Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a wakeup message to awaken a base station from a sleep mode. The method also includes communicating with the base station after the base station awakens. A method of wireless communications by a base station includes entering a sleep mode when no user equipments (UEs) are connected to the base station. The method also includes receiving a signal from a UE to awaken from the sleep mode. The method further includes resuming signal transmissions after waking up from the sleep mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message from a network entity indicating a first set of configuration parameters for tracking reference signals (TRSs) specific to the UE. The UE may monitor for one or more TRSs according to the first set of configuration parameters and during a first time interval. The UE may receive a layer-1 (L1) signal or a layer-2 (L2) signal from the network entity indicating a second set of configuration parameters for the TRSs specific to the UE that are different from the first set of configuration parameters. The UE may transmit an acknowledgement message to the network entity indicating the UE received the L1 signal or the L2 signal. During a second time interval subsequent to the first time interval, the UE may monitor for additional TRSs according to the second set of configuration parameters.

Abstract: The apparatus may be a UE configured to transmit, to a base station, an indication of a UE capability associated with a contiguous FD pilot; receive, from the base station, an indication of an allocation of one or more frequency sub-bands for a reception of one or more contiguous FD pilots; and receive, from the base station, the one or more contiguous FD pilots via the one or more frequency sub-bands. The apparatus may be a configured to receive, from a UE, an indication of a UE capability associated with a contiguous FD pilot; select one or more frequency sub-bands for a transmission of a contiguous FD pilot; transmit, to the UE, an indication of an allocation of the one or more frequency sub-bands for the transmission of the contiguous FD pilot; and transmit, to the UE, the contiguous FD pilot via the one or more frequency sub-bands.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform online spur detection and mitigation scheme. The UE may identify spurs during operation, in real time, and apply cancelation and noise equalization to address identified spurs. The UE may apply a high pass filter to reference signals. During a symbol, the UE may apply the high pass filter by estimating the channel on one or more neighbor tones (e.g., tones of higher frequency and tones of lower frequency that also carry reference symbols). Because the UE may assume that a channel will generally be smooth, and that noise may vary slowly or steadily across frequency resources, the UE may compare the channel noise of a particular tone to an average or normalized channel noise of the one or more neighbor tones.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a warning message comprising a first indication of a priority of the warning message and a second indication that identifies an event. The UE may transmit a repetition of the warning message based at least in part on the first indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described to switch between waveform configurations based on an indicated modulation coding scheme (MCS) such that waveform switching may be signaled implicitly. A base station may configure a user equipment (UE) with a hybrid MCS table including MCS indexes associated with a first waveform configuration and MCS indexes associated with a second waveform configuration. The base station may schedule resources for an uplink transmission for the UE and may indicate an MCS index associated with the uplink transmission, using index from the MCS table. The UE may select a waveform configuration for the uplink transmission based on the MCS index. For example, the UE may compare the MCS index with a threshold MCS index of the hybrid MCS table and determine a waveform configuration associated with the MCS index based on whether the MCS index falls above or below the threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a request for a data transmission that includes multiple subsets of data each associated with a different constellation granularity. In response to the request, the base station may encode the data transmission using multiple different constellation granularities and may transit the encoded data transmission to the UE. For example, the UE may receive the data transmission including a first subset of data that was encoded by the base station using a first constellation granularity and a second subset of data that was encoded by the base station using a second constellation granularity. The UE may then iteratively estimate phase-noises associated with respective subsets of data and perform phase-noise correction operations on the entire data transmission based on the estimated phase-noises.

Abstract: Disclosed are techniques related to wireless communication system in which multi-level encoded modulation (MLCM) is applied to non-coherent communication. In the proposed techniques, a small fraction of differential phase rotations or bits participating in differential symbol coding are protected with strong codes while other complementary differential phase rotations or bits are protected with weaker codes. Compared to conventional non-coherent communication techniques in which a uniform protection is applied to any fraction of differential phase rotation or any bit of a differential symbol, the proposed MLCM approach enables more spectrally efficient scheme.

Abstract: An apparatus for wireless communication includes a transmitter and a receiver. The receiver is configured to receive a first code block (CB) that is associated with a code block group (CBG) and that is included in a transport block (TB). The receiver is further configured to receive a second CB that is associated with the CBG and that is included in the TB. The first CB is distinct from the second CB. The second CB includes at least a first bit that is associated with the first CB.
