Abstract: Methods and apparatus are provided for structured resource allocation signaling. In one novel aspect, an 8-bit RU allocation filed is allocated in the HE-SIG-B common field for each 20 MHz. The structured resource signaling supports more than four MU-MIMO users. In one embodiment, the STA decodes the 8-bit RU allocation signal following a structured resource unit (RU) allocation rule, and determines the RU. In one embodiment, the STA decodes the first two bits of the 8-bit RU allocation signal to determine a first category of the RU allocation. The categories of the RU allocation includes a large RU size category indicating larger than or equal to 20 MHz RUs exist, a two 106-tone category indicating two 106-tone RUs exist, and a no-large-RU category indicating only smaller-than-242-tone RUs exist. The STA further decodes based on the category. A lookup table (LUT) for RU allocation is built and decoded based on a structured signaling rule.

Abstract: Techniques pertaining to transmission methods for hybrid power modes in 6 GHz frequency band in wireless communications are described. An apparatus (e.g., station (STA)) generates one or more resource unit (RUs). The apparatus then communicates wirelessly using the one or more RUs with a hybrid of power modes.

Abstract: Techniques pertaining to multi-user multiple-input-multiple-output (MU-MIMO) transmission with mixed bandwidths and unequal modulation (UEQM) in wireless communications are described. An apparatus allocates a plurality of resource units (RUs) to a plurality of stations (STAs). The apparatus then performs mixed-bandwidth MU-MIMO communications with the plurality of STAs using the plurality of RUs.

Abstract: Various schemes pertaining to center 996-tone resource unit (RU996) tone plan designs for wide bandwidth 240 MHz in wireless communications are described. A communication entity generates at least one 996-tone resource unit (RU996). The communication entity then communicates wirelessly using the at least one RU996 in a 240 MHz bandwidth. The at least one RU996 includes a center RU996 that is centered around five or more direct-current (DC) tones.

Abstract: Techniques pertaining to signaling and padding methods for probabilistic shaping quadrature amplitude modulation (QAM) transmission in wireless communications are described. An apparatus (e.g., station (STA)) generates a packet using a probabilistic shaping (PS) 4096 quadrature amplitude modulation (4096QAM) such that a length of the packet is extended. The apparatus then transmits the packet in a wireless communication.

Abstract: Various schemes pertaining to short training field (STF) sequence design for wide bandwidths in wireless communications are described. A processor of an apparatus generates an STF of a physical-layer protocol data unit (PPDU) by using a predefined STF base sequence. The processor then performs a wireless communication in a 240 MHz, 480 MHz or 640 MHz bandwidth with the PPDU.

Abstract: A new lower density parity check (LDPC) tone mapper is proposed when DCM is applied for a given resource unit (RU) when LDPC is used as the channel control coding. For HE PPDU transmission with DCM, LDPC encoded streams are first modulated by a DCM constellation mapper. The modulated symbols of the lower half of the frequency segment and the modulated symbols of the upper half of the frequency segment are modulated using the same LDPC encoded bits using DCM mapping. The modulated symbols of the lower half of the frequency segment are mapped to lower half of the data subcarriers using DCM LDPC tone mapper. The modulated symbols of the upper half of the frequency segment are mapped to upper half of the data subcarriers using the same DCM LDPC tone mapper. Maximum frequency diversity for DCM can be achieved.

Abstract: Techniques pertaining to distributed-tone resource unit (DRU) optimization to improve spectrum mask in wireless communications are described. An apparatus (e.g., a station (STA)) generates a DRU according to a tone plan. The apparatus also applies a first shift and a second shift to tones of the DRU in a first half of the tone plan and tones of the DRU in a second half of the tone plan, respectively. The apparatus then performs a wireless communication with the DRU.
