The realization, functional characteristics and advantages of the purpose of the present application will be further described with reference to the accompanying drawings in conjunction with the embodiments. Specific embodiments of the present application have been shown by the above-mentioned drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concepts of the present application in any way, but to illustrate the concepts of the present application to those skilled in the art by referring to specific embodiments.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

First, the terms involved in the embodiments of the present application are explained:

SINR: refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference), which can be simply understood as "signal-to-noise ratio".

The RTS/CTS protocol, that is, the request to send/allow to send protocol, is equivalent to a handshake protocol and is mainly used to solve the "Hidden Stations" problem. A "hidden site" is one that is too far away to detect the presence of a media competitor. For example, base station A sends data to terminal equipment B, but base station C does not detect that base station A sends data to terminal equipment B. Therefore, base station A and base station C simultaneously send data to terminal equipment B, causing signal conflict and eventually data transmission failure. . "Hidden sites" often occur in large cells (usually in outdoor environments), which incur efficiency losses and require error recovery mechanisms. When large-capacity files need to be transferred, it is especially necessary to prevent the occurrence of the phenomenon of "hidden sites". IEEE802.11 provides the following solution: In the parameter configuration, if the RTS/CTS protocol is used, the upper limit of the number of bytes to be transmitted is set at the same time. Once the data to be transmitted is greater than the upper limit, the RTS/CTS protocol is activated:

First, base station A sends RTS to terminal equipment B through a beam, indicating that base station A wants to send data to terminal equipment B. After receiving the RTS, terminal equipment B sends CTS to all base stations, indicating that it is ready, and base station A can send data to Terminal equipment B, other base stations temporarily do not send data to terminal equipment B, that is, the remaining base stations remain silent for a period of time; then, base station A sends data to terminal equipment B; after terminal equipment B receives the data, it broadcasts ACK to all base stations ( Acknowledge character, confirmation character) to confirm the frame, so that all base stations can listen to and compete for the channel equally again.

For now, continuous evolution to high frequency is an important means for 5G (5th Generation mobile networks or 5th Generation wireless systems, 5th-Generation, fifth-generation mobile communication technology) systems to continue to improve system capacity. During the formulation of the latest R17 standard, extending the existing 5G system to 52GHz to 71GHz is an important topic. Since some sub-bands belong to unlicensed frequency bands according to different countries and regions in the 52GHz-71GHz frequency band, the first problem to be solved is the coexistence of the 5G system and other wireless access networks (such as WIFI). In view of the coexistence problem, in the existing LTE system, the LBT function using LAA has been used.

Since the 52GHz-71GHz frequency band belongs to the high frequency band, the energy of the transmitting beam is highly concentrated and the coverage is narrow, so the LBT function similar to LTE-LAA cannot adapt to the high frequency band.

Based on the above problems, the present application provides a processing method, device, system and storage medium for improving system capacity. When the current beam has interference, other non-interfering beams are used for data transmission without waiting for the interference on the current beam. End retransmission of data to increase system capacity. Optionally, when the network device and the terminal device handshake based on the RTS/CTS protocol, the RTS is sent through at least two beams.

Of course, in other scenarios, the first base station and the second base station may also have independent AMFs/UPFs, which are not limited in this embodiment of the present application.

Before the base station sends data, it needs to determine the beam used for data transmission. Determine the target beam used for transmitting data" from the at least two candidate beams, thereby completing the download.

The technical solutions of the embodiments of the present application and how the technical solutions of the present application solve the above-mentioned technical problems will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the embodiments of the present application will be described below with reference to the accompanying drawings.

FIG. 2 is a schematic diagram of signaling interaction of a processing method provided by an embodiment of the present application. The embodiment of the present application provides a processing method, which is applied to the above-mentioned network device and terminal device. As shown in Figure 2, the processing method of this embodiment includes the following steps:

S10. Send RTS on at least two candidate beams to obtain corresponding CTS.

In order to increase the system capacity, the embodiment of the present application uses at least two candidate beams during handshake based on the RTS/CTS protocol. In this way, even if there is interference on some of the at least two candidate beams, other candidate beams without interference can be determined as target beams at this time.

In an implementation scenario, when the network device has data to transmit to the terminal device, the network device executes step S10. Optionally, reference may be made to subsequent embodiments for the determination of candidate beams. For example, referring to FIG. 3 , based on 3 candidate beams, the network device sends RTS to the terminal device, and each candidate beam transmits one RTS.

Optionally, the RTS corresponding to different candidate beams may be the same, that is, the same RTS is sent on candidate beam 1 and candidate beam 2; or, the RTS corresponding to different candidate beams may also be different, as shown in FIG. 4 . For example, the RTSs sent through the N candidate beams are respectively: RTS ₀ , RTS ₁ , RTS ₂ , RTS ₃ , . . . , RTS _N-1 , where N is a positive integer greater than or equal to 2.

Optionally, the terminal device receives the RTS on at least one candidate beam, and performs step S20. Considering that there may be interference on the at least two candidate beams, the terminal device may not be able to receive all the RTS. For example, the network device sends RTS to the terminal device in 5 candidate beams, and the terminal device only uses 4 or less of them. RTS is received on the candidate beam.

S20. In response to the RTS received on the at least one candidate beam, generate or determine a CTS corresponding to the RTS.

Optionally, the CTS is used to instruct the network device to determine a target beam for transmitting data based on the candidate beam used by the CTS.

Optionally, the terminal device generates or determines a CTS corresponding to the RTS in response to the RTS received on the at least one candidate beam. As for the specific manner in which the terminal device generates or determines the CTS, reference may be made to the related art, which will not be repeated here. After that, the terminal device executes step S30.

S30. Send the CTS on the corresponding candidate beam.

Optionally, the CTS corresponding to the transmission is the same as the candidate beam used by the RTS.

For example, referring to FIG. 5 , based on 3 candidate beams, the terminal device sends CTS to the network device, and each candidate beam transmits one CTS.

Optionally, the CTS corresponding to different candidate beams may be the same, that is, the same CTS is sent on candidate beam 1 and candidate beam 2; or, the CTS corresponding to different candidate beams may also be different, as shown in FIG. 6 . Example, corresponding to Figure 4. The CTSs sent by the terminal equipment through the N-2 candidate beams are respectively: CTS ₀ , CTS ₂ , CTS ₃ , ..., CTS _N-1 . In the example shown in FIG. 6 , the terminal device does not receive the RTS ₁ sent by the network device, and other RTSs are deemed to be received normally.

Optionally, the network device receives the CTS. Similarly, considering that there may be interference on the beam, the number of CTSs received by the network device may be less than the number of CTSs sent by the terminal device. As shown in Figure 6, the network device has not received the CTS sent by the terminal device. ₀ , other CTSs are regarded as receiving normal.

Next, the network device executes step S40.

In this step, the network device determines a candidate beam for transmitting CTS based on the received CTS, and determines a target beam used for transmitting data from the candidate beams for transmitting CTS according to a preset rule. Optionally, the candidate beam for transmitting the CTS is a beam among the at least two candidate beams as described above.

In an implementation manner, the network device determines a target beam used for transmitting data from at least two candidate beams according to a preset rule, which may include: among the candidate beams receiving the CTS, determining that the candidate beam with the best beam quality is for transmission. The target beam used for the data. Optionally, it can be indicated that the quality of the beam is good from multiple angles, for example, the value of the measurement parameter is high. Optionally, the measurement parameter may be at least one of RSRP, RSRQ and SINR.

It should be noted that, based on the RTS/CTS protocol, the success probability of determining the target beam used for data transmission in at least two candidate beams is significantly higher than the success probability of determining a beam as the target beam used for data transmission. Therefore, The embodiments of the present application can improve the system capacity.

Optionally, CTS is directional, corresponding to RTS. That is to say, even if the network device that does not send the corresponding RTS receives the CTS, it will temporarily not send data to the above-mentioned terminal device, that is, the remaining network devices remain silent for a period of time.

In this embodiment of the present application, the network device sends the RTS to the terminal device on at least two candidate beams to obtain the corresponding CTS, and based on the CTS, determines the target beam used for data transmission from the at least two candidate beams according to preset rules. Since the network device sends the RTS to the terminal device through at least two candidate beams, and determines the target beam used for data transmission from the at least two candidate beams, when one of the candidate beams has interference, other non-interfering beams can also be used. The candidate beams are used for data transmission, so the system capacity can be improved.

Optionally, if the RTS is encoded with a fixed RTS code BR (Bit Rate, code rate) and then sent, this design can only indicate whether there is interference in the connection of the current beam under the fixed RTS code rate, and also There may be the possibility that other non-interfering beams can communicate using a higher RTS code rate. Therefore, considering that the beam quality of different candidate beams may be different, different candidate beams may use different RTS coding code rates. That is, in the above at least two candidate beams, the RTS coding code rates corresponding to different candidate beams are different. For example, still referring to FIG. 4 , the RTS encoding code rate corresponding to RTS ₀ is BR ₀ , the RTS encoding code rate corresponding to RTS ₁ is BR ₁ , and so on.

Optionally, the RTS carries information indicating the RTS encoding rate, for example, the RTS carries a specific RTS encoding rate; or, the RTS carries information that implicitly indicates the RTS encoding rate, for example, the RTS carries a unique identifier, the The unique identifier is used to indicate the RTS coding rate, etc., to inform the terminal equipment. Optionally, the CTS adopts the same RTS coding rate as the corresponding RTS.

Based on the above, in another implementation manner, determining a target beam used for transmitting data from at least two candidate beams according to a preset rule may include: determining a corresponding RTS encoding code rate among the candidate beams that receive the CTS. The highest candidate beam is the target beam used to transmit data.

Optionally, since the higher the RTS coding rate is, the lower the tolerance of RTS to interference is. Therefore, the RTS coding rate corresponding to the candidate beam with good beam quality is higher than the RTS coding rate corresponding to the candidate beam with poor beam quality. Since the RTS coding code rate of each RTS is different, on a relatively poor beam, a lower RTS coding code rate is used, so that the beam can transmit data using the RTS coding code rate. At this time, the network device can select the beam with the highest RTS encoding bit rate and the successful RTS/CTS handshake to transmit data.

In this embodiment of the present application, the network device transmits RTS on multiple candidate beams at one time, and adopts different RTS coding code rates, so that even if there is interference on the high-quality beam, it is possible to find a sub-optimal beam, and use the sub-optimal beam in the sub-optimal beam. The data is transmitted at a low RTS encoding bit rate to increase the system capacity.

If there is no restriction that the RTS coding rate corresponding to the candidate beam with good beam quality is higher than the RTS coding rate corresponding to the candidate beam with poor beam quality, the RTS coding rate corresponding to the candidate beam with good beam quality may be lower than the RTS coding rate corresponding to the candidate beam with poor beam quality. The RTS coding code rate corresponding to the candidate beam of the The coding rate and beam quality determine the target beam used to transmit data. That is to say, the RTS coding code rate and beam quality are comprehensively considered to determine the target beam, which can be specifically determined according to the actual situation, which will not be repeated here.

In yet another implementation manner, determining a target beam used for data transmission from at least two candidate beams according to a preset rule may include: among the at least two candidate beams, determining an undisturbed candidate beam or a CTS-received candidate beam. The candidate beam is the target beam used to transmit data. In this way, if only one candidate beam is not interfered with among the at least two candidate beams for transmitting RTS, or if CTS is received on only one candidate beam, then this one candidate beam is determined as the target beam used for data transmission.

FIG. 7 is a schematic diagram of signaling interaction of a processing method provided by another embodiment of the present application. As shown in FIG. 7, on the basis of the process shown in FIG. 2, before step S10, the processing method in this embodiment may further include the following steps:

S00. The terminal device sends a beam measurement result.

Optionally, the beam measurement result includes measurement results of multiple beams, and the beam measurement results are used to instruct the network device to determine the candidate beam used for sending the RTS. In an implementation scenario, the terminal device performs beam measurement, and reports the result of the beam measurement to the network device, so that the network device determines the connection quality of different downlink beams according to the result of the beam measurement, and determines the candidate beam used for sending RTS. .

Optionally, the result of the beam measurement includes at least one of the following: RSRP, RSRQ, SINR, and the like. These parameter values reflect the quality of the corresponding beam to a certain extent. Exemplarily, lower SINR means worse beam quality; lower RSRP means worse beam quality; lower RSRQ means worse beam quality. Conversely, higher SINR means better beam quality; higher RSRP means better beam quality; higher RSRQ means better beam quality.

For example, for the three types of RSRP, RSRQ and SINR, the result of beam measurement may include only RSRP; or, the result of beam measurement may only include RSRQ; or, the result of beam measurement may only include SINR; or, the result of beam measurement may Only include RSRP and RSRQ; or, the result of beam measurement may include only RSRP and SINR; or, the result of beam measurement may only include RSRQ and SINR; or, the result of beam measurement may include RSRP, RSRQ, and SINR at the same time.

Optionally, the network device receives the beam measurement result, and performs step S01.

S01. Determine at least two candidate beams according to the beam measurement result.

Illustratively, based on the results of the beam measurement, the network device sorts the beam qualities of the beams contained therein in a preset order from high to low or from low to high, and selects at least two beams with better beam qualities as candidate beams. .

Optionally, the result of the beam measurement is included in the measurement report. The terminal device sends a measurement report to the network device, and after receiving the measurement report, the network device parses the measurement report to obtain a beam measurement result, and executes step S01.

Still referring to FIG. 3 , the terminal device performs beam measurement, and feeds back the result of the beam measurement to the base station. Optionally, beam 2 has the best beam quality because it is a direct beam, followed by beam 1, and beam 3 is the worst. In one case, there are other wireless access points in the direction of beam 2, and there is interference. At this time, if the base station has data to transmit, the RTS is first sent on the three beams. The RTS coding rate on beam 2 is the highest, followed by beam 1, and beam 3 is the lowest. Because there is interference on beam 2, the terminal device cannot receive the RTS on beam 2 and cannot reply to the corresponding CTS; however, since there is no interference on beam 1 and beam 3 and a lower RTS coding rate is used, the terminal The device can receive the RTS on these two beams and reply to the CTS corresponding to beam 1 and beam 3. After receiving the two CTSs, the base station knows that there is interference on beam 1, so it selects the sub-optimal beam 1 to send data at the corresponding RTS coding rate. Therefore, even if there is interference in beam 2, the network device can still quickly find the beam without interference and transmit data at the correct transmission rate.

Optionally, after step S40, data transmission is performed between the terminal device and the network device.

Optionally, the terminal device sends uplink data to the network device, and/or the terminal device receives downlink data sent by the network device. When the terminal device has uplink data to transmit, it sends the uplink data to the network device; optionally, the network device receives the uplink data from the terminal device. When the network device has downlink data to transmit, the downlink data is sent to the terminal device; optionally, the terminal device receives the downlink data from the network device.

FIG. 8 is a schematic diagram of signaling interaction of a processing method provided by another embodiment of the present application. The embodiment of the present application provides a processing method, which is applied to the above-mentioned network device and terminal device. As shown in FIG. 8 , the processing method of this embodiment includes the following steps:

S10. Send RTS on at least two candidate beams to obtain corresponding CTS.

S21. In response to the RTS received on at least one candidate beam, generate or determine a CTS corresponding to the RTS according to the time difference threshold and the RTS.

It can be understood that step S21 is a further refinement of the above step S20. Compared with step S20, a time difference threshold is introduced in this step to determine the receiving time difference of the RTS received on different candidate beams. In some embodiments, the terminal device generates or determines the CTS corresponding to the RTS according to the time difference threshold and the RTS, which may include at least one of the following:

That is to say, the terminal device generates or determines the CTS corresponding to the RTS according to the time difference threshold and the RTS, which may be specifically: first, determine whether the RTS received on at least one candidate beam is the first RTS received by the terminal device, Optionally, the first RTS refers to the first RTS within a preset duration, such as one second or one millisecond or one microsecond, and so on. When the RTS received on at least one candidate beam is the first RTS, a CTS corresponding to the RTS is generated or determined. Or, when the RTS received on at least one candidate beam is not the first RTS, the time difference between the reception time of the RTS and the reception time of the first RTS is determined, and the magnitude of the time difference and the time difference threshold is determined. Optionally, if the time difference is less than or equal to the time difference threshold, the CTS corresponding to the RTS is generated or determined; or, if the time difference is greater than the time difference threshold, the CTS corresponding to the RTS is not generated or determined.

It should be added that the above-mentioned "second RTS" generally refers to the RTS that is not the first RTS, that is, the subsequently received RTS. In addition, the case where the time difference is equal to the time difference threshold can be combined with the case where the time difference is smaller than the time difference threshold as described above, to generate or determine the CTS corresponding to the RTS, that is, generate or determine the RTS when the time difference is less than or equal to the time difference threshold The corresponding CTS; or, combined with the case where the time difference is greater than the time difference threshold, so as not to generate or determine the CTS corresponding to the RTS, that is, when the time difference is greater than or equal to the time difference threshold, the CTS corresponding to the RTS is not generated or uncertain. , depending on the actual needs.

In the embodiment of the present application, when the time difference is greater than the threshold time difference, the corresponding CTS is not fed back, so as to reduce the power consumption of the terminal device, thereby prolonging the standby time of the terminal device.

Optionally, the configuration manner of the time difference threshold may include at least one of the following:

Configured through RRC signaling;

Indicated by MAC CE;

Indicated by DCI.

In an implementation scenario, the time difference threshold may be configured only through RRC signaling; or, the time difference threshold may only be indicated through MAC CE; or the time difference threshold may only be indicated through DCI; or, the time difference threshold may be configured through RRC signaling, and the MAC CE Indicate the time difference threshold; or, configure the time difference threshold through RRC signaling, and indicate the time difference threshold through DCI; or, indicate the time difference threshold through DCI, and indicate the time difference threshold through MAC CE; or, configure the time difference threshold through RRC signaling, and indicate through DCI The time difference threshold, and the time difference threshold is indicated by the MAC CE.

When configuring the time difference threshold, the present application does not limit the specific type and/or transmission time of the configuration signaling. When leaving, when the time difference threshold is configured through RRC signaling, this application does not limit the specific type and transmission time of RRC signaling. Configuration (RRC Connection Reconfiguration) signaling or RRC Connection Setup (RRC Connection Setup) signaling, etc.; or, RRC signaling involved after a terminal device establishes a connection with a network device.

After generating or determining the CTS corresponding to the RTS, the terminal device performs step S30.

S30. Send the CTS on the corresponding candidate beam.

Next, the network device executes step S40.

In this embodiment of the present application, the network device sends the RTS to the terminal device on at least two candidate beams to obtain the corresponding CTS, and based on the CTS, determines the target beam used for data transmission from the at least two candidate beams according to preset rules, The CTS is a CTS corresponding to the RTS generated or determined by the terminal device according to the time difference threshold and the RTS. Since the network device sends the RTS to the terminal device through at least two candidate beams, and determines the target beam used for data transmission from the at least two candidate beams, when one of the candidate beams has interference, other non-interfering beams can also be used. The candidate beams are used for data transmission, so the system capacity can be improved.

If there is no restriction that the RTS coding rate corresponding to the candidate beam with good beam quality is higher than the RTS coding rate corresponding to the candidate beam with poor beam quality, the RTS coding rate corresponding to the candidate beam with good beam quality may be lower than the RTS coding rate corresponding to the candidate beam with poor beam quality The RTS coding code rate corresponding to the candidate beam of the The coding rate and beam quality determine the target beam used to transmit data. That is to say, the RTS coding code rate and beam quality are comprehensively considered to determine the target beam, which can be specifically determined according to the actual situation, which will not be repeated here.
