1. An apparatus for a wireless communication system,
wherein the apparatus is configured to perform semi-persistent scheduling, SPS,
wherein a size of an SPS interval is based on one or more transmission time intervals,
wherein the apparatus is configured to receive and process a configuration message, the configuration message comprising one or more data fields indicative of the size of the SPS interval,
wherein the configuration message indicates several SPS configurations and the apparatus is configured to switch between the several SPS configurations, or selectively activate and deactivate one or more of the SPS configurations, subsequent to the configuration message and responsive to further configuration messages or control messages subsequent to the configuration message,
wherein the control message is a Downlink Control Information, DCI, and wherein the configuration message indicates several SPS configurations, the several SPS configurations being referenced by the DCI using a common SPS Radio Network Temporary Identifier, RNTI, the DCI comprising a SPS configuration index to discriminate between the several SPS configurations, the DCI causing a selective activation and deactivation of one of more of the several SPS configurations, and
wherein, after a valid activation of the one of more SPS configurations, the apparatus is configured to decode a physical downlink control channel, PDCCH, to obtain information regarding a change of one or more of the following: assigned resources, a transmission mode, a modulation and coding scheme, MCS.
