Abstract: Apparatus and methods are disclosed for power control of uplink transmissions by a user equipment in a way that can reduce interference to neighbor cells. Various aspects of the disclosure decouple the power control for uplink data transmissions from the power control for uplink for a control channel transmissions. For example, one type of power control command may be utilized to control the power the UE utilizes to transmit data channels such as the DPDCH and/or the E-DCH (e.g., the E-DPDCH and the E-DPCCH). Further, another type of power control command may be utilized to control the power the UE utilizes to transmit control channels such as the HS-DPCCH. In this way, the uplink data channels, which can cause substantial interference to neighbor cells, can be power controlled by those neighbor cells to reduce that interference. Moreover, the control channel corresponding to the downlink data transmissions can be controlled by the downlink serving cell, thus ensuring reliable feedback corresponding to those downlink transmissions.

Abstract: Systems, methods, and apparatuses for improved traffic management in wireless communications are disclosed. Aspects of the present disclosure provide real-time assessments to a network by leveraging measurement reports from user equipment (UE). In some aspects, the network utilizes channel quality indicator (CQI) information from each of a serving cell and a neighboring cell to identify UE capabilities and expected UE performance prior to either offloading or rerouting traffic to the UE. Accordingly, based on the received CQI information and a greater understanding of the anticipated UE performance, the radio network controller (RNC) may be better equipped to determine whether to offload and/or reroute the traffic scheduled for transmission to the UE via the neighboring cell or the serving cell.
