Abstract:
The present invention relates to a method and arrangements for saving battery power consumption of a UE in mobile telecommunication system. The method comprises the step of checking whether the UE fulfills at least one of the pre-determined criteria that a subscriber explicitly requests to receive paging at extended DRX cycle and that a new cell is not reselected during a pre-determined time. If the at least one of the pre-determined criteria is fulfilled the step of applying an extended DRX cycle is performed.
Abstract:
The present invention relates to methods and arrangements for controlling uplink transmit power to be used by the UE. The UE comprises multiple radio interfaces wherein at least one of the multiple interfaces is a cellular radio interface. The UE stores information comprising a total transmit power budget set aside for use over the multiple radio interfaces of the UE and receives transmit power control commands from a network node on the cellular radio interface indicating whether the UE should increase or decrease or maintain the uplink transmit power on the cellular radio interface. Transmit power levels to be used for uplink transmissions over the multiple radio interfaces based on the received transmit power control commands are calculated, wherein the said total transmit power budget for the multiple radio interfaces is taken into account.

A method in a radio network node for handling a Device-to-Device, D2D, communication is provided. The D2D communication is wireless, and the radio network node is comprised in a wireless communication system. After receiving (201) from a first user equipment, an indication of resources that are currently available in the first user equipment for D2D communication, the radio network node identifies (202) whether or not the first user equipment currently has capacity for a D2D communication based on the received indication. The resources relates to hardware resources, to combined hardware resources and radio resources, or to combined software resources, hardware resources and radio resources.
Abstract:
The present solution relates to a method in a user equipment (110) for providing navigation signals to a navigator device (104) for use in determining the location of the navigator device. The user equipment (110) selects a plurality of satellites whose signals are to be emulated. After determining the position of the user equipment (110), the user equipment (110) translates the determined position to emulating navigation signals using a parameter derived from each of the respective selected satellites. The user equipment (110) transmits, to the navigator device (104), the emulated navigation signals. The emulated navigation signals enable the navigator device to determine the location of the navigator device (104).
Abstract:
A first user terminal and method of operating the first user terminal so as to provide location information associated with the first user terminal to a second user terminal are disclosed. The first user terminal and the second user terminal are comprised within a wireless communication system, which wireless communication system further comprises a plurality of radio base stations of which a first one of the plurality of radio base stations is serving the first user terminal. A signal is received from one of the radio base stations comprising the absolute geographical coordinates corresponding to the location of that radio base station. Pilot signal measurements are performed on the received signal. The absolute geographical coordinates corresponding to the location of the first user terminal are determined based on the performed pilot signal measurements and the received absolute geographical coordinates of the radio base station. The determined absolute geographical coordinates are transmitted to the second user terminal.

Methods and apparatus for scheduling link resources in a wireless communication system (100) are disclosed. In an exemplary method, a first scheduling policy vector (210), or SPV (210), is generated, the SPV (210) including scheduling elements (220) that prescribe a probability of use for each of several corresponding quantities of link resources. In some embodiments the link resources are LTE resource blocks. The SPV (210) is transmitted to a mobile terminal (150) for use in determining a quantity of link resource units to be scheduled in at least a first transmission time interval. The SPV (210) may be transmitted along with a scheduling window parameter that specifies a period of applicability for SPV (210).
