Abstract
An electronic device is provided. The electronic device includes a plurality of antennas, a radio frequency (RF) circuit configured to electrically connect with the plurality of antennas, and a processor. The plurality of antennas include a first main antenna, a first sub-antenna, a second main antenna, and a second sub-antenna. The processor controls the RF circuit to operate in a first mode of receiving a signal using the first main antenna and the first sub-antenna. The processor controls the RF circuit to operate in a second mode different from the first mode to receive the signal based on a signal state.
Claims17
A chipset for a portable communication device, comprising:
- at least one processor configured to:
- control a radio frequency (RF) circuit of the portable communication device to receive a signal corresponding to a specified frequency band using a first set of one or more antennas selected from a plurality of antennas of the portable communication device;
- determine control information associated with data received via the signal for a specified period of time using the first set of one or more antennas;
- and
- control the RF circuit to receive the signal using a second set of one or more antennas selected from the plurality of antennas if the control information satisfies a specified condition, the second set of one or more antennas including at least one antenna not included in the first set of one or more antennas.
A chipset for a portable communication device, comprising:
- at least one processor configured to:
- perform a voice over long-term evolution (VoLTE) call using a radio frequency (RF) circuit of the portable communication device;
- while performing the VoLTE call, determine a signal state associated with a parameter indicating signal strength or signal quality for a specified period of time;
- and
- control the RF circuit to receive a signal with a first set of one or more antennas selected from a plurality of antennas of the portable communication device or to receive the signal with a second set of one or more antennas selected from the plurality of antennas based at least in part on the signal state,
- wherein the second set of one or more antennas including at least one antenna not included in the first set of one or more antennas.
A chipset for a portable communication device comprising:
- at least one processor configured to:
- control a radio frequency (RF) circuit of the portable communication device to receive a signal corresponding to a specified frequency band using a first set of one or more antennas selected from a plurality of antennas of the portable communication device;
- determine whether a specified condition is satisfied with respect to a number of one or more downlink grants in downlink control information (DCI) associated with data received via the signal for a specified period of time using the first set of one or more antennas;
- and
- control the RF circuit to receive the signal using a second set of one or more antennas selected from the plurality of antennas if the number satisfies the specified condition, the second set of one or more antennas including at least one antenna not included in the first set of one or more antennas.
