Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for terminating uplink continuous repeat transmission, a base station, and a user equipment.
Background
For URLLC (Ultra Reliable Low Latency Communication) service in 5G, 3GPP (3rd Generation Partnership Project) has been discussed to agree that URLLC users support two types of uplink transmissions based on scheduling (with grant) and non-scheduling (with grant), and for both types, a total of K times of repeated transmissions including initial transmissions to the same TB (Transport Block) are supported.
The 3GPP also discusses the termination condition when URLLC makes K transmissions and concludes that: the user repeatedly transmits the same TB until uplink scheduling (UL grant) for the TB is successfully received or the number of transmissions reaches K times. The 3GPP also discusses what possible feedback modes are available if uplink scheduling-free transmission supports HARQ (Hybrid Automatic Repeat reQuest) feedback, and agrees to further study the following three modes:
1. based on the uplink scheduling implicit indication of the new TB, HARQ feedback of the current transmission TB is ACK; 2. performing HARQ feedback to a group of users performing uplink scheduling-free transmission through group-common downlink control information (group-common DCI), where the feedback content may be only ACK, or ACK and NACK; 3. and defining a timer, and when the timing is finished, if the user does not receive NACK after the K times of repeated transmission, the user considers that the HARQ feedback content of the current TB is ACK, or if the user does not receive ACK, the user considers that the HARQ feedback content of the current TB is NACK. And further research is carried out to apply the three possible HARQ feedback modes to the K repeated transmissions. When the user performs K times of repeated transmission on the same TB, if the received HARQ feedback is ACK, the base station is considered to have successfully received the TB, and the user terminates the next repeated transmission, thereby saving transmission resources, so that the HARQ feedback ACK is another termination condition for the K times of transmission.
The 5G NR (New Radio, New air interface) introduces a CORESET (Control Resource Set), and includes two Resource types, UE-specific CORESET and common CORESET, which are respectively used for transmitting UE-specific DCI and common DCI. The uplink scheduling is exclusive to the user, so that the user monitors whether the base station transmits uplink scheduling information for the user according to a monitoring period configured by Radio Resource Control (RRC) on the UE-specific CORESET; the group common DCI in HARQ feedback mode 2 is common to the group users, so that the group users monitor all feedback information transmitted by the base station to the group users in uplink according to the monitoring period configured by the RRC on the common core set, and confirm the content of the feedback information transmitted by the corresponding user.
For an uplink K-time continuous repeated transmission mode with various termination conditions, no scheme is provided for how a monitoring period with various termination conditions is configured, and a user cannot use the various termination conditions to terminate subsequent repeated transmission in time, so that user resource waste is caused.
