Method and apparatus for obtaining reliable E-DCH reception for transmission of scheduling information

摘要

A system to obtain an enhanced-transport format combination (E-TFC) for transmitting a scheduling information (SI) in a soft handoff (SHO) to a serving enhanced Data Channel (E-DCH) cell in a heterogeneous Network (HetNet). The system comprises receiving an E-TFC selection power backoff (ESPB) value from an active macro-cell, the active macro-cell being the service E-DCH cell; determining the E-TFC based on an indicated power of a serving grant minus the received ESPB value and a set of E-TFC power offset value received from the active macro cell, if an MAC-e/i data PDU to be transmitted is multiplexed with the SI; otherwise, determining the E-TFC based on the indicated power of the serving grant and the set of E-TFC power offset value; and transmitting the MAC-e/i PDU to the active macro cell using the indicated power of the serving grant and an enhanced dedicated channel selected based on the determined E-TFC.
