Abstract

Provided are an information transmission method and device, which relate to the field of wireless communications and reduce the complexity of a base station conducting blind detection on power setting conditions of symbols of a subframe sent by a user equipment in dual-connection technology. The method comprises: determining transmitting power indication information about all the symbols in a first subframe, wherein the transmitting power indication information indicates at least one set in the first subframe, the set at least comprising one symbol, and the transmitting powers of all the symbols in the set are the same; and sending signalling carrying the transmitting power indication information to a base station to enable the base station to determine at least one set in the first subframe according to the transmitting power indication information.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an information transmission method and device. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) communication system, there is a CA (Carrier Aggregation, Carrier Aggregation) technology, that is, two or more component carriers can be aggregated together for data transmission to support larger bandwidth, these The aggregated component carriers can serve one user at the same time and send and receive data. [0003] In the CA system, since the propagation delays of signals arriving at the user equipment in different cells serving the user equipment are different, multiple cells serving the user equipment are divided into different TAGs according to the propagation delays of their signals reaching the user equipment (Timing Advance Group, Timing Advance Group). [0004] At present, the dual connectivity technology is introduced in the...
