Abstract:
1. A method of releasing at least one persistent resource, the method comprising: receiving a physical downlink control channel (PDCCH) transmission, wherein a field from the PDCCH transmission is indicative of whether a persistent resource release is applicable to a downlink (DL) persistent resource or an uplink (UL) persistent resource; determining whether to explicitly or implicitly acknowledge the persistent resource release based on whether the persistent resource release is applicable to the DL persistent resource or the UL persistent resource; and transmitting a positive acknowledgement (ACK) which denotes that PDCCH transmission has been received on condition that the persistent resource release is applicable to the DL persistent resource and refraining from transmitting the positive ACK on condition that the persistent resource release is applicable to the UL persistent resource.
