Benefits of technology

The present invention allows for efficient transmission and reception of control information over multiple carriers with different frequencies used by both the base station device and the mobile phone. This helps improve communication quality and efficiency.

Problems solved by technology

This patent describes a technical problem addressed in this patent text relates to improving the performance of wireless communication systems while reducing interference between carriers. One solution involves dividing the frequency resources into smaller parts called resource subsets, allowing for better allocation of resources within the wider range of frequency bands. Additionally, the patent proposes introducing a new method for controlling the transmission power of signals in both the downlink and uplink directions simultaneously during the time period of the uplink communication.

first embodiment

[0088]A first embodiment of the mobile communication system using the base station apparatus 100 and the mobile station apparatuses 200 will now be described. In the first embodiment, the base station apparatus 100 semi-statically sets the first PUCCH to the mobile station apparatus 200, and dynamically sets the second PUCCH to the mobile station apparatus 200 in the same subframe as the subframe in which the first PUCCH is set; the mobile station apparatus 200 uses the first PUCCH and the second PUCCH, and thereby can transmit the control information of HARQ to the base station apparatus 100. The base station apparatus 100 semi-statically sets the first PUCCH to the mobile station apparatus 200, and dynamically sets the second PUCCH to the mobile station apparatus 200 in the same subframe as the subframe in which the first PUCCH is set; the mobile station apparatus 200 uses the first PUCCH or the second PUCCH, and thereby can transmit the control information of HARQ to the base statio

second embodiment

[0124]The second embodiment of the present invention will now be described. In the second embodiment, the base station apparatus 100 semi-statically sets the first PUCCH to the mobile station apparatus 200, transmits, to the mobile station apparatus 200, information indicating activation and / or deactivation for the downlink component carrier and dynamically sets the second PUCCH to the mobile station apparatus 200 in the same subframe as the subframe in which the first PUCCH is allocated whereas the mobile station apparatus 200 uses the first PUCCH and / or the second PUCCH activated according to the information indicating the activation and / or the deactivation, and thereby can transmit the control information of HARQ to the base station apparatus 100. Moreover, the base station apparatus 100 semi-statically sets the first PUCCH to the mobile station apparatus 200, transmits, to the mobile station apparatus 200, information indicating the activation and / or the deactivation for th

Abstract

In a mobile communication system in which a plurality of component carriers are used, transmitting and receiving control information of HARQ effectively is realized. In a mobile communication system in which a base station apparatus (100) sets a plurality of downlink component carriers for a mobile station apparatus (200), the base station apparatus (100) transmits a downlink transport block to the mobile station apparatus (200) on one or a plurality of downlink component carriers among the plurality of downlink component carriers, and the mobile station apparatus transmits, to the base station apparatus (100), control information of HARQ for the downlink transport block on any one of physical uplink control channel resources corresponding to the one or plurality of downlink component carriers on which the downlink transport block has been transmitted.
