  • Patent number: 8204007
    Abstract: A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC-e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat request (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC-e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit.

    Abstract: Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell types of base stations are typically deployed within a subscriber's premises and operate at low transmit power, providing a very limited area of wireless coverage. A femtocell is typically deployed within the area of wireless coverage of a conventional macrocell, occupying the same frequency spectrum and timeslots as the macrocell. A problem can be presented to a user equipment terminal that is close to the femtocell but unable to gain access to it, because the transmissions from the femtocell may appear as interference to the user equipment terminal, preventing it from accessing the macrocell which it could otherwise access.

  • Patent number: 8099643
    Abstract: A method and system for minimizing slot wastage by overlapping HARQ regions in a communication system. A control region allocation (CRA) utility defines a group of HARQ regions for transmission of control data. A HARQ region definition includes a starting symbol and a starting sub-channel number for the HARQ region, a number of symbols and a number of sub-channels to define the dimensions of the region and the slot duration for each sub-burst in a sequence of allocated sub-bursts. The CRA utility overlaps one HARQ region with the other to minimize slot wastage. The slots that carry data in one HARQ region overlap un-used slots in another HARQ region or are overlapped with a dummy allocation in the other HARQ region. Since mobile stations do not carry data for the slots with a dummy allocation, the overlap of HARQ regions avoids conflict with the HARQ operation.

  • Patent number: RE43383
    Abstract: In a system for sharing hybrid resources in an independent network, each one of a plurality of stations preferably employs a sharing authority transferring protocol that allows the network control function to be moved from station to station depending on the network traffic. Although a distributed coordination method is normally used in the network, when an individual station determines that a real-time data stream is intended for the station, an apparatus having a method and data format for the use thereof allows control to be transferred to the targeted station. This allows the targeted station to control the sharing of the wireless hybrid resources using a centralized control method in a direct mode for the duration of the real-time service transmission, thereby optimizing network efficiency. As a result of using the distributed control authority of the present invention, a station may be freely subscribe/withdraw to/from the network.
