Scheduling enhancements for latency-constrained and reliable wireless communication systems

A method, comprising:

• performing semi-persistent scheduling so as to receive or transmit data in a wireless communication system,
• wherein a size of an SPA interval is based on one or more transmission time intervals,
• wherein the method comprises receiving and processing 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, and
• 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.

A non-transitory digital storage medium having a computer program stored thereon to perform the method, comprising:

• performing semi-persistent scheduling so as to receive or transmit data in a wireless communication system,
• wherein a size of an SPA interval is based on one or more transmission time intervals,
• wherein the method comprises receiving and processing 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, and
• 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,
• when said computer program is run by a computer.
