  • one category of IA users can be a fixed satellite station (FSS).
  • FSS can be a protected device.
  • An FSS can have a known geographical location and can be transmitting and receiving signals in a certain frequency band.
  • CBSDs There are two classes of CBSDs.
  • Category A can include a CBSD with a nominal maximum Equivalent Isotopically Radiated Power (EIRP) of 30 dBm/lOMHz.
  • EIRP Equivalent Isotopically Radiated Power
  • Category B can include a CBSD with a maximum EIRP of 47 dBm/lOMHz.
  • CBSD When the CBSD is located in the vicinity of an FSS, in order not to interfere with the FSS operation, CBSD may not be able to transmit at the nominal max power.
  • the SAS server can be responsible for calculating the max EIRP allowed per CBSD in a time window (Coordinated Periodic Activates among SASes sometimes known as a CPAS window) to ensure the combined signals from all CBSDs is below the maximum allowed interference level of the FSS, also known as the interference budget of FSS.

  • the SAS can deny the transmission request for the CBSD by setting the transmitExpireTime field to a value that will result in a timeout.

  • the first state can be transmitting when the transmitExpireTime has not expired.
  • the second state can be ceasing radio transmission after transmitExpireTime has expired.
  • An interference budget (e.g., the amount of permitted interference) for a given protected entity is equally split among all the interfering CBSDs.
  • This scheme does not promote development of high spectral efficiency features for the CBRS band, since the allowed interference is equally split independent of possible efforts of some operators to reduce interference towards the protected devices.
  • the CBSD(s) surrounding/neighbour CBSD(s) interfering with the protected device can equally benefit from this reduction in interference (e.g., by being allowed a higher transmission power without adopting interference reduction features).
  • a protected device e.g., WinnForum two-dimensional (2D) antenna patterns
  • the CBSD may cease transmissions in the channels that the CBSD cannot transmit below the requested EIRP. This can result in coverage outage for the channel where the max EIRP could not be met which may be an inefficient use of the interference budget from a CBRS operator point of view.
  • Example implementations include allocation of an interference budget to a plurality of CBSDs (e.g., an operator’s CBSDs) in a coverage area (e.g., interference area, in the vicinity) of a protected device.
  • Allocating the interference budget to a plurality of CBSDs can enable CBRS operators to fully exploit the gains generated by deploying features which aid in higher spectral efficiency and can enable CBSDs requested to transmit at an EIRP below the min capability to no longer have to cease transmissions because the CBSDs can be assigned a larger amount of the allocated interference budget to maintain a minimum desired level of capacity/coverage.
  • Example implementations can reduce processing demands on the SAS because the SAS may not have to compute all possible combinations for all existing CBSDs in the coverage area of the protected device, i.e., also trying to derive a solution which maximizes spectral efficiency and is fair to all CBSD operator’s accounting for each operators preferences.
  • Example implementations can enable an operator to trade off coverage/capacity requirements between their CBSDs (e.g., coverage can be restricted in certain cells to favour other cells).
