Patent ID: 7408974

Claim:
A method of providing increased data communication capacity in a sector of a CDMA wireless system using a combination of code division multiplexing and time division multiplexing, wherein the sector includes at least a first subsector and a second subsector, comprising the steps of: transmitting a first carrier signal in the first subsector having a plurality of code division multiplexed subchannels and a predetermined PN code offset, wherein the subchannels utilize a set of spreading codes and wherein the plurality of subchannels carry data for one user of a first group of users for an assigned time slot; simultaneously transmitting a second carrier signal in the second subsector having a plurality of code division multiplexed subchannels and a partially shifted version of the predetermined PN code offset, wherein the subchannels utilize the same set of spreading codes and wherein the plurality of subchannels carry data for one user of a second group of users for an assigned time slot; wherein the first and second carrier signals utilize the same frequency, and wherein the partially shifted version of the predetermined PN code offset provides a code separation between adjacent subsectors.
