In one aspect, the invention provides a multi-modal user equipment (UE)
configuration method. In some embodiments, the method includes:
configuring the UE so that it supports a plurality of radio access
technologies (RATs), wherein each of the plurality of RATs is associated
with a predetermined maximum number of layers that the UE may be
instructed by a network node to monitor simultaneously; configuring the
UE so that it is operable to transmit to the network node RAT capability
information identifying the plurality of RATs supported by the UE; and
configuring the UE to monitor simultaneously not more than X layers
associated with one of the plurality of RATs, wherein X is less than the
predetermined maximum number of layers associated with the RAT.
