Abstract

Apparatuses, methods, and systems are disclosed for reporting power headroom (“PH”) information. One apparatus includes a transceiver that communicates with a base unit using a first uplink carrier and a second uplink carrier concurrently, first uplink carrier having a longer transmission duration unit (“TDU”) length than the second uplink carrier. The apparatus also includes a processor that receives an uplink resource allocation for a first TDU on the first uplink carrier, the first TDU overlapping in time with at least two second TDUs on the second uplink carrier. The processor determines a third TDU on the second uplink carrier, the third TDU comprises at least one of the second TDUs. The processor calculates PH information for the second uplink carrier associated with the third TDU and reports, via the transceiver, the PH information in an uplink transmission on the first TDU.

Claims26

Dependent claims

A method of a UE comprising:

communicating with a base unit using a first uplink carrier and a second uplink carrier concurrently, the first uplink carrier being configured with a first subcarrier spacing (“SCS”) and the second uplink carrier being configured with a second SCS, wherein the first SCS is smaller than the second SCS;
receiving an uplink resource allocation for a first slot on the first uplink carrier wherein the first slot fully overlaps in time with at least two second slots on the second uplink carrier;
receiving an uplink resource allocation for at least one of the at least two second slots on the second uplink carrier that are fully overlapped by the first slot on the first uplink carrier;
calculating power headroom (“PH”) information for the second uplink carrier for a first physical uplink shared channel (“PUSCH”) scheduled on a first of the at least two second slots that are fully overlapped by the first slot on the first uplink carrier;
and
reporting the PH information in an uplink transmission on the first slot on the first uplink carrier.
