摘要： Techniques for efficiently multiplexing a reference signal and data on different sets of subcarriers in the same symbol period are described. In one design, a user equipment (UE) performs a discrete Fourier transform (DFT) on a set of modulation symbols for data to obtain data symbols. The UE also obtains reference symbols generated based on a reference signal sequence corresponding to a cyclic shift of a base sequence. The UE maps the reference symbols to a first set of subcarriers and maps the data symbols to a second set of subcarriers. The UE then generates a transmission symbol based on the mapped reference symbols and the mapped data symbols. The UE may also transmit reference signals and data (i) in multiple symbol periods of a slot or a subframe and/or (ii) from multiple antennas using frequency division multiplexing (FDM) or code division multiplexing (CDM).

摘要： Methods, systems, apparatus and computer program products are provided to facilitate power control in wireless communication systems. A cell that is experiencing excessive interference conditions may generate an over-the-air overload indicator indicative of interference conditions at the cell. The over-the-air overload indicator is received by one or more user equipment in a neighboring cell. In response, the user equipment determines adjustments to its transmit power that reduce and/or eliminate the interference. This determination may be carried out by the user equipment, by the serving base station, or through cooperation between the user equipment and the serving base station. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

摘要： Systems and methodologies are described herein that facilitate improved modulation and coding techniques for a multiple-in multiple-out (MIMO) communication system. As described herein, data to be transmitted over a set of physical layers (e.g., corresponding to antennas, beams, etc.) can be processed such that encoding is performed on a per-codeword basis and modulation is performed on a per-layer basis, thereby mitigating performance degradation experienced by traditional systems due to layer imbalance. As further described herein, per-codeword code rate parameters and per-layer modulation parameters can be signaled to a device in various manners, such as through modulation and coding scheme (MCS) signaling, explicit code rate and/or modulation scheme signaling, relative code rate and/or modulation scheme signaling, or the like.

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： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.
