Abstract: A base station is configured to receive channel state information (CSI) from a user equipment (UE). The base station transmits configuration information including one or more interference measurement resources (IMRs) allocated for measurement by the UE, receives a reference CSI report from the UE, receives a new CSI report including interference and noise power fluctuation feedback from the UE and selects a modulation and coding scheme (MCS) for the UE based on at least the interference and noise power fluctuation feedback and the reference CSI report.

Abstract: This disclosure relates to techniques for improving capability signaling and performing search space set switching, particularly with large sub-carrier spacings, as in high frequency ranges. In various scenarios, a user equipment (UE) device may signal its capability to perform multi-slot PDCCH monitoring and/or single-slot PDCCH monitoring, e.g., at various sub-carrier spacings, for various PDCCH/DCI types, etc. Various technical difficulties in this area are addressed, including increasing flexibility and versatility in capability signaling, overbooking, signaling and timing of search space set switching, and beam sweeping transmission of DCI Format 2_0, among others.

Abstract: The present disclosure proposes configuration for TB processing over multi-slot, particularly Transmission Block over multi-slot (TBoMS) transmission. Specifically, such configuration for TBoMS may relate to at least one of size determination for TBoMS, scheduling for TBoMS transmission, resources determination and allocation for TBoMS transmission, and so on, and corresponding information related to such configuration can be acquired, set or determined appropriately, so that the TB processing over multi-slot can be performed accordingly.

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: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: Techniques discussed herein can facilitate listen before talk procedures for clear channel assessment signaling. One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive system information including a region indication for clear channel assessment (CCA) procedures. The CCA procedures are associated with a listen before talk (LBT) region configuration for one of a first region, a second region, or a third region. One or more processors are configured to receive a downlink control information (DCI) in a physical downlink control channel (PDCCH) message that includes a DCI CCA indication. Subsequently, the one or more processors are configured to perform an initial LBT procedure associated with the region indication and generate a random access channel (RACH) message after performing the initial LBT procedure. Finally, the one or more processors generate an uplink (UL) message according to the DCI CCA indication.
