Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.
