| 20100182974 | Resource Allocation - Apparatus including a transmitter arranged to transmit an indicating acquisition indication channel signature wherein said indicating signature is used to indicate an enhanced dedicated channel resource to be used by a user equipment. | 07-22-2010 |
| 20100322291 | Control Signaling for Multiple Carrier High Speed Uplink Packet Access in Radio Frequency Communication Systems - Systems and methods for providing an efficient mechanism for transmitting information needed to receive a secondary carrier over an existing message protocol on a primary carrier for a multiple carrier capable communications terminal. The receiver terminal may receive, on a primary carrier, a message containing information including a timing offset and a cell identification for a secondary carrier, for example. The communications terminal may then correlate a receiver to receive the secondary carrier without the need for a separate synchronization signal on the secondary carrier. These embodiments result in additional efficiency in a communications system. | 12-23-2010 |
| 20110019655 | METHOD FOR FAST TRANSMISSION TYPE SELECTION IN WCDMA UMTS - In accordance with the exemplary embodiments of the invention there is disclosed a method, apparatus, and executable computer program for receiving information including preamble scrambling codes associated with transmission types in a random access procedure, selecting an appropriate preamble scrambling code based on the received information, and placing the selected preamble scrambling code in a preamble for a random access procedure. Further in accordance with the exemplary embodiments of the invention there is disclosed a method, apparatus, and executable computer programs for decoding a preamble scrambling code of a random access channel transmission received from a user equipment, and determining a transmission type with which the scrambling code is associated. | 01-27-2011 |
| 20110182280 | Synchronization for Device-to-Device Communication - Various example embodiments are disclosed. According to one example embodiment, a method may include synchronizing, by an access node in a wireless network, with a first mobile station, synchronizing with a second mobile station, compiling a device-to-device group, the device-to-device group including at least the first mobile station and the second mobile station, sending a first connection message to the first mobile station, the first connection message including timing advance parameters of both the first mobile station and the second mobile station, and sending a second connection message to the second mobile station. | 07-28-2011 |
| 20110255425 | Methods and Apparatus for Secondary Bandwidth Detection and Allocation - In accordance with an example embodiment of the present invention, a method comprises monitoring a bandwidth allocation of a primary device via monitoring at least one broadcast message sent from an associated base station; determining whether a secondary bandwidth is available based on the monitored bandwidth allocation of the primary device; allocating the secondary bandwidth to a secondary application on a secondary device if the secondary bandwidth becomes available; keeping track of changes in the bandwidth allocation of the primary device; and returning the secondary bandwidth to the primary device when the changes in the bandwidth allocation of the primary device indicates a need for the secondary bandwidth by the primary device. | 10-20-2011 |
| 20110258327 | D2D Communications Considering Different Network Operators - There is stored a database of registration information associating UEs with cells under control of different network operators. In response to a inquiry from a first network operator that a first UE desires direct communications with a second UE, the registration information is used to coordinate between the first network operator and the second network operator to facilitate establishment of a direct communication link between the first UE and the second UE. In various embodiments the facilitating is enhancing the inquiry/page by adding a cell ID of the first UE's cell and adding pre-allocated radio resources in the first UE's cell for use by the second UE in responding to the page, and determining a single network which is not highly loaded and which can allocate resources for the D2D communications and directing one or both UEs to that single network. | 10-20-2011 |
| 20110268004 | ENABLING DEVICE-TO-DEVICE COMMUNICATION IN CELLULAR NETWORKS - According to one general aspect, a method may include communicating, by a first apparatus, with at least a second apparatus via a device-to-device communication link. In various embodiments, the method may also include receiving resource allocations, from a base station. In some embodiments, the method may include determining, based at least partly on the received resource allocations, which resources are allocated to at least the second apparatus for communication with the base station. In various embodiments, the method may include based at least partly upon the resource allocations, determining when to perform direct device-to-device communication, by the first apparatus, with the second apparatus. | 11-03-2011 |
| 20110275382 | Measurements and Fast Power Adjustments in D2D Communications - At a cluster head/first device there is received, from each of at least two other devices with which the cluster head has a respective wireless link, a quality indicator for the respective link observed by the respective other device. The cluster head compiles those received quality indicators into a compressed report, and sends the compressed report to a network entity. In a specific embodiment the cluster head also determines an additional quality indicator of each of those respective links observed by the cluster head by listening to a sounding reference signal sent by the respective other device to the network entity on a PUCCH. Those additional quality indicators are also compiled into the compressed report, as are further quality indicators received from the devices for D2D links between pairs of those other devices that exclude the cluster head. The compressed report can inform how many indicators are above/below a threshold. | 11-10-2011 |
