    Abstract: A user equipment (UE) apparatus for wireless communication with a base station is provided. The UE includes a transceiver and a processor. The processor is configured to transmit, to the base station, via the transceiver, at least one uplink (UL) data packet in a radio resource control (RRC) inactive state based on a preconfigured UL resource (PUR) configuration, wherein the PUR configuration is defined according to a set of PUR parameters, wherein the set of PUR parameters include at least one of a control resource set (CORESET) configuration including an aggregation level and repetition types; a physical UL shared channel (PUSCH) repetition configuration including a frequency hopping pattern; or a UL narrow beam direction for frequency range 2 (FR2) or a transmission reception point (TRP) association, and wherein the set of PUR parameters is associated with new radio (NR).

    Abstract: A system and a method are disclosed for accessing a wireless medium for a NR-U deployed at 60 GHz. A directional CCA sensing is performed on a set of multiple beams in the medium in which each beam is oriented in a different direction. It is determined whether at least one beam of is busy and, if so, a back-off timer is initialized. The back-off timer is decreased by a predetermined amount based on a determination that all beams of the set of multiple beams are idle. The back-off timer is repeatedly decreased the predetermined amount based on a determination that all beams of the set of multiple beams are idle until the back-off timer equals a predetermined amount. Data is transmitted at least one beam of the set of multiple beams based on the back-off timer equaling the predetermined amount.

    Abstract: A system and a method are disclosed for beam refinement to enable inactive mode transmission in frequency range 2 for 3GPP RedCap devices. A RedCap device receives system information in a SIB1 from a wireless network in which the SIB1 includes information relating to an indication of resources used to transmit a SIB-x. The device receives the SIB-x, which includes an indication of at least one resource, at least one configuration for a Downlink-Reference Signal (DL-RS) transmission, and information relating to a measurement report relating to the beam-refinement measurement that is to be performed by a device. The device receives the DL-RS transmission from the wireless communication network, performs the beam-refinement measurement, and sends a measurement report to the wireless network. Subsequent to sending the measurement report, the device sends an enhanced transmission to the wireless network based on the measurement report.

    Abstract: A method for random access in a communication network may include detecting a first candidate beam at a UE, detecting a second candidate beam at the UE, transmitting, from the UE, one or more first messages of a random access procedure, and indicating, by the one or more first messages, the first candidate beam and the second candidate beam. Another method for random access in a communication network may include detecting a first candidate beam at a UE, detecting a second candidate beam at the UE, receiving, at the UE, traffic information for the first candidate beam and the second candidate beam, selecting the first candidate beam based on the traffic information, and transmitting, based on the selecting, a first message of a random access procedure using the first candidate beam. The traffic information comprises load information.
