- a switch can be set, and the user equipment can make a judgment after the TPC field can be used to indicate a non-TMC command.
- the user equipment determines, according to the notification from the network side, whether the TPC field of the first DCI format information is a non-TPC command after determining that the TPC domain can be used to indicate a non-TPC command.
- the user equipment determines, according to the PUCCH format configured by the network side, that the TPC domain can be used to indicate a non-TPC command.
- the user equipment may determine, according to the received network side notification message, the first DCI format information. Whether the TPC domain is a non-TPC command.
- the user equipment determines, according to the DAI in the first DCI format information, in step 501. Whether the TPC field of a DCI format information is a non-TPC command.
- FIG. 4 and FIG. 5 can synthesize a process to form a new method for performing power control, that is, first performing steps 401 to 403, and then performing steps 501 and 502.
- embodiments of the present invention can be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment, or a combination of software and hardware. Moreover, the present invention can be embodied in the form of a computer program product embodied on one or more computer-usable storage interfaces (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer usable program code.
- computer-usable storage interfaces including but not limited to disk storage, CD-ROM, optical storage, etc.
- the computer program instructions can also be stored in a computer readable memory that can direct a computer or other programmable data processing device to operate in a particular manner, such that the instructions stored in the computer readable memory produce an article of manufacture comprising the instruction device.
- the apparatus implements the functions specified in one or more blocks of a flow or a flow and/or block diagram of the flowchart.
- These computer program instructions can also be loaded onto a computer or other programmable data processing device such that a series of operational steps are performed on a computer or other programmable device to produce computer-implemented processing for execution on a computer or other programmable device.
- the instructions provide steps for implementing the functions specified in one or more of the flow or in a block or blocks of a flow diagram.
- the user equipment can determine the power control information provided by the network side and perform PUCCH power control, thereby improving the PUCCH power accuracy and the performance of the user equipment.
