    Abstract: Methods and apparatuses are described herein to address issues at the MAC layer resulting from potential Listen-Before-Talk (LBT) failures and delayed transmission. For example, a wireless transmit/receive unit (WTRU) may monitor a plurality of TX resource pools within a sidelink bandwidth part (BWP) for LBT events. The WTRU may cause, based on determining that an LBT failure has occurred, a corrective action associated with a sidelink MAC procedure. The WTRU may determine, based on the LBT failure, that a total number or consecutive number of detected LBT failures for one of the monitored TX resource pools exceeds a threshold, indicating a consistent LBT failure. The WTRU may, based on the consistent LBT failure, send an indication of the consistent LBT failure for the TX resource pool to peer WTRUs. and an indication of the consistent LBT failure for the TX resource pool to a serving cell.

    Abstract: The exchange of resource allocation assistance information between a requester User Equipment (UE) and an assistant UE allows the requester to make better resource allocation decisions. The assistance information may include a blacklist, a whitelist, resource allocation information, a candidate resource set, and measurement information, for example. Both UEs may have an assistance configuration to assist in the exchange of resource allocation assistance information, that may be obtained from a third apparatus, such as a base station. The configuration may include information related to when to trigger assistance, identities of UEs, and types of assistance information, for example. The requester may, based on the assistance information received, modify a candidate resource set at a Medium Access Control (MAC) layer. The requester may, at the MAC layer, determine a configured sidelink grant for a selected destination using assistance information targeting this destination.

    Abstract: Methods, apparatus, systems, architectures and interfaces for compressing hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback bits performed by a wireless transmit/receive unit (WTRU) receiving a transmit block (TB) including code block group (CBG) data are provided. The method includes receiving, by the WTRU, information associated with transmitting compressed HARQ-ACK feedback information, receiving, by the WTRU, a TB; determining, by the WTRU, a countdown downlink assignment index (CD_DAI) associated with the received TB; generating, by the WTRU, the compressed HARQ-ACK feedback information by compressing HARQ-ACK feedback bits associated with the received TB; and on condition that: (1) the CD_DAI is equal to zero or (2) the WTRU determines to provide feedback information, transmitting the compressed HARQ-ACK feedback information.
