Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled. The UE may determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled. Accordingly, in some aspects, the UE may perform channel estimation based at least in part on DMRSs received in different physical downlink control channel monitoring occasions based at least in part on the time domain bundling configuration. Numerous other aspects are provided.

Abstract: To enable HARQ-ACK multiplexing on PUSCH in UL CA, methods, apparatuses, and computer readable medium are provided. An example method includes selecting at least one of a plurality of PUSCHs in which to multiplex one or more UCI bits, one or more of the plurality of PUSCHs being associated with one or more UL grants, the one or more UL grants including one or more UL tDAI values. The example method further includes transmitting, to a network entity, the one or more UCI bits that are multiplexed with the at least one of the plurality of PUSCHs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node and prior to transmission of a radio resource control (RRC) connection request message, a phase tracking reference signal (PTRS) indication that indicates a presence of a PTRS. The UE may transmit the RRC connection request message comprising the PTRS based at least in part on the PTRS indication. Numerous other aspects are described.

Abstract: Aspects relate to wireless communication including the provision of the ability of a user equipment (UE) to indicate the capability of the UE for demodulation reference signal (DMRS) bundling and/or joint channel estimation (JCE). In aspects, the capability indication includes using at least a physical random access channel (PRACH) to indicate the capability of a UE for repeated transmission of the physical uplink shared channel (PUSCH) carrying a connection message, and counting of available slots that are used for the repeated transmission of the physical channel. Additionally, the UE may be configured to indicate the capability for JCE through a demodulation reference signal (DMRS) configuration or a DMRS port.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that an uplink demodulation reference signal (DMRS) bundling operation associated with a physical channel has started. The UE may change an activity state of a reception operation associated with periodic downlink communications based at least in part on determining that the uplink DMRS bundling operation has started. Numerous other aspects are described.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication. The apparatus applies a processing timeline for multiplexing uplink control information (UCI) in at least one slot of a multiple slot physical uplink shared channel (PUSCH) transmission. The apparatus transmits the multiple slot PUSCH transmission with multiplexed UCI based on the processing timeline being satisfied.

Abstract: Certain aspects of the present disclosure provide techniques for mapping time domain positions for a demodulation reference signal (DMRS). A method that may be performed by a user equipment (UE) includes identifying time domain positions for a DMRS to be transmitted with a transport block (TB) sent across multiple slots and transmitting the TB across the multiple slots with the DMRS in the time domain positions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a first UCI bit multiplexed with a second UCI bit, the first UCI bit having a first sequence applied and the second UCI bit having a second sequence, that is orthogonal to the first sequence, applied. The UE may transmit the UCI message. Numerous other aspects are described.
