摘要： This application provides a synchronization signal sending method, an apparatus and a computer program product. The sending method includes:
determining a target frequency resource, wherein 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 2^m times 180 kHz, and m is a preset nonnegative integer; and
sending a synchronization signal by using the target frequency resource.
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： A method, a base station, a User Equipment (UE) and a system for sending and receiving Physical Downlink Control Channel (PDCCH) signaling are disclosed. The method for sending PDCCH signaling includes the following steps: the base station determines locations of a first search space and second search space; and the base station sends PDCCH signaling exclusive of a Carrier Indication Field (CIF) to the UE in a physically overlapped region between the first search space and the second search space if the physically overlapped region exists and length of PDCCH signaling exclusive of a CIF in the first search space is equal to length of PDCCH signaling inclusive of a CIF in the second search space. With the method, the base station, the UE, and the system disclosed herein, the scheduling uncertainty of the base station is prevented, and the parsing error of the UE is prevented.

摘要： A method for mapping a control channel, a method for detecting a control channel and devices thereof are provided. The method for mapping a control channel includes: for the same aggregation level, according to a signaling length of a control channel corresponding to a component carrier, determining a corresponding search space for at least two control channels that have the same signaling length, so as to enable the at least two control channels that have the same signaling length to use the same search space, and mapping the at least two control channels that have the same signaling length to the determined corresponding search space; and/or, determining corresponding search spaces for at least two control channels that have different signaling lengths respectively, so as to enable the at least two control channels that have different signaling lengths to use the different search spaces in at least one time transmission unit, and respectively mapping the at least two control channels that have different signaling lengths to the determined corresponding search spaces. Therefore, conflicts between the control channels are reduced, and the number of times of blind detection of the control channels is also reduced.
