Spectrum access system and access probe hybrid framework

A system comprising:

• a base station coupled to a network;
• a spectrum access system;
• a user equipment coupled to the base station and the spectrum access system, the user equipment comprising:
• a processor;
• and
• non-transitory computer readable media comprising instructions executable by the processor to:
• transmit a spectrum access request to the spectrum access system, wherein the spectrum access request includes a request for access to one or more frequency ranges of a spectrum;
• obtain, via the spectrum access system, a spectrum access response, wherein the spectrum access response is indicative that access to at least one of the one or more frequency ranges of the spectrum has been granted;
• in response to the spectrum access response, transmit a network access request to the base station;
• and
• establish, in response to the response granting access to the network has been received from the base station, a communication channel with the base station,
• wherein the network access request is transmitted at a power level exceeding a first power limit and up to a second power limit, and
• wherein a first access sequence includes increasing the power of one or more access request signals, wherein the instructions are further executable by the processor to:
• transmit a first access request signal of a first access sequence at a first power;
• and
• transmit each subsequent access request signal of the one or more access request signals at a subsequent power greater than a preceding power, and wherein the subsequent power does not exceed the first power limit.
