Abstract: A base station and a user equipment (UE) may exchange messages to perform a Random Access Channel (RACH) procedure. The UE performs measurements on a plurality of signal synchronization blocks (SSBs), selects M physical random access channel (PRACH) groups based on one or more of the measured SSBs satisfying a predetermined threshold, provides the measurements for the M PRACH groups to a base station in an initial access transmission for a RACH procedure and monitors for a random access response (RAR) message based on a repetition number for the RAR message indicated by the base station.

Abstract: A user equipment (UE) receives scheduling information from a base station of a wireless network. The UE monitors a first physical resource to receive a common downlink control information (DCI) portion of scheduling information for the UE, decodes the common DCI portion to determine information for a UE-specific DCI portion that is transmitted by the base station on a second physical resource, monitors the second physical resource for the UE-specific DCI portion based on at least the information from the common DCI and decodes the UE-specific DCI portion based on at least the information from the common DCI.

Abstract: Embodiments herein describe systems, apparatuses, and methods for adapting physical downlink control channel (PDCCH) monitoring behaviors. In some embodiments, a network node and a UE use search space set group switching to change PDCCH monitoring behavior. In some embodiments, a network node and a UE use PDCCH skipping to change PDCCH monitoring behavior. The PDCCH monitoring behavior may be indicated in a downlink control indicator (DCI).

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) reports beam management information to a network. The UE receives a first group of multiple reference signals from a first transmission reception point (TRP) of a network, receives a second group of multiple reference signals from a second different TRP of the network, selects a first beam associated with one of the multiple reference signals of the first group, selects a second beam associated with one of the multiple reference signals of the second group and transmits a message to the network, the message including an indication of the selected first beam and second beam.

Abstract: Herein described are apparatuses, systems, and methods related to handover operations of user equipment within a wireless network. An apparatus for an evolved NodeB (eNB) may include circuitry to determine one or more candidate eNBs available to provide service to a user equipment (UE) based on cell information received from one or more other eNBs, and generate an autonomous handover (HO) information message for transmission to the UE, wherein the autonomous HO information message includes an indication of the one or more candidate eNBs. The apparatus may further include memory to store the indication of the one or more candidate eNBs. Other embodiments may be described and/or claimed.

Abstract: A user equipment (UE) configures a first search space (SS) set of a first slot group for multi-slot physical downlink control channel (PDCCH) monitoring (MSM) and a second SS set of a second slot group for MSM. The second SS set comprises a first type of common search space (CSS) limited to a maximum number of locations. The UE then performs MSM using the first SS set and the second SS set.

Abstract: The techniques described herein may include solutions for using downlink control information (DCI) to indicate dormancy for secondary cells (SCells). For DCI without a specific field for indicating dormancy for SCells, one or more fields of the DCI may be repurposed to report SCell dormancy. Repurposed fields may be arranged according to radio resource control (RRC) configuration information, a most significant bit (MSB), a least significant bit (LSB), and/or one or more bits being directed to specific SCell dormancy with one or more other bits being directed to SCell group dormancy, subsets of SCells, and/or a pre-defined rule. These and many other features and examples are described herein.
