    Abstract: The present invention relates to wireless networks and more specifically to systems and methods for selecting and implementing communication parameters used in a wireless network to optimize communication between access points and client devices while accounting for effects of adjacent networks. In one embodiment, the present invention includes a Wi-Fi coordinator device that receives packet information from devices within wireless range of the Wi-Fi coordinator. The Wi-Fi coordinator sends the packet information to a cloud intelligence engine which then time shifts the packet information and combines the packet information with other packet information. Using this integrated packet information, the cloud intelligence devices determines the access point settings to improve the operation of the network.

  • Patent number: 9775056
    Abstract: A method and device for performing interference control are provided. The method includes: network side device determines traffic load parameter value of each cell and the measurement parameter between the base stations which random two cells belongs to; For the two cells, the network side device determines an interference control threshold according to the traffic load parameter value of the two cells, and compares the determined the measurement parameter with the interference control threshold, and performs cluster partition according to the comparing result. The network side device performs interference control according to the partitioned cluster. Because the factor of cell traffic load is considered in performing TDD cross link interference control, thus the cross link interference in TDD networking is reduced.

  • Patent number: 9763231
    Abstract: In order to reduce the HS-SCCH overhead, a fixed time allocation approach could be used. In that case, the scheduling time of each VoIP user is semi-static and thus there is no need to transmit e.g. HS-SCCH toward the UE for the initial transmissions, if the UE knows when to receive data on the HS-DSCH and what transport format is used. There are at least two ways of implementing this: 1) HS-SCCH/E-DPCCH signalling to indicate parameters of a first transmission, with subsequent transmissions using the same parameters (and HS-SCCH/E-DPCCH always sent when changes needed), or 2) fixed allocation, RRC signalling used to allocate users and tell the default transport parameters.

  • Patent number: 9736855
    Abstract: Systems and methods for wireless communication are disclosed. In one aspect an access point transmits a message to a first device and a second device on a first channel, the message sufficient to inform the first device to camp on a first channel during a time slot and the message sufficient to inform the second device to camp on a second channel during the time slot. The access point further determines whether the first channel is busy during the time slot. If the first channel is determined to not be busy during the time slot, the access point communicates with the first device on the first channel during the time slot. If the first channel is determined to be busy during the time slot, the access point communicates with the second device on the second channel during the time slot.

The acoustic filtering circuitry includes an acoustic filtering input node and an acoustic filtering output node. The inductive element is coupled in series with the acoustic filtering circuitry between the input node and the output node such that the inductive element is coupled between the input node and the acoustic filtering input node and the acoustic filtering output node is coupled to the output node. The capacitor is coupled in parallel with the acoustic filtering circuitry and the inductive element between the input node and the output node. Providing the inductive element in series with the acoustic filtering circuitry and the capacitor in parallel with the acoustic filtering circuitry and the inductive element provides a highly selective notch filter response between the input node and the output node with high attenuation.

  • Patent number: 9699691
    Abstract: Scheduling self coexistence windows (SCWs) that part of frames transmitted in wireless regional area networks (WRANs) sharing a common channel. A common channel is monitored for a duration of at least a maximum SCW cycle length. The common channel is checked to determine whether a neighbor WRAN scheduled at least one coexistence beacon protocol (CBP) packet with at least one of SCWs and quiet periods (QPs). A SCW schedule is established by setting SCW schedule fields in a modified superframe control header (SCH) such that the newly established SCW schedule does not conflict with any already scheduled SCWs and QPs.

    Abstract: A technology that is operable to release a licensed shared access (LSA) spectrum allocation in a communications network is disclosed. In one embodiment, an evolved node B (eNode B) is configured with circuitry configured to receive, from a spectrum release module located in an evolved packet core (EPC) of the communications network, a spectrum release message requesting the eNode B release one or more selected segments of an LSA spectrum. LSA spectrum release parameters are evaluated for releasing the one or more selected segments of the LSA spectrum. A LSA spectrum release schedule is determined based on the LSA spectrum release parameters. Selected secondary cells (SCells) are deactivated in the communications network based on the LSA spectrum release schedule to release the one or more selected segments of the LSA spectrum.
