When, transmission unit is specifically used for: sending down control channel configuration information to terminal housing estate by broadcast message, makes terminal housing estate
Interior all terminals receive identical down control channel configuration information, the downlink control for all terminals to low delay business
Channel processed carries out monitoring and blind examination；Or when mode sends to send the mode of RRC information, transmission unit is specifically used for: logical
It crosses RRC information and sends down control channel configuration information to terminal, terminal is made to receive the downlink control different from other terminals
Channel configuration information, so that down control channel of the terminal to low delay business carries out monitoring and blind examination.
In this embodiment, the down control channel that various ways Notification URL LC terminal can be used in base station is configured,
It include: broadcast message and RRC information.By broadcast message, the broadcast downstream control channel into cell is configured for base station, in such feelings
Under condition, the URLLC terminal that can receive the broadcast message in a cell has identical down control channel to configure；Base station is logical
When crossing the configuration of RRC information Notification URL LC user equipment downlink control channel, since RRC information is UE-specific, therefore each URLLC
Terminal can have different or identical down control channel configuration.
In one embodiment of the invention, it is preferable that transmission unit is also used to send by physical layer signaling to terminal
The change message of down control channel configuration information.
In this embodiment, broadcast message and the configuration of RRC information Notification URL LC user equipment downlink control channel are being used
Afterwards, the change that base station can also use physical layer signaling Notification URL LC user equipment downlink control channel to configure.Compared to directly use
It broadcasts the message with RRC information and leads to the method for the change of down control channel configuration, base can be effectively reduced using physical layer signaling
Time delay needed for station notifies the change.
In one embodiment of the invention, it is preferable that down control channel configuration information includes but is not limited to next
Kind or combinations thereof: the symbol numbers of RB mark, control channel occupancy that control channel sending cycle, control channel occupy control
The time domain of channel deviates；Wherein, control channel sending cycle is that down control channel the symbol numbers being spaced occurs every time；Control
The RB of channel occupancy is identified as the RB mark that down control channel occupies on frequency domain；Under the symbol numbers that control channel occupies are
The symbol numbers that row control channel occupies every time；The time domain offset of control channel starts to send out to send in interval in each eMBB
Send down control channel corresponding symbol.
In this embodiment, base station sends URLLC user equipment downlink control channel configuration information, and URLLC terminal receives under this
Row control channel configuration information.URLLC down control channel configuration information indicates under all possible carrying URLLC terminal
The physical resource of row control information.URLLC down control channel configuration information may include control channel sending cycle, each secondary control
RB number of channel occupancy processed, the symbol numbers of each secondary control channel occupancy, the offset of the time domain of control channel etc..From URLLC industry
For the angle of business demand, the sending cycle of control channel should be as short as possible, in this way, whenever there is the arrival of URLLC business burst
When, so that it may it sends as early as possible.But if the sending cycle of control channel is too short, for example, 1 symbol, then terminal needs every
A symbol will do DCI blind detection, this will increase the power consumption of terminal.Therefore, base station can in conjunction with actual business demand and
Terminal situation configures suitable downlink control channel information for terminal.
