UE Based Conditional Enabling of ULTD |
摘要 |
In a communication system, user equipment (UE) conditionally performs uplink transmit diversity (ULTD) either by Switched Antenna Transmit Diversity (SATD) or Beamforming Transmit Diversity (BFTD) using a first antenna and a second antenna. Either a serving node or the UE determines that uplink transmit diversity is conditionally authorized. Either a serving node or the UE measures a value. The UE transmits using ULTD in response to determining that an enabling condition based on the value is satisfied. The UE can also disable uplink transmit diversity in response to determining that a disabling condition based on the value is satisfied. The disabling condition comprises a disabling threshold that equals the enabling condition comprising an enabling threshold with a threshold adjustment for hysteresis. |
