Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). In some examples, the UE may identify an initialization and refresh (IR) packet at the radio link control (RLC) layer based the size of the IR packet, where the IR packet comprises a larger ciphered PDU size than a compressed RoHC packet. Accordingly, once the UE identifies the received packet as an IR packet, the UE may attempt to decipher the IR packet using one or more HFN offset values. In one example, the UE may determine whether the IR packet is deciphered correctly based on cyclic redundancy check (CRC) value of the deciphered IR packet. As a result, the present disclosure allows the UE to re-synchronize with the transmitting device by at least one of incrementing or decrementing an HFN value at the receiving device.

Abstract: The present disclosure describes a method and an apparatus for managing security mode command (SMC) integrity failures at a user equipment (UE). For example, a method is provided for managing SMC integrity failures which receives a SMC message at the UE from a network entity. A message authentication code for data integrity (MAC-I) failure based at least on a mismatch of a security parameter at the UE may be detected at the UE. Moreover, a corrective action may be performed at the UE in response to the detection of the MAC-I failure at the UE.

Abstract: Methods, systems, apparatuses, and devices are described for transmitting a measurement report during wireless communications. When, for example, a low-power period (e.g., CDRX OFF period) is scheduled to begin during a time defined by a measurement event timer (TTT timer), a UE may modify the low-power period. The low-power period may be modified based, at least in part on determining the low-power period of the UE will begin during a time defined by a measurement event timer, a duration of the measurement event timer, and a duration of the low-power period. Modifying the low-power period may include delaying the start of the low-power state until after transmission of the MR associated with the measurement event timer or skipping the low-power period altogether. The UE may transmit the MR based, at least in part, on the modification.

Abstract: Certain aspects of the present disclosure provide techniques for defending against false semi-persistent scheduling (SPS) activation detection and/or missed SPS release. According to certain aspects, a user equipment (UE) may detect one or more conditions for a semi-persistent scheduling (SPS) activation or release are met based on a downlink transmission, generate one or more metrics related to downlink transmission, and determine a valid SPS activation or release has occurred if the one or more metrics satisfy one or more criteria. According to certain aspects, a UE may determine a valid semi-persistent scheduling (SPS) activation has occurred, detect a number of PDSCH CRC failures, and implicitly declare an SPS release based on the detection.

Abstract: Process for the manufacture of a cyclic diester of an alpha-hydroxyacid comprising heating the alpha-hydroxyacid at a temperature from 100 to 250° C. in the presence of at least one polyol and of at least one catalyst selected from the group consisting carboxylates and alkoxides of Ti, Zr, Al and Sn.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing random access channel (RACH) procedures with a base station. For example, certain aspects provide methods and apparatus for performing RACH procedures when a user equipment moves out of range from the base station (e.g., for RACH procedure success). One method includes attempting a RACH procedure with a first base station, determining the UE is out of range from the first base station for RACH procedure success, and, upon determining the UE is out of range from the first base station for RACH procedure success, reattempting the RACH procedure with the first base station or a second base station.

Abstract: A conveyor device has a sequence of two vibrating screens vertically separated (d) from each other and supplying an alignment bowl, to eliminate chips and residue from nuclear fuel pellets stored in bulk in a boat and to align them in order to fill fuel rods. Due to these two screens, pellets are set aside and turned over, and chips are efficiently separated in a pot, without any congestion of the system.

Abstract: Aspects generally relate to wireless communications and, more particularly, to methods, systems and apparatus for timing synchronization during a wireless uplink random access procedure. For example, certain aspects relate to a technique for receiving first timing advance information associated with uplink wireless communications with a base station (BS), transmitting a random access connection request message to the BS, receiving a random access response from the BS while the first timing advance information is within a valid time period, the random access response comprising second timing advance information associated with uplink wireless communications with the base station, determining, after receiving the random access response, that the valid time period for the first timing advance information has expired, and utilizing the second timing advance information for uplink communications with the BS after determining that the valid time period for the first timing advance information has expired.

Abstract: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for paging during Long Term Evolution (LTE) discontinuous reception (DRX) operations. Aspects generally include determining whether one or more paging occasions from a base station (BS) occur while a receiver of an apparatus is in an active state based on a discontinuous reception (DRX) cycle, adjusting a period that the receiver is in the active state during the DRX cycle if at least one paging occasion does not occur while the receiver is in the active state, and monitoring for at least one paging occasion occurring while the receiver is in the active state during the adjusted period.
