摘要： A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access network in the communication system, and passing the RAB to multiple digital filters to produce filtered RABs. The reverse link data rate is determined based on these filtered values of the RABs. From the filtered RAB values a continuous fluid power level is determined each rate update. The access terminal maps the continuous fluid power level to actual physical transmissions by dithering among discrete power levels allowed by the physical layer.

摘要： Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

摘要： Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.

摘要： In a wireless communications system, a serving base station performs outer and closed power control for an overhead channel and a traffic channel for data, either of which can carry an acknowledgement (Ack) channel and Channel Quality Indicator (CQI) channel on an uplink from User Equipment (UE). In an exemplary aspect, data packet communication is implemented in 3GPP LTE Rel. 8 wherein the uplink has a Single Carrier Frequency Division Multiplex (SC-FDM) uplink waveform. The UE performs open loop power control by a determining transmit power spectral density value by using received energy per symbol for a reference signal.
