Abstract
The technology is directed to a system that allocates a frequency band to a satellite within a non-terrestrial network (NTN) and determines the available channel bandwidth for data transmissions within that frequency band. If the satellite detects an absence of a Radio Resource Control (RRC) connection between the satellite and at least one terminal device within the geographical location, which indicates a lack of active communication with the terminal devices, the satellite responds by transmitting signals at a reduced transmit power and within a portion of the available channel bandwidth towards the geographical location. The RRC connection can be managed by an RRC protocol.
Claims20
A system comprising:
- at least one hardware processor;
- and
- at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
- allocate a frequency band to a satellite in a non-terrestrial network (NTN);
- determine, by the satellite in the NTN, a channel bandwidth available for data transmissions of a service within the frequency band,
- wherein the satellite is configured to use a transmit power;
- determine, by the satellite, a geographical location supporting the service within the available channel bandwidth,
- wherein the satellite is orbiting over the geographical location;
- detect an absence of a Radio Resource Control (RRC) connection between at least one terminal device and the satellite,
- wherein the at least one terminal device is within the geographical location, and
- wherein the RRC connection between the satellite and the at least one terminal device is managed in accordance with an RRC protocol;
- and
- in response to detecting an absence of the RRC connection between the at least one terminal device and the satellite, transmit signals, via the satellite, at a reduced transmit power and within a portion of the available channel bandwidth, towards the geographical location.
A non-transitory, computer-readable storage medium comprising instructions recorded thereon, wherein the instructions when executed by at least one data processor of a computer system, cause the computer system to:
- allocate a frequency band to a satellite in a non-terrestrial network (NTN);
- determine, by the satellite in the NTN, a channel bandwidth available for data transmissions of a service within the frequency band,
- wherein the satellite is configured to use a transmit power;
- determine, by the satellite, a geographical location supporting the service within the available channel bandwidth,
- wherein the satellite is orbiting over the geographical location;
- identify, by the satellite, an absence of a Radio Resource Control (RRC) connection between a terminal device and the satellite,
- wherein the at least one terminal device is within the geographical location,
- wherein the RRC connection between the satellite and the at least one terminal device is managed by an RRC protocol;
- and
- in response to the identified absence, adjust transmit power and/or the available channel bandwidth associated with the satellite for the data transmissions of the service to the geographical location,
- wherein the transmit power and/or the bandwidth associated with the satellite are reduced.
A method comprising:
- allocating a frequency band to a satellite in a non-terrestrial network (NTN);
- determining, by the satellite in the NTN, a channel bandwidth available for data transmissions of a service within the frequency band,
- determining, by the satellite, a geographical location supporting the service within the available channel bandwidth,
- wherein the satellite is orbiting over the geographical location;
- determining a presence of a Radio Resource Control (RRC) connection between at least one terminal device and the satellite,
- wherein the at least one terminal device is within the geographical location,
- wherein the RRC connection between the satellite and the at least one terminal device is managed by an RRC protocol,
- wherein the satellite uses a transmit power and an available channel bandwidth for the data transmissions of the service to the geographical location;
- detecting an absence of the RRC connection between the at least one terminal device and the satellite;
- in response to determining the absence of the RRC connection between the at least one terminal device and the satellite, adjusting transmission power and/or bandwidth associated with the NTN,
- wherein the transmission power and/or the bandwidth associated with the NTN are reduced.
