1. A method for use in a wireless communications network, comprising:
- sending, from a base station to a mobile station, at least one trigger parameter corresponding to a trigger condition, the at least one trigger parameter comprising at least one of a first parameter relating to power headroom increase at the mobile station, and a second parameter relating to power headroom decrease at the mobile station;
in response to occurrence of the trigger condition, receiving in a reverse wireless link, information relating to status of a buffer in the mobile station and receiving information relating to a data rate used by the mobile station when transmitting over the reverse wireless link.

11. An article comprising at least one storage medium containing instructions that when executed cause a mobile station in a wireless communications network to:
-
detect that a trigger condition has occurred, the trigger condition comprising one of a power headroom increase at the mobile station exceeding a first value, and a power headroom decrease at the mobile station exceeding a second value; send, in a reverse wireless link in response to detecting the trigger condition, a message having at least two fields that contain information indicative of a data rate for transmission by the mobile station in the reverse wireless link, the information based on at least one of buffer occupancy and power headroom. - View Dependent Claims (12, 13, 14, 15, 16, 22, 23)

17. A mobile station comprising:
-
an interface to communicate with a base station over a wireless link; a buffer to store data for communication over the wireless link to the base station; and a controller to send information relating to a status of the buffer and information relating to a data rate over the wireless link to the base station in response to a trigger condition, the trigger condition comprising a current power headroom differing from a previous power headroom by more than a predetermined amount. - View Dependent Claims (18, 19, 20, 24)
