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 1):
An apparatus for implementation in a user equipment device (UE), the apparatus comprising:\n one or more processors, wherein the one or more processors are configured to:\n generate first spread information comprising applying a first spreading code to information; \n map the first spread information to first locations of a first cluster, wherein the first cluster comprises a plurality of subcarriers in a frequency direction across a plurality of orthogonal frequency division multiplexed (OFDM) symbol durations in a time direction, and wherein the first locations correspond to each subcarrier of a first symbol of a plurality of OFDM data symbols of the first cluster, wherein the first spreading code is applied in at least the frequency direction; \n generate first pilot information comprising using a first orthogonal code; \n map the first pilot information to second locations of the first cluster, different from the first locations of the first cluster; \n generate a first signal for uplink wireless transmission to a cellular base station via wireless communication circuitry and a first antenna, wherein the first signal includes the first cluster; \n generate second spread information comprising applying a second spreading code to the information; \n map the second spread information to third locations of 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 orthogonal code is different from the first orthogonal code, and wherein the third locations correspond to each subcarrier of a first symbol of a third plurality of OFDM data symbols of the second cluster, wherein the second spreading code is applied in at least the frequency direction; \n generate second pilot information comprising using a second orthogonal code; \n map the second pilot information to fourth locations of the second cluster, wherein the fourth locations correspond to the same plurality of subcarriers and OFDM symbol durations as the second locations; and \n generate a second signal for uplink wireless transmission to the cellular base station via wireless communication circuitry and a second antenna, wherein the second signal includes the second cluster.
