Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein relate multiplexing transmissions from multiple user equipments (UEs) on the same time-frequency resources. A UE may receive control signaling from a network entity indicating a multiplexing order, a repetition configuration, and a orthogonal cover coding (OCC) configuration to apply to an uplink grant. The repetition configuration may indicate a set of redundancy versions (RVs), a quantity of resource elements (REs) for each RV, and a quantity of repetitions for each RV. The UE may generate a transport block (TB) using the OCC configuration, and the instances of the RVs of the TB may be mapped to REs of the TB based on the multiplexing order and OCC configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a set of reference signal instances within a set of resources. The UE may receive a second indication of a resource element format of a reference signal instance of the set of reference signal instances, the resource element format including one or more null resource elements and one or more reference signal resource elements. The UE may additionally receive, from a base station, a reference signal for estimating carrier frequency offset (CFO) based on the first indication of the set of reference signal instances and the second indication of the resource element format of the reference signal instance. The UE may then communicate with the base station based on receiving the reference signal.
