Abstract
A method for reusing control channel resources in a wireless system includes selecting a subset of control channel resources from a specified set of control channel resources in a search space of the wireless system. The subset is smaller than the set. In addition, the method includes transmitting a first control channel using only the subset of control channel resources. Further, the method includes selecting at least one of the control channel resources not transmitted in the first control channel. Furthermore, the method includes transmitting a different control channel using at least one of the control channel resources specified for but not scheduled in the first control channel.
Claims51
A method for reusing control channel resources in a wireless system, comprising:
- selecting a set of control channel resources from available control channel resources in a search space of the wireless system, the set of control channel resources being selected to transmit a first control channel, and the set of control channel resources being based at least in part on an aggregation size;
- transmitting a first control channel using only a first subset of the set of control channel resources, the first subset being less than the set;
- selecting a second subset from the set of control channel resources, the second subset not being used for transmitting the first control channel;
- and
- transmitting a second control channel using the second subset, the first control channel being different from the second control channel.

A method for reusing control channel resources in a wireless system, comprising:
- receiving an indication of a first subset of control channel resources for a first control channel and a second subset of control channel resources for a second control channel to be transmitted in a search space for the wireless system,
- the first subset and the second subset being selected from a set of control channel resources allocated to the first control channel, the first subset being less than a set of control channel resources, the set of control channel resources being based at least in part on an aggregation size,
- the second subset selected from the set of control channel resources for the transmission of the second control channel is different from the first subset of control channel resources for the transmission of the first control channel, the second subset not being used for transmitting the first control channel;
- and
- decoding the first control channel transmitted with the first subset of control channel resources, the first control channel being decoded in accordance with the indication.
