Description

TECHNICAL FIELD

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

[0002] The current Wi-Fi technology is researched in the range of: 320MHz bandwidth transmission, multiple frequency band aggregation and coordination, etc., and it is expected to improve the rate and throughput by at least four times compared with the existing standard, and the main application scenarios are video transmission, AR(Augmented Reality), VR(Virtual Reality), etc.

[0003] The multiple frequency band aggregation and coordination refers to the communication between devices in 2.4GHz, 5GHz and 6GHz frequency bands at the same time, and a new MAC(Media Access Control) mechanism needs to be defined to manage the communication between devices in multiple frequency bands at the same time. In addition, it is also expected that the multiple frequency band aggregation and coordination can support low latency transmission.

[0004] The current multiple frequency band aggregation and system technology will support a maximum bandwidth of 320MHz(160MHz+160MHz), and in addition, it may also support 240MHz(160MHz+80MHz) and other bandwidths.

[0005] In the data transmission phase, in order to improve the utilization efficiency of the spectrum, the format of the multi-TID(Traffic Identifier) confirmation message frame can be used, however, according to the existing communication mechanism, only one TID corresponding BA(Block Ack) can be negotiated each time, so multiple negotiations are needed for the BA of multiple TIDs, which leads to low spectrum efficiency and increases the latency.

[0031] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 is a diagram showing an example of BA negotiation.

[0033] Referring to Figure 1 In (a) setup phase, an initiator and a receiver initiate a session through a handshake of an ADDBA Request frame and an ADDBA Response frame. The ADDBA Request frame and the ADDBA Response frame can be management frames, and can exist in the form of an Action frame. The management frames (ADDBA Request frame and ADDBA Response frame) are required to be acknowledged by an Ack (Acknowledgment). As shown in Figure 1 The procedure of setting up a session is that the initiator transmits the ADDBA Request frame to the receiver; the receiver returns an Ack indicating that the ADDBA Request frame is received, and then the receiver transmits the ADDBA Response frame in response to the ADDBA Request frame; and the initiator returns an Ack indicating that the ADDBA Response frame is received.

[0034] After the session connection is set up, in (b) data transmission & block acknowledgement phase, for example, during a transmission opportunity (TXOP), the initiator can continuously transmit a plurality of data frames, for example, Quality of Service (QoS) data frames (i.e., QoS Data frames), and after the transmission of the data frames is completed, a block acknowledgement request frame (Block Ack Req) is transmitted; and the receiver feeds back a block acknowledgement (BA) about the plurality of data frames. Figure 1

[0035] ​After the Block Ack acknowledgement is completed, the session can be closed. Specifically, in the (c) tear down phase, the initiator can send a DELBA Request frame, and then the responder returns an Ack.

[0036] In the (a) setup phase, the format of the ADDBA Request frame sent by the initiator to the responder can be as shown in Table 1 below.

[0037] Table 1. ADDBA Request frame Action field format

[0038] Order Information 1 Category 2 Block Ack Action 3 Dialog Token 4 Block Ack Parameter Set 5 Block Ack Timeout Value 6 Block Ack Starting Sequence Control 7 GCR Group Address element (optional) 8 Multi-band (optional) 9 TCLAS (optional) 10 ADDBA Extension (optional)

[0039] Referring to Table 1, the ADDBA Request frame can include a Category field, a Block Ack Action field, a Dialog Token field, a Block Ack Parameter Set field, a Block Ack Timeout Value field, and a Block Ack Starting Sequence Control field. In addition, optional, the ADDBA Request frame can also include a Groupcast with Retries (GCR) Group Address Element field, a Multi-band field, a TCLAS field, and an ADDBA Extension field.

[0040] The definition of the Block Ack Parameter Set field of Table 1 can be as shown in Table 2 below.

[0041] Table 2. Block Ack Parameter Set fixed field

[0042]

[0043] In Table 2, MSDU can indicate MAC Service Data Unit. BA policy can be used to define whether Ack is immediate feedback or delayed feedback. TID can indicate communication identification. Buffer Size can indicate the number of buffers available for one specific TID. For example, when A-MSDU Supported field indicated by Block Ack Parameter Set field transmitted by a station is equal to 0, the number of bytes each buffer can hold is equal to the maximum value of MSDU. When A-MSDU Supported field is equal to 1 indicated by a station, the number of bytes each buffer can hold is equal to the maximum value of A-MSDU supported by the station.

[0044] In (b) Data Transfer & Block Ack phase, for Multi-TID Block Ack, Block Ack Info field can be defined as shown in Table 3 below.

[0045] Table 3. Block Ack Info field (Multi-TID Block Ack)

[0046]

[0047] Repeat for each TID

[0048] In (b) Data Transfer & Block Ack phase, for Multi-TID Block AckReq, Block Ack Request (BAR) Info field can be defined as shown in Table 4 below.

[0049] Table 4. Block Ack Request (BAR) Info field (Multi-TID Block AckReq)

[0050]

[0051] Repeat for each TID

[0052] Per TID Info subfield can be defined as shown in Table 5 below.

[0053] Table 5. Per TID Info subfield

[0054]

[0055] Definition of Block Ack Starting Sequence Control subfield can be shown in Table 6 below.

[0056] Table 6. Block Ack Starting Sequence Control subfield

[0057]

[0058] Since the Block ACK parameter set field contained in the ADDBA request frame contains only one TID subfield (see Table 2), that is, only one TID corresponding to the BA can be negotiated at a time, however, there is a multi-TID BA format in the BAR information field and the BA information field (see Table 3 and Table 4), so multiple negotiations are required for the multi-TID BA, which is not high in spectral efficiency and increases the latency.

[0059] Figure 2 is a flowchart illustrating a communication method according to an example embodiment of the present disclosure.

[0060] Figure 2 The flowchart of can be an operation performed by an initiator, and correspondingly, the operation of will be described below. Figure 3 may be an operation performed by a receiver. For example, the initiator can be a station (STA), and correspondingly, the receiver can be an access point (AP); or the initiator can be an AP, and correspondingly, the receiver can be a STA. The AP can include software applications and / or circuits to enable other types of nodes in a wireless network to communicate with the outside and inside of the wireless network through the AP. In some examples, the AP can be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity) chip, as an example. As an example, the station STA can include, but is not limited to: a cellular phone, a smart phone, a wearable device, a computer, a personal digital assistant (PDA), a personal communication system (PCS) device, a personal information manager (PIM), a personal navigation device (PND), a global positioning system, a multimedia device, an Internet of Things (IoT) device, etc.

[0061] Referring to Figure 2In step 210, a first message frame can be determined, wherein the first message frame comprises parameter information related to at least one communication identifier (TID). According to an embodiment of the present disclosure, the TID can correspond to different upper layer services and QoS requirements. In an embodiment of the present disclosure, there can be various ways to determine the first message frame, for example, the initiator can generate the first message frame according to at least one of the following: network conditions, load conditions, hardware capabilities of the transmitting / receiving device, service type, relevant protocol provisions; the present embodiment of the present disclosure does not make specific limitations thereto. In an embodiment of the present disclosure, the initiator can also obtain the first message frame from an external device, and the present embodiment of the present disclosure does not make specific limitations thereto.

[0062] For example, the first message frame can be an ADDBA request frame or an ADDBA response frame. The included parameter information can be, for example, an enhanced TID BA parameter set subfield, which can be defined as shown in Table 7 below.

[0063] Table 7. Enhanced TID BA parameter set subfield

[0064]

[0065] According to an embodiment of the present disclosure, the parameter information can comprise more than one communication identifier, such as TID1, TID2, etc. in Table 7. The more than one communication identifier (TID1, TID2, etc.) can correspond to different upper layer services and QoS requirements. In the case of supporting general services, each communication identifier (TID1, TID2, etc.) can have four bits as shown in Table 2, or in the case of supporting other low latency services, the TID can have one more bit, i.e., five bits. However, this is only exemplary, and the number of bits for each TID is not limited thereto.

[0066] According to an embodiment of the present disclosure, the parameter information can further comprise a block acknowledgement policy parameter corresponding to each of the more than one communication identifier, such as BA policy 1, BA policy 2, etc. in Table 7. In an embodiment, when the block acknowledgement policy parameter is set to 1, it is used to indicate immediate block acknowledgement (Immediate Block Ack), and when the block acknowledgement policy parameter is set to 0, it is used to indicate delayed block acknowledgement (Delayed Block Ack). It will be understood that the setting value of the block acknowledgement policy parameter is exemplary, and other values can also be used for identification.

[0067] According to an embodiment of the present disclosure, the parameter information can further comprise a buffer size parameter corresponding to each of the more than one communication identifier, such as buffer size 1, buffer size 2, etc. in Table 7.

[0068] According to an embodiment of the present disclosure, the parameter information can further include information of MSDUs corresponding to more than one communication identifier respectively, for example, support A-MSDU 1, support A-MSDU 2, etc. in Table 7.

[0069] In one embodiment, the length of the buffer size parameter is related to the supported MSDU type. For example, the MSDU type is at least one of a first type of MSDU or A-MSDU and a second type of MSDU or A-MSDU. That is, the length of the buffer size parameter can have different number of bits according to the MSDU or A-MSDU. For example, the first type of MSDU or A-MSDU can be 1024 MSDU or A-MSDU, and the second type of MSDU or A-MSDU can be 4096 MSDU or A-MSDU. If the communication system supports a maximum of 1024 MSDU or A-MSDU, the length of the buffer size parameter can be 10 bits, and if the communication system supports 4096 MSDU or A-MSDU, the length of the buffer size parameter can be 12 bits. However, this is only exemplary, and the MSDU or A-MSDU can also have other types, and the length of the buffer size parameter is not limited thereto.

[0070] It can be understood that each element shown in Tables 1 to 7 exists independently, and these elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in Tables 1 to 7. Therefore, those skilled in the art can understand that the value of each element in the table of the present disclosure is an independent embodiment.

[0071] According to an embodiment of the present disclosure, the parameter information as shown in Table 7 can be encapsulated in the first message frame, for example, can be encapsulated in the corresponding order (for example, order 11) of the ADDBA request frame or the ADDBA response frame.

[0072] In step 220, the first message frame can be transmitted. For example, the first message frame can be transmitted under the first connection. Wherein, the first connection is any connection supported by the initiator, the TID can be mapped to any connection supported by the initiator, and the initiator can be a device supporting multi-connection communication (STR (simultaneous Tx&Rx: support simultaneous transmission and reception) or Non-STR (support simultaneous transmission or reception)), EMLMR (enhanced multi-link multi-radio) device, EMLSR (enhanced multi-link single-radio) device.

[0073] Figure 3 is a flowchart illustrating another communication method according to an example embodiment of the present disclosure. Figure 3 The flowchart of FIG. 10 can be operations performed at the receiver, i.e., corresponding to the operations of the initiator shown in FIG. 9. Figure 2 The flowchart of FIG. 10 can be operations performed at the receiver, i.e., corresponding to the operations of the initiator shown in FIG. 9.

[0074] Referring to FIG. 10, Figure 3 In step 310, a first message frame can be received, wherein the first message frame can include parameter information related to at least one communication identification. In step 320, a communication operation can be performed based on the first message frame. For example, a plurality of TID BAs can be negotiated at once in step 320 based on the parameter information in step 310.

[0075] According to an embodiment, the parameter information can include: more than one communication identification, a block acknowledgement policy parameter corresponding to each communication identification, a buffer size parameter corresponding to each of the communication identifications, etc.

[0076] According to an embodiment, the length of the buffer size parameter can be related to the supported MSDU type. For example, the MSDU type can be at least one of a first type of MSDU or A-MSDU and a second type of MSDU or A-MSDU.

[0077] According to an embodiment of the present disclosure, the parameter information can be encapsulated in the first message frame, for example, can be encapsulated in the corresponding order (e.g., order 11) of the ADDBA request frame or the ADDBA response frame.

[0078] It will be understood that Figure 3 The parameter information in FIG. 10 can be similar to the description of Figure 2 and Table 7, and repetitive descriptions are omitted herein for the sake of brevity.

[0079] In embodiments of the present disclosure, the Block Ack Parameter Set field can be redefined to support the multi-TID BA scenario. For example, a Multi-TID BA Parameter Set subfield format can be defined, which can have the format shown in Table 7 above. In this case, the TID subfield can be four bits, or can be five bits if other low latency traffic is supported. The Block Ack Policy parameter can be set to 1 for Immediate Block Ack, or set to 0 for Delayed Block Ack. In addition, the Buffer Size parameter subfield can be 10 bits if a maximum of 1024 MSDUs or A-MSDUs are supported, or can be 12 bits if 4096 MSDUs or A-MSDUs are supported. In addition, the parameter information can be encapsulated in the order 11 of the ADDBA request or ADDBA response frame.
