Title | Method And Device In Ue And Base Station Used For Power Adjustment |

Inventorship | Xiaobo Zhang, Shanghai (CN) |

Assignee | SHANGHAI LANGBO COMMUNICATION TECHNOLOGY COMPANY LIMITED, Shanghai (CN) |

1. A method in a User Equipment (UE) for power adjustment, comprising:receiving L reference signal groups;

receiving R first signaling(s); and

transmitting a first radio signal;

wherein the L reference signal groups are transmitted by L antenna port sets respectively, the R first signaling(s) is (are) used for determining R first offset(s), the first radio signal comprises a first report, the first report is used for determining K difference value(s), the K difference value(s) respectively corresponds(correspond) to K first reference power value(s); each of the K first reference power value(s) is linearly correlated to a sum of the R first offset(s); measurement(s) on K reference signal group(s) is (are) respectively used for determining the K first reference power value(s), the K reference signal group(s) is (are) a subset of the L reference signal groups; a transmitting power of the first radio signal is a first power; the first power is associated with a first reference signal group; the first reference signal group is one of the K reference signal group(s); the R first offset(s) is (are) used for determining the first power; an antenna port set comprises a positive integer number of antenna port(s); all antenna ports of the L antenna port sets are used for one same serving cell, or all antenna ports of the L antenna port sets are used for one same carrier; the L is a positive integer greater than 1, the K is a positive integer not greater than the L, the R is a positive integer.
