A system and method for identifying at least one aggressor cell are described. The method comprises transmitting at least one subframe from at least one base station of a first set of base stations to a second set of base stations, wherein the at least one subframe further comprises of at least one downlink subframe, at least uplink subframe and at least one special subframe.

A communication uplink between a UAV and a base station is established using frequency division duplex (FDD) communication and a communication downlink between the UAV and the base station using time division duplex (TDD) communication. A determination of whether the UAV is located above an antenna height threshold is then made. When the UAV is located above the antenna height threshold, the communication uplink is transitioned from using the FDD communication to using the TDD communication while the use of the TDD communication is continued for the communication downlink. When the UAV is located at or below the antenna height threshold, the use of the FDD communication is continued for the communication uplink and the TDD communication for the communication downlink.

A method for disconnecting a wireless time-division duplex communication link. The time-division duplex communication link being between a first node transmitting during time slots allocated to said first node, wherein a second node is transmitting during separate time slots allocated to said second node, said first node transmitting at a respective one of a plurality of frequency bands during each of said time slots allocated to said first node. The method may include sub-dividing a time slot allocated to said first node into consecutive time intervals; disrupting communication between said first node and said second node by transmitting, using a transmitter, respective interference signals during at least some of said time intervals while maintaining a frequency difference between any pair of consecutive interference signals below a frequency difference threshold, each of said interference signals being transmitted on one frequency band selected from a group of frequency bands, the group of frequency bands comprises the plurality of frequency bands, wherein for at least two of said time intervals said interference signals are transmitted on different frequency bands, wherein the frequency difference threshold does not exceed a portion of a frequency gap between (a) a lowest frequency band of the plurality of frequency bands and (b) a highest frequency band of the plurality of frequency bands.

Disclosed are systems, methods, and non-transitory computer-readable media for clock synchronization in half-duplex communication systems. Devices in a half-duplex system are synchronized based on time stamp values captured by each device that define a specified period of time that is of equal in length. The specified period of time spans two change-over periods to average the jitter and/or drift that occurs during each period. Each device uses these measured lengths to determine the variance in the rates at which the two internal clocks operates, which is then used to synchronizes the internal clocks of the two devices.
