Background
Currently, development work of a 5 th generation mobile communication system (5G) is actively underway. According to the future application requirements, the 5G system needs to support a variety of service scenarios, including EMBB (Enhanced Mobile Broadband), URLLC (Ultra-reliable and Low Latency Communications), and MMTC (Massive Machine Type of Communication). In the process of standard formulation, it is proposed that an enhancement is needed in terms of terminal power saving, in 3GPP (3rd Generation Partnership Project) R14 standard, a major research is made on terminal power saving in RRC-connected state, in R16 standard, a further research is made on power saving in RRC-connected state, and of course, how to save power in RRC _ IDLE state/RRC _ INACTIVE state.
Communication in the RRC-connected state consumes more power than in the RRC-IDLE or RRC _ INACTIVE state, and a terminal in a power saving state periodically monitors a PDCCH (Physical Downlink control channel) in the RRC-connected mode, and if data is transmitted, the terminal communicates according to a Downlink control signaling of a gNB (base station), but the power saving requirement in the RRC-connected state is higher, so that there is a technical proposal to determine whether a UE (User Equipment) needs to wake up to monitor the PDCCH, and before that, a wake-up message needs to be received, if a wake-up message is received, the UE wakes up to monitor the PDCCH, and if a wake-up message is not received, the UE continues to sleep. However, this technique merely proposes such a mechanism, and no provision is made for the content of the wake-up message and the type of the wake-up message.

The terminal receives the wake-up message sent by the base station, acquires the wake-up identifier when the wake-up message is the multicast/broadcast wake-up message, enters the wake-up state from the dormant state according to the indication of the wake-up identifier and starts to monitor the downlink control channel. When the wake-up message is a unicast wake-up message, the terminal enters a wake-up state from a dormant state when receiving the unicast wake-up message and starts monitoring a downlink control channel, and if the unicast wake-up message is not received, the terminal continues to sleep. By adopting the technical scheme of the invention, the type of the wake-up message is regulated, so that the mechanism that the terminal receives the wake-up message to wake up and monitors the downlink control channel can be implemented more clearly and accurately, the terminal can accurately monitor the downlink control channel, and the aim of saving power of the terminal is fulfilled.
The wake-up message comprises a multicast wake-up message and/or a unicast wake-up message, or a broadcast wake-up message and/or a unicast wake-up message. It should be noted that if the terminal receives the multicast/broadcast wakeup message, it negotiates with the gNB that it is assigned to a specific group before receiving it, and for the terminal that receives the multicast wakeup message, it may not need to define to receive the unicast wakeup message, but if the terminal leaves a certain group for which the gNB is specifically assigned, the terminal may negotiate with the gNB that it can receive the unicast wakeup message.
In a specific embodiment, the terminal may be a network device such as a smart phone, a tablet computer, and a notebook computer.
Fig. 2 is a flowchart illustrating a method for monitoring a downlink control channel according to another embodiment of the present invention. Wherein, the method comprises the following steps:
step 202, receiving a wake-up message sent by a base station, wherein the wake-up message comprises a multicast/broadcast wake-up message and/or a unicast wake-up message;
step 204, when the wake-up message is a multicast/broadcast wake-up message, acquiring a wake-up identifier in the multicast/broadcast wake-up message, when the wake-up identifier indicates that the terminal needs to be woken up, entering a wake-up state from a sleep state, and starting to monitor a downlink control channel; when the awakening message is a unicast awakening message, entering an awakening state from a dormant state according to the unicast awakening message, and starting to monitor a downlink control channel;
step 206, when the wake-up message is a multicast/broadcast wake-up message, acquiring first time information in the multicast/broadcast wake-up message; when the awakening identifier indicates that the terminal needs to be awakened, analyzing the first time information to obtain first receiving time, and receiving terminal public information at the first receiving time in a downlink control channel; when the wake-up identifier indicates that the terminal does not need to be woken up, not analyzing the first time information; and when the awakening message is the unicast awakening message, acquiring second time information in the unicast awakening message, acquiring second receiving time according to the second time information, and entering an awakening state from a dormant state and receiving terminal specific information in a downlink control channel at the second receiving time.
In this embodiment, the multicast/broadcast wake-up message further includes time information (corresponding to the terminal side is the first time information) of the terminal public information sent by the base station, when the wake-up identifier indicates that a certain terminal needs to be woken up, the terminal analyzes the time information to obtain the first receiving time, and receives the terminal public information at the first receiving time, so as to ensure that the terminal successfully receives the terminal public information. If the awakening identifier corresponding to a certain terminal identifies that the terminal does not need to awaken, the terminal does not need to analyze the first time information and does not need to awaken to monitor the downlink control channel, so that power consumption of the terminal is avoided. The wake-up identifier may be a unit location, a unique identification, assigned by the base station to the terminal in the multicast message frame, and may be the same in different groups.
The unicast wakeup message includes the sending time (corresponding to the second receiving time at the terminal side) of the downlink control channel for the terminal specific information, and the terminal can continue to sleep before the second receiving time is reached, so that power consumption of the terminal is avoided. And when the terminal receives the terminal specific information, the terminal is ensured to successfully receive the terminal specific information.
Further, for the reception frequency resource of each time period, no limitation is made in the present invention.
Preferably, step 202, receiving the wake-up message sent by the base station specifically includes: when the wake-up message is a multicast/broadcast wake-up message, receiving a radio resource control signaling sent by a base station, and acquiring the multicast/broadcast wake-up message from the radio resource control signaling; and when the awakening message is the unicast awakening message, receiving the time sequence of the unicast awakening message sent by the base station, and receiving the unicast awakening message on the time sequence.
In this embodiment, the multicast/broadcast wakeup message is a system message, and may be configured through RRC (Radio resource control signaling). Before entering the power saving mode, the terminal negotiates with the base station about the sending time sequence of the unicast wake-up message, that is, the base station divides a period of time sequence as the time length for sending the unicast wake-up message, and the terminal can receive the unicast wake-up message on the time sequence. The time frequency resource for sending the awakening message is regulated, so that the mechanism for receiving the awakening message by the terminal to awaken and monitor the downlink control channel can be implemented more clearly and accurately.
Preferably, in step 204, acquiring the wake-up identifier in the multicast/broadcast wake-up message specifically includes: and receiving identifier position information sent by the base station, and acquiring the awakening identifier at a corresponding position in the multicast/broadcast awakening message.
In this embodiment, before the terminal goes to sleep, the location of the wake-up identifier needs to be negotiated with the base station. Specifically, the identifier position information sent by the base station is received, and the position of the wake-up identifier in the multicast/broadcast wake-up message is determined according to the identifier position information, so that the wake-up identifier can be quickly and accurately acquired in the multicast/broadcast wake-up message, and the mobile terminal can quickly enter the wake-up state.
Preferably, the timing of the multicast/broadcast wake-up message precedes the timing of the unicast wake-up message; there are multiple unicast wake-up messages after the multicast/broadcast wake-up message.
In this embodiment, since the multicast/broadcast wake-up message involves multiple terminals, its timing should precede the unicast wake-up message, and there may be multiple unicast wake-up messages following the multicast/broadcast wake-up message.
Preferably, the first reception time is before the second reception time.
In this embodiment, the multicast/broadcast may occur before the unicast, and the first receiving time of the terminal common information is before the second receiving time of the terminal specific information, thereby ensuring that the terminal saves more power.
