Problems solved by technology

In general, downlink soft handover typically uses simultaneous transmissions from different base stations to the wireless terminal, which can be inefficient because multiple copies of the signal are sent to the wireless terminal
Also, multiple redundant over-the-air transmissions can be particularly inefficient for higher bit-rate signals involving IP data

Abstract

Systems and methodologies are described that facilitate supporting multiple connections associated with a wireless terminal. Notifications may be provided to a primary base station upon establishment and / or removal of connections between the wireless terminal and secondary base station(s). Additionally, the multiple connections may be evaluated and a preferred connection from the set of multiple connections may be utilized to transfer data to the wireless terminal over a downlink connection.

Description

technical field [0001] The following description relates generally to wireless communications and, more particularly, to supporting handover and multiple connections in a wireless communications system. Background technique [0002] Wireless communication systems are widely deployed to provide various types of communication; for example, voice and / or data may be provided via such wireless communication systems. A typical wireless communication system or network is capable of providing multiple users with access to one or more shared resources. For example, a system may use various multiple access techniques such as frequency division multiplexing (FDM), time division multiplexing (TDM), code division multiplexing (CDM), and others. [0003] Typical wireless communication systems employ one or more base stations that provide coverage areas. A typical base station is capable of transmitting multiple data streams for broadcast, multicast and / or unicast services, where a data ...
