摘要： Described herein is a procedure for determining multiplexing behavior when multiple physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH) resources of different priority indexes overlap in time. The wireless transmit/receive unit (WTRU) determines a multiplexing indication applicable to a set of resources overlapping in time, at least one condition associated to the multiplexing indication, and multiplexes a subset of the resources based on whether the at least one condition is satisfied. Further described herein are solutions for selecting a grant on which uplink control information (UCI) is multiplexed in the case that no data is available for transmission and the grants are of multiple priority indexes. Also described herein are solutions for reporting accurate power headroom applicable to simultaneous transmission of PUCCH and PUSCH when the PUCCH and PUSCH may be of different priority indexes.

摘要： A method performed by a WTRU may comprise receiving PRS configuration information and performing a first set of measurements based on the PRS configuration. The method may further comprise determining whether to trigger an on-demand PRS request based on the first set of measurements and on-demand PRS criteria. On a condition that the determining to trigger is affirmative, transmitting an on-demand PRS request. In embodiments, the on-demand PRS criteria may be based on an RSRP, TDoA, number of multipaths, accuracy and/or latency.

摘要： Systems, methods, and instrumentalities are described for handling positioning reference signals in a wireless communication system. The positioning reference signals may be assigned priorities that may be used to facilitate various operations of a wireless transmit/receive unit (WTRU) such as positioning related services, collision avoidance, measurement and reporting, etc. The WTRU may be configured with multiple muting patterns associated with the positioning reference signals and may switch between different muting patterns based on the priorities of the positioning reference signals and/or other downlink (DL) or uplink (UL) transmissions that may overlap or collide with the positioning reference signals.

摘要： Channel access in unlicensed spectrum may be a function of the type of physical channel and/or a procedure that initiated a transmission. An LBT procedure may be performed as a function of beam management. A WTRU may access a channel using multiple channel access methods associated with multiple uplink transmissions based on a determination of persistent interference associated with the channel. Channel access methods may be performed with different parameters or characteristics based on the resource type/timing of the transmission/measurements of DL/UL RS. Channel access methods may be characterized by a sensing duration, an ED threshold, a beam width, and/or a beam direction. Different ED thresholds may be applied as a function of one or more characteristics of an applicable beam. Multiple sensing methods and/or related parameters may be applied as a function of the type of physical channel and/or the type of procedure associated with a transmission.

摘要： Methods, apparatus, systems, architectures and interfaces for performing a configured grant (CG) uplink (UL) transmission are provided. The method includes receiving configuration information associated with a plurality of CG configurations for CG UL transmission; determining to transmit the CG UL transmission according to any of: (1) a set of available channel bandwidths, (2) a number of code block groups (CBGs), and (3) transmission parameters associated with the CG UL transmission; selecting a first CG configuration according to any of: (1) the set of available channel bandwidths, (2) the number of code block groups (CBGs), and (3) the transmission parameters associated with the CG UL transmission; and transmitting any number of CBGs as the CG UL transmission using resources associated with the selected first configuration, wherein the resources of the selected first CG configuration are entirely within the set of available channel bandwidths.

摘要： Methods and apparatuses for synchronization in wireless systems includes a wireless transmit/receive unit (WTRU) where the WTRU selects a side-link synchronization signal and physical side-link broadcast channel (SL-SSB) resource-set, based on the the WTRU's properties. Thereafter, the WTRU may transmit its properties, like geolocation, to a base station (gNB). Following this, the WTRU may receive an identification (ID) to be a part of a group of other WTRUs and to be distinguished from other WTRUs in the group by the ID, where the group is created based on similar properties between each WTRU in the group. After this, the WTRU may receive from a gNB, network layer, or other WTRU, a SL-SSB to transmit, based on the WTRU's ID.

摘要： Methods and apparatus are described herein. A wireless transmit/receive unit (WTRU) includes a receiver, processor, and a transceiver. The receiver is configured to receive, from a base station (BS), configuration information that includes a WTRU-specific fixed frame period (FFP) and one or more configured grant (CG) resources. The processor is configured to determine whether to transmit data using a first CG resource of the one or more CG resources and whether to use either the BS-initiated channel occupancy time (COT) or a WTRU-initiated COT. The processor further performs a listen before talk (LBT) based on the COT the WTRU determined to use; and on a condition that the LBT was successful, a transmitter configured to transmit the data and uplink control information (UCI) in the first CG resource.

摘要： A wireless transmit receive unit (WTRU) may be configured to monitor physical downlink control channel (PDCCH) candidates of a primary cell (PCell) and a secondary cell (SCell). The WTRU may be configured to determine a time duration for PDCCH candidate budgets for a set of symbols based on a subcarrier spacing associated with the PCell and a subcarrier spacing associated with the SCell. The WTRU may be configured to determine a maximum number of PDCCH candidates to allocate to a search space monitoring occasion of the PCell and the SCell. The maximum number of PDCCH candidates may be based on a per-cell ratio. The WTRU may be configured to allocate PDCCH candidates for the search space monitoring occasion of the PCell and the search space monitoring occasion of the SCell based on the determined maximum number of PDCCH candidates. The WTRU may be configured to decode an allocated PDCCH candidate.
