摘要： A wireless transmit/receive unit (WTRU) receives a downlink transmission from an eNodeB including a plurality of spatial layers transmitted to a plurality of WTRUs paired for multi-user MIMO. The WTRU decodes the downlink transmission based on a corresponding WTRU-specific reference signal. WTRU-specific reference signals are multiplexed using a frequency and code division multiplexing. WTRU-specific reference signals for different sub-group of antenna ports are multiplexed onto different subcarriers in a frequency domain and the WTRU-specific reference signals of the same sub-group of antennas ports are multiplied by an orthogonal cover code. The resource elements used for the WTRU-specific reference signals on antenna ports in one sub-group may be muted on antenna ports in another sub-group. A WTRU may transmit the uplink demodulation reference signal without precoding. The number of resource blocks allocated for the demodulation reference signal may be greater than the number of resource blocks allocated for the payload.

摘要： Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.

摘要： Methods and systems for enabling MU-MIMO functions on a UE are disclosed. A precoder codebook with precoding matrices can be generated to assist in improving system throughput. Existing specifications designed for two bit precoding information can be used to communicate higher numbers of bits of precoding information by reinterpreting fields described by such specifications.

摘要： Techniques for transmit power control for multiple antenna transmissions in an uplink are disclosed. A wireless transmit/receive unit (WTRU) generates at least one input stream for transmission and applies a gain factor to each channel. The gain factor is determined based on a reference channel power estimate. The WTRU generates at least two data streams from the input stream for transmission via a plurality of antennas and applies weights to the data streams. The gain factor and/or the weights are controlled such that a transmit power on each antenna is within a maximum allowed value. The WTRU may perform power scaling on a condition that a transmit power on any antenna exceeds the maximum allowed value. The WTRU may scale down an enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) first before other channels. For multiple E-DCH streams, the WTRU may calculate an E-DPDCH power offset based on an additional power offset factor due to multiple stream transmission.
