Various embodiments are described that relate to a combined signal. A signal can be transmitted from a transmitter and be received by a receiver. The receiver can be an antenna array that comprises multiple individual antenna elements. At least some of these individual elements can receive the transmitted signal at different reception angles and these received signals can be considered signal copies. The reception angle can influence a power level of a signal copy. Multiple signal copies can be combined together into a combined signal that has a greater power level than the individual signal copies used in the combination.

There is proposed a mechanism for controlling and conducting a discovery procedure of small cells or secondary ceils located in a macro cell or primary cell. The discovery procedure is based on a discovery signal communicated via PDCH and based on a positioning reference signal (PRS). For configuring the signaling of the discovery signal, frequency domain multiplexing for splitting resources of the PRS in the frequency domain for increasing capacity, and/or usage of reserved communication resources for the signaling of the discovery signal are employed. Assistance information is provided to the UE for supporting the discovery of small cells.

A signal conditioning device for conditioning bi-directional radiofrequency (RF) signals in a telecommunications network are provided. The signal conditioning device can allow for the separate conditioning of both downstream and upstream signals in a telecommunication system using a single signal conditioning device disposed at a single location. The signal conditioning device can include first and second line connections and can divide a bi-directional communication signal into downstream and upstream signals. The signal conditioning device can independently condition the downstream and upstream signals using plug-in signal conditioning circuits received into external plug-in sockets.

Multiplexing circuitry is disclosed that includes filtering circuitry, which provides a first transfer function between a common port and a first port and a second transfer function between the common port and a second port. The first transfer function and second transfer function provide a first passband and a second passband, respectively. The first transfer function also has a stopband provided within the second passband of the second transfer function due to the filtering circuitry including a first parallel resonant circuit provided in series in a first filter path being weakly coupled to a second parallel resonant provided in shunt with respect to a second filter path. The weak coupling between the first parallel resonant circuit and the second parallel resonant circuit thus naturally provides a stopband in the first transfer function within the second passband of the second transfer function.
