    Abstract: A method and an apparatus for performing multiple-input multiple-output (MIMO) wireless communications are disclosed. A Node-B may receive an index to a pre-coding matrix in a single user MIMO (SU-MIMO) pre-coding codebook from wireless transmit/receive units (WTRUs) and adaptively perform one of SU-MIMO or multi-user MIMO (MU-MIMO) based on a predetermined criterion. Channel information for performing MU-MIMO may be obtained based on the pre-coding matrix of the SU-MIMO pre-coding codebook. A rank requested by the WTRU may be overridden if the unitary MU-MIMO codebook is a subset of the SU-MIMO pre-coding codebook. If not, a MU-MIMO pre-coding matrix with a largest correlation to the pre-coding matrix may be selected. A WTRU may send a pre-coding matrix for transmission to the WTRU along with a preferred interference matrix. A WTRU may send rank information and multiple right singular vectors for MU-MIMO.

    Abstract: A power control scheme for an enhanced Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) physical uplink shared channel (PUSCH) is disclosed. In a first embodiment, when an uplink grant is configured for accumulation commands, the wireless transmit/receive unit (WTRU) combines the accumulation commands received in both the scheduling grant and the transmit power control physical downlink control channel. In a second embodiment, when an uplink grant is configured for absolute commands, the WTRU resets the accumulation control function immediately after receiving each absolute transmit power control command and then combines the absolute power control with the accumulation power control.

    Abstract: A method and apparatus for signaling interference information in a multi-user multiple-input multiple-output (MU-MIMO) system including a plurality of wireless transmit/receive units (WTRUs) and a base station are disclosed. The method includes the base station signaling interference information including rank information or a number of WTRUs to a particular WTRU based on beamforming vector feedback information received from the WTRUs. In order to reduce the downlink signaling overhead, confirmation of the beamforming vector feedback from WTRUs is used. The interference beamforming vectors and rank information or the number of WTRUs can be signaled separately or jointly.

    Abstract: Apparatus and method of generating a long term evolution (LTE) codebook and performing rank overriding are disclosed. Reordering rules are presented, whereby a second column vector of each rank-4 precoding matrix will not appear in column vectors of a rank-3 precoding matrix, and the first column vector of each rank-4 precoding matrix is identical to the first column vector of the corresponding rank-3 precoding matrix. Furthermore, precoder hopping between two precoding matrices corresponding to a particular precoding matrix index (PMI) is implemented, whereby a first one of the two precoding matrices comprises a first subset of column vectors of an original precoding matrix that corresponds to the particular PMI, and a second one of the two precoding matrices comprises a second subset of column vectors of the original precoding matrix. The precoder hopping is performed in time and/or frequency domain.

    Abstract: The transmission and decoding of resource blocks (RBs) transmitted via a multiple-input multiple-output (MIMO) antenna having a plurality of transmit antennas is disclosed. Each RB includes a plurality of resource elements (REs). Each RE is reserved for one of a common reference signal (CRS) associated with one of the transmit antennas, a dedicated reference signal (DRS) including a single beamformed or precoded pilot, a DRS including a composite beamformed or precoded pilot, and a data symbol. Each RB may include a "control type" data symbol that indicates a DRS mode associated with the RB. In one DRS mode, each DRS includes a single beamformed or precoded pilot. In another DRS mode, each DRS includes a composite beamformed or precoded pilot. In yet another DRS mode, single beamformed or precoded pilots, and composite beamformed or precoded pilots, may coexist and be transmitted simultaneously within the same RBs or in different RBs.

    Abstract: Methods and apparatus for communicating precoding or beamforming information to users are disclosed. A feedback signal including a reported precoding matrix index (PMI) is received and a determination made as to the state of the feedback. Precoding rules associated with the determined state are then used to select a precoding matrix. The state information is transmitted to a wireless transmit receive unit (WTRU), which uses the state information and the precoding rules associated therewith to select the precoding matrix used to precode a received precoded data signal.

    Abstract: Joint detection is performed in a multi-user detector (MUD) using reduced length channel impulse responses and using interference cancellation (IC) in the dimension of delay spread as a whole, whereby several clusters of smaller delay spread are processed. Several clusters of real transmitted paths that are close to each other are grouped together and zeros that occur between the path cluster groups are discarded. Each cluster group has a much shorter delay spread and thus has smaller dimensions of system matrix A. Mutual interference occurring between the path cluster groups is eliminated by applying an interference cancellation technique.

    Abstract translation: 在多用户检测器（MUD）中使用减小的长度信道脉冲响应并且在整个延迟扩展的维度中使用干扰消除（IC）来执行联合检测，从而处理较小延迟扩展的几个簇。 彼此靠近的几个实际传输路径的群集被分组在一起，并且丢弃在路径群集组之间发生的零。 每个簇组具有更短的延迟扩展，因此具有较小的系统矩阵A的维度。通过应用干扰消除技术来消除路径簇组之间发生的相互干扰。
