Abstract: An apparatus in accordance with the present application may monitor a sidelink (SL) connection. The apparatus includes processing circuitry that receives signals in a protocol stack to perform SL-radio link monitoring (SL-RLM), and determines, according to the signals, whether a SL-radio link failure (RLF) has occurred. The signals may include hybrid automatic repeat request (HARQ) feedback. In a case that the signals include a HARQ-NACK, the processing circuitry determines that the SL-RLF has occurred. The processing circuitry further receives configuration information related to the SL-RLM for the signals, the configuration information including configurations for measurement quantities of the signals and a condition for declaring SL-RLF, configures, according to the configuration information, lower layers of the protocol stack for the SL-RLM for the signals, and performs SL-RLM measurements of the measurement quantities.

Abstract: Open loop power control may be based on an estimated pathloss. A set of transmission and reception points (TRPs) may provide a set of reference signals (RSs) to a reference point (RP). The RP, and/or the RP in conjunction with a network with which the RP is associated, may determine a RSRP for each received RS (signature of RSRPs). A WTRU may be configured with the signature of RSRPs. The TRP may provide the set of RSs to the WTRU. The WTRU may determine a set of RSRPs for the received RSs (RSRPWTRU). The WTRU may determine a difference between the signature RSs and RSRPWTRU. The WTRU may determine an estimated uplink pathloss associated with the WTRU and the RP based on the determined difference. The determined pathloss may be utilized in open-loop power control.

Abstract: A WTRU may detect a reflected SSB transmission from a RIS. The reflected SSB is associated with an index. The WTRU may determine a source device of the reflected SSB transmission based on the index. For example, the WTRU may determine that the reflected SSB transmission was reflected by the RIS based on the index associated with the RIS. The WTRU may perform a random access procedure with a network device via the RIS based on the index. The SSB transmission may be associated with an SSB burst transmission comprising a plurality of SSB transmissions, where each of the plurality of SSB transmissions may be associated with the index. The plurality of SSB transmissions may comprise SSB transmissions reflected by the RIS and/or SSB transmissions not reflected by the RIS. The spatial state of the RIS may be maintained constant and/or may change during the SSB burst transmission.

Abstract: Systems and methods for PDCCH reliability are disclosed. The PDCCH may be improved by introducing multi-TRP, multi-beam or repeated, PDCCH transmission and reception. In some methods and systems, PDCCH is transmitted on multiple CORESETs (Control Resource Set), where each CORESET is associated with a TCI state. In some cases, it is beneficial if a UE can determine that multiple received DCIs are duplicates, in order not to duplicate the corresponding UE action. Methods and systems for DCI duplication determination are disclosed. In some methods and systems, PDCCH is transmitted in a single CORESET, where the CORESET is associated with multiple TCI states. Various ways to apply the different TCI states to different disjoint frequency parts of the CORESET or the whole CORESET are proposed. Furthermore, the TCI state used for PDCCH may be used for subsequent PDSCH reception as well, in some cases.

SL transport block is transmitted. If no explicit NACK, is received before the SL timer expires, then ACK. may be assumed. If LBT failure rate is high, then explicit ACK and implicit NACK may be used. A second SL timer may start. If no explicit ACK is received before the SL timer expires, then NACK may be assumed.

Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC_IDLE and RRC_INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling. Downlink repetition for MBS in RRC idle/inactive may include PDSCH repetition and/or PDCCH repetition.

In some embodiments, the “number of SSBs per PRACH resource” parameter value is associated with the number of frequency multiplexed PRACH resources and/or the number of symbols in the PRACH preamble format. Embodiments of the disclosed technology enable more flexible random access configurations and allow a wider range of network implementations.
