Abstract: This application relates to the wireless communications field, and discloses a random access method and apparatus, to resolve a problem of how a terminal device selects an uplink to perform random access. The method includes: selecting, by a terminal device, a first uplink from at least two preconfigured uplinks to perform random access; and selecting, by the terminal device when random access performed by using the first uplink fails, a second uplink from the at least two uplinks to perform random access, where the at least two uplinks are communications links between the terminal device and a first network device, the first network device and the terminal device are located in a same cell, the first uplink is a normal uplink NUL, and the second uplink is a supplementary uplink SUL. In this way, the terminal device selects an uplink to perform random access.

Abstract: A measurement configuration method includes a network device that determines when a bandwidth part (BWP) occupied by a terminal device is switched from a first BWP to a second BWP. The network device sends first information to the terminal device, indicating whether configuration information of a first measurement window takes effect when the terminal device occupies the second BWP and indicating whether the first measurement window is configured for the first BWP.

Abstract: This application provides a method for signal reception and transmission in a measurement gap. User equipment (UE) obtains, in dual connectivity, a measurement configuration delivered by a base station, and determines a first cell group in which signal reception and transmission can be performed in the measurement gap; performs signal reception and transmission with the base station in the first cell group in the measurement gap; and performs inter-frequency or inter-RAT measurement in a second cell group. The second cell group is a cell group in which signal reception or transmission cannot be performed in the measurement gap. In the measurement gap, the base station and the UE can still receive and transmit signals in the first cell group, and radio frequency channels of the UE that support signal reception and transmission in the measurement gap can be fully used for performing signal reception and transmission.
