of the PUSCH is 6 or 7.
Exemplarily, the power boosting value is 10*lg 10*lg (8N/K) dB in a case where the number of transport layers of the PUSCH is 8.
Exemplarily, the power boosting value is 3N−3+10*lg (└L/2┘) dB in a case where K=2 and the number of transport layers of the PUSCH is 2 to 8, where L is the number of transport layers of the PUSCH.
Exemplarily, the power boosting value is 3N−3+3*└L/8┘ in a case where K=4 and the number of transport layers of the PUSCH is 2 to 8, where L is the number of transport layers of the PUSCH.
For another example, in a case where the full coherent codebook is configured, the network device configures only one PTRS port for the terminal device, and the terminal device may determine that the power boosting value on the PTRS port is 10*lg (L) dB, where L represents the number of transport layers of the PUSCH.
For another example, in a case where the non-coherent codebook is configured or non-codebook transmission is configured, the terminal device may determine that the power boosting value of each PTRS port is 10*lg (N) dB. Optionally, if the maximum allowed number Nmax of PTRS ports is 2, 10*lg (N) dB may also be expressed as 3N−3.
Optionally, if the maximum allowed number Nmax of PTRS ports is 4, the terminal device may determine the power boosting value of the each PTRS port in the manner described in the following embodiment 3-1. The maximum number of the PTRS ports may be predefined or configured by the network device.
Optionally, if the maximum allowed number Nmax of PTRS ports is 2, the terminal device may determine the power boosting value of the each PTRS port in the manner described in the following embodiment 3-2, or, may determine the power boosting value of the each PTRS port in the manner described in the following embodiment 3-1. The maximum number of PTRS ports may be predefined or configured by the network device.
Embodiment 3-1: applicable to a case where the maximum allowed number Nmax of PTRS ports is 4, that is, a value range of N is {1, 2, 4}.
At this time, assuming that the value of K is 2 or 4, in a case where the number of transport layers L of the PUSCH is greater than 1, the power boosting value may be determined in the following manner.
As an example, in a case where the number of transport layers of the PUSCH is 2 or 3, the power boosting value of each PTRS port is determined to be 10*lg (N) dB, where N is the number of PTRS ports.
As another example, in a case where the number of transport layers of the PUSCH is 4 or 5, the power boosting value of each PTRS port is determined to be 10*lg (4N/K) dB. For example, in a case where K=2, the power boosting value of the each PTRS port is 10*lg (2N) dB; in a case where K=4, the power boosting value of each PTRS port is 10*lg (N) dB.
As another example, in a case where the number of transport layers of PUSCH is 6 or 7, the power boosting value of each PTRS port is determined to be 10*lg (N*└6/K┘) dB, where └ ┘ represents rounding down, and the rounding down herein may also be replaced by other rounding manners, such as rounding up, rounding off, or the like. For example, in a case where K=2, the power boosting value of the each PTRS port is 10*lg (3N) dB; in a case where K=4, the power boosting value of each PTRS port is 10*lg (N) dB.
As another example, in a case where the number of transport layers of PUSCH is 8, the power boosting value of each PTRS port is 10*lg (8N/K) dB. For example, in a case where K=2, the power boosting value of each PTRS port is 10*lg (4N) dB; in a case where K=4, the power boosting value of each PTRS port is 10*lg (2N) dB.
Table 2 is an example of the power boosting value in a case where the number of transport layers of the PUSCH is 1 to 4, and Table 3 is an example of the power boosting value in a case where the number of transport layers of the PUSCH is 5 to 8.
Embodiment 3-2: applicable to a case where the maximum allowed number Nmax of PTRS ports is 2, that is, a value range of N is (1,2).
In this case, different power boosting values may be determined based on whether the value of K is 2 or 4.
In some embodiments, in a case where K=2 and the terminal device determines that the number of transport layers of the PUSCH is 2 to 8, the power boosting value of each PTRS port is 3N−3+10*lg (└L/2┘) dB, where L is the number of transport layers of the PUSCH.
Exemplarily, in a case where the number of transport layers is 2 or 3, the power boosting value of the each PTRS port is 3N−3.
Exemplarily, in a case where the number of transport layers is 4 or 5, the power boosting value of the each PTRS port is 3N.
Exemplarily, in a case where the number of transport layers is 6 or 7, the power boosting value of the each PTRS port is 3N+1.77 (or 1.76/1.78).
Exemplarily, in a case where the number of transport layers is 8, the power boosting value of the each PTRS port is 3N+3.
Table 4 is an example of the power boosting value in a case where the number of transport layers of the PUSCH is 1 to 4, and Table 5 is an example of the power boosting value in a case where the number of transport layers of the PUSCH is 5 to 8.
In some other embodiments, in a case where K=4 and the terminal device determines that the number of transport layers of the PUSCH is 2 to 8, the power boosting value of the each PTRS port is 3N−3+3*└L/8┘, where L is the number of transport layers of the PUSCH. Table 6 is an example table of power boosting values in a case where the number of transport layers of the PUSCH is 1 to 4, and Table 7 is a comparison table of power boosting values in a case where the number of transport layers of the PUSCH is 5-8.
For example, in a case where the number of transport layers of the PUSCH is 2-7, the power boosting value of the each PTRS port is 3N−3.
For another example, in a case where the number of transport layers of the PUSCH is 8, the power boosting value of the each PTRS port is 3N.
In some embodiments, 7.78 in the above table may also be expressed as 7.77, and 1.77 may also be expressed as 1.76 or 1.78.
It should be noted that the above table only gives a general expression of the power boosting values. In practical applications, other expressions may also be used, as long as power boosting values corresponding to different transport layers obtained at last are the same as the values obtained by the above expressions or tables. The embodiments of the present disclosure do not limit the specific expression manner. For example, in Table 3, in a case where the number of transport layers is 6 or 7, 10*lg (N)+10*lg (└6/K┘) may also be expressed as 10*lg (N)+10*lg (5−K) or 10*lg (N)+10*lg (8/K−1).
Therefore, in embodiments of the present disclosure, in a case where the uplink 8-antenna port transmission is supported, the terminal device may determine the power boosting value of each PTRS port, so as to ensure that power on different orthogonal frequency-division multiplexing (OFDM) symbols is constant in the 8-antenna port transmission under different antenna array conditions, thereby ensuring the RF performance, and the power boosting is beneficial to enhancing the measurement performance on the PTRS port.
