Abstract: Eliminating or reducing transmission of common signals for enhanced spectral efficiency, improved support for heterogeneous networks, network energy saving possibilities, can be obtained by apparatuses and methods according to certain embodiments. A method for operating a user equipment can include receiving a measurement object from a network for detection of one or more predetermined type cells. A cell search can be conducted. When a predetermined type cell is found, cell specific reference signal hopping parameters can be determined. Then, radio resource management measurement can be performed from the cell specific reference signal hopping parameters.

Abstract: Various communication systems may benefit from an accurate detection method. The method may include determining correlation values between a first sequence of samples and at least one pre-defined sequence, detecting whether at least one first peak exists by comparing the correlation values with at least one first detection threshold. If the at least one first peak exists, the method may further include performing summing of at least a subset of the correlation values and detecting whether at least one second peak exists by comparing the summed correlation values with a second detection threshold.

Abstract: A method and apparatus for a transmission mode with user equipment (UE) independent physical downlink shared channel (PDSCH) scrambling for inter-cell and intra-cell PDSCH-to-PDSCH interference cancellation. A method may include configuring (610) a first identifier (e.g. first RNTI) for a first UE. The method may also include performing at least one of indicating (620) (e.g. semi-statically) a second identifier (e.g. PDSCH RNTI own) for the first UE, or indicating (630) (e.g. semi-statically) a third identifier (e.g. PDSCH RNTIJnt) for the first UE. The first identifier (e.g. first RNTI) is for at least one of operation of physical downlink control channel (PDCCH) of the first UE, or operation of PDSCH of the first UE if the second identifier (e.g. PDSCH RNTI own) is not indicated to the first UE; the second identifier (e.g. PDSCH RNTI own) is for at least one of scrambling or descrambling PDSCH of the first UE; and the third identifier (e.g. PDSCH RNTIJnt) is for at least one of scrambling or descrambling a PDSCH of a second (e.g. interfering) UE. The transmission of the second UE may cause interference on the reception of a PDSCH at the first UE.
