Description

Method and device for terminating repeated transmission, storage medium and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for terminating repeated transmission, and a storage medium/device.

Background

In R18 (Release 18), in order to enhance the coverage of the PRACH (Physical Random Access Channel, random access channel) signal, the UE (User Equipment) may perform PRACH retransmission.

In the related art, the number of repetitions is preset, and when the repetition transmission is performed, the number of repetitions of the repetition transmission is counted, and the transmission is stopped until the number of repetitions reaches the preset number of repetitions.

However, in the related art, when the UE performs the retransmission, the UE may need to terminate the retransmission in advance. For example, when the channel quality is good enough, the coverage requirement can be met with a small number of repetitions, without reaching the preset number of repetitions, at which time the repetition can be terminated in advance; or when the repeated transmission is not completed, the UE determines that the base station does not receive the signal sent by the successful UE, and at the moment, the repeated transmission needs to be terminated in advance and the retransmission of the signal is triggered. Therefore, how to terminate the repeated transmission of the UE in advance is a problem to be solved.

The terminal device may communicate with one or more core networks via a RAN (Radio Access Network ), and the UE may be an internet of things terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an internet of things terminal, e.g., a fixed, portable, pocket, hand-held, computer-built-in, or vehicle-mounted device.

Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

Wherein, in one embodiment of the present disclosure, the signal may be a PRACH signal.

And, in one embodiment of the present disclosure, the UE is a UE supporting early termination of repeated transmissions.

Further, in one embodiment of the present disclosure, the UE may determine whether the UE satisfies the early termination condition based on an instruction or a response message transmitted by the base station. And, in another embodiment of the present disclosure, the UE may autonomously determine whether it satisfies the early termination condition. Wherein the details of this section will be described in detail in the following examples.

In summary, in the method for terminating the retransmission provided in the embodiments of the present disclosure, the UE may terminate the retransmission of the signal in advance in response to the UE satisfying the early termination condition. It can be seen that the embodiments of the present disclosure provide a method for terminating repeated transmission of a signal in advance, so that UE avoids unnecessary repeated transmission, thereby shortening transmission delay, improving resource utilization, and saving power consumption.

Fig. 2 is a flowchart of another method for terminating a retransmission provided in an embodiment of the present disclosure, which is applied to a UE, as shown in fig. 2, and the method for terminating a retransmission may include the following steps:

Step 201, in response to the UE receiving an early termination instruction sent by the base station, repeat transmission of an early termination signal (i.e. PRACH signal).

In one embodiment of the present disclosure, when the base station determines that the early termination condition is satisfied, an early termination instruction is sent to the UE to instruct the UE to repeat transmission of the early termination signal.

Specifically, in one embodiment of the present disclosure, a method for determining that an early termination condition is satisfied by a base station may include: before the UE repeatedly transmits the number of times of repetition (i.e. the number of times of repeatedly transmitting the UE to be completed, which is preset), if the base station has correctly received and demodulated the PRACH signal sent by the UE, it is considered that the PRACH signal has been successfully transmitted before the repeatedly transmitting is not completed, so that the repeated transmission of the PRACH signal is not required to be performed later, at this time, the base station may send an early termination instruction to the UE to instruct the UE to terminate the repeated transmission of the PRACH signal in advance.

And, in another embodiment of the present disclosure, a method of a base station determining that an early termination condition is satisfied may include: when the base station determines that the PRACH receiving quality meets the preset condition, the current channel quality is considered to be good enough, the coverage requirement can be met by the smaller repetition times without reaching the preset repetition transmission times, and at the moment, an early termination instruction can be sent to the UE to instruct the UE to terminate the repeated transmission of the signal in advance.

Wherein, in one embodiment of the present disclosure, the preset condition may include at least one of:

In one embodiment of the present disclosure, the first, second, and third thresholds may be the same. In another embodiment of the present disclosure, the first threshold, the second threshold, and the third threshold may be different from each other.

It should be noted that, in one embodiment of the present disclosure, the random access response message is: after the base station successfully receives and demodulates the PRACH signal, the base station feeds back the random access response message to the UE based on the PRACH signal.

Based on this, in one embodiment of the present disclosure, before the repetition transmission does not reach the repetition number, if the UE receives the random access response message sent by the base station, the UE may determine: before the retransmission is not completed, the PRACH signal is successfully transmitted, that is, the repeated transmission of the PRACH signal is not needed later, so that the UE can terminate the repeated transmission of the signal in advance.

And, in one embodiment of the present disclosure, the random access response message may include any one of the following:

In one embodiment of the present disclosure, after the UE transmits the PRACH signal to the base station, if the UE does not receive the random access response message in the RA response window, the UE considers that the base station does not successfully receive the signal transmitted by the UE. At this time, the UE may autonomously determine to terminate the repeated transmission of the signal in advance and trigger retransmission of the signal to reconnect for random access.
