Abstract: Methods, systems, and devices for wireless communications are described that provide for dynamic carrier sharing at a radio unit (RU) by multiple operators. Multiple operators may coordinate regarding resource separation such that wireless resources associated with the shared carrier may be split between the operators using, for example, time-division multiplexing, frequency-division multiplexing, and/or spatial-division multiplexing. Signal transmissions to and from the RU, using a carrier that supports multiple operators, may be based on a separation between certain physical layer (PHY) transmissions, where some PHY transmissions to or from the RU may be common for the multiple operators, and other PHY transmissions may use different sets of resources that are respectively associated with the different operators.

A user equipment (UE) may receive one or more control messages from a network entity scheduling a first and second physical uplink shared channel (PUSCH) messages that overlap at least partially in the time domain.
