- the active time can also be called the active period, the active time, etc., and the terminal device is in the active state during the active time.
- the inactive time can also be called the inactive time, the inactive period, etc., and the terminal device is in the inactive state during the inactive time.
- the terminal device When the terminal device is configured with the DRX mechanism, the terminal device first enters the activation time/On Duration at the arrival of each DRX cycle, and starts the DRX duration timer (drx-onDurationTimer). After the DRX duration timer times out, the terminal device will enter the inactivity time; if a PDCCH scheduling data transmission is detected during the On Duration period, the terminal device starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the DRX inactivity timer is running, the terminal device is in the activation time.

- the UE During the operation of the timer, the UE enters the Short DRX cycle state, that is, the on Duration is determined according to the Short DRX cycle; when the drx-ShortCycleTimer ends, the UE enters the Long DRX cycle state, that is, the onDuration is determined according to the Long DRX cycle.
- the terminal device can re-enter the Short DRX Cycle after each drx-InactivityTimer ends; when no data arrives for a period of time, it can switch to the Long DRX cycle.
- the base station can force the device to enter the Short DRX cycle through the DRX Command MAC CE, or force the device to enter the Long DRX cycle through the Long DRX Command MAC CE.
- the network device can be enabled not to send data transmission for a period of time, or the network device can be enabled not to send all channels or part of the channels for a period of time.

- the network device needs to configure a PRACH for the terminal device to access the system.
- the movement of the terminal device makes the distance between the terminal device and the network device uncertain, so if the terminal device needs to send a message to the base station, it must maintain and manage the uplink synchronization in real time.
- the purpose of PRACH is to achieve uplink synchronization, establish the uplink synchronization relationship between the terminal device and the network device, and request the network device to allocate dedicated resources to the terminal device, so that the terminal device can access the network device normally for service transmission.
- the terminal device will first send message 1 (Msg1), that is, PRACH.
- Msg1 message 1
- the terminal device After sending PRACH, the terminal device will receive message 2 (Msg2) and send message 3 (Msg3). If the terminal device performs contention-based random access, the terminal device will also receive message 4 (Msg4). Therefore, after the terminal device sends PRACH, the network device can know that the terminal device is performing a random access process, and there is a subsequent transmission demand for Msg2, Msg3 and Msg4.
- the terminal device can send an uplink scheduling request (Schedule Request, SR) to request the network device to schedule uplink transmission, such as requesting the network device to schedule PUSCH.
