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.
摘要翻译：本发明涉及使用预定义类型的标识符的方法和装置，例如， RNTI识别带外控制信道上的一个配置，用于激活由该标识符可识别的配置。当要激活与该标识符相对应的配置时，将标识符从网络发送到UE。这意味着UE和无线电基站都包括每个配置与每个配置的对应身份之间的映射。

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.
