    Abstract: A user equipment (UE) establishes a first type of connection to a first public land mobile network (PLMN), the first type of connection having a first non-access stratum (NAS) Count pair corresponding to a first NAS security context associated with the first PLMN, establishes a second type of connection to a second PLMN, wherein a previous second type of connection was established with the first PLMN, wherein the previous second type of connection has a second NAS Count pair corresponding to the first NAS security context, wherein the second type of connection has a third NAS Count pair corresponding to a second NAS security context associated with the second PLMN and deregisters the previous second type of connection with the first PLMN to reset the second NAS count pair at the first PLMN.

    Abstract: An example technique for security key derivation in a wireless system includes: sending a radio resource control (RRC) suspend message from a first node, to a first user device, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value; releasing access stratum (AS) resources associated with the first user device; deriving a first node key based on the first NCC value; receiving a first uplink message from the first user device without allocating AS resources to the first user device; and unscrambling the first uplink message based on the first NCC value.

    Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving the PDSCH and PDCCH channels, when transmitting the PUSCH and PUCCH channel, and when transmitting PUSCH Msg3 during random access. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

    Abstract: The exemplary embodiments relate to a computer-readable storage medium, a device, an integrated circuit and a method that perform operations related to a first user equipment (UE) configured with a side link (SL) connection with a second UE. The operations include generating an SL counter check request including at least a first count for data transmissions from the first UE to the second UE as determined by the first UE. The operations further include transmitting the request to the second UE and receiving a counter check response to the request, the response comprising at least a second count for data transmissions from the first UE to the second UE as determined by the second UE. The operations further include determining a first difference between the first count and the second count and, when the first difference exceeds a threshold, releasing the SL connection with the second UE.

    Abstract: A user equipment (UE) is configured to join a multicast broadcast service (MBS) session. The UE sends, to a network function, a protocol data unit (PDU) modification request comprising a request to join a multicast broadcast service (MBS) session, generates a first key (K MBS-UE), receives a PDU session modification complete message comprising an encrypted second key (K MBS) and a key identification (KID) corresponding to the K MBS and decrypts the KMBS using the K MBS-UE.

    Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential that was generated for a procedure between the UE and a network. The UE then generates an identifier corresponding to the first credential and generates a message authentication code based on the first credential and a count, wherein the count is associated with an identifier of an edge network client running on the UE. The UE then transmits an application registration request message to a server associated with an edge data network, the application registration request message including the count, the message authentication code, the identifier corresponding to the first credential, and a public land mobile network identifier (PLMN ID) of the network. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.
