1. A method for power adjustment in a user equipment (UE), comprising:
receiving first information from a base station, wherein:
the first information is used to trigger a first operation, the first operation including an accumulation reset corresponding to a first power value;
receiving K piece(s) of target information from the base station, wherein:
the K piece(s) of target information is(are) received by the UE after triggering of the first operation; and the K is a positive integer;
transmitting 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 received by the UE prior to triggering the accumulation reset; a sum of K power offset value(s) is used by the UE 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 P antenna port groups, P is an integer larger than 1; 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; the first antenna port group is any one of the P antenna port groups.
