Communication device and method for controlling transceiver chains of a communication device
First Claim
1. A communication device comprising:
- a first transceiver chain set to communicate signals in a first frequency range;
a second transceiver chain set to communicate signals in a second frequency range distinct from the first frequency range, or set to no communication; and
a controller, configuredto receive an instruction for a resetting of carrier aggregation comprising a setting of the first transceiver chain or the second transceiver chain to communicate signals in a third frequency range different from the first frequency range and the second frequency range;
to control, in response to the reception of the instruction, the second transceiver chain to communicate signals within the first frequency range while the first transceiver chain simultaneously communicates signals within the first frequency range;
to control the first transceiver chain, when the communication of signals within the first frequency range by the second transceiver chain fulfills a predetermined criterion, to stop communication of signals within the first frequency range, and to communicate signals within the third frequency range;
wherein the predetermined criterion is the second transceiver chain providing at least one of valid I/O data from the reception of signals or data whose error rate is below a predetermined threshold from the reception of signals within the first frequency range.

Abstract
A communication device is described comprising a first transceiver chain set to communicate signals in a first frequency range, a second transceiver chain set to communicate signals in a second frequency range or set to no communication and a controller, configured to receive an instruction for a resetting of carrier aggregation comprising a setting of the first transceiver chain or the second transceiver chain to receive signals in a third frequency range different from the first frequency range and the second frequency range, to control, in response of the reception of the instruction, the second transceiver chain to receive signals within the first frequency range simultaneously with the first transceiver chain and to control the first transceiver chain, when the communication of signals within the first frequency range by the second transceiver chain fulfills a predetermined criterion, to stop communication of signals within the first frequency range.

14. A method for controlling transceiver chains of a communication device comprising:
-
setting a first transceiver chain to communicate signals in a first frequency range; setting a second transceiver chain to communicate signals in a second frequency range distinct from the first frequency range or to no communication; receiving an instruction for a resetting of carrier aggregation comprising a setting of the first transceiver chain or the second transceiver chain to communicate signals in a third frequency range different from the first frequency range and the second frequency range; controlling, in response of the reception of the instruction, the second transceiver chain to communicate signals within the first frequency range while the first transceiver chain simultaneously communicates signals within the first frequency range; controlling the first transceiver chain, when the communication of signals within the first frequency range by the second transceiver chain fulfills a predetermined criterion, to stop communication of signals within the first frequency range and to start communication of signals within a third frequency range; wherein the predetermined criterion is the second transceiver chain providing at least one of valid I/O data from the reception of signals or data whose error rate is below a predetermined threshold from the reception of signals within the first frequency range. - View Dependent Claims (15, 16, 17)
