Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communications, and more specifically, to a communication method and a communication device in wireless communications. BACKGROUND

[0002] IEEE(Institute of Electrical and Electronic Engineers) established TG(Task group) IEEE802.11be to study the next generation (IEEE802.11a / b / g / n / ac) Wi-Fi technology, the scope of the study is: 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, etc., and it is expected to improve the speed and throughput by at least four times compared with the existing IEEE802.11ax standard, and the main application scenarios are video transmission, AR(Augmented Reality), VR(Virtual Reality), etc.

[0003] The aggregation and coordination of multiple frequency bands means that the devices simultaneously communicate in the frequency bands of 2.4GHz, 5.8GHz and 6-7GHz. For the devices to communicate in multiple frequency bands simultaneously, a new MAC(Media Access Control) mechanism needs to be defined to manage it. In addition, it is also expected to support low-latency transmission in IEEE802.11be.

[0004] In the discussion of IEEE802.11be standard, the maximum bandwidth supported is 320MHz (160MHz+160MHz), and in addition, 240MHz (160MHz+80MHz) and the bandwidth supported in IEEE802.11ax standard may also be supported.

[0005] In IEEE802.11be standard, TSN(time sensitive network) data transmission will be supported, and its latency is generally required to be less than or equal to 1ms; or AR / VR data transmission is supported, and its latency is generally required to be between 1ms and 10ms; in addition, for interactive video or automatic driving control data transmission, its latency is generally between 10ms and 50ms.

[0006] In the existing standard (for example, the IEEE 802.11ax standard), a trigger frame is used to allocate uplink transmission resources to users. In the existing standard (for example, the IEEE 802.11ax standard), for stations (STAs: stations) that do not obtain uplink resources, a mechanism of UORA (uplink OFDMA random access) is used to access resources, and each station randomly selects a single RU (single resource unit) at a time.

[0007] However, in the IEEE 802.11be standard, a MRU (Multi RU) can be allocated to a station supporting the IEEE 802.11be standard at a time, and therefore, the existing mechanism cannot meet the requirements in the IEEE 802.11be standard. SUMMARY

[0022] The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the appended claims and their equivalents. Various embodiments of the present disclosure include various specific details, but these specific details are to be considered only as examples. In addition, for the sake of brevity and clarity, descriptions of well-known functions and constructions can be omitted.

[0023] The terms and words used in the present disclosure and the exemplary embodiments are not limited to the bibliographical meanings, but are used merely to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the description of various embodiments of the present disclosure is provided only for illustration and explanation, and not for the purpose of limiting.

[0024] It will be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

These terms are only used to distinguish one element from another. Thus, a first element discussed below could be termed a second element without departing from the teachings of the example embodiments.

[0026] It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present. In addition, the use of "connected" or "coupled" herein also includes wireless connection or wireless coupling. As used herein, the term "and / or" or the expression "at least one of A or B" includes any and all combinations of one or more of the associated listed items.

[0027] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

[0028] Figure 1 is an exemplary diagram illustrating a wireless communication scenario.

[0029] In a wireless local area network, a basic service set (BSS) can be formed by an access point (AP) and one or more stations (STAs) that communicate with the AP. It will be understood that a station (STA) can also be referred to as a non-AP (non-AP) device. A basic service set can be connected to a distribution system (DS) through its AP, and then access another basic service set to form an extended service set (ESS).

[0030] An AP is a wireless switch for a wireless network and is a core of the wireless network. The AP device can be used as a wireless base station and is mainly a bridge for connecting a wireless network and a wired network. With such an access point AP, wired and wireless networks can be integrated.

[0031] As an example, the AP can include a software application and / or circuitry to enable other types of nodes in the wireless network to communicate with the wireless network both externally and internally through the AP. For example, the AP can be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0032] As an example, a station (STA) can include, but is not limited to, a cellular phone, a smart phone, a wearable device, a computer, a personal digital assistant (PDA), a personal communication system (PCS) device, a personal information manager (PIM), a personal navigation device (PND), a global positioning system, a multimedia device, an Internet of Things (IoT) device, etc.

[0033] Although one AP and three stations (STA1, STA2, STA3) are shown to communicate in Figure 1 However, this is merely exemplary, and embodiments of the disclosure are not limited thereto, for example, the AP and the stations can have any number and / or any type.

[0034] In order to be able to support the requirements of the IEEE 802.11be standard, embodiments of the disclosure redefine information for the UORA mechanism while being able to satisfy a communication environment in which IEEE 802.11be stations (hereinafter referred to as "IEEE 802.11be stations") and IEEE 802.11ax stations (hereinafter referred to as "IEEE 802.11ax stations") coexist. Although only the coexistence of IEEE 802.11be stations and IEEE 802.11ax stations in the communication environment is described herein, embodiments of the disclosure are not limited thereto, for example, there can also be stations supporting the IEEE 802.11ac standard or the like.

[0035] Figure 2 is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The illustrated communication method can be applied to an access point.

[0036] Referring to Figure 2In step 210, the first message frame can be determined. In embodiments of the present disclosure, there can be many ways to determine the first message frame, for example: the access point can generate the first message frame according to at least one of the following: network conditions, load conditions, hardware capabilities of the transmitting / receiving device, service type, relevant protocol provisions; embodiments of the present disclosure do not make specific limitations thereon. In embodiments of the present disclosure, the access point can also obtain the first message frame from an external device, and embodiments of the present disclosure do not make specific limitations thereon.

[0037] The first message frame can be used to allocate resource units for uplink transmission of the user. According to embodiments of the present disclosure, the first message frame can be a trigger frame, but the present disclosure is not limited thereto, and other frames for resource allocation are also feasible. In the following, in order to facilitate description, the first message frame is described by taking the trigger frame as an example.

[0038] For example, the trigger frame used to allocate uplink transmission resources for the user can have an exemplary format as shown in Table 1 below:

[0039] Table 1. Trigger frame format

[0040]

[0041] An exemplary format of a user information field (User Info) in Table 1 can be as shown in Table 2 below:

[0042] Table 2. User information field format

[0043]

[0044] The association identifier (AID 12) in Table 2 defines the case of allocating resource units for the user. An exemplary encoding of AID 12 can be as shown in Table 3 below:

[0045] Table 3. AID 12 subfield encoding

[0046]

[0047] Referring to Table 3, when the encoding in AID 12 is 0 or 2045, it indicates that the User Info field can be used for the station to randomly select resource units. In the description of embodiments of the present disclosure, the associated station (associated STA) refers to a station that has established an associated connection with the AP, has buffered data but has not obtained uplink transmission resources; the unassociated station (unassociated STA) refers to a station that has not established an associated connection with the AP, has buffered data but has not obtained uplink transmission resources.

[0048] The information of RA-RU can be identified by the RA-RU (RU for random access) information subfield in the User Info field (Table 2) for the station to make random selection of resource units, and an exemplary format thereof can be shown in Table 4 as follows:

[0049] Table 4. Format of RA-RU information subfield

[0050]

[0051] It can be understood that each element in the table of the present disclosure exists independently, and these elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time according to the table. The value of each element is independent of the value of any other element in Table 1. Therefore, those skilled in the art can understand that the value of each element in the table of the present disclosure is an independent embodiment.

[0052] The Number of RA-RU subfield indicates the number of consecutive RUs allocated for UORA. The value of the Number of RA-RU subfield is equal to the number of consecutive RA-RUs minus 1. The More RA-RU subfield is set to 1 to indicate that in this User Info field, the RA-RU type indicated by the AID 12 subfield is allocated (exists) in the trigger frame sent later until the end of the TWT SP carrying this field. Otherwise, the More RA-RU subfield is 0. If the More TF subfield of the “Common Info” field in Table 1 is set to 0, the “More RA-RU” subfield is reserved.

[0053] In the UORA mechanism, the AP specifies the range of random numbers for the station by using the OFDMA contention window (OCW: OFDMA contention window) field, and then makes random selection of resource units based on the random number selected by the station in the range and the Number of RA-RU in the trigger frame sent by the AP. The UORA mechanism is not described in detail in the embodiments of the present disclosure to avoid unnecessarily obscuring the inventive concept of the present disclosure.

[0054] According to an embodiment of the disclosure, the first message frame can include at least one of first information and second information, wherein the first information indicates information of a single type resource unit for random access, and the second information indicates information of a composite resource unit for random access. For example, a single type resource unit for random access (RA-RU) can be 26-tone (subcarrier), 52-tone, 106-tone, 242-tone, 484-tone, 996-tone, etc. According to an embodiment of the disclosure, examples of a composite resource unit for random access (RA-MRU) can be 52+26 tone, 106+26 tone, 106+52 tone, 484+242 tone, 996+484 tone, 996+484+242 tone, 2x996 tone, 4x996 tone, 2x996+484 tone, 3x996 tone, 3x996+484 tone, etc.

[0055] In particular, the first information can be the content as shown in Table 2 and Table 3 above, for example, the AID12 subfield in Table 2 and the RA-RU information subfield in Table 3, which are used to allocate single type resource units for associated stations or unassociated stations. In an embodiment of the disclosure, the second information can be extended to include allocation of composite resource units for associated stations or unassociated stations. For example, the RA-MRU (composite resource unit for random access) information subfield can be extended using the variable field in Table 2. It will be understood that the first message frame can include both the first information and the second information, or only one of the two. For example, when single type resource units are allocated for all stations (IEEE 802.11be stations and IEEE 802.11ax stations), the first message frame can include only the first information, and when only composite resource units need to be allocated for IEEE 802.11be stations, the first message frame can include only the second information.

[0056] The first message frame according to an embodiment of the disclosure can be identified (parsed) by IEEE 802.11be stations and can be identified (parsed) by IEEE 802.11ax stations, thereby being applicable to a communication environment in which IEEE 802.11be stations and IEEE 802.11ax stations coexist.

[0057] According to an embodiment of the disclosure, the second information can include a first identifier and a second identifier, for example, the RA-MRU information subfield as shown in Table 5 below.

[0058] Table 5. RA-MRU Info subfield

[0059]

[0060] According to an embodiment of the present disclosure, the first identification indicates the number of composite resource units for random access, for example, the "Number of RA-MRU" in Table 5. In one embodiment, the number of composite resource units for random access can correspond to the number of continuous composite resource units, and in another embodiment, the number of composite resource units for random access can correspond to the number of discontinuous composite resource units. The access point can decide and inform the station of the relevant information of the composite resource units according to its hardware capability, communication environment, etc.

[0061] In one embodiment, each composite resource unit for random access can be composed of at least two single-type resource units, for example, 52+26 tones, 106+26 tones, 106+52 tones, 484+242 tones, 996+484 tones, 996+484+242 tones, 2x996 tones, 4x996 tones, 2x996+484 tones, 3x996 tones, 3x996+484 tones, etc.

[0062] According to an embodiment of the present disclosure, the second identification can indicate whether the composite resource units for random access are included in the second message frame sent after the first message frame of step 210, for example, the "More RA-MRU" in Table 5.

[0063] According to an embodiment of the present disclosure, the second information can further include a third identification. Specifically, the third identification can indicate which type of station randomly selects the composite resource units for random access, for example, the third identification can be an encoding value in AID 12. The third identification will be described in detail later in Case II below.

[0064] Since the IEEE 802.11ax station only randomly selects single-type resource units, and for the IEEE 802.11be station, it can randomly select single-type resource units or randomly select composite resource units, therefore, the following will mainly describe in detail the example of the first message frame when the access point allocates resource units for the IEEE 802.11be station. In an embodiment of the present disclosure, the case of coexistence of IEEE 802.11be stations and IEEE 802.11ax stations is considered.

[0065] I. The IEEE 802.11be station randomly selects one single-type resource unit

[0066] In this case, the information shown in Tables 1 to 5 can be reused, i.e. the single type resource units are allocated to the associated or unassociated stations using the first information in the first message frame (e.g. using the User Info, AID 12 and Number of RA-RU defined in Tables 1 to 4 above). When the stations receive the first message frame, the random selection of the single type resource units can be made according to the first information.

[0067] That is, in the case where the IEEE 802.11be stations randomly select one single type resource unit, the same format of the User Info field in the IEEE 802.11ax standard is used for RU allocation to the stations associated with the AP or not associated with the AP (not obtaining the uplink resource), and then the stations randomly select one RU.

[0068] II. IEEE 802.11be stations randomly select one composite resource unit

[0069] In this case, the composite resource units can be allocated to the associated or unassociated stations using the second information in the first message frame. When the stations receive the first message frame, the random selection of the composite resource units can be made according to the second information.

[0070] According to embodiments of the present disclosure, in order to avoid resource waste, preferably, the composite resource unit for random access can be in a bandwidth of 160 MHz, 240 MHz, 160+160 or 320 MHz, however, this is only exemplary, and other sizes of bandwidths are also feasible.

[0071] As mentioned above, each composite resource unit for random access is composed of at least two single-type resource units. According to an embodiment of the present disclosure, the composite resource units for random access can be divided into small size composite resource units (e.g., 52+26 tones, 106+26 tones, 106+52 tones, etc.) and larger size resource units (e.g., 484+242 tones, 996+484 tones, 996+484+242 tones, 2x996 tones, 4x996 tones, 2x996+484 tones, 3x996 tones, 3x996+484 tones, etc.). Considering that the larger size composite resource units occupy a large amount of bandwidth, resource waste can be caused when used for random access, therefore, when the access point allocates composite resource units for associated stations or unassociated stations, the larger size composite resource units are not allocated for stations to randomly select, and only the small size composite resource units are allocated for stations to randomly select. In one embodiment, in each composite resource unit for random access, each single-type resource unit constituting the composite resource unit has a number of subcarriers less than or equal to a fifth value. According to an embodiment of the present disclosure, the fifth value is a value determined according to the bandwidth occupied by the resource unit, for example, the fifth value can be 106, however, this is only exemplary, and embodiments of the present disclosure are not limited thereto.

[0072] According to an embodiment, the composite resource units for random selection can be carried in the first message frame (e.g., RU allocation subfield), and a plurality of composite resource units for stations to randomly select can be allocated by index numbering of the composite resource units under various bandwidths. The access point and the stations can learn the index numbering of the composite resource units in various ways, for which the present disclosure is not specifically limited.

[0073] In one embodiment, for associated stations, the access point can allocate a plurality of MRUs for stations to randomly select. In this example, in response to the stations being associated with the access point, the first identification (Number of RA-MRU in Table 5) in the first information can be set to a first value to indicate that the number of composite resource units for random access is greater than 1. That is, in this example, the first identification (Number of RA-MRU in Table 5) being set to the first value can indicate that there are a plurality of MRUs for stations to randomly select.

[0074] In another embodiment, the access point can assign one or more MRUs for the unassociated station to randomly select from. In this example, the first identification in the first information (Number of RA-MRU in Table 5) can be set to a second value to indicate that the number of composite resource units for random access is equal to or greater than 1 in response to the station not being associated with the access point. That is, in this example, the first identification (Number of RA-MRU in Table 5) being set to the second value can indicate that there is one or more MRUs for the station to randomly select from. In addition, as another embodiment, the access point can also assign single type resource units to the unassociated station using the first information, which can be referred to in the description of Tables 1-5, and the repeated description is omitted here for brevity.

[0075] The first value or the second value of the first identification can be determined according to the hardware capability of the AP or the communication environment, for which embodiments of the present disclosure are not limited.

[0076] When the access point assigns composite resource units to the associated station and the unassociated station, the third identification (e.g., AID) in the second information can be additionally defined to indicate which type of station randomly selects the composite resource unit for random access.

[0077] In one embodiment, when the access point assigns composite resource units to the associated station (i.e., in the case that the station for random access is the station associated with the access point), the third identification can be set to a third value, wherein the third value is different from the associated identification value set for the single type resource unit for random access. That is, when the access point assigns composite resource units to the associated station, a new encoding value can be defined in the third identification (AID 12) to correspond to the composite resource unit MRU, i.e., the new encoding value defined in the third identification (AID 12) can be different from 0, 1-2007 and 2045 in Table 3, for example, the third value set for the third identification (AID 12) can be 2047, it will be understood that this is only exemplary, embodiments of the present disclosure are not limited thereto, other values that can distinguish between station types and resource types are also feasible.

[0078] In another embodiment, the third identification (AID 12) can be set (encoded) to a fourth value different from the third value when the access point allocates the composite resource unit to an unassociated station (i.e., in the case that the station performing random access is an unassociated station). In one embodiment, the fourth value can be different from the third value and also different from the associated identification value set for the single type resource unit for random access when the access point allocates the composite resource unit to an unassociated station. In another embodiment, the fourth value can be different from the third value but reuse the format in Table 3 when the access point allocates the composite resource unit to an unassociated station, i.e., the fourth value can be the same as the associated identification value set for the single type resource unit for random access, e.g., 2045 in Table 3.

[0079] That is, in the case that the IEEE 802.11be station randomly selects one composite resource unit, multiple MRUs can be allocated for the associated station for the station to randomly select, while one or more MRUs can be allocated for the unassociated station for the station to randomly select, with the principle that: 1, considering the larger size MRU or occupying a large amount of bandwidth, it is not allocated to the unassociated & associated station; 2, the small size MRU is allocated to the associated station, and the single RU is allocated to the unassociated station, and the specific format can be as shown in Table 5 above.

[0080] As an example, in the first message frame (e.g., trigger frame), the value of the custom AID is defined to correspond to the associated station and the unassociated station, for example, AID = 2047 identifies the associated station.

[0081] As an example, the format of RA-MRU Info: under the bandwidth of 160MHz, 240MHz or 160+160 / 320MHz, multiple small size MRUs can be allocated to an associated station, and the specific format can be as shown in Table 5 above. Referring to Table 5, as an example, the number of RA-MRU identifies the number of consecutive MRUs allocated, and the more RA-MRU indicates whether the RA-MRU is contained in the next trigger frame.

[0082] As an example, for the unassociated station, the format of the IEEE 802.11ax standard can be reused, and only one RA-RU is allocated, which corresponds to AID = 2045.

[0083] Referring back to Figure 2In step 220, the first message frame determined in step 210 can be sent to, for example, the station. As described above, upon receiving the first message frame, the station can make a random selection of resource units based on the random number selected within the range specified by the AP and the first information and / or the second information in the first message frame according to the UORA mechanism. The UORA mechanism is not described in detail in embodiments of the present disclosure to avoid unnecessarily obscuring the inventive concept of the present disclosure.

[0084] Figure 3 is a flowchart illustrating another communication method according to an example embodiment. Figure 3 The illustrated communication method can be applied to a station.

[0085] Referring to Figure 3 In step 310, the station can receive a first message frame. The first message frame can include at least one of first information and second information, where the first information is information indicating a single-type resource unit for random access, and the second information is information indicating a composite resource unit for random access. The first information and the second information can be similar to Figure 2 The description of step 210 of FIG. 2 and Tables 2 to 5 is omitted here for the sake of brevity.

[0086] In step 320, the access point can perform a random selection of resource units according to the first message frame. For example, the station can make a random selection of resource units based on the random number selected within the range specified by the AP and the first information and / or the second information in the first message frame according to the UORA mechanism. The UORA mechanism is not described in detail in embodiments of the present disclosure to avoid unnecessarily obscuring the inventive concept of the present disclosure.

[0087] According to an embodiment, in response to the station being associated with the access point, a composite resource unit is selected from a plurality of composite resource units for random access based on the first identifier in the first information.

[0088] According to an embodiment, in response to the station not being associated with the access point, a composite resource unit is selected from one or more composite resource units for random access based on the first identifier in the first information.

[0089] Figure 2 and Figure 3 The communication method according to embodiments of the present disclosure illustrated above redefines (extends) the message frame for allocating uplink transmission resources, which can be applied to a communication environment in which IEEE 802.11be stations coexist with IEEE 802.11ax stations, to allocate transmission resources to stations that have data buffered but have not obtained uplink resources, to make a random selection, thereby improving frequency utilization efficiency and increasing system throughput.

[0091] Referring to Figure 4 , the communication device 400 can include a processing module 410 and a communication module 420.

[0092] The processing module 410 can be configured to determine a first message frame. According to an embodiment, the first message frame can include at least one of first information and second information, wherein the first information is information indicating a single-type resource unit for random access, and the second information is information indicating a composite resource unit for random access. The first information and the second information in the first message frame can be similar to the description with reference to Figure 2 and Tables 2 to 5, and repeated description is omitted here for brevity. The communication module 420 can be configured to transmit the first message frame.
