Abstract: To reduce the duration of a cyclic prefix used for a multiple input, multiple output (MIMO) communications channel, delay spread variations for different transmit/receive beam pair combination is estimated and used for fast beam switching and to support single user MIMO (SU-MIMO) even when the CP difference between two beams is large. Beam switching reference signals are employed to estimate delay spread exceeding current CP, and to support beam switching. CP covering sub-clusters within clusters for the MIMO channel are exploited to reduce the CP requirement and improve efficiency. Any one of a number of different CP durations may be selected for each different mobile station, using one of a finite set of subframe configurations for which the CP durations of different symbol locations within the subframe are predefined. Dynamically switching subframe configurations by the system accommodates high mobility.

Abstract: Time, frequency and spatial processing parameters for communications between a base station and a mobile station are selected by transmitting synchronization signals in multiple slices of a wireless transmission sector for the base station, and receiving feedback from the mobile station of at least one preferred slice of the multiple slices. In response to selection of one of the slices as an active slice for communications between the base station and the mobile station, reference signals are transmitted in the selected active slice using a corresponding selected precoder and/or codebook. The mobile station estimates and feeds back channel state information (CSI) based on those reference signals, and the CSI is then employed to determine communication parameters for communications between the base station and mobile station that are specific to the mobile station.
