摘要： Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular, a single inner loop power control may be utilized to control a power of both a primary stream and a secondary stream, in a system where the power of the secondary stream is linked to the power of the primary stream. That is, a single transmit power control command calculated according to the primary stream and directly controlling the power of the primary stream can effectively control the power of both uplink streams. Further, the disclosure provides outer loop power control, where a signal-to-interference ratio target used in the inner loop power control can be adjusted. Here, the SIR target may be adjusted in accordance with at least one of a block error rate performance or a HARQ failure performance of one of the primary stream or the secondary stream.

摘要： Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular, scheduled uplink transmission power is allocated between a primary stream including an E-DPDCH and a secondary stream including an S-E-DPDCH. Specifically, a ratio between the power of the E-DPDCH and a primary pilot channel DPCCH, as well as a ratio between the power of the S-E-DPCCH and an unboosted power of the S-DPCCH, each corresponds to a first traffic to pilot power ratio. Further, the transport block size for a primary transport block provided on the E-DPDCH is determined based on the first traffic to pilot power ratio, while the transport block size for a secondary transport block provided on the S-E-DPDCH is determined based on a second traffic to pilot power ratio.

摘要： A base station receiver, a computer program product operable at a base station, and a method operable at a base station receiver, for receiving uplink transmit diversity transmissions utilizing a master/slave scheme at the receiver. One or more tracking loops, such as a searcher task, a time tracking loop, or a frequency tracking loop may be implemented at the base station receiver to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a first received pilot channel transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel transmitted utilizing an precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the first pilot channel.

摘要： An apparatus, method, and computer program product operable to determine a phase of a beamforming weight vector utilizing a memory of a previously used phase for the beamforming weight vector, capable of improving a channel estimate. A base station transmits a beamforming weight vector to a user equipment based on a determined channel estimate. The user equipment selects between the received beamforming weight vector, or a modified beamforming weight vector having its phase shifted by −360°, in accordance with a suitable selection criteria. That is, the selection is made such that a difference between the phase of the selected beamforming vector and a phase of a prior beamforming vector is within a predetermined range.

摘要： A wireless communication system transmits in a High Speed Downlink Packet Access (HSDPA) by having a Radio Network Controller (RNC) assign portions of data to a first serving cell and a second serving cell for transmitting to a user equipment. The first serving cell transmits data on a first downlink carrier to the user equipment. The second serving cell, which is independent from the first serving cell, transmits data on a second downlink carrier to the user equipment. In an optional aspect, the RNC receives a measurement report from the user equipment on a first uplink carrier via at least one of the first serving cell and the second serving cell.

摘要： A method, apparatus, processing system, and computer program product enable association of mis-aligned subframes from a first and second downlink with one another, such that a HARQ acknowledgment message including jointly encoded feedback for the respective subframes can be correctly interpreted by the corresponding cells. Here, an RNC may provide an RRC message to the UE to associate particular subframes with one another. Further, the RNC may provide NBAP messages to the cells transmitting the downlink signals, so that the cells can associate the HARQ acknowledgment message with the appropriate subframe. Still further, additional signaling provides for changing the set of associated subframes when needed due to a drift in the timing offset between cells.

摘要： Various processing options and systems are provided for setting/controlling feedback indicators referred to as “Happy Bits” in a wireless communication network using multiple uplink carriers. In one aspect, a Happy Bit is determined independently for each one of a plurality of uplink carriers based on channel conditions and buffer lengths for the respective carrier. For example, if a UE is transmitting the maximum data allowed by its serving grant for that carrier, the UE has available power to increase the data rate on that carrier, and the TEBS delay is greater than a certain threshold, then the Happy Bit for that carrier may be set to Unhappy to inform the Node B that the UE is capable of transmitting at a higher data rate on that carrier.
