    Abstract: 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.

    Abstract: Uplink precoding in closed loop transmit diversity (CLTD). The methods and apparatus relate to precoder operations during an initial stage using default precoder tap weights, and a second stage wherein precoder weights obtained from a precoder control indicator channel information are used, provided the signal quality of the precoder control indicator channel is sufficiently reliable. The methods and apparatus also relate to procedures for responding to detection of an unreliable pre-coding control information (PCI) carried in a downlink feedback signal.

    Abstract: A dedicated grant may be shared by a group of WTRUs for performing uplink communications. A WTRU in a group may use the dedicated grant when it receives a group identifier and/or a WTRU identifier that are associated with the WTRU. The uplink communications from each WTRU transmitting in a group may be time-aligned. WTRUs may be allowed to transmit on the uplink channel using the dedicated grant for a designated time period. The WTRU may perform uplink control using MCS configurations controlled by the network. The WTRU may receive an indication of the MCS parameters or an MCS adjustment that may be applied to uplink communications. Uplink communications may be performed using an active non-scheduled transmission mode of operation or an inactive non-scheduled transmission mode of operation. Uplink load balancing may be performed by the network during dynamic frequency handover to manage the data packets being transmitted.

    Abstract: Feedback information for multiple serving cells are transmitted on high speed dedicated physical control channel (HS-DPCCH). A slot format for transmitting feedback information is determined based on the number of configured secondary serving cells and whether multiple input multiple-output (MIMO) is configured in the serving cells. Spreading factor is reduced to 128 when two secondary serving cells are configured and MIMO is configured in at least one of the two configured secondary serving cells, or when three secondary serving cells are configured. The serving cells are grouped into feedback groups, each feedback group having one or more serving cells. Channel coding may be applied to feedback information for the feedback groups. The resulting encoded feedback information for the feedback groups is concatenated to form composite feedback information.

    Abstract: Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) to determine rank, offset, or inter-stream interference control information, for example, which may be associated with uplink MIMO operations. A method to control a WTRU may include receiving a special E-RNTI that is associated with a channel. The channel may be associated with a rank indication. The channel may be an E-AGCH-like channel. The channel may have a similar encoding structure as an E-AGCH. The channel may be an E-ROCH. The channel may be received, and it may be determined that the channel is associated with the special E-RNTI. At least one of a rank or an offset may be determined, and the WTRU may be configured with the determined rank or offset. An inter-stream interference (ISI) offset may be received, for example, via RRC signaling, and may be applied to an uplink transmission of a primary stream.
