摘要： The disclosure generally pertains to methods and apparatus for on-demand low-power sidelink channel reservation acquisition in wireless communication systems. A WTRU may determine to request on-demand reports related to sidelink resource usage. A WTRU that receives the report may generate a report based on its knowledge of sidelink resource usage. The responding WTRU may determine a priority associated with the report based on the relative amount of information it has regarding the sidelink resource usage. A response window for the response may be determined based on the priority. The responding WTRU then transmits the report in the corresponding response window. If a collision is detected for the report transmission, the response window may be extended and the report may be retransmitted in the extended response window.

摘要： Systems, devices and methods for a backscatter measurement based multiple RACH preamble transmissions are disclosed. A WTRU may receive a JCS-RS configuration comprising a minimum RACH preamble retransmission interval. The JCS-RS configuration may comprise a JCS backscatter power fraction (λ) of the WTRU transmit power (PTx). The WTRU may transmit a RACH preamble in a RACH occasion corresponding to a preferred SS/PBCH Index using an initial WTRU transmit beam, having an associated first RA-RNTI value. The backscatter power (PBS) may be measured using the WTRU receive beam corresponding to the WTRU transmit beam used for the RACH preamble transmission. On a condition that PBS>λPTx, the WTRU may retransmit the RACH preamble after a retransmission interval, on resources associated with a second RA-RNTI value. The WTRU may be configured for monitoring the PDCCH common search space with the first RA-RNTI and the second RA-RNTI, for respective RAR window intervals

摘要： Systems and methods are described herein for enabling service continuity between standalone non-public network (SNPN) and a public land mobile network (PLMN). A wireless transmit/receive unit (WTRU) may enable service continuity, for example, by triggering a temporary leave of the WTRU from a serving SNPN to prepare a pre-established backup user plane (UP) connection in a PLMN. A network may enable service continuity, for example, by triggering a temporary leave of a WTRU from a serving SNPN to prepare a pre-established backup UP connection in a PLMN. A WTRU may switch back to SNPN from PLMN, for example, using an SNPN priority search mode and/or other WTRU behavior(s).

摘要： Methods for receiving and transmitting downlink transmissions with increased reliability are provided. A method includes receiving configuration information defining first and second search space sets. The first search space set includes a first one or more search spaces each including a plurality of physical downlink control (PDCCH) candidates. The second search space set includes a second one or more search spaces each including a plurality of PDCCH candidates. The configuration information indicates that the first and second one or more search spaces are linked. The method further includes receiving downlink control information (DCI) by detecting, based on the received configuration information, a first transmission using PDCCH candidates of the first one or more search spaces, detecting a second transmission using PDCCH candidates of the second one or more search spaces, and decoding at least one of the first transmission or the second transmission.

摘要： A wireless transmit/receive unit (WTRU) may establish a multi-access (MA) protocol data unit (PDU) in accordance with the examples described herein. The WTRU may establish a new packet data network (PDN) connection or identify a suitable existing PDN connection in an evolved packet core (EPC), establish a MA-PDU in a 5G core network (5GC), and associate the existing PDN with the MA-PDU. The WTRU may already have a MA-PDU session established in 5GC with both 3GGP access leg and non-3GPP access leg in 5GC, and the WTRU may replace the 3GGP access leg in 5GC with a suitable PDN connection in EPC. The WTRU may send a request for establishing a single-access PDU session in 5GC via non-3GPP access, and a 5GC network may upgrade a PDU session established for the WTRU to a MA-PDU with 3GGP access leg in EPC.

摘要： A method for initial timing synchronization for a WTRU to communicate with a network includes receiving an in-channel narrowband synchronization sequence from the network to enable initial coarse timing synchronization, determining coarse timing offset and a range between a beam source of a network transmitter and the WTRU, selecting a wideband sequence for fine timing synchronization using the estimated range, transmitting the selected wideband sequence for fine timing synchronization during an uplink timing occasion, receiving from the network a transmission of the selected wideband sequence for fine timing synchronization, and establishing fine timing synchronization between the WTRU and the network using the selected sequence.

摘要： A wireless transmit/receive unit (WTRU) determines PDCCH candidates. For a slot, the WTRU determines a number of valid PDCCH candidates associated with at least one search space based on a number of designated search spaces associated with the WTRU in the slot, a type of the search space, a priority associated with the search space, a number of required CCE channel estimates associated with the search space, a maximum number of PDCCH candidates in a slot, and a number of control resource sets (CORESETs) associated with the slot. The WTRU may then attempt to decode CCEs in the at least one search space to recover a PDCCH associated with the WTRU. The WTRU may drop PDCCH candidates from the search space when the number of PDCCH exceeds a maximum value.

摘要： Methods and apparatuses are described herein for selective one-shot hybrid automatic repeat request (HARQ) feedback by priority level. For example, a wireless transmit/receive unit (WTRU) may determine a priority associated with each transport block (TB). The each TB may correspond to respective HARQ processes associated with downlink transmissions from a base station (BS). The WTRU may receive, from the BS, a request for the one-shot HARQ feedback with an indication of a priority selected for the one-shot HARQ feedback. The WTRU may generate a HARQ codebook for transmission of the one-shot feedback. The HARQ codebook may comprise one or more information bits corresponding to one or more TBs determined based on the indicated priority. The WTRU may determine, based on a number of the one or more information bits, a transmission power and transmit, at the transmission power, the one-shot feedback comprising the generated HARQ codebook.
