Abstract: Technology is disclosed for a vehicle-capable user equipment (vUE) operable for sensing-based distributed scheduling 5 of event-based mission critical (MC) vehicle-to everything (V2X) traffic. The vUE can sense sidelink control information (SCI) for semi persistent scheduling (SPS) resource selection from one or more SCI messages received in one or more physical sidelink control channels (PSCCHs) from one or more neighboring vUEs. The vUE can identify: a number of MC resources to transmit event10 based MC data with a selected number of repetitions within a latency budget, wherein the MC resources include one or more of MC-SCI or MC data with the selected number of repetitions; and a number of available resources to transmit event-based MC data within the latency budget. The vUE can select revocable resources from one or more scheduled low-priority resources based on the sensed SCI for SPS resource selection.

Abstract: A base station can obtain channel quality conditions for mobile devices in a scheduling interval and identify a channel quality, a target transmission scheme, and a transmission power level for each of the mobile devices. The base station can assign a unique orthogonal CDMA code and can force the mobile devices to transmit K repeated bursts of uplink data such that each of the mobile devices has a rotated phase shift based on the unique orthogonal CDMA code assigned to each of the mobile devices with each of the mobile devices multiplexed on a same physical channel using an overlaid CDMA operation. The base station can process K repeated bursts that are multiplexed on the same physical channel using the overlaid CDMA operation. The base station can separate the mobile devices according to the unique orthogonal CDMA code and use IQ accumulation according to combine the K repeated bursts.
