Various schemes pertaining to distributed-tone resource unit (RU) operation in 6 GHz low-power indoor (LPI) systems are described. A communication entity distributes frequency tones of a resource unit (RU) over a distribution bandwidth as a distributed-tone RU (dRU). The communication entity then communicates using the distributed-tone RU in a 6 GHz low-power indoor (LPI) system. In some cases, the dRU is distributed over an entire bandwidth. Alternatively, the dRU operation is implemented per frequency segment. Alternatively, the dRU co-exists with regular or localized RU.

A user equipment executes carrier aggregation using a plurality of component carriers allocated in a predetermined band in a predetermined frequency range (FR2). In a case where only a plurality of secondary component carriers is allocated in the predetermined band, the user equipment selects a secondary component carrier that is a reception quality measurement target among the plurality of secondary component carriers. In addition, the user equipment transmits a reception quality measurement result.

Various schemes pertaining to subcarrier indices for distributed-tone resource units (RUs) in 6 GHz low-power indoor (LPI) systems are described. A communication entity distributes frequency tones of a RU over a distribution bandwidth as a distributed-tone RU (dRU). The communication entity also generates generating a plurality of subcarrier indices for the distributed-tone RU such that a distribution of the distributed-tone RU is symmetric or asymmetric to a direct-current (DC) tone along an axis of subcarrier indices. The communication entity then communicates wirelessly using the distributed-tone RU in a 6 GHz LPI system.

A method and apparatus are provided. an indication of a first uplink resource allocation of resource blocks for a transmission on a first carrier, and an indication of a second uplink resource allocation of resource blocks for a transmission on a second carrier are received. An indication of a downlink allocation for receiving a downlink signal is further received. 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.

An extremely high-throughput (EHT) station (STA) may encode an EHT PPDU for transmission on a plurality of subchannels. The EHT STA may determine a spectral mask to apply to the EHT PPDU prior to transmission of the EHT PPDU. When preamble puncturing is performed, the EHT STA may apply an overall spectral mask to the EHT PPDU prior to transmission. The overall spectral mask may be based on an interim spectral mask and a preamble-puncture spectral mask. The subchannels may be in a 6 GHz band and the EHT STA may determine if preamble puncturing is to be performed for one or more of the subchannels based on a presence of incumbents in the one or more of the subchannels, although the scope of the embodiments is not limited in this respect.

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.

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.

Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a first beamformed transmission associated with a directional beam from another UE. The UE may measure a main lobe or at least one side lobe associated with the directional beam, and determine a level of interference at the UE based on the measuring. One or more of the main lobe or the at least one side lobe associated with the directional beam may cause interference to a second beamformed transmission associated with another directional beam from a base station. The UE may transmit a beam report including an indication of the main lobe or the at least one side lobe associated with the directional beam causing the interference to the second beamformed transmission associated with the other directional beam from the base station.
