Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.

Abstract: Aspects for MAC-CE duplication for packet repetition in uplink and downlink are disclosed. In one particular aspect a method of wireless communication includes receiving, by a user equipment (UE), a message including a component carrier (CC) identifier (ID) for a particular Medium Access Control (MAC) control element (MAC-CE). The method also includes receiving, by the UE, a first MAC-CE via a first CC of a plurality of CCs, and receiving, by the UE, a second MAC-CE via a second CC of the plurality of CCs. The CC ID included in the message corresponds to a CC ID for the second MAC-CE. The method further includes combining, by the UE based on the CC ID for the second MAC-CE, a first signal corresponding to the first MAC-CE and a second signal corresponding to the second MAC-CE to generate a combined signal for decoding.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may identify a hybrid automatic repeat request (HARQ) process, from one or more HARQ processes configured for a delay-constrained time cycle, for a data communication received from a transmitter in the delay-constrained time cycle. A quantity of the one or more HARQ processes may be based at least in part on a quantity of data communications that the receiver is to receive from a transmitter during the delay-constrained time cycle. The receiver may transmit, to the transmitter and based at least in part on the data communication, HARQ feedback associated with the HARQ process. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a trigger to transmit a physical random access channel (PRACH) transmission on a primary cell or primary secondary cell. The UE may determine a transmit power for the PRACH transmission based at least in part on a type of the trigger to transmit the PRACH transmission. The UE may transmit the PRACH transmission using the transmit power on the primary cell or the primary secondary cell. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that beam measurement resources, associated with performing beam management, are to be activated, and may transmit an activation signal associated with requesting activation of the beam measurement resources. In some aspects, a base station may receive an activation signal associated with requesting activation of beam measurement resources associated with performing beam management, wherein the activation signal is transmitted by a user equipment, and may activate one or more of the beam management resources based at least in part on the activation signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a frequency resource for a multicast/broadcast service (MBS) for the UE to monitor for one or more group-common downlink control channels. The base station may transmit an indication, such as an explicit indication, of a monitoring condition for the group-common downlink control channels within the frequency resource. The UE may apply the monitoring condition by enabling or disabling the group-common downlink control channel monitoring within the frequency resource. The UE may monitor one or more downlink control channels for scheduling information from the base station according to the monitoring condition.

Abstract: Methods, systems, and devices for wireless communications are described, in which temporary reference signals may be configured for use in secondary cell (SCell) activation. A user equipment (UE) may perform wireless communications with a first serving cell supported by a base station, and may receive an indication that a SCell is to be activated. As a result of activation of the SCell, the UE may perform one or more measurements on a reference signal of the SCell that is being activated. The one or more measurements may be performed on a temporary reference signal of the SCell that has one or more parameters that are indicated to the UE with the SCell activation information. The one or more parameter may be indicated by downlink control information (DCI), one or more medium access control (MAC) control elements, implicit signaling, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to bundle reference signals, such as demodulation reference signals (DMRSs), by maintaining one or more coherence properties across DMRSs. A base station may transmit an indication of a DMRS bundling configuration to the UE, and the UE may transmit a DMRS bundling capability indication to the base station. The base station may transmit DCI to the UE, and the UE may determine whether to maintain or alter DMRS bundling (for example, maintain or alter one or more coherence properties) for one or more physical shared channels based on the DCI. The UE may maintain or alter one or more coherence properties of the one or more physical shared channels based on determining whether to maintain DMRS bundling and may transmit the one or more physical shared channels and associated DMRSs to the base station.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals and beam selection are provided. In one aspect, a method of wireless communication is performed by a UE and includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell. The method further includes receiving, from the BS via the second cell during a cell activation period, a first reference signal different from a synchronization signal block (SSB) based on beam information. The method further includes performing a first measurement of the first reference signal, and operating in the second cell based on the first measurement.
