Abstract
Systems and methods relating to transmission and reception of a Random Access Response (RAR) message to a wireless device (e.g., a User Equipment (UE)) in a manner that is particularly well-suited for, but not limited to, reduced bandwidth devices, such as Machine Type Communication (MTC) devices, are disclosed. In some embodiments, a method of operation of a wireless device to perform random access to a cellular communications network comprises transmitting a random access preamble on a physical random access channel and determining, from a random access preamble index of the random access preamble, one of a random access response resource and a channel to monitor for a transmission of an indication of the random access response resource. The method further comprises receiving a random access response on the random access response resource.
