Abstract: Disclosed are a method for sending control information, a base station, and a user equipment (UE). Taking implementation of the method as an example, the method comprises: a base station determining a first subframe and a second subframe, wherein the first subframe is a subframe having a control region, and the second subframe is a subframe with no control region; and the base station sending control information to a UE in the control region of the first subframe, and sending a data signal and/or an enhanced physical downlink control channel (ePDCCH) on the second subframe to the UE. By means of this solution, the first subframe has a control region, the second subframe does not have a control region, and not all the subframes have a control region; therefore, the system overhead is reduced.

Abstract: Embodiments of the present disclosure provide a backoff window adjustment method, and an apparatus. In downlink transmission, a base station obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the base station on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel. In uplink transmission, a user equipment (UE) obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the UE on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel.

Abstract: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

Abstract: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.
