摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

摘要： Methods and arrangements for improving the selection of neighbor cells, on which to perform measurements in different situations. The method in a first node involves obtaining information identifying a first and a second set of neighboring cells for a respective first and second measurement category. A third set of neighboring cells is then determined based on at least parts of the obtained information related to the first and second set. Measurements are then performed in a third measurement category on at least part of the cells in the third set of neighboring cells. The methods and arrangements enable combination of information on neighbor cells, obtained in different ways for different measurement categories into a combined set of neighbor cells, which is more suitable for measurements in a certain measurement category than a set of cells previously obtained for performing measurements in said measurement category.

摘要： A telecommunications node (28) comprises a communication interface (36) and a parameter controller (40). The node (28) acquires timing advance (TA) information and angle of arrival (AoA) information through the communication interface (36). The timing advance (TA) information and angle of arrival (AoA) information are based on uplink signals received over a radio interface (32) from one or more wireless terminals (30) that are involved or have been involved in handover. The parameter controller (40) uses the timing advance (TA) information and the angle of arrival (AoA) information to make a determination of size and shape of a cell of a radio access network.

摘要： The invention relates to a method for supporting cell change between frequency layers. The method is performed in a UE and/or a RN node of a wireless communication network deploying two frequency layers. The RN node serves a UE in a cell of a first of the two frequency layers.

摘要： 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.
