Abstract
An antenna switching method of an electronic device is provided. The antenna switching method includes measuring a transmit power variation of a first antenna, monitoring characteristics of received signals of both the first antenna and a second antenna, determining a comparison result by comparing the characteristics of the received signals of both the first antenna and the second antenna when the transmit power variation is greater than or equal to a threshold value, and switching a transmitting antenna based on at least the comparison result.
Claims21
An antenna switching method of an electronic device, the antenna switching method comprising:
- measuring a transmit power variation of a first antenna based on at least one of transmit power control (TPC) received from a base station and uplink scheduling information;
- monitoring characteristics of received signals of both the first antenna and a second antenna;
- determining a comparison result by comparing the characteristics of the received signals of both the first antenna and the second antenna when the transmit power variation is greater than or equal to a threshold value;
- and
- switching a transmitting antenna based on at least the comparison result,
- wherein after the measuring of the transmit power variation and the monitoring of characteristics of the received signals are performed for a first period, the method further comprising:
- monitoring the characteristics of the received signals of both the first antenna and the second antenna for a second period which is longer than the first period;
- and
- obtaining average values of the characteristics of the received signals monitored for the second period,
- wherein the switching of the transmitting antenna is performed further based on the comparison result and the average values of the characteristics of the received signal.
An electronic device comprising:
- a plurality of antennas configured to include an antenna functioning as a transmitting antenna;
- and
- at least one processor configured to:
- measure a transmit power variation of the transmitting antenna based on at least one of transmit power control (TPC) received from a base station and uplink scheduling information,
- monitor received signal characteristics of signals received by the plurality of antennas, and
- switch the transmitting antenna to another antenna based on a comparison result of a comparison of the received signal characteristics when a variation of the transmit power is greater than or equal to a threshold value,
- wherein after the measuring of the transmit power variation and the monitoring of characteristics of the received signals are performed for a first period, the at least one processor is further configured to:
- monitor the characteristics of the received signals of both the first antenna and the second antenna for a second period which is longer than the first period;
- and
- obtain average values of the characteristics of the received signals monitored for the second period,
- wherein the switching of the transmitting antenna is performed further based on the comparison result and the average values of the characteristics of the received signal.
