    Abstract: Apparatuses, systems, and methods for sounding reference signal (SRS) coverage enhancement. A user equipment device (UE) may receive a configuration for SRS time domain bundling from a base station and may transmit, to the base station, at least one SRS transmission in accordance with the configuration. The configuration may include an indication of (and/or indicate) one or more SRS transmission occasions. The configuration may be communicated via higher layer signaling or physical layer signaling. The RRC parameter may be an SRS-ResourceSet parameter or an SRS-Resource parameter and may include a nrofSlots parameter to indicate the number of slots, where a slot may correspond to an SRS transmission occasion. The MAC CE may include at least four bits indicating the number of slots. The DCI may include at least one field indicating the number of slots.

    Abstract: Techniques discussed herein can facilitate enhanced radio resource management measurements for wireless technology including New Radio (NR). One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive a measurement link information state link information. The one or more processors are further configured to determine, from the measurement link information, a number of synchronization signal block based measurement timing configurations (SMTCs) (Y) per Rx beam of a number of receive (Rx) beams (N); generate at least one of a subset number of Rx beams (NUE) of the number of Rx beams based on the measurement link information, or an increased number of SMTCs (YUE) of the number of SMTCs corresponding to the number of Rx beams; and perform radio resource management (RRM) measurements according to one or more of the subset number of Rx beams or the increased number of SMTCs.

    Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.
