摘要： A method in a first base station for supporting DTX is provided. The first base station serves a first cell being in an active mode. The first base station communicates with a user equipment within the first cell. The first base station is comprised in a radio communications system further comprising the user equipment and a second base station serving a second cell being in a non observable mode. The first base station sends (602) to the second base station, a request to switch the second cell state from a non observable mode to an observable mode. It further sends (603) to the user equipment or to the second base station, a request to perform signalling between the user equipment and the second base station for quality measurements. The first base station then obtains (604) information that handover is feasible, based on quality measurement of the performed signalling. The first base station sends (605) to the second base station, a request to prepare handover of the user equipment from the first cell to the second cell, and further (606) to the user equipment, a command to perform handover to the second cell.

摘要： A Radio Base Station (RBS) and method of operating the same are provided. The RBS may enable a fast and flexible reconfiguration of the system from a first configuration to a second confirmation where the RBS is triggered to initiate a system reconfiguration and the reconfiguration is performed by starting a new cell with the wanted new configuration in parallel with the original cell. During a certain time period, both the original and the new cell are available. Thereafter, the original cell is shut down. The time offset between the start up of the new cell and the shut down of the original cell may be long enough to ensure that user equipment associated with the original cell can be handed over or can reselect the new cell. The time offset may be short enough to reduce the interference between the original and new cells.

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： A method includes determining channel quality feedback information characterizing the channels statistically and calculating, based on the channel quality feedback information, a robustness related measure, such as outage capacity, associated with an on-frequency mode of operation and a robustness related measure, such as an outage capacity, associated with a frequency translated mode of operation. The method includes selecting the on-frequency mode of operation or the frequency translated mode of operation that maximizes the robustness related measure, such as outage capacity. The method also includes transmitting a message to other devices to operate in the selected on-frequency or a frequency translated modes. The method also includes performing maximum ratio combining or interference rejection combining, by at least one of the other devices, when the message indicates to operate in the frequency translated mode.

摘要： In a first antenna mode in a multi-antenna port radio access node, a set of logical antenna ports and its associated resource elements are mapped to a first set of physical antenna ports. Each physical antenna port comprises at least one power amplifier. Switching from first antenna mode to a second antenna mode is initiated upon receipt of information triggering antenna mode switching at a first point of time. During a time interval from the first point of time to a second point of time, the logical antenna ports are re-mapped to a second set of physical antenna ports. At the second point of time, at the end of the time interval, the antenna mode is switched to a second antenna mode by changing supply of power to each physical antenna port represented in the first set of physical antenna ports but not in the second set of antenna ports.
