Abstract: Methods, systems, and apparatus designed to support flexible carrier bandwidths in new radio. Multiple carrier bands may be combined into a single composite carrier depending on channel availability in the carrier bands. A composite carrier indicator (CCI) indicates to network devices, the available carrier bands within the channel occupancy time. In addition, bandwidth part inactivity time is suspended when channel access is not available.

Abstract: A radio device may receive network assistance information relating to uplink channel access procedures, such as channel access types and related listen-before-talk techniques, via layer one signaling or higher layer signaling. For example, information may be provided via DCI, MAC CE, or RRC messaging, e.g,, received in a CORESET preceding the configured PRACH resources. Access procedures may be random access procedures, and may include indication via R.AR messaging. Access procedures may be triggered by a radio access point message, such as a PDCCH order or a handover request.

Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

Abstract: Methods and apparatuses are described herein for prioritizing sidelink communication transmissions. In accordance with one example embodiment, an apparatus may transmit, to a network node, assistance parameters associated with sidelink communication comprising quality of service (QoS) parameters. The apparatus may receive, from the network node, configuration parameters associated with sidelink communication that comprise a logical channel configuration, a mapping of a QoS parameter to a sidelink radio bearer, and a mapping of the sidelink radio bearer to a sidelink logical channel. The apparatus may receive a sidelink resource grant and may select, based on the logical channel configuration, one or more sidelink logical channels to be served by the sidelink resource grant. The apparatus may transmit a generated a medium access control (MAC) protocol data unit (PDU), comprising data associated with the selected one or more sidelink logical channels, using the received sidelink resource grant.
