    Abstract: Systems and methods are disclosed for transmission by a UE in a coexistence band of a first communication scheme and a second communication scheme. A method includes identifying that the UE is operating on a shared carrier; determining whether a beginning of a first communication scheme slot coincides with a beginning of a second communication scheme subframe on the shared carrier; in response to determining that the beginning of the first communication scheme slot coincides with the beginning of the second communication scheme subframe, performing energy detection; and performing a first type of slot transmission based on energy detected for an overlapping subframe of the second communication scheme subframe being less than a first threshold.

    Abstract: A UE apparatus is provided for NR V2X Mode 2 resource selection. The UE apparatus includes a transceiver; and a processor configured to identify a sensing window and a resource selection window, monitor for sidelink control information (SCI) transmitted by neighbor UEs in the sensing window, determine a resource for transmitting data in the resource selection window, and transmit, via the transceiver, data using the determined resource. The sensing window includes a mandated sensing duration for detection of aperiodic traffic prior to transmission by the transceiver.

    Abstract: A method may include sending a contention resolution message for a random access procedure from a user equipment (UE) through a physical uplink channel in a wireless communication network, and sending a repetition of the contention resolution message from the UE through the physical uplink channel. The physical uplink channel may include a physical uplink shared channel (PUSCH). The method may further include selecting a preamble from a first preamble group corresponding to a capability of the UE to send the repetition of the contention resolution message, and sending the preamble from the UE. Selecting the preamble from the first preamble group may include selecting a preamble from a first preamble sub-group corresponding to the capability of the UE to send the repetition of the contention resolution message.
