Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, encoded packets that are encoded using network coding. The encoded packets may be associated with source packets that represent a data set. The UE may attempt to recover the source packets from the encoded packets received from the base station. Upon failing to recover the source packets, the UE may transmit, over a sidelink channel, a message requesting sidelink assistance in recovering the source packets.

Abstract: Aspects are provided that allow a UE to perform DMRS bundling in different transport blocks of uplink data on PUSCH in response to a configuration from a base station indicating or enabling the UE to perform the DMRS bundling. The UE receives a configuration from a base station indicating to bundle DMRS in different uplink data channel transmissions for joint channel estimation. The UE determines a DMRS bundling window based on the configuration. The UE transmits the bundled DMRS in the DMRS bundling window. The base station performs the joint channel estimation based on the bundled DMRS. Improved link quality between the UE and base station and signal gains may accordingly result from applying DMRS bundling over different PUSCH transmissions.
