Abstract: Data is to be transmitted from one transmitting point to multiple reception points in a wireless communication system. A transmitting antenna array has multiple antenna elements at the one transmitting point. Channel information is measured for each antenna element at each reception point. Antenna adjustments are determined using the measured channel information. The measured channel information from all of the users is correlated to determine weighting factors for each antenna element. The weighting factors to a point to multiple point transmission are applied prior to being radiated by each antenna element.

Abstract: Data is transferred in a wireless communication system, such as a wireless spread spectrum communication system. Data is encoded to produce a plurality of data streams. For each of a plurality of transmitting antennas, the data streams are used to produce a vector for transmission. Each transmission vector is transmitted by its transmitting antenna through a wireless air interface experiencing multipath. Multipath components from each transmitted transmission vector are received by a plurality of receiving antennas. The received multiplath components are equalized to recover the transmission vectors. The data is recovered from the recovered transmission vectors.

Abstract: The present invention is a user equipment (UE) which receives a communication signal over a physical reference channel using a reference channel receiver. An expected path loss is calculated using a path loss calculation device in response to the received communication signal. A signaling receiver receives an allocation of an uplink control channel including the amount of interference in the channel. Then, a power level calculation device, responsive to the path loss calculation device and the signaling receiver, determines an uplink power level based on the path loss and the interference level, whereby an uplink control channel transmission is initiated having the power level determined by the power level calculation device.

Abstract: A time division duplex using code division multiple access base station receives a plurality of data signals in a time slot. Each data signal experiences a similar channel response. The base station receives a combined signal over the shared spectrum in a time slot. The combined signal comprises the plurality of data signals. The combined signal is sampled at a multiple of a chip rate of the combined signal. The similar channel response is estimated. A channel response matrix or a channel correlation matrix is constructed based on in part the estimated channel response. A spread data vector is determined based on in part a fast fourier transform (FFT) decomposition of a circulant version of the channel response or channel correlation matrix. The spread data vector is despread to recover data from the matrix.

Abstract: The present invention is a method for transmitting a data field of symbols. A data field of symbols is generated and spread using a first channelization code, producing a first spread data field. The data field is again spread using a second channelization code, producing a second spread data field. Each of the channelization codes are uniquely associated with one of a first and second antenna. Then an RF signal including the first and second spread data fields is transmitted over the first and second antenna.

Abstract: A method of the employing weighted open loop power control in a user equipment (UE) is initiated by the UE receiving a communication and measuring its received power level. Based on, in part, the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communication from the UE is based, in part, on weighting the path loss estimate in response to the quality of the estimate.
