    摘要: A method and apparatus for avoiding a collision. A collision may be avoided by allocating a first set of subframes to a backhaul link transmission, and allocating a second set of subframes to an access link transmission. In one example, the second set of subframes may be a non-overlapping set of subframes with respect to the first set of subframes. In a second embodiment, a collision may be avoided by receiving a data transmission from an evolved Node-B (eNB) and transmitting an uplink (UL) grant to a wireless transmit/receive unit (WTRU) and a first acknowledgement (ACK) to the eNB. The transmission may be in response to the received data transmission. The RN may avoid a collision by further transmitting an automatic ACK to the WTRU and transmitting a second UL grant to the WTRU. In a third embodiment, a collision between an access link transmission and a backhaul link transmission may be avoided by detecting a collision and determining an interface priority based on a collision occurrence type.

    摘要: Methods and apparatus for sounding reference signals (SRS) configuration and transmission. The methods include receiving configuration of wireless transmit/receive unit (WTRU)-specific SRS subframes for transmitting SRS and upon receipt of a trigger, transmitting the SRS for a number of antennas. The SRS transmissions may occur in each subframe of a duration of WTRU-specific SRS subframes that start a number of WTRU-specific SRS subframes after a triggering subframe. For multiple SRS transmissions from multiple antennas, cyclic shift multiplexing and different transmission combs may be used. The cyclic shift for an antenna may be determined from a cyclic shift reference value. The cyclic shift determined for each antenna providing a maximum distance between cyclic shifts for the antennas transmitting SRS in a same WTRU-specific subframe. SRS transmissions from multiple antennas in the WTRU-specific subframe may be done in parallel. Methods for handling collisions between SRS and physical channels are presented.

    摘要: Methods and systems for transmitting uplink control information in an LTE Advanced system are disclosed. A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available (i.e., active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel.
