Abstract: A random access method and apparatus to increase an opportunity of performing physical random access channel (PRACH) access, where the method includes receiving, by a terminal, information about a PRACH time window from a base station, where the information about the PRACH time window carries a size of the PRACH time window, preempting, by the terminal, an unlicensed carrier on which a PRACH resource is configured, and performing, by the terminal before the size of the PRACH time window is exceeded, .PRACH access on the successfully preempted unlicensed carrier on which the PRACH resource is configured. Therefore, by configuring the PRACH time window, the terminal has more opportunities to preempt the unlicensed carrier on which the PRACH resource is configured, greatly improving a PRACH access success rate.

Abstract: A multi-link configuration method, a base station, and a user equipment, where the UE generates uplink information and sends the uplink information to the base station. The base station configures a first set or a second set for the UE based on the uplink information. In this process, the transmission point included in the first set is a candidate transmission point, and the transmission point included in the second set establishes a plurality of links to a user, and is a transmission point that actually transmits data to the UE. When a signal of the transmission point included in the second set is weak or interrupted, a transmission point with good quality is selected from the first set and added to the second set to reduce a quantity of times of link interruption and service interruption.

Abstract: A method for determining a feedback resource in a sidelink includes a first terminal sending SCI to a second terminal, where the SCI includes indication information. The indication information is used to indicate a first resource or a first resource window to be occupied for sending hybrid automatic repeat request HARQ feedback information by the second terminal, and the first resource window includes a plurality of candidate first resources. The method further includes the first terminal receiving, on the first resource, the HARQ feedback information sent by the second terminal, or monitors, in the first resource window, the HARQ feedback information sent by the second terminal.

Abstract: Embodiments of the present disclosure provide timing advance (TA) obtaining methods and apparatuses. One example method includes generating, by a base station, an indication message and sending the indication message to UE, and receiving, by the UE, the indication message sent by the base station. The UE can then obtain a TA of a second carrier based on the indication message, where the second carrier is a carrier not used to transmit a PUSCH. Although the second carrier is a carrier not used to transmit a PUSCH, the TA of the second carrier can still be obtained.

Abstract: The present invention discloses an information transmission method, a device, and a system, and relates to the communications field, so as to resolve a problem that a receiving device has excessively large power consumption because the receiving device needs to continuously perform blind detection on a channel to determine a moment at which data transmission is started. A specific solution is: obtaining, by a network device, a start location of a first subframe, configuring a first field in downlink control information DCI of a second subframe, and sending, to user equipment, the first subframe and the second subframe that are adjacent to each other, where the first field is used to indicate the start location of the first subframe. The present invention is used for information transmission.
