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.

First claim

What is claimed is:

1. 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.

2. The device according to claim 1 , wherein the control information indicates ratio patterns of the at least two time domain units.

3. The device according to claim 2 , wherein the control information is carried in a physical signaling.

4. The device according to claim 1 , wherein the period is equivalent to a periodicity of sending a broadcast control channel.

5. The device according to claim 1 , wherein the time domain unit comprises 14 time slots.

6. 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; wherein:
the transceiver is configured to receive first indication information transmitted by a third device, the first indication information for indicating a time domain unit used by the third device; and

the processor is configured to:
determine the patterns of the at least two time domain units according to the first indication information; wherein the processor is configured to:
determine the time domain unit used by the third device according to the first indication information;
determine a pattern of the first 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 time domain unit used by the third device; and
determine patterns of other time domain units except the first time domain unit in the at least two time domain units, wherein a GP duration of at least one time domain unit in the other time domain units is different from the GP duration of the first time domain unit.

7. The device according to claim 1 , wherein the processor is further configured to:
determine the patterns of the at least two time domain units used in the period according to correspondence between a level of the first device and the patterns of the at least two time domain units.

8. The device according to claim 1 , wherein:
the transceiver is configured to receive second indication information transmitted by a third device, the second indication information for indicating a time domain unit for downlink used by the third device; and
the processor is configured to determine the patterns of the at least two time domain units according to the second indication information.

9. The device according to claim 1 , wherein the special subframe effective time comprises:
a special subframe position; or
a special subframe offset and period.
