Description
Technical Field
The present invention relates to the field of communication technologies, and in particular, to a wireless communication method using a wake-up signal for a base station or a terminal and a wireless communication apparatus using a wake-up signal for a base station or a terminal.
Background
In 3GPP (3rd Generation Partnership project, third Generation Partnership project), it is proposed that a terminal in an RRC-Connected (Radio Resource Control-Connected) state uses DRX (Discontinuous Reception), that is, periodically wakes up to perform downlink Control channel blind detection lasting for several milliseconds, as shown in fig. 1, if a downlink Control channel addressed to the terminal is not detected, a closed state may be entered after the wake-up is completed, and if a downlink Control channel addressed to the terminal is detected, the awake state is maintained until the data transmission and Reception are completed. In this way, the downlink control channel is blind detected in the awake state, but there is a case where there is no data transmission in the awake state, and the blind detection in this case wastes terminal energy.
To solve this problem, a scheme of sending a Wake Up Signal (WUS) is proposed, that is, a base station sends a Wake Up Signal to a terminal before the Wake Up state starts, and as shown in fig. 2, when the Wake Up Signal arrives, the terminal needs to be turned on briefly to receive the Wake Up Signal. If the wake-up signal indicates that the terminal is turned on, the terminal will be turned on when the wake-up state comes, and if the wake-up signal indicates that the terminal is turned off, the terminal will be kept in the off state and will not be turned on even if the wake-up state comes. However, in the prior art, it is not determined what time-frequency resource the wake-up signal should be sent, and therefore, finding out a method for sending the wake-up signal has become a technical problem to be solved urgently.
