Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine a decompression failure associated with a header of a received packet and a first real-time transport protocol (RTP) sequence number (SN) interpretation window. In some aspects, the wireless communication device may perform a decompression of the header of the received packet using a second RTP SN interpretation window. The second RTP SN interpretation window may be selected based on at least one of one or more values for the first RTP SN interpretation window or a size of the first RTP SN interpretation window.

Abstract: Techniques are described for wireless communication. One method includes identifying a decoding status of one or more physical layer packets before inactivity on a secondary component carrier (SCC) in a shared radio frequency spectrum band; initiating an SCC reordering timer, wherein the SCC reordering timer is initiated when the decoding status of the one or more physical layer packets is identified as unsuccessful; and triggering a transmission, to a base station, of a radio link control (RLC) status report upon expiration of the SCC reordering timer. The RLC status report is transmitted before expiration of a RLC reordering timer initiated when the decoding status of the one or more physical layer packets is identified as unsuccessful. In some examples, the method may include resetting the SCC reordering timer when one or more additional physical layer packets are received on the SCC.

Abstract translation: 技术描述为无线通信。 一种方法包括在共享射频频带中的次分量载波（SCC）上识别不活动之前的一个或多个物理层分组的解码状态; 启动SCC重新排序定时器，其中当所述一个或多个物理层分组的解码状态被识别为不成功时，启动所述SCC重新排序定时器; 以及在SCC重新排序定时器期满时触发无线电链路控制（RLC）状态报告给基站的传输。 当一个或多个物理层分组的解码状态被识别为不成功时，RLC状态报告在RLC重排序定时器期满前被发送。 在一些示例中，该方法可以包括在SCC上接收到一个或多个附加物理层分组时重置SCC重新排序定时器。

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a stream of RTP data packets over a wireless channel and applies ROHC decompression to decode the packets. Upon a failure of ROHC decompression, the apparatus identifies the RTP sequence number (SN), RTP Timestamp (TS), and PDCP receive time (RT) of a prior successfully decoded packet, and the PDCP SN and PDCP RT of the failed packets. Using the identified information, the apparatus estimates the RTP SN and RTP TS of each of the failed packets. The apparatus decodes the packets using the estimated information.
