Problems solved by technology

[0007] In the first stage of wireless link establishment, Out-of-sync will not be reported. For the transmission frequency of the special burst that replaces the uplink DPCH, when using the gain factor to calculate its transmission power, especially in the case of the cell edge, There will be insufficient transmit power, which will cause the base station to receive signal errors. Since Out-of-sync will not be reported during this period, the terminal or base station cannot judge out-of-sync, resulting in received data errors

Embodiment Construction

[0027] The basic idea of ​​the present invention is: the establishment of the wireless link is divided into the first stage and the second stage. In the first stage, when the terminal sends a special burst, the transmission power of the special burst The power is calculated; in the second stage, when the terminal sends a special burst, the transmission power of the special burst is calculated according to the transmission power and gain factor of the uplink DPCH.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The present invention provides a method for calculating the transmission power of a special burst, figure 2 is a schematic flow chart of the method for calculating the transmit power of a special burst in the present invention, such as figure 2 As shown, the method includes the following steps:

[0030] Step 201, a radio network controller (RNC, Radio Network Contr...

Abstract

The invention discloses a method for calculating the transmission power of a special burst. The establishment of a wireless link is divided into a first stage and a second stage. In the first stage, when a terminal sends a special burst, the special burst The transmit power is calculated according to the transmit power of the uplink packet data channel (DPCH); in the second stage, when the terminal sends a special burst, the transmit power of the special burst is calculated according to the transmit power and gain factor of the uplink DPCH ; The present invention also provides a terminal for calculating the transmit power of a special burst. According to the technical scheme of the present invention, the out-of-synchronization problem caused by relatively low power of special bursts in the first stage of establishing a wireless link of a terminal can be solved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and terminal for calculating the transmission power of a special burst. Background technique [0002] In a communication process, the mobile user only has very little time for talking, because the mobile user actually only has very little time for talking, most of the time does not transmit voice messages, when the mobile user does not talk, the terminal The device related to the call will enter the off state. Only when the paging cycle is reached, the terminal will receive the network message and judge whether there is an information update. If there is an update, the terminal will perform uplink synchronization, and the network will know that the terminal is the object to be paged. Furthermore, a connection between the terminal and the calling terminal is established. Therefore, during the interval between paging cycles, the network will not send network messages t...
