POWER SAVING MODE FOR MULTI-CARRIER TRANSMISSION
First Claim
Patent Images
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, andin 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.

Abstract
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.

13. A communication device for multi-carrier data transmission, comprising communication circuitry which is configured to use,
in a first transmission mode, a first set of carriers for payload data transmission, and, in a second transmission mode, a second set of carriers for payload data transmission, wherein the second set of carriers is a subset of the first set of carriers that does not comprise at least one of the carriers of the first set of carriers, wherein, in the second transmission mode, transmission power of the at least one carrier of the first set of carriers that is not comprised in the second set of carriers is reduced with respect to transmission power in the first transmission mode.

15. A method, comprising:
-
allocating, by a communication device, a set of carriers for use for communication of data; communicating data, in a first transmission mode, on all carriers associated with the set of carriers; and communicating data, in a second transmission mode, on less than all carriers associated with the set of carriers. - View Dependent Claims (16, 17, 18, 19, 20)
