摘要： Techniques for the secure generation of a set of encryption keys to be used for communication between a wireless terminal and an assisting base station in a dual-connectivity scenario. An example method includes generating (810) an assisting security key for the assisting base station, based on an anchor base station key. The generated assisting security key is sent (820) to the assisting base station, for use by the assisting base station in encrypting data traffic sent to the wireless terminal or in generating one or more additional assisting security keys for encrypting data traffic sent to the wireless terminal while the wireless terminal is dually connected to the anchor base station and the assisting base station. The anchor base station key, or a key derived from the anchor base station key, is used (830) for encrypting data sent to the wireless terminal by the anchor base station.

摘要： The present invention relates to a method and arrangement in base station for scheduling user equipments. The base station is adapted to schedule communication from user equipments by sending contention based grants comprising information indicating if the contention based grant should be used for initial transmission or for retransmission. If it is detected that data is not correctly received due to a collision, the information in a following contention based grant is set to indicate that said contention based grant is to be used for initial transmission, while if data is not correctly received, but no collision is detected, the information is set to indicate that the contention based grant is to be used for retransmission. Corresponding method and arrangement in a user equipment is described.

摘要： The present invention relates to method and arrangements for using an identifier of a predefined type, e.g. an RNTI identifying one configuration on an out-band control channel for activating the configuration identifiable by that identifier. The identifier is sent from the network to the UE, when a configuration corresponding to that identifier is to be activated. This implies that both the UE and the radio base station comprise a mapping between each configuration and the corresponding identity of each configuration.

摘要： An object of the present invention is to provide a mechanism for improving coverage in a wireless communications system. The object is achieved by a method in a sending node (210) for transmitting a data unit to a receiving node (220). The data unit comprises a number of bits. The sending node (210) and the receiving node (220) are both comprised in a wireless communications system (200). According to the method, the sending node (210) obtains (606, 810) a value n associated with the data unit. Then, the sending node (210) selects (608, 814) a transmission time instance depending on n, such that a function exists that uniquely associates the selected transmission time instance with n. Finally, the sending node (210) transmits (612, 818) the data unit to the receiving node (220) in the selected transmission time instance, without the value n.

摘要： In a method and a system Radio Link Control (RLC) Status Reports in a cellular radio system employing Acknowledge Mode (AM) RLC are not delivered in sequence, thereby obtaining an increased peak throughput. Thus, even when an in-sequence delivery exists, for example if the system uses HARQ transmission, it is not used for data related to the RLC status report.

摘要翻译： 在采用应答模式（AM）RLC的蜂窝无线电系统中的方法和系统中无线链路控制（RLC）状态报告不是按顺序递送的，从而获得增加的峰值吞吐量。 因此，即使存在顺序递送，例如，如果系统使用HARQ传输，则它不用于与RLC状态报告相关的数据。
