20140080533 | NETWORK CONTROLLED TETHERING OF WIRELESS DEVICES - A method for tethering wireless devices includes assigning, by a wireless communication network access point, a master wireless device as a hotspot to provide communication services for a slave wireless device. The assignment may be based on first channel quality information and second channel quality information. The first channel quality information may be associated with a first communication channel between the master wireless device and the access point. The second channel quality information may be associated with a second communication channel between the master wireless device and the slave wireless device. The method may also include allocating a wireless communication resource to the master wireless device such that the master wireless device is configured as the hotspot. The allocation of the communication resource may be based on a determination that a parameter requirement of the communication resource associated with the master wireless device acting as the hotspot is met. | 03-20-2014 |
20140080534 | SIGNALING TO ENABLE NETWORK CONTROLLED TETHERING OF WIRELESS DEVICES - A method of signaling to enable tethering among wireless devices may include receiving, at a master wireless device, assignment information from a wireless communication access point. The assignment information may indicate that the master wireless device is designated as a hotspot for a slave wireless device. The method also may include determining an availability of an open frequency band for wireless communications, communicating an enabling signal to the slave wireless and receiving a confirmation of receipt of the enabling signal. Further, the method may include determining an allocation of a wireless communication resource over the open frequency band for the master wireless device to act as the hotspot for the slave wireless device. The allocation may be based on the confirmation of receipt of the enabling signal and on a parameter requirement associated with the master wireless device acting as the hotspot for the slave wireless device. | 03-20-2014 |

20150078260 | PARALLEL RESOURCE MANAGEMENT IN WHITE SPACE BANDS USING TRANSMIT POWER CONTROL AND CHANNEL SET ASSIGNMENT - A method and system for parallel resource management in white space bands may use transmit power control and channel set assignment. Channel sets and corresponding network sets for each of L power levels may be assigned for N networks sharing K number of channels. The input may be location information for each of the N networks. The output may be updated channel sets and corresponding network sets for each of the L power levels. The method may assign maximum networks to channel sets with larger power values. The network sets may be constructed such that a number of channels in a corresponding channel set is larger than a maximum node degree of a corresponding interference graph. The method may further take into account re-use possibilities for channels among networks and may accordingly increase spectrum utilization. | 03-19-2015 |
20150078346 | SPECTRUM SHARING IN WHITE SPACE BANDS USING JOINT POWER CONTROL AND CHANNEL ASSIGNMENT - An optimization framework for spectrum sharing in white space bands formulates an objective function as a linear function of channels and power levels, and constructs a linear set of equations based on a general graph model according to constraints, including spectrum usage regulations and/or resource re-use constraints. The optimization framework provides joint power control and channel assignment where the solution is implemented by an algorithm that allocates time/power/channel to each network to avoid interference while re-using time and/or frequency resources. The solution allocates a fair and orthogonal portion of time on each channel for a certain power level to the networks. The solution can be implemented by a central entity having at least location information of the networks and, upon solving the optimization problem, signals scheduling information of each channel assigned. | 03-19-2015 |
