摘要： The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-I and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.

摘要： A wireless communication method and system are provided. A first wireless communication numerology, e.g., OFDM operating parameters, corresponding to a first operational mode is established. A second wireless communication numerology corresponding to a second operational mode is also established. The first wireless communication numerology is different than the second wireless communication numerology. One of the first operational mode and the second operational mode is selected. One of the first wireless communication numerology and the second wireless communication numerology corresponding to the selected operational mode is used in which communication in the first operational mode and the second operational mode use substantially similar synchronization channels. The present invention also uses the same superframe structure for the first and second operational modes for Ultra-Mobile Broadband (“UMB”) networks and the same frame structure for the first and second operational modes for Long Term Evolution (“LTE”) networks.

摘要： In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.
