[0182] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0183] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0184] The technical solution provided in the embodiments of the present application can be applicable to a variety of systems, such as a 5G system.

[0185] Among them, the terminal involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called a UE. A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

[0186] The network device involved in the embodiment of the present application may be a base station gNB, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0187] For example, in an embodiment of the present application, one or more antennas may be used between the network device and the terminal device for multiple input multiple output (MIMO) transmission, and the MIMO transmission may be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of the antenna combination, the MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, mMIMO or massive-MIMO, or it may be diversity transmission, precoded transmission or beamforming transmission, etc.

[0188] The method for determining the power enhancement factor provided in the embodiment of the present application can be applied to the transmission mode of single transmit receive point and multi-panel (STxMP).

[0189] When the terminal transmits in the space division multiplexing (SDM) of STxMP, the terminal needs to determine the power boosting coefficient of its uplink phase tracking reference signal (PTRS) based on the high-level parameters configured by the network equipment, and implement the power boosting configured by the network equipment for it based on the power boosting coefficient, so as to better perform SDM transmission.

[0190] At present, the power enhancement factor determination in the protocol is designed only for the scenario of single antenna panel transmission of the terminal, and is not applicable to the scenario of simultaneous transmission of multiple panels of the terminal. For example, the existing design assumes that power can be borrowed between all PUSCH layers when the Physical Uplink Shared Channel (PUSCH) transmission is fully coherent. However, in the SDM mode of STxMP, considering that power may not be borrowed between different panels, this assumption is no longer valid. If the existing design is continued, the terminal may not be able to accurately determine the power enhancement factor, and thus cannot implement the power enhancement configured by the network device based on the determined power enhancement factor.

[0191] In order to enable the terminal to accurately determine the power enhancement coefficient, thereby realizing the power enhancement configured by the network device for it, the embodiment of the present application provides a method for determining the power enhancement coefficient. When performing power enhancement, by receiving high-level configuration information sent by the network device, the high-level configuration information includes the number of layers of the channel transmission resources scheduled by the target object, and the target object includes the terminal, or multiple associated objects associated with the phase tracking reference signal PTRS port of the terminal; and based on the high-level configuration information, the power enhancement coefficient of the target object is determined; and then based on the power enhancement coefficient, the transmission power of the PTRS port of the target object is enhanced. In this way, the terminal or multiple associated objects are associated with the number of layers of the scheduled channel transmission resources, so that the terminal can accurately determine the power enhancement coefficient of the terminal or multiple associated objects based on the high-level configuration information, thereby effectively realizing the power enhancement configured by the network device for it.

[0192] Below, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0193] Figure 1 A schematic diagram of a method for determining a power enhancement factor provided in an embodiment of the present application is provided, which can be applied to a terminal. For example, see Figure 1 As shown, the method for determining the power enhancement factor may include:

[0194] S101. Receive high-level configuration information sent by a network device, where the high-level configuration information includes the number of layers of channel transmission resources scheduled for a target object, and the target object includes a terminal, or multiple associated objects associated with a phase tracking reference signal PTRS port of the terminal.

[0195] For example, in an embodiment of the present application, when the target object is a terminal, power borrowing shall not be performed between panels. Therefore, it is not necessary to perform power enhancement for a single panel. In this case, the number of layers of channel transmission resources scheduled by the terminal is the sum of the number of layers of channel transmission resources corresponding to multiple associated objects in the terminal. If the number of multiple associated objects is two, and each associated object corresponds to a channel sounding reference signal (Sounding Reference Signal, SRS) resource set (SRS resource set), then the number of layers of channel transmission resources scheduled by the terminal is It is the sum of the number of layers of PUSCH resources corresponding to the two SRS resource sets respectively, thereby determining the number of layers of channel transmission resources scheduled by the terminal.

[0196] When the target object is multiple associated objects, power can be borrowed between panels. In each combination of layer number and coherence, it is necessary to consider whether power can be borrowed from other panels. When the number of layers of the configured channel transmission resources is greater than 1, since different PTRS ports correspond to different panels and are sent on different resource elements (RE), power enhancement needs to consider the impact of the number of configured PTRS ports and the corresponding relationship between panels. Therefore, in this case, the number of layers of the channel transmission resources scheduled by the associated object is greater than 1. The number of layers of the corresponding channel transmission resources, that is, the number of layers of uplink PUSCH resources scheduled by the PTRS port in the associated object, that is, the number of layers of PUSCH resources corresponding to the SRS resource set associated with the PTRS port.

[0197] For example, in an embodiment of the present application, among multiple association objects, different association objects correspond to different numbers of layers of channel transmission resources.

[0198] For example, in the embodiment of the present application, the associated object may be understood as an antenna panel panel, and the antenna panel panel may be indicated by at least one of the following:

[0206] It can be understood that in the embodiment of the present application, the example of an associated object being able to be indicated by at least one of the above implicit indications is used for illustration only, and specific settings can be made according to actual needs. Here, this embodiment does not make any specific limitations.

[0207] After the terminal receives the number of layers of the channel transmission resource scheduled by the target object configured by the network device, the terminal or multiple associated objects can be associated with the number of layers of the scheduled channel transmission resource, so that the terminal can accurately determine the power enhancement factor of the terminal or multiple associated objects based on the high-level configuration information, that is, perform the following S102:

[0208] S102: Determine a power enhancement factor of a target object based on high-level configuration information.

[0209] For example, in an embodiment of the present application, when determining the power enhancement coefficient of the target object based on the high-level configuration information, the high-level configuration information may also include the coding bit state and coherence of the target object. The coding bit state is the code point, that is, in addition to configuring the number of layers of channel transmission resources scheduled for the target object to the terminal through the high-level configuration information, the network terminal also configures the terminal with parameters UL-PTRS-power and coherence used to indicate the code point, which can be set according to actual needs.

[0210] Typically, the code point indicated by the parameter UL-PTRS-power includes "00", "01", "10" and "11". When the code point value indicated by the parameter UL-PTRS-power is "00" or "01", the power enhancement factor is The value of is reserved and is not involved in the embodiments of this application.

[0211] Generally, codebook-based transmission has three types of coherence: full coherent, partial coherent, and non-coherent. Full coherence means that coherent transmission can be performed between PUSCHs; partial coherence means that only PUSCHs in a coherent transmission group can be coherently transmitted, and PUSCHs between coherent transmission groups cannot be coherently transmitted; non-coherent transmission means that coherent transmission cannot be performed between all PUSCHs.

[0212] For example, in the embodiment of the present application, the coherence is generally determined by the network device based on at least one of the following:

[0213] The terminal's coherence capability information;

[0214] Codebook type;

[0215] The coherence type of the channel transmission resource.

[0216] It can be understood that in the embodiments of the present application, the determination of coherence based on at least one of the coherence capability information of the terminal, the codebook type, or the coherence type of the channel transmission resource is used as an example for explanation, and specific settings can be made according to actual needs.

[0217] When the network device determines the coherence of the terminal through the coherence capability information of the terminal, the terminal can report its coherence capability information to the network terminal. For example, the terminal reports the coherence capability information of 0 to the network device, which can indicate irrelevant; the terminal reports the coherence capability information of 1 to the network device, which can indicate partial coherence; the terminal reports the coherence capability information of 2 to the network device, which can indicate full coherence, etc. The specific settings can be made according to actual needs. Here, the embodiments of the present application are only illustrated by taking the coherence capability information of 0, 1 and 2 as examples, but it does not mean that the embodiments of the present application are limited to this.

[0218] When the network device codebook type determines the coherence of the terminal, for example, the codebook type may be the codebook type of the codebook reported by the terminal. The terminal may report to the network device the codebook subset to which the corresponding coherence belongs. For example, for a 2Tx transmission scenario, the codebook subset to which the coherence belongs may refer to and As shown, is an optional irrelevant codebook, is an optional fully coherent codebook.

[0219] For another example, for the 4Tx transmission scenario, the codebook subset to which the coherence belongs can be found in and As shown, is an optional irrelevant codebook, is an optional partially coherent codebook, is an optional fully coherent codebook.

[0220] For another example, for the 8Tx transmission scenario, the codebook subset to which the coherence belongs can be found in and As shown, is an optional irrelevant codebook, is an optional partially coherent codebook, is an optional fully coherent codebook.

[0221] After receiving the codebook reported by the terminal, the network device may determine the coherence of the terminal based on the codebook type of the reported codebook.

[0222] S103: Based on the power enhancement coefficient, enhance the transmission power of the PTRS port of the target object.

[0223] For example, when the target object is a terminal, the transmission power of the PTRS port of the terminal can be enhanced based on the power enhancement coefficient of the terminal; when the target object is an associated object associated with the PTRS port of the terminal, the transmission power of the PTRS port of the associated object can be enhanced based on the power enhancement coefficient of the associated object. The specific settings can be made according to actual needs.

[0224] It can be seen that in the embodiment of the present application, when power enhancement is performed, the high-level configuration information sent by the network device is received, and the high-level configuration information includes the number of layers of the channel transmission resources scheduled for the target object, and the target object includes a terminal, or multiple associated objects associated with the phase tracking reference signal PTRS port of the terminal; and based on the high-level configuration information, the power enhancement coefficient of the target object is determined; and then based on the power enhancement coefficient, the transmission power of the PTRS port of the target object is enhanced. In this way, the terminal or multiple associated objects are associated with the number of layers of the scheduled channel transmission resources, so that the terminal can accurately determine the power enhancement coefficient of the terminal or multiple associated objects based on the high-level configuration information, thereby effectively realizing the power enhancement configured by the network device for it.

[0225] Based on the above Figure 1 In order to facilitate understanding of how to determine the power enhancement factor of the target object based on the high-level configuration information in the above S102, the following will be described. Figure 2 The illustrated embodiments are described in detail.

[0226] Figure 2 A flowchart of a method for determining a power enhancement factor of a target object based on high-level configuration information provided in an embodiment of the present application can be applied to a terminal. For example, see Figure 2 As shown, the method may include:

[0227] S201. Searching for target power boost factor indication information corresponding to high-level configuration information based on a mapping relationship between pre-configured coding bit states, coherence, the number of layers of channel transmission resources, and corresponding target power boost factor indication information.

[0228] In the embodiment of the present application, the mapping relationship between the code point, coherence and the number of layers of the channel transmission resource can be pre-configured for the terminal by the network device, so that after receiving the high-level configuration information, the terminal can determine the target power enhancement factor indication information corresponding to the high-level configuration information based on the mapping relationship.

[0229] For example, in an embodiment of the present application, the target power enhancement factor indication information may be a calculation formula corresponding to the power enhancement factor; or it may be a specific target power enhancement factor value, which may be set according to actual needs.

[0230] In a possible scenario, when the target power enhancement coefficient indication information is a calculation formula corresponding to the power enhancement coefficient, for example, refer to the following Table 1, when the target object is configured for power enhancement and the high-level parameter UL-PTRS-power is configured, the high-level parameter multipanelScheme = SDMscheme, and the high-level parameter maxRankSdm = 1, 2, only considering the maximum number of layers in the SDM transmission of STxMP is 2, the terminal can determine the target power enhancement coefficient of the target object based on the mapping relationship, and further calculate the power enhancement coefficient of the target object based on the calculation formula.

For STxMP transmission, when the code point indicated by UL-PTRS-power is "01", it means that the target object always assumes that full power transmission can be performed. Based on the mapping relationship between the code point, coherence, and the number of layers of channel transmission resources shown in Table 1, the power enhancement coefficient of the target object can be determined. The calculation formula is The terminal can be based on the formula Further calculate the power enhancement factor of the target object The power enhancement factor of the target object can be determined based on the number of layers of the channel transmission resources scheduled by the target object. When the code point indicated by UL-PTRS-power is "10" or "11", the power enhancement factor of the target object The value is retained.

In addition, in the embodiment of the present application, the number of layers of uplink PUSCH resources The number of layers and the coherence are determined based on the precoding codewords indicated by the first TPMI field and the second TPMI field, and can be specifically set according to actual needs.

[0257] Combined with the above table 2, when the code point indicated by UL-PTRS-power is "01" and the number of layers of uplink PUSCH resources scheduled by the target object is When the value is 1, the power enhancement factor of the target object The value of is 0, which is irrelevant to the coherence type of the terminal, indicating that no power enhancement is performed. For STxMP transmission, when the code point indicated by UL-PTRS-power is "01", it means that the target object always assumes that full power transmission can be performed.

[0267] In combination with the above two possible scenarios, the target power enhancement factor indication information can be determined, and then the following S202 can be further performed:

[0268] S202: Determine a power enhancement factor of a target object based on the target power enhancement factor indication information.

[0269] It can be seen that in the embodiment of the present application, when the terminal determines the power enhancement coefficient of the target object, it first determines the target power enhancement coefficient indication information corresponding to the high-level configuration information based on the mapping relationship between the pre-configured code points, coherence and the number of layers of the channel transmission resources; and after determining the power enhancement coefficient of the target object based on the target power enhancement coefficient indication information, the terminal or multiple associated objects are associated with the number of layers of the scheduled channel transmission resources, so that the terminal can accurately determine the power enhancement coefficient of the terminal or multiple associated objects based on the high-level configuration information, thereby effectively realizing the power enhancement configured by the network device for it.

[0270] In combination with the above embodiments, it can be seen that in the embodiments of the present application, when power enhancement is performed, two possible scenarios can be included. In one possible scenario, when the target object is a terminal, it can be understood as determining the power enhancement coefficient of the terminal in units of terminals, and based on the power enhancement coefficient of the terminal, the transmission power of the PTRS port of the terminal is power enhanced. In another possible scenario, when the target object is an associated object associated with the PTRS port of the terminal, it can be understood as determining the power enhancement coefficient of the associated object in units of the associated object, and based on the power enhancement coefficient of the associated object, the transmission power of the PTRS port of the associated object is power enhanced.

[0271] In order to facilitate understanding of the power enhancement method provided by the embodiment of the present application, the above two possible scenarios will be taken as an example, combined with the following 12 specific embodiments, to describe in detail how to achieve power enhancement of the transmission power of the PTRS port of the target object in the above two possible scenarios.

[0272] In a possible scenario, the target object is a terminal, that is, the power enhancement coefficient of the terminal is determined based on the terminal, and based on the power enhancement coefficient of the terminal, the transmission power of the PTRS port of the terminal is enhanced.

[0273] It is understandable that in this possible scenario, considering that power borrowing is not performed between panels of the terminal, there is no need to perform power enhancement for a single panel, but power enhancement is performed on a terminal basis, wherein the number of layers of uplink PUSCH resources scheduled by the terminal is It is the sum of the number of layers of uplink PUSCH resources in the SRS resource sets corresponding to multiple panels in the terminal, that is, the sum of the number of layers of uplink PUSCH resources in the two SRS resource sets corresponding to the terminal.

[0274] For example, when determining the power boost factor of the terminal, at least the following two possible implementations may be included:

[0275] In a possible implementation, the terminal is configured to perform power boost and the high-level parameter UL-PTRS-power is configured. When the code point indicated by UL-PTRS-power is "00" and the number of layers of uplink PUSCH resources scheduled by the terminal is When the value is 1, the power enhancement factor of the terminal The value of is 0, regardless of the coherence type of the terminal, indicating that no power enhancement is performed.

[0276] When the code point indicated by UL-PTRS-power is "00", the number of layers of uplink PUSCH resources scheduled by the terminal is When the value is greater than 1, if the coherence type of the terminal is full coherence, the power enhancement factor of the terminal can be determined based on the mapping relationship between code points, coherence and the number of layers of channel transmission resources. The calculation formula is The terminal can be based on the formula Further calculate the power enhancement factor of the terminal Among them, the power enhancement factor of the terminal The calculation formula is determined based on the number of layers of channel transmission resources scheduled by the terminal.

[0277] When the code point indicated by UL-PTRS-power is "00", the number of layers of uplink PUSCH resources scheduled by the terminal is When the value is greater than 1, if the coherence type of the terminal is partial coherence, the power enhancement factor of the terminal can be determined based on the mapping relationship between code points, coherence and the number of layers of channel transmission resources. The calculation formula is 10log 10 (L x Q p ), the terminal can be based on the formula 10log 10 (L x Q p) to further calculate the power enhancement factor of the terminal Among them, the power enhancement factor of the terminal The calculation formula is determined based on the number of layers of channel transmission resources that can be coherently coded related to the PTRS port scheduled by the terminal and the number of PTRS ports scheduled by the terminal.

[0278] When the code point indicated by UL-PTRS-power is "00", the number of layers of uplink PUSCH resources scheduled by the terminal is When the value is greater than 1, if the coherence type of the terminal is incoherent, the PTRS ports between different layers cannot borrow power from each other, and can only borrow the power of the PTRS ports under different resource elements (RE) in the same layer. Based on the mapping relationship between the code point, coherence and the number of layers of channel transmission resources, the power enhancement factor of the terminal can be determined. The calculation formula is 10log 10 (Q p ), the terminal can be based on the formula 10log 10 (Q p ) to further calculate the power enhancement factor of the terminal Among them, the power enhancement factor of the terminal It is determined based on the number of PTRS ports scheduled by the terminal.

[0279] In another possible implementation, the terminal is configured to perform power boost and a high-level parameter UL-PTRS-power is configured. When the code point indicated by UL-PTRS-power is "00", the power boost factor of the terminal is The calculation formula is 10log 10 (L x Q p ), the terminal can be based on the formula 10log 10 (L x Q p ) to further calculate the power enhancement factor of the terminal The number of layers of uplink PUSCH resources scheduled for irrelevant terminals and the coherence type of the terminal. Among them, the power enhancement factor of the terminal The calculation formula is determined based on the number of layers of channel transmission resources that can be coherently coded related to the PTRS port scheduled by the terminal and the number of PTRS ports scheduled by the terminal.

[0280] It can be understood that in the above two possible implementations, L xIndicates the number of layers of PUSCH resources that can be coherently coded and are associated with PTRS ports in an antenna group, or indicates the number of layers of PUSCH resources that have the same number of demodulation reference signal (DMRS) ports that can be coherently coded and are associated with PTRS ports in an antenna group; Q p Indicates the number of PTRS ports scheduled by the terminal.

[0281] In the above two possible implementations, when the code point indicated by UL-PTRS-power is "01" and the number of layers of uplink PUSCH resources scheduled by the terminal is When the value is 1, the power enhancement factor of the terminal The value of is 0, which is irrelevant to the coherence type of the terminal, indicating that no power enhancement is performed. For STxMP transmission, when the code point indicated by UL-PTRS-power is "01", it means that the terminal always assumes that full power transmission can be performed. Based on the mapping relationship between the code point, coherence and the number of layers of channel transmission resources, the power enhancement coefficient of the terminal can be determined. The calculation formula is The terminal can be based on the formula Further calculate the power enhancement factor of the terminal Among them, the power enhancement factor of the terminal It is determined based on the number of layers of channel transmission resources scheduled by the terminal. When the code point indicated by UL-PTRS-power is "10" or "11", the power enhancement factor of the terminal The value is retained.

[0282] It should be noted that in the embodiment of the present application, for non-codebook (NCB) PUSCH transmission, its power enhancement factor is The value of and the power enhancement factor under Non-PUSCH transmission The value of is kept consistent, thereby determining the power enhancement factor of the terminal

For STxMP transmission, when the code point indicated by UL-PTRS-power is "01" and the number of layers of uplink PUSCH resources scheduled by the terminal is When the value is 2, 3 or 4, it means that the terminal always assumes that full power transmission can be performed.

[0344] It can be seen that in the above-mentioned embodiments 1 to 6, the terminal can search for the corresponding target power enhancement factor indication information from the pre-configured mapping relationship based on the number of layers of the channel transmission resources scheduled by the terminal, the code point and coherence of the high-level parameter UL-PTRS-power, and enhance the transmit power of the PTRS port of the terminal based on the target power enhancement factor indication information. In this way, the terminal is associated with the number of layers of the scheduled channel transmission resources, so that the terminal can accurately determine the power enhancement factor of the terminal based on the high-level configuration information, and enhance the transmit power of the PTRS port of the terminal based on the power enhancement factor of the terminal, thereby realizing the power enhancement configured by the network device for it, thereby effectively improving the power control efficiency and the stability of the communication system.

[0345] The above-mentioned embodiments 1 to 6 are combined to describe in detail a possible scenario in which, when the target object is a terminal, the power enhancement coefficient of the terminal is determined in units of the terminal, and based on the power enhancement coefficient of the terminal, the transmission power of the PTRS port of the terminal is enhanced. Below, the technical solution of another possible scenario will be described in detail in combination with specific embodiments 7 to 12, when the target object is an associated object associated with the PTRS port of the terminal, that is, the power enhancement coefficient of the associated object is determined in units of the associated object, and based on the power enhancement coefficient of the associated object, the transmission power of the PTRS port of the associated object is enhanced.

[0346] In another possible scenario, the target object is an associated object associated with the PTRS port of the terminal, that is, the power enhancement coefficient of the associated object is determined based on the associated object, and the transmission power of the PTRS port of the associated object is enhanced based on the power enhancement coefficient of the associated object.

[0347] It is understandable that in this possible scenario, considering that power can be borrowed between panels of the terminal, it is necessary to consider whether power can be borrowed from another panel in each combination of the number of layers and coherence. When the number of layers of configured PUSCH resources is greater than 1, since different PTRS ports correspond to different panels and are sent on different REs, power enhancement needs to consider the correspondence between the number of configured PTRS ports and panels. Therefore, when power enhancement is performed in units of panels, the number of layers of uplink PUSCH resources scheduled by the panel is It is the number of uplink PUSCH resource layers corresponding to the PTRS port in the panel, that is, the number of uplink PUSCH resource layers in the SRS resource combination associated with the PTRS port.

[0348] For example, for any antenna panel related to the SRS resource set, when determining the panel-based power enhancement factor of the antenna panel, at least the following two possible implementations may be included:

[0349] In one possible implementation, the panel is configured to perform power boosting, and the high-level parameter UL-PTRS-power is configured, and the transmission mode is the SDM mode under STxMP (high-level parameter multipanelScheme = SDMscheme). When the code point of the high-level parameter UL-PTRS-power is "00", and the number of layers of uplink PUSCH resources corresponding to the PTRS port in the panel is When the value is 1, since power can be borrowed between panels, the power enhancement factor based on the panel The calculation formula is 10log 10 (Q p ), the terminal can be based on the formula Further calculation of panel-based power enhancement factor Among them, the power enhancement factor based on the panel It is determined based on the number of PTRS ports on the panel.

[0350] When the code point indicated by the high-level parameter UL-PTRS-power is "00", the number of uplink PUSCH resources corresponding to the PTRS port in the panel When greater than 1, for any PTRS port, power can be borrowed from different layers. If the coherence type of the panel is full coherence, the power enhancement factor based on the panel can be determined based on the mapping relationship between code points, coherence, and the number of layers of channel transmission resources. The calculation formula is The terminal can be based on the formula Further calculation of panel-based power enhancement factor Among them, the power enhancement factor based on the panel The calculation formula is determined based on the number of layers of channel transmission resources scheduled by the panel.

[0351] When the code point indicated by UL-PTRS-power is "00", the number of uplink PUSCH resources corresponding to the PTRS port in the panel When greater than 1, if the coherence type of the panel is partial coherence, only the PTRS ports in the coherence group can borrow power. Based on the mapping relationship between code points, coherence, and the number of layers of channel transmission resources, the power enhancement factor based on the panel can be determined. The calculation formula is 10log 10 (L x Q p ), the terminal can be based on the formula 10log 10 (L x Q p ) Further calculate the power enhancement factor based on the panel Among them, the power enhancement factor based on the panel The calculation formula is based on the number of layers of channel transmission resources that can be coherently coded related to the PTRS port of the panel and the number of PTRS ports based on the panel.

[0352] When the code point indicated by the high-level parameter UL-PTRS-power is "00", the number of uplink PUSCH resources corresponding to the PTRS port in the panel When it is greater than 1, if the coherence type of the panel is incoherent, the PTRS ports in different layers cannot borrow power from each other, and can only borrow the power of the PTRS ports under different resource elements (RE) in the same layer. Based on the mapping relationship between the code point, coherence and the number of layers of channel transmission resources, the power enhancement factor based on the panel can be determined. The calculation formula is 10log 10 (Q p ), the terminal can be based on the formula 10log 10 (Q p ) Further calculate the power enhancement factor based on the panel Among them, the power enhancement factor based on the panel It is determined based on the number of PTRS ports on the panel.

[0353] In another possible implementation, the panel is configured to perform power boost and the higher-level parameter UL-PTRS-power is configured. When the code point indicated by the higher-level parameter UL-PTRS-power is "00", the power boost factor based on the panel The calculation formula is 10log 10 (L x Q p ), the terminal can be based on the formula 10log 10 (L x Q p ) Further calculate the power enhancement factor based on the panel The number of uplink PUSCH resource layers corresponding to the PTRS port in the panel is irrelevant And the coherence type of the panel. Among them, the power enhancement factor based on the panel The calculation formula is based on the number of layers of channel transmission resources that can be coherently coded related to the PTRS port of the panel and the number of PTRS ports based on the panel.

[0354] It can be understood that in the above two possible implementations, L x Indicates the number of layers of PUSCH resources that can be coherently coded and are associated with PTRS ports in an antenna group, or indicates the number of layers of PUSCH resources that have the same number of demodulation reference signal (DMRS) ports that can be coherently coded and are associated with PTRS ports in an antenna group; Q p Indicates the number of panel-based PTRS ports.

[0355] In the above two possible implementations, when the code point indicated by the high-level parameter UL-PTRS-power is "01" and the number of layers of uplink PUSCH resources corresponding to the PTRS port in the panel is When , the power enhancement factor based on the panel can be determined based on the mapping relationship between the code point, coherence and the number of layers of channel transmission resources. The calculation formula is The terminal can be based on the formula Further calculation of panel-based power enhancement factor Among them, the power enhancement factor based on the panel The calculation formula is based on the number of layers of channel transmission resources scheduled by the panel. For STxMP transmission, when the code point indicated by the high-level parameter UL-PTRS-power is "01", indicating that the panel always assumes that full power transmission is possible, the power enhancement factor based on the panel can be determined based on the mapping relationship between the code point, coherence and the number of layers of channel transmission resources. The calculation formula is The terminal can be based on the formula Further calculation of panel-based power enhancement factor Among them, the power enhancement factor based on the panel It is determined based on the number of layers of channel transmission resources scheduled by the panel. When the code point indicated by the high-level parameter UL-PTRS-power is "10" or "11", the power enhancement factor based on the panel The value is retained.

[0356] It should be noted that in the embodiment of the present application, for non-codebook (NCB) PUSCH transmission, its power enhancement factor is The value of and the power enhancement factor under Non-PUSCH transmission The value of is kept consistent, so as to determine the power enhancement factor based on the panel

For STxMP transmission, when the code point indicated by the high-level parameter UL-PTRS-power is "01" and the number of layers of uplink PUSCH resources scheduled by the panel is When the value is 2, 3 or 4, it means that the panel always assumes that full power transmission can be performed.
