A first resource assignment can be received in a first TTI. A first set of resources for receiving a first portion of a first DL user data in the first TTI can be determined based on the first resource assignment. A second set of resources for receiving a second portion of the first DL user data in the first TTI can be determined based on the first resource assignment. A resource location of a first DMRS associated with the first portion of the first DL user data in the first set of resources can be determined. A resource location of a second DMRS associated with the second portion of the first DL user data in the second set of resources can be determined. The first DL user data corresponding to at least a first TB can be received from the network in the first TTI in the first and second set of resources. The first portion of the first DL user data in the first set of resources can be demodulated. The first portion of the first DL user data can be demodulated based on the first DMRS. The second portion of the first DL user data can be demodulated based on the second DMRS. A second resource assignment can be received in a second TTI. A third set of resources for receiving a first portion of a second DL user data in the second TTI can be determined based on the second resource assignment. A fourth set of resources for receiving a second portion of the second DL user data in the second TTI can be determined based on the second resource assignment. A resource location of a third DMRS associated with the second portion of the second DL user data in the fourth set of resources can be determined. The second DL user data corresponding to at least a second TB can be received from the network in the second TTI in the third and fourth set of resources. The first portion of the second DL user data can be demodulated based on the first DMRS. The second portion of the second DL user data can be demodulated based on at least the third DMRS.
