Abstract: Systems and methods presented herein provide for multichannel communications. In one embodiment, a communication system includes a plurality of traffic channels operable to link to a UE via one or more communication networks. The communication system also includes a traffic processor operable to receive a request for data from the UE, to evaluate the traffic channels based on the requested data, to select a first and a second of the traffic channels based on the evaluation, and to convey the data over the first and second traffic channels to the UE.

Abstract: Systems and methods presented herein provide for altering communications of a LTE wireless communication system operating in an RF band with a conflicting WiFi system. In one embodiment, an LTE system includes a wireless base station operable to transmit downlink communications to a UE in the RF band and to receive uplink communications from the UE in the RF band. The LTE system also includes a processor operable to detect the uplink communications from the UE, to estimate a location of the UE based on the detected uplink communications, to determine a communication capability between the UE and the wireless base station based on the location of the UE, and to downgrade the downlink communications from the wireless base station to the UE based on the determined communication capability to avoid interference with the WiFi communication system.

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.

Abstract: Systems and methods presented herein provide for an eNodeB operating in an RF band comprising a conflicting wireless technology. One exemplary eNodeB assigns an ID to a UE, processes a scheduling request for UL data from the UE, processes another scheduling request for second UL data from the UE, determines priorities of the first and second UL data based on priority indicators in the scheduling requests, and grants time and frequency for the UE to transmit the first and second UL data. The eNodeB also waits until the UE performs an LBT operation. The LBT determines whether the granted time and frequency are occupied by another wireless system comprising a different wireless technology. The eNodeB also determines that the first UL data is stale, and transmits the ID to the UE to reserve the granted time and frequency for the second UL data when unoccupied by the other wireless system.

Abstract: Systems and methods presented herein provide for increasing a contention window of a UE employing a LTE communications operating in a radio frequency (RF) band comprising a conflicting wireless technology. In one embodiment, an eNodeB receives a transport block of data from a user equipment (UE). The transport block includes a cyclic redundancy check (CRC). The eNodeB then determines a checksum of the transport block based on the CRC, fails the checksum, and transmits a non-acknowledgement (NACK) of the transport block to the UE based on the failed checksum. The UE, in response to the NACK, increases a contention window and re-transmits the transport block to the eNodeB.

Abstract: Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a pseudorandom number sequence, or “PN sequence”) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.

Abstract: Systems and methods presented herein provide for improving communications when encountering aggressive communication systems. In one embodiment, a communication system includes a WAP operable to link a UE to a communication network via a communication protocol and a communications processor operable with the WAP to detect another communication system operating within a range of the WAP, and to determine that the other communication system is operating via another communication protocol that differs from the communication protocol of the communication network based on UEs in range of the WAP. The UEs are operable to communicate via both communication protocols. The communications processor queries the UEs in the range of the WAP to determine which of the UEs are communicating via the other communication protocol, and estimates a rate of successful communication with the UE via the WAP based on a number of UEs communicating via the other communication protocol.
