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: Systems and method are provided for determining access link direction beams for smart repeaters (SMRs). An SMR may be configured with a set of SMR transmission beam indicator (TBI) state (SMR-TBI State) configurations. The SMR-TBI State configurations in the set respectively comprise an SMR-TBI State identifier (ID), a cell index, and a reference signal associated with a beam for an access link between the SMR and a user equipment (UE). The SMR may receive, through a backhaul link from a base station, an indication of one or more active SMR-TBI States. For at least one of the one or more active SMR-TBI States, the SMR may forward a signal between the base station and the UE using the beam associated with the reference signal in a corresponding SMR-TBI State configuration.

Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: Embodiments of the present disclosure relate to Physical Uplink Control Channel (PUCCH) reliability enhancement. According to embodiments of the present disclosure, a processor of a UE receives, from a BS associated with a first TRP and a second TRP, a first message for configuring a PUCCH resource to be used by the UE to perform a PUCCH transmission with the BS. In this case, the first message indicates a first configuration corresponding to the first TRP and the first configuration comprises at least one power control parameter associated with the first TRP. The message further indicates a second configuration corresponding to the second TRP and the second configuration comprises at least one power control parameter associated with the second TRP. The processor performs the PUCCH transmission with the BS via the first and second TRPs based on the first message. In this way, the reliability and robustness of the PUCCH transmission for multiple TRP is enhanced.
