Abstract: A next generation evolved Node B (gNB) configured to provide an unlicensed bandwidth for communications with a user equipment (UE) performs a listen-before-talk procedure to determine an occupation state of busy or idle for the unlicensed bandwidth. When the occupation state is determined by the gNB to be idle, the gNB signals the UE, via a downlink control indicator (DCI), to conduct a channel access measurement (CAM) on the unlicensed bandwidth, the measurement comprising at least one of an energy detection measurement or a signal quality measurement. A measurement report is received from the UE comprising an indication of the occupation state of the unlicensed bandwidth as determined by the UE.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing transmission of nominal repetitions of data over an unlicensed spectrum. One or more nominal repetitions of data are to be transmitted by a user equipment (UE) over an unlicensed spectrum used for both uplink and downlink transmissions. The one or more nominal repetitions of the data are segmented into multiple actual repetitions of portions of the data. The UE identifies an orphan symbol in an actual repetition of the multiple actual repetitions of portions of the data, and determines a filler symbol to replace the orphan symbol in the actual repetition. In addition, the UE transmits the multiple actual repetitions including the filler symbol in replacement of the orphan symbol to a base station over the unlicensed spectrum.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE reports, to a base station, a reduced PDCCH monitoring capability for at least one group of search space sets (SSS) of a PDCCH, receives, from the base station, a reduced monitoring capability (MO) configuration, wherein the base station determines the reduced MO configuration based on the reported reduced PDCCH monitoring capability and monitors the PDCCH based on the reduced MO configuration.

Abstract: Measurement resources are often limited in 5G and 4G-LTE communications. As a result, SMTC and CSI-RS measurement windows will occasionally be assigned to the same resource elements of a signal frame. This results in a collision that must be resolved, since both measurements cannot be performed simultaneously. The collision can be resolved using restriction, where overlapping resource elements are assigned to either the SMTC or the CSI-RS measurements, or can be resolved using measurement sharing, where overlapping resource elements are divided among the two measurements according to a measurement sharing factor. Various factors, including priority or window periodicity may be taken into account by the measurement rules that dictate collision resolution.

Abstract: Providing coverage enhancements for a user equipment (UE) includes decoding a random access channel (RACH) preamble received from a user equipment (UE) via a physical random access channel (PRACH). A number of repetitions associated with transmitting a random access response (RAR) over a physical downlink shared channel (PDSCH) may be determined in response to the RACH preamble. A transmission for the UE to be sent over a physical downlink control channel (PDCCH) may be encoded. The transmission may indicate the number of repetitions to the UE using one or more reserved bits of a downlink control information (DCI).

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) during a random access channel (PRACH) procedure. The UE receives a physical random access channel (PRACH) resource on a first sub-band of a component carrier (CC), wherein the CC is divided into a plurality of sub-bands and receives a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on a second sub-band of the CC, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.
