Abstract: Methods systems and devices are provided for coordinating forward link blanking and/or power boosting in wireless communications systems. Some embodiments include two or more bandwidth systems. The bandwidth of one bandwidth system may overlap with the bandwidth of another bandwidth system. This overlap may create interference. Coordinating forward link blanking and/or power boosting may aid in reducing the impact of this interference. Some embodiments utilize flexible bandwidth and/or normal bandwidth systems. Flexible bandwidth systems may utilize portions of spectrum that may not be big enough to fit a normal waveform though some embodiments may utilize flexible waveforms that utilize more bandwidth than a normal waveform.

Abstract: A method for performing symbol timing estimation is disclosed herein. In one approach, the method includes defining a search space in a plurality of estimated magnitudes of channel taps; defining a search window (SW-33) in the search space; and locating a symbol timing estimate index in the search space corresponding to a maximum value of an energy of the plurality of estimated magnitudes of channel taps within the search window (1660). A computer program product having code and a wireless communications apparatus for performing the method are also described herein.

Abstract: A method for performing carrier frequency offset estimation and frame synchronization is disclosed herein. In one approach, the method includes performing a first level frequency discrimination on at least one estimated channel tap to generate a frequency discriminated value; estimating a phase error from the frequency discriminated value; and, determining a predetermined frame synchronization pattern from the estimated phase error. A computer program product having code and a wireless communications apparatus for performing the method are also described herein.

Abstract: Methods systems and devices for supporting voice communications in a wireless communications system are provided. Some embodiments utilize multiple code channels to transmit the voice frames. These embodiments include parallel multi code embodiments offset multi code embodiments and multi user multi code embodiments. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform. Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes. An outer loop power control set point may be adjusted to provide a predetermined frame error rate based on the number of transmitted subframes.
