Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing channel state information (CSI) reporting that includes a stale CSI report. Based at least in part on a CSI reporting configuration, a user equipment (UE) performs CSI measurements during a current reference time period, and generates one or more CSI reports including at least a stale CSI report. A stale CSI report is generated based at least in part on CSI measurements performed prior to the current reference time period. The UE further generates an uplink message including the one or more CSI reports, and transmits the uplink message to the base station under a reporting setting determined by the CSI reporting configuration.

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: The exemplary embodiments relate to determining which instance of control information is to be used for transmitter beam selection. A user equipment may receive a medium access control (MAC) control element (CE) that includes first control information associated with transmitter beam selection, transmit an acknowledgement (ACK) to the network in response to receiving the MAC CE and receive a downlink signal over a physical downlink control channel (PDCCH) that schedules an uplink transmission. The downlink signal is received prior to an expiration of a predetermined duration relative to transmitting the ACK and includes second control information associated with transmitter beam selection. The UE may also transmit an uplink signal based on the scheduled uplink transmission. The UE selects a transmitter beam for the uplink signal based on one of the first control information or the second control information.

Abstract: A user equipment (UE) is configured for half-duplex operations with a network. The UE determines that half-duplex (HD) frequency division duplex (FDD) is enabled by a network with which the UE is communicating, wherein a guard period is configured for downlink and uplink switching when the HD FDD is enabled, performs a first uplink transmission at a first time and performs a first downlink reception at a second time, wherein the guard period represents a time duration between the first time and the second time during which the UE is not to perform a second different uplink transmission or a second different downlink reception.

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.
