Abstract: A wireless device (300, 400), e.g., a wireless communication device (e.g., a UE) or a network node (e.g., an eNB) having a Medium Access Control (MAC) layer (410) and a physical (PHY) layer (430) configured to send/resend transmissions is presented herein. The MAC layer (410) sends transmissions to the PHY layer (430) for transmitting, by the PHY layer (430), to a remote wireless device (300, 400). The PHY layer (430) receives the transmission from the MAC layer (410), and attempts to send the transmission. The PHY layer (430) further indicates to the MAC layer (410) whether the attempt to send the transmission, by the PHY layer (430), was successful. Responsive to the indication, the MAC layer (410) determines whether the attempt, by the PHY layer (430), to send the transmission was successful. The MAC layer (410) then selectively indicates to the PHY layer (430) whether to attempt to resend the transmission responsive to the determination.

Abstract: An application update system performs staged rollouts to push new versions or features of applications to users quickly and with minimal negative impact to the users. The application update system allocates users of an application to populations. The populations specify a subset of users to receive a feature update for the application.

For example, when the feature update performs successfully, the application update system allocates additional users to receive the feature update. When all users of the application have received the feature update, the staged rollout is designated as complete.

Abstract: Various aspects of the disclosure relate to encoding information and decoding information. In some aspects, the disclosure relates to an encoder and a decoder for Polar codes with HARQ.

In some aspects, CRC bits for a first transmission may be split between a first subset of bits and a second subset of bits. In this case, the second subset of bits and the associated CRC bits may be used for a second transmission (e.g., a retransmission).
