    摘要: Methods and apparatuses are provided for determining cyclic shift (CS) values and/or orthogonal cover codes (OCC) for a plurality of demodulation reference signals (DM-RS) transmitted over multiple layers in multiple-input multiple-output (MIMO) communications. A CS index can be received from a base station in downlink control information (DCI) or similar signaling. Based at least in part on the CS index, CS values for the plurality of DM-RSs can be determined. In addition, OCC can be explicitly signaled or similarly determined from the CS index and/or a configured CS value received from a higher layer. In addition, controlling assignment of CS indices and/or OCC can facilitate providing orthogonality for communications from paired devices in multiuser MIMO.

    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: 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.
