Apparatus and method for uplink power control of satellite and terrestrial integrated communication system
First Claim
1. A satellite communication apparatus for performing resource block (RB) allocation for a satellite communication in a satellite and terrestrial integrated communication system, the satellite communication apparatus comprising:
- a controller configured to allocate a first RB to a mobile earth station (MES) when a communication of the MES is requested; and
a communicator configured to transmit a use notification of the first RB to at least one terrestrial base station located in an interference range of an uplink signal of the MES in response to the communication request of the MES,wherein the use notification of the first RB comprises a power control request of a link to which the first RB is allocated, the power control request comprising a power control amount requirement to mitigate an interference of the uplink signal of the MES caused by the at least one terrestrial base station.

Abstract
In a satellite and terrestrial integrated communication system in which a satellite communication system and a terrestrial communication system share and use an identical frequency band, an interference to a mobile earth station (MES) of the satellite communication system using an identical frequency by an uplink signal transmitted to a base station of the terrestrial communication system by a user equipment (UE) may be mitigated. When a communication of the MES is requested, a satellite communication apparatus to perform resource block (RB) allocation for a satellite communication in the satellite and terrestrial integrated system may include a controller configured to allocate a first RB to the MES, and a communicator configured to transmit a use notification of the first RB to at least one terrestrial base station located in an interference range of an uplink signal of the MES.
