Control channel resource configuration method, base station, and terminal device

An apparatus, comprising:

• one or more processors, and
• one or more memories coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
• receiving, from a base station, higher layer signaling comprising indication information indicating a configuration of a control channel time-frequency resource unit, and the configuration is one of at least two-configurations of control channel time-frequency resource units;
• determining a time-frequency resource area based on the indication information;
• and
• detecting a first control channel in the time-frequency resource area, wherein
• the at least two configurations of control channel time-frequency resource units comprise a first configuration and a second configuration, wherein
• a control channel time-frequency resource unit of the first configuration occupies one orthogonal frequency division multiplexing symbol (OFDM) in a time domain and a reference signal for demodulating the first control channel with the first configuration is located on the one OFDM symbol under the first configuration, and wherein
• a control channel time-frequency resource unit of the second configuration occupies at least two OFDM symbols in the time domain and a reference signal for demodulating the first control channel with the second configuration is located on at least one of the at least two OFDM symbols under the second configuration.

A non-transitory computer-readable medium storing program instructions executable by at least one processor to perform operations comprising:

• receive, from a base station, higher layer signaling comprising indication information indicating a configuration of a control channel time-frequency resource unit, and the configuration is one of at least two-configurations of control channel time-frequency resource units;
• determine a time-frequency resource area based on the indication information;
• and
• detect a first control channel in the time-frequency resource area, wherein
• the at least two configurations of control channel time-frequency resource units comprise a first configuration and a second configuration, wherein
• a control channel time-frequency resource unit of the first configuration occupies one orthogonal frequency division multiplexing symbol (OFDM) in a time domain and a reference signal for demodulating the first control channel with the first configuration is located on the one OFDM symbol under the first configuration, and wherein
• a control channel time-frequency resource unit of the second configuration occupies at least two OFDM symbols in the time domain and a reference signal for demodulating the first control channel with the second configuration is located on at least one of the at least two OFDM symbols under the second configuration.
