A method for communication between user equipments includes: determining, by a user equipment (UE), a physical control channel resource of a first frequency; and transmitting, by the UE, first control information on a physical control channel of the first frequency; wherein the first control information includes frequency indication information and/or resource indication information of a second frequency, the frequency indication information of the second frequency is used to indicate the second frequency, and the resource indication information of the second frequency is used to indicate an allocated/reserved resource of the second frequency.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to trigger frame and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) PPDU from a wireless station (STA), where the trigger frame carries RU allocation information indicating a number (N) of tones allocated for the STA and carries tone distribution information indicating whether the N tones are allocated for a contiguous transmission or a distributed transmission. In some other implementations, an AP or a STA may transmit a PPDU carrying distributed signaling information indicating whether the PPDU is transmitted as a contiguous transmission or a distributed transmission.

Various schemes pertaining to global cyclic shift delay (CSD) assignment for distributed-tone resource unit (dRU) transmissions in wireless communications are described. An apparatus applies a CSD index assignment in distributing a plurality of subcarriers of a resource unit (RU) over a bandwidth to generate an extremely-high-throughput short training field (EHT-STF) of a dRU. The apparatus then transmits symbols of the EHT-STF of the dRU. The CSD index assignment is based on a dRU hierarchical structure with one or more CSD indexes shared among multiple dRUs of different sizes but not among multiple dRUs of a same size.

A method for carrier aggregation receives a signal with multiple non-contiguous carrier bands. Frequency converting of the signal to a compressed single intermediate frequency band with a pseudonoise code applied to a local oscillation of each of the multiple non-contiguous carrier bands while maintaining separation of the multiple non-contiguous carrier bands permits reduced complexity digital signal processing to detect spectral power density and demodulate waveforms across multiple channels A receiver includes a pseudorandom noise generator applying a pseudo noise code to the local oscillator generator to produce a unique set of spectral tones in the output signal that sample-specific channels over the multiple non-contiguous carrier bands.

Various schemes pertaining to optimization of distributed-tone resource unit (dRU) and distributed-tone multi-resource unit (dMRU) designs for transmission in a 6GHz low-power indoor (LPI) system are described. An apparatus distributes a plurality of subcarriers of a resource unit (RU) to generate a dRU or a distributed-tone multi-RU (dMRU) on an 80MHz frequency segment or subblock. The apparatus then communicates with a communication entity using the dRU or the dMRU.

Apparatuses, methods, and systems are disclosed for determining a maximum power reduction for non-contiguous radio resource allocations. One apparatus includes a processor that receives a non-contiguous resource allocation and calculates a fraction of resource block punctured from a smallest containing contiguous allocation (“SCCA”). Here, the SCCA is the smallest set of contiguous resource blocks that encompasses the non-contiguous resource allocation. The processor determines a first additional maximum power reduction for the non-contiguous resource allocation in response to the fraction of punctured resource blocks being less than a threshold value. The apparatus includes a transceiver that transmits an uplink signal on the non-contiguous resource allocation using the first additional maximum power reduction in response to the fraction of punctured resource blocks being less than the threshold value.

Example embodiments of the invention provide at least a method and apparatus to perform at least determining, by a user equipment of a communication network, information comprising a plurality of frequency ranges of a transmission; receiving, by the user equipment, the plurality of frequency ranges of the transmission distributed over different time slots monitored by the user equipment; and combining, by the user equipment, the received plurality of frequency ranges to derive content of the transmission. Further, to perform at least determining, by a network device of a communication network, information comprising a plurality of frequency ranges of a transmission; and sending, by the network device, to user equipment of the communication network the plurality of frequency ranges of the transmission distributed over different time slots monitored by the user equipment for causing combining at the user equipment to derive content of the transmission.

A base station includes a transmitter configured to transmit a downlink control information to a user equipment, the downlink control information being generated based on one of (1) a first uplink allocation information indicating a first frequency block corresponding to a first plurality of subcarriers which are contiguous in frequency and (2) a second uplink allocation information indicating a second frequency block corresponding to a second plurality of subcarriers which are contiguous in frequency and a third frequency block corresponding to a third plurality of subcarriers which are contiguous in frequency, the second frequency block and the third frequency block being separated in frequency.

This disclosure provides systems, methods, and apparatuses for wireless communication that can be used for channel puncturing. A wireless station (STA) may receive an indication of a first puncturing pattern to be used for transmitting or receiving data over a wireless channel, where the first puncturing pattern is defined by a first wireless communication protocol release and the STA is configured to operate according to a second wireless communication protocol release. The STA may select, from a set of puncturing patterns defined by the second wireless communication protocol release, a second puncturing pattern that includes one or more non-punctured subchannels that are subsets of one or more corresponding non-punctured subchannels of the first puncturing pattern. The STA may use the second puncturing pattern to transmit or receive one or more packets over the wireless channel.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to short training field (STF) designs and signaling that support distributed transmissions. A transmitting device that transmits data on a distributed resource unit (dRU) may transmit an STF sequence over a spreading bandwidth of the dRU according to an existing STF tone plan. Each STA allocated a dRU for transmission in a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) maps its STF sequence to one or more spatial streams and may apply one or more global cyclic shift delays (CSDs) to the STF sequence mapped to the one or more spatial streams, respectively. As such, different global CSDs may be assigned to different STAs so that each STA transmits its STF sequence with different amounts of delay.
