Power saving mode for multi-carrier transmission

摘要

Methods and communication devices are described where in a first transmission mode a set of carriers having different carrier frequencies is used for payload data transmission, and in a second transmission mode at least some of the carriers of the set of carriers are refrained from being used, and the transmission power is reduced.

1. A method for multi-carrier data transmission, wherein carrier frequencies of each carrier of a set of carriers differ from one carrier to another, comprising:
using, in a first transmission mode, all carriers of the set of carriers for payload data transmission, and in a second transmission mode, refraining from transmitting payload data on at least one of the carriers of the set of carriers and reducing transmission power of the at least one of the carriers, using, in the first transmission mode, a further set of carriers different from the set of carriers and having different carrier frequencies for transmission of overhead data, and in the second transmission mode transmitting a load data via the further set of carriers which, in the first transmission mode, would be transmitted via the set of carriers.
