Method and apparatus for allocating control channel candidates

A device, comprising a processor, configured to invoke a program stored in a non-transitory computer readable storage medium, wherein when the program runs, the device is configured to:

• obtain K sets of resources configured for transmitting a control channel, wherein each of the K sets of resources comprises at least one physical resource block pair, and wherein K is an integer greater than 0;
• and
• detect the control channel on at least one of determine control channel candidates allocation in the K sets,
• wherein the control channel candidates in the K sets of resources is determined based on aggregation levels supported by the control channel, a quantity of control channel candidates corresponding to each aggregation level, the K sets of resources for transmitting the control channel, and types of the K sets of resource,
• wherein the types of the K sets of resources comprise one or both of a type of localized transmission mode and a type of distributed transmission mode, and
• wherein a first quantity of sets with the type of localized transmission mode is KL, and a second quantity of sets with the type of distributed transmission mode is KD, and
• wherein KL+KD=K, and each of KL and KD is an integer greater than or equal to 0.

A non-transitory computer readable medium comprising a program, wherein when the program is executed by a processor, the following steps are performed:

• obtaining K sets of resources configured for transmitting a control channel, wherein each of the K sets of resources comprises at least one physical resource block pair, and K is an integer greater than 0;
• and
• detecting the control channel on at least one of control channel candidates in the K sets of resources,
• wherein the control channel candidates in the K sets of resources is determined based on aggregation levels supported by the control channel, a quantity of control channel candidates corresponding to each aggregation level, the K sets of resources for transmitting the control channel, and types of the K sets of resources,
• wherein the types of the K sets of resources comprise one or both of a type of localized transmission mode and a type of distributed transmission mode,
• wherein a first quantity of sets with the type of localized transmission mode is KL, and a second quantity of sets with the type of distributed transmission mode is KD, and
• wherein KL+KD=K, and each of KL and KD is an integer greater than or equal to 0.

• wherein the types of the K sets of resources comprise one or both of a type of localized transmission mode and a type of distributed transmission mode,
• wherein a first quantity of sets with the type of localized transmission mode is KL, and a second quantity of sets with the type of distributed transmission mode is KD, and
• wherein KL+KD=K, and each of KL and KD is an integer greater than or equal to 0.
