Embodiments include methods, by a user equipment (UE), for receiving physical data channel transmissions from a wireless network. Such methods include receiving, from the wireless network, configuration information including: a first indication of one or more frequency-domain resource allocations for respective corresponding one or more physical data channel transmissions by respective corresponding one or more sources configured by the wireless network, and one or more second indications of further characteristics of the physical data channel transmissions. Such methods also include, based on the second indications, determining the number of frequency-domain resource allocations indicated by the first indication. Such methods also include receiving, from the wireless network, the determined number of physical data channel transmissions based on the respective indicated frequency-domain resource allocations. Other embodiments include complementary methods performed by a wireless network, and UEs and wireless networks configured to perform such methods.
