Abstract: The present application describes a WTRU including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor capable of executing instructions of determining, based upon a measurement in an active downlink bandwidth part (DL BWP), to initiate a random access channel (RACH) procedure. The processor also executes instructions of switching to a default uplink bandwidth part (UL BWP). The processor also executes instructions of initiating the RACH procedure. The process further executes instructions of transmitting a RA preamble using one of the RACH resources configured for the default UL BWP. The processor even further executes instructions of receiving a RA response. The processor yet even further executes instructions of switching from the default UL BWP to either an active UL BWP or another active UL BWP after re-establishing the RRC connection.

Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

Abstract: Radio resource management measurements for new radio unlicensed are performed that are based on a measurement model where a missed received signal transmission opportunity indicator is provided to higher layers to adapt the measurement functions performed by the radio resource control when a missed received signal transmission opportunity is detected. Radio link monitoring for new radio unlicensed is performed based on in-sync or out-of-sync indications that are based on the estimated radio link quality in combination with missed radio link monitoring reference signal transmission opportunities.

Abstract: The present application is at least directed to an apparatus on a network including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor, operably coupled to the non-transitory memory, capable of executing an instruction of determining a radio link failure has occurred between a first bandwidth part (BWP) of the apparatus tuned to a base station. The processor also executes the instruction of initiating a random access (RA) procedure. The processor also executes the instruction of determining whether a configured contention-based physical random access channel (PRACH) resource overlaps with the first BWP. The process further executes the instruction of transmitting a RA preamble including the configured contention-based PRACH resource to the base station. The processor even further executes the instruction of receiving a RA response from the base station.
