  • Patent number: 10778814
    Abstract: A system and method for classifying packets according to packet header field values. Each of a set of subkey tables is searched for a respective packet header field value; each such search results in a value for a subkey. The subkeys are combined to form a decision key. A decision table is then searched for the decision key. The search of the decision table results in an action code and a reason code, one or both of which may be used to determine how to further process the packet.

  • Patent number: 10721598
    Abstract: A first cell device obtains, from a second cell device, multicast information associated with the second cell device, where a first wireless coverage area associated with the first cell device at least partially overlaps a second wireless coverage area associated with the second cell device. The first cell device transmits the multicast information to an element management system, and receives, from the element management system, an instruction, generated based at least on the multicast information, to not use one or more subframes, associated with a multicast transmission session associated with the second cell device, to transmit during the multicast transmission session. The first cell device determines, after receiving the instruction, that the multicast transmission session has been initiated, and causes the first cell device to not use the one or more subframes to transmit during the multicast transmission session associated with the second cell device.

  • Patent number: 10667251
    Abstract: Disclosed is a base station in which the frequency usage efficiency can be improved when the communication bandwidths are asymmetric in the uplink line and the downlink line. A base station can communicate by using a plurality of downlink unit bands and a smaller number of uplink unit bands. A control unit allocates uplink resource allocation information and downlink resource allocation information to a PDCCH which is arranged in each of the plurality of downlink unit bands, and allocates a response signal to the uplink line data to a PHICH which is arranged in the same number of downlink unit bands from the plurality of downlink unit bands as there are uplink unit bands. A transmit RF unit transmits the resource allocation information or the response signal.

  • Patent number: 10652847
    Abstract: A relay station comprising: a time server that supplies time-synchronized pulse data generated every second; and a symbol counter that counts symbol periods used in communication, based on the pulse data. The relay station transfers an upstream signal to a simulcast controller, by including in the upstream signal a first count value of the symbol counter that indicates a timing when synchronization with the upstream signal is established. The simulcast controller calculates a second count value based on the first count value to indicate a timing of transmission of the downstream signal from the relay station to the terminal device, transfers the downstream signal for transmission from the relay station to the terminal device, with the second count value being included in the downstream signal. The relay station starts transmitting the downstream signal based on the second count value.
