    摘要: Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

    摘要: Techniques for handling inconsistent control information in a wireless communication system are described. In an aspect, inconsistent control information is handled in different manners for the downlink and uplink. In one design, a user equipment (UE) receives a first grant with first control information for a first data transmission and also receives a second grant with second control information for a second data transmission. The UE determines that the second control information is inconsistent with the first control information, e.g., due to the two grants conveying different transport block sizes. The UE determines whether to retain or discard the second grant based on whether the two grants are for data transmissions on the downlink or uplink. In one design, the UE retains the second grant if the two grants are for data transmissions on the downlink and discards the second grant if the two grants are for data transmissions on the uplink.

    摘要: Systems and methodologies are described that facilitate detecting cell interference and/or loading by analyzing control data transmitted between devices communicating in the cell. Control data resources can be transmitted related to communication received over data channels, and the control data resources can comprise quality indicators related to the data as well as resource identifiers that specify a resource over the data channel related to the data. Multiple control data resources can be transmitted per communication specifying a beginning and ending resource identifier of related data channel resources. If this control data is decodable at a wireless device, the associated resources corresponding to the resource identifiers can be marked as interfered and/or avoided in subsequent communication or resource allocation requests by the wireless device.

    摘要: Systems and methodologies are described that facilitate transmitting and receiving signals over I and Q branches of a communication channel to mitigate potential I/Q imbalance. In particular, a device can transmit a signal over the I and Q branches to distribute transmission power substantially evenly for a given channel. The device can demodulate the data with a code or matrix having real and complex modifiers resulting in an I and Q branch signal for transmission. Where the channel has multiple resources, the device can alternate or transmit over the I branch in one resource and the Q branch in another resource for a given signal to distribute power. Also, the device can apply a complex scrambling code to distribute a signal over both the I and Q branches. The device can also use QPSK or higher order modulation to send the signals meant for the same user.

    摘要: Certain aspects of the present disclosure relate to a method for sending control information to multiple user terminals that share the same resources in a Spatial Division Multiple Access (SDMA) wireless system. The control information can be transmitted from an access point over a physical downlink control channel (PDCCH) that is common for a plurality of user terminals. The overall PDCCH overhead can thus be reduced due to a smaller number of required PDCCH in the SDMA wireless system.

    摘要: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.
