Abstract:
1. A method in a network node for controlling thermal energy generation in a first mobile transceiver operating in a radio telecommunication network, wherein said thermal energy generation is directly proportional to a transmit power level in the first mobile transceiver, and the network node allocates transmit power levels to a plurality of mobile transceivers through Serving Grants, said method comprising the steps of: receiving from the first mobile transceiver, Scheduling Information and an indication that the first mobile transceiver is not satisfied with a first Serving Grant; in response to receiving the indication from the first mobile transceiver, allocating only to the first mobile transceiver, a dedicated grant authorizing a transmit power level higher than the first Serving Grant; allocating to the plurality of mobile transceivers, a second Serving Grant reducing the transmit power level authorized for each of the mobile transceivers by an amount calculated to offset, when applied to the plurality of mobile transceivers, the dedicated grant allocated to the first mobile transceiver; subsequently receiving from the first mobile transceiver, a request to reduce transmit power due to an overheat condition in the first mobile transceiver; in response to receiving the request from the first mobile transceiver to reduce transmit power, removing the dedicated grant or a portion thereof from the first mobile transceiver; and allocating to the plurality of mobile transceivers, a third Serving Grant increasing the transmit power level authorized for each of the mobile transceivers by an amount calculated to offset, when applied to the plurality of mobile transceivers, the dedicated grant or the portion thereof removed from the first mobile transceiver.
