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.

Abstract: A transmitted signal estimate based on signals received in a layer i within a multiple input, multiple output transmission system and based upon selected constellation points for other, previously processed layers is quantized to a nearest constellation point. A list of candidates headed by the nearest constellation point and with remaining candidates presorted by proximity to the head is selected, for each such quantized estimate based on constellation point selections for previously processed layers. To select K best candidates for the transmitted signal estimates of the current layer i, the proximity of the candidates at the head of each list to the signal estimate for the current layer are compared, and the closest candidate is selected. The list containing the selected candidate is advanced, and proximity of the transmitted signal estimate to all list heads is again evaluated and the closest candidate selected.
