A wireless telecommunications network supplies a semi-persistent resource that a wireless station (30) can use for special purposes such as a retransmission of packets for ARQ purposes or a control signal. The semi-persistent resource can be allocated by the system to other terminals if, e.g., a retransmission is not required. Since a retransmission is generally performed in response to a NACK received from a base station (28), the NACK may itself serve as a token that permits the wireless station (30) to use the semi-persistent allocation. Thus, the technology includes, e.g., a method for resource allocation on a semi-persistent basis and efficient signaling for the usage of such allocation. |
