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 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.

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： The present invention relates to a method and a Radio Base Station (RBS) in a wireless communication system that enable a fast and flexible reconfiguration of the system from a first configuration to a second configuration. This is achieved by a solution 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 should be long enough to ensure that all UEs associated with the original cell (active, dormant or idle) can be handed over to or can reselect the new cell. However, the time offset should also be short in order to minimize the interference between the original and the new cell.
摘要翻译：无线通信系统中的方法和无线基站技术领域本发明涉及无线通信系统中的方法和无线基站（RBS），其能够使系统从第一配置到第二配置的快速和灵活的重新配置。这通过解决方案来实现，其中RBS被触发以启动系统重新配置，并且通过使用所需的新配置与原始单元并行启动新单元来执行重新配置。在一段时间内，原始和新的单元都可用。此后，原始电池被关闭。新小区的启动与原始小区的关闭之间的时间偏移应该足够长以确保与原始小区（活跃，休眠或空闲）相关联的所有UE可以被移交给或可以重新选择新的小区细胞。然而，为了最小化原始单元和新单元之间的干扰，时间偏移也应该较短。

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： The present invention relates to a method and arrangement in a user equipment unit for activation of downlink component carriers. Even though configured to monitor multiple component carriers,a user equipment does not start to monitor them immediately but only one, or very few, carriers. Only if it decodes a DL assignment it will start to monitor multiple component carriers. After one, or possibly multiple, subframes where the UE is not scheduled anymore it falls back to its original state, i.e. it only monitors one (or very few) component carriers.

摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analysing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.
