Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a synchronization signal/physical broadcast channel (SS/PBCH) block index, associated with an SS/PBCH block, based at least in part on a set of bits included in a payload of a PBCH of the SS/PBCH block, a demodulation reference signal (DMRS) sequence included in the PBCH, a scrambling sequence associated with the PBCH, or an interleaving associated with the PBCH. Numerous other aspects are described.

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: Certain aspects of the present disclosure provide techniques for rate-splitting multiple access (RSMA) for a user equipment (UE) group. An example method includes transmitting, to a group of receiver UEs (Rx UEs), an indication that the Tx UE will transmit to the group of Rx UEs using rate splitting multiple access (RSMA), and transmitting to the group using RSMA, wherein transmitting to the group using RSMA comprises: splitting individual messages intended for individual Rx UEs in the group into common messages and private messages, combining the common messages, transmitting the combined common messages using a first precoder, and transmitting the private messages using separate precoders.

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 wireless communication at a user equipment includes selecting one of a first energy detection threshold and a second energy detection threshold, detecting an energy level, determining that the energy level is less than the selected one of the first energy detection threshold and the second energy detection threshold, and transmitting data after determining that the energy level is less than the selected one of the first energy detection threshold and the second energy detection threshold. In some examples, the first energy detection threshold is for a first duplex mode of operation (e.g., a half-duplex mode of operation), and the second energy detection threshold is for a second duplex mode of operation (e.g., a full-duplex mode of operation).

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: Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes receiving an indication from a base station (B S) that multiplexing of hybrid automatic retransmission request (HARQ) information and channel state information (CSI) is enabled in all physical uplink control channel (PUCCH) resources, generating a first CSI report regarding a first downlink (DL) channel from the BS, multiplexing a HARQ response to a transmission from the BS and the first CSI report in a PUCCH, and transmitting the PUCCH to the BS via one of the PUCCH resources.

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.

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.
