1. A method of wireless communication, comprising:
- receiving, at a user equipment (UE), an adjusted random access response (RAR) comprising a resource block assignment for an uplink grant, a number of bits of the resource block assignment being adjusted at a base station based at least in part on a number of uplink resource blocks; and
interpreting, at the UE, the adjusted resource block assignment by truncating or expanding a fixed resource block assignment of the adjusted RAR based on an uplink bandwidth configuration, the fixed resource block assignment being truncated when a number of uplink resource blocks is less than or equal to a threshold and the fixed resource block assignment being expanded when the number of uplink resource blocks is greater than the threshold.

Abstract
Methods and apparatuses for wireless communication are provided. In an aspect, an uplink grant is received which includes a resource block assignment. The resource block assignment with a length adjustment is interpreted based on an uplink bandwidth configuration. In another aspect, a length adjustment is determined for an uplink grant. The length adjustment is based on an uplink bandwidth configuration. A resource block assignment is encoded based on the length adjustment, and the uplink grant including the resource block assignment is transmitted.
