Abstract: Systems, methods and instrumentalities may be provided for handling a user plane in a wireless communication system. The wireless communication system may be characterized by a flexible air interface. One aspect of the flexible air interface is that transmissions by a wireless transmit/receive unit (WTRU) in the system may have different quality of service (QOS) requirements, such as different latency requirements. The WTRU may adjust its behaviors based on the QoS requirements, e.g., by utilizing preconfigured resources, resource requests, self-scheduling, and/or the like, such that the transmissions may be performed in accordance with their respective QoS requirements.

Abstract: A WTRU may be configured to perform logical channel prioritization. A WTRU may receive an indication (e.g., a mapping) that indicates an association between a first HARQ process ID and a first HARQ processing type and between a second HARQ process ID and a second HARQ processing type. The WTRU may receive an indication (e.g., a mapping) that indicates an association between a first logical channel and the first HARQ processing type and between a second logical channel and the second HARQ processing type. The WTRU may receive an a HARQ process ID indication. The WTRU may determine a HARQ processing type associated with the HARQ process ID. The WTRU may determine a logical channel available for a transmission. The logical channel available to be used may be determined based on the HARQ processing type associated with the HARQ process ID. The WTRU may send the transmission.

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: Systems, methods, and instrumentalities may be disclosed for implementing a flexible radio access communication system. A flexible radio access communication system may be supported using spectrum of varying size, including aggregation of non-adjacent carriers in the same and/or in different frequency bands. A wireless transmit/receive unit (WTRU) may receive a first transmission via a common downlink control channel. The first transmission may include first control information. The first control information may include information regarding the configuration of a first dedicated downlink control channel of one or more dedicated control channels. The WTRU may receive a second transmission via the first dedicated downlink control channel of the dedicated control channels. The second transmission may include second control information. The second control information may be associated with a transmission of a first transmission type. The dedicated downlink control channels may be used for providing control information associated with different types of transmissions.

Abstract: A wireless transmit/receive unit (WTRU) may be configured for sidelink (SL) communication. The WTRU may receive SL discontinuous reception (DRX) configuration information from a peer SL WTRU. The SL DRX configuration information may comprise timer information. The timer information may comprise at least a SL on-duration timer, a SL inactivity timer, a SL hybrid automatic repeat request (HARQ) round trip time (RTT) timer, and a SL HARQ retransmission timer. The WTRU may apply the received SL DRX configuration information. The WTRU may report, on a condition that the WTRU has a connection to a network entity, to the network entity that the WTRU applied the received SL DRX configuration information.

Abstract: Logical channel (LCH) may be multiplexed together based on one or more latency requirements. Mapping of LCH(s) to spectrum operating mode(s) (SOM(s)) may be based on SOM capability and/or LCH requirements. A WTRU may determine mapping based on one or more pre-defined rules. The mapping may be based on one or more requirements for the various type of traffic and/or SOM capabilities. A radio bearer may be mapped to one or more SOMs. The WTRU may be configured with a set of SOMs, for one or more, or each, radio bearer. The WTRU may dynamically determine, for example based on radio conditions, buffer status and/or other parameters, the SOM to use. Incompatible multiplexing of LCH may be reduced and/or avoided, perhaps based on using one or more transport blocks (TBs) mapped to the same physical layer (PHY). Traffic may be prioritized based on one or more latency requirements.

Abstract: Systems, methods, and instrumentalities are described herein that may be used to determine a destination for sidelink transmission based on the priority of the transmission and/or other parameters associated with the transmission. In examples, a destination may be selected if one or more logical channels associated with the destination have a bucket size parameter exceeding a certain threshold and the one or more logical channels have a highest priority. Various other techniques are also described herein that relate to the configuration and/or report of QoS information, selection of sidelink resources, use of a minimum communication range, etc.

Abstract: Methods and apparatus for power saving in a wireless network are disclosed. A Wireless Transmit/Receive Unit (WTRU) may comprise a transmitter, a receiver, and a processor. The processor may determine a processing state pertaining to behavior of the WTRU and determine a minimum amount of resources to be processed for one or more sets of physical resources based on the determined processing state. Each respective set of physical resources may comprise resources in time, and any of frequency or space. For each respective set of physical resources, the time may comprise a frame structure associated with a numerology applicable to the respective set of physical resources, the frequency may comprise any of a frequency location, a bandwidth, or the numerology, and the space may comprise one or more beams. The processor may process the determined minimum amount of resources of the one of more sets of physical resources.
