TECHNICAL FIELD

The present disclosure is generally related to wireless communications and, more particularly, to extremely high coding rates for next-generation wireless local area network (WLAN) systems.

BACKGROUND

Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.

For extreme high-throughput (EHT) systems such as WLAN systems in accordance with the upcoming Institute of Electrical and Electronics Engineers (IEEE) 802.11be standard, 4096-quadrature amplitude modulation (4096-QAM) has been chosen as one of the technologies to achieve the target of extremely high throughput. In current WLAN systems based on one or more of the IEEE 802.11 standards, the highest coding rate is 5/6. Considering up to eight or even sixteen transmit antennas that could be available in an EHT WLAN based on the IEEE 802.11be standard, it may be reasonable to assume that higher coding rate(s) could be operated with transmit beamforming to obtain beamforming gain. Therefore, there is a need for a solution to provide higher coding rates to achieve extremely high throughput in next-generation WLAN systems.

SUMMARY

The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.

An objective of the present disclosure is to provide schemes, concepts, designs, techniques, methods and apparatuses pertaining to extremely high coding rates for next-generation WLAN systems. Specifically, under various proposed schemes in accordance with the present disclosure, new coding rates higher than 5/6, such as 7/8 and 11/12, may be implemented. With such new higher coding rates, overall system throughput may be improved (e.g., by about 5% and 10%, respectively, compared with existing coding rates). Moreover, to reduce complexity in implementation, encoding processes of the new coding rates in accordance with various proposed schemes of the present disclosure may be based on existing low-density parity-check (LDPC) codes as defined in IEEE 802.11n/ac/ax standards by using several new parameters introduced herein. Advantageously, LDPC encoder and decoder designs used in WLAN based on IEEE 802.11n/ac/ax standards may be reused for these new coding rates.

In one aspect, a method may involve coding an input data at a first coding rate using codes designed for coding up to a second coding rate lower than the first coding rate to provide a coded data. The method may also involve wirelessly transmitting the coded data.

It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as, Wi-Fi, the proposed concepts, schemes and any variation(s)/derivative(s) thereof may be implemented in, for and by other types of radio access technologies, networks and network topologies such as, for example and without limitation, Bluetooth, ZigBee, 5thGeneration (5G)/New Radio (NR), Long-Term Evolution (LTE), LTE-Advanced, LTE-Advanced Pro, Internet-of-Things (IoT), Industrial IoT (IIoT) and narrowband IoT (NB-IoT). Thus, the scope of the present disclosure is not limited to the examples described herein.
