    Abstract: A method for processing transmission power level related data includes obtaining channel gain data from at least a served first user equipment and providing performance related data for at least the served first user equipment. The method also includes obtaining determined transmission power level data per group of resource blocks, as determined at a super frame level, and providing transmission power related pilot signals to the served first user equipment. Additionally the method includes obtaining channel quality related information from at least the served first user equipment and adapting the transmission power level per resource block on the frame level, wherein adapting the transmission power level comprises altering the determined transmission power level as determined per group of resource blocks at the super frame level, in dependence on the obtained channel quality related information related to at least the served first user equipment and the obtained channel gain data.

    Abstract: Parameters that define the frequency raster points to be used in an unlicensed band are used to support operation of wireless devices in both licensed and unlicensed frequency bands. Corresponding signaling messages are used to exchange information regarding the device's capabilities, preferences, transmission power, etc. In one method, implemented in a wireless communication device (410) configured to operate in at least first and second frequency bands, a radio access network is accessed (510), using a first radio access mode and the first frequency band. The method further comprises transmitting (520) frequency raster data to the radio access network, wherein the frequency raster data corresponds to the second band, indicates a tuning capability of the wireless communication device (410), and comprises at least a first frequency index and a granularity indicator. Methods and apparatus for maintaining a database of access point capabilities in unlicensed bands are also disclosed.

    Abstract: A method, User Equipment (UE), and network node in an ad-hoc network. The UE determines a node in the ad-hoc network that is able to provide a reference signal comprising a pattern that can be used for synchronization purposes when the UE is in DRX mode in the ad-hoc network. The node is determined by requesting the node to indicate whether the node is able to provide the reference signal, and receiving an accept signal or message from the node. The UE then receives the reference signal from the determined node, enters DRX mode, and uses the received reference signal to maintain synchronization while in the DRX mode.
