Detailed Description

Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.

Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As described above, configuring the number of repeated transmissions of the PUCCH in a static manner may cause resource waste. For example, the PUCCH has been correctly received after a certain retransmission, but the terminal may continue to retransmit the PUCCH until the configured number of retransmissions is reached.

On the other hand, the transmission of the PUSCH (Physical Uplink Shared Channel) may be affected, resulting in information loss. For example, when PUCCH and PUSCH overlap on transmission resources, PUSCH transmissions may be dropped. Therefore, redundant PUCCH repetition transmission may adversely affect the transmission performance of the PUSCH.

In view of the above technical problems, the present disclosure dynamically indicates the number of times of PUCCH retransmission, so that a base station can flexibly configure PUCCH retransmission, thereby improving uplink resource utilization efficiency and transmission performance. For example, the technical solution of the present disclosure can be realized by the following embodiments.

Fig. 1 shows a flow chart of some embodiments of a control method of channel repeat transmission of the present disclosure.

As shown in fig. 1, in step 110, a first candidate transmission number of a channel and a bit size indicated by an information field in DCI are configured. For example, the channel is PUCCH.

In some embodiments, the bit size occupied by the indication information field and the first candidate transmission number of the channel are configured through RRC signaling.

In some embodiments, an indication information field "PUCCH retransmission times" is added to the DCI to indicate the current number of repeated transmissions of the PUCCH. For example, the bit size occupied by the indication information field may be configured by RRC signaling as 0, 1, N > 1.

In step 120, in response to transmitting information through the channel, a bit size occupied by the indication information field is obtained, and it is determined whether the bit size is 0.

In step 130, configuring the number of repeated transmissions of the channel as a first candidate number of transmissions in case of a bit size of 0; and under the condition that the bit size is not 0, configuring the content in the indication information field according to the bit size and the current channel measurement result, wherein the content is used for indicating the repeated transmission times of the channel.

In some embodiments, when the number of bits of the "PUCCH repetition times" is configured to be 0, the PUCCH repetition transmission number adopts the previously RRC-configured repetition transmission number (first candidate transmission number); when the number of bits of the "PUCCH repetition times" is configured to 1, the PUCCH repetition transmission number is determined according to the "indirect indication scheme"; when the number of bits of the "PUCCH repetition times" is configured to be N, the PUCCH repetition transmission number is determined according to the "direct indication scheme".

In some embodiments, in a case where the bit size is not 0 and is a first number, the content in the indication information field is configured as the first identity or the second identity according to a current channel measurement result. The first flag (e.g., "0") is used to indicate that the number of repeated transmissions of the channel is configured as a first candidate number of transmissions, and the second flag (e.g., "1") is used to indicate that the number of repeated transmissions of the channel is configured as a second candidate number of transmissions. For example, the first number is 1 bit, and the first identifier or the second identifier occupies 1 bit.

For example, if the current channel measurement result (such as performance scores determined according to various channel performance indicators) is greater than a preset threshold, that is, the current channel quality is better, the second candidate transmission number may be configured to be smaller than the first candidate transmission number, so as to reduce resource waste; the current channel measurement result is less than or equal to the preset threshold, that is, the current channel quality is poor, the second candidate transmission number may be configured to be greater than the first candidate transmission number, so as to improve the reliability of information transmission.

In some embodiments, for the "indirect indication scheme", the RRC signaling may configure different numbers of repeated transmissions for PUCCH formats 1, 3, 4 as the first candidate number of transmissions. And dynamically adjusting the repeated transmission times of the PUCCH through the newly added PUCCH repetition times in the DCI.

For example, the "PUCCH repetition times" of the "indirect indication scheme" occupies only 1 bit, and DCI overhead can be reduced compared to the "direct indication scheme".

In some embodiments, the value (content) of the added indication information field "PUCCH reproduction times" may be "0" or "1". The current number of repeated transmissions of the PUCCH may be jointly determined according to the RRC-configured number of repeated transmissions and the value of the indication information field.

For example, the current number of repeated transmissions of the PUCCH may be determined by the embodiment in table 1.

TABLE 1

As shown in table 1, the RRC-configured PUCCH retransmission times are 2, 4, and 8. Similar configuration can be done if the RRC can configure other PUCCH retransmission times.

When the first candidate transmission times of the RRC signaling configuration instruction is a default value, if the value of the indication information field is a first identifier, configuring the current repeated transmission times of the PUCCH as 1 time; and if the value of the indication information field is the second identifier, configuring the current repeated transmission times of the PUCCH as times other than 1 time according to the channel measurement result.

In some embodiments, in the case where the bit size is not 0 and is the second number, the content in the indication information field is configured as the third candidate transmission number according to the current channel measurement result. That is, the "direct indication scheme" directly configures a value indicating an information field as a specific value of the current number of repeated transmissions of the PUCCH.

For example, if the current channel measurement result is greater than the preset threshold, that is, the current channel quality is better, the third candidate transmission number may be configured to be smaller than the first candidate transmission number, so as to reduce resource waste; the current channel measurement result is less than or equal to the preset threshold, that is, the current channel quality is poor, the third candidate transmission number may be configured to be greater than the first candidate transmission number, so as to improve the reliability of information transmission.

For example, the second number of the "direct indication scheme" is greater than 1 bit, and the second number is determined according to the number of the kinds of the candidate transmission times. The second number may be N ═ log₂K]And K is the number of the types of the candidate transmission times.

In some embodiments, the DCI configured with the indication information field is transmitted to the terminal side, so that the terminal side decodes the DCI to determine the number of repeated transmissions of the channel.

In the above embodiment, the base station may flexibly configure the current number of times of repeated transmission of the PUCCH according to the current measurement result of the channel, thereby improving the uplink resource utilization efficiency and transmission performance.

The direct indication scheme has more flexibility; the DCI overhead of the "indirect indication scheme" is small. A more appropriate scheme may be selected according to the actual scenario.

Fig. 2 shows a flow chart of further embodiments of the disclosed control method of channel repeat transmission.

As shown in fig. 2, in step 210, the base station configures, through RRC signaling, a bit size occupied by a DCI new added indication information field "PUCCH repetition times"; the number of repeated transmissions of the PUCCH format is configured to be 8 times (i.e., the first candidate transmission number) by an nrofllots parameter in a PUCCH-Configuration IE (Configuration Information Element).

In step 220, the bit size occupied by the "PUCCH repetition times" is determined.

In step 230, if the bit size of the "PUCCH repetition times" is 0, it indicates that the current number of repeated transmissions of the PUCCH is configured to be the RRC-configured number of repeated transmissions (i.e., 8).

In step 240, if the bit size of the "PUCCH repetition times" is 1, "an" indirect indication scheme "represented by 1 bit is employed.

For example, if the base station finds that the current channel condition is good (for example, the channel measurement result exceeds a preset threshold) through uplink channel measurement of the user, the PUCCH can be correctly received without repeating PUCCH transmission for 8 times.

In this case, to avoid resource waste, the value of the DCI addition information field "PUCCH repetition time" is configured to be 1, and the second candidate transmission number is adopted and is smaller than the first candidate transmission number. In this way, the current number of repeated transmissions of the PUCCH can be reduced to avoid resource waste.

In step 250, if the bit size of the "PUCCH retransmission times" is N, the "direct indication scheme" represented by N bits is employed.

For example, if the base station finds that the current channel condition is good through uplink channel measurement of the user, the PUCCH can be correctly received without 8 times of PUCCH repeat transmission.

In this case, to avoid resource waste, a more suitable PUCCH repetition transmission number (i.e., a third candidate transmission number) is directly configured through the DCI addition information field "PUCCH repetition time", and the third candidate transmission number is smaller than the first candidate transmission number.

In some embodiments, the user decodes the DCI transmitted from the base station side at the terminal side, and determines the number of PUCCH retransmission times according to the number of bits occupied by the "PUCCH retransmission times" and the corresponding bit value. For example, the DCI may be received and decoded by the terminal.

In some embodiments, the second configuration unit 32 configures the content in the indication information field as the first identity or the second identity according to the current channel measurement result in case that the bit size is the first number. The first flag is used for indicating the configuration of the repeated transmission times of the channel as a first candidate transmission times, and the second flag is used for indicating the configuration of the repeated transmission times of the channel as a second candidate transmission times.

For example, the first number is 1 bit, and the first identifier or the second identifier occupies 1 bit.
