Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a transmission control method, device, equipment, chip and medium. Background Art

[0002] In the field of communication technology, two isochronous (ISO) transmission methods can be used to transmit data information. The first is connected unicast ISO (CIS), and the second is connectionless broadcast ISO (BIS). CIS can only allow the transmission of a unidirectional or bidirectional data message between a pair of devices. When transmitting multiple time-related data messages, the master device needs to organize multiple CISs and schedule them concurrently according to certain rules to ensure that each CIS data message can be synchronously received by multiple slave devices. In BIS, there is no bidirectional connection between the master and the slave, and the slave cannot send packets, nor can it report an acknowledgment mark (Acknowledge, ACK). Therefore, the master device needs to send a message in each subevent of the isochronous link to ensure that each slave device can correctly receive the data information.

[0003] In the related art, the transmission of data information consumes a large amount of power and consumes a large amount of air interface resources. Summary of the invention

[0004] The present disclosure aims to solve one of the technical problems in the related art at least to some extent.

[0005] To this end, the present disclosure proposes a transmission control method, apparatus, communication equipment, chip and storage medium to reduce the transmission power consumption of data information and save air interface resources.

[0006] The first aspect embodiment of the present disclosure proposes a transmission control method, including: sending data information by broadcasting; determining whether first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information; and controlling the transmission of the data information according to the reference result.

[0007] The second aspect embodiment of the present disclosure proposes a transmission control device, including: a transceiver module, used to send data information by broadcasting; a determination module, used to determine whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information; a control module, used to control the transmission of the data information according to the reference result.

[0008] The third aspect embodiment of the present disclosure proposes a communication device, including: a processor, and a memory communicatively connected to the processor; the memory stores computer execution instructions; the processor executes the computer execution instructions stored in the memory to implement the transmission control method proposed in the first aspect embodiment of the present disclosure.

[0009] The fourth aspect embodiment of the present disclosure proposes a chip, which includes a processing circuit and an interface circuit; wherein the interface circuit is used to read instructions, and the interface circuit sends the instructions to the processing circuit so that the processing circuit executes the transmission control method proposed in the first aspect embodiment of the present disclosure.

[0010] The fifth aspect of the present disclosure provides a computer-readable storage medium, in which computer-executable instructions are stored. When the computer-executable instructions are executed by a processor, they are used to implement the transmission control method as described above.

[0011] The transmission control method, device, communication device, chip and storage medium provided by the present disclosure can send data information by broadcasting, and determine whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information, and to control the transmission of the data information according to the reference result. Since the data information can be broadcasted, and after the data information is broadcasted, it is determined whether the first information sent by all communication devices has been received to obtain a reference result, and then the data information is controlled for transmission based on the reference result, there is no need to send the data information separately, and subsequent transmission control can also be performed based on the actual situation of whether the first information sent by all communication devices has been received, thereby effectively reducing the transmission power consumption of the data information and saving air interface resources.

[0038] In the related art, the transmission of data information consumes a large amount of power and consumes a large amount of air interface resources.

[0039] In order to solve the above technical problems, the embodiments of the present disclosure can send data information by broadcasting, and determine whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information, and to control the transmission of the data information according to the reference result. Since the data information can be broadcasted, and after the data information is broadcasted, it is determined whether the first information sent by all communication devices has been received to obtain a reference result, and then the data information is controlled based on the reference result, there is no need to send the data information separately, and the subsequent transmission control can also be performed based on the actual situation of whether the first information sent by all communication devices has been received, thereby effectively reducing the transmission power consumption of the data information and saving air interface resources.

[0040] The data information in the embodiments of the present disclosure may be, for example, audio data, image data, multimodal data, video data, etc., without limitation.

[0041] The communication device in the embodiments of the present disclosure may be used to send each frame of data information (in this case, the communication device may also be referred to as a master device), or the communication device may also be used to receive each frame of data information (in this case, the communication device may also be referred to as a slave device).

[0044] Figure 2 A flow chart of a transmission control method provided by an embodiment of the present disclosure.

[0045] like Figure 2 As shown, the transmission control method includes:

[0046] Step S201: Send data information via broadcasting.

[0047] Among them, the broadcast mode refers to a communication mode.

[0048] Optionally, in some embodiments, the data information may be sent to all slave devices connected to the network based on a broadcasting manner, rather than to a specific single slave device.

[0049] Optionally, in some embodiments, the number of frames of the data information may be one frame or multiple frames. At least one frame of data information may be sent in a broadcasting manner.

[0050] Optionally, in some embodiments, the master device may establish a MIS link with each slave device, and then send data information in each MIS link by broadcasting. Optionally, in some embodiments, the master device may determine that data information needs to be sent, and then use the transmission control method provided in the embodiment of the present disclosure to implement transmission control of the data information, which may be specifically described below.

[0051] Step S202: Determine whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information.

[0052] Here, "all communication devices" refers to all communication devices that need to receive data information in the application scenario.

[0053] The first information may be specifically, for example, an ACK flag. Optionally, in some embodiments, the first information may be used to indicate that the slave device has correctly received the data information. In other words, if the slave device feeds back the first information, it indicates that the slave device has correctly received the data information.

[0054] Optionally, in some embodiments, after sending the data information by broadcasting, it is possible to monitor whether each slave device feeds back first information that the data information has been correctly received to obtain a reference result. The reference result is used to indicate whether the first information sent by all slave devices has been received.

[0055] Optionally, in some embodiments, the master device may send data information by broadcasting, and after correctly receiving the data information, the slave device may feed back the first information to the master device through the MIS link between the master device and the master device to indicate to the master device that the data information has been correctly received. The master device may determine whether the first information sent by all slave devices has been received to obtain a reference result, and the master device may control the transmission of the data information based on the reference result.

[0056] Step S203: Control the transmission of data information according to the reference result.

[0057] Optionally, in some embodiments, data information transmission control may be implemented based on reference results. For example, the reference results may be analyzed in combination with some control rules agreed upon in the protocol, and data information transmission control may be implemented based on the analysis, or artificial intelligence may be combined to implement data information transmission control based on the reference results, or data information transmission control may be implemented based on any other possible method, without limitation.

[0058] Optionally, in some embodiments, the transmission control of data information may be, for example, whether the data information needs to be broadcast again, whether it needs to indicate that the transmission of the data information has been stopped, etc., and there is no limitation on this.

[0059] In this embodiment, data information can be sent by broadcasting, and it is determined whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information, and the transmission of the data information is controlled according to the reference result. Since the data information can be broadcasted, and after the data information is broadcasted, it is determined whether the first information sent by all communication devices has been received to obtain a reference result, and then the transmission of the data information is controlled based on the reference result, it is not necessary to send the data information separately, and subsequent transmission control can also be performed based on the actual situation of whether the first information sent by all communication devices has been received, thereby effectively reducing the transmission power consumption of the data information and saving air interface resources.

[0060] Figure 3 A flowchart of another transmission control method provided by an embodiment of the present disclosure.

[0061] like Figure 3 As shown, the transmission control method includes:

[0062] Step S301: Send data information via broadcasting.

[0063] Step S302: Determine whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information.

[0064] For the description of step S301 - step S302 , please refer to the above embodiment for details, which will not be repeated here.

[0065] Step S303: When the reference result is that the first information sent by all communication devices has been received, second information is sent by broadcasting, wherein the second information is used to indicate to stop transmitting data information.

[0066] The second information may be used to indicate the stop of transmitting data information. The second information may be, for example, a flag bit (CIE) for ending the current transmission event. If the second information is indicated, there is no need to transmit data information in subsequent sub-events. The sub-event may be a transmission event. A transmission event may include multiple sub-events. A transmission event may be understood as a time unit. The transmission of a frame of data information is completed on at least one sub-event in a transmission event. For a specific description of the transmission event, please refer to the subsequent embodiments.

[0067] Optionally, in some embodiments, when it is determined that the first information sent by all slave devices has been received, indicating that each slave device has correctly received the frame data information, a second information may be sent by broadcasting to notify to stop transmitting the frame data information. Thus, there is no need to send the same frame data information according to the maximum number of retransmissions, thereby reducing the number of retransmissions of the data information, and can largely support reducing the transmission power consumption of the data information, thereby quickly saving air interface resources.

[0068] Optionally, in some embodiments, sending the second information by broadcasting includes: sending the second information by broadcasting at a sub-event next to the sub-event corresponding to the first sending time point, thereby ensuring that each slave device can receive the second information in a timely manner and determine that it has been instructed to stop transmitting the frame data information based on the second information.

[0069] The first sending time point refers to a sending time point corresponding to a sub-event used for transmitting the current frame of data information. For a description of the first sending time point, please refer to the subsequent embodiments.

[0070] That is to say, if it is determined that each slave device has correctly received the frame data information, the second information can be sent by broadcasting on the next sub-event of the sub-event used to transmit the current frame data information. In this way, efficient scheduling control can be achieved to ensure that the second information can be correctly received.

[0071] Step S304: when the reference result is that the first information sent by all the communication devices is not received, the data information is sent again by broadcasting until the first information sent by all the communication devices is received.

[0072] Optionally, in some embodiments, when it is determined that the first information sent by all slave devices has not been received, it means that at least one slave device has not correctly received the frame data information. In order to ensure that the data information can be correctly received by all slave devices and ensure the accuracy of the audio playback, the data information can be sent again via broadcast until the first information sent by all slave devices is received, and the second information is sent via broadcast, and there is no restriction on this.

[0073] In this embodiment, data information can be sent by broadcasting, and it is determined whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information, and to control the transmission of the data information according to the reference result. Since the data information can be broadcasted, and after the data information is broadcasted, it is determined whether the first information sent by all communication devices has been received to obtain a reference result, and then the data information is controlled for transmission based on the reference result, it is not necessary to send the data information separately, and subsequent transmission control can also be performed based on the actual situation of whether the first information sent by all communication devices has been received, thereby effectively reducing the transmission power consumption of the data information and saving air interface resources. In the case of determining that the first information sent by all communication devices has been received, that is, each communication device has correctly received the frame data information, the second information can be sent by broadcasting to notify the stop of the transmission of the frame data information, thereby, there is no need to send the same frame data information according to the maximum number of retransmissions, reducing the number of retransmissions of the data information, and can largely support the reduction of the transmission power consumption of the data information, thereby quickly saving air interface resources. When the reference result is that the first information sent by all communication devices is not received, the data information is sent again by broadcasting until the first information sent by all communication devices is received. Since the broadcasting method is still used when the data information is sent again, the transmission power consumption of the data information can be effectively reduced each time the data information is retransmitted, thereby saving air interface resources to a large extent. It can also ensure that the data information can be correctly received by all communication devices and ensure the accuracy of audio playback.

[0074] Figure 4 A flowchart of another transmission control method provided by an embodiment of the present disclosure.

[0075] like Figure 4 As shown, the transmission control method includes:

[0076] Step S401: determining event parameters of the isochronous link, wherein the event parameters are used to describe a transmission event in the isochronous link, and the transmission event includes: a plurality of sub-events.

[0077] Optionally, in some embodiments, the master device may send data information via broadcast, the master device may establish a MIS link with each slave device, and the master device may transmit data information in each MIS link via broadcast.

[0078] Optionally, in some embodiments, the isochronous link may have corresponding event parameters, and the event parameters may be configured during the process of building the isochronous link. The event parameters may be used to describe transmission events in the isochronous link, and the transmission events include: multiple sub-events.

[0079] The transmission event may also be referred to as an Event. A transmission event may include multiple sub-events, and event parameters may be used to describe information related to the sub-events, which is not limited.

[0080] The number of isochronous links may be one or more. One isochronous link corresponds to one slave device, and one isochronous link may be used to transmit multiple frames of data information to the corresponding slave device. Each isochronous link may contain multiple sub-events, and each sub-event may be used to transmit data information to the corresponding slave device. Multiple isochronous links may constitute an isochronous transmission group.

[0081] Optionally, in some embodiments, the event parameter includes at least one of the following: first time information and second time information. The first time information indicates the time difference between the anchor time point and the reference time point of the isochronous transmission group to which the isochronous link belongs, and the second time information indicates the time interval between two adjacent sub-events in the transmission event.

[0082] The anchor time point is used to time-align the transmission of sub-events of different isochronous links in the isochronous transmission group. The anchor time point can also be called Anchor Point. The reference time point of the isochronous transmission group can also be called Reference Point.

[0083] The first time information and the second time information mentioned above can be used to determine the sending time point of each sub-event in a transmission event.

[0084] Step S402: Determine the sending time point corresponding to each sub-event according to the event parameters.

[0085] Optionally, in some embodiments, in the process of determining the sending time point corresponding to each sub-event according to the event parameters, the reference time point of the isochronous transmission group may be determined, and the sending time point corresponding to each sub-event may be determined according to the reference time point of the isochronous transmission group, the first time information, and the second time information. In this way, it is possible to ensure that the transmission of data information is accurately scheduled on each sub-event, thereby improving the accuracy of data information transmission control.

[0086] Optionally, in some embodiments, in the process of determining the sending time point corresponding to each sub-event according to the reference time point, the first time information and the second time information of the isochronous transmission group, the anchor time point can be determined according to the reference time point and the first time information of the isochronous transmission group, and the anchor time point is used as the sending time point of the first sub-event among the multiple sub-events, and the sending time point corresponding to each sub-event in the remaining sub-events is determined according to the sending time point of the first sub-event and the second time information. In this way, it is possible to ensure that the transmission of data information is accurately scheduled on each sub-event, thereby improving the accuracy of data information transmission control.

[0087] For example, when determining the anchor time point based on the reference time point and the first time information of the isochronous transmission group, the reference time point and the cumulative value of the time value indicated by the first time information can be used as the anchor time point, and then the anchor time point can be used as the sending time point of the first sub-event among multiple sub-events. The first sub-event can also be represented as SubEvent0. The second time information can also be represented as a sub-event interval (sub_interval). After determining the sending time point of the first sub-event, the time value indicated by the second time information can be accumulated at the sending time point of the first sub-event, and the time value can be used as the sending time point of the next sub-event adjacent to the first sub-event, and so on, to determine the sending time point corresponding to each sub-event.

[0088] It should be noted that, in the embodiments of the present disclosure, the reference time point of the isochronous transmission group can be used to perform time synchronization on multiple isochronous links included in the isochronous transmission group, so as to ensure that the sending time point of the first sub-event in the transmission events of different isochronous links is the same, and ensure that the sending time points of sub-events of corresponding orders in the transmission events of different isochronous links are the same, that is, the first time information of different isochronous links in the isochronous transmission group can be the same, and the second time information can also be the same.

[0089] Step S403: when the current time point reaches the first sending time point, data information is sent on the sub-event corresponding to the first sending time point by broadcasting, wherein the first sending time point belongs to multiple sending time points.

[0090] Among them, the first sending time point can be the sending time point of the first sub-event, or if after sending a frame of data information on the first sub-event, if it is determined that the frame of data information needs to be retransmitted, the first sending time point can be the sending time point of the next sub-event adjacent to the first sub-event, and there is no restriction on this.

[0091] That is to say, if it is detected that the current time point reaches a certain sending time point (the sending time point adjacent to the current time point may be referred to as the first sending time point), the data information may be sent at the sub-event corresponding to the first sending time point by broadcasting. After each broadcast sending of the data information, steps S404 and S405 may be executed to control the transmission of the frame data information, for example, after each broadcast sending of the data information, it is determined whether to send the data information again, or whether to broadcast a notification to stop the transmission of the data information.

[0092] Step S404: Determine whether the first information sent by all communication devices has been received, and obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information.

[0093] Step S405: Control the transmission of data information according to the reference result.

[0094] In this embodiment, data information can be sent by broadcasting, and it is determined whether the first information sent by all communication devices has been received to obtain a reference result, wherein the first information is used to indicate that the communication device has correctly received the data information, and the data information is transmitted and controlled according to the reference result. Since the data information can be broadcasted, and after the data information is broadcasted, it is determined whether the first information sent by all communication devices has been received to obtain a reference result, and then the data information is transmitted and controlled based on the reference result, it is not necessary to send the data information separately, and the subsequent transmission control can also be performed based on the actual situation of whether the first information sent by all communication devices has been received, so that the transmission power consumption of the data information can be effectively reduced and the air interface resources can be saved. By determining the event parameters of the isochronous link, wherein the event parameters are used to describe the transmission event in the isochronous link, the transmission event includes: multiple sub-events, and according to the event parameters, the transmission time point corresponding to each sub-event is determined, and when the current time point reaches the first transmission time point, the data information is sent on the sub-event corresponding to the first transmission time point by broadcasting, wherein the first transmission time point belongs to multiple transmission time points. Thus, it is possible to ensure that the transmission of data information is accurately scheduled on each sub-event, and improve the accuracy of data information transmission control.

[0095] Optionally, in some embodiments of the present disclosure, after each transmission of data information, third time information corresponding to each first information may be determined, wherein the third time information indicates the time point at which the first information is sent, and based on the third time information, the corresponding first information is received. Thus, it is possible to receive each first information at a preset time point, ensuring that each first information can be accurately received.

[0096] The examples for the above embodiment are as follows:

[0097] like Figure 5 As shown, Figure 5 It is an application diagram of an embodiment of the present disclosure. Taking the master device as the host, the master device broadcasts an audio message (an optional example of data information) to two slave devices (for example, slave 1 and slave 2) for example, and the first information is, for example, an ACK flag. Among them, MIS1 represents the MIS link between the host and slave 1, and MIS2 represents the MIS link between the host and slave 2. Slave 1 and slave 2 can have the same anchor time point (AnchorPoint). Figure 5 In the embodiment, there is a host using MIS link and two slaves using MIS link. The audio message sent by the host (sent by broadcasting) is received by multiple slaves, and each slave sends a response message with an ACK flag at a preset time point. When all slaves have sent the response message, the host can terminate the sending of the audio message and start the sending of the next audio message at the agreed time, thereby saving the number of repeated sending of the audio message, saving air interface time and power consumption.

[0098] like Figure 6 As shown, Figure 6 It is another application schematic diagram in the embodiment of the present disclosure. Figure 6The time scheduling process is shown in . Take the host as Centrol, which contains two slaves (Peripheral 1 and Peripheral 2) as an example. Tx means "transmit or send", the transmission event can be expressed as MIS Event, the isochronous link group is expressed as MIG, the isochronous link is expressed as MIS Link, each transmission event contains two sub-events (MIS SubEvent0 and MIS SubEvent1), MIG ReferencePoint represents the reference time point of the isochronous link group, and MIG Sync Point represents the synchronization time point of the isochronous transmission group. Centrol can broadcast and send Centrol Tx (indicating a frame of data information sent by Centrol), and Peripheral 1 and Peripheral 2 can respectively send response Peri Tx (indicating response information sent by Peripheral). Peripheral1 can send response Peri Tx based on MIS1Delay, and Peripheral 2 can send response PeriTx based on MIS2Delay. After sending Centrol Tx once each time, Centrol can determine whether all Peripherals have correctly received Centrol Tx. If Peripheral has correctly received Centrol Tx, Peripheral will send Peri Tx containing ACK mark to Centrol. If Centrol determines that it has received PeriTx containing ACK mark fed back by all Peripherals, it does not need to retransmit Centrol Tx again. If Centrol determines that it has not received Peri Tx containing ACK mark fed back by all Peripherals, it needs to retransmit Centrol Tx again. That is to say, in this process, Centrol will transmit Centrol Tx at least once, and each time Centrol Tx is transmitted, Centrol Tx is transmitted on the corresponding sub-event of the transmission event of the MIS link between Centrol and Peripheral.

[0099] like Figure 7 As shown, Figure 7 It is a schematic diagram of the use of CIE in the embodiment of the present disclosure. CIE refers to a flag used to end the current transmission event. If the Centrol determines that it has received ACK feedback from all Peripherals, there is no need to retransmit the Centrol Tx again. Instead, the CIE is sent by broadcast in the next sub-event (MIS SubEvent2) to instruct each Peripheral to end the current transmission event, that is, the frame data information is no longer retransmitted.

[0100] In the disclosed embodiment, there is no need to transmit data information according to the maximum number of retransmissions, and there is no need to send the same data information to multiple CISs respectively, thereby effectively saving power consumption and air interface resources.

[0102] like Figure 8 As shown, the transmission control method includes:

[0103] Step S801: the master device sends data information via broadcast.

[0104] Step S802: The slave device determines that the data information has been correctly received.

[0105] Step S803: Send first information to the master device.

[0106] The first information is used to indicate that the slave device has correctly received the data information.

[0107] Step S804: The master device determines whether the first information sent by all slave devices has been received to obtain a reference result.

[0108] Step S805: When the reference result is that the first information sent by all slave devices has been received, the master device sends the second information by broadcasting.

Thus, there is no need to send the same frame of data information according to the maximum number of retransmissions, and the number of retransmissions of the data information is reduced, which can greatly support the reduction of the transmission power consumption of the data information, thereby quickly saving air interface resources. And each time the data information is retransmitted, the transmission power consumption of the data information can be effectively reduced, thereby saving air interface resources to a large extent. It can also ensure that the data information can be correctly received by all slave devices, and ensure the accuracy of audio playback.

[0126] Step S907: LL B sends a MIS link request message to slave B.

[0127] The MIS link request message is used to request slave B to agree to establish the MIS link.

[0128] Step S908: Slave B sends a MIS link accept command to LLB.

[0129] The MIS link accept command is used to notify permission to establish the MIS link.

[0130] Step S909: LL B feeds back the command status to slave B.

[0131] Step S910: LL B sends a MIS link response message to LL A.

[0132] Among them, the MIS link response message is used to notify the acceptance of establishing the MIS link.

[0133] Step S911: LL A sends a MIS link notification message to LL B.

[0134] Among them, the MIS link notification message is used to notify the time to start the MIS link.
