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.
