Abstract: Described are approaches to multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In one approach, only one component carrier is configured with the multi-cell scheduling DCIs, with no DCI configured on the other component carriers. In a second approach, all of the component carriers can be configured with the multi-cell scheduling DCIs. In a third option, one component carrier is configured with multi-cell scheduling DCI only, while the other component carriers can be configured with the legacy single-cell scheduling DCIs. In a fourth option, one component carrier is configured with both multi-cell scheduling DCIs and the legacy single-cell scheduling DCIs, while the other component carriers can be configured with the legacy single-cell scheduling DCIs. In the fifth option, all the component carriers can be configured with both multi-cell scheduling DCIs and the legacy single-cell scheduling DCIs. In addition, dropping rules are described for the situations of overbooking, i.e., when the number of PDCCH candidates exceeds the capabilities of the user equipment (UE). Potential dropping rules include following the legacy procedure, and providing higher priority to candidates with user-specific search spaces with multi-cell scheduling DCIs. Also described is the impact on DCI formats to accommodate single-cell and multi-cell scheduling DCIs on the same component carrier. Finally, limits on the number and sizes of the DCIs are described.

Abstract: Mechanisms are provided for a user equipment (UE) to receive physical downlink shared channel (PDSCH) transmissions of a transport block (TB) over multiple slots. The UE can receive a configuration for a PDSCH transmission of a TB over multiple slots (TBoMS), such as a first number of slots, through a downlink from a base station. The configuration can include an indication of the first number of slots. The UE can further determine a transport block size (TBS) for the PDSCH transmission, and allocate a second number of slots used by the UE to support the PDSCH transmission. Based on the TBS for the PDSCH transmission satisfying a condition, the processor can be configured to receive the PDSCH transmission of the TB over the second number of slots, and decode the PDSCH transmission received.

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: 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.
