RANDOM ACCESS VIA AN ALTERNATIVE FREQUENCY RESOURCE

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first-attempt random access preamble to a base station via a first frequency resource. The first frequency resource may be within a first bandwidth part (BWP), a first component carrier (CC), a first frequency subband, or any combination thereof. If the UE fails to detect a random access response (RAR) for the first-attempt random access preamble within the time period, the UE may transmit a second-attempt random access preamble to the base station. In some examples, the UE may transmit the second-attempt random access preamble via a different, second frequency resource, which may be within a second BWP, a second CC, a second frequency subband, or any combination thereof. The base station may transmit an indication of the second frequency resource to the UE.
