Abstract
In aspects, methods and apparatus for utilizing a reconfiguration timer for updating TDD configuration are provided. Certain aspects of the present disclosure propose methods and apparatus for improving system performance while using adaptive uplink-downlink reconfiguration in a time division duplex (TDD) system. For certain aspects, a reconfiguration timer may be utilized along with a signaling scheme, in order to enjoy benefits of the adaptive uplink-downlink reconfiguration with minimum signaling overhead.
Claims30
A method for wireless communications by a base station, comprising:
- selecting a signaling mechanism for dynamically indicating an uplink-downlink configuration for time division duplex (TDD) operation;
- selecting a reconfiguration timer value from a set of one or more reconfiguration timer values;
- informing a user equipment (UE) of the selected signaling mechanism and the selected reconfiguration timer value;
- and
- transmitting reconfiguration signals to the UE according to the selected signaling mechanism and the selected reconfiguration timer value.
A method for wireless communications by a user equipment (UE), comprising:
- receiving information regarding a signaling mechanism for dynamically indicating an uplink-downlink configuration for time division duplex (TDD) operation and a reconfiguration timer value;
- and
- receiving reconfiguration signals according to the signaling mechanism and the reconfiguration timer value.
