Transmitting/receiving device and method for transmitting data in a radio network

摘要

In certain embodiments, an apparatus includes circuitry coupled to a switch between a first and second antenna of a device. The circuitry generates a first control signal for the switch to couple a transceiver of the device to the first antenna for transmission of a first data frame. The circuitry determines whether the transceiver has received, within a pre-determined time interval after transmission of the first data frame, a second data frame containing an acknowledgement message confirming successful receipt of the first data frame by another device. The circuitry generates, if the transceiver has not received the second data frame within the pre-determined time interval, a second control signal for the switch to couple the transceiver to the second antenna for re-transmission of the first data frame. An output line of the apparatus couples the circuitry to the switch and communicates the first or second control signal to the switch.

主权项

1. An apparatus comprising:
circuitry coupled to a switch between a first antenna of a device and a second antenna of the device, the switch being configured to couple a transceiver of the device to the first antenna or the second antenna, the circuitry being configured to: generate a first control signal for the switch to couple the transceiver to the first antenna for transmission of a first data frame by the transceiver via the first antenna; determine whether the transceiver has received, within a pre-determined time interval after the transmission of the first data frame, a second data frame containing an acknowledgement message confirming successful receipt of the first data frame by another device; and generate, if the transceiver has not received within the pre-determined time interval after the transmission of the first data frame the second data frame, a second control signal for the switch to couple the transceiver to the second antenna for retransmission of the first data frame by the transceiver via the second antenna; and an output line coupling the circuitry to the switch and being configured to communicate the first or second control signal to the switch.
