Abstract: Apparatuses and methods are disclosed for panel selection for uplink (UL) transmission in a multi-transmission-reception point (TRP) system. A method performed by a wireless transmit/receive unit (WTRU) may include receiving, for each of a plurality of transmit/receive points (TRPs), information for measuring a first set of reference signals and spatial relation information, the spatial relation information associating each of one or more transmit beams with one or more of a second set of reference signals and with physical uplink control channel (PUCCH) resources. The method may include, for each of the plurality of TRPs, measuring a pathloss of each common reference signal among the first and second set of reference signals. The method may include selecting a transmit beam and a TRP and sending a transmission to the selected TRP. The transmit beam may be associated with an antenna panel of the WTRU.

Abstract: Method, apparatus and systems are disclosed that may be implemented in a wireless transmit/receive unit (WTRU). In one representative method implemented in a WTRU, the WTRU may determine a first CSI report associated with a first TRP, and determine a second CSI report associated with a second TRP. A priority between the first CSI report and second CSI report may be determined. The priority (e.g., priorities of the first CSI report and second CSI report) may be based at least in part on whether inter-cell mTRP is configured. One of the first CSI report and second CSI report having a higher priority may be transmitted to a network. Other representative methods relate to blind decoding priority determination, selection of PUCCH configurations, timing advance adjustments and beam application time determination.

Abstract: Methods and apparatuses for scheduling and receiving a downlink data transmission are provided. A method comprises receiving a higher layer configuration for one or more Physical Downlink Shared Channel (PDSCH) candidates. Each PDSCH candidate may have one or more Code Blocks (CBs) or Code Block Groups (CBGs). The method comprises monitoring a search space for a Group-Common Physical Downlink Control Channel transmission. The transmission includes a Downlink Monitoring Indication (DMI) flag that activates blind decoding. Blind decoding may be performed for CBs or CBGs in the PDSCH candidates. Limits may be applied to a total number of CBs or CBGs for which to attempt blind decoding. The method may further comprise selecting a subset of PDSCH candidates for which blind decoding of the CBs or CBGs will not exceed the limits. Blind decoding may then be attempted on one or more CBs or CBGs in the selected candidates.

Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beamin the beam group.

Abstract: Systems, methods, and instrumentalities are disclosed for physical (PHY) layer multiplexing of different types of traffic in 5G systems. A device may receive a communication. The communication may include a first traffic type. The device may monitor the communication for an indication that the communication includes a second traffic type that is multiplexed with and/or punctures the first traffic type. An indicator received in the communication and detected by the monitoring may indicate where the second traffic type is located in the communication. The first traffic type and the second traffic type may be multiplexed at a resource element (RE) level. For example, a first traffic type may be punctured by a second traffic type at the RE level. The device may decode one or more of the first or second traffic types in the communication based on the indication.

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: Systems, methods, and instrumentalities are disclosed herein associated with positioning in wireless systems. Features may be implemented, for example, in the behavior of a wireless transmit/receive unit (WTRU) for measurement reporting during a multi-beam channel scan, in WTRU behavior during a measurement report in the presence of a multipath, and/or in WTRU behavior during reporting to acquire correction information from the network. A WTRU may receive a PRS transmission via multiple paths, wherein the paths may be associated with the beams. The WTRU may report Rx-Tx time differences associated with the reception of the PRS transmission via multiple paths and transmission of respective SRSp's associated with the respective paths.
