Enhanced power headroom reporting in wireless communication networks
First Claim
1. A method in a wireless communication device, the method comprising:
- determining a first configured maximum transmit power (PCMAX) value corresponding to a first set of resource blocks (RBs) having a first set of subcarriers in a carrier for a subframe, the first set of RBs including less than a complete set of RBs constituting the carrier;
determining a second PCMAX value corresponding to a second set of RBs having a second set of subcarriers in the same carrier for the subframe, the first and second sets of RBs containing RBs of a common type, the second set of RBs different from the first set of RBs and the second set of RBs including less than the complete set of RBs constituting the carrier;
determining a difference between the first PCMAX value corresponding to the first set of RBs having the first set of subcarriers in the carrier for the subframe and the second PCMAX value corresponding to the second set of RBs having the second set of subcarriers in the same carrier for the subframe; and
sending a composite report for the subframe including at least the first PCMAX value corresponding to the first set of RBs having the first set of subcarriers in the carrier for the subframe and the second PCMAX value corresponding to the second set of RBs having the second set of subcarriers in the same carrier for the subframe to a base station in response to determining that the difference between the first PCMAX value and the second PCMAX value exceeds a threshold.

Abstract
A method in a wireless communication device includes determining a first configured maximum transmit power (PCMAX) value corresponding to a first set of resource blocks (RBs) in a carrier for a subframe, wherein the first set of RBs includes less than a complete set of RBs constituting the carrier, determining a second PCMAX value corresponding to a second set of RBs in the carrier for the subframe, wherein the first and second sets of RBs are of a common type and the second set of RBs is different from the first set of RBs and the second set of RBs includes less than the complete set of RBs constituting the carrier. A composite report for the subframe including the first and second PCMAX values is then sent to a base station.
