Abstract
It is provided an apparatus, including observing means configured to observe a first parameter; deciding means configured to decide, based on the first parameter, whether or not an original search space of a downlink control channel of an orthogonal frequency division multiplex technology is to be redefined; and redefining means configured to redefine the original search space, thus obtaining a redefined search space.
Claims20
An apparatus comprising:
- one or more processors;
- and
- one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the apparatus to perform at least the following:
- monitoring a first parameter comprising an information when an original search space of a downlink control channel of an orthogonal frequency division multiplex technology is redefined;
- checking whether or not the first parameter indicates the original search space is redefined;
- and
- searching an entry at a search entry of the redefined search space.
A method comprising:
- monitoring a first parameter comprising an information when an original search space of a downlink control channel of an orthogonal frequency division multiplex technology is redefined;
- checking whether or not the first parameter indicates that the original search space is redefined;
- and
- searching an entry at a search entry of the redefined search space if the checking means checks that the original search space is redefined.
A computer program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising code for performing at least the following:
- monitoring a first parameter comprising an information when an original search space of a downlink control channel of an orthogonal frequency division multiplex technology is redefined;
- checking whether or not the first parameter indicates that the original search space is redefined;
- and
- searching an entry at a search entry of the redefined search space if the checking means checks that the original search space is redefined.
