Description

Method and device for grouping uplink power control

The present invention relates to the field of mobile communications, and in particular, to a method and a device for grouping uplink power control. Background technique

For the packet uplink closed loop power control, the adjustment of the MS transmit power is determined by the network side according to the measurement result of the uplink quality of the mobile station (MS). As shown in Figure 1, the specific process of packet uplink closed loop power control is as follows:

a Base Transceiver (BTS) measures the reception level and link quality of each Radio Link Control I Medium Access Control (RLC/MAC) radio block transmitted by the MS, and A measurement report of the uplink quality is formed.

The BTS reports the measurement report to the base station controller (BSC). The BSC performs packet uplink closed-loop power decision based on the measurement. When the BSC decides to adjust the transmit power of the uplink PDCH on the MS side, the BSC can use the corresponding The packet uplink closed loop power control algorithm calculates the uplink power control parameters.

The BSC sends the uplink power control parameters to the MS through the downlink RLC/MAC control message, and the MS adjusts the power of the uplink packet data channel (PDCH) according to the uplink power control parameter. It can also be a UPLINK DUMMY CONTROL BLOCK. When performing the extended uplink temporary block flow (TBF) optimization, that is, when the "extended uplink TBF does not send the null control block (EXT_UTBF_NODATA)", the cell parameter is set to 1, when the extended uplink TBF is inactive. If there is no uplink data transmission, the MS does not send an uplink null control block to the network side.

The prior art generally sends an uplink power control parameter to the MS through a packet uplink acknowledgement/deny (PACKET UPLINK ACK/NACK) message to perform packet uplink closed loop power control. but The PACKET UPLINK ACK/NACK message is sent by the BSC to the MS periodically, so that the uplink power control parameters cannot be sent in real time, which causes the uplink closed loop power control to lag or even fail.

In addition, in the extended uplink TBF inactivity period, if the MS does not send the uplink control block to the network side in the prior art, the measurement of the uplink quality by the BTS is prone to fluctuation and instability. The inaccuracy of the uplink quality measurement results will directly affect the effect of the uplink coding mode adjustment algorithm and the uplink closed loop power control effect, resulting in a decrease in the Key Performance Index (KPI) indicator of the existing network.
