5G NR data delivery for flexible radio services
Embodiments include methods, systems, and apparatuses for receiving a first type of transmission and a second type of transmission. A WTRU may receive a first downlink control information (DCI) during a first downlink (DL) transmission interval allocating first radio resources in the first DL transmission interval for reception of a first type of transmission. The WTRU may receive data from the first type of transmission in the first radio resources. The WTRU may receive data from a second type of transmission in second radio resources that include one or more predetermined regions within the first radio resources. The WTRU may receive a second DCI during a subsequent second DL transmission interval indicating that the data from the first type of transmission was preempted by the data from the second type of transmission. The WTRU may process the data from the first type of transmission based on the second DCI.
