Embodiment 1

[0059] See figure 1 , an embodiment of the present invention provides a power adjustment method, and the process of the power adjustment method can be described as follows:

[0060] S100: The base station acquires terminal information of terminals multiplexed on the PUCCH domain of a physical uplink control channel, where the terminal information is used to indicate the number of terminals multiplexed on the PUCCH domain and / or the movement speed of each terminal;

[0061] S200: The base station adjusts a power control parameter of the PUCCH domain based on the terminal information, where the power control parameter is used to determine the uplink power of each terminal multiplexed on the PUCCH domain.

[0062] In practical applications, according to the protocol, the PUCCH can transmit terminal information on all uplink subframes except special subframes. Generally speaking, PUCCH channel resources can be located at both ends of the system bandwidth. E.g, figure 2 is a sc...

Embodiment 2

[0117] See image 3 , based on the same inventive concept, an embodiment of the present invention also provides a power adjustment system 10 to which the above power adjustment method can be applied.

[0118] The power adjustment system 10 includes: a base station 20 and a terminal 30. The base station 20 is used to obtain terminal information of terminals multiplexed on the physical uplink control channel PUCCH domain, and the terminal information is used to indicate the number of terminals on the PUCCH domain and / or the velocity of motion of each terminal; and,

[0119] Adjusting the power control parameters of the PUCCH domain based on the terminal information, where the power control parameters are used to determine the uplink power of each terminal multiplexed on the PUCCH domain.

[0120] Optionally, the base station 20 is configured to: determine the terminal number state according to the number of terminals multiplexed on the PUCCH domain, and determine the terminal m...

Embodiment 3

[0136] A computer device is also provided in the embodiment of the present invention, please refer to Figure 4 As shown, the computer device includes a processor 401 and a memory 402, wherein the processor 401 is configured to implement the steps of the power adjustment method provided in the embodiment of the present invention when executing a computer program stored in the memory 402 .

[0137] Optionally, the processor 401 may specifically be a central processing unit, an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), may be one or more integrated circuits for controlling program execution, and may use a field programmable gate array ( The hardware circuit developed by Field Programmable Gate Array (FPGA) can be a baseband processor.

[0138] Optionally, the processor 401 may include at least one processing core.

[0139] Optionally, the electronic device further includes a memory 402, and the memory 402 may include a read only me...

Abstract

Provided are a power adjustment method and system for solving the technical problem that it is very difficult for a base station to separate different terminals on the same PUCCH domain. The method comprises: a base station acquiring terminal information about multiplexed terminals on a physical uplink control channel (PUCCH) domain, the terminal information being used for indicating the number of the multiplexed terminals on the PUCCH domain and / or a movement speed of each terminal; and the base station adjusting a power control parameter of the PUCCH domain based on the terminal information, the power control parameter being used for determining an uplink power of each terminal multiplexed on the PUCCH domain.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power adjustment method and system. Background technique [0002] The power control in the Long Term Evolution (LTE) system is divided into downlink power control and uplink power control according to the link direction. Basically, the interference to other users is reduced as much as possible, and the battery life of the terminal is prolonged. [0003] Uplink power control can be divided into various types according to different objects, such as channels or sounding reference signals, such as physical uplink control channel (Physical Uplink Control Channel, PUCCH) power control, physical uplink shared channel ( Physical Uplink Shared Channel (PUSCH) power control, Sounding Reference Signal (Sounding Reference Signal, SRS) power control, Physical Random Access Channel (Physical Random Access Channel, PRACH) power control, etc. Among them, PUCCH is that the user sends uplink ...
