Abstract: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.

Abstract: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: Systems and methods for performing measurements of one or more cells during an small data transmission (SDT) procedure between a user equipment (UE) and a network when the UE is in a radio resource control (RRC) INACTIVE state are described herein. Beam and/or cell measurements taken during an SDT measurement period of the SDT procedure may be used to determine one or more respective cell qualities, among other possibilities. Beginnings and endings of the SDT measurement period, and the manner (timing) for taking measurements within the SDT measurement period, are also described. The cell qualities so determined can then be used to monitor, during the SDT measurement period, for a measurement event, which causes the UE to send a measurement report to the network having data determined using those cell qualities, and/or to send messaging intended to induce the network to change the RRC state of the UE.

Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network can operate to communicate in a UE to UE (U2U) relay path through a first relay UE with another UE as a source or destination UE according to a direct communication request initiating from the source UE. The UE can further perform a U2U relay reselection to a second relay UE in response to a trigger condition, either as a source UE or a destination UE.

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: 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.
