Patent Application
20250039803
This application pertains to the field of communication technologies, and in particular, to a transmit power determining method and apparatus, a terminal, a network side device, and a storage medium.
In the mobile communication system, transmission modes of uplink and downlink data usually include Frequency Division Duplex (FDD), Time Division Duplex (TDD), Half duplex (HD), Full Duplex (FD), and the like. For a symmetric spectrum of FDD, an uplink spectrum or a downlink spectrum of FDD may be semi-statically configured or dynamically indicated as downlink transmission or uplink transmission on some slots/symbols; for an asymmetric spectrum of TDD, different frequency domain resources of TDD on some slots/symbols may be semi-statically configured or dynamically indicated as both uplink transmission and downlink transmission; for a device of HD, only uplink sending or downlink reception can be performed at the same time, that is, the device cannot receive and send signals at the same time; and for a device of FD, the device may use same frequency band transmission for uplink sending or downlink reception at the same time.
At present, in the New radio (NR) system, when a base station operates in an FD mode, there is a case in which downlink data is sent to a 1st terminal on a frequency domain resource of a time t, and uplink data sent by a 2nd terminal is received at the same time.
However, when receiving the uplink data sent by the 2nd terminal, the base station may be affected by the downlink data sent by the base station to the 1st terminal. This effect may be usually offset by increasing a transmit power of the terminal for uplink transmission. However, there is no specific technical solution to determine the transmit power of the terminal for uplink transmission, resulting in low uplink transmission performance between the base station and the terminal.

It should be noted that, in the embodiments of this application, only a core network device in an NR system is used as an example for description, and a specific type of the core network device is not limited.
At present, in the NR system, when operating in an FD mode, a base station may be affected by downlink data sent by the base station to a 1st terminal in a case of receiving uplink data sent by a 2nd terminal. This effect may be usually offset by increasing a transmit power of the terminal for uplink transmission. However, in the current NR system, interference caused by a co-channel and/or an adjacent channel is not considered, and the transmit power required for uplink transmission cannot be determined based on a transmission format, such as a transmission format of uplink (UL), downlink (DL), or flexible, resulting in low uplink transmission performance between the base station and the terminal.
With reference to the accompanying drawings, a transmit power determining method provided in the embodiments of this application is described in detail by using some embodiments and application scenarios thereof.
The transmit power determining method provided in the embodiments of this application may be applied to a terminal 11, so that the terminal determines a transmit power for performing uplink transmission on a target uplink resource.
Step 201: A terminal receives L pieces of configuration information sent by a network side device, where the L pieces of configuration information include first power control configuration information and/or at least one piece of second power control configuration information; L is greater than or equal to 1; the first power control configuration information is used to determine a transmit power of the terminal for performing uplink transmission on a first uplink resource; and each piece of the second power control configuration information is used to determine a transmit power of the terminal for performing uplink transmission on a second uplink resource.
Step 202: The terminal determines, based on the L pieces of configuration information, a transmit power for performing uplink transmission on a target uplink resource.
It should be noted that this embodiment of this application may be applied to a terminal. When performing uplink transmission with a network side device such as a base station, the terminal may be interfered by downlink transmission between the network side device and other terminals. In this case, the network side device may indicate the terminal to increase the transmit power for uplink transmission, to reduce the above interference.
In this embodiment of this application, the terminal receives L pieces of configuration information sent by the network side device, where the configuration information includes first power control configuration information used to determine a transmit power of the terminal for performing uplink transmission on a first uplink resource and/or at least one piece of second power control configuration information used to determine a transmit power of the terminal for performing uplink transmission on a second uplink resource. Then the terminal may determine, based on the configuration information, the transmit power for uplink transmission on the target uplink resource. The terminal receives different power control configuration information configured by the network side device for the first uplink resource and the second uplink resource, so that the transmit power suitable for performing uplink transmission on the target uplink resource may be determined based on the different power control configuration information, thereby effectively improving uplink transmission performance between the network side device and the terminal.
In some embodiments, the terminal receives Radio Resource Control (RRC) signaling sent by the network side device, where the RRC signaling includes the L pieces of configuration information.
In some embodiments, the first uplink resource and the second uplink resource may be any one of the following resources:
The uplink transmission channel is, for example, a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH), and the uplink transmission signal is, for example, a Sounding Reference Signal (SRS).
In some embodiments, the first uplink resource has no co-channel interference and/or adjacent channel interference, and the second uplink resource has co-channel interference and/or adjacent channel interference.
For example, based on the L pieces of configuration information, the terminal may determine, in a case that the target uplink resource belongs to the first uplink resource, that the transmit power for uplink transmission on the target uplink resource is P1; and in a case that the target uplink resource belongs to the second uplink resource, it is determined that the transmit power for uplink transmission on the target uplink resource is P2. Because the terminal needs to increase the transmit power for uplink transmission, to reduce the co-channel interference and/or the adjacent channel interference, it may be set that P2>P1.
In some embodiments, a frequency domain resource unit of the first uplink resource satisfies at least one of the following:
Specifically, the frequency domain resource unit in a transmission format of DL or flexible may belong to a current cell or other cells, such as neighboring cells. To be specific, the considered co-channel interference and/or adjacent channel interference may be intra-cell or inter-cell.
In some embodiments, the transmission format includes a frequency domain transmission format or a time domain transmission format.
It should be noted that the frequency domain resource unit in a transmission format of DL is used to transmit downlink data; a frequency domain resource unit in a transmission format of flexible may be rewritten as a frequency domain resource unit in a transmission format of UL or DL, and in a case of being rewritten as a frequency domain resource unit in a transmission format of UL, the frequency domain resource unit is used to transmit uplink data; and in a case of being rewritten as a frequency domain resource unit in a transmission format of DL, the frequency domain resource unit is used to transmit downlink data.
The frequency domain resource unit includes at least one of the following:
In some embodiments, a frequency domain resource unit of the second uplink resource satisfies at least one of the following:
Specifically, the frequency domain resource unit in a transmission format of DL or flexible may belong to a current cell or other cells, such as neighboring cells. To be specific, the considered co-channel interference and/or adjacent channel interference may be intra-cell or inter-cell.
In some embodiments, the second power control configuration information is related to at least one of the following:
In some embodiments, different second power control configuration information corresponds to different degrees of co-channel interference and/or adjacent channel interference existing in the second uplink resource; and different second power control configuration information is used to determine different transmit powers.
For example,
Frequency domain sub-band 3 and frequency domain sub-band 4 are frequency domain resource units in a transmission format of DL, frequency domain sub-band 1 and frequency domain sub-band 2 are frequency domain resource units in a transmission format of UL, and frequency domain sub-band 1 and frequency domain sub-band 2 are provided with a PUSCH.
It can be seen from the figure that frequency domain sub-band 1 and frequency domain sub-band 2 are configured to be adjacent, frequency domain sub-band 2 and frequency domain sub-band 3 are configured to be adjacent, and frequency domain sub-band 3 and frequency domain sub-band 4 are configured to be adjacent. Compared with a frequency domain interval between frequency domain sub-band 1 and frequency domain sub-band 3, a frequency domain interval between frequency domain sub-band 2 and frequency domain sub-band 3 is smaller, so it can be considered that frequency domain sub-band 2 suffers more adjacent channel interference than frequency domain sub-band 1. In this case, frequency domain sub-band 2 may be configured to correspond to one second power control configuration information, and frequency domain sub-band 1 is configured to correspond to another second power control configuration information. Some parameters of these two pieces of second power control configuration information may be the same, and some parameters thereof may be different, for example, a transmit power included in the second power control configuration information corresponding to frequency domain sub-band 2 may be greater than a transmit power included in the second power control configuration information corresponding to frequency domain sub-band 1.
In addition, adjacent channel interference that frequency domain sub-band 1 and frequency domain sub-band 2 separately suffers may also be compared in another manner. In
In some embodiments, the configuration information includes at least one of the following power control parameters.
In some embodiments, a target transmit power included in the first power control configuration information may be smaller than a target transmit power included in the second power control configuration information.
In some embodiments, target transmit powers included in all second power control configuration information may be the same or different, and different target transmit powers are used to determine different co-channel interference and/or adjacent channel interference suffered by uplink transmission on different resources.
In some embodiments, different target transmit powers may be determined based on indicators related to co-channel interference and/or adjacent channel interference.
The indicators related to co-channel interference and/or adjacent channel interference are, for example, in-band emission, out of band emission, Adjacent Channel Selectivity (ACS) of a receiver, an Adjacent Channel Leakage Power Ratio (ACLR) of a transmitter, a frequency domain interval (NfreqGap) from a frequency domain resource unit in a transmission format of DL, and a frequency domain resource that is outside a frequency band for sending a signal and that is with a bandwidth of *U %.
Specifically, Alpha is used to compensate for losses such as path loss by increasing a power, and Alpha is usually set between 0 and 1.
In some embodiments, Alpha included in the first power control configuration information may be smaller than Alpha included in the second power control configuration information.
In some embodiments, Alpha included in all second power control configuration information may be the same or different, and different Alpha is used to determine different co-channel interference and/or adjacent channel interference suffered by uplink transmission on different resources.
In some embodiments, Pathloss parameter includes a pathloss RS and a reference signal power.
In some embodiments, Pathloss parameter included in the first power control configuration information may be a pathloss RS transmitted on a resource without co-channel interference or adjacent channel interference; and Pathloss parameter included in the second power control configuration information may be a pathloss RS transmitted on a resource with co-channel interference or adjacent channel interference.
In some embodiments, different pathloss RSs and reference signal powers may be configured based on a resource location or an interference magnitude of existing co-channel interference or adjacent channel interference.
In some embodiments, Power control loop included in the first power control configuration information may be the same as or different from Power control loop included in the second power control configuration information.
In some embodiments, TPC command included in the first power control configuration information may be the same as or different from TPC command included in the second power control configuration information.
In some embodiments, the power control offset is used to compensate for possible co-channel interference or adjacent channel interference.
It should be noted that power control parameter (1) to power control parameter (3) may be used for open-loop power control subsequently, and power control parameter (4) and power control parameter (5) may be used for closed-loop power control subsequently.
In some embodiments, the above power control parameters may be arbitrarily combined to form a power control parameter set, and the power control configuration information may include one or more power control parameter sets.
For example, power control configuration 1 includes 4 power control parameter sets, and each power control parameter set includes {P0, Alpha}; and power control configuration 2 includes 3 power control parameter sets, and each power control parameter set includes {P0, Alpha, pathloss}.
In some embodiments, the uplink transmission includes at least one of the following.
In some embodiments, the periodic uplink transmission or the semi-persistent uplink transmission is, for example:
In some embodiments, the dynamically scheduled uplink transmission is, for example, a PUSCH or a PUCCH scheduled by a network.
In some embodiments, in a case that the uplink transmission is repeated transmission, the terminal performs any one of the following operations:
In this embodiment of this application, the terminal receives different power control configuration information configured by the network side device for the first uplink resource and the second uplink resource, where the first uplink resource has no co-channel interference and/or adjacent channel interference, and the second uplink resource has co-channel interference and/or adjacent channel interference. On the basis of considering the co-channel interference and/or the adjacent channel interference, the terminal may determine transmit power suitable for performing uplink transmission on the target uplink resource based on the different power control configuration information, thereby effectively improving uplink transmission performance between the network side device and the terminal.

When the terminal needs to send uplink data on a PUSCH of frequency domain sub-band 1, the terminal determines, based on the first power control configuration information, that the transmit power for uplink transmission is P1.
Specifically, when the terminal needs to send uplink data on a PUSCH of frequency domain sub-band 1, because a frequency domain interval between frequency domain sub-band 1 and nearest frequency domain sub-band 3 in a transmission format of DL is 1 frequency domain sub-band, it can be considered that effect of adjacent channel interference is small, and the terminal may determine the transmit power for uplink transmission based on the first power control configuration information without considering the adjacent channel interference.
When the terminal needs to send uplink data on a PUSCH of frequency domain sub-band 2, the terminal determines, based on the second power control configuration information, that the transmit power for uplink transmission is P2.
Specifically, when the terminal needs to send uplink data on a PUSCH of frequency domain sub-band 2, because frequency domain sub-band 2 is adjacent to nearest frequency domain sub-band 3 in a transmission format of DL, it can be considered that effect of adjacent channel interference is great, and the terminal may determine the transmit power for uplink transmission based on the second power control configuration information. In this case, the adjacent channel interference needs to be considered.
In some embodiments, it is set that P2>P1 to improve performance of uplink transmission by increasing a transmit power of an uplink channel.
When the terminal needs to send uplink data on both a PUSCH of frequency domain sub-band 1 and a PUSCH of frequency domain sub-band 2, the terminal may perform any one of the following operations:
