    摘要: Methods and systems for transmitting scheduling requests in an LTE Advanced system are disclosed. Scheduling requests may be superimposed on HARQ ACK/NACK by multiplying the HARQ ACK/NACK by a value. Alternatively, scheduling requests may be channel-coded and multiplexed with other uplink control information. Scheduling requests can also be superimposed on reference signals by multiplying a reference signal by a value or by modulating a reference signal with a cyclic shift. Scheduling requests may also be jointly coded with HARQ ACK/NACK prior to transmission. Alternatively, ACK/NACK responses may be transmitted on assigned ACK/NACK PUCCH resources for a negative scheduling request transmission and on assigned scheduling request PUCCH resources for a positive scheduling request. Various collision handling mechanisms are also disclosed.

    摘要: Techniques for sending hybrid automatic repeat request (HARQ) feedback for stransmissions received via a plurality of aggregated component carriers are disclosed. A wireless transmit/receive unit (WTRU) receive a plurality of codewords via a plurality of component carriers and decodes the codewords. The component carriers are grouped into a plurality of groups, and the WTRU may generate a bundled positive/negative acknowledgement (ACK/NACK) for each group of component carriers. The WTRU may be assigned a plurality of uplink control channel resources and may implement a channel selection scheme for indicating the ACK/NACKs. The WTRU selects one of the uplink control channel resources, and sets the HARQ feedback based the ACK/NACKs or bundled ACK/NACKs in a way that a different uplink control channel resource is selected and HARQ feedback bits are set differently based on the ACK/NACKs or bundled ACK/NACKs. Each physical uplink control channel (PUCCHs) may be mapped to a particular antenna.

    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.
