Information configuration method, data receiving method, and device

說明書
The physical downlink control channel set includes a physical downlink control channel that may be used for the to-be-initially-transmitted downlink data.
The information about the first resource set group may be resource set information required by the UE for detecting a physical downlink control channel in the physical downlink control channel set. For example, the information about the first resource set group may include time-frequency resource configuration information of the physical downlink control channel set corresponding to the to-be-initially-transmitted downlink data, and the physical downlink control channel in the physical downlink control channel set may be a physical downlink control channel (PDCCH for short) or an enhanced physical downlink control channel (EPDCCH for short). One resource set group may include one or more resource sets, and therefore, is referred to as one group. One resource set may include time-frequency resources used by the one or more physical downlink control channels. For example, one resource set corresponding to an EPDCCH may include one or more physical resource blocks or physical resource block pairs (PRB Pair for short), and one physical resource block pair includes two physical resource blocks in one subframe. Information about one resource set may include a time-frequency resource and/or a scrambling code used by a physical downlink control channel corresponding to the set. Scrambling codes of physical downlink control channels corresponding to different resource sets may be different. The UE may detect the physical downlink control channel in the physical downlink control channel set according to the information about the first resource set group, so as to implement receiving of control information corresponding to downlink data.
