Patent ID: 10492198

Abstract:
Disclosed are an uplink access method, device, and terminal and a base station. The method comprises: a terminal requests, according to obtained uplink access configuration information, uplink access to one or more first base stations; the terminal receives uplink access related information responded from the one or more first base stations, wherein the uplink access related information comprises downlink synchronization related information for performing downlink synchronization; and the terminal selects, according to the obtained uplink access related information, a first base station to perform uplink access. The technical solution of the present invention enables a terminal to accomplish downlink synchronization with one or more selected first base stations while accomplishing uplink access, and to obtain some system messages of the first base stations to which the terminal is connected. In this way, there is no need for the one or more first base stations to periodically transmit synchronization signals and certain system messages, and consequently, system power consumption for transmitting a synchronization signal and a system message is greatly reduced, thereby saving system resources.
