Abstract: Methods and apparatuses are described herein for selective one-shot hybrid automatic repeat request (HARQ) feedback by priority level. For example, a wireless transmit/receive unit (WTRU) may determine a priority associated with each transport block (TB). The each TB may correspond to respective HARQ processes associated with downlink transmissions from a base station (BS). The WTRU may receive, from the BS, a request for the one-shot HARQ feedback with an indication of a priority selected for the one-shot HARQ feedback. The WTRU may generate a HARQ codebook for transmission of the one-shot feedback. The HARQ codebook may comprise one or more information bits corresponding to one or more TBs determined based on the indicated priority. The WTRU may determine, based on a number of the one or more information bits, a transmission power and transmit, at the transmission power, the one-shot feedback comprising the generated HARQ codebook.

Abstract: A method, performed by a wireless transmit receive unit for of activating or deactivating at least one in-carrier guard band in a bandwidth part includes receiving a configuration of a set of in carrier guard bands, receiving a channel resource configuration associated with a guard band of the set of in-carrier guard bands, and receiving an indication that the guard band is activated or deactivated. On condition that the guard band of the set of in-carrier guard bands is deactivated, performing a measurement on at least one received reference signal in resources of the channel resource configuration including resources in the deactivated guard band. On condition that the guard band is activated, performing a measurement on at least one received reference signal in resources of the channel resource configuration excluding resources in the activated guard band.

Abstract: Methods and apparatuses are described herein for reporting channel failure, and may be used, among others, for New Radio (NR) operation in unlicensed spectrum (NR-U). Upon detecting a consistent uplink (UL) listen-before-talk (LBT) failure or upon detecting a beam failure on a cell, a Scheduling Request (SR) may be triggered to have a UL resource granted for transmission of the failure to another cell, or to a subset of other cells, using, for example, a failure recovery Medium Access Control-Control Element (MAC-CE). If no grant of an available UL resource can be obtained for transmission of the MAC-CE, or the grant is not suitable for the failure reporting, a failure recovery SR may be transmitted repeatedly to obtain an UL grant suitable for transmitting the failure report. In some cases, a WTRU may initiate a random-access procedure for transmitting the MAC-CE, for example when resources for failure reporting are not configured.

Abstract: Methods, apparatus, systems, architectures and interfaces for performing a configured grant (CG) uplink (UL) transmission are provided. The method includes receiving configuration information associated with a plurality of CG configurations for CG UL transmission; determining to transmit the CG UL transmission according to any of: (1) a set of available channel bandwidths, (2) a number of code block groups (CBGs), and (3) transmission parameters associated with the CG UL transmission; selecting a first CG configuration according to any of: (1) the set of available channel bandwidths, (2) the number of code block groups (CBGs), and (3) the transmission parameters associated with the CG UL transmission; and transmitting any number of CBGs as the CG UL transmission using resources associated with the selected first configuration, wherein the resources of the selected first CG configuration are entirely within the set of available channel bandwidths.
