Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform flexible acknowledgement. A UE may determine whether or not to solicit feedback (e.g., HARQ ACK/NACK) for one or more groupcast transmissions. The determination may be based on factors such as a remaining time to perform the transmission and the amount of time needed to perform the transmission with and without allowing time to receive and process feedback.

Abstract: Techniques, described herein, include solutions for enabling inter-user equipment (UE) coordination (IUC) using media access control (MAC) control elements (CE). A first UE may send an IUC request to a second UE, and the second UE may respond with a MAC CE that includes IUC information. The IUC information may indicated one or more wireless resources that the first UE may use to communicate with the second UE. The IUC information may also include a time-domain validity for wireless resources, which may include one or more durations of time the wireless resources may be used for communication. The first UE may also implement a latency bound during which the second UE is to respond with the IUC information. In some implementations, discontinuous reception (DRX) may be used by the first and second UEs, and DRX active times of the UEs may be modified or configured to facilitate IUC.

Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.

Abstract: A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a C-V2X capable wireless device configured to operate according to a first sidelink mode where communication resources are allocated by a network and a second sidelink mode where communication resources are autonomously allocated by the wireless device. The wireless device detects a change in a coverage scenario associated with the first sidelink mode; performs resource sensing for the second sidelink mode; and based at least in part on detecting the change in the coverage scenario, transmits first communications using the second sidelink mode, wherein resources for transmitting the first communications are allocated based at least in part on the resource sensing.

Abstract: Provided is a method for a user equipment (UE). The method includes determining a mobility state of the UE and performing reference signal measurement in a relaxation mode within at least one cell. The mobility state indicates mobility capability of the UE, and, the at least one cell is determined based on the mobility state.

Abstract: Techniques discussed herein facilitate generation of uplink control information for Enhanced Physical Uplink Control Channel (PUCCH) Format(s) (EPF(s)). One example embodiment employable in a User Equipment (UE) is configured to: determine Hybrid Automatic Repeat reQuest-Acknowledgment (HARQ-ACK) information; generate a PUCCH for a BandWidth Part (BWP) based at least in part on the HARQ-ACK information, wherein the PUCCH has an EPF; determine a PUCCH resource for the PUCCH and a first PRB index for the PUCCH, wherein the PUCCH resource is determined based at least in part on an index of a first Control Channel Element (CCE) of an associated Physical Downlink Control Channel (PDCCH) and a number of CCEs in a Control Resource Set (CORESET) of the associated PDCCH; and map the PUCCH to at least one PUCCH interlace based on the PUCCH resource and the first PRB index for the PUCCH.
