Abstract: Systems and methods described herein are provided for beamforming and uplink control and data transmission techniques. Such techniques enable a UE to maintain at least one beam process for operation with multiple beams and/or points. A beam process may be indicated for transmission or reception over a downlink or uplink physical channel. Power, timing, and channel state information may be specific to a beam process. A beam process may be established as part of a random access procedure in which resources may be provisioned in random access response messages. Techniques are provided to handle beam process failures, to use beam processes for mobility, and to select beams using open-loop and closed-loop selection procedures.

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 systems are described herein for bandwidth part (BWP) operation in 5G wireless systems. A wireless transmit/receive unit (WTRU) may be configured to receive a physical downlink control channel (PDCCH) transmission on a first BWP associated with a first carrier. The PDCCH transmission may include scheduling information for receiving a physical shared downlink channel (PDSCH) transmission via a second BWP associated with a second carrier. The WTRU may be configured to determine one or more quasi co-located (QCL) parameters for the PDSCH transmission using a lowest transmission configuration indication (TCI) state associated with the second BWP associated with the second carrier based on a scheduling offset of the PDSCH transmission being less than a threshold and on the PDSCH transmission being received via the second BWP. The WTRU may be configured to receive the PDSCH transmission using the determined one or more QCL parameters.

Abstract: Methods and systems are described herein for bandwidth part (BWP) operation in 5G wireless systems. A wireless transmit/receive unit (WTRU), configured with at least one bandwidth part (BWP), may receive a signal including an indication for the WTRU to perform measurements on a target BWP, which may be received as part of downlink control information (DCI) in the current active BWP. The WTRU may determine a measurement gap type based on at least one of a subcarrier spacing (SCS) of a current active BWP and a SCS of the target BWP. The WTRU may determine a measurement gap for the target BWP based on the measurement gap type. The WTRU may measure channel state information (CSI) in the target BWP during the measurement gap. The WTRU may send a report including the measured CSI in the current active BWP.

Abstract: A wireless transmit/receive unit (WTRU) may receive a configuration message from a first base station including correspondence information regarding a plurality of beam reference signals, the correspondence information including information regarding designation of at least one set of physical random access channel (PRACH) resources for each of the plurality of beam reference signals. The WTRU may measure the plurality of beam reference signals transmitted from a second base station and select a beam reference signal from among the plurality of measured beam reference signals. The WTRU may determine a set of PRACH resources for the selected beam reference signal based on the information regarding designation of at least one set of PRACH resources for each of the plurality of measured beam reference signals included in the correspondence information. The WTRU may transmit, to the second base station, a PRACH transmission using at least one PRACH resource of the determined set.

Abstract: A method and apparatus for determining Physical Random Access Channel (PRACH) resources and using beams are disclosed herein. In an example, a wireless transmit/receive unit (WTRU) may measure a plurality of beam reference signals transmitted from a base station. Further, the WTRU may select a beam reference signal from among the plurality of measured beam reference signals. Also, the WTRU may receive a configuration message from the base station that includes correspondence information regarding the plurality of beam reference signals, wherein the correspondence information designates at least one set of PRACH resources for each of the plurality of beam reference signals. In addition, the WTRU may determine a set of PRACH resources designated for the selected beam reference signal based on the received correspondence information. Moreover, the WTRU may transmit a PRACH signal using at least one PRACH resource of the determined set of PRACH resources.

Abstract: A method and apparatus for power control for wireless transmissions are disclosed. A wireless transmit/receive unit (WTRU) may determine a first transmit power for a first physical channel for a first serving cell in a first timing advanced group (TAG) and a second transmit power for a second physical channel for a second serving cell in a second TAG. The first TAG may be associated with a first timing advance value and the second TAG may be associated with a second timing advance value. The WTRU may determine a WTRU configured maximum output power (PCMAX) for an overlapping portion, which may be a portion of a transmission of the first channel in a first slot that overlaps in time with a portion of a transmission of the second channel in a next slot. The WTRU may adjust at least one of the first physical channel and the second physical channel.
