Systems, apparatus, and methods for antenna selection |
| 摘要 |
This disclosure provides systems, methods, and apparatus for mobile transmit diversity. In one aspect, a wireless communication apparatus is provided. The wireless communication apparatus includes a transmit circuit configured to transmit wireless communications via either a first antenna or a second antenna. The wireless communication apparatus further includes a receive circuit configured to receive wireless communications using either the first antenna or the second antenna. The wireless communication apparatus further includes a controller configured to switch the transmit circuit and the receive circuit from transmitting and receiving wireless communications via the first antenna to transmit and receive wireless communications via the second antenna in response to detecting that a first receive power level of the first antenna is less than a second receive power level of the second antenna and a difference between the second receive power level and the first receive power level is greater than a threshold. |

1. A wireless communication apparatus, comprising:
a transmit circuit configured to transmit wireless communications via either a first antenna or a second antenna; a receive circuit configured to receive wireless communications using either the first antenna or the second antenna; and a controller configured to switch the transmit circuit and the receive circuit from transmitting and receiving wireless communications via the first antenna to transmitting and receiving wireless communications via the second antenna in response to detecting:
a first receive power level of the first antenna is less than a second receive power level of the second antenna;a difference between the second receive power level and the first receive power level is greater than a first threshold; andthe difference between the second receive power level and the first receive power level added to a difference between a second transmit power limit of the second antenna and a first transmit power limit of the first antenna is greater than a second threshold. |
