Method and apparatus for improving interaction between scheduling request procedure and random access procedure |
摘要 |
The present invention provides a method for improving interaction between a Scheduling Request procedure and a Random Access procedure in a user equipment (UE) of a wireless communication system. The method includes steps of triggering a Scheduling Request procedure; repeatedly sending a Dedicated Scheduling Request (D-SR) message on a Physical Uplink Control Channel (PUCCH) until an uplink transmission resource for a new transmission is received or the number of D-SR transmissions reaches to a specific value when the PUCCH is configured for the UE; and deactivating all pre-configured transmission resources before performing a Random Access procedure corresponding to the Scheduling Request procedure when the number of D-SR transmissions reaches to the specific value. |

1. A method for improving interaction between a Scheduling Request procedure and a Random Access procedure in a user equipment (UE) of a wireless communication system, the method comprising:
triggering, a Scheduling Request procedure; sending a Dedicated Scheduling Request (D-SR) message on a Physical Uplink Control Channel (PUCCH) repeatedly until an uplink transmission resource for a new transmission is received or the number of D-SR transmissions reaches to a specific value when the UE has a configured PUCCH resource; and deactivating all pre-configured Semi-Persistent Scheduling (SPS) transmission resources of a SPS operation allocated to the UE before performing a Random Access procedure corresponding to the Scheduling Request procedure when the number of D-SR transmissions reaches the specific value to prevent the UE from misusing the pre-configured SPS transmission resources in a Random Access procedure performed in parallel with the SPS operation so that Random Access procedure failures and uplink transmission errors can be avoided. |
