Method and device for power adjustment in UE and base station

A method for power adjustment in a base station, comprising:

• transmitting first information, wherein:
• the first information is used to trigger a first operation, the first operation including an accumulation reset corresponding to a first power value;
• transmitting K piece(s) of target information, wherein:
• the K piece(s) of target information is(are) received after triggering of the first operation;
• and the K is a positive integer;
• receiving a first wireless signal;
• wherein, the transmission power value of the first wireless signal is the first power value;
• the first power value is irrelevant to all piece(s) of target information prior to triggering the accumulation reset;
• a sum of K power offset value(s) is used to calculate the first power value;
• the K power offset value(s) is(are) respectively indicated by the K piece(s) of target information;
• the first information is used to determine one antenna port group;
• the first power value is associated with a first antenna port group;
• the antenna port group comprises at least one antenna port;
• the K is a positive integer;
• the first power value is calculated based on a measurement of the first antenna port group;
• the target information is a Transmitting Power Control field, the first information is a Radio Resource Control layer signaling;
• a Reference Signal transmitted by the antenna port is a Channel State Information Reference Signal.

A user equipment (UE) for power adjustment, comprising:
