Description
Technical Field
The present application relates to the field of communications, and in particular, to a wireless communication method and a communication device.
Background
IEEE802.11 is one of the most widely used local area network protocols at present, but with the rapid development of wireless local area networks, the user's demand for quality of service (QoS) is increasing. In order to improve the support of the transmission Medium Access Control (MAC) layer for QoS, the IEEE802.11e standard is proposed by the IEEE working group, and the HCF mechanism defined by the standard effectively guarantees the QoS of the MAC layer. Two access channel mechanisms are defined in HCF: enhanced Distributed Channel Access (EDCA) and HCF Controlled Channel Access (HCCA), where the chance of a user obtaining a transmission is represented by a transmission opportunity (TXOP), which consists of an initial time and a maximum duration TXOP Limit, which represents that a device has the right to transmit data at a certain time, and the device obtaining the TXOP may no longer re-contend for the channel within the TXOP Limit time, and continuously transmit a plurality of data frames using the channel. In the prior art, a device may obtain a TXOP in a contention mode to access a channel, and transmit a data frame within a TXOP Limit time.
However, in the prior art, after a certain device contends for the TXOP, other devices adopt a back-off mode, and after the time of the TXOP Limit elapses, the next contention is performed. For example, suppose that two devices a and B are performing data transmission, if a has a TXOP, a may transmit a data packet to B using the TXOP, and B may only wait until a TXOP is contended and then transmit data back to a, if the contention time of B is long, for example, in a voice call service, if a sends data to B through the contended TXOP and B contends for another TXOP to transmit data back after a long time, noise and other situations may occur in the voice call service, so that the service quality may not be guaranteed.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a schematic diagram of an embodiment of a possible wireless communication method according to an embodiment of the present application is provided, where the method includes:
101. the first device confirms that the second device has the capacity of sharing the TXOP;
TXOP, refers to a time interval. After the device successfully acquires the channel access right, the device does not need to compete with other nodes for the channel again in the time interval, and can continuously send a plurality of data frames, but cannot exceed the length limit of the time interval. The larger the TXOP, the more channel time the device may occupy to transmit more data frames. For convenience of description, in the embodiment of the present application, a device that obtains a TXOP through contention, that is, an owner of the TXOP is referred to as a first device, and when the first device and a second device have data transmission, the first device confirms that the second device has a capability of sharing the TXOP. It can be understood that, in practical applications, there are various ways for the first device to confirm that the second device has the capability of sharing the TXOP, for example, when the first device is connected to the second device, the first device may send a first message to the second device, where the first message is used to indicate whether the second device reports the capability of supporting the shared TXOP, and after receiving the first message, the second device sends a first message response to the first device, so that the first device confirms whether the second device has the capability of sharing the TXOP through the first message response. Or, in a process of connecting the first device and the second device, the first device receives a frame sent by the second device, where the frame includes information indicating whether the second device has a capability of sharing the TXOP, where the frame may be a Clear To Send (CTS) frame or a Request To Send (RTS) frame, and thus the first device may confirm whether the second device has the capability of sharing the TXOP through the frame sent by the second device. In addition, the time for the first device to confirm that the second device has the capability of sharing the TXOP may be when the first device establishes a connection with the second device, and the first device may also actively trigger the second device to send second indication information or actively report the second indication information by the second device, where the second indication information is used to indicate that the second device has the capability of sharing the TXOP, and therefore, a manner for the first device to confirm that the second device has the capability of sharing the TXOP is not limited herein.
In addition, in this embodiment of the application, the first device may be an AP, and the second device may be an STA; the first device may also be an STA and the second device may be an AP. It should be noted that the STA may be a suitable device connected to the distributed network through a wireless link. For example, the STA may be a mobile computer, a personal digital assistant, an internet of things (IoT) device (e.g., a smart watch, a smart bracelet, etc.), a portable device (e.g., a cellular GPRS phone), an Ultra Wide Band (UWB) device, or a wireless device, and the like, which is not limited herein.
Alternatively, an AP may include, be implemented by, or be referred to as a Radio Network Controller (RNC), a node B, an evolved node B, a base station controller, a base transceiver station, a base station, a transceiver function, a radio router, a radio transceiver, or some other terminology, which is not specifically limited herein.
It should be noted that, the embodiments of the present application are not limited to GPRS and WLAN networks, and may also be networks in which stations and a central controller (i.e., an AP in a WLAN and a base station in a GPRS) communicate at different physical transmission rates, and are not limited herein.
102. The first equipment configures first indication information in a scrambling code sequence;
it should be noted that, in digital communication, if a long 0 or 1 sequence occurs frequently, it will affect establishment and maintenance of bit synchronization, and a scrambling code is used in a transmitter, so as to avoid adverse effects of such data on receiver timing, and at the same time, in order to limit crosstalk caused by different degrees of non-linear characteristics existing in a circuit to other circuit communication, it is required that the minimum period of a digital signal is long enough, and it is sufficient to convert the digital signal into a digital sequence with statistical characteristics similar to white noise, which is usually implemented by scrambling, i.e. a technique of disturbing a signal without adding redundancy, changing the statistical characteristics of the digital signal to have statistical characteristics similar to white noise, so that in a wireless network of 802.11 standard, an AP transmits any frame to a STA including a scrambling code sequence with a total of 7 bits.
After the first device obtains the target TXOP through contention, the message is known by other devices contending for the channel together in a broadcast manner, so that the other devices take back-off measures. When the first device is to transmit a data frame with the second device, the first device shares the obtained target TXOP with the second device, and therefore, the first device configures first indication information in a scrambling sequence, where the first indication information is used to indicate that the second device shares the target TXOP obtained by the first device. Optionally, the first indication information is further used to indicate time information for the second device to communicate with the first device within the duration of the target TXOP, where the time information may include an absolute duration or a transmission period. As shown in fig. 2, a schematic diagram of a possible scrambling sequence provided in this embodiment of the present application is shown, where the scrambling sequence includes 7 bits, bit 1-bit 7, and the first device can carry the first indication information through bit1 and bit2, and in practical application, any continuous bit of the 7 bits can be selected to carry the first indication information, for example, the first indication information may occupy one bit of bits 1 to 7, or occupy multiple bits of bits 1 to bit7, and is not limited herein. Wherein bit1 and bit2 of the scrambling code sequence are used to indicate that the first device needs to share the target TXOP with the second device, and bits 3 to bit5 are used to inform the second device of the time information of the target TXOP, where the time information is an absolute time, for example, 001 may indicate that the second device performs backhaul every time it receives a data frame sent by the first device, and the transmission time of each time is at most 0.5 ms; 010 can indicate that the second device replies the data frame immediately after receiving the data frame sent by the first device, and the transmission duration of each time is at most 1 ms; when the time information is a transmission period, for example, 001 may indicate that the second device performs backhaul every time the second device receives a data frame sent by the first device; 010 may indicate that the second device performs backhaul every time it receives two data frames sent by the first device. It is understood that the meaning represented by the values of different bits or the combination of bits may be included in a preset table, and the preset table is pre-shared by the first device and the second device.
It should be noted that, configuring the first indication information in the scrambling sequence does not affect the original scrambling effect of the scrambling sequence.
103. A first device sends a frame containing a scrambling sequence to a second device;
after configuring the first indication information in the scrambling code sequence, the first device sends a frame containing the scrambling code sequence to the second device. The frame may be a CTS frame, an RTS frame, a control frame, or a data frame, and is not limited herein.
Optionally, the first device may broadcast a Beacon frame to notify other devices in the network that the first device has a target TXOP to share, so that the other devices in the network may acquire the Beacon by scanning to obtain the message, and the Beacon frame further includes a bitmap file (bitmap), and the device may obtain from the bitmap whether there is a message that needs to be received by itself, so that the second device may know that the message is sent to the device by the first device, that is, the second device knows that the first device needs to share the target TXOP with the first device. It should be noted that the bitmap in the beacon frame can only inform the second device that there is a message that needs to be received by the second device, and the time information of the target TXOP that the second device can use can only be known through the first indication information configured by the first device.
104. The second equipment confirms the first equipment to share the target TXOP according to the first indication information;
105. and the second equipment performs wireless communication with the first equipment within the time length of the target TXOP according to the time information.
After receiving the frame sent by the first device, the second device obtains the first indication information in the scrambling code sequence through decoding operation, confirms that the first device shares the target TXOP through the first indication information, and further obtains the absolute time length or the transmission period according to the time information indicated by the first indication information so as to communicate with the first device within the time length of the target TXOP.
It should be noted that, in practical applications, there may be a case where data transmission between the first device and the second device is not completed within the duration of the target TXOP. For example, after the first device sends a data frame to the second device, if the second device determines that the remaining duration of the target TXOP is less than the time that the second device needs to transmit the data frame, the second device does not send the data frame until the target TXOP is ended, the first device and the second device compete for the channel, the device contending for the channel first and then continue to transmit data, and similar operations from step 102 to step 105 may be performed again.
Optionally, in practical application, there is also a scenario that, for example, the first device sends a frame including a scrambling sequence to the second device to indicate that the second device shares the target TXOP, and if the first device does not receive a response message or a data frame of the second device within a preset time period after the first device sends a data frame to the second device, the first device may consider that the second device refuses to share the target TXOP. Or the first device determines that the second device has no Data to transmit, where the first device may determine whether the second device has Data to transmit according to a value of a MAC Protocol Data Unit (MPDU) in a MAC Data header transmitted by the second device, for example, assuming that the value of the MPDU may be 0 or 1, where 0 indicates that the second device has no Data to transmit and 1 indicates that the second device has Data to transmit, when the value of the MPDU is 0, the first device determines that the second device has no Data to transmit or the Data has been transmitted. In the similar scenario, the first device may send a notification message in the network, and clear a portion of the frame carrying the scrambling code sequence, which is used to indicate the time information, to notify other devices of a next TXOP to re-contend for the current channel, where the notification message may include a contention-free period end frame CF-end.
In the embodiment of the application, when the first device has a target TXOP, the first indication information is configured in the scrambling sequence in the frame sent to the second device to inform the second device to share the target TXOP, so that the first device and the second device can transmit the data frame within the duration of the target TXOP, and the service quality of the wireless network is improved.
