Abstract: A method and apparatus are described for a low cost machine-type-communication (LC-MTC) wireless transmit/receive unit (WTRU) to enhance coverage. An example method for physical broadcast channel (PBCH) enhancement includes receiving system information on an enhanced PBCH (ePBCH). The ePBCH is located in a set of radio frames which is a subset of available radio frames, where the subset includes fewer than all the available radio frames. The ePBCH is received in at least one radio frame of the set of radio frames. An example method for physical random access channel (PRACH) enhancement includes receiving configuration of legacy PRACH resources and enhanced PRACH (ePRACH) resources. The WTRU selects one of legacy PRACH resources or ePRACH resources based on a coverage capability. Another example method for PRACH enhancement includes receiving configuration of ePRACH resources. The ePRACH resources include multiple ePRACH resource types, each ePRACH resource type being associated with a coverage capability.

Abstract: Methods, apparatuses and systems directed to enhanced control channel and shared channel transmissions at high frequencies are provided. Among the methods is a method that may include any of receiving downlink control information indicating a modulation and coding scheme (MCS), a time domain resource assignment, and a frequency domain resource assignment; obtaining a subcarrier spacing (SCS) and a cyclic prefix (CP) length based on the MCS; determining the time and frequency domain resource assignments based on the SCS and the CP length; and receiving a downlink transmission at time and frequency resources associated with the time and frequency domain resource assignments.

Abstract: Methods, apparatus and systems are disclosed. In one embodiment, a method may be implemented by a first Wireless Transmit/Receive Unit (WTRU). The method may include receiving configuration information indicating a first set of RBs for performing a CSI-RS measurement, receiving an indication indicating a second set of RBs, and receiving an indication indicating that a first set of symbols or slots is not configured for a certain type of duplexing method and a second set of symbols or slots is configured for the certain type of duplexing method. The method may also include measuring a first CSI-RS in the first set of RBs in a symbol or slot in the first set of symbols or slots, measuring a second CSI-RS in a symbol or slot of the second set of symbols or slots in RBs that are in both the first set of RBs and the second set of RBs. determining a CSI based on the measurement of the first CSI-RS and the second CSI-RS, and reporting the CSI.

Abstract: Methods and apparatus for recovering from a beam failure in a non¬terrestrial communication network are provided. A method may include receiving (610) configuration information indicating a first set of RSs including one or more first RSs associated with a first BWP of a cell, and second sets of RSs that each include one or more second RSs associated with a second BWP. The method may include determining (620) a candidate set of RSs from the plurality of second sets of RSs based on any of a location and a timing advance value associated with the WTRU, selecting (630) an RS from the candidate set of RSs that have measured signal characteristics that satisfy a threshold, and transmitting (640) a PRACH transmission associated with the selected RS in the one of the one or more second BWPs associated with the selected RS during a period in which current operation with the first BWP is suspended.

Abstract: Methods and apparatuses for Sidelink (SL) communication are disclosed herein. A method for SL communication performed by a Wireless Transmit/Receive Unit (WTRU) may include receiving a plurality of resources over a Physical Sidelink Control Channel (PSCCH) in a slot. In addition, the method may include determining the plurality of resources in the slot are control information resources and determining a control information resource type associated with the control information resources. The method may include determining a priority of the control information resource type based on a configuration relating priorities to control resource information types. The method may also include determining a Quality of Service (QoS) of the transport block (TB) associated with the control information resource type. Moreover, the method may include decoding the PSCCH according to the determined priority of the control information resource type.
