摘要： The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

摘要： A cellular communications system that utilizes OFDM in its radio interface is capable of utilizing either a first subcarrier spacing or a second subcarrier spacing. Which of these is presently in use is indicated by generating a first type of synchronization signal in response to the first subcarrier spacing presently being in use, and generating a second type of synchronization signal in response to the second subcarrier spacing presently being in use. Whichever of the first type of synchronization signal and the second type of synchronization signal was generated is transmitted. To distinguish between the first and second types of synchronization signals, a time domain representation of the second type of synchronization signal includes a plurality of instances of the first type of synchronization signal.

摘要： A method in a radio network node for dynamic carrier mode switching is provided. The radio network node is comprised in a radio communications system. The radio network node is configured to operate in a legacy mode and is further configured to operate in a non legacy mode. At least one carrier is operated so that it switches (602) from non legacy mode to legacy mode. When operating the carrier in the legacy mode, the radio network node signals (603) with a user equipment. The user equipment operates in legacy mode, but can not operate in non legacy mode. The radio network node then operates the at least one carrier so that it switches (604) from legacy mode back to non legacy mode.

摘要： The present invention relates to cellular radio communication and in particular to providing information on neighbor cells to enable terminals to perform neighbor cell measurements. In the prior art the terminal attempts to make neighbor cell measurements in a reference signal structure that is the same in the neighbor cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighboring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbor cells.

摘要： A network unit of an own cell is operated in a radio communication system utilizing a radio interface that includes a radio frame made up of a number of sub-frames. The own cell serves one or more user equipments. Operation includes obtaining information about a scheduling of MBSFN data transmissions in one or more neighboring cells. The information thereby obtained is used to generate an information signal that, for a given sub-frame, enables the one or more user equipments to determine whether neighboring cell measurements can be performed using a unicast group of Orthogonal Frequency Division Multiple access (OFDM) symbols. The information signal is transmitted to the one or more user equipments, which can then use the information to determine how to locate cell-specific reference symbols when doing measurements of neighboring cells.
