Abstract: Methods and apparatus for changing the transmission/reception setup of a base station (BS) in a communication network to another transmission/reception setup (such as one using fewer transmit antennas and/or lower channel bandwidths) without affecting communication with user equipments involve “replacing” the existing BS with a “virtual” BS that has the other transmission/reception setup. Replacement can be performed by, for example, ramping down the power of the existing, or first, BS, which has a respective first cell identification (ID), and simultaneously ramping up the power of the virtual, or second, BS, which has a respective second cell ID.

Abstract: A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

Abstract: A radio network controller is operable in both a unicast signaling mode and a bi-cast signaling mode. In unicast signaling mode, the radio network controller is operable to send radio resource control signals to a mobile station through a serving cell. The radio network controller is operable to go into bi-cast signaling mode during a hard handover. In the bi-cast signaling mode, the radio network controller is operable to send radio resource control messages to the mobile station through both the current serving cell and a target cell. The mobile station is configured to listen to both the current serving cell and the target cell for radio resource control messages. User data, however, is transmitted only from the current serving cell to the mobile station.

Carrier-to-interference ratio is used for adapting physical layer properties and/or for deciding on handover. A computer program and apparatuses for implementing the method are also disclosed.

Abstract: A device adjusts the rotational damping of a steering device such that the rotational damping varies depending on whether the rotational motion about a steering axis is caused by a force acting on the steering device of the vehicle or a force acting on the part(s) of the vehicle contacting the ground. The flow of hydraulic fluid in the steering damper partly or wholly is adjusted by a main valve unit that is coupled together with both an attaching part and a steering device. The opening area of the main valve unit is determined by a relative motion between the attaching part and the steering device such that the flow of the hydraulic fluid in a direction from and to the respective damping chambers of the steering damper is controlled depending on the cause of the rotational movement.

Abstract: Methods and devices for detecting a symbol in a radio channel and for cell identification are disclosed. A signal is received from the radio channel and the signal is filtered by a filter being responsive to the symbol thereby establishing a first signal.

A third signal being the ratio between the first signal and the noise floor is established, and the presence of the symbol is detected by detecting a peak in the third signal.

In one embodiment, the mobile station is configured to adjust a correlation threshold used for said scheduled transmission detection to reduce the likelihood of a missed detection.

Abstract: A cell searching procedure is modified to enable a user terminal to determine whether a detected signal originates in a known cell or a new cell having the same cell identifier as the known cell. When a signal is detected, the user terminal determines the cell identifier and timing of the detected signal. If the cell identifier matches a known cell and the timing is outside the timing window of the known cell, the user terminal compares detected signal with a corresponding received signal received from the known cell having the same cell identifier as the detected signal source. The user terminal determines, based on said comparison, whether the detected signal is from the known cell or a new cell.

Abstract: A user equipment (UE) in a mobile communications system is operated in a manner that alleviates or avoids an overload condition in the UE. This involves operating a receiver of the UE to receive one or more data blocks via a channel. In response to a user equipment overload condition being detected, a channel quality indicator (CQI) value is reported to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel. The UE is then operated in a manner that is consistent with the reported CQI value. UE overload conditions include overheating, and an inability to process received data blocks at the rate at which they are being received.
