Abstract
A method and system to signal transmission layers or dedicated reference signal ports to be used in a multiple input multiple output system, the method including providing a downlink control signal containing information for transmission layers or dedicated reference signal ports utilized, the dedicated reference signal ports being associated with the transmission layers; and using the information to demodulate data on each transmission layer.

1-33. (canceled)
An eNodeB of a multiple input multiple output ‘MIMO’ system, comprising:
- a processor configured to execute instructions that cause transmission of downlink control information ‘DCI’ that contains information regarding a number of transport blocks to be utilized by a user equipment ‘UE’ and an index value;
- wherein the number of transport blocks and the index value together indicate to the UE which layer combination or associated combination of dedicated reference ports to utilize.
A non-transitory computer-readable medium storing instructions which, when executed by a processor of an eNodeB, cause transmission of downlink control information ‘DCI’ that contains information regarding a number of transport blocks to be utilized by a user equipment ‘UE’ and an index value;
- wherein the number of transport blocks and the index value together indicate to the UE which layer combination or associated combination of dedicated reference ports to utilize.
A user equipment ‘UE’ comprising:
- a processor configured to execute instructions that cause receipt of downlink control information ‘DCI’ that contains information regarding a number of transport blocks to be utilized and an index value;
- wherein the number of transport blocks and the index value together indicate to the UE which layer combination or associated combination of dedicated reference ports to utilize.
A method at an eNodeB, comprising:
- transmitting to a user equipment ‘UE’ a downlink control information ‘DCI’ that contains information regarding a number of transport blocks to be utilized by the UE and an index value;
- wherein the number of transport blocks and the index value together indicate to the UE which layer combination or associated combination of dedicated reference ports to utilize.
A method at a user equipment ‘UE’, comprising:
- receiving, from an eNodeB, a downlink control information ‘DCI’ that contains information regarding a number of transport blocks to be utilized and an index value;
- wherein the number of transport blocks and the index value together indicate to the UE which layer combination or associated combination of dedicated reference ports to utilize.
