  • Patent number: 11917634
    Abstract: A base transmission signal and an auxiliary transmission signal may be used to (e.g., concurrently) improve a harvesting efficiency of an energy receiver while maintaining a prespecified performance level of an information receiver. An auxiliary transmission signal may be constructed. The construction of the auxiliary transmission signal may be signaled. An auxiliary transmission signal may be adapted. The adaptation of the auxiliary transmission signal may be signaled. An impact of auxiliary transmission signals on an information receiver's performance may be mitigated. One or more narrowband energy harvesting (EH) signals may be used, for example to provide a high peak to average power ratio (PARR) for EH devices (e.g., without significantly impacting overall transmitted signal PARR) characteristics. One or more narrowband auxiliary signals may be used, for example to enhance the PARR characteristics of an information signal sub-band.

  • Publication number: 20240064818
    Abstract: Methods, systems, and devices for in-channel narrow-band (NB) companion air interface (CAI) assisted wideband (WB) random access channel (RACH) access. Periodic NB downlink (DL) synchronization sequences are detected. Range information is estimated by measuring the periodic NB DL synchronization sequences; and determining an NB CAI RACH occasion. The range information is transmitted to a gNode B (gNB), or other base station, in a NB CAI RACH procedure. At least one selected WB sequence based on the range information and at least one scheduled WB RACH occasion based on the NB CAI RACH occasion are received from the gNB. A contention free WB RACH procedure is performed based on the received at least one selected WB sequence and the at least one scheduled WB RACH occasion.

  • Publication number: 20240007168
    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.

  • Publication number: 20230319747
    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.
