<p>An information transmission method, network node, user equipment and system, which relate to the communication technology field, are disclosed in the embodiments of the present invention. The method, network node, user equipment and system can save the resource of common search space and increase the random access capacity. The method in the present invention comprises the following steps: receiving the Physical Random Access Channel (PRACH) message sent by the User Equipment (UE); determining the object search space according to the PRACH configuration information carried by the PRACH message, wherein the object search space is one of the at least two search spaces provided by the network node, and each search space corresponds to a group of PRACH configuration information; sending the downlink control message scheduling the random access acknowledgement message to the UE through the object search space. The embodiments of the present invention are mainly used in the information transmission procedure for random access.</p> |
