Abstract: Methods and apparatus for wireless communication in a wireless communication network include determining a transmit data packet size at a transmitting device and computing an early termination scheme associated with a receiving device. Aspects of the methods and apparatus include increasing a transmission length of a Cycle Redundancy Check (CRC) field associated with the transmit data packet before transmission of the transmit data packet, wherein the transmitted length of the CRC field is based on the early decoding scheme. Aspects also include transmitting the transmit data packet with the increased transmission length of the CRC field to the receiving device.

Abstract: One or more scheduling grants may be received from a Node B related to a plurality of uplink MIMO streams. A determination may be made as to a primary transport power and a primary transport block size for a primary stream. A secondary transmit power and a secondary transport block size for a secondary stream may also be determined. An enhanced relative grant channel from the Node B, as well as another E-RGC from a non-serving Node B may be received for each of the plurality of uplink MIMO streams.

Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.

Abstract: Disclosed are apparatus and method for time division multiplexing of a dedicated channel. In one aspect, the apparatus and method are configured to assign a common spreading code to two or more User Equipments (UEs); encode a downlink (DL) dedicated channel (DCH) with the common spreading code; time-division multiplex a Dedicated Physical Data Channel (DPDCH) data for each of the two or more UEs on the encoded DL DCH; and transmit the multiplexed data on the DL DCH to the UEs.

Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an E-TFC selection process for selecting a transport format combination for an uplink MIMO transmission may take certain steps in the case that a UE is power- or buffer-limited. For example, in a rank 2 transmission, non-scheduled data is allocated only to the primary stream. If the allocated non-scheduled data is less than the determined primary stream transport block size, scheduled data is allocated to the primary stream in an amount not to exceed the determined primary stream TBS. Finally, scheduled data is allocated to the secondary stream in an amount not to exceed the determined secondary stream TBS.

Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an uplink MIMO transmission (e.g., a rank 2 transmission) may be established, wherein a primary stream transport block size (TBS) is determined in accordance with a received scheduling grant, and a modulation scheme for the transmission is determined in accordance with the TBS. Further, a predetermined spreading factor, such as a 2×SF2+2×SF4 spreading factor, may be configured for both uplink streams, independent of the TBS. Finally, the uplink MIMO transmission may be made in accordance with the determined TBS, modulation scheme, and spreading factor. In some examples, if the primary stream TBS or a determined secondary stream TBS is less than a minimum threshold TBS, the transmission may be reconfigured as a rank 1 transmission.

Abstract: Systems and methodologies are described that facilitate combining received signals from multiple receive antennas in a wireless communication environment. The received signals from the multiple receive antennas can be weighted utilizing an adaptive combination of maximal ratio combining (MRC) and interference nulling. The combination of MRC and interference nulling can be controlled based upon one or more configurable parameters. For instance, a covariance matrix can be modified to include the one or more configurable parameters, and the modified covariance matrix can be utilized in connection with interference nulling. Further, respective values for the one or more configurable parameters can be selected as a function of at least one input (e.g., measured interference-over-thermal (IoT) value, received loading level indicator, eigenvalue distribution of a covariance matrix, . . . ) related to noise correlation.
