摘要： A radio base station, a relay node and a respective method therein are provided for communicating data to a user equipment, the relay node being associated with the base station, wherein a downlink transmission to the user equipment is scheduled on subframe(s) available for the base station. The method in the radio base station comprises detecting that at least a part of the available subframes are not needed for downlink transmission to the relay node; and un-reserving at least one of the not needed subframes. The method further comprises transmitting, to the relay node, a release notification message notifying the relay node of the unreserved subframes for enabling the relay node to use the unreserved subframes for downlink transmission.

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： A method, apparatus, and system are described relating to at time when a wireless terminal reports an event to a network. An event to be reported to the network is detected by the wireless terminal. A communications condition affecting a communication between the wireless terminal and the network is determined, and based on the detected communications condition, a dynamic time-to-trigger period is adjusted so that the event is reported by the wireless terminal to the network before the time-to-trigger period expires.

摘要： In methods and devices for controlling a TCP proxy server, the TCP-proxy initial window size is set based on TCP RTT measurements. This is possible because the TCP proxy has knowledge about both sides Round Trip Time RTT values just after opening the TCP connections. The proxy can set its initial window size higher in the download case if it notices that the RTT in the link between the proxy and internet is shorter than the RTT in the other link, typically a wireless link. In the opposite case, when the RTT in the link between the proxy and internet is longer than the RTT in the other link, typically a wireless link, the TCP proxy can be configured to send more Acknowledgements (ACKs) to increase the internet TCP server congestion window size faster.

摘要翻译： 在用于控制TCP代理服务器的方法和设备中，基于TCP RTT测量来设置TCP代理初始窗口大小。 这是可能的，因为TCP代理在打开TCP连接之后有关于双向往返时间RTT值的知识。 如果代理和互联网之间的链接中的RTT短于另一个链路中的RTT（通常是无线链路），则代理可以在下载情况下将其初始窗口大小设置得较高。相反的情况下，当RTT 代理和互联网之间的链接比另一个链路（通常是无线链路）中的RTT长，TCP代理可以被配置为发送更多的致谢（ACK），以更快地增加互联网TCP服务器拥塞窗口大小。
