Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for balancing time resource allocation between cellular vehicle-to-everything (C-V2X) and intelligent transport systems (ITSG5)/dedicated short range communication (DSRC). For example, some embodiments are directed to an electronic device including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to monitor, using the radio front end circuitry, a channel for a time period and determine, based on the monitoring the channel, an average channel occupancy level (COL) of the channel over the time period. The processor circuitry can further be configured to compare the average COL to one or more thresholds and change a resource share of long-term evolution (LTE) cellular vehicle-to-everything (C-V2X) intervals based on the comparison.

Abstract: A user equipment (UE) configured for multi-antenna communication estimates at least one of a rank indicator and a channel quality indicator for device to device (D2D) based on communication data associated with a plurality of packets communicated using D2D communication and without using a dedicated reference signal for D2D communication. The UE may be configured as at least one of a transmitter (Tx) and a receiver (Rx) for vehicle-to-everything (V2X) communication through a sidelink channel.

Abstract: Some embodiments of this disclosure include apparatuses and methods for accessing a communication frequency channel by a first communication system during a first time interval, and accessing the communication frequency channel by a second communication system during a second time interval adjacent to the first time interval. The first communication system communicates using cellular communication techniques, and the second communication system communicates using IEEE 802.11 based communication techniques.
