Abstract: Embodiments include systems, apparatuses, and methods to enable coupling between a power states and a beam management states. A method is provided for jointly performing beam management and power management in a wireless transmit/receive in unit (WTRU), where the WTRU is configured to operate according to a plurality of power states and a plurality of beam management states that are linked to the plurality of power states such that each power state corresponds to a different beam management state. The method includes detecting a trigger condition; transitioning the WTRU between a first power state to a second power state based on the detected trigger condition; and transitioning the WTRU between a first beam management state to a second beam management state responsive to the transition to the second power state to which the second beam management state is linked.

Abstract: A method and system for flexible resource control for a wireless transmit/receive unit (WTRU) is disclosed. The WTRU may monitor a first control channel region and receive a first control channel transmission in the first control region indicating boundaries of a plurality of numerology blocks of a carrier. The WTRU may then receive a second control channel transmission in a second control channel of a second control region, wherein the second control channel transmission indicates one or more numerology parameters for at least one of the plurality of numerology blocks. The WTRU may then transmit or receive data based on the one or more numerology parameters of the one or more numerology blocks.

Abstract: Systems, methods, and instrumentalities (e.g. aspects of entities, interfaces and procedures in a wireless transmit/receive unit (WTRU) and/or network layers LI, L2, 13) are disclosed for low latency medium access control (MAC) protocol data unit (PDU) assembly in wireless systems, such as 5G flexible radio access technology (RAT) (5gFLEX). Latency may be reduced, for example, by WTRU determination of network transmission parameters and signaling prior to a transmission grant. A WTRU may receive a modulation and coding scheme (MCS), resource range, etc. prior to a grant, e.g., for use in future grants. Data blocks may be incrementally created/encoded prior to a grant. Data units may be segmented, assembled and multiplexed, for example, based on data block sizes that allow MAC and radio link control (RLC) processing prior to a grant. Flexible grant sizes may be provided for early generation of transport blocks before a grant. A minimum guaranteed transport block size (TBS) may be signaled to permit early generation of a MAC PDU. Transmission parameters may be selected prior to a grant, for example, using blind decoding or a DCI reception procedure.

Abstract: Methods for dynamic allocation of reference signals (RS) may be provided. For example, rather than or in addition to using a pre-defined resource element (RE) mapping for determining reference signal locations within a time-frequency grid, a WTRU may receive one or more dynamic indications (e.g., downlink control information received via a physical downlink control channel) that indicate the position of reference signals and/or associate a first reference signal with a second reference signal. For example, the indicated association may indicate that the first and second reference signals were sent by the base station using the same precoder. The association may indicate that first and second reference signals may be used together for channel estimation.

Abstract: Techniques and devices are disclosed for efficient offloading and/or aggregation of resources by providing different levels of connection management in a network. A wireless transmit/receive unit (WTRU) may support additional ECM and/or RRC states (e.g. inactive states) and/or transitions that may enable a WTRU to act without an RRC connection and/or with reduced latency. A WTRU may operate with network resources with and/or without radio resources. A WTRU may operate in parallel with a plurality of layers, including a primary layer for which the WTRU may behave according to LTE or other behavior. The WTRU may be configured for operation in a secondary layer. The WTRU may establish a secondary layer security context and/or a tunnel or routing for the secondary layer for transport of user plane data between the WTRU and a gateway. The WTRU may determine to which layer uplink data may be applicable.

Abstract: Methods and systems are described for determining a total available transmission power at a time interval for a wireless/transmit unit (WTRU) and determining a power level associated with a transmission based on the total available transmission power and a spectrum operation mode (SOM). A SOM may be associated with one or more transmission characteristics. Transmission power may be allocated to the transmission according to the power level determination.

Abstract: Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.

Abstract: Methods and apparatus are described herein for improved efficiency of a wireless transmit/receive unit (WTRU) transmitting transport blocks (TBs). A WTRU may receive configuration information including uplink resources associated with one or more repetition bundles and a target number of retransmissions for a transport block (TB) associated with at least one hybrid automatic repeat request (HARQ) process. Then, the WTRU may transmit a first TB using a first uplink resource in a first repetition bundle based on the configuration information. Further, the WTRU may increment a retransmission counter. On a condition that the retransmission counter is less than the target number of retransmissions, the WTRU may determine a second uplink resource. Further, the WTRU may retransmit the first TB in the determined second uplink resource. Also, the WTRU may further increment the retransmission counter. Moreover, the first, second and third uplink resources may be physical uplink shared channel (PUSCH) resources.

Abstract: A wireless transmit receive unit (WTRU) may be configured to receive configuration information from a network regarding a set of spatial filters for the WTRU to use to communicate with the network. Each of the spatial filters may be associated a beam group and/or a measurement resource. The WTRU may further receive downlink control information (DCI) that indicates one or more time periods in which a portion of the set of configured spatial filters may be applicable. Based on the configuration information, the DCI, and/or a measurement, the WTRU may select a spatial filter from the portion of spatial filters to apply in the time period, and the WTRU may perform a communication task in the time period using the selected spatial filter.

Abstract: Methods and apparatuses are described herein for accessing an unlicensed spectrum using portions of a carrier's bandwidth (BW). For example, a wireless transmit receive unit (WTRU) may access a serving cell through an initial bandwidth part (BWP). The WTRU may be configured with a plurality of BWPs within an unlicensed frequency spectrum. The WTRU may then determine any of at least one monitoring period and at least one offset per each BWP. The WTRU may then monitor the BWPs based on any of the at least one monitoring period and the at least one offset. The WTRU may receive at least one signal from the serving cell. The signal may be at least one of a downlink control information (DCI), a synchronization signal block (SSB), a reference signal, or a preamble.
