Definitions
- the present disclosure relates to the field of communication technologies, and in particular to a PDCCH monitoring method and terminal.
- the base station In each Discontinuous Reception (DRX) cycle of the terminal UE in the idle state (idle state) or the radio resource control connected state (RRC connected state), the base station first transmits a wake-up signal to the UE before the UE is DRX. Wake up at the corresponding time to detect the wake-up signal. If the UE detects the wake-up signal, the UE will monitor the PDCCH during the DRX activation period (onduration); otherwise, the UE will not monitor the Physical Downlink Control Channel (PDCCH) during the DRX activation period, that is, skip After this DRX, continue to sleep.
- PDCH Physical Downlink Control Channel
- the network device when the UE needs to be awakened, the network device sends the PDCCH of the wake-up signal. If the UE does not need to monitor in the next DRX, the network may not send any PDCCH, thereby reducing the overhead of the network device. In this case, if the UE does not successfully receive the wake-up signal, the UE will miss the subsequent DRX monitoring, which will cause a larger data transmission delay. Then you need to consider enhancing the PDCCH transmission and UE monitoring to ensure wake-up Signal transmission performance.
