Currently deployed cellular data systems limit any user to downlink reception only from a single base station. Recent standardization work on newer revisions of the HRPD and HSPA air-interface technologies relaxes this constraint by allowing multiple base stations to transmit independent data streams targeted towards a single user. The authors characterize the regions of performance gain for this technology, and investigate further improvements using advanced terminal receivers. The scheme is shown to be an effective load-balancing adaptation to bursty traffic at low to moderate loads.
