Embodiment 1

[0035] figure 1 It is a schematic diagram of a power control method provided by an embodiment of the present invention. like figure 1 As shown, the method includes the following steps:

[0036] 101. The base station generates indication information, where the indication information is used to indicate the state of the power correction amount f(i) of the physical uplink shared channel PUSCH and the state of the power correction amount g(i) of the physical uplink control channel PUCCH of the user equipment UE.

[0037] In this embodiment, the base station generates indication information. Wherein, the indication information may indicate the status of the UE configuring the power correction amount f(i) of the PUSCH and the state of the power correction amount g(i) of the physical uplink control channel PUCCH.

[0038] Optionally, the base station may generate indication information including the first identification code and the second identification code. Wherein, the first ...

Embodiment 2

[0055] figure 2 It is a schematic diagram of another power control method provided by an embodiment of the present invention. like figure 2 As shown, the method includes:

[0056] 201. The user equipment UE receives indication information sent by the base station, where the indication information is used to indicate the state of the power correction amount f(i) of the physical uplink shared channel PUSCH and the power correction amount g(i) of the physical uplink control channel PUCCH of the UE i) status.

[0057] In this embodiment, the base station generates indication information. Wherein, the indication information may indicate the status of the UE configuring the power correction amount f(i) of the PUSCH and the state of the power correction amount g(i) of the physical uplink control channel PUCCH.

[0058] After generating the indication information, the base station sends the indication information to the UE. In this embodiment, for the process of the base statio...

Embodiment 3

[0069] image 3 It is a schematic structural diagram of a base station provided by an embodiment of the present invention. like image 3 As shown, the base station includes: a generating module 31 and a sending module 32 .

[0070] The generating module 31 is used for generating an instruction message. Wherein, the indication information is used to instruct the UE to configure the state of the power correction amount f(i) of the PUSCH and the state of the power correction amount g(i) of the physical uplink control channel PUCCH.

[0071]Optionally, the generation module 31 may generate indication information including the first identification code and the second identification code. Wherein, the first identification code is used to indicate the status of f(i), and the second identification code is used to indicate the status of g(i). For example, the first identification code and the second identification code are respectively one bit. The value of each bit can be "1" or ...

Abstract

Provided are a power control method and device. The method comprises: a base station sending indication information to a UE, the UE configuring a state of power correction amount f(i) of a PUSCH and a state of power correction amount g(i) of a PUCCH according to the indication information, and the UE controlling transmission power of the UE according to the configured f(i) and g(i). The base station in the present embodiments can send the indication information to the UE to indicate the UE to configure the states of f(i) and g(i). For a UE where false detection easily occurs, the base station can issue indication information which indicates that the states of f(i) and g(i) are disabled, so that the problem that there is a relatively large error between the transmission power of the UE and a target value due to the false detection of the UE can be avoided, and the accuracy of the transmission power of the UE can be improved, thereby improving the performance of the UE.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a power control method and device. Background technique [0002] In the Long Term Evolution (LTE) system, the user equipment (UserEquipment, UE) continuously obtains the power control command word sent by the base station to obtain the power correction value f(i) of the Physical Uplink Shared Channel (PUSCH) and the physical uplink The power correction amount g(i) of the control channel (PhysicalUplinkControlChannel, PUCCH). Then use f(i) and g(i) to adjust the transmission power of PUSCH and PUCCH. [0003] Currently, existing UEs always configure the states of f(i) and g(i) to be enabled. However, in practice, some UEs are in a scenario where misdetection or misdetection of the power control command word is prone to occur. In this scenario, after the UE misdetects or misdetects the power control command word, f(i) or g (i) An error occurs, resulting in ...
