摘要： A method and apparatus for transmitting a burst of data over a supplemental channel on just one leg of a handoff by changing the maximum allowed burst duration of the data to be transmitted over the supplemental channel as a function of the future and/or current characteristics of the communication link of the leg(s) of the handoff. The data is then transmitted over just one leg of handoff using the maximum allowed burst duration. By changing the parameters of the data, the data may still be acceptably received at the mobile terminal over just one leg of the soft handoff even when the strength of the pilot signal used for the supplemental channel changes significantly. In an illustrative embodiment of the invention the stability of the communication link is used as a way of ascertaining the future conditions of the communications link.

摘要： A system and method for communicating between nodes in a communications network. The network includes nodes that broadcast and receive data packets over a radio channel. The system includes a distributed trunking method that distributes the communications between the nodes over multiple channels. Voice and other data may be broadcast over data channels, while information regarding the availability of the data channels is broadcast over a control channel. Access to the control channel is controlled using a protocol that may include carrier sense multiple access with collision avoidance (CSMA/CA), time division multiple access (TDMA) or a hybrid of CSMA/TDMA.

摘要： Resource allocation in a wireless data system determines a load condition of the system and adapts a target quality of service (QoS) characteristic, accordingly. Data transmission parameters may be assigned, or adapted, for the wireless units based on the adapted target QoS characteristics. Resources are allocated to data transmissions between wireless units based on these parameters. As the system load decreases, the target QoS characteristic is adapted so that more resources will be allocated to the wireless unit, and the QoS will improve. The adapted QoS threshold may be a data error rate or target fill efficiency for each wireless unit.

摘要： A method of applying one of several resource distribution algorithms to an incoming call to a communication system. The applied resource distribution algorithm is based on resource parameters obtained from a main scheduler of the communication system. Some of the resource parameters include the type of call, the resource usage and the resource allocation scheme. The resource parameters generally describe the amount of resources that are currently being used by the system and which resources are available to the incoming call. The method of the present invention admits the incoming call to the communication system in accordance with one of the resource distribution allocation schemes. In this manner, the resources of the communication system can be efficiently and fairly distributed to different types of users requesting admission to the communication system.

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： A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.

摘要： A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when Eb/No measurements for served mobiles do not meet target Eb/No levels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target Eb/No levels in a centralized manner based on an overall system state so that only a limited number of target Eb/No levels are allowed to increase when frame erasures occur. By preventing a percentage of target Eb/No level increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.
