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.
Claims21
(canceled)
A user equipment (UE), comprising:
- a processor, configured to:
- receive a first downlink control information (DCI),
- wherein the first DCI indicates that a first transmission includes one transport block, and the first DCI comprises a first index value,
- wherein the first DCI indicating that the first transmission includes the one transport block indicates that the UE is to determine one or more dedicated reference signal ports from a first set of dedicated reference signal port combinations associated with single transport block transmission, each dedicated reference signal port combination of the first set of dedicated reference signal port combinations comprising one or more dedicated reference signal ports that are each associated with a corresponding layer,
- determine, based on the first index value, at least a first dedicated reference signal port for the first transmission from the first set of dedicated reference signal port combinations associated with single transport block transmission;
- receive the first transmission comprising the one transport block using at least the first dedicated reference signal port;
- receive a second DCI,
- wherein the second DCI indicates that a second transmission includes two transport blocks, and the second DCI comprises a second index value,
- wherein the second DCI indicating that the second transmission includes the two transport blocks indicates that the UE is to determine one or more dedicated reference signal ports from a second set of dedicated reference signal port combinations associated with two transport block transmission, each dedicated reference signal port combination of the second set of dedicated reference signal port combinations comprising one or more dedicated reference signal ports that are each associated with a corresponding layer,
- determine, based on the second index value, at least a second dedicated reference signal port for the second transmission from the second set of dedicated reference signal port combinations associated with two transport block transmission;
- and
- receive the second transmission comprising the two transport blocks using at least the second dedicated reference signal port.

- receiving a second DCI,
- wherein the second DCI indicates that a second transmission includes two transport blocks, and the second DCI comprises a second index value,
- wherein the second DCI indicating that the second transmission includes the two transport blocks indicates that the UE is to determine one or more dedicated reference signal ports from a second set of dedicated reference signal port combinations associated with two transport block transmission, each dedicated reference signal port combination of the second set of dedicated reference signal port combinations comprising one or more dedicated reference signal ports that are each associated with a corresponding layer,
- determining, based on the second index value, at least a second dedicated reference signal port for the second transmission from the second set of dedicated reference signal port combinations associated with two transport block transmission;
- and
- receiving the second transmission comprising the two transport blocks using at least the second dedicated reference signal port.
8 more elements
A user equipment (UE), comprising:
- a processor, configured to:
- receive a downlink control information (DCI),
- wherein the DCI indicates a number of transport blocks included in a transmission, and the DCI comprises an index value,
- wherein the processor is configured to determine, using the index value, one or more dedicated reference signal ports for the transmission from a first set of dedicated reference signal port combinations associated with single transport block transmission if the DCI indicates a single transport block is included in the transmission, and the processor is configured to determine, using the index value, the one or more dedicated reference signal ports for the transmission from a second set of dedicated reference signal port combinations associated with two transport block transmission if the DCI indicates two transport blocks are included in the transmission;
- and
- receive the transmission comprising the indicated number of transport blocks using the one or more dedicated reference signal ports determined using the index value.
3 more elements
A method in a user equipment (UE), the method comprising:
