Abstract: An information receiving method, an information sending method, and a device are provided. Under these methods, a timing adjustment amount can be determined by a first access network device. The timing adjustment amount is an adjustment amount between a first timing at which the first access network device sends a first downlink signal to a first terminal device on a first frequency band and a second timing at which the first access network device sends a second downlink signal to the first terminal device on a second frequency band. The first frequency band and the second frequency band are paired frequency bands. First indication information can be sent, by the first access network device, to the first terminal device. The first indication information indicates the timing adjustment amount.

Abstract: A method includes: sending, by a first terminal device, an HARQ-ACK to a network device based on received HARQ-ACK feedback indication information sent by the network device, where the HARQ-ACK feedback indication information is used to indicate a transmission time interval commonly occupied by at least one terminal device to feed back an HARQ-ACK and proprietary information about an HARQ-ACK fed back by each terminal device, and the at least one terminal device includes the first terminal device. In this technical solution, HARQ-ACK feedback indication information can indicate proprietary information about an HARQ-ACK fed back by a terminal device, thereby reducing a load of an uplink control channel when the terminal device feeds back the HARQ-ACK.

Abstract: The present invention discloses a downlink control information sending method and device, and a downlink control information receiving method and device. The sending method includes: sending, by a base station device, downlink control information DCI on a physical downlink control channel PDCCH of a downlink subframe, where the DCI is used to instruct user equipment UE to receive physical downlink shared channel PDSCH information in an uplink subframe; and sending the PDSCH information in the uplink subframe. In this way, the base station can effectively schedule an uplink subframe, and a purpose of transmitting a downlink service by using an uplink subframe is achieved, which not only improves utilization of a wireless spectrum resource corresponding to the uplink subframe, but also effectively diverts load pressure of a wireless spectrum resource corresponding to a downlink subframe. Therefore, overall utilization of wireless spectrum resources of a system is improved.

Abstract: Example random access methods and apparatus are described. In one example method, a terminal device receives a system message that is sent by a network device on a first downlink carrier. The system message includes first information for performing random access on a first uplink carrier and second information for performing random access on a second uplink carrier. A frequency of the first uplink carrier is higher than a frequency of the second uplink carrier, and a frequency of the first downlink carrier is the same as the frequency of the first uplink carrier. The terminal device sends a random access request message on the first uplink carrier or on the second uplink carrier, and receives a random access response message that is sent by the network device on the first downlink carrier.

Abstract: Embodiments can provide an information transmission method and an access network device. For achieving this, an indication message sent by a second access network device can be received by a first access network device in a first time segment of a first subframe. The indication message is configured to instruct the first access network device to communicate with the second access network device or with a terminal device in a target subframe. The target subframe can include at least one of the first subframe and a second subframe, and the first subframe precedes the second subframe. Communication can be performed, by the first access network device, with the second access network device or with the terminal device in the target subframe according to the indication message.
