Abstract: The present application relates to selecting one or more of activated transmission configuration indicator (TCI) states for communications between a network and a user equipment. In an example, the network includes multiple transmission and reception points (TRPs) with which the UE communications. An activated TCI state can be a unified downlink TCI state that applies to multiple downlink channels or a unified uplink TCI state that applies to multiple uplink channels, where this state has already been activated by the network for the UE. Based on a predefined set of rules or network-based signaling, the UE can determine for a downlink or uplink communication with the network, one or more of the activated TCI states to use to then perform the downlink or uplink communication with the network.

Abstract: Systems, methods, and circuitries are provided for supporting aggregated retransmissions. In one example, a method includes receiving control information that indicates resources including one or more slots for communication of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) transmission that includes at least one PDSCH/PUSCH retransmission A slot group to which a selected one of the one or more slots belongs is identified. The method includes configuring operation to receive the PDSCH transmission or to transmit the PUSCH transmission based on the resources. In response to determining that a PDSCH/PUSCH retransmission of the PDSCH/PUSCH transmission is scheduled for a slot outside the identified slot group, operation is configured to provide hybrid automatic repetition request (HARQ) feedback based on PDSCH/PUSCH retransmissions scheduled for slots within the identified slot group, wherein the HARQ feedback is not based on PDSCH/PUSCH scheduled for slots outside the identified slot group.

Abstract: A user equipment may use a soft acknowledgment/negative-acknowledgement (ACK/NACK) report to indicate a number of desired repetitions for Physical Downlink Shared Channel (PDSCH). In some embodiments, the user equipment may generate a soft ACK/NACK report that includes multiple bits. The multiple bits may be coded to indicate to a network node whether an allocated number of repetitions was sufficient, redundant or insufficient, and how many more repetitions are needed or desire by the UE.

Abstract: A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.

Abstract: Aspects herein relate to wireless devices, circuits, and methods for triggering earlier Channel State Information (CSI) feedback, comprising: transmitting, by a wireless device to a wireless station, an indication to provide earlier CSI feedback (e.g., wherein the indication comprises an indication that the wireless device has a reduced capability to receive messages); receiving from the wireless station, in response to the indication, a modified message (e.g., a Downlink Control Information or modified Medium Access Control Random Access Response), wherein the modified message triggers an earlier CSI feedback from the wireless device; transmitting to the wireless station, in response to receiving the modified message, the earlier CSI feedback using a message related to a RACH procedure (e.g., a Msg3); and completing a connection to the wireless station, e.g., in response to a repeated number of initial access messages broadcast from the wireless station and based on the transmitted CSI feedback.
