Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARQ) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

Abstract: A method and apparatus for downlink and uplink control management of component carriers during carrier aggregation in a new radio wireless communication system is disclosed. For example, the method and apparatus include receiving, at a user equipment (UE), a slot format indicator in at least one slot of at least one component carrier of a plurality of component carriers from a network entity, where the at least one component carrier includes a group common Physical Downlink Control Channel (PDCCH), the slot format indicator within the group common PDCCH indicating at least slot structure information for one or more other component carriers from the plurality of component carriers; and communicating, with the network entity, using the at least slot structure information for the one more other component carriers.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a user equipment (UE) includes receiving, from a network unit, an indicator indicating dynamic waveform switching between a first waveform type and a second waveform type and monitoring, based on the indicator, for downlink control information (DCI) from the network unit, wherein at least one of a size of the DCI, a size of a bitfield of the DCI, or a location of the bitfield of the DCI is interpreted based on the indicator.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission. As another example, a device may not expect to receive a grant for an uplink transmission that would arise in subsequent cancelation of that uplink transmission due to a previously-received grant or previously-received ULPI.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may accumulate a number of hybrid automatic repeat request (HARQ) bits as a result of one or more resource conflicts and may store the number of HARQ bits for a later transmission opportunity. The UE may transmit a scheduling request that requests resources for a transmission of the number of HARQ bits that are stored at the UE as a result of the number of HARQ bits satisfying a triggering condition. For example, the UE may transmit the scheduling request if a quantity of the number of HARQ bits satisfies a threshold quantity. Additionally or alternatively, the UE may transmit the scheduling request if the number of HARQ bits include triggering content. For example, the UE may transmit the scheduling request if any HARQ bit stored at the UE conveys a negative acknowledgement (NACK).

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit downlink control information (DCI) to a user equipment (UE) indicating a joint field for at least a first component carrier (CC) and a second CC of a carrier aggregation configuration. For example, the joint field may include a rate matching (RM) indication for the first CC and the second CC, a zero power channel state information reference signal (ZP-CSI-RS) indication for the first CC and the second CC, or both. In some cases, the RM indication may include a common RM resource (RMR) configuration applicable for both the first CC and the second CC or per-CC RMR configurations that indicate separate RMRs for each of the CCs. Additionally, the ZP-CSI-RS indication may include a set identifier that indicates a resource set for ZP-CSI-RS resources for both the first CC and the second CC.

Abstract: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.

Abstract: Apparatuses and methods for per-panel PTRS density for panels/sets of antennas of UEs are described. An apparatus is configured to transmit information associated with a PTRS density for each panel of a set of panels associated with the UE; receive, from a network entity, a configuration associated with the PTRS density for each panel of the set of panels; and communicate, based on the configuration, downlink data via a PDSCH or uplink data via a PUSCH based on the PTRS density for one panel in the set of panels, where the PTRS density for the one panel of the set of panels is based on at least one of a MCS or a number of scheduled RBs associated with a PDSCH reception or PUSCH transmission through the one panel. Another apparatus is configured to receive the information, generate and transmit the configuration, and also to communicate via the PDSCH/PUSCH.
