Cache data information sending, cache data information receiving apparatus and method

Abstract

A method for transmitting cached data information includes: determining an uplink frame in a first connection among multiple connections, wherein the uplink frame includes at least cached data information for other connections among the multiple connections; and transmitting the uplink frame to an access point via the first connection. This allows the access point to receive cached data information for other connections during communication with a station via the first connection. Thus, before communicating with the station via the other connection, the access point can determine, based on the received cached data information, the amount of data to be transmitted on the other connection, and further determine the communication resources to be allocated to the station for communication via the other connection. Subsequently, when communicating with the station via the other connection, the determined communication resources can be promptly allocated to the station, avoiding the problem of inaccurate communication resource allocation caused by allocating communication resources for the other connection before determining the amount of data to be transmitted on the other connection.

Description

[0001] The present disclosure relates to the field of communication technology, and in particular to a method for sending cached data information, a method for receiving cached data information, a cached data information sending device, a cached data information receiving device, an electronic device, and a computer-readable storage medium. Background Art

[0002] Multiple connections (multi-link) can exist between a station (STA) and an access point (AP). For a non-simultaneously transmit and receive (Non-STR) station with multiple connections, while the station is performing uplink transmission on one connection, it cannot perform uplink transmission on other connections, and the other connections do not perform channel sensing. This period is called a blindness period for the other connections. Only after the terminal completes communication on one connection can it perform uplink transmission on other connections. Summary of the Invention

[0003] In view of this, the embodiments of the present disclosure propose a cache data information sending method, a cache data information receiving method, a cache data information sending device, a cache data information receiving device, an electronic device and a computer-readable storage medium to solve the technical problems in the related art.

[0004] According to a first aspect of an embodiment of the present disclosure, a method for sending cached data information is provided, which is applicable to a station having multiple connections with an access point. The method includes:

[0005] Determining an uplink frame in a first connection of the multiple connections, wherein the uplink frame at least includes buffered data information of other connections in the multiple connections;

[0006] The uplink frame is sent to the access point through the first connection.

[0007] According to a second aspect of an embodiment of the present disclosure, a method for receiving cached data information is provided, which is applicable to an access point, where multiple connections exist between the access point and a station. The method includes:

[0008] An uplink frame is received on a first connection among the multiple connections, wherein the uplink frame at least includes buffered data information of other connections among the multiple connections.

[0009] According to a third aspect of an embodiment of the present disclosure, a buffered data information sending device is provided, applicable to a station, where multiple connections exist between the station and an access point, the device comprising:

[0011] An uplink sending module is configured to send the uplink frame to the access point through the first connection.

[0012] According to a fourth aspect of an embodiment of the present disclosure, a cached data information receiving device is provided, which is applicable to an access point, where multiple connections exist between the access point and a station, and the device includes:

[0013] The uplink receiving module is configured to receive an uplink frame on a first connection among the multiple connections, wherein the uplink frame at least includes buffered data information of other connections among the multiple connections.

[0014] According to a fifth aspect of the embodiments of the present disclosure, an electronic device is provided, including:

[0015] processor;

[0016] a memory for storing processor-executable instructions;

[0017] The processor is configured to execute the above-mentioned method for sending cache data information and / or method for receiving cache data information.

[0018] According to a sixth aspect of an embodiment of the present disclosure, a computer-readable storage medium is proposed, on which a computer program is stored.

[0019] According to an embodiment of the present disclosure, an access point can receive cached data information of other connections during communication with a station via a first connection. Thus, before communicating with the station via the other connection, the access point can determine, based on the received cached data information, how much data to be sent on the other connection, and further determine the communication resources that need to be allocated to the station for communication on the other connection.

[0020] When communicating with the site through other connections later, the determined communication resources can be promptly allocated to the site, avoiding the problem of inaccurate configuration of communication resources caused by configuring communication resources for other connections when the amount of data to be sent on other connections has not yet been determined.

[0021] In addition, in the related art, only the cached data information of the first connection can be sent to the access point through the first connection. However, according to the embodiment of the present disclosure, the cached data information of other connections can be sent to the access point through the first connection, which expands the function of the first connection and improves the utilization of the frequency.

[0040] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0041] During communication between a station and an access point, the station may send buffer data information to the access point to inform the access point of the amount of data the station has to send, so that the access point can determine how much data the station has to send and allocate communication resources for the station.

[0042] For example, for a multi-connected non-simultaneous transmitting and receiving station, since the station is using the first connection to communicate with the access point, the station can determine how much data is to be sent on the first connection, and accordingly generate cached data and send it to the station via the first connection to inform the access point how much data the station has to be sent on the first connection.

[0043] In this case, since the station needs to wait until the communication on the first connection is completed before using the second connection to communicate with the access point, it needs to wait until the communication on the first connection is completed before using the second connection to generate cached data information based on the data to be sent on the second connection, and then send the cached data information of the second connection to the access point through the second connection.

[0044] This means that the station can send cached data information to the access point only when it is communicating with the access point using the second connection. When the station communicates with the access point using the second connection, the access point needs to configure communication resources for the station. However, when the cached data information of the second connection is not received, it is difficult for the access point to accurately configure communication resources for the station.

[0045] Figure 1 This is a schematic flow chart illustrating a method for sending cached data information according to an embodiment of the present disclosure. The method for sending cached data information illustrated in this embodiment can be applied to sites, including but not limited to electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The site can communicate with an access point, including but not limited to electronic devices such as routers and terminals. In one embodiment, the access point can be an access point applicable to the method for receiving cached data information described in any subsequent embodiment.

[0046] In one embodiment, there are multiple connections between the station and the access point, and the station can communicate with the access point through one or more of the multiple connections.

[0047] like Figure 1 As shown, the method for sending cached data information may include the following steps:

[0048] In step S101, an uplink frame is determined in a first connection of the multiple connections, wherein the uplink frame at least includes buffered data information of other connections in the multiple connections;

[0049] In step S102, the uplink frame is sent to the access point through the first connection.

[0050] In one embodiment, the station may determine the uplink frame in the first connection, for example, generate the uplink frame in the process of communicating with the access point using the first connection.

[0051] The uplink frame may include buffered data information of other connections in the multiple connections, and the uplink frame may be sent to the access point via the first connection, thereby sending the buffered data information of other connections in the uplink frame to the access point.

[0052] Accordingly, the access point can receive cached data information of other connections during the process of communicating with the station via the first connection, so that before communicating with the station via the other connection, it can determine how much data to be sent on the other connection based on the received cached data information, and further determine the communication resources that need to be allocated to the station for communication on the other connection.

[0053] When communicating with the site through other connections later, the determined communication resources can be promptly allocated to the site, avoiding the problem of inaccurate configuration of communication resources caused by configuring communication resources for other connections when the amount of data to be sent on other connections has not yet been determined.

[0054] In addition, in related technologies, only cached data information of the first connection can be sent to the access point through the first connection. However, according to this embodiment, cached data information of other connections can be sent to the access point through the first connection, which expands the function of the first connection and improves frequency utilization.

[0055] It should be noted that the above-mentioned first connection and other connections do not refer to a specific connection, but rather multiple different connections. The first connection is the connection currently being used by the site to communicate with the access point, and the other connections are connections not currently being used by the site to communicate with the access point. Once the site uses other connections to communicate with the access point, the other connections currently being used may be referred to as first connections, and the first connections previously used may be referred to as other connections.

[0056] In one embodiment, the first connection and the other connection are in a non-simultaneous sending and receiving state, that is, when the terminal uses the first connection to communicate with the access point, the other connections are in a deaf or power saving (Power Save, PS) state, and the station does not use the other connections to communicate with the access point, nor does it use the other connections for channel sensing.

[0057] In this case, the station cannot communicate with the access point using other connections when communicating with the access point using the first connection. Therefore, this embodiment can be applied to the first connection and other connections in a non-simultaneous transmitting and receiving state.

[0058] Furthermore, this embodiment is also applicable when the first connection and the other connection transition from a non-simultaneous transmission and reception state to a simultaneous transmission and reception state, that is, when transitioning from a Non-STR state to a STR state. Although simultaneous communication is possible on the first connection and the other connection after the transition, communication on the other connection is still not possible during the communication process using the first connection before the transition. Therefore, this embodiment can still be used to send cached data information of the other connection on the first connection before, during, or after the transition.

[0059] In one embodiment, the buffered data information is located in a Medium Access Control (MAC) frame header of the uplink frame, for example, in an A-control field of the MAC frame header.

[0060] In one embodiment, the cached data information includes an identifier of each of the other connections and information corresponding to the amount of data to be sent on each of the other connections.

[0061] By carrying the identifiers of other connections and the information corresponding to the amount of data to be sent on the other connections in the cached data information, the access point can determine, based on the identifiers, which identifiers the cached data information is for, and determine, based on the information corresponding to the amount of data to be sent on the other connections, the amount of data to be sent on the other connections, thereby configuring appropriate communication resources for the other connections.

[0062] For example, the station communicates with the access point using the first connection. There are at least two other connections, identified as LinkID2 and LinkID3. The information corresponding to the amount of data to be sent on the connection LinkID2 is buffer size2, and the information corresponding to the amount of data to be sent on the connection LinkID3 is buffer size3. Then, the buffered data information may be as shown in Table 1:

[0063] LinkID2 buffer size2 LinkID3 buffer size 3 ……

[0064] Table 1

[0065] Based on the cached data information, the access point can determine that the information corresponding to the data volume of the data to be sent on the connection LinkID2 is buffer size2, and thus determine the data volume of the data to be sent on the connection LinkID2 based on buffer size2, and then determine the communication resources allocated to the connection LinkID2 based on the data volume of the data to be sent on the connection LinkID2. After the station completes communication using the first connection, when using the connection LinkID2 for communication, the determined communication resources can be allocated to the connection LinkID2, so that the station can use the communication resources to communicate with the access point on the connection LinkID2.

[0066] Correspondingly, based on the cached data information, the access point can also determine that the information corresponding to the data volume of the data to be sent on connection LinkID3 is buffer size3, thereby determining the data volume of the data to be sent on connection LinkID3 based on buffer size3, and then determining the communication resources allocated to connection LinkID3 based on the data volume of the data to be sent on connection LinkID3. After the station completes communication using the first connection, when using connection LinkID3 to communicate, the determined communication resources can be allocated to connection LinkID3, so that the station can use the communication resources to communicate with the access point on connection LinkID3.

[0067] In one embodiment, the cached data information further includes a traffic ID (TID) corresponding to each of the other connections.

[0068] Different connections may have different transmission identifiers, which may represent information such as the service, data type, and quality of service corresponding to the connection. The following mainly uses the example of how the transmission identifier may represent the quality of service. For connections with different transmission identifiers, the access point may allocate different resources to the connection, for example, different resource allocation periods. In this embodiment, the transmission identifiers of other connections may be carried in the cached data information and sent to the access point. For example, the cached data information may be as shown in Table 2:

[0069] LinkID2 buffer size2 TID2 LinkID3 buffer size 3 TID3 ……

[0070] Table 2

[0071] Based on the cached data information, the access point can determine that the transmission identifier of the connection LinkID2 is TID2. Based on TID2, the quality of service required for the data to be sent on the connection LinkID2 can be determined as QoS2. Therefore, the data volume of the data to be sent on the connection LinkID2 can be determined according to the quality of service QoS2 and buffer size2.

[0072] Accordingly, based on the cached data information, the access point can determine that the transmission identifier of connection LinkID3 is TID3, and based on TID3, it can determine that the quality of service required for the data to be sent on connection LinkID3 is QoS3, thereby determining the data volume of the data to be sent on connection LinkID3 according to the quality of service QoS3 and buffer size3.

[0073] Figure 2 FIG. 1 is a schematic flow chart of another method for sending cached data information according to an embodiment of the present disclosure. Figure 2 As shown, in some embodiments of the present disclosure, sending the uplink frame to the access point through the first connection includes:

[0074] In step S201, a transmission identifier corresponding to each of the other connections is determined;

[0075] In step S202, the buffered data information of other connections corresponding to the largest transmission identifier is sent to the access point via the first connection.

[0076] In one embodiment, if the station cannot send the cached data information of all other connections to the access point on the first connection, for example due to insufficient resources, the station may send the cached data information of other connections corresponding to the largest transmission identifier to the access point.

[0077] Since the transmission identifier can be associated with the quality of service of the data to be sent on the connection, generally speaking, the larger the transmission identifier, the higher the quality of service required for the data to be sent, and the higher the quality of service, the lower the communication delay allowed. Therefore, the cached data information of other connections corresponding to the larger transmission identifier can be sent preferentially to ensure that the access point can preferentially receive the cached data information of these other connections, thereby allocating resources to these other connections in a timely manner, ensuring that the data to be sent on these other connections can be sent in a timely manner.

[0078] For example, among the transmission identifiers corresponding to all other connections, at least one transmission identifier greater than a preset threshold is determined, and then the buffered data information of the other connections corresponding to the determined transmission identifier is sent to the access point.

[0079] Furthermore, the largest transmission identifier may be determined among the transmission identifiers corresponding to all other connections, and then the buffered data information of other connections corresponding to the largest transmission identifier may be sent to the access point.

[0080] Figure 3 FIG. 1 is a schematic flow chart of another method for sending cached data information according to an embodiment of the present disclosure. Figure 3 As shown, in some embodiments of the present disclosure, the method further includes:

[0081] In step S301, in response to completion of communication through the first connection, receiving resource configuration information sent by the access point through the other connection;

[0082] In step S302, communication resources for communicating with the access point on the other connection are determined according to the resource configuration information.

[0083] In one embodiment, since the station sends cached data information of other connections to the access point when communicating with the access point through the first connection, the access point can determine the resources allocated to other connections based on the received cached data information before the station completes communication through the first connection, and generate resource configuration information accordingly.

[0084] After the station completes communication with the access point via the first connection, when selecting another connection to communicate with the access point, the access point can immediately send the determined resource configuration information to the station via the other connection, so that the station can promptly determine the communication resources for sending information to the station on the other connection based on the resource configuration information, and then communicate with the station on the determined communication resources.

[0085] Figure 4 FIG. 1 is a schematic flow chart of another method for sending cached data information according to an embodiment of the present disclosure. Figure 4As shown, in some embodiments of the present disclosure, determining the resource for sending information to the site on the other connection according to the resource configuration information includes:

[0086] In step S401, when the communication bandwidth of the access point is fully occupied by the station, it is determined to occupy the communication bandwidth and send information to the access point on the other connection, wherein the resource configuration information includes a trigger frame.

[0087] In one embodiment, the communication bandwidth of the access point can be fully occupied by the station. That is, the station has exclusive use of the communication bandwidth of the access point. Then, all resources on the communication bandwidth of the access point can be used arbitrarily by the station. Therefore, it is not necessary to configure specific resource units (RUs) for the station. Only a simple trigger frame needs to be sent to instruct the station to send information to the access point on the communication bandwidth. The specific resource units of the communication bandwidth on which the information is sent can be determined by the station as needed.

[0088] Figure 5 FIG. 1 is a schematic flow chart of another method for sending cached data information according to an embodiment of the present disclosure. Figure 5 As shown, in some embodiments of the present disclosure, determining the resource for sending information to the site on the other connection according to the resource configuration information includes:

[0089] In step S501, when the communication bandwidth of the access point is not fully occupied by the station, it is determined to occupy the resource unit indicated by the resource allocation message frame and send information to the access point on the other connection, wherein the resource configuration information includes the resource allocation message frame.

[0090] In one embodiment, when the communication bandwidth of the access point is not fully occupied by the station, the resources on the communication bandwidth of the access point can be used arbitrarily by the station. Therefore, a resource allocation message frame can be configured for the station to indicate a specific resource unit to the station, and then the station sends information to the access point on the indicated resource unit.

[0091] Figure 6 FIG. 1 is a schematic flow chart of another method for sending cached data information according to an embodiment of the present disclosure. Figure 6 As shown, in some embodiments of the present disclosure, the method further includes:

[0092] In step S601, a medium synchronization delay timer (MediumSync Delay timer) corresponding to the other connection is started or restarted.

[0093] In one embodiment, when communication through the first connection is completed, the medium synchronization delay timer corresponding to other connections can be started or restarted, which means that the timing value of the medium synchronization delay timer corresponding to other connections is set to 0, so as to prepare to wake up other connections, and then after the timer expires, other connections can be woken up, and then other connections can be used to communicate with the access point.

[0094] Figure 7 This is a schematic flow chart illustrating a method for receiving cached data information according to an embodiment of the present disclosure. The cached data information transmission method illustrated in this embodiment can be applied to an access point, which can communicate with a station, including but not limited to electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The access point includes but is not limited to electronic devices such as routers and terminals. In one embodiment, the terminal can be a station to which the cached data information transmission method described in any of the above embodiments is applicable.

[0095] In one embodiment, there are multiple connections between the station and the access point, and the station can communicate with the access point through one or more of the multiple connections.

[0096] like Figure 7 As shown, the cache data information receiving method may include the following steps:

[0097] In step S701, an uplink frame is received on a first connection among the multiple connections, wherein the uplink frame at least includes buffered data information of other connections among the multiple connections.

[0098] In one embodiment, the station may determine the uplink frame in the first connection, for example, generate the uplink frame in the process of communicating with the access point using the first connection.

[0099] The uplink frame may include buffered data information of other connections in the multiple connections, and the uplink frame may be sent to the access point via the first connection, thereby sending the buffered data information of other connections in the uplink frame to the access point.

[0100] Accordingly, the access point can receive cached data information of other connections during the process of communicating with the station via the first connection, so that before communicating with the station via the other connection, it can determine how much data to be sent on the other connection based on the received cached data information, and further determine the communication resources that need to be allocated to the station for communication on the other connection.

[0101] Subsequently, in one embodiment, the station may determine an uplink frame in the first connection, for example, generating the uplink frame in a process of communicating with the access point using the first connection.

[0102] The uplink frame may include buffered data information of other connections in the multiple connections, and the uplink frame may be sent to the access point via the first connection, thereby sending the buffered data information of other connections in the uplink frame to the access point.

[0103] Accordingly, the access point can receive cached data information of other connections during the process of communicating with the station via the first connection, so that before communicating with the station via the other connection, it can determine how much data to be sent on the other connection based on the received cached data information, and further determine the communication resources that need to be allocated to the station for communication on the other connection.

[0104] When communicating with the site through other connections later, the determined communication resources can be promptly allocated to the site, avoiding the problem of inaccurate configuration of communication resources caused by configuring communication resources for other connections when the amount of data to be sent on other connections has not yet been determined.

[0105] Furthermore, while related technologies only transmit cached data information for the first connection to the access point via the first connection, this embodiment allows for the transmission of cached data information for other connections to the access point via the first connection, expanding the functionality of the first connection and improving frequency utilization. When communicating with a station via other connections, the determined communication resources can be promptly allocated to the station, avoiding the problem of inaccurate resource allocation caused by allocating communication resources for other connections before determining the amount of data to be sent on the other connections.

[0106] In addition, in related technologies, only cached data information of the first connection can be sent to the access point through the first connection. However, according to this embodiment, cached data information of other connections can be sent to the access point through the first connection, which expands the function of the first connection and improves frequency utilization.

[0107] In one embodiment, the first connection and the other connection are in a non-simultaneous sending and receiving state, that is, when the terminal uses the first connection to communicate with the access point, the other connections are in a deaf or power saving (Power Save, PS) state, and the station does not use the other connections to communicate with the access point, nor does it use the other connections for channel sensing.

[0108] In this case, the station cannot communicate with the access point using other connections when communicating with the access point using the first connection. Therefore, this embodiment can be applied to the first connection and other connections in a non-simultaneous transmitting and receiving state.

[0109] Furthermore, this embodiment is also applicable when the first connection and the other connection transition from a non-simultaneous transmission and reception state to a simultaneous transmission and reception state, that is, when transitioning from a Non-STR state to a STR state. Although simultaneous communication is possible on the first connection and the other connection after the transition, communication on the other connection is still not possible during the communication process using the first connection before the transition. Therefore, this embodiment can still be used to send cached data information of the other connection on the first connection before, during, or after the transition.

[0110] In one embodiment, the buffered data information is located in the media access control frame header of the uplink frame, for example, in the A-control field of the MAC frame header.

[0111] In one embodiment, the cached data information includes an identifier of each of the other connections and information corresponding to the amount of data to be sent on each of the other connections.

[0112] By carrying the identifiers of other connections and the information corresponding to the amount of data to be sent on the other connections in the cached data information, the access point can determine, based on the identifiers, which identifiers the cached data information is for, and determine, based on the information corresponding to the amount of data to be sent on the other connections, the amount of data to be sent on the other connections, thereby configuring appropriate communication resources for the other connections.

[0113] For example, the station uses the first connection to communicate with the access point, and there are at least two other connections, which are identified as LinkID2 and LinkID3 respectively. The information corresponding to the data volume of the data to be sent on the connection LinkID2 is buffer size2, and the information corresponding to the data volume of the data to be sent on the connection LinkID3 is buffer size3. Then the cached data information can be as shown in Table 1.

[0114] Based on the cached data information, the access point can determine that the information corresponding to the data volume of the data to be sent on the connection LinkID2 is buffer size2, and thus determine the data volume of the data to be sent on the connection LinkID2 based on buffer size2, and then determine the communication resources allocated to the connection LinkID2 based on the data volume of the data to be sent on the connection LinkID2. After the station completes communication using the first connection, when using the connection LinkID2 for communication, the determined communication resources can be allocated to the connection LinkID2, so that the station can use the communication resources to communicate with the access point on the connection LinkID2.

[0115] Correspondingly, based on the cached data information, the access point can also determine that the information corresponding to the data volume of the data to be sent on connection LinkID3 is buffer size3, thereby determining the data volume of the data to be sent on connection LinkID3 based on buffer size3, and then determining the communication resources allocated to connection LinkID3 based on the data volume of the data to be sent on connection LinkID3. After the station completes communication using the first connection, when using connection LinkID3 to communicate, the determined communication resources can be allocated to connection LinkID3, so that the station can use the communication resources to communicate with the access point on connection LinkID3.

[0116] In one embodiment, the cache data information further includes a transmission identifier corresponding to the other connection.

[0117] Different connections can have different transmission identifiers, which can represent information such as the service, data type, and quality of service corresponding to the connection. The following example illustrates how the transmission identifier can represent quality of service. For connections with different transmission identifiers, the access point can allocate different resources to the connection, for example, with different resource allocation periods. In this embodiment, the transmission identifiers of other connections can be included in cached data information sent to the access point. For example, the cached data information can be as shown in Table 2.

[0118] Based on the cached data information, the access point can determine that the transmission identifier of the connection LinkID2 is TID2. Based on TID2, the quality of service required for the data to be sent on the connection LinkID2 can be determined as QoS2. Therefore, the data volume of the data to be sent on the connection LinkID2 can be determined according to the quality of service QoS2 and buffer size2.

[0119] Accordingly, based on the cached data information, the access point can determine that the transmission identifier of connection LinkID3 is TID3, and based on TID3, it can determine that the quality of service required for the data to be sent on connection LinkID3 is QoS3, thereby determining the data volume of the data to be sent on connection LinkID3 according to the quality of service QoS3 and buffer size3.

[0120] Figure 8 FIG. 1 is a schematic flow chart of another method for receiving cached data information according to an embodiment of the present disclosure. Figure 8 As shown, the method further includes:

[0121] In step S801, resource configuration information is generated according to the cached data information, wherein the resource configuration information is used to indicate the communication resources used by the station to communicate with the access point on the other connection.

[0122] In one embodiment, the access point can determine how much data to be sent on other connections based on the cached data information, and then determine the communication resources that need to be allocated to the station for communication on other connections, and generate resource configuration information based on the determined communication resources, and then send the resource configuration information to the station.

[0123] The resource configuration information may be sent to the site through the first connection, or may be sent to the site through other connections.

[0124] Figure 9 FIG. 1 is a schematic flow chart of another method for receiving cached data information according to an embodiment of the present disclosure. Figure 9 As shown, generating resource configuration information according to the cache data information includes:

[0125] In step S901, the resource configuration information is generated according to the cached data information and the modulation and coding scheme (MCS) of the most recent communication with the station through the other connection.

[0126] In one embodiment, after receiving cached data information of other connections, the access point can query the modulation and coding strategy used in the most recent communication with the station via the other connection. The modulation and coding strategy can affect the communication rate, and the modulation and coding strategy used by the access point and the station for the next communication using the other connection is likely to be the same as the modulation and coding strategy used in the most recent communication. Therefore, communication resources can be configured for the other connection not only based on the cached data information, but also based on the modulation and coding strategy.

[0127] For example, for two other connections link1 and link2 with the same amount of data to be sent, the modulation and coding strategy used by the access point and the station in the most recent communication on link1 is MCS1, and the modulation and coding strategy used by the access point and the station in the most recent communication on link2 is MCS2. MCS1 corresponds to a higher communication rate, and MCS2 corresponds to a lower communication rate. In this case, fewer communication resources can be allocated to link1, and more communication resources can be allocated to link2.

[0128] Figure 10 FIG. 1 is a schematic flow chart of another method for receiving cached data information according to an embodiment of the present disclosure. Figure 10 As shown, the method further includes:

[0129] In step S1001, in response to completion of communication through the first connection, the resource configuration information is sent to the site through the other connection.

[0130] In one embodiment, since the station sends cached data information of other connections to the access point when communicating with the access point through the first connection, the access point can determine the resources allocated to other connections based on the received cached data information before the station completes communication through the first connection, and generate resource configuration information accordingly.

[0131] After the station completes communication with the access point via the first connection, when selecting another connection to communicate with the access point, the access point can immediately send the determined resource configuration information to the station via the other connection, so that the station can promptly determine the communication resources for sending information to the station on the other connection based on the resource configuration information, and then communicate with the station on the determined communication resources.

[0132] In one embodiment, when the communication bandwidth of the access point is fully occupied by the station, the resource configuration information includes a trigger frame, and the trigger frame is used to instruct the access point to occupy the communication bandwidth to send information to the access point on the other connection.

[0133] In one embodiment, the communication bandwidth of the access point can be fully occupied by the station, that is, the station exclusively occupies the communication bandwidth of the access point. Then, all resources on the communication bandwidth of the access point can be used arbitrarily by the station. Therefore, it is not necessary to configure specific resource units for the station. Only a simple trigger frame needs to be sent to instruct the station to send information to the access point on the communication bandwidth. The specific resource units of the communication bandwidth on which the information is sent can be determined by the station as needed.

[0134] In one embodiment, when the communication bandwidth of the access point is not fully occupied by the station, the resource configuration information includes a resource allocation message frame, and the resource allocation message frame is used to instruct the access point to occupy the resource unit indicated by the resource allocation message frame to send information to the access point on the other connection.

[0135] In one embodiment, when the communication bandwidth of the access point is not fully occupied by the station, the resources on the communication bandwidth of the access point can be used arbitrarily by the station. Therefore, a resource allocation message frame can be configured for the station to indicate a specific resource unit to the station, and then the station sends information to the access point on the indicated resource unit.
