    摘要: Techniques for addressing high interference observed by a receiver in a wireless communication system are disclosed. The receiver may observe different interference power levels across a transmission symbol. In an aspect, the receiver applies different weights to different portions of the transmission symbol to account for fluctuation of interference power across the transmission symbol. In another aspect, a transmitter may send a transmission symbol such that a receiver can ignore a portion of a symbol period with high interference. In one design, the transmitter generates a transmission symbol including at least two copies of a signal component. The transmitter transmits at least one copy of the signal component in a portion of the symbol period in which the receiver does not observe high interference. The receiver processes the at least one copy of the signal component to recover data sent in the transmission symbol.

    摘要: A method for discontinuous transmission (DTX) signaling in a physical uplink shared channel (PUSCH) of a wireless communication system includes puncturing at least a portion of a physical uplink shared channel (PUSCH) at a location that would collide with acknowledgement (ACK)/negative (ACK/NACK) feedback if ACK/NACK feedback is transmitted. The method also includes transmitting DTX symbols in the punctured portion of the PUSCH by a user equipment (UE). The method further includes detecting DTX symbols on the PUSCH by an evolved Node B (eNodeB), indicating the UE is operating according to a DTX signaling mode.

    摘要: Techniques for reporting channel quality information (CQI) in a multi-carrier wireless communication system are disclosed. In one aspect, a user equipment determines one or more reporting groups, each comprising a plurality of component carriers which are configured for the user equipment. The user equipment may detect a trigger from a base station that selects a reporting group and may respond to the trigger by sending CQI for at least the activated component carriers in the selected reporting group.

    摘要: Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier. The UE may monitor for the first DCI format(s) on the first carrier to detect DCI sent to the UE. The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.

    摘要: Certain aspects of the present disclosure relate to techniques for user-specific search space design for multi-carrier operation in Long Term Evolution Advanced (LTE-A) systems. The user-specific search space can be designed for searching Physical Downlink Control Channels (PDCCHs) transmitted on one component carrier (CC) that schedules Physical Downlink Shared Channel/Physical Uplink Shared Channel (PDSCH/PUSCH) transmissions on two or more different CCs. In one aspect, multiple independent user-specific search spaces can be designed. In another aspect, one user-specific search space can be randomly derived and then expanded to accommodate search for multiple CCs. In yet another aspect, the search space design can retain randomness in starting search element indices of multiple PDSCH/PUSCH CCs, while overlapping of search spaces for multiple PDSCH/PUSCH CCs can be avoided.
