Scheduled and autonomous transmission and acknowledgement
First Claim
1. A remote station, comprising:
- a data buffer for receiving data for transmission;
a message generator for generating an access request message when the data buffer contains data for transmission;
a receiver for receiving one or more individual grant channels and one or more common grant channels from a base station;
a message decoder for decoding an access grant directed to the remote station, the access grant comprising an individual grant directed on one of the one or more individual grant channels or a common grant on one of the one or more common grant channels; and
a transmitter for transmitting the access request message and for transmitting a portion of data from the data buffer in response to a decoded access grant, wherein the transmitter further transmits a limited portion of the data in the data buffer autonomously, irrespective of whether an access grant has been received.

Abstract
Techniques for efficient signaling to and from a plurality of mobile stations are disclosed. In one embodiment, a subset of mobile stations may be allocated a portion of the shared resource with one or more individual access grants, another subset may be allocated a portion of the shared resource with a single common grant, and yet another subset may be allowed to use a portion of the shared resource without any grant. In another embodiment, an acknowledge and continue command is used to extend all or a subset of the previous grants without the need for additional requests and grants, and their associated overhead. In one embodiment, a traffic to pilot ratio (T/P) is used to allocate a portion of the shared resource, allowing a mobile station flexibility in selecting its transmission format based on T/P.
