摘要： Methods and apparatus for preventing physical hybrid automatic repeat request (HARQ) indicator channel (PHICH) ambiguities or collisions, for example, in a multi-carrier system or when transmitting multiple streams over multiple antennas, are described. Methods may include dividing resources or groups among multiple component carriers (CCs), using and assigning unused or vacant resources to CCs, forcing usage of adaptive HARQ processes in specified scenarios, setting a value for the cyclic shift of the corresponding uplink demodulation reference signals (DMRS) to a previous value for semi-persistent scheduling, and assigning a different first resource block for semi-persistent scheduling uplink resources and random access response grants for multiple CCs.

摘要： A method and apparatus for half-duplex (HD) frequency division duplex (FDD) (HD-FDD) operation are disclosed. The method in a wireless transmit/receive unit (WTRU) includes monitoring a first frequency for all downlink sub-frames for downlink communication except during a cell specific uplink frame, retuning to a second frequency and transmitting a scheduling request (SR) during a WTRU specific period of the cell specific uplink frame, wherein the WTRU specific period is based on a duty cycle, and retuning to the first frequency and receiving an uplink grant in a subsequent sub-frame.

摘要： Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

摘要： Communications may be performed in a communications system using multi-dimensional antenna configurations. A WTRU may receive communications from a base station via one or more channels. The communications may be performed using multiple component codebooks. The WTRU may send channel state information (CSI) feedback for each component codebook to the base station for consideration when performing communications with the WTRU. The WTRU may determine the CSI feedback for each component codebook based on channel measurements. The component codebooks may include a horizontal component codebook and/or a vertical component codebook. The WTRU may send the CSI feedback for each component codebook to the base station independently or in the form of a composite codebook. The WTRU may determine a composite codebook a function of the component codebooks.
