摘要： Multiple transmit antenna transmission together with preferably pseudo-random, antenna-specific, scrambling (PRAS) is utilized to scramble incoming data differently on different antennas for those users requiring frequency diversity type transmissions. When PRAS is activated for a particular allocation, each transmit antenna applies a different scrambling sequence to the data symbols that are transmitted in the allocation.

摘要： A method and device in a communication system including a receiver having a plurality of receiving antennas for receiving a plurality of information bursts transmitted by at least one transmitting user device where the information bursts contain a number of data symbols and a pilot symbol sequence of content known at both the transmitting user device and the receiver. The method provides for computing a channel transfer function between the transmitting user device at each of the plurality of receiving antennas, by computing a simulated received pilot signal for each receiving antenna, computing an error signal between the simulated received pilot signal and the received pilot symbol sequence, computing a channel modeling sequence, wherein the power of the error signal is minimized, and computing the channel transfer function by weighting predetermined basis functions by the channel modeling sequence.

摘要： A method (300, 400, 500, 600) of communicating with a subscriber station (102). Responsive to determining that a supplemental communication link with the subscriber station is desirable, at least a second access point (106, 108, 110, 112, 114, 116) can be identified to establish the supplemental communication link with the subscriber station. Information can be communicated to the second access point. The information can identify the subscriber station and a pilot zone in which downlink supplemental data is to be transmitted from the second access point to the subscriber station. Downlink supplemental data (150) also can be communicated to the second access point. The downlink supplemental data can improve integrity of data transmitted from a first access point (104) to the subscriber station when the downlink supplemental data is transmitted to the subscriber station from the second access point.

摘要： In a wireless communication system, a method and apparatus for closed loop transmission is disclosed. In accordance with the preferred embodiment of the present invention, a time frequency portion of an uplink frame is dynamically reserved as a sounding zone for uplink channel sounding. A first message is transmitted to a first subscriber station in a downlink frame assigning a time-frequency resource within the sounding zone, and a sounding waveform. Furthermore, a signal is received from the subscriber station within the assigned time-frequency resource, a partial channel response is determined from the received sounding signal, and the subsequent transmission to the subscriber station is tailored based on the at least partial channel response.

摘要： A method and apparatus for performing spatial-division multiple access within a communication system is provided herein. During operation, nodes will return null subspace information along with their channel subspace information. The null subspace is similar to the channel subspace except that the null subspace information directs a base station to the matrix in a predefined codebook that results in minimum power being received at the node. The null subspace for each node is taken into consideration when communicating with a particular node.
