摘要:
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 1/2 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.
