Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for channel occupancy rate determination of a channel between a user equipment (UE) and a base station in an unlicensed spectrum. A UE can perform measurements based on a measurement configuration from the base station, and further determine a channel occupancy rate of the channel based on the performed measurements. The measurement configuration indicates to the UE to perform an omni measurement or a directional measurement by using an antenna element of the UE. The UE can further transmit a report to the base station to indicate the channel occupancy rate.

Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.

Abstract: A base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

Abstract: A user equipment (UE) is configured to report channel state information (CSI) to a base station of a network. The UE receives configuration information from the base station including one or more interference measurement resources (IMRs) to be measured by the UE, determines a noise power for each of the IMRs, transmits a reference channel state information (CSI) report the base station, measures CSI reference signals (CSI RS) transmitted by the base station to determine an interference and noise power for each of the one or more IMRs and transmits a new CSI report including one of i) only interference and noise power fluctuation feedback or ii) multiple signal-to-interference-plus-noise ratio (SINR) or SINR statistics to the base station.

Abstract: A user equipment (UE) may be scheduled as part of a group of UEs. The UE receives a radio network temporary identifier (RNTI) associated with the group of UEs that includes the UE. The UE receives a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected, the signal scrambled by the RNTI and including control information. The UE decodes the signal using the RNTI and performs an operation in response to the control information.

Abstract: A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.
