Abstract: A terminal (e.g. user equipment (UE)) receives signal sending indication information that is sent by an access network device for an uplink subframe, where the signal sending indication information is used to instruct the terminal to send a sounding reference signal SRS in a first symbol of the uplink subframe, and/or used to instruct the terminal to send a PUSCH in a symbol that is included in a second symbol set of the uplink subframe. The terminal sends an SRS and/or a PUSCH in the uplink subframe based on the signal sending indication information.

Abstract: A control information processing method, a base station, and a terminal are provided. A base station determines jointly encoded control information for an uplink subframe, where the jointly encoded control information is control information obtained by jointly encoding first control information and second control information; and the base station sends the jointly encoded control information. A terminal receives jointly encoded control information sent by a base station, where the jointly encoded control information is for an uplink subframe, and is control information obtained by jointly encoding first control information and second control information; and the terminal performs clear channel assessment CCA based on the jointly encoded control information, and occupies, after finishing the CCA, the uplink subframe to send a signal. According to the present invention, control signaling overheads can be reduced.
