Abstract: In a wireless communication system comprising at least one evolved Node-B (eNB) and a plurality of wireless transmit/receive units (WTRUs), a non-contention based (NCB) channel is established, maintained, and utilized. The NCB channel is allocated for use by one or more WTRUs in the system for utilization in a variety of functions, and the allocation is communicated to the WTRUs. The wireless communication system analyzes the allocation of the NCB channel as required, and the NCB channel is reallocated as required.

Abstract: A method and apparatus may be used for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI). A transmitter and a receiver may include a plurality of H-ARQ processes. Each H-ARQ process may transmit and receive one TB per TTI. The transmitter may generate a plurality of TBs and assign each TB to a H-ARQ process. The transmitter may send control information for each TB, which may include H-ARQ information associated TBs with the TBs. The transmitter may send the TBs using the associated H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver may send feedback for each of the H-ARQ processes and associated TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The feedback for multiple TBs may be combined for the simultaneously transmitted H-ARQ processes, (i.e., TBs).

Abstract: A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of wireless user terminals. Each wireless user terminal includes a receiver and a controller configured to receive a plurality of orthogonal frequency division multiplexing (OFDM) signals on at least one downlink carrier frequency. Each of the plurality of OFDM signals includes assignment information. The receiver is configured to receive a plurality of downlink signals each responsive to a respective OFDM signal of the plurality of OFDM signals such that each downlink signal is received on a downlink carrier frequency and using a downlink spatial pattern. Further, the controller is configured to dynamically change the downlink carrier frequency of the receiver for receiving the plurality of downlink signals based on the plurality of OFDM signals, wherein the plurality of downlink signals have different spatial patterns.

Abstract: Channel state information (CSI) that includes a first channel quality indicator (CQI) for a first group of subcarriers and a second CQI for a second group of subcarriers may be received. For the first and second group of subcarriers, a number of streams for spatial multiplexing and modulation and coding schemes based on respective CQIs may be determined.

Abstract: A method and wireless transmit/receive unit (WTRU) for uplink transmission are disclosed. A WTRU receives configuration information. The configuration information includes logical channel priority information and a maximum number of hybrid automatic repeat request (HARQ) transmissions. For a transmission time interval (TTI), the WTRU identifies a HARQ process to use for uplink transmission for the TTI on a condition that an uplink grant is for the TTI. The WTRU selects data for uplink transmission for the TTI. For a new uplink transmission, data is allocated in decreasing order of priority based on the logical channel priority information. The WTRU initializes a transmission counter. The transmission counter indicates a number of transmissions associated with the selected data. The WTRU transmits the selected data over an uplink channel based on the uplink grant using the identified HARQ process.

Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.
