Wireless communications systems and methods related to improving multiplexing capability in a frequency spectrum are provided. A first wireless communication device obtains a configuration for communicating a communication signal in a frequency spectrum. The configuration is based on at least a number of wireless communication devices scheduled to communicate in a time period.

A higher order intermodulation product, which is co-located with a lower order intermodulation product for the first and second allocations resulting from any respective higher order and lower order transceiver nonlinearities is identified. A determination is then made as to whether the co-located higher order intermodulation products have a region of overlap with the downlink allocation. When the co-located higher order intermodulation products have a region of overlap with the downlink allocation, adjustments in the operation are made to account for the overlap of the higher order intermodulation product and the downlink allocation.

A transmitting device may select frequency domain resources for an alert transmission based on a severity level of the alert transmission. The transmitting device may determine a severity level of an alert transmission to be transmitted on one or more available channels. The transmitting device may determine a presence of one or more systems configured to transmit on one or more neighbor channels of the one or more available channels. The transmitting device may select, for the alert transmission, frequency domain resources within the one or more available channels based on the presence of the one or more systems and the severity level. The frequency domain resources for a highest severity level transmission are spaced further apart from the one or more neighbor channels in the frequency domain than resources for a lower severity level transmission. The transmitting device may transmit the alert transmission on the frequency domain resources.

The method comprises determining, at the terminal device, available resources for a sidelink transmission in a predetermined time period; determining a power level for the sidelink transmission in the available resources; and selecting, from the available resources, a set of target resources for transmitting a signal using the power level. In this way, a low latency feedback is guaranteed and meanwhile a consistent transmission power will be maintained in the duration of the sidelink transmission.

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 at least one of a first set of peak reduction tones (PRTs) for uplink communication, or a second set of PRTs for downlink communication, for use in a full-duplex communication mode. The first set of PRTs and the second set of PRTs may share at least one PRT. The UE may transmit, to the base station, or receive, from the base station, at least one signal based at least in part on the at least one of the first set of PRTs or the second set of PRTs. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. A transmitting device may identify multiple demodulation reference signal (DMRS) symbols corresponding to multiple DMRS ports of a multiple input multiple output configuration. The transmitting device may generate multiple phase-rotated and precoded DMRS symbols by applying an orthogonal cover code, a phase rotation scheme, and a precoding matrix to the identified DMRS symbols. The transmitting device may map the phase-rotated and precoded DMRS symbols to time-frequency resources corresponding to multiple antenna ports, and transmit a DMRS based on the mapped phase-rotated and precoded DMRS symbols. The transmitting device may transmit the DMRS using multiple antennas that correspond to the antenna ports.
