Abstract: Certain aspects of the present disclosure provide techniques for peak to average power ratio (PAPR) reduction for orthogonal frequency division multiplexing (OFDM). An example method, performed at a transmitter, includes generating a plurality of orthogonal frequency division multiplexed (OFDM) symbols, based on a constellation associated with a modulation scheme, adjusting a phase of at least one of the OFDM symbols based on at least one parameter that depends on a non-integer multiple of a phase distance between two points on the constellation, generating a Discrete Fourier Transform spread OFDM (DFT-s-OFDM) waveform based on the OFDM symbols after the adjustment, and transmitting the DFT-s-OFDM waveform to a receiver.

Abstract: Aspects described herein relate to monitoring a control channel search space for downlink control information (DCI) based on at least two DCI formats associated with switching to one or more uplink frequency resources of multiple configured uplink frequency resources, decoding the DCI received in the control channel search space based on one of the at least two DCI formats and according to a size associated with the one of the at least two DCI formats, including decoding a field from the DCI, and switching to the one or more uplink frequency resources indicated in a frequency resource switching table based on the field. Other aspects relate to encoding and transmitting the DCI.

Abstract: Aspects for enabling Multiple-Input-Multiple-Output (MIMO) communications using a plurality of transmitters across at least two supported frequency bands are disclosed. The apparatus may be a user equipment (UE) that includes, for each UE-supported frequency band, a plurality of transmitters capable when configured of coherently transmitting the received information over the frequency band with information to be transmitted to a base station. The apparatus can identify MIMO coherence capability information for the supported frequency bands on a per-band and a per-band combination basis. The apparatus may determine a proposed transmission configuration based on the MIMO capability information and may report, to the base station, the proposed transmission configuration.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques for uplink channel state information (CSI) reporting that supports transmission precoding matrix indicator (TPMI) selection. A user equipment (UE) may receive CSI reference signals (CSI-RSs), and may perform measurements on the CSI-RSs. The UE may transmit an uplink CSI report to a base station based on the measurements. The CSI report may include an indication of a set of one or more candidate TPMIs, rank indicators (RIs), or both. The base station may test the candidate TPMIs, one or more other TPMIs, or both, to received sounding reference signals (SRSs) and select a TPMI for subsequent signaling. The base station may transmit an uplink grant (e.g., via downlink control information (DCI)) indicating the selected TPMI. The DCI may be a single-stage DCI a timeline.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include a user equipment (UE) receiving a first control signal activating a first time window of scheduled resources that includes a set of uplink shared channel occasions. Further, the UE may allocate data to a first subset of the set of uplink shared channel occasions and transmit the data using the first subset. Moreover, the UE may transmit, after transmitting the data using the first subset of the set of uplink shared channel occasions, a second control signal indicating that a second subset of the set of uplink shared channel occasions will be skipped for uplink data transmission by the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information scheduling a physical uplink shared channel (PUSCH) transmission at least partially in a sub-band full duplex (SBFD) resource in connection with a random access channel procedure. The UE may transmit the PUSCH transmission on time and frequency (time-frequency) resources that are associated with a sub-band configuration of the SBFD resource. Numerous other aspects are described.

Abstract: Apparatuses and methods for altitude-dependent measurement and reporting configurations are described. An apparatus is configured to receive, from a network node, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The apparatus is also configured to measure a SSB value for each SSB in the set of SSBs based on the measurement object configuration and an altitude of the UE. An additional apparatus is configured to configure, for a UE, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The additional apparatus is also configured to provide the set of SSBs indicated in the measurement object configuration.

Abstract: In a user equipment (UE) of a wireless communication network, the UE configured to operate in half duplex frequency division duplexing (HD-FDD) mode in the network the UE configures for one or more conditions under which the UE will transmit under HD-FDD mode in uplink (UL) to the network and not receive in downlink (DL) from the network during a Random Access Channel (RACH) procedure. The UE determines whether the configured one or more conditions obtain for a particular RACH procedure. Upon determining that the configured one or more conditions obtain for the particular RACH procedure, the UE transmits under HD-FDD mode in UL during the particular RACH procedure in accordance with the configured one or more conditions.
