Description

Processing method, device, system and storage medium

Technical Field

Embodiments of the present application relate to the field of communications technologies, and in particular, to a processing method, device, system, and storage medium.

Background

Based on comprehensively considering the realization of LTE (Long Term Evolution ) technology and the fair coexistence of WLAN, the 3GPP (3 rd Generation Partnership Project, third generation partnership project) introduces the LAA (Licence Assisted Access, permission auxiliary access) technology, and based on carrier aggregation or dual connection, the unlicensed carrier access is assisted by the licensed carrier to realize the supplement of the data service bearer of the long term evolution network; and, LBT (Listen Before Talk ) and other functions are introduced so that long term evolution technology and other wireless technologies can fairly coexist. Optionally, the LBT function refers to that the transmitting antenna listens to the interference sources within 360 degrees around before transmitting data, if the energy of the interference sources is greater than the threshold value, the co-channel interference is considered to exist, and then the data is not transmitted until the energy of the interference sources is less than the threshold value.

With the evolution of the 5G communication system towards high frequency, since the energy of the transmission beam is highly concentrated and the coverage area is narrow, if the communication device performs the LBT function before transmitting data, this will definitely affect the system capacity, so how to increase the system capacity is a considerable problem.

The foregoing description is provided for general background information and does not necessarily constitute prior art.

The achievement of the objects, functional features and advantages 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 way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of 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, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Firstly, explanation is made on nouns according to embodiments of the present application:

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

The RTS/CTS protocol, i.e. the request to send/grant to send protocol, is equivalent to a handshake protocol, and is mainly used to solve the problem of "Hidden Stations". "hidden site" refers to a site that cannot detect the presence of a media competitor due to too far distance. For example, the base station a transmits data to the terminal device B, and the base station C does not detect that the base station a transmits data to the terminal device B, so that the base station a and the base station C simultaneously transmit data to the terminal device B, which causes signal collision and finally results in data transmission failure. "hidden sites" are often found in large units (typically in outdoor environments), which can result in efficiency losses and require error recovery mechanisms. When large-capacity files need to be transferred, the phenomenon of hiding the site needs to be stopped. IEEE802.11 provides the following solutions: in the parameter configuration, if the RTS/CTS protocol is used, the upper limit number of bytes to be transmitted is set at the same time, and once the data to be transmitted is greater than the upper limit value, the RTS/CTS protocol is started:

Firstly, a base station A sends RTS to a terminal device B through a beam, the base station A indicates that the base station A needs to send data to the terminal device B, after the terminal device B receives the RTS, the base station A sends CTS to all the base stations, the base station A indicates that the base station A is ready to send data to the terminal device B, and other base stations temporarily do not send data to the terminal device B, namely the other base stations keep silent for a period of time; then, the base station A transmits data to the terminal equipment B; after the terminal device B receives the data, it broadcasts an ACK (Acknowledge character, acknowledgement character) acknowledgement frame to all base stations, so that all base stations can again listen to and contend with the channel equally.

With respect to the present, continuous evolution to high frequency is an important means for 5G (5 th Generation mobile networks or 5th Generation wireless systems, 5th-Generation, fifth Generation mobile communication technology) systems to continue to increase system capacity. In the latest R17 standard making process, the expansion of the existing 5G system to 52 GHz-71 GHz is an important subject. Because a part of sub-frequency bands belong to unlicensed frequency bands according to different countries and regions in the frequency band of 52 GHz-71 GHz, the problem to be solved first is the coexistence problem of a 5G system and other wireless access networks (such as WIFI). In order to solve the coexistence problem, in the existing LTE system, an LBT function using LAA is already available.

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

Based on the above-mentioned problems, the present application provides a processing method, apparatus, system and storage medium for improving system capacity, in which, in the case that the current beam has interference, data transmission is performed by using other non-interference beams, without waiting for the end of interference on the current beam to retransmit data, so as to improve system capacity. Optionally, the RTS is transmitted over at least two beams when the network device and the terminal device handshake based on the RTS/CTS protocol.

The processing method provided by the embodiment of the application can be applied to the communication system architecture schematic diagram shown in fig. 1. As shown in fig. 1, the communication system includes: AMF/UPF, access network equipment and terminal equipment. Optionally, the access network device includes: a first base station and a second base station. Illustratively, the first base station and the second base station are both base stations of the new air interface system. In the scenario shown in fig. 1, the first base station and the second base station share one AMF/UPF, optionally, the first base station and the AMF (Access and Mobile Management Function, access and mobility management function)/UPF (User Plane Function ) are connected through an interface NG-C, the first base station and the second base station are connected through an interface X2-C, and the terminal device accesses the first base station and the second base station simultaneously. Of course, in other scenarios, the first base station and the second base station may also have separate AMFs/UPFs, which are not limited in this embodiment of the present application.

Alternatively, the communication system may be a system in a scenario of high reliability and low latency communication in a 5G communication system.

In a specific implementation, the following embodiments of the present application may be applied, for example, to the following scenarios:

when a user browses videos by using the terminal equipment, application software related to the videos in the terminal equipment can firstly download a certain amount of data to be cached in the terminal equipment, so that user experience is smoother. And stopping downloading the data after the cached data quantity reaches the preset upper threshold, and continuing to download until the cached data quantity reaches the preset upper threshold after the cached data quantity is smaller than the preset lower threshold, so that the operation is repeated. Before transmitting data, the base station needs to determine the beam used for transmitting the data, optionally, the base station sends RTS to the terminal device on at least two candidate beams to obtain corresponding CTS, determines the target beam used for transmitting the data from the at least two candidate beams based on the CTS, and completes downloading.

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

Fig. 2 is a signaling interaction schematic diagram of a processing method according to an embodiment of the present application. The embodiment of the application provides a processing method which is applied to network equipment and terminal equipment. As shown in fig. 2, the processing method of the present embodiment includes the following steps:

s10, RTS is sent on at least two candidate beams to obtain corresponding CTS.

To increase system capacity, embodiments of the present application use at least two candidate beams in handshaking based on the RTS/CTS protocol. Thus, even if some of the at least two candidate beams have interference on them, other candidate beams without interference can be determined as target beams.

In an implementation scenario, when the network device has data to be transmitted to the terminal device, the network device performs step S10. Alternatively, the determination of candidate beams may refer to the subsequent embodiments. Illustratively, referring to fig. 3, based on 3 candidate beams, the network device sends RTS to the terminal device, one RTS per candidate beam.

Alternatively, the RTS corresponding to different candidate beams may be the same, i.e., the same RTS is sent on candidate beam 1 and candidate beam 2; alternatively, RTS corresponding to different candidate beams may also be different, as illustrated in fig. 4, where RTS transmitted through N candidate beams are respectively: RTS (RTS) ₀ 、RTS ₁ 、RTS ₂ 、RTS ₃ 、……、RTS _N-1 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 RTS, e.g., the network device sends RTS to the terminal device on 5 candidate beams, and the terminal device receives RTS on only 4 or fewer of the candidate beams.

S20, generating or determining a CTS corresponding to the RTS in response to the RTS received on the at least one candidate beam.

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. For the specific manner in which the terminal device generates or determines the CTS, reference may be made to the related art, and will not be described herein. After that, the terminal device performs S30.

S30, sending CTS on the corresponding candidate wave beams.

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

Illustratively, referring to fig. 5, based on 3 candidate beams, the terminal device sends CTS to the network device, one CTS per candidate beam.

Alternatively, CTS corresponding to different candidate beams may be the same, i.e., the same CTS is transmitted on candidate beam 1 and candidate beam 2; alternatively, CTS corresponding to different candidate beams may also be different, as illustrated in fig. 6, corresponding to fig. 4. The CTS sent by the terminal device through the N-2 candidate beams are respectively: CTS (clear to send) ₀ 、CTS ₂ 、CTS ₃ 、……、CTS _N-1 . In the example shown in fig. 6, the terminal device does not receive the RTS sent by the network device ₁ Other RTS are considered to be receiving normally.

Optionally, the network device receives the CTS. Similarly, considering that there may be interference on the beam, the number of CTS received by the network device may be less than the number of CTS transmitted by the terminal device, as shown in fig. 6, where the network device does not receive CTS transmitted by the terminal device ₀ Other CTS's are considered to be normally received.

Next, the network device performs 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 among the candidate beams for transmitting CTS according to a preset rule. Optionally, the candidate beam for transmitting CTS is a beam of at least two candidate beams as previously described.

In one implementation, the network device determines, according to a preset rule, a target beam used for transmitting data from at least two candidate beams, and may include: among candidate beams that receive CTS, the candidate beam with the best beam quality is determined as the target beam used for transmitting data. Alternatively, it may be stated from a plurality of angles that the beam quality is good, e.g. the value of the measured parameter is high. Alternatively, 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 probability of success of determining the target beam used for transmitting data in at least two candidate beams is significantly higher than the probability of success of determining one beam as the target beam used for transmitting data, so that the embodiment of the present application can improve the system capacity.

Alternatively, the CTS is directional, corresponding to the RTS. That is, the network device that does not transmit the corresponding RTS does not transmit data to the terminal device for a while even if it receives the CTS, i.e., the rest of the network devices remain silent for a period of time.

In the embodiment of the application, the network equipment sends RTS to the terminal equipment on at least two candidate beams to obtain corresponding CTS, and determines the target beam used for transmitting data from the at least two candidate beams according to the preset rule based on the CTS. Because the network device sends RTS to the terminal device through at least two candidate beams, and determines the target beam used for transmitting data from at least two candidate beams, when one candidate beam has interference, other non-interference candidate beams can be used for data transmission, and therefore the system capacity can be improved.

Optionally, aIf the RTS is encoded with a fixed RTS code BR (Bit Rate) and then transmitted, this design can only indicate whether the current beam connection is interfered with at the fixed RTS code Rate, and there may be other beams without interference that can use a higher RTS code Rate for communication. Thus, different candidate beams may use different RTS coding rates, considering that the beam quality of the different candidate beams may be different. That is, among the at least two candidate beams, RTS encoding rates corresponding to different candidate beams are different. Illustratively, still referring to FIG. 4, RTS ₀ The corresponding RTS coding code rate is BR ₀ ，RTS ₁ The corresponding RTS coding code rate is BR ₁ And so on.

Optionally, the RTS carries information indicating an RTS coding rate, for example, the RTS carries a specific RTS coding rate; alternatively, the RTS carries information implicitly indicating the RTS coding rate, for example, the RTS carries a unique identifier, which is used to indicate the RTS coding rate, and the like, so as to inform the terminal device. Optionally, the CTS employs the same RTS coding rate as the corresponding RTS.

In another implementation manner, determining, from at least two candidate beams, a target beam used for transmitting data according to a preset rule may include: among the candidate beams that receive the CTS, the candidate beam that has the highest corresponding RTS code rate is determined as the target beam used for transmitting data.

Alternatively, the higher the RTS coding rate, the lower the tolerance of RTS to interference, so 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 code rate of each RTS is different, the lower RTS code rate is used on the relatively worse beam, so that the beam can transmit data using the RTS code rate. The network device may then select the beam with the highest RTS coding rate and the RTS/CTS handshake successful to transmit data.

In the embodiment of the application, the network equipment sends RTS on a plurality of candidate beams once and adopts different RTS coding rates, so that even if interference exists on a high-quality beam, a suboptimal beam can be found, and data is transmitted on the suboptimal beam with a low RTS coding rate, so that the system capacity is improved.

If there is no limitation that the RTS code rate corresponding to the candidate beam with good beam quality is higher than the RTS code rate corresponding to the candidate beam with poor beam quality, the RTS code rate corresponding to the candidate beam with good beam quality may be lower than the RTS code rate corresponding to the candidate beam with poor beam quality, where in this case, the determining, according to a preset rule, the target beam used for transmitting data from at least two candidate beams may include: among the candidate beams that receive CTS, the target beam used for transmitting data is determined according to the corresponding RTS coding rate and beam quality. That is, the RTS coding rate and the beam quality are considered comprehensively to determine the target beam, which can be determined according to the actual situation, and will not be described herein.

In yet another implementation, determining, from at least two candidate beams, a target beam used for transmitting data according to a preset rule may include: among the at least two candidate beams, a candidate beam that is not interfered or a candidate beam that receives CTS is determined as a target beam used for transmitting data. Thus, if only one candidate beam is not interfered, or a CTS is received on only one candidate beam, of at least two candidate beams for transmitting RTS, the one candidate beam is determined to be the target beam used for transmitting data.

Fig. 7 is a signaling interaction schematic diagram of a processing method according to another embodiment of the present application. As shown in fig. 7, the processing method in this embodiment may further include the following steps, before step S10, on the basis of the flow shown in fig. 2:

s00, the terminal equipment transmits the beam measurement result.

Optionally, the results of the beam measurement comprise measurement results of a plurality of beams, the results of the beam measurement being used to instruct the network device to determine candidate beams to use 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 connection quality of different downlink beams according to the result of the beam measurement, and determines candidate beams used for sending the RTS from the connection quality.

Optionally, the result of the beam measurement comprises at least one of: RSRP, RSRQ, SINR, etc. These parameter values reflect to some extent the quality of the corresponding beam. Illustratively, a lower SINR indicates a worse beam quality; lower RSRP means poorer beam quality; lower RSRQ indicates poorer beam quality. Conversely, a higher SINR indicates a better beam quality; higher RSRP means better beam quality; higher RSRQ indicates better beam quality.

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

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

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

Illustratively, based on the result of the beam measurement, the network device orders the beam quality 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 quality as candidate beams.

Optionally, the result of the beam measurement is included in the measurement report. The terminal device sends the 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. Alternatively, beam 2 is the direct path, beam quality is the best, beam 1 times, and beam 3 is the worst. In one case, there are other wireless access points in the beam 2 direction, and interference is present. At this time, if the base station has data to transmit, RTS is transmitted on three beams first, the RTS code rate is highest on beam 2, beam 1 times, and beam 3 is lowest. Because of the interference on the beam 2, the terminal equipment cannot receive the RTS on the beam 2 and cannot reply to the corresponding CTS; and the beams 1 and 3 have no interference, and a lower RTS coding rate is adopted, so that the terminal equipment can receive RTS on the two beams and reply CTS corresponding to the beams 1 and 3. The base station knows that there is interference on beam 1 after receiving these two CTS, and therefore selects sub-optimal beam 1 to transmit data at the corresponding RTS coding rate. Thus, even if beam 2 has interference, the network device can quickly find a 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 equipment has uplink data to be transmitted, the uplink data is sent to the network equipment; optionally, the network device receives uplink data from the terminal device. When the network equipment has downlink data to be transmitted, the downlink data is sent to the terminal equipment; optionally, the terminal device receives downlink data from the network device.

Fig. 8 is a signaling interaction schematic diagram of a processing method according to another embodiment of the present application. The embodiment of the application provides a processing method which is applied to network equipment and terminal equipment. As shown in fig. 8, the processing method of the present embodiment includes the steps of:

s10, RTS is sent on at least two candidate beams to obtain corresponding CTS.

S21, responding to RTS received on at least one candidate beam, and generating or determining CTS corresponding to the RTS according to the time difference threshold and the RTS.

It will be appreciated that step S21 is a further refinement of step S20 described above. Compared with the step S20, a time difference threshold is introduced in the step to judge the receiving time difference of 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, and may include at least one of the following:

when the time difference between the second RTS received on the at least one candidate beam and the first RTS received is greater than a time difference threshold, not generating or determining a corresponding CTS;

That is, the terminal device generates or determines the CTS corresponding to the RTS according to the time difference threshold and the RTS, which may specifically be: first, it is determined whether an RTS received on at least one candidate beam is the first RTS received by the terminal device, optionally the first RTS is the first RTS within a preset duration, for example one second or one millisecond or one microsecond, etc. When the RTS received on the 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, determining a time difference between the time of reception of the RTS and the time of reception of the first RTS, and determining the magnitude of the time difference and the time difference threshold. Optionally, if the time difference is less than or equal to a time difference threshold, generating or determining a CTS corresponding to the RTS; alternatively, if the time difference is greater than the time difference threshold, the CTS corresponding to the RTS is not generated or not determined.

It is added that the "second RTS" described above generally refers to an RTS that is not the first RTS, i.e., a subsequently received RTS. In addition, the case where the time difference is equal to the time difference threshold may be combined with the case where the time difference is less than the time difference threshold as described above, for generating or determining the CTS corresponding to the RTS, that is, generating or determining the CTS corresponding to the RTS when the time difference is less than or equal to the time difference threshold; or the RTS is combined with the situation that the time difference is larger than the time difference threshold value, so that the CTS corresponding to the RTS is not generated or not determined, namely, when the time difference is larger than or equal to the time difference threshold value, the CTS corresponding to the RTS is not generated or not determined, and the CTS is not generated or is not determined, and the CTS is not generated or is not determined, and the CTS is not determined.

According to the embodiment of the application, the corresponding CTS is not fed back when the time difference is larger than the threshold time difference, so that the power consumption of the terminal equipment is reduced, and the standby time of the terminal equipment is further prolonged.

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

configuration by RRC signaling;

indicated by MAC CE;

indicated by DCI.

In one implementation scenario, the time difference threshold may be configured solely by RRC signaling; alternatively, the time difference threshold is indicated only by the MAC CE; alternatively, the time difference threshold is indicated only by DCI; or, configuring a time difference threshold through RRC signaling, and indicating the time difference threshold through MAC CE; or, configuring a time difference threshold through RRC signaling, and indicating the time difference threshold through DCI; alternatively, the time difference threshold is indicated by DCI and the time difference threshold is indicated by MAC CE; alternatively, the time difference threshold is configured by RRC signaling, indicated by DCI, and indicated by MAC CE.

The application is not limited to a particular type and/or transmission time of configuration signaling when configuring the time difference threshold. Leaving, when the time difference threshold is configured through RRC signaling, the present application does not limit specific types and transmission time of RRC signaling, for example, RRC signaling involved in a connection establishment process between the terminal device and the network device, such as RRC connection reconfiguration (RRC Connection Reconfiguration) signaling or RRC connection establishment (RRC Connection Setup) signaling; or RRC signaling involved after the terminal device establishes a connection with the network device.

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

S30, sending CTS on the corresponding candidate wave beams.

Next, the network device performs S40.

According to the embodiment of the application, network equipment sends RTS to terminal equipment on at least two candidate beams so as to obtain corresponding CTS, and determines a target beam used for transmitting data from the at least two candidate beams according to a preset rule based on the CTS, wherein the CTS is CTS which is generated or determined by the terminal equipment according to a time difference threshold and corresponds to the RTS. Because the network device sends RTS to the terminal device through at least two candidate beams, and determines the target beam used for transmitting data from at least two candidate beams, when one candidate beam has interference, other non-interference candidate beams can be used for data transmission, and therefore the system capacity can be improved.

Alternatively, if the RTS is encoded with a fixed RTS code BR (Bit Rate) and then transmitted, this design can only account for whether the current beam connection is interfered with at the fixed RTS code Rate, and there may be a possibility that other beams without interference can communicate using a higher RTS code Rate. Thus, different candidate beams may use different RTS coding rates, considering that the beam quality of the different candidate beams may be different. That is, among the at least two candidate beams, RTS encoding rates corresponding to different candidate beams are different. Illustratively, still referring to FIG. 4, RTS ₀ The corresponding RTS coding code rate is BR ₀ ，RTS ₁ The corresponding RTS coding code rate is BR ₁ And so on.
