Communication method and apparatus

An apparatus, comprising:

• a memory storing instructions;
• and
• at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
• receiving configuration information from a network device, the configuration information indicating a first time-frequency resource, and the first time-frequency resource cannot be used to transmit a downlink data channel;
• determining that the first time-frequency resource belongs to a first-type time-frequency resource or a second-type time-frequency resource;
• and
• if the first time-frequency resource belongs to the first-type time-frequency resource, determining not to monitor a downlink control channel candidate, or determining that a downlink control channel detected on a downlink control channel candidate is invalid, the downlink control channel candidate overlapping the first time-frequency resource;
• or
• if the first time-frequency resource belongs to the second-type time-frequency resource, monitoring at least one downlink control channel candidate, or determining that a downlink control channel detected on the at least one downlink control channel candidate is valid, the at least one downlink control channel candidate overlapping the first time-frequency resource.

A non-transitory computer readable media storing computer instructions that configure at least one processor, upon execution of the instructions, to perform the following steps:

• receiving configuration information from a network device, the configuration information indicating a first time-frequency resource, and the first time-frequency resource cannot be used to transmit a downlink data channel;
• determining that the first time-frequency resource belongs to a first-type time-frequency resource or a second-type time-frequency resource;
• and
• if the first time-frequency resource belongs to the first-type time-frequency resource, determining not to monitor a downlink control channel candidate, or determining that a downlink control channel detected on a downlink control channel candidate is invalid, the downlink control channel candidate overlapping the first time-frequency resource;
• or
• if the first time-frequency resource belongs to the second-type time-frequency resource, monitoring at least one downlink control channel candidate, or determining that a downlink control channel detected on the at least one downlink control channel candidate is valid, the at least one downlink control channel candidate overlapping the first time-frequency resource.
