Abstract: In accordance to embodiments, methods, devices, and systems for determining initial transmissions in grant-free transmissions are disclosed. A UE receives a resource configuration for grant-free (GF) transmissions. The resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers corresponding to one or more RV types. The periodicity parameter defines a period having K transmission occasions (TOs), and each of the KTOs is associated with one RV number in the sequence of RV numbers. The UE performs an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter. The TO is associated with an RV number corresponding to RV0.

Abstract: The present disclosure provides a data processing method, apparatus, and system. The method includes: receiving N data streams sent by a network-side device, and determining a demodulation reference signal DMRS corresponding to each of the N data streams. The method also includes grouping DMRSs corresponding to the N data streams into M groups; mapping each group of DMRSs in the M groups to corresponding resource element (RE) positions, and acquiring port-related information corresponding to each group of DMRSs. The method further includes sending the port-related information corresponding to each group of DMRSs to a terminal device; adding each group of DMRSs in the M groups to data streams; and sending the data streams to which the DMRSs are added to the terminal device.
