The method includes receiving a first downlink synchronization signal from a base station on a first beam pair at a first time associated with a first propagation delay. The method also includes receiving a second downlink synchronization signal from the base station on a second beam pair at a second time associated with a second propagation delay.

Abstract: Reliable detection of the configuration of transmit antennas includes obtaining a data for transmission, encoding the data, and modulating the data. During the modulating of the data, the data may be configured in such a way as to convey the configuration of the antennas through the modulation of the data. An antenna configuration is obtained by obtaining a representation of the antenna configuration, and masking the data with an error correcting code, where the mask corresponds to the antenna configuration.

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: A transmitter in a wireless network configured to utilize a pilot design and channel estimation strategy to reduce pilot overhead, the pilot design based on a channel decomposition of the channel in a ray tracing channel model. A method of using a three tiered pilot design in a millimeter wave broadband (MMB) wireless network to estimate channel state information (CSI) may include assigning a first tier pilot to a first set of resource blocks, assigning a second tier pilot to second set of resource blocks, assigning a third tier pilot in a third set of resource blocks. When two of the pilots are assigned to a common resource block, the lower tier pilot may be given preference over the higher tier pilot.
