Abstract
A semi-persistent resource scheduling (SPS) allocation of a user equipment is deactivated in an LTE-based mobile communication system without requiring changes to the Physical layer-to-MAC layer interface and/or changes to PDCCH formats agreed by the 3GPP. A combination of NDI value and MCS index is defined that commands release of SPS resources. An alternative solution proposed defines a special transport block size that when signaled in a PDCCH commands release of SPS resources.
Claims20
A method for releasing a semi-persistent scheduled (SPS) resource allocation in a mobile communication system, wherein a user equipment performs the steps of:
- receiving control signaling via a physical downlink control channel (PDCCH), and
- releasing the semi-persistent scheduled resource allocation when a set of conditions is met including when a modulation coding scheme index in the received control signaling includes an index in a predetermined subset of the set of modulation coding scheme indices,
- wherein the predetermined subset of the set of modulation coding scheme indices have indices with undefined or reserved representations of transport block size.
A user equipment for a mobile communication system, comprising:
- a receiver configured to receive control signaling via a physical downlink control channel (PDCCH), and
- processing circuitry configured to release a semi-persistent scheduled (SPS) resource allocation when a set of conditions is met including when a modulation coding scheme index in the received control signaling includes an index in a predetermined subset of the set of modulation coding scheme indices,
- wherein the predetermined subset of the set of modulation coding scheme indices have indices with undefined or reserved representations of transport block size.
