Abstract
A method and device of transmitting a downlink control channel, a method and device of detecting and receiving a downlink control channel are provided. The method includes: determining a blind detection period parameter of the downlink control channel; and transmitting the downlink control channel based the blind detection period parameter of the downlink control channel.
Claims26
A method of transmitting a downlink control channel applied for a base station, comprising:
- determining a blind detection period parameter of the downlink control channel;
- and
- transmitting the downlink control channel based on the blind detection period parameter of the downlink control channel,
- wherein the blind detection period parameter of the downlink control channel at least comprises:
- an offset value and/or a period value, wherein the offset value indicates an offset of a time domain resource for a user equipment (UE) to detect and receive the downlink control channel within a predetermined time domain range, the period value indicates a period for the UE to detect and receive the downlink control channel, a unit of the offset value and the period value is the same as the time domain resource,
- wherein the transmitting the downlink control channel based the blind detection period parameter of the downlink control channel comprises:
- determining a time domain resource for transmitting the downlink control channel based on the offset value and/or the period value;
- transmitting the downlink control channel on the time domain resource,
- wherein the determining a time domain resource for transmitting the downlink control channel based on the offset value and the period value comprises:
- determining the time domain source for transmitting downlink control channel by using a formula (W×nf×2k+ns−Toffset)mod Tperiod=0;
- wherein w is a predetermined time domain range,
- nf is a serial number of the predetermined time domain range;
- k is a quantity of time domain resources corresponding to different SCSs within a predetermined time unit,
- ns is a serial number of the time domain resource within the predetermined time domain rang,
- Toffset is the offset value, and
- Tperiod is the period value.
