Abstract: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one station, at least one access point, and at least one non-cooperative transmission source. The method includes steps of generating a matrix of each instance of request-to-send (RTS) messages received by the access point during a specified observation cycle, recording, in a memory of the access point, a number of cumulative RTS messages received from the station, calculating a cumulative distribution function (CDF), based on the recorded RTS message instances in the memory, for a probability of the presence of an aggressive transmission signal by the non-cooperative transmission source within a transmission range of the access point, and determining the presence of the aggressive transmission signal based on the calculated CDF being greater than a predetermined threshold.

Abstract: A method for allocating aggressive signal carriers in a target band of a wireless communication network is provided. The network includes at least one long term evolution (LTE) node and at least one non-LTE transmission source. The target band includes at least two adjacent pairs of contiguous radio frequency (RF) channels. The method includes steps of scanning each contiguous RF channel of the target band to measure a respective value of non-LTE RF energy therein, determining, from the measured non-LTE RF energy, that a first one of the contiguous RF channels is occupied by a non-LTE carrier, and allocating an LTE carrier to a second one of the contiguous RF channels, different than the first one of the contiguous RF channels, based on the determination.

Abstract: Systems and methods presented herein enhance WiFi communications in a RF band where conflicting LTE signaling exists. In one embodiment, a system includes a processor operable to detect the WiFi communications between a UE and a wireless access point of a WiFi network, to identify errors in the WiFi communications, and to determine a periodicity of the errors based on the LTE signaling structure. The system also includes an encoder communicatively coupled to the processor and operable to encode the WiFi communications with error correction, and to change the error correction based on the periodicity of the errors in the WiFi communications.

Abstract: The present system and method provides a spatial multiplexing scenario that is performed purely in the analog domain when transmit and receive arrays are in Line of Sight (LoS) and hence significantly reduce the DSP requirements of massive MIMO systems.

Abstract: Systems and methods presented herein provide for an LTE wireless communication system operating in a Radio Frequency (RF) band with a conflicting wireless system. The LTE system includes an eNodeB operable to detect a plurality of UEs in the RF band, to generate LTE frames for downlink communications to the UEs, and to time-divide each LTE frame into a plurality of subframes. The eNodeB is also operable to condense the downlink communications into a first number of the subframes that frees data from a remaining number of the subframes in each LTE frame, and to burst-transmit the first number of the subframes of each LTE frame in the RF band.

Abstract: Systems and methods presented herein provide for improving communications when encountering aggressive communication systems. In one embodiment, a communication system comprises a wireless access point operable to link a first user equipment (UE) to a WiFi network via a contention based mode that directs the WAP to share radio frequency spectrum with other WAPs. The communication system also comprises a communication processor operable to query at least the first UE to determine aggressive radio frequency (RF) band activity by another communication system in range of the WAP, to determine that the aggressive RF band activity by the other communication system is pushing communication with the first UE via the WAP below a threshold level, and based on the determination, direct the WAP to switch to a contention free mode to communicate with the first UE in contention free mode.
