Abstract: Time tracking in current communication systems may be traditionally based on common reference signals (CRS). However, in certain communication systems, CRS-based time tracking may be impossible to implement due to an absence of CRS in certain subframes or carriers. CRS-based time tracking may also be inappropriate to implement in certain communication systems such as a coordinated multipoint (CoMP) system where control and data may arrive from different cells, and therefore, a UE may assume a wrong cell for CRS-based time tracking. Accordingly, methods, apparatuses, and computer program products for wireless communication are provided in which additional UE specific reference signals (UE-RS) and/or channel state information reference signals (CSI-RS) are made available to the UE so that the UE may have improved channel estimation and/or time tracking performance.

Abstract: The present invention relates to orthogonal frequency-division multiplexing (OFDM) communication systems with four transmit antennas and one or more receive antennas, and in particular to methods for inserting scattered pilots (SPs) into the transmit signals of such OFDM systems, for estimating channel properties on the basis of the scattered pilots, a multi-antenna OFDM transmitter, and an OFDM receiver.

In this manner, the granularity of pilots of the same subset is reduced. This offers increased flexibility in designing the scattered pilot patterns and greater accuracy of the estimated channel properties.

Abstract: AT commands are used for controlling Mobile Termination (MT) functions and GSM/UMTS network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). Application specific access control is an application/service specific access control mechanism for the operator to allow/prevent new access attempts from particular, operator-identified applications/services in the UE in idle mode.

It reduces wasteful signaling overhead by retries from the TE. Through the new AT command interface, the TE can query application specific access control status. Via unsolicited result code (URC), the MT can detect application specific access control applicability status change and report updated status to the TE.
