Abstract: Resource selection for communication of uplink control information may include determining cyclic shift ramping for resource block (RB) sets. A user equipment UE) may use one or more RB sets for transmitting uplink control information on a shared radio frequency spectrum such as an unlicensed band. In some examples, the UE may transmit uplink control information to a base station (BS) via consecutive RB sets. To this end, the BS may schedule consecutive RB sets for an uplink transmission by the wireless communication device and monitor each of these RB sets for uplink control information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling which indicates a resource block indicating a number of reference signal tones and data tones in an uplink transmission. In some cases, the UE may determine a first transmission power for the reference signal tones, and a second transmission power for the data tones that is different from the first transmission power. In some other cases, the UE may identify a frequency allocation for the resource block which allocates a same frequency bandwidth for the reference signal tones and the data tones, and the UE may determine a same transmission power for the reference signal tones and the data tones based on the frequency allocation. Based on the determination of transmission powers, the UE may transmit the reference signal tones and the data tones to a base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an operating mode associated with synchronization signal block (SSB) transmission in a band, wherein the operating mode is one of a licensed operating mode or an unlicensed operating mode; and receive one or more SSBs based at least in part on the operating mode. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In a first example, the user equipment (UE) may receive sidelink control information scheduling resources for a sidelink data transmission spanning a set of tones and indicating a demodulation reference signal (DMRS) pattern. The UE may identify that each tone of the set of tones is configured to carry a DMRS for a symbol of the DMRS pattern and may receive the sidelink data transmission based on the symbol of the DMRS pattern carrying the DMRS for each tone. In a second example, the UE may receive control signaling indicating a configuration for a non-overlapping relationship between a first resource for receiving a DMRS and a second resource for receiving a phase tracking reference signal. The UE may receive the DMRS over the first resource and the phase tracking reference signal over the second resource based on the non-overlapping relationship.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, in a control channel, a first grant identifying a first set of resources of a first data channel on which the UE is to monitor for one or more second grants, the first data channel being downlink. The UE may monitor the first set of resources in the first data channel for the one or more second grants, the one or more second grants identifying a second set of resources of a second data channel on which the UE is to perform data communications. The UE may transmit, based at least in part on the monitoring the first set of resources, a feedback message associated with receipt of the one or more second grants.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive a first downlink control message indicating a set of parameters for a scheduling request for the UE. The UE may then receive on a receive beam a second downlink control message, which may be a layer 1 signal, and determine uplink resources for the scheduling request and a transmission configuration indicator state for the scheduling request. The UE may transmit, to the base station, the scheduling request using the uplink resources.

Abstract: Aspects relate to implementing multiplexing with a single carrier waveform. In some examples, intra-symbol multiplexing of data and other information on a single carrier symbol may be implemented utilizing pre-discrete Fourier transform (DFT) multiplexing. In addition, time domain rate-matching may be performed on the data to rate-match the data around the other information based on a number of usable samples in the time domain within the symbol for the data.
