Abstract: Systems and methods for sidelink transmission. In some embodiments, a method includes: determining, by a User Equipment (UE), a measure of channel congestion, the measure of channel congestion being a channel busy ratio or a channel occupancy ratio; determining, by the UE, a determined contention window size, based on the measure of channel congestion; and waiting, during a first interval of time, without making a sidelink transmission, wherein a length of the first interval of time is based on the determined contention window size.

Abstract: A system and a method are disclosed for synchronization performed by a UE in a coexistence band of a first communication scheme and a second communication scheme. A method includes determining if a base station or another UE synchronized with the base station is detected, in response to determining that neither the base station nor the another UE synchronized with the base station is detected, determining if a first UE that is resending a first synchronization reference signal based on a second synchronization reference signal of the second communication scheme is detected, wherein the first UE includes a modem corresponding to the first communication scheme, and in response to detecting the first UE that is resending the first synchronization reference signal, synchronizing to the first UE.

Abstract: A system and a method are disclosed for improving resource selection schemes is provided. In an embodiment, Scheme 2 resource selection is improved by using a Sidelink Feedback Channel (PSFCH) resources to identify specific instances of conflicts in a periodic reservation of a resource. In an embodiment, Scheme 1 resource selection is improved by allowing a user equipment (UE) to include non-preferred resources in a candidate resource set based on one or more conditions and/or subject to one or more limitations. In an embodiment, condition triggered resource selection assistance is improved by restricting a UE from sending resource selection assistance information unless a second condition is satisfied.

Abstract: A system and a method are disclosed for relaying in wireless communications. In some embodiments, a method includes: receiving, by a first User Equipment (UE), a single first Transport Block including a plurality of Code Block Groups (CBGs); attempting to decode each of the CBGs, by the first UE; and signaling, to a second UE, by the first UE: a successful decoding of a first CBG; and a unsuccessful decoding of a second CBG.

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.

Abstract: A system and a method are disclosed resource selection by a UE in a coexistence band. the method includes obtaining, through a first communication scheme modem, a set of candidate resources for resource selection within a resource selection window, and first sensing information for potential resources for transmission, obtaining, through a second communication scheme modem, resource information corresponding to the second communication scheme, the resource information including second sensing information and future reservations; processing the resource information corresponding to the second communication scheme with the first sensing information; excluding resources, which are identified as occupied based on the processed information, from the set of candidate resources for resource selection for use by the first communication scheme; and selecting a resource for use by first communication scheme from remaining resources within the set of candidate resources after the excluding.

Abstract: Disclosed is a method for long term evolution (LTE) carrier determination by a new radio user equipment (NR UE), including determining whether an LTE carrier includes unused resources for data transmission, in response to determining the LTE carrier includes the unused resources, performing a collision determination, the collision determination being based at least in part on a randomized likelihood that transmissions of the NR UE on the LTE carrier will collide with transmission of one or more other NR UEs on the LTE carrier, and based on the collision determination, performing a transmission delay, the transmission delay occurring during a random back off period duration.

Abstract: A method and a device are provided in which a request for positioning assistance is received from a UE in a dedicated field of sidelink (SL) control information (SCI). A request for assistance in selecting resources for SL-positioning reference signal (PRS) transmission is transmitted to the UE. A set of one or more preferred or non-preferred resources for SL-PRS transmission is received from the UE. Resources for the SL-PRS transmission are selected based on at least the set of one or more preferred or non-preferred resources.

Abstract: A system and a method are disclosed for determining, by a targeted receiving User Equipment (UE), that a corresponding transmitting UE has a future reserved resource block. The receiving UE may perform a Listen Before Talk (LBT) sensing to identify a time period when an unlicensed channel is unoccupied and can be used by the corresponding transmitting UE for the future reserved sidelink transmission. The receiving UE may transmit a reservation signal for the unlicensed channel to the corresponding transmitting UE, during at least a portion of the time period when the unlicensed channel is unoccupied. Further, the receiving UE may, switch, to a receiving mode prior to or at a reserved slot boundary of the future reserved resource block.

Abstract: A system and a method are provided in which a user equipment (UE) obtains a positioning reference signal (PRS) configuration message from an anchor UE based on a basic safety message (BSM) of the anchor UE. The UE receives a sidelink PRS from the anchor UE based on the PRS configuration message, and perform a positioning measurement based on the received PRS.
