Communication method and communication apparatus

A user equipment, comprising:

• at least one processor;
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• determine a quantity and a position of one or more control channel elements (CCEs) used by a control channel of the user equipment, wherein each of the one or more CCEs corresponds to a plurality of resource element groups (REGs), the plurality of REGs form at least one REG bundle, and any REG bundle in the at least one REG bundle comprises a plurality of resource blocks (RBs) that are consecutive or adjacent in at least one of time domain or frequency domain;
• and
• determine the at least one REG bundle from a control resource set based on at least one of a REG bundle size or a REG bundle pattern, wherein the control resource set comprises a RB set used to receive the control channel, the RB set comprises a plurality of RBs, each RB corresponds to one REG, and REGs corresponding to the control resource set are numbered in time-first manner;
• and
• a transceiver, the transceiver is configured to receive the control channel from a network device by using the one or more CCEs,
• wherein:
• the control resource set occupies one symbol in time domain, and any REG bundle in the at least one REG bundle occupies one symbol in time domain and six consecutive or adjacent REGs in frequency domain;
• the control resource set occupies two symbols in time domain, and any REG bundle in the at least one REG bundle occupies two consecutive or adjacent symbols in time domain and three consecutive or adjacent REGs in frequency domain;
• the control resource set occupies three symbols in time domain, and any REG bundle in the at least one REG bundle occupies three consecutive or adjacent symbols in time domain and one REG in frequency domain;
• or
• the control resource set occupies three symbols in time domain, and any REG bundle in the at least one REG bundle occupies three consecutive or adjacent symbols in time domain and two consecutive or adjacent REGs in frequency domain.

A communication method, comprising:
