Method for regulating inversed business channel power

Abstract

This invention discloses a method for adjusting reverse service channel power including the following steps: A, an access terminal sends reverse data packets to the network side, which decodes them to record the decoded sub-packet number N if the decoding is successful and enquires to get the corresponding terminal target based on the transmission mode and sizes of the decoded reverse data packets, B, comparing the numbers of the terminated target and the sub-packet to determine the T2P of the adjusted service channel to the reverse pilot frequency to be sent to the access terminal, C, the access terminal adjusts the transmission power of the reverse data packets corresponding to the transmission mode and packet size based on the T2P.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for adjusting reverse service channel power. Background technique [0002] In the initial Rev 0 version of the new data service (Evolution Data Optimized, EV-DO) of the Code Division Multiple Access (CDMA) 2000 system, the access terminal (Access Terminal, AT) sends the base station (Base Transceiver Station, The reverse data sent by BTS) is sent in frames, and each frame takes 26.67ms. In the current latest Rev A version, in order to increase the reverse rate, each reverse data packet (Packet) is divided into 4 subpackets, each subpacket corresponds to a subframe, and the subframes are sent alternately. [0003] figure 1 Shown is a schematic diagram of EV-DO Rev 0 and Rev A sending reverse data packets. There are three data packets, namely, packet A, packet B, and packet C. In the Rev 0 version, these three data packets are sent sequentially; in the Rev ...

AI Technical Summary

Problems solved by technology

[0007] 1. The method of reverse power adjustment is to uniformly increase the power of the pilot, thereby indirectly increasing the power of all packets. In fact, only the data packets in the LL mode may need to increase the power, which will lead to a decrease in the reverse power of the HC mode data packets. waste;

[0008] 2. When the HC mode and LL mode reverse data packets are sent alternately, the LL mode data packets increase the power of the reverse traffic channel, and the subsequent HC mode data packets reduce the power, resulting in unnecessary frequent reverse traffic Channel Power Adjustment
