Intelligent resource assignment to increase throughput in multiple input multiple output (mimo) and carrier aggregation (ca) capable devices

An apparatus for wireless communications, comprising:

• means for communicating with a base station (BS) on multiple component carriers (CCs) through multiple radio frequency (RF) chains, wherein each of the multiple CCs are assigned a number of RF chains among the multiple RF chains;
• means for tentatively switching one or more first RF chains, not assigned to a first CC of the multiple CCs, to the first CC for evaluating a rank of the first CC;
• means for determining that the first CC has a higher rank indication (RI) with the one or more RF chains;
• means for evaluating one or more performance factors, in conjunction with the higher rank;
• and
• means for additionally assigning one or more second RF chains to the first CC for communicating with the BS, based on the evaluation.

A non-transitory computer readable medium having instructions stored thereon for performing a method comprising:

• communicating with a base station (BS) on multiple component carriers (CCs) through multiple radio frequency (RF) chains, wherein each of the multiple CCs are assigned a number of RF chains among the multiple RF chains;
• tentatively switching one or more first RF chains, not assigned to a first CC of the multiple CCs, to the first CC for evaluating a rank of the first CC;
• determining that the first CC has a higher rank indication (RI) with the one or more RF chains;
• evaluating one or more performance factors, in conjunction with the higher rank;
• and
• additionally assigning one or more second RF chains to the first CC for communicating with the BS, based on the evaluation.
