Title:
分散型アーキテクチャのディジタル・ワイヤレス通信システムを設ける方法および装置
Document Type and Number:
Japanese Patent JP4673905
Kind Code:
B2
Abstract:
A communication system (300, 1000) supports Hybrid Automatic Repeat Request (H-ARQ), Adaptive Modulation and Coding (AMC), active set handoff, and scheduling functions in a distributed fashion by allowing a mobile station (MS) (1014) to signal control information corresponding to an enhanced reverse link transmission to Active Set base transceiver stations (BTSs) (301, 303, 304) and by allowing the BTSs to perform control functions (314, 316, 318) that were supported by an radio network controller (RNC) in the prior art. The communication system allows time and SIR-based H-ARQ flush functions at the BTSs during soft handoff (SHO), provides a control channel structure to support scheduling, H-ARQ, AMC functions for an enhanced reverse link, or uplink, channel (414) in order to maximize throughput, and enables an MS in a SHO region to choose a scheduling assignment corresponding to a best TFRI out of multiple assignments it receives from multiple active set BTSs.
