A user equipment (UE) device including an antenna, a memory, an RF circuitry commutatively coupled to the antenna, and a processor configured to perform operations is described. In an exemplary embodiment, the operations include receiving the one or more pre-configured grant (pre-CG) configurations for an RRC_INACTIVE state from a network node. The one or more pre-CG configurations are for an initial data transmission when the UE is in the RRC_INACTIVE state. The operations also include performing, while the UE is in the RRC_INACTIVE state, the initial data transmission using a pre-CG resource based on the received one or more pre-CG configurations. Each of the one or more pre-CG configurations includes a configuration of the pre-CG resource and one or more conditions to use the pre-CG resource. The one or more conditions to use the pre-CG resource include one or more of an access type, a transmission priority, a mapped Logical Channel (LCH)/Dedicated Radio Bearer (DRB)/Quality of Service (QoS) flow, and a valid timing advance (TA).

Methods and apparatus for inactive state initial uplink transmission using pre-configured grant at a user equipment in wireless communication

A method and apparatus of a device that communicates data between a user equipment (UE) device and a base station when the user equipment is in the inactive state is described. In some embodiments, the last serving base station of the UE and the new base station of the UE coordinate with each other to complete the transfer of data while the UE is in the inactive state.

Context fetch procedure for inactive direct data transmission

A method and apparatus of a device that determines an occurrence of the DL SPS or the UL CG to determine a periodicity of a packet generation is described. In an exemplary embodiment, the method receives a configuration for a downlink (DL) Semi-Persistent Scheduling (SPS) or an uplink (UL) Configured Grant (CG). The configuration includes an indication of non-integer periodicity of the DL SPS or the UL CG. Additionally, the method determines an occurrence of the DL SPS or the UL CG based on the received configuration for the DL SPS or the UL CG to determine a periodicity of a packet generation. Thereafter, the method transmits or receives data based on the configuration for the DL SPS or the UL CG.

Methods and apparatus for support of data transmission traffic with non-integer periodicity in wireless communication

Methods and systems are disclosed to configure different paging occasions for enhanced UEs that support, and for legacy UEs that do not support, the enhanced feature of the paging early indication (PEI) in paging procedure for 5G/LTE networks. Different paging occasions for the enhanced and legacy UEs may be configured by providing separate paging occasion parameters for the enhanced and legacy UEs. The network may use the separate paging parameters to design the PEI to save signaling overhead. The network may reuse paging format for the paging PDCCH to serve as the PEI that is transmitted in advance of the paging occasions for the enhanced UEs, or may keep legacy paging PDCCH at its current locations to serve as the PEI for the enhanced UEs. A scheduling offset may be configured to separate in time the paging PDCCH serving as the PEI and the paging PDSCH containing the paging message.

Methods for flexible configuration of paging occasions

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.

Technologies for NR coverage enhancement

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.
