Abstract: Methods, systems, and apparatuses for synchronizing data transmission activity by user equipment (UE). In one aspect, the method comprises determining, by the UE and based on current usage of resources, that alignment of subsequent usage of resources is to be adjusted, generating, by the UE, data that indicates a plurality of activity alignment parameters that are to be adjusted in order to cause the adjusted alignment of subsequent usage of resources, encoding, by the UE, the generated data for transmission to a base station, and transmitting, by the UE, the encoded data to the base station.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

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 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: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to resume a connection. To resume the connection, the UE may transmit a fully protected connection resume message, e.g., which may include protection for a resume cause field.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.
