Methods and apparatus for transmission power management of citizens broadband radio service devices

A Citizens Broadband Radio Service Device (CBSD) comprising:

• one or more processors that operate the CBSD to:
• receive from a Spectrum Access System (SAS), at the CBSD, one or more of:
• i) a power headroom threshold value used to identify cell edge user equipment devices (UEs) or ii) a channel quality indicator threshold value used to identify cell edge user equipment devices (UEs);
• and
• receive a power down command from the SAS;
• identify based on one or more of the received power headroom threshold value and the received channel quality indicator threshold value cell edge UEs being serviced by the CBSD;
• decrease transmit power of the CBSD by an estimated amount of transmit power required to support the identified cell edge UEs;
• and
• receive from the SAS at least one of:
• a minimum time duration for statistics calculations with regard to a UE or a minimum number of samples to be used for statistics calculations with regard to the UE.

A non-transitory computer readable medium including a first set of computer executable instructions which when executed by a processor of a Citizens Broadband Radio Service Device (CBSD) cause the CBSD to:

• receive from a Spectrum Access System (SAS), at the CBSD, one or more of:
• i) a power headroom threshold value used to identify cell edge user equipment devices (UEs) or ii) a channel quality indicator threshold value used to identify cell edge user equipment devices (UEs);
• and
• receive a power down command from the SAS;
• identify based on one or more of the received power headroom threshold value and the received channel quality indicator threshold value cell edge UEs being serviced by the CBSD;
• decrease transmit power of the CBSD by an estimated amount of transmit power required to support the identified cell edge UEs;
• and
• receive from the SAS at least one of:
• a minimum time duration for statistics calculations with regard to a UE or a minimum number of samples to be used for statistics calculations with regard to the UE.
