PER-LINK REDUNDANCY VERSION ASSIGNMENT FOR UPLINK RELAYS

Abstract:

Methods, systems, and devices for wireless communications are described for a relay UE and a source UE to provide transmissions of uplink communications in a decode and forward procedure in which redundancy version (RV) identifications of each instance of a transmission or retransmission are associated with a particular link of the source UE or relay UE. A set of RV sequences may be configured, with the source UE using a first subset of the RV sequences, and the relay UE using a second subset of RV sequences that is non-overlapping with the first subset. A base station or destination UE that receives the transmissions from the source UE and relay UE may thus receive RVs in accordance with the set of RV sequences.
