Example implementations relate to devices, methods, and computer program products of communication networks in relation to, e.g., involved in initial access from an idle status, connection reestablishment, handover, or synchronization. A terminal apparatus may include: a control module configured to detect receipt of a group information indicative of a group of at least two network apparatuses, the group information being descriptive for a certain configuration of communication parameters enabling the terminal apparatus to communicate with anyone of the network apparatuses of the respective group, and request connecting to at least one of the network apparatuses of the group by use of the certain configuration.

Improving handover time

It is provided a method for adapting a parameter being indicative for a trigger signal for starting measurements, by a first base station of a first radio access network of a first type of radio access technology, of a signal quality of signals being received from a second base station of a second radio access network of a second type of radio access technology. The method includes measuring by a user equipment, which is served by the second base station, the signal quality of signals being received from the first base station, reporting a signal being indicative for the measured signal quality from the user equipment to a network entity, and adapting, by the network entity, a parameter based on the measured signal quality, wherein the parameter is indicative for a trigger signal for starting measuring a further signal quality of signals being received from the second base station.

The present invention relates to methods and apparatuses for providing network access, wherein a connection to a core network is established via a wireless access device and a gateway device. Connectivity of the wireless access device is restricted to a pre-defined group of core network address of a pool of gateway devices with multi-node connectivity to the core network, and a single address is selected to establish the connection to a one of the gateway devices. The gateway device is provided with a relay function for mapping a single input address to a plurality of core network addresses based on a location information of the wireless access device and with at least one co-located decentralized core network functionality.

Decentralizing core network functionalities

Embodiments described herein relate generally to a user equipment ('UE') that is to transmit a handover error report to an access node. An access node may use information in the handover error report to adjust configurations for parameters that are used to make handover decisions. A UE may transmit such a handover error report in response to an undesirable handover procedure from a source access node to a target access node, such as a failed or nearly failed or too early handover procedure. The UE may transmit this handover error report to either the source access node or the target access node or another node.

User equipment handover error reporting

Data bits are mapped to a lower number of slots than the number of slots available for a retransmission frame and control channels are transmitted in all available slots of the retransmission frame. The number of available slots in the retransmission frame is greater than the number of available slots in the original frame.

Method of re-transmitting an original frame

An apparatus (UEA) may generate a zero-tail signal to be transmitted in an LTE/LTE-A cell, by introducing time domain samples with zero power or very low power in specific positions of a time symbol tail. The apparatus (UEA) may transmit the generated zero-tail signal to a base station (eNB), such that a first user terminal (UEA) is located in the cell farther away (e.g. on a cell edge) from the base station (eNB) than a second user terminal (UEB). Thus coexistence of signals sent by user terminals (UEA, UEB) located at different distances from the base station (eNB) within a same receiver window is enabled without inter-symbol interference. The generated zero-tail signal may also be transmitted from the first user terminal (UEA) or from the base station (eNB) in an outdoor system that is detectable by a neighboring indoor system.

A decoding method for decoding information content in at least one data packet, which is transmitted from a sender to a receiver via a data link. The information is represented by a bit sequence, which is transformed into a transmittable redundancy version. The information is initially transmitted for a first time in a first data packet from the sender to the receiver. The information is represented by a first redundancy version, which is self-decodable. An incorrect receipt is confirmed by sending a confirmation from the receiver to the sender. The information is retransmitted at least a second time in a second data packet from the sender to the receiver upon receipt of the confirmation, wherein, for representation of the information, a second redundancy version is used, the selection of which is performed in dependence on a coding parameter, describing whether the redundancy version is self-decodable or not.

Method for adapting a downlink transmit power of a first base station adapted for serving a closed subscriber group. It is described a method for adapting a downlink transmit power of a first base station adapted for serving a closed subscriber group. The method includes scanning a neighborhood of the first base station for a second base station adapted for serving an open subscriber group, wherein the first base station and the second base station use the same carrier frequency, detecting whether the second base station is present within the neighborhood of the first base station, and adapting the downlink transmit power of the first base station depending on the presence of the second base station. It is further described a base station, a computer-readable medium and a program element for carrying out the method.

There is proposed a mechanism for power saving procedures to be conducted in transmission network nodes, such as base stations or the like, in a heterogeneous network environment. A transmission node is set to operate in a sensor mode for conducting traffic monitoring when an operation mode of the transmission node is an inactive state. Information necessary for the traffic monitoring by the transmission node based on detection of random access channel (RACH) signals of neighboring cells is provided. On the basis of results of the monitoring of RACHs of the neighboring cells, it is determined whether the inactive transmission node is to be reactivated.

Power saving procedure in communications network

The present invention refers to handling of an overload in a communications network and to handling of handovers occurring after the handling of handovers in the communications net work, wherein said communications network is based upon a tree topology providing several levels of nodes in said communications network. According to the present invention, in formation about an overload is provided through several levels of nodes in communications network, starting from the node, with regard to which said overload has occurred, and ending with nodes being located in levels arranged upside the level, in which the overload occurred, and being connected directly or indirectly with the node, with regard to which said overload has occurred. When handling a handover from a cell in a node, which is affected by the overload, the handover will be allowed only if the cell comprises at least one node, which is also affected by the overload.
