  • Patent number: 9386467
    Abstract: The present invention has an object to provide a communication system capable of appropriately providing services while improving a data rate using carrier aggregation. In Step ST1408, of a cell1 and a cell2 of a base station A, RRC connection is established between the cell1 and a UE, and the cell1 becomes a primary cell (PCell). Then, in Step ST1418, the cell1 determines to configure the cell2 as a secondary cell (SCell) to be aggregated with the own cell. Then, the cell1 notifies the UE of the above in Step ST1419. Upon this notification, the operation of restricting access to the cell2 from the UE is stopped by an MME, and thereafter, communication between the UE and the cell2 is started in Step ST1422.

  • Patent number: 9350663
    Abstract: A system and method of reducing network congestion whereby significant improvement can be gained by the elimination of catastrophic network congestion failure within a TCP/IP network. Exemplary embodiments are implemented by an improved process for dealing with the retransmission of TCP window data. By reducing packet loss to a grid map and retransmitting only the lost pieces rather than the entire window, congestion can be eliminated. In a traditional TCP implementation, loss of packets within a specified window of data can cause the entire window of data to be retransmitted. This system and method improves this process by allowing only lost packets to be retransmitted and not properly received data that is merely part of a larger grouping that also contained lost data.

  • Patent number: 9351156
    Abstract: Systems and methods are provided for encrypting a data transmission from a base station at the physical layer, such that the data transmission can only be decoded successfully by an intended UE. In an embodiment, a desired signal component, including a data signal for an intended UE, is combined with an interference component to generate a signal for transmission. The interference component is designed such that it falls in a null space of the channel from the base station to the intended UE and is therefore not received by the intended UE. In contrast, for an unintended UE, the interference component is designed to interfere with the desired signal component at the unintended UE, preventing the unintended UE from successfully decoding the data transmission.

  • Patent number: 9300373
    Abstract: In a system using spatial precoding, in the event that reliable channel state information is unavailable, a transmitting node artificially creates a randomization of the precoders applied to the transmitted signal. Different precoding vectors are applied to both transmitted data and demodulation reference signals for each of several groups of time-frequency resources, where the precoding vectors vary randomly or pseudo-randomly from each group of time-frequency resources to the next frequency-adjacent group or groups, or to the next time-adjacent group or groups, or both. In an LTE system in particular, this randomization of precoders can be applied at the resource-block level or, at the level of the Precoding Resource block Group (PRG), for example. Thus, the precoders applied to the transmitted signal vary from one PRG to the next, in a random or pseudo-random fashion.

  • Patent number: 9301314
    Abstract: A device with concurrent long-term evolution (LTE) and WLAN uplink transmission includes a WLAN transceiver coupled to an LTE transceiver via an interface. The LTE transceiver includes an LTE Layer-1 module that determines whether an LTE data downlink activity is scheduled for an LTE downlink sub-frame of an LTE time frame, based on information in a first portion of the LTE downlink sub-frame. When determination is made that the LTE data downlink activity is not scheduled for the LTE downlink sub-frame, a message may be communicated through the interface to notify the WLAN transceiver that the second portion of the LTE downlink sub-frame is available for WLAN communication. The LTE time frame includes multiple LTE downlink sub-frames each including the first portion and a second portion. The first portion provides the information that indicates whether the LTE data downlink activity is scheduled for the second portion of that LTE sub-frame.
