Embodiment Construction

[0093] The core of the present invention is to determine the transmission power of the second subframe of the reference special burst in the downlink DTX process, and determine the path loss increase value of the current special burst subframe relative to the second subframe of the reference special burst. The sum of the transmission power of the second subframe of the special burst and the path loss increase value is determined as the transmission power of the current special burst subframe. Specifically, the first special burst in the downlink DTX process can be set as a reference special burst, then in order to determine the transmit power of the second subframe of the first special burst, and determine the current special burst subframe relative to the The path loss increase value of the second subframe of the first special burst, and the sum of the transmit power of the second subframe of the first special burst and the path loss increase value is determined as the current...

Abstract

The invention provides a method for determining the transmitting power of special bursting sub frames, which is applied to the discontinuous transmitting process of downlinks and includes the following steps: determining the transmitting power of reference special bursting second sub frames; determining the increase value of path loss of the current special bursting sub frames comparatively to the reference special bursting second sub frames; determining the sum of the transmitting power of the reference special bursting second sub frames and the increase value of the path loss as the transmitting power of the current special bursting sub frames; the reference special bursting sub frame is a first special bursting second sub frame in the discontinuous transmitting process of the downlinks or the previous special bursting second sub frame in current special bursting transmitted or the special bursting second sub frame currently transmitted in the special bursting period with preset numbers apart before the special bursting sub frames. The invention provides a device which determines the transmitting power of the special bursting sub frames. By adopting the invention, the transmitting power of the current special bursting sub frames can be more accurate so as to improve the call quality in the downlink DTX process and reduce the call drop.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a device for determining the transmission power of a special burst subframe. Background technique [0002] Dedicated data between the network and the user is transmitted over the air in a radio frame format through a dedicated physical channel (Dedicated Physical Channel, DPCH). One radio frame includes two subframes. [0003] In order to reduce inter-channel interference and improve system capacity, existing wireless communication systems use Discontinuous Transmission (DTX) technology. The following DTX is taken as an example, specifically: during the silent period of the call process, the upper layer of the base station (NodeB) has no data allocated to the DPCH, that is, the NodeB has no data subframe to be sent to the user terminal (User Equipment, UE) through the DPCH, but Periodically send a special burst (Special Burst) to the UE on th...
