Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) to perform demodulation reference signal (DMRS) enhancement whereby the UE may transmit physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) repetitions with different DMRS densities (e.g., a first DMRS density configuration having a first or default DMRS pattern within a transmission time interval (TTI) that is higher than a second DMRS density configuration having fewer DMRSs than the normal DMRS pattern or no DMRSs within the TTI). The UE may identify TTIs (e.g., slots) that satisfy one or more phase continuity rules, and may perform DMRS enhancement in the identified TTIs, and may restart a mapping sequence indicated in the DMRS mapping pattern at each bundle interval boundary or when consecutive uplink symbol periods within a bundling interval do not satisfy a phase continuity condition.

A user equipment (UE), that is configured for demodulation reference signal (DMRS) bundling, may receive a control message that schedules first and second sets of repetitions of an uplink transmission. The UE may determine a phase coherency configuration to be applied for DMRS transmissions corresponding to each set of repetitions. The phase coherency configuration may be determined based on a phase coherency capability of the UE, and the phase coherency configuration may specify that phase coherency is to be maintained for one or more of the first set of repetitions separate from one or more of the second set of repetitions. The UE may transmit the first set of repetitions with a first set of demodulation reference signals and the second set of repetitions with a second set of demodulation reference signals in accordance with the phase coherency configuration.

Abstract: Methods, systems, and devices for joint sensing and data communication. A first sensing signal and a second sensing signal are transmitted in sequence, from a transmitter and using the same carrier frequency, for combined processing by a receiver. In some implementations, the sensing signals are radar signals. Data communication during an intervening time period between the first sensing signal and the second sensing signal involves the transmitter sending a data communication signal to another device or vice versa. Phase continuity between the first sensing signal and the second sensing signal can be maintained through performing radio frequency (RF) tuning on the transmitter after the transmitter transmits the data communication signal. The RF tuning may involve storing and restoring an operating state of a power amplifier in the transmitter. Alternatively, phase continuity can be maintained through preventing the transmitter from transmitting over an entirety of the intervening time period.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

A user equipment (UE) may receive a configuration for a transmission configuration state for receiving downlink channel transmissions from a base station via a configurable surface. The transmission configuration state may indicate a quasi-co-location source associated with transmission via the configurable surface. The UE may receive a downlink channel transmission via the configurable surface based on the transmission configuration state and the quasi-co-location source. The UE may be capable of determining whether the transmission configuration state conflicts with the quasi-co-location source indicated by the transmission configuration state. The UE may transmit an indication to the base station that the configuration for the transmission configuration state conflicts with the quasi-co-location source. The indication may include a beam failure indication or a measurement report.
