A wireless communications network includes a base station to communicate with plural mobile stations over a wireless link. A broadcast message is sent to the plural mobile stations, with the broadcast message containing an indication for indicating to the plural mobile stations that the mobile stations are to change data rates for transmissions over a reverse wireless link.

Communicating a broadcast message to change data rates of mobile stations

A method for preventing the occurrence of overload conditions in a multi-carrier communication system such as, but not limited to, enhancements to 1xEV-DV by controlling the amount of voice and data users having access to the communication system in order to provide enhanced QoS and load balancing. The method includes converting one of carriers in the multi-carrier voice/data system to a voice-only carrier when loading exceeds a given threshold related to QoS and outage criteria.

Multi-carrier load balancing scheme for voice and data

A wireless communications network includes a mobile station and base station communicating an indicator of an autonomous data rate supportable over a reverse wireless link between the mobile station and base station. The mobile station and base station also communicate a flag indicating whether autonomous is enabled for the mobile station. In response to the flag indicating that autonomous mode is enabled, data is communicated, over the reverse wireless link, at a data rate less than or equal to the autonomous data rate without the base station having to first schedule the mobile station.

Autonomous mode transmission from a mobile station

A mobile station transmits sub-packets at a specified transmission rate or an autonomous transmission rate based on a PERSISTENCE bit. The mobile station increments, decrements, or does not change the transmission rate when the PERSISTENCE bit is a second logic state and a rate control bit (RCB) value is a first, a second, or a third value. Another embodiment of the present invention includes an ALL_ACID_IND bit that instructs the mobile station to adjust the specified transmission rate for either a single H-ARQ channel or for all H-ARQ channels. In an alternate embodiment, the mobile station uses the RCB in conjunction with a NAK to adjust a transmission-to-pilot ratio. After the NAK, the mobile station monitors the RCB value to increase the transmission rate, decrease the transmission rate, or not to change the transmission rate of subsequent sub-packets of the same data packet.

Reverse link enhancement for CDMA 2000 Release D

A wireless communications network includes a mobile station and base station that are capable of communicating over a wireless link. Information relating to a status of a buffer in the mobile station and information relating to a data rate over a reverse wireless links is communicated over the reverse wireless link.

Communicating in a reverse wireless link information relating to buffer status and data rate of a mobile station

A cellular communications system uses FCS (fast cell switching) for forward communications links, for communicating data from respective cells or sectors to a mobile terminal, in response to FCS requests by the terminal on a reverse communications link. An FCS rate, or rate of said requests, is varied in dependence upon a C/I reliability criterion, which represents a reliability with which C/I is determined and predicted by the mobile terminal, for example being either of two selected rates depending upon a comparison of the criterion with a threshold. The criterion can be, for example, a determined speed of the mobile terminal, or an averaged probability that a C/I prediction error is less than a predetermined amount.
