Detecting a control channel in a search space
摘要
說明書
Correspondingly, the terminal device may obtain a resource of each candidate control channel in the search space set based on the configuration information of the search space set.
Optionally, a CCE included in a candidate control channel in each search space set may be determined based on a quantity of CCEs in a control-resource set associated with the search space set, an aggregation level corresponding to the search space set, and a quantity of candidate control channels included at the aggregation level.
For example, the search space set 1 is associated with the control-resource set 1, a quantity NCCE of CCEs included in the control-resource set 1 is 16, and the 16 CCEs are respectively denoted as a CCE 0, a CCE 1, a CCE 2, a CCE 3, a CCE 4, a CCE 5, a CCE 6, a CCE 7, a CCE 8, a CCE 9, a CCE 10, a CCE 11, a CCE 12, a CCE 13, a CCE 14, and a CCE 15.
In addition, the search space set includes two search spaces, and aggregation levels are respectively 1 and 2, where the search space whose aggregation level is 1 includes four candidate control channels, and the search space whose aggregation level is 2 includes two candidate control channels. It is assumed that a CCE included in a candidate control channel m whose aggregation level is L meets the following formula: L{(Y+└m·NCCE/(L·MmaxL)┘+n)mod └NCCE/L┘}+i
