The method includes: acquiring resource indication information about a first common search area of a control channel, or resource indication information about a first common search area and resource indication information about at least one second common search area; and determining, according to the resource indication information about the first common search area, or the resource indication information about the first common search area and the resource indication information about at least one second common search area, a location of the first common search area, or locations of the first common search area and at least one second common search area. ## Claims ### Claim 1 A method for processing a common search area by a base station, comprising: determining a position of a first common search area and a position of a second common search area; and sending to a user equipment device, a first resource indication and a second resource indication, wherein the first resource indication is for determining the position of the first common search area and the second resource indication is for determining the position of the second common search area; wherein among a type of control signaling for scheduling a system message, a type of control signaling for scheduling a paging message, a type of control signaling for scheduling a random access signaling and a type of control signaling carrying power control command, the first common search area is a search area including the type of control signaling for scheduling the system message and the second common search area is a search area including the type of control signaling for scheduling the paging message, the type of control signaling for scheduling the random access signaling or the type of control signaling carrying power control command. ### Claim 2 (depends on 1) The method according to claim 1, wherein the first resource indication is carried in physical broadcast channel (PBCH) or radio resource control (RRC) signaling and the second resource indication is carried in RRC signaling. ### Claim 3 (depends on 1) The method according to claim 1, wherein the first resource indication comprises an amount of resource blocks occupied by the first common search area and the start position of the first common search area. ### Claim 4 (depends on 3) The method according to claim 3, wherein the first resource indication comprises bandwidth resource information. ### Claim 5 A base station, comprising: a transmitter and a processor coupled with the transmitter; wherein the processor is configured to determine a position of a first common search area and a position of a second common search area; wherein the transmitter is configured to send to a user equipment device, a first resource indication and a second resource indication, wherein the first resource indication is for determining the position of the first common search area and the second resource indication is for determining the position of the second common search area; wherein among a type of control signaling for scheduling a system message, a type of control signaling for scheduling a paging message, a type of control signaling for scheduling a random access signaling and a type of control signaling carrying power control command, the first common search area is a search area including the type of control signaling for scheduling the system message and the second common search area is a search area including the type of control signaling for scheduling the paging message, the type of control signaling for scheduling the random access signaling or the type of control signaling carrying power control command. ### Claim 6 (depends on 5) The base station according to claim 5, wherein the first resource indication is carried in physical broadcast channel (PBCH) or a radio resource control (RRC) signaling and the second resource indication is carried in a RRC signaling. ### Claim 7 (depends on 5) The base station according to claim 5, wherein the first resource indication comprises an amount of resource blocks occupied by the first common search area and the start position of the first common search area. ### Claim 8 (depends on 7) The base station according to claim 7, wherein the first resource indication comprises bandwidth resource information. ### Claim 9 A non-transitory readable medium, comprising: a memory; and program instructions stored in the memory, wherein the program instructions are executed to perform the method of: determining a position of a first common search area and a position of a second common search area; and sending to a user equipment device, a first resource indication and a second resource indication, wherein the first resource indication is for determining the position of the first common search area and the second resource indication is for determining the position of the second common search area; wherein among a type of control signaling for scheduling a system message, a type of control signaling for scheduling a paging message, a type of control signaling for scheduling a random access signaling and a type of control signaling carrying power control command, the first common search area is a search area including the type of control signaling for scheduling the system message and the second common search area is a search area including the type of control signaling for scheduling the paging message, the type of control signaling for scheduling the random access signaling or the type of control signaling carrying power control command. ### Claim 10 (depends on 9) The medium according to claim 9, wherein the first resource indication is carried in physical broadcast channel (PBCH) or radio resource control (RRC) signaling and the second resource indication is carried in RRC signaling. ### Claim 11 (depends on 9) The medium according to claim 9, wherein the first resource indication comprises an amount of resource blocks occupied by the first common search area and the start position of the first common search area. ### Claim 12 (depends on 11) The medium according to claim 11, wherein the first resource indication comprises bandwidth resource information.
