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: Systems, methods, and circuitries are disclosed for avoiding slot decoding failure due to beam switching of a common beam. In one example, a baseband processor for a user equipment (UE) is configured to cause the UE to perform various operations. The operations include receiving a data transmission on a plurality of component carriers (CCs) carrying corresponding symbols on a common beam; receiving a beam switch command from the network node, wherein the beam switch command is configured to cause the UE to switch a receiving (RX) beam at an end boundary of a first symbol of the data transmission; identifying one or more symbols for restricted scheduling in one or more CCs of the plurality of CCs based on the beam switching on the first symbol; and ignoring the one or more symbols identified for restricted scheduling for decoding of the data transmission.

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.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations for resource allocation for contiguous resource block transmission. In one aspect, the operations can include actions of identifying a set of sub-channels that are not suitable for serving as leading sub-channels for Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel (PSSCH) transmission, and excluding the identified set of sub-channels from a candidate set of resources.

Abstract: A user equipment (UE) is configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.
