Detailed Description
It should be understood that the numbers "first" and "second" in the embodiments of the present application are used for distinguishing similar objects, and are not necessarily used for describing a specific order or sequence order, and should not be construed as limiting the embodiments of the present application in any way.
The "and/or" mentioned in the embodiments of the present application describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
First, an application scenario and a part of vocabulary related to the embodiments of the present application will be described.
Fig. 1a is a schematic view of a scene provided in an embodiment of the present application. Referring to fig. 1a, a first device performs multi-link transmission with a second device, where the first device and the second device may both be WIFI devices, for example, the first device is an Access Point (AP), the second device is a Station (STA), and so on.
In multilink transmission, information may need to be transmitted between two links. As illustrated in fig. 1b, information is transmitted between the access point and the station via the link Ch1 and the link Ch2, and within the access point or the station, the information is transmitted via the physical layer: PHY1 and PHY2, which may then be connected at two lower Media Access Control (MAC) layers: exchange between LMAC1 and LMAC 2; alternatively, by the higher MAC layer: and (6) MAC exchange.
The inventors have found that for some applications or situations, information from other links may be ambiguous.
For example:
scene one
Referring to fig. 2, an access point and a station transmit aggregate (Aggregation) data with sequence numbers SN1, SN2, … …, and SN8 through a link Ch1, and transmit aggregate data with sequence numbers SN9, SN10, … …, and SN16 through a link Ch2, and a data receiver in the access point or the station normally transmits a Block acknowledgement frame (Block ACK, BA) to a data transmitter through a link corresponding to each aggregate data. As illustrated in fig. 2, if the data sender does not successfully receive the BA transmitted through link Ch1 (hereinafter, it is collectively referred to as reward information) and receives the BA transmitted through link Ch2, where the BA transmitted through link Ch2 includes BA information that should be transmitted by link Ch1, and the BA transmitted through link Ch2 includes 16 bits {1,1,1,1,1,0,0, 1,1,1,1,1,1,1,1}, where a value "0" or "1" indicates whether the aggregated data whose corresponding sequence numbers are SN1, SN2, … …, and SN16 are successfully transmitted, at this time, the data sender understands the aggregated data whose sequence numbers are SN6, SN7, and SN8 that there are the following cases:
1. aggregated data with sequence numbers SN6, SN7, and SN8 all failed to transmit.
2. The link Ch2 is not ready for BA information related to aggregated data with sequence numbers SN6, SN7, and SN 8.
Scene two
Referring to fig. 3, an access point and a station transmit aggregate data with sequence numbers SN1, SN2, … … and SN8 through a link Ch1, and transmit aggregate data with sequence numbers SN9, SN10, … … and SN16 through a link Ch2, wherein a data receiver in the access point or the station transmits a BA corresponding to the aggregate data with sequence numbers SN1, SN2, SN … … and SN16 to a data sender through a link, where the link transmitting the BA is exemplified by the link Ch2, the BA transmitted through the link Ch2 includes 16 bits {1,1,1,1,1,1,1, 0,0,1,1,1,1,1,1, 1}, where a value "0" or "1" indicates whether the aggregate data with the corresponding sequence numbers SN1, SN2, … … and SN16 are successfully transmitted, respectively, and the data receiver transmits the BA through a link 2 after receiving bar (chr 2). At this time, as above, the understanding by the data sender of the aggregated data with sequence numbers SN6, SN7, and SN8 has the following:
1. aggregated data with sequence numbers of SN6, SN7, and SN8 all failed to transmit.
2. The link Ch2 is not ready for BA information related to aggregated data with sequence numbers SN6, SN7, and SN 8.
Based on the above problem, embodiments of the present application provide an information processing method, an information processing apparatus, and a storage medium, which are applied to multilink transmission, where the multilink includes a first link and a second link, so as to avoid the above ambiguity, so that an understanding of information from other links is clear in the multilink transmission process of a device. It should be clear that, the number of the first link and the second link is not limited in the embodiments of the present application.
Fig. 4 is a flowchart of an information processing method according to an embodiment of the present application. The present embodiment provides an information processing method that can be executed by an information processing apparatus mentioned later, which can be implemented by any software and/or hardware. The information processing device may be specifically a WIFI device, such as an AP or STA; alternatively, the information processing device is integrated in the WIFI device.
Referring to fig. 4, the method of the present embodiment includes:
s101, the first equipment receives the packet.
The packet is sent by the second device through the first link, and the packet includes first information including report information indicating a transmission result of the second link.
In this embodiment, the first device is a data sending side corresponding to the data to be transmitted, and the second device is a data receiving side corresponding to the data to be transmitted. Specifically, the first device sends data to the second device through the first link and the second link at the same time, and the second device sends packets to the first device through the first link after receiving all the data. Illustratively, the packet may be embodied as the BA mentioned above.
Optionally, the reward information may include: and the reward information is used for indicating whether the data transmitted by the second link is transmitted successfully.
S102, the first device determines whether the report information is valid according to the packet and the first duration of the second device.
Wherein the first time length is used to characterize a longest time length for the second device to communicate information in the two links. The first duration may also be referred to as a "maximum two-link information transfer duration (mclid)", which is understood by those skilled in the art, and the embodiments of the present application are not limited to this nomenclature.
For MCLIDT, there are several possible definitions of it:
defining one, the MCLIDT is unique for different devices, i.e. the MCLIDT is the same for all devices. Under this definition, there are two more cases:
case one, all devices set MCLIDT.
In case two, the device may choose whether to set MCLIDT. The data transceiver and the data transceiver can interact in advance to set MCLIDT.
Defining two, presetting a plurality of values, for different devices, MCLIDT is relatively optional, and it can select the MCLIDT to be satisfied, that is, the MCLIDT corresponding to all the devices may be different. Under the definition, both data transceivers need to interact with their satisfied MCLIDTs in advance.
It can be understood that, this step determines whether the report information is valid or not based on the packet received by the first device, that is, by taking into account the transmission duration of the information in the second device, so as to avoid the uncertainty and erroneous determination caused by the situation that the first link is not ready to include the report information related to other links of the second link, so that the first device has a clear understanding of the information from other links in the multi-link transmission process.
In this embodiment, a first device receives a packet, where the packet is sent by a second device through a first link, the packet includes first information, and the first information includes report information indicating a transmission result of a second link; and then, the first device determines whether the report information is valid according to the packet and a first time length of the second device, wherein the first time length is used for representing the longest time length for the second device to transmit information in the two links. In the embodiment of the application, when determining whether the report information is valid, the packet received by the first device and the first duration of the second device are considered comprehensively, so that uncertainty and misjudgment caused by the situation that the first link is not ready to include the report information related to other links of the second link can be avoided, and the first device can clearly understand the information from other links in the multi-link transmission process.
Based on the foregoing embodiment, the S102, determining, by the first device, whether the report information is valid according to the packet and the first duration of the second device, may include: the first equipment determines a target time according to the reference time point and the first time length of the packet; if the sending time of the first data transmitted through the second link is earlier than the target time, the first device determines that the return information about the first data in the return information is valid; or, if the sending time of the first data transmitted through the second link is later than the target time, the first device determines that the report back information about the first data in the report back information is invalid.
Optionally, with reference to the time point, any one or more of the following may be used:
the first equipment receives the starting time of the package;
the starting time of the second equipment for sending the package;
a time point separated from the starting time of the second device for sending the packet by a preset interval;
and so on.
The value of the preset interval can be set according to historical experience or actual requirements.
It should be understood that the first time duration corresponding to different reference time points is also different.
Still taking the example shown in fig. 2 or fig. 3 as an example, the first link is Ch2, the second link is Ch1, the packet is BA, the reference time point is the starting time of the first device for receiving the packet, when the first duration of the second device is T3, and the BA transmitted through the link Ch2 includes the first information: {1,1,1,1,1,0,0,0,1,1,1,1, 1} time, where the first 8 bits {1,1,1,1,1,0,0,0} are return information indicating a transmission result of the second link, the first device determines that the return information of the first data of the sequence numbers SN1, SN2, … …, SN8 is valid; when the first duration of the second device is T2, the first device determines that the report back information of the first data with serial numbers SN1, SN2, … …, and SN6 is valid, and the report back information of the first data with serial numbers SN7 and SN8 is invalid; when the first duration of the second device is T1, the first device determines that the report back information of the first data with the serial numbers SN1, SN2, … …, and SN5 is valid, and the report back information of the first data with the serial numbers SN6, SN7, and SN8 is invalid.
Referring to several definitions of MCLIDT as described above, in one possible implementation, before the packet is received by the first device at S101, the method may further include: the first device determines a first duration of the second device according to the preset value.
Alternatively, before the first device receives the packet S101, the method may further include: and the first equipment receives second information sent by the second equipment and determines the first time length according to the second information. Wherein the second information comprises information indicating the first duration. For the signaling or message carrying the second information, the embodiment of the present application is not limited, and specifically, the signaling or message may be a signaling or message already existing in an existing standard, or may also be a newly defined signaling or message, for example, in an embodiment, in an Association (Association) process, information for indicating the first duration may be exchanged via an Association Request (Association Request) and an Association Response (Association Response).
The embodiment aims to enable the first device to determine a value of the first device before using the first duration, and specifically, the value can be obtained according to a preset value or obtained through interaction with the second device. The interaction process of the first device and the second device with respect to the first duration occurs during the association establishment between the first device and the second device, that is, during the initial establishment of the multilink.
As an alternative embodiment, after the step S102, the first device determines whether the report information is valid according to the packet and the first duration of the second device, the method may further include: if the report information is valid, the first device determines whether the data transmitted through the second link is successfully transmitted according to the report information. Taking fig. 2 as an example, the transmission Sequence corresponding to each Sequence Number (SN) in the BA has a corresponding bit, if the bit is 1, the corresponding data transmission is successful, if the bit is 0, the corresponding data transmission is not successful or not yet transmitted, and in the multi-link system, it is possible that information corresponding to other links is not yet transmitted, in this example, SN1, SN2, … …, and SN5 corresponding to the bit being 1 can determine that the transmission is successful, and SN6, SN7, and SN8 corresponding to the bit being 0 have various possibilities. When the first duration of the second device is T3, the first device may determine that the reward information of the first data with sequence numbers SN6, SN7, and SN8 is valid, the reward information of the first data with sequence numbers SN6, SN7, and SN8 is {0,0,0}, and the first device determines that the transmission of the first data with sequence numbers SN6, SN7, and SN8 fails.
Corresponding to the technical scheme in the embodiment, the embodiment of the application also provides a replacement scheme.
Fig. 5 is a flowchart of an information processing method according to another embodiment of the present application. The present embodiment provides an information processing method that can be executed by an information processing apparatus mentioned later, which can be implemented by any software and/or hardware. The information processing device may be specifically a WIFI device, such as an AP or STA; alternatively, the information processing device is integrated in the WIFI device.
Referring to fig. 5, the method of the present embodiment includes:
s201, the first device receives the packet.
The packet is sent by the second device through the first link, and includes first information and second information, where the first information includes report information used for indicating a transmission result of the second link, and the second information is used for indicating whether the report information is valid. It should be clear that this second information is different from the second information in the above-described embodiment.
S202, the first equipment determines whether the return information is effective or not according to the second information.
This embodiment differs from the above embodiment in that: this embodiment adds new information, i.e., second information, to the packet to indicate whether the reported information associated with the second link transmission result is valid. Other descriptions can refer to the above embodiments, and are not repeated herein.
Optionally, the second information may include N bits, where N is an integer greater than or equal to 1, and a value of the N bits is used to indicate whether the reward information is valid. For example, a bit value of "1" is used to indicate that the report information is valid, and a bit value of "0" is used to indicate that the report information is invalid; or, a bit value of "0" is used to indicate that the report information is valid, a bit value of "1" is used to indicate that the report information is invalid, and so on.
Further, after the step S202, the first device determines whether the reward information is valid according to the second information, the method may further include: if the report information is valid, the first device determines whether the data transmitted through the second link is successfully transmitted according to the report information.
In one possible embodiment, the transmission sequence corresponding to each SN in a new BA structure is changed from one corresponding bit to 2 corresponding bits, if the two bits are 01, the corresponding data transmission is successful, if the two bits are 10, the corresponding data transmission is unsuccessful, if the two bits are 00, the corresponding data transmission is not yet transmitted, and if the two bits are 11, the corresponding information of other links of the corresponding data is not yet transmitted. Or, one bit of the double bits represents whether the corresponding sequence number is successfully transmitted, and the other bit represents whether the corresponding sequence number is valid. The information that one bit is additionally added to each serial number is the second information.
In another possible embodiment, the transmission sequence corresponding to each SN in the new BA structure has a corresponding bit, if the bit is 1, the corresponding data transmission is successful, and if the bit is 0, the corresponding data transmission is not successful or has not been transmitted, or information corresponding to other links in the multi-link system has not been transmitted, and additionally, an indication of information from other links is added. For example, in the previous example, the reported information from the other links SN1, SN2, … …, and SN8 is {1,1,1,1, 0,0,0}, and if the additional indication information of the other links is {1,1,1,1,1,1, 1}, the reported information of SN1, SN2, … …, and SN8 is all valid, that is, it is determined that the data transmission with the sequence numbers SN6, SN7, and SN8 fails. If the additional indication information of other links is {1,1,1,1,1,1}, the reporting information of the SN1, the SN2, … …, and the SN6 is valid, that is, it is determined that the data transmission with the SN6 fails, and the data transmission results of the SN7 and the SN8 are still unknown. The additional indication information of the other links is the second information.
Fig. 6 is a schematic structural diagram of an information processing apparatus according to an embodiment of the present application. As shown in fig. 6, the information processing apparatus 60 provided in the present embodiment includes a receiving module 61 and a processing module 62. Wherein:
the receiving module 61 is configured to receive a packet. The packet is sent by the second device through the first link, and the packet includes first information including report information indicating a transmission result of the second link.
The processing module 62 is configured to determine whether the report information is valid according to the packet received by the receiving module 61 and the first duration of the second device.
