Embodiment Construction

[0020] The following examples are in the context of E-UTRA systems, including future releases, such as those of LTE-Advanced (LTE-A), which are now expected, but these radio access technology contexts are not limited to the broader teachings herein . In other deployments, these teachings for reporting channel state may be used by other types of radio access technologies (RATs) that may be developed for 4-TxMIMO / CoMP, including but not limited to Wideband Code Division Multiple Access and the now established Or other radio technologies yet to be developed.

[0021] These teachings are best understood in comparison to current methods for codeword construction and selection. As mentioned above, more complex CSI feedback includes PMI, CQI and RI. Traditional LTE allows wideband or per subband reporting of CQI and PMI, where a reporting subband consists of a certain integer number of physical resource blocks (PRBs), where the number of PRBs depends on the system bandwidth and the...

Abstract

A double structured codebook is described that has a wideband codebook portion C(W1) and a frequency-selective codebook portion C(W2). Portion C(W2) is characterised in that for at least one rank index RI, each codeword of C(W2) is uniquely distinguished over all other codewords of C(W2) by at least two beam selection vectors per layer. A device (UE, eNB, etc) utilises the at least two different beam selection 10 vectors per layer to uniquely select a codeword W 2 from C(W2) (404); and constructs a precoder W from the selected codeword W2 and from another codeword W1 selected from the wideband codebook portion C(W1) for signalling channel conditions (406). An additional co-phasing term for ensuring orthogonality can be utilised with the beam selection vectors per layer to uniquely select the codeword from C(W2), and the two different beam selection vectors per layer correspond to different polarizations (410).

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119 and 37 CFR §1.55, this application claims the benefit of UK Patent Application No. 1304108.2, filed March 7, 2013, the entire contents of which application are hereby incorporated by reference. technical field [0003] The present invention relates to a method, device and computer program for controlling a wireless device. The exemplary and non-limiting embodiments of the present invention relate generally to wireless communication systems, methods, apparatus, and computer programs, and specific examples relate to wireless multipath communications, such as multiple-input / multiple-output (MIMO) and cooperative multiple point (CoMP) communication, the codebook. Background technique [0004] Multipath communication is well known in wireless technology and is used to improve spectral efficiency. For example, the 3rd Generation Partnership Project (3GPP) Evolved Universal Terrestrial Radio Acces...
