    摘要: Systems, methods, apparatuses, and computer program products are described for power headroom reporting. A mobile device may identify a transmit power associated with each of a number of independently power controlled channels on one or multiple carriers configured for use by the mobile device. The transmit power may relate to one channel that is an uplink control channel, and one or more additional channels that are uplink shared channels. The identified transmit power of one channel (e.g., the uplink control channel) may be a virtual transmit power, while other identified transmit powers may be measured transmit powers for actual transmissions. The identified transmit powers may be added up, and the power headroom available for the mobile device may be calculated using the accumulated transmit powers. The mobile device may transmit a power headroom report to a base station.

    摘要: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus maintains at least one PHR trigger for triggering communication of a PHR for a plurality of component carriers. In addition, the apparatus communicates the PHR for at least one of the component carriers upon the at least one PHR trigger being triggered. The communicated PHR may be an aggregated PHR that includes power headroom information on the PCC and activated SCCs. The communicated PHR may further include an index associating information in the PHR to a corresponding component carrier. The communicated PHR may further include information indicating use of a PUSCH reference for computing the PHR for the at least one of the component carriers on which there is no PUSCH transmission.

    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 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.
