摘要： The present disclosure relates to a method used in a UE for performing a random access to a second base station and an associated UE. The UE has been in communications with a first base station. The method includes: obtaining from the first base station a subframe configuration for the UE, which indicates a first set of subframes assigned to communications between the UE and the first base station and a second set of subframes assigned to communications between the UE and the second base station; and performing the random access to the second base station based on the subframe configuration. The present disclosure also relates to a method used in a second base station for establishing a connection with a UE and an associated second base station.

摘要： The embodiments herein relate to a method in a network node (301) for handling scheduling of a wireless device (305) in a communications network (300). The network node (301) is adapted to communicate wirelessly with the wireless device (305) over a radio channel (310). The network node (301) determines that a data transmission or data reception corresponding to a multi-TTI scheduling message previously transmitted to the wireless device (305) should be at least one of adjusted, interrupted and terminated. The network node (301) transmits, to the wireless device (305), information indicating that the data transmission or data reception corresponding to a previously transmitted multi-Transmission Time Interval, TTI, scheduling message should be at least one of adjusted, interrupted and terminated as determined.

摘要： Systems and methods enabling uplink power sharing for dual connectivity are disclosed. Embodiments are described herein in which a maximum Uplink (UL) power on each link is configured statically, semi-statically, or dynamically. In general, regardless of the embodiment, uplink power for uplink transmissions from a wireless device on two simultaneous links is controlled such that the total uplink power does not exceeds a maximum UL transmission power level while, in some embodiments, taking into account priorities of the two links and/or priorities of various uplink channels transmitted by the wireless device on the two links. Notably, while the embodiments described herein focus on dual connectivity, the embodiments described herein can easily be extended to any number of two or more simultaneous links.

摘要： The present invention provides a unified, rank independent mapping between antenna ports and group/code pairs. Each antenna port is uniquely associated with one code division multiplexing (CDM) group and one orthogonal cover code (OCC). The mapping between antenna ports and group/code pairs is chosen such that, for a given antenna port, the CDM group and OCC will be the same for every transmission rank.

摘要： The present disclosure relates to a method for a base station (BS) BS (re)configuring a user equipment (UE) to switch from a fixed uplink-downlink time division duplex (UL-DL TDD) configuration to a flexible UL-DL TDD configuration. In the method, a signaling message to switch the UE from the fixed UL-DL TDD configuration to the flexible UL-DL TDD configuration is sent to the UE. Then, a set of DL subframes is determined based on the fixed UL-DL TDD configuration and a reference DL TDD configuration of the flexible UL-DL TDD configuration. Thereafter, DL transmissions for the UE are scheduled only within the determined set of DL subframes. The present disclosure also relates to a BS for implementing the method.

摘要： In an example of the teachings disclosed herein, there are multiple signaling options available for triggering a bundled transmission by a wireless device, and a known association between the different signaling options and different TTI bundling sizes. A network node thus indicates to the wireless device which TTI bundling size is desired, based on choosing which signaling option it uses to trigger the bundled transmission. Such signaling allows for the use of variable TTI bundle sizes, i.e., dynamic control of the TTI bundle size used by the wireless device for transmission and yet does not impose signaling overhead or necessarily require new signaling messages or types. Higher layer signaling may be used to activate TTI bundling with implicit signaling then used to dynamically control the actual TTI bundle size used.
摘要翻译：在本文公开的教导的示例中，存在可用于触发无线设备的捆绑传输的多个信令选项，以及不同信令选项和不同TTI绑定大小之间的已知关联。因此，网络节点基于选择用于触发捆绑传输的哪个信令选项，向无线设备指示期望哪个TTI绑定大小。这种信令允许使用可变的TTI束大小，即由无线设备用于传输的TTI束大小的动态控制，但是不施加信令开销，或必然需要新的信令消息或类型。可以使用较高层信令来激活具有隐式信令的TTI绑定，然后用于动态地控制所使用的实际TTI束大小。
