    Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including generating a layer-2 (L2) header block for a medium access control (MAC) subprotocol data unit (subPDU), the MAC subPDU including a MAC service data unit (SDU) that includes an internet protocol (IP) packet; ciphering at least a portion of the L2 header block; and assembling a transport block that includes the ciphered portion of the L2 header block in the MAC subPDU.

    Abstract: An apparatus to be implemented in a user equipment (UE), the apparatus comprising hardware circuitry to activate a timer for transmitting a measurement report to a base station; output a filtered signal value from a measured signal using a first parameter; determine a trend in signal quality based on the first filtered signal value and a second filtered signal value based on a second parameter; or some processing of the values either from the first filter or from the received signal; and determine whether to deactivate the timer based on the trend in signal quality. The filtered signal can be generated using a first layer 3 filter using network-configured parameters and a second layer 3 filter using proprietary parameters. Processing of the values can also be done using proprietary parameters and techniques.

    IPC: H04W36/00

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for support mobility in a wireless network for user equipments (UEs) with varying capabilities. A UE can receive a first system information from a serving base station, where the first system information includes a UE capability condition associated with a neighbor base station, and determine whether a UE capability meets the UE capability condition associated with the neighbor base station. When the UE capability condition is met, the UE can determine whether a first measurement of a first reference signal received from the serving base station and a second measurement of a second reference signal received from the neighbor base station satisfy a threshold condition. When the threshold condition is met, the UE can obtain a second system information from the neighbor base station, indicating the UE has performed handover to the neighbor base station.
