- the former corresponds to the base station successfully receiving the PUSCH by using partial repetition (repetition), and the latter corresponds to the base station successfully receiving the PUSCH of all HARQ processes.
- the signal transmission RTT between terminal equipment and network equipment is very short.
- the time for the base station to respond to UL HARQ ACK feedback mainly considers the decoding time after the network equipment receives PUSCH and the time allocated for transmitting UL HARQ ACK feedback resources. , usually a few milliseconds, and greater than the RTT of the signal transmission between the terminal device and the network device.
- the terminal device in order to support UL HARQ ACK feedback, the terminal device will enter the DRX activation period during the repeated transmission of PUSCH. At the same time, after the terminal device completes the repeated transmission of PUSCH, it will immediately start the drx- ULRetransmissionTimer. In this way, the terminal device will continuously monitor the PDCCH used to indicate the UL HARQ ACK feedback during sending the PUSCH and for a period of time after completing the PUSCH transmission.
- the signal propagation delay between terminal equipment and network equipment in NTN is greatly increased, and its RTT is much greater than the terminal equipment processing time considered in the existing terrestrial network equipment standards, which also gives UL HARQ ACK
- the feedback mechanism poses new problems. For example, it takes a long time (at least one RTT) from when the terminal device sends part of the repetition of PUSCH to when the network device successfully receives this part of repetition and sends the UL HARQ ACK feedback response, and then until the terminal device receives the UL HARQ ACK feedback. , because the RTT time is too long, if the terminal device still uses the existing DRX mechanism, it will cause unnecessary PDCCH monitoring of the terminal device, which is not conducive to power saving of the terminal device.
- an embodiment of the present invention provides a method for determining the DRX activation period.
- the terminal device can determine the discontinuous reception DRX activation period according to the transmission duration of the physical uplink shared control channel PUSCH bundled transmission and the first round trip time RTT.
- PDCCH monitoring is performed. Since the transmission duration of PUSCH bundled transmission and the first round-trip time RTT are considered when determining the DRX activation period of discontinuous reception, even if the RTT time is longer In the scenario, unnecessary PDCCH monitoring will not be caused, so that the power of the terminal device can be saved.
