Description

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method, apparatus, device, and chip system.

Background

In non-terrestrial networks, the satellite/aerial devices are at a greater distance from the ground, resulting in insufficient network coverage. The random access message is, for example, message 4 (message.4, msg.4) of the random access procedure, or message B (message.b, msg.b), and Hybrid automatic repeat request ACKnowledgement (HARQ-ACK) feedback of the random access message refers to that, in the random access procedure, after the network device receives and parses the terminal device identifier included in message 3 (message.3, msg.3), msg.4 is sent on a Physical Downlink Shared Channel (PDSCH), msg.4 may also be referred to as a contention resolution message, and the random access procedure is completed after contention resolution succeeds.

If the terminal device successfully decodes the msg.4, a Hybrid automatic repeat request (HARQ) feedback message, which may be referred to as a HARQ-ACK, is sent to the network device, and if the msg.4 is not decoded correctly, the HARQ-ACK is not fed back.

The information transmission method and the device thereof provided by the present disclosure are described in detail below with reference to the accompanying drawings. Fig. 2 is a flowchart illustrating an information transmission method according to an embodiment of the present disclosure, where the method is executed by a terminal device. The information transmission method in this embodiment may be applied to a terminal device, such as a mobile phone, a tablet with a mobile communication function, a smart watch, and the like, without limitation.

As shown in fig. 2, the method may include, but is not limited to, the following steps:

s102: and receiving a random access message sent by the network equipment, wherein the random access message is used for determining a hybrid automatic repeat request acknowledgement message.

In the random access process, the terminal device may receive a random access message, such as msg.4 or msg.b, sent by the network device.

In the embodiment of the present disclosure, the random access message is msg.4, if the terminal device successfully decodes msg.4, the terminal device sends a hybrid automatic repeat request acknowledgement message HARQ-ACK to the network device, and if the terminal device does not decode correctly, the terminal device does not feed back the hybrid automatic repeat request acknowledgement message HARQ-ACK.

In the embodiment of the disclosure, the terminal device may determine the number of times of repeatedly transmitting the HARQ-ACK message, and repeatedly transmit the HARQ-ACK message to the network device based on the number of times of repeatedly transmitting the HARQ-ACK message, so as to enhance the coverage requirement of the HARQ-ACK message, and effectively improve the HARQ-ACK feedback effect of the HARQ-ACK message.

S202: the number of times the hybrid automatic repeat request acknowledgement message is repeatedly transmitted to the network device is determined.

In the embodiment of the present disclosure, after receiving the random access message sent by the network device, the terminal device may determine a suitable number of times for repeatedly transmitting the harq acknowledgement message. In one example, the terminal device may determine the number of times to repeat transmission of the hybrid automatic repeat request acknowledgement message to the network device based on predefined rules.

After determining the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network device, the terminal device may repeatedly transmit the hybrid automatic repeat request acknowledgement message to the network device based on the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message, so as to enhance the coverage requirement of the hybrid automatic repeat request acknowledgement message HARQ-ACK.

The predefined rule may be predefined in a protocol between the terminal device and the network device.

For example, the terminal device may determine the number of times of repeatedly transmitting the HARQ-ACK according to a predefined rule, which is not limited in this regard.

In this embodiment, by receiving a random access message sent by a network device, where the random access message is used to determine a HARQ acknowledgement message and determine the number of times of repeatedly transmitting the HARQ acknowledgement message to the network device, because the number of times of repeatedly transmitting the HARQ acknowledgement message to the network device is determined timely and accurately, the coverage requirement of HARQ-ACK of the HARQ-ACK can be supported to be enhanced, so that the HARQ-ACK feedback effect of the HARQ-ACK is effectively improved.

Fig. 3 is a flowchart illustrating an information transmission method according to an embodiment of the present disclosure, where the method is executed by a terminal device. The information transmission method in this embodiment may be applied to a terminal device, such as a mobile phone, a tablet with a mobile communication function, a smart watch, and the like, without limitation.

As shown in fig. 3, the method may include, but is not limited to, the following steps:

s103: and receiving a random access message sent by the network equipment, wherein the random access message is used for determining a hybrid automatic repeat request acknowledgement message.

For the description of S103, reference may be made to the foregoing embodiments specifically, and details are not repeated here.

S203: and determining the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network equipment according to the measurement result of the downlink signal or the channel.

In this embodiment, the number of times of repeatedly transmitting the harq acknowledgement message to the network device may be determined based on a measurement mode.

For example, in the process of communication between the terminal device and the network device, the network device may send some downlink signals or channels to the terminal device, the terminal device may measure the downlink signals or channels, the obtained measurement result may be used to characterize the quality of the communication network between the network device and the terminal device, and then determine the number of times of repeatedly transmitting the harq acknowledgement message based on the obtained measurement result.

For example, if the downlink signal is measured, the measurement result may be the quality of the downlink signal, and if the channel is measured, the measurement result may be the transmission path loss (abbreviated as path loss) of the channel, which is not limited herein.

For example, the measurement result may be, for example, a Reference Signal Receiving Power (RSRP), a Reference Signal Receiving Quality (RSRQ) representation, or the like, or may also be a range corresponding to a measurement result for characterizing Quality of a communication network between the network device and the terminal device, where the range corresponding to the measurement result may include some possible measurement result values, which is not limited thereto.

In the embodiment of the disclosure, when determining the number of times of repeatedly transmitting the HARQ-ACK to the network device according to the measurement result of the downlink signal or the channel, the downlink signal or the channel may be measured first to obtain a measurement result that can be used for characterizing the quality of a communication network between the network device and the terminal device, and then the number of times of repeatedly transmitting the HARQ-ACK to the network device may be determined based on the measurement result, so that the determined number of times of repeatedly transmitting the HARQ-ACK may be adapted to the quality of the communication network between the network device and the terminal device, and occupation of excessive transmission resources is avoided while effectively supporting the requirement of enhancing the coverage of the HARQ-ACK.

In the information transmission method provided in the embodiment of the present disclosure, the number of times of repeatedly transmitting the harq acknowledgement message has a corresponding relationship with a measurement result of the downlink signal or the channel. In one example, the number of times of repeatedly transmitting the harq acknowledgement message and the measurement result of the downlink signal or channel may be in a one-to-one, many-to-many, or a combination of any two of the above. For example,

the measurement result of a downlink signal or channel corresponds to the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message; and/or the measuring results of at least two downlink signals or channels correspond to the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message; and/or the measurement results of at least two downlink signals or channels correspond to at least two times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message.

The number of times of repeatedly transmitting the harq acknowledgement message corresponds to the measurement result of the downlink signal or channel, which may be shown in table 1, table 2, or table 3, without limitation.

TABLE 1

It is understood that each of the elements of table 1 are independently present and are exemplary listed in the same table, but do not mean that all of the elements in the table must be present according to the simultaneous presence shown in the table. The value of each element is independent of any other element value in table 1. Therefore, it will be understood by those skilled in the art that the values of each of the elements in table 1 are independent embodiments.

TABLE 2

It is understood that each of the elements of table 2 are independently present and are exemplarily listed in the same table, but do not mean that all of the elements in the table must be present according to the presentation in the table at the same time. The value of each element is independent of any other element value in table 2. Therefore, it will be understood by those skilled in the art that the values of each of the elements in table 2 are independent embodiments.

TABLE 3

It is understood that each of the elements in table 3 are independently present and are exemplarily listed in the same table, but do not mean that all of the elements in the table must be present according to the presentation in the table at the same time. The value of each element is independent of any other element value in table 3. Therefore, it will be understood by those skilled in the art that the values of each of the elements in table 3 are independent embodiments.

The measurement result in the table may be an actual measurement value measured by the terminal device, or a quantized value corresponding to the actual measurement value measured by the terminal device, and the quantization method used is not particularly limited, and may be, for example, a 0.5 quantization method.

In the information transmission method provided in the embodiment of the present disclosure, the number of times of repeatedly transmitting the HARQ-ACK message has a corresponding relationship with a range corresponding to a measurement result of the downlink signal or channel, and since the number of times of repeatedly transmitting the HARQ-ACK message is determined according to the corresponding relationship and an obtained measurement result used for characterizing quality of a communication network between the network device and the terminal device, efficiency of determining the number of times of repeatedly transmitting can be effectively improved, and timeliness of message transmission between the network device and the terminal device is effectively improved while a coverage requirement of enhancing HARQ-ACK of the HARQ-ACK message is effectively supported.

As shown in table 1 below, when the measurement result of the terminal device falls between RSRP #2 to RSRP #3, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message is 4.

TABLE 4

It is understood that each of the elements of table 4 are present independently and are exemplarily listed in the same table, but do not mean that all of the elements in the table must be present according to the presentation in the table at the same time. The value of each element is independent of any other element value in table 4. Therefore, it will be understood by those skilled in the art that the values of each of the elements in table 4 are independent embodiments.

The measurement result in the table may be an actual measurement value measured by the terminal device, or may be a quantized value corresponding to the actual measurement value measured by the terminal device, and the quantization method used is not particularly limited, and may be, for example, a 0.5 quantization method.

For example, the correspondence may include, for example: the candidate measurement results and the candidate times corresponding to each candidate measurement result, that is, the candidate measurement results and the candidate times have a one-to-one correspondence relationship, or the candidate measurement results and the candidate times may also have a one-to-many correspondence relationship, when one candidate measurement result corresponds to one candidate time, if it is determined that the measurement result of the downlink signal or channel corresponds to the candidate measurement result, the one candidate time corresponding to the candidate measurement result may be directly used as the number of times for repeatedly transmitting the harq acknowledgment message, or, when one candidate measurement result corresponds to a plurality of candidate times, if it is determined that the measurement result of the downlink signal or channel corresponds to the candidate measurement result, one candidate time may be selected from the plurality of candidate times corresponding to the candidate measurement result as the number of times for repeatedly transmitting the harq acknowledgment message.

For example, the number of times corresponding to the measurement result of the downlink signal or the channel may be preset, and the preset number of times corresponding to the measurement result of the downlink signal or the channel may be used as the number of times for repeatedly transmitting the harq acknowledgment message.

For example, the number of times of repeatedly transmitting the harq acknowledgement message may also be a corresponding relationship with a quantized value of the measurement result of the downlink signal or the channel, for example, the measurement result of the downlink signal or the channel may be quantized, and the number of times of repeatedly transmitting the harq acknowledgement message is determined based on a quantized value, which is not limited herein.

Of course, the number of times of repeatedly transmitting the harq acknowledgement message may also have any other possible form of correspondence with the measurement result of the downlink signal or the channel, and the terminal device may define, in advance, the number of times of repeatedly transmitting the harq acknowledgement message and the correspondence between the measurement result of the downlink signal or the channel based on a protocol with the network device, which is not limited herein.

For example, the correspondence may include, for example: the range corresponding to the multiple candidate measurement results and the candidate number corresponding to the range corresponding to each candidate measurement result, that is, the range corresponding to the candidate measurement result and the candidate number have a one-to-one correspondence relationship, or the range corresponding to the candidate measurement result and the candidate number may also have a one-to-many correspondence relationship, when the range corresponding to one candidate measurement result corresponds to one candidate number, if it is determined that the measurement result of the downlink signal or channel corresponds to the range corresponding to the candidate measurement result (for example, the measurement result is within the range corresponding to one candidate measurement result), one candidate number corresponding to the range corresponding to the candidate measurement result may be directly used as the number of times for repeatedly transmitting the harq acknowledgment message, or, when the range corresponding to one candidate measurement result corresponds to multiple candidate numbers, if it is determined that the measurement result of the downlink signal or channel corresponds to the range corresponding to the candidate measurement result, one candidate number of times may be selected from the multiple candidate numbers in the range corresponding to the candidate measurement result as the number of times for repeatedly transmitting the harq acknowledgment message.

For example, the number of times of adapting to the range corresponding to the measurement result of the downlink signal or the channel may be preset, and the number of times of adapting to the range corresponding to the measurement result of the downlink signal or the channel may be preset as the number of times of repeatedly transmitting the harq acknowledgment message.

For example, the number of times of repeatedly transmitting the harq acknowledgement message may also be that a certain value (such as an average value, a median value, a maximum value, a minimum value, and the like) in a range corresponding to the measurement result of the downlink signal or the channel has a corresponding relationship, for example, a certain value may be selected from a range corresponding to the measurement result of the downlink signal or the channel, and based on the value, the number of times of repeatedly transmitting the harq acknowledgement message is determined, which is not limited herein.

Of course, the number of times of repeatedly transmitting the harq acknowledgement message may also have a corresponding relationship in any other possible form with a range corresponding to the measurement result of the downlink signal or the channel, and the terminal device may define, in advance, the number of times of repeatedly transmitting the harq acknowledgement message with the network device based on a protocol, and a corresponding relationship between the range corresponding to the measurement result of the downlink signal or the channel, which is not limited herein.

That is to say, in the embodiment of the present disclosure, a predefined corresponding relationship between the network device and the terminal device is supported, and the corresponding relationship can be used to characterize an association relationship between a measurement result of a downlink signal or a channel and an adapted retransmission number, so as to support to quickly determine the adapted retransmission number based on an actually obtained measurement result.

In the information transmission method provided in the embodiment of the present disclosure, the corresponding relationship may include: the measurement result used for reference alignment may be referred to as a candidate measurement result, the number of times of adaptation predefined for the candidate measurement result may be referred to as a candidate number of times, the candidate measurement result and the number of times of adaptation candidate may be obtained by experimental simulation determination in advance, and the range used for reference alignment may be referred to as a range corresponding to the candidate measurement result, the number of times of adaptation predefined for the range corresponding to the candidate measurement result may be referred to as a candidate number of times, which is not limited.

For example, the obtained measurement result may be compared with the candidate measurement result in the corresponding relationship, or the obtained measurement result may be compared with the range corresponding to the candidate measurement result in the corresponding relationship to ensure the flexibility of the comparison, and then the candidate times matching the candidate measurement results satisfying the requirement may be used as the times of repeatedly transmitting the harq acknowledgment message, or the candidate times matching the range corresponding to the candidate measurement results satisfying the requirement may be used as the times of repeatedly transmitting the harq acknowledgment message, which is not limited.

For example, if the measurement result is compared with the candidate measurement result in the corresponding relationship, the comparison meets the requirement, which may mean that the measurement result is close to the candidate measurement result, for example, the two are the same, or the difference between the two is within a reasonable error range, which is not limited.

For example, if the range corresponding to the measurement result is compared with the range corresponding to the candidate measurement result in the corresponding relationship, the comparison meets the requirement, which may mean that the range corresponding to the measurement result corresponds to the range corresponding to the candidate measurement result, and the correspondence may be, for example, that the range corresponding to the measurement result intersects with the range corresponding to the candidate measurement result, or that the range corresponding to the measurement result is within the range corresponding to the candidate measurement result, which is not limited.

In this embodiment, by receiving a random access message sent by a network device, where the random access message is used to determine a HARQ acknowledgement message, and determine, according to a measurement result of a downlink signal or a channel, a number of times of repeatedly transmitting the HARQ acknowledgement message to the network device, so that the determined number of times of repeatedly transmitting the HARQ acknowledgement message can be adapted to a communication network quality between the network device and a terminal device, and avoid occupying too many transmission resources while effectively supporting a coverage requirement of enhancing HARQ-ACK of the HARQ acknowledgement message.

Fig. 4 is a flowchart illustrating another information transmission method provided in an embodiment of the present disclosure, where the method is executed by a terminal device. The information transmission method in this embodiment may be applied to a terminal device, such as a mobile phone, a tablet with a mobile communication function, a smart watch, and the like, without limitation.

As shown in fig. 4, the method may include, but is not limited to, the steps of:

s104: and receiving a random access message sent by the network equipment, wherein the random access message is used for determining a hybrid automatic repeat request acknowledgement message.

For the description of S104, reference may be made to the foregoing embodiments specifically, and details are not repeated here.

S204: and determining the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network equipment according to the retransmission times of the reference channel.

In this embodiment, the number of times of repeatedly transmitting the harq acknowledgement message to the network device may be determined based on the reference channel.

For example, a number corresponding to the reference channel may be predefined, and may be referred to as a retransmission number, and then, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network device may be determined according to the retransmission number of the reference channel.

The reference Channel may be a Channel in which the terminal device can determine the retransmission number corresponding to the reference Channel, for example, a Physical Random Access Channel (PRACH) for transmitting the message 1 (message.1, msg.1) in the Random Access process, or the reference Channel may also be a Channel for transmitting the msg.3 in the Random Access process, a Channel for transmitting the message 3 may be a Physical Uplink Shared Channel (PUSCH), and when determining the retransmission number of the PRACH, the terminal device may determine the retransmission number of the PRACH by measuring a reference signal received power RSRP level, that is, determining the retransmission number of the PRACH according to different coverage levels, and when determining the retransmission number of the msg.3, the terminal device may determine the retransmission number based on an indication of a Random Access Response (RAR), which is not limited.

That is to say, in the embodiment of the present disclosure, it is supported to determine the number of times of repeatedly transmitting the harq acknowledgement message to the network device according to the retransmission number of the reference channel, so that the number of times of repeatedly transmitting the harq acknowledgement message can be flexibly determined, the application range of the information transmission method can be effectively extended, and the practicability of the information transmission method is improved.

In the information transmission method provided in the embodiment of the present disclosure, the reference channel includes at least one of: a physical random access channel PRACH; the channel for transmitting the message 3 may not be limited to the type of the reference channel.

After the retransmission times related to the reference channel is determined, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network device is determined, so that the determined number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message can be adapted to the reference channel with the determined retransmission times, and the repeated transmission process of the hybrid automatic repeat request acknowledgement message and the repeated transmission process of other reference channels can be effectively balanced while the coverage requirement of enhancing the hybrid automatic repeat request acknowledgement message HARQ-ACK is effectively supported.

According to the information transmission method provided by the embodiment of the disclosure, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message has a corresponding relation with the number of times of retransmitting the reference channel, the determination efficiency of the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message can be effectively supported, and the timeliness of message transmission between the network equipment and the terminal equipment is effectively improved while the coverage requirement of enhancing the hybrid automatic repeat request acknowledgement message HARQ-ACK is effectively supported.

The information transmission method provided in the embodiments of the present disclosure determines, according to the number of retransmissions, the number of times of repeatedly transmitting the harq acknowledgment message to the network device, and may also determine the number of times of repeatedly transmitting the harq acknowledgment message predefined for the terminal device, where the number of times of retransmission of the reference channel has a corresponding relationship, where the corresponding relationship may include: and determining the candidate times corresponding to the retransmission times of the reference channel from the corresponding relation, and taking the corresponding candidate times as the times for repeatedly transmitting the hybrid automatic repeat request acknowledgement message.

That is to say, in the embodiment of the present disclosure, a predefined corresponding relationship between the network device and the terminal device is supported, where the predefined corresponding relationship can be used to represent an adaptation relationship between the retransmission times of the reference channel and the times of repeatedly transmitting the harq acknowledgment messages, so as to support the retransmission times based on the reference channel and quickly determine the times of the adapted harq acknowledgment messages.

For example, the number of times of repeatedly transmitting the harq acknowledgement message corresponds to the number of times of retransmission of the reference channel. For example, the hybrid automatic repeat request acknowledgement message is repeatedly transmitted the same number of times as the retransmission times of the reference channel. Or, the number of times of repeatedly transmitting the harq acknowledgement message = the number of retransmissions + a preset value of the reference channel; or, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message = preset value than the number of times of retransmission of the reference channel. Wherein the predetermined value is a positive integer. For example, the preset value =1, the number of times of repeatedly transmitting the harq acknowledgement message is 1 greater than the number of times of retransmitting the reference channel, or the number of times of repeatedly transmitting the harq acknowledgement message is 1 less than the number of times of retransmitting the reference channel, which may be predefined as any other possible corresponding manner, without limitation.

In this embodiment, by receiving a random access message sent by a network device, where the random access message is used to determine a hybrid automatic repeat request acknowledgement message, and determine, according to a retransmission number of a reference channel, a number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network device, and support determining, according to the retransmission number of the reference channel, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network device, where the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message can be adapted to the reference channel for which the retransmission number has been determined, and while effectively supporting a coverage requirement of enhancing HARQ-ACK of the hybrid automatic repeat request acknowledgement message, a repeat transmission process of the hybrid automatic repeat request acknowledgement message and a repeat transmission process of another reference channel can be effectively balanced. The method can also flexibly determine the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message, effectively expand the application range of the information transmission method and improve the practicability of the information transmission method.

Fig. 5 is a flowchart illustrating another information transmission method provided in an embodiment of the present disclosure, where the method is executed by a terminal device. The information transmission method in this embodiment may be applied to a terminal device, such as a mobile phone, a tablet with a mobile communication function, a smart watch, and the like, without limitation.

As shown in fig. 5, the method may include, but is not limited to, the following steps:

s105: and receiving a random access message sent by the network equipment, wherein the random access message is used for determining a hybrid automatic repeat request acknowledgement message.

For the description of S105, reference may be made to the foregoing embodiments specifically, and details are not repeated here.

S205: and determining the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message to the network equipment according to the type of the access network of the terminal equipment.

In the embodiment of the present disclosure, the number of times of repeatedly transmitting the harq acknowledgement message to the network device may also be determined based on the type of the access network of the terminal device.

In the information transmission method provided in the embodiment of the present disclosure, the access network type includes at least one of the following: non-Terrestrial Network (NTN), satellite communication Network, and Terrestrial Network (TN), without limitation.

For example, the number of times of adaptation may be configured in advance for each network type, and then the number of times of adaptation is obtained as the number of times of repeatedly transmitting the harq acknowledgement message according to the actual access network type of the terminal device, which is not limited.

For example, when determining the access network type, the terminal device may determine the type based on a frequency point search, or may determine, by using a specific field in the System Information Block message 1 (System Information Block1, SIB 1), that the specific field is, for example, cell-barredNTN, and if the specific field exists, it indicates that the access network type of the terminal device is an NTN network, or may determine, by using satellite ephemeris Information in SIB19, an access satellite orbit type, for example, a low-orbit satellite, a geostationary satellite, or the like, which is not limited thereto.

After the type of the access network of the terminal device is determined, the number of times of repeatedly transmitting the harq acknowledgement message to the network device may be determined according to the type of the access network, for example, the number of times of predefining adaptation to the type of the access network is determined as the number of times of repeatedly transmitting the harq acknowledgement message, so that the determined number of times of repeatedly transmitting the harq acknowledgement message is adapted to the actual type of the access network of the terminal device, thereby flexibly determining the number of times of repeatedly transmitting the harq acknowledgement message, effectively extending the application range of the information transmission method, and improving the practicability of the information transmission method.

The information transmission method provided by the embodiment of the present disclosure determines, according to an access network type, a number of times of repeatedly transmitting a hybrid automatic repeat request acknowledgement message to a network device, where the number of times of repeatedly transmitting a hybrid automatic repeat request acknowledgement message predefined for a terminal device may be determined, and the number of times of repeatedly transmitting a hybrid automatic repeat request acknowledgement message has a corresponding relationship with the access network type of the terminal device, where the corresponding relationship may include: the multiple candidate network types and the candidate times corresponding to the candidate network types can determine the candidate network types same as the access network types from the corresponding relation, and the candidate times corresponding to the same candidate network types are used as the times for repeatedly transmitting the hybrid automatic repeat request acknowledgement message, so that the determination efficiency of the repeated transmission times can be effectively improved, and the timeliness of message transmission between the network equipment and the terminal equipment can be effectively improved while the coverage requirement of enhancing the hybrid automatic repeat request acknowledgement message HARQ-ACK is effectively supported.

That is to say, in the embodiment of the present disclosure, the number of times of predefined harq acknowledgement messages is predefined between the network device and the terminal device, and the number of times of harq acknowledgement messages is predefined by the network device, where the predefined harq acknowledgement messages has a corresponding relationship with an access network type of the terminal device, and the corresponding relationship can be used to characterize the access network type of the terminal device, and an adaptive relationship between the number of times of harq acknowledgement messages is repeatedly transmitted, so as to support fast determining the number of times of harq acknowledgement messages that are adapted based on the network type that the terminal device accesses.

For example, if the type of the access network of the terminal device is the non-terrestrial network NTN, the number of times of repeatedly transmitting the harq acknowledgement message may be determined to be X1, and if the type of the access network of the terminal device is a satellite (satellite) communication network, the number of times of repeatedly transmitting the harq acknowledgement message may be determined to be X2, where X1 and X2 may be the same or different, and may be predefined as any possible number of times of repeatedly transmitting the harq acknowledgement message according to actual communication requirements, which is not limited.

In this embodiment, by receiving a random access message sent by a network device, where the random access message is used to determine a HARQ acknowledgement message, and determine, according to an access network type of a terminal device, a number of times of retransmission of the HARQ acknowledgement message to the network device, and while effectively supporting a coverage requirement of HARQ-ACK, the determined number of times of retransmission of the HARQ acknowledgement message is adapted to an actual access network type of the terminal device, so as to flexibly determine the number of times of retransmission of the HARQ acknowledgement message, thereby effectively extending an application range of an information transmission method and improving the practicability of the information transmission method.

The information transmission method provided by the embodiment of the disclosure determines the number of times of repeatedly transmitting the harq acknowledgement message to the network device, and may also determine the number of times of repeatedly transmitting the harq acknowledgement message to the network device according to the type of the terminal device, so that the determined number of times of repeatedly transmitting the harq acknowledgement message is adapted to the type of the terminal device, thereby flexibly determining the number of times of repeatedly transmitting the harq acknowledgement message, effectively extending the application range of the information transmission method, and improving the practicability of the information transmission method.

According to the information transmission method provided by the embodiment of the disclosure, the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message has a corresponding relation with the type of the terminal device, and the number of times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message matched with the type of the terminal device can be quickly and accurately determined.

In the information transmission method provided by the embodiment of the present disclosure, the type of the terminal device includes at least one of the following: a power type; the type of antenna.

For example, the power type of the terminal device is, for example, a high power terminal device UE, a normal power terminal device UE (23 decibel relative to one milliwatt, dBm)).

The number of times of repeatedly transmitting the harq acknowledgement message has a corresponding relationship with the power type of the terminal device, and may be, for example, 1 for the number of times of repeatedly transmitting the harq acknowledgement message predefined for the high-power terminal device UE, or 4 for the number of times of repeatedly transmitting the harq acknowledgement message predefined for the normal power terminal device UE (23 dBm), or may be set to any other possible corresponding form, and the corresponding relationship may not be limited.

For example, the antenna type of the Terminal device may be, for example, a Very Small antenna earth station (VSAT) antenna, a linearly polarized dipole antenna, or the like.

The number of times of repeatedly transmitting the harq acknowledgment message and the corresponding relationship between the antenna type of the terminal device may be, for example, if the antenna type of the terminal device is a VSAT antenna, the number of times of repeatedly transmitting the harq acknowledgment message is 1, and if the antenna type of the terminal device is a linearly polarized dipole antenna, the number of times of repeatedly transmitting the harq acknowledgment message is 4, and of course, the number of times of repeatedly transmitting the harq acknowledgment message and the corresponding relationship between the antenna type of the terminal device may also be set to any other possible corresponding form, and the corresponding relationship may not be limited.

In the embodiment of the present disclosure, the above antenna type and power type are merely examples, and the power type and antenna type of the terminal device may not be limited.

According to the information transmission method provided by the embodiment of the disclosure, the terminal device can also repeatedly transmit the hybrid automatic repeat request acknowledgement message to the network device according to the times of repeatedly transmitting the hybrid automatic repeat request acknowledgement message, so that the coverage requirement of the hybrid automatic repeat request acknowledgement message HARQ-ACK can be enhanced, and the feedback effect of the hybrid automatic repeat request acknowledgement message HARQ-ACK can be effectively improved.

In the following description of the embodiments, the same or corresponding terms and method steps as those in the above embodiments may be referred to the above embodiments, and are not described herein again.

Fig. 6 is a flowchart illustrating a message transmission method according to an embodiment of the disclosure, where the method is performed by a network device.

As shown in fig. 6, the method may include, but is not limited to, the following steps:

s106: and sending a random access message to the terminal equipment, wherein the random access message is used for determining the hybrid automatic repeat request acknowledgement message.

Wherein the hybrid automatic repeat request acknowledgement message is used to determine the number of times it is repeatedly transmitted.

In the random access process, the network device may send a random access message, such as msg.4 or msg.b, to the terminal device.

S206: and receiving the hybrid automatic repeat request confirmation message repeatedly transmitted by the terminal equipment, wherein the times of the repeatedly transmitted hybrid automatic repeat request confirmation message are determined by the terminal equipment.

In the embodiment of the present disclosure, the HARQ-ACK message may be used by the terminal device to determine the number of times of repeatedly transmitting the HARQ-ACK message, for example, the terminal device may determine the number of times of repeatedly transmitting the HARQ-ACK message, and repeatedly transmit the HARQ-ACK message to the network device based on the number of times of repeatedly transmitting the HARQ-ACK message, so that the network device may receive the HARQ-ACK message repeatedly transmitted by the terminal device, so as to enhance the coverage requirement of the HARQ-ACK message, and effectively improve the HARQ-ACK feedback effect of the HARQ-ACK message.

In this embodiment, a random access message is sent to a terminal device, where the random access message is used to determine a hybrid automatic repeat request acknowledgement message and receive the hybrid automatic repeat request acknowledgement message repeatedly transmitted by the terminal device, where the number of times of the hybrid automatic repeat request acknowledgement message repeatedly transmitted is determined by the terminal device, and the coverage requirement of enhancing the HARQ-ACK of the hybrid automatic repeat request acknowledgement message can be supported, so that the HARQ-ACK feedback effect of the hybrid automatic repeat request acknowledgement message is effectively improved.

Fig. 7 is a flowchart illustrating another message transmission method provided by an embodiment of the present disclosure, where the method is performed by a network device.

As shown in fig. 7, the method may include, but is not limited to, the following steps:

s107: the times of the hybrid automatic repeat request acknowledgement message which is transmitted repeatedly and the measurement result of the downlink signal or the channel have a corresponding relation; or, the number of times of the hybrid automatic repeat request acknowledgement message being repeatedly transmitted has a corresponding relationship with a range corresponding to the measurement result of the downlink signal or the channel.

For example, the correspondence may include, for example: the candidate measurement results and the candidate times corresponding to each candidate measurement result, that is, the candidate measurement results and the candidate times have a one-to-one correspondence relationship, or the candidate measurement results and the candidate times may also have a one-to-many correspondence relationship, when one candidate measurement result corresponds to one candidate time, if it is determined that the measurement result of the downlink signal or channel corresponds to the candidate measurement result, the one candidate time corresponding to the candidate measurement result may be directly used as the number of times of the hybrid automatic repeat request acknowledgement message for repeat transmission, or, when one candidate measurement result corresponds to a plurality of candidate times, if it is determined that the measurement result of the downlink signal or channel corresponds to the candidate measurement result, one candidate time may be selected from the plurality of candidate times corresponding to the candidate measurement result as the number of times of the hybrid automatic repeat request acknowledgement message for repeat transmission.

For example, the number of times corresponding to the measurement result of the downlink signal or the channel may be preset, and the preset number of times corresponding to the measurement result of the downlink signal or the channel may be used as the number of times of the hybrid automatic repeat request acknowledgement message that is repeatedly transmitted.

For example, the number of times of the harq acknowledgement message being retransmitted may also be a value corresponding to a quantized value of a measurement result of the downlink signal or the channel, for example, the measurement result of the downlink signal or the channel may be quantized, and the number of times of the harq acknowledgement message being retransmitted is determined based on a value obtained by quantization, which is not limited.

Of course, the number of times of the harq acknowledgement message that is repeatedly transmitted may also have any other possible form of correspondence with the measurement result of the downlink signal or channel, and the terminal device may define, in advance, the number of times of the harq acknowledgement message that is repeatedly transmitted based on a protocol with the network device and the correspondence with the measurement result of the downlink signal or channel, which is not limited herein.

For example, the correspondence may include, for example: the range corresponding to the multiple candidate measurement results and the candidate number corresponding to the range corresponding to each candidate measurement result, that is, the range corresponding to the candidate measurement result and the candidate number have a one-to-one correspondence relationship, or the range corresponding to the candidate measurement result and the candidate number may also have a one-to-many correspondence relationship, when the range corresponding to one candidate measurement result corresponds to one candidate number, if it is determined that the measurement result of the downlink signal or channel corresponds to the range corresponding to the candidate measurement result (for example, the measurement result is within the range corresponding to one candidate measurement result), one candidate number corresponding to the range corresponding to the candidate measurement result may be directly used as the number of the hybrid automatic repeat request acknowledgement message that is repeatedly transmitted, or, when the range corresponding to one candidate measurement result corresponds to multiple candidate numbers, if it is determined that the measurement result of the downlink signal or channel corresponds to the range corresponding to the candidate measurement result, one candidate number of the candidate number may be selected from the multiple candidate numbers in the range corresponding to the candidate measurement result as the number of the hybrid automatic repeat request acknowledgement message that is repeatedly transmitted.

For example, the number of times of adapting to the range corresponding to the measurement result of the downlink signal or the channel may be preset, and the number of times of adapting to the range corresponding to the measurement result of the downlink signal or the channel may be preset as the number of times of the harq acknowledgment message that is repeatedly transmitted.

For example, the number of times of the hybrid automatic repeat request acknowledgement message being repeatedly transmitted may also be that a certain value (such as an average value, a median value, a maximum value, a minimum value, and the like) in a range corresponding to the measurement result of the downlink signal or the channel has a corresponding relationship, for example, a certain value may be selected from a range corresponding to the measurement result of the downlink signal or the channel, and the number of times of the hybrid automatic repeat request acknowledgement message being repeatedly transmitted is determined based on the value, which is not limited herein.

Of course, the number of times of the harq acknowledgement message that is repeatedly transmitted may also have a corresponding relationship in any other possible form with a range corresponding to the measurement result of the downlink signal or channel, and the terminal device may define, in advance, the number of times of the harq acknowledgement message that is repeatedly transmitted based on a protocol with the network device, and a corresponding relationship between the range corresponding to the measurement result of the downlink signal or channel, which is not limited to this.

In this embodiment, the number of times of the harq acknowledgement message that is repeatedly transmitted has a corresponding relationship with a measurement result of a downlink signal or a channel; or, the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted has a corresponding relationship with the range corresponding to the measurement result of the downlink signal or the channel, so that the determination efficiency of the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted can be effectively improved, and the timeliness of message transmission between the network equipment and the terminal equipment is effectively improved while the coverage requirement of the hybrid automatic repeat request acknowledgement message HARQ-ACK is effectively supported and enhanced.

Fig. 8 is a flowchart illustrating another message transmission method provided by an embodiment of the present disclosure, where the method is performed by a network device.

As shown in fig. 8, the method may include, but is not limited to, the following steps:

s108: the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted has a corresponding relation with the number of times of retransmission of the reference channel.

That is to say, in the embodiment of the present disclosure, a predefined corresponding relationship between the network device and the terminal device is supported, where the predefined corresponding relationship can be used to represent an adaptation relationship between the retransmission times of the reference channel and the times of the harq acknowledgement messages that are repeatedly transmitted, so as to support fast determining the times of the harq acknowledgement messages that are adapted and repeatedly transmitted based on the retransmission times of the reference channel.

For example, the number of hybrid automatic repeat request acknowledgement messages that are repeatedly transmitted corresponds to the number of retransmissions of the reference channel. For example, the number of hybrid automatic repeat request acknowledgement messages that are repeatedly transmitted is the same as the number of retransmissions of the reference channel. Or the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted = the number of times of retransmission + a preset value of the reference channel; or, the number of hybrid automatic repeat request acknowledgement messages that are repeatedly transmitted = number of retransmissions-preset value than the reference channel. Wherein the preset value is a positive integer. For example, the preset value =1, the number of times of the hybrid automatic repeat request acknowledgement message being repeatedly transmitted is 1 greater than the number of times of retransmission of the reference channel, or the number of times of the hybrid automatic repeat request acknowledgement message being repeatedly transmitted is 1 less than the number of times of retransmission of the reference channel.

In the message transmission method provided by the embodiment of the present disclosure, the reference channel includes at least one of the following: physical Random Access Channel (PRACH); the channel on which message 3 is transmitted is not limited.

The reference Channel may be a Channel for which the terminal device can determine the retransmission number corresponding to the reference Channel, such as a Physical Random Access Channel (PRACH) for transmitting the message 1 (message.1, msg.1) in the Random Access procedure, or the reference Channel may be a Channel for transmitting msg.3 in the Random Access procedure, the Channel for transmitting the message 3 may be a Physical Uplink Shared Channel (PUSCH), when determining the retransmission number of the PRACH, the terminal device may determine the retransmission number of the PRACH by measuring a reference signal received power RSRP level, that is, determining the retransmission number of the PRACH according to different coverage levels, when determining the retransmission number of the msg.3, the terminal device may determine the retransmission number based on an indication of a Random Access Response (RAR), which is not limited.

In this embodiment, since the number of times of the HARQ-ACK is repeatedly transmitted and the number of times of retransmission of the reference channel have a corresponding relationship, the efficiency of determining the number of times of the HARQ-ACK can be effectively improved, and the timeliness of message transmission between the network device and the terminal device is effectively improved while the coverage requirement of the HARQ-ACK is effectively supported.

Fig. 9 is a flowchart illustrating another message transmission method provided by an embodiment of the present disclosure, where the method is performed by a network device.

As shown in fig. 9, the method may include, but is not limited to, the steps of:

s109: the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted has a corresponding relation with the type of the access network of the terminal equipment.

That is to say, in the embodiment of the present disclosure, the number of times of hybrid automatic repeat request acknowledgement messages predefined for repeat transmission between the network device and the terminal device is supported, and the number of times of hybrid automatic repeat request acknowledgement messages predefined for repeat transmission between the network device and the terminal device has a corresponding relationship with an access network type of the terminal device, where the corresponding relationship can be used to characterize the access network type of the terminal device, and an adaptation relationship between the number of times of hybrid automatic repeat request acknowledgement messages for repeat transmission is supported, so as to support fast determination of the number of times of adapted hybrid automatic repeat request acknowledgement messages for repeat transmission based on the network type accessed by the terminal device.

For example, if the access network type of the terminal device is the non-terrestrial network NTN, the number of times of the hybrid automatic repeat request acknowledgement message for the repeat transmission may be determined to be X1, and if the access network type of the terminal device is a satellite (satellite) communication network, the number of times of the hybrid automatic repeat request acknowledgement message for the repeat transmission may be determined to be X2, where X1 and X2 may be the same or different, and may be predefined as the number of times of any possible hybrid automatic repeat request acknowledgement message for the repeat transmission according to an actual communication requirement, which is not limited.

In the message transmission method provided in the embodiment of the present disclosure, the access network type includes at least one of the following: non-Terrestrial Network (NTN), satellite communication Network, and Terrestrial Network (TN), without limitation.

In this embodiment, since the number of times of the HARQ acknowledgement message for retransmission has a corresponding relationship with the type of the access network of the terminal device, the determined number of times of the HARQ acknowledgement message for retransmission is adapted to the type of the network to which the terminal device is actually accessed while the coverage requirement of the HARQ-ACK for the enhanced HARQ-ACK is effectively supported, so that the number of times of the HARQ acknowledgement message for retransmission is flexibly determined, the application range of the message transmission method can be effectively extended, and the practicability of the message transmission method is improved.

The message transmission method provided by the embodiment of the disclosure determines the number of times of the harq acknowledgement message repeatedly transmitted to the network device, and may also determine the number of times of the harq acknowledgement message repeatedly transmitted to the network device according to the type of the terminal device, so that the determined number of times of the harq acknowledgement message repeatedly transmitted is adapted to the type of the terminal device, thereby flexibly determining the number of times of the harq acknowledgement message repeatedly transmitted, effectively extending the application range of the message transmission method, and improving the practicability of the message transmission method.

According to the message transmission method provided by the embodiment of the disclosure, the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted has a corresponding relation with the type of the terminal device, and the number of times of the hybrid automatic repeat request acknowledgement message which is repeatedly transmitted and is adaptive to the type of the terminal device can be rapidly and accurately determined.

In the message transmission method provided by the embodiment of the present disclosure, the type of the terminal device includes at least one of the following: a power type; the type of antenna.

For example, the power type of the terminal device is, for example, a high power terminal device UE, a normal power terminal device UE (23 decibel relative to one milliwatt, dBm).

The number of times of the harq acknowledgement message for retransmission has a corresponding relationship with the power type of the terminal device, and may be, for example, 1 for the number of times of the harq acknowledgement message for retransmission predefined for the high power terminal device UE, or 4 for the number of times of the harq acknowledgement message for retransmission predefined for the general power terminal device UE (23 dBm).

The corresponding relationship between the number of the harq acknowledgement messages that are repeatedly transmitted and the antenna type of the terminal device may be, for example, if the antenna type of the terminal device is a VSAT antenna, the number of the harq acknowledgement messages that are repeatedly transmitted is 1, and if the antenna type of the terminal device is a linearly polarized dipole antenna, the number of the harq acknowledgement messages that are repeatedly transmitted is 4, and of course, the corresponding relationship between the number of the harq acknowledgement messages that are repeatedly transmitted and the antenna type of the terminal device may also be set to any other possible corresponding form, and the corresponding relationship may not be limited.
