Detailed Description

For ease of understanding, first, the concepts related to the present application will be explained.

The terminal equipment: the terminal equipment can be deployed on land, including indoors or outdoors, is handheld, worn or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet personal computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a vehicle-mounted terminal device, a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a wearable terminal device, and the like. The terminal device according to the embodiments of the present application may also be referred to as a terminal, a User Equipment (UE), an access terminal device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent, or a UE apparatus. The terminal equipment may also be fixed or mobile.

A network device: generally having wireless transceiving capability, the network device may have mobile features, for example, the network device may be a mobile device. Alternatively, the network device may be a communications satellite, balloon station. For example, communication satellites may be classified into Low Earth Orbit (LEO) satellites, Medium Earth Orbit (MEO) satellites, Geosynchronous Earth Orbit (GEO) satellites, High Elliptic Orbit (HEO) satellites, and the like according to the difference in orbital altitude. For example, LEO satellites typically have orbital altitudes ranging from 500km to 1500km, and orbital periods (periods of rotation around the earth) of about 1.5 hours to 2 hours. The signal propagation delay of inter-user single-hop communication is about 20ms, and the inter-user single-hop communication delay refers to the transmission delay from a terminal device to a network device or the delay from the network device to the transmission device. The maximum satellite visibility time is about 20 minutes, which is the longest time that the beam of the satellite covers a certain area of the ground, and the LEO satellite moves relative to the ground, and the ground area covered by the LEO satellite changes as the satellite moves. The LEO satellite has short signal propagation distance, less link loss and low requirement on the transmitting power of terminal equipment. The orbit altitude of GEO satellites is typically 35786km with an orbit period of 24 hours. The signal propagation delay for inter-user single-hop communications is approximately 250 ms. To ensure coverage of the satellite and to increase system capacity of the communication network, the satellite may cover the ground with multiple beams, for example, a satellite may form tens or hundreds of beams to cover the ground, and a beam may cover a ground area having a diameter of tens to hundreds of kilometers. Of course, the network device may also be a base station disposed on land, water, or other locations, for example, the network device may be a next generation base station (gNB) or a next generation evolved node b (ng-eNB). The gNB provides a user plane function and a control plane function of a new radio interface (NR) for the UE, and the ng-eNB provides a user plane function and a control plane function of an evolved universal terrestrial radio access (E-UTRA) for the UE, where it should be noted that the gNB and the ng-eNB are only names used for representing a base station supporting a 5G network system and do not have a limiting meaning. The network device may also be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a base station (NB) in a WCDMA system, or an evolved node B (eNB or eNodeB) in an LTE system. Alternatively, the network device may also be a relay station, an access point, an in-vehicle device, a wearable device, and a network-side device in a network after 5G or a network device in a PLMN network for future evolution, a Road Side Unit (RSU), and the like.

Non-terrestrial communication to the network: the non-terrestrial communication network NTN technology generally provides communication services to terminal devices on the ground by means of satellite communication. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communication is not limited by regions, for example, general terrestrial communication cannot cover regions where communication equipment cannot be set up, such as oceans, mountains, deserts, and the like, or communication coverage is not performed due to sparse population, and for satellite communication, since one satellite can cover a large ground and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communication. Second, satellite communication has great social value. Satellite communication can cover in remote mountain areas, poor and laggard countries or areas with low cost, so that users in the areas can enjoy advanced voice communication and mobile internet technology, the digital gap of developed areas is favorably reduced, and the development of the areas is promoted. Thirdly, the satellite communication distance is long, and the communication cost is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form dozens of or even hundreds of beams to cover the ground; a satellite beam may cover a terrestrial region several tens to hundreds of kilometers in diameter.

Automatic retransmission request: an automatic repeat request (ARQ) is an error correction protocol, after a receiving side receives data from a sending side, whether the received data is damaged is judged according to a forward error correction technique, if the received data is not damaged, an Acknowledgement (ACK) is fed back to the sending side, wherein the ACK is used for informing the sending side that the data is correctly received, and the sending side can continue to send new data after receiving the ACK; if the data is corrupted, the receiving side discards the corrupted data and feeds back non-acknowledgement (NACK) information to the transmitting side, and the transmitting side may retransmit the original data to the receiving side after receiving the NACK.

Hybrid automatic repeat request: hybrid automatic repeat request (HARQ) is a technology formed by combining forward error correction coding (FEC) and ARQ, on the basis of the above-described ARQ, data with errors in previous transmission is buffered, and is diversity-combined with existing damaged data, so as to improve the probability of correct information decoding, and the technology combining diversity combining and ARQ is called HARQ, and the difference between HARQ and ARQ is that: 1) in the HARQ, the damaged data can be buffered, and in the ARQ, the damaged data can be directly discarded; 2) in the HARQ, the buffered data and the current data are soft-combined and decoded to improve the correct detection rate.

A transmission block: data sent from a Medium Access Control (MAC) layer to a physical layer is organized in the form of Transport Blocks (TBs), wherein one TB corresponds to a data block including one MAC Protocol Data Unit (PDU), and the data block is sent in one Transmission Time Interval (TTI) and is also a unit of HARQ retransmission.

After explaining the related concepts related to the present application, the architecture of the communication system in the present application is explained below with reference to fig. 1 to 2.

Fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the present application. Referring to fig. 1, a terminal device 101 and a satellite 102 are included, and wireless communication is enabled between the terminal device 101 and the satellite 102. The network formed between the terminal equipment 101 and the satellite 102 may also be referred to as an NTN. In the architecture of the communication system shown in fig. 1, the satellite 102 has the function of a base station, and direct communication is possible between the terminal apparatus 101 and the satellite 102. Under the system architecture, the satellites 102 may be referred to as network devices.

Fig. 2 is a schematic architecture diagram of another communication system according to an embodiment of the present application. Referring to fig. 2, the terminal device 201, the satellite 202 and the base station 203 are included, wireless communication can be performed between the terminal device 201 and the satellite 202, and communication can be performed between the satellite 202 and the base station 203. The network formed between the terminal equipment 201, the satellite 202 and the base station 203 may also be referred to as NTN. In the architecture of the communication system shown in fig. 2, the satellite 202 does not have the function of a base station, and communication between the terminal apparatus 201 and the base station 203 requires relay through the satellite 202. Under this system architecture, the base station 203 may be referred to as a network device.

On the basis of the above-mentioned embodiments, the following further details are provided for the background art related to the present application:

first, a downlink HARQ mechanism in NR is explained:

in NR, there are two retransmission mechanisms, which are respectively a Medium Access Control (MAC) layer HARQ mechanism and a Radio Link Control (RLC) layer ARQ mechanism, where the MAC layer HARQ mechanism can provide fast retransmission, the RLC layer ARQ mechanism can provide reliable data transmission, and in the data transmission process, retransmission of lost or erroneous data is mainly handled by the MAC layer HARQ mechanism and is supplemented by the RLC layer retransmission function.

HARQ uses a Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-and-wait protocol, after a sender sends a TB, the sender stops waiting for an Acknowledgement (ACK), so that the sender stops waiting for an ACK after each transmission, which results in low user throughput.

Therefore, a plurality of parallel HARQ processes can be used in NR, and when one HARQ process is waiting for ACK, the sender can continue to send data by using another HARQ process, and the HARQ processes jointly form a HARQ entity which combines with a stop-and-wait protocol and allows continuous data transmission.

The HARQ includes a difference between an uplink HARQ and a downlink HARQ, where the uplink HARQ is for uplink data transmission and the downlink HARQ is for downlink data transmission. The two are independent of each other.

Based on the specification of the current NR protocol, the terminal device has its own HARQ entity corresponding to each serving cell, each HARQ entity maintains a group of parallel downlink HARQ processes, and each downlink carrier currently supports 16 HARQ processes at most.

In a possible implementation manner, the network device may indicate the maximum downlink HARQ process number to the terminal device through Radio Resource Control (RRC) signaling according to a network deployment condition; in another possible implementation manner, if the network device does not provide corresponding configuration parameters, the default number of downlink HARQ processes may be 8.

Wherein, each downlink HARQ process corresponds to an HARQ process Identity (ID), and a Broadcast Control Channel (BCCH) uses a dedicated broadcast HARQ process.

For terminal equipment which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB simultaneously; for a terminal device supporting downlink spatial multiplexing, each downlink HARQ process may process 1 or 2 TBs at the same time.

HARQ is divided into synchronous and asynchronous types in time domain, and non-adaptive and adaptive types in frequency domain, where the downlink in NR uses an asynchronous adaptive HARQ mechanism, where asynchronous HARQ, i.e. retransmission, may occur at any time, the time interval between retransmission of the same TB and the last transmission is not fixed, and adaptive HARQ may change the frequency domain resource and Modulation and Coding Scheme (MCS) used for retransmission.

Next, introduction is made to downlink data transmission in NR:

before the network device transmits downlink data to the terminal device, the network device needs to allocate a suitable time-frequency domain resource for downlink transmission to the terminal device, and notify the allocated time-frequency domain resource to the terminal device through a Physical Downlink Control Channel (PDCCH) carrying a scheduling signaling, where the PDCCH may include: the allocated time-frequency domain resource position, MCS, the used downlink HARQ process ID, the initial retransmission indication and other information.

The terminal device may receive downlink data on a corresponding resource using an indicated HARQ process according to the received PDCCH, which is described below with reference to fig. 3 to 5, where fig. 3 is a schematic diagram of a data block transmission provided in the embodiment of the present application, fig. 4 is a schematic diagram of a data block transmission provided in the embodiment of the present application, and fig. 5 is a schematic diagram of a data block transmission provided in the embodiment of the present application.

In a possible implementation manner, the process of receiving downlink data by the terminal device may include the following manners, for example:

a) if the data received by the terminal equipment is the initial transmission data and no other data currently exists in the cache of the HARQ process corresponding to the initial transmission data, the terminal equipment stores the received downlink data into the cache of the corresponding HARQ process and decodes the data.

Referring to fig. 3, the network device may be, for example, a sender, the terminal device may be a receiver, and the received data 1 is received for the first time, that is, the initial transmission data described above, and then the terminal device stores the data 1 in the buffer of the corresponding HARQ process.

b) If the data received by the terminal equipment is the initial transmission data and other data exist in the cache of the HARQ process corresponding to the initial transmission data, the terminal equipment replaces the existing data in the cache of the HARQ process with the downlink data received this time, so that the downlink data received this time is stored in the cache of the HARQ process, and the data is decoded.

Referring to fig. 4, for example, the network device may be a sender, the terminal device may be a receiver, and the received data 1 is received for the first time, that is, the initial transmission data described above and the existing data 1 in the buffer of the current HARQ process, the terminal device may replace the existing data 1 in the buffer of the HARQ process with the currently received data 2, so as to store the currently received data 2 in the buffer of the HARQ process.

c) If the terminal equipment receives the retransmission data, the terminal equipment performs soft combination on the downlink data received this time and the existing data in the cache corresponding to the HARQ process, and decodes the combined data.

Referring to fig. 5, a network device may be, for example, a sender, a terminal device serves as a receiver, and it is assumed that data 3 received by the terminal device for the second time is retransmission data, that is, the current data 3 is not transmitted for the first time but is repeatedly transmitted, as can be seen from fig. 3, data 3 received twice is incomplete, the terminal device may perform soft combining on the incomplete data 3 received this time and existing incomplete data 3 in a buffer corresponding to an HARQ process, and assuming that complete data 3 can be obtained right, the terminal device decodes the combined data at this time, and can obtain an ACK decoding result.

In a possible implementation manner, if the terminal device succeeds in decoding, the terminal device sends an ACK feedback to the network device, and after receiving the ACK, the network device may continue to schedule the newly transmitted data by using the HARQ process, for example, referring to fig. 4, and when receiving the ACK for data 1, the network device may continue to schedule the newly transmitted data 2 by using the HARQ process.

In another possible implementation, if the terminal device fails to decode, it sends NACK feedback to the network device, and after receiving NACK, the network device decides whether to continue scheduling retransmission of the data block using the HARQ or abandon scheduling of new transmission data for the data block by using the HARQ, for example, referring to fig. 5, and if the network device receives NACK for data 3, the HARQ process may be used to continue scheduling retransmission of the data block 3.

Before the network equipment receives ACK/NACK feedback from the terminal equipment for a certain HARQ process, the HARQ process cannot be used for data transmission.

In order to enhance coverage, NR further supports downlink bundling (bundling) transmission, that is, for the same downlink TB, the network device continuously and repeatedly transmits on the same frequency domain resource for multiple times, and the terminal device decodes the received data after completing reception of one bundling, where the number of times of retransmission included in the downlink bundling may be configured by the network RRC.

It should be noted that the downlink HARQ mechanism and downlink data transmission in NR described above may be well applicable to a conventional terrestrial NR system, however, compared to a cellular network adopted by the conventional terrestrial NR system, the signal propagation delay between a terminal device and a satellite in NTN is greatly increased, and if the downlink HARQ mechanism of the current terrestrial NR system is directly adopted in the NTN system, the maximum number of HARQ processes supported by the current NR protocol is 16, which is not enough to support continuous transmission of downlink data in NTN. On the other hand, if the number of downlink HARQ processes is increased, the processing complexity of the terminal device will be increased.

Based on this, in order to ensure data transmission continuity without increasing the number of HARQ processes, the introduction of a scheme for turning on/off HARQ is agreed in the NTN standardization process, and the following explicit conclusions are formed:

1. the network device may configure whether to turn on the HARQ function.

2. If the HARQ function is turned off, the terminal device does not need to send HARQ feedback for a Physical Downlink Shared Channel (PDSCH) to the network device.

3. In case of turning off HARQ feedback, HARQ retransmission is still supported in order to guarantee data transmission reliability.

4. The configuration of the HARQ function on or off may be performed on a terminal device basis, or on a HARQ process basis, or on a PDCCH basis.

The method for configuring the terminal equipment comprises the steps of configuring the terminal equipment, namely configuring HARQ functions of all HARQ processes of the terminal equipment to be in an on or off state at the same time;

for the configuration mode based on the HARQ process, that is, for multiple HARQ processes of one terminal device, the HARQ functions of a part of HARQ processes may be configured to be in an on state, and the HARQ functions of another part of HARQ processes may be configured to be in an off state.

For the configuration mode based on the PDCCH, that is, the PDCCH indicates that the HARQ feedback function of the HARQ process used in the transmission is in an on state or an off state.

Based on the above conclusion, for downlink transmission with HARQ feedback function turned off, the network device may configure repeat (retransmission) transmission or blind scheduling retransmission, and improve data transmission reliability by increasing the number of retransmissions.

However, since the network device cannot obtain ACK/NACK feedback of the terminal device, the network device does not know the actual downlink reception condition of the terminal device, and if the MCS selected by the network device is too high or the number of retransmissions is too small, downlink reception failure of the terminal device may be caused; if the MCS selected by the network device is too low or the number of retransmissions is too many, the data transmission efficiency will be affected.

Based on the above description, it can be determined that, in the current scheme in the prior art, due to the closing of the HARQ feedback function, the scheduling policy of the network device may not match the real channel environment of the terminal device, thereby affecting the communication quality.

Aiming at the problems in the prior art, the application provides the following technical conception: the terminal equipment counts the decoding result of the downlink transmission for closing the HARQ feedback, and reports the statistical result to the network equipment, so that the network equipment can be assisted to adjust scheduling parameters, such as MCS (modulation and coding scheme) level, retransmission times and the like, so that a scheduling strategy of the network equipment can be better matched with the real channel environment of the terminal equipment, and the scheduling performance and the communication quality are improved.

The communication method provided by the present application is described in detail below with reference to specific embodiments, and first described with reference to fig. 6, where fig. 6 is a flowchart of the communication method provided by an embodiment of the present application.

As shown in fig. 6, the method includes:

s601, the terminal device obtains configuration information of the network device.

In this embodiment, the configuration information may be used to determine statistical information, or the configuration information may also be used to send the statistical information to the network device, where an implementation manner of the terminal device acquiring the configuration information may be, for example: the terminal equipment is used as a receiving party to acquire and receive the configuration information from the network equipment; alternatively, the terminal device may also store the configuration information of the network device in advance, so as to obtain the configuration information of the network device from the local.

In one possible implementation, the configuration information may include a condition for sending the statistical information to the network device, for example, a time threshold may be set for certain values, and when the values satisfy the time threshold, the statistical information may be sent to the network device; or, the configuration information may include a period of sending the statistical information to the network device, or the configuration information may further include a time domain resource, a frequency domain resource, and the like of sending the statistical information to the network device.

In another possible implementation manner, the configuration information may further include at least one counter, for example, where each counter is used to implement the determination of the statistical information.

Or, in a possible implementation manner, the configuration information may further include additional indication information, for example, the configuration information may include the number of times of sending the statistical information, and the like, which is not limited in this embodiment.

S602, the terminal device determines statistical information according to the configuration information, wherein the statistical information is used for counting decoding results aiming at downlink transmission.

In this embodiment, the statistical information is used to count the decoding result for the downlink transmission, and in combination with the above description, a person skilled in the art may determine that, when the decoding is successful, the terminal device decodes for the downlink transmission, and updates the number of times of the decoding result ACK, and when the decoding is failed, updates the number of times of the decoding result NACK.

In one possible implementation, the statistical information includes at least one of the following: the number of times that the initial transmission decoding corresponds to the HARQ result is ACK, the number of times that the initial transmission decoding corresponds to the HARQ result is NACK, the number of times that the last transmission decoding corresponds to the HARQ result is NACK, and the number of times of the initial transmission decoding.

The last transmission refers to that the rest of the second data blocks are transmitted after the transmission is finished, and the first data block transmitted at the time is not transmitted.

Specifically, if a certain data is repeatedly transmitted for multiple times, the HARQ result corresponding to the decoding of the last transmission is NACK, that is, the HARQ result corresponding to the decoding of the last retransmission is NACK; if a certain data is transmitted only once, the HARQ result corresponding to the decoding transmitted last time is NACK, that is, the HARQ result corresponding to the decoding transmitted first time is NACK.

It can be understood that the sum of the number of times that the initial transmission decoding result is ACK and the number of times that the initial transmission decoding result is NACK is the number of times of initial transmission decoding.

In this embodiment, one possible implementation manner of determining the statistical information may be that the terminal device receives at least one PDSCH, where an HARQ process corresponding to each PDSCH closes an HARQ feedback function, and at this time, the terminal device does not send HARQ feedback to the network device after receiving data.

The terminal device may decode the at least one PDSCH to obtain a decoding result, where the decoding result may be ACK or NACK, and then the terminal device updates the configuration information according to the decoding result, thereby determining the statistical information.

The configuration information may include, for example, a first counter (initial _ ACK _ count), a second counter (initial _ NACK _ count), and a third counter (residual _ NACK _ count), where the first counter is used to indicate the number of times that the initial decoding result is ACK, the second counter is used to indicate the number of times that the initial decoding result is NACK, and the third counter is used to indicate the number of times that the last decoding result is NACK.

One possible implementation manner for updating the configuration information according to the decoding result may be: the counter is updated according to the decoding result, thereby determining the statistical information.

For example, if each PDSCH described above is initially transmitted, if the PDSCH decoding is successful for any PDSCH, the first counter is incremented by 1;

for any PDSCH, if the PDSCH fails to decode, adding 1 to the second counter;

for any PDSCH, if the decoding of the previous PDSCH identical to the HARQ process of the PDSCH fails, the third counter is incremented by 1.

If the PDSCH is initially transmitted and the decoding of the previous PDSCH that is the same as the HARQ process of the PDSCH fails, and whether the previous PDSCH is retransmitted or initially transmitted, it indicates that the previous PDSCH decoding fails, that is, the terminal device fails to decode the last TB of the HARQ process, then 1 is added to the third counter indicating the number of times that the decoding result of the last transmission is NACK.

The counting of the decoding results is realized by adopting the counter, the counting of the decoding results can be realized orderly and efficiently, and the processing efficiency of the counting results is improved.

Alternatively, in another possible implementation manner, the counter is not used, but the decoding result is directly counted, so as to obtain the statistical information,

in this embodiment, after the terminal device sends the statistical information, the first counter, the second counter, and the third counter may be initialized, where the initialization may set the counter to 0 or set the counter to the rest of initialization values, which is not limited in this embodiment, so as to prepare for the next statistical information and ensure the correctness of the statistical information.

S603, the terminal equipment sends the statistical information.

In a possible implementation manner, the terminal device may send, for example, the statistical information to the network device through the resource in the uplink according to the configuration information, where the configuration information may be, for example, a number threshold, and then the statistical information may be sent through a PUCCH when the number reaches the corresponding number threshold, or may also be sent through a PUSCH.

Or, for example, the terminal device may also send the statistical information to the remaining terminal devices through the resource in the secondary link according to the configuration information, and this embodiment does not limit an implementation manner of sending the statistical information by the terminal device.

The communication method provided by the embodiment of the application comprises the following steps: the terminal equipment acquires the configuration information of the network equipment. And the terminal equipment determines statistical information according to the configuration information, wherein the statistical information is used for counting the decoding result aiming at the downlink transmission.

Taking the first time threshold and the second time threshold as an example, the terminal device may send the statistical information according to the first time threshold and the second time threshold, for example, when the first counter is greater than or equal to the first time threshold, or when the second counter is greater than or equal to the second time threshold, and the configuration information includes both the first time threshold and the second time threshold.

Referring to fig. 11, it is assumed that after initializing each counter, the terminal device decodes the received PDSCH to obtain 3 ACKs and 2 NACKs in sequence, and it is assumed that the PDSCHs are all initially transmitted, it may determine that the second counter is 2, and it is assumed that the second time threshold indicated in the configuration information is 2, and at this time, the terminal device sends the statistical information to the network device, referring to fig. 10, the terminal device may send the statistical information to the network device through the PUSCH or the PUCCH.

The implementation manner is similar to the above description, except that the relationship between the first counter satisfying the threshold and the second counter satisfying the threshold is "and", and is not described herein again.

It can be understood by those skilled in the art that, in the implementation manners of the first time threshold, the second time threshold, the third time threshold, and the fourth time threshold described above, each time threshold may implement the scheme of this embodiment alone, or may be combined with each other to implement the scheme of this embodiment, where in the implementation manners combined with each other, the limiting conditions of each time threshold may be a "and" relationship or an "or" relationship, which is not limited in this embodiment, and detailed implementation manners thereof are not described again, and specific implementation manners may be obtained by referring to the implementation manners in the above embodiments.

On the basis of the above-described implementation manner of triggering report by the terminal device, in the implementation manner of triggering report by the terminal device, the present embodiment may further add a limit of the first timer, where the first timer is used to indicate the longest time interval for updating the counter.

Next, a description is given, with reference to fig. 12 to fig. 10, of an implementation manner of triggering reporting by a terminal device when a limitation of increasing a first timer is added, where fig. 12 is a schematic diagram of reporting statistical information in combination with the first timer provided in this embodiment of the present application, and fig. 13 is a schematic diagram of reporting statistical information in combination with the first timer provided in this embodiment of the present application.

In this embodiment, the configuration information further includes duration information of a first timer on the basis of the above-described times thresholds, where the first timer is used to define a longest time interval for updating the counter, and after the terminal device receives the PDSCH, the terminal device may start the first timer or restart the first timer, and it may be understood that after the terminal device receives the PDSCH, the counter is updated, so that the first timer may be started or restarted.

And in this embodiment, if the first timer times out, it indicates that the counters are not updated within the time range of the first timer, because the first timer is used to limit the longest time interval for updating the counters, the first counter, the second counter, and the third counter may be reset, for example, may be reset to 0, or may be any preset value,

the counter is reset by setting the first timer, so that the real-time performance of the sent statistical information can be ensured, and the accuracy and the timeliness of the real channel environment of the terminal equipment can be determined according to the statistical information.

Taking the fourth time threshold as an example in conjunction with fig. 12, the first timer is described, referring to fig. 12, and it is assumed that the configuration information includes the first timer T1, and after initializing each counter, the terminal device decodes the received PDSCH to obtain a plurality of ACKs and NACKs in turn, referring to fig. 12, it may be determined that the terminal device starts or restarts T1 every time the terminal device receives the PDSCH.

Referring to the 4 th PDSCH in fig. 12, after receiving the PDSCH, the PDSCH is not received for a period of time, and the PDSCH is not received, the first timer T1 is not started or restarted, thereby causing the first timer T1 to time out, at which the first, second, and third counters are reset.

After one PDSCH is received after the counters are reset, the first timer T1 is started at this time, and then the PDSCH is not received for another period of time, resulting in the first timer T1 being expired, and the first, second, and third counters are reset again.

Then, the terminal device receives 5 PDSCHs, the decoding results of the 5 PDSCHs are sequentially 1 ACK, 1 NACK and 3 ACKs, it may be determined that the sum of the first counter and the second counter is 5, and it is assumed that the fourth count threshold is indicated in the configuration information as 5, and at this time, the sum of the first counter and the second counter is equal to the fourth count threshold, the terminal device sends the statistical information, see fig. 12, the terminal device may send the statistical information to the network device through, for example, a PUSCH or a PUCCH.

Meanwhile, the terminal equipment initializes the counter, continuously updates the counter and compares the counter with the fourth time threshold so as to send the statistical information to the network equipment again when the sum of the first counter and the second counter is larger than or equal to the fourth time threshold.

The first timer is described below with reference to fig. 13 by taking the first time threshold and the second time threshold as an example, and the two times of implementing the timeout of the first timer in fig. 13 are the same as those in fig. 12, and are not described again here.

After the first timer times out for the second time, the terminal device receives 5 PDSCHs, the decoding results of the 5 PDSCHs are sequentially 1 ACK, 1 NACK and 3 ACKs, it may be determined that the first counter is 4, the second counter is 1, and it is assumed that the first count threshold is indicated in the configuration information as 4, and the second count threshold is 2, at this time, the first counter sum is equal to the first count threshold, the terminal device sends statistical information, see fig. 13, and the terminal device may send the statistical information to the network device through the PUSCH or PUCCH.

Meanwhile, the terminal equipment initializes the counter and continuously updates the counter.

It can be understood that the implementation manners of fig. 12 and fig. 13 are two possible implementation manners of the frequency threshold, and the first timer is described, and in an actual implementation process, when the first timer can be applied to any frequency threshold, the implementation manner of the first timer may be correspondingly extended with reference to the above description, and is not described herein again.

On the basis of the implementation manner of triggering report by the terminal device described in the foregoing embodiment, this embodiment may also trigger the terminal device to send the statistical information in combination with the bit error rate in the implementation manner of triggering report by the terminal device.

In another possible implementation manner, the configuration information may include a third block error rate threshold and a fourth block error rate threshold, where the third block error rate threshold and the fourth block error rate threshold are used to define a statistical result of the residual block error rate, and the third block error rate threshold is greater than the fourth block error rate threshold.

In this embodiment, the terminal device may obtain a residual block error rate, where the residual block error rate refers to a ratio of the number of data blocks whose decoding result is still NACK after retransmission to the number of all initially transmitted data blocks; if the residual block error rate is greater than or equal to the third block error rate threshold, the terminal equipment sends statistical information; or, if the residual block error rate is less than or equal to the fourth block error rate threshold, the terminal device sends the statistical information.

In yet another possible implementation manner, the configuration information may include a first block error rate threshold, a second block error rate threshold, a third block error rate threshold, and a fourth block error rate threshold at the same time, where the first block error rate threshold is greater than the second block error rate threshold, and the third block error rate threshold is greater than the fourth block error rate threshold.

In this embodiment, the terminal device may obtain an initial block error rate and/or a residual block error rate, and if the initial block error rate is greater than or equal to a first block error rate threshold, the terminal device sends statistical information; or if the initial block error rate is less than or equal to the second block error rate threshold, the terminal device sends statistical information; or if the residual block error rate is greater than or equal to the third block error rate threshold, the terminal equipment sends statistical information; or, if the residual block error rate is less than or equal to the fourth block error rate threshold, the terminal device sends the statistical information.

That is, when the initial block error rate and the residual block error rate satisfy any one of the block error rate thresholds, the terminal device sends the statistical information.

In another possible implementation manner, the terminal device may be triggered to send the statistical information according to the block error rate and the block error rate threshold alone, which is similar to the above-described implementation manner, but only considering the number of the ACK/NACK of the terminal device is omitted.

By increasing the implementation modes of the block error rate and the block error rate threshold, the flexibility of sending the statistical information can be effectively improved.
