PDCCH MONITORING METHOD AND DRX UPLINK RETRANSMISSION TIMER CONTROL METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18450390 titled 'PDCCH MONITORING METHOD AND DRX UPLINK RETRANSMISSION TIMER CONTROL METHOD
Simplified Explanation
- The patent application is related to communications technology and specifically focuses on PDCCH monitoring and DRX uplink retransmission timer control methods. - The PDCCH monitoring method allows a terminal device to start monitoring a PDCCH (Physical Downlink Control Channel) from a specific moment in a bundle corresponding to a PUSCH (Physical Uplink Shared Channel). - The value of N, which determines the moment of PDCCH monitoring, can be adjusted based on factors like the Round Trip Time (RTT) between the terminal device and the network device. - This method helps to avoid unnecessary PDCCH monitoring by the terminal device, leading to power savings. - The DRX (Discontinuous Reception) uplink retransmission timer control method ensures that the terminal device starts the timer at an appropriate time, neither too early nor too late. - By doing so, the method ensures that the terminal device does not miss receiving uplink HARQ-ACK (Hybrid Automatic Repeat Request-ACKnowledgement) feedback sent by the network device. - This approach facilitates power savings for the terminal device.
Original Abstract Submitted
The present application relates to the technical field of communications, and discloses a PDCCH monitoring method and a DRX uplink retransmission timer control method. For the PDCCH monitoring method, a terminal device begins to monitor a PDCCH from a moment corresponding to the Nth or (N+1)th duplicate transmission in a bundle corresponding to a PUSCH, and the value of N can be set according to values such as RTT between the terminal device and a network device, thereby avoid unnecessary PDCCH monitoring by the terminal device, facilitating power saving of a terminal. For the DRX uplink retransmission timer control method, the terminal device starts a DRX uplink retransmission timer at an appropriate time so as not to start same too early or too late, thereby ensuring that the terminal device does not miss receiving uplink HARQ-ACK feedback sent by the network device, facilitating power saving of a terminal.
