摘要： The present invention relates to methods and arrangements in a base station and a user equipment for determining an uplink transmission timing correction for communication in a telecommunication system in which aggregation of component carriers is applied. The base station receives a signal from the user equipment on a uplink (UL) component carrier and measures the arrival time of the signal. A timing correction of the UL transmission timing based on the arrival time of the signal is determined. Thereupon the base station determines for which of the uplink component carriers used by the user equipment the timing correction is valid. The timing correction and the validity information is sent to the user equipment. The user equipment adjusts the UL transmission timing for each UL component carrier the timing correction is valid for.

摘要： Methods and user equipment are provided for activation of downlink component carriers. Even though configured to monitor multiple component carriers, a user equipment unit does not start to monitor them immediately, but instead monitors only one or a few carriers initially. Once a downlink scheduling assignment is received, the user equipment unit will then monitor additional component carriers. After one or more subframes where the user equipment unit is not scheduled, the user equipment unit returns to its original state where it monitors one or a few carriers.

摘要： It is presented a method performed in a first network node. The method comprises the steps of: receiving an uplink transmission from a mobile communication terminal; determining, based on content of the uplink transmission, information to be transmitted over a first communication channel when the content comprises control data intended for a second network node; transmitting the information over the first communication channel to the second network node when the information is to be transmitted over the first communication channel; and transmitting the information via a second communication channel, the second communication channel being physically separate from the first communication channel, when the information is not to be transmitted over the first communication channel. A corresponding network node is also presented.

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： 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 technique for operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. A method implementation of this technique comprises a step of operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals for a first set of terminal devices. The method comprises the further step of selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference nodes as another network node of the heterogeneously deployed network that has a larger nominal transmit power.

摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.
