Abstract
An apparatus for use in a mobile device includes a switch unit configured to switch a common connection of a transmitter and a first receiver from a first antenna to a second antenna and a connection of a respective second receiver from the second antenna to the first antenna; and a processing system configured to detect a switch condition that the transmitter needs to transmit via the second antenna, obtain power-related reception parameters of said first and said second receivers, cause the switch unit to switch the common connection of the transmitter and the first receiver so that the transmitter transmits via the second antenna, and adjust the power of the transmitter in dependence on the power-related reception parameters.
Claims20
An apparatus for use in a mobile device, the apparatus comprising:
- a switch unit configured to switch a common connection of a transmitter and a first receiver between a first antenna and a second antenna and a connection of a respective second receiver between the second antenna and the first antenna;
- and
- at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to:
- obtain a first power-related reception parameter of the first receiver receiving via the second antenna, and a second power-related reception parameter of the second receiver receiving via the first antenna;
- cause the switch unit to connect the common connection of the transmitter and the first receiver with the second antenna so that the transmitter transmits via the second antenna;
- and
- calculate a reduction in transmission power for the transmitter to transmit via the second antenna, corresponding to a ratio of the second power-related reception parameter to the first power-related reception parameter, a difference between the second power-related reception parameter and the first power-related reception parameter, or a combination thereof.
A method for use in a mobile device, the method comprising:
- switching a common connection of a transmitter and a first receiver between a first antenna and a second antenna and a connection of a respective second receiver between the second antenna and the first antenna by a switch unit;
- and
- processing comprising:
- obtaining a first power-related reception parameter of the first receiver receiving via the second antenna, and a second power-related reception parameter of the second receiver receiving via the first antenna;
- causing the switch unit to connect the common connection of the transmitter and the first receiver with the second antenna so that the transmitter transmits via the second antenna;
- and
- calculating a reduction in transmission power for the transmitter to transmit via the second antenna, corresponding to a ratio of the second power-related reception parameter to the first power-related reception parameter, a difference between the second power-related reception parameter and the first power-related reception parameter, or a combination thereof.
