Abstract: Disclosed herein are a plurality of embodiments addressing wireless communications, where one or more of the embodiments specifically address phase noise (PN) compensation techniques in which multiple groups of reference symbols are transmitted by computed splitting of the allocated Physical Resource Block(s) (PRBs) in suitable groups of sizes (e.g., equal or lower than the channel's coherence bandwidth), and ensuring the frequency domain circular symmetric transmission from the transmitting entity side adding the cyclic sub-carriers to each group. There may be one or more designs of techniques to choose suitable numbers and sizes of groups to enable suitable level of PN compensation at a receiving entity and provide various methods to ensure circular symmetry within each group. One or more approaches may be able to adapt to the instantaneous channel conditions and PN characteristics of the transceivers on a per-user basis.

Methods and processes for dynamic grant and periodic resource allocations are discussed. A method for sidelink feedback transmission performed at a base station includes at the base station, creating an independent physical uplink control channel (PUCCH) group for sidelink feedback transmissions from a sidelink user equipment (UE) to the base station, transmitting a downlink control information (DCI) to the sidelink UE scheduling a sidelink transmission and configuring the PUCCH group for transmission of sidelink feedback to the base station, and receiving a sidelink feedback from the sidelink UE on resources which are part of the PUCCH group.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are described that may be implemented in a wireless transmit/receive unit (WTRU) for sidelink (SL) communication. In one representative method, the WTRU estimates a primary direction for a SL transmission. The first WTRU derives a paired direction associated with the primary direction. SL control information (SCI) sensing in the primary and paired directions may be performed to detect SL transmissions and/or reservations from other WTRUs. The WTRU may select a SL resource using any sensed SCI in the primary and paired directions. The WTRU may proceed to transmit SL control and data over the selected SL resource, such as in a SL slot. For example, the transmission of SL control information may include SCI transmission in the primary and paired directions in the same symbols of a slot.
