Abstract: Methods, media, and systems are provided for utilizing unused frequency division duplex (FDD) uplink for time division duplex (TDD) operation in a wireless network. For example, an antenna array comprising one or more antenna elements provides a coverage area (e.g., on at least one TDD carrier and at least one FDD carrier). At least a portion of an available FDD uplink is identified. Based on identifying at least the portion of the available FDD uplink, the identified available FDD uplink can be assigned for a TDD operation. The TDD operation can correspond to the at least one TDD carrier. The TDD operation may include receiving uplink control information from a user device via a TDD uplink that is utilizing the available FDD uplink. In some embodiments, the TDD operation may include transmitting a TDD downlink to the user device utilizing the available FDD uplink.

Abstract: Embodiments of the present disclosure are directed to systems and methods for enhanced multi-satellite downlink connectivity. Each of two or more extraterrestrial base stations communicate data in a downlink to a single user equipment (UE). Encoding each downlink with a different and orthogonal code permits the re-use of at least partially overlapping frequency resources without intra-channel interference. The separated data streams can be used either to provide additional redundancy when the same data is communicated on each stream or to increase throughput when at least partially different data is communicated on each stream.

Abstract: Aspects provided herein to provide methods, systems, and a non-transitory computer storage media storing computer-useable instructions to eliminate overlapping spectrum interference. The method begins with assigning a first portion of contiguous spectrum to a first user equipment. A second portion of contiguous spectrum is assigned to a second user equipment. The first portion of contiguous spectrum and the second portion of contiguous spectrum overlap at least partially. Based on the partial overlap, the first user equipment is instructed to communicate on the first portion of contiguous spectrum using a first code and the second user equipment is instructed to communicate on the second portion of contiguous spectrum using a second code. The use of the first code and the second code eliminate interference in the partial overlapping spectrum.
