1. User Equipment (UE) comprising hardware processing circuitry to:
- generate a delayed buffer status report (D-BSR) medium-access control (MAC) control element for transmission to an enhanced Node B (eNB) with a last-scheduled uplink grant, the D-BSR MAC control element to include at least an indicator of a delay value; and
receive a delayed grant for uplink bandwidth in response to transmission of the D-BSR MAC control element, the grant being received from the eNB no sooner than the delay value and including a bandwidth allocation.

Abstract
Embodiments of user equipment and methods for reducing delay in a radio-access network (RAN) are generally described herein. Embodiments disclosed herein provide enhancements that may be applicable to a 3GPP LTE RAN for reducing delay that may be particularly beneficial for real-time over-the-top (OTT) applications. Some embodiments provide for an uplink delayed buffer status report. Some embodiments provide for a downlink congestion and buffer report. Some embodiments provide for traffic characteristic based inter-UE prioritization.
