Abstract
An apparatus includes Radio Frequency (RF) circuitry and baseband circuitry. The RF circuitry is configured to receive strobe messages that are based on a system clock over a digital interface, and to communicate synchronously with the system clock based on the received strobe messages in accordance with a Radio Access Technology (RAT) that is selected from among multiple different RATs. The baseband circuitry is configured to generate the strobe messages, to delay the strobe messages by a delay that depends on the selected RAT, and to send the delayed strobe messages to the RF circuitry over the digital interface.

Apparatus, comprising:
- Radio Frequency (RF) circuitry, which is configured to receive strobe messages over a digital interface, the strobe messages being based on a system clock, to select a Radio Access Technology (RAT) from at least a first RAT supported by the apparatus and a second RAT supported by the apparatus, the second RAT being different from the first RAT, and to communicate synchronously with the system clock based on the received strobe messages in accordance with the selected RAT;
- and
- baseband circuitry, which is configured to generate the strobe messages, to delay the strobe messages by a first delay when the selected RAT comprises the first RAT, to delay the strobe messages by a second delay, different from the first delay, when the selected RAT comprises the second RAT, and to send the delayed strobe messages to the RF circuitry over the digital interface.
A method, comprising:
- using baseband circuitry, generating strobe messages based on a system clock;
- selecting a Radio Access Technology (RAT) from at least a first supported RAT and second supported RAT, the second RAT being different from the first RAT;
- delaying the strobe messages in the baseband circuitry by a first delay when the selected RAT comprises the first RAT, and delaying the strobe messages by a second delay, different from the first delay, when the selected RAT comprises the second RAT;
- sending the delayed strobe messages over a digital interface from the baseband circuitry to Radio Frequency (RF) circuitry;
- and
- at the RF circuitry, receiving the strobe messages over the digital interface, and communicating synchronously to the system clock based on the received strobe messages in accordance with the selected RAT.
