    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: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit an announcement information block (MB) in a downlink shared data channel (e.g., PDSCH), wherein the AIB contains information useable by a UE in determining the location of system information in the downlink shared data channel. The UE can thus determine the location of and decode system information without having to decode a downlink control channel (e.g., PDCCH). This may be important for certain classes of devices, such as link budget limited devices, which have issues in decoding the downlink control channel. Improved paging scheduling techniques are also disclosed which more efficiently use PDCCH paging resources.

    Abstract: A communications system may include a user equipment (UE) device that communicates with a network. The UE may gather first contextual information about usage of the UE device, may receive second contextual information about usage of the network, and may receive third contextual information about usage of additional UE devices. The UE may run an application that requests wireless data transfer. The UE may train a learning model based on the contextual information. The UE may make a network connectivity decision based on the contextual information, the learning model, and a data sensitivity of the application. Once the connectivity decision is made, signals may be conveyed to implement the decision. Performing the connectivity decision on the UE instead of the network may allow the UE and the network to take full advantage of contextual learning in different use cases to optimize performance of both the UE and the network.

    Abstract: A network may include user equipment (UE) devices and a base station that communicates using a control unit (CU) and a data unit (DU). A primary UE may duplicate the DU and a subset of control functions of the CU. When the DU on the primary UE is active, the base station and primary UE may effectuate a split or bearer duplication of the DU at the RLC/PDCP/MAC layer between the primary UE and the base station. Data may be concurrently routed data through the primary UE using inter-UE links and direct cellular telephone links to the base station. When the subset of the control functions of the CU are active on the primary UE, the device may perform RRC functions, MAC control functions, RLC control functions, or other control functions to generate information for use by the base station in updating communications.
