Narrowband selection for measurement reporting in random access

Abstract:

A method, a computer-readable medium, and an apparatus are provided for wireless communication at a User Equipment (UE). The UE receives a second random access message from the base station after transmitting a first random access message. The second random access message comprises a random access response (RAR) that indicates a narrowband to be used for receiving a fourth random access message. The apparatus determines whether to perform a measurement of the narrowband for the fourth random access message based on an amount of time between receiving the second random access message and transmitting a third random access message. The base station may determine whether the report comprises a measurement of the first narrowband or the second narrowband based on an amount of time between the second random access message and the third random access message or based on an indication in the third random access message.
