A method (1400, 1500) performed by a network entity, the method comprising: transmitting, to a user equipment, a first resource assignment in a first transmission time interval, TTI, wherein the first resource assignment defines a first set of resources for receiving a first portion of a first downlink user data in the first TTI, and wherein the first resource assignment defines a second set of resources for receiving a second portion of the first downlink user data in the first TTI, and wherein the second set of resources are configured for Downlink Control Information and are used instead for downlink user data, and the second set of resources do not overlap with the first set of resources, wherein the first set of resources defines a resource location of a first DMRS associated with the first portion of the first downlink user data, and wherein the second set of resources defines a resource location of a second DMRS associated with the second portion of the first downlink user data; transmitting, to the user equipment, the first downlink user data corresponding to at least a first transport block in the first TTI in the first and second set of resources, wherein the first portion of the first downlink user data is arranged to be demodulated based on the first DMRS, and wherein the second portion of the first downlink user data is arranged to be demodulated based on the second DMRS; transmitting, to the user equipment, a second resource assignment in a second TTI, wherein the second resource assignment defines a third set of resources for receiving a first portion of a second downlink user data in the second TTI, wherein the first and third set of resources are configured for downlink user data, wherein the second resource assignment also defines a fourth set of resources for receiving a second portion of the second downlink user data in the second TTI, wherein the fourth set of resources is configured for Downlink Control Information and used instead for downlink user data, and the fourth set of resources do not overlap with the third set of resources, wherein the second resource assignment defines a resource location of a third DMRS associated with the second portion of the second downlink user data in the fourth set of resources, transmitting, to the user equipment, the second downlink user data corresponding to at least a second transport block, the second downlink user data transmitted in the second TTI in the third and fourth set of resources, wherein the first portion of the second downlink user data is arranged to be demodulated based on the first DMRS, and wherein the second portion of the second downlink user data is arranged to be demodulated based on the third DMRS. transmitting, to a user equipment, a first resource assignment in a first transmission time interval, TTI, wherein the first resource assignment defines a first set of resources for receiving a first portion of a first downlink user data in the first TTI, and wherein the first resource assignment defines a second set of resources for receiving a second portion of the first downlink user data in the first TTI, and wherein the second set of resources are configured for Downlink Control Information and are used instead for downlink user data, and the second set of resources do not overlap with the first set of resources, wherein the first set of resources defines a resource location of a first DMRS associated with the first portion of the first downlink user data, and wherein the second set of resources defines a resource location of a second DMRS associated with the second portion of the first downlink user data; transmitting, to the user equipment, the first downlink user data corresponding to at least a first transport block in the first TTI in the first and second set of resources, wherein the first portion of the first downlink user data is arranged to be demodulated based on the first DMRS, and wherein the second portion of the first downlink user data is arranged to be demodulated based on the second DMRS; transmitting, to the user equipment, a second resource assignment in a second TTI, wherein the second resource assignment defines a third set of resources for receiving a first portion of a second downlink user data in the second TTI, wherein the first and third set of resources are configured for downlink user data, wherein the second resource assignment also defines a fourth set of resources for receiving a second portion of the second downlink user data in the second TTI, wherein the fourth set of resources is configured for Downlink Control Information and used instead for downlink user data, and the fourth set of resources do not overlap with the third set of resources, wherein the second resource assignment defines a resource location of a third DMRS associated with the second portion of the second downlink user data in the fourth set of resources, transmitting, to the user equipment, the second downlink user data corresponding to at least a second transport block, the second downlink user data transmitted in the second TTI in the third and fourth set of resources, wherein the first portion of the second downlink user data is arranged to be demodulated based on the first DMRS, and wherein the second portion of the second downlink user data is arranged to be demodulated based on the third DMRS.
