Method and device for power control in non-adaptive retransmission

摘要

The disclosure discloses a method and device for power control in non-adaptive retransmission. The solution thereof includes: when UE does not obtain a TPC adjustment value of a current HARQ process by parsing, determining a current power control mode; if the mode is an accumulation mode, determining whether the calculated sum of TPC adjustment values of each HARQ process is smaller than a given threshold, if yes, obtaining a transmission power by adding an increment adjustment value to a retransmission power, otherwise, calculating the transmission power of UE according to a formula in a protocol; if the mode is an absolute value mode, obtaining a transmission power by adding an increment adjustment value to a retransmission power. The solution can improve the SINR detected by an eNB and improve a retransmission success rate, thereby saving radio resources, facilitating utilization of radio resources and reduction of transmission delay, improving the throughput rate of an LTE system and improving the system performance.

1. A method for power control in non-adaptive retransmission, comprising:
determining a current mode of power control when User Equipment (UE) does not obtain a Transmit Power Control (TPC) adjustment value of a current retransmission Hybrid Automatic Repeat Request (HARQ) process by parsing; when the mode of the power control is an accumulation mode, determining whether a calculated sum of TPC adjustment values of each HARQ process is smaller than a given threshold; if it is smaller than the given threshold, then obtaining a transmission power by adding an increment adjustment value to a retransmission power, otherwise, calculating a transmission power of the UE according to a formula in a protocol; when the mode of the power control is an absolute value mode, obtaining a transmission power by adding an increment adjustment value to a retransmission power.
