Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a data processing method, device, system, storage medium and product. BACKGROUND

[0002] Currently, in order to save energy, the user equipment as a data receiver automatically wakes up from the starting position of each discontinuous cycle, is in an active window period, and the active duration of the active window period is determined by a discontinuous reception duration timer. In the active window period, the operation of listening to a channel and receiving data is performed. If data is received in the active window period, a non-activation timer is started. During the running of the non-activation timer, the user equipment is in an active time period and can receive and process data. If the user equipment does not listen to data in the active time period, it enters a sleep state and no longer listens to a channel and receives data, so as to reduce the power consumption of the equipment and achieve the purpose of saving energy.

[0003] The existing 5G sidelink technology is used to build a multi-hop ad hoc network. In a busy business scenario, a relay node or a source node generating data is a data sender. The data sender accumulates a large amount of data in the length of one or more discontinuous cycles and needs to send the data to a neighbor node. The neighbor node is user equipment as a data receiver. Because the active window period is relatively short, some data of the data sender cannot be sent to the data receiver in time in the current active window period. The data sender has to delay the sending for one or even several discontinuous reception cycles, which causes the service quality of the data to be unable to meet the requirements.

[0004] Therefore, there is an urgent need for a method for processing data in the process of 5G sidelink discontinuous reception, which can effectively receive data while achieving energy saving and service quality. SUMMARY

[0005] The present application provides a data processing method, device, system, storage medium and product to solve the problem that the current discontinuous reception method cannot effectively balance the energy saving and service quality of user equipment.

[0006] In a first aspect, the present application provides a data processing method, comprising:

[0007] listening to a physical sidelink control channel in a discontinuous reception active window period to receive a medium access control protocol control element information sent by a data sender according to information carried by the physical sidelink control channel;

[0008] If it is determined that the received media access control protocol control element information includes the extended activation identifier of the data receiver, the activation window period is extended to wait for receiving the data sent by the data sender in the extended activation window period.

[0009] Or,

[0010] If it is determined that the received media access control protocol control element information includes an extended activation identifier bitmap, and the identifier corresponding to the data receiver in the extended activation identifier bitmap is a preset first identifier, the activation window period is extended to wait for receiving the data sent by the data sender in the extended activation window period.

[0011] In the method, when it is monitored that the multiple target data receivers are in the discontinuous reception activation window period, it is determined whether the sum of the byte lengths of the multiple extended activation identifiers corresponding to the multiple target data receivers is greater than the byte length of the extended activation identifier bitmap. If the sum of the byte lengths of the multiple extended activation identifiers is greater than the byte length of the extended activation identifier bitmap, the identifier corresponding to the target data receiver in the extended activation identifier bitmap is set as the preset first identifier, and the media access control protocol control element information including the extended activation identifier bitmap is sent to the multiple neighbor data receivers. If the sum of the byte lengths of the multiple extended activation identifiers is less than or equal to the byte length of the extended activation identifier bitmap, the media access control protocol control element information including the multiple extended activation identifiers is sent to the multiple neighbor data receivers.

If the target data receiver determines that the received media access control protocol control element information includes the extended activation identifier bitmap, and the identifier corresponding to itself in the extended activation identifier bitmap is the preset first identifier, the extended activation window period is extended, so as to wait to receive the data sent by the data sender in the extended activation window period.

[0016] If it is determined that the sum of the byte lengths of the plurality of extended activation identifiers is less than or equal to the byte length of the extended activation identifier bitmap, media access control protocol control element information including the plurality of extended activation identifiers is sent to the neighbor data receivers. If the target data receiver determines that the received media access control protocol control element information includes the extended activation identifier bitmap of itself, the extended activation window period is extended, so as to wait to receive the data sent by the data sender in the extended activation window period.

[0046] The specific embodiments of the present application have been shown by way of example in the above-described drawings and will be described in more detail hereinafter. These drawings and detailed description are not intended to limit the scope of the present application in any way, but to explain the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0047] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same reference numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] Reference is made to Figure 1, 5G sidelink discontinuous reception (Sidelink DRX) power saving scheme diagram, the user equipment as the data receiver automatically wakes up from the starting position of each discontinuous reception cycle, is in the active window period, the active duration of the active window period is determined by the discontinuous reception duration timer (Sidelink-DRX-OnDurationTimer), and the physical sidelink control channel (PSCCH) is executed in the active window period. Listen to, so as to determine the position of the physical sidelink shared channel (PSSCH) according to the information carried by the physical sidelink control channel, and receive the medium access control protocol control element information by using the physical sidelink shared channel. If data sent by the data sender is received in the active window period, start the discontinuous reception inactivity timer (Sidelink-DRX-InactivityTimer), and the user equipment is still in the active time period during the running of the discontinuous reception inactivity timer, and can receive data. If the user equipment does not listen to data in the active time period, it enters a sleep state and no longer listens to the channel and receives data, so as to reduce the power consumption of the user equipment and achieve the purpose of energy saving and power saving.

[0049] The existing 5G sidelink technology is used to build a multi-hop ad hoc network based on groups. In a busy business scenario, a relay node or a source node generating data acts as a data sender, which accumulates a large amount of data in the length of one or more discontinuous cycles and needs to send the data to a neighbor node. The neighbor node as the user equipment of the above-mentioned data receiver, due to the short active window period, some data of the data sender cannot be sent to the data receiver in time in the current active window period, and the data sender has to delay the sending for one or even several discontinuous reception cycles, resulting in that the service quality of the data cannot meet the requirements.

[0050] Therefore, in order to solve the problem that the existing discontinuous reception mode cannot effectively balance the user equipment power saving and service quality, the inventor finds in research that, in the discontinuous reception active window period, a physical sidelink control channel is monitored, media access control protocol control element information sent by a data sender is received according to information borne by the physical sidelink control channel, if it is determined that the received media access control protocol control element information includes an extended active identifier of a data receiver, the active window period is extended, and data sent by the data sender is received in the extended active window period, or if it is determined that the received media access control protocol control element information includes an extended active identifier bitmap and an identifier corresponding to the data receiver in the extended active identifier bitmap is a preset first identifier, the active window period is extended, and data sent by the data sender is received in the extended active window period, wherein, when the data sender monitors that multiple target data receivers are in the discontinuous reception active window period, the data sender determines whether the sum of byte lengths of multiple extended active identifiers corresponding to the multiple target data receivers is greater than the byte length of the extended active identifier bitmap, the data sender determines that the sum of byte lengths of the multiple extended active identifiers is less than or equal to the byte length of the extended active identifier bitmap, and sends media access control protocol control element information including the multiple extended active identifiers to multiple neighbor data receivers, the data sender determines that the sum of byte lengths of the multiple extended active identifiers is greater than the byte length of the extended active identifier bitmap, sets the identifier corresponding to the target data receiver in the extended active identifier bitmap to the preset first identifier, and sends media access control protocol control element information including the extended active identifier bitmap to the multiple neighbor data receivers, the neighbor data receivers include the target data receiver and a non-target data receiver, the user equipment of the data receiver can effectively receive data through the extended active window period, and the power saving and the service quality can be considered at the same time. Moreover, the sum of byte lengths of the multiple extended active identifiers and the byte length of the extended active identifier bitmap are compared to determine the type of the identifier finally sent, and the length of the element information occupied by the multiple identifiers can be effectively reduced.

[0051] Therefore, based on the above creative finding, the inventor proposes the technical scheme of the embodiments of the present application. The network architecture and application scenarios of the data processing method provided by the embodiments of the present application are introduced below.

[0052] As Figure 2As shown, the data processing method provided by the embodiments of the present application corresponds to a network architecture comprising: a user equipment 1, a user equipment 2, a user equipment 3 and a user equipment 4. The user equipment 4 communicates with the user equipment 1, the user equipment 2 and the user equipment 3. The user equipment 1, the user equipment 2 and the user equipment 3 are all data receivers, and the user equipment 4 is a data sender. The user equipment 1, the user equipment 2 and the user equipment 3 are neighbor nodes of the user equipment 4, i.e., neighbor data receivers of the user equipment 4. The user equipment 4 monitors whether the user equipment 1 and the user equipment 2 in the neighbor data receivers are in a discontinuous reception active window period. If it is monitored that the user equipment 1 and the user equipment 2 are both in the discontinuous reception active window period, it is determined whether the sum of the byte lengths of a plurality of extended active identifiers corresponding to the user equipment 1 and the user equipment 2 is greater than the byte length of an extended active identifier bitmap. If it is determined that the sum of the byte lengths of the plurality of extended active identifiers is less than or equal to the byte length of the extended active identifier bitmap, a medium access control protocol control element information including the plurality of extended active identifiers is sent to the neighbor data receivers. If it is determined that the sum of the byte lengths of the plurality of extended active identifiers is greater than the byte length of the extended active identifier bitmap, an identifier corresponding to the target data receiver in the extended active identifier bitmap is set as a preset first identifier, and a medium access control protocol control element information including the extended active identifier bitmap is sent to the plurality of neighbor data receivers (the user equipment 1, the user equipment 2 and the user equipment 3).

[0053] In the method, the user equipment 1, the user equipment 2 and the user equipment 3 listen to a physical sidelink control channel in the discontinuous reception active window period to receive the medium access control protocol control element information sent by the data sender according to the information carried by the physical sidelink control channel. If the user equipment 1 determines that the received medium access control protocol control element information includes the extended active identifier of the user equipment 1, the active window period is extended, and the user equipment 1 waits to receive the data sent by the data sender in the extended active window period. If the user equipment 1 determines that the received medium access control protocol control element information includes the extended active identifier bitmap, and the identifier corresponding to the user equipment 1 in the extended active identifier bitmap is the preset first identifier, the active window period is extended, and the user equipment 1 waits to receive the data sent by the data sender in the extended active window period. The user equipment 2 and the user equipment 3 also extend the active window period by using the above operations.

[0054] The user equipment 13 is a non-target data receiver. If the user equipment 13 determines that the received media access control protocol control element information does not include the extended activation identifier of the user equipment 13, the user equipment 13 enters a sleep state at the end of the activation window period. Alternatively, if the user equipment 13 determines that the received media access control protocol control element information includes the extended activation identifier bitmap and the identifier corresponding to the user equipment 13 in the extended activation identifier bitmap is a preset second identifier, the user equipment 13 enters a sleep state at the end of the activation window period. By extending the activation window period, the user equipment as a data receiver can effectively receive data, and energy saving and service quality can be considered at the same time. Moreover, by comparing the sum of the byte lengths of the plurality of extended activation identifiers with the byte length of the extended activation identifier bitmap, the type of the final transmitted identifier is determined, which can effectively reduce the length of the element information occupied by the plurality of identifiers.

[0055] Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0056] Figure 3 A flowchart of a data processing method provided by the present application is shown. The method is applied to user equipment. The user equipment can be various forms of digital computers, such as cellular phones, smart phones, laptop computers, desktop computers, workstations, personal digital assistants, servers, blade servers, mainframe computers, and other suitable computers. As shown in the figure, the method includes the following steps. Figure 3

[0057] In step 301, a physical sidelink control channel is listened to in a discontinuous reception activation window period, so as to receive media access control protocol control element information transmitted by a data transmitter according to information carried by the physical sidelink control channel.

[0058] The data transmitter is relative to the data receiver. Either party can act as a data receiver or a data transmitter. The data receiver is a user equipment for receiving data, and the data transmitter is a user equipment for transmitting data. When the data transmitter transmits data to the data receiver, the selected transmission occasion needs to be in the activation window period of the data receiver. However, the activation window period of the data receiver is relatively short, so that the data transmitted by the data transmitter cannot be transmitted in time within the current activation window period, and has to be delayed for one or even several discontinuous reception periods to be transmitted completely. Discontinuous reception (DRX) is based on a bursty packet data flow. There is data transmission in a period of time, but there is no data transmission in the next period of time. When there is no data transmission, the power consumption can be reduced by stopping receiving PSCCH and PSSCH, thereby prolonging the battery life.

[0059] ​The data sender of the present application can first extend the active window period of the data receiver, and then send data to the data receiver in the extended active window period. Specifically, the data receiver listens to the physical sidelink control channel in the non-continuous reception active window period, receives the medium access control protocol control element information sent by the data sender according to the information carried by the physical sidelink control channel, and the medium access control protocol control element information includes the extended active identifier or the extended active identifier bitmap of multiple data receivers.

[0060] Optionally, the data sender UE1 needs to send data to the neighbor nodes UE2, UE5 and UE7, which are data receivers relative to UE1. If the data sender determines that the data of UE2, UE5 and UE7 cannot be sent in time in their respective current active window periods, the data sender broadcasts or multicasts the medium access control protocol control element information in the common active window period of UE2, UE5 and UE7, and the medium access control protocol control element information includes the extended active identifier or the extended active identifier bitmap of UE2, UE5 and UE7. In order to reduce the information length, i.e., the byte length, occupied by multiple extended active identifiers, after the data sender allocates the extended active identifiers of the data receivers, when the sum of the byte lengths of multiple extended active identifiers is greater than the byte length of the extended active identifier bitmap, the data sender can use the extended active identifier bitmap instead of multiple extended active identifiers in the subsequently sent medium access control protocol control element information.

[0061] Step 302: If it is determined that the received medium access control protocol control element information includes the extended active identifier of the data receiver, the active window period is extended to wait for receiving the data sent by the data sender in the extended active window period.

[0062] In the present embodiment, if the received medium access control protocol control element information includes the extended active identifier of the data receiver itself, the data receiver extends the active window period, specifically, extends the active window period by starting the non-active timer, or extends the active window period by resetting the timeout length of the duration timer, to wait for receiving the data sent by the data sender in the extended active window period, and the data sender sends data to the data receiver in the extended active window period.

[0063] In step 303, if it is determined that the received media access control protocol control element information includes an extended active identification bitmap, and the identification corresponding to the data receiver in the extended active identification bitmap is a preset first identification, the active window period is extended to wait for the data sent by the data sender in the extended active window period; wherein, the data sender monitors whether multiple target data receivers in the neighbor data receivers are in the discontinuous reception active window period, if it is determined that the multiple target data receivers are in the discontinuous reception active window period, the data sender calculates the sum of the byte lengths of multiple extended active identifications corresponding to the multiple target data receivers, compares the sum of the byte lengths of the multiple extended active identifications with the byte length of the extended active identification bitmap, determines the identification type, if the sum of the byte lengths of the multiple extended active identifications is greater than the byte length of the extended active identification bitmap, the identification corresponding to the target data receiver in the extended active identification bitmap is set to the preset first identification, and the media access control protocol control element information containing the extended active identification bitmap is sent to the multiple neighbor data receivers; if it is determined that the sum of the byte lengths of the multiple extended active identifications is less than or equal to the byte length of the extended active identification bitmap, the media access control protocol control element information including the multiple extended active identifications is sent to the neighbor data receivers, wherein the identification corresponding to the non-target data receiver in the extended active identification bitmap is set to a preset second identification.

[0064] In the embodiment, if it is determined that the received media access control protocol control element information includes an extended active identification bitmap, and the identification corresponding to the data receiver in the extended active identification bitmap is a preset first identification, the active window period is extended; if the identification corresponding to the data receiver is a preset second identification, the data receiver enters a sleep state at the end of the active window period,

[0065] In the embodiment, if it is determined that the received media access control protocol control element information includes an extended active identification bitmap, and the identification corresponding to the data receiver in the extended active identification bitmap is a preset first identification, the active window period is extended; if the identification corresponding to the data receiver is a preset second identification, the data receiver enters a sleep state at the end of the active window period,

[0066] In the embodiment, the user equipment of the data receiver can effectively receive data by extending the activation window period, and meanwhile, the energy saving and the service quality can be considered. Moreover, the sum of the byte lengths of the multiple extended activation identifiers is compared with the byte length of the extended activation identifier bitmap, and the type of the final sent identifier is determined, so that the length of the element information occupied by the multiple identifiers can be effectively reduced.

[0067] Figure 4 Another flowchart of a data processing method is provided in the present application, and the method is applied to user equipment, as shown in Figure 4 The method comprises the following steps.

[0068] In step 401a, a unicast direct link setup request message sent by a data sender is received, and the request message carries an extended activation identifier allocated by the data sender to a data receiver.

[0069] In the embodiment, the unicast direct link setup request message sent by the data sender is received, and the message carries the extended activation identifier allocated by the data sender to the data receiver. For example, if the number of the neighbor nodes of the data sender in the network is N, N positive integers between 1 and N are marked as "unused", and the data sender selects one "unused" number from the N positive integers as the extended activation identifier of the data receiver, for example, selects "K", 1≤K≤N, and marks the selected number as "used".

[0070] Further, in order to reduce the information length, i.e., the byte length, occupied by the multiple extended activation identifiers, when the sum of the byte lengths of the multiple extended activation identifiers is greater than the byte length of the extended activation identifier bitmap, the data sender can use the extended activation identifier bitmap instead of the multiple extended activation identifiers in the media access control protocol control element information sent subsequently. The mapping relationship between the extended activation identifier bitmap and the extended activation identifier needs to be set in advance, for example, the K-1th bit (the bit sequence number starts from 0) of the extended activation identifier bitmap is 1, which indicates that the data receiver corresponding to the extended activation identifier with the number K needs to extend the activation window period; and the K-1th bit of the extended activation identifier bitmap is 0, which indicates that the data receiver corresponding to the extended activation identifier with the number K does not need to extend the activation window period.

[0071] In step 401b, a direct link security mode command message is sent to the data sender, and the command message carries an extended activation identifier allocated by the data receiver to the data sender.

[0072] In the embodiment, the data receiver sends a direct link security mode command message to the data sender, the command message carrying the extended active identifier allocated by the data receiver to the data sender. After receiving the direct link security mode command message, the data sender performs corresponding security mode operation and feeds back a direct link security mode complete message to the data receiver.

[0073] Step 401c, receiving a direct link security mode complete message sent by the data sender.

[0074] In the embodiment, the data receiver receives the direct link security mode complete message fed back by the data sender and further performs corresponding direct link operation.

[0075] It should be noted that if the extended active identifier is not carried in the direct link establishment request message, the extended active identifier can be carried in the direct link security mode complete message.

[0076] Step 401d, sending a direct link establishment accept message to the data sender.

[0077] In the embodiment, the data receiver sends a direct link establishment accept message to the data sender. Optionally, the data sender can modify the extended active identifier previously allocated to its neighbor node by sending a direct link identifier update request message carrying the extended active identifier. The data receiver receives the direct link identifier update request message carrying the extended active identifier, replaces the previous extended active identifier with the extended active identifier, and feeds back a direct link identifier update response message. After receiving the direct link identifier update response message, the data sender releases the extended active identifier previously allocated to the data receiver and marks the extended active identifier as "unused" so as to allocate the extended active identifier to other data receivers.

[0078] Step 401e, receiving a sidelink radio resource control reconfiguration message sent by the data sender, the reconfiguration message being used to indicate a configuration type of the extended active duration.

[0079] Step 401f, if the configuration type is a preset first type, configuring the extended active duration of the active window period corresponding to the first discontinuous reception non-active timer.

[0080] In the embodiment, after the direct link is established, the timeout duration of the related timer needs to be configured. The data receiving side receives a sidelink radio resource control reconfiguration message of the data sending side, the reconfiguration message is used to indicate a configuration type of the extended active duration, specifically, the data receiving side parses the sidelink radio resource control reconfiguration message to obtain the configuration type, if the configuration type is a preset first type, the extended active duration of the active window period corresponding to the first discontinuous reception non-active timer is configured, and the active window period is subsequently extended by starting the first discontinuous reception non-active timer, the active duration of the active window period is extended to the timeout of the first discontinuous reception non-active timer waiting to receive the next data, the timeout duration of the first discontinuous reception non-active timer is greater than the remaining timeout duration of the duration timer and less than the length of the discontinuous reception cycle.

The user equipment can be various forms of digital computers, such as cellular phones, smart phones, laptop computers, desktop computers, workstations, personal digital assistants, servers, blade servers, mainframe computers, and other suitable computers. As shown in the figure, the method includes: Figure 5

[0111] ​Step 501, monitoring whether multiple target data receivers in the neighbor data receivers are in the discontinuous reception active window period.

[0112] In the embodiment, the data sender needs to send data to the target data receivers in the neighbor nodes, and monitors whether multiple target data receivers in the neighbor data receivers are in the discontinuous reception active window period. Generally, the active window period of the data receiver is short, so that the data sent by the data sender cannot be sent in time within the current active window period. The active window period can be extended to ensure that the data can be sent to the target data receiver in time.

[0113] Step 502, if it is monitored that multiple target data receivers are in the discontinuous reception active window period, determining whether the sum of the byte lengths of multiple extended active identifiers corresponding to the multiple target data receivers is greater than the byte length of the extended active identifier bitmap.

[0114] In the embodiment, if it is monitored that multiple target data receivers are in the discontinuous reception active window period, in order to reduce the information length occupied by multiple extended active identifiers, the sum of the byte lengths of multiple extended active identifiers corresponding to the multiple target data receivers is calculated, and the sum of the byte lengths of multiple extended active identifiers corresponding to the multiple target data receivers is compared with the byte length of the extended active identifier bitmap. According to the comparison result, it is determined whether to send the extended active identifier or the extended active identifier bitmap.

[0115] Step 503, if it is determined that the sum of the byte lengths of multiple extended active identifiers is greater than the byte length of the extended active identifier bitmap, setting the identifier corresponding to the target data receiver in the extended active identifier bitmap as a preset first identifier, and sending the medium access control protocol control element information containing the extended active identifier bitmap to multiple neighbor data receivers. If the target data receiver determines that the received medium access control protocol control element information includes the extended active identifier bitmap, and the identifier corresponding to itself in the extended active identifier bitmap is the preset first identifier, the active window period is extended, so as to wait for receiving the data sent by the data sender in the extended active window period.

[0116] In the embodiment, if it is determined that the sum of the byte lengths of the plurality of extended active identifiers is greater than the byte length of the extended active identifier bitmap, the media access control protocol control element information including the broadcast identifier or the groupcast identifier of the data receiver and the extended active identifier bitmap is broadcasted or groupcasted, wherein the identifier corresponding to the target data receiver in the extended active identifier bitmap is set as a first preset identifier. The extended active identifier bitmap can reduce the information length occupied by the plurality of extended active identifiers. The data sender can use the extended active identifier bitmap instead of the plurality of extended active identifiers in the media access control protocol control element information subsequently transmitted, and transmit the media access control protocol control element information including the extended active identifier bitmap to the plurality of neighbor data receivers. It should be noted that the identifier corresponding to the non-target data receiver in the extended active identifier bitmap is set as a second preset identifier, and the non-target data receiver does not need the extended active window period.

[0117] Further, if the target data receiver determines that the received media access control protocol control element information includes the extended active identifier bitmap and the identifier corresponding to itself in the extended active identifier bitmap is the preset first identifier, the extended active window period is extended, so that the data transmitted by the data sender is received in the extended active window period.

[0118] In step 504, if it is determined that the sum of the byte lengths of the plurality of extended active identifiers is less than or equal to the byte length of the extended active identifier bitmap, the media access control protocol control element information including the plurality of extended active identifiers is transmitted to the neighbor data receivers. If the target data receiver determines that the received media access control protocol control element information includes the extended active identifier of itself, the extended active window period is extended, so that the data transmitted by the data sender is received in the extended active window period.

[0119] In the embodiment, if it is determined that the sum of the byte lengths of the plurality of extended active identifiers is less than or equal to the byte length of the extended active identifier bitmap, it indicates that the byte length occupied by the plurality of extended active identifiers is very short, and the plurality of extended active identifiers can be directly used. At this time, the extended active identifier bitmap does not need to be used instead of the plurality of extended active identifiers, and the media access control protocol control element information including the plurality of extended active identifiers is transmitted to the neighbor data receivers.

[0120] Further, if the target data receiver determines that the received media access control protocol control element information includes the extended active identifier of itself, the extended active window period is extended, so that the data transmitted by the data sender is received in the extended active window period. It should be noted that if the target data receiver determines that the received media access control protocol control element information does not include the extended active identifier of itself, the extended active window period is not needed.

[0121] Step 505, sending data to a data receiving party.

[0122] In the embodiment, the data sender sends data to the data receiving party according to the information carried by the physical sidelink control channel, and the data receiving party listens to the physical sidelink control channel in the extended active window period to receive the data sent by the data sender.

[0123] The application can effectively enable the user equipment of the data receiving party to receive data by extending the active window period, and can also take into account energy saving and service quality at the same time. Moreover, comparing the sum of the byte lengths of the multiple extended active identifiers with the byte length of the extended active identifier bitmap to determine the final identifier type can effectively reduce the length of the multiple identifiers occupying element information.

The data sender sets the identifier corresponding to the target data receiving party in the extended active identifier bitmap to the preset first identifier when it is determined that the sum of the byte lengths of the multiple extended active identifiers is greater than the byte length of the extended active identifier bitmap, and sends the medium access control protocol control element information including the extended active identifier bitmap to the multiple neighbor data receiving parties.
