Abstract: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A user equipment (UE) may receive, from a base station, information indicating that a coverage enhancement mode is supported. The UE may determine whether to enter the coverage enhancement mode based on a downlink signal synchronization block (DL SSB). In response to determining to enter the coverage enhancement mode, the UE may transmit a reserved preamble to the base station to initiate random access for the coverage enhancement mode.

Abstract: Techniques to protect a subscriber identity, by encrypting a subscription permanent identifier (SUPI) to form one-time use subscription concealed identifiers (SUCIs) using a set of one-time ephemeral asymmetric keys, generated by a user equipment (UE), and network provided keys are disclosed. Encryption of the SUPI to form the SUCIs can mitigate snooping by rogue network entities, such as fake base stations. The UE is restricted from providing the unencrypted SUPI over an unauthenticated connection to a network entity. In some instances, the UE uses a trusted symmetric fallback encryption key KFB or trusted asymmetric fallback public key PKFB to verify messages from an unauthenticated network entity and/or to encrypt the SUPI to form a fallback SUCIFB for communication of messages with the unauthenticated network entity.

Abstract: This disclosure relates to techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals for multi-transmission-reception-point operation in a wireless communication system. A wireless device may establish wireless links with multiple transmission-reception-points of a cellular network. The wireless device may receive downlink control information. The wireless device may determine a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information. Signals received according to the quasi-co-located assumption for aperiodic channel state information reference signals may be buffered by the wireless device if a scheduling offset for the downlink control information is below a scheduling offset threshold.

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.
