Embodiment 1

[0194] The behavior on the base station side is as follows:

[0195] (1) The base station sends configuration information of uplink scheduling-free transmission to the UE.

[0196] For Type 2 uplink scheduling-free transmission, the base station also needs to send activation DCI.

[0197] (2) The base station receives the DMRS and the PUSCH in the configured uplink scheduling-free transmission opportunities.

[0198] (3) The base station will perform the following operations:

[0199] After receiving the DMRS, determine whether the DMRS exists, if the DMRS does not exist, the base station does not send NACK information;

[0200] If DMRS exists, the base station continues to perform PUSCH detection. If the PUSCH detection is correct, the base station does not send NACK information; if the PUSCH detection is incorrect, the base station sends NACK information before a given clock, and the NACK information can be retransmitted by the base station scheduling the PUSCH PDCCH impl...

Embodiment 2

[0209] The behavior on the base station side is as follows:

[0210] (1) The base station sends configuration information of uplink scheduling-free transmission to the UE.

[0211] For Type 2 uplink scheduling-free transmission, the base station also needs to send activation DCI.

[0212] (2) The base station receives a predetermined missing detection test sequence in the configured uplink scheduling-free transmission opportunity.

[0213] (3) The base station will perform the following operations:

[0214] After the predetermined missed detection test sequence is received, it is judged whether the predetermined missed detection test sequence exists. If it does not exist, the base station does not send the missing detection test instruction information; if the predetermined missing detection test sequence exists, the base station sends the missing detection test instruction information. .

[0215] The behavior on the terminal side is as follows:

[0216] (1) The terminal r...

Abstract

The invention provides a method for determining a missed detection, a terminal and a network device, and solves the problem that the existing method for determining a missing detection needs to consume more downlink control signaling resources. The method for determining the missed detection of the present invention includes: sending the target sequence to the network device in an uplink scheduling-free transmission opportunity; within a preset time period after sending the target sequence, if the missed detection indication information sent by the network device is received, then It is determined that no missed detection occurs in the network device, otherwise, it is determined that the missed detection occurs in the network device. In the embodiment of the present invention, it is possible to determine whether a missed detection occurs through the detection of the target sequence and the feedback of the missing detection indication information, and consume less downlink control resources.

Description

technical field [0001] The invention relates to the technical field of communication applications, in particular to a method for determining a missed detection, a terminal and a network device. Background technique [0002] With the development and changes of mobile communication service requirements, many organizations such as 3GPP have begun to study new wireless communication systems (ie, 5G NR, 5Generation New RAT) for future mobile communication systems. In the 5G NR system, an important requirement is low-latency, high-reliability communication, and transmission schemes such as low-latency high-reliability (URLLC) have emerged. Simple low-latency requirements or purely high-reliability requirements are relatively easy to achieve, but it is difficult to meet low-latency requirements and high-reliability requirements at the same time, usually at the cost of high complexity. [0003] For URLLC services, in the NR standard, the uplink scheduling-free scheme will be suppor...
