Abstract:
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.

Claim (Index 15):
A method for operating a base station, the method comprising:\n receiving a first uplink wireless transmission signal from a first antenna of a user equipment device (UE), wherein the first uplink wireless transmission signal comprises a first cluster, wherein the first cluster comprises:\n a plurality of subcarriers in a frequency direction across a plurality of orthogonal frequency division multiplexed (OFDM) symbol durations in a time direction; \n first spread information mapped to first locations of the first cluster, wherein the first spread information is generated at least in part by applying a first spreading code to information, wherein the first spreading code is applied in at least the frequency direction; and \n first pilot information, wherein the first pilot information is mapped to second locations of the first cluster using a first orthogonal code; and \n receiving a second uplink wireless transmission signal from a second antenna of the UE, wherein the second uplink wireless transmission signal comprises a second cluster, wherein the second cluster is associated with the same plurality of subcarriers across the same plurality of OFDM symbol durations as the first cluster, wherein the second cluster comprises:\n second spread information mapped to third locations of the second cluster, wherein the second spread information is generated at least in part by applying a second spreading code to the information, wherein the second spreading code is applied in at least the frequency direction; and \n second pilot information, wherein the second pilot information is mapped to fourth locations of the second cluster using a second orthogonal code, wherein the fourth locations correspond to the same plurality of subcarriers and OFDM symbol durations as the second locations.
