Summary: | PROBLEM TO BE SOLVED: To provide user equipment and methods for reducing delay in a radio-access network (RAN).SOLUTION: User Equipment (UE) generates 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, and receives a delayed grant for uplink bandwidth in response to the transmission of the D-BSR MAC control element. The D-BSR MAC control element includes at least an indicator of a delay value. The grant is received from the eNB no sooner than the elapse of the delay value, and includes a bandwidth allocation.SELECTED DRAWING: Figure 1
【課題】無線アクセスネットワーク(RAN)において遅延を低減するためのユーザ機器および方法を提供するする。【解決手段】ユーザ機器(UE)は、最後にスケジューリングされたアップリンク認可で拡張型ノードB(eNB)へ送信するために遅延バッファ状況報告(D−BSR)媒体アクセス制御(MAC)制御要素を生成し、D−BSR MAC制御要素の送信に応答してアップリンク帯域幅の遅延させられた認可を受信する。D−BSR MAC制御要素は、遅延値のインジケータを少なくとも含み、前記認可は、前記遅延値の経過後すぐに前記eNBから受信され、帯域幅割り当てを含む。【選択図】図1 |
