The present disclosure relates to, but is not limited to, the field of wireless communication technologies, and in particular to a method and apparatus for configuring a power of a terminal, a communication device and a storage medium.
Vehicle to Everything (V2X) is a new generation of information and communication technologies that connect vehicles to everything. V2X can provide two communication interfaces, which are referred to as the Uu interface and the PC5 interface, respectively. In wireless communications, demands for operator-based spectrums are increasing, but actual spectrums that can be allocated for use are gradually decreasing. In V2X scenarios, for operators' existing licensed frequency bands, it is a major demand for the operators to concurrently transmit New Radio (NR) shared spectrum services and NR V2X services on shared spectrums. For terminals, it will be a common scenario to concurrently transmit NR services and NR Sidelink services on the same licensed frequency band.

In order to facilitate the understanding of those skilled in the art, embodiments of the present disclosure exemplify a plurality of implementations to clearly illustrate technical solutions of the embodiments of the present disclosure. In addition, those skilled in the art can understand that a plurality of embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together with methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related arts alone or in combination, which is not limited in the embodiments of the present disclosure.
In order to better understand the technical solution described in any embodiment of the present disclosure, an application scenario of the power configuration in the related art is illustrated first.
In a scenario embodiment, in a NR Sidelink configuration, a network configures, by means of configuration and pre-configuration methods, a power of a terminal in Sidelink through a Radio Resource Control (RRC) signaling (e.g., sl-TxPower), and the network configures, on a NR shared spectrum, the maximum power that the terminal in the cell can transmit by configuring the RRC signaling (e.g., p-max). However, when the terminal works on the shared spectrum and transmits a NR Sidelink service, there is a situation where sl-TxPower and p-max are inconsistent, and in this case, a terminal configuration needs to be clarified.
In addition, if the terminal concurrently transmits the NR service and the NR Sidelink service on the shared spectrum, it is necessary to constrain the terminal power according to specific multiplexing modes (that is, a Frequency Division Multiplexing (FDM) mode or a Time Division Multiplexing (TDM) mode) of these two services, so as to ensure that the terminal power is controlled within an appropriate range to avoid interference with other communication transmissions in the cell.
In the related arts, power configuration manners used by the terminal for the NR service and the NR Sidelink service are inconsistent, resulting in that after the terminal accesses the cell, there are two different power configuration signalings when the terminal performs the NR Sidelink service on the licensed frequency band, which easily causes confusion. In addition, if the terminal concurrently performs the NR service and the NR Sidelink service on the shared spectrum, the power configuration of the terminal is also unclear at present. The present invention clarifies the power configuration for the above two situations to prevent from configuring too high power for the terminal in the cell to cause interference to other communications in the cell, or configuring too low power for the terminal in the cell to cause the performance degradation and reduced network coverage.
As shown in
in step 21, a power parameter for the terminal to transmit a predetermined service is determined according to a working state of the terminal;
the predetermined service includes: a New Radio (NR) service and/or an NR Sidelink (SL) service, and the working state includes one of:
a first working state indicating a state in which the terminal transmits the NR SL service on a shared spectrum; or
a second working state indicating a state in which the terminal transmits the NR service and the NR SL service on the shared spectrum.
Here, the terminal involved in the present disclosure may be but is not limited to a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensor device and/or a medical device, etc.
The network device involved in the present disclosure may be an access device for the terminal to access a network. Here, the network device may be various types of base stations, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations. It should be noted that the network device in the present disclosure is not limited to the base station in the access network, but may also be a communication node in a core network, which is not limited here. For example, determination and/or configuration operations in the present disclosure may also be performed by a network device in the core network.
In an embodiment of the present disclosure, the terminal may transmit the NR service and/or the NR SL service on the same licensed frequency band. For example, the terminal may transmit the NR service on the Uu interface, and the terminal may transmit the NR SL service on the PC5 interface.
It should be noted that the second working state may indicate the state in which the terminal concurrently transmits the NR service and the NR SL service on the shared spectrum. Here, the concurrent transmission of the NR service and the NR SL service may be the transmission of the NR service and the NR SL service on the same licensed frequency band in a frequency division mode or in a time division mode.
In an embodiment of the present disclosure, the network device determines, according to the working state of the terminal, the power parameter for the terminal to transmit the predetermined service, and sends power configuration information to the terminal, the power configuration information indicates the power parameter. Once receiving the power configuration information, the terminal can perform the NR service and/or the NR SL service based on the power parameter. Here, the power parameter may be a parameter indicating the maximum transmission power.
In an embodiment of the present disclosure, the network device sends to the terminal indication information indicating the working state. After receiving the indication information, the terminal transmits the NR service and/or the NR SL service based on the working state indicated by the indication information. The network device determines, according to the working state indicated by the indication information, the power parameter for the terminal to transmit the predetermined service. Here, the network device may send to the terminal the indication information indicating the working state through an RRC message.
In an embodiment of the present disclosure, the network device receives the indication information indicating the working state sent by the terminal, and the network device determines, according to the working state indicated by the indication information, the power parameter for the terminal to transmit the predetermined service. Here, the network device may receive, through the RRC message, the indication information indicating the working state sent by the terminal.
In an embodiment of the present disclosure, before sending the power configuration information to the terminal, the network device will configure a first parameter for the terminal, and the first parameter is a power for the terminal to transmit the NR SL service; the network device also configures a second parameter for the terminal, and the second parameter is the maximum transmit power of the terminal when transmitting the NR service in the cell. Here, the first parameter may be sl-TxPower, and the second parameter may be p-max.
In an embodiment of the present disclosure, the working state of the terminal is determined. If the working state of the terminal is determined to be the first working state, a smaller parameter among the first parameter and the second parameter is determined to be the power parameter. For example, if the first parameter is greater than the second parameter, the second parameter is determined to be the power parameter; or, if the first parameter is less than the second parameter, the first parameter is determined to be the power parameter. After the power parameter is determined, the network device sends the power configuration information to the terminal, and the power configuration information indicates the power parameter. It should be noted that the first working state may be a state in which the terminal transmits the NR SL service on the shared spectrum without transmitting the NR service on this shared spectrum. Here, the terminal may perform a single-carrier NR SL service transmission on the shared spectrum.
In an embodiment of the present disclosure, the working state of the terminal is determined. If the working state of the terminal is determined to be the first working state, the power parameter is determined to be the first parameter. After the power parameter is determined, the network device sends the power configuration information to the terminal, and the power configuration information indicates the power parameter.
In an embodiment of the present disclosure, after receiving the power configuration information, the terminal ignores the first parameter and the second parameter.
In an embodiment of the present disclosure, the working state of the terminal is determined. If the working state of the terminal is determined to be the second working state, it is necessary to determine a mode in which the terminal transmits the NR service and the NR SL service. According to the determined mode in which the terminal transmits the NR service and the NR SL service, the power parameter for the terminal to transmit the predetermined service is determined. It should be noted that the terminal may transmit the NR service and the NR SL service in a Time Division Multiplexing (TDM) mode, and the terminal may also transmit the NR service and the NR SL service in an FDM mode.
In an embodiment of the present disclosure, if it is determined that the working state of the terminal is the second working state and it is determined that the terminal transmits the NR service and the NR SL service in the Time Division Multiplexing (TDM) mode, the power parameter for transmitting the NR service is determined to be the second parameter and/or the power parameter for transmitting the NR SL service is determined to be a smaller parameter among configured parameters.
In an embodiment of the present disclosure, if it is determined that the working state of the terminal is the second working state and it is determined that the terminal transmits the NR service and the NR SL service in the Frequency Division Multiplexing (FDM) mode, the power parameter for transmitting the NR service is determined to be a third parameter and/or the power parameter for transmitting the NR SL service is determined to be a fourth parameter, and the sum of the third parameter and the fourth parameter is less than the second parameter. Here, the third parameter may be PNR, the fourth parameter may be PNR_SL, and the second parameter may be p-max. It should be noted that in the present disclosure, “less than” has the meaning of “less than or equal to”. It should be noted that here, the terminal transmits the NR service and the NR SL service on different carrier frequencies of the shared spectrum, respectively within the same time.
In an embodiment of the present disclosure, before sending to the terminal the power configuration information for transmitting the predetermined service, the network device will configure a time-frequency domain resource for the terminal according to a service type indicated for the terminal to transmit, and the time-frequency domain resource includes a time domain resource and/or a frequency domain resource. For example, if the service type indicated for the terminal to transmit is the NR SL service, a first time-frequency domain resource will be configured for the terminal; or if the service type indicated for the terminal to transmit is the NR service and the NR SL service, a second time-frequency domain resource for the NR service and a third time-frequency domain resource for the NR SL service will be configured for the terminal. In this way, the working state of the terminal can be determined based on the time-frequency domain resource configured for the terminal. For example, if the time-frequency domain resource configured for the terminal is the first time-frequency domain resource, the working state of the terminal is determined to be the first working state; or, if the time-frequency domain resource configured for the terminal is the second time-frequency domain resource and the third time-frequency domain resource, the working state of the terminal is determined to be the second working state.
In embodiments of the present disclosure, the power parameter for the terminal to transmit the service is determined according to the working state of the terminal, the working state includes at least one of: the first working state indicating the state in which the terminal transmits the NR SL service on the shared spectrum; or the second working state indicating the state in which the terminal transmits the NR service and the NR SL service on the shared spectrum. In this way, since the power parameter for the terminal to transmit the service is determined according to the working state of the terminal, different power parameters can be configured for different working states, and the power parameters will be quite clear. Compared with a situation where the use of the power parameter is unclear when the terminal is in different working states, the power parameters used in different working states can be clarified for the terminal. As such, the interference between the signals can be reduced, and the transmission performance of the terminal and the network communication coverage capability can be improved.

Here, the first parameter may be sl-TxPower, and the second parameter may be p-max. It should be noted that after configuring the first parameter and the second parameter, the network device may send the first parameter and the second parameter to the terminal through an RRC message.
In an embodiment of the present disclosure, after receiving the power configuration information, the terminal ignores the first parameter and the second parameter.
In an embodiment of the present disclosure, the working state of the terminal is determined. If the working state of the terminal is determined to be the first working state, a smaller parameter among the first parameter and the second parameter is determined to be the power parameter.

In an embodiment of the present disclosure, the configured parameter includes at least one of:
Here, the first parameter may be sl-TxPower, the second parameter may be p-max, the third parameter may be PNR, and the fourth parameter may be PNR_SL.
For a specific implementation of the step 41, reference may be made to the description of the step 31, which will not be repeated here.
Here, in response to the terminal being in the first working state, the power parameter is determined to be the smaller parameter among the configured parameters. In this way, since the power parameter is the smaller parameter among the configured parameters, the power consumption can be saved and the endurance of the terminal can be improved.
Here, in response to the terminal being in the second working state and transmitting the NR service and the NR SL service in the Time Division Multiplexing (TDM) mode, the power parameter for transmitting the NR service is determined to be the second parameter and/or the power parameter for transmitting the NR SL service is determined to be the smaller parameter among the configured parameters. In this way, since the time division multiplexing mode is used for transmission, different power parameters can be flexibly selected, making the configuration of the power parameter more flexible.

In this way, since the frequency division multiplexing mode is used for transmission, it is ensured that the sum of the third parameter and the fourth parameter is less than the second parameter, so that the transmission power of the terminal does not exceed the maximum of the terminal power, thereby ensuring the reliability of the communication.

For example, if the time-frequency domain resource configured for the terminal is the first time-frequency domain resource, the working state of the terminal is determined to be the first working state; or, if the time-frequency domain resource configured for the terminal is the second time-frequency domain resource and the third time-frequency domain resource, the working state of the terminal is determined to be the second working state.
In an embodiment of the present disclosure, the terminal is in the first working state, and after receiving the power configuration information, the terminal transmits the NR SL service based on the power parameter indicated by the power configuration information.
In an embodiment of the present disclosure, the terminal is in the second working state, then after receiving the power configuration information, the terminal transmits the NR service and the NR SL service based on the power parameter indicated by the power configuration information. If the terminal transmits the NR service and the NR SL service in the Time Division Multiplexing (TDM) mode, the power parameter for transmitting the NR service is determined to be the second parameter and/or the power parameter for transmitting the NR SL service is determined to be the smaller parameter among the configured parameters. Alternatively, if the terminal transmits the NR service and the NR SL service in the Frequency Division Multiplexing (FDM) mode, the power parameter for transmitting the NR service is determined to be the third parameter and/or the power parameter for transmitting the NR SL service is determined to be the fourth parameter. The sum of the third parameter and the fourth parameter is less than the second parameter. It should be noted that the configured parameter, the third parameter and the fourth parameter have been described above, which will not be repeated here.
