Embodiment Construction

[0065] Embodiments of the invention are described herein below by way of example with reference to the accompanying drawings.

[0066] It is to be noted that for the purposes of this description, the terms "physical resource block / user bandwidth and user equipment" are examples of "resource block and terminal" respectively, without limiting the latter-named terms to special techniques applied to the first-named term or implementation details.

[0067] Figure 1A showing a first example of a multi-BW multi-user MIMO arrangement (4 UEs and 4 PRBs / user BW) providing MIMO transmission with efficient fractional rank, and Figure 1B A second example of a multi-BW multi-user MIMO arrangement (2 UEs and 3 PRBs / user BW) providing MIMO transmission with efficient fractional rank is shown.

[0068] exist Figure 1A and 1B In the arrangement shown, M (physical) resource blocks ( Figure 1A : M=4, BW 1 to BW 4 ; Figure 1B : M=3, BW 1 to BW 3 ) are assigned to UEs paired for MU-MIMO...

Abstract

Embodiments provide a method and apparatus wherein respective demodulation reference signals, DM RS, of a user bandwidth can be cyclically shifted with respect to each other. An uplink scheduling grant may comprise an index for DM RS resource having a cyclic shift and an orthogonal cover code or interleaved frequency division multiple comb wherein a usage orthogonal cover or interleaved frequency division multiple comb may configured using radio resource control message. A usage orthogonal cover or interleaved frequency division multiple comb may optionally be tied statically into DM RS resources. At least some of respective demodulation reference signals of the at least two user bandwidths may be mutually orthogonal.

Description

technical field [0001] The present invention relates to resource allocation eg for use in multi-BW (bandwidth) MU (multi-user) MIMO (multiple-input multiple-output) arrangements in UL (uplink) transmissions. More specifically, the present invention relates to methods, devices, systems and related computer program products for resource allocation, e.g. in virtual MIMO and SDMA (Space Division Multiple Access) and to where e. The same physical resources (such as frequency and time) are used, for example, for the case of UL transmission. Background technique [0002] In 3GPP LTE (3rd Generation Partnership Project Long Term Evolution), there have been discussions related to resource allocation. [0003] The upper limit of the rank of a MIMO transmission (described herein below with reference to Figure 1 ) is bounded, for example, by the number of receive antennas available at the receiver. However, separation and reliable detection of the transmitted signals often become diff...
