REITERATED DOWNLINK GRANT DESIGN FOR MULTIPLE TRANSMISSION TIME INTERVAL GRANT SUPPORT IN ECC

摘要

Enhanced robustness for downlink burst transmissions using reiterated grants. A user equipment (UE) may receive multiple transmissions during multiple (e.g. consecutive etc.) transmission time intervals (TTIs) as part of a downlink burst from a base station where at least some of the TTIs may include an iteration of a grant and a data transmission. The grants may contain some common control information for TTIs of the downlink burst as well as an indicator of how may TTIs come before and after. The UE may identify preceding and subsequent TTIs in the downlink burst by decoding any of the grant iterations. If the UE identifies a previous transmission that has not been buffered it may send a negative acknowledgement to the base station. If the previous transmission has been buffered the UE may decode the previous transmission based at least in part on the current grant iteration.
