Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines a failure to receive an MSI for a first MSP. The UE attempts to decode one or more subframes in the first MSP. The UE detects an occurrence of an MSP abort decoding event. The UE determines that the first MSP does not include any subframe that carries MBMS data of an MBMS segment based on the detection of the MSP abort decoding events. The UE aborts the attempt to decode the one or more subframes.

Abstract: A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station.

Abstract translation: 用户设备（UE）可以在用于上行链路（UL）传输的缓冲器中具有数据。 UE可以发送指示数据量的缓冲器状态报告（BSR）。 BSR可能会失败，或者基站可能无法为数据传输提供足够的资源。 BSR故障条件可以基于数据的无线电链路控制（RLC）操作模式。 例如，数据可以是用于确认模式（AM）DL传输的确认（ACK）。 在这种情况下，UE可以发起BSR重传（Retx-BSR）定时器并且确定是否已经接收到任何重复的传输。 数据也可以与未确认模式（UM）相关联，并且BSR故障条件可以包括等待小于Retx-BSR时间间隔的时间间隔。 当满足BSR故障条件时，UE可以向基站发送调度请求。
