Abstract: A method performed by a transmitting, Tx, WTRU performing sidelink, SL, communications with a receiving, Rx, WTRU, includes sending a periodic SL resource allocation request to a base station, BS, including directional information comprising a direction of transmission to the Rx WTRU, receiving configuration information of multiple sets of periodic time-frequency, T-F, resources for SL communication with the Rx WTRU, the configuration information including an indication of a first set of the multiple sets of T-F resources to use for SL communication with the Rx WTRU, and transmitting on SL to the Rx WTRU using the first set of T-F resources using the direction of transmission to the Rx WTRU.

Abstract: Method, apparatus and systems are disclosed. In one representative embodiment, a method may be implemented by a wireless transmit/receive unit (WTRU) for communication via a network access point (NAP). The method may include the WTRU receiving from the NAP a set of preambles and corresponding propagation delay related thresholds and determining propagation delay related information associated with a distance between the WTRU and the NAP or a location in a coverage of the NAP. The method may further include selecting a subset of preambles from the set of preambles based on the determined propagation delay related information, randomly selecting a preamble from the selected subset of preambles, and sending the randomly selected preamble to the NAP.
