摘要： Systems, methods, and apparatuses for phase-rotated reference signals are provided. In accordance with one implementation, phase-rotated reference signals are transmitted from multiple transmit antennas on the same reference signal (RS) resource elements. The receiver may determine channel coefficients for links corresponding to the multiple antennas, based on the received signals at the RS resource elements. Time-domain filtering or frequency-domain orthogonal codes may be used to determine the channel coefficients for links corresponding to the multiple antennas. The phase-rotation information may be broadcasted in a system information block (SIB) message or signaled in a radio resource control (RRC) message.

摘要： Systems and methods for mobility parameter adjustment and mobility state estimation in heterogeneous networks are provided. The mobility parameters may be adjusted based on the cell change types associated with the mobility procedure. The mobility procedure may be a cell handover procedure or a cell reselection procedure. The cell change type may be dependent on the transmission power level of the UE's serving cell and neighboring cells. In some implementations, the UE may provide a speed information to the serving cell such that the serving eNB may prioritize or optimize the mobility procedure for the UE. The UE may also estimate its mobility state by counting the number of cell changes within certain period of time and applying scaling factors to the number of cell changes based on the associated cell change types.
