Abstract

An electronic device may include wireless circuitry with first and second receivers. Each receiver may include circuitry for receiving radio-frequency signals using a first radio access technology (RAT) and using second or additional RATs. The wireless circuitry may perform system selection in which the receivers attempt to acquire a signal transmitted by a base station using different RATs. The first receiver and the second receiver may concurrently perform system selection in which the first receiver performs a band scan over the first RAT while the second receiver concurrently performs a band scan over a second or additional RAT. Additional band scans may be performed as needed until a signal is acquired. Once a signal is acquired, the wireless circuitry may establish cellular communications with the wireless base station based on the acquired signal. This may minimize the amount of time required to begin cellular telephone communications in many situations.

Dependent claims

Wireless circuitry comprising:

a first receiver configured to communicatively couple with one or more antennas, the first receiver being configured to perform a first band scan of a first radio access technology (RAT) using the one or more antennas;
and
a second receiver configured to communicatively couple with the one or more antennas, the second receiver being configured to perform a second band scan of a second RAT using the one or more antennas concurrent with the first receiver performing the first band scan of the first RAT, wherein
the first receiver is configured to perform a third band scan of the second RAT after the first receiver has completed the first band scan and the second receiver has completed the second band scan,
the second receiver is configured to perform a fourth band scan of the first RAT concurrent with the first receiver performing the third band scan of the second RAT, and
the first receiver is configured to acquire a signal of the first RAT that was previously found by the second receiver during the fourth band scan of the first RAT.
