Uplink scheduling and resource allocation with fast indication
First Claim
1. A method in a wireless terminal in a Long Term Evolution (LTE) system, comprising:
- sending a layer 1 indication using an uplink transmission resource, wherein the uplink transmission resource is pre-allocated for a particular wireless terminal; and
repeating the layer 1 indication for at least one time, using the pre-allocated uplink transmission resource,wherein transmissions occur on the pre-allocated uplink transmission resource only when the particular wireless terminal is sending a layer 1 indication on the uplink transmission resource.

Abstract
Systems and methods for signalling transitions between talk-spurt state and silence state for wireless terminals having semi-persistently allocated uplink resources are employed. A layer ½ indication of the state transitions may be transmitted using a resource that is specifically allocated for that purpose. Alternatively, ACK/NACK signalling may be employed. Layer 1 indications may be employed for both state transition types. Alternatively, in-band MAC layer signalling may be used to signal state transition from talk-spurt state to silence, or the network may deduce this state transition on its own. A different uplink wireless transition resource is allocated for the talk-spurt state vs. the silence state.
