Abstract
The present disclosure includes systems, devices, and methods that provide a control signaling transmission method. One example method includes: determining a resource subset used to transmit control signaling, where the resource subset is a part of a resource pool used to transmit the control signaling; and performing one of the following operations: determining a transmission location of the control signaling in the resource subset and sending the control signaling at the transmission location, or performing blind control signaling detection in the resource subset.
Claims14
A method, applied to a transmit-end device in end-to-end communications, comprises:
- determining a transmission resource of a control signaling in a resource subset for transmitting control signaling, wherein the resource subset belongs to a resource pool used to transmit the control signaling and data, the control signaling and the data are frequency division multiplexed in a same subframe and are continuous in frequency domain, and a transmission resource of the data is preset to be at a frequency higher than that of the transmission resource of the control signaling in the same subframe;
- and
- sending the control signaling at the transmission resource of the control signaling, and the control signaling indicates a frequency length of the data;
- sending the data at the transmission resource of the data.
A method, applied to a receive-end device in end-to-end communications, comprises:
- determining a resource subset used to transmit control signaling based on a preset rule, wherein the resource subset belongs to a resource pool used to transmit the control signaling and data, and the preset rule comprises that the resource subset is a specified resource set;
- and
- performing blind control signaling detection in the resource subset, the control signaling indicates a frequency length of the data;
- after the control signaling is correctly received at a transmission resource of the control signaling in the resource subset, receiving the data at a transmission resource of the data;
- wherein, the control signaling and the data are frequency division multiplexed in a same subframe and are continuous in frequency domain, and the transmission resource of the data is preset to be at a frequency higher than that of the transmission resource of the control signaling in the same subframe.
A control signaling transmission device, wherein the device comprises:
- a non-transitory memory storage comprising instructions;
- and

- and
- send the control signaling at the transmission resource of the control signaling, and the control signaling indicates a frequency length of the data;
- send the data at the transmission resource of the data.
