  • Patent number: 10405281
    Abstract: Methods and systems are disclosed for a dynamic minimum receiver level. A base station can transmit a set of access parameters that enable the mobile device to communicate with the base station. The set of access parameters may comprise a first minimum receiver (RX) level that corresponds to a first standard of qualified communications between the mobile device and the base station utilizing carrier aggregation, and a second minimum RX level that corresponds to a second standard of qualified communications between the mobile device and the base station without utilizing carrier aggregation. The mobile device may be configured to receive the set of access parameters and selectively employ the first minimum RX level so as to communicate with the base station within the qualified coverage area according to the first standard of qualified communications.

  • Patent number: 9548770
    Abstract: A method includes communicating to a plurality of user equipment (UE) in a cell using beamforming. The plurality of UE includes a first group of UE in a first sector of the cell and a second group of UE in a second sector of the cell. The method further includes monitoring positions of the plurality of UE in the cell. In addition, the method includes determining that at least one UE of the first group of UE is in a first region of the first sector, which indicates that a beamform corresponding to the at least one UE has a potential of interfering with one or more other beamforms corresponding to the second group of UE. Based on the at least one UE being in the first region of the first sector, beamforming is disabled to the at least one UE.

  • Patent number: 9420474
    Abstract: A method includes communicating data to a plurality of user equipment (UE) in a cell using a plurality of beamforms. Each of the plurality of beamforms has a main lobe and side lobes, where the main lobe is directed toward a corresponding UE of the plurality of UE. For each beamform of the plurality of beamforms, a position of the beamform is determined. Furthermore, it is determined that one or more small cells of the plurality of small cells are available to serve the corresponding UE based on determining that the one or more small cells are positioned within the main lobe of the beamform using the determined position of the beamform and one or more positions of the one or more small cells. Based on the one or more small cells being determined as available to serve the corresponding UE, beamforming is disabled to the corresponding UE from the cell, thereby preventing the side lobes of the beamform from interfering with other radio communications in the cell.

  • Patent number: 9402209
    Abstract: Systems and methods for utilizing linear network coding to efficiently transfer data packets among components within a telecommunications network are provided. In embodiments, a gateway and source cell of a telecommunications network may utilize linear network coding to create a linear combination of data packets (“encoded data packets”). The encoded data packets may be sent to a target cell, where the target cell may decode the data packets. The target cell may send the decoded packets in sequential order to a user device.

  • Patent number: 9301208
    Abstract: Systems, methods, and computer-readable media for managing optimal neighbor data utilizing a user device are provided. Aspects of the present invention relate to a source cell providing instructions to a user device instructing the user device to determine neighbor relation data, such as an internet protocol address, of a target cell. Additional aspects of the present invention concern a user device utilizing a neighbor relation table to determine neighbor relation data, such as an internet protocol address, of a target cell.
