Abstract: Methods, systems, and devices for wireless communication are described. The method may include receiving an UL grant for each CC of a plurality of CCs. In an aspect, each UL grant may include a number of transport blocks (TBs) assigned to each CC. The method may further include sorting CCs among the plurality of CCs as a function at least in part based on the number of TB for each of the CCs, and transmitting one or more packet data units (PDUs) using a subset of CCs of the plurality of CCs. In an aspect, the subset of CCs may be based at least in part on the sorting, and any CC of the plurality of CCs in which only medium access control (MAC) padding PDUs would be transmitted may not be included in the subset of CCs.

Abstract: Aspects described herein relate to wireless communications. Protocol data units (PDUs) can be received at a network layer from one or more transmitting nodes using a link associated with each respective transmitting node. One or more missing PDUs can be detected based, at least in part, on sequence numbers of the received PDUs. A timer can be started based on the detection of the one or more missing PDUs. In response to expiration of the timer, and without receiving the one or more missing PDUs before the expiration of the timer, a lower network layer can be notified that the one or more missing PDUs are received to prevent attempted transmitting/retransmitting or other processing of the one or more missing PDUs.
