  • Patent number: 8059593
    Abstract: A distributed channel allocation method and a wireless mesh network with the same are provided herein. By the distributed channel allocation, interference situations are avoided in a wireless network communication, and the allocated bandwidth can then be fully utilized. Besides, unnecessary depletion of an allocated bandwidth due to the interference can be avoided. By this method, a time division technique is applied for dividing a transmission time of each wireless NIC, and different non-overlapping channels can be assigned to different timeslots. Different from other researches that require a symmetrical number of the NICs between a receiving node and a transmitting node, in this method, a unique wireless NIC may communicate with the wireless NICs. The method provides the feature that the number of the NICs on a certain node can be adjusted to meet a communication requirement, by which the efficiency of a network flow is also significantly improved.

  • Patent number: 8036674
    Abstract: A method predicts resource allocations in a wireless network including a set of base stations (BSs). Each BS is in a cell, and serves a set of mobile stations. A sequence and rule of resource allocations are defined for all of the BSs. Previous resource allocations are acquired from the BSs in adjacent cells. In each BS, for a next allocation, inter-cell interference (ICI) is predicted independently for the set of MSs in the cell based on the previous resource allocations by the BSs in the adjacent cells and the sequence and rule of resource allocations. Then, each BS allocates the resources to the MSs in the cell based on the ICI and the previous resource allocations.

    Abstract: Controlling access by a User Equipment (UE) to a cellular network may be effected by: receiving an instruction at the UE from a base station of the cellular network regarding transmission by the UE over a Random Access Channel (RACH) of the cellular network; and controlling when transmissions are made from the UE over the RACH, on the basis of the received instruction. In some cases, a transmission over the RACH may be made in response to the received instruction, which gives permission for the UE to transmit if it has data to send. In other cases, the instruction specifies a Group Identifier, which is compared with a Group Identifier specific to the UE and transmission over the RACH may be avoided based on the comparison. In particular, the UE may be a Machine Type Communication device.

  • Patent number: RE42850
    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.
