Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of abase station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.

Abstract: Systems, methods, and instrumentalities are disclosed for Uplink operation in LTE unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may receive licensed assisted access (LAA) configuration information, e.g., for a first cell from a second cell. The first cell may be associated with operation in an unlicensed band, and the second cell may be associated with operation in a licensed band. The WTRU may determine whether a first subframe is a sounding reference signal (SRS) subframe for the first cell. If the first subframe is an SRS subframe for the first cell, the WTRU may determine SRS resources for the first subframe and determine whether the WTRU is triggered to transmit an SRS transmission in the first subframe. If it is determined the WTRU is triggered to transmit the SRS transmission in the first subframe, the WTRU may transmit the SRS transmission on the SRS resources for the first subframe.

Abstract: Logical Channel Prioritization (LCP) may be enhanced by accounting for Quality of Service (QoS) attributes of single hop and multi-hop paths. QoS attributes may be communicated as a QoS budget comprising a number of attributes, or as a single composite QoS “resistance” factor that quantifies the compounded impact of number of hops, latency, load conditions, and the like. The QoS budget or resistance may dynamically adjusted, and may be used by LCP to provide differentiated uplink resource allocation to data of the bearer or logical channel subject to different transmission paths between the transmitter and the receiver, for example. QoS budget and resistance information may be used to, e.g., enhance Buffer Status Report (BSR) and Scheduling Request (SR) operations.

Abstract: Disclosed herein are new radio (NR) Data link architecture options including, for example, NR radio bearer models, NR logical channel models, and MAC and HARQ models. Further described are packet flows mapping to data radio bearers (DRBs), and a new flow encapsulation protocol in the user plane. In some embodiments, DRBs with different quality of service (QoS) are pre-established, but not activated. This allows a given user equipment (UE) to use these DRBs for packet data network (PDN) flows without a large overhead. Pre-established DRBs can be an extension to default bearer concept with the decision of pre-establishment of DRBs based on UE capability, subscription profile, operation policy, installed apps, etc.
