Power determining method, user equipment, and base station

A user equipment, comprising:

• a processor, configured to acquire an initial transmit power of each transmission object in a transmission object set, and acquire a priority sequence of information corresponding to the transmission objects and a maximum transmit power, wherein the transmission object set comprises all to-be-transmitted uplink channels and/or sounding reference signals SRSs;
• when a sum of initial transmit powers of all the transmission objects in the transmission object set is greater than the maximum transmit power, perform a power reduction operation based on the priority sequence of the information corresponding to a transmission object, so as to acquire an available transmit power of each transmission object in the transmission object set, wherein a sum of available transmit powers of all the transmission objects in the transmission object set is not greater than the maximum transmit power;
• and
• a sender, configured to send each transmission object in the transmission object set according to the available transmit power that is acquired by the processor and is corresponding to each transmission object in the transmission object set;
• wherein the processor is configured to:
• acquire the priority sequence of the information corresponding to the transmission object, wherein the priority sequence of the information corresponding to the transmission object comprises a priority sequence of UCI carried in a transmission object;
• wherein the processor is configured to acquire the priority sequence of the UCI carried in the transmission object, wherein the priority sequence of the UCI carried in the transmission object comprises at least one of the following:
• when channel state information and a scheduling request exist, a priority of the channel state information is lower than a priority of the scheduling request;
• and
• when hybrid automatic repeat request information and a scheduling request exist, a priority of the hybrid automatic repeat request information is higher than or equal to a priority of the scheduling request
• wherein the processor is specifically configured to acquire the priority sequence of the UCI carried in the transmission object, wherein the priority sequence of the UCI carried in the transmission object comprises at least one of the following:
• when channel state information exists and the channel state information comprises a channel quality indicator and a precoding matrix, a priority of the channel quality indicator is equal to a priority of the precoding matrix;
• and
• when channel state information exists and the channel state information comprises a rank indicator, a channel quality indicator, and a precoding matrix, the rank indicator has a highest priority.
