Abstract
This application provides a method and device for generating a subframe, a method for determining a subframe and a user equipment. The method for generating a subframe includes: determining, by a first device, patterns of at least two special subframes used in a broadcast control channel modification period, where guard period GP durations of the at least two special subframes are different; and generating, by the first device, the at least two special subframes. The method enhances flexibility and improves a system resource utilization rate.

A device for generating signals on a time domain unit, the device comprising:
- a processor configured to:
- determine patterns of at least two time domain units used in a period, wherein guard period (GP) durations between an uplink duration and a downlink duration of the at least two time domain units are different,
- generate signals on the at least two time domain units according to the determined patterns, and
- generate control information used to indicate the at least two time domain units, wherein the control information includes special subframe effective time;
- and
- a transceiver configured to:
- transmit the control information to a second device;
- and
- use a GP of a first time domain unit in the at least two time domain units to receive a signal, and use a downlink pilot time slot in the first time domain unit to transmit the signal;
- wherein after using the GP of the first time domain unit in the at least two time domain units to receive the signal, the processor is further configured to use the received signal to perform synchronous tracking and/or energy detection;
- and
- wherein the transceiver is further configured to:
- use the GP of the first time domain unit to receive a synchronization signal;
- and
- transmit the synchronization signal to a lower-level device using a second time domain unit in the at least two time domain units, wherein the GP duration of the first time domain unit is larger than a GP duration of the second time domain unit.
