Abstract: This application relates to the mobile communications field, and in particular, to a technology for obtaining a reference signal in a wireless communications system. In an example method for obtaining a reference signal, a terminal device obtains position offset information and a first sequence based on the position offset information. The terminal device demodulates, by using the first sequence, a control channel signal carried in a control channel resource set, to obtain downlink control information.

Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: This application relates to the field of wireless communications, and in particular, to a communication method, an apparatus, and a system in a wireless communications system. In the method, a network device and a terminal device determine M resource element group bundles in a control resource set. The network device sends a control channel on resources corresponding to the M resource element group bundles. The terminal device detects the control channel on the resources corresponding to the M resource element group bundles, where M is greater than or equal to 1. The control resource set includes B resource element group resource element group bundles. By using the method, resource configuration efficiency in a communications system is improved.
