Title:
PAYLOAD SEGMENTATION AND RESOURCE MAPPING FOR GF TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2021/035573
Kind Code:
A1
Abstract:
A base station may configure a shared time and frequency resource grid for GF transmissions by one or more UEs. A UE may obtain from the base station the configuration information and transmission parameters for a GF transmission. The UE may generate a payload for the GF transmission. The UE may be configured to segment the payload into one or multiple TBs. The UE may be further configured to measure RSRP, repeat the set of TBs, and concatenate the repeated TBs into a TBG. The UE may be further configured to insert a header within each TB, which may carry the transmission parameters and resource mapping information for the TBG. The UE may be further configured to scramble the TBG by a UE-specific multiple access signature. The UE may retransmit a subset of the TBG based on HARQ feedback from the base station.
