Abstract: A search space (hereinafter, CSS) for a control channel for scheduling a random access response may be configured by a system information block. A user equipment (UE) may attempt to receive a control channel for a random access response on the assumption that CSS is configured in accordance with a configuration based on the system information block. The UE may attempt to receive the control channel within a UE-specific search space (USS) by assuming that the USS is configured in accordance with the configuration of the CSS until a configuration for the USS is received.
