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： Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.
摘要翻译：可以基于TDD配置中的特殊子帧配置允许下行链路传输来分配用于确认（ACK）和/或否定确认（NAK）的比特。对于载波聚合，ACK / NAK比特可以仅分配给允许下行链路传输的分量载波（CC）中的特殊子帧。此外，例如，如果单个CC被配置为允许在其特殊子帧之一上的下行链路传输，则可以将ACK / NAK比特分配给所有CC特殊子帧。 ACK / NAK位也可以分配给所有特殊子帧。

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 performing interference and power control in a wireless communication system are described. An asymmetric power control scheme adjusts the transmit power of a user equipment (UE) in an asymmetric manner, e.g., with different up and down step sizes. In one design, a parameter value may be determined based on received SINR of at least one Node B. Up and down steps may be determined based on the parameter value and may have different sizes. At least one overloading indicator from at least one neighbor Node B may be obtained. The transmit power of the UE may be adjusted based on the up and down steps and the at least one overloading indicator. For example, the transmit power may be increased by the up step if an overloading indicator from the strongest neighbor Node B is not received and may be decreased by the down step otherwise.

摘要： A user equipment (UE) is configured for carrier aggregation in a wireless communication system. The UE selects control information to be transmitted in an uplink control channel format in a component carrier of two or more component carriers, where the control information includes information types associated with different information reliability requirements. The UE generates an open-loop power control parameter and/or a closed-loop power control parameter based on the information types. The UE transmits the control information in the uplink control channel format at a power level determined by the open-loop power control parameter and/or the closed-loop power control parameter.
