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: Method, apparatus, and systems for flexible aperiodic reference signal (RS) transmissions are provided. For example, a method implemented in a wireless transmit/receive unit (WTRU) for wireless communications comprises receiving configuration information of one or more sounding reference signal (SRS) resource sets, each SRS resource set of the one or more SRS resource sets is associated with a slot offset and a set of slot offset deltas; receiving downlink control information (DCI) indicating an SRS request, the SRS request indicates an SRS resource set of the one or more SRS resource sets; determining an SRS configuration from a set of SRS configurations for SRS transmissions; determining a slot for transmitting an SRS based on the determined SRS configuration; and transmitting, in the determined slot, the SRS using resources of the indicated SRS resource set.

Abstract: A method and apparatus for performing a channel access procedure and transmitting a set of repetitions is disclosed. A wireless transmit/receive unit (WTRU) may be configured to receive information to transmit uplink data. The information may indicate a first number of nominal repetitions and a first number of symbols for each of the first number of nominal repetitions. The WTRU may be configured to determine a set of symbols associated with a first nominal repetition and to transmit a second number of actual repetitions in symbols associated with the first nominal repetition. The second number of actual repetitions and the symbols used to transmit the second number of actual repetitions may be based on an occurrence of an event during the set of symbols associated with the first nominal repetition. The set of symbols associated with the first nominal repetition may comprise one or more subsets of consecutive uplink symbols.
