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: Techniques discussed herein can facilitate integrated sensing and communication (ISC), where a wireless network is used for both sensing and for wireless communications. One example aspect is sensing function entity configured to receive a sensing service request from an access and mobility function (AMF) entity, where the sensing service request is received by an access and mobility function/sensing function (AMF/SF) interface. The SF entity is further configured to transmit, by the AMF/SF interface, a sensing service response to the AMF entity and subsequently receive sensing data associated with the sensing service response, where the sensing data is received by a base station/sensing function (BS/SF) interface. The SF entity is further configured to process the sensing data, and transmit the sensing response after processing the sensing data.

Abstract: MBS key distribution includes processing group information associated with an MB session context received from an AF. At least a portion of the group information comprises a TMGI. A plurality of session join requests received from a plurality of UEs are processed. Each of the plurality of session join requests include the TMGE and are associated with the MB session context. A request associated with the MB session context for transmission to an MB-SMF is encoded. A response associated with the MB session context received from the MB-SMF is processed. The response includes a key derived for each of a portion of the plurality of UEs using a UE ID and the TMGI. A DL NAS message and an N2 message are encoded for the plurality of UEs and a base station, respectively. The DL NAS message and the N2 message include the derived key.

Abstract: An example technique for security key derivation in a wireless system includes: receiving a radio resource control (RRC) suspend message from a first node, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value, entering a RRC inactive state, deriving a first node key based on the first NCC value, generating a first uplink message for transmission in the RRC inactive state based on the first node key, and transmitting the first uplink message to a node while in the RRC inactive state.

Abstract: Techniques discussed herein can facilitate improved security establishment procedures for Vehicle to Everything (V2X) direct connections. Various embodiments are employable at or comprise User Equipment, and can initiate and/or receive V2X security establishment connections wherein a receiving UE can reject the connection based on the initiating UE's capabilities/policy and/or the initiating UE can make the final decision regarding the connection based at least on receiving security policy and capability information from the receiving UE.

Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

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: Systems and methods provide packet data convergence protocol (PDCP) user plane (UP) integrity protection (IP) for a user equipments (UE) and radio access network (RAN) nodes operating in Evolved Universal Terrestrial Radio Access-New Radio dual connectivity (EN-DC). In an attach procedure, a UE may indicate a UE security capability for support of relay node (RN) PDCP UP IP used in LTE. Based on the LIE security capability, a master e Node B (MeNB) security capability, and a secondary g Node B (SgNB) security capability, the MeNB may determine whether to use UP IP between the UE and the MeNB, the UE and the SgNB, and/or in a split bearer between the MeNB and the SgNB.

The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving PDSCH and PDCCH channels. The UE may use the configuration parameters to receive PDSCH and PCCCH that are coverage enhanced using time repetitions and frequency hopping. 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.
