A method in a network node participating in a cooperative multi-point, CoMP, environment, comprising: transmitting a pilot pattern; transmitting control information to a user equipment, UE, the control information associating one or more first transmit layers with the pilot pattern, the first transmit layers having predefined modulation and coding and being multiplexed in a time-frequency resource space in at least one of: a time domain, a frequency domain, a code domain, a power domain, and a space domain, wherein the first transmit layers are multiplexed in a first transmission tier, receiving, from the UE, feedback information, wherein feedback information comprises at least one of: information identifying first transmit layers the UE was able to jointly detect in the first transmission tier; and information identifying channel quality indicators, CQIs, for second transmit layers having adaptive modulation and coding and being multiplexed in a second transmission tier; wherein the first and second transmission tiers are in respective time frequency resources that at least partially overlap and wherein the first transmission tier uses a predefined modulation and coding and the second transmission tier uses adaptive modulation and coding; and scheduling data transmission for the UE based on the feedback information. transmitting a pilot pattern; transmitting control information to a user equipment, UE, the control information associating one or more first transmit layers with the pilot pattern, the first transmit layers having predefined modulation and coding and being multiplexed in a time-frequency resource space in at least one of: a time domain, a frequency domain, a code domain, a power domain, and a space domain, wherein the first transmit layers are multiplexed in a first transmission tier, receiving, from the UE, feedback information, wherein feedback information comprises at least one of: information identifying first transmit layers the UE was able to jointly detect in the first transmission tier; and information identifying channel quality indicators, CQIs, for second transmit layers having adaptive modulation and coding and being multiplexed in a second transmission tier; wherein the first and second transmission tiers are in respective time frequency resources that at least partially overlap and wherein the first transmission tier uses a predefined modulation and coding and the second transmission tier uses adaptive modulation and coding; and scheduling data transmission for the UE based on the feedback information. information identifying first transmit layers the UE was able to jointly detect in the first transmission tier; and information identifying channel quality indicators, CQIs, for second transmit layers having adaptive modulation and coding and being multiplexed in a second transmission tier; wherein the first and second transmission tiers are in respective time frequency resources that at least partially overlap and wherein the first transmission tier uses a predefined modulation and coding and the second transmission tier uses adaptive modulation and coding; and scheduling data transmission for the UE based on the feedback information.
