[0048] In the embodiments of the present application, the "protocol" may refer to standard protocols in the communications field, which may include, for example, the WiFi protocol and related protocols applied to future WiFi communication systems, and the present application is not limited thereto.

[0049] The "STA" mentioned in the embodiments of the present application may specifically be a "non-AP STA".

[0050] To facilitate a better understanding of the embodiments of the present application, the TXOP sharing mechanism relevant to the present application will be described.

[0051] 802.11be proposes a triggered TXOP sharing procedure, as shown in the scene diagram of Figure 2, in which an AP is allowed to share part of its acquired TXOP with one non-AP STA, and the non-AP STA can send one or more non-trigger-based physical layer protocol data units (non-TB PPDUs) to its associated AP or another STA through the shared TXOP. As shown in Figure 3, the TXOP acquired by the AP can be shared with STA1 so that STA1 can send a non-TB PPDU to smart glass1 (G1).

[0052] Specifically, as shown in FIG. 3, the AP shares the resource units (RUs) in the TXOP it acquires with STA1 via a Multiple Users Request-To-Send Transmission Opportunity Sharing Trigger Frame (MU-RTS TXS TF). The MU-RTS TXS TF includes one User Info field, where the subfield AID12 is equal to the 12 least significant bits (LSBs) of the Association Identifier (AID) of STA1. The MU-RTS TXS TF further indicates the time domain resources allocated to STA1. STA1 starts using the time domain resources shared by the AP immediately after the AP sends the MU-RTS TXS TF. Specifically, STA1 sets its target reception (RX) address to the association identifier (AID) of G1, STA1 sends a clear-to-send (CTS) frame to G1, STA1 sends a physical layer protocol data unit (PPDU) to G1, and G1 sends an acknowledgement (ACK) frame to STA1.

[0053] To facilitate a better understanding of the embodiments of the present application, another TXOP sharing mechanism related to the present application will be described.

[0054] The TXOP sharing mechanism allows an AP to share a portion of the time of an acquired TXOP with multiple non-AP STAs. As shown in the scene diagram of Figure 2, a TXOP acquired by an AP can be shared so that STA1 and STA2 can use it simultaneously. As shown in Figure 4, during the shared time, the AP allocates RU1 to STA1 for STA1 to transmit non-TB PPDUs to smart glass 1 (G1: Smart glass 1), and allocates RU2 to STA2 for STA2 to transmit non-TB PPDUs to smart glass 2 (G2: Smart glass 2).

[0055] To facilitate a better understanding of the embodiments of the present application, a method for indicating time domain resources allocated to non-AP STAs in the TXOP sharing mechanism related to the present application will be described.

[0056] Figure 5 shows the format of the MU-RTS TXS TF frame, which is: It contains the following fields: Frame Control (occupying 2 bytes), Time Length (occupying 2 bytes), Receiving Address (RA) (occupying 6 bytes), Transmission Address (TA) (occupying 6 bytes), Common Info (occupying 8 or more bytes), User Info list (occupying a variable number of bytes), padding (occupying a variable number of bytes), and Frame Check Sequence (FCS) (occupying 4 bytes).

[0057] Here, the frame control field, the time length field, the RA field, and the TA field form a media access control (MAC) header.

[0058] As shown in Figure 5, the common information field is Trigger Type (occupies 4 bits), uplink length (UL Length) (occupies 12 bits), more trigger frames (TF) (occupies 1 bit), whether carrier sense (CS) is required (occupies 1 bit), uplink bandwidth (BW) (occupies 2 bits), guard interval (GI) and high efficiency long training field (HE-LTF) type (occupies 2 bits), multiple users multiple-in multiple-out (MU-MIMO) HE-LTF mode (occupies 1 bit), number of HE-LTF symbols and intermediate code period (occupies 3 bits), uplink space-time block code (STBC) (occupies 1 bit), low-density parity check (LDPC) It includes the following subfields: check additional symbol segment (occupying 1 bit), AP transmit power (occupying 6 bits), Pre-Forward Error Correction (Pre-FEC) filler roll (occupying 2 bits), Packet Extension (PE) disambiguity (occupying 1 bit), uplink specific reuse (occupying 16 bits), Doppler (occupying 1 bit), uplink High Efficiency-SINGAL field-A2 (HE-SIG-A2) reserved (occupying 9 bits), reserved (occupying 1 bit), and trigger-related common information (occupying a variable number of bits).

[0059] As shown in Figure 5, the User Information List field is It includes the following subfields: AID12 (occupying 12 bits), RU allocation (occupying 8 bits), uplink forward error correction (FEC) coding type (occupying 1 bit), uplink high efficiency modulation and coding scheme (HE-MCS) (occupying 4 bits), uplink dual carrier modulation (DCM) (occupying 1 bit), spatial stream (SS) allocation / random access resource unit (RA-RU) information (occupying 6 bits), uplink target received power (occupying 7 bits), reservation (occupying 1 bit), and trigger-related user information (occupying a variable number of bits).

[0060] Specifically, the method of allocating time to non-AP STAs is as follows.

[0061] Option 1: Use reserved bits in the User Info field in the User Information List field to indicate, for example, 7 reserved bits to indicate (2 7 ) time units, each of which is 128 μs.

[0062] Option 2: Indicated using the UL Length subfield of the Common Info field, for example, a total of 12 reserved bits (2 12 ) time units, each time unit being 4 μs.

[0063] It should be noted that the maximum time duration shared by the above two methods is approximately 16 ms.

[0064] The TXOP sharing mechanism shown in Figure 3 above only supports one STA to share and use a portion of the TXOP time acquired by the AP.

[0065] The TXOP sharing mechanism shown in Figure 4 above proposes that multiple STAs share a portion of the TXOP time acquired by the AP and use it simultaneously, but is designed from the perspective of assigning different RUs (supported in the frequency domain) to multiple non-AP STAs.

[0066] Regarding the method of indicating the time domain resources allocated to non-AP STAs in the TXOP sharing mechanism shown in FIG. 5 above, it only supports allocating time domain resources to one non-AP STA.

[0067] The above technology does not take into account the time-sharing use of the TXOP acquired by the AP by multiple non-AP STAs, and the method of instructing the allocation of time domain resources shared by the AP may not support multiple non-AP STAs.

[0068] Based on the above technical problems, this application proposes a TXOP sharing scheme, in which an AP shares part of the acquired TXOP with multiple pairs of non-AP STAs in a time-sharing manner, and the usage method can be that a non-AP STA sends a non-TB PPDU to its associated AP, or that a non-AP STA sends a non-TB PPDU to another STA.

[0069] Specifically, the AP allocates different time domain resources to multiple non-AP STAs via the MU-RTS TXS TF frame for transmitting non-TB PPDUs. Each non-AP STA synchronously returns a CTS frame to the AP. Each non-AP STA transmits a non-TB PPDU to its associated AP or another STA in the allocated time domain resource. The AP or another STA associated with the non-AP STA returns an ACK to the non-AP STA.

[0070] For example, as shown in Figure 6, the AP shares some or all of the time domain resources of the acquired TXOP with STA1 and STA2, and STA1 and STA2 synchronously return CTS frames to the AP. STA1 transmits PPDU1 to G1 in the allocated time domain resources, and G1 returns an ACK to STA1. STA2 transmits PPDU2 to G2 in the allocated time domain resources, and G2 returns an ACK to STA2.

[0071] The technical solution of the present application will be described in detail below through specific examples.

[0072] FIG. 7 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 7, the wireless communication method 200 may include at least some of the following contents:

[0073] At S210, the AP transmits first information, which is used to share some or all of the time domain resources of the TXOP acquired by the AP with multiple STAs, where the first information is used to indicate at least one of address information of the multiple STAs, length information of the time domain resources corresponding to the multiple STAs, starting time domain positions of the time domain resources corresponding to the multiple STAs, and time frequency domain resources corresponding to the multiple STAs.

[0074] At S220, a first STA receives the first information sent by the AP, where the plurality of STAs includes the first STA.

[0075] In some embodiments, the wireless communication method 200 may include S230.

[0076] At S230, STAx receives the first information sent by the AP, where the plurality of STAs includes STAx, that is, the AP can simultaneously send the first information to the plurality of STAs.

[0077] It should be noted that the first STA may be any STA among the plurality of STAs.

[0078] In an embodiment of the present application, an AP may share some or all of the time domain resources of the TXOP it acquires with multiple STAs, and may specify at least one of the address information of the multiple STAs, the length information of the time domain resources corresponding to the multiple STAs, the start time domain positions of the time domain resources corresponding to the multiple STAs, and the time-frequency domain resources corresponding to the multiple STAs, thereby allowing the multiple STAs to communicate based on the resources shared by the AP, thereby reducing the communication delay of the STAs.

[0079] In some embodiments, the address information for the multiple STAs may include the 12 least significant bits of the AID.

[0080] In some embodiments, the first information is transmitted by a first trigger frame, for example, a multi-user request-to-send transmission opportunity sharing trigger frame (MU-RTS TXS TF). Of course, the first trigger frame may be another type of trigger frame, but this application is not limited thereto.

[0081] In some embodiments, the first trigger frame includes a TXOP sharing mode subfield, and the TXOP sharing mode subfield is set to a non-zero value.

[0082] For example, the TXOP sharing mode subfield is set to 1, 2, or 3.

[0083] In some embodiments, when the first information is used to indicate address information of at least the plurality of STAs, the first trigger frame includes a user information list field, the user information list field includes a plurality of user information fields, each of the plurality of user information fields corresponds to the plurality of STAs, and each user information field of the plurality of user information fields is used to indicate address information of a corresponding STA.

[0084] In some implementations, the address information includes the 12 least significant bits of an associated identifier AID, and a subfield AID12 in each user information field of the plurality of user information fields is used to indicate the 12 least significant bits (LSBs) of the AID of the corresponding STA. For example, the first trigger frame may be MU-RTS TXS TF, and subfield AID12 may be, for example, as shown in FIG. 8.

[0085] It should be noted that the subfield AID12 of the User Information field in FIG. 8 is equal to the 12 LSBs of the AID of the STA.

[0086] In some embodiments, when the first information is used to indicate length information of time domain resources corresponding to at least the multiple STAs, the first trigger frame includes a user information list field, where the user information list field includes multiple user information fields, each corresponding to the multiple STAs, and M reserved bits in each user information field of the multiple user information fields are used to indicate the length of the time domain resource of the corresponding STA, where M is a positive integer.

[0087] For example, the first trigger frame is an MU-RTS TXS TF, and as shown in FIG. 9, B20 to B39 (totaling 20 bits) of the User Info field are reserved bits (or can be redefined), and M bits (7 or 12, not limited here) of these bits (i.e., M reserved bits) can be used (or redefined) as an indication of the length (time duration) of the time domain resource allocated to the corresponding non-AP STA (i.e., as the time duration allocation subfield in FIG. 9).

[0088] In some implementations, the M reserved bits are M can indicate 2 time units, M The time length provided by the M time units is the length of the time domain resource of the corresponding STA specified by the M reserved bits.

[0089] For example, the time unit is 4 μs or 128 μs, and the present application does not limit the specific length of the time unit.

[0090] In some embodiments, when the first information is used to indicate length information of time domain resources corresponding to at least the plurality of STAs, the first trigger frame includes a common information field, wherein an uplink length subfield in the common information field is used to indicate the overall length of the time domain resources corresponding to the plurality of STAs, the length of the time domain resources corresponding to each STA among the plurality of STAs is the same, and each STA among the plurality of STAs determines the length of its corresponding time domain resource from the overall length of the time domain resources based on the order in its user information list field.

[0091] That is, the multiple STAs share the entire length of the time domain resource equally.

[0093] TIFF0007739454000002.tif63170

[0094] In some implementations, if the length of the entire time domain resource includes a SIFS, each STA of the plurality of STAs determines the length of its corresponding time domain resource based on Equation 2:

[0095] In some embodiments, when the first information is used to indicate length information of time domain resources corresponding to at least the plurality of STAs, the first trigger frame includes a common information field, wherein an uplink length subfield in the common information field is used to indicate a time domain resource of a first length, each STA among the plurality of STAs corresponds to the time domain resource of the first length, and each STA among the plurality of STAs determines the length of its corresponding time domain resource from the length of the entire time domain resources based on the order in its user information list field.

[0098] In some embodiments, when the first information is used to indicate length information of time domain resources corresponding to at least the plurality of STAs, the first trigger frame includes a common information field and a user information list field, wherein an uplink length subfield in the common information field is used to indicate a second length of time domain resources, the user information list field includes a plurality of user information fields, the plurality of user information fields respectively corresponding to the plurality of STAs, at least one reserved bit included in each user information field among the plurality of user information fields is used to indicate an offset value of the length of the time domain resources of the corresponding STA, and each STA among the plurality of STAs determines the length of its corresponding time domain resource based on the offset value of the length of the time domain resource corresponding to it and the second length of the time domain resource.

[0099] TIFF0007739454000005.tif64170

[0100] In some embodiments, when the first information is used to indicate a starting time domain position of a time domain resource corresponding to at least the plurality of STAs, the first trigger frame includes a user information list field, the user information list field includes a plurality of user information fields, the plurality of user information fields respectively corresponding to the plurality of STAs, and N reserved bits in each user information field of the plurality of user information fields are used to indicate a starting time domain position of the time domain resource of the corresponding STA, where N is a positive integer.

[0101] For example, the first trigger frame is an MU-RTS TXS TF, and as shown in Figure 10, bits B20 to B39 (totaling 20 bits) of the User Info field are reserved bits (or can be redefined), and M bits (7 or 12, not limited here) of these bits (i.e., the above M reserved bits) can be used (or redefined) as a time duration indication of the time domain resource allocated to the corresponding non-AP STA (i.e., the time duration allocation subfield in Figure 10). Furthermore, N bits (7 or 12, not limited here) of these bits (i.e., the N reserved bits) can be used (or redefined) as a start time domain position indication of the time domain resource allocated to the corresponding non-AP STA (i.e., the start time subfield in Figure 10).

[0102] It should be noted that in the above Fig. 10, the start time of the first non-AP STA may be the time when the transmission of the MU-RTS TXS TF ends, and may be indicated by a reserved bit in the User Info field (or a bit multiplexed with the User Info field). Since the time length allocation subfield indicating the length of the shared time domain resource already occupies M bits in the User Info field, M+N≦20.

[0103] In some implementations, the N reserved bits are N can indicate 2 time units, N The starting time domain positions of the time domain resources obtained by the N time units are the starting time domain positions of the time domain resources of the corresponding STAs specified by the N reserved bits.

[0104] For example, the time unit is 4 μs or 128 μs, and the present application does not limit the specific length of the time unit.

[0105] In some embodiments, the start time domain position of the time domain resource corresponding to each STA among the plurality of STAs is determined based on the order in the user info list of the plurality of STAs, i.e., each STA among the plurality of STAs infers the start time domain position of using the assigned time domain resource based on the order in its user info list.

[0106] In some implementations, the time domain resources corresponding to each STA among the plurality of STAs are assigned based on the order in the user information list of the plurality of STAs, and / or the time domain resources corresponding to the plurality of STAs are contiguous. That is, the AP assigns the length of the time domain resources to each STA among the plurality of STAs sequentially according to the order in the user information list. The lengths of the time domain resources assigned by the AP to the plurality of STAs are contiguous.

[0107] In some implementations, each STA in the plurality of STAs needs to know its order in the User Info List, and each STA in the plurality of STAs needs to know the length of the time domain resources assigned to all STAs before it in the User Info List.

[0108] In some implementations, the first STA determines the starting time domain position of the time domain resource corresponding to the first STA based on the order of the first STA in the user information list and the length information of the time domain resources corresponding to all STAs located before the first STA in the user information list.

[0109] TIFF0007739454000006.tif91170

[0110] In some implementations, the starting time domain position of the time domain resource corresponding to the first STA is the time when the transmission of the first trigger frame (eg, MU-RTS TXS TF) ends.

[0111] In some embodiments, when the first information is used to indicate time-frequency domain resources corresponding to at least the plurality of STAs, respectively, the first trigger frame includes a user information list field, where the user information list field includes a plurality of user information fields, each of the plurality of user information fields corresponding to the plurality of STAs, a time length allocation subfield in each user information field among the plurality of user information fields is used to indicate the time domain resource of the corresponding STA, and a resource unit allocation subfield in each user information field among the plurality of user information fields is used to indicate the frequency domain resource of the corresponding STA.

[0112] In some embodiments, the first STA may transmit a non-trigger-based PPDU (non-TB PPDU) to the AP within the shared time domain resource, or the first STA may transmit a non-trigger-based PPDU (non-TB PPDU) to another STA within the shared time domain resource.

[0113] In some embodiments, if the first STA prematurely terminates its use of the time domain resource shared with it, the first STA releases the time domain resource shared with it. Furthermore, the first STA does not transmit information to the AP indicating that the first STA has released the time domain resource shared with it. That is, the first STA can directly release the time domain resource shared with it without notifying the AP.

[0114] In some embodiments, the AP receives second information transmitted by a first STA among the plurality of STAs, and the second information is used to indicate that the first STA has released the time domain resource shared with the first STA, that is, if the first STA prematurely terminates use of the time domain resource shared with it, the first STA can indicate to the AP that it has already released the shared time domain resource.

[0115] In some implementations, the second information is a TXOP sharing release frame. For example, if the first STA prematurely ends use of the time domain resource shared with it, the first STA can send a TXOP sharing release frame to the AP, and the TXOP sharing release frame may be as shown in Figure 11. When the AP receives the TXOP sharing release frame sent by the first STA, it can know that the first STA has released the time domain resource shared with the first STA.

[0116] In some implementations, the second information is a Contention Free End (CF-End) frame, and when the AP receives the CF-End frame transmitted by the first STA, the AP can know that the first STA has released the time domain resource shared with the first STA.

[0117] In some implementations, the second information is carried by a TXOP Sharing Termination subfield in the Frame Control field of the first PPDU. For example, the More Data subfield in the Frame Control field can be defined as a TXOP Sharing Termination subfield, as shown in FIG. 12.

[0118] Specifically, as shown in FIG. 12, the frame control field further includes: The frame control field may include the following subfields: Protocol Version, Type, Subtype, Target Distribution System (DS) (to DS), Source DS (from DS), More Fragments, Retry, Power Management, Protected Frame, and High-Throughput Control (HTC). That is, the frame control field is a frame control field with an HTC subfield.

[0119] For example, the first STA may set the TXOP sharing end subfield in the frame control field of the first PPDU to 1 to indicate to the AP that it has released the shared time domain resource.

[0120] In some implementations, when the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to the AP within the shared time domain resource, the first PPDU is the last PPDU transmitted by the first STA.

[0121] In some implementations, when the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to another STA within a shared time domain resource, the first PPDU is a PPDU transmitted by the first STA to the AP.

[0122] In some embodiments, the AP and the plurality of STAs do not use the remaining time domain resources shared by the AP to the first STA, i.e., the remaining time domain resources shared by the first STA are idle and unused, and subsequent STAs (i.e., STAs whose starting time domain positions of the corresponding time domain resources are later than the starting time domain positions of the time domain resources corresponding to the first STA) wait until the preset time domain resources of the MU-RTS TXS TF frame arrive, and then continue to use the TXOP time domain resources shared by the AP.

[0123] For example, as shown in Figure 13, the AP shares some or all of the time domain resources of the TXOP it has acquired with STA1 and STA2, and STA1 and STA2 synchronously return CTS frames to the AP. STA1 transmits PPDU1 to G1 in the allocated time domain resources, and G1 returns an ACK to STA1, after which STA1 releases the time domain resources shared with it. STA2 transmits PPDU2 to G2 in the allocated time domain resources, and G2 returns an ACK to STA2. As shown in Figure 13, the remaining time domain resources shared with STA1 are idle and unused.

[0124] In some implementations, after receiving the second information, the AP does not feed back information to the first STA, or after receiving the second information, the AP feeds back an ACK frame to the first STA.

[0125] In some implementations, after transmitting the second information, the first STA does not transmit any frames in the remaining time domain resources shared with it.

[0126] In some embodiments, the AP transmits a frame (e.g., a data frame or a management frame, the frame type is not limited in this application) to at least one STA using the remaining time domain resources shared with the first STA. Subsequent STAs (i.e., STAs whose starting time domain positions of the corresponding time domain resources are later than the starting time domain positions of the time domain resources corresponding to the first STA) wait until the preset time domain resources of the MU-RTS TXS TF frame arrive, and then continue to use the TXOP time domain resources shared by the AP.

[0127] In some implementations, the at least one STA does not include the first STA, or the at least one STA includes the first STA.

[0128] For example, the at least one STA includes the first STA, and the first STA receives the frame transmitted by the AP using the remaining time domain resource shared with the first STA.

[0129] In some implementations, from the time the AP receives the second information until the shared time domain resource allocated to the STA next to the first STA starts, the AP transmits a frame to the at least one STA using the remaining time domain resource shared with the first STA.

[0130] For example, as shown in Figure 14, the AP shares some or all of the time domain resources of the TXOP it has acquired with STA1 and STA2, and STA1 and STA2 synchronously return CTS frames to the AP. STA1 transmits PPDU1 to G1 in the allocated time domain resources, and G1 returns an ACK to STA1, after which STA1 releases the time domain resources shared with it. STA2 transmits PPDU2 to G2 in the allocated time domain resources, and G2 returns an ACK to STA2. As shown in Figure 14, the AP transmits data / PPDU to STA3 using the remaining time domain resources shared with STA1.

[0131] In some implementations, when the AP receives the second information transmitted by the first STA, the AP may begin transmission (e.g., may transmit data or other frames to other STAs associated with it) anywhere from the current time until the shared time domain resource allocated to the next STA begins.

[0132] In some implementations, after transmitting the second information, the first STA does not transmit any frames in the remaining time domain resources shared with it.

[0133] In some embodiments, the AP transmits third information, where the third information is used to indicate to at least one STA to share the remaining time domain resources shared by the first STA, for example, the third information is transmitted via an MU-RTS TXS TF.

[0134] In some implementations, the AP receives the CTS frame transmitted by the at least one STA. For example, when the AP receives the second information transmitted by the first STA, the AP transmits an MU-RTS TXS TF frame to reallocate time domain resources to the at least one STA from the current time to before the start of the time domain resources allocated to the next STA. When the at least one STA receives the MU-RTS TXS TF frame transmitted by the AP, it returns a CTS frame to the AP and then operates according to the time domain resources allocated by the MU-RTS TXS TF frame.

[0135] In some embodiments, the AP transmits third information, where the third information is used to indicate to at least one STA to re-share all time domain resources from the time the second information is received until the end of TXOP sharing, for example, via an MU-RTS TXS TF.

[0136] In some implementations, the AP receives the clear-to-send CTS frame transmitted by the at least one STA. For example, when the AP receives the second information transmitted by the first STA, the AP transmits an MU-RTS TXS TF frame to reallocate all time domain resources from the current time to the end of the TXOP sharing to the at least one STA. When the at least one STA receives the MU-RTS TXS TF frame transmitted by the AP, it transmits a CTS frame back to the AP and then operates according to the time domain resources allocated by the MU-RTS TXS TF frame.

[0137] For example, as shown in FIG. 15, the AP shares some or all of the time domain resources of the TXOP it acquired with STA1 and STA2, and STA1 and STA2 synchronously return CTS frames to the AP. STA1 transmits PPDU1 to G1 in the assigned time domain resources, and G1 returns an ACK to STA1, after which STA1 releases the time domain resources shared with it. STA2 transmits PPDU2 to G2 in the assigned time domain resources, and G2 returns an ACK to STA2. As shown in FIG. 15, the AP transmits an MU-RTS TXS TF frame using the remaining time domain resources shared with STA1. For example, the MU-RTS TXS TF frame reallocates, to at least one STA, the time domain resources from the current time until the start of the time domain resources allocated to the next STA. As another example, the MU-RTS TXS TF frame reallocates, to at least one STA, all the time domain resources from the current time until the end of the TXOP sharing.

[0138] In some embodiments, the AP transmits fourth information, wherein the fourth information is used to indicate that at least one STA among the plurality of STAs will start using the corresponding time domain resource early, and the starting time domain position of the time domain resource corresponding to the at least one STA is later than the starting time domain position of the time domain resource corresponding to the first STA.

[0139] In some implementations, the fourth information is transmitted via a Multiple Users Request-To-Send Transmission Opportunity Sharing Announce (MU-RTS TXSA) frame.

[0140] In some implementations, the MU-RTS TXSA frame is obtained by setting the Guard Interval (GI) and High Efficiency Long Training Field (HE-LTF) mode subfields in a multi-user transmission request trigger frame (MU-RTS TF) to non-zero values, or the MU-RTS TXSA frame is obtained by setting the TXOP sharing mode subfield in the MU-RTS TF to a non-zero value, for example, 3.

[0141] For example, as shown in Figure 16, the AP shares some or all of the time domain resources of the TXOP it has acquired with STA1 and STA2, and STA1 and STA2 synchronously return CTS frames to the AP. STA1 transmits PPDU1 to G1 in the allocated time domain resources, and G1 returns an ACK to STA1, after which STA1 releases the time domain resources shared with it. As shown in Figure 16, the AP transmits an MU-RTS TXSA frame to STA1 using the remaining shared time domain resources, and the MU-RTS TXSA frame instructs STA2 to start using the corresponding time domain resources early. STA2 transmits PPDU2 to G2 in the allocated time domain resources, and G2 returns an ACK to STA2.

[0142] In some implementations, the MU-RTS TXSA frame includes a start time subfield, which is used to indicate a time when the at least one STA starts using the corresponding time domain resource early. For example, the MU-RTS TXSA frame includes a user information field, which may be as shown in Figure 17, where the user information field includes a start time field (occupying j bits), which is used to indicate a time when the at least one STA starts using the corresponding time domain resource early.

[0143] In some implementations, the time at which the at least one STA begins using the corresponding time domain resource early is the time at which transmission of the MU-RTS TXSA frame ends, in which the MU-RTS TXSA frame includes a user information field, which may be as shown in FIG. 18, and which includes only subfield AID12 and reserved subfields.

[0144] In some implementations, the fourth information is transmitted via a second trigger frame, for example, a multi-user request to send transmission opportunity sharing trigger frame (MU-RTS TXS TF).

[0145] In some implementations, the configuration parameters of the length information of the time domain resource corresponding to the at least one STA in the second trigger frame match the configuration parameters in the first trigger frame, and the configuration parameters of the start time domain position of the time domain resource corresponding to the at least one STA in the second trigger frame are set to a time at which the at least one STA starts using the corresponding time domain resource early.

[0146] For example, in the second trigger frame, the length of the time domain resources allocated to the at least one STA is maintained as the value set in the original first trigger frame, and only the start time domain position indication of the time domain resources allocated to the at least one STA in the second trigger frame is modified. After receiving the second trigger frame transmitted by the AP, the at least one STA starts using the allocated time domain resources early according to the start time domain position indication of the allocated time domain resources, and the use time length is indicated by the length of the time domain resources in the first trigger frame.

[0147] In some implementations, the configuration parameter of the length information of the time domain resource corresponding to the at least one STA in the second trigger frame is empty or a reserved bit, and the configuration parameter of the start time domain position of the time domain resource corresponding to the at least one STA in the second trigger frame is set to a time at which the at least one STA starts using the corresponding time domain resource early.

[0148] For example, in the second trigger frame, the length indication of the time domain resource allocated to the at least one STA is set to empty or a reserved bit, and only the start time domain position indication of the time domain resource allocated to the at least one STA is modified in the second trigger frame. After receiving the second trigger frame sent by the AP, the at least one STA starts using the allocated time domain resource early according to the start time domain position indication of the allocated time domain resource in the frame, and the use time length is the time length allocated by the previous first trigger frame.

[0149] Therefore, in an embodiment of the present application, an AP can share some or all of the time domain resources of the TXOP it acquires with multiple STAs for time-division use, and a corresponding resource sharing mechanism and frame structure are provided, thereby reducing the communication time delay of the STAs.

[0150] Furthermore, the embodiments of the present application propose a scheme to indicate the length of time domain resources allocated to multiple STAs, allowing the AP to flexibly allocate time domain resources to non-AP STAs participating in sharing the TXOP acquired, and in the future, different (length) resources can be allocated to non-AP STAs with different Quality of Service (QoS) requirements, thereby improving user QoS.

[0151] Furthermore, the embodiments of the present application propose a scheme to indicate the starting time domain position of time domain resources allocated to multiple STAs, and allocate time domain resources at forward positions to non-AP STAs that are sensitive to time delay, thereby reducing the communication time delay of the non-AP STAs that are sensitive to time delay.

[0152] Furthermore, the embodiments of the present application propose a reuse scheme for the remaining time domain resources after a non-AP STA prematurely terminates the use of the time domain resources shared by the AP, which not only improves resource utilization but also further reduces the communication time delay of the time delay-sensitive non-AP STAs by allocating the remaining time domain resources to the time delay-sensitive non-AP STAs.

[0153] Furthermore, the embodiments of the present application propose that multiple STAs share the TXOP acquired by the AP in the time domain, and by combining this scheme with the TXOP acquired by the AP in the frequency domain, the number of non-AP STAs that can participate in the sharing of the TXOP acquired by the AP can be further increased, and the overall network delay can be further reduced.

[0154] FIG. 19 is a schematic interaction diagram of a wireless communication method 300 according to an embodiment of the present application. As shown in FIG. 19, the wireless communication method 300 may include at least some of the following contents:

[0155] In S310, the AP decides to share some or all of the time domain resources of the acquired TXOP among multiple STAs.

[0156] At S320, the AP transmits first information to a first STA among the plurality of STAs, the first information being used to indicate at least one of address information of the first STA, length information of the time domain resource corresponding to the first STA, starting time domain position of the time domain resource corresponding to the first STA, and time frequency domain resource corresponding to the first STA.

[0157] At S330, the first STA receives the first information transmitted by the AP.

[0158] It should be noted that the first STA may be any STA among the plurality of STAs.

[0159] In some embodiments, the first information is transmitted by a first trigger frame, for example, a multi-user request-to-send transmission opportunity sharing trigger frame (MU-RTS TXS TF). Of course, the first trigger frame may be another type of trigger frame, but this application is not limited thereto.

[0160] In some embodiments, after the time domain resource shared with the first STA is terminated, the AP transmits second information to a next STA of the plurality of STAs, the second information comprising: It is used to indicate at least one of the address information of the next STA, the length information of the time domain resource corresponding to the next STA, the starting time domain position of the time domain resource corresponding to the next STA, and the time frequency domain resource corresponding to the next STA.

[0161] In some embodiments, the second information is transmitted via a second trigger frame, for example, a multi-user request-to-send transmission opportunity sharing trigger frame (MU-RTS TXS TF). Of course, the second trigger frame may be another type of trigger frame, but this application is not limited thereto.

[0162] In an embodiment of the present application, the AP decides to share some or all of the time domain resources of the acquired TXOP among multiple STAs, and the AP uses an MU-RTS TXS TF frame each time to share and allocate some of the time domain resources to one of the multiple STAs, and after the STA has finished using the time domain resources, the AP uses the MU-RTS TXS TF frame again to allocate some of the time domain resources to the next STA. In this way, some or all of the time domain resources of the TXOP acquired by the AP can be shared among multiple non-AP STAs in a time-division manner.

[0163] For example, as shown in Figure 20, the AP decides to share some or all of the time domain resources of the TXOP it has acquired with STA1 and STA2. The AP sends an MU-RTS TXS TF frame to STA1 to share some of the time domain resources with STA1, STA1 returns a CTS frame to the AP, STA1 transmits PPDU1 to G1 in the allocated time domain resources, and G1 returns an ACK to STA1. After the time domain resources shared with STA1 are used up, the AP sends an MU-RTS TXS TF frame to STA2 to share some of the time domain resources with STA2, STA2 returns a CTS frame to the AP, STA2 transmits PPDU2 to G2 in the allocated time domain resources, and G2 returns an ACK to STA2. As shown in Figure 20, the AP allocates the shared time domain resources to only one non-AP STA at a time, and after use is finished, the AP allocates the shared time domain resources to the next non-AP STA.

[0164] In some embodiments, when the first information is used to indicate at least address information of the first STA, the first trigger frame includes a user information list field, the user information list field includes a user information field, and the user information field is used to indicate address information of the first STA.

[0165] In some embodiments, the address information includes the 12 least significant bits of an AID, and subfield AID12 in the user information field is used to indicate the 12 least significant bits of the AID of the first STA.

[0166] It should be noted that when the first information is used to indicate at least the address information of the first STA, for a specific description of the address information of the first STA, reference may be made to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0167] In some embodiments, when the first information is used to indicate at least length information of a time domain resource corresponding to the first STA, the first trigger frame includes a user information list field, where the user information list field includes a user information field, and M reserved bits in the user information field are used to indicate the length of the time domain resource of the first STA, where M is a positive integer.

[0168] It should be noted that when the first information is used to indicate at least the length information of the time domain resource corresponding to the first STA, for a specific description of the length of the time domain resource of the first STA, reference may be made to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0169] In some embodiments, when the first information is used to indicate a starting time domain position of a time domain resource corresponding to at least the first STA, the first trigger frame includes a user information list field, the user information list field includes a user information field, and N reserved bits in the user information field are used to indicate a starting time domain position of the time domain resource of the first STA, where N is a positive integer.

[0170] It should be noted that when the first information is used to indicate the starting time domain position of the time domain resource corresponding to at least the first STA, for a specific description of the starting time domain position of the time domain resource of the first STA, reference may be made to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0171] In some embodiments, when the first information is used to indicate at least time-frequency domain resources corresponding to the first STA, the first trigger frame includes a user information list field, where the user information list field includes a user information field, a time length allocation subfield in the user information field is used to indicate the time domain resources of the first STA, and a resource unit allocation subfield in the user information field is used to indicate the frequency domain resources of the first STA.

[0172] It should be noted that when the first information is used to indicate at least the time-frequency domain resource corresponding to the first STA, for a specific description of the time-frequency domain resource of the first STA, reference may be made to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0173] In some embodiments, the first trigger frame includes a TXOP sharing mode subfield, and the TXOP sharing mode subfield is set to a non-zero value.

[0174] In some embodiments, the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to the AP within the shared time domain resource, or the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to another STA within the shared time domain resource.

[0175] In some embodiments, if the first STA prematurely terminates its use of the time domain resource shared with it, the first STA releases the time domain resource shared with it. Furthermore, the first STA does not transmit information to the AP indicating that the first STA has released the time domain resource shared with it. That is, the first STA can directly release the time domain resource shared with it without notifying the AP. For a detailed description, please refer to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0176] In some embodiments, the AP receives the third information transmitted by the first STA, and the third information is used to indicate that the first STA has released the time domain resource shared with the first STA. That is, if the first STA prematurely ends its use of the time domain resource shared with it, the first STA can indicate to the AP that it has already released the shared time domain resource.

[0177] In some embodiments, the third information is a TXOP shared release frame, or the third information is a contention-free end frame. For a detailed description, please refer to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0178] In some embodiments, the third information is carried by a TXOP Shared End subfield in the Frame Control field of the first PPDU.

[0179] In some implementations, if the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to the AP within the shared time domain resource, the first PPDU is the last PPDU transmitted by the first STA.

[0180] In some implementations, when the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to another STA within a shared time domain resource, the first PPDU is a PPDU transmitted by the first STA to the AP.

[0181] In some embodiments, the AP and the plurality of STAs do not use the remaining time domain resources shared by the AP to the first STA, that is, the remaining time domain resources shared by the first STA are idle and not used. For a detailed description, please refer to the relevant description in the above wireless communication method 200, and the description will not be repeated here.

[0182] In some implementations, after transmitting the third information, the first STA does not transmit any frames in the remaining time domain resources shared with it.

[0183] In some embodiments, after receiving the third information, the AP does not feed back information to the first STA, or after receiving the third information, the AP feeds back an ACK frame to the first STA.

[0184] In some embodiments, the AP transmits a frame to at least one STA using the remaining time domain resources shared with the first STA. For specific descriptions, please refer to the relevant descriptions in the above wireless communication method 200, and the description will not be repeated here.

[0185] In some embodiments, the at least one STA does not include the first STA, or the at least one STA includes the first STA.

[0186] For example, the at least one STA includes the first STA, and the first STA receives the frame transmitted by the AP using the remaining time domain resource shared with the first STA.

[0187] In some embodiments, the AP transmits fourth information, where the fourth information is used to indicate that the remaining time domain resources shared with the first STA are to be shared with at least one STA. Furthermore, the AP receives a CTS frame transmitted by the at least one STA. For specific descriptions, please refer to the relevant descriptions in the above wireless communication method 200, and they will not be repeated here.

[0188] For example, the fourth information is transmitted via a multi-user request to send transmission opportunity sharing trigger frame (MU-RTS TXS TF).

[0189] Therefore, in an embodiment of the present application, an AP can share some or all of the time domain resources of the TXOP it acquires with multiple STAs for time-division use, and a corresponding resource sharing mechanism and frame structure are provided, thereby reducing the communication time delay of the STAs.

[0190] Furthermore, the embodiments of the present application propose a scheme for indicating the length of time domain resources allocated to multiple STAs, allowing the AP to flexibly allocate time domain resources to non-AP STAs participating in sharing the TXOP acquired, and in the future, different (length) resources can be allocated to non-AP STAs with different QoS requirements, thereby improving user QoS.

[0191] Furthermore, the embodiments of the present application propose a scheme to indicate the starting time domain position of time domain resources allocated to multiple STAs, and allocate time domain resources at forward positions to non-AP STAs that are sensitive to time delay, thereby reducing the communication time delay of the non-AP STAs that are sensitive to time delay.

[0192] Furthermore, the embodiments of the present application propose a reuse scheme for the remaining time domain resources after a non-AP STA prematurely terminates the use of the time domain resources shared by the AP, which not only improves resource utilization but also further reduces the communication time delay of the time delay-sensitive non-AP STAs by allocating the remaining time domain resources to the time delay-sensitive non-AP STAs.

[0193] Furthermore, the embodiments of the present application propose that multiple STAs share the TXOP acquired by the AP in the time domain, and by combining this scheme with the TXOP acquired by the AP in the frequency domain, the number of non-AP STAs that can participate in the sharing of the TXOP acquired by the AP can be further increased, and the overall network delay can be further reduced.

[0194] FIG. 21 is a schematic interaction diagram of a wireless communication method 400 according to an embodiment of the present application. As shown in FIG. 21, the wireless communication method 400 may include at least some of the following contents:

[0195] At S410, the AP obtains the remaining time domain resources that it shares with a first STA of the multiple STAs.

[0196] In an embodiment of the present application, an AP can share some or all of the time domain resources of the TXOP it has acquired with multiple STAs, and if a first STA prematurely finishes using the time domain resources shared with it, the first STA releases the time domain resources shared with the first STA.

[0197] In some embodiments, the first STA does not re-use the time domain resource shared with the first STA.

[0198] In some embodiments, the first STA does not send information to the AP to indicate that the first STA has released the time domain resource shared with the first STA, that is, the first STA can directly release the time domain resource shared with the first STA without notifying the AP.

[0199] In some embodiments, the AP transmits frames to at least one STA using the remaining time domain resources shared with the first STA.

[0200] In some embodiments, the at least one STA does not include the first STA, or the at least one STA includes the first STA.

[0201] In some embodiments, the AP transmits third information, wherein the third information is used to indicate that the remaining time domain resources shared with the first STA will be re-shared with at least one STA, or the third information is used to indicate that all time domain resources from a first time to the end of the transmission opportunity TXOP sharing will be re-shared with at least one STA, and the first time is the time to obtain the remaining time domain resources shared with the first STA.

[0202] In some embodiments, the AP receives a clear-to-send CTS frame transmitted by the at least one STA.

[0203] In some embodiments, the third information is transmitted via a multi-user request to send transmission opportunity sharing trigger frame (MU-RTS TXS TF).

[0204] In some embodiments, the AP transmits fourth information, wherein the fourth information is used to indicate that at least one STA among the plurality of STAs will start using the corresponding time domain resource early, and the starting time domain position of the time domain resource corresponding to the at least one STA is later than the starting time domain position of the time domain resource corresponding to the first STA.

[0205] In some embodiments, the fourth information is transmitted via a Multi-User Request to Send Transmission Opportunity Share Announcement (MU-RTS TXSA) frame.

[0206] In some embodiments, the MU-RTS TXSA frame is obtained by setting the GI and HE-LTF mode subfields in a multi-user transmission request trigger frame (MU-RTS TF) to non-zero values, or the MU-RTS TXSA frame is obtained by setting the TXOP shared mode subfield in the MU-RTS TF to a non-zero value.

[0207] In some embodiments, the non-zero value is three.

[0208] In some embodiments, the MU-RTS TXSA frame includes a start time subfield, which is used to indicate the time at which the at least one STA should begin using the corresponding time domain resource early.

[0209] In some embodiments, the time at which the at least one STA begins using the corresponding time domain resource early is the time at which transmission of the MU-RTS TXSA frame ends.

[0210] In some embodiments, the fourth information is transmitted via a second trigger frame.

[0211] In some embodiments, a configuration parameter of the length information of the time domain resource corresponding to the at least one STA in the second trigger frame is consistent with a configuration parameter in the first trigger frame, and a configuration parameter of the start time domain position of the time domain resource corresponding to the at least one STA in the second trigger frame is set to a time at which the at least one STA starts using the corresponding time domain resource early.

[0212] In some embodiments, a configuration parameter of the length information of the time domain resource corresponding to the at least one STA in the second trigger frame is empty or a reserved bit, and a configuration parameter of the start time domain position of the time domain resource corresponding to the at least one STA in the second trigger frame is set to a time at which the at least one STA starts using the corresponding time domain resource early.

[0213] In some embodiments, the second trigger frame is a multi-user request to send transmission opportunity sharing trigger frame (MU-RTS TXS TF).

[0214] In some embodiments, the AP and the plurality of STAs do not use the remaining time domain resources shared by the AP to the first STA.

[0215] In some embodiments, the AP receives second information transmitted by the first STA, and the second information is used to indicate that the first STA has released the time domain resource shared with the first STA. That is, if the first STA prematurely terminates its use of the time domain resource shared with it, the first STA can indicate to the AP that it has already released the shared time domain resource.

[0216] In some implementations, the second information is a TXOP sharing release frame. For example, if the first STA prematurely ends use of the time domain resource shared with it, the first STA can send a TXOP sharing release frame to the AP, and the TXOP sharing release frame may be as shown in Figure 11. When the AP receives the TXOP sharing release frame sent by the first STA, it can know that the first STA has released the time domain resource shared with the first STA.

[0217] In some implementations, the second information is a Contention Free End (CF-End) frame, and when the AP receives the CF-End frame transmitted by the first STA, the AP can know that the first STA has released the time domain resource shared with the first STA.

[0218] In some embodiments, the second information is carried by a TXOP Shared End subfield in a Frame Control field of a first PPDU transmitted by the first STA.

[0219] In some implementations, the second information is carried by a TXOP Sharing Termination subfield in the Frame Control field of the first PPDU. For example, the More Data subfield in the Frame Control field can be defined as a TXOP Sharing Termination subfield, as shown in FIG. 12.

[0220] For example, the first STA may set the TXOP sharing end subfield in the frame control field of the first PPDU to 1 to indicate to the AP that it has released the shared time domain resource.

[0221] In some implementations, when the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to the AP within the shared time domain resource, the first PPDU is the last PPDU transmitted by the first STA.

[0222] In some implementations, when the first STA transmits a non-trigger-based PPDU (non-TB PPDU) to another STA within a shared time domain resource, the first PPDU is a PPDU transmitted by the first STA to the AP.

[0223] In some embodiments, the AP does not feed back information to the first STA after receiving the second information; or After receiving the second information, the AP feeds back an ACK frame to the first STA.

[0224] It should be noted that for the explanation of terms in the embodiments of the present application, reference can be made to the relevant explanation in the above wireless communication method 200, and for the sake of brevity, the explanation will not be repeated here.

[0225] Therefore, the embodiments of the present application propose a reuse scheme for the remaining time domain resources after a non-AP STA prematurely terminates the use of the time domain resources shared by the AP, which not only improves resource utilization but also further reduces the communication time delay of the time delay-sensitive non-AP STAs by allocating the remaining time domain resources to the time delay-sensitive non-AP STAs.
