Abstract: Systems and methods enable distribution of data transfer capacity in a WWAN between mobile devices. The data transfer capacity is given by a data plan for the respective mobile device. The systems and methods register first and second mobile devices with a transaction service as acquirers and providers, respectively, of data transfer capacity. The systems and methods detect when a first mobile device indicates a desire to acquire data transfer capacity, identify one or more second mobile devices that are located within reach for short-range communication with the first mobile device, and connect the first mobile device by short-range communication to one of the second mobile devices such that the first mobile device is tethered to the WWAN by this second mobile device. The systems and methods may also distribute authentication data to enable the first mobile device to be authenticated by the second mobile device.

Abstract: A method and apparatus for controlling a radio receiver circuit are disclosed. The radio receiver circuit is adapted to receive data over a communication channel, over which data is transmitted in transmission time intervals, each comprising at least one time slot. Data transmitted in one or more such time slots comprises a control sequence selected from a finite predefined set of control sequences. The method comprises determining correlation values between a received control sequence of said one or more time slots of a transmission time interval and each of the defined control sequences. Furthermore, the method comprises determining, based on said correlation values, whether any data is transmitted in the transmission time interval, and, in response to determining that no data is transmitted in the transmission time interval, disabling at least part of the radio receiver circuit during at least part of the remainder of the interval, for saving power.
