Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a resource allocation method, a communication device, and related devices.

Background Art

[0002] In a conventional Wireless Local Area Network (WLAN), when each station needs to transmit uplink data, the station occupies the entire channel for data transmission in a contention manner. As a result, the frequency utilization efficiency is greatly reduced. To improve this situation, currently, the OFDMA technology is used to divide the wireless channel into a plurality of sub-channels (sub-carriers) in the frequency domain to form a resource unit (RU). Since user data is carried by a part of the resource unit instead of occupying the entire channel, multiple users can perform parallel transmissions simultaneously in each time period without waiting in turn or competing with each other. This improves the frequency utilization efficiency.

[0003] In the downlink, the access point (AP) can determine the status of allocating RUs based on the priority of the downlink data of each station. However, in the uplink, the AP needs to notify the terminal device of the allocated resource unit by using a trigger frame. The trigger frame includes a plurality of user information fields, and one user information field includes the information that one station needs to read. For example, M user information fields are the information that stations 1 to M need to read respectively. The resource unit allocation sub-field in the user information field indicates the resource unit allocated to the station. Further, the station can transmit a data packet on the allocated resource unit.

[0004] However, the size of the data that needs to be transmitted in the uplink varies depending on the station, and how to allocate a plurality of resource units to one station is an urgent problem to be solved.

Summary of the Invention

Means for Solving the Problems

[0005] The present application provides a resource allocation method, a communication device, and related devices for allocating a plurality of resource units to each station.

[0006] According to a first aspect, the present application provides a resource allocation method. In this method, a station receives a trigger frame from an access point. The trigger frame includes a plurality of user information fields that are the same as the association identifier of the station, and each user information field indicates one or more resource units allocated to the station. Therefore, the station can determine one or more resource units indicated by each of the plurality of user information fields as a plurality of allocated resource units.

[0007] In another possible design, to allocate a plurality of resource units to a station, the trigger frame includes one user information field that is the same as the association identifier of the station, and the user information field indicates a plurality of resource units allocated to the station. In this design, a plurality of resource units are allocated to the station by using one user information field so that the amount of user information fields required is reduced. This helps to allocate a plurality of resource units to a plurality of stations simultaneously.

[0008] In one possible implementation, for the local unit to determine a plurality of allocated resource units based on a trigger frame includes the local unit selecting, from the trigger frame, one or more user information fields that are the same as the association identifier of the local unit. For each of the selected one or more user information fields, the local unit determines one or more resource units indicated by the user information field. The one or more resource units indicated by each of the selected one or more user information fields are the plurality of resource units allocated to the local unit.

[0009] The user information fields in the trigger frame can be expanded in the user information list field. Thus, this implementation can alternatively be to select one or more user information fields that are the same as the association identifier of the local unit from the user information list field.

[0010] For the specific manner in which the local unit selects one or more user information fields from the user information list field, refer to the following four alternative possible implementations. Alternatively, the four possible implementations can be used in combination. This is not limited in this application.

[0011] In one possible implementation, the local unit separately analyzes the association identifier indicated by the association identifier field in each of all the user information fields in the trigger frame, and selects one or more user information areas that are the same as the association identifier of the local unit from all the analyzed user information fields. All the user information fields can be expanded in the user information list field. The local unit can analyze all the user information fields based on the boundary of the user information list field. Since the user information list field does not need to be modified in this way, it can be seen that the resource allocation method has higher compatibility.

[0012] In other possible implementations, the access point may configure N for the station in a predefined protocol manner or by using signaling, where N is the amount of user information fields included in the trigger frame that is the same as the station's association identifier. Alternatively, the access point may configure the amount of resource units N1 that can be allocated to the station and the amount of resource units N2 that can be indicated by each user information field in a predefined protocol manner or by using signaling. In this case, the amount of user information fields N included in the trigger frame that is the same as the station's association identifier may be equal to N1 / N2.

[0013] In this implementation, for the station to select one or more user information fields from the trigger frame that are the same as the station's association identifier, the station needs to analyze whether the association identifier indicated by the association identifier field in each user information field is the same as the station's association identifier based on the index of each user information field in the trigger frame, and stop analyzing whether the association identifier indicated by the association identifier field in each user information field is the same as the station's association identifier until the amount of user information fields that are the same as the station's association identifier equals N, and then select N user information fields that are the same as the station's association identifier from all the analyzed user information fields.

[0014] It can be seen that in this implementation, the amount of user information fields analyzed by the station can be reduced. This helps to reduce the processing load of the station.

[0015] In yet another possible implementation, the user information field may include an end flag. The end flag can be set by reusing other information fields, or by using reserved fields, or by using newly added bits in the user information field. The end flag indicates whether the allocation of resource units to the station has ended. In this implementation, it can be seen that the amount of user information field analyzed by the station can be further reduced. This helps to reduce the processing load of the station.

[0016] For the station to select one or more user information fields that are the same as the station's association identifier from the trigger frame, the station analyzes whether the association identifier indicated by the association identifier field in each user information field is the same as the station's association identifier based on the index of each user information field in the trigger frame, and stops performing the step of analyzing whether the association identifier indicated by the association identifier field in each user information field is the same as the station's association identifier until the end flag in the analyzed user information field indicates that the allocation of resource units to the station has ended, and includes selecting one or more user information fields that are the same as the station's association identifier from all the analyzed user information fields.

[0017] In yet another possible implementation, for the local station to select one or more user information fields that are the same as the local station's association identifier from the trigger frame means that, based on the index of each user information field, starting from the first user information field in the trigger frame that is the same as the local station's association identifier, the local station analyzes whether the association identifier indicated by the association identifier field in each user information field is the same as the local station's association identifier until a user information field different from the local station's association identifier is analyzed, and then selects one or more user information fields that are the same as the local station's association identifier from all the analyzed user information fields. In this implementation, since the multiple user information fields corresponding to each local station can be continuously allocated in the user information list field of the trigger frame, the complexity of the local station's analysis can be greatly reduced.

[0018] The following describes how a user information field indicates one or more resource units and how a local station determines one or more resource units indicated by each user information field by using some optional implementations.

[0019] In a possible implementation, the user information field includes a resource unit indication. For the local station to determine the multiple resource units indicated by the user information field includes the local station determining the multiple resource units indicated by the resource unit indication in the user information field. In this implementation, it can be seen that the resource unit indication can indicate multiple resource units.

[0020] Optionally, the multiple resource units indicated by the resource unit indication are a combination of two first resource units, where the first resource unit is a resource unit including 996 subcarriers, a combination of four first resource units, The combination of two first resource units with the lowest frequencies and one first resource unit with the highest frequency within the 320 MHz frequency band range, The combination of one first resource unit with the lowest frequency and two first resource units with the highest frequency within the 320 MHz frequency band range, The combination of three first resource units with the lowest frequency within the 320 MHz frequency band range, The combination of three first resource units with the highest frequency within the 320 MHz frequency band range, The combination of two first resource units, where the first resource unit is a resource unit containing 996 sub - carriers, and The combination of four first resource units A plurality of resource units corresponding to any one of the above combinations.

[0021] In other possible implementations, the user information field includes a frequency band range indication and a resource unit indication. The frequency band range indication indicates an 80 MHz frequency band range within the bandwidth, and the resource unit indication indicates one resource unit. For the station to determine one resource unit indicated by the user information field means that the station determines one resource unit indicated by the resource unit indication based on the frequency band range indicated by the frequency band range indication. Since each of the plurality of user information fields selected by the station indicates one resource unit, it can be seen that a plurality of resource units assigned to the station can be obtained.

[0022] In this implementation, regardless of the bandwidth range of the combination of resource units and the amount of RUs required, it can be seen that the amount of user information fields can each indicate the same amount of RUs.

[0023] Optionally, one resource unit indicated by the resource unit indication is Any seventh resource unit, where the seventh resource unit is a resource unit containing 2 x 996 sub - carriers, the seventh resource unit, Any sixth resource unit within the frequency band range indicated by the frequency band range indication, where the sixth resource unit is a resource unit containing 52 sub - carriers, the sixth resource unit, Any fifth resource unit within the frequency band range indicated by the frequency band range indication, where the fifth resource unit is a resource unit containing 26 sub - carriers, the fifth resource unit, Any fourth resource unit within the frequency band range indicated by the frequency band range indication, where the fourth resource unit is a resource unit containing 106 sub - carriers, the fourth resource unit, Any third resource unit within the frequency band range indicated by the frequency band range indication, where the third resource unit is a resource unit containing 242 sub - carriers, the third resource unit, Any second resource unit within the frequency band range indicated by the frequency band range indication, where the second resource unit is a resource unit containing 484 sub - carriers, the second resource unit, and Any first resource unit within the frequency band range indicated by the frequency band range indication, where the first resource unit is a resource unit containing 996 sub - carriers, the first resource unit is any one of the resource units described above.

[0024] In yet another implementation form, the resource unit indication indicates a plurality of resource units. In other words, the station determines a plurality of resource units indicated by the resource unit indication based on the frequency band range indicated by the frequency band range indication. The station may be notified of the association between the index or value of the resource unit indication and the combination of the plurality of resource units in a manner predefined by the protocol or in a signaling configuration manner.

[0025] In this implementation form, it can be seen that one user information field may indicate a plurality of resource units regardless of the bandwidth range of the combination of resource units.

[0026] Optionally, a method in which one user information field is required to indicate every 80 MHz is used. In this case, up to two user information fields are required to indicate the combination of RUs in a frequency band range higher than 80 MHz and up to 160 MHz. Up to four user information fields are required to indicate the combination of RUs in a frequency band range higher than 160 MHz and up to 320 MHz. Alternatively, a method in which one user information field is required to indicate every 160 MHz is used. In this case, up to one user information field is required to indicate the combination of RUs in a frequency band range up to 160 MHz. Up to two user information fields are required to indicate the combination of RUs in a frequency band range higher than 160 MHz and up to 320 MHz.

[0027] In addition, when three 996-tone RUs are combined, each 996-tone RU is indicated by using one user information field, and three user information fields may be required to indicate the combination of the three 996-tone RUs. When four RUs in a 160 MHz frequency band range, for example, 484-tone RU, 242-tone RU, 484-tone RU, and 242-tone RU are combined, one user information field is required to indicate the combination of one 484-tone RU and one 242-tone RU every 80 MHz. In this case, two user information fields may indicate the combination of the four RUs.

[0028] Optionally, a plurality of resource units indicated by a resource unit indication are a combination of a fourth resource unit at the lowest frequency in one 20 MHz frequency band range indicated by a frequency band range indication and a fifth resource unit at the center of the 20 MHz frequency band range, a combination of a fourth resource unit at the highest frequency in one 20 MHz frequency band range and a fifth resource unit at the center of the 20 MHz frequency band range, a combination of a sixth resource unit at the second lowest frequency in one 20 MHz frequency band range and a fifth resource unit in the 20 MHz frequency band range that is on the same side as and adjacent to the sixth resource unit, a combination of a sixth resource unit at the second lowest frequency in one 20 MHz frequency band range and a fifth resource unit at the center of the 20 MHz frequency band range, a combination of a sixth resource unit at the second highest frequency in one 20 MHz frequency band range and a fifth resource unit in the 20 MHz frequency band range that is on the same side as and adjacent to the sixth resource unit, The combination of the sixth resource unit at the second highest frequency within a 20 MHz frequency band range and the fifth resource unit at the center of the 20 MHz frequency band range, The combination of the second resource unit within the frequency band range and the third resource unit adjacent to the second resource unit, The combination of the second resource unit within the frequency band range and the third resource unit not adjacent to the second resource unit, The combination of two third resource units on both sides of the frequency band range, The combination of the first resource unit corresponding to the frequency band range and the second resource unit that is within 80 MHz of a lower frequency adjacent to the first resource unit and not adjacent to the first resource unit, The combination of the first resource unit corresponding to the frequency band range and the second resource unit that is within 80 MHz of a higher frequency adjacent to the first resource unit and not adjacent to the first resource unit, The combination of the first resource unit corresponding to the frequency band range and the third resource unit that is within 80 MHz of a lower frequency adjacent to the first resource unit and adjacent to the first resource unit, The combination of the first resource unit corresponding to the frequency band range and the third resource unit that is within 80 MHz of a higher frequency adjacent to the first resource unit and adjacent to the first resource unit, The combination of the first resource unit corresponding to the frequency band range and two third resource units that are within 80 MHz of a lower frequency adjacent to the first resource unit, The combination of the first resource unit corresponding to the frequency band range and two third resource units that are within 80 MHz of a higher frequency adjacent to the first resource unit, One second resource unit and one third resource unit within the frequency band range, and one second resource unit and one third resource unit within a lower frequency band range adjacent to the frequency band range One second resource unit and one third resource unit within the frequency band range, and one second resource unit and one third resource unit within a higher frequency band range adjacent to the frequency band range A plurality of resource units corresponding to any one of the combinations

[0029] The sixth resource unit is a resource unit including 52 sub - carriers, the fifth resource unit is a resource unit including 26 sub - carriers, the fourth resource unit is a resource unit including 106 sub - carriers, the third resource unit is a resource unit including 242 sub - carriers, the second resource unit is a resource unit including 484 sub - carriers, and the first resource unit is a resource unit including 996 sub - carriers

[0030] In this implementation form, it can be seen that one user information field can be used for indication regardless of the range of the bandwidth of the RU combination

[0031] In yet another possible implementation, the user information field includes a frequency band range indication, a resource unit indication, and a resource unit combination indication. The frequency band range indication indicates a frequency band range of 80 MHz within the bandwidth, the resource unit indication indicates one resource unit within the frequency band range, and the resource unit combination indication indicates a combination of a plurality of resource units. The combination of a plurality of resource units includes the resource unit indicated by the resource unit indication. In this implementation, it can be seen that the resource unit allocation subfield within the user information field can be modified so that the user information field can indicate a combination of a plurality of resource units. In this implementation, it can be seen that one user information field can be used for indication regardless of the bandwidth range of the combination of RUs.

[0032] Optionally, a method is used in which one user information field is required to indicate every 80 MHz. In this case, a maximum of one user information field is required to indicate the combination of RUs in a frequency band range that is 80 MHz or less. A maximum of two user information fields are required to indicate the combination of RUs in a frequency band range that is higher than 80 MHz and 160 MHz or less. A maximum of four user information fields are required to indicate the combination of RUs in a frequency band range that is higher than 160 MHz and 320 MHz or less.

[0033] Alternatively, a method is used in which one user information field is required to indicate every 160 MHz. In this case, a maximum of one user information field is required to indicate the combination of RUs in a frequency band range that is 160 MHz or less. A maximum of two user information fields are required to indicate the combination of RUs in a frequency band range that is higher than 160 MHz and 320 MHz or less.

[0034] In addition, three 996-tone RUs can be combined, and each 996-tone RU is indicated by using one user information field, and three user information fields may be required to indicate the combination of the three 996-tone RUs. In this case, an implementation form in which the user information field indicates one resource unit can be used.

[0035] When four RUs within a 160 MHz frequency band range, for example, 484-tone RUs, 242-tone RUs, 484-tone RUs, and 242-tone RUs are combined, in order to indicate the combination of one 484-tone RU and one 242-tone RU, one user information field is required to indicate every 80 MHz. In this case, a method in which one user information field indicates a plurality of resource units may be used, that is, two user information fields are required to indicate the combination of the four RUs. Optionally, a method in which one user information field is required to indicate every 160 MHz is used. In this case, one user information field is required to indicate the combination of the four RUs.

[0036] Correspondingly, for the station to determine a plurality of resource units indicated by the user information field, the station determines the combination of the plurality of resource units as the plurality of resource units indicated by the user information field based on the resource unit combination indication and the resource units indicated by the resource unit indication.

[0037] Optionally, the association between the index or value of the resource unit combination indication and the combination of the plurality of resource units can be determined in a manner predefined by the protocol or in a signaling configuration manner. The following describes possible associations.

[0038] In an optional implementation, the resource unit combination indication indicates a combination of a fourth resource unit and a fifth resource unit. The fourth resource unit is a resource unit including 106 sub - carriers indicated by the resource unit indication, and the fifth resource unit is a resource unit including 26 sub - carriers located in the center of the 20 MHz frequency band range where the fourth resource unit is located.

[0039] In an optional implementation, the resource unit combination indication indicates a combination of a sixth resource unit and a fifth resource unit. The sixth resource unit is a resource unit including 52 sub - carriers indicated by the resource unit indication, and the fifth resource unit is a resource unit including 26 sub - carriers located in the center of the 20 MHz frequency band range where the sixth resource unit is located, or a resource unit including 26 sub - carriers on the same side as and adjacent to the sixth resource unit.

[0040] In an optional implementation, the resource unit combination indication indicates a combination of a second resource unit and a third resource unit. The second resource unit is a resource unit including 484 sub - carriers indicated by the resource unit indication, and the third resource unit is a resource unit including 242 sub - carriers adjacent to the second resource unit in the frequency band range, or a resource unit including 242 sub - carriers not adjacent to the second resource unit in the frequency band range.

[0041] In an optional implementation, the resource unit combination indication indicates a combination of two third resource units, and the two third resource units are two resource units each including 242 sub - carriers at the outermost side of the frequency band range.

[0042] In an optional implementation form, the first resource unit is a resource unit including 996 sub-carriers indicated by a resource unit instruction. The resource unit combination instruction indicates any one of the following combinations of a plurality of resource units: a combination of the first resource unit and the second resource unit, where the second resource unit is a resource unit including 484 sub-carriers that is not adjacent to the first resource unit; a combination of the first resource unit and the third resource unit, where the third resource unit is a resource unit including 484 sub-carriers that is not adjacent to the first resource unit and a resource unit including 242 sub-carriers; and a combination of two third resource units each including 242 sub-carriers at the outermost side of the frequency band range, where the two third resource units are two resource units.

[0043] In an optional implementation form, the first resource unit is a resource unit including 996 sub-carriers indicated by a resource unit instruction. The resource unit combination instruction is a combination of the second resource unit and the first resource unit, where the second resource unit is a resource unit including 484 sub-carriers that is not adjacent to the first resource unit and is within 80 MHz of a lower frequency adjacent to the first resource unit; a combination of the second resource unit and the first resource unit, where the second resource unit is a resource unit including 484 sub-carriers that is not adjacent to the first resource unit and is within 80 MHz of a higher frequency adjacent to the first resource unit; A combination of a second resource unit, a third resource unit, and a first resource unit, wherein the second resource unit is a resource unit including 484 subcarriers within 80 MHz of a lower frequency adjacent to the first resource unit, and the third resource unit is a resource unit including 242 subcarriers within 80 MHz of a lower frequency adjacent to the first resource unit. A combination of a second resource unit, a third resource unit, and a first resource unit, wherein the second resource unit is a resource unit including 484 subcarriers within 80 MHz of a higher frequency adjacent to the first resource unit, and the third resource unit is a resource unit including 242 subcarriers within 80 MHz of a higher frequency adjacent to the first resource unit, and A combination of a first resource unit and two resource units each including 996 subcarriers and adjacent to the first resource unit represents any one of a plurality of combinations of resource units.

[0044] The frequency band range indicated by the frequency band range indication is any one of a primary 80 MHz frequency band range, a secondary 80 MHz frequency band range, a third 80 MHz frequency band range, and a fourth 80 MHz frequency band range.

[0045] In this application, the strategy of the combination of a plurality of resource units that can be indicated by the combination indication with the resource unit is not limited to the above-described possible implementation forms. The amount of bits occupied by the resource unit combination indication is related to the amount of strategies of the combination that needs to be indicated. The fact that the amount of strategies of the combination that needs to be indicated by the resource unit combination indication is smaller indicates that the required bit overhead is lower. In conclusion, the method by which the resource unit combination indication indicates the combination of a plurality of resource units can reduce the overall overhead of the method for allocating a plurality of resource units.

[0046] According to a second aspect, the present application further provides a resource allocation method. The resource allocation method is described from the perspective of an access point. In this method, the access point determines a plurality of resource units to be allocated to a station. The access point transmits a trigger frame to the station. The trigger frame includes a plurality of user information fields that are the same as the association identifier of the station, and each user information field indicates one or more resource units to be allocated to the station, or the trigger frame includes one user information field that is the same as the association identifier of the station, and the one user information field indicates a plurality of resource units to be allocated to the station.

[0047] In a possible implementation, the amount N of user information fields in the trigger frame that is the same as the association identifier of the station is configured for the station in a manner predefined by the protocol or by using signaling. Alternatively, the access point may configure the amount N1 of resource units that can be allocated to the station and the amount N2 of resource units that can be indicated by each user information field in a manner predefined by the protocol or by using signaling. In this case, the amount N of user information fields included in the trigger frame that is the same as the association identifier of the station may be equal to N1 / N2. Since the user information list field does not need to be modified in this way, it can be seen that the resource allocation method has higher compatibility.

[0048] In a possible implementation, the user information field includes an end flag, and the end flag indicates whether the allocation of resource units to the station is completed. In this implementation, it can be seen that the amount of user information fields analyzed by the station can be reduced. This helps to reduce the processing load of the station.

[0049] In one possible implementation, multiple user information fields within a trigger frame that are the same as the local association identifier are arranged consecutively. In this implementation, it can be seen that the amount of user information fields analyzed by the local unit can be further reduced. This helps to reduce the processing load of the local unit.

[0050] In one possible implementation, the user information field includes a resource unit indication, and the resource unit indication indicates a plurality of resource units assigned to the local unit. This helps to determine a plurality of assigned resource units based on the resource unit indication.

[0051] In other possible implementations, the user information field includes a frequency band range indication and a resource unit indication. The frequency band range indication indicates a frequency band range of 80 MHz in bandwidth, and the resource unit indication indicates one or more resource units assigned to the local unit. This helps to determine a plurality of assigned resource units based on the information.

[0052] In yet other possible implementations, the user information field includes a frequency band range indication, a resource unit indication, and a resource unit combination indication. The frequency band range indication indicates a frequency band range of 80 MHz in bandwidth, the resource unit indication indicates one resource unit within the frequency band range, and the resource unit combination indication indicates a combination of a plurality of resource units. The combination of the plurality of resource units includes the resource unit indicated by the resource unit indication. In this implementation, it can be seen that the resource unit allocation subfield within the user information field can be modified so that the user information field can indicate a combination of a plurality of resource units.

[0053] In a possible implementation, the frequency band range indicated by the frequency band range indication is any one of a primary 80 MHz frequency band range, a secondary 80 MHz frequency band range, a third 80 MHz frequency band range, and a fourth 80 MHz frequency band range.

Embodiments for Carrying Out the Invention

[0085] With the development of wireless local area networks, the data rate required by a station to transmit uplink data increases accordingly. Therefore, how an access point allocates a plurality of resource units to a station in order to increase the data rate so that the station can transmit uplink data by using the plurality of resource units has become an urgent problem to be solved.

[0086] To solve this problem, the present application provides a resource allocation method. In this method, an access point can allocate a plurality of resource units to a station. The plurality of resource units allocated to the station can also be referred to as a combination of a plurality of resource units or a plurality of combined resource units. Unless otherwise specified, "combination" and "combined" have the same meaning in this specification.

[0087] First, FIG. 1 is used as an example to illustrate a network structure to which the resource allocation method of the present application is applicable. FIG. 1 is a schematic diagram of a network structure according to an embodiment of the present application. As shown in FIG. 1, the network structure may include an access point (AP) and a plurality of non-access point stations (non-AP STAs). For simplicity of explanation, the non-access point station is hereinafter abbreviated as a station. FIG. 1 is described by using an example in which the network structure includes one access point (AP) and two stations (STA1 and STA2). The network structure may further include more access points and stations. Alternatively, the network structure may include only two stations. This is not limited in the present application.

[0088] An access point may be an access point used by a terminal device (such as a mobile phone) to access a wired (or wireless) network, and is mainly deployed in homes, buildings, and parks. A typical coverage radius ranges from dozens of meters to hundreds of meters. Naturally, the access point may alternatively be deployed outdoors. An access point is equivalent to a bridge that connects a wired network and a wireless network. The main function of an access point is to connect various wireless network clients together and connect the wireless network to Ethernet. Specifically, the access point can be a terminal device (such as a mobile phone) or a network device (such as a router) with a wireless fidelity (Wi-Fi) chip. The access point can be a device that supports the 802.11be standard. Alternatively, the access point can be a device that supports multiple wireless local area network (WLAN) standards of the 802.11 family, such as the 802.11be standard, 802.11ax standard, 802.11ac standard, 802.11n standard, 802.11g standard, 802.11b standard, and 802.11a standard.

[0089] The station may be a wireless communication chip, a wireless sensor, a wireless communication terminal, etc., and may also be called a user. For example, the station may be a mobile phone supporting Wi-Fi communication, a tablet computer supporting Wi-Fi communication, a set-top box supporting Wi-Fi communication, a smart television supporting Wi-Fi communication, an intelligent wearable device supporting Wi-Fi communication, an in-vehicle communication device supporting Wi-Fi communication, or a computer supporting Wi-Fi communication. Optionally, the station may support the 802.11be standard. The station may also support multiple wireless local area network (WLAN) standards of the 802.11 family, such as the 802.11be standard, 802.11ax standard, 802.11ac standard, 802.11n standard, 802.11g standard, 802.11b standard, and 802.11a standard.

[0090] For example, the access point and the station may be devices applied to the vehicle Internet, Internet of things (IoT) nodes or sensors in the Internet of things, smart cameras in a smart home, smart remote controls, and smart water meters, as well as sensors in a smart city.

[0091] To facilitate the understanding of the relevant content in the embodiments of the present application, the following describes some concepts of the embodiments of the present application.

[0092] In the embodiments of the present application, the trigger frame includes a plurality of user information fields that are the same as the associated identifier of the station, and each user information field indicates one or more resource units assigned to the station, or the trigger frame includes one user information field that is the same as the associated identifier of the station, and that one user information field indicates a plurality of resource units assigned to the station.

[0093] Optionally, the frame format of the trigger frame can be shown in FIG. 2. FIG. 2 is a schematic diagram of the structure of the trigger frame according to an embodiment of the present application. The trigger frame may include only a part of the fields shown in FIG. 2. Alternatively, the trigger frame may include more fields than those shown in FIG. 2. This is not limited in the embodiments of the present application.

[0094] For example, the trigger frame includes a common info field and a user info list field. The trigger frame may further include a frame control field, a duration field, a receiver address (RA) field, a transmitter address (TA) field, a padding field, a frame check sequence (FCS) field, etc.

[0095] The common info field may also be referred to as a common area or a common information area. The common info field includes common information that needs to be read by all stations, such as a trigger type subfield, a length subfield, a cascade indication subfield, a carrier sense required (CS Required) subfield, a bandwidth subfield, a guard interval and long training field (GI+LTF) subfield, and a trigger dependent common info subfield.

[0096] The user information list field may also be referred to as a user information list area, a per-station area, etc. The user information list field includes one or more user information fields. Each user information field includes information that needs to be read by each station, such as an Association Identifier (AID) subfield, a Resource Unit (RU) allocation subfield, a coding type subfield, a Modulation and Coding Scheme (MCS) subfield, a reserved subfield, a trigger dependent user info subfield, etc.

[0097] The association identifier field indicates the association identifier of the station corresponding to the user information field. The resource unit allocation subfield indicates the resource unit (or resource unit position) allocated to the station indicated by the user information field. In the embodiments of the present application, the user information field may indicate one or more resource units by using the resource unit allocation subfield, but this is not limited to the resource unit allocation subfield. In other words, some or all of the frequency band range indication, resource unit indication, and resource unit combination indication included in the user information field may be allocated to the resource unit allocation subfield.

[0098] The "field" described in this specification may also be referred to as an "area", "information", etc., and the "subfield" may also be referred to as a "subarea", "information", etc. The fields shown in FIG. 2 are merely examples. The trigger frame may include only a part of the fields shown in FIG. 2. Alternatively, the trigger frame may include more fields than those shown in FIG. 2.

[0099] Trigger-frame-based scheduling-based uplink transmission means that the station can transmit data packets in a plurality of allocated resource units, i.e., physical layer protocol data units (PPDUs). The data packet can be a high-efficiency trigger-based physical layer protocol data unit (HE TB PPDU) or an extremely high throughput trigger-based physical layer protocol data unit (EHT TB PPDU). The HE TB PPDU is one of the high-efficiency physical layer protocol data units (HE PPDUs). FIG. 3 is a schematic flowchart of trigger-frame-based scheduling-based uplink transmission according to an embodiment of the present application. As shown in FIG. 3, after receiving the trigger frame, the station can determine a plurality of allocated resource units and transmit a PPDU in the plurality of resource units. The structure of the PPDU is shown in FIG. 3. The case where STA1 transmits the PPDU is used as an example. From HE-LTF to Data includes a plurality of resource units for transmitting the uplink data of STA1. The functions of the fields in the PPDU are shown in Table 1 (Table 1).

[0100]

Table 1

[0101] A wireless channel is divided into a plurality of sub-channels or sub-carriers in the frequency domain. FIG. 4 is a schematic diagram of channel allocation according to an embodiment of the present application. As shown in FIG. 4, when the bandwidth is 160 MHz, the channel can be divided into a primary 20 MHz channel (also referred to as a primary channel, Primary 20 MHz, P20), a secondary 20 MHz channel (Secondary 20 MHz, S20), a secondary 40 MHz channel (Secondary 40 MHz, S40), and a secondary 80 MHz channel (Secondary 80 MHz, S80). Channel 1 may correspond to the primary 20 MHz channel, channel 2 may correspond to the secondary 20 MHz channel, channels 3 and 4 are combined into the secondary 40 MHz channel, and channels 5 to 8 are combined into the secondary 80 MHz channel.

[0102] Different amounts of subcarriers on a channel can be combined into resource units of different sizes. For bandwidths of 20 MHz, 40 MHz, 80 MHz, 160 MHz, or 320 MHz, the resource units of different sizes can include the following seven resource units: a first resource unit (which is a resource unit including 996 subcarriers and can be called a 996 - tone RU), a second resource unit (which is a resource unit including 484 subcarriers and can be called a 484 - tone Ru), a third resource unit (which is a resource unit including 242 subcarriers and can be called a 242 - tone RU), a fourth resource unit (which is a resource unit including 106 subcarriers and can be called a 106 - tone RU), a fifth resource unit (which is a resource unit including 26 subcarriers and can be called a 26 - tone RU), a sixth resource unit (which is a resource unit including 52 subcarriers and can be called a 52 - tone RU), and a seventh resource unit (which is a resource unit including 2×996 subcarriers and can be called a 2×996 - tone RU). This helps the access point to allocate multiple resource units to a station for uplink data transmission based on the data transmission requirements of each station.

[0103] FIG. 5 is a schematic diagram of possible allocations of resource units in a bandwidth of 80 MHz according to an embodiment of the present application. As shown in FIG. 5, the first row shows that the 80 MHz bandwidth may include 37 26-tone RUs, the second row shows that the 80 MHz bandwidth may include 16 52-tone RUs, the third row shows that the 80 MHz bandwidth may include 8 106-tone RUs, the fourth row shows that the 80 MHz bandwidth may include 4 242-tone RUs, the fifth row shows that the 80 MHz bandwidth may include 2 484-tone RUs, and the sixth row shows that the 80 MHz bandwidth may include 1 996-tone RU. As shown in FIG. 5, in a 20 MHz frequency band range, there may be a maximum of 9 resource units, i.e., 9 26-tone RUs.

[0104] FIG. 6 is a schematic diagram of possible allocations of resource units in a bandwidth of 160 MHz according to an embodiment of the present application. As shown in FIG. 6, the first row shows that the 160 MHz bandwidth may include 8 242-tone RUs, the second row shows that the 160 MHz bandwidth may include 4 484-tone RUs, and the third row shows that the 160 MHz bandwidth may include 2 996-tone RUs.

[0105] FIG. 7 is a schematic diagram of possible distributions of resources in a bandwidth of 320 MHz according to an embodiment of the present application. As shown in FIG. 7, the first row shows that the 320 MHz bandwidth may include 4 996-tone RUs.

[0106] The resource units shown in each row of FIGS. 5 to 7 do not occupy the entire bandwidth, and each row may include some remaining subcarriers used for separation between resource units. As shown in FIG. 5, each 20 MHz channel has a separation of two subcarriers and a separation of one subcarrier, and there is a separation of 26 subcarriers between 484-tone RUs.

[0107] The possible allocations of resource units are not limited to those shown in FIGS. 5 to 7. For example, a bandwidth of 320 MHz may include eight 484-tone RUs, etc. Alternatively, the resource unit allocation pattern shown in FIG. 4 may be used for each 80 MHz frequency band range within a 320 MHz bandwidth and for each 80 MHz frequency band range within a 160 MHz bandwidth. In other words, the possible allocations of resource units within the bandwidth are not limited in the embodiments of the present application. To facilitate the understanding of the resource allocation method in the present application, the allocations shown in FIGS. 5 to 7 are used as examples of a plurality of resource units allocated to a station to enable the station to transmit uplink data with a plurality of resource units, or the positions of a plurality of resource units allocated to the station, or which resource units are combined.

[0108] The following describes a resource allocation method and related devices in embodiments of the present application with reference to the accompanying drawings. The resource allocation method may also be referred to as a method for indicating a plurality of resource units, a method for combining a plurality of resource units, etc. In embodiments of the present application, a trigger frame is used to allocate a plurality of resource units to a station. The following provides explanations from two aspects. In the first aspect, the trigger frame indicates a plurality of resource units allocated to a station by using a plurality of user information fields. In other words, the trigger frame includes a plurality of user information (user info) fields that are the same as the association identifier of the station. In the second aspect, the trigger frame indicates a plurality of resource units allocated to a station by using one user information field. In other words, the trigger frame includes one user information (user info) field that is the same as the association identifier of the station.

[0109] 1. The trigger frame includes a plurality of user information (user info) fields that are the same as the association identifier of the station.

[0110] Each user information field may indicate one or more resource units, and the one or more resource units indicated by each of the plurality of user information fields are a plurality of resource units allocated to the local station.

[0111] FIG. 8 is a schematic flowchart of a resource allocation method according to an embodiment of the present application based on the design of a trigger frame. As shown in FIG. 8, the resource allocation method includes the following steps.

[0112] 101: Determine a plurality of resource units allocated to the local station by the access point.

[0113] 102: The access point transmits a trigger frame to the local station, and the trigger frame includes a plurality of user information fields that are the same as the association identifier of the local station. Each user information field indicates one or more resource units allocated to the local station.

[0114] 103: The local station receives the trigger frame and determines a plurality of allocated resource units based on the trigger frame.

[0115] The local station determining a plurality of allocated resource units based on the trigger frame includes the following steps.

[0116] 1031: The local station selects one or more user information fields from the trigger frame that are the same as the association identifier of the local station.

[0117] 1032: For each of the selected one or more user information fields, the local station determines one or more resource units indicated by the user information field, and the one or more resource units indicated by each of the selected one or more user information fields are a plurality of resource units allocated to the local station.

[0118] Optionally, the frame structure shown in FIG. 2 is used as an example. The user information field is allocated in the user information list field. Thus, the station may select one or more user information fields from the user information list field that are the same as the station's association identifier. In other words, the station receives the user information list field, analyzes the association identifier indicated by the association identifier field in the user information field, and selects a plurality of user information fields that are the same as the station's association identifier.

[0119] In step 1031, the station may select a plurality of user information fields from the trigger frame that are the same as the station's association identifier in some of the following optional implementations, but the following implementations are not limited thereto. For example, one or more of the following implementations may be used simultaneously to select a plurality of user information fields.

[0120] 1.1. All user information fields in the trigger frame are analyzed.

[0121] In that implementation, the station separately analyzes the association identifier indicated by the association identifier field in each of all the user information fields in the trigger frame, and may select a plurality of user information fields that are the same as the station's association identifier from all the analyzed user information fields. As shown in FIG. 2, since the user information list field in the trigger frame has a boundary, the station can analyze all user information fields based on the boundary.

[0122] For simplicity of explanation, in this specification, "a plurality of user information fields that are the same as the station's association identifier" may be referred to as the station's user information fields, user information fields that match the station, etc.

[0123] The multiple user information fields corresponding to the stations in the trigger frame may appear continuously or discontinuously. For example, assume that the user information list field includes M user information fields, the association identifier of STA1 is AID1, and the user information fields corresponding to STA1 in FIG. 9 appear continuously in the user information list field. In other words, the first two user information fields in the user information list field are the user information fields corresponding to STA1, and the third to Mth user information fields are not the user information fields corresponding to STA1. The user information fields corresponding to STA1 in FIG. 10 appear discontinuously in the user information list field. In other words, the user information fields corresponding to STA1 may be the first user information field, the third user information field, etc. in the user information list field. For the user information list field shown in FIG. 9 or FIG. 10 of this implementation, it can be seen that the station can determine a plurality of user information fields that are the same as the association identifier of the station by analyzing all the user information fields one by one.

[0124] 1.2. The amount N of the user information fields of the stations in the trigger frame is configured for the stations in a manner predefined by the protocol or by using signaling.

[0125] In this implementation, the station can select N user information fields of the station from the user information list field in the trigger frame based on N.

[0126] Specifically, for the station to select a plurality of user information fields that are the same as the station's associated identifier from the trigger frame, the station analyzes and determines whether the associated identifier indicated by the associated identifier field in each user information field is the same as the station's associated identifier based on the index of each user information field in the user information list field, and performs the step of analyzing whether the associated identifier indicated by the associated identifier field in each user information field is the same as the station's associated identifier, until the number of user information fields that are the same as the station's associated identifier becomes equal to N, and may include selecting N user information fields that are the same as the station's associated identifier from all the analyzed user information fields. It can be seen that this implementation form ensures the flexibility of expanding the user information fields and reduces the complexity of the station analyzing the user information list field.

[0127] For example, in the user information list field shown in FIG. 9, when the number of user information fields of STA1 in the user information list field is equal to 2, that is, when N = 2, when analyzing the second user information field to determine the two user information fields of STA1, STA1 may stop analyzing the user information list field.

[0128] In another example, in the user information list field shown in FIG. 10, when the maximum number of user information fields of STA1 in the user information list field is equal to 2, that is, when N = 2, when analyzing the third user information field to determine the two user information fields of STA1, STA1 may stop analyzing the user information list field.

[0129] Optionally, the amount N of user information fields of a station in the user information list field is configured for the station or calculated by the access point in a protocol - defined manner or by using signaling. For example, it is assumed that the amount of resource units that can be indicated by each user information field is 1. N may be equal to the amount of resource units that can be allocated, and is configured for the station in a protocol - defined manner or by using signaling.

[0130] 1.3. The user information fields of the same station in the trigger frame are distributed continuously.

[0131] In other words, the user information fields of different stations are distributed continuously in the user information list field. As shown in FIG. 9, after the distribution of the user information field of STA1 in the user information list field is completed, the user information field of STA2 is distributed.

[0132] In this implementation, in step 103, for a station to select a plurality of user information fields that are the same as the station's association identifier from the user information list field may include the station subsequently analyzing, based on the index of each user information field and starting from the first analyzed user information field, whether the association identifier indicated by the association identifier field in each user information field in the user information list field is the same as the station's association identifier until the analysis determines whether the user information fields different from the station's association identifier are analyzed and determined, and then selecting a plurality of user information fields that are the same as the station's association identifier from all the analyzed user information fields. It can be seen that this implementation can reduce the complexity of the station analyzing the user information list field.

[0133] For example, as shown in FIG. 9, both the user information list field of STA1 and the user information field of STA2 are continuously allocated in the user information list field. When the allocation of the user information field of STA2 starts, it indicates that the allocation of the user information field of STA1 has ended. In this way, after analyzing and determining the second user information field, STA1 continues to analyze the third user information field. After determining that the third user information field is not the user information field of STA1, STA1 may stop analyzing subsequent user information fields, that is, it may not need to analyze the user information list field any further.

[0134] 1.4. The user information field includes an end flag.

[0135] Specifically, FIG. 11 is a schematic diagram of the structure of another user information list field according to an embodiment of the present application. In FIG. 11, the user information field further includes an end flag, and the end flag indicates whether the allocation of resource units to the station has ended.

[0136] The end flag may occupy 1 bit. That 1 bit may be 1 bit of a reserved field in the user information field, 1 bit newly added to the user information field, or 1 bit of other information that is reused. This is not limited in the embodiments of the present application.

[0137] The end flag may also be referred to as an end flag area, end flag information, end flag indication, etc. A value of 1 for the end flag may indicate that the allocation of resource units to the station using the user information field where the end flag is located has ended. A value of 0 for the end flag may indicate that the allocation of resource units to the station using the user information field where the end flag is located has not ended, that the station needs to further analyze the next information field, or vice versa.

[0138] In this implementation form, for the station to select a plurality of user information fields that are the same as the association identifier of the station from the user information list field, the station sequentially analyzes whether the association identifier indicated by the association identifier field in each user information field is the same as the association identifier of the station based on the index of each user information field in the trigger frame, and stops analyzing whether the association identifier indicated by the association identifier field in each user information field is the same as the association identifier of the station until the end flag in the analyzed user information field indicates that the allocation of resource units to the station is completed, and may include selecting a plurality of user information fields that are the same as the association identifier of the station from all the analyzed user information fields.

[0139] It is assumed that the value of the end flag being 1 indicates that the allocation of resource units to the station using the user information field where the end flag is located is completed. As shown in FIG. 9, when the second user information list field is the last user information field among the user information fields for allocating resource units to STA1, the AP may set the value of the end flag to 1 in the second user information field. In this way, when analyzing the second user information field and reading that the value of the end flag is 1, the station may stop analyzing the user information list field. In other words, the station does not need to analyze the third user information field and the user information fields after the third user information field. Correspondingly, since the first user information field is not the last user information field among the user information fields for allocating resource units to STA1, the value of the end flag may be set to 0 in the first user information field. In this way, after analyzing and determining the first user information field, STA1 may continue to analyze and determine the second user information field.

[0140] As shown in FIG. 10, when the third user information list field is the last user information field in the user information fields for allocating resource units to STA1, the AP may set the value of the end flag to 1 in the third user information field. In this way, when analyzing the third user information field and reading that the value of the end flag is 1, the station may stop analyzing and determining the user information list field. In other words, the station does not need to analyze the fourth user information field and the user information fields after the fourth user information field. Correspondingly, since the first user information field is not the last user information field in the user information fields for allocating resource units to STA1, the value of the end flag may be set to 0 in the first user information field. In this way, after analyzing and determining the first user information field, STA1 may continue to analyze and determine the second user information field. In addition, in FIG. 10, after analyzing the second user information field and determining that the second user information field is not the user information field of STA1, STA1 may continue to analyze and determine the third user information field.

[0141] In addition, the method by which the station selects a plurality of user information fields of the station from the user information list field may include any one or more of the foregoing implementation forms described in 1.1 to 1.4, but is not limited to those implementation forms.

[0142] The manner in which the station determines one or more resource units indicated by each of the plurality of selected user information fields may be described by using any of the following optional implementation forms in the embodiments of the present application, but the following implementation forms are not limited thereto.

[0143] 2.1. Each user information field indicates one resource unit.

[0144] The user information field may indicate one resource unit. For example, the resource unit allocation subfield shown in FIG. 2 indicates a resource unit. In other words, the resource unit indication and the frequency band range indication included in the user information field may be included in the resource unit allocation subfield.

[0145] In this implementation, it can be seen that regardless of the range of the bandwidth of the combination of resource units and the amount of RUs required, the amount of the user information field can indicate the same amount of RUs respectively.

[0146] In this implementation, the station may be notified of the association between the resource unit and the index in a manner predefined by the protocol or in a signaling configuration manner. The AP may indicate one of the indexes by using the resource unit allocation subfield so that the station can determine the corresponding resource unit based on the index indicated by the resource unit allocation subfield.

[0147] The bandwidth of the wireless local area network may include 20 MHz, 40 MHz, 80 MHz, 160 MHz, 240 MHz, 320 MHz, etc. When allocating resource units to a station for a bandwidth of 20 MHz, 40 MHz, or 80 MHz, the AP may directly indicate one resource unit within that bandwidth by using the resource unit allocation subfield. For a bandwidth of 160 MHz or more, such as 160 MHz, 240 MHz, or 320 MHz, the AP needs to use the resource unit allocation subfield to indicate the 80 MHz bandwidth within that bandwidth where the resource unit is located. Therefore, the resource unit allocation subfield may include a frequency band range indication and a resource unit indication.

[0148] The frequency band range indication indicates the frequency band range in which the resource unit indicated by the resource unit indication is located, and the resource unit indication indicates one allocated resource unit. Optionally, if the size of the resource unit indicated by the resource unit indication is greater than 80 MHz, or if the amount of subcarriers included in the resource unit indicated by the resource unit indication is more than 996, for example, in the case of a 2×996-tone RU, the frequency band range indication may be ignored, that is, the station does not need to analyze the frequency band range indication.

[0149] Table 2 shows the relationship between the value of the frequency band range indication, the bandwidth, and the frequency band range provided in the embodiments of the present application. As shown in Table 2, for bandwidths of 20 MHz, 40 MHz, and 80 MHz, the resource unit allocation subfield may not include the frequency band range indication. For a bandwidth of 160 MHz, the frequency band range indication in the resource unit allocation subfield may occupy 1 bit, that is, the amount of bits required is 1. That the frequency band range indication is equal to 0 indicates that the resource unit indicated by the resource unit indication is located in the primary 80 MHz within the bandwidth, or that the resource unit indicated by the resource unit indication is one resource unit within the primary 80 MHz. That the frequency band range indication is equal to 1 indicates that the resource unit indicated by the resource unit indication is located in the secondary 80 MHz within the bandwidth, or that the resource unit indicated by the resource unit indication is one resource unit within the secondary 80 MHz. For a bandwidth of 320 MHz, the frequency band range indication in the resource unit allocation subfield may occupy 2 bits, that is, the amount of bits required is 2. That the frequency band range indication is equal to 0 indicates that the resource unit indicated by the resource unit indication is located in the primary 80 MHz within the bandwidth, or that the resource unit indicated by the resource unit indication is one resource unit within the primary 80 MHz. That the frequency band range indication is equal to 1 indicates that the resource unit indicated by the resource unit indication is located in the secondary 80 MHz within the bandwidth, or that the resource unit indicated by the resource unit indication is one resource unit within the secondary 80 MHz. That the frequency band range indication is equal to 2 indicates that the resource unit indicated by the resource unit indication is located in the third 80 MHz within the bandwidth, or that the resource unit indicated by the resource unit indication is one resource unit within the third 80 MHz.The fact that the frequency band range indication is equal to 3 indicates that the resource unit indicated by the resource unit indication is located in the fourth 80 MHz within the bandwidth, or that the resource unit indicated by the resource unit indication is one of the resource units within the fourth 80 MHz. Additionally, in Table 2, the association between each value of the frequency band range indication and each 80 MHz frequency band range can be adjusted. This is not limited in the embodiments of the present application.

[0150]

Table 2

[0151] The resource unit indication indicates one resource unit. The size of the resource unit can include, but is not limited to, the seven sizes described above. Referring to the schematic diagram of the allocation of resource units in the 80 MHz bandwidth shown in FIG. 5, the 80 MHz frequency band range can include 37 26-tone RUs located at different positions, 16 52-tone RUs located at different positions, 8 106-tone RUs located at different positions, 4 242-tone RUs located at different positions, 2 484-tone RUs located at different positions, or 1 996-tone RU. Additionally, the resource unit indication can alternatively indicate 2×996-tone RU. Therefore, the value of the resource unit indication or the index indicated by the resource unit indication ranges from at least 0 to 68 in order to indicate each of the 68 resource units.

[0152] Table 3 shows the association between the values of the resource unit indication and each resource unit. To indicate 68 resource units, the resource unit indication requires at least 7 bits. Thus, each of the 7-bit values from 0 to 68 may indicate the resource units shown in Table 3, and the values from 69 to 127 may be reserved. Additionally, the association between each value in Table 3 and the indicated resource unit may be adjusted. This is not limited in the embodiments of the present application. For example, the value of the resource unit indication may indicate, in descending order, resource units arranged in descending order, etc. The related content described in Table 3 may include the related textual description of claim 13 of the claims. In other words, this specification describes a case where the first to seventh resource units are replaced with resource units of a corresponding size. For example, the first resource unit is a 996-tone RU, the second resource unit is a 484-tone RU, and the third resource unit is a 242-tone RU. Similarly, the descriptions from Table 2 to Table 13 are also provided by using the corresponding RUs and include the content of the corresponding claims.

[0153]

Table 3

[0154] In this implementation form, the frequency band range indication indicates a frequency band range of 80 MHz within the bandwidth, and the resource unit indication indicates one resource unit. The resource unit can be any resource unit within the frequency band range of 80 MHz or any resource unit within a frequency band range higher than 80 MHz. In other words, each user information field can indicate any resource unit within the frequency band range of 80 MHz or a resource unit within a frequency band range higher than 80 MHz. Therefore, for the multiple selected user information fields in step 103 in this embodiment of the present application, the resource unit allocation sub-field in each user information field can be used to determine one resource unit. In this case, the resource units separately indicated by the multiple user information fields are the multiple resource units allocated to the station.

[0155] When the bandwidth is 20 MHz, 40 MHz, or 80 MHz, in this implementation form, the frequency band range indication can be 0 by default. For each user information field of the station, the station can determine one resource unit based on the resource unit indication. When the bandwidth is 160 MHz or 320 MHz, the frequency band range indication can occupy 1 bit or 2 bits. For each user information field of the station, the station can determine one 80-MHz frequency band range based on the frequency band range indication and determine the corresponding resource unit from the 80-MHz frequency band range based on the resource unit indication.

[0156] Regardless of the size of the bandwidth, the frequency band range indication occupies 2 bits, which are the upper 2 bits in the resource unit allocation sub-field, the resource unit indication occupies 7 bits, which are the lower 7 bits in the resource unit allocation sub-field, and it is assumed that the values of the resource unit indication in Table 3 (Table 3) are in ascending order and have a one-to-one correspondence with the RUs in each row from left to right in Figure 3.

[0157] To simplify the explanation by using examples, the following describes some possible RU combination strategies with reference to the accompanying drawings.

[0158] Figures 12 to 17 are used as examples to illustrate the 52-tone RU and 26-tone RU in a 20-MHz frequency band range within 80 MHz, that is, the combination strategy of the 52-tone RU and 26-tone RU assigned to the station.

[0159] This strategy is to combine the 52-tone RU with the second lowest frequency in the 20-MHz frequency band range within the 80-MHz frequency band range and the 26-tone RU in the 20-MHz frequency band range that is on the same side as and adjacent to the 52-tone RU. The "26-tone RU that is on the same side as and adjacent to the 52-tone RU" is related to the position of the 20-MHz frequency band range within the 80-MHz frequency band range. When the 20-MHz frequency band range is to the left of the center position of the 80-MHz frequency band range, the "26-tone RU that is on the same side as and adjacent to the 52-tone RU" means that "the 26-tone resource unit is on the left side of the 20-MHz frequency band range and adjacent to the 52-tone RU", or when the 20-MHz frequency band range is to the right of the center position of the 80-MHz frequency band range, the "26-tone RU that is on the same side as and adjacent to the 52-tone RU" means that "the 26-tone resource unit is on the right side of the 20-MHz frequency band range and adjacent to the 52-tone RU".

[0160] In this specification, the second lowest-frequency RU, the lowest-frequency RU, the second highest-frequency RU, and the highest-frequency RU are all relative concepts within a frequency range. For example, as shown in FIG. 5, at the first 20 MHz, the second lowest-frequency 52-tone RU is the second 52-tone RU in the second row of FIG. 5, the lowest-frequency 52-tone RU is the first 52-tone RU in the second row of FIG. 5, the second highest-frequency 52-tone RU is the third 52-tone RU in the second row of FIG. 5, and the highest-frequency 52-tone RU is the fourth 52-tone RU in the second row of FIG. 5. Correspondingly, for other RUs, the second lowest-frequency RU, the lowest-frequency RU, the second highest-frequency RU, and the highest-frequency RU are the same, and the details will not be described again here. In addition, in this specification, the low-frequency RU and the high-frequency RU are also relative concepts within a frequency range. Usually, there are two RUs within the frequency range. The low-frequency RU is the RU with a lower frequency among the two RUs, and the high-frequency RU is the RU with a higher frequency among the two RUs. For example, as shown in FIG. 5, at the first 20 MHz, the low-frequency 106-tone RU is the first 106-tone RU in the third row of FIG. 5, and the high-frequency 106-tone RU is the second 106-tone RU in the third row of FIG. 5.

[0161] FIG. 12 is a schematic diagram of a strategy for a combination of 52-tone RUs and 26-tone RUs according to an embodiment of the present application. FIG. 12 shows the RU allocation when 20 MHz is the first 20 MHz or the second 20 MHz within 80 MHz. Therefore, at the 20 MHz shown in FIG. 12, the combination of the second lowest-frequency 52-tone RU and the 26-tone RU that is on the same side as and adjacent to the 52-tone RU at that 20 MHz is shown in FIG. 12.

[0162] FIG. 13 is a schematic diagram of a strategy for another combination of 52-tone RUs and 26-tone RUs according to an embodiment of the present application. FIG. 13 shows the RU allocation when the 20 MHz is the third or fourth 20 MHz within the 80 MHz. In other words, the 20 MHz is on the right side of the center position of the 80 MHz frequency band range. Therefore, in the 20 MHz shown in FIG. 13, the strategy for the combination of the lowest-frequency 52-tone RU and the 26-tone RU that is on the same side as and adjacent to the 52-tone RU within the 20 MHz frequency band range is the combination of the lowest-frequency 52-tone RU and the 26-tone RU that is on the right side of the 52-tone RU and adjacent thereto.

[0163] FIG. 14 is a schematic diagram of yet another combination strategy of 52-tone RUs and 26-tone RUs according to an embodiment of the present application. FIG. 14 shows the RU allocation when the 20 MHz is the third or fourth 20 MHz within the 80 MHz. In other words, the 20 MHz is on the right side of the center position of the 80 MHz frequency band range. Therefore, in the 20 MHz shown in FIG. 14, the strategy for the combination of the second-highest-frequency 52-tone RU and the 26-tone RU that is on the same side as and adjacent to the 52-tone RU within the 20 MHz frequency band range is the combination of the second-highest-frequency 52-tone RU and the 26-tone RU that is on the right side of the 52-tone RU and adjacent thereto.

[0164] FIG. 15 is a schematic diagram of yet another combination strategy of 52 - tone RUs and 26 - tone RUs according to an embodiment of the present application. FIG. 15 shows the RU allocation when the 20 MHz is the first 20 MHz or the second 20 MHz within the 80 MHz. In other words, the 20 MHz is on the left side of the center position of the 80 MHz frequency band range. Therefore, in the 20 MHz shown in FIG. 15, the combination strategy of the highest - frequency 52 - tone RU and the 26 - tone RU that is on the same side as and adjacent to the 52 - tone RU within the 20 MHz frequency band range is the combination of the highest - frequency 52 - tone RU and the 26 - tone RU that is on the left side of the 20 MHz frequency band range and adjacent to the 52 - tone RU.

[0165] FIG. 16 is a schematic diagram of yet another combination strategy of 52 - tone RUs and 26 - tone RUs according to an embodiment of the present application. FIG. 16 shows the RU allocation when the 20 MHz is the 20 MHz frequency band range within the 80 MHz. As shown in FIG. 16, the combination strategy of the second - lowest - frequency 52 - tone RU within the 20 MHz frequency band range and the 26 - tone RU at the center of the 20 MHz frequency band range is the combination of the second - lowest - frequency 52 - tone RU and the 26 - tone RU at the center of the 20 MHz frequency band range.

[0166] FIG. 17 is a schematic diagram of yet another combination strategy of 52 - tone RUs and 26 - tone RUs according to an embodiment of the present application. FIG. 17 shows the RU allocation when the 20 MHz is the 20 MHz frequency band range within the 80 MHz. As shown in FIG. 17, the combination strategy of the second - highest - frequency 52 - tone RU within the 20 MHz frequency band range and the 26 - tone RU at the center of the 20 MHz frequency band range is the combination of the second - highest - frequency 52 - tone RU and the 26 - tone RU at the center of the 20 MHz frequency band range.

[0167] Figures 18 and 19 are used as examples to illustrate the strategy of the combination of 106-tone RUs and 26-tone RUs in a 20-MHz frequency band range within 80 MHz, that is, the combination of 106-tone RUs and 26-tone RUs assigned to a station.

[0168] Figure 18 is a schematic diagram of the combination of 106-tone RUs and 26-tone RUs according to an embodiment of the present application. Figure 18 shows the RU allocation in a 20-MHz frequency band range within 80 MHz. Figure 18 shows the strategy of the combination of a low-frequency 106-tone RU in the 20-MHz frequency band range and a 26-tone RU at the center of the 20-MHz frequency band range.

Figure 19 shows the RU allocation in a 20-MHz frequency band range within 80 MHz. Figure 19 shows the strategy of the combination of a high-frequency 106-tone RU in the 20-MHz frequency band range and a 26-tone RU at the center of the 20-MHz frequency band range.

[0179] Figures 27 and 28 are each a schematic diagram of a combination of 996-tone RUs, 484-tone RUs, and 242-tone RUs, but are not limited to the combination strategy.

[0181] FIG. 28 is a schematic diagram of a combination of 996-tone RUs, 484-tone RUs, and 242-tone RUs according to an embodiment of the present application.

[0182] In addition, in this specification, that two frequency band ranges are "adjacent at a lower frequency" or "adjacent at a higher frequency" to each other means that those two frequency band ranges are the closest. For example, in FIG. 27, with respect to the second 80-MHz frequency band range, the first 80-MHz frequency band range can be called a frequency band range adjacent at a lower frequency to the second 80-MHz frequency band range. With respect to the first 80-MHz frequency band range, the second 80-MHz frequency band range can be called a frequency band range adjacent at a higher frequency to the first 80-MHz frequency band range.

[0183] FIGS. 29 and 30 are each a schematic diagram of a combination of 996-tone RUs, 242-tone RUs, and 242-tone RUs, but are not limited to the combination strategy.

[0184] Figure 29 is a schematic diagram of a combination of 996-tone RUs, 242-tone RUs, and 242-tone RUs according to an embodiment of the present application. Figure 29 shows the RU allocation at 80 MHz indicated by the frequency band range indication and at 80 MHz of a higher frequency adjacent to that 80 MHz.

[0186] Figure 31 is a schematic diagram of a combination of 484-tone RUs, 242-tone RUs, 484-tone RUs, and 242-tone RUs according to an embodiment of the present application. Figure 31 shows the RU allocation at 80 MHz indicated by the frequency band range indication and at 80 MHz of a higher frequency adjacent to that 80 MHz.

[0187] There are four strategies for selecting 484-tone RUs and 242-tone RUs within 80 MHz. As shown in FIGS. 20 to 23, there are two 80-MHz frequency band ranges between the 80 MHz indicated by the frequency band range indication and the 80 MHz adjacent to that 80 MHz. Therefore, 4×4 = 16, that is, there can be 16 combinations of strategies for 484-tone RUs, 242-tone RUs, 484-tone RUs, and 242-tone RUs. Details are not described in this specification.

[0188] FIGS. 32 to 36 are each schematic diagrams of combinations of three 996-tone RUs in a 320-MHz frequency band range.

The RU allocation shown in Figure 35 is the RU allocation at 320 MHz. At 320 MHz, a combination of the three 996-tone RUs with the highest frequencies is shown in Figure 35.

[0193] Figure 36 is a schematic diagram of a combination of four 996-tone RUs according to an embodiment of the present application. The RU allocation shown in Figure 36 is the RU allocation at 320 MHz. At 320 MHz, a combination of four 996-tone RUs is shown in Figure 36.

[0194] Figures 37 to 39 are each a schematic diagram of a combination of two 996-tone RUs according to an embodiment of the present application. The two 996-tone RUs include at least one 996-tone RU corresponding to the primary 80 MHz.

[0195] Figure 37 is a schematic diagram of a combination of two 996-tone RUs according to an embodiment of the present application. The RU allocation shown in Figure 37 is the RU allocation at 320 MHz. At 320 MHz, a combination of a 996-tone RU corresponding to the 80 MHz (for example, the first 80 MHz) indicated by the frequency band range indication and another 996-tone RU corresponding to the first 80 MHz is shown in Figure 37.

[0196] Figure 38 is a schematic diagram of another combination of two 996-tone RUs according to an embodiment of the present application. The RU allocation shown in Figure 38 is the RU allocation at 320 MHz. At 320 MHz, a combination of a 996-tone RU corresponding to the 80 MHz (for example, the first 80 MHz) indicated by the frequency band range indication and another 996-tone RU corresponding to the second 80 MHz is shown in Figure 38.

[0197] FIG. 39 is a schematic diagram of another combination of two 996-tone RUs according to an embodiment of the present application. The RU allocation shown in FIG. 39 is the RU allocation at 320 MHz. At 320 MHz, a combination of a 996-tone RU corresponding to 80 MHz (for example, the first 80 MHz) indicated by a frequency band range indication and another 996-tone RU corresponding to the third 80 MHz is shown in FIG. 39.

[0198] FIGS. 12 to 39 are schematic diagrams of some possible RU combination strategies. In the resource allocation method of the present application, the RU combination strategies shown in FIGS. 12 to 39 are used as examples to illustrate how to provide instructions for a station in order to allocate a plurality of resource units to the station.

[0199] Optionally, the RU combination strategies of FIGS. 12 to 39 are applicable to the configuration of resource units in uplink transmission, or the configuration of resource units in PPDU transmission, for example, the configuration of a Single-User PPDU (SU PPDU), a Multi-User PPDU (MU PPDU), or an Extended-Range PPDU (ER PPDU).

[0200] In this implementation, the user information list field includes a plurality of user information fields that are the same as the associated identifier of the station. Each user information field indicates one resource unit. The frequency band range indication in the resource unit allocation subfield may indicate 80 MHz in the bandwidth, and the resource unit indication may indicate one of the resource units by using the association shown in Table 3.

[0201] For example, in the user information list field shown in FIG. 9, the AP sets the resource unit allocation subfield in the first user information field to 000000001. In this case, STA1 can analyze the first user information field and determine that the frequency band range indication (higher-order bits 00) in the resource unit allocation subfield indicates the first 80 MHz and that the resource unit indication (lower-order bits 0000001) indicates the second 26-tone RU in the first row of FIG. 3. In addition, the AP sets the resource unit allocation subfield in the second user information field to 000100110. In this case, STA1 can analyze the second user information field and determine that the frequency band range indication (higher-order bits 00) in the resource unit allocation subfield indicates the first 80 MHz and that the resource unit indication (lower-order bits 0100110) indicates the second 52-tone RU in the second row of FIG. 5. Since STA1 can determine that the user information list field does not include the user information field of STA1 based on the implementation forms described in 1.1 to 1.4, finally, STA1 can determine that the plurality of RUs allocated to STA1 are the second 26-tone RU in the first row of FIG. 5 and the second 52-tone RU in the second row of FIG. 5.

[0202] Similarly, the policies for combining two resource units shown in FIGS. 12 to 26 and the policies for combining two resource units shown in FIGS. 37 to 39 can alternatively provide instructions based on the associations shown in Table 2 and Table 3, so that the station can obtain a plurality of allocated resource units. Details are not described again here.

[0203] Regarding the strategy of combining three resource units shown in FIGS. 27 to 34, the user information list field may include three user information fields that are the same as the associated identifier of the station. Therefore, the values of the frequency band range indication and the resource unit allocation indication in each resource unit allocation subfield can be determined separately by using the three user information fields and the associations shown in Table 2 and Table 3. Correspondingly, the station obtains three user information fields of the station from the user information list field by using the implementation forms shown in 1.1 to 1.4, and then determines three allocated resource units based on Table 2 and Table 3, and can determine the values of the user information fields in this implementation form.

[0204] In this implementation form, the user information field is used to allocate a plurality of RUs to a single station, and the station can correctly analyze the RU allocation information. This helps to achieve backward compatibility with conventional receiving STAs.

[0205] 2.2. One user information field indicates a plurality of resource units.

[0206] In some cases, a method in which one user information field is required to indicate every 80 MHz is used. In this case, up to two user information fields are required to indicate the combination of RUs in the frequency band range higher than 80 MHz and up to 160 MHz. Up to four user information fields are required to indicate the combination of RUs in the frequency band range higher than 160 MHz and up to 320 MHz. In this implementation form, the combination of a plurality of RUs within 80 MHz can be indicated by using one user information field.

[0207] In other cases, a method is used in which one user information field is required to indicate every 160 MHz. In this case, to indicate the RU combination in a frequency band range of 160 MHz or less, at most one user information field is required. To indicate the RU combination in a frequency band range higher than 160 MHz and 320 MHz or less, at most two user information fields are required. In this implementation form, the combination of a plurality of RUs in the frequency band range of 160 MHz or less can be indicated by using one user information field in 160 MHz.

[0208] When four RUs in the 160 MHz frequency band range, for example, 484 - tone RU, 242 - tone RU, 484 - tone RU, and 242 - tone RU are combined, to indicate the combination of one 484 - tone RU and one 242 - tone RU, one user information field is required to indicate every 80 MHz. In this case, two user information fields can indicate the combination of four RUs.

[0209] In addition, when three 996 - tone RUs are combined, each 996 - tone RU is indicated by using one user information field, and three user information fields may be required to indicate the combination of three 996 - tone RUs.

[0210] Optionally, when the bandwidth range indicated by one user information field is not limited regardless of the bandwidth range of the combination of resource units, one user information field indicates a plurality of resource units.

[0211] 2.2. Association between a plurality of resource units indicated by one user information field and an index

[0212] In this implementation form, the resource unit indication in the resource unit allocation subfield may indicate a plurality of resource units (this is called a combination of a plurality of resource units for simplicity of explanation). The protocol may notify the association between the possible combinations of a plurality of resource units and the index in a defined manner or in a signaling configuration manner. The AP may indicate one of the indexes by using the resource unit indication so that the station can determine the combination of a plurality of resource units based on the index indicated by the resource unit indication.

[0213] In other words, different from Implementation Form 2.1, in Implementation Form 2.2, the resource unit indication indicates a combination of a plurality of resource units. Table 4 shows the association shown in Table 3 and further includes the meaning indicated by the values 69 to 127 of the resource unit indication, that is, it indicates a combination of a plurality of resource units.

[0214] [Table 4A]

[0215] [Table 4B]

[0216] [Table 4C]

[0217] [Table 4D]

[0218] [Table 4E]

[0219]

Table 4F

[0220] In an optional implementation, the resource unit allocation subfield includes a resource unit indication, and the resource unit indication indicates a plurality of resource units. In Table 4, when the value or index indicated by the resource unit indication is 71 or any number between 107 and 110, the station does not have to analyze which 80 MHz is indicated by the frequency band range indication.

[0221] Correspondingly, in step 104, for the station to determine a plurality of resource units indicated by each user information field based on the resource unit allocation subfield means that for each user information field, the station determines a plurality of resource units indicated by the resource unit indication as the plurality of resource units indicated by the user information field.

[0222] In another optional implementation, the resource unit allocation subfield includes a resource unit indication and a frequency band range indication. The frequency band range indication indicates 80 MHz, and the resource unit indication indicates a plurality of resource units. Correspondingly, in step 104, for the station to determine a plurality of resource units indicated by the user information field based on the resource unit allocation subfield means that the station determines the frequency band range indicated by the frequency band range indication, and based on the resource unit indication, determines two resource units within the frequency band range and two resource units within the lower frequency band range adjacent to the frequency band range or within the higher frequency band range adjacent to the frequency band range, and uses these four determined resource units as the plurality of resource units indicated by the user information field.

[0223] For example, in Table 4, when the value or index indicated by the resource unit indication is any number between 111 and 126, after determining the frequency band range indicated by the frequency band range indication, the station further determines another lower frequency band range of 80 MHz adjacent to the frequency band range, or another higher frequency band range of 80 MHz adjacent to the frequency band range, and it is necessary to determine a combination of a plurality of resource units based on the index indicated by the resource unit indication.

[0224] In yet another optional implementation, in step 104, the station determining a plurality of resource units indicated by each user information field based on the resource unit allocation subfield includes, for each user information field, the station determining the frequency band range indicated by the frequency band range indication, and determining that the plurality of resource units indicated by the resource unit indication are one or more resource units in the frequency band range corresponding to the frequency band range and in the frequency band range adjacent to the resource units corresponding to the frequency band range. For example, in Table 4, when the value or index indicated by the resource unit indication is any number between 68 and 70 or between 101 and 106, the station may determine a plurality of resource units indicated by the user information field in this implementation.

[0225] In yet another optional implementation, in step 104, the station determining a plurality of resource units indicated by each user information field based on the resource unit allocation subfield includes the station determining the frequency band range indicated by the frequency band range indication and determining a plurality of resource units indicated by the resource unit indication from the frequency band range. For example, in Table 4, when the value or index indicated by the resource unit indication is any number between 72 and 100, the station may determine a plurality of resource units indicated by the user information field in this implementation.

[0226] In 2.2.1, it can be seen that the resource unit is allocated to the station by using the frequency band range indication, the resource unit indication, and the relevant content of Table 4 (Table 4), and there is no need to add new bits. This helps to reduce the resource overhead.

[0227] 2.2.2 The user information field includes a frequency band range indication, a resource unit indication, and a resource unit combination indication.

[0228] In this implementation form, the user information field can also indicate a plurality of resource units by using three indications. The frequency band range indication indicates a frequency band range of 80 MHz. Optional values or indexes are shown in Table 2 (Table 2), and the details are not described again here. The resource unit indication indicates one resource unit within the frequency band range. Optional values or indexes are shown in Table 3 (Table 3), and the details are not described again here. The resource unit combination indication indicates a combination of a plurality of resource units, and the combination of a plurality of resource units includes the resource units indicated by the resource unit indication. The combination of a plurality of resource units is used as the plurality of resource units indicated by the user information field. The resource unit combination (RU combination) indication may also be referred to as a resource unit combination area, a resource unit combination field, a combination area, a combination field, etc.

[0229] The resource unit combination indication may occupy 1 bit, 2 bits, 3 bits, etc. Optionally, the amount of bits occupied by the resource unit combination indication is related to the amount of the resource unit combination policy. The policy of the combination of resource units is the policy of the combination of resource units indicated by the resource unit indication. In addition, the position of the bits occupied by the resource unit combination indication is not limited and may be continuous or discontinuous.

[0230] The bits occupied by the resource unit combination indication can be newly added to the user information field, use the reserved field, or reuse other information fields. For example, FIG. 40 is a schematic diagram of the structure of the user information field according to an embodiment of the present application. As shown in FIG. 40, the trigger frame type-dependent local information field includes a multi-user separation factor (MPDU MU Spacing Factor), a traffic identification subset aggregation limit (TID Aggregation Limit), a resource unit combination indication bit 1 (RU Combination Bit 1), and a preferred access category (Preferred AC). The resource unit combination indication occupies 2 bits. The resource unit combination indication bit 0 may be a reserved bit in the user information field shown in FIG. 2, and the resource unit combination indication bit 1 may be 1 bit in the trigger frame type-dependent local information field in the user information field shown in FIG. 40.

[0231] In the structure shown in FIG. 40, the resource unit allocation subfield (i.e., the frequency band range indication and the resource unit indication) and the resource unit combination indication are two independent fields. In other implementations, the resource unit allocation subfield and the resource unit combination indication can be combined into one field. In other words, the multiple functions of the frequency band range indication, the resource unit indication, and the resource unit combination indication are implemented by using one field. This one field can be implemented by extending the original resource unit allocation subfield or by using reserved bits.

[0232] Correspondingly, the base station determining a plurality of resource units indicated by the user information field means that the base station determines a combination of a plurality of resource units as the plurality of resource units indicated by the user information field based on the resource unit combination indication and the resource units indicated by the resource unit indication.

[0233] The following is described by using an example in which the resource unit combination indication occupies 2 bits, and the strategy of combining 106 - tone RU and 26 - tone RU is shown in FIGS. 18 and 19. The resource unit indication can indicate a 106 - tone RU by using Table 2 and Table 3. The correspondence between the value or index of the resource unit combination indication and each explanation or meaning is shown in Table 5.

[0234] For example, when the frequency band range indication is 00 and the resource unit indication is 53, it can be understood from Table 2 and Table 3 that the resource unit indicated by the resource unit indication is the first 106 - tone RU in the third row of FIG. 5. As shown in FIG. 18, when the resource unit combination indication is 01, the user information field indicates a plurality of RUs, and the plurality of RUs are the first 106 - tone RU in the third row of FIG. 5 and the fifth 26 - tone RU in the first row of FIG. 3.

[0235] In another example, when the frequency band range indication is 00 and the resource unit indication is 54, it can be understood from Table 2 and Table 3 that the resource unit indicated by the resource unit indication is the second 106 - tone RU in the third row of FIG. 5. As shown in FIG. 19, when the resource unit combination indication is 01, the user information field indicates a plurality of RUs, and the plurality of RUs are the second 106 - tone RU in the third row of FIG. 5 and the fifth 26 - tone RU in the first row of FIG. 3.

[0236]

Table 5

[0237] The following is described by using an example where the resource unit combination indication occupies 2 bits, and the strategies for combinations of 52-tone RUs and 26-tone RUs are shown in FIGS. 12 to 17. The resource unit indication can indicate a 52-tone RU by using Table 2 and Table 3. The correspondence between the values or indices of the resource unit combination indication and their respective explanations or meanings is shown in Table 6. For "on the same side and adjacent", refer to the descriptions in FIGS. 12 to 17. Details are not described again here.

[0238] For example, the resource unit indication can indicate the second 52-tone RU in the second row of FIG. 5 by using Table 2 and Table 3. In other words, as shown in FIG. 16, when the frequency band range indication is 00 and the resource unit indication is 38, and the resource unit combination indication is 01, the user information field indicates a plurality of RUs, and the plurality of RUs are the second 52-tone RU in the second row of FIG. 5 and the fifth 26-tone RU in the first row of FIG. 3. As shown in FIG. 12, when the resource unit combination indication is 10, the user information field indicates a plurality of RUs, and the plurality of RUs are the second 52-tone RU in the second row of FIG. 5 and the second 26-tone RU in the first row of FIG. 5.

[0239] A similar indication method can be used for other combination strategies of 52-tone RUs and 26-tone RUs so that the station can determine a plurality of resource units indicated by the user information field according to three displays.

[0240]

Table 6

[0241] The following is described by using an example where the resource unit combination indication occupies 2 bits, and the strategies for combinations of 484-tone RUs and 242-tone RUs are shown in FIGS. 20 to 23. The resource unit indication can indicate a 484-tone RU by using Table 2 and Table 3. The correspondence between the values or indices of the resource unit combination indication and their respective descriptions or meanings is shown in Table 7.

[0242] For example, the resource unit indication can indicate the first 484-tone RU in the fifth row of FIG. 5 by using Table 2 and Table 3. In other words, as shown in FIG. 20, when the frequency band range indication is 00 and the resource unit indication is 65, if the resource unit combination indication is 01, the user information field indicates a plurality of RUs, and the plurality of RUs are the first 484-tone RU in the fifth row of FIG. 5 and the third 242-tone RU in the fourth row of FIG. 3. As shown in FIG. 22, when the resource unit combination indication is 10, the user information field indicates a plurality of RUs, and the plurality of RUs are the first 484-tone RU in the fifth row of FIG. 5 and the fourth 26-tone RU in the fourth row of FIG. 5.

[0243] A similar indication method can be used for other combination strategies of 484-tone RUs and 242-tone RUs so that the station can determine a plurality of resource units indicated by the user information field according to three displays. Details are not described again here.

[0244]

Table 7

[0245] The following is described by using an example where the resource unit combination indication occupies 2 bits, and the strategy of combining a 242-tone RU and a 242-tone RU is shown in FIG. 24. The association between the value or index of the resource unit combination indication and each explanation or meaning is shown in Table 8.

[0246] For example, the resource unit indication can indicate the first 242-tone RU in the fourth row of FIG. 5 by using Table 2 and Table 3. In other words, as shown in FIG. 24, when the frequency band range indication is 00 and the resource unit indication is 61, if the resource unit combination indication is 01, the user information field indicates a plurality of RUs, and the plurality of RUs are the first 242-tone RU in the fourth row of FIG. 5 and the last 242-tone RU in the fourth row of FIG. 5. If the resource unit combination indication is 00, the user information field indicates one RU, which is the first 242-tone RU in the fourth row of FIG. 5.

[0247] [Table 8]

[0248] The following is described by using an example where the resource unit combination indication occupies 2 bits, and the strategy of combining a 996-tone RU and a 484-tone RU is shown in FIGS. 25 and 26. The association between the value or index of the resource unit combination indication and each explanation or meaning is shown in Table 9.

[0249] For example, as shown in FIG. 25, when the frequency band range indication is 00 and the resource unit indication is 67, if the resource unit combination indication is 01, the user information field indicates a plurality of RUs, and the plurality of RUs are the first 996 - tone RU in the third row of FIG. 25 and the last 484 - tone RU in the second row of FIG. 25. If the resource unit combination indication is 10, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 28. If the resource unit combination indication is 11, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 29.

[0250]

Table 9

[0251] The following is described by using an example where the resource unit combination indication occupies 2 bits, and the combination strategy is shown in FIGS. 25 to 30. The correspondence between the value or index of the resource unit combination indication and each explanation or meaning is shown in Table 10. The currently shown 996 - tone RU is the 996 - tone RU determined based on the frequency band range indication and the resource unit indication. Optionally, in Table 10, in the combination of a plurality of RUs in a frequency band range higher than 80 MHz, the resource unit indication may be required to indicate the 996 - tone RU with the lowest frequency, for example, the 996 - tone RU corresponding to the primary 80 MHz. Optionally, the resource unit indication in Table 10 may also indicate any 80 MHz in its bandwidth.

[0252]

[0253] For example, when the frequency band range indication is 01 and the resource unit indication is 67, if the resource unit combination indication is 000, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 26.In another example, when the frequency band range indication is 00 and the resource unit indication is 67, if the resource unit combination indication is 001, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 25.

[0254] In another example, when the frequency band range indication is 01 and the resource unit indication is 67, if the resource unit combination indication is 010, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 28.

[0255] In another example, when the frequency band range indication is 00 and the resource unit indication is 67, if the resource unit combination indication is 011, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 27.

[0256] In another example, when the frequency band range indication is 00 and the resource unit indication is 67, if the resource unit combination indication is 100, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 34.

[0257] In another example, when the frequency band range indication is 11 and the resource unit indication is 67, if the resource unit combination indication is 101, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 32.

[0258] In another example, when the frequency band range indication is 00 and the resource unit indication is 67, if the resource unit combination indication is 110, the plurality of RUs indicated by the user information field are the combination of RUs shown in FIG. 33.

[0259]

Table 10

[0260] Optionally, the resource unit combination indication may also indicate a combination of 996-tone RUs other than the 996-tone RU indicated by the resource unit indication.

[0261] Optionally, the resource unit combination indication may occupy 1 bit. In the resource unit combination indication shown in Table 6, 1 bit may separately indicate that there is no RU combined with the RU indicated by the resource unit indication, and that the RU indicated by the resource unit indication is combined with a 26-tone RU. For details, please refer to Table 11.

[0262] [Table 11]

[0263] Optionally, the 1 bit occupied by the resource unit combination indication may indicate whether a 26-tone RU at the center of 20 MHz where the 52-tone RU is located is combined with that 52-tone RU, as shown in Table 12. Comparing with the combination strategy shown in Table 6, it can be seen that the combination strategy shown in Table 12 can reduce the required bit overhead.

[0264] [Table 12]

[0265] Optionally, the 1 bit occupied by the resource unit combination indication may indicate whether a 26-tone RU on the same side as and adjacent to the 52-tone RU is combined with that 52-tone RU, as shown in Table 13. Comparing with the combination strategy shown in Table 6, it can be seen that the combination strategy shown in Table 13 can reduce the required bit overhead.

[0266]

Table 13

[0267] Similarly, the 1 bit occupied by the resource unit combination indication may indicate whether the 484-tone RU in Table 7 (Table 7) is combined with the 242-tone RU adjacent to the 484-tone RU or whether the 484-tone RU in Table 7 (Table 7) is combined with the 242-tone RU not adjacent to the 484-tone RU. In Table 8 (Table 8), the 1 bit may also indicate the combination of 242-tone RU and 242-tone RU. For example, when the value of the resource unit combination indication is 0, it indicates a single 242-tone RU. When the value of the resource unit combination indication is 1, it indicates two 242-tone RUs.

[0268] In this implementation, when a plurality of resource units are assigned to one station, it can be seen that the trigger frame does not require two user information fields for indication, but only one user information field is required for indication. In other words, the user information field corresponding to one resource unit that needs to be assigned to the station, or one user information field corresponding to the station, may indicate the combination and assignment of multiple RUs.

[0269] It can be seen that the amount of bits occupied by the resource unit combination indication can be determined based on the RU combination strategy and selection flexibility. In this implementation, regardless of the bandwidth size, one user information field can indicate a combination of multiple resource units. Alternatively, for a large bandwidth, two user information fields can indicate the RU combination strategy at 80 MHz corresponding to each user information field. The first part describes how to select multiple user information fields in the user info list field that is the same as the local association identifier, or an optional implementation. For multiple user information fields, each user information field may indicate one resource unit in the aforementioned implementation 2.1, or may indicate a combination of multiple resource units in the aforementioned implementation 2.2.1 or 2.2.2. Therefore, multiple resource units can be allocated to the local in the first part.

[0270] 2. The trigger frame includes one user information field that is the same as the local association identifier.

[0271] In this implementation, one user information field can be used to constitute multiple resource units for the local. The user information field can be the user information field in the aforementioned implementation 2.2.1 or 2.2.2 for indicating multiple resource units.

[0272] The user information field may include a frequency band range indication and a resource unit indication. Alternatively, the user information field may include a frequency band range indication, a resource unit indication, and a resource unit combination indication.

[0273] Figure 41 is a schematic flowchart of a resource allocation method according to an embodiment of the present application. As shown in Figure 41, the resource allocation method includes the following steps.

[0274] 201: Determine a plurality of resource units to which the access point is assigned to the station.

[0275] 202: The access point transmits a trigger frame, and the trigger frame includes one user information field that is the same as the association identifier of the station, and the user information field indicates a plurality of resource units assigned to the station.

[0276] 203: The station receives the trigger frame and determines a plurality of assigned resource units based on the trigger frame.

[0277] The station determines a plurality of resource units to be assigned based on the trigger frame, which includes the station selecting one user information field that is the same as the association identifier of the station from the user information list field, the association identifier of the station being the same as the association identifier indicated by the association identifier field, determining the plurality of resource units indicated by the user information field, and the plurality of resource units indicated by the user information field being the plurality of resource units assigned to the station.

[0278] The manner in which the station selects one user information field that is the same as the association identifier of the station from the user information list field may be any optional implementation form of the foregoing implementation forms 1.1 to 1.4, but is not limited to the foregoing implementation forms.

[0279] For the manner in which the station determines a plurality of resource units indicated by the resource unit assignment subfield, refer to the relevant descriptions of the foregoing implementation forms 2.2.1 and 2.2.2. Details are not described again here.

[0280] In the embodiment of the present application, when the range of the combination of RUs indicated by one user information field is not limited regardless of the range of the bandwidth of the combination of RUs, one user information field may indicate a policy for the combination of RUs.

[0281] For example, the user information field in the aforementioned implementation form 2.2.1 may indicate a combination of multiple RUs within 80 MHz, for example, a combination of RUs that can be indicated when the resource unit indication value in Table 4 is any number between 72 and 100. Alternatively, the user information field in the aforementioned implementation form 2.2.2 may indicate a combination of 106-tone RUs and 26-tone RUs shown in Table 5, a combination of 52-tone RUs and 26-tone RUs shown in Table 6, a combination of 484-tone RUs and 242-tone RUs shown in Table 7, a combination of 242-tone RUs and 242-tone RUs shown in Table 8, and so on.

[0282] The user information field in the aforementioned implementation form 2.2.1 may indicate a combination of RUs in a frequency band range higher than 80 MHz but not exceeding 160 MHz. When the resource unit indication value is any number between 101 and 106 in Table 4, the policy of the combination of RUs in this range can be indicated. Alternatively, the user information field in the aforementioned implementation form 2.2.2 may indicate a combination of RUs in a frequency band range higher than 80 MHz but not exceeding 160 MHz. As shown in Table 9, the frequency band range indication and the resource unit indication in one user information field may indicate one 996-tone RU, and the resource unit combination indication may indicate the policy of possible combinations of 996-tone RUs.

[0283] The user information field in the aforementioned implementation form 2.2.1 may indicate a combination of RUs in a frequency band range higher than 160 MHz but not exceeding 320 MHz. When the resource unit indication value is any number between 107 and 110 in Table 4, the policy of the combination of RUs in this range can be indicated.

[0284] Alternatively, the user information field in the aforementioned implementation form 2.2.2 may indicate a combination of RUs in a frequency band range higher than 80 MHz. In the method shown in Table 10, the resource unit combination indication may occupy 3 bits, and the 3-bit resource unit combination indication includes 1 bit newly added to the user information field. For example, when the frequency of the RU is higher than 80 MHz, the uplink dual-carrier modulation field may be reused as the resource unit combination indication.

[0285] In implementation form 2.2.2, when the frequency of the RU is 80 MHz or less, it can be seen that the resource unit combination indication may use 2 bits or 1 bit for indication, as shown in Table 5 to Table 8, and Table 11 to Table 13. The resource unit combination indication may use 2 bits to indicate a combination of RUs in a frequency band range higher than 80 MHz but 160 MHz or less. As shown in Table 9, the resource unit combination indication is in the user information field corresponding to the 996-tone RU that needs to be allocated to the station. As shown in Table 10, the resource unit combination indication may use 3 bits to indicate a combination of RUs in a frequency band range higher than 80 MHz.

[0286] Optionally, in Table 10, in a combination of multiple RUs in a frequency band range higher than 80 MHz, it may be required that the resource unit indication can indicate the 996-tone RU with the lowest frequency.

[0287] In the resource allocation method shown in FIG. 41, it can be seen that a plurality of resource units are allocated to the station by using one user information field in order to reduce the overhead of the user information field.

[0288] In addition, in this specification, the resource allocation methods described in the above two parts can be applied to the same network structure. For example, a combination of multiple RUs may be configured for several stations, and one RU may be configured for other stations based on, for example, the amount of data that needs to be transmitted by each station, the priority of the data, etc. This is not limited in the embodiments of this application. The resource allocation methods described in the above two parts can be applied to the same station. For example, a combination of multiple RUs or one RU may be configured for a station based on, for example, the amount of data that needs to be transmitted by the base station at different moments, different priorities of the data, etc. This is not limited in the embodiments of this application.

[0289] In conclusion, this application provides a resource allocation method. The access point transmits a trigger frame to the station. The trigger frame includes a plurality of user information fields that are the same as the association identifier of the station, and each user information field indicates one resource unit allocated to the station for allocating a plurality of resource units to the station as shown in the relevant content of Embodiment 2.1 described above.

[0290] In other resource allocation methods, in order to reduce the usage of the user information field, the trigger frame includes one user information field that is the same as the association identifier of the station, and the user information field indicates a plurality of resource units allocated to the station. The user information field may be the user information field in the foregoing implementation form 2.2.1, and may also indicate a plurality of resource units by using Table 2 (Table 2), Table 3 (Table 3), resource unit indication, and frequency band range indication. The user information field can be redesigned. As described in implementation form 2.2.2, the resource unit combination indication is added to the user information field. Specifically, the resource unit allocation sub-field in the trigger frame is redesigned, and the resource unit combination indication is set by reusing other information fields or reserved fields, or by newly adding bits, in order to indicate a combination of a plurality of resource units as the resource units indicated by the user information field.

[0291] In yet another resource allocation method, the trigger frame includes a plurality of user information fields that are the same as the association identifier of the station, and each user information field indicates a plurality of resource units allocated to the station as shown in implementation forms 2.2.1 and 2.2.2. In this method, it can be seen that when the bandwidth range of the combination of RUs indicated by one user information field is limited, more resource units can be allocated to the station.

[0292] 3. Resource Unit Allocation Method in Downlink Transmission

[0293] This application further provides a resource unit allocation method, which is used to allocate resource units occupied by downlink transmission to stations. The access point may send a PPDU preamble message to the station. As shown in FIG. 42, the PPD preamble message includes a User information field and a Common field. The Common field is used to indicate RU allocation information, and the User information field includes a series of User fields. It should be noted that the User information field is a field in the PPDU preamble message in downlink transmission and is different from the User information field in uplink transmission in the foregoing embodiments.

[0294] Each user field indicates one RU or a combination of multiple RUs and is allocated to the corresponding station.

[0295] As shown in Table 14, the user field may include fields such as a user identifier, a spatial stream configuration, a modulation and coding scheme, and a coding region. In addition, other fields other than the user identifier may also be moved to the last field of the combined user area. The user field further includes newly added consecutive fields and a "number of RUs or RU allocation bitmap" field. The consecutive fields may include 2 bits. A value of 0 for the consecutive fields indicates that a single RU is allocated to the station. In this case, the "number of RUs or RU allocation bitmap" field does not exist. A value of 1 for the consecutive fields indicates that a plurality of consecutive RUs are allocated to the station. In this case, the value of the "number of RUs or RU allocation bitmap" field indicates the amount of RUs allocated to the station. A value of 2 for the consecutive fields indicates that a plurality of non-consecutive RUs are allocated to the station. In this case, the value of the "number of RUs or RU allocation bitmap" field indicates the allocation result of the next X (for example, X is equal to 9) RUs. If one of the next X RUs is allocated to the station, the corresponding bit is set to 1, otherwise the corresponding bit is set to 0. If the value of the allocation bitmap field is 0, it indicates that none of the next X RUs are allocated to the STA, and for reading, it is possible to directly jump to the user field corresponding to the (X + 1)-th RU in the future.

[0296] [Table 14]

[0297] For example, assuming X is equal to 9, the value 2 of the consecutive field indicates that a plurality of non - consecutive RUs are allocated locally, and the user identifier in the first user field in the user information field is the same as the local user identifier. When the value of the RU allocation bitmap field is 010000000, it indicates that the RU corresponding to the third user field in the user information field is allocated locally. When the value of the RU allocation bitmap field is 000000000, it indicates that none of the RUs corresponding to the second user field to the tenth user field in the user information field are allocated locally. The local station needs to jump to the eleventh user field to read whether the user identifier in the eleventh user field is the same as the local identifier. If the user identifier in the eleventh user field is the same as the local identifier, the local station can read the value of the RU allocation bitmap field from the eleventh user field and determine whether the RU corresponding to the twelfth user field to the twentieth user field is the RU allocated locally. Similar operations are performed until the user information field is completely parsed.

[0298] In the resource allocation method, it can be seen that the access point can allocate a plurality of resource units to users in multi - user transmission.

[0299] The foregoing embodiments of the present application explain the method provided in the embodiments of the present application from the perspectives of the access point and the local station.
