Description

Transmission power indication method of uplink phase tracking reference signal and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for indicating transmit power of an uplink phase tracking reference signal and a related device.

Background

With the development of mobile communication service demand, organizations such as ITU (International telecommunications Union) and 3GPP have started to research New wireless communication systems (e.g., 5G NR, 5Generation New RAT). In addition to codebook-based uplink transmission, the new wireless communication system supports non-codebook-based uplink transmission. For uplink transmission not based on a codebook, a user terminal sends one or more SRS (Sounding Reference Signal) resources according to the configuration of a network side device. And the network side equipment measures one or more SRS resources sent by the user terminal, selects one or more SRS resources, allocates a DMRS port to each selected SRS resource, and indicates the SRS resource selection and DMRS port allocation information to the user terminal. The user terminal performs corresponding PUSCH (Physical Uplink Shared Channel) transmission and Uplink PT-RS (Phase-tracking Reference Signals) transmission according to the SRS resource and the DMRS port indicated by the network side device. In this transmission mode, each SRS resource is transmitted through precoding, which is determined by the terminal itself and does not need to inform the network side device. And after the user terminal receives the SRS resource and the DMRS port information indicated by the network side equipment, determining the number of the PUSCH transmission layers according to the number of the indicated SRS resource, wherein each layer corresponds to the DMRS port allocated to one SRS resource, and the precoding adopted by the SRS resource is used for transmission. And each PT-RS port is mapped to a DMRS port allocated by one SRS resource, and the precoding adopted by the SRS resource is used for transmission. Since precoding is determined by the user terminal, the network side device cannot know the transmission structure of uplink transmission at this time. Therefore, the transmission power of the uplink PT-RS at this time cannot be determined, and thus correct data demodulation cannot be performed, which affects system performance. Therefore, there is a need to solve the problem of the transmission power indication of uplink PT-RS by non-codebook based uplink transmission.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a User Equipment (UE) 11 and a network side device 12, where the UE 11 may be a terminal side device such as a mobile phone or a vehicle-mounted terminal, and it should be noted that a specific type of the UE 11 is not limited in the embodiment of the present invention. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, or the network side device 12 may be an Access Point (AP); the base station may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) whose management is controlled. It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.

Referring to fig. 2, fig. 2 is a flowchart of a method for indicating transmit power of an uplink phase tracking reference signal according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

step 201, reporting target information to a network side device, where the target information includes uplink transmission type information or uplink phase tracking reference signal PT-RS sending power information, and the target information is used for the network side device to determine the sending power of the uplink PT-RS.

The method for indicating the transmission power of the uplink phase tracking reference signal provided by the embodiment is mainly applied to a user terminal and is used for indicating the transmission power of an uplink PT-RS in a non-codebook-based uplink transmission process.

The Uplink communication CHannel reported by the target information may be a PUCCH (Physical Uplink Control CHannel) or a PUSCH. The determination of the target information can be selected by the user terminal, or configured by the network side device, or agreed by a protocol. Specifically, the target information is used to indicate the transmission power of the uplink PT-RS. That is, after receiving the target information reported by the user terminal, the network side device may determine the sending power of the uplink PT-RS according to the target information.

It should be noted that the manner in which the user terminal determines the uplink transmission type information and the transmission power information is different, and this will be described in detail below.

In the first embodiment, if the ue determines to report using the transmission power information as the target information, the ue needs to determine the transmission power information before reporting. Specifically, in the present embodiment, before the step 201, the following steps may be included:

and determining the sending power information according to the SRS resource indication information of the channel sounding reference signal, the DMRS port indication information of the demodulation reference signal and the mapping information of the uplink PT-RS.

The SRS resource indication information and the DMRS port indication information may be sent to the user equipment by the network side device through physical layer signaling.

The mapping information of the uplink PT-RS comprises a mapping relation between a PT-RS port and the DMRS port, or the mapping information of the uplink PT-RS comprises a mapping relation between the PT-RS port and SRS resources.

The mapping information of the uplink PT-RS is agreed by a protocol, or the mapping information of the uplink PT-RS is sent to a user terminal by the network side equipment through physical layer signaling.

Next, the transmission power information may be an implicit indication or an explicit indication. In this embodiment, the transmission power information is a transmission power value or an index value in a transmission power value set predefined by the system.

For example, the set of uplink PT-RS transmit power values may be configured by a protocol or a network side device. If the uplink PT-RS transmission power value set S includes 4 values, S ═ 0, -3, -4.77, -6. When the transmission power information is an index value 1, the transmission power value is 0; when the transmission power information is an index value of 3, the transmission power value is represented as-3; when the transmission power information is an index value of 3, the transmission power value is represented as-4.77; when the transmission power information is an index value of 4, it indicates that the transmission power value is-6.

It should be understood that the ue reports the transmit power information as the target information, and the network side device receives the transmit power information and can directly determine the transmit power value.

In the second embodiment, if the user terminal determines to report using the uplink transmission type information as the target information, the corresponding relationship between the transmission type and the transmission power of the uplink PT-RS needs to be agreed by a protocol; before reporting, the uplink transmission type needs to be determined first. Specifically, in the present embodiment, before the step 201, the following steps may be included:

It should be noted that the target transmission types may include coherent transmission, partially coherent transmission, and non-coherent transmission, and may also include other transmission types, which are not listed here. Each uplink transmission type may correspond to one or more transmit power values. When one uplink transmission type is adopted to correspond to multiple transmission power values, the network side device may determine the transmission power values according to the number of SRS resources (corresponding to the number of layers of PUSCH transmission) selected and indicated to the user terminal. Specifically, the network side device may determine the sending power of the uplink PT-RS according to the target transmission type indicated by the uplink transmission type information, the measurement result of the SRS resource transmitted by using the target transmission type, and the correspondence.

In the embodiment of the invention, target information is reported to a network side device, the target information comprises uplink transmission type information or uplink phase tracking reference signal (PT-RS) sending power information, and the target information is used for the network side device to determine the sending power of the uplink PT-RS. Because the target information is actively reported by the user terminal, the network side equipment determines the sending power of the uplink PT-RS based on the target information, thereby being capable of carrying out correct data demodulation in the uplink transmission process which is not based on the codebook.

Referring to fig. 3, an embodiment of the present invention further provides a method for indicating a transmission power of an uplink phase tracking reference signal, as shown in fig. 3, including the following steps:

step 301, receiving target information reported by a user terminal, where the target information includes uplink transmission type information or uplink phase tracking reference signal PT-RS sending power information, and the target information is used for the network side device to determine the sending power of the uplink PT-RS.

And step 302, determining the sending power of the uplink PT-RS according to the target information.

The uplink communication channel reported by the target information may be a PUCCH or a PUSCH. The determination of the target information can be selected by the user terminal, or configured by the network side device, or agreed by a protocol. Specifically, the target information is used to indicate the transmission power of the uplink PT-RS. That is, after receiving the target information reported by the user terminal, the network side device may determine the sending power of the uplink PT-RS according to the target information.

In the first embodiment, if the ue determines to report using the transmission power information as the target information, the ue first needs to determine the transmission power information before reporting. Specifically, the transmission power information is determined according to the SRS resource indication information of the channel sounding reference signal, the DMRS port indication information of the demodulation reference signal, and the mapping information of the uplink PT-RS.

In another embodiment, if the user terminal determines to report using the uplink transmission type information as the target information, the corresponding relationship between the transmission type and the transmission power of the uplink PT-RS needs to be agreed by a protocol; before reporting, the uplink transmission type needs to be determined first. Specifically, the user terminal may receive configuration information sent by the network side device, where the configuration information is used to indicate configuration of SRS resources; and determining the uplink transmission type used by the SRS resource, wherein the transmission type is agreed by a protocol, or selected by a user terminal, or configured by network side equipment.

It should be noted that the target transmission types may include coherent transmission, partially coherent transmission, and non-coherent transmission, and may also include other transmission types, which are not listed here. Each uplink transmission type may correspond to one or more transmit power values. When one uplink transmission type is adopted to correspond to multiple transmission power values, the network side device may determine the transmission power values according to the number of SRS resources (corresponding to the number of layers of PUSCH transmission) selected and indicated to the user terminal. Specifically, step 302 includes: and determining the sending power of the uplink PT-RS according to the target transmission type indicated by the uplink transmission type information, the measurement result of the SRS resource transmitted by using the target transmission type and the corresponding relation.

And step 303, demodulating the uplink data according to the determined transmission power.

In this embodiment, after the transmission power is determined, correct data demodulation may be performed in the non-codebook-based uplink transmission process according to the determined transmission power.

In the embodiment of the invention, target information reported by a user terminal is received, wherein the target information comprises uplink transmission type information or transmission power information of an uplink phase tracking reference signal (PT-RS), and the target information is used for the network side equipment to determine the transmission power of the uplink PT-RS; determining the sending power of the uplink PT-RS according to the target information; and demodulating the uplink data according to the determined transmission power. Because the target information is actively reported by the user terminal, the network side equipment determines the sending power of the uplink PT-RS based on the target information, thereby being capable of carrying out correct data demodulation in the uplink transmission process which is not based on the codebook.

For better understanding of the present invention, two different implementations in which the target information includes the transmission power information of the uplink PT-RS and the target information includes the uplink transmission type information are described in detail below.

In the first case, the target information includes transmission power information of the uplink PT-RS.

In the first case, the set of uplink PT-RS transmit power values may be agreed in advance by the protocol. Thus, the uplink PT-RS transmission power value set S includes 4 values, where S ═ 0, -3, -4.77, -6. And the protocol also appoints the mapping relation between the PT-RS and the DMRS ports in advance, for example, the PT-RS port can only be mapped to the DMRS port with the lowest index number. The specific implementation process of the sending power value indication of the uplink PT-RS is as follows:

the first step is as follows: and the network side equipment configures T SRS resources transmitted by the user terminal and indicates the resources to the user terminal through a high-layer or physical layer signaling.

The second step is that: and the network side equipment measures the T SRS resources transmitted by the user terminal and indicates the M SRS resources to the user terminal through a physical layer signaling.

The third step: the network side equipment configures M DMRS ports for the user terminal, each SRS resource corresponds to one DMRS port, and the M DMRS ports are indicated to the user terminal through physical layer signaling.

The fourth step: and the user terminal determines that the uplink PT-RS uses the DMRS port related to the uplink PT-RS for transmission according to protocol convention, and determines the sending power value of the PT-RS at the moment. As shown in fig. 4, it is assumed that the network side device configures 4 SRS resources, which are denoted by SRS0, SRS1, SRS2, and SRS3 for user terminal transmission T. The user terminal determines the resource SRS0 according to the measurement result of the downlink channel by utilizing the channel reciprocity, the SRS1 and the SRS2 use equivalent ports which are virtualized by 3 antenna ports for transmission, and the resource SRS3 uses 1 antenna port which is not virtualized for transmission. The network side equipment determines to select M-3 SRS resources from the 4 SRS resources according to the measurement results, wherein the M-3 SRS resources are SRS0, SRS2 and SRS 3. The network side equipment is respectively configured with three ports of DMRS0, DMRS1 and DMRS2 for the 3 SRS resources. The user terminal receives SRS resource { SRS0, SRS2, SRS3} and DMRS port { DMRS0, DMRS1, DMRS2} information indicated by the network equipment through physical layer signaling, and determines that the SRS0 corresponds to the DMRS0, the SRS2 corresponds to the DMRS1 and the SRS3 corresponds to the DMRS2 according to one corresponding relation. And according to the system definition that the PT-RS port can only be mapped to the DMRS port with the lowest index number, the PT-RS is mapped to the port of the DMRS0 for transmission. Such as the configuration shown in fig. 4. The user terminal may determine the PT-RS transmission power value to be-3 at this time. And meanwhile, determining that the PUSCH adopts 3-layer transmission, and mapping each layer to one DMRS port for transmission.

The fifth step: and the user terminal reports the sending power value of the uplink PT-RS to the network side equipment through an uplink PUSCH channel. Specifically, the second transmission power value in the transmission power set S may be indicated using 2-bit information 01. This 2-bit information 01 is transmitted on the PUSCH channel multiplexed with user data.

In a second case, the target information includes uplink transmission type information.

In the second case, the protocol defines in advance the correspondence between the uplink transmission type and the transmission power of the uplink PT-RS, specifically, the correspondence is shown in table 1 below:

type of transmission	Layer 1 PUSCH	2-layer PUSCH	3-layer PUSCH	4-layer PUSCH
					Coherence	0	-3	-4.77	-6
Partial coherence	0	0	0	-3
					Non-coherent	0	0	0	0
Reservation	-	-	-	-

TABLE 1

Based on the corresponding relationship in the table, the specific implementation process of indicating the sending power value of the uplink PT-RS is as follows:

The second step is that: the user terminal determines the uplink transmission type adopted by the transmission of the T SRS resources and the precoding information of each SRS resource when the uplink transmission type is adopted by the user terminal, and transmits the T SRS resources; the uplink transmission type comprises at least one uplink transmission type of coherent transmission, partially coherent transmission and non-coherent transmission. The user terminal can determine the uplink transmission type and the precoding information according to the reciprocity of the uplink and downlink signals.

The third step: and the user terminal simultaneously reports the uplink transmission type information adopted by the T SRS resource transmissions. Specifically, the indication may be performed by using 2-bit information, and the uplink transmission type information may be reported in a PUCCH or a PUSCH channel.

The fourth step: the network side equipment measures T SRS resources transmitted by the user terminal, determines M SRS resources, and then indicates the M SRS resource indexes to the user terminal through physical layer signaling.

The fifth step: the network side equipment is M DMRS ports, and each DMRS port corresponds to one SRS resource. And simultaneously determining that each PT-RS port is mapped to one of the M DMRS ports. And informing the terminal of the indexes of the M DMRS ports and the mapping information of the PT-RS ports through physical layer signaling.

And a sixth step: and the network side equipment receives the transmission type information reported by the user terminal. And according to the value of M determined in the fourth step, the number of the layers of the PUSCH transmitted by the corresponding user terminal is determined, so that the sending power of the uplink PT-RS is determined. For example, if the transmission type reported by the ue is partially coherent and the network side device determines that M is 4, the network side device determines that the uplink PT-RS transmission power value is-3 dB in table 1.

The seventh step: the user terminal receives M SRS resource indexes, M DMRS port indexes and mapping information of the PT-RS port indicated by the network side equipment through physical layer signaling, determines that the PT-RS is transmitted on the corresponding DMRS port, and transmits the uplink PT-RS by using-3 dB as a sending power value according to the table 1. And meanwhile, determining that the PUSCH adopts M layers for transmission, and mapping each layer to one DMRS port for transmission.

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
