Abstract: A preferred A-interface resource on a first connection leg is determined by a mobile switching center server based on information on capabilities of a base station subsystem and on characteristics of second connection leg of a connection. A request message is transmitted to the base station subsystem, which requests a connection according to the preferred A-interface resource. The request message is processed by the base station subsystem and an A-interface resource is selected for the user plane connection.

Abstract: Systems and techniques for handover management between macro base stations and home base stations. Upon receiving a measurement report from a user device including a physical cell identity and frequency pair associated with a candidate handover home base station, a macro base station transmits a message to a home base station gateway to obtain cell global identifiers of specified home base stations, which may include home base stations associated with a list of physical cell identifiers and frequency pairs including the pair received in the measurement report. Upon receiving the cell global identifiers, the base station identifies a handover target and performs signaling to the user device to direct handover to the target.

The operating includes switching off of a number of power amplifiers of a base station so that at least one power amplifier of the base station is left on, if level of load in the communications network is detected as being low; and switching of a signal of the at least one power amplifier to antennas, to which power amplifiers of the number of power amplifiers are assigned.

Abstract: An allocation of downlink resources is received, which are monitored on l layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate l reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data.

Abstract: Delivery of protocol data units or other suitable data or information units in various communication systems can be enhanced by appropriate methods and devices. For example, in-sequence delivery of protocol data units received in parallel from several lower-layer acknowledged-mode protocol entities may benefit from timers and/or forwarding status reports. A method can include observing a gap in a sequence of protocol data units received from a plurality of lower-layer protocol entities providing data transfer. The method can also include starting a timer upon the gap observation. The method can further include preventing the gap from blocking delivery of service data units to a higher layer, when the timer expires. The method can additionally include detecting a forwarding-status report. The method can also include immediately proceeding with data delivery to higher layer, containing the gaps because of the lack of forwarding at handover.

The method can also include transmitting the enhanced physical hybrid automatic repeat request indicator channel in semi-static time and frequency resources reserved for enhanced physical downlink control channel. A predetermined number of enhanced control channel elements to be distributed over a certain number of physical resource block pairs can be configured for the transmission of the enhanced physical hybrid automatic repeat request indicator channel.

Abstract: An approach is provided for acknowledgement bundling. Dynamically scheduling of one or more of subframes per bundling window is performed by reusing an assignment index field (e.g., downlink assignment index (DAI) field). The assignment index field has a value greater than or equal to number of previously assigned subframes within the bundling window. The bundling window defines a group of subframes for common acknowledgement.
