determining a quantity of candidates comprised in each aggregation level in each set of resources according to the quantity of candidates in each set of resources comprised in the notification and a first preset rule.
5 . The method according to claim 1 , wherein the determining the quantity of candidates for transmitting a downlink control channel, of the at least one set of resources for transmitting a downlink control channel further comprises:
determining the quantity of candidates in the at least one set of resources according to a second preset rule.
6 . A method for transmitting a downlink control channel, the method comprising:
determining a quantity of downlink control channel candidates in at least one set of resources for transmitting a downlink control channel; and sending a notification of the quantity of downlink control channel candidates in the at least one set of resources to a terminal by explicit signaling, or implicitly indicating the quantity of downlink control channel candidates in the set of resources according to a predefined rule; and
sending a downlink control channel within the at least one set of resources.
7 . The method according to claim 6 , wherein the notification comprises at least one of following information:
a quantity of candidates in each set of resources;
a quantity of candidates comprised in each aggregation level in each set of resources; or
aggregation levels supported in each set of resources, and a quantity of candidates included in each supported aggregation level.
