Title:
USER EQUIPMENT FOR POWER ADJUSTMENT, AND METHOD AND DEVICE IN BASE STATION
Document Type and Number:
WIPO Patent Application WO/2018/130125
Kind Code:
A1
Abstract:
Disclosed are a user equipment for power adjustment, and a method and device in a base station. The UE receives L reference signal sets, receives R pieces of first signaling, and then sends a first radio signal. The L reference signal sets are respectively sent by L antenna port sets, the R pieces of first signaling are respectively used for determining R first offsets, the first radio signal is used for determining K differences, and the K differences have one-to-one correspondence with K first reference powers. The K first reference powers are all in linear correlation with the R first offsets. Measurement on the K reference signal sets is used for determining the K first reference powers. The transmit power of the first radio signal is a first power, which is correlated with a first reference signal set, and the first reference signal set is one of the K reference signal sets. All antenna ports in the L antenna port sets are used for a same serving cell, or a same carrier. The invention improves the performance of power control and reduces the overhead.
