if the PDCCH order carries a dedicated access resource configured for the target user equipment, then after the target user equipment accesses successfully through the dedicated access resource, scheduling, by the base station, the target user equipment to receive the downlink data through the available public resource, wherein the available public resource is obtained by the target user equipment from the PHYConfig list according to the index number of the available public resource;
orif the PDCCH order does not carry the dedicated access resource configured for the target user equipment, then after the target user equipment accesses successfully, receiving, by the base station, an identifier C-RNTI of the target user equipment which is sent by the target user equipment; and
scrambling, by the base station, a physical downlink control channel with the C-RNTI, and indicating the user equipment, via the scrambled physical downlink control channel, to receive the downlink data through the available public resource.

5. A method for resource configuration, comprising:
-
receiving, by a user equipment, a public resource configuration sent by a base station through a broadcast channel, wherein the public resource configuration comprises a physical resource configuration list (PHYConfig list); sending, by a target user equipment of the user equipment, public resource requesting information to the base station, so that the base station obtains an available public resource, wherein the target user equipment is in a desynchronization state; receiving, by the target user equipment, an index number of the available public resource sent by the base station; performing, by the target user equipment, data transmission through the available public resource corresponding to the index number of the available public resource, wherein the available public resource is obtained by the target user equipment from the PHYConfig list according to the index number of the available public resource; wherein after receiving, by the user equipment, the public resource configuration sent by the base station through the broadcast channel, the method further comprises; when the base station needs to transmit downlink data to the target user equipment and an available public resource exists, receiving, by the target user equipment, an index number of the available public resource and a physical downlink control channel order (PDCCH order) sent by the base station; if the PDCCH order carries a dedicated access resource configured for the target user equipment, receiving, by the target user equipment, the downlink data through the available public resource according to a schedule of the base station, wherein the available public resource is obtained by the target user equipment from the PHYConfig list according to the index number of the available public resource;
orif the PDCCH order does not carry the dedicated access resource configured for the target user equipment then after the target user equipment accesses successfully sending by the target user equipment, an identifier C-RNTI of the target user equipment to the base station; receiving, by the target user equipment, the downlink data through the available public resource according to an indication of the base station. - View Dependent Claims (6, 7, 8)
