摘要:
The invention relates to a method for power reduction and to a communications system, in particular a radio communications system, which allows such a method. The method for data transmission in a radio communications system having a radio interface between at least one, and in particular a large number of, base stations and at least one, and in particular a large number of, subscriber stations, in which one base station can in each case be connected via a radio interface to a number of subscriber stations provides redundantly coded data which, for the connection with at least one first transmission power level, is transmitted such that data loss is accepted. A chosen portion of the coded data is omitted during the transmission, and the transmission power level is, in contrast, chosen to be higher than the first transmission power level, such that the bit error probability is sufficiently low to allow the data to be reconstructed at the receiving station.

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.

Embodiments provide a method and apparatus configured to measure a timing difference to at least one neighbouring base station, cell, NodeB, enhanced NodeB, relay and/or relays, evaluate or generate a time control command depending on the measured timing difference, and send the time control command to a serving base station or NodeB or eNB.

In order to match the bit rate in a communication device, the bits of a bit stream are punctured or repeated, in which case for each bit an updated error value is calculated on the basis of a previously determined error value and an update parameter and a judgment is made on the basis of the updated error value as to whether the corresponding bit is to be punctured or repeated or not. A variable, bit-specific update parameter is used to determine the updated error value of each bit, such that it is possible to achieve a non-uniform puncturing/repetition density.

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.

The present invention relates to methods, apparatuses, a system and a computer program product for reducing a power consumption in low load scenarios. An apparatus can include transmitting means, receiving means and determining means for determining whether a signal quality of a broadcast channel of a wireless network cell is insufficient, wherein the transmitting means may transmit on a wireless access channel an activation information to a further apparatus if the determination is affirmative. The activation information can indicate that disabled transmitting means of the further apparatus should be re-enabled. The further apparatus may include transmitting means, receiving means disabling means for disabling the transmitting means and enabling means for re-enabling the transmitting means, wherein the receiving means can be configured to receive the activation in-formation, and wherein the enabling means may be configured to re-enable the transmitting means if the activation information is received.
