Description

Method and device for determining transmission opportunity, storage medium and electronic device
Technical Field
The present invention relates to the field of communications, and in particular, to a method and apparatus for determining a transmission opportunity, a storage medium, and an electronic apparatus.
Background
The standard formulation work of the first stage of the fifth generation mobile communication technology (5G,the 5th Generation mobile communication technology) is completed. From the trend of standard formulation and technology development, 5G systems are dedicated to research on technical indexes such as higher rate (Gbps), huge amount of links (1M/Km 2), ultra-low time delay (1 ms), higher reliability, hundred times of energy efficiency improvement and the like to support new demand changes.
In order to support the characteristics of ultra-high reliability and ultra-low delay transmission, the transmission of the low-delay and high-reliability service in a shorter transmission time is completed, and the uplink and the downlink are required to be enhanced. In particular, in uplink, after the terminal sends the scheduling request, the terminal can receive the uplink authorization information of the base station at a certain interval, and then can send corresponding uplink data at a certain interval. Therefore, in order to meet the requirement of ultra-low delay transmission of an uplink, an uplink unlicensed transmission mode (PUSCH without UL grant) is proposed in the 5G stage, and in order to meet the characteristic of high reliability, a method for repeatedly transmitting the same uplink data for a plurality of times is also proposed. In the current Uplink grant-free multiple repetition transmission technology, when the time domain position of the repeated transmission configuration of the Uplink data for multiple times is semi-static by the higher layer signaling (Radio Resource Control, RRC), and the time slot format indication field (Slot format indicator, SFI) of the downlink control information format 2_0 (Downlink Control Information, DCI format 2_0) is already specified by the protocol, and indicates that the transmission direction of the flexible symbols can only be Uplink, the repeated Uplink data can be sent, and if the SFI indicates that the transmission direction of the flexible symbols is also flexible, the symbols are reserved and no information can be transmitted. The SFI is used to indicate the transmission direction on the time domain symbol, which is downlink or uplink or flexible.
Therefore, according to the current protocol, when the uplink transmission direction of the repeated transmission collides with the transmission direction indicated by the DCI format 2_0, all the uplink data of the repeated times are discarded. However, the uplink data of the uplink unlicensed repeated transmission is often of a service type with high delay requirement and extremely high reliability requirement, and if all the uplink data are lost and not transmitted, the service performance is greatly damaged.
Aiming at the problem that in the related art, when the resource allocation information and the time domain format indication information conflict, the uplink data cannot be transmitted in a general mode, so that all the repeatedly transmitted uplink data are lost easily, no effective solution has been proposed in the related art.

From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment. Based on such understanding, the technical solution of the present invention may be embodied essentially or in a part contributing to the prior art in the form of a software product stored in a storage medium (e.g. ROM/RAM, magnetic disk, optical disk) comprising instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the method according to the embodiments of the present invention.
The following description of the specific embodiments will provide a more clear description of the method for determining a transmission opportunity according to the embodiment of the present invention:
example 1
When the configured redundancy version sequence= {0, 0}, and the number of repeated transmission opportunities k=8, the terminal detects that the SFI field of DCI format2_0 indicates that the transmission direction is flexible on the first transmission opportunity, but detects that the SFI field of DCI format2_0 indicates that the transmission direction is uplink on the fifth transmission opportunity; and DCI format2_0 is not detected any more until the eighth transmission opportunity.
In the above case, as shown in fig. 2, the uplink data may be further repeatedly transmitted 4 times, while the data on the first to fourth transmission opportunities are not transmitted.
Example 2
When the configured redundancy version sequence= {0, 0}, the number of repeated transmission opportunities k=8, the terminal detects that the SFI field of DCI format2_0 on the first transmission opportunity indicates that the transmission direction is flexible, but detects that the DCI format2_0 only on the eighth transmission opportunity, and the SFI field indicates that the transmission direction is uplink.
In the above case, as shown in fig. 3, uplink data on 8 transmission opportunities cannot be transmitted according to the protocol specification.
Example 3
When the configured redundancy version sequence= {0, 0}, the number of repeated transmission opportunities k=8, the terminal detects that the SFI field of DCI format2_0 on the first transmission opportunity indicates that the transmission direction is flexible, but detects that the DCI format2_0 only on the seventh transmission opportunity, and the SFI field indicates that the transmission direction is uplink. And DCI format2_0 is not detected any more until the eighth transmission opportunity.
In the above case, as shown in fig. 4, the uplink data may be further repeated 2 times without transmitting the data on the first to sixth transmission opportunities.
Example 4
When the configured redundancy version sequence= {0, 0}, the number of repeated transmission opportunities k=8, the terminal detects DCI format2_0 on the first transmission opportunity, the sfi field indicates that the transmission direction is uplink, but detects dcifermat2_0 on the fifth transmission opportunity, and the sfi field indicates that the transmission direction is flexible. And DCI format2_0 is not detected any more until the eighth transmission opportunity.
In the above case, as shown in fig. 5, the uplink data may be further repeatedly transmitted 4 times, while the data on the fifth to eighth transmission opportunities are not transmitted.
Example 5

And DCI format2_0 is not detected any more until the eighth transmission opportunity.
In the above case, as shown in fig. 7, the uplink data may be further repeated 2 times without transmitting the data on the first to sixth transmission opportunities. It should be further noted that, although the sixth transmission opportunity is also the uplink transmission direction, the redundancy version on the sixth transmission opportunity is 3, and therefore cannot be used as the starting position of the first transmission, and only the transmission of uplink data can be performed on the seventh transmission opportunity with the redundancy version of 0.
Example 7
When the configured redundancy version sequence= {0,3,0,3}, the number of repeated transmission opportunities k=8, the terminal detects DCI format2_0 on the first transmission opportunity, the sfi field indicates that the transmission direction is uplink, but detects dcife format2_0 on the sixth transmission opportunity, and the sfi field indicates that the transmission direction is flexible.

In the above case, as shown in fig. 9, data on eight transmission opportunities cannot be transmitted. It should be further noted that, in the case of redundancy version = {0,2,3,1}, the protocol specifies that transmission can only be started from the first transmission opportunity.
Example 9
When the configured redundancy version sequence= {0,2,3,1}, the number of repeated transmission opportunities k=8, the terminal detects DCI format2_0 on the first transmission opportunity, the sfi field indicates that the transmission direction is uplink, but detects DCI format2_0 on the fifth transmission opportunity, and the sfi field indicates that the transmission direction is flexible.
In the above case, as shown in fig. 10, the uplink data may be further repeatedly transmitted 4 times, while the data on the fifth to eighth transmission opportunities are not transmitted.
