Embodiment Construction

[0080] The following paragraphs describe various embodiments of the invention. For exemplary purposes only, most of the embodiments are described with respect to orthogonal single-carrier uplink radio access schemes according to the 3GPP LTE (Release 8) and LTE-A (Release 10) mobile communication systems explained in the Background section above . It should be noted that the present invention may be advantageously used, for example, in relation to mobile communication systems such as the previously described 3GPP LTE (Release 8) and LTE-A (Release 10) communication systems, but the invention is not limited to its use in this particular exemplary communication network. use in .

[0081] The descriptions given in the background section above are intended to better understand most of the 3GPP LTE (Release 8) and LTE-A (Release 10) specific exemplary embodiments described herein, and should not be construed as limiting the present invention Restricted to specific implementations...

Abstract

The invention relates to methods and apparatuses for providing HARQ feedback in a mobile communication system using carrier aggregation. To suggest a scheme for transmitting feedback on the successful / unsuccessful decoding of transmissions that is operable in FDD mode, the invention proposes to utilize only a single one of plural radio resources available for feedback transmission for signaling feedback for multiple transmissions. A feedback sequence of ACK / NACKs for the transmissions is mapped to one feedback resource combination that is one of the radio resources available for feedback transmission and a modulation symbol of the given modulation scheme that is transmitted on said one radio resource. This scheme can also be used in cases where the number of possible feedback sequences of ACK / NACKs for the transmissions is larger than the number of feedback resource combinations available for feedback transmission.

Description

technical field [0001] The present invention relates to a method for providing feedback, such as HARQ feedback, in a mobile communication system. Furthermore, the present invention also provides hardware structures (such as sending means and receiving means) for carrying out the methods and software-based implementations of the methods presented here. Background technique [0002] Long Term Evolution (LTE) [0003] Third generation mobile systems (3G) based on WCDMA radio access technology, such as UMTS (Universal Mobile Telecommunications System), are currently deployed on a large scale worldwide. The first step in enhancing or evolving this technology requires the introduction of High Speed ​​Downlink Packet Access (HSDPA) along with enhanced uplink (also known as High Speed ​​Uplink Packet Access (HSUPA)) to give a highly competitive radio access technology. [0004] In order to prepare for further increased user demands and to be competitive with new radio access tech...
