Abstract: A method for performing an initial access process includes receiving, by a reduced capabilities (RedCap) user equipment (UE), a synchronization signal (SS)/physical broadcast channel (PBCH) block from a network. The SS/PBCH block may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a first set of physical broadcast channels (PBCH), a second set of PBCH, and a third set of PBCH, wherein the third set of PBCH may be a duplicate of the second set of PBCH. The method may further include decoding, by the RedCap UE, the PSS, the SSS, the first set of PBCH, and the third set of PBCH.

Abstract: A system and method for providing early indication by a reduced capability New Radio (NR) User Equipment (UE). In some embodiments the reduced capability UE informs the network, by its use of a combination of preamble, Random Access Channel Occasion (RO), and initial bandwidth part (BWP), that it is a reduced capability UE. In some embodiments, the reduced capability UE transmits payload data in a Message A message. In some embodiments, the reduced capability UE receives, from the network, a set of candidate uplink resources, and transmits a Message 3 message within a subset of the set of candidate uplink resources.

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 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.
