Wireless communication systems and methods related to Radio Link Control (RLC) status reporting are provided. A wireless communication device receives one or more radio link control (RLC) packet data units (PDUs) of a sequence of RLC PDUs. The wireless communication device determines missing RLC data PDUs in the sequence of RLC PDUs based on the received one or more RLC PDUs. The wireless communication device receives a first uplink (UL) grant. The wireless communication device transmits a first RLC status report including an indication of a first subset of the missing RLC PDUs less than all the missing RLC PDUs, the indication of the first subset of missing PDUs being based on a size of the first UL grant. The wireless communication device modifies a RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.
