Abstract: A wireless transmit receive unit (WTRU) may receive an indication of transmitted synchronization signal blocks (SSBs) comprised in an SSB burst and an indication of skipped SSBs in the SSB burst. The skipped SSBs are not transmitted by a base station in the SSB burst. The WTRU may determine to send an indication that the WTRU wants to use a skipped SSB for or after an initial access procedure. The WTRU may transmit a random access preamble using random access resources and receive at least one downlink transmission using a beam associated with the skipped SSB.

Abstract: Systems, methods, and devices for collaborative positioning. A wireless transmit/receive unit (WTRU) is configured to perform and report positioning measurements including SL collaborative measurements. The WTRU serving as an anchor WTRU may select a set of member WTRUs for distributing the PRS measurement configurations based on the inter-WTRU distance measured over a SL. The selected subset of member WTRUs each provide measurement report to the anchor WTRU. The anchor WTRU reports to the LMF the measurements received from the member WTRUs and the associated SL distance measurements.

Abstract: A WTRU may receive a configuration of PRS reception timing (Tp) and/or SRSp transmission timing (Ts), for example from a first network entity such as an LMF. The WTRU may receive PRS and/or SRS configurations, for example from the first network entity. The WTRU may receive a request (e.g., from the first network entity) to perform a PRS measurement at the configured timing (e.g., Tp slots from when the WTRU receives the request) and an SRSp transmission at the configured timing (e.g., Ts slots from when the WTRU receives the request). The WTRU may send a request (e.g., to a second network entity such as a gNB) for a TxRx window which encompasses the measurement timing of the PRS and the transmission timing for the SRSp, where the start time and/or length of the TxRx window may be determined based on Tp and/or Ts.

The WTRU may determine an overlap between the COT and S-SSB slots, and determine additional required sidelink transmissions after the S-SSB slots. The WTRU may determine the one or more RB sets to be used for sidelink transmission after S-SSB slots. The WTRU may transmit a request for the synchronization reference WTRU to transmit S-SSB on the determined one or more RB sets.

Abstract: Devices, methods, and systems for coverage extension. A bundle of repeated transmissions of a preamble are transmitted responsive to a reference signal received power (RSRP) being less than a threshold and a random access (RA) procedure being initiated. A random access response (RAR) window is monitored for a random access radio network temporary identity (RA-RNTI) corresponding to the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble is transmitted based on a spatial filter that is different from others of the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble comprises a preamble index that is different from preamble indices of others of the repeated transmissions of the preamble. In some implementations, the spatial filter comprises a transmission (Tx) beam. In some implementations, the bundle of repeated transmissions of the preamble comprises retransmissions of a msg1.

Abstract: Beam management may be coordinated by a centralized coordinating entity, e.g., by a gNB, that configures and schedules Channel State Information Reference Signal, CSI-RS, transmissions for beam measurement and reporting. This centralized coordinating entity may not be available for Wireless Transmit-Receive Units, WTRUs, in a SideLink, SL, mode of operation, where resource allocation is performed by WTRUs in a distributed manner. WTRU procedures for establishing and updating an SL TCI state association are disclosed, including determining a spatial domain filter to use for an SL transmission. In these WTRU procedures, a WTRU may perform CSI-RS transmissions in an SL slot, e.g., multiplexed with a PSCCH/PSSCH transmission. The WTRU may receive, in reply, CSI reporting information comprising a spatial domain filter. For further SL TB transmissions for the SL, the WTRU may use the spatial domain filter.
