DETAILED DESCRIPTION

[0046] The following describes in more detail the embodiments of the present invention, illustrated by means of the accompanying drawings. The following description is given with reference to the accompanying drawings, in which like numbers designate the same or like elements, unless expressly indicated otherwise. The exemplary embodiments set forth in the following description do not cover all embodiments that do not conflict with the disclosure of the present invention. On the contrary, this description provides only examples of the implementation of devices and methods corresponding to aspects related to the disclosure of the invention, the essence of which is set forth in the attached claims.

[0047] The communication resource allocation method proposed by the disclosure of the present invention is applicable to a Wireless Local Area Network (WLAN) communication system comprising at least one STA and an AP. The STA transmits the information and initiates the association process with the AP through the link resource assigned by the AP.

[0048] STA, according to the disclosure of the present invention, can be considered as a user terminal in a WLAN. The user terminal may be called a user equipment (UE, User Equipment), a mobile station (MS, Mobile Station), a mobile terminal, and the like. The user terminal may be a device that provides a user with voice and/or data communication capabilities. For example, the terminal may be a portable device, a vehicle-mounted device, or the like that supports a wireless communication function. Examples of terminals currently in use include: smartphones (mobile phones), personal digital assistants (PPCs, Pocket Personal Computers), laptop computers, personal information devices (PDAs, Personal Digital Assistants), laptops, tablets, wearable devices, clients "Internet of Things" (IoT, Internet of Things), devices built into vehicles, etc. According to the disclosure of the present invention, an AP is an equipment, a router, or the like, through which a WLAN user terminal accesses a network.

[0049] In the current state of the art, the IEEE 802.11 standard is used to assign resources to STAs. For example, according to IEEE 802.11ax, a Media Access Control (MAC) mechanism is used to assign RUs to STAs in a certain frequency band. In FIG. 1 is a block diagram illustrating the maximum number of RUs assigned to different RU types (26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, 996-tone RU, 2*996 tone RU) in each frequency band (20 MHz, 40 MHz, 80 MHz, 80+80/160 MHz) according to IEEE 802.11ax. However, in resource assignment, one RU is assigned to each STA in a particular frequency band at a particular point in time. Only one RU is assigned to each STA, and there are many unused resources, whereby resources are wasted and the resource utilization efficiency is low.

[0050] For example, in FIG. 2 shows that there are only two users in the 80 MHz band. If a 242-tone RU marked with a shaded area is assigned to one user, a maximum of 484-tone RU marked with a shaded area can be assigned to another user, while the 242-tone RU and 26-tone RU marked in white are not used. This results in a reduction in spectrum usage by more than a quarter.

[0051] At present, IEEE802.11 has established the IEEE802.11be study group to study the core technology of next generation Wi-Fi (802.11a/b/g/n/ac/ax). The scope of the study includes the following aspects: 320 MHz transmission bandwidth, aggregation and coordination of multiple frequency bands, and the like. The proposed study is designed to improve speed and throughput at least four times over the current 802.11ax standard. These scenarios consider video transmission, augmented reality (AR, Augmented Reality), virtual reality (VR, Virtual Reality), etc.

[0052] Multi-band aggregation and coordination refers to simultaneous communication between devices in the 2.4 GHz, 5.8 GHz, and 6-7 GHz frequency bands. For simultaneous communication between devices in multiple frequency bands, a new MAC communication resource assignment mechanism needs to be defined for management.

[0053] In view of this factor, within the framework of the disclosure of the present invention, a method for assigning communication resources is provided. According to this method, for assigning communication resources, a plurality of (at least one) RUs are assigned to each STA in order to assign sufficient resources to the STA and improve resource utilization.

[0054] FIG. 3 shows a flowchart of a method for assigning communication resources in accordance with an embodiment of the present invention. As shown in FIG. 3, the communication resource allocation method includes the following steps.

[0055] In step S31, a communication resource assignment message frame in a given channel band is generated.

[0056] According to the disclosure of the present invention, a communication resource assignment message frame may be generated based on a channel bandwidth. For example, a corresponding communication resource assignment message frame is generated for a channel bandwidth such as 20 MHz, 40 MHz, 80 MHz, 80+80/160 MHz, or 160+160/320 MHz. The communication resource assignment information bit is set in the frame of the communication resource assignment message, and at least one RU assigned to the STA is identified by the communication resource assignment information bit.

[0057] In step S32, a communication resource assignment message frame is transmitted.

[0058] According to the disclosure of the present invention, by generating a communication resource assignment message frame to identify at least one RU assigned to a STA in a given channel band, and transmitting a communication resource assignment message frame, multiple (at least one ) RU for STA. Sufficient communication resources are assigned to STAs to improve spectrum efficiency.

[0059] In the following, the disclosure of the present invention will describe a communication resource assignment message frame and a process for using a communication resource assignment message frame to assign communication resources to an STA in conjunction with applications.

[0060] According to an implementation method, within the scope of the disclosure of the present invention, the type of RUs and the number of RUs assigned to the STA are identified by the communication resource assignment information bit set in the frame of the communication resource assignment message so as to identify the assigned RUs.

[0061] According to the disclosure of the present invention, the type of RU and the number of RUs may be encoded separately to determine different types of RUs and the number of RUs through coded values.

[0062] For example, according to the disclosure, the first bit is set to indicate the type of RU and the second bit is set to indicate the number of RUs, respectively.

[0063] For example, the number of bits of the first bit is determined based on the total number of RU types, and different bit values of the first bit are configured to indicate different RU types. For example, if the channel bandwidth is 320 MHz, the RU types include the following 8 types: 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, 996-tone RU, 1992-tone RU and 3984-tone RU. Thus, different types of RUs can be identified by different bit values consisting of at least 3 bits. For example, "000" identifies "26-tone RU", "001" identifies "52-tone RU", "010" identifies "106-tone RU", "011" identifies "242-tone RU", "100" identifies "448-tone RU", "101" identifies "996-tone RU", "110" identifies "1992-tone RU", and "111" identifies "3984-tone RU".

[0064] According to the disclosure of the present invention, the situation associated with the assignment of RUs in each channel band, and the total number of RUs that can be assigned for each type of RU (that is, the sum of the maximum number of RUs that can be assigned in different channel bands ) may be determined based on the maximum number of RUs that can be assigned in each channel band (see FIG. 1).

[0065] For example, if the channel bandwidth is 20 MHz, then the RU assignment situation is as follows: 9*26 tone resource, 4*52 tone resource, 2*106 tone resource, and 1*242 tone resource , and if the channel bandwidth is 160 MHz, then the RU assignment situation is as follows: 76*26 tone resource, 32*52 tone resource, 16*106 tone resource, 8*242 tone resource, 4* 448 tone resource, 2*996 tone resource and 1*2*996 tone resource. Because IEEE802.11be supports 320MHz bandwidth, the RU classification should be double that of 160MHz, namely: 76*2*26-tone resource, 32*2*52-tone resource, 16*2*106 -tone resource, 8*2*242-tone resource, 4*2*448-tone resource, 2*2*996-tone resource, 2*2*996-tone resource and 1*2*1992-tone resource.

[0066] For example, if the 20 MHz band is taken as a reference point, then 40 MHz, 80 MHz, 80+80/160 MHz, and 160+160/320 MHz resources can be represented, and the total number of RUs that can be allocated to of each type of RU is:

[0067] Поскольку общее количество RU, которое можно назначить для каждого типа RU, является фиксированным, количество RU, которое можно назначить для каждого типа RU, согласно раскрытию настоящего изобретения, может нумероваться в порядке 20 МГц, 40 МГц, 80 МГц, 80+80/160 МГц и 160+160/320 МГц. Порядковые номера могут представлять полосу частот канала и соответствующее количество назначаемых RU. Например, общее количество RU, которое может выделяться для 26-тонового RU, составляет: 9+18+37+74+148=286. Количество RU, которое может выделяться для каждого типа RU, нумеруется на основе следующего порядка: 20 МГц, 40 МГц, 80 МГц, 80+80/160 МГц и 160+160/320 МГц в виде 1, 2, 3, 4… 286. Конкретные значения порядковых номеров 1-9 представляют количество назначаемых RU и представляют полосу частот канала 20 МГц. Конкретные значения порядковых номеров 10-27 представляют количество назначаемых RU и представляют полосу частот канала 40 МГц. Таким же образом другие порядковые номера представляют соответствующую полосу частот канала и соответствующее количество назначаемых RU. Следует принимать во внимание, что нумерация количества RU, согласно раскрытию настоящего изобретения, также представляет кодирование позиций RU. Например, после числового кодирования 26-тонового RU существуют 9 RU в полосе частот канала, составляющей 20 МГц. Цифровая нумерация осуществляется слева направо в диапазоне 1-9, и для номеров позиций также используются цифры 1-9. В полосе частот канала, составляющей 40 МГц, 18 RU нумеруются в виде 10-27 слева направо, и номера позиций также нумеруются в виде 10-27.

[0067] Since the total number of RUs that can be assigned to each RU type is fixed, the number of RUs that can be assigned to each RU type according to the disclosure of the present invention can be numbered in the order of 20 MHz, 40 MHz, 80 MHz, 80+ 80/160 MHz and 160+160/320 MHz. The sequence numbers may represent the channel bandwidth and the corresponding number of assigned RUs. For example, the total number of RUs that can be allocated for a 26-tone RU is: 9+18+37+74+148=286. The number of RUs that can be allocated for each RU type is numbered based on the following order: 20 MHz, 40 MHz, 80 MHz, 80+80/160 MHz and 160+160/320 MHz as 1, 2, 3, 4… 286 The specific sequence number values 1-9 represent the number of assigned RUs and represent the 20 MHz channel bandwidth. Specific sequence number values 10-27 represent the number of assigned RUs and represent a 40 MHz channel bandwidth. In the same way, the other sequence numbers represent the corresponding channel bandwidth and the corresponding number of assigned RUs. It should be appreciated that the numbering of the number of RUs, according to the disclosure of the present invention, also represents the encoding of the positions of the RUs. For example, after numerically encoding a 26-tone RU, there are 9 RUs in a 20 MHz channel bandwidth. Numerical numbering is from left to right in the range 1-9, and the numbers 1-9 are also used for position numbers. In the channel bandwidth of 40 MHz, the 18 RUs are numbered as 10-27 from left to right, and the position numbers are also numbered as 10-27.

[0068] For example, according to the disclosure of the present invention, the number of bits of the second bit is determined based on the type of RU and the maximum number of RUs to be allocated in each channel band. In other words, the number of bits for indicating the number of RUs may represent the sum of the maximum number of assigned RUs for the RU type in each channel band. According to the disclosure of the present invention, the RU type is indicated by the number of second bits, and the channel bandwidth as well as the number of resource blocks assigned in the channel bandwidth for the RU type indicated by the number of second bits may be indicated by the bit value of the second bit. For example, if the RU type is 26-tone RU, the total number of RUs that can be allocated is: 9+18+37+74+148=286 based on the maximum number of RUs that can be allocated in each channel band, as shown in fig. 1, so at least 9 bits are used to indicate that the RU type is: 26-tone RU. The different bit values of the 9-bit number can characterize the sequence numbers after the RU numbering that can be assigned to each RU type in the order of 20 MHz, 40 MHz, 80 MHz, 80+80/160 MHz, and 160+160/320 MHz, and also represent the channel bandwidth; and the number of RUs that can be assigned to the RU type indicated by the number of second bits in the channel bandwidth.

[0069] In general, according to the disclosure of the present invention, the first bit and the second bit can be used to generate a communication resource assignment information bit, as well as to identify the type of RU and the number of RUs assigned to the STA. The number of communication resource assignment information bits is at least:

26-tone RU: 12 bits

52-tone RU: 11 bits

106-tone RU: 9 bits

242-tone RU: 8 bits

448-tone RU: 7 bits

996-tone RU: 6 bits

1992-tone RU: N/A

3984-tone RU: N/A

[0070] Taking a 26-tone RU as an example, for a 20 MHz channel bandwidth, at least 12 bits may be used for a communication resource assignment information bit to identify the RU type and RU position for multiple resource assignment. The first three bits identify the type of RU, and the last 9 bits identify the number of RUs.

[0071] For example, according to the disclosure of the present invention, in order to indicate the STA for which RUs are allocated, the STA identifier can be set in the communication resource assignment message frame. The STA ID is one-to-one with the RU. The STA identifier may be configured to clearly indicate the STA to which the RUs are allocated and the RUs assigned to the STA.

[0072] In addition, according to the disclosure of the present invention, obtaining the above communication resource assignment information message frame can be performed by modifying the trigger frame format (TF-R, Trigger Frame) in IEEE802.11ax. For example, according to the disclosure of the present invention, obtaining a communication resource assignment information bit may be performed by adding bit(s) to the "RU assignment" field in the TF-R shown in FIG. 4. Further, the STA ID in the communication resource assignment information message frame may be represented by an Association Identifier (AID) field in the TF-R shown in FIG. 4. In addition, according to the disclosure of the present invention, the UL BW (uplink channel bandwidth) in the TF-R shown in FIG. 5 may be padded with bit(s) for specifying the channel bandwidth specified by the communication resource assignment information message frame.

[0073] According to the disclosure of the present invention, in order to identify that the TF-R after the format change is a communication resource assignment information message frame including a communication resource assignment information bit, the assignment identification bit of a plurality of resource blocks may be set. The multiple resource block assignment identification bit indicates that the communication resource assignment information message frame contains a communication resource assignment information bit for identifying at least one resource block assigned to the STA. The assignment identification bit of the plurality of resource blocks may be set in the position of the reserved bit TF-R. For example, the reserved bit "1" indicates that TF-R is a communication resource assignment information message frame containing a communication resource assignment information bit.

[0074] The following describes an example of assigning multiple RUs to one STA in a 20 MHz channel band. In the communication resource assignment message frame generated when assigning a plurality of RUs to the STA in the 20 MHz channel band, in the UL BW field shown in FIG. 5, a 20 MHz band can be set, 1 is set in the reserved position shown in FIG. 5 to identify a destination for an STA of a plurality of RUs, and the type of RU and the number of RUs for the multiple assignment are identified using 12 bits in the "RU Destination" field shown in FIG. 4, where the first three bits identify the type of RU and the last 9 bits identify the number of RUs.

[0075] In addition, according to the disclosure of the present invention, if a plurality of RUs are assigned to a STA, then the number of RUs to be assigned may be determined based on the given channel bandwidth and the number of tones contained in the RUs. For example, the number of assigned RUs is inversely proportional to the size of a given channel bandwidth and directly proportional to the number of tones (subcarriers) contained in an RU. The specified channel bandwidth can be 20 MHz, 40 MHz, 80 MHz, 80+80/160 MHz, or 160+160/320 MHz. In addition, according to the disclosure of the present invention, if a plurality of RUs are assigned to a STA, then a plurality of RUs are allocated to the STAs in descending order according to the number of tones indicated by the type of RU, in order to ensure a minimum interval between the plurality of assigned RUs and improve spectrum efficiency.

[0076] For example, RUs for different channel bands may be allocated as shown in Table 1 below.

[0077] According to an example, the assignment can be performed in descending order according to the number of tones indicated by the RU type by using a given baseband as the minimum assignment block. This sets the bandwidth to 20 MHz. Of course, other frequency bands can be used.

[0078] Table 2 below shows an example of using a 40 MHz bandwidth with a 20 MHz reference bandwidth.

[0079] Table 3 below shows an example of using the 80 MHz band with the 40 MHz band as the reference band.

[0080] Table 4 below shows an example of using a 160 MHz band with an 80 MHz band as a reference band.

[0081] According to the disclosure of the present invention, if a given baseband is used as the minimum allocation unit, and the assignment can be performed in descending order according to the number of tones indicated by the RU type, then the maximum number of RUs that can be assigned in given reference frequency band.

[0082] For example, in FIG. 2 shows that there are two AP-associated STAs in the 40 MHz channel band, namely STA1 and STA2. The specified reference bandwidth is 20 MHz. When using the communication resource allocation method according to the disclosure of the present invention, if the resource required by STA1 is a 242-tone RU, then the leftmost 242-tone RU for STA1 is assigned first. Then, assignment of the remaining resources (with the largest combination of RUs) to STA2 is performed according to the communication resource required by STA2. For example, according to an embodiment of the disclosure of the present invention, a maximum of the remaining 242-tone RUs, 26-tone RUs, and 484-tone RUs can be allocated to STA2 to avoid wasting spectrum resources and improve spectrum efficiency.

[0083] According to an embodiment of the present invention, by generating a communication resource assignment message frame for identifying at least one RU assigned to an STA in a given channel band, and transmitting a communication resource assignment message frame for STA assignment, a plurality of RUs can be assigned a sufficient amount of communication resources, as a result of which the spectrum utilization factor may increase.

[0084] Based on the same concept, within the scope of the disclosures of the present invention, an apparatus for assigning communication resources is provided.

[0085] It is to be appreciated that in order to implement the above functions, the communication resource assigner is equipped with hardware structures and/or software modules to perform each respective function. In conjunction with the blocks and operations of the examples described in the embodiments of the disclosure of the present invention presented in this specification, the disclosure of the present invention may be implemented in hardware or a combination of hardware and computer software. Whether a particular function is implemented in hardware or through a combination of hardware and software depends on the particular application and design constraints of the technical solutions.
