Claim Text:
1. A method for performing radio access technology specific cell search, the method comprising: tuning a radio to a frequency and bandwidth to simultaneously accommodate a plurality of frequency channels of a plurality of radio access technologies, wherein each frequency channel of the plurality of frequency channels is associated with a candidate frequency of a radio access technology of the plurality of radio access technologies; acquiring a set of radio samples simultaneously acquired across the plurality of radio access technologies by the radio tuned to the frequency and bandwidth; performing a radio access technology specific frequency scan on the set of radio samples to detect candidate frequencies of each radio access technology of the plurality of access technologies; performing a radio access technology specific cell scan on each detected candidate frequency; determining whether sufficient memory exists in the radio to store radio samples of all possible frequency channels of all radio access technologies prior to completing the radio access technology specific cell scan on each detected candidate frequency; in response to determining that sufficient memory exists, retuning the radio and performing physical broadcast channel (PBCH) decoding for each detected candidate frequency using each associated radio access technology on each associated cell using the stored radio samples; and in response to determining that insufficient memory exists:
