    摘要: This application provides a synchronization signal sending method and receiving method, and an apparatus. The sending method includes: determining a target frequency resource, where a frequency domain position of the target frequency resource is determined based on a frequency interval of synchronization channels, the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer; and sending a synchronization signal by using the target frequency resource. In the embodiments of this application, the frequency domain position of the frequency resource occupied by the synchronization signal is determined based on the frequency interval of synchronization channels, and the frequency interval of synchronization channels is 2m times a predefined frequency band width of the frequency resource of a predefined physical resource block. This is for the benefit of increasing a quantity of candidate frequency resources of the synchronization signal, thereby increasing available frequency domain mapping positions for the synchronization signal.

    摘要: 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.

    摘要: The present invention relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI (Channel State Information) trigger signaling, so that a base station transmits a CSI-RS (Channel State Information-Reference Signal) only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced, thereby improving the spectrum efficiency of the system.

    摘要: The present invention discloses a control information transmission method, user equipment, and a base station, and belongs to the field of wireless technologies. The method includes: acquiring, by user equipment, configuration information of an enhanced physical downlink control channel EPDCCH set; determining, by the user equipment according to the configuration information and from the EPDCCH set, at least one EPDCCH set in which an EPDCCH needs to be monitored; and monitoring, by the user equipment, an EPDCCH on a resource corresponding to the at least one EPDCCH set, to acquire control information sent by a base station. In the present invention, because the at least one EPDCCH set is only a part of EPDCCH sets corresponding to EPDCCH common search space, and this part may be monitored by users that have different capabilities in a system, common control information that needs to be detected by all the users may be sent on this part of the EPDCCH sets; therefore, repetitious sending of the common control information can be avoided, control signaling overheads can be reduced, and spectrum utilization can be improved.
