Abstract: Methods, apparatuses, systems, etc., directed to random channel access over zero energy (ZE) air-interface(s) are disclosed herein. In an embodiment, a wireless transmit/receive unit (WTRU) may receive a first reference signal. For example, the WTRU may determine that a first signal strength of the received first reference signal may fail to satisfy a strength condition, and responsively the WTRU may: (i) receive a transmission, (ii) determine a sequence and an occasion based on the received transmission, (iii) transmit using the determined sequence on the determined occasion, and (iv) receive a second reference signal from an interrogating WTRU.

Abstract: An Evanescent Cell (EC) refers to a WTRU-centric cell exploiting highly directional transmissions. An EC may comprise one or more beams from one or more BSs/gNBs/TRPs that may be operated by the same or different operators. An EC may be created utilizing knowledge of radio planning having detected the presence of one or more WTRU. A Beam-Group (BG) refers to a group of beams associated with an EC. All beams associated with an EC may be categorized into multiple BGs. Each BG may be made up of one or more beams from multiple BSs/gNBs/TRPs. Multiple BGs within an EC may be enabled to ease the burden of cell management. In one or more embodiments, there may be systems, procedures, and/or devices for EC/BG detection, deactivation, activation, selection, reselection, and augmentation. Further, there may be one or more embodiments for hierarchical system information acquisition as they relate to ECs/BGs.

Abstract: Apparatus for paging for highly directional systems. A WTRU receives a default and/or a dynamic set of active SSBs which indicates the beams/SSBs is used to receive paging DCI, e.g. DCI scrambled with P-RNTI, over PDSCH. A WTRU utilizes the default and/or dynamic set of active SSBs in order to determine PDCCH monitoring occasions, PMOs, that are monitored in the WTRU's paging occasions, POs. A WTRU sends paging activating requests to activate a suitable SSB using associated UL signal/resources, if the suitable SSB fulfills a SSB criteria, if the activation duration has elapsed and if the monitoring duration has elapsed. A WTRU may send one or more paging activation requests to activate multiple SSBs, e.g., a field of view, FOV, around a suitable SSB. Said paging activation requests implements a minimal feedback-based paging procedure for paging in highly directional systems, to which the gNB replies with paging configuration for the suitable SSB.
