Communication method in time division duplex system, base station, and user equipment

A base station, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the processor, the programming instructions instruct the processor to:
• determine radio frame configuration information, wherein the radio frame configuration information is used to instruct at least one of:
• configuring each uplink subframe of one radio frame to two same consecutive uplink subframes of reduced length, wherein a total length of the one radio frame remains unchanged;
• configuring each downlink subframe of the one radio frame to two same consecutive downlink subframes of reduced length, wherein the total length of the one radio frame remains unchanged;
• or
• configuring each special subframe of the one radio frame to two same consecutive special subframes of reduced length, wherein the total length of the one radio frame remains unchanged;
• send the radio frame configuration information to a user equipment (UE);
• and
• communicate with the UE by using the radio frame configured according to the radio frame configuration information.

A user equipment (UE), comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the processor, the programming instructions instruct the processor to:
• receive radio frame configuration information sent by a base station, wherein the radio frame configuration information is used to instruct at least one of:
• configuring each uplink subframe of one radio frame to two same consecutive uplink subframes of reduced length, wherein a total length of the one radio frame remains unchanged;
• configuring each downlink subframe of the one radio frame to two same consecutive downlink subframes of reduced length, wherein the total length of the one radio frame remains unchanged;
• or
• configuring each special subframe of the one radio frame to two same consecutive special subframes of reduced length, wherein the total length of the one radio frame remains unchanged;
• and
• communicate with the base station by using the radio frame determined according to the radio frame configuration information.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor in a user equipment (UE), configures the processor to:

• receive radio frame configuration information sent by a base station, wherein the radio frame configuration information is used to instruct at least one of:
• configuring each uplink subframe of one radio frame to two same consecutive uplink subframes of reduced length, wherein a total length of the one radio frame remains unchanged;
• configuring each downlink subframe of the one radio frame to two same consecutive downlink subframes of reduced length, wherein the total length of the one radio frame remains unchanged;
• or
• configuring each special subframe of the one radio frame to two same consecutive special subframes of reduced length, wherein the total length of the one radio frame remains unchanged;
• and
• communicate with the base station by using the radio frame determined according to the radio frame configuration information.
