Embodiment Construction

[0037] Please refer to figure 1 , figure 1 It is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention. The wireless communication system 10 can be an advanced long term evolution (Long Term Evolution Advanced, LTE-A) system, and supports relay stations, coordinated multiple point (Coordinated Multiple Point, CoMP) transmission and can transmit simultaneously on multiple component carriers and Receive data, such as carrier aggregation (Carrier Aggregation) technology. For the convenience of illustrating the concept of the present invention, the wireless communication system 10 is only shown to include a mobile device 12 and base stations 14-18 respectively controlling the cells CE1-CE3, wherein the base stations 14, 16 are respectively deployed with relay stations 22, 24, which respectively have signal Coverage RA1, RA2. In the LTE-Advanced system, the network end is an evolved universal terrestrial radio access networ...

Abstract

A method for enhancing power control mechanism for a mobile device in a wireless communications system includes enabling a repetition function by which the mobile device repeatedly transmits a feedback signal in a plurality of consecutive subframes, receiving a first downlink signaling indicating an uplink grant as well as a power control command and allocation of a frist subframe of a first uplink transmission, and not performing the first uplink transmission in the first subframe when the first subframe collides with one of the consecutive subframes.

Description

technical field [0001] The present invention refers to a method for a wireless communication system and its related communication device, especially a method for improving a power control mechanism in a wireless communication system and its related communication device. Background technique [0002] The Long Term Evolution (LTE) system formulated by the 3rd Generation Partnership Project (3GPP) is currently considered to provide high data transmission rate, low latency, packet optimization and improved A new wireless interface and wireless network architecture for system capacity and coverage. In the LTE system, an evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) that plays the role of a wireless access network includes an evolved wireless base station (evolved Node-B, eNB), which On the one hand, it can communicate wirelessly with the mobile device (or called the client (User Equipment, UE)), and on the other ...
