Detailed Description
For a better understanding of the technical solutions of the present specification, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.
It should be understood that the described embodiments are only some, but not all, of the embodiments of the present description. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present disclosure.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Aiming at the problem that the parameters set by the current Bluetooth protocol are shared and redundant, the embodiment of the invention provides a Bluetooth receiving and transmitting time sequence control method, which can accurately control the time interval between air interface data packets by setting corresponding time sequence control parameter sets for different physical channels and reduces the conditions of shared and redundant control parameters.
Fig. 1 is a flowchart of a bluetooth transceiver timing control method according to an embodiment of the present invention. The method can be applied to terminal equipment (such as a smart phone, a Bluetooth headset and the like) with a Bluetooth function, and as shown in fig. 1, the method can comprise the following steps:
step 101, determining the data type of the air interface data packet to be transmitted.
Step 102, determining a physical channel corresponding to each air interface data packet according to the data type, wherein each physical channel is configured with a corresponding time sequence control parameter set, and the time sequence control parameter set comprises a plurality of time sequence control parameters.
In the embodiment of the invention, a physical channel can be formed after Bluetooth connection is established between the terminal devices, and the data to be transmitted is transmitted on the physical channel by taking the air interface data packet as a unit, so that the data interaction between the terminal devices is realized. The air interface data packets have corresponding data types, and the terminal equipment can determine physical channels suitable for transmitting the air interface data packets according to the data types and time sequence control parameters required for realizing stable transmission of the air interface data packets. The terminal device may configure a plurality of timing control parameter sets in advance, each of the timing control parameter sets including a plurality of timing control parameters. The terminal equipment can associate the corresponding data type, physical channel and time sequence control parameter set, and when the air interface data packet is transmitted, the terminal equipment can determine the physical channel and time sequence control parameter set of the air interface data packet according to the preset association relation only by acquiring the data type of the air interface data packet to be transmitted.
In one embodiment, the air interface data packet includes a receiving packet and a transmitting packet, and the terminal device may set six timing control parameters including a receiving packet interval, a receiving packet distance, a transmitting packet interval, a transmitting packet distance, an event interval, and an event distance in advance, where each set of timing control parameters includes one or more of the six timing control parameters. Specifically, the event interval is a time interval from a first byte of a current bluetooth event to a first byte of a next bluetooth event, and the event distance is a time interval from a last byte of the current bluetooth event to the first byte of the next bluetooth event, wherein each bluetooth event comprises one or more air interface data packets; the transmission packet interval is the time interval from the first byte of the current transmission packet to the first byte of the next air interface packet, and the transmission packet distance is the time interval from the last byte of the current transmission packet to the first byte of the next air interface packet; the received packet interval is the time interval from the first byte of the current received packet to the first byte of the next air interface packet, and the received packet distance is the time interval from the last byte of the current received packet to the first byte of the next air interface packet.
Step 103, controlling the transmission of the air interface data packets on the corresponding physical channels based on the time sequence control parameters, so that the time intervals among different air interface data packets meet the preset standard.
In one embodiment, the physical channel includes a data physical channel, and the timing control parameter set includes a first timing control parameter set, where the first timing control parameter set includes a transmission packet distance, a reception packet distance, and a time distance. The terminal device may set the transmission packet distance, the reception packet distance and the time distance to appropriate values, so that when the air interface data packet is transmitted on the data physical channel, the time intervals between different air interface data packets conform to a preset standard. Alternatively, the preset standard may be a standard specified in the bluetooth protocol. A specific transmission scenario may be shown in fig. 2, where TX is a transmission packet, RX is a reception packet, each event includes a plurality of air-interface packets, and in fig. 2, event x and event x+1 only show 12 air-interface packets, but in an actual scenario, each event may include more air-interface packets, which are not shown. In actual transmission, devices connected through bluetooth may be divided into a center device and peripheral devices, and there may be only one center device and a plurality of peripheral devices. Such as a smart phone (central device) may be connected to a plurality of devices such as a bluetooth headset (peripheral device), a bluetooth sound, etc. When the central device transmits the air interface data packet (transmission packet), the peripheral device needs to receive the air interface data packet (reception packet), and when the peripheral device transmits the air interface data packet, the central device needs to receive the air interface data packet. Taking fig. 2 as an example, at the same time, when the central device is TX, the peripheral device needs to be RX. When the physical channel is a data physical channel, the center device and the peripheral device may each set the transmission packet distance, the reception packet distance, and the event distance to a first value. Alternatively, the first value may be set to 150us based on the bluetooth protocol. The time interval between the last byte in the sending packet and the first byte in the receiving packet is 150us, the time interval between the last byte in the receiving packet and the first byte in the receiving packet is 150us, the time interval between the last byte in the event x and the first byte in the event x+1 is 150us, and the terminal equipment realizes the stable transmission of the air interface data packet based on the three time sequence control parameters.
In one embodiment, the physical channel includes a broadcast physical channel, and the timing control parameter set includes a second timing control parameter set, where the second timing control parameter set includes a transmission packet interval, a reception packet interval, and an event interval. The terminal device may set the transmission packet interval, the reception packet interval, and the event interval to appropriate values, so that when the air interface data packet is transmitted on the broadcast physical channel, the time interval between different air interface data packets accords with a preset standard. As shown in fig. 3A, if the terminal device is a central device, the transmission packet interval may be set to a second value, the reception packet interval may be set to 0, and the event interval may be set to a third value; if the terminal device is a peripheral device, the received packet interval may be set to a second value, the transmitted packet interval may be set to 0, and the event interval may be set to a third value. Since the reception packet interval or the transmission packet interval is set to 0, the specific transmission scenario may transition to that shown in fig. 3B. The broadcast physical channel is mainly used for unidirectional transmission, and in general, the central device sends an air interface data packet, and the peripheral device receives the air interface data packet.
In one embodiment, the physical channel includes a first synchronous physical channel, and the timing control parameter set includes a third timing control parameter set, where the third timing control parameter set includes a transmission packet interval, a reception packet interval, and an event interval. The terminal device may set the transmission packet distance, the reception packet distance, and the event interval to appropriate values, so that when the air interface data packets are transmitted on the first synchronous physical channel, the time intervals between different air interface data packets conform to a preset standard. Wherein the first sync physical channel may refer to a sync physical channel in a connected sync group (Connected Isochronous Group, CIG) scenario. As shown in fig. 4, if the terminal device is a central device, the distance between the sending packets may be set to a fourth value, and the event interval may be set to a fifth value or a sixth value; if the terminal device is a peripheral device, the received packet interval may be set to a fourth value, and the event interval may be set to a fifth value or a sixth value. The fourth value may be set to 150us, and the events m to m+n form a connection synchronization group, and an event not shown may be included between the event m+2 and the time m+n. The time interval between the last byte of the connection sync group and the first byte of the next connection sync group is larger, so the event interval of the last event included in the connection sync group is the sixth value, and the other event intervals are the fifth values. The terminal device can change other physical channels after the last event of each connection synchronization group is finished.
In one embodiment, the physical channel includes a second synchronous physical channel, and the timing control parameter set includes a fourth timing control parameter set, where the fourth timing control parameter set includes a transmission packet interval, a reception packet interval, and an event interval. The terminal device may set the transmission packet interval, the reception packet interval, and the event interval to appropriate values, so that when the air interface data packet is transmitted on the second synchronous physical channel, the time interval between different air interface data packets accords with a preset standard. Wherein the second sync physical channel may refer to a sync physical channel in a connected broadcast sync group (Broadcast Isochronous Group, BIG) scenario. As shown in fig. 5, if the terminal device is a central device, the transmission packet interval may be set to a seventh value, the reception packet interval is set to 0us, and the event interval is set to an eighth value; if the terminal device is a peripheral device, the receive packet interval may be set to a seventh value, the transmit packet interval may be set to 0us, and the event interval may be set to an eighth value. In a specific transmission scenario, in which the central device only sends air interface packets and the peripheral device only receives air interface packets, the seventh value may be set to 150us, similar to the broadcast physical channel.
In the embodiment of the invention, the terminal equipment sets six time sequence control parameters in advance, and can realize stable transmission of the air interface data packet on each physical channel by selecting different time sequence control parameters on different physical channels and setting the time sequence control parameters as different values, thereby simplifying the number of the control parameters and reducing the conditions of sharing and redundancy of the control parameters.
Fig. 6 is a flowchart of another bluetooth transceiver timing control method according to an embodiment of the present invention. As shown in fig. 6, the method may include:
in step 601, an air interface packet to be transmitted is determined.
Step 602, determining physical channels and timing control parameters according to the data type.
Wherein the physical channels include a data physical channel, a broadcast physical channel, and a sync physical channel. The timing control parameters include a first timing control parameter set, a second timing control parameter set, a third timing control parameter set, and a fourth timing control parameter set.
The data physical channel uses the first set of timing control parameters, step 603.
The first set of timing control parameters includes three timing control parameters, a transmit packet distance, a receive packet distance, and an event distance.
The broadcast physical channel uses a second set of timing control parameters, step 604.
The second set of timing control parameters includes three timing control parameters, a transmit packet interval, a receive packet interval, and an event interval.
Step 605, synchronize the physical channel using the third, fourth timing control parameter set.
The third time sequence control parameter set comprises three time sequence control parameters of a sending packet distance, a receiving packet distance and an event interval, and the fourth time sequence control parameter set comprises three time sequence control parameters of a sending packet interval, a receiving packet interval and an event interval. The third time sequence control parameter is used for the synchronous physical channel in the CIG scene, and the fourth time sequence control parameter is used for the synchronous physical channel in the BIG scene.
Step 606, a timing control is sent.
And step 607, the transmission is finished and the result is reported.
