In one example, data in a service data unit (SDU) is processed. The processed data is then transmitted to a receiving entity on at least some resource units. The processing of the data involves (i) performing subcarrier mapping on one or more combinations of multiple RUs of a frequency segment within a predetermined bandwidth by using a joint subcarrier interleaver; or (ii) performing subcarrier mapping on one or more combinations of multiple RUs on multiple frequency segments of the predetermined bandwidth by using multiple subcarrier interleavers.

Description

[0001] This application is a divisional application of the Chinese invention patent application with application number 202011444334.X filed on December 8, 2020 and invention name “Interleaving method for multiple RU combinations in WLAN”. Technical Field

[0002] The present invention relates generally to wireless communications, and more particularly to the combination of multiple resource units (RUs) in an interleaving wireless local area network (WLAN). Background Art

[0003] Unless otherwise indicated, the approaches described in this section are not background art to the claims listed below and are not admitted to be background art by inclusion in this section.

[0004] For next generation WLANs based on the upcoming Institute of Electrical and Electronics Engineers (IEEE) standards (e.g., IEEE 802.11be), a resource unit is defined as a group of subcarriers that are allocated and used for transmission. The size of a RU can be 26, 52, 106, 242, 848, 996, and 2*996 subcarriers with a subcarrier spacing of 78.1 kHz. Accordingly, the number of data subcarriers N for each RU is sd The numbers can be 24, 48, 102, 234, 468 and 980 respectively.

[0005] In order to improve spectrum utilization, IEEE 802.11be allows multiple RUs to be assigned to a single station (STA). Regarding transmission on multiple RUs (multiple RUs), data on multiple RUs for one STA can be transmitted on the physical (PHY) layer of the transmission entity using a physical layer consistency protocol (PLCP) service data unit (PSDU) received from the media access control (MAC) layer of the transmission entity, and the information bits of the multiple RUs are jointly encoded. However, different interleaving schemes for multiple RUs are required to achieve a good trade-off between system complexity and performance. Summary of the invention

[0006] The subsequent overview is illustrative only and is not intended to be limiting in any way. That is, the subsequent overview is provided to introduce the concepts, brightness, benefits and advantages of the novel and non-obvious technologies described herein. Selected embodiments are further described in the detailed description. Therefore, the subsequent overview is not intended to identify the essential features of the claimed subject matter, nor is it intended to determine the scope of the claimed subject matter.

[0007] The purpose of the present invention is to provide a scheme, concept, design, technology, method and apparatus for interleaving a plurality of RUs in a WLAN. Under various proposed schemes according to the present invention, it is believed that the various interleaving schemes proposed herein can be used to achieve a balance between system complexity and performance for the transmission of a plurality of RUs.

[0008] In one aspect, a method involves processing data in a service data unit (SDU). The method may also involve transmitting the processed data to a receiving entity on at least some RUs. When processing the data, the method may involve: (i) performing subcarrier mapping on one or more combinations of multiple RUs within a frequency segment of a predetermined bandwidth by using a subcarrier interleaver; or (ii) performing subcarrier mapping on one or more combinations of multiple RUs on multiple frequency segments of the predetermined bandwidth by using multiple subcarrier interleavers.

[0009] On the other hand, a method may involve processing the data by interleaving the data on at least some of the RUs. The method may also involve transmitting the processed data to a receiving entity. Interleaving the data on at least some of the RUs may include: (i) interleaving one or more combinations of the multiple RUs by using a joint interleaver when the size of each RU of the multiple RUs is less than a predetermined size; or (ii) interleaving the one or more combinations of the multiple RUs by using a joint interleaver in response to the multiple RUs being within a continuous frequency segment of a predetermined bandwidth when the size of each RU of the multiple RUs is greater than or equal to the predetermined size; or (iii) interleaving one or more combinations of the multiple RUs by using multiple subcarrier mappers in response to the multiple RUs being on multiple frequency segments of the predetermined bandwidth. The predetermined size may be 242, and the predetermined bandwidth may be 80 MHz.

[0023] Specific embodiments and implementations of the claimed subject matter are disclosed herein. However, it will be appreciated that the disclosed embodiments and implementations are merely illustrations of the claimed subject matter, which may be presented in various forms. However, the present invention, which requires different forms to be presented, will not be limited to the exemplary embodiments and implementations provided by the present invention. On the contrary, these exemplary embodiments and implementations are provided so that the present invention is thorough and complete and will fully convey the scope of the present invention to those of ordinary skill in the art. In the following description, the details of known features and technologies may be omitted to avoid unnecessary confusion of the presented embodiments and implementations.

[0024] Embodiments according to the present invention relate to various technologies, schemes, solutions and / or solutions for staggered combinations of multiple RUs in WLAN. According to the present invention, many possible solutions can be implemented individually or together. That is, although these possible solutions are described separately below, two or more possible methods can be implemented in the form of one or more combinations. It is worth noting that although the examples described herein and shown in the figures can show a first RU of size A and a second RU of size B, such as RU A+RU B, various proposed solutions according to the present invention can be implemented with RU A+RU B, and vice versa (such as RU B+RU A). In other words, the scope of the present invention is not limited to the examples presented herein, but rather includes various variants thereof. For example, for multiple RU packets (996+484), the order of RUs can be exchanged in different embodiments, for example, a first RU of size 484 plus a second RU of size 996 in one embodiment, or a first RU of size 996 plus a second RU of size 484 in another embodiment.

[0025] Figure 1 An exemplary network environment 100 is shown in which various solutions and approaches according to the present invention may be implemented. Figure 2 to Figure 8 FIG. 1 shows an exemplary embodiment of various proposed solutions in a network environment 100 according to the present invention. Figures 1 to 8 A subsequent description of the various proposed schemes is provided.

[0026] refer to Figure 1 , the network environment 100 may involve a communication entity 110 and a communication entity 120 for wireless communication (e.g., in a WLAN according to one or more IEEE 802.11 standards). For example, the communication entity 110 may be a station (STA) or an access point (AP), and the communication entity 120 may be a STA or an AP. Under various proposed schemes according to the present invention, the communication entity 110 and the communication entity 120 may be used to perform the interleaved combination of multiple RUs described herein.

[0027] Figure 2An exemplary scenario 200 of RU combinations according to an embodiment of the present invention is shown. Scenario 200 shows an example of possible RU combinations of small-sized RUs (e.g., RUs with a size less than 242). More specifically, scenario 200 shows examples of possible RU combinations in 20MHz bandwidth, 40MHz bandwidth, and 80MHz bandwidth. In scenario 200, a combination of small RUs may be limited to 20MHz. Figure 2 , a size 52 RU (or an RU with 52 subcarriers, interchangeably labeled as "RU52") can be combined with a size 26 RU (or an RU with 26 subcarriers, interchangeably labeled as "RU26"). Figure 2 As shown, a RU of size 106 (or a RU with 106 subcarriers, interchangeably referred to as "RU106") can be combined with RU26 (such as in an 80 MHz bandwidth). For simplicity, the term "RUx" in the present invention refers to a RU of size x or a RU with x subcarriers. Figure 2 In the text, the term "DC" stands for direct current.

[0028] In scenario 200, certain combinations of RUs may be permissible under the proposed scheme according to the present invention. For example, one or more pairs of adjacent and non-overlapping RU26 and RU52 may be combined, each pair being separated by one or more unused subcarriers in the frequency domain. Figure 2 Part (A) shows an example of an allowable RU26+RU52 combination under the proposed scheme for a 20 MHz bandwidth, Figure 2 The (B) part is for 40MHz bandwidth, and Figure 2 The (C) portion is used for the 80 MHz bandwidth. In addition, one or more pairs of adjacent and non-overlapping RU26 and RU106 can be combined, each pair being separated by one or more unused subcarriers in the frequency domain. Figure 2 Part (D) shows an example of allowable RU26+RU106 combinations under the proposed scheme for 80 MHz bandwidth.

[0029] In scenario 200, one combination of small RUs may be allowed in each 20 MHz frequency segment. Figure 2 As shown in part (A), there can be a combination of RU26+RU52 in the 20MHz frequency segment, such as Figure 2 As shown in part (B), there can be two combinations of RU26+RU52 in the 40MHz frequency segment, such as Figure 2 As shown in part (C), there are four possible combinations of RU26+RU52 in the 80MHz frequency segment, as well as Figure 2As shown in part (D), there can be four combinations of RU26+RU106 in the 80MHz frequency segment.

[0030] Figure 3 An exemplary scenario 300 of RU combinations according to an embodiment of the present invention is shown. Scenario 300 shows examples of possible RU combinations for large-sized RUs (such as RUs with a size greater than or equal to 242). More specifically, scenario 300 shows examples of possible RU combinations in 80MHz bandwidth, 160MHz bandwidth, 240MHz bandwidth, and 320MHz bandwidth. In scenario 300, for 240MHz bandwidth or 320MHz bandwidth, RU combinations may be based on 160MHz and 80+80MHz. In addition, for 240MHz bandwidth and 320MHz bandwidth, there are three or four or four RU combinations together.

[0031] As defined in current WLAN standards (e.g., IEEE 802.11ax and IEEE 802.11ca), regarding low-density parity-check (LDPC) subcarrier interleaving, after parsing and constellation mapping, each stream has N per orthogonal frequency-width multiple access (OFDM) symbol. SD Quadrature Amplitude Modulation (QAM) symbols. In order to achieve a better trade-off between system complexity and performance, various interleaving schemes for multiple RU combinations are proposed in this article. According to a proposed scheme of the present invention, a joint subcarrier interleaver can be applied to or used for multiple RUs combined within an 80MHz frequency segment. According to the proposed scheme of the present invention, a separate subcarrier interleaver can be applied to or used for multiple RUs or multiple RUs combined in different 80MHz frequency segments. It is worth noting that for multiple RU combinations (such as RU242+RU996, RU484+RU996, (RU242+RU484)+RU996), due to the distance (D TM ) can be only 4, which may not perform joint subcarrier interleaving very well.

[0032] Figure 4 An example scenario 400 of a joint subcarrier interleaving scheme for multiple RU combinations according to an embodiment of the present invention is shown. Scenario 400 shows an example of a joint subcarrier interleaving scheme for multiple RU combinations in an 80MHz frequency segment under the proposed scheme of the present invention. Figure 4In part (A), for small RU combinations (e.g., RU52+RU26 or RU106+RU26), a joint interleaving scheme can be applied. For large RU combinations (e.g., RU242+RU242 and RU242+RU484), when they are in a continuous 80MHz frequency segment, a joint subcarrier interleaving scheme can also be applied. That is, under the proposed scheme, a joint subcarrier interleaver can be applied to or used for all data subcarriers contained in the combined multiple RUs.

[0033] Figure 5 An exemplary scenario 500 of a joint subcarrier interleaving scheme for multiple RU combinations according to an embodiment of the present invention is shown. Scenario 500 shows examples of various interleaving schemes for multiple RUs or multiple RU combinations in different 80 MHz frequency segments. Figure 5 , showing the respective subcarrier interleaving schemes proposed according to the present invention for 160MHz and 80+80MHz.

[0034] Figure 6 An exemplary architecture 600 for interleaving of multiple RU combinations according to an embodiment of the present invention is shown. In the architecture 600, for multiple RUs or multiple RUs combined within an 80MHz frequency segment, the same QAM modulation can be used based on the channel state information (CSI) and clear channel assessment (CCA) results at the transmitter. In the architecture 600, a single interleaver can be utilized.

[0035] Figure 7 An exemplary architecture 700 for interleaving of multiple RU combinations according to the present invention is shown. In the architecture 700, different QAM modulations may be used for RUs or multiple RUs combined in different 80 MHz frequency segments based on the CSI and CCA at the transmitter. In the architecture 700, multiple interleavers may be utilized, each interleaving device corresponding to a respective segment of a different 80 MHz segment. Figure 7 In the example shown, two different interleavers may be used for multiple RUs or combined multiple RUs on two different 80 MHz frequency segments.

[0036] Figure 8 An exemplary architecture 800 for interleaving of multiple RU combinations according to an embodiment of the present invention is shown. In the architecture 800, different QAM modulations may be used for multiple RUs or multiple RUs in different 80 MHz segments based on the CSI and CCA at the transmitter. In the architecture 800, multiple interleavers may be used, each interleaving device corresponding to a respective one of the different 80 MHz segments. Figure 8 In the example shown, four different interleavers may be used for multiple RUs or combined multiple RUs on different 80 MHz frequency segments.

[0040] On the one hand, each processor 912 and processor 922 can be implemented in the form of one or more single-core processors, one or more multi-core processors, one or more RISC processors, or one or more CISC processors. That is, although the singular term "processor" is used herein to refer to processor 912 and processor 922, each processor 912 and processor 922 may include multiple processors in some embodiments and may include a single processor in some other embodiments. On the other hand, each processor 912 and processor 922 can be implemented in the form of hardware (optionally, firmware) having electronic components, including one or more transistors, one or more diodes, one or more capacitors, one or more resistors, one or more inductors, one or more memristors and / or one or more varactors configured and used to implement specific purposes according to the present invention.

For the purpose of illustration and not limitation, a description of the performance of device 910 (such as communication entity 110) and device 920 (such as device entity 120) is provided below. It is worth noting that although exemplary embodiments are provided in the context of WLAN, the same situation can be implemented in other types of networks. Therefore, although the subsequent description of the exemplary embodiments is about the scenario of device 910 as a transmitting device and device 920 as a receiving device, the same situation is also applicable to another scenario of device 910 as a receiving device and device 920 as a transmitting device.
