Description

Communication method, device, chip, user equipment and network equipment

Technical Field

The present application relates to scheduling technologies in wireless communication networks, and in particular, to a communication method, device, chip, user equipment, and network equipment.

Background

In wireless communication, it is important to schedule, for example, when the total power is unchanged, the larger the channel bandwidth is, the larger the amount of data to be transmitted is, the higher the transmission rate is, but the closer the transmission distance is, and the worse the interference resistance is. Therefore, in different channel scenarios, different channel bandwidths need to be adapted to achieve the optimal network transmission state.

Where the network environment is relatively simple, e.g., where there is no or relatively little interference in the vicinity of the network environment, faster data transmission speeds may be achieved using greater channel bandwidths. When the network environment is complex, for example, interference in the vicinity of the network environment is more, a better transmission effect can be obtained by using a lower channel bandwidth instead. Taking 802.11n as an example, the transmission rate which can be achieved under the bandwidth of 20MHz is 144Mbps, the penetrability is better, the transmission distance is far, and the transmission distance is about 100 meters; the transmission rate which can be achieved under the bandwidth of 40MHz is 300Mbps, but the penetrability is slightly poor, the transmission distance is about 50 meters, and the adjustment strategy of the channel bandwidth is important to the speed and the stability of wireless communication.

At present, the electronic equipment supports a multi-bandwidth mixed mode, the frequency band bandwidth of the electronic equipment is set to be a self-adaptive mode, in an automatic configuration mode, the electronic equipment negotiates a maximum bandwidth, the minimum bandwidth which can be supported by a receiving and transmitting end is used as an initial communication bandwidth, if the subsequent electronic equipment has other requirements for adjusting the bandwidth, the purpose of channel bandwidth switching is achieved by negotiating or disconnecting a reconnection mode with a network through an operation mode indication (Operating Mode Indication, OMI) mechanism, however, the switching efficiency of channel bandwidth switching by adopting the method is low, and the transmission efficiency is affected; as can be seen, the scheduling scheme employed in wireless communications is inefficient; it can be seen that the existing method for determining the scheduling parameters in the wireless communication network has the technical problem of low determination efficiency.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

An embodiment of the present application provides a communication method, where the method is applied to a communication system, fig. 1 is a schematic structural diagram of an alternative communication system provided by the embodiment of the present application, and as shown in fig. 1, the communication system 100 may include: a user device 11 and a network device 12.

Wherein, the user equipment 11 and the network equipment 12 are electronic devices in a wireless communication network, and the wireless communication network may be any one of the following networks: second generation mobile communication network technology (2nd Generation Mobile Communication Technology,2G) networks, third generation mobile communication network technology (3rd Generation Mobile Communication Technology,3G) networks, fourth generation mobile communication network technology (4th Generation Mobile Communication Technology,4G) networks, fifth generation mobile communication network technology (5th Generation Mobile Communication Technology,5G) networks, wireless fidelity (WIRELESS FIDELITY, wi-Fi) networks, bluetooth (BT) networks, zigBee (ZigBee) networks, wireless Mesh (Mesh) networks, and the like, to which embodiments of the present application are not particularly limited.

The user device 11 may be a smart phone, a tablet computer, a notebook computer, a wearable device, or the like, and is configured to communicate with the network device 12, for example, receive a command frame from the network device 12, so as to send a response frame to the network device 12; the network device 12 may be a router, a gateway, a wireless access Point (WIRELESS ACCESS Point, AP), a base station, a core network, etc. for communicating with the user device 11, and sending a command frame to the user device 11, so as to receive a response frame from the user device 11.

Based on the above communication system 100, fig. 2 is a schematic flow chart of an alternative communication method according to an embodiment of the present application, as shown in fig. 2, the communication method may include:

s201: the user equipment 11 determines a current channel quality parameter of the user equipment 11;

With the rapid advance of modern technology, more and more electronic devices are used In daily life, and In-device coexistence interference (In-Device Coexistence, IDC) is usually generated between different electronic devices, and the IDC can influence the sensitivity of a receiver of the electronic device, reduce the quality of signals and cause data loss In severe cases. Taking the scheduling parameter as the channel bandwidth as an example, in the wireless communication network, when the performance of the electronic device is found to be poor, the channel bandwidth is switched by using a mode that the electronic device disconnects from reconnection, and the switching efficiency of the mode is low. In addition, because the physical locations of the electronic devices are closely spaced and operate in the same or adjacent frequency ranges, it may be necessary to turn off nearby electronic devices to ensure proper operation of the electronic devices. In addition, not all electronic devices support the OMI scheduling mechanism, and at this time, the electronic devices can only switch the bandwidth by disconnecting reconnection, which greatly affects the transmission efficiency.

In order to improve the efficiency of determining the scheduling parameters in the wireless communication network and to perform scheduling in time to ensure the transmission performance of the user equipment 11, in the embodiment of the present application, the network equipment 12 sends a command frame to the user equipment 11, and then the user equipment 11 needs to respond to the command frame sent by the network equipment 12, that is, the user equipment 11 needs to send a response frame to the network equipment 12, where, in order to obtain the response frame, the user equipment 11 needs to determine, in addition to acquiring the content of each field of the response frame, the current channel quality parameter of the user equipment 11, where the channel quality parameter may include: signal Power, throughput, error vector magnitude (Error Vector Magnitude, EVM), received Power of reference signal (REFERENCE SIGNAL RECEIVING Power, RSRP), signal-to-noise ratio (Signal Noise Ratio, SINR), received Quality of reference signal (REFERENCE SIGNAL RECEIVING Quality, RSRQ), channel Quality indication (Channel Quality Indicator, CQI), etc., as embodiments of the application are not limited in this regard.

In this way, the current channel quality parameter of the user equipment 11 is determined.

S202: the user equipment 11 writes the current channel quality parameter of the user equipment 11 into a reserved field of the response frame;

After determining the current channel quality parameter of the ue 11 in S201, the current channel quality parameter of the ue 11 is written into the response frame, where after determining each field of the response frame, the current channel quality parameter of the ue 11 is written into the reserved field of the response frame, so that the response frame including the current channel quality parameter of the ue 11 is determined.

It will be appreciated that the current channel quality parameter of the user equipment 11 may be represented by a binary number as a reserved field in the response frame; the maximum channel bandwidths of the ue 11 may be grouped first, then each group of channel bandwidths is classified by a preset channel quality threshold, and then the current channel quality parameters of each group of channel bandwidths are represented in a binary manner according to the classification result, so that the current channel quality parameters of the ue 11 may be determined.

S203: the user equipment 11 transmits a response frame to the network equipment 12;

S204: the network device 12 determines a target scheduling parameter for the user device 11 in the wireless communication network based on the current channel quality parameter of the user device 11.

After the current channel quality parameter of the ue 11 is written in the response frame through S202, the ue 11 sends the response frame to the network device 12, so that the network device 12 can receive the current channel quality parameter of the ue 11, and further determine a target scheduling parameter for the ue 11 in the wireless communication network according to the current channel quality parameter of the ue 11.

The target scheduling parameter may be a channel bandwidth, a modulation and coding parameter, or any other scheduling parameter, which is not limited in the embodiment of the present application.

In this way, the determination efficiency of the scheduling parameters in the wireless communication network is improved, so that the scheduling efficiency is improved, and the transmission performance of the user equipment 11 is ensured.

In an alternative embodiment, for the current channel quality parameter of the ue 11, the current channel quality parameter of the ue 11 includes channel puncturing information, where the channel puncturing information is used to indicate whether at least one 20MHz channel is occupied.

It will be appreciated that the current channel quality of the ue 11 includes channel puncturing information for indicating whether at least one 20MHz channel is occupied, so that after receiving the response frame, the network device 12 can acquire the channel puncturing information in the current channel quality parameter of the ue 11 from the reserved field of the response frame, so as to know whether the at least one 20MHz channel is occupied.

On the basis of knowing whether at least one 20MHz channel is occupied, the network device 12 may perform downlink scheduling, including determining the channel bandwidth of the user device 11 based thereon.

For the channel puncturing information included in the current channel quality parameter for device 11, in an alternative embodiment, the channel puncturing information corresponds to at least one bit in the reserved field, the bit value of the bit indicating whether the error vector magnitude EVM of the corresponding 20MHz channel is below a preset threshold.

It may be appreciated that the channel puncturing information may correspond to one bit in the reserved field, may correspond to a plurality of bits in the reserved field, and may correspond to all bits in the reserved field, which is not specifically limited herein.

Then, for the bit in the reserved field corresponding to the channel puncturing information, the bit value may indicate whether the EVM of the 20MHz channel is lower than the preset threshold, that is, the bit value is determined by the magnitude relation between the EVM of the 20MHz channel and the preset threshold, for example, when the EVM of the 20MHz channel is greater than the preset threshold, the bit value is 1, the EVM of the 20MHz channel is less than the preset threshold, and the bit value is 0.

Taking the example of the wireless communication network being a Wi-Fi network, in an alternative embodiment, the response frame includes any one of:

BA frames, ACK frames, and CTS frames.

As can be appreciated, in the Wi-Fi network, when the network device 12 sends a Request To Send (RTS) frame to the user device 11, the user device 11 sends a response frame, that is, a Clear To Send (CTS) frame, to the network device 12; when the network device 12 sends an add block acknowledgement Request (add block Acknowledgment Request, ADDBA Request) to the user device 11, the user device 11 sends a response frame, i.e., an Acknowledgement (ACK) frame, to the network device 12; when the network device 12 transmits a block acknowledgement request (BlockAck req) frame to the user device 11, the user device 11 transmits a response frame, that is, a Block Acknowledgement (BA) frame, to the network device 12.

Thus, for the wireless communication network formed by the Wi-Fi network, the response frame may be any one of the BA frame, the ACK frame and the CTS frame, and the current channel quality parameter of the user equipment 11 is written into the reserved field in any one of the BA frame, the ACK frame and the CTS frame, so that the user equipment 11 is prevented from being scheduled by adopting a special frame, the determination efficiency of the scheduling parameter in the wireless communication network is improved, the scheduling efficiency is further improved, and the transmission performance of the user equipment 11 is ensured.

For the above-mentioned target scheduling parameter being a channel bandwidth, in order for the ue 11 to determine the current channel quality parameter of the ue 11, in an alternative embodiment, when the target scheduling parameter is the channel bandwidth, the determining, by the ue 11, the current channel quality parameter of the ue 11 may include:

the user equipment 11 determines a bandwidth granularity for the maximum channel bandwidth that the user equipment 11 can allocate;

the user equipment 11 determines a current channel quality parameter at each bandwidth granularity;

The user equipment 11 determines the current channel quality parameter at each bandwidth granularity as the current channel quality parameter of the user equipment 11.

It will be appreciated that after receiving the command frame, the ue 11 determines a response frame, in which, in order to write the current channel quality parameter of the ue 11 into the response frame, the ue 11 determines a bandwidth granularity of the maximum channel bandwidth allocable to the ue 11, for example, 320M for the maximum channel bandwidth allocable to the ue 11, 20M for the maximum channel bandwidth allocable to the ue 11, and of course, 5M for the bandwidth granularity, where the ue 11 may determine the bandwidth granularity according to the specific situation of the ue 11.

After determining the bandwidth granularity of the maximum channel bandwidth allocable to the user equipment 11, the user equipment 11 determines a current channel quality parameter at each bandwidth granularity, where, taking the allocable maximum channel bandwidth as 320M and the bandwidth granularity as 20M as an example, the current channel quality parameter at each 20M may be determined, and finally, the user equipment 11 determines the current channel quality parameter at each bandwidth granularity as the current channel quality parameter of the user equipment 11.

Thus, the bandwidth granularity is determined, so that the current channel quality parameter at each bandwidth granularity is determined as the current channel quality parameter of the user equipment 11.

Further, to determine the bandwidth granularity, in an alternative embodiment, the determining, by the user equipment 11, the bandwidth granularity of the maximum channel bandwidth allocable to the user equipment 11 may include:

The user equipment 11 determines the bandwidth granularity based on the current signal strength of the user equipment 11 and the processing capability parameters of the user equipment 11.

It may be appreciated that, in determining the bandwidth granularity, the ue 11 first obtains the current signal strength of the ue 11 and obtains the processing capability parameter of the ue 11, where, for example, the processing capability parameter of the ue 11 may be the number of bytes of the reserved field of the response frame, or may be the data width that can be processed by the Wi-Fi chip, for example, 64 bits, or 32 bits.

After the current signal strength of the user equipment 11 and the processing capability parameter of the user equipment 11 are obtained, the user equipment determines the bandwidth granularity based on the current signal strength of the user equipment 11 and the processing capability parameter of the user equipment 11, where a preset correspondence may be adopted to determine the bandwidth granularity corresponding to the current signal strength of the user equipment 11 and the processing capability parameter of the user equipment 11, and a trained neural network model may also be adopted to determine the bandwidth granularity, where embodiments of the present application are not limited in this way.

Wherein in determining the bandwidth granularity, in an alternative embodiment, the current channel strength of the user equipment 11 is positively correlated with the bandwidth granularity; the processing capability parameter of the user equipment 11 is positively correlated with the bandwidth granularity.

It will be appreciated that, since the current signal strength of the ue 11 is positively correlated with the bandwidth granularity, the processing capability parameter of the ue 11 is corrected with the bandwidth granularity, so that it can be obtained that the stronger the current signal strength of the ue 11, the larger the bandwidth granularity, the weaker the current signal strength of the ue 11, the smaller the bandwidth granularity, and the smaller the processing capability parameter of the ue 11, the larger the bandwidth granularity, the larger the processing capability parameter of the ue 11, and the smaller the bandwidth granularity.

Taking the above-mentioned processing capability parameter of the ue 11 as an example of the number of bytes in the reserved field of the response frame, when the allocable maximum bandwidth is 320M, if the reserved field is 2 bytes, the bandwidth granularity is minimum 20M, and if the reserved field is at least 8 bytes, the bandwidth granularity is minimum 5M.

Thus, the bandwidth granularity can be determined.

After determining the bandwidth granularity, in order to determine the current channel quality parameter at each bandwidth granularity, in an alternative embodiment, the determining, by the user equipment 11, the current channel quality parameter at each bandwidth granularity may include:

the user equipment 11 calculates EVM at each bandwidth granularity;

the user equipment 11 determines a current channel quality parameter at a bandwidth granularity of which the EVM is greater than a preset threshold value as a first bit value;

The user equipment 11 determines the current channel quality parameter at a bandwidth granularity where the EVM is less than a preset threshold as the second bit value.

It may be understood that, the user equipment 11 calculates the EVM at each bandwidth granularity, for example, the maximum channel bandwidth that can be allocated is 320M, and the bandwidth granularity is 20M, and for example, the EVM at each 20M is calculated, a preset threshold is stored in the user equipment 11, the calculated EVM at each bandwidth granularity is compared with the preset threshold, the current quality parameter at the bandwidth granularity where the EVM is greater than the preset threshold is determined as a first bit value, that is, the current channel quality parameter at the bandwidth granularity where the channel quality is better is represented by a first bit value, the current quality parameter at the bandwidth granularity where the EVM is less than the preset threshold is determined as a second bit value, that is, the current quality parameter at the bandwidth granularity where the channel quality is worse is represented by a second bit value, and the current quality parameter at the bandwidth granularity where the EVM is equal to the preset threshold may also be represented by a second bit value.

Wherein, the first bit value may be 1, and the second bit value may be 0.

Thus, the current channel quality parameter of the user equipment 11 can be determined, written into the response frame and sent to the network equipment 12, the scheduling parameter can be determined in time, the user equipment 11 can be scheduled in time, and the transmission performance of the user equipment 11 is ensured.

For the case where the target scheduling parameter is the channel bandwidth, in an alternative embodiment, when the response frame is a BA frame or an ACK frame, the sending, by the user equipment 11, the response frame to the network equipment 12 in the wireless communication network may include:

The user equipment 11 determines the current channel quality parameter of the user equipment 11 after receiving one or more data frames during the TXOP time.

It will be appreciated that when the network device 12 sends an RTS to the user device 11, the user device 11 sends a CTS to the network device 12, causing the user device 11 to turn on the TXOP time.

In the TXOP time, if the response frame is a BA frame or an ACK frame, the network device 12 sends the data frame to the user device 11, so that the user device 11 may receive one data frame, where after receiving one data frame, the user device 11 may receive a command frame from the network device 12, send the response frame to the network device 12, or the user device 11 may receive the command frame from the network device 12 after receiving multiple data frames, send the response frame to the network device 12, where the response frame may be an ACK frame or a BA frame, that is, the user device 11 may send the response frame after receiving one data frame to report the current channel quality parameter of the user device 11, or may send the response frame after receiving multiple data frames to report the current quality parameter of the user device 11, thereby performing scheduling on the user device 11 in different frequencies, and further improving the scheduling efficiency and ensuring the transmission performance of the user device 11.

In addition, for the case that the target scheduling parameter is a modulation and coding parameter, in order for the network device 12 to determine the target scheduling parameter for the user device 11 in the wireless communication network, in an alternative embodiment, when the target scheduling parameter is the modulation and coding parameter, the determining, by the network device 12, the target scheduling parameter for the user device 11 in the wireless communication network according to the current channel quality parameter of the user device 11 may include:

The network device 12 determines the scheduling parameter corresponding to the current channel quality parameter of the user device 11 as a modulation and coding parameter for the user device 11 in the wireless communication network based on the correspondence between the channel quality parameter and the scheduling parameter.

It may be appreciated that the corresponding relationship between the channel quality parameter and the scheduling parameter is stored in the network device 12, and based on the corresponding relationship, the scheduling parameter corresponding to the current channel quality parameter of the user device 11 may be determined, and then the scheduling parameter corresponding to the current channel quality parameter of the user device 11 is determined as the modulation and coding parameter for the user device 11 in the wireless communication network.

The current channel quality parameter of the ue 11 may be a throughput rate of the ue 11. Of course, other channel quality parameters are also possible, and embodiments of the present application are not limited in this regard.

Further, in order to schedule the user equipment 11 in time, in an alternative embodiment, the method may further include:

when the determined modulation and coding parameters and the current modulation and coding parameters are different, the network device 12 updates the current modulation and coding parameters to the determined modulation and coding parameters.

It will be appreciated that after determining the modulation and coding parameters, the network device 12 compares the determined modulation and coding parameters with the current modulation and coding parameters of the user device 11 stored in the network device 12, and if the determined modulation and coding parameters are the same as the current modulation and coding parameters, it indicates that the current modulation and coding parameters are applicable to the current state of the user device 11, so the current modulation and coding parameters are not updated, and if the determined modulation and coding parameters are different from the current modulation and coding parameters, it indicates that the current modulation and coding parameters are not applicable to the current state of the user device 11, so the current modulation and coding parameters are updated to the determined modulation and coding parameters, so that the user device 11 can be timely scheduled, thereby ensuring the transmission performance of the user device 11 in the wireless communication network.

For the case that the target scheduling parameter is a channel bandwidth, in order for the network device 12 to determine the target scheduling parameter for the user device 11 in the wireless communication network, in an alternative embodiment, when the target scheduling parameter is the channel bandwidth parameter, the determining, by the network device 12, the target scheduling parameter for the user device 11 in the wireless communication network according to the current channel quality parameter of the user device 11 may include:

the network device 12 determines available channel bandwidth parameters according to the current channel quality parameters of each bandwidth granularity in the current channel quality parameters of the user device 11;

the network device 12 selects a channel bandwidth parameter corresponding to a positive number, which has the smallest difference value of the available channel bandwidth parameters, from among channel bandwidth parameters supportable in the wireless transmission standard protocol based on the available channel bandwidth parameters;

The network device 12 determines the selected channel bandwidth parameter as the channel bandwidth parameter for the user device 11 in the wireless communication network.

Here, unlike the target scheduling parameter being a modulation and coding parameter, in determining the channel bandwidth for the user equipment 11 in the wireless communication network, the channel bandwidth parameter for the user equipment 11 in the wireless communication network should be determined as one of the channel bandwidth parameters supportable in the wireless transmission standard protocol, taking into account the channel bandwidth parameters supportable in the wireless transmission standard protocol.

It can be understood that the network device 11 knows which channel quality is better and which channel quality is worse according to the current channel quality parameter of each bandwidth granularity in the current channel quality parameters of the user device 11, so as to determine the available channel bandwidth parameter, where the available channel bandwidth parameter is a channel with better channel quality determined according to the channel quality parameter.

After determining the available channel bandwidth parameters, the network device 12 makes a difference between the available channel bandwidth parameters and the channel bandwidth parameters supportable in the wireless transmission standard to obtain a difference value, and selects the channel bandwidth parameter corresponding to the smallest positive number in the difference value, and determines the channel bandwidth parameter as the channel bandwidth parameter for the user device 11 in the wireless communication network, so that when the available channel bandwidth parameter does not exist in the supportable channel bandwidth parameters, the maximum value smaller than the available channel bandwidth parameter is selected as the channel bandwidth parameter for the user device 11 in the wireless communication network.

In this way, the channel bandwidth supported by the wireless transmission standard protocol can be determined as the channel bandwidth parameter for the user equipment 11 in the wireless communication network based on the current channel quality parameter of the user equipment 11, which is beneficial to the scheduling of the user equipment 11.

To determine the available channel bandwidth parameters, in an alternative embodiment, the network device 12 determines the available channel bandwidth parameters based on the current channel quality parameters at each bandwidth granularity among the current channel quality parameters of the user device may include:

The network device 12 determines the current channel quality parameter at the bandwidth granularity as the sum of the bandwidth granularities corresponding to the first bit values as the available channel bandwidth parameter.

It can be understood that, since the current channel quality parameter under the bandwidth granularity can reflect the channel quality under the bandwidth granularity, when the current channel quality parameter under the bandwidth granularity is the first bit value, it is indicated that the current channel quality under the bandwidth granularity is better, in order to improve the transmission performance of the user equipment, the network equipment 12 uses the sum of the bandwidth granularities corresponding to the first bit value as the available channel bandwidth parameter, and thus, the determined available channel bandwidth parameter is a parameter that is beneficial to improving the transmission performance of the user equipment 11, and further is beneficial to improving the scheduling efficiency and the transmission performance.

when the determined channel bandwidth parameter is different from the current channel bandwidth parameter, the network device 12 updates the current channel bandwidth parameter to the determined channel bandwidth parameter.

It will be appreciated that after determining the channel bandwidth parameter, the network device 12 compares the determined channel bandwidth parameter with the current channel bandwidth parameter of the user device 11 stored in the network device 12, if the determined channel bandwidth parameter is the same as the current channel bandwidth parameter, it indicates that the current channel bandwidth parameter is suitable for the current state of the user device 11, so that the current channel bandwidth parameter is not updated, and if the determined channel bandwidth parameter is different from the current channel bandwidth, it indicates that the current channel bandwidth parameter is not suitable for the current state of the user device 11, so that the current channel bandwidth parameter is updated to the determined channel bandwidth parameter, so that the user device 11 can be scheduled in time, thereby ensuring the transmission performance of the user device 11 in the wireless communication network.

The communication methods described in one or more of the above embodiments are described below by way of example.

Taking a wireless communication network as a Wi-Fi network as an example, fig. 3 is a schematic flow interaction diagram of an example of an alternative communication method provided by the embodiment of the present application, as shown in fig. 3, where a sending end is a network device, and a receiving end is a user device, and the communication method may include:

S301: the transmitting end transmits an ADDBA Request (Request) to the receiving end;

s302: the receiving end sends an ACK frame to the sending end;

In S301 to S302, the transmitting end sends an RTS frame to the receiving end, the receiving end sends a CTS frame to the transmitting end, so that the transmitting end sends an ADDBA Request to the receiving end in the TXOP time when the TXOP time is started, and receives an ACK frame fed back by the receiving end.

S303: the receiving end sends an ADDBA Response (Response) to the sending end;

S304: the sending end sends an ACK frame to the receiving end;

in S303 to S304, the receiving end transmits an ADDBA Response to the transmitting end, and receives an ACK frame fed back by the receiving end.

S305: a transmitting end transmits a quality of service Data (Quality of Service, qos Data) message protocol Data unit (Message Protocol Data Unit, MPDU) to a receiving end;

s306: the transmitting end transmits a BlockAck Req to the receiving end;

s307: the receiving end sends a BlockAck frame to the sending end.

In S305 to S307, the transmitting end may send one Qos Data MPDU to the receiving end, or may send a plurality of Qos Data MPDUs to the receiving end, after that, the transmitting end sends a BlockAck Req to the receiving end, and the receiving end receives the BlockAck Req and needs to determine a BlockAck frame, where in determining the BlockAck frame, the bandwidth granularity of the receiving end is determined first, where based on the current signal strength and the processing capability parameter of the receiving end, an appropriate bandwidth granularity may be selected, and then the EVM under each bandwidth granularity is calculated, so that according to the relation between the calculated EVM and the preset threshold, the current channel quality parameter under each bandwidth granularity is determined, and the current channel quality parameter under each bandwidth granularity is determined as the current channel quality parameter (punctureInfo) of the receiving end, and is written into a reserved field in the BlockAck frame, thereby forming the BlockAck frame, and is sent to the transmitting end.

For the structure of the BlockAck frame, fig. 4 is a schematic structural diagram of an example of an optional BA frame provided by the embodiment of the present application, where, as shown in fig. 4, the BlockAck frame may include: a Header (Medium, access, control Header, MAC HEADER) of the media intervention Control, a Control field (BA Control) of the BA frame, a Control field (BA Starting Sequence Control) of a start Sequence of the BA frame, a Bitmap (BA Bitmap) of the BA frame, puncture information (punctureInfo), and a frame check Sequence (FRAME CHECK Sequence, FCS).

In some embodiments, punctureInfo is used to store the current channel quality parameter of the receiving end, punctureInfo may store CQIs of one or more 20MHz channels (or 10MHz, 5MHz channels), or indicate whether the corresponding error vector magnitude EVM of one or more 20MHz channels (or 10MHz, 5 MHz) is below a preset threshold. In other embodiments punctureInfo is channel puncturing information, which may indicate whether one or more of the 20MHz channels (or 10MHz, 5 MHz) are occupied.

The present example uses BA frame feedback to carry punctureInfo of Bandwidth (BW) information, so as to achieve the purpose of fast switching bandwidth. The BA frame usually works in the TXOP mode, and is usually started for a period of time of TXOP with RTS/CTS, and then starts to send data frames, where the mode can reply to the frame one by one with an ACK frame or a BA frame in a period of transmission time, and the frame format of the BA frame is shown in fig. 4, where punctureInfo field is an added field, and occupies a width of two bytes or more.

In some embodiments, punctureInfo field is reserved as a special field in the response frame, where the field may store channel puncturing information, and when the response frame is sent, the sender (e.g., user equipment) of the response frame writes the channel puncturing information in the field to indicate the current channel occupancy of the receiver (e.g., network equipment) of the response frame; after receiving the response frame, the network device may perform downlink scheduling according to the occupation condition of the channel, including selecting an MCS parameter, determining an available frequency band, and the like.

There may be various algorithms to determine the content (e.g., bit values) of the punctureInfo field, such as may be derived in the frequency domain using the EVM information of the subcarriers. Taking two bytes as an example, when 320M bandwidth is supported maximally, punctureInfo can be fed back according to 20M as minimum granularity, punctureInfo corresponds to the situation that each 20M is occupied, the channel quality parameter corresponding to the EVM of the 20M channel bandwidth with the EVM larger than the preset threshold is set to 0,0 represents that the 20M channel quality is better, the sending end can select to send a signal on the 20M, the channel quality parameter corresponding to the EVM of the 20M channel bandwidth with the EVM smaller than or equal to the preset threshold is set to 1,1 represents that the 20M channel quality is worse, the sending end can not send a signal on the 20M, and other setting modes can also be provided that the sending end negotiates and can resolve correctly.

On the other hand, in order to support more accurate bandwidth information, the granularity of the feedback can be set smaller, for example, 5M or 10M is used as granularity feedback punctureInfo, the smaller granularity is the more accurate the interference detection, the more accurate the analyzed bandwidth information is, but the influence is that the number of bytes fed back is increased, the 5M granularity under 320M bandwidth needs eight bytes, which is 4 times of the number of bytes with 20M granularity. Compared with the bandwidth switching algorithm in the related art, the bandwidth feedback information is obtained by using a small amount of byte obtaining information in the BA frame, and the closed loop flow of the bandwidth switching of the equipment is completed. The receiving end may select an appropriate granularity calculation punctureInfo according to the network environment state (for example, the current signal strength) of the device and the hardware resource condition (the number of bytes of the reserved field or the width of the processing data of the processing chip) of the device, and fill the calculated punctureInfo into the corresponding field of the BA frame, and feed back to the transmitting end for adjusting the transmission bandwidth thereof multiple times in a period of TXOP transmission time.

When the wireless sources are fewer in the current environment, the interference to signals in the frequency band bandwidth is fewer, the channels are relatively clean, the number of 0 in punctureInfo fed back by the receiving end under the initial bandwidth is more, the maximum channel bandwidth which can be sent by the equipment in the current state can be calculated by analyzing the number of 0. Otherwise, when the channel quality is poor, the number of 1 in punctureInfo fed back by the receiving end is more, and the bandwidth of the channel which can be sent by analysis is reduced.

In this way, the corresponding bandwidth information can be obtained through analysis through punctureInfo in the BA frame, so that the optimal working bandwidth of the current equipment is calculated, the information is fed back to the sending end, and the sending end adjusts the bandwidth in real time according to punctureInfo, so that the maximum working efficiency of the receiving end equipment is ensured; the process fully plays the importance of feedback, has the capacity of suppressing interference, and enables the correction action of the channel bandwidth to be more accurate and powerful.

In S305 to S307, the transmitting end may send one Qos Data MPDU to the receiving end, or may send a plurality of Qos Data MPDUs to the receiving end, and after the sending is completed, the transmitting end sends a BlockAck Req to the receiving end, and the receiving end sends a BlockAck frame to the transmitting end, where the receiving end feeds back the BlockAck frame to the transmitting end, which may be immediate feedback or delayed feedback.

For immediate feedback, fig. 5a is a timing diagram of an example one of an alternative communication method provided by the embodiment of the present application, where, as shown in fig. 5a, a transmitting end sends a BAR after sending three Qos Data, and a receiving end sends a BA frame after an interval.

For delay feedback, fig. 5b is a timing diagram of an example two of an alternative communication method provided by the embodiment of the present application, where, as shown in fig. 5b, a sending end sends a block acknowledgement request (block acknowledgment request, BAR) after sending three Qos Data, after an interval time, a receiving end sends an ACK frame, and after the interval time, the receiving end sends a BA frame, and the receiving end sends an ACK frame.

In addition, the example may select to feed back another parameter to implement scheduling, for example, the current channel quality parameter is added to the response frame, and the opposite end schedules the modulation and coding strategy (Modulation and Coding Scheme, MCS) parameter (equivalent to the modulation and coding parameter described above) through the information in the response frame. Meanwhile, here, the response frame includes, but is not limited to, a BA frame, an ACK frame, and a CTS frame.

In summary, the present example is used for scheduling the channel bandwidth by feeding punctureInfo the response frame back to the opposite end, and the throughput performance is better than the non-response frame feedback algorithm under different channel conditions, so that the throughput performance and the utilization rate of the network can be effectively improved.

In order to solve the problem of slow channel bandwidth negotiation rate in the downlink scheduling process, based on punctureInfo to the opposite end of the BA frame feedback carrying bandwidth information, the field can select proper granularity in combination with the interference condition of the current frame at the receiving end, the opposite end can use the information to determine the channel bandwidth of the next packet, and the downlink scheduling can be timely adjusted for a plurality of times in one TXOP, so that the convergence rate of throughput is improved.
