Description

Method and device for early termination of transmission

Technical field

The present disclosure relates to the field of communications, and in particular, to a method and apparatus for early termination of transmission.

Background technique

3GPP (3rd Generation Partnership Project) release 16 (version 16) proposes that a PDCCH (Physical Downlink Control Channel) can be used to continuously schedule multiple uplink or downlink TBs (Transmission Blocks, Data block), as shown in Figure 1A. Considering that there may be repeated transmissions in MTC (Machine Type Communication), the scheduling method is shown in Figure 1B.

In the related art, the base station may configure a maximum number of repeated transmissions of each TB for the terminal according to the channel status of the terminal. However, due to factors such as channel measurement error and channel fluctuation, the terminal may have successfully demodulated the current TB when the total number of repeated uploads of each TB is less than the maximum number of times. However, the terminal will continue to upload the current TB repeatedly until the total number of times reaches the maximum number of times, as shown in FIG. 2. This brings additional MTC terminal power consumption.

For the above step 103, if the total number of times that the terminal repeatedly uploads the first data block does not reach the first target number of times, the base station determines that the first data block is successfully demodulated, and the base station may send the target DCI (Downlink Control Information) to the terminal, and after the terminal terminates the upload of the first data block to the base station in advance according to the target DCI, the terminal repeatedly uploads the second data block to the base station.

In an embodiment, referring to FIG. 4, FIG. 4 is a flowchart of another early termination transmission method according to the embodiment shown in FIG. 3. After step 103, the method may further include:

In step 104, the second data block repeatedly uploaded by the terminal is started to be received in the next time unit of the target time unit.

In the embodiment of the present disclosure, the base station may determine the target time unit in any of the following manners:

In a first manner, a sum of a time unit number corresponding to a start time unit and a time unit occupied by the first target number of times is used as a target time unit number, and a time unit corresponding to the target time unit number is used as the Target time unit.

In this way, assuming that the starting time unit number is 0 and the total time unit occupied by the first target number is 32, the target time unit number is 0 + 32 = 32, and the 32nd time unit is the target time unit.

In a second manner, a sum of a time unit number of a specified time unit and a target time unit offset is used as a target time unit number, and a time unit corresponding to the target time unit number is used as the target time unit.

The specified time unit is the last time unit when the terminal receives the target DCI. The base station may use any of the following methods to determine the target time unit offset;

In a first manner, a pre-defined time unit offset in a communication protocol is used as the target time unit offset.

In this way, the base station can directly use the pre-defined time unit offset in the communication protocol as the target time unit offset.

In a second manner, the target time unit offset is configured for the terminal through the first preset signaling or the second preset signaling.

Optionally, the first preset signaling may be high-level RRC (Radio Resource Control) signaling. The second preset signaling may be MAC (Media Access Control) signaling at the physical layer.

The base station can directly configure the target time unit offset for the terminal through RRC signaling or MAC signaling.

After the base station determines the time unit number of the specified time unit and the target time unit offset, the base station may use the sum of the two as the target time unit number.

For example, if the time unit number of the specified time unit is 24 and the target time unit offset is 4, the target time unit number is 28. Accordingly, the 28th time unit is the target time unit.

In the above embodiments, the time unit may be a subframe, a time slot, or the like.

In the embodiment of the present disclosure, after determining the target time unit, the base station may start receiving the second data block repeatedly uploaded by the terminal at the next time unit of the target time unit. For example, if the target time unit is the 28th time unit, the base station may start receiving the second data block from the 29th time unit.

In the above embodiment, after the base station successfully demodulate the first data block uploaded by the terminal, it can start receiving the second data block repeatedly uploaded by the terminal at the next time unit of the target time unit, and accurately determine the time point when the second data block is started to be received. To avoid missing data affecting terminal services and high availability.

In an embodiment, referring to FIG. 5, FIG. 5 is a flowchart of another early termination transmission method according to the embodiment shown in FIG. 3. After step 103, the method may further include:

In step 105, determine at least one candidate data block for the terminal;

In this step, the base station may directly use all the data blocks except the first data block among the data blocks that the terminal currently does not upload to the base station as the candidate data blocks. For example, if all data blocks except the first data block TB1 that the terminal does not currently upload to the base station include TB2, TB3, and TB4, the base station uses TB2, TB3, and TB4 as candidate data blocks.

Alternatively, the base station may use a candidate number of data blocks after the first data block as the candidate data block.

For example, if the candidate data is 2, the base station may use TB2 and TB3 after the first data block TB1 as candidate data blocks.

In the embodiment of the present disclosure, the base station may determine the candidate number in any of the following manners.

In a first manner, a predetermined number of data blocks is used as the candidate number.

In this manner, the base station may directly use the number of data blocks predefined in the communication protocol as the candidate number.

In a second manner, the candidate number is configured for the terminal through the first preset signaling or the second preset signaling.

The first preset signaling may be RRC signaling, and the second preset signaling may be MAC signaling. The base station can directly configure the candidate number for the terminal through RRC signaling or MAC signaling according to the channel status and its own situation.

In step 106, a second target number of times is configured for the terminal; the second target number of times is the maximum number of times the terminal repeatedly uploads the candidate data block, and the second target number of times is less than the first target number of times frequency;

In the embodiment of the present disclosure, optionally, the base station may also use any of the following methods to configure the second target number of times for the terminal.

In a first manner, a set of candidate times is configured for the terminal through a first preset signaling, and a value is specified as the second target times in the candidate offset set through the target DCI.

In this way, the base station can configure a set of candidate times for the terminal through RRC signaling, for example, the set of candidate times is {6, 16, 24, 32}, and the first target number of times is 32, then the base station can pass the target DCI In the above-mentioned candidate number set, a value smaller than the first target number is selected as the value corresponding to the second target number, for example, 24 is selected as the value corresponding to the second target number.

In a second manner, the base station configures a candidate offset set for the terminal through the first preset signaling, and selects one of the candidate offset sets as a value corresponding to the target offset through the target DCI. , And the terminal obtains the second target number of times according to the first target number of times and the target offset.

In this way, the base station can first configure a candidate offset set for the terminal through RRC signaling, such as {-4, -8, -12, -16}, and then use the target DCI for the terminal at the candidate offset. Select one from the set as the target offset, such as -8 as the target offset. The terminal may calculate the sum of the first target number of times and the target offset to obtain the second target number of times, for example, the calculated second target number of times is 32-8 = 24.

In step 107, after the terminal selects one of the candidate data blocks as the second data block, the terminal repeatedly receives the second data block uploaded according to the second target number of times.

In this step, after the base station determines the candidate data block and the second target number of times, the terminal selects one of the candidate data blocks as the second data block, and repeatedly uploads the second data block to the base station according to the second target number of times. , The base station can receive.

The maximum number of times the terminal uploads the second data block does not exceed the second target number of times.

In the above embodiment, the base station needs to determine at least one candidate data block for the terminal and configure a second target number of times for the terminal, and the second target number of times is the maximum number of times that the terminal repeatedly uploads the candidate data block. And the second target number of times is less than the first target number of times. Therefore, the base station can reduce the number of repeated uploads of the candidate data block according to the current channel condition, and improve the transmission efficiency.

In an embodiment, the target DCI indication configured by the base station includes an early termination indication field. Optionally, the base station may configure the early termination indication field in the target DCI in the following manner:

In the first coverage enhancement mode with better coverage conditions, for example, in coverage enhancement mode A, the base station may use the resource corresponding to the physical resource block specified in advance in the target DCI as the early termination indication domain, and use the early termination indication domain. The domain is configured to a first preset value.

For example, the base station may set the resources of the 5-bit physical resource blocks specified in the target DCI in advance to 1, and after receiving the target DCI, the terminal determines that the first data unit needs to be terminated in advance.

In addition, in a second coverage enhancement mode with poor coverage conditions, for example, in coverage enhancement mode B, the base station may use the resource corresponding to the modulation and coding mode domain specified in advance in the target DCI as the early termination indication domain, and The early termination indication field is configured as a second preset value.

For example, the base station may set the resources corresponding to the 4-bit modulation and coding mode domain specified in advance in the target DCI to 1, and after receiving the target DCI, the terminal determines that the first data unit needs to be terminated in advance.

In the embodiment of the present disclosure, the first preset value and the second preset value may be the same or different, which is not limited in the present disclosure.

In an embodiment, the target DCI may further include the second target number of times. Optionally, in the target DCI, a domain multiplex corresponding to the second target number of times is used to instruct the terminal to repeatedly upload the physical A domain of the number of repeated uploads of the uplink shared channel PUSCH.

In the embodiment of the present disclosure, the second target number of times may also reuse other fields in the target DCI, which is not limited in the present disclosure.

In the above embodiment, the target DCI sent by the base station may further include a second target number of times; the second target number of times is the maximum number of times the terminal repeatedly uploads the candidate data block, and the second target number of times is less than The first target number of times is described.

In step 202, if the target DCI sent by the base station is received before the total number of repeated uploads of the first data block does not reach the first target number, the upload of the first data block to the base station is terminated in advance. The first target number of times is a maximum number of repeated uploads of each data block configured by the base station for the terminal;

In step 203, after the uploading of the first data block is terminated in advance, the second data block is repeatedly uploaded to the base station; the second data block is one of the data blocks that the terminal currently does not upload to the base station. .

In the above embodiment, the terminal may repeatedly upload the first data block to the base station. If the base station determines that the first data block is successfully demodulated before the total number of times the terminal repeatedly uploads the first data block does not reach the first target number of times, Then, the base station sends the target DCI to the terminal. The terminal may stop repeatedly uploading the first data block to the base station according to the target DCI, and then repeatedly upload the second data block to the base station. Through the above process, in the case that the terminal repeatedly uploads data blocks, the base station can send the target DCI to the terminal when the current data block is successfully demodulated to terminate the terminal in advance to continue uploading the current data block, which is beneficial to saving MTC system terminals H.

For the above step 201, the terminal may repeatedly upload the first data block to the base station in the MTC system according to the related technology.

After the terminal receives the target DCI according to related technologies, if the terminal is in the first enhanced coverage mode with better current coverage conditions, for example, in the coverage enhancement mode A, the terminal can find whether the value corresponding to the early termination domain of the target DCI is the first preset. value. For example, to find whether the value corresponding to the resource of the 5-bit physical resource block specified in the DCI is 1, and if 1, the DCI is determined to be the target DCI, and the transmission of the first data block is to be terminated in advance according to the indication of the early termination instruction field.

In addition, after receiving the target DCI according to related technologies, if the terminal is in the second enhanced coverage mode with poor current coverage conditions, for example, in the coverage enhancement mode B, the terminal can find whether the value corresponding to the early termination domain of the target DCI is the second default value. For example, find whether the value corresponding to the resource corresponding to the 4-bit modulation and coding mode domain specified in advance in the DCI is 1. If it is 1, determine that the DCI is the target DCI, and the transmission of the first data needs to be terminated in advance according to the instruction of the early termination instruction field Block to base station.

For step 203, the terminal may repeatedly upload a second data block to the base station after stopping uploading the first data block to the base station; the second data block is a data block that the terminal does not currently upload to the base station. one of.

Or the terminal stopped uploading the first data block to the base station at the 20th time unit, and the target time unit number is 28. Then, the terminal may enter the sleep state at the 20th time unit until the end of the 28th time unit.

Accordingly, step 203 may be specifically:

For example, if the target time unit is the 28th time unit, the terminal may repeatedly upload the second data block to the base station at the 29th time unit.

In this step, the terminal may select one of the candidate data blocks determined in step 205 as the second data block. Alternatively, the terminal may select among the data blocks in the order of the data blocks. Further, the terminal may repeatedly upload the second data block according to the second target number of times determined in step 206.
