摘要： The present invention is a method for selectively providing, on demand, a Quality of Service level to an end user's data transmitted from a base station to a mobile station of a High Data Rate system. In the disclosed method, a data base is established which contains the Quality of Service level selected by a mobile user from a plurality of levels for data to be transmitted from the base station to the mobile station. Using the reverse link, an end user at a mobile notifies the base station that it is ready to receive data and specifies the rate at which the data is to be sent. Upon receipt of the request for data from the mobile terminal, the base station accesses and runs a scheduler which determines which user's data is to be transmitted next. For each end user, the scheduler divides the requested data rate by the average rate of data received by the mobile during a specific interval and then combines by adding or multiplying the result with the Quality of Service level requested by the end user for data. The end user that has the greatest final result is normally selected to next receive data. The scheduler then conditions the base station to transmit data to the identified mobile station at the requested rate and selected Quality of Service level.

摘要： A method for determining the reverse link data Rate Limit for mobile stations active on the reverse link of a High Data Rate system is disclosed. In the ideal case, the Rate Limit is based on only the number of mobile stations located in a common sector that are actually active on the reverse link. Currently, the Rate Limit is determined from the total number of mobile stations in a common sector where the total includes mobiles that are transmitting and receiving. Thus, the current method includes mobile stations that are active on the forward link and may not be active on the reverse link. In this invention, a more optimum method of estimating the reverse link loading is obtained from calculations which includes only the mobile stations which are active on the reverse link. An estimate of the reverse link loading of the mobile stations in a common cell is obtained by adding together the data rates of the data sent from each mobile in a common sector during a common frame. This aggregate rate of data during the frame is filtered to minimize irregularities by using the moving average of an infinite impulse response filter and then normalized. The normalized result is a percentage of the maximum achievable aggregate reverse link rate. The final result is compared with a set of threshold values to obtain the maximum Rate Limit that is then set for each mobile station.

摘要： The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.

摘要： A method of wireless communication over the reverse link. The method may include evaluating a reverse link loading. This evaluation step may involve examining at least two resources associated with reverse link loading within a first time period. Thereafter, a message is broadcast containing information regarding the availability of resources. This message is generated in response to the evaluated reverse link loading. This availability of resources message may correspond with an overload condition, increasing a number of active connections, decreasing the number of active connections, increasing an available transmit rate, maintaining the available transmit rate and/or decreasing the available transmit rate. In one example, the availability of resources message comprises a reverse activity bit.

摘要： A resource allocation method equalizes distribution of network resources among gateway users connected to at least one gateway access terminal and non-gateway users. Gateway access terminals having data backlogs exceeding a predetermined backlog threshold are assigned higher priorities to increase their transmission rate and relieve the backlog. Alternatively, priority is assigned based on the relative data backlogs of all of the gateway access terminals in the network. This ensures that gateway users are allocated resources fairly and in a comparable manner to non-gateway users, maximizing system throughput.

摘要： A method of controlling the power in a wireless communication system. In one embodiment of the invention, a base station determines the information rate of a signal to be transmitted to a mobile station, and obtains the variable power control scaling factor based on this information rate. The base station then transmits the variable power control scaling factor to the mobile station. The mobile station determines a target signal quality measurement for a received signal from the base station, such as a target Eb/N0, and scales the target Eb/N0 by the variable power control scaling factor. The mobile station also obtains an information rate scaling factor based on the information rate of the received signal, and further scales the target Eb/N0 by this information rate scaling factor. The mobile station then compares the target Eb/N0 to a measured Eb/N0 of the received signal. An increase in power of the received signal is requested when the measured Eb/N0 of the received signal is smaller than the scaled Eb/N0. A decrease in power of the received signal is requested when the measured Eb/N0 of the received signal is larger than the scaled Eb/N0. Providing the variable power control scaling factor to the mobile station allows frames having an information rate lower than the full rate to be transmitted at a power even lower than the power of a frame having an information rate equal to the full rate times the information scaling factor.
