METHOD AND SYSTEM FOR OPPORTUNISTIC HYBRID RELAY SELECTION SCHEME FOR DOWNLINK TRANSMISSION

摘要

An opportunistic hybrid-relay selection scheme for downlink transmission selects between cooperative relay and single relay schemes based on the channel conditions (e.g., signal-to-noise-ratio (SNR)) between the base station (BS) and RSs (i.e., BS-RSs link) and RSs and mobile station (MS) (i.e., RSs-MS link), respectively. In another selection scheme, a selection between the single relay (e.g., best-relay) transmission scheme or the cooperative-relay transmission scheme may be determined based on transmission paths (e.g., line-of-sight, obstructed-light-of-sight, non-light-of-sight) and channel conditions (e.g., SNR) between the BS-RSs link and the RSs-MS link, respectively.
