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.

Abstract: A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises a processor configured to receive a first downlink control information (DCI) for scheduling a first physical downlink shared channel (PDSCH). The first DCI includes a non-numerical (NN) value of K1 for hybrid automatic repeat request (HARQ)-ACK feedback. The processor is further configured to determine a first priority class associated with the first PDSCH, and determine K1 value and priority class associated with one or more subsequent PDSCH received from the BS, until a selected PDSCH having a numerical K1 value and a same priority class as the first priority class is identified. Further, the processor is configured to provide HARQ-ACK feedback associated with the first PDSCH using a PUCCH/PUSCH occasion indicated by a second DCI scheduling the selected PDSCH.

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: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises one or more processors configured to select a first resource from a candidate resource set comprising a plurality of candidate resources within a first resource selection window. In some embodiments, the first resource is to be utilized by the UE for a first transmission of a transport block (TB) over sidelink. In some embodiments, a size of the first resource selection window is derived based on a (pre)configured maximum number of retransmissions of the TB. In some embodiments, the one or more processors is further configured to generate a first transmission signal comprising the first transmission of the TB, to be transmitted over the sidelink using the selected first resource.

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 base station (BS) configures a user equipment (UE) with parameters for channel access operations on a shared channel. The BS transmits to the UE a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), wherein the BS-FFP overlaps the UE-FFP, schedules an uplink (UL) transmission during the UE-FFP and when there is no downlink (DL) transmission in the BS-FFP, receiving the UL transmission from the UE during the BS-FFP.

Abstract: A wireless communication system may use enhanced feedback indicating a PDSCH decoding outcome. The enhanced feedback may be in an uplink control information (UCI) and carried over PUCCH or PUSCH. The enhanced feedback may be encoded and divided up into two parts of the UCI. A first payload may be carried in a first part of the UCI and a second payload comprising additional feedback information may be carried in a second part of the UCI.
