Message repetition for random access procedure

Abstract:

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information associated with a random access response (RAR) during an RAR window. The UE may attempt to receive a single instance of the control information and, in some cases, may be unable to receive and decode the single instance of the control information. The base station may configure a portion of the RAR window to support transmitting repeating instances of the control information. The UE may identify a quantity of instances of the control information and combine the quantity of instances. The UE may successfully decode the combined quantity of repetitions and identify a location for receiving the RAR based on decoding the combined instances of control information.
