Abstract: A wireless hybrid (TDMA/CDMA) user equipment is disclosed. The user equipment receives and recovers signaled information of code and timeslot assignments of the user equipment to support a radio frequency communication. From the signaling information, an identifier of a plurality of assigned timeslots and an indication of a first and last code of a set of consecutive codes are recovered. The last code is identified by an identifier associated with the last code, and the same set of consecutive codes is assigned to each of the plurality of assigned timeslots.

Abstract: A base station, comprising a first channelization device to receive data and spread the data with a first channelization code to produce a first spread data field; a second channelization device to receive the same data as the first channelization device and spread the received data with a second channelization code that is different from the first channelization code to produce a second spread data field; a first training sequence device in communication with the first channelization device, the first training sequence device to combine the first spread data field with a first midamble to produce a first communication burst, the first midamble for estimating a channel impulse response; a second training sequence device in communication with the second channelization device, the second training sequence device to combine the second spread data field with a second midamble to produce a second communication burst, the second midamble for estimating a channel impulse response; a first scrambling device to scramble the first spread data field by a scrambling code associated with the base station; a second scrambling device to scramble the second spread data field by the scrambling code associated with the base station; a first diversity antenna to transmit the first communication burst; and a second diversity antenna to transmit the second communication burst.

Abstract: A plurality of signals are received in a shared spectrum. Samples of the received user signals are produced as a received vector. The received vector is segmented into a plurality of segments. For each segment, successively determining symbols for each user or group of signals (the group of signals having similar received power) by determining symbols for one user/group and removing a contribution of that one user/group from the received vector. The determined symbols corresponding to each segment are assembled into a data vector.

Abstract: A plurality of transmitted data signals are received at a receiver. The receiver measures a channel response associated with the transmitted data signals. A system response is determined. The system response is expanded to be piecewise orthogonal. The received data signals data is retrieved based on in part the expanded system response.

Abstract: Outer loop/weighted open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. A first communication station (110) transmits a communication to a second communication station including target adjustment information generated at the first station on the basis of measured error rates of communications from the second station to the first station. The second station receives the communication and measures 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 second station to the first station is based on in part weighting the path loss estimate in response to the estimate's quality and based on the receive target adjusted by the target adjustment information transmitted from the first station.

Abstract: A wireless time division duplex communication system using code division multiple access has a base station and user equipments. The system communicates using communication bursts (16). Each communication burst has a unique channelization code and a midamble code (20). Each midamble code is mapped to a set of at least one channelization code. For each communication burst to be transmitted in a time slot from the base station, the midamble code mapped to that burst's channelization code is determined. Communication bursts are generated and transmitted in the time slot. Each burst has the determined midamble code for its channelization code. The user equipment receives the bursts and determines each received midamble code. The user equipment determines the channelization codes of the transmitted communication bursts based on in part a result of the determining of each received midamble code.

Abstract: Un método y un aparato para senalizacion de informacion indicando los requerimientos de performance a los que una WTRU se acomete a satisfacer desde la WTRU para permitir una más eficiente asignacion de recursos de radio e incrementar la capacidad de la red. La WTRU puede senalizar informacion a la estacion base que incluye los requerimientos de performance que la WTRU se acomete a satisfacer, lo que incluye un codigo o un campo asociado con al menos un requerimiento de performance. En otra incorporacion, la informacion senalizada indica un cambio en los requerimientos de performance acometidos por a WTRU. En otra incorporacion más, la WTRU senaliza mediciones de calidad de canal, tales como mensajes de reportes de indicador de calidad de canal (CQI) a la estacion base, la cual, en turno, infiere cierta informacion referente al performance del receptor con base en las mediciones de calidad de canal.
