This invention concerns concepts for signaling resource allocation information to a terminal that indicates to the terminal assigned resources for the terminal. The terminal can receives downlink control information (DCI), which comprises a field for indicating the resource allocation information of the terminal. This resource assignment field within the DCI has a predetermined number of bits. The terminal can determines its assigned resource allocation information from the content of the received DCI, even though the bit size of the resource allocation field in the received DCI is insufficient to represent all allowed resource allocations. According to an embodiment, the received bits that are signaled to the terminal in the DCI represent predetermined bits of the resource allocation information. All remaining one or more bits of the resource allocation information that are not included in the field of the received DCI are set to predetermined value. |

Distributed system architecture to provide wireless transmitter positioning
A distributed architecture provides the location of wireless transmitters to mobile devices for positioning, the location determined from at least one of crowdsourcing and wardriving. A server receives location data for wireless transmitters, such as an access point, a femtocell, Bluetooth Transmitter, radio-frequency identification (RFID) and near-field communication (NFC) station etc., from mobile devices.
