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 network mitigates paging false alarms. A network component of the network determines a paging area for a user equipment (UE), wherein the paging area comprises a plurality of cells of the network, determines one of a most recent one of the cells of the paging area with which the UE was in a radio resource control (RRC) connected state or a coverage area of one of the cells in which the UE is currently located and configures a page to be transmitted to the UE from a subset of the plurality of cells of the paging area, wherein the subset is based on at least the determination of the most recent one of the cells with which the UE was in a radio resource control (RRC) connected state or the one of the cells in which the UE is currently located.

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.

Abstract: Techniques of beamforming in reference signal (RS) transmissions, applicable to frequency ranges including frequencies between 52.6 GHz and 71 GHz, are described. Such techniques may include determining a communication channel is unoccupied for an initial duration, determining a number of communication slots of the communication channel to defer for transmission, and counting one or more communication slots of the communication channel that are not in use. The techniques may include determining the number of counted one or more communication slots is not equal to the determined number of communication slots of the communication channel to defer, and transmitting one or more data units based on the determination that the number of the counted one or more communication slots is not equal to the determined number of communication slots of the communication channel to defer.

Abstract: A user equipment (UE) is configured to handle physical downlink shared channel (PDSCH) transmissions during multi-transmission/reception point (TRP) operation. The UE receives a physical downlink control channel (PDCCH) transmission configured with downlink control information (DCI) in a single-DCI, multi-transmission/reception point (TRP) operation, wherein the DCI schedules reception of a physical downlink shared channel (PDSCH) transmission, determines whether or not a TCI field is configured in the DCI, when the TCI field is not configured in the DCI, determining a default beam based on a control resource set (CORESET) with the lowest ID in the PDCCH and when the TCI field is configured in the DCI, determining whether the TCI field indicates a TCI codepoint includes two TCI states.

Abstract: A user equipment (UE) reports channel state information for multiple transmission reception points (TRPs) to a network. The UE collects channel state information (CSI) corresponding to multiple transmission reception points (TRPs), receives a signal configured to trigger a semi-persistent CSI (SP-CSI) report from a first TRP of the multiple TRPs, generates a SP-CSI report that includes CSI corresponding to each TRP of the multiple TRPs and transmits the SP-CSI report to a cell associated with the multiple TRPs.

Abstract: This disclosure describes the following enhancement to improve the PDCCH reliability: PDCCH aggregation and multi-beam PDCCH reception for a 5G wireless communication system. The disclosed techniques entail obtaining repeated PDCCH by processing a PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter including an information element (IE) indicating a number of consecutive slots in which the PDCCH is repeated. In another embodiment, a gNB generates the PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter for configuring a UE to receive the repeated PDCCH and employ the multi-beam PDCCH reception.
