摘要： Embodiments herein relate to a method in a radio base station for enabling a user equipment to establish a connection in a radio communications network The user equipment is served in a first cell controlled by the radio base station. The radio base station is comprised in the radio communications network. The radio base station detects a failure of a radio link between the user equipment and the radio base station. The radio base station then forwards a user equipment context of the user equipment to a circuitry controlling a second cell when the failure is detected. The user equipment context enables the circuitry controlling the second cell to serve the user equipment and thereby enables the user equipment to establish the connection in the radio communications network.

摘要： Mechanisms for managing interference in heterogeneous networks are disclosed. A macro node triggers a handover of a user equipment (UE) being serviced by the macro node to a low power node (LPN) operating in a closed access operating mode wherein the LPN provides service to member UEs. The UE is a non-member of the LPN. The macro node determines a trigger condition, and based on the trigger condition signals the LPN to provide service to the UE. The macro node also directs the UE to execute the handover to the LPN.

摘要： Embodiments herein relate to a method in a transceiver (400) for enabling control of interference cancelling in the transceiver (400). The transceiver (400) is in a first decoding mode. The transceiver (400) stores a received signal comprising a data block. The transceiver (400) decodes the received signal using the first decoding mode, thereby obtaining the data block. When an event is triggered, the transceiver (400) retrieves the stored signal. The transceiver (400) decodes the retrieved signal using a second decoding mode, thereby obtaining the data block. The transceiver (400) controls the interference cancelling in the transceiver (400), based on the data block decoded using the first decoding mode and the data block decoded using the second decoding mode.

摘要： One aspect of the teachings herein involves the advantageous use of learned statistical information to improve inter-cell interference coordination (ICIC). The network uses historical signal quality measurements collected over time for wireless communication devices operating within its coverage areas to identify those geographical areas where devices generally experience significant levels of patterned interference. In an example case, the network develops a “map” of the geographical areas that are affected by the transmission patterns of neighboring nodes, and it applies the map to ICIC operations, wherein the serving nodes associated with the affected areas incorporate knowledge of the interfering transmission patterns into the ongoing scheduling of users operating in the affected areas.

摘要： A method and apparatus in a base station serving a first cell in a cellular network, for supporting radio resource management, RRM, in the cellular network. The base station obtains measurements (M) of signals transmitted in the first cell and of signals transmitted in at least one neighboring cell and determines a cell isolation factor of the first cell, based on the obtained measurements, the cell isolation factor indicating insusceptibility to interference from signals transmitted in the neighboring cell(s). The determined cell isolation factor is then used to support RRM for terminals in the network, e.g. as a basis for determining whether to employ an RRM scheme or not. Thereby, it is possible to decide to employ the RRM scheme for cells where it is effective and helpful and not in other cells.
