Abstract: Methods, apparatus, systems, architectures and interfaces for receiving system information performed by a wireless transmit receive unit (WTRU) having reduced capacity, are provided. A method may include any of: receiving a physical broadcast channel (PBCH) transmission of a cell, the PBCH transmission including information, wherein the information indicates a first control resource set (CORESET) associated with reception of a system information block (SIB); receiving, via the first CORESET, a first physical downlink control channel (PDCCH) transmission including information indicating a first type SIB associated with the first PDCCH transmission, wherein the information indicating the first type SIB includes information indicating a second CORESET that (1) is associated with reception of a second type SIB, and (2) has fewer resource blocks than the first CORESET; and receiving, via the second CORESET, a second PDCCH transmission including information indicating the second type SIB associated with the second PDCCH transmission.

Abstract: Systems, methods, and devices for addressing power savings signals in wireless communication. A wireless transmit receive unit (WTRU) may monitor for an energy saving signal (ESS) while the WTRU is asleep (e.g., prior to a discontinuous reception (DRX) ON duration that includes one or more search spaces). The WTRU may measure the energy of the ESS. If the ESS is below a threshold, the WTRU fallback to a default operation or continue in a current operating mode (e.g., remain asleep to save power). If the ESS is above a threshold, the ESS may be received using a coverage enhancement (CE) level based on a parameter associated with a search space. The parameter may be the highest aggregation level of the one or more search spaces.

Abstract: A wireless transmit/receive unit (WTRU) may comprise a processor and memory. The processor and memory may be configured to receive configuration information indicating measurement relaxation criteria for radio link monitoring (RLM) or beam failure detection (BFD) and a prohibit time period for reporting a measurement relaxation state. The WTRU may determine that the measurement relaxation state of the WTRU has changed based on the measurement relaxation criteria. The WTRU may determine that the prohibit time period has ended. The WTRU may send a report based on the determination that the measurement relaxation state has changed and the determination that the prohibit time period has ended. The report may include an indication of a measurement relaxation state.

Abstract: A wireless transmit/receive unit (WTRU) may determine a first set of beams and a second set of beams, that a respective quality of each beam in the first set of beams is less than a predetermined quality value, and that a beam that is in the second set of beams and not in the first set of beams has a quality that is equal to or greater than the predetermined quality value. The WTRU may select the beam that is in the second set of beams and not in the first set of beams and whose quality is equal to or greater than the predetermined quality value, for a BFR and send a message that indicates the selected beam for the BFR to abase station (e.g., a gNodeB). The WTRU may receive a message comprising the selected beam from the gNodeB.

Abstract: Methods for receiving downlink control information (DCI) are provided herein. A method performed by a wireless transmit/receive unit (WTRU) may include receiving configuration information indicating a location of a monitoring indicator and identifying a first one or more search spaces and a second one or more search spaces. The method may include receiving a first physical downlink control channel (PDCCH) transmission including first DCI, the DCI including the monitoring indicator at the indicated location. The method may include monitoring, based on the monitoring indicator, either the first one or more search spaces or the second one or more search spaces and decoding a second PDCCH transmission detected in either the first one or more search spaces or the second one or more search spaces to receive second DCI.

Abstract: A wireless transmit/receive unit (WTRU) may modulate, based on a number of uplink control bits, a first sequence or the first sequence and a second sequence. The WTRU may spread the first sequence and the second sequence with a complementary sequence pair, concatenate parts of the first sequence and the second sequence in interlaced resource blocks (RBs), and perform an inverse discrete Fourier transform (IDFT) on the interlaced parts. The WTRU may transmit on a physical uplink control channel (PUCCH) a signal outputted by the IDFT.

Abstract: A method for a Wireless Transmit/Receive Unit (WTRU). The method including receiving from a network configuration information indicating multiple frequency layers for positioning reference signals; and at least one activated frequency layer from among the multiple frequency layers. The frequency layers may be associated with one or more carriers for data transmission, wherein the carrier is co-located with its associated frequency layer for positioning; and bandwidth parts (BWPs) within carriers for data transmission. The WTRU may receive from the network activation/deactivation information indicating activation/deactivation of any of a secondary cell (SCell) and a BWP. The WTRU may transmit information indicating, for example, a set of frequency layers used for positioning, wherein the set of frequency layers is enabled according to any of an accuracy requirement, a latency, a measured RSRP of one frequency layer, and a measured CSI-RS corresponding to BWPs being a threshold.

Abstract: A WTRU may be configured to receive, in a first search space (SS) group (SSG), a first downlink transmission. The first downlink transmission may comprise first configuration information associated with power saving and downlink transmission monitoring. The WTRU may be configured to monitor for a second downlink transmission based on the first configuration information. On a condition that the first configuration information indicates a first value, the WTRU may be configured to monitor in the first SSG. On a condition that the first configuration information indicates a second value, the WTRU may be configured to monitor in a second SSG. On a condition that the first configuration information indicates a third value, the WTRU may be configured to skip downlink transmission monitoring in the first SSG for a first interval and monitor in the first SSG. The WTRU may receive the second downlink transmission based on the first configuration information.

Abstract: A wireless transmit/receive unit (WTRU) receives first timing advances and first power control commands from a first eNodeB and second timing advances and second power control commands from a second eNodeB and transmits, to the first eNodeB, a first physical uplink control channel using a first uplink component carrier. The first physical uplink control channel has a first timing adjusted by the first timing advances but not by the second timing advances and a first power level adjusted by the first power control commands but not by the second power control commands. The WTRU transmits a second physical uplink control channel using a second uplink component carrier. The second physical uplink control channel has a second timing adjusted by the second timing advances but not by the first timing advances and a second power level adjusted by the second power control commands but not by the first power control commands.
